[0003] Patent document 1: Japanese unexamined patent application, first publication no. 2022-151014 PRESENTATION OF THE INVENTION

[0004] With this type of connector, the direction of the conductive element extending from the terminal within the housing (the conductive element's direction of extension) can vary depending on the application. Because of this, multiple housing types with different conductive element extension directions relative to the terminal receiving section are manufactured to suit the various connector applications. Since multiple housing types, each corresponding to a multiple housing type, are currently produced, the manufacturing costs of the connector, including the housing and housing, are high.

[0005] One embodiment provides a casing and a connector that reduce the manufacturing costs of the connector.

[0006] A casing according to one embodiment is a casing for attachment to a housing. The housing has a terminal receiving section that receives a terminal, a receiving section for a conductive element that is arranged adjacent to the terminal receiving section so that it is immovable and receives a portion of a conductive element extending from the terminal, and an opening that opens the terminal receiving section and the receiving section for a conductive element outwards in a first cutting direction that intersects an arrangement direction of the terminal receiving section and the receiving section for a conductive element. The casing has the following: a first casing that covers at least one opening corresponding to the terminal receiving section; and a second casing that covers at least one second opening corresponding to the receiving section for a conductive element.The first shell and the second shell are rotatable relative to each other about an axis that extends in the first cutting direction.

[0007] A connector according to one embodiment comprises: a terminal; a housing having a terminal receiving section that receives the terminal, a receiving section for a conductive element that is arranged adjacent to the terminal receiving section so that it is immovable and receives part of a conductive element extending from the terminal, and an opening that opens the terminal receiving section and the receiving section for a conductive element outwards in a first cutting direction that intersects an arrangement direction of the terminal receiving section and the receiving section for a conductive element; and the aforementioned casing.

[0008] The casing and connector according to one embodiment of the present invention allow the manufacturing costs of the connector to be reduced.

[0009] The following descriptions illustrate embodiments with reference to the drawings. In the following description, assemblies with the same or similar functions are named using the same reference numerals. Redundant descriptions of these assemblies can be omitted.

[0010] In the present disclosure, the terms are defined as follows. The term "connection" is not limited to a mechanical connection and may also include an electrical connection. Furthermore, the term "connection" is not limited to a case in which two elements that are connection targets are directly connected and may include a case in which two elements that are connection targets are connected to another, intervening element.

[0011] In the present disclosure, a +X direction, a -X direction, a +Y direction, a -Y direction, a +Z direction, and a -Z direction are defined as follows. The +X direction is a direction in which a sheath 6 and a housing 5 of a connector 3 are arranged successively (see Fig. 1 to 3). The -X direction is a direction opposite to the +X direction. If the +X and -X directions are not distinguished, they are simply referred to as the "X direction". The Y direction is a direction that intersects the X direction (for example, orthogonal to it). The +Y direction is a direction from one of two terminals 4 of the connector 3 to the other (see Fig. 1 and Fig. 2) The -Y direction is a direction opposite to the +Y direction. When the +Y and -Y directions are not distinguished, they are simply referred to as the "Y direction". The +Z direction is a direction that intersects the X and Y directions (for example, orthogonally to them). The +Z direction is a direction in which a receiving section 52 for a conductive element and a terminal receiving section 51 of the housing 5 are arranged sequentially (see Fig. 3) The -Z direction is the opposite direction to the +Z direction. When the +Z and -Z directions are not distinguished, they are simply referred to as the "Z direction." The Z direction is an example of an "arrangement direction of the terminal receiving section 51 and the receiving section 52 for a conductive element." The X direction is an example of a "first cutting direction" that intersects the arrangement direction. For simplicity, the side in the +X direction can subsequently be referred to as the "front" and the side in the -X direction as the "back." <1. Connector>

[0012] As in Fig. As shown in Figures 1 to 3, connector 3 of one embodiment is a component for electrically connecting an electrical wire 2 to a connector counterpart (not shown). Connector 3 is, for example, a connector used in a vehicle such as an electric vehicle (EV), a hybrid electric vehicle (HEV), or a plug-in hybrid electric vehicle (PHEV). Connector 3 is, for example, a high-voltage connector carrying a current of 100 V or more. Connector 3 of the present embodiment is a connector corresponding to two electrodes. However, connector 3 could, for example, be a connector corresponding to one electrode or three or more electrodes.

[0013] Connector 3 has terminal 4, housing 5, and casing 6. Connector 3, together with the electrical wire 2 (conducting element) connected to terminal 4 of connector 3, forms routing unit 1. <2nd connection>

[0014] Connection 4 is located in connection section 51 of the housing 5 described below. In the Fig. In connectors 3 shown in Figures 1 to 3, two terminals 4 are arranged in the Y-direction within the terminal receiving section 51. The number of terminals 4 in connector 3 is not limited to two, but can be any number. Furthermore, the arrangement of the majority of terminals 4 within the terminal receiving section 51 can be any number. <3. Case>

[0015] As in Fig. 2 and Fig. As shown in Figure 3, the housing 5 consists of a material with electrically insulating properties (for example, a synthetic resin material). The housing 5 has the connection receiving section 51, the receiving section 52 for a conductive element, an opening 53, an insulating wall 54, and a mounting section 55. <4. Connection section>

[0016] The connection receiving section 51 is a space within the housing 5, wherein the space accommodates the connection 4 described above. The connection receiving section 51 of the present embodiment is a space within a tubular section 56 that extends in the X direction and is open at both ends. In such a configuration, the connection receiving section 51 is open on one side at the first end 561 of the tubular section 56, which is positioned at the front (side in the +X direction), and on one side at the second end 562 of the tubular section 56, which is positioned at the rear (side in the -X direction).

[0017] A section of the tubular part 56 on the side at the first end 561 is a fitting section that is fitted into the connector counterpart. The terminal 4, received in the terminal receiving section 51, is exposed to the outside of the housing 5 through an opening in the tubular part 56 on the side at the first end 561. In such a configuration, when the section of the tubular part 56 on the side at the first end 561 is fitted into the connector counterpart, the terminal 4 is connected to a terminal (not shown).

[0018] An opening of the tubular section 56 on the side at the second end 562 is a first opening 531 that opens the connection receiving section 51 from the rear (side in -X direction) to the outside. <5. Recording section for a conductive element>

[0019] As in Fig. As shown in Figure 3, the receiving section 52 for a conductive element (receiving section for an electrical wire) is a space in the housing 5, wherein the space receives a portion of the electrical wire 2 (conductive element) extending from the terminal 4 received in the terminal receiving section 51. The receiving section 52 for a conductive element is arranged adjacent to the terminal receiving section 51 so that it is immovable. A proximal end portion of the electrical wire 2, located adjacent to the terminal 4, is received in the receiving section 52 for a conductive element, and a portion of the electrical wire 2 extending further from the proximal end portion is brought out to the outside of the receiving section 52 for a conductive element.In the following description, a direction in which the electrical wire 2 extends in the receiving section 52 for a conductive element can be referred to as the "extension direction of the receiving section 52 for a conductive element".

[0020] The receiving section 52 for a conductive element in the present embodiment is a space within a guide section 57 that guides the electrical wire 2, extending from the terminal 4, in a predetermined direction. The guide section 57 is formed integrally with the tubular section 56. That is, the tubular section 56 and the guide section 57 are fixed so that they do not move relative to each other. The guide section 57 is connected to a section of the tubular section 56 on the side at the second end 562. In such a configuration, the receiving section 52 for a conductive element is in contact with the terminal receiving section 51 on the side at the second end 562 of the tubular section 56.

[0021] In the present embodiment, the guide section 57 extends from the tubular section 56 in a direction intersecting the X-direction (for example, a direction orthogonal to the X-direction). The guide section 57 guides the electrical wire 2 in the direction in which it extends from the tubular section 56. The direction of extension of the guide section 57 corresponds to the direction of extension of the receiving section 52 for a conductive element. In the Fig. In the housing 5 shown in Figure 3, the guide section 57 extends in the -Z direction with respect to the tubular section 56. In the housing 5, for example, the guide section 57 can extend obliquely to the side in the -Y direction or to the side in the +Y direction, while, viewed from the X direction, it runs towards the -Z direction with respect to the tubular section 56.

[0022] The guide section 57 has a second opening 532, which opens the receiving section 52 for a conductive element to the outside of the housing 5 from the rear (side in -X direction).

[0023] The opening 53 of the housing 5 opens the connection receiving section 51 and the receiving section 52 described above for a conductive element to the outside in the -X direction (first cutting direction). The opening 53 has the first opening 531 and second opening 532 described above. <6. Insulating wall>

[0024] As in Fig. 2 and Fig. As shown in Figure 3, the insulating wall 54 is positioned between the adjacent terminals 4 in the terminal receiving section 51 to electrically isolate the adjacent terminals 4 from each other. Specifically, the insulating wall 54 is positioned between the terminals 4 arranged adjacent in the Y-direction within the terminal receiving section 51. The insulating wall 54 is formed in a shape that extends in the X-direction and Z-direction, with the Y-direction representing the thickness direction. <7. Fastening section>

[0025] The fastening section 55 is a section of the housing 5 for fastening the sleeve 6 to the housing 5. In the present embodiment, the fastening section 55 has a fastening hole 551 through which a shaft section of a fastening bolt 7 passes for fastening the sleeve 6. The fastening section 55 is positioned on the side at the second end 562 of the tubular section 56 and projects from the tubular section 56 in a direction intersecting the X-direction (+Z-direction in the illustrated example). The fastening hole 551 passes through the fastening section 55 in the X-direction. In the present embodiment, the fastening section 55 is formed integrally with the tubular section 56, which forms the connection receiving section 51, and is positioned away from the guide section 57, which forms the receiving section 52 for a conductive element. <8th cover>

[0026] As in Fig. As shown in Figure 1, the cover 6 is attached to the housing 5 in such a way that the opening 53 (see Fig. 3) of the housing 5 is covered. As in Fig. 1 and Fig. As shown in Figure 3, the casing 6 has a first casing 10, a second casing 20, a fixing section 30, and a fixed section 40. The first casing 10 and the second casing 20 are made of a material with electrically insulating properties (for example, a synthetic resin).

[0027] The first shell 10 covers at least the first opening 531 of the case 5 (see Fig. 3), which corresponds to the connection receiving section 51. The second sleeve 20 covers at least the second opening 532 of the housing 5 (see Fig. 3), which corresponds to recording section 52 for a conductive element. As in Fig. As shown in Figure 3, the first shell 10 and the second shell 20 are rotatable relative to each other about an axis C1 extending in the X-direction (first cutting direction). The fixing section 30 fixes the first shell 10 and the second shell 20 to each other in a non-rotatable manner. The fixing section 30 fixes the first shell 10 and the second shell 20 to each other at any desired rotational position.

[0028] The configuration of the shell 6 of the present embodiment is described in more detail below.

[0029] As in Fig. 4 and Fig. As shown in Figure 5, the first hull 10 and the second hull 20 are arranged sequentially in the -Z direction. A section of the first hull 10 on the side in the -Z direction and a section of the second hull 20 on the side in the +Z direction overlap each other. <9. First Cover>

[0030] As in Fig. 2, Fig. 4 and Fig. As shown in Figure 5, the first shell 10 of the present embodiment has a first cover section 11 and a first side wall 12.

[0031] The first cover section 11 is plate-shaped, with the X-direction representing the plate thickness direction. The first cover section 11 mainly covers the first opening 531 (see Fig. 3) of the tubular section 56 (connection receiving section 51). A section of the first cover section 11 on the side in the -Z direction is a first overlapping section 111, which overlaps a second cover section 21 of the second shell 20 described below in the X direction.

[0032] The first side wall 12 extends from a portion of a circumferential edge of the first cover section 11 in the +X direction (one side in the thickness direction of the first cover section 11). The first side wall 12 is positioned on a portion of the circumferential edge of the first cover section 11, except for an edge portion on the side in the -Z direction, which is adjacent to the second shell 20. In other words, an opening is formed on a portion of the first side wall 12 on the side in the -Z direction, with the first side wall 12 being positioned on the circumferential edge of the first cover section 11.

[0033] As in Fig. 2 and Fig. As shown in Figure 4, the first side wall 12 has a first inner surface 12a and an arc-shaped inner surface (arc inner surface) 12b.

[0034] The first inner surface 12a is a surface that faces and covers a portion of the outer circumference of the tubular section 56 in a state where the sleeve 6 is attached to the housing 5. In the present embodiment, the first inner surface 12a is formed on a section of the first side wall 12 on the side in the +Z direction. The first inner surface 12a is formed in a recessed shape and, viewed from the X direction, is recessed laterally in the +Z direction.

[0035] The arc-shaped inner surface 12b is a surface centered on axis C1, which is a relative center of rotation between the first shell 10 and the second shell 20. In the present embodiment, the arc-shaped inner surface 12b is formed on a section of the first side wall 12 adjacent to the first inner surface 12a on the side in the -Z direction. In particular, the arc-shaped inner surface 12b is configured such that it adjoins both ends of the first inner surface 12a on the side in the -Z direction with a recessed shape that, viewed from the X direction, extends towards the side in the +Z direction. In such a configuration, the arc-shaped inner surface 12b is positioned at both ends of the first cover section 11 in the Y direction. The two arc-shaped inner surfaces 12b face each other in the Y direction. <10. Second Cover>

[0036] As in Fig. 2, Fig. 4 and Fig. As shown in Figure 5, the second shell 20 of the present embodiment includes the second cover section 21 and a second side wall 22.

[0037] The second cover section 21 is plate-shaped, with the X-direction representing the plate thickness direction. The second cover section 21 mainly covers the second opening 532 (see Fig. 3) of the guide section 57 (receiving section 52 for a conductive element). A section of the second cover section 21 on the side in the +Z direction is a second overlapping section 211, which overlaps the first cover section 11 of the first shell 10 in the X direction. In the present embodiment, the second overlapping section 211 overlaps the first overlapping section 111 of the first cover section 11 on the side in the +X direction (side of the housing 5).

[0038] The second side wall 22 extends from a portion of a circumferential edge of the second cover section 21 in the +X direction (one side in the thickness direction of the second cover section 21). The second side wall 22 is positioned only at one edge section on both sides of the circumferential edge of the second cover section 21 in the Y direction, and is not positioned at edge sections on both sides of the circumferential edge of the second cover section 21 in the Z direction. In other words, openings are formed at sections of the second side wall 22 on the side in the +Z direction and the side in the -Z direction, with the second side wall 22 being formed on the circumferential edge of the second cover section 21.

[0039] An interior space of the first sheath 10 and an interior space of the second sheath 20 are connected by forming the opening on the section of the first side wall 12 on the side in the -Z direction and the opening on the section of the second side wall 22 on the side in the +Z direction. Since the opening on the section of the second side wall 22 is formed on the side in the -Z direction, the electrical wire 2 can also be guided to the outside of the guide section 57 (housing 5) in a state where the sheath 6 is attached to the housing 5.

[0040] As in Fig. 2 and Fig. As shown in Figure 4, each of the two second side walls 22 has second inner surfaces 22a and arcuate outer surfaces (arc outer surfaces) 22b.

[0041] The two second inner surfaces 22a are surfaces facing the outer surfaces of the guide section 57, which are oriented towards both sides in the Y-direction in a state in which the sleeve 6 is attached to the housing 5. In the present embodiment, each of the second inner surfaces 22a is formed on an end section of each of the second side walls 22 on the side in the -Z direction.

[0042] Each of the two arcuate outer surfaces 22b is a surface centered on the axis C1. In the present embodiment, each arcuate outer surface 22b is formed on an end section of the second side wall 22 on the side in the +Z direction. The arcuate outer surface 22b of the second side wall 22 is in surface contact with the arcuate inner surface 12b of the first side wall 12 when the second shell 20 is attached to the first shell 10. When the first shell 10 and the second shell 20 are rotated relative to the axis C1, the arcuate inner surface 12b and the arcuate outer surface 22b slide in a circumferential direction D1 around the axis C1. <11. Fixing section>

[0043] As in Fig. As shown in Figures 3 to 5, the fixing section 30 has a bolt 31, a nut 32 and an insertion hole 33.

[0044] The bolt 31 is attached to the first sleeve 10 and the second sleeve 20 and is arranged on the axis C1. In the present embodiment, the bolt 31 is a male screw section that is integrally formed with the second sleeve 20. In particular, the bolt 31 projects from a surface of the second overlapping section 211 of the second cover section 21, which forms the second sleeve 20, with the surface facing the first overlapping section 111 of the first cover section 11.

[0045] The insertion hole 33 is formed in the first cover 10, and the bolt 31 (male screw section) is inserted through the insertion hole 33. Specifically, the insertion hole 33 is formed in the first overlapping section 111 of the first cover section 11 and extends through the first overlapping section 111 in the plate thickness direction of the first overlapping section 111.

[0046] The nut 32 is screwed to the bolt 31, which is attached to the first sleeve 10 and the second sleeve 20, to fix the first sleeve 10 and the second sleeve 20 to each other in a non-rotatable manner. Specifically, the nut 32 is screwed to a distal end section of the bolt 31, which is inserted through the insertion hole 33 of the second sleeve 20, to clamp the first sleeve 10 (the first cover section 11) to the second sleeve 20 (the second cover section 21). By clamping the first sleeve 10 between the nut 32 and the second sleeve 20, the first sleeve 10 and the second sleeve 20 are fixed in a relatively non-rotatable manner. <12. Fortified Section>

[0047] As in Fig. As shown in Figures 1 to 3, the attached section 40 is a section of the shell 6 for attaching the shell 6 to the housing 5. The attached section 40 is in a state in which the shell 6 is attached to the housing 5, adjacent to the attachment section 55 of the housing 5 on the side in the -X direction. In the present embodiment, the attached section 40 has a female screw 41 to which the shank section of the fastening bolt 7 is screwed. The attached section 40 is formed integrally with the first shell 10. The attached section 40 projects from an outer surface of the first side wall 12 of the first shell 10 in a direction intersecting the X direction (+Z direction in the illustrated example).

[0048] Since the shell 6 has the attached section 40 described above, the shell 6 can be fixed to the housing 5 as follows. First, the shell 6 is attached to the housing 5, and the attached section 40 of the shell 6 is positioned next to the mounting section 55 of the housing 5 on its side in the -X direction. Then, the shaft section of the mounting bolt 7 passes through the mounting hole 551 of the mounting section 55 and is subsequently screwed into the female screw of the attached section 40, thus fixing the attached section 40 of the shell 6 to the mounting section 55 of the housing 5. The shell 6 is fixed to the housing 5 by securing the attached section 40 to the mounting section 55. <13. Advantages>

[0049] According to the present embodiment, the shell 6, which covers the opening 53 of the housing 5, comprises the first shell 10, which covers at least the first opening 531 corresponding to the connection receiving section 51 in the opening 53, and the second shell 20, which covers at least the second opening 532 corresponding to the receiving section 52 for a conductive element in the opening 53. The first shell 10 and the second shell 20 are rotatable relative to each other about an axis C1 extending in the X-direction (first cutting direction). That is, the direction in which the second shell 20, corresponding to the receiving section 52 for a conductive element, extends with respect to the first shell 10, corresponding to the connection receiving section 51, can be changed.

[0050] In such a configuration, it is possible to attach the same type of casing 6 to a plurality of housing types 5 with different extension directions of the receiving section 52 for a conductive element with respect to the connecting receiving section 51. For example, the same type of casing 6 can be attached to a housing 5-1 of a first example, which is in Fig. 1 to 4 is shown, as well as on a housing 5-2 of a second example, which is in Fig. The item shown in section 6 must be attached. This point is described below.

[0051] As in Fig. As shown in Figure 4, in the housing 5-1 of the first example, the guide section 57 with the receiving section 52 for a conductive element extends in the -Z direction relative to the tubular section 56 with the connection receiving section 51. To attach the sleeve 6 to the housing 5-1 of the first example, the relative rotational position between the first sleeve 10 and the second sleeve 20 is set such that the second sleeve 20 extends in the -Z direction relative to the first sleeve 10. By setting the relative rotational position between the first sleeve 10 and the second sleeve 20 in this way, the sleeve 6 can be attached to the housing 5-1 of the first example.

[0052] On the other hand, as in Fig. As shown in Figure 6, in the housing 5-2 of the second example, the guide section 57 with the receiving section 52 for a conductive element is inclined laterally in the +Y direction, while extending in the -Z direction with respect to the tubular section 56, which has the connection receiving section 51. To attach the sleeve 6 to the housing 5-2 of the second example, the relative rotational position between the first sleeve 10 and the second sleeve 20 is set such that the second sleeve 20 extends in the "inclined direction" described above with respect to the first sleeve 10. By setting the relative rotational position between the first sleeve 10 and the second sleeve 20 in this way, the sleeve 6 can be attached to the housing 5-2 of the second example.

[0053] As described above, the versatility of the housing 6 can be improved, since the same type of housing 6 is compatible with different types of enclosures 5. Therefore, the manufacturing costs of the connector 3, including the enclosure 5 and the housing 6, can be reduced.

[0054] According to the present embodiment, the cover 6 further comprises the fixing section 30, which fixes the first cover 10 and the second cover 20 to each other in a non-rotatable manner.

[0055] In such a configuration, the cover 6 can be easily attached to the housing 5 in a state in which the first cover 10 and the second cover 20 are held in desired rotational positions by the fixing section 30.

[0056] According to the present embodiment, the fixing section 30 of the shell 6 comprises the bolt 31, which is attached to the first shell 10 and the second shell 20 and arranged on the axis C1, as well as the nut 32 screwed to the bolt 31 to fix the first shell 10 and the second shell 20 to each other in a non-rotatable manner. In such a configuration, the first shell 10 and the second shell 20 can be reliably fixed to each other in a non-rotatable manner by the fixing section 30. Since the bolt 31 is attached to the first shell 10 and the second shell 20 and arranged on the axis C1, the first shell 10 and the second shell 20 can also be rotated relative to the axis C1 by the bolt 31. In other words, the bolt 31 of the fixing section 30 can also have the function of making the first shell 10 and the second shell 20 rotatable relative to each other.

[0057] According to the present embodiment, the bolt 31 is a male screw section that is integrally formed with the second sleeve 20. The fixing section 30 has an insertion hole 33, which is formed in the first sleeve 10 and positioned on the axis C1, and through which the bolt 31 (the male screw section) is inserted.

[0058] In such a configuration, the first shell 10 and the second shell 20 can be rotated relative to the axis C1 simply by inserting the bolt 31 provided in the second shell 20 through the insertion hole 33 of the first shell 10. Furthermore, since the bolt 31 is integrally formed with the second shell 20, the number of components of the shell 6 can be reduced compared to a case where the bolt 31 is separate from the first shell 10 and the second shell 20.

[0059] According to the present embodiment, the first shell 10 has the arcuate inner surface 12b, which is centered on the axis C1, and the second shell 20 has the arcuate outer surface 22b, which is also centered on the axis C1. The arcuate inner surface 12b and the arcuate outer surface 22b come into surface contact with each other and slide in the circumferential direction D1 around the axis C1.

[0060] In such a configuration, the first shell 10 and the second shell 20 can be rotated relatively evenly and stably. Furthermore, relative rattling between the first shell 10 and the second shell 20 can be suppressed or prevented, thus ensuring the integrity and strength of the entire shell 6.

[0061] Since the arcuate inner surface 12b and the arcuate outer surface 22b are in surface contact with each other, it is also possible to suppress or prevent the formation of a gap between the first shell 10 and the second shell 20, regardless of the relative rotational position between the first shell 10 and the second shell 20. This makes it possible to suppress or prevent the connection receiving section 51 and the receiving section 52 for a conductive element of the housing 5 from coming into contact with the outside due to a gap between the first shell 10 and the second shell 20. <14. Modification Example>

[0062] In the embodiment described above, the first shell 10 has the arcuate inner surface 12b centered on the axis C1, and the second shell 20 has the arcuate outer surface 22b centered on the axis C1. However, for example, the first shell 10 can have an arcuate outer surface and the second shell 20 an arcuate inner surface. It is sufficient if the arcuate outer surface and the arcuate inner surface come into surface contact with each other and slide around the axis C1 in the circumferential direction D1. Even with such a configuration, the same effects are achieved as in the embodiment described above.

[0063] In the embodiment described above, the first side wall 12 of the first shell 10 has the first inner surface 12a. However, the first side wall 12 need not necessarily have the first inner surface 12a.

[0064] In the embodiment described above, the first shell 10 contains the first cover section 11 and the first side wall 12. However, the first shell 10 only needs to contain at least the first cover section 11 and does not, for example, need to have the first side wall 12.

[0065] In the embodiment described above, the second side wall 22 of the second shell 20 has the second inner surface 22a. However, the second side wall 22 need not necessarily have the second inner surface 22a.

[0066] In the embodiment described above, the second shell 20 contains the second cover section 21 and the second side wall 22. However, the second shell 20 only needs to contain at least the second cover section 21 and does not, for example, need to have the second side wall 22.

[0067] In the embodiment described above, the electrical wire 2 is directly connected to terminal 4 of the connector 3. However, the electrical wire 2 need not be directly connected to terminal 4 of the connector 3. For example, a busbar (a conductive element) can be connected to terminal 4 of the connector 3, and the electrical wire 2 can be connected to terminal 4 via the busbar. In this case, either only the busbar can be accommodated in the receiving section 52 for a conductive element of the housing 5, or the busbar and part of the electrical wire 2 connected to it can be accommodated in the receiving section 52 for a conductive element of the housing 5.

[0068] In the embodiment described above, the bolt 31 of the fixing section 30, arranged on axis C1, can be a male screw section integrally formed with the second sleeve 20. However, the bolt 31 can, for example, be a male screw section integrally formed with the first sleeve 10. In particular, the bolt 31 (the male screw section) can, for example, project from a surface of the first overlapping section 111 of the first cover section 11, which forms the first sleeve 10, with the surface facing the second overlapping section 211 of the second cover section 21. In this case, the insertion hole 33, through which the bolt 31 is inserted, can be formed in the second sleeve 20.In particular, it is sufficient if the insertion hole 33 is formed in the second overlapping section 211 of the second cover section 21, which forms the second shell 20, and passes through the second overlapping section 211 in the plate thickness direction of the second overlapping section 211. With such a configuration, the same effects are achieved as in the embodiment described above.

[0069] Furthermore, for example, as in Fig. Figure 7 shows that the bolt 31 of the fixing section 30, arranged on the axis C1, is provided separately from the first shell 10 and the second shell 20, and can be attached to the first shell 10 and the second shell 20 and arranged on the axis C1 by being inserted into holes 33 and 34, which are formed in both the first shell 10 and the second shell 20. Fig. 7. The bolt 31 is inserted through the insertion hole 33 formed in the first sleeve 10 and the insertion hole 34 formed in the second sleeve 20. In this case, it is sufficient if the first sleeve 10 and the second sleeve 20 (the first cover section 11 and the second cover section 21) are clamped between a head of the bolt 31 and the nut 32 by screwing the nut 32 to the distal end section of the shank section of the bolt 31 inserted through the insertion holes 33 and 34 of the first sleeve 10 and the second sleeve 20. In such a configuration, the nut 32 screwed to the bolt 31 can be provided separately from the first sleeve 10 and the second sleeve 20 or integrally with the first sleeve 10 or the second sleeve 20.

[0070] In Fig.In Figure 7, the nut 32 is integrally formed with the second sleeve 20. The nut 32, integrally formed with the second sleeve 20, is a female screw section formed on an inner circumference of the insertion hole 34 of the second sleeve 20. Therefore, the first sleeve 10 (the first cover section 11) is clamped between the head of the bolt 31 and the nut 32 (the female screw section). The hole 34, in which the female screw section serving as the nut 32 is formed, need not, for example, pass through the second sleeve 20, but can also be a hole with a bottom. Even with such a configuration, the same effects are achieved as in the embodiment described above.

[0071] A configuration in which the nut 32 (the female bolt section) is provided integrally with the first sleeve 10 or the second sleeve 20 has the advantage of reducing manufacturing costs compared to a configuration in which the bolt 31 is provided integrally with the first sleeve 10 or the second sleeve 20.

[0072] One embodiment and examples of modifications have been described above. However, the embodiment and the examples of modifications are not limited to the examples described above. For example, the embodiment and the examples of modifications can be implemented in combination with each other.
