Description

Technical Field

[0001] The present invention relates to a connector.

Background Art

[0002] In a connector structure that is electrically connected by a pair of connectors (hereinafter, the pair of connectors are referred to as a "connector" and a "counterpart connector"), generally, the connector and the counterpart connector are assembled to each other by fitting in the fitting direction, and the terminals of the connector and the counterpart terminals of the counterpart connector are electrically connected. If an attempt is made to force the counterpart connector to fit into the connector, the connector may move from the normal fitting position and cause internal distortion within the connector structure. Also, if an attempt is made to force the counterpart connector to fit into the connector, even if the connector does not move from the normal fitting position, the counterpart connector may be fitted to the connector with internal stress applied to the connection portion of the connector. For example, when the terminals of the connector are connected to a substrate by solder on the side opposite to the side that fits with the counterpart connector, such distortion or stress may cause cracks in the solder. In this case, the connection reliability of the connector structure decreases.

[0003] Patent Document 1 discloses a connector structure in which when a mating connector is fitted to the connector, the connector can move in a direction perpendicular to the fitting direction from a normal fitting position. In Patent Document 1, the connector includes a connector portion that is electrically connected to the mating connector and a support portion that supports the connector portion. The support portion is disposed on the back side of the connector portion in the fitting direction, and has, in this order from the back side, a holder that is connected to the connector portion and a base member that supports the holder by engagement. A spring that elastically deforms in the fitting direction is provided between the holder and the base member. In Patent Document 1, when the mating connector is fitted to the connector and electrically connected, the spring elastically deforms in the fitting direction, thereby releasing the engagement between the holder and the base member. As a result, the holder can move relative to the base member in a direction perpendicular to the fitting direction, and the connector portion connected to the holder can also move in conjunction with the holder. According to the connector of Patent Document 1, when the connector moves in a direction perpendicular to the fitting direction from a normal fitting position, the generation of internal stress and internal strain within the connector structure is suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] On the side opposite to the side that fits with the mating connector, the wiring portion (for example, an electric wire or a wiring on a printed circuit board) connected to the terminals of the connector is generally led out from the back side of the connector from the viewpoints of electrical characteristics with respect to the transmission path within the connector structure and requirements for narrowing the width of the connector structure. However, in the connector structure of Patent Document 1, since the back side of the connector portion is blocked by the base member of the support portion, it becomes difficult to lead out the wiring from the back side of the connector. Therefore, in the connector structure of Patent Document 1, it becomes difficult to satisfy the requirements for these connectors.

[0006] Therefore, in view of such problems, an object of the present invention is to provide a connector that can easily lead out a wiring portion from the back side while suppressing the load caused by the assembly of a mating connector.

Means for Solving the Problems

[0007] A connector according to an embodiment of the present invention is a connector to which a mating connector is assembled in a first direction, the connector having a front surface on one side in the first direction and a back surface opposite to the front surface, and including a connector body provided with a terminal that is electrically connected to a mating terminal of the mating connector on the front side, and a guide member that holds the connector body movably in at least one of a first direction, a second direction intersecting the first direction, and a third direction intersecting the first direction and the second direction. The terminal has a connection portion electrically connected to a wiring portion, and the guide member is provided at a position where the wiring portion can be led out from the connection portion to the back side.

[0008] The guide member includes a detachment prevention portion that prevents the connector body from detaching from the guide member, the detachment prevention portion having a guide portion, and the connector body may have a guided portion guided by the guide portion.

[0009] The connector further includes a biasing member, the connector body having a main body side housing portion that houses a part of the biasing member, the guide member being provided so as to face the main body side housing portion, the guide member having a guide member side housing portion that houses a part of the biasing member, the biasing member being arranged so as to straddle the main body side housing portion and the guide member side housing portion, and when the connector body moves from a predetermined position with respect to the guide member, the biasing member may bias the connector body in a direction opposite to the direction in which the connector body has moved so that the connector body returns to the predetermined position.

[0010] The biasing member is composed of a single elastically deformable spring. The main body side accommodating portion and the guide member side accommodating portion each have an opposing wall facing the end of the spring. At least one of the main body side accommodating portion and the guide member side accommodating portion may protrude from the opposing wall and have a retaining portion that engages with the spring.

Advantages of the Invention

[0011] According to the connector according to an embodiment of the present invention, while suppressing the load caused by the assembly of the mating connector, it becomes easier to lead out the wiring portion from the back side.

[0013] Hereinafter, with reference to the accompanying drawings, a connector according to an embodiment of the present invention will be described. Note that the following embodiments are merely examples, and the connector of the present invention is not limited to the following embodiments. In this specification, expressions such as "perpendicular to A" and the like do not refer only to a direction completely perpendicular to A, but include a direction substantially perpendicular to A. Also, in this specification, expressions such as "parallel to B" and the like do not refer only to a direction completely parallel to B, but include a direction substantially parallel to B. Further, in this specification, expressions such as "C shape" and the like do not refer only to a complete C shape, but include a shape that reminds one of a C shape, such as a shape in which the corners of the C shape are chamfered (substantially C shape).

[0014] [Connector Structure According to the Present Embodiment] FIGS. 1A and 1B show a connector structure C including a connector 1 according to the present embodiment and a mating connector A. In the present embodiment, the connector structure C is a connector structure including a pair of connectors 1 and A. The connector structure C includes, as a pair of connectors 1 and A, a connector 1 which is one of the pair of connectors 1 and A, and a mating connector A which is the other of the pair of connectors 1 and A.

[0015] In this specification, the direction in which the mating connector A is assembled to the connector 1 is referred to as the first direction D1. Here, in this specification, the terms "assembly" and similar expressions refer to a use state in which the connector 1 and the mating connector A are electrically connected, for example, by fitting. The first direction D1 refers to the direction in which the mating connector A faces the connector 1 in this use state. Therefore, for example, when the mating connector A is connected to the connector 1, if the mating connector A is inserted into the connector 1 in a posture inclined with respect to the posture in the final use state, and then the mating connector A changes its posture with respect to the connector 1 and then moves in the X direction toward the connector 1 to reach the final use state, etc., when the posture between the mating connector A and the connector 1 changes during the fitting process, the X direction becomes the first direction D1. Note that "assembly" is not limited to assembly by fitting, and may be other types of assembly, such as assembly by screwing. In this embodiment, the first direction D1 is the same direction as the extending direction of the terminal T1 of the connector 1. In this specification, among the first direction D1, the direction in which the mating connector A is assembled to the connector 1 is referred to as the assembly direction D11, and the direction in which the mating connector A assembled to the connector 1 is removed from the connector 1 is referred to as the detachment direction D12. Also, in this specification, one of the directions intersecting the first direction D1 is referred to as the second direction D2. In this embodiment, the second direction D2 is one of the directions perpendicular to the first direction D1. In this embodiment, the second direction D2 is the same direction as the direction in which a plurality of terminals T1 of the connector 1 are arranged. Further, in this specification, the direction intersecting both the first direction D1 and the second direction D2 is referred to as the third direction D3. In this embodiment, as will be described later, the third direction D3 is the direction in which the guide member 3 is provided with respect to the connector body 2, and more specifically, it is the direction perpendicular to both the first direction D1 and the second direction D2.

[0016] In the connector structure C shown in FIGS. 1A and 1B, when the mating connector A fits into the connector 1 from the assembling direction D11, the mating connector A is electrically connected to the connector 1. When the mating connector A that is fitted to the connector 1 detaches from the connector 1 in the detachment direction D12, the electrical connection between the mating connector A and the connector 1 is released. Here, in this specification, the "assembling direction D11" refers to the direction in which the connector 1 and the mating connector A approach each other when they are electrically connected, and the "detachment direction D12" refers to the direction in which the connector 1 and the mating connector A move away from each other when they are electrically connected. That is, in this specification, the expression "the mating connector A is assembled to the connector 1 from the assembling direction D11" and similar expressions include the case where the position of the connector 1 is fixed and the mating connector A moves closer to the connector 1, the case where the position of the mating connector A is fixed and the connector 1 moves closer to the mating connector A, and the case where both the connector 1 and the mating connector A move in a direction approaching each other. Similarly, in this specification, the expression "the mating connector A detaches from the connector 1 in the detachment direction D12" and similar expressions include the case where the position of the connector 1 is fixed and the mating connector A moves away from the connector 1, the case where the position of the mating connector A is fixed and the connector 1 moves away from the mating connector A, and the case where both the connector 1 and the mating connector A move in a direction moving away from each other. In other words, the expression "the mating connector A is assembled to the connector 1 in the first direction D1" and similar expressions include the case where the mating connector A moves in the first direction D1 (specifically, the assembling direction D11), the case where the connector 1 moves in the first direction D1 (specifically, the assembling direction D11), and the case where both the connector 1 and the mating connector A move in the first direction D1 (specifically, the assembling direction D11). In the attached drawings, it is assumed that the position of the connector 1 is fixed and the mating connector A approaches the connector 1. The assembling direction D11 is shown as the direction for assembling the mating connector A to the connector 1, and the detachment direction D12 is shown as the direction for removing the mating connector A assembled to the connector 1 from the connector 1.

[0017] The use of the connector structure C is not particularly limited. In this embodiment, the connector structure C is used to electrically connect between a terminal body of a portable information processing terminal such as a notebook personal computer and a battery assembly such as a rechargeable battery pack connected to the terminal body. Specifically, the connector 1 is attached to a first housing H1 such as a housing of the terminal body, and the mating connector A is attached to a second housing H2 such as a housing of the battery assembly connected to the first housing H1. However, the connector structure C may be used to connect between other electrical devices.

[0018] The mode of the connector structure C is not particularly limited, but in this embodiment, the connector 1 is a male connector and the mating connector A is a female connector. However, the genders of the connector 1 and the mating connector A are not particularly limited, and the connector 1 may be a female connector and the mating connector A may be a male connector. In this embodiment, the terminal T1 of the connector 1 is electrically connected to the wiring portion W1, and the mating terminal T2 of the mating connector A is electrically connected to the mating wiring portion W2.

[0019] The wiring portion W1 electrically connects the connection target on the connector 1 side and the connector 1. The counterpart wiring portion W2 electrically connects the connection target on the counterpart connector A side and the counterpart connector. In FIGS. 1A and 1B, the wiring portion W1 is a flexible electric wire (cable), and the counterpart wiring portion W2 is a connection pad (printed circuit) W2 on the surface of the substrate B, which is a wire-to-substrate connector structure. However, the connector structure C may be a board-to-board connector structure in which both the wiring portion W1 and the counterpart wiring portion W2 are connection pads (printed circuits) on the substrate, or may be a wire-to-wire connector structure in which both the wiring portion W1 and the counterpart wiring portion W2 are flexible electric wires. Note that the connector structure C may be a board edge type connector structure in which the counterpart terminal T2 and the counterpart wiring portion W2 are integrated and the counterpart connector A is provided as an end portion of the substrate. In the present embodiment, the connector structure C is a so-called horizontal fitting type connector structure in which the connector 1 and the counterpart connector A are fitted in a direction parallel to the substrate B. However, it may be a so-called vertical fitting type connector structure in which the connector 1 and the counterpart connector A are fitted from a direction perpendicular to the substrate B.

[0020] [Connector according to the present embodiment] As shown in FIGS. 1A and 1B, the connector 1 is electrically connected when the counterpart connector A is assembled in the first direction D1 (specifically, the assembly direction D11), and the electrical connection is released when the counterpart connector A is removed in the first direction D1 (specifically, the removal direction D12). The connector 1 includes a connector body 2 that is electrically connected to the counterpart connector A, and a guide member 3 that movably holds the connector body 2. The arrangement of the connector 1 is not particularly limited, but in the present embodiment, the connector 1 is provided in the first housing H1. In the present embodiment, as shown in FIG. 2, the connector 1 further includes a biasing member 4.

[0021] As shown in FIGS. 1A and 2, the connector body 2 has a front surface (assembly surface with the mating connector A) 2a on one side (assembly direction D11) in the first direction D1 and a back surface 2b opposite to the front surface 2a. The connector body 2 includes a terminal T1 that is electrically connected to the mating terminal T2 (see FIGS. 1A and 1B) of the mating connector A on the front surface 2a side. The connector body 2 is movable with respect to the guide member 3. In the present embodiment, the connector body 2 is held by the guide member 3 at a predetermined position by the biasing force of the biasing member 4 (see FIG. 2). The shape of the connector body 2 is not particularly limited as long as the mating connector A can be assembled and disassembled in the first direction D1. In the present embodiment, the connector body 2 has an elongated shape extending in the second direction D2 so that a plurality of terminals T1 can be arranged at a predetermined interval in the second direction D2 and separated from each other. In the present embodiment, the connector body 2 has a guided portion 211 that is guided by the guide member 3. In the present embodiment, the connector body 2 further has an engaged portion 212 that engages with the guide member 3. Further, in the present embodiment, the connector body 2 has a main body side accommodating portion 22 that accommodates a part of the biasing member 4. The connector body 2 may have an assembly guide portion 23 that guides the assembly of the connector 1 and the mating connector A.

[0022] As shown in FIGS. 1A and 1B, terminal T1 electrically connects mating connector A and wiring portion W1. In FIG. 1A, terminal T1 protrudes from front surface 2a of connector body 2. More specifically, terminal T1 protrudes from front surface 2a of connector body 2 along first direction D1. In the present embodiment, as shown in FIG. 2, terminal T1 has contact portion T11 that is electrically connected to mating connector A. Also, in the present embodiment, terminal T1 has connection portion T12 that is electrically connected to wiring portion W1. Specifically, contact portion T11 is provided on the front surface 2a side (detachment direction D12 side in FIG. 2) of connector body 2 so that mating terminal T2 is electrically connected from the front surface 2a side of connector body 2, and connection portion T12 is provided on the back surface 2b side (assembly direction D11 side in FIG. 2) of connector body 2 so that wiring portion W1 is led out from the back surface 2b side of connector body 2. In FIG. 2, terminal T1 has a linear shape extending in first direction D1. However, terminal T1 may have other shapes, such as a shape that extends while bending from the front surface 2a side to the back surface 2b side. The form of the electrical connection between terminal T1 and mating terminal T2 and the electrical connection between terminal T1 and wiring portion W1 is not particularly limited. In the present embodiment, contact portion T11 is electrically connected to mating terminal T2 by inserting mating terminal T2 externally and contacting mating terminal T2, and connection portion T12 is electrically connected to wiring portion W1 by crimping wiring portion W1. However, the electrical connection between terminal T1 and mating terminal T2 and the electrical connection between terminal T1 and wiring portion W1 may be in other forms. The number and arrangement of terminals T1 are not particularly limited. In the present embodiment, a plurality of types of terminals T1 are spaced apart from each other at a predetermined interval in second direction D2, and a plurality of each (in FIG. 2, from the back of the paper, there are 2 large-sized terminals, 5 small-sized terminals, and 2 medium-sized terminals) are arranged. However, the number and arrangement of terminals T1 can be appropriately changed according to the number and arrangement of mating terminal T2 (see FIGS. 1A and 1B), which is the connection partner.

[0023] The guided portion 211 is guided by a guide member 3 (specifically, a guide portion 311 described later) in at least one of a first direction D1, a second direction D2, and a third direction D3, as shown in the perspective view of FIG. 2 and the cross-sectional view (a cross-sectional view taken along line VA-VA of FIG. 3) shown in FIG. 5A. In the present embodiment, the guided portion 211 is guided by the guide portion 311 in at least the second direction D2. The shape and arrangement of the guided portion 211 are not particularly limited as long as it is guided in a predetermined direction by the guide portion 311. In the present embodiment, as shown in FIG. 2, the guided portion 211 is constituted by a guided surface (a surface including the second direction D2 and the third direction D3) that extends along the second direction D2 in parallel with the guide portion 311. Further, in the present embodiment, it is provided at both ends of the connector body 2 in the second direction D2. In this case, since the guided portion 211 does not interfere with the arrangement of the terminals T1 inside the connector body 2, the degree of freedom in arranging the terminals T1 increases. Further, in the present embodiment, the guided portion 211 is provided on a protruding portion 21 that protrudes outward in the second direction D2 from a side surface 2e (more specifically, both side surfaces 2e). Specifically, the guided portion 211 is constituted by a side surface of the protruding portion 21 facing the first direction D1. By providing the engaged portion 212 on the protruding portion 21, the guided portion 211 can be obtained with a simple structure. In FIG. 2, the guided portion 211 is constituted by inner surfaces of a pair of protruding portions 21 that are spaced apart in the first direction D1 (the assembly direction D11 side and the detachment direction D12 side) and face each other. In this case, if the guided portion 211 is arranged so as to sandwich the guide portion 311 in the second direction D2, the movement of the guided portion 211 in the first direction D1 can be restricted and the guided portion 211 can be more stably guided in the second direction D2 by the guide portion 311. However, the shape and arrangement of the guided portion 211 can be appropriately changed according to the shape and arrangement of the guide portion 311 by which the guided portion 211 is guided. The guiding by the guided portion 211 and the guide portion 311 will be described later.

[0024] As shown in FIG. 4A, the engaged portion 212 engages with the guide member 3 (specifically, the engaging portion 312 of the detachment prevention portion 31 described later) so that the connector body 2 does not detach from the guide member 3. In the present embodiment, the engaged portion 212 engages with the guide member 3 in the third direction D3 so that the connector body 2 does not detach from the guide member 3 in the third direction D3. The shape and arrangement of the engaged portion 212 are not particularly limited as long as it can engage with the engaging portion 312. In the present embodiment, as shown in FIG. 2, the engaged portions 212 are provided at both ends of the connector body 2 in the second direction D2. In this case, since the engaged portion 212 does not interfere with the arrangement of the terminals T1 inside the connector body 2, the degree of freedom in arranging the terminals T1 increases. Further, in the present embodiment, the engaged portion 212 is provided on the protruding portion 21 in the same manner as the guided portion 211. Specifically, the engaged portion 212 is constituted by the side surface of the protruding portion 21 facing the third direction D3. By providing the engaged portion 212 on the protruding portion 21, the engaged portion 212 can be obtained together with the guided portion 211 with a simple structure. In FIG. 2, the guided portion 211 is constituted by the side surface (the side surface facing away from the guide member 3) of the pair of protruding portions 21 facing one direction in the third direction D3. In this case, the engagement of the engaged portion 212 with the engaging portion 312 becomes stronger due to the engagement at a plurality of positions spaced apart from each other. However, the shape and arrangement of the engaged portion 212 can be appropriately changed according to the shape and arrangement of the engaging portion 312 with which the engaged portion 212 is engaged. Further, the guided portion 211 and the engaged portion 212 may not be integrally provided as a part of the protruding portion 21, respectively, and may be provided separately. The engagement between the engaged portion 212 and the engaging portion 312 will be described later.

[0025] As shown in the perspective view of FIG. 2 and the cross-sectional view (cross-section taken along line VA-VA of FIG. 3) shown in FIG. 5A, the main body side accommodating portion 22 accommodates the biasing member 4 together with the guide member side accommodating portion 32 described later. Specifically, the main body side accommodating portion 22 accommodates a part of the biasing member 4, and more specifically, accommodates approximately half of the biasing member 4. In the present embodiment, the main body side accommodating portion 22 is provided as a concave portion on the opposing surface 2c of the connector main body 2 with the guide member 3. Specifically, the main body side accommodating portion 22 is provided so as to be recessed in a semi-cylindrical shape from the opposing surface 2c in the third direction D3. Further, in the present embodiment, the main body side accommodating portion 22 has opposing walls 22a and 22b that oppose the ends of the spring constituting the biasing member 4. Specifically, the opposing walls 22a and 22b oppose the ends 4a and 4b of the spring (biasing member) 4 in the second direction D2, which is the expansion and contraction direction of the spring (biasing member) 4. In the present embodiment, the main body side accommodating portion 22 is provided in the central region of the connector main body 2 in the second direction D2 (more specifically, at a position closer to one side in the second direction D2 in the central region). The main body side accommodating portion 22 can be provided at a position that coincides with the assembly guide portion 23 where the terminal T1 is not provided in the second direction D2. In this case, within the limited size of the connector main body 2, the main body side accommodating portion 22 can be provided so as not to interfere with the arrangement of the terminal T1.

[0026] In the present embodiment, as shown in FIG. 5A, the main body side accommodating portion 22 has a retaining portion G that protrudes in the second direction D2 from the opposing walls 22a and 22b and engages with the spring (biasing member) 4. The engagement between the spring (biasing member) 4 and the retaining portion G prevents the spring (biasing member) 4 from detaching from the connector main body 2. Specifically, the retaining portion G is constituted by convex portions that protrude in the second direction D2 from the opposing walls 22a and 22b, and engages with the inner surface of the biasing member 4 constituted by a coil spring. However, when the guide member side accommodating portion 32 described later has the retaining portion G, the main body side accommodating portion 22 does not necessarily have to have the retaining portion G.

[0027] As shown in FIGS. 1A and 1B, the assembly guide portion 23 guides the mating connector A in the first direction D1 so that the mating connector A is assembled to the connector 1. In the present embodiment, the assembly guide portion 23 is provided as a convex portion that protrudes in the first direction D1 from the front surface 2a of the connector body 2 (in FIGS. 1A and 1B, in the front surface 2a, in the central region in the second direction D2 (more specifically, at a position closer to one side in the second direction D2 in the central region)). Further, in the present embodiment, the mating connector A has a mating assembly guide portion A2 provided as a concave portion corresponding to the shape of the assembly guide portion 23 that is recessed in the first direction D1 from the mating assembly surface A1 (the surface facing the front surface 2a of the connector 1). In this way, when the mating connector A is assembled to the connector 1, the mating assembly guide portion A2 fits into the assembly guide portion 23, so that the mating connector A can be guided in the first direction D1 while restraining movement in the second direction D2.

[0028] In the present embodiment, the protruding amount of the assembly guide portion 23 from the front surface 2a in the first direction D1 is larger than that of the terminal T1. In this case, when the mating connector A is assembled to the connector 1, after the assembly guide portion 23 abuts against the mating assembly guide portion A2, the terminal T1 abuts against the mating terminal T2. Therefore, the impact at the time of abutment between the terminal T1 and the mating terminal T2 after this is alleviated by the abutment between the assembly guide portion 23 and the mating assembly guide portion A2, and damage due to the abutment between the terminal T1 and the mating terminal T2 is suppressed.

[0029] As shown in FIGS. 1A and 1B, the guide member 3 holds the connector body 2 so as to be movable in at least one of a first direction D1, a second direction D2, and a third direction D3. In the present embodiment, the guide member 3 holds the connector body 2 so as to be movable in at least the second direction D2. More specifically, the guide member 3 holds the connector body 2 so as to be movable in the second direction D2 while restraining the connector body 2 in the first direction D1 and the third direction D3. However, the guide member 3 may hold the connector body 2 so as to be movable in the third direction D3 while restraining the connector body 2 in the first direction D1 and the second direction D2, or may hold the connector body 2 so as to be movable in the first direction D1 while restraining the connector body 2 in the second direction D2 and the third direction D3. Further, the guide member 3 may hold the connector body 2 so as to be movable in the second direction D2 and the third direction D3 while restraining the connector body 2 in the first direction D1, or may hold the connector body 2 so as to be movable in the first direction D1 and the third direction D3 while restraining the connector body 2 in the second direction D2, or may hold the connector body 2 so as to be movable in the first direction D1 and the first direction D1 while restraining the connector body 2 in the third direction D3. When the guide member 3 holds the connector body 2 so as to be movable in the first direction D1, the impact during the assembly of the connector 1 and the mating connector A can be mitigated. When the guide member 3 holds the connector body 2 so as to be movable in the second direction D2 and / or the third direction D3, internal strain and internal stress in the connector structure C generated when the mating connector A is forcibly fitted to the connector 1 are suppressed.

[0030] As shown in FIGS. 1A and 1B, the guide member 3 is provided at a position where the wiring portion W1 can be led out from the connection portion T12 (see FIG. 2) to the back surface 2b side of the connector body 2. When the wiring portion W1 is led out from the back surface 2b side of the connector body 2, the terminals T1 and the wiring W1 can be made linear. Even if the terminals T1 and the wiring W1 are not linear, for example, compared with the case where the wiring W1 is led out from the side surface 2e side facing the second direction D2 of the connector body 2, the bending of the terminals T1 and the wiring W1 can be reduced. Therefore, the deterioration of the electrical characteristics of the transmission path in the connector structure C due to the bending of the terminals T1 and the wiring W1 and the increase in the size of the connector structure C are suppressed. In the present embodiment, as shown in FIG. 2, the guide member 3 is provided so as to face at least one of the side surfaces 2c, 2d, 2e of the connector body 2 facing the second direction D2 and the third direction D3 so as not to block the front surface 2a and the back surface 2b of the connector body 2. Specifically, the guide member 3 is provided so as to face the connector body 2 in the third direction D3 (specifically, one of the third directions D3), and the wiring portion W1 is led out from the connection portion T12 to the back surface 2b side of the connector body 2 not blocked by the guide member 3. In FIGS. 1A and 1B, the guide member 3 is provided as a separate body from the first housing H1 on one side of the third direction D3 with respect to the connector body 2. Also, in FIGS. 1A and 1B, the guide member 3 is fixed to the connector body 2 and the first housing H1 by a known fixture F such as a screw at the surface 3d (mounting surface) opposite to the facing surface 3c (see FIG. 1A) with the connector body 2. However, the guide member 3 may be provided integrally with the first housing H1 as a part of the first housing H1. Also, the arrangement of the guide member 3 is not particularly limited as long as the wiring portion W1 can be led out from the connection portion T12 to the back surface 2b side of the connector body 2, and the guide member 3 may be arranged at other positions, such as being provided on both sides of the third direction D3 with respect to the connector body 2 (both surfaces 2c, 2d facing the third direction D3 of the connector body 2).

[0031] In this embodiment, as shown in FIG. 2, when holding the connector body 2, the guide member 3 has a C-shaped opening in one direction of the third direction D3 as viewed from the first direction D1 so as not to block the front surface 2a and the back surface 2b of the connector body 2. Specifically, the guide member 3 includes a plate-shaped base portion 33 extending in the second direction D2, and standing portions 34 standing in the third direction D3 from both ends of the base portion in the second direction D2. As shown in FIG. 1A, the guide member 3 is fixed to the first housing H1 by inserting the fixture F through the standing portion 34 in the third direction D3. However, the guide member 3 may have other shapes, for example, it may be composed of two members separately provided at both ends in the second direction D2.

[0032] In this embodiment, as shown in FIG. 2, the guide member 3 has a detachment prevention portion 31 for preventing the connector body 2 from detaching from the guide member 3. Further, in this embodiment, the guide member 3 is provided so as to face the main body side housing portion 22, and has a guide member side housing portion 32 for housing a part of the biasing member 4.

[0033] The detachment prevention portion 31 holds the connector body 2 so as to prevent the connector body 2 from detaching from the guide member 3. In this embodiment, as shown in FIG. 2, the detachment prevention portion 31 has an engaging portion 312 that engages with the connector body 2. Specifically, the engaging portion 312 engages with the engaged portion 212 of the connector body 2 in the third direction D3, thereby preventing the connector body 2 from detaching in the third direction D3. For example, as shown in FIG. 2, the engaging portion 312 can be constituted by an opposing surface that faces the engaged portion 212 in a direction for preventing the connector body 2 from detaching from the guide member 3. In this embodiment, the engaging portion 312 is constituted by an opposing surface that faces the engaged portion 212 in the third direction D3.

[0034] In this embodiment, the detachment prevention unit 31 not only prevents the connector body 2 from detaching from the guide member 3 of the connector body 2, but also holds the connector body 2 so that the connector body 2 is movable relative to the guide member 3 in a predetermined direction. To exhibit such a function, in this embodiment, as shown in FIG. 2, the detachment prevention unit 31 has a guide portion 311 that guides the connector body 2. Specifically, the guide portion 311 contacts the guided portion 211 of the connector body 2 in the first direction D1, thereby restraining the connector body 2 in the first direction D1 and enabling the guided portion 211 to slide in the second direction D2, so as to guide the connector body 2 in the second direction D2. The guide portion 311 can be constituted by, for example, as shown in FIG. 2, the opposing surface with the guided portion 211 extending in the second direction D2 so as to guide the guided portion 211. In this embodiment, the guide portion 311 is constituted by the opposing surface that faces the guided portion 211 in the first direction D1.

[0035] The shape and arrangement of the detachment prevention portion 31 are not particularly limited as long as they can prevent detachment from the guide member 3 of the connector body 2. In the present embodiment, the detachment prevention portion 31 is provided as a protruding portion that protrudes inward in the second direction D2 from the inner surface (more specifically, both inner surfaces) of the standing portion 34. Specifically, as shown in FIG. 2, the detachment prevention portion 31 is provided as a protruding portion having a T shape when viewed from the second direction D2. More specifically, the detachment prevention portion 31 has, at both ends in the second direction D2, a second direction extension portion 31a that extends in the third direction D3 from the facing surface 3c of the guide member 3 with the connector body 2, and a first direction extension portion 31b that branches from the tip of the second direction extension portion 31a and extends in both directions of the first direction D1. In FIG. 2, the guide portion 311 is configured by both side surfaces of the second direction extension portion 31a facing the outside of the second direction extension portion 31a in the first direction D1, and contacts the guided portion 211 configured by the inner surface of the protruding portion 21 in the first direction D1 to guide the connector body 2 in the second direction D2. Also, in FIG. 2, the engaging portion 312 is configured by the side surface of the first direction extension portion 31b facing the facing surface 3c of the guide member 3 in the third direction D3, and engages with the engaged portion 212 configured by the side surface of the protruding portion 21 in the third direction D3 to restrain the connector body 2 in the third direction D3. However, the shape and arrangement of the detachment prevention portion 31 can be appropriately changed according to the shape and arrangement of the guided portion 211 of the connector body 2 and the like.

[0036] As shown in FIG. 2, the guide member side housing portion 32, together with the main body side housing portion 22, houses the biasing member 4. Specifically, the guide member side housing portion 32 houses a part of the biasing member 4, and more specifically, houses approximately half of the biasing member 4. In the present embodiment, the guide member side housing portion 32 is provided as a concave portion on the facing surface 3c of the guide member 3 with respect to the connector main body 2. Specifically, the guide member side housing portion 32 is provided so as to be recessed in a semi-cylindrical shape from the facing surface 3c in the third direction D3. Further, in the present embodiment, the guide member side housing portion 32 has opposing walls 32a and 32b that face the ends of the biasing member 4 (a spring in the present embodiment). Specifically, the opposing walls 32a and 32b face the ends 4a and 4b of the spring (biasing member) 4 in the second direction D2, which is the expansion and contraction direction of the spring (biasing member) 4. In the present embodiment, the guide member side housing portion 32 is provided in the central region of the guide member 3 in the second direction D2 (more specifically, at a position closer to one side in the second direction D2 in the central region). The guide member side housing portion 32 can be provided at a position facing the main body side housing portion 22 in the third direction D3 when the connector main body 2 is located at a predetermined position.

[0037] In the present embodiment, as shown in FIG. 5A, the opposing walls 32a and 32b of the guide member side housing portion 32 are set to be flush with the opposing walls 22a and 22b of the main body side housing portion 22 when the connector main body 2 is located at a predetermined position. In this case, since it becomes difficult for the spring (biasing member) 4 to deform unevenly between the portion housed in the main body side housing portion 22 and the portion housed in the guide member side housing portion 32, the restoring force of the spring (biasing member) 4 that tries to return the connector main body 2 to the predetermined position acts easily on both the opposing walls 32a and 32b of the guide member side housing portion 32 where the ends 4a and 4b of the spring (biasing member) 4 abut and the opposing walls 22a and 22b of the main body side housing portion 22. However, the opposing walls 32a and 32b of the guide member side housing portion 32 do not necessarily have to be flush with the opposing walls 22a and 22b of the main body side housing portion 22 when the connector main body 2 is located at a predetermined position.

[0038] In this embodiment, as shown in FIG. 5A, the dimension (depth of the recess) of the guide member side accommodating portion 32 in the third direction D3 is smaller than that of the main body side accommodating portion 22. In this embodiment, since the connector main body 2 has a dimension capable of accommodating the terminal T1 (see FIGS. 1A and 2), the dimension in the third direction D3 is larger than that of the guide member 3. In such a case, by providing the main body side accommodating portion 22 having a dimension in the third direction D3 larger than that of the guide member side accommodating portion 32 on the connector main body 2 side, the limited size of the connector 1 can be effectively utilized, and thus the overall thickness of the connector 1 can be reduced. Further, in this embodiment, as described above, the retaining portion G is provided on the connector main body 2. When manufacturing the connector 1 from the connector main body 2, the guide member 3, and the biasing member 4, the spring (biasing member) 4 is engaged with the retaining portion G, and then the connector main body 2 is assembled to the guide member 3. In such a case, if the dimension of the main body side accommodating portion 22 in the third direction D3 is larger than that of the guide member side accommodating portion 32, the connector main body 2 can be assembled to the guide member 3 with most of the spring (biasing member) 4 accommodated in the main body side accommodating portion 22. By doing so, when the connector main body 2 and the guide member 3 are assembled, the spring (biasing member) 4 contracts due to contact with the opposing walls 22a and 22b of the main body side accommodating portion 22 on the side where it is accommodated in the main body side accommodating portion 22, while on the side not accommodated in the main body side accommodating portion 22 (the side to be accommodated in the guide member side accommodating portion 32), it expands and spreads, suppressing a situation where it becomes difficult to accommodate in the guide member side accommodating portion 32. However, the dimension (depth of the recess) of the guide member side accommodating portion 32 in the third direction D3 may be equal to that of the main body side accommodating portion 22. In this case, in the third direction D3, the spring (biasing member) 4 is evenly accommodated in the main body side accommodating portion 22 and the guide member side accommodating portion 32, and the elastic force of the spring (biasing member) 4 is likely to be uniformly applied to the main body side accommodating portion 22 and the guide member side accommodating portion 32, so that the restoring force of the spring (biasing member) 4 for returning the connector main body 2 to a predetermined position easily acts. Further, the dimension (depth of the recess) of the guide member side accommodating portion 32 in the third direction D3 may be larger than that of the main body side accommodating portion 22.

[0039] In this embodiment, as shown in FIGS. 5A to 5C, when the connector body 2 moves from a predetermined position (FIG. 5A) to (FIG. 5B or FIG. 5C) with respect to the guide member 3, the biasing member 4 biases the connector body 2 in the direction opposite to the moving direction of the connector body 2 so that the connector body 2 returns to the predetermined position (FIG. 5A). In this embodiment, the "predetermined position" of the connector body 2 is, for example, the position (initial position) where the connector body 2 is located with respect to the guide member 3 when the mating connector A is assembled to the connector 1 without difficulty as designed. Specifically, the "predetermined position" is the position where the bisector of the guide member 3 and the bisector of the connector body 2 overlap in the second direction D2, and more specifically, it is the central position of the movable range of the connector body 2 with respect to the guide member 3 (more specifically, the movable range in the second direction D2). However, the "predetermined position" is not particularly limited as long as there is no problem in assembling the connector 1 and the mating connector A.

[0040] The form of the biasing member 4 is not particularly limited. In this embodiment, as shown in FIG. 2, the biasing member 4 is constituted by a single elastically deformable spring. More specifically, the biasing member 4 is constituted by a single coil spring that is elastically deformable in the second direction D2. However, the biasing member 4 may be constituted by other members such as stretchable rubber or leaf springs, or may be constituted by a plurality of members (for example, a plurality of springs). In this embodiment, as shown in FIGS. 5A to 5C, when the connector body 2 moves along the second direction D2 from a predetermined position with respect to the guide member 3, the spring (biasing member) 4 elastically deforms by abutting against the opposing walls 32a and 32b of the guide member side accommodating portion 32 to generate an elastic force (restoring force of elastic deformation), and biases the connector body 2 in the direction opposite to the moving direction of the connector body 2 so that the connector body 2 returns to the predetermined position.

[0041] In the present embodiment, as shown in FIG. 5A, the biasing member 4 is disposed so as to straddle the main body side accommodating portion 22 and the guide member side accommodating portion 32. In FIG. 5A, even when the connector main body 2 is located at a predetermined position, the spring (biasing member) 4 is elastically deformed (contracted state) by abutting against the opposing walls 22a and 22b of the main body side accommodating portion 22 and the opposing walls 32a and 32b of the guide member side accommodating portion 32, and is accommodated in the main body side accommodating portion 22 and the guide member side accommodating portion 32. In this case, since an elastic force (restoring force) always acts on the spring (biasing member) 4, it becomes easier to return the connector main body 2 to the predetermined position. However, the spring (biasing member) 4 may be accommodated in a non-elastically deformed state (non-contracted state). In other words, the spring (biasing member) 4 may be accommodated in the main body side accommodating portion 22 and the guide member side accommodating portion 32 in a state where it does not abut against at least one of the opposing walls 22a and 22b of the main body side accommodating portion 22 and the opposing walls 32a and 32b of the guide member side accommodating portion 32 when the connector main body 2 is located at a predetermined position.

[0042] As described above, the biasing member 4 is engaged with the retaining portion G provided in the main body side accommodating portion 22, thereby preventing the disengagement from the connector main body 2 when manufacturing the connector 1. However, at least one of the main body side accommodating portion 22 and the guide member side accommodating portion 32 may have a retaining portion G protruding from the opposing walls 22a, 22b, 32a, 32b, and the spring (biasing member) 4 may be engaged with the retaining portion G provided in at least one of the main body side accommodating portion 22 and the guide member side accommodating portion 32. For example, when the retaining portion G is provided in the guide member side accommodating portion 32, the connector 1 can be manufactured by engaging the spring (biasing member) 4 with the retaining portion G of the guide member side accommodating portion 32 and then assembling the guide member 3 to the connector main body 2.

[0043] [Behavior of the Connector According to the Present Embodiment] Next, the behavior of the connector 1 described above will be described below with reference to FIGS. 1A, 1B, and 3 to 6B. Note that the following description is merely an example, and the behavior of the connector of the present invention is not limited to the following description.

[0044] Figure 4A is a cross-sectional view taken along line IVA-IVA in the top view of the connector 1 shown in FIG. 3, and FIG. 5A is a cross-sectional view taken along line VA-VA in FIG. 3. FIGS. 4A and 5A show cross-sectional views when, for example, the connector body 2 is positioned at a predetermined position with respect to the guide member 3. In the present embodiment, when the mating connector A is assembled to the connector 1 from the normal assembling direction D11 (see FIGS. 1A and 1B), as shown in FIGS. 4A and 5A, the connector 1 is positioned at a predetermined position without relative movement with respect to the mating connector A.

[0045] In the present embodiment, as shown in FIG. 6A, when the mating connector A tries to be assembled to the connector 1 deviating from the normal assembling direction D11 to one D21 (hereinafter, for convenience, referred to as "left direction D21") in the second direction D2 (in FIG. 6A, it deviates by an amount S from the normal assembling direction D11 to the left direction D21), in the second direction D2, the side surfaces of the assembling guide portion 23 and the mating assembling guide portion A2 come into contact with each other, and / or the side surfaces of the terminal T1 of the connector 1 and the mating terminal T2 of the mating connector A come into contact with each other. At this time, as shown in FIG. 4B, by the engagement in the third direction D3 between the engaged portion 212 and the engaging portion 312, while preventing the separation of the connector body 2 from the guide member 3, the guided portion 211 (see FIG. 5B) is guided in the second direction D2 by the guide portion 311, so that, as shown in FIG. 6B, the connector body 2 relatively moves in the left direction D21 with respect to the guide member 3 from a predetermined position (see the broken line of the connector body 2 in FIG. 6B) (see the solid line of the connector body 2 in FIG. 6B). By this relative movement of the connector body 2 with respect to the guide member 3, the force trying to forcibly assemble the connector 1 and the mating connector A can be released in the second direction D2, so that the generation of internal stress and internal strain within the connector structure C is suppressed. Further, even after the connector 1 and the mating connector A are assembled, when an impact is applied to the connector structure C, the impact force can be released in the second direction D2 by the relative movement of the connector body 2 with respect to the guide member 3, so that the impact resistance of the connector structure C is increased.

[0046] During this relative movement in the leftward direction D21, in the present embodiment, as shown in FIG. 5B, the spring (biasing member) 4 is sandwiched between the opposing wall 22b on the other direction D22 (hereinafter, for convenience, referred to as the "rightward direction D22") side of the second direction D2 of the main body side housing portion 22 and the opposing wall 32a on the leftward direction D21 side of the guide member side housing portion 32, and thus elastically deforms so as to contract in the second direction D2. As a result, a restoring force (elastic force) of the spring (biasing member) 4 that biases the connector main body 2 in the rightward direction D22 with respect to the guide member 3 is generated. Therefore, at least when the mating connector A is removed from the connector 1, the connector main body 2 returns to a predetermined position with respect to the guide member 3 (see FIGS. 4A and 5A). In this way, even when the connector main body 2 moves relatively in the leftward direction D21, it returns to a predetermined position by the spring (biasing member) 4. Therefore, when repeatedly assembling and disassembling the mating connector A, the connector 1 does not stay at a position deviated from the predetermined position. Therefore, it is suppressed that the connector 1 is located at a position deviated from the predetermined position, which makes it difficult to assemble the connector 1 and the mating connector A. Note that the connector main body 2 may return to a predetermined position when the mating connector A is assembled to the connector 1 or when the mating connector A has been assembled to the connector 1. In this case, internal stress and internal strain in the connector structure C during or after the assembly of the connector 1 and the mating connector A are further suppressed.

[0047] Similarly, in the present embodiment, although not particularly illustrated, when the mating connector A attempts to be assembled to the connector 1 by coming off from the normal assembly direction D11 to the right direction D22, in the second direction D2, the side surfaces of the assembly guide portion 23 and the mating assembly guide portion A2 come into contact with each other, and / or the side surfaces of the terminal T1 of the connector 1 and the mating terminal T2 of the mating connector A come into contact with each other. At this time, as shown in FIG. 4C, by the engagement in the third direction D3 between the engaged portion 212 and the engaging portion 312, while preventing the detachment of the connector body 2 from the guide member 3, the guided portion 211 (see FIG. 5B) is guided by the guide portion 311 in the second direction D2, so that the connector body 2 relatively moves in the right direction D22 from a predetermined position with respect to the guide member 3. During this relative movement in the right direction D22, as shown in FIG. 5B, the spring (biasing member) 4 is sandwiched between the opposing wall 22a on the left direction D21 side of the main body side housing portion 22 and the opposing wall 32b on the right direction D22 side of the guide member side housing portion 32, and thus elastically deforms so as to contract in the second direction D2. As a result, a restoring force (elastic force) of the spring (biasing member) 4 that biases the connector body 2 in the left direction D21 with respect to the guide member 3 is generated. Therefore, at least when the mating connector A is removed from the connector 1, the connector body 2 returns to a predetermined position with respect to the guide member 3 (see FIGS. 4A and 5A).

[0048] Note that, in the present embodiment, the wiring portion W1 electrically connected to the connector 1 is constituted by a flexible electric wire instead of a connection pad (printed circuit) of a substrate. In this case, as described above, the internal stress and internal strain on the connector 1 side generated when the connector body 2 moves from a predetermined position with respect to the guide member 3 are absorbed by the bending of the electric wire (wiring portion) W1, so that the internal stress and internal strain in the connector structure C are further suppressed.

[0049] According to the connector 1 according to the present embodiment configured as described above, it includes a connector body 2 that is assembled with a mating connector A, and a guide member 3 that holds the connector body 2 so as to be movable in at least one of a first direction D1, a second direction D2, and a third direction D3. Therefore, when attempting to assemble the mating connector A by deviating from the normal assembly direction D11 (the first direction D1), the connector body 2 moves in a second direction D2 and / or a third direction D3 that intersects the first direction D1 with respect to the guide member 3, or moves in the first direction D1. As a result, the force that attempts to forcibly assemble the connector 1 and the mating connector A by deviating from the normal assembly direction D11 (the first direction D1) can be released in at least one of the first direction D1, the second direction D2, and the third direction D3, so that the generation of internal stress and internal strain within the connector structure C is suppressed.

[0050] Also, according to the connector 1 according to the present embodiment, the guide member 3 is provided at a position where the wiring portion W1 can be led out from the connection portion T12 with the terminal T1 to the back surface 2b side of the connector body 2. Therefore, by leading out the wiring portion W1 from the back surface 2b side of the connector body 2, while reducing the width of the connector structure C, good electrical characteristics are easily obtained in the transmission path within the connector structure C.

[0051] In the present embodiment, the guide member 3 includes a detachment prevention portion 31 that prevents the connector body 2 from detaching from the guide member 3. The detachment prevention portion 31 has a guide portion 311, and the connector body 2 has a guided portion 211 that is guided by the guide portion 311. In this case, while preventing the connector body 2 from detaching from the guide member 3, the connector body 2 can be moved in a desired moving direction with respect to the guide member 3.

[0052] In this embodiment, the connector 1 includes a biasing member 4 disposed so as to straddle the main body side accommodating portion 22 and the guide member side accommodating portion 32. When the connector main body 2 moves from a predetermined position with respect to the guide member 3, the biasing member 4 biases the connector main body 2 in the direction opposite to the direction in which the connector main body 2 has moved so that the connector main body 2 returns to the predetermined position. In this case, when repeatedly assembling and disassembling with the mating connector A, the connector 1 does not stay at a position deviated from the predetermined position. Therefore, it is suppressed that the connector 1 and the mating connector A become difficult to assemble due to the connector 1 being located at a position deviated from the predetermined position.

[0053] In this embodiment, the main body side accommodating portion 22 and the guide member side accommodating portion 32 each have opposing walls 22a, 22b, 32a, 32b that face the end portions 4a, 4b of the spring (biasing member) 4, and at least one of the main body side accommodating portion 22 and the guide member side accommodating portion 32 has a retaining portion G that protrudes from the opposing walls 22a, 22b, 32a, 32b and engages with the spring (biasing member) 4. In this case, when assembling the connector 1, the spring (biasing member) 4 is prevented from detaching from the connector main body 2 and / or the guide member 3, so that the assembly of the connector 1 becomes easier.
