Description

TECHNICAL AREA

[0001] The invention relates to connection structures of connectors. TECHNICAL BACKGROUND

[0002] JP 2023-139357 A describes a conventional connector connection structure. The connection structure comprises a floating connector mounted on a printed circuit board and a mating connector.

[0003] The floating connector comprises a housing and a multitude of terminals. Within the housing, numerous compartments are provided to accommodate the individual terminals. An upper wall of the housing features numerous top openings that connect to these compartments.

[0004] Each terminal comprises a fixed section, a lower contact section, an inverted Ω-shaped upper contact section, and a generally L-shaped spring section. The fixed section is attached to a lower section of the corresponding housing space of the enclosure for mounting on a lower wall of the enclosure. The lower contact section extends forward from the corresponding fixed section and is bent downward such that a lower surface of the lower contact section is at the same level as a bottom surface of the lower wall of the enclosure. The bottom surface of the lower wall of the enclosure is mountable on the printed circuit board (PCB), and the lower contact section is connectable to the PCB. The upper contact section comprises a generally U-shaped main section, a first end section on the front, and a second end section on the rear.The spring section comprises a first spring element and a second spring element. The first spring element, which is a plate-like section suspended from the second end section of the upper contact section, extends in a vertical and a horizontal direction. The second spring element, which is a plate-like section suspended from a lower end of the corresponding first spring element on the corresponding attached section, extends in a vertical and a horizontal direction.

[0005] The mating connector can be connected to the floating connector at a position that is offset forward from a predetermined connection position relative to the floating connector. In this case, the mating connector terminals are inserted from above through the respective upper openings of the floating connector housing into the respective housing cavities and into the respective main sections of the upper contact sections of the floating connector terminals. At this point, the first spring elements of the multiple terminals of the floating connector deform elastically, causing them to tilt forward, and the second spring elements of the terminals deform elastically, causing them to lift upward, so that the main sections of the upper contact sections of the terminals are displaced forward by following the respective terminals of the mating connector.

[0006] The mating connector can also be connected to the floating connector at a position that is offset rearward from the predetermined connection position relative to the floating connector. In this case, the terminals of the mating connector are inserted from above through the respective upper openings of the floating connector housing into the respective housing compartments and into the respective main sections of the upper contact sections of the floating connector terminals.At this point, the first spring elements of the multitude of terminals of the floating connector deform elastically, causing them to tilt backwards, and the second spring elements of the terminals deform elastically, causing them to lower downwards, so that the main sections of the upper contacting sections of the terminals are shifted backwards by following the respective terminals of the mating connector.

[0007] Thus, the floating connector is designed such that the elastic deformation of the spring sections of the plurality of connections causes the main sections of the upper contacting sections of the plurality of connections to float forward or backward in accordance with the displacement of the mating connector in one direction. SUMMARY OF THE INVENTION Technical Problem

[0008] The floating connector described above is structured such that the multiple contacts of the mating connector are inserted vertically into the respective main sections of the upper contact areas of the floating connector's contacts. Such a structure can result in a partially connected state, in which the multiple contacts of the mating connector are not fully inserted into the respective main sections of the upper contact areas of the floating connector's contacts.

[0009] The invention provides a connection structure of connectors that can resolve the partially connected state. Solution to the problem

[0010] The connection structure (combination structure) of connectors according to one aspect of the invention comprises a floating connector and a mating connector. The floating connector comprises a connector part that can be detachably connected to the mating connector in a first direction, and A support device. The support device movably supports the connector part in a direction encompassing at least one component in the first direction. The connector part is transferable from a partially connected state to a fully connected state with respect to the mating connector. The partially connected state is a state in which the connector part is at least partially mechanically connected to the mating connector from one side in the first direction, but is movable to the other side in the first direction relative to the mating connector. The fully connected state is a state in which the connector part is fully mechanically and electrically connected to the mating connector from one side in the first direction and is not movable to the other side in the first direction relative to the mating connector.Either the connector part or the mating connector is a primary connector, and the other is a secondary connector. The primary connector includes a rotary lever that can rotate between a first and a second state, and the secondary connector includes a counter-bearing.

[0011] The connector part is moved from the first state to the second state by rotating the rotary lever in order to push the abutment with the rotary lever from one side of the secondary connector encompassing the abutment in the first direction, relative to the mating connector to the other side in the first direction, and is transferred from the half-connected state to the fully connected state. Advantageous effects of the invention

[0012] In the connection structure (combination) of connectors of such aspect, it is possible even in the semi-connected state to connect the connector part to the mating connector in the fully connected state by turning the rotary lever and pressing the abutment with the rotary lever from the side of the other connector in the first direction.

[0013] In the above brief description of the drawings and the description of the embodiments that follows, relative spatial terms such as "upper," "lower," "top," "bottom," "left," "right," "front," "back," etc., are used for the convenience of the expert reader and refer to the orientations of the connection structures of connectors and their components as shown in the drawings. The use of these terms is not intended to restrict the invention in any way, whether used during its manufacture, shipping, storage, or sale, or during the assembly of its components, or when it is incorporated into or combined with other devices. DESCRIPTION OF EXECUTION FORMS

[0014] A multitude of embodiments of the invention, comprising the first and second embodiments and variants thereof, will now be described. It should be noted that the components of the embodiments and their variants to be described can be combined in any possible way. It should also be noted that the materials, shapes, dimensions, numbers, arrangements, etc., of the components of the embodiments and their variants to be described are shown only as examples and can be modified in any way, as long as the same functions can be fulfilled. First embodiment

[0015] In the following, a connection structure (combination) CB1 of connectors according to a plurality of embodiments, comprising the first embodiment of the invention and variants thereof, is described with reference to the Fig. 1A to 11B are described. Fig. 1A to 3B represent the connection structure CB1 of the first embodiment. Fig. 1A to 7B represent a floating connector FC of the connection structure CB1 of the first embodiment. Fig. 1A to 3B and the Fig. 8A to 11B represent a first mating connector MC1 and a second mating connector MC2 of the connection structure CB1 of the first embodiment. Fig. 1A to 2D represent a first printed circuit board B1 and a second printed circuit board B2 of the interconnection structure CB1 of the first embodiment.

[0016] The Fig. 1A to 2A, 2C to 5A, 5D to 5C, 6A to 9C, and 10A to 11B show a Y-Y' direction (first direction). The Y-Y' direction comprises a Y' direction (one side in the first direction) and a Y direction (the other side in the first direction). Fig. 1A to 2B, 3A to 5C, 6A to 9A, and 9D to 11B show a Z-Z' direction (second direction). The Z-Z' direction is essentially orthogonal to the Y-Y' direction and comprises a Z' direction (one side in the second direction) and a Z direction (the other side in the second direction). Fig. 1A and 1B, 2B to 4D, 5B to 8D, and 9B to 11B show an X-X' direction (third direction). The X-X' direction is essentially orthogonal to the Y-Y' and Z-Z' directions and comprises an X direction (one side in the third direction) and an X' direction (the other side in the third direction).

[0017] The interconnection structure CB1 comprises the floating connector FC (which can simply be referred to as "the connector FC") and a first mating connector MC1 and a second mating connector MC2. The interconnection structure CB1 may also include a first printed circuit board B1 and a second printed circuit board B2. Details of these components are now described.

[0018] The FC connector includes at least one relay terminal 200 (which can simply be referred to as "the at least one terminal 200"). The at least one terminal 200 can be a single terminal 200 or a plurality of terminals 200. For the sake of simplicity, the at least one terminal 200 is described as a plurality of terminals 200. However, even in a case where a single terminal 200 is provided, the terminal 200 can be configured similarly to any of the terminals 200.

[0019] Each of the terminals 200 is formed by an electrically conductive material. Each terminal 200 comprises a first contacting section 210a, a first retainable section 220a, a second contacting section 210b, a second retainable section 220b, and an elastically deformable section 230. Each terminal 200 may further comprise a first connecting section 240a and a second connecting section 240b.

[0020] The first removable section 220a can be connected by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B), a rod (not shown) or a tube (not shown) extending in the Y-Y' direction. The first holdable section 220a can generally be U-shaped in a sectional view along the Z-Z' and X-X' directions and extend in the Y-Y' direction.

[0021] The second holdable section 220b is arranged relative to the first holdable section 220a on the Z-direction side. The second holdable section 220b can be connected by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B), a rod (not shown) or a tube (not shown) extending in the Y-Y' direction. The second holdable section 220b can generally be U-shaped in a sectional view along the Z-Z' and X-X' directions and extend in the Y-Y' direction.

[0022] The first contact section 210a only needs to extend from the first supportable section 220a in the Y direction. For example, the first contact section 210a can be formed by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B), a rod (not shown) or a tube (not shown) extending from the first holdable section 220a in the Y direction. The first contacting section 210a may have a forked shape extending from the first holdable section 220a in the Y direction and may include a first and a second contacting arm (not shown).

[0023] The second contact section 210b is arranged relative to the first contact section 210a on the Z-direction side. The second contact section 210b only needs to extend from the second mountable section 220b in the Y-direction. For example, the second contact section 210b can be formed by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B), a rod (not shown) or a tube (not shown) extending from the second holdable section 220b in the Y direction. The second contacting section 210b may have a forked shape extending from the second holdable section 220b in the Y direction and may include a first and a second contacting arm (not shown).

[0024] The elastically deformable section 230 is provided between the first holdable section 220a and the second holdable section 220b and is elastically deformable in a direction comprising a component in at least one direction of the Z-Z', X-X', or Y-Y' direction (this direction can simply be referred to as "the component of the direction comprising the at least one direction"). The component of the direction comprising the at least one direction can comprise components in a plurality of directions from the Z-Z', X-X', and Y-Y' directions.For example, the elastically deformable section 230 can be generally laterally oriented in a sectional view along the Z-Z' and Y-Y' directions as a U-shape, generally laterally oriented arc, or generally laterally oriented as a V-shape, and can be elastically deformable in a direction comprising one component of one direction of the Z-Z', X-X', or Y-Y' direction, in a direction comprising two components of the Z-Z', X-X', and Y-Y' directions, or in a direction comprising three components of the Z-Z', X-X', and Y-Y' directions. The elastically deformable section 230 comprises a first end section 231 on the Z'-direction side, a second end section 232 on the Z-direction side, and an upper section 233.If the second end section 232 is displaced from the first end section 231 in a direction encompassing a Z-direction component (moves away from it), the elastically deformable section 230 deforms elastically in the direction encompassing the Z-direction component. If the second end section 232 is displaced in a direction encompassing a Z'-direction component towards the first end section 231 (moves in its direction), the elastically deformable section 230 deforms elastically in the direction encompassing the Z'-direction component. If the second end section 232 is displaced from the first end section 231 in a direction encompassing a Y-direction component, the elastically deformable section 230 deforms elastically in the direction encompassing the Y-direction component.If the second end section 232 is displaced from the first end section 231 in a direction including a Y'-direction component, the elastically deformable section 230 deforms elastically in the direction including the Y'-direction component. If the second end section 232 is displaced from the first end section 231 in a direction including an X-direction component, the elastically deformable section 230 deforms elastically in the direction including the X-direction component. If the second end section 232 is displaced from the first end section 231 in a direction including an X'-direction component, the elastically deformable section 230 deforms elastically in the direction including the X'-direction component.

[0025] The first connecting section 240a connects the elastically deformable section 230 and the first fixable section 220a, and the second connecting section 240b connects the elastically deformable section 230 and the second fixable section 220b. The first connecting section 240a can, for example, be formed by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B) or a rod (not shown) extending from the first end section 231 of the elastically deformable section 230 to the rear end on the Y'-direction side of the first retainable section 220a. The second linking section 240b can, for example, be formed by a plate (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B) or a rod (not shown) extending from the second end section 232 of the elastically deformable section 230 to the rear end on the Y'-direction side of the second holdable section 220b.

[0026] Each connection 200 described above can, for example, be produced by a rolling process. The rolling process comprises repeatedly performing a rolling step in which a metal material is passed between rolling rolls to obtain a thin sheet, and subsequently punching and cutting the sheet into a predetermined shape for the connection or performing a similar step. In this case, each connection 200 further comprises the following embodiment (1) or (2). It should be noted that the X-X' direction is a thickness direction of the elastically deformable section 230 of each connection 200. In other words, the X-X' direction is a thickness direction of the metal material that forms the elastically deformable section 230 of each connection 200.

[0027] (1) Each connection 200 has a first surface on the X-direction side and a second surface on the X'-direction side, and the first and second surfaces are generally flat and extend in the Z-Z' and X-X' directions (not shown). The first and second surfaces of each connection 200 are rolled surfaces. In particular, the elastically deformable section 230, the first connecting section 240a, the second connecting section 240b, the first retainable section 220a, and the second retainable section 220b of each connection 200 are formed by the plate described above and each has a first surface on the X-direction side and a second surface on the X'-direction side, the surfaces being generally flat, rolled surfaces.The first contact section 210a of each terminal 200 is formed by the plate or two contact arms described above and has a first surface 211a on the X-direction side and a second surface 212a on the X'-direction side, which are generally flat, rolled surfaces. The second contact section 210b of each terminal 200 is formed by the plate or two contact arms described above and has a first surface 211b on the X-direction side and a second surface 212b on the X'-direction side, the surfaces being generally flat, rolled surfaces.

[0028] (2) The first connecting section 240a of each terminal 200 of the above-mentioned embodiment (1) is at least partially (i.e., partially or completely) bent or curved such that the first surface 211a and the second surface 212a of the first contacting section 210a are inclined in a first inclined direction comprising components of the Z-Z' and the X-X' directions, and / or the second connecting section 240b is at least partially (i.e., partially or completely) bent or curved such that the first surface 211b and the second surface 212b of the second contacting section 210b are inclined in a second inclined direction comprising components of the Z-Z' and the X-X' directions (see Fig. 2A, 3A, 3B, 5A, and 6A to 7B). The first and second faces of the first holdable section 220a are also inclined in the first oblique direction, similar to the first face 211a and the second face 212a of the first contacting section 210a. The first and second faces of the second holdable section 220b are also inclined in the second oblique direction, similar to the first face 211b and the second face 212b of the second contacting section 210b. The first linking section 240a may be curved in a general arc shape or a general U-shape projecting in the X or X' direction, or may be curved in a general V-shape projecting in the X or X' direction. The second linking section 240b may be curved in a general arc shape or a general U-shape projecting in the X or X' direction, or may be curved in a general V-shape projecting in the X or X' direction.The first and second surfaces of the elastically deformable section 230 of each connection 200 generally remain flat surfaces extending in the Z-Z' and Y-Y' directions.

[0029] The first inclined direction and the second inclined direction can be the same direction, and the first surface 211a and the second surface 212a of the first contacting section 210a can be inclined in the same way as the first surface 211b and the second surface 212b of the second contacting section 210b (see Fig. 2A, Fig. 3A, Fig. 3B, Fig. 5A, and 6A to 7B). Alternatively, the first inclined direction and the second inclined direction can be different directions, and the first surface 211a and the second surface 212a of the first contact section 210a can differ in inclination from the first surface 211b and the second surface 212b of the second contact section 210b (not shown). In the former case, each terminal 200 can be shaped to have such a double rotational symmetry (see Fig. 7A and Fig. 7B), that when viewed from the Y-direction side along an imaginary line P, a shape of each terminal 200 before a 180-degree rotation about an axis of rotation overlaps, but does not necessarily overlap, a shape of each terminal 200 after a 180-degree rotation about the axis of rotation. The axis of rotation is the imaginary line P extending in the Y-Y' directions essentially through the center of each terminal 200 (see Fig. 7A and Fig. 7B).

[0030] Each connection 200 described above can be manufactured not by the rolling process, but by another known method for manufacturing connections, such as a photolithography process or an inkjet process. In this case, each connection 200 can have the configuration (1) or (2) described above. Alternatively, the first and second surfaces of the elastically deformable section 230 of each connection 200 can be generally flat surfaces extending in the Z-Z' and Y-Y' directions; the first connecting section 240a and the second connecting section 240b of each connection 200 can be formed by a plate or a rod with a configuration that differs from the configurations (1) and (2) described above; the first retainable section 220a and the second retainable section 220b of each connection 200 can be formed by a plate, a rod,a tube or a generally U-shaped element with a configuration that differs from the configurations (1) and (2) described above, and the first contacting section 210a and the second contacting section 210b of each connection 200 can be formed by a plate, a rod, a tube, or two contacting arms with a configuration that differs from the configurations (1) or (2) described above. Alternatively, the elastically deformable section 230, the first connecting section 240a, the second connecting section 240b, the first retainable section 220a, the second retainable section 220b, the first contacting section 210a, and the second contacting section 210b of each connection 200 can have any of the configurations described above that differ from the configurations (1) and (2) described above.

[0031] If each connection 200 has the configuration (1) or (2) described above, the upper section 233 of the elastically deformable section 230 of each connection 200 may have a dimension in the Y-Y' direction that is smaller than the dimension in the Z-Z' direction of the first end section 231 and the second end section 232 of the elastically deformable section 230 of each connection 200. In this case, an end section on the Y-direction side and / or an end section on the Y'-direction side of the upper section 233 of the elastically deformable section 230 of each connection 200 may be cut away (see Fig. 7A and Fig. 7C). Alternatively, the dimension in the Y-Y' direction of the upper section 233 of the elastically deformable section 230 of each connection 200 may be substantially equal to or greater than the dimension in the Z-Z' direction of the first end section 231 and the second end section 232 of the elastically deformable section 230 of each connection 200.

[0032] The first linking section 240a and the second linking section 240b can be omitted. In this case, the first end section 231 of the elastically deformable section 230 can be linked to the first fixable section 220a, and the second end section 232 of the elastically deformable section 230 can be linked to the second fixable section 220b.

[0033] The connector FC further comprises a first connector part FC1. The first connector part FC1 comprises a first body 100a, the first retainable sections 220a of the plurality of connections 200, and the first contacting sections 210a of the plurality of connections 200. The first connector part FC1 may further comprise the first linking sections 240a (if provided) of the plurality of connections 200.

[0034] The first body 100a must only be formed by an insulating material (e.g. an insulating resin or the like) and be designed such that it holds the first holdable sections 220a of the plurality of connections 200 at intervals in the X-X' direction.

[0035] The first body 100a comprises a main section 110a of the first body. The main section 110a of the first body holds the first holdable sections 220a of the plurality of terminals 200 at intervals in the X-X' direction. The first contact sections 210a of the plurality of terminals 200 project at least partially from the main section 110a of the first body, or are at least partially exposed from it, such that they are visible from the Y-direction side. The main section 110a of the first body and the plurality of terminals 200 may further have one of the following configurations (3-1) to (3-4).

[0036] (3-1) The main section 110a of the first body comprises a block 110a1 and a table 110a2. The block 110a1 of the main section 110a of the first body extends in the Y-Y' direction and is divided by a polygonal prism (e.g., a quadrilateral prism (see Fig. 5A), a hexagonal prism (not shown) or the like) or a cylinder (not shown). The table 110a2 (see Fig. 5A) of the main section 110a of the first body extends from block 110a1 of the main section 110a of the first body in the Y' direction.

[0037] Block 110a1 of the main section 110a of the first body is provided with a plurality of mounting holes 111a extending through block 110a1 in the Y-Y' direction and spaced at intervals in the X-X' direction. Table 110a2 of the main section 110a of the first body is provided with a plurality of mounting grooves 112a spaced at intervals in the X-X' direction and on the Y'-direction side relative to the plurality of mounting holes 111a. The plurality of mounting grooves 112a opens in the Y, Y', and Z directions. The first mountable sections 220a of the plurality of connectors 200 are securely received from the Y'-direction side in the plurality of mounting holes 111a and the plurality of mounting grooves 112a. Thus, the first holdable sections 220a of the multitude of connections 200 are held at intervals in the X-X' direction in the first body 100a.The first contact sections 210a of the plurality of terminals 200 project at least partially from the plurality of mounting holes 111a of the first body 100a in the Y-direction. For example, the first contact sections 210a of the plurality of terminals 200 can project completely from the plurality of mounting holes 111a in the Y-direction. Alternatively, sections on the Y'-direction side of the first contact sections 210a of the plurality of terminals 200 can be accommodated in the plurality of mounting holes 111a, and sections on the Y-direction side of the first contact sections 210a of the plurality of terminals 200 can project from the plurality of mounting holes 111a in the Y-direction.

[0038] (3-2) The block 110a1 of the main section 110a of the first body can further be provided with a plurality of connecting holes (not shown) on the Y-direction side relative to the plurality of mounting holes 111a. The plurality of connecting holes is arranged in the X-X' direction at equal intervals to the plurality of mounting holes 111a, extends through the plurality of mounting holes 111a, and opens in the Y-direction. In this case, the first contact sections 210a of the plurality of terminals 200 are arranged in the plurality of connecting holes of the first body 100a and are at least partially exposed by, or project from, the plurality of connecting holes in the Y-direction.For example, the first contact sections 210a of the plurality of terminals 200 may be completely enclosed within the plurality of connection holes, and all or part of the first contact sections 210a of the plurality of terminals 200 on the Y'-direction side may be exposed by the plurality of connection holes in the Y direction. Alternatively, parts of the first contact sections 210a of the plurality of terminals 200 on the Y'-direction side may be enclosed within the plurality of connection holes, and parts of the first contact sections 210a of the plurality of terminals 200 on the Y direction may protrude from the plurality of connection holes.

[0039] (3-3) The main section 110a of the first body can include the plurality of mounting holes 111a or the plurality of mounting grooves 112a (not shown). In this case, the first mountable sections 220a of the plurality of terminals 200 are securely received in the plurality of mounting holes 111a or the plurality of mounting grooves 112a from the Y'-direction side. This embodiment also allows the first mountable sections 220a of the plurality of terminals 200 to be mounted at intervals in the X-X' direction in the first body 100a. The first contacting sections 210a of the plurality of terminals 200 project at least partially in the Y direction from the plurality of mounting holes 111a or the plurality of mounting grooves 112a of the first body 100a.For example, the first contact sections 210a of the plurality of terminals 200 can project completely in the Y-direction from the plurality of mounting holes 111a or the plurality of mounting slots 112a. Alternatively, sections on the Y'-direction side of the first contact sections 210a of the plurality of terminals 200 can be included in the plurality of mounting holes 111a or the plurality of mounting slots 112a, and sections on the Y-direction side of the first contact sections 210a of the plurality of terminals 200 can project in the Y-direction from the plurality of mounting holes 111a or the plurality of mounting slots 112a. It should be noted that the table 110a2 can be omitted if the plurality of mounting slots 112a is not provided. If the multiple mounting holes 111a are not provided, block 110a1 can be omitted.

[0040] (3-4) The main section 110a of the first body can include the plurality of mounting holes 111a or the plurality of mounting slots 112a and the plurality of connecting holes (not shown). The plurality of connecting holes is provided in block 110a1 of the main section 110a of the first body and is arranged in the X-X' direction at the same intervals as the plurality of mounting holes 111a or the plurality of mounting slots 112a. The connecting holes are connected to the plurality of mounting holes 111a or the plurality of mounting slots 112a and open in the Y direction. In this case, the first mountable sections 220a of the plurality of connections 200 are securely received in the plurality of mounting holes 111a or the plurality of mounting slots 112a from the Y'-direction side.This configuration also allows the first retainable sections 220a of the plurality of connections 200 to be retained at intervals in the X-X' direction within the first body 100a. The first contacting sections 210a of the plurality of connections 200 are at least partially arranged within the plurality of connection holes of the first body 100a and are at least partially exposed to or project from the plurality of connection holes in the Y direction. For example, the first contacting sections 210a of the plurality of connections 200 can be completely enclosed within the plurality of connection holes, and all or parts of the first contacting sections 210a of the plurality of connections 200 on the Y-direction side can be exposed to the plurality of connection holes in the Y direction.Alternatively, sections on the Y'-direction side of the first contact sections 210a of the plurality of terminals 200 can be included in the plurality of connection holes, and sections on the Y'-direction side of the first contact sections 210a of the plurality of terminals 200 can project in the Y direction from the plurality of connection holes. It should be noted that the table top 110a2 can be omitted if the plurality of mounting slots 112a is not provided. If the plurality of mounting holes 111a is not provided, the block 110a1 can be omitted.

[0041] The first retainable sections 220a of the plurality of connections 200 are retained in the first body 100a, such that the first contacting sections 210a, the second contacting sections 210b, the elastically deformable sections 230, the first linking sections 240a (if provided) and the second linking sections 240b (if provided) of the plurality of connections 200 are arranged at intervals in the X-X' direction.

[0042] The first body 100a can further comprise a plurality of first partitions 120a.

The plurality of first partitions 120a comprises a plurality of groups of two adjacent first partitions 120a that are adjacent in the X-X' direction. If the first connecting sections 240a of the plurality of connections 200 are provided, each of the first connecting sections 240a of the plurality of connections 200 is arranged and guided between the two adjacent partitions 120a of each group, such that it is movable in the direction encompassing the component of the at least one direction.If the first linking sections 240a of the plurality of connections 200 are not provided, the plurality of first partition walls 120a can be omitted, or alternatively, each of the first end sections 231 of the elastically deformable sections 230 of the plurality of connections 200 can be arranged and guided between the two adjacent partition walls 120a of each group, such that it is movable in the direction encompassing the component of the direction comprising at least one direction.

[0043] The first body 100a can further comprise a plate 130a and / or two side walls 140a. The plate 130a extends from the main section 110a of the first body in the Y' direction. The two side walls 140a comprise one side wall 140a on the X-direction side and one side wall 140a on the X'-direction side. The side wall 140a on the X-direction side is positioned on the X-direction side relative to the main section 110a of the first body and the plate 130a. The side wall 140a on the X'-direction side is positioned on the X'-direction side relative to the main section 110a of the first body and the plate 130a.

The first sheath 300a can be formed by an electrically conductive material (e.g., a metal plate or the like) or can comprise an insulating material (e.g., an insulating resin or the like) and metal vapor-deposited onto an inner or outer surface of the insulating material. The first sheath 300a comprises a first sheath body 310a. The first sheath body 310a has a general ring shape (a polygonal ring shape, such as a general quadrilateral ring shape (see Figure 1)) in a sectional view along the Z-Z' and X-X' directions. Fig. 2B and 5A to 6B) or a general circular ring shape (not shown) or a general U-shape (not shown). The first sheath body 310a extends in the Y-Y' direction. The first sheath body 310a has, in cross-section along the Z-Z' and XX directions, an internal shape and size that correspond in cross-section along the Z-Z' and XX directions to an external shape and size of the first body 100a. The first sheath body 310a at least partially accommodates the first body 100a from the Y'-direction side. Accordingly, the first contacting sections 210a and the first retainable sections 220a of the plurality of terminals 200 are arranged at least partially within the first sheath body 310a. The first mantle body 310a has a dimension in the Y-Y' direction that is larger than the dimension in the Y-Y' direction of the first body 100a.A section of the first sheath body 310a, located relative to the first body 100a on the Y-direction side, defines a first connection space. It should be noted that if the first contact sections 210a of the plurality of terminals 200 project at least partially from the first body 100a, the first contact sections 210a are located at least partially within the first connection space of the first sheath body 310a.

[0045] The first cladding 300a can further comprise at least one first wall 320a. The at least one first wall 320a extends from the first cladding body 310a in the Z-direction. For example, the at least one first wall 320a can comprise two first walls 320a. The two first walls 320a comprise one first wall 320a on the X-direction side (one of the first walls 320a) and one first wall 320a on the X'-direction side (the other first wall 320a). The first wall 320a on the X-direction side and the first wall 320a on the X'-direction side can be formed by cutting out parts (e.g., a wall on the Z-direction side) of the first shell body 310a and bending the parts towards the Z-direction side, or alternatively, they can extend from the wall on the X-direction side or the wall on the X'-direction side of the first shell body 310a into the Z-direction.The first wall 320a on the X-direction side is spaced from, and on the X-direction side relative to, the first linking sections 240a of the plurality of connections 200. The first wall 320a on the X'-direction side is spaced from, and on the X'-direction side relative to, the first linking sections 240a of the plurality of connections 200.

[0046] The first sheath 300a can further comprise at least one first connecting section 330a. The at least one first connecting section 330a can be formed by cutting out a portion of the first sheath body 310a and bending that portion to the outside (e.g., to the X, X', or Z'-direction side) of the first sheath body 310a. Alternatively, the at least one first connecting section 330a can extend from the end on the Y-direction side of the first sheath body 310a and be folded in the Y' direction. It should be noted that the at least one first connecting section 330a, which is in the Fig. As shown in Figures 1A to 6B, the first connecting section 330a comprises a first connecting section 330a on the X-direction side and a first connecting section 330a on the X'-direction side. The first connecting section 330a on the X-direction side extends from the end on the Y-direction side of the wall on the X-direction side of the first shell body 310a and is folded over towards the X- and Y'-direction sides. The first connecting section 330a on the X'-side extends from the end on the Y-direction side of the wall on the X'-direction side of the first shell body 310a and is folded over towards the X' and Y'-direction sides. The first connecting section 330a on the X-direction side and the first connecting section 330a on the X'-direction side are elastically deformable in directions approaching each other in the X-X' direction. It should be noted that at least one of the first connecting section 330a can be omitted.

[0048] The connector FC further comprises a second connector part FC2 (a primary connector) and a support device. The support device comprises the elastically deformable sections 230 of the plurality of terminals 200. The second connector part FC2 is spaced apart from, and arranged on the Z-direction side relative to, the first connector part FC1. The second connector part FC2 is configured such that when the elastically deformable sections 230 of the plurality of terminals 200 deform elastically in the direction encompassing the component of the at least one direction, the elastic deformation causes the second connector part FC2 to displace relative to the first connector part FC1 in the direction encompassing the component of the at least one direction from a first predetermined normal position of the second connector part FC2 with respect to the first connector part FC1.The elastically deformable section 230 is thus elastically deformable and therefore acts as the support device.

[0067] The rear wall of the second housing body 410 can be provided with a mounting base 417 extending from the rear wall in the Y direction. The mounting base 417 may or may not abut the second connecting sections 240b (if provided) of the plurality of connections 200 from the Y'-direction side. The mounting base 417 faces the top plate 414 with a first gap 418 between them (see Fig. 5A). The first gap 418 extends in the Y-Y' direction and opens in the Y, X, and X' directions within the second casing body 410. The first gap 418 has a dimension in the Z-Z' direction that is essentially the same as the sum of a dimension in the Z-Z' direction of the plate 130b of the second body 100b and a dimension in the Z-Z' direction of a section on the Y'-direction side of the wall on the Z-direction side of the second casing body 310b, which is located on the plate 130b. The first gap 418 snugly and securely receives the plate 130b and the section on the Y'-direction side of the wall on the Z-direction side of the second casing body 310b. The mounting base 417 faces the side wall 415 with a second gap in between and faces the side wall 416 with a third gap in between (see Fig. 5G). The second gap accommodates a section on the Y'-direction side of the side wall 140b on the X'-direction side of the second body 100b and a section on the Y'-direction side of the wall on the X'-direction side of the second sheath body 310b thereon. The third gap accommodates a section on the Y'-direction side of the side wall 140b on the X'-direction side of the second body 100b and a section on the Y'-direction side of the wall on the X'-direction side of the second sheath body 310b thereon. It should be noted that the support base 417 can be omitted.

[0068] A first locking hole 460 can be provided in a section on the X-direction side of the ceiling panel 411 and the side wall 412, and a second locking hole 460 can be provided in a section on the X'-direction side of the ceiling panel 411 and the side wall 413. The first locking hole 460 and the second locking hole 460 extend in the Z-Z' direction and open in the Z' direction. It should be noted that the first locking hole 460 and the second locking hole 460 can be omitted.

[0069] The side walls 415 and 416 can be provided with a first guideable section 420 and a second guideable section 420, respectively. The first and second guideable sections 420 are recesses or holes provided in the side walls 415 and 416, respectively, and open in the X and X' directions. The first and second guideable sections 420 can also open in the Y' direction. It should be noted that the first guideable section 420 and the second guideable section 420 can be omitted.

[0070] The ceiling panel 414 can be provided with a shaft 430. The shaft 430 can be a cylinder extending from the ceiling panel 414 in the Z direction and having a shaft hole in a central section thereof. Alternatively, the shaft 430 can be a shaft hole in the ceiling panel 414. The ceiling panel 414 is provided with a domed locking projection 450 in a section on the X-direction side relative to the shaft 430 and with a domed locking projection 450 in a section on the X'-direction side relative to the shaft 430.

[0071] A side surface on the X-direction side of the side wall 412 can be provided with a guide groove on the X-direction side extending in the Y-Y' direction, and a side surface on the X'-direction side of the side wall 413 can be provided with a guide groove on the X'-direction side extending in the Y-Y' direction (see Fig. 4A to 6B). In this case, the second connecting section 330b is arranged on the X-direction side of the second shell 300b relative to the side wall 412 of the second housing body 410, and a distal section of the second connecting section 330b is guided on the X-direction side such that it moves in the Y-Y' direction in the guide groove on the X-direction side. The second connecting section 330b on the X'-direction side of the second shell 300b is arranged on the X'-direction side relative to the side wall 413 of the second housing body 410, and a distal section of the second connecting section 330b on the X'-direction side is guided such that it moves in the Y-Y' direction in the guide groove on the X-direction side.

[0072] The rear section of the second housing body 410 can be integrated into the second body 100b.

[0073] The second connector part FC2 further comprises a rotary lever 600. The rotary lever 600 has a lever body 610 and a screw or pin 620. The lever body 610 may include a disc 610a and a handle 610b extending from the disc 610a. A central section of the disc 610a is provided with a shaft hole 611. When the shaft 430 of the second housing 400 is formed by the cylinder described above, the shaft 430 is received in the shaft hole 611, and the screw or pin 620 is firmly received in the shaft hole of the shaft 430. In this case, the lever body 610 is positioned around the shaft 430 at the rear section of the second housing 400 in an unlocked position (see Fig. 2D) and a locked position (see Fig. 2C) rotatable.

[0074] If, instead of the shaft 430 of the second housing 400, the shaft hole in the top plate 414 of the second housing 400 is provided, the shaft hole of the second housing 400 is connected to the shaft hole 611 of the lever body 610, and the screw or pin 620 is firmly held in the shaft 430 and the shaft hole of the second housing 400. In this case, the lever body 610 is rotatable about the screw or pin 620 on the rear section of the second housing 400 between the unlocked position and the locked position.

[0075] In both cases, a rotation axis P1 (see Fig. 2D) of the rotary lever 600 the central axis of the screw or pin 620 and extends in the Z-Z' direction. In other words, the axial direction of the rotation axis P1 of the rotary lever 600 corresponds to the Z-Z' direction.

[0076] Fig. 2D represents a first state in which the lever body 610 is in the unlocked position (this state can simply be referred to as an “unlocked state”), and the handle 610b of the lever body 610 points in the X' direction. Fig. 2C represents a second state in which the lever body 610 is in the locked position (this state can simply be referred to as a "locked state"), and the handle 610b of the lever body 610 points in the X direction. Alternatively, the handle 610b of the lever body 610 may point in the X direction in the unlocked state, and the handle 610b of the lever body 610 may point in the X' direction in the locked state.

[0077] On a surface on the Z'-direction side of the disk of the lever body 610 (in Fig. 2C, Fig. 2D and Fig. 6B On a surface on the Z'-direction side of the disk 610a), a locking groove 613 is provided, which has a general arc shape and surrounds the shaft hole 611. The locking groove 613 is recessed in the Z direction and opens in the Z' direction (see Fig. 5B, Fig. 5C and Fig. 6B). In the unlocked state, the locking groove 613 has a generally arcuate shape that projects towards the X or X' direction side. The locking groove 613 is described below.

[0078] A locking recess 614 is provided on a surface on the Z'-direction side of a distal section of the handle 610b of the lever body 610. In the locked state, the locking projection 450 on the X-direction side of the second housing 400 fits into the locking recess 614 to temporarily lock the lever body 610. In the unlocked state, the locking projection 450 on the X'-direction side of the second housing 400 fits into the locking recess 614 to temporarily lock the lever body 610.

[0079] The lever body 610 can be formed by the disc 610a or the handle 610b. In the former case, the locking groove 613 and the locking recess 614 can be provided in the surface on the Z'-direction side of the disc 610a. In the latter case, the locking groove 613 and the locking recess 614 can be provided in a surface on the Z'-direction side of the handle 610b.

[0080] At a boundary between the ceiling panel 411 and the ceiling 414A, two stops 440 projecting towards the Z-direction side can be provided. The two stops 440 comprise a first stop 440 on the X-direction side and a second stop 440 on the X'-direction side. In the locked state, the first stop 440 on the Y-direction side is located relative to the handle 610b of the lever body 610 and rests against the handle 610b from the Y-direction side. In the unlocked state, the second stop 440 is located relative to the handle 610b of the lever body 610 on the Y-direction side and rests against the handle 610b from the Y-direction side. Thus, the two stops 440 define the rotation range of the rotary lever 600. The two stops 440 can be omitted.

[0081] The second housing 400 can be omitted. In this case, it is not the second housing 400, but the second body 100b that is provided with the shaft 430 or the shaft hole, and the rotary lever 600 is designed as described above, except that it is rotatably mounted on the second body 100b.

[0082] The FC connector can further comprise a second holder 500b. The second holder 500b is formed by an insulating resin or the like. The second holder 500b comprises a holder body 510b, a first locking piece 520b, and a second locking piece 520b. The holder body 510b extends in the X-X' direction. The first locking piece 520b and the second locking piece 520b extend from the holder body 510b in the Z direction and are spaced apart from each other in the X-X' direction. The first locking piece 520b and the second locking piece 520b are received from the Z' direction side into the first locking hole 460 and the second locking hole 460 of the second housing 400 respectively, and distal sections of the first and second locking pieces 520b are provided with respective lugs which lock into the first and second locking hole 460 respectively.In this locked state, a surface on the Y-direction side of the holder body 510b abuts a surface on the Y-direction side of the first locking hole 460 and a surface on the Y-direction side of the second locking hole 460 of the second housing 400, and a surface on the Y'-direction side of the holder body 510b abuts a surface on the Y-direction side of a section of the second body 100b that links the main section 110b of the second body and the second partitions 120b.Also in the locked position, the retaining body 510b rests against the second sheath body 310b of the second sheath 300b from the Z'-direction side, which is received in the second housing body 410 of the second housing 400, or alternatively, the retaining body 510b faces the second sheath body 310b of the second sheath 300b from the Z'-direction side, which is received in the second housing body 410 of the second housing 400, such that the retaining body 510b is located near the second sheath body 310b with a gap between them. The second retaining body 500b can thus serve to fasten the second sheath body 310b to the second housing body 410. It should be noted that both the second retaining body 500b and the second housing 400 can be omitted. Even if the second housing 400 is provided, the second holder 500b can be omitted.

[0083] The FC connector can further comprise a first housing 700. The first housing 700 is formed by an insulating material (e.g., an insulating resin or the like). The first housing 700 comprises a first housing body 710, which is generally U-shaped in a sectional view along the X-X' and Y-Y' directions. The first housing body 710 can comprise a first section 711, a second section 712, and a third section 713. The first section 711 is a wall on the Y'-direction side of the first housing body 710. The second section 712 is a wall on the X-direction side of the first housing body 710 and extends from an end on the X-direction side of the first section 711 in the Y direction. A side surface on the X-direction side of the second section 712 can be provided with a housing groove 712a (third housing groove) extending in the Y-Y' direction. The housing groove 712a opens in the Y and X directions.The third section 713 is a wall on the X'-direction side of the first housing body 710, extending from an end on the X'-direction side of the first section 711 in the Y direction. A side face on the X'-direction side of the third section 713 may be provided with a housing groove 713a (third housing groove) extending in the Y-Y' direction. The housing groove 713a opens in both the Y and X' directions. The housing groove 712a and the housing groove 713a may be omitted.

[0084] The first housing 700 further comprises a mounting section 720. The mounting section 720 is provided on a section on the Z'-direction side of the first housing body 710 and holds the first connector part FC1.

[0085] For example, in a sectional view along the Z-Z' and X-X' directions, the mounting section 720 has a general U-shape (see Fig. 2B and 4A to 6B) or a general ring shape (a polygonal ring shape, such as a general square ring shape, or a general circular ring shape (not shown)), and extends in the Y-Y' direction. The support section 720 has, in cross-section along the Z-Z' and X-X' directions, an internal shape and size that correspond in cross-section along the Z-Z' and X-X' directions to an external shape and size of the first sheath body 310a of the first sheath 300a. The support section 720 securely receives the first sheath body 310a, at least partially, from the Y-direction side. It should be noted that if the first sheath 300a is omitted, the support section 720 securely receives the first body 100a, at least partially, from the Y-direction side.

[0086] The mounting section 720 comprises a bottom section 721 on the Z'-direction side, a side wall 722 on the X-direction side, and a side wall 723 on the X'-direction side. The mounting section 720 comprises a distal section and a rear section. The distal section of the mounting section 720 is formed by respective sections on the Y-direction side of the bottom section 721, the side wall 722, and the side wall 723, and is located relative to the first housing body 710 on the Y-direction side. The rear section of the mounting section 720 is formed by respective sections on the Y'-direction side of the bottom section 721, the side wall 722, and the side wall 723, and is located inside the first housing body 710.If the support section 720 has a general U-shape in the cross-sectional view described above, the at least one first wall 320a (if provided) of the first sheath 300a extends between the side wall 722 and the side wall 723 of the support section 720 to be located on the Z-direction side relative to the support section 720. If the support section 720 has a general ring shape in the cross-sectional view described above, the support section 720 includes a ceiling section on the Z-direction side, which is provided with at least one slot extending through the ceiling section in the Z-Z' direction and opening in the Y direction, and the at least one first wall 320a (if provided) of the first sheath 300a extends through the at least one slot to be located on the Z-direction side relative to the support section 720.

[0087] The mounting section 720 may further comprise a mounting base 724 extending from the first section 711 of the first housing 700 in the Y-direction. The mounting base 724 may or may not abut the first connecting sections 240a (if provided) of the plurality of terminals 200 from the Y'-direction side. The mounting base 724 faces the bottom section 721 with a first gap 725 between them (see Fig. 5A). The first gap 725 extends in the Y-Y' direction and opens in the Y, X, and X' directions within the support section 720. The first gap 725 has a dimension in the Z-Z' direction that is essentially the same as the sum of a dimension in the Z-Z' direction of the plate 130a of the first body 100a and a dimension in the Z-Z' direction of a section on the Y'-direction side of the wall on the Z'-direction side of the first sheath body 310a, which is located on the plate 130a. The first gap 725 snugly and securely receives the plate 130a and the section on the Y'-direction side of the wall on the Z'-direction side of the first sheath body 310a. The mounting base 724 faces the side wall 722 with a second gap in between and faces the side wall 723 with a third gap in between (see Fig. 2F). The second gap accommodates a section on the Y'-direction side of the side wall 140a on the X'-direction side of the first body 100a and a section on the Y'-direction side of the wall on the X'-direction side of the first shell body 310a. The third gap accommodates a section on the Y'-direction side of the side wall 140a on the X'-direction side of the first body 100a and a section on the Y'-direction side of the wall on the X'-direction side of the first shell body 310a thereon. It should be noted that the support base 724 can be omitted.

In this case, the first connecting section 330a is arranged on the X-direction side of the first sheath 300a on the X-direction side relative to the side wall 722 of the support section 720, and a distal section of the first connecting section 330a on the X-direction side is guided such that it moves in the Y-Y' direction in the guide groove on the X-direction side. The first connecting section 330a on the X'-direction side of the first sheath 300a is arranged on the X'-direction side relative to the side wall 723 of the support section 720 and a distal section of the first connecting section 330a on the X'-direction side is guideable such that it moves in the Y-Y' direction in the guide groove on the X-direction side.

[0090] The first housing 700 can further comprise at least one guide 730. The at least one guide 730 movably guides the second connector part FC2 in the direction encompassing the component in at least one direction. The at least one guide 730 can comprise a first guide 730 on the X-direction side and a second guide 730 on the X'-direction side.

[0091] If the first guideable section 420 and the second guideable section 420 of the second housing 400 are provided, the first guide 730 is a projection extending from the second section 712 of the first housing body 710 to the X'-direction side, and is received from the X'-direction side into the first guideable section 420 to be movable in the direction encompassing at least one direction, and the second guide 730 is a projection extending from the third section 713 of the first housing body 710 to the X'-direction side, and is received from the X'-direction side into the second guideable section 420 to be movable in the direction encompassing at least one direction (see Fig. 5B and Fig. 5G). Thus, the first guide 730 and the second guide 730 movably guide the second housing 400 (i.e., the second connector part FC2) in the direction encompassing the component in at least one direction. If the first guide 730 and the second guide 730 are movable in the first guideable section 420 and the second guideable section 420, respectively, in a direction encompassing a component in the Z-Z' direction, the first guide 730 has a dimension in the Z-Z' direction that is smaller than a dimension in the Z-Z' direction of the first guideable section 420, and the second guide 730 has a dimension in the Z-Z' direction that is smaller than a dimension in the Z-Z' direction of the second guideable section 420.A linear distance in the Z-Z' direction between the surface on the Z-direction side of the first guide 730 and the surface on the Z'-direction side of the first guideable section 420, and a linear distance in the Z-Z' direction between the surface on the Z-direction side of the second guide 730 and the surface on the Z'-direction side of the second guideable section 420, can each be set to define a range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Z-direction, or they can each be greater than the range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Z-direction.A linear distance in the Z-Z' direction between the surface on the Z'-direction side of the first guide 730 and the surface on the Z-direction side of the first guideable section 420, and a linear distance in the Z-Z' direction between the surface on the Z'-direction side of the second guide 730 and the surface on the Z-direction side of the second guideable section 420, can each be set to define a range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Z' direction, or they can each be greater than the range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Z' direction.

[0092] If the first guide 730 and the second guide 730 are movable in the first guideable section 420 and the second guideable section 420 respectively in a direction encompassing a component in the X-X' direction, the first guide 730 has a dimension in the X-X' direction that is smaller than a dimension in the X-X' direction of the first guideable section 420 and the second guide 730 has a dimension in the X-X' direction that is smaller than a dimension in the X-X' direction of the second guideable section 420.A linear distance in the X-X' direction between the surface on the X'-direction side of the first guide 730 and the surface on the X-direction side of the first guideable section 420, and a linear distance in the X-X' direction between the surface on the X-direction side of the second guide 730 and the surface on the X'-direction side of the second guideable section 420, can each be set to define a range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the X-X' direction, or they can each be greater than the range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the XX direction.

[0093] If the first guide 730 and the second guide 730 are movable in the first guideable section 420 and the second guideable section 420 respectively in a direction encompassing a component in the Y-Y' direction, the first guide 730 has a dimension in the Y-Y' direction that is smaller than a dimension in the Y-Y' direction of the first guideable section 420, and the second guide 730 has a dimension in the Y-Y' direction that is smaller than a dimension in the Y-Y' direction of the second guideable section 420.A linear distance in the Y-Y' direction between the surface on the Y-direction side of the first guide 730 and the surface on the Y'-direction side of the first guideable section 420, and a linear distance in the Y-Y' direction between the surface on the Y-direction side of the second guide 730 and the surface on the Y'-direction side of the second guideable section 420, can each be set to define a range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Y-direction, or they can each be greater than the range of motion in which the second connector part FC2 is movable relative to the first connector part FC1 in a direction encompassing a component of the Y-direction.

[0133] If at least one third connecting section 930 is provided on the second shielding 900 (see Fig. 4A to 6B), the at least one third connecting section 930 can be at least one spring-like element extending from the second shielding body 910 in the Y' direction and can be in elastic contact with the first shielding body 810 of the first shielding 800 from the X or X' direction side. The at least one third connecting section 930 can be curved such that it has a general V-shape, either completely or partially (e.g., a distal section on the Y' direction side), projecting towards the first shielding body 810 of the first shielding 800, or it can be curved such that it has a general arc shape, either completely or partially (e.g., a distal section on the Y' direction side), projecting towards the first shielding body 810 of the first shielding 800.

[0134] The at least one third connecting section 930 can comprise two third connecting sections 930, and the two third connecting sections 930 can comprise a third connecting section 930 on the X-direction side (primary third connecting section 930) and a third connecting section 930 on the X'-direction side (secondary third connecting section 930).In this case, the third connecting section 930 on the X-direction side can extend from the end on the X-direction side of the second shielding body 910 in the Y' direction, be received from the Y-direction side in the housing groove 712a of the second section 712 and be in elastic contact from the X'-direction side with the second shielding section 812 of the first shielding body 810; and the third connecting section 930 on the X'-direction side can extend from the end on the X'-direction side of the second shielding body 910 in the Y' direction, be received from the Y-direction side in the housing groove 713a of the third section 713 and be in elastic contact from the X-direction side with the third shielding section 813 of the first shielding body 810. The third connecting section 930 on the X-direction side can include two locking projections that extend in the Z-direction andThe third connecting section 930 may project in the Z' direction, but this is not required. In a state where the third connecting section 930 is received in the housing groove 712a on the X-direction side, the two locking projections of the third connecting section 930 can be locked against the wall on the Z-direction side and against the wall on the Z'-direction side of the housing groove 712a, respectively. The third connecting section 930 on the X'-direction side may have two locking projections that project in the Z-direction and Z'-direction, respectively, but this is not required. In a state in which the third connecting section 930 is received in the housing groove 713a on the X'-direction side, the two locking projections of the third connecting section 930 can be locked to the wall on the Z-direction side and to the wall on the Z'-direction side of the housing groove 713a, respectively.

[0135] The second shielding section 812 of the first shielding body 810 can be provided with a projection 812a that projects towards the X'-direction side (see Fig. 6A). The projection 812a is located in the housing groove 712a. The distal section of the third connecting section 930 on the X-direction side can be configured such that, from the beginning of its insertion into the housing groove 712a until it is completely received in the housing groove 712a (before it reaches the projection 812a of the second shielding section 812), it is not in contact with the second shielding section 812 due to an intermediate gap, but that, from the X'-direction side, it can be in elastic contact with the projection 812a of the second shielding section 812 when it is completely received in the housing groove 712a (in a state where it has reached the projection 812a of the second shielding section 812).Alternatively, the distal section of the third connecting section 930 on the X-direction side can be configured such that, from the beginning of its insertion into the housing groove 712a until it is completely received in the housing groove 712a, it is in elastic contact with the second shielding section 812, and that, from the X'-direction side, it can be in elastic contact with the projection 812a of the second shielding section 812 when it is completely received in the housing groove 712a (in a state where it has reached the projection 812a of the second shielding section 812). In either case, the third connecting section 930 on the X-direction side provides increased contact pressure against the second shielding section 812.In a state where the third connecting section 930 on the X-direction side has reached the projection 812a of the second shielding section 812, the third connecting section 930 on the X-direction side can be locked in the housing groove 712a in the manner described above. The third shielding section 813 of the first shielding body 810 can be provided with a projection 813a that projects towards the X-direction side (see . Fig. 6A). The projection 813a is located in the housing groove 713a. The distal section of the third connecting section 930 on the X'-direction side can be configured such that, from the beginning of its insertion into the housing groove 713a until it is completely received in the housing groove 713a (before it reaches the projection 813a of the third shielding section 813), it is not in contact with the third shielding section 813 of the first shielding body 810 due to an intermediate gap, but that, from the X-direction side, it can be in elastic contact with the projection 813a of the third shielding section 813 when it is completely received in the housing groove 713a (in a state where it has reached the projection 813a of the third shielding section 813).Alternatively, the distal portion of the third connecting section 930 on the X'-direction side can be configured such that, from the beginning of its insertion into the housing groove 712a until it is fully received in the housing groove 713a, it is in elastic contact with the third shielding section 813, and that, from the X-direction side, it can be in elastic contact with the projection 813a of the third shielding section 813 when it is fully received in the housing groove 713a (in a state where it has reached the projection 813a of the third shielding section 813). In either case, the third connecting section 930 on the X'-direction side provides increased contact pressure against the third shielding section 813.In a state where the third connecting section 930 on the X'-direction side has reached the projection 813a of the third shielding section 813, the third connecting section 930 on the X'-direction side can be locked in the housing groove 713a in the manner described above. It should be noted that the projection 812a and the projection 813a can be omitted.

[0136] The third connecting section 930 on the X-direction side comprises a curved section that is bent at approximately 90 degrees relative to the second shielding body 910. The curved section may be provided with a window 940 extending through the curved section. The third connecting section 930 on the X'-direction side comprises a curved section that is bent at approximately 90 degrees relative to the second shielding body 910. The curved section may be provided with a window 940 extending through the curved section. Respective end surfaces on the Y'-direction side of the windows 940 act as pressure surfaces which are pressed by a device from the Y-direction side when the third connecting section 930 on the X-direction side is inserted into the housing groove 712a and the third connecting section 930 on the X'-direction side is inserted into the housing groove 713a.Windows 940 can be omitted.

[0137] Alternatively, the third connecting section 930 can extend from the end on the X-direction side of the second shielding body 910 in the Y' direction and be in elastic contact with the second shielding section 812 of the first shielding body 810 from the X' direction side, and the third connecting section 930 can extend from the end on the X' direction side of the second shielding body 910 in the Y' direction and be in elastic contact with the third shielding section 813 of the first shielding body 810 from the X-direction side.

[0138] If the at least one third connecting section 930 is provided on the first shield 800 (not shown), the at least one third connecting section 930 can be at least one spring element extending from the first shield body 810 to the second shield body 910 and being in elastic contact with the second shield body 910. For example, the at least one third connecting section 930 can extend through at least one third through-hole, at least one third recess, or the like, provided in the first housing body 710 of the first housing 700 to elastically contact the second shield body 910.The at least one third connecting section 930 can extend from the end on the Y-direction side of the second shielding section 812 of the first shielding body 810 and be bent in the X' direction and be in elastic contact with the second shielding body 910 from the Y-direction side. Alternatively, the at least one third connecting section 930 can extend from the end on the Y-direction side of the third shielding section 813 of the first shielding body 810, be bent in the X-direction, and be in elastic contact with the second shielding body 910 from the Y-direction side.The at least one third connecting section 930 may be bent in such a way that it has a general V-shape, either completely or partially, projecting towards the second shielding body 910, or alternatively be curved in such a way that it has a general arc shape, either completely or partially, projecting towards the second shielding body 910.

[0139] It should be noted that the at least one third connecting section 930 can be omitted. In this case, the first shield 800 and the second shield 900 can be electrically connected to each other via the first sheath 300a and / or the second sheath 300b by being electrically connected to the first sheath 300a and / or the second sheath 300b in the manner described above. Alternatively, the first shield 800 and the second shield 900 can be electrically connected to each other via a cable, another connection, or the like. Another alternative is that the first shield 800 and the second shield 900 can be electrically connected to each other by bringing the first shielding body 810 of the first shield 800 into contact with the second shielding body 910 of the second shield 900.

[0140] The following describes non-restrictive methods for manufacturing the FC connector described above. First, the initial body 100a and the plurality of terminals 200 are prepared.

[0141] The first contact sections 210a of the plurality of terminals 200 are inserted from the Y'-direction side into the respective mounting holes 111a and / or the respective mounting grooves 112a of the first body 100a, and the first retainable sections 220a of the plurality of terminals 200 are inserted into and retained by the respective mounting holes 111a and / or the respective mounting grooves 112a of the first body 100a. The first retainable sections 220a of the plurality of terminals 200 are thus held at intervals in the X-X' direction within the first body 100a.At this point, the first contact sections 210a of the plurality of terminals 200 project at least partially in the Y-direction from the respective mounting holes 111a or the respective mounting grooves 112a of the first body 100a, or alternatively are arranged in the respective connecting holes (if provided) of the first body 100a and are at least partially exposed in the Y-direction from the respective connecting holes or project at least partially from them.

[0142] If the plurality of connections 200 includes the respective first linking sections 240a and the first body 100a includes the plurality of first partitions 120a, if the first holdable sections 220a of the plurality of connections 200 are held in the first body 100a, the first linking sections 240a of the plurality of connections 200 are inserted between each pair of the plurality of first partitions 120a of the first body 100a.

[0143] After the multitude of connections 200 have been installed on the first body 100a in this way, the first sheath 300a is prepared.

[0144] The first body 100a is inserted into the first sheath body 310a of the first sheath 300a from the Y'-direction side and held by it. Consequently, the first contact sections 210a and the first retainable sections 220a of the plurality of terminals 200 are at least partially located together with the first body 100a in the first sheath body 310a. Simultaneously, the section of the first sheath body 310a located relative to the first body 100a on the Y-direction side defines the first connection space. If the first contact sections 210a of the plurality of terminals 200 project at least partially from the first body 100a, the first contact sections 210a are at least partially located in the first connection space of the first sheath body 310a.

[0145] If the first sheath 300a comprises the first two walls 320a, the first linking sections 240a of the plurality of connections 200 are arranged between the two first walls 320a when the first body 100a is inserted into the first sheath body 310a of the first sheath 300a. The first body 100a can be held in the first sheath body 310a of the first sheath 300a before the plurality of connections 200 are installed on the first body 100a as described above.

[0146] This is how the first connector part FC1 is assembled.

[0147] The second body 100b is prepared. The second contact sections 210b of the plurality of terminals 200 are inserted from the Y'-direction side into the respective mounting holes 111b and / or the respective mounting grooves 112b of the second body 100b, and the second retainable sections 220b of the plurality of terminals 200 are inserted into and retained by the respective mounting holes 111b and / or the respective mounting grooves 112b of the second body 100b. The second retainable sections 220b of the plurality of terminals 200 are thus held at intervals in the X-X' direction in the second body 100b.At this point, the second contact sections 210b of the plurality of terminals 200 project at least partially in the Y-direction from the respective mounting holes 111b or the alternative mounting grooves 112b of the second body 100b, or are alternatively arranged in the respective connecting holes (if provided) of the second body 100b and are at least partially exposed in the Y-direction from the respective connecting holes or project at least partially from them.

[0148] If the plurality of connections 200 includes the second linking sections 240b and the second body 100b includes the plurality of second partitions 120b, if the second holdable sections 220b of the plurality of connections 200 are held in the second body 100b, the second linking sections 240b of the plurality of connections 200 are inserted between each pair of the plurality of second partitions 120b of the second body 100b.

[0149] After the multitude of connections 200 have been installed on the second body 100b as described above, the second sheath 300b is prepared.

[0150] The second body 100b is inserted into the second sheath body 310b of the second sheath 300b from the Y-direction side and held by it. Consequently, the second contact sections 210b and the second retainable sections 220b of the plurality of terminals 200 are at least partially located together with the second body 100b in the second sheath body 310b. Simultaneously, the section of the second sheath body 310b that is located relative to the second body 100b on the Y-direction side defines the second connection space. If the second contact sections 210b of the plurality of terminals 200 project at least partially from the second body 100b, the second contact sections 210b are at least partially located in the second connection space of the second sheath body 310b.

[0151] If the second sheath 300b comprises the two second walls 320b, the second connecting sections 240b of the plurality of connections 200 are arranged between the two second walls 320b when the second body 100b is inserted into the second sheath body 310b of the second sheath 300b. It should be noted that the second body 100b can be held in the second sheath body 310b of the second sheath 300b before the plurality of connections 200 is installed on the second body 100b as described above.

[0152] After the second body 100b has been held in the second shell body 310b of the second shell 300b, the second casing 400 is prepared. The second shell body 310b of the second shell 300b is inserted into the second casing body 410 of the second casing 400 from the Y-direction side and held by it.

[0153] When the second housing body 410 is provided with the mounting base 417, and when the second outer shell body 310b of the second outer shell 300b is inserted into the second housing body 410 of the second housing 400, and the mounting base 417 is brought into contact with the second connecting sections 240b (if provided) of the plurality of connections 200 from the Y'-direction side or arranged spaced apart from the second connecting sections 240b (if provided) of the plurality of connections 200, the plate 130b of the second body 100b and the section on the Y'-direction side of the wall on the Z-direction side of the second outer shell body 310b are inserted into the first gap 418 between the ceiling plate 414 and the mounting base 417 of the second housing body 410.The section on the Y'-direction side of the side wall 140b on the X-direction side of the second body 100b and the section on the Y'-direction side of the wall on the X-direction side of the second shell body 310b are inserted into the second gap between the side wall 415 and the mounting base 417 of the second housing body 410, and the section on the Y'-direction side of the side wall 140b on the X'-direction side of the second body 100b and the section on the Y'-direction side of the wall on the X'-direction side of the second shell body 310b are inserted into the third gap between the side wall 416 and the mounting base 417 of the second housing body 410.

[0154] If at least one second wall 320b of the second shell 300b is provided, when the second shell body 310b of the second shell 300b is inserted into the second housing body 410 of the second housing 400, the at least one second wall 320b of the second shell 300b passes between the side wall 412 and the side wall 413 and between the side wall 415 and the side wall 416 of the second housing body 410 with the general U-shape described above and is arranged on the Z'-direction side relative to the second housing body 410, or it passes through the at least one slot of the bottom section of the second housing body 410 with the general ring shape described above and is arranged on the Z'-direction side relative to the second housing body 410. If the at least one second wall 320b is not provided, the above step is omitted.

[0155] If the second holder 500b is provided, the second holder 500b is prepared. The first locking piece 520b and the second locking piece 520b of the second holder 500b are inserted from the Z'-direction side into the first locking hole 460 and the second locking hole 460 of the second housing 400, respectively, and the lugs on the distal sections of the first and second locking pieces 520b are locked into the first locking hole 460 and the second locking hole 460, respectively. At this point, the second holder 500b secures the second jacket body 310b of the second jacket 300b to the second housing body 410 of the second housing 400.

[0156] This is how the second connector part FC2 is assembled. If the second housing 400 is omitted, the steps relating to the second housing 400 are omitted from the steps for assembling the second connector part FC2. If the second holder 500b is omitted, the steps relating to the second holder 500b are also omitted from the steps for assembling the second connector part FC2.

[0157] If the rotary lever 600 is provided, the shaft 430 of the second housing 400 is inserted into the shaft hole 611 of the lever body 610 of the rotary lever 600. Then, the screw or pin 620 of the rotary lever 600 is inserted into the shaft hole of the shaft 430 and secured to it. Alternatively, the shaft hole 611 of the lever body 610 of the rotary lever 600 is arranged so that it is connected to the shaft hole of the second housing 400. Then, the screw or pin 620 of the rotary lever 600 is inserted into the shaft hole of the shaft 430 and the shaft hole of the second housing 400 and secured to it.

[0168] If the second shield 900 is provided with the two first connecting sections 920a, if the second shield 900 is brought relatively closer to the first housing 700 in the Y-Y' direction, the first connecting section 920a on the X-direction side is brought into elastic contact with the first wall 320a on the X-direction side (if provided) of the first sheath 300a from the X-direction side, or alternatively, is received in the first housing groove on the X-direction side of the mounting section 720 in order to elastically contact the first sheath body 310a of the first sheath 300a from the X-direction side;The first connecting section 920a on the X'-direction side is brought into elastic contact with the first wall 320a on the X'-direction side (if provided) of the first sheath 300a, or alternatively, it is inserted into the first housing groove on the X'-direction side of the mounting section 720 to elastically contact the first sheath body 310a of the first sheath 300a from the X'-direction side. Thus, the second shield 900 and the first sheath 300a are electrically connected. If the two first connecting sections 920a constitute a single first connecting section 920a, the above steps should apply to one of the two first connecting sections 920a for the single first connecting section 920a. If the first connecting section 920a / the first connecting sections 920a is / are omitted, the steps relating to the first connecting section 920a are omitted.

[0169] If the second shield 900 is provided with the two second connecting sections 920b, if the second shield 900 is brought relatively closer to the first housing 700 in the Y-Y' direction, the second connecting section 920b on the X-direction side is brought into elastic contact with the second wall 320b on the X-direction side (if provided) of the second jacket 300b from the X-direction side, or alternatively, is received in the second housing groove on the X-direction side of the second jacket body 310b in order to elastically contact the second jacket body 310b of the second jacket 300b from the X-direction side; and the second connecting section 920b on the X'-direction side is brought into elastic contact with the second wall 320b on the X'-direction side (if provided) of the second shell 300b from the X'-direction side, or alternatively received in the second housing groove on the X'-direction side of the second shell body 310b,to elastically contact the second sheath body 310b of the second sheath 300b from the X'-direction side. Thus, the second shield 900 and the second sheath 300b are electrically connected. If the two second connecting sections 920b constitute a single second connecting section 920b, the steps above should apply to one of the two second connecting sections 920b for the single second connecting section 920b. If the second connecting section 920b / the second connecting sections 920b is / are omitted, the steps relating to the second connecting section 920b / the second connecting sections 920b are omitted.

[0170] When the second shield 900 is provided with the two third connecting sections 930, when the second shield 900 is brought relatively closer to the first housing 700 in the Y-Y' direction, the third connecting section 930 on the X-direction side is received from the Y-direction side into the housing groove 712a of the second section 712 of the first housing 700 in order to elastically contact the second shielding section 812 of the first shield 800 from the X'-direction side, and the third connecting section 930 on the X'-direction side is received from the Y-direction side into the housing groove 713a of the third section 713 of the first housing 700 in order to elastically contact the third shielding section 813 of the first shield 800 from the X-direction side.The third connecting section 930 on the X-direction side can be locked in the housing groove 712a when it is fully engaged in the housing groove 712a. The third connecting section 930 on the X'-direction side can be locked in the housing groove 713a when it is fully engaged in the housing groove 713a.

[0171] If the second shielding section 812 of the first shielding body 810 is provided with the projection 812a and the third shielding section 813 of the first shielding body 810 is provided with the projection 813a, the distal section of the third connecting section 930 on the X-direction side moves from the beginning of the insertion of the third connecting section 930 on the X-direction side into the housing groove 712a until the third connecting section 930 on the X-direction side is completely received in the housing groove 712a in the Y' direction, without contacting the second shielding section 812 of the first shielding body 810, or it slides on the second shielding section 812 in the Y' direction.When the third connecting section 930 is fully received in the housing groove 712a on the X-direction, the distal section of the third connecting section 930 on the X-direction side is in elastic contact with the projection 812a of the second shielding section 812 from the X'-direction side and can be locked in the housing groove 712a. From the beginning of the insertion of the third connecting section 930 on the X'-direction side into the housing groove 713a until the third connecting section 930 on the X'-direction side is completely received in the housing groove 713a, the distal section of the third connecting section 930 on the X'-direction side moves in the Y' direction without contacting the third shielding section 813 of the first shielding body 810, or slides on the third shielding section 813 in the Y' direction.When the third connecting section 930 on the X'-direction side is fully received in the housing groove 713a, the distal section of the third connecting section 930 on the X'-direction side is in elastic contact with the projection 813a of the third shielding section 813 from the X-direction side and can be locked in the housing groove 713a.

[0172] Thus, the second shield 900 is electrically connected to the first shield 800 in the manner described above. It should be noted that if the curved section of the third connecting section 930 is provided with the window 940 on the X-direction side, and the curved section of the third connecting section 930 is provided with the window 940 on the X'-direction side, the end faces of the windows 940 on the Y'-direction side can be pressed through the devices from the Y-direction side, and thereby the third connecting section 930 on the X-direction side can be inserted into the housing groove 712a from the Y-direction side, and the third connecting section 930 on the X'-direction side can be inserted into the housing groove 713a from the Y-direction side.

[0173] It should be noted that if the two third connecting sections 930 constitute a single third connecting section 930, the steps mentioned above for either of the two third connecting sections 930 should apply to the single third connecting section 930. If the third connecting section(s) 930 is / are omitted, the steps relating to the third connecting section(s) 930 are omitted.

[0174] If the second shield 900 is omitted, the steps relating to the second shield 900 are omitted.

The plurality of first electrodes 1 are surface electrodes provided at intervals in the X-X' direction on a surface on the Z-direction side of the first printed circuit board B1, or alternatively, through-hole electrodes provided at intervals in the X-X' direction in the first printed circuit board B1.

The plurality of first ground electrodes 2 are surface electrodes provided on the surface on the Z-direction side of the first printed circuit board B1 and connectable to ground, or alternatively, through-hole electrodes provided in the first printed circuit board B1 and connectable to ground. The plurality of first access holes 3 extends through the first printed circuit board B1 in the Z-Z' direction.The multitude of first earth electrodes 2 and / or the multitude of first intervention holes 3 can be omitted.

[0177] The first mating connector MC1 is mounted on the first circuit board B1 from the Z-direction side and can be detachably connected from the Y-direction side to the first connector part FC1 of the floating connector FC. The term "first connection state," as used here, refers to a state in which the first mating connector MC1 is connected to the first connector part FC1 of the connector FC described above in the Y-Y' direction.

[0178] The first mating connector MC1 comprises a first body 10. The first body 10 is formed by an insulating material (e.g., an insulating resin or the like). The first body 10 only needs to have a shape that is connectable to the first connector part FC1 of the connector FC described above in the Y-Y' direction.

[0179] The first body 10 can comprise a base 11 and a projection 12. The base 11 is generally a wall extending, for example, in the Z-Z' and X-X' directions. A plurality of retaining grooves 11a are provided in a wall face on the Y-direction side of the base 11 and at intervals in the X-X' direction. Additionally, a locking groove 11b can be provided at each end section on the X-direction side and at each end section on the X'-direction side of the base 11.

[0180] The projection 12 is formed by a polygonal prism (e.g. a square prism (see Fig. 9A to 9D), a hexagonal prism (not shown) or the like) or a cylinder (not shown). The projection 12 extends from a central section of the base 11 in the Y' direction. In the first connection state, the projection 12 is inserted into the first connection space of the first sheath body 310a of the first connector part FC1 of the connector FC and rests against the main section 110a of the first body 100a of the first connector part FC1. The projection 12 has, in cross-section along the Z-Z' and X-X' directions, an outer shape and size that correspond to an inner shape and size along the ZZ and X-X' directions of the first sheath body 310a.

[0181] The projection 12 is provided with a plurality of mounting holes 12a and a plurality of connecting holes 12b. The plurality of mounting holes 12a is arranged in the X-X' direction at the same intervals as the plurality of mounting grooves 11a. The plurality of mounting holes 12a opens in the Y direction. The plurality of connecting holes 12b is arranged in the X-X' direction at the same intervals as the plurality of mounting holes 12a, is located on the Y'-direction side relative to the plurality of mounting holes 12a, and is connected to it. The plurality of connecting holes 12b opens in the Y' direction.

[0182] The multiple connecting holes 12b can be omitted. In this case, the multiple mounting holes 12a extend through the projection 12 in the Y-Y' directions and open only in the Y direction, but also in the Y' direction.

[0183] The first body 10 may further have a tubular section 13. In a sectional view along the Z-Z' and X-X' directions, the tubular section 13 has a general ring shape (e.g., a polygonal ring shape, such as a general quadrilateral ring shape (see Fig. 8A to Fig. 10B) or a general circular ring shape (not shown)). The tubular section 13 extends from the base 11 in the Y-direction and surrounds the projection 12. The tubular section 13 and the projection 12 define a first insertion space with a general ring shape (e.g., a polygonal ring shape, such as a general quadrilateral ring shape (see Fig. 8A to Fig. 10B) or a generally circular ring shape (not shown)). If the connector FC is provided with the first housing 700, in the first connection state the distal portion of the retaining section 720 of the first housing 700 of the connector FC is inserted into the first insertion space in the Y-Y' direction. If the connector FC is not provided with the first housing 700, in the first connection state the distal portion of the first jacket body 310a of the first jacket 300a of the connector FC is inserted into the first insertion space in the Y-Y' direction. The tubular section 13 comprises a first side wall on the X-direction side, a second side wall on the X'-direction side of the tubular section 13, a top plate on the Z-direction side, and a bottom plate on the Z'-direction side.

[0184] The first and second side walls of the tubular section 13 can be provided with a first slot 13a and a second slot 13a, respectively. The first slot 13a extends through the first side wall of the tubular section 13 in the X-X' direction and extends in the Y-Y' direction. The second slot 13a extends through the second side wall of the tubular section 13 in the X-X' direction and extends in the Y-Y' direction. In the first connection state, the first connecting section 330a on the X-direction side and the first connecting section 330a on the X'-direction side of the first jacket 300a of the first connector part FC1 of the connector FC are received in the first slot 13a and the second slot 13a, respectively.It should be noted that if the first connecting section 330a on the X-direction side and the first connecting section 330a on the X'-direction side are omitted, the first slot 13a and the second slot 13a can also be omitted.

[0185] The upper plate of the tubular section 13 can be provided with a recess 13c (which will be described later). The recess 13c can be omitted.

[0186] The first mating connector MC1 also includes a support 14 (which will be described later). The support 14 can be omitted.

[0187] The base plate of the tubular section 13 can be provided with a plurality of engagement projections 15 projecting in the Z' direction. The plurality of engagement projections 15 are inserted into the respective first engagement holes 3 of the first circuit board B1. The base plate of the tubular section 13 can further be provided with a locking recess 13b. In the first connection state, the locking arm 750 of the first housing 700 is locked in the locking recess 13b. The engagement projection 15 and / or the locking recess 13b can be omitted.

[0188] The first mating connector MC1 further comprises at least one first terminal 20. This at least one first terminal 20 can be a single first terminal 20 or a plurality of first terminals 20. For the sake of simplicity, the at least one first terminal 20 is described as a plurality of first terminals 20. However, even in a case where a single first terminal 20 is provided, the first terminal 20 can be configured similarly to each of the first terminals 20.

[0189] Each of the first terminals 20 can, for example, be produced by the rolling process described above. In this case, a first surface on the X-direction side and a second surface on the X'-direction side of each terminal 200 are flat-rolled surfaces. Each terminal 200 can be produced not by the rolling process, but by another known terminal production method, such as a photolithography process or an inkjet process.

[0190] The plurality of first connections 20 comprises respective first contact sections 21, respective first retainable sections 22, and respective first conductor sections 23. The plurality of first connections 20 may further comprise respective first linking sections 24.

[0191] The first retainable sections 22 of the plurality of first connections 20 are generally L-shaped plates and are securely received from the Y-direction side in the respective retaining grooves 11a of the base 11 of the first body 10 and the respective retaining holes 12a of the projection 12. Thus, the first retainable sections 22 of the plurality of first connections 20 are held at intervals in the X-X' direction in the first body 10.

[0192] The first contact sections 21 of the plurality of first connections 20 can extend in the Y' direction from the corresponding first linking sections 24. Each of the first contact sections 21 can be formed by a plate (not shown), a rod (not shown), or a tube (not shown), or can have a forked shape comprising a first and a second contact arm 21a (see Fig. 2A, 2B, 3A, 3B, and 9A to 11B). The first contact sections 21 of the plurality of first terminals 20 project at least partially from the first body 10 or are at least partially exposed, such that they are visible from the Y' direction side.

[0193] When the first body 10 comprises the plurality of connection holes 12b, the first contact sections 21 of the plurality of first terminals 20 are arranged in the respective connection holes 12b from the Y-direction side and are at least partially exposed in the Y' direction from the respective connection holes 12b. In the first connection state, the first contact sections 210a of the plurality of terminals 200 of the first connector part FC1 of the connector FC, which project at least partially from the first body 100a, are received in the respective connection holes 12b of the first body 10 from the Y' direction side and are in contact with the respective first contact sections 21 of the plurality of first terminals 20.

[0194] If the first body 10 does not include the plurality of connection holes 12b, the first contact sections 21 of the plurality of first terminals 20 project at least partially in the Y' direction from their respective mounting holes 12a. In the first connection state, the first contact sections 210a of the plurality of terminals 200 of the first connector part FC1 of the connector FC, which project at least partially from the first body 100a, are in contact with the respective first contact sections 21 of the plurality of first terminals 20. Alternatively, in the first connection state, the first contact sections 21 of the plurality of first terminals 20 are received in the respective connection holes of the second body 100b of the first connector part FC1 of the connector FC and are in contact with the respective first contact sections 210a of the plurality of terminals 200 of the first connector part FC1.

[0195] The first linking sections 24 of the plurality of first connections 20 only need to link the first holdable sections 22 and the first contacting sections 21.

[0196] If the first contact section 210a of each terminal 200 of the first connector part FC1 of the connector FC is formed by a plate or rod inclined in the first inclined direction (see Fig. 3A, Fig. 3B, Fig. 11A and Fig. 11B), the first connecting section 24 of each first connection 20 may be bent or curved such that the first contacting arm 21a and the second contacting arm 21a of the first contacting section 21 of each first connection 20 can be elastically contacted with the first surface 211a and the second surface 212a of the corresponding first contacting section 210a from one side and the other side of a third oblique direction (substantially perpendicular to the first surface 211a and the second surface 212a, respectively), if the third oblique direction is substantially orthogonal to the first oblique direction.Alternatively, the first connecting section 24 of each first terminal 20 can be bent or curved such that the plate- or rod-shaped first contacting section 21 of each first terminal 20 can be contacted with the first surface 211a or the second surface 212a of the corresponding first contacting section 210a from one side or the other side of the third inclined direction.

[0197] If the first contact section 210a of each terminal 200 of the first connector part FC1 of the connector FC comprises the first and the second contact arm inclined in the first inclined direction (not shown), the first linking section 24 of each first terminal 20 may be bent or curved such that the first and second faces of the first contact section 21 of each first terminal 20 are inclined in the third inclined direction, and the first and second contact arms of the corresponding first contact section 210a are elastically contactable with the first and second faces of the first contact section 21 from one side and the other side of the first inclined direction (essentially perpendicular to the first and second faces of the first contact section 21).

[0198] The first linking sections 24 of the plurality of first connections 20 cannot be bent or curved, but extend straight from the corresponding first holdable sections 22 to the corresponding first contacting sections 21 (not shown).

[0199] The first interconnection sections 24 of the plurality of first connections 20 can be omitted. In this case, the first contact sections 21 of the plurality of first connections 20 can extend from the corresponding first retainable sections 22 in the Y' direction.

[0200] The first conductor sections 23 of the plurality of first terminals 20 can extend from the corresponding first retainable sections 22 in the Y-direction, be arranged relative to the first body 10 on the Y-direction side, and be connected to the respective first electrodes 1, which are surface electrodes of the first circuit board B1. Alternatively, the first conductor sections 23 of the plurality of first terminals 20 can extend from the corresponding first retainable sections 22 in the Z'-direction, be arranged relative to the first body 10 on the Z-direction side, and be connected to the respective first electrodes 1, which are through-hole electrodes of the first circuit board B1.

[0201] The first mating connector MC1 can further comprise a first sheath 30 with electrical conductivity. The first sheath 30 can be formed by an electrically conductive material (e.g., a metal plate or the like) or comprise an insulating material (e.g., an insulating resin or the like) and metal vapor-deposited onto an inner or outer surface of the insulating material. The first sheath 30 comprises a first sheath body 31. In a sectional view along the Z-Z' and X-X' directions, the first sheath body 31 has a general U-shape (not shown) or a general ring shape (a polygonal ring shape, such as a general square ring shape, or a general circular ring shape (not shown)). The first sheath body 31 extends in the Y-Y' direction.The first shell body 31 has an internal shape and size in cross-section along the Z-Z' and X-X' directions that correspond to an external shape and size of the first body 10 in cross-section along the Z-Z' and X-X' directions. The first body 10 is at least partially enclosed in the first shell body 31 from the Y-direction side. The first shell body 31 comprises an upper plate on the Z-direction side, a first side plate on the X-direction side, and a second side plate on the X'-direction side.

[0202] When the tubular section 13 is provided with the first slot 13a and the second slot 13a, the first side plate and the second side plate of the first jacket body 31 are exposed to the inside of the first jacket body 31 by the first slot 13a and the second slot 13a, respectively. In the first connection state, the first connecting section 330a on the X-direction side and the first connecting section 330a on the X'-direction side of the first jacket 300a of the first connector part FC1 of the connector FC are received in the first slot 13a and the second slot 13a, respectively, and are in elastic contact with the first side plate and the second side plate of the first jacket body 31, respectively. Thus, in the first connection state, the first jacket 30 is electrically connected to the first jacket 300a of the first connector part FC1 of the connector FC.If the tubular section 13 is omitted, in the first connection state the distal section of the first sheath body 310a of the first sheath 300a of connector FC is inserted into the first insertion space and is in contact with the first sheath body 31. Furthermore, in this way the first sheath 30 is electrically connected to the first sheath 300a of the first connector part FC1 of connector FC in the first connection state.

[0203] The upper plate of the first shell body 31 is provided with a cutout 31a or an opening to expose the abutment 14 towards the Z-direction side.

[0204] The first sheath 30 can further comprise a first cover 32. The first cover 32 is a plate that adjoins the end on the Y-direction side of the upper plate of the first sheath body 31 and covers the first body 10 from the Y-direction side. The first cover 32 can be omitted.

[0205] The first sheath 30 can further comprise a plurality of first legs 33 on the X-direction side and a plurality of second legs 33 on the X'-direction side. Each of the first legs 33 extends from an end on the Z'-direction side of the first side plate of the first sheath body 31 in the Z' direction and is connected to a corresponding first ground electrode 2, which is a through-hole electrode of the first circuit board B1, or alternatively extends from the end on the Z'-direction side of the first side plate of the first sheath body 31 in the X direction and is connected to a corresponding first ground electrode 2, which is a surface electrode of the first circuit board B1.Each of the second legs 33 extends from an end on the Z'-direction side of the second side plate of the first sheath body 31 in the Z' direction and is connected to a corresponding first ground electrode 2, which is a through-hole electrode of the first circuit board B1, or alternatively extends from the end on the Z'-direction side of the second side plate of the first sheath body 31 in the X' direction and is connected to a corresponding first ground electrode 2, which is a surface electrode of the first circuit board B1. It should be noted that the plurality of first legs 33 and the plurality of second legs 33 can be omitted.

[0206] The first sheath 30 can further comprise a plurality of locking pieces. The plurality of locking pieces is a plurality of first locking pieces 34, a plurality of second locking pieces 35, and / or a plurality of third locking pieces 36. Each of the first locking pieces 34 is a curved piece provided at the end on the Z'-direction side of the first side plate or at the end on the Z'-direction side of the second side plate of the first sheath body 31, and rests against the first body 10 from the Z'-direction side. Each of the second locking pieces 35 is a curved piece provided at one end on the Z'-direction side of the first cover 32, and rests against the first body 10 from the Z'-direction side.Each of the third locking pieces 36 is a bent piece with a general L-shape at one end on the X-direction side or one end on the X'-direction side of the first cover 32 and is received in a corresponding locking groove 11b of the first body 10 from the Z'-direction side.

[0207] The plurality of locking pieces of the first sheath 30 can be omitted. If the plurality of third locking pieces 36 is omitted, the locking grooves 11b of the first body 10 are also omitted.

[0208] The second printed circuit board B2 is spaced apart from, and relative to, the first printed circuit board B1 on the Z-direction side. The second printed circuit board B2 has a similar configuration to the first printed circuit board B1. The plurality of first electrodes 1 of the second printed circuit board B2 are surface electrodes provided at intervals in the X-X' direction on a surface on the Z-direction side of the second printed circuit board B2, or alternatively, through-hole electrodes provided at intervals in the X-X' direction in the second printed circuit board B2. The plurality of second ground electrodes 2 of the second printed circuit board B2 are surface electrodes provided on the surface on the Z-direction side of the second printed circuit board B2 and connectable to ground, or alternatively, through-hole electrodes provided in the second printed circuit board B2 and connectable to ground.The plurality of second access holes 3 of the second circuit board B2 extends through the second circuit board B2 in the Z-Z' direction. The plurality of second ground electrodes 2 and / or the plurality of second access holes 3 can be omitted.

[0209] The second mating connector MC2 (a secondary connector) may have a similar design to the first mating connector MC1, but may differ in that the second mating connector MC2 is mounted on the second circuit board B2 from the Z-direction side and can be detachably connected from the Y-direction side to the second connector part FC2 of the floating connector FC. The term "second normal position," as used here, refers to a state in which the second mating connector MC2 is spaced from, and relative to on the Z-direction side to, the first mating connector MC1, and coincides with the first mating connector MC1 in the Y-Y' and X-X' directions.The term "partially connected state" refers to a state in which the second connector part FC2 of connector FC, as described above, is at least partially mechanically connected to the second mating connector MC2 in the Y-Y' direction, but is movable relative to the second mating connector MC2 in the Y direction; the term "second connection state (fully connected state)" refers to a state in which the second connector part FC2 of connector FC, as described above, is fully mechanically and electrically connected to the second mating connector MC2 in the Y-Y' direction and is no longer movable relative to the second mating connector MC2 in the Y direction. The second mating connector MC2 differs from the first mating connector MC1 in the following points.

[0210] The semi-connected state can be caused, for example, by the following non-restrictive factors (a) to (d).

[0211] (a) A case in which the second mating connector MC2 is in the second normal position relative to the first mating connector MC1 and an insertion force required for the connection between the second mating connector MC2 and the second connector part FC2 (for example, a force against the dynamic frictional force generated at a point where the second mating connector MC2 and the second connector part FC2 contact each other when connected) is greater than the reaction force (restoring force) generated when the elastically deformable sections 230 of the plurality of terminals 200 of the connector FC are elastically deformed.

[0212] (b) A case in which the second mating connector MC2 is in the second normal position and the insertion force is less than the reaction force (except for a case in which the difference between the insertion force and the reaction force is nearly zero).

[0213] (c) A case in which the ratio between the insertion force and the reaction force is irrelevant (the two forces may be equal or different), but the second mating connector MC2 is in a position offset from the second normal position relative to the first mating connector MC1 in the Y' direction.

[0214] (d) A case in which the second mating connector MC2 is in a position offset from the second normal position relative to the first mating connector MC1 in the Y direction (however, this depends on the ratio between the offset measure, the insertion force and the reaction force).

[0215] The second body 10 of the second mating connector MC2 can be identical in shape to the first body 10 of the first mating connector MC1 (see Fig. 1A to 2D and 8A to 10B). Alternatively, the second body 10 of the second mating connector MC2 can be similar in design to the first body 10 of the first mating connector MC1 described above, but differ in shape (not shown). Accordingly, the second body 10 and its sub-elements are referred to using the same reference numerals as the first body 10 and its sub-elements.

[0216] For example, the second body 10 can comprise the base 11 and the projection 12 described above. As described above, the base 11 is provided with the plurality of mounting grooves 11a. The projection 12 can, as described above, be provided with the plurality of mounting holes 12a and the plurality of connecting holes 12b, or alternatively, with the plurality of mounting holes 12a but not with the plurality of connecting holes 12b. In the partially connected state, the projection 12 of the second body 10 is partially inserted into the (incompletely mechanically connected to the) second connecting space of the second shell body 310b of the second connector part FC2 of the connector FC.In the second connection state, the projection 12 of the second body 10 is inserted into the second connection space of the second sheath body 310b of the second connector part FC2 of the connector FC and rests against the main section 110b of the second body 100b of the second connector part FC2.

[0217] The second body 10 can further comprise the tubular section 13 described above. The tubular section 13 and the projection 12 define a second insertion space with a general ring shape (e.g., a polygonal ring shape, such as a general quadrilateral ring shape (see Fig. 8A to Fig. 10B) or a general circular ring shape (not shown).

[0218] When the second connector part FC2 is provided with the second housing 400, the distal section of the second housing body 410 of the second housing 400 of the second connector part FC2 is partially inserted into the (incompletely mechanically connected to the) second insertion space in the semi-connected state. In this case, the distal section of the second housing body 410 of the second housing 400 of the second connector part FC2 is fully inserted into the second insertion space in the Y-Y' direction in the second connection state.

[0219] If the second connector part FC2 is not fitted with the second housing 400, the distal section of the second jacket body 310b of the second jacket 300b of the second connector part FC2 is partially inserted into the (incompletely mechanically connected to the) second insertion space in the semi-connected state. In this case, the distal section of the second jacket body 310b of the second jacket 300b of the second connector part FC2 is fully inserted into the second insertion space in the Y-Y' direction in the second connection state.

[0220] The upper plate of the tubular section 13 may be provided with the indentation 13c. The indentation 13c is as described above. In the semi-connected or second-connected state, the disk 610a of the rotary lever 600 of the second connector part FC2 is partially received in the indentation 13c. The indentation 13c may have a curved surface that curves along the outer circumferential surface of the disk 610a. This arrangement prevents interference between the disk 610a of the rotary lever 600 and the second body 10 of the second mating connector MC2. The central axis of the curved surface of the indentation 13c may be positioned on the Y'-direction side relative to a distal surface on the Y'-direction side of the second body 10.

[0221] The second mating connector MC2 further includes the abutment 14. The abutment 14 is a projection on a bottom surface of the recess 13c and projects in the Z-direction. If the recess 13c is not provided, the abutment 14 is a projection on the upper plate of the tubular section 13 and projects in the Z-direction.

[0222] The base plate of the tubular section 13 can be provided with a plurality of engagement projections 15 that project in the Z' direction. The plurality of engagement projections 15 are inserted into the respective second engagement holes 3 of the second circuit board B2. The base plate of the tubular section 13 can also be provided with the locking recess 13b. The engagement projection 15 and / or the locking recess 13b can be omitted.

[0223] The second mating connector MC2 comprises at least one second terminal 20, which can be a single second terminal 20 or a plurality of second terminals 20. For the sake of simplicity, the at least one second terminal 20 is described as a plurality of second terminals 20. However, even in a case where a single second terminal 20 is provided, the second terminal 20 can be configured similarly to each of the second terminals 20.

[0224] Each of the multiple second connections 20 of the second mating connector MC2 can be identical in form to each of the first connections 20 of the first mating connector MC1 (see Fig. 3A, Fig. 3B, Fig. 11A and Fig. 11B). Alternatively, each of the multiple second terminals 20 can be similar in design to each of the first terminals 20 of the first mating connector MC1 described above, but differ in form (not shown). Accordingly, the second terminals 20 and their sub-elements are referred to using the same reference numerals as the first terminals 20 and their sub-elements.

[0225] The second retainable sections 22 of the plurality of second connections 20 are generally L-shaped plates and are securely received from the Y-direction side in the respective retaining grooves 11a of the base 11 of the second body 10 and the respective retaining holes 12a of the projection 12. Thus, the second retainable sections 22 of the plurality of second connections 20 are held at intervals in the X-X' direction in the second body 10.

[0226] The second contact sections 21 of the plurality of second terminals 20 can extend from the corresponding second connecting sections 24 in the Y' direction. Each of the second contact sections 21 of the plurality of second terminals 20 can be formed by a plate (not shown), a rod (not shown), or a tube (not shown) and have a forked shape encompassing the first and second contact arms 21a (see Fig. 2A, 2B, 3A, 3B and 9A to 11B). The second contact sections 21 of the plurality of second terminals 20 project at least partially from the second body 10 or are at least partially exposed from it, such that they are visible from the Y' direction side.

[0227] When the second body 10 comprises the plurality of connection holes 12b, the second contact sections 21 of the plurality of second terminals 20 are arranged in the respective connection holes 12b from the Y-direction side and are at least partially exposed in the Y' direction from the respective connection holes 12b. In the semi-connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, are received from the Y' direction side into the respective connection holes 12b of the second body 10, slide onto the respective second contact sections 21 of the plurality of second terminals 20 at a distance in the Y-Y' direction that is less than a predetermined distance, and are in contact with the respective second contact sections 21.In this case, in the second connection state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, are received from the Y'-direction side into the respective connection holes 12b of the second body 10, slide at the predetermined distance onto the respective second contact sections 21 of the plurality of second terminals 20 and are in contact with the respective second contact sections 21.Alternatively, in the partially connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, are received from the Y'-direction side into the respective connection holes 12b of the second body 10, but cannot be in contact with the respective second contact sections 21 of the plurality of second terminals 20. In this case, in the fully connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, are received from the Y'-direction side into the respective connection holes 12b of the second body 10 and are in contact with the respective second contact sections 21 of the plurality of second terminals 20.

[0228] If the second body 10 does not include the plurality of connection holes 12b, the second contact sections 21 of the plurality of second terminals 20 project at least partially from their respective mounting holes 12a in the Y' direction. In the partially connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, can slide onto the respective second contact sections 21 of the plurality of second terminals 20 at a distance in the Y-Y' direction that is smaller than the predetermined distance, and are in contact with the respective second contact sections 21.In this case, in the second connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, slide at the predetermined distance onto the respective second contact sections 21 of the plurality of second terminals 20 and are in contact with the respective second contact sections 21. Alternatively, in the partially connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, may not be in contact with the respective second contact sections 21 of the plurality of second terminals 20.In this case, in the second connected state, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of the connector FC, which project at least partially from the second body 100b, are in contact with the respective second contact sections 21 of the plurality of second terminals 20. Alternatively, in the partially connected state, the second contact sections 21 of the plurality of second terminals 20 can be received in the respective connecting holes of the second body 100b of the second connector part FC2 of the connector FC and slide onto the respective second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 at a distance in the Y-Y' direction that is smaller than the predetermined distance, and are in contact with the respective second contact sections 210b.In this case, in the second connected state, the second contact sections 21 of the plurality of second terminals 20 are received in the respective connecting holes of the second body 100b of the second connector part FC2 of the connector FC, slide at the predetermined distance onto the respective second contact sections 210b of the plurality of terminals 200 of the second connector part FC2, and are in contact with the respective second contact sections 210b. Alternatively, in the partially connected state, the second contact sections 21 of the plurality of second terminals 20 are received in the respective connecting holes of the second body 100b of the second connector part FC2 of the connector FC, but cannot be in contact with the respective second contact sections 210b of the plurality of terminals 200 of the second connector part FC2.In this case, in the second connection state, the second contact sections 21 of the plurality of second terminals 20 are received in the respective connection holes of the second body 100b of the second connector part FC2 of the connector FC and are in contact with the respective second contact sections 210b of the plurality of terminals 200 of the second connector part FC2.

[0229] If the second contact section 210b of each terminal 200 of the second connector part FC2 of the connector FC is formed by a plate or rod inclined in the second inclined direction (see Fig. 3A, Fig. 3B, Fig. 11A and Fig. 11B), the second connecting section 24 of each second terminal 20 can be bent or curved such that the first contacting arm 21a and the second contacting arm 21a of the second contacting section 21 of each second terminal 20 can be elastically contacted with the first surface 211b and the second surface 212b of the corresponding second contacting section 210b from one side and the other side of a fourth oblique direction (essentially perpendicular to the first surface 211b and the second surface 212b, respectively), wherein the fourth oblique direction is essentially orthogonal to the second oblique direction.Alternatively, the second connecting section 24 of each second terminal 20 can be bent or curved such that the plate- or rod-shaped second contacting section 21 of each second terminal 20 can be contacted with the first surface 211b or the second surface 212b of the corresponding second contacting section 210b from one side or the other side of the fourth inclined direction.

[0230] If the second contact section 210b of each terminal 200 of the second connector part FC2 of the connector FC includes the first and the second contact arm inclined in the second inclined direction (not shown), the second linking section 24 of each second terminal 20 may be bent or curved such that the first and second surfaces of the second contact section 21 of each second terminal 20 are inclined in the fourth inclined direction, and the first and second contact arms of the second contact section 210a are elastically contactable with the first and second surfaces of the corresponding second contact section 21 from one side and the other side of the second inclined direction (essentially perpendicular to the first and second surfaces of the second contact section 21).

[0231] The second linking sections 24 of the plurality of second connections 20 cannot be bent or curved, but extend straight from the corresponding second holdable sections 22 to the corresponding second contacting sections 21 (not shown).

[0232] The second interconnection sections 24 of the plurality of second terminals 20 can be omitted. In this case, the second contact sections 21 of the plurality of second terminals 20 can extend from the corresponding second retainable sections 22 in the Y' direction.

[0233] The second conductor sections 23 of the plurality of second terminals 20 can extend from the corresponding second retainable sections 22 in the Y-direction, be arranged relative to the second body 10 on the Y-direction side, and be connected to the respective second electrodes 1, which are surface electrodes of the second circuit board B1. Alternatively, the second conductor sections 23 of the plurality of second terminals 20 can extend from the corresponding second retainable sections 22 in the Z'-direction, be arranged relative to the second body 10 on the Z'-direction side, and be connected to the respective second electrodes 1, which are through-hole electrodes of the second circuit board B2.

[0234] The second sheath 30 of the second mating connector MC2 can be identical in shape to the first sheath 30 of the first mating connector MC1 (see Fig. 1A to 2D, and 8A to 10B). Alternatively, the second sheath 30 of the second mating connector MC2 can be similar in design to the second sheath 300b of the first mating connector MC1 described above, but differ in shape (not shown). Accordingly, the second sheath 30 and its sub-elements are referred to using the same reference numerals as the first sheath 30 and its sub-elements.

[0235] The second shell body 31 of the second shell 30 has a general U-shape (not shown) or a general ring shape (a polygonal ring shape, such as a general quadrilateral ring shape, or a general circular ring shape (not shown)) in a sectional view along the Z-Z' and X-X' directions. The second shell body 31 of the second shell 30 extends in the Y-Y' direction. In cross-section along the Z-Z' and X-X' directions, the second shell body 31 has an internal shape and size that correspond to the external shape and size of the second body 10. The second body 10 is at least partially incorporated into the second shell body 31 from the Y-direction side. The second mantle body 31 comprises an upper plate on the Z-direction side, a first side plate on the X-direction side and a second side plate on the X'-direction side.

[0236] When the tubular section 13 of the second body 10 is provided with the first slot 13a and the second slot 13a, the first side plate and the second side plate of the second jacket body 31 are exposed to the inside of the second jacket body 31 via the first slot 13a and the second slot 13a, respectively. In the partially connected state, the second connecting section 330b on the X-direction side and the second connecting section 330b on the X'-direction side of the second jacket 300b of the second connector part FC2 of the connector FC are received in the first slot 13a and the second slot 13a, respectively, but have not reached their respective predetermined contact positions relative to the first side plate and the second side plate of the second jacket body 31 in the Y-Y' direction, and are not in elastic contact with the first side plate and the second side plate of the second jacket body 31.Alternatively, in the partially connected state, the second connecting section 330b on the X-direction side and the second connecting section 330b on the X'-direction side of the second jacket 300b of the second connector part FC2 of the connector FC are received in the first slot 13a and the second slot 13a, respectively, and are in elastic contact with the first side plate and the second side plate of the second jacket body 31, respectively, but have not reached their respective predetermined contact positions relative to the first side plate and the second side plate of the second jacket body 31 in the Y-Y' direction. In the second connected state, the second connecting section 330b on the X-direction side and the second connecting section 330b on the X'-direction side of the second jacket 300b of the second connector part FC2 of the connector FC are received in the first slot 13a and the second slot 13a, respectively.The second slot 13a is received and are in elastic contact with the first side plate and the second side plate of the second jacket body 31, respectively, in their respective predetermined contact positions. Thus, in the second connection state, the second jacket 30 is electrically fully connected to the second jacket 300b of the second connector part FC2 of the connector FC. If the tubular section 13 of the second body 10 is omitted, the distal section of the second jacket body 310b of the second jacket 300b of the connector FC is in the semi-connected state, partially inserted into the (incompletely mechanically connected to the) second insertion space and in contact with the second jacket body 31, but has not reached a predetermined contact position relative to the second jacket body 31 in the Y-Y' direction.In the second connection state, the distal section of the second jacket body 310b of the second jacket 300b of connector FC is fully inserted into the second insertion space and in contact with the second jacket body 31. Furthermore, in this way, the second jacket 30 is electrically connected to the second jacket 300b of the second connector part FC2 of connector FC in the second connection state.

[0237] The upper plate of the second shell body 31 is provided with the cutout 31a or an opening to expose the abutment 14 towards the Z-direction. If the indentation 13c is present, the cutout 31a, when viewed from the Z-direction side, can be identical in shape to the indentation 13c, and, when viewed from the Z-direction, its projected area can be equal to or larger than that of the indentation 13c.

[0238] The second cover 32 of the second sheath 30 is a plate that adjoins the end on the Y-direction side of the upper plate of the second sheath body 31 and covers the second body 10 from the Y-direction side. The second cover 32 can be omitted.

Each of the first legs 33 extends from the end on the Z'-direction side of the first side plate of the second sheath body 31 in the Z' direction and is connected to a corresponding second ground electrode 2, which is a through-hole electrode of the second circuit board B2, or alternatively extends from the end on the Z'-direction side of the first side plate of the second sheath body 31 in the X direction and is connected to a corresponding second ground electrode 2, which is a surface electrode of the second circuit board B2.Each of the second legs 33 extends from the end on the Z'-direction side of the second side plate of the second sheath body 31 in the Z' direction and is connected to a corresponding second ground electrode 2, which is a through-hole electrode of the second circuit board B2, or alternatively extends from the end on the Z'-direction side of the second side plate of the second sheath body 31 in the X' direction and is connected to a corresponding second ground electrode 2, which is a surface electrode of the second circuit board B2.

[0240] The second sheath 30 can further comprise a plurality of locking pieces. The plurality of locking pieces is a plurality of first locking pieces 34, a plurality of second locking pieces 35, and / or a plurality of third locking pieces 36. Each of the first locking pieces 34 is a curved piece provided at the end on the Z'-direction side of the first side plate or at the end on the Z'-direction side of the second side plate of the second sheath body 31, and rests against the second body 10 from the Z'-direction side.

[0241] The multiple locking elements of the second jacket 30 can be omitted. If the multiple locking elements of the third jacket 36 are omitted, the locking grooves 11b of the second body 10 are also omitted.

[0255] A linear distance D (linear distance in the Y-Y' direction in the unlocked state (first linear distance)) from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2 is greater than one dimension d' of the abutment 14 in the Y-Y' direction. A linear distance d (linear distance in the Y-Y' direction in the unlocked state (second linear distance)) from the first end to the second end of the third wall surface 613b1 is less than the linear distance D. The linear distance d can be the same as, or slightly greater than, the dimension d'. The difference between the linear distance D and the dimension d' is an insertion margin C (an insertion dimension) in the opening 613a for the abutment 14.A linear distance (third linear distance) from the inner circumferential surface 613c to the outer circumferential surface 613d in the normal direction of the inner circumferential surface 613c gradually decreases from the second end of the first wall surface 613a1 to the second end of the third wall surface 613b1.

[0256] The central axis of the inner circumferential surface 613c coincides with the axis of rotation P1, but the central axis P2 of the outer circumferential surface 613d can be offset by a linear distance D1 (a linear distance in the Y-Y' direction in the unlocked state (fourth linear distance)) from the axis of rotation P1 in the direction of the opening 613a (to the Y-direction side in the unlocked state) (see Fig. 2C and Fig. 2D). A linear distance (linear distance in the Y-Y' direction in the unlocked state (fifth linear distance)) from the second end of the second wall surface 613a2 to the first end of the third wall surface 613b1 can be approximately twice a radial dimension r of the inner circumferential surface 613c (a radial distance r' from the axis of rotation P1 to the inner circumferential surface 613c). A linear distance D2 (linear distance in the Y-Y' direction in the unlocked state) from the second end of the first wall surface 613a1 to the axis of rotation P1 is greater than a linear distance D3 (linear distance in the Y-Y' direction in the unlocked state) from the second end of the third wall surface 613b1 to the axis of rotation P1.

[0257] The sum of the linear distance D1 and the difference between a radial dimension R of the outer circumferential surface 613d (radial distance from the central axis P2 to the outer circumferential surface 613d) and the radial dimension r of the inner circumferential surface 613c can be greater than a linear distance D7 (sixth linear distance). In this case, Equation 1 defined below applies. The linear distance D7 is a linear distance in the Y-Y' direction from the end on the Y-direction side of the abutment 14 in the second mating connector MC2 to a distal surface on the Y'-direction side of the second mating connector MC2 (e.g., the distal surface on the Y'-direction side of the second body 10). It should be noted that in the first embodiment, the linear distance D7 is the same as the dimension d', but that the linear distance D7 of the invention is not limited to this. R−r+D1≥D7

[0258] In the unlocked state, when the second connector part FC2 is connected to the second mating connector MC2 from the Y'-direction side in the second connection state (not shown), the abutment 14 is received from the opening 613a of the locking groove 613 through the first chamber 613e1 of the insertion section 613e into the second chamber 613e2 of the insertion section 613e. The abutment 14 can abut the area 613c1 of the opening side of the inner circumferential surface 613c or face the area 613c1 of the opening side with a small gap between them. In a state in which the abutment 14 is thus received in the second chamber 613e2 (in the second connection state), the rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the second chamber 613e2 to the deep section 613b or to the intermediate section 613f in the locking groove 613.During this movement, the abutment 14 is not in contact with the outer circumferential surface 613d of the locking groove 613 and is not pushed from the Y-direction side, but in a state where the abutment 14 has reached the deep section 613b or the intermediate section 613f, the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613. Alternatively, the abutment 14 is not in contact with the outer circumferential surface 613d of the locking groove 613 while moving relative to a point between the second space 613e2 and the deep section 613b or the intermediate section 613f, but the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613 after passing the aforementioned point, until it reaches the deep section 613b or the intermediate section.

[0259] In the unlocked state, when the second connector part FC2 is connected from the Y' direction side to the second mating connector MC2 in the half-connected state (see Fig. 2D), the abutment 14 is at least partially received by the opening 613a into the first chamber 613e1 of the introduction section 613e. For example, the entire abutment 14 may be received in the first chamber 613e1, or a section on the Y-direction side of the abutment 14 may be received in the opening 613a and a section on the Y'-direction side of the abutment 14 may be received in the first chamber 613e1.In a state where the abutment 14 is thus at least partially received in the first chamber 613e1 (in the semi-connected state), rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the first chamber 613e1 to the deep section 613b or to the intermediate section 613f in the locking groove 613 and is also pressed against the outer circumferential surface 613d of the locking groove 613 from the Y-direction side (from the side of the mating connector MC2). This moves the second connector part FC2 relative to the second mating connector MC2 in the Y-direction, and transitions the second connector part FC2 from the semi-connected state to the second connected state with respect to the second mating connector MC2.

[0260] It should be noted that the linear distance d, the radial dimension r, the radial dimension R, the introduction margin C, and the linear distance D can be defined as ratio equations, which are listed below in Table 1. The ratio equations are non-restrictive examples. Table 1 Symbol Verhältnisgleichung d = d' r = r' C Einführungsrand D = C + d= C + d R = (d + 2r + D) / 2=d+r+C / 2 Abstand r - R = R - (d + r)=C / 2

[0261] If the indentation 13c is provided, a linear distance D4 can be essentially the same as a linear distance D5, wherein the linear distance D4 is a linear distance in the Y-Y' direction from the central axis of the curved surface of the indentation 13c to the distal surface on the Y'-direction side of the second body 10, and the linear distance D5, in the unlocked state, is a linear distance in the Y-Y' direction from the axis of rotation P1 to the second end of the second wall surface 613a2. In this case, even when the second connector part FC2 is in the second connection state with respect to the second mating connector MC2, the rotary lever 600 can rotate between the unlocked and locked positions while avoiding interference between the rotary lever 600 and the curved surface of the indentation 13c.

[0262] For example, a difference S between linear distance D2 and linear distance D3 can be the same as the difference between linear distance D6 and linear distance D7. Linear distance D6 is a linear distance (linear distance in the Y-Y' direction in the unlocked state) from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2. In this case, by adjusting the difference S between linear distance D2 and linear distance D3, it is possible to set a permissible float dimension of the second connector part FC2 to the Y-direction side, i.e., a permissible offset dimension of the second circuit board B2 relative to the first circuit board B1 to the Y-direction side. For example, if D7 = 2 mm and D6 = 4 mm, then S = D6 - D7 = 2 mm.This means that even if the second mating connector MC2 is displaced by a maximum of 2 mm towards the Y-direction relative to the first mating connector MC1, the second mating connector MC2 can be fully inserted by turning the rotary lever 600. In this case, the permissible float of the second connector part FC2 towards the Y-direction is 2 mm.

[0263] The locking groove 613 of the rotary lever 600 described above can be modified in any way, provided that, in the unlocked state, the abutment 14 of the second mating connector MC2 is at least partially received into the insertion section 613e by the opening 613a of the locking groove 613 of the rotary lever 600 of the second connector part FC2, by connecting the second connector part FC2 to the second mating connector MC2 from the Y'-direction side in the semi-connected state, and that the abutment 14 is engaged by rotating the rotary lever 600 from the unlocked position to the locked position when the abutment 14 is received into the insertion section 613e.relative to the inlet section 613e to the deep section 613b or to the intermediate section 613f in the locking groove 613, and is also pressed from the Y-direction side by the outer circumferential surface 613d of the locking groove 613 such that the second connector part FC2 is moved relative to the second mating connector MC2 in the Y-direction. It should be noted that the lever body 610 of the rotary lever 600 described above is not limited to a lever body with the disc 610a and the handle 610b, but that the lever body 610 can have any other external shape.

[0264] The following describes non-restrictive methods for connecting the first connector part FC1 of the floating connector FC to the first mating connector MC1.

[0265] The first connector part FC1 is connected to the first mating connector MC1 from the Y' direction side. When the first connector part FC1 is connected to the first mating connector MC1, the distal section of the retaining section 720 of the first housing 700 (if provided) of the first connector part FC1, or the distal section of the first sheath body 310a of the first sheath 300a (if the first housing 700 is not provided), is inserted from the Y' direction side into the first insertion space defined by the tubular section 13 and the projection 12 of the first body 10 of the first mating connector MC1. The projection 12 of the first mating connector MC1 is then inserted into the first connection space of the first sheath body 310a of the first connector part FC1 and is brought into contact with the main section 110a of the first body 100a of the first connector part FC1.

[0266] If the first body 10 of the first mating connector MC1 comprises the plurality of connection holes 12b, when the first connector part FC1 is connected to the first mating connector MC1, the first contact sections 210a of the plurality of terminals 200 of the first connector part FC1, which project at least partially from the first body 100a, are inserted from the Y'-direction side into the respective connection holes 12b of the first body 10 of the first mating connector MC1 and are brought into contact with the respective first contact sections 21 of the plurality of first terminals 20 of the first mating connector MC1.

[0267] If the first body 10 does not include the plurality of connection holes 12b, when the first connector part FC1 is connected to the first mating connector MC1, the first contact sections 210a of the plurality of terminals 200 of the first connector part FC1, which project at least partially from the first body 100a, are brought into contact with the respective first contact sections 21 of the plurality of first terminals 20 of the first mating connector MC1, which project at least partially from the first body 10. Alternatively, the first contact sections 21 of the plurality of terminals 20, which project at least partially from the first body 10, are inserted into the respective connection holes of the second body 100b of the first connector part FC1 and brought into contact with the respective first contact sections 210a of the plurality of first terminals 200 of the first connector part FC1.

[0268] If the first contact section 210a of each of the terminals 200 of the first connector part FC1 is formed by a plate or rod inclined in the first inclined direction (see 3A, 3B, 11A and 11B), the first contact arm 21a and the second contact arm 21a of the first contact section 21 of each first terminal 20 of the first mating connector MC1 are brought into elastic contact substantially perpendicularly with the first surface 211a and the second surface 212a of the first contact section 210a of each of the terminals 200 of the first connector part FC1.

[0269] When the tubular section 13 of the first mating connector MC1 is provided with the first slot 13a and the second slot 13a, and when the first mating connector MC1 is connected to the first connector part FC1, the first connecting section 330a on the X-direction side and the first connecting section 330a on the X'-direction side of the first sheath 300a of the first connector part FC1 are inserted into the first slot 13a and the second slot 13a of the first mating connector MC1, respectively, and brought into elastic contact with the first side plate and the second side plate of the first sheath body 31 of the first sheath 30 of the first mating connector MC1. This electrically connects the first sheath 30 of the first mating connector MC1 to the first sheath 300a of the first connector FC1.

[0270] If the locking arm 750 of the first housing 700 of the connector FC is provided and the tubular section 13 of the first mating connector MC1 is provided with the locking recess 13b, the locking arm 750 is locked in the locking recess 13b when the first connector part FC1 is connected to the first mating connector MC1. This makes it possible to maintain the initial connection state in which the first connector part FC1 is fully mechanically and electrically connected to the first mating connector MC1. The initial connection state between the first connector part FC1 and the first mating connector MC1 is not released unless the locking of the locking arm 750 with the locking recess 13b is released.Therefore, in an environment where the CB1 connection structure is used, even if the first connector part FC1 and / or the first mating connector MC1 are subjected to external vibrations or shocks, the first connection state will not break or change to the semi-connected state (a state in which the first connector part FC1 is at least mechanically connected to the first mating connector MC1 from the Y' direction side, but is movable in the Y direction relative to the first mating connector MC1). Therefore, the CB1 connection structure is suitable as a connection structure requiring vibration and shock resistance.

[0271] The following describes non-restrictive methods for connecting the second connector part FC2 of the floating connector FC to the second mating connector MC2.

[0272] The second connector part FC2 is connected to the second mating connector MC2 from the Y' direction side.When the second connector part FC2 is connected to the second mating connector MC2, the distal section of the second housing body 410 of the second housing 400 (if provided) of the second connector part FC2 or the distal section of the second jacket body 310b of the second jacket 300b of the second connector part FC2 (if the second housing 400 is not provided) is inserted from the Y'-direction side into the second insertion space defined by the tubular section 13 and the projection 12 of the second body 10 of the second mating connector MC2, and the projection 12 of the second mating connector MC2 is inserted into the second connection space of the second jacket body 310b of the second connector part FC2 and brought into contact with the main section 110b of the second body 100b of the second connector part FC2.

[0273] If the second body 10 of the second mating connector MC2 includes the plurality of connection holes 12b, when the second connector part FC2 is connected to the second mating connector MC2, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2, which project at least partially from the second body 100b, are inserted from the Y'-direction side into the respective connection holes 12b of the second body 10 of the second mating connector MC2 and are brought into contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2.

[0274] If the second body 10 does not include the plurality of connection holes 12b, when the second connector part FC2 is connected to the second mating connector MC2, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2, which project at least partially from the second body 100b, are brought into contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2, which also project at least partially from the second body 10. Alternatively, the second contact sections 21 of the plurality of second terminals 20, which project at least partially from the second body 10, are inserted into the respective connection holes of the second body 100b of the second connector part FC2 and brought into contact with the respective second contact sections 210b of the plurality of second terminals 200 of the second connector part FC2.

[0275] If the second contact section 210b of each of the plurality of terminals 200 of the second connector part FC2 is formed by a plate or rod inclined in the third inclined direction (see 3A, 3B, 11A and 11B), the first contact arm 21a and the second contact arm 21a of the second contact section 21 of each of the second terminals 20 of the second mating connector MC2 are brought into elastic contact substantially perpendicularly with the first surface 211a and the second surface 212a of the second contact section 210b of each of the plurality of terminals 200 of the second connector part FC2.

[0276] When the tubular section 13 of the second mating connector MC2 is provided with the first slot 13a and the second slot 13a, and when the second mating connector MC2 is connected to the second connector part FC2, the second connecting section 330b on the X-direction side and the second connecting section 330b on the X'-direction side of the second jacket 300b of the second connector part FC2 are inserted into the first slot 13a and the second slot 13a of the second mating connector MC2, respectively, and brought into elastic contact with the first side plate and the second side plate of the second jacket body 31 of the second jacket 30 of the second mating connector MC2. This electrically connects the second jacket 30 of the second mating connector MC2 to the second jacket 300b of the second connector FC2.

[0277] Even in a case where the first printed circuit board B1 and the second printed circuit board B2 are mounted in an electronic device (not shown) to install the first printed circuit board B1 and the second printed circuit board B2, and where the second mating connector MC2 is in a position in which the component of the direction encompassing at least one direction is offset from the second normal position with respect to the first mating connector MC1, the elastically deformable sections 230 of the plurality of terminals 200 of the second connector part FC2 deform elastically in the direction encompassing the component of the direction encompassing at least one direction when the second mating connector MC2 is connected to the second connector part FC2, such that the second connector part FC2 is displaced in the same direction.In other words, when the second mating connector MC2 is connected to the second connector part FC2, the second connector part FC2 is shifted according to the offset position of the second mating connector MC2 in the direction encompassing one component, the direction encompassing two components, or the direction encompassing three components, as described above. This allows for easy connection of the second connector part FC2 to the second mating connector MC2.

[0278] The rotary lever 600, in its unlocked state, is rotated approximately 180 degrees. This disengages the locking projection 450 on the X'-direction side of the second housing 400 from the locking recess 614 of the rotary lever 600. Once the rotary lever 600 has been rotated approximately 180 degrees, the locking projection 450 on the X'-direction side of the second housing 400 is inserted into the locking recess 614, and the rotary lever 600 enters the locked state. During the rotation of the rotary lever 600, the abutment 14 is inserted into the locking groove 613 of the rotary lever 600 and then locked therein. When the rotary lever 600 is rotated approximately 180 degrees in the opposite direction, it enters the unlocked state.

[0279] When the second connector part FC2 is connected to the second mating connector MC2 from the Y'-direction side, the abutment 14, when the second connector part FC2 is connected to the second mating connector MC2 in the second connection state, is received from the opening 613a of the locking groove 613 through the first chamber 613e1 of the insertion section 613e into the second chamber 613e2 of the insertion section 613e. In the second connection state, rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the second chamber 613e2 to the deep section 613b or to the intermediate section 613f in the locking groove 613.At this point, the abutment 14 is not pressed from the Y-direction side against the outer circumferential surface 613d of the locking groove 613, but when the abutment 14 reaches the deep section 613b or the intermediate section 613f, the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613. Alternatively, the abutment 14 is not pressed from the outer circumferential surface 613d of the locking groove 613 while moving relative to the point between the second space 613e2 and the deep section 613b or the intermediate section 613f, but the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613 after passing the point, until it reaches the deep section 613b or the intermediate section.

[0280] When the second connector part FC2 is connected to the second mating connector MC2 from the Y'-direction side, the abutment 14, when the second connector part FC2 is in a semi-connected state, is at least partially received by the opening 613a into the first chamber 613e1 of the insertion section 613e. In this semi-connected state, rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the first chamber 613e1 towards the deep section 613b or the intermediate section 613f in the locking groove 613 and is also pressed from the Y-direction side against the outer circumferential surface 613d of the locking groove 613.Thus, the second connector part FC2 is moved relative to the second mating connector MC2 in the Y-direction, and the second connector part FC2 is transferred from the partially connected state to the second fully connected state with respect to the second mating connector MC2. At this point, the second connector part FC2, which is in a partially inserted state with respect to the second mating connector MC2, is fully inserted into the second mating connector MC2 and mechanically fully connected to it in one of the ways described above, and the second connector part FC2 is electrically fully connected to the second mating connector MC2 in the manner described below.

[0281] In the semi-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of connector FC slide onto the respective second contact sections 21 of the plurality of second terminals 20 and are in contact with the respective second contact sections 21 at a distance in the Y-Y' direction that is smaller than the predetermined distance, the outer circumferential surface 613d of the locking groove 613 pushes the abutment 14 from the Y-direction side to move the second connector part FC2 relative to the second mating connector MC2 in the Y-direction such that the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 slide onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2 by the remaining distance of the predetermined distance, such that the state,in which the multitude of second connections 20 are in contact with the respective second contact sections 21 is maintained.

[0282] In the semi-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 of connector FC are not in contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2, the outer circumferential surface 613d of the locking groove 613 pushes the abutment 14 from the Y-direction side to move the second connector part FC2 relative to the second mating connector MC2 in the Y-direction, such that the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 slide onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2 at the predetermined distance, such that the state in which the plurality of second terminals 20 are in contact with the respective second contact sections 21 is maintained.

[0283] The FC connector described above provides the following technical features and effects (1) and (2).

[0284] Technical features and effects (1): By rotating the rotary lever 600 of the second connector part FC2 of the connector FC to press the abutment 14 of the second mating connector MC2 from the Y-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and moving the second connector part FC2 relative to the second mating connector MC2 in the Y-direction, the second connector part FC2, which is in a half-inserted state with respect to the second mating connector MC2, is fully inserted into the second mating connector MC2 and mechanically fully connected to it in one of the ways described above, and the second connector part FC2 is electrically fully connected to the second mating connector MC2 in one of the ways described above.

[0285] If the second mating connector MC2 is in a position offset from its normal position in the Y or Y' direction, the second connector part FC2 can be connected to the second mating connector MC2 in a semi-connected state. However, the second connector part FC2 can be moved from the semi-connected state to the fully connected state by rotating the rotary lever 600 of the second connector part FC2. This movement, from the Y-direction side, presses the abutment 14 of the second mating connector MC2 against the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and moves the second connector part FC2 relative to the second mating connector MC2 in the Y direction.

[0286] Furthermore, in the semi-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 slide onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2 at a distance smaller than the predetermined distance, the rotary lever 600 of the second connector part FC2 can be rotated into the semi-connected state in order to press the abutment 14 of the second mating connector MC2 from the Y-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and move the second connector part FC2 relative to the second mating connector MC2 in the Y-direction.The second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 slide by the remaining distance onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2. In the half-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 are not in contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2, the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2 can be engaged by rotating the rotary lever 600 of the second connector part FC2 into the half-connected state.to press the abutment 14 of the second mating connector MC2 from the Y-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and to move the second connector part FC2 relative to the second mating connector MC2 in the Y-direction, sliding at the predetermined distance onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2. In both cases, the second contact sections 210b slide at the predetermined distance onto the respective second contact sections 21 in a state in which the second connector part FC2 is fully connected to the second mating connector MC2. Even if the second mating connector MC2 is in a position that is offset in the Y- or Y'-direction from the second normal position, it is possible to ensure thatthat the second contact sections 210b slide at the predetermined distance with respect to the second contact sections 21.

[0287] Furthermore, if the linear distance D from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2 of the locking groove 613 is greater than the dimension d' in the YY' direction of the abutment 14, the linear distance d from the first end to the second end of the third wall surface 613b1 of the locking groove 613 is smaller than the linear distance D, and the linear distance from the inner circumferential surface 613c to the outer circumferential surface 613d in the radial direction of the inner circumferential surface 613c of the locking groove 613 gradually decreases from the second end of the first wall surface 613a1 to the second end of the third wall surface 613b1, it is possible by rotating the rotary lever 600,The abutment 14 of the second mating connector MC2 is pressed from the Y-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600, and the second connector part FC2 of the connector FC is moved appropriately in the Y-direction relative to the second mating connector MC2. Furthermore, if the linear distance d is equal to, or slightly greater than, the dimension d', it is possible by rotating the rotary lever 600 to move the abutment 14 from the opening 613a into the deep section 613b in the locking groove 613 of the rotary lever 600 and to hold the abutment 14 in the deep section 613b.

[0288] If the central axis of the inner circumferential surface 613c of the locking groove 613 coincides with the axis of rotation P1, but the central axis P2 of the outer circumferential surface 613d of the locking groove 613 is offset by the linear distance D1 from the axis of rotation P1 in the direction of the opening 613a (to the Y-direction side in the unlocked state), it is possible by rotating the rotary lever 600 to press the abutment 14 of the second mating connector MC2 from the Y-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and to move the second connector part FC2 of the connector FC appropriately in the Y-direction relative to the second mating connector MC2, while it is difficult for the abutment 14 of the second mating connector MC2, which moves in the locking groove 613, to align the inner circumferential surface 613c of the to contact or slide on the locking groove 613.

[0289] Technical features and effects (2): When the second connector part FC2 includes the first stop 440 and the second stop 440, the first stop 440 rests against the handle 610b of the lever body 610 from the Y-direction side when locked, and the second stop 440 rests against the handle 610b of the lever body 610 from the Y-direction side when unlocked. This arrangement prevents the rotary lever 600 from rotating beyond a predetermined rotation range.

[0290] The above-described connection structure CB1, which includes the above-described connector FC, provides similar technical features and effects to those of the above-described connector FC. Second embodiment

[0291] In the following, a connection structure CB2 (combination) of connectors according to a plurality of embodiments, comprising the second embodiment of the invention and variants thereof, is described with reference to the Fig. 12A to 12B described. The Fig. 12A to 12B represent the connection structure CB2 of the second embodiment.

[0292] The connection structure CB2 is similar in design to the connection structure CB1, but differs in that a second mating connector MC2' (a primary connector) includes the rotary lever 600, and that a floating connector FC' (which can simply be referred to as "the connector FC'" (a secondary connector)) includes a second connector part FC2' with the abutment 14. The connection structure CB2 will now be described with a focus on the differences from the connection structure CB1 and omitting overlapping descriptions.

[0293] The upper plate of the tubular section 13 of the second body 10 of the second mating connector MC2' can be provided with the indentation 13c described above.

[0294] If the bottom surface of the recess 13c is provided with a shaft 430, and the shaft 430 is the cylinder described above, which is provided on the bottom surface of the recess 13c, the shaft 430 is received in the shaft hole 611 of the lever body 610 of the rotary lever 600, and the screw or pin 620 of the rotary lever 600 is firmly received in the shaft hole of the shaft 430. Furthermore, the lever body 610 is locked around the shaft 430 on the bottom surface of the recess 13c in an unlocked position (see Fig. 12B) and a locked position (see Fig. 12A) rotatable.

[0295] If the base surface of the recess 13c is provided with the shaft hole instead of the shaft 430, the shaft hole of the second body 10 is connected to the shaft hole 611 of the lever body 610 of the rotary lever 600, and the screw or pin 620 is firmly received in the shaft hole 611 and the shaft hole of the second body 10. Furthermore, the lever body 610 is rotatable about the screw or pin 620 on the base surface of the recess 13c between an unlocked position and a locked position.

[0296] If the locking projection 450 is provided on the X-direction side and the locking projection 450 is provided on the X'-direction side, they may also be provided on the bottom surface of the recess 13c.

[0297] If the indentation 13c is omitted, the shaft 430 or the shaft hole of the second body 10 is provided on the upper plate of the second body 10. If the locking projection 450 is provided on the X-direction side and the locking projection 450 on the X'-direction side, they may also be provided on the upper plate of the second body 10.

[0298] The abutment 14 of the second connector part FC2' is a projection on the second housing body 410 of the second housing 400 and projects in the Z direction.

[0299] The following describes how the locking groove 613 of the rotary lever 600 of the second mating connector MC2' relates to the abutment 14 of the second connector part FC2'.

[0300] The opening 613a opens towards the Y' direction side when unlocked (see Fig. 12B) and opens towards the Y-direction side when locked (see Fig. 12A). The insertion section 613e of the locking groove 613 is located in the unlocked state relative to the opening 613a on the Y-direction side. The first chamber 613e1 of the insertion section 613e is located in the unlocked state relative to the opening 613a on the Y-direction side. The second chamber 613e2 of the insertion section 613e is located in the unlocked state relative to the first chamber 613e1 on the Y-direction side. In the unlocked state, the deep section 613b of the locking groove 613 is located relative to the opening 613a on the Y-direction side (directly opposite the opening 613a (see Fig. 12B), on one side of an inclined direction encompassing components of the Y and X directions (not shown), or on one side of an inclined direction encompassing components of the Y and X' directions (not shown). In the locked state, the deep section 613b is located relative to the opening 613a on the Y'-direction side (directly opposite the opening 613a (see Fig. 12A), on one side of an oblique direction encompassing components of the Y' and X' directions (not shown), or on one side of an oblique direction encompassing components of the Y' and X' directions (not shown)).

[0301] If the locking groove 613 has a general arc shape that projects towards the X-direction side when unlocked (see Fig. 12B), in the unlocked state the first wall surface 613a1 is located on one side in the X direction, the second wall surface 613a2 is located relative to the first wall surface 613a1 on the X' direction side, and the third wall surface 613b1 is located relative to the second wall surface 613a2 on the Y direction side (in particular directly opposite the second wall surface 613a2), on one side of an oblique direction comprising components of the Y and X directions, or on one side of an oblique direction comprising components of the Y and X' directions.In this case, the first end of the first wall surface 613a1 is located on the Y'-direction side relative to the second end of the first wall surface 613a1, the second end of the first wall surface 613a1 is located on the Y'-direction side relative to the first end of the first wall surface 613a1, the first end of the second wall surface 613a2 is located on the Y'-direction side relative to the second end of the second wall surface 613a2, the second end of the second wall surface 613a2 is located on the Y'-direction side relative to the first end of the second wall surface 613a2, the first end of the third wall surface 613b1 is located on the Y'-direction side relative to the second end of the third wall surface 613b1, and the second end of the third wall surface 613b1 is located on the Y'-direction side relative to the first end of the third wall surface 613b1.The inner circumferential surface 613c and the outer circumferential surface 613d of the locking groove 613 are each curved surfaces with a general arc shape that project towards the X-direction side when unlocked. When the lever body 610 encompasses the handle 610b, the handle 610b points in the X' direction when unlocked.

[0302] If the locking groove 613 has a general arc shape that projects towards the X'-direction side in the unlocked state (not shown), in the unlocked state the first wall surface 613a1 is on one side in the X' direction, the second wall surface 613a2 is on the X-direction side relative to the first wall surface 613a1, and the third wall surface 613b1 is on the Y-direction side relative to the second wall surface 613a2 (in particular, directly opposite the second wall surface 613a2, or on one side of an oblique direction comprising components of the Y and X directions, or on one side of an oblique direction comprising components of the Y and X' directions).In this case, the first end of the first wall surface 613a1 is located on the Y'-direction side relative to the second end of the first wall surface 613a1, the second end of the first wall surface 613a1 is located on the Y'-direction side relative to the first end of the first wall surface 613a1, the first end of the second wall surface 613a2 is located on the Y'-direction side relative to the second end of the second wall surface 613a2, the second end of the second wall surface 613a2 is located on the Y'-direction side relative to the first end of the second wall surface 613a2, the first end of the third wall surface 613b1 is located on the Y'-direction side relative to the second end of the third wall surface 613b1, and the second end of the third wall surface 613b1 is located on the Y'-direction side relative to the first end of the third wall surface 613b1.The inner circumferential surface 613c and the outer circumferential surface 613d of the locking groove 613 are each curved surfaces with a general arc shape that project towards the X'-direction side when unlocked. When the lever body 610 encompasses the handle 610b, the handle 610b points in the X-direction when unlocked.

[0303] A linear distance D (linear distance in the Y-Y' direction in the unlocked state (first linear distance)) from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2 is greater than one dimension d' of the abutment 14 in the Y-Y' direction. A linear distance d (linear distance in the Y-Y' direction in the unlocked state (second linear distance)) from the first end to the second end of the third wall surface 613b1 is less than the linear distance D. The linear distance d can be the same as, or slightly greater than, the dimension d'. The difference between the linear distance D and the dimension d' is an insertion edge C in the opening 613a for the abutment 14.A linear distance (third linear distance) from the inner circumferential surface 613c to the outer circumferential surface 613d in the normal direction of the inner circumferential surface 613c gradually decreases from the second end of the first wall surface 613a1 to the second end of the third wall surface 613b1.

[0304] The central axis of the inner circumferential surface 613c coincides with the axis of rotation P1, but the central axis P2 of the outer circumferential surface 613d can be offset by a linear distance D1 (a linear distance in the Y-Y' direction in the unlocked state (fourth linear distance)) from the axis of rotation P1 in the direction of the opening 613a (to the Y-direction side in the unlocked state) (see Fig. 12A and Fig. 12B). A linear distance (linear distance in the Y-Y' direction in the unlocked state (fifth linear distance)) from the second end of the second wall surface 613a2 to the first end of the third wall surface 613b1 can be approximately twice a radial dimension r of the inner circumferential surface 613c (a radial distance r' from the axis of rotation P1 to the inner circumferential surface 613c). A linear distance D2 (linear distance in the Y-Y' direction in the unlocked state) from the second end of the first wall surface 613a1 to the axis of rotation P1 is greater than a linear distance D3 (linear distance in the Y-Y' direction in the unlocked state) from the second end of the third wall surface 613b1 to the axis of rotation P1.

[0305] The sum of the linear distance D1 and the difference between a radial dimension R of the outer circumferential surface 613d (radial distance from the central axis P2 to the outer circumferential surface 613d) and the radial dimension r of the inner circumferential surface 613c can be greater than a linear distance D7' (seventh linear distance). In this case, equation 1 defined above applies. The linear distance D7' is a linear distance in the Y-Y' direction from the end on the Y'-direction side of the abutment 14 in the second connector part FC2' to a distal surface on the Y-direction side of the second connector part FC2' (e.g., the distal surface on the Y-direction side of the second housing body 410 of the second housing 400).

[0306] In the unlocked state, when the second connector part FC2' is connected to the second mating connector MC2' from the Y'-direction side in the second connection state (not shown), the abutment 14 is received from the opening 613a of the locking groove 613 through the first chamber 613e1 of the insertion section 613e into the second chamber 613e2 of the insertion section 613e. The abutment 14 can abut the area 613c1 of the opening side of the inner circumferential surface 613c or face the area 613c1 of the opening side with a small gap between them. In a state in which the abutment 14 is thus received in the second chamber 613e2 (in the second connection state), the rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the second chamber 613e2 to the deep section 613b or to the intermediate section 613f in the locking groove 613.During this movement, the abutment 14 is not in contact with the outer circumferential surface 613d of the locking groove 613 and is not pushed from the Y'-direction side, but in a state where the abutment 14 has reached the deep section 613b or the intermediate section 613f, the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613. Alternatively, the abutment 14 is not in contact with the outer circumferential surface 613d of the locking groove 613 while moving relative to a point between the second space 613e2 and the deep section 613b or the intermediate section 613f, but the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613 after passing the aforementioned point, until it reaches the deep section 613b or the intermediate section.

[0307] In the unlocked state, when the second connector part FC2' is connected from the Y-direction side to the second mating connector MC2' in the half-connected state (see Fig.12B), the abutment 14 is at least partially received by the opening 613a into the first chamber 613e1 of the introduction section 613e. For example, the entire abutment 14 may be received in the first chamber 613e1, or a section on the Y'-direction side of the abutment 14 may be received in the opening 613a and a section on the Y'-direction side of the abutment 14 may be received in the first chamber 613e1.In a state where the abutment 14 is thus at least partially received in the first chamber 613e1 (in the semi-connected state), rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the first chamber 613e1 to the deep section 613b or to the intermediate section 613f in the locking groove 613 and is also pressed from the outer circumferential surface 613d of the locking groove 613 from the Y'-direction side (from the side of the secondary connector). This moves the second connector part FC2' relative to the second mating connector MC2' in the Y direction and transitions the second connector part FC2' from the semi-connected state to the second connected state with respect to the second mating connector MC2'.

[0308] It should be noted that the linear distance d, the radial dimension r, the radial dimension R, the introduction margin C, and the linear distance D can be defined as ratio equations, which are listed above in Table 1. These ratio equations are non-restrictive examples.

[0309] For example, a difference S between the linear distance D2 and the linear distance D3 can be the same as the difference between the linear distance D6 and the linear distance D7'. The linear distance D6 is a linear distance (linear distance in the Y-Y' direction in the unlocked state) from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2. In this case, by adjusting the difference S between the linear distance D2 and the linear distance D3, it is possible to set a permissible float dimension of the second connector part FC2' to the Y-direction side, i.e., a permissible offset dimension of the second circuit board B2 relative to the first circuit board B1 to the Y-direction side. For example, if D7 = 2 mm and D6 = 4 mm, then S = D6 - D7 = 2 mm.This means that even if the second mating connector MC2' is displaced by a maximum of 2 mm towards the Y-direction relative to the first mating connector MC1, the second mating connector MC2 can be fully inserted by turning the rotary lever 600. In this case, the permissible float of the second connector part FC2' towards the Y-direction is 2 mm.

[0310] The locking groove 613 of the rotary lever 600 described above can be modified in any way, provided that, in the unlocked state, the abutment 14 of the second connector part FC2' is at least partially received into the insertion section 613e by the opening 613a of the locking groove 613 of the rotary lever 600 of the second mating connector MC2', by connecting the second connector part FC2' to the second mating connector MC2' from the Y'-direction side in the partially connected state, and that the abutment 14 is engaged by rotating the rotary lever 600 from the unlocked position to the locked position when the abutment 14 is received into the insertion section 613e.relative to the inlet section 613e to the deep section 613b or to the intermediate section 613f in the locking groove 613, and is also pressed from the Y'-direction side by the outer circumferential surface 613d of the locking groove 613 such that the second connector part FC2' is moved relative to the second mating connector MC2' in the Y direction. It should be noted that the lever body 610 of the rotary lever 600 described above is not limited to a lever body with the disc 610a and the handle 610b, but that the lever body 610 can have any other external shape.

[0311] If the second body 10 of the second mating connector MC2' is provided with the indentation 13c, the bottom surface of the indentation 13c can be provided with the two stops 440 that project in the Z direction. If the second body 10 of the second mating connector MC2' is not provided with the indentation 13c, the upper plate of the tubular section 13 of the second body 10 of the second mating connector MC2' can be provided with the two stops 440 that project in the Z direction. The two stops 440 comprise a first stop 440 on the X-direction side and a second stop 440 on the X'-direction side. In the locked state, the first stop 440 is located relative to the handle 610b of the lever body 610 on the Y'-direction side and rests against the handle 610b from the Y'-direction side.In the unlocked state, the second stop 440 is located relative to the handle 610b of the lever body 610 on the Y'-direction side and rests against the handle 610b from the Y'-direction side. Thus, the two stops 440 define the rotation range of the rotary lever 600. The two stops 440 and / or the locking projections 450 can be omitted.

[0312] The first connector part FC1 of connector FC' and the first mating connector MC1 of connection structure CB2 can be connected to each other in a similar way as in the non-restrictive methods described above for connecting the first connector part FC1 of floating connector FC and the first mating connector MC1 in connection structure CB1.

[0313] The second connector part FC2' of connector FC' and the second mating connector MC2' of connection structure CB2 can be connected to each other in a similar manner to the non-restrictive procedures described above for connecting the second connector part FC2 of floating connector FC and the second mating connector MC2 of connection structure CB1, except for the steps below.

[0314] When the second connector part FC2' is connected to the second mating connector MC2' from the Y'-direction side in the second connection state, the abutment 14 is received from the opening 613a of the locking groove 613 through the first chamber 613e1 of the insertion section 613e into the second chamber 613e2 of the insertion section 613e. In the second connection state, rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the second chamber 613e2 towards the deep section 613b or the intermediate section 613f in the locking groove 613. At this point, the abutment 14 is not pressed from the Y'-direction side against the outer circumferential surface 613d of the locking groove 613, but when the abutment 14 has reached the deep section 613b or the intermediate section 613f, the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613.Alternatively, the abutment 14 is not pressed against the outer circumferential surface 613d of the locking groove 613 while moving relative to a point between the second space 613e2 and the deep section 613b or the intermediate section 613f, but the abutment 14 rests against the outer circumferential surface 613d of the locking groove 613 after passing the point, until it reaches the deep section 613b or the intermediate section.

[0315] When the second connector part FC2' is connected to the second mating connector MC2' from the Y'-direction side in a semi-connected state, the abutment 14 is at least partially received by the opening 613a into the first chamber 613e1 of the insertion section 613e. In this semi-connected state, rotation when the rotary lever 600 is turned from the unlocked position to the locked position causes the abutment 14 to move relative to the first chamber 613e1 towards the deep section 613b or the intermediate section 613f in the locking groove 613 and is also pressed from the Y'-direction side against the outer circumferential surface 613d of the locking groove 613.Thus, the second connector part FC2' is moved relative to the second mating connector MC2' in the Y direction, and the second connector part FC2' is transferred from the half-connected state to the second connection state (the fully connected state) with respect to the second mating connector MC2'.

[0316] The FC' connector described above provides the following technical features and effects.

[0317] By rotating the rotary lever 600 of the second mating connector MC2' to press the abutment 14 of the second connector part FC2' of connector FC' from the Y'-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and moving the second connector part FC2' relative to the second mating connector MC2' in the Y-direction, the second connector part FC2' is inserted fully into the second mating connector MC2 and mechanically fully connected to it in a similar manner to how the second connector part FC2, in the half-inserted state with respect to the second mating connector MC2, is fully inserted into the second mating connector MC2 and mechanically fully connected to it.and the second connector part FC2' is also fully electrically connected to the second mating connector MC2' in one of the ways described below.

[0318] Even in a state where the second connector part FC2' is half connected to the second mating connector MC2' from the Y' direction side, the abutment 14 of the second connector part FC2' is at least partially received by the opening 613a of the locking groove 613 of the rotary lever 600 of the second mating connector MC2' into the first space 613e1 of the insertion section 613e of the locking groove 613.

[0319] In the semi-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2' slide onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2' at a distance in the Y-Y' direction that is less than a predetermined distance, and are in contact with the respective second contact sections 21, the outer circumferential surface 613d of the locking groove 613 pushes the abutment 14 from the Y'-direction side to move the second connector part FC2' relative to the second mating connector MC2' in the Y direction such that the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2' are in contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2' by the remaining distance of the predetermined distance. glide.

[0320] In the semi-connected state, when the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2' are not in contact with the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2', the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 of the second mating connector MC2' pushes the abutment 14 of the connector part FC2' from the Y'-direction side to move the second connector part FC2' relative to the second mating connector MC2' in the Y direction, such that the second contact sections 210b of the plurality of terminals 200 of the second connector part FC2' slide onto the respective second contact sections 21 of the plurality of second terminals 20 of the second mating connector MC2' at the predetermined distance, such that the state,in which the multitude of second connections 20 are in contact with the respective second contact sections 21 is maintained.

[0321] Furthermore, if the linear distance D from the second end of the first wall surface 613a1 to the second end of the second wall surface 613a2 of the locking groove 613 is greater than the dimension d' in the YY' direction of the abutment 14, the linear distance d from the first end to the second end of the third wall surface 613b1 of the locking groove 613 is smaller than the linear distance D, and the linear distance from the inner circumferential surface 613c to the outer circumferential surface 613d in the normal direction of the inner circumferential surface 613c of the locking groove 613 gradually decreases from the second end of the first wall surface 613a1 to the second end of the third wall surface 613b1, it is possible by rotating the rotary lever 600,The abutment 14 of the second connector part FC2' is pressed from the Y'-direction side against the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600, and the second connector part FC2' of the connector FC is moved appropriately in the Y direction relative to the second mating connector MC2'. Furthermore, if the linear distance d is equal to, or slightly larger than, the dimension d', it is possible by rotating the rotary lever 600 to move the abutment 14 from the opening 613a into the deep section 613b in the locking groove 613 of the rotary lever 600 and to hold the abutment 14 in the deep section 613b.

[0322] If the central axis of the inner circumferential surface 613c of the locking groove 613 coincides with the axis of rotation P1, but the central axis P2 of the outer circumferential surface 613d of the locking groove 613 is offset by the linear distance D1 from the axis of rotation P1 in the direction of the opening 613a (to the Y-direction side in the unlocked state), it is possible by rotating the rotary lever 600 to press the abutment 14 of the second connector part FC2' from the Y'-direction side with the outer circumferential surface 613d of the locking groove 613 of the rotary lever 600 and to move the second connector part FC2' of the connector FC' appropriately in the Y-direction relative to the second mating connector MC2', while it is difficult for the abutment 14 of the second connector part FC2' moving in the locking groove 613 to align the inner circumferential surface 613c to contact the locking groove 613 or to slide on it.

[0323] The above-described connection structure CB2, which includes the above-described connector FC', provides similar technical features and effects to those of the above-described connector FC'.

[0324] It should be noted that the connector, the first mating connector, the second mating connector, and the connection structure (combination) described above are not limited to the embodiments described above, but can be modified in any way within the scope of the claims. Some examples of modifications are now described.

[0325] The first retainable section 220a of the at least one connection 200 described above only needs to be retained in the first body 100a. For example, the first retainable section 220a of the at least one connection 200 can be overmolded in and retained by the first body 100a. Similarly, the first retainable section 22 of the at least one first connection 20 of the first mating connector MC1 only needs to be retained in the first body 10 and can be overmolded in and retained by the first body 10.
