AI Technical Summary
In existing connector designs, the bending of electrical wires to avoid interference with other components requires a large clearance, which can be impractical due to increased bending radius based on wire material or thickness.
The connector design features a plurality of terminals formed from a metal plate, extending in parallel, and a resin housing covering these terminals. The terminals have first and second extension portions, where the second extension portions intersect the mounting direction, allowing the electrical wires to extend differently without bending.
This design effectively prevents electrical wires from interfering with other components by allowing them to extend in a direction different from the mounting direction without bending, thus reducing the need for large clearances.

[0004] [Patent Document 1] JP 2012-256573 A Summary of the Invention [Problem to be solved by the invention]
[0005] Incidentally, there may be other components other than the connector on the opposite side of the housing with respect to the connector in the mounting direction. In this case, it is possible to bend each cable (hereinafter referred to as electric wire) to avoid interference with the other components. However, depending on the material or thickness of the electric wire, the bending radius of the electric wire may become large. For this reason, even if each electric wire is bent, it is necessary to set a large clearance between the connector body and the other components so that the electric wire does not interfere with the other components.
[0006] An object of the present disclosure is to provide a connector that can suppress interference between electric wires and other components. [Means for solving the problem]
[0007] The connector disclosed herein is a connector that is attached to an equipment case and comprises a plurality of terminals formed from a metal plate and extending in parallel to each other, and a resin housing covering the plurality of terminals, wherein each of the terminals has a first extension portion extending in the attachment direction of the connector to the case, and a second extension portion extending from a portion of the first extension portion opposite the case and to which an electric wire is connected, wherein the plate thickness directions of the plurality of first extension portions are consistent with each other, and the plurality of second extension portions extend in a direction that intersects the attachment direction and in a planar direction perpendicular to the plate thickness direction. Effect of the Invention
[0008] According to the present disclosure, interference of the electric wire with other components can be suppressed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. [1] The connector disclosed herein comprises a plurality of terminals formed from a metal plate and extending in parallel with each other, and a resin housing covering the plurality of terminals, and is mounted to a case of an equipment, wherein each of the terminals has a first extension portion extending in an attachment direction of the connector to the case, and a second extension portion extending from a portion of the first extension portion opposite the case and to which an electric wire is connected, the plate thickness directions of the plurality of first extension portions being coincident with each other, and the plurality of second extension portions extending in a direction intersecting the attachment direction and in a planar direction perpendicular to the plate thickness direction.
[0011] According to this configuration, the second extension portion of each terminal extends in a planar direction that intersects with the mounting direction and is perpendicular to the plate thickness direction of the first extension portion. Therefore, the direction in which the electric wire connected to the second extension portion extends can be made different from the mounting direction without bending the electric wire. Therefore, it is possible to prevent the electric wire from interfering with other components.
[0012] [2] It is preferable that the multiple terminals are embedded in the housing while being spaced apart from one another. According to this configuration, the insulating resin housing is interposed between the terminals, so that the terminals can be electrically insulated from each other.
[0013] [3] It is preferable that the first extension portions are arranged in parallel to one another in the planar direction, and the second extension portions are arranged in parallel to one another in the planar direction. According to this configuration, the first extension portions and the second extension portions are located on the same plane, which makes it possible to suppress an increase in the size of the housing in the direction perpendicular to the surface direction, i.e., in the plate thickness direction of the first extension portions, and therefore an increase in the size of the connector.
[0014] [4] It is preferable that, among the multiple second extension portions, the second extension portion that is farthest from the case in the mounting direction has an inclined portion that is connected to the first extension portion and extends at an angle with respect to the mounting direction, and that the housing has an outer surface that extends along the inclined portion and covers the inclined portion.
[0015] According to this configuration, the terminals can be made more compact than when the second extending portion, which is the furthest from the case, does not have the inclined portion. Also, since the housing has an outer surface that extends along the inclined portion and covers the inclined portion, the housing can also be made compact. Therefore, the increase in the size of the connector can be suppressed.
[0016] [5] It is preferable that each of the second extension portions has a wire connection portion to which each of the electric wires is connected and a straight portion continuing to the wire connection portion, and that the multiple wire connection portions are parallel to each other in a direction perpendicular to the extension direction of the straight portion.
[0017] According to this configuration, since the plurality of electric wire connection parts are arranged in parallel to each other in a direction perpendicular to the extending direction of the straight portion, the lengths of the electric wires connected to the electric wire connection parts can be easily made the same, thereby suppressing an increase in the types of electric wires used in the connector.
[0018] [6] It is preferable that the terminals each include a plurality of electric wires connected thereto, each of the second extension portions has an electric wire connection portion to which each of the electric wires is connected and a straight portion continuing to the electric wire connection portion, each of the electric wire connection portions is covered by the housing, and each of the electric wires extends in the extension direction of the straight portion.
[0019] According to this configuration, each electric wire connection portion is covered by the housing. Therefore, each electric wire connection portion can be protected by the housing. Also, each electric wire extends from the housing in the extending direction of the straight portion. Therefore, load is less likely to be applied to the electric wire connection portion. Therefore, the durability of the connector can be increased.
[0020] [7] It is preferable to have a metallic shield shell that covers the outer periphery of the portion of the housing that covers the multiple terminals. According to this configuration, each terminal covered by the housing can be electromagnetically shielded.
[0021] [8] It is preferable that each of the terminals has a third extension portion extending in the plate thickness direction from the case side portion of the first extension portion, each of the third extension portions has a bolt hole penetrating the third extension portion in the mounting direction, the housing has a tubular portion penetrating the housing in the mounting direction and accommodating each of the third extension portions, and the tubular portion has an opening through which each of the bolt holes is exposed.
[0022] According to this configuration, the bolt can be easily inserted through the opening into the bolt hole of the third extension portion housed in the cylindrical portion. This allows the third extension portion of the terminal and the connection member provided inside the case to be easily fastened together with the bolt. This makes it easy to connect the connector to the device.
[0023] [Details of the embodiment of the present disclosure] Specific examples of the connector of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. Furthermore, the dimensional ratio of each part may differ in each drawing. Note that the present disclosure is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this specification, "orthogonal" does not only mean strictly orthogonal, but also includes roughly orthogonal within the scope of the effect of this embodiment.
[0024] As shown in FIG. 1, a connector 10 is attached to a case 101 of a device 100 for a vehicle, such as a motor or an inverter. An opening 102 into which a portion of the connector 10 is inserted and two fixing holes 103 for fixing the connector 10 are provided on the outer surface of the case 101. Three metal connection members 104 protruding from the opening 102 are provided in parallel inside the case 101. Each connection member 104 protrudes outward beyond the outer surface of the case 101. Each connection member 104 is provided with a screw hole 105.
[0025] (Connector 10 Configuration) 1 and 2, the connector 10 includes a plurality of terminals 20, a plurality of electric wires 30, a resin housing 40, and a metal shield shell 80. The connector 10 includes, for example, three terminals 20A, 20B, and 20C and three electric wires 30.
[0026] Each terminal 20, each electric wire 30, and the housing 40 are integrated by insert molding. Each terminal 20 and each electric wire 30 are embedded in the housing 40 while being electrically connected to each other. The multiple terminals 20 are embedded in the housing 40 while being spaced apart from each other. The multiple electric wires 30 extend in the same direction from the housing 40. The shield shell 80 covers a part of the outer periphery of the housing 40, thereby electromagnetically shielding each terminal 20 and each electric wire 30.
[0027] Hereinafter, the attachment direction of the connector 10 to the case 101 will be referred to as a first direction Z, the extension direction of each electric wire 30 will be referred to as a second direction X, and the direction perpendicular to both the first direction Z and the second direction X will be referred to as a third direction Y. In this embodiment, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.
[0028] (Configuration of electric wire 30) 3, the electric wire 30 has a core wire 31 and an insulating coating 32 that covers the outer periphery of the core wire 31. The electric wire 30 has an exposed portion 31a where the core wire 31 is exposed from the insulating coating 32 at an end portion of the electric wire 30. The exposed portion 31a is electrically connected to the terminal 20.
[0029] The exposed portion 31a is subjected to a waterproofing treatment to prevent the core wire 31 from coming into contact with water. In this embodiment, the waterproofing treatment is the application of an adhesive to the exposed portion 31a. By applying the adhesive, contact between the core wire 31 and water is prevented even if water penetrates inside the housing 40. In addition, when the core wire 31 is a stranded wire formed by twisting together a plurality of metal strands, water is prevented from penetrating between the metal strands due to capillary action. In this embodiment, the exposed portion 31a functions as a coating portion where an adhesive is applied to the core wire 31 exposed from the insulating coating 32. It is not essential to provide a coating portion on the electric wire 30.
[0030] The core wire 31 may be made of, for example, a metal material such as a copper-based or aluminum-based material. The insulating coating 32 may be made of, for example, a resin material mainly composed of a polyolefin-based resin such as cross-linked polyethylene or cross-linked polypropylene.
[0031] As shown in FIG. 2, the multiple electric wires 30 are arranged in parallel in the first direction Z at intervals. (Terminal 20 Configuration) The terminal 20 is formed of a metal plate, and may be made of, for example, an iron-based, copper-based, or aluminum-based metal material.
[0032] The terminal 20A, the terminal 20B, and the terminal 20C are provided at positions farther from the case 101 in the first direction Z in this order. Terminals 20B and 20C have the same or corresponding configuration as terminal 20A. Hereinafter, the configuration of terminal 20A, which is the furthest from case 101 in the first direction Z, will be described in detail. In the configurations of terminals 20B and 20C, the same components as those of terminal 20A are given the same reference numerals, and components corresponding to terminal 20A are given reference numerals in which the suffix "A" of the reference numeral "2*A" indicating the configuration of terminal 20A has been changed to "B" and "C," respectively, thereby omitting redundant explanations.
[0033] As shown in FIG. 4, the terminal 20A has a first extending portion 21A, a second extending portion 22A, and a third extending portion . (Configuration of first extension portions 21A, 21B, 21C) The first extending portion 21A extends in a first direction Z. The plate thickness direction of the first extending portion 21A coincides with the third direction Y.
[0034] The plate thickness directions of the multiple first extension portions 21A, 21B, 21C are aligned with each other in the second direction X. The first extension portions 21A, 21B, 21C are formed in this order so as to be longer.
[0035] (Configuration of second extension parts 22A, 22B, 22C) The second extending portion 22A extends from a portion of the first extending portion 21A opposite to the case 101. The electric wire 30 is connected to the second extending portion 22A. The plate thickness direction of the second extending portion 22A coincides with the third direction Y.
[0036] The second extension portions 22A, 22B, 22C extend in a surface direction that intersects with the first direction Z and is perpendicular to the thickness direction of the first extension portion 21A. The second extension portions 22A, 22B, 22C are formed longer in this order. Hereinafter, the surface direction perpendicular to the thickness direction of the first extension portion 21A may be simply referred to as the "surface direction."
[0037] The second extending portion 22A has an electric wire connecting portion 23 to which the exposed portion 31a of the electric wire 30 is connected, and a straight portion 24A continuing to the electric wire connecting portion 23. The exposed portion 31a is crimped to the electric wire connecting portion 23. The straight portion 24A extends linearly in the second direction X. Therefore, the straight portion 24A extends perpendicular to the first extending portion 21A. Each electric wire 30 extends in the extension direction of each straight portion 24A, 24B, 24C, i.e., the second direction X.
[0038] The multiple electric wire connection portions 23 are arranged in parallel to one another in a direction perpendicular to the extending direction of the straight portion 24A, that is, in the first direction Z. Similarly, the multiple straight portions 24A, 24B, 24C are arranged in parallel to one another in the first direction Z.
[0039] The second extending portion 22A has an inclined portion 25A that connects an end of the first extending portion 21A and an end of the straight portion 24A. The inclined portion 25A is continuous with the first extending portion 21A and extends in the planar direction at an incline with respect to the first direction Z. The inclined portion 25A is inclined so as to approach the straight portion 24A in the second direction X as it becomes farther away from the first extending portion 21A in the first direction Z. The inclined portion 25A is formed to be longer than the inclined portion 25B.
[0040] Terminal 20C does not have a structure corresponding to inclined portions 25A and 25B. That is, second extension portion 22C of terminal 20C is composed of electric wire connection portion 23 and straight portion 24C. Therefore, in terminal 20C, first extension portion 21C and straight portion 24C are directly connected to each other.
[0041] As a result, the first extension portions 21A, 21B, and 21C are arranged in parallel to one another in the planar direction. The second extension portions 22A, 22B, and 22C are arranged in parallel to one another in the planar direction. That is, the first extension portions 21A, 21B, and 21C and the second extension portions 22A, 22B, and 22C are located on the same plane.
[0042] (Configuration of third extension portion 26) The third extension portion 26 extends in the third direction Y from a portion of the first extension portion 21A on the case 101 side. In other words, the third extension portion 26 extends perpendicular to the first extension portion 21A in the plate thickness direction from a portion of the first extension portion 21A opposite to the second extension portion 22A. The plate thickness direction of the third extension portion 26 coincides with the first direction Z.
[0043] The plate thickness directions of the multiple third extension portions 26 coincide with each other. The multiple third extension portions 26 are arranged in parallel to each other in the second direction X. The third extension portion 26 has a bolt hole 27 penetrating the third extension portion 26 in the first direction Z. As shown in Fig. 5, a bolt 110 is inserted into the bolt hole 27 and fastened to a screw hole 105 of the connection member 104, whereby the terminal 20 is electrically connected to the connection member 104.
[0044] (Configuration of housing 40) 2, the housing 40 has a main body 50 that collectively covers the multiple terminals 20, and multiple protrusions 60 that protrude from the main body 50 in the second direction X and individually cover the multiple electric wires 30. The housing 40 has, for example, three protrusions 60. The three protrusions 60 are provided at intervals from one another in the arrangement direction of the multiple electric wires 30, i.e., in the first direction Z.
[0045] The housing 40 is made of an insulating resin material, such as polybutylene terephthalate (PBT).
[0046] (Configuration of main body 50) As shown in FIGS. 2 and 3, the main body 50 has a cylindrical portion 51 penetrating in the first direction Z, and a holding portion 53 extending in the first direction Z from the outer periphery of the cylindrical portion 51.
[0047] The cylindrical portion 51 houses each of the third extension portions 26. The cylindrical portion 51 has openings 51a through which each of the bolt holes 27 is exposed. The openings 51a penetrate the cylindrical portion 51 in the first direction Z. The openings 51a have an elliptical shape that is long in the second direction X.
[0048] 5, an insertion portion 52 to be inserted into an opening 102 of a case 101 is provided at one end of the cylindrical portion 51 in the first direction Z. An annular seal member 70 is provided on an outer circumferential surface of the insertion portion 52. The seal member 70 provides a seal between the insertion portion 52 and the case 101.
[0049] Although not shown, a service cover that closes the opening 51a is attached to the other end opposite to the one end of the cylindrical portion 51 in the first direction Z. 2 and 5, the holding portion 53 extends from the outer periphery of the other end of the cylindrical portion 51 to the opposite side to the case 101 in the first direction Z. The holding portion 53 collectively covers the multiple first extending portions 21A, 21B, 21C and the multiple second extending portions 22A, 22B, 22C.
[0050] The holding portion 53 has an outer surface 53a that extends along the inclined portion 25A of the terminal 20A and covers the inclined portion 25A. The outer surface 53a extends in a plane direction perpendicular to the direction in which the inclined portion 25A extends.
[0051] (Configuration of protrusion 60) 2, each protrusion 60 has a first portion 61 in which the insulating coating 32 and the exposed portion 31a of the electric wire 30 are embedded, and a second portion 62 in which the electric wire connection portion 23 is embedded. The electric wire 30 extends in the second direction X from the first portion 61. The second portion 62 protrudes from an end portion of the holding portion 53 in the second direction X. Each first portion 61 protrudes from an end portion of the second portion 62 in the second direction X.
[0052] 6, the first portion 61 has, for example, a circular outer shape in a cross section perpendicular to the second direction X. The second portion 62 has, for example, a rectangular outer shape in a cross section perpendicular to the second direction X. The thickness of the second portion 62 in the first direction Z is greater than the thickness of the first portion 61 in the first direction Z. The thickness of the second portion 62 in the third direction Y is slightly greater than the thickness of the first portion 61 in the first direction Z.
[0053] (Configuration of the first connecting portion 63 and the second connecting portion 64) 2, the housing 40 has a plurality of first connecting portions 63 connecting two first portions 61 adjacent to each other in the first direction Z, and a plurality of second connecting portions 64 connecting two second portions 62 adjacent to each other in the first direction Z. The housing 40 has, for example, two each of the first connecting portions 63 and the second connecting portions 64.
[0054] Hereinafter, the two first portions 61 adjacent to each other in the first direction Z will be simply referred to as "two first portions 61," and the two second portions 62 adjacent to each other in the first direction Z will be simply referred to as "two second portions 62."
[0055] The first connecting portion 63 is provided at a position away from the second portion 62 in the second direction X. More specifically, the first connecting portion 63 is provided at a position closer to the tip 60c than the intermediate portion 60b between the base end 60a and the tip 60c of the protruding portion 60 in the protruding direction of the protruding portion 60, i.e., in the second direction X. Therefore, the first connecting portion 63 partially connects the two first portions 61. The base end 60a is formed by the second portion 62. The intermediate portion 60b and the tip 60c are formed by the first portion 61.
[0056] The insulating coating 32 of the electric wire 30 is embedded in a portion of the protruding portion 60 closer to the tip 60c than to the intermediate portion 60b. Therefore, the first connecting portion 63 connects the portions of the two first portions 61 where the insulating coating 32 is embedded.
[0057] 6, the first connecting portion 63 is located inward of outer surfaces 61a on both sides of each first portion 61 in the third direction Y. Therefore, the thickness of the first connecting portion 63 in the third direction Y is smaller than the thickness of the first portion 61 in the third direction Y.
[0058] 2, the second connecting portion 64 is provided at a position away from the holding portion 53 in the second direction X. Therefore, the second connecting portion 64 partially connects the two second portions 62. The second connecting portion 64 is provided between the holding portion 53 and the first connecting portion 63 in the second direction X. The second connecting portion 64 connects the portions of the two second portions 62 where the electric wire connection portions 23 are embedded.
[0059] 7, the second connecting portion 64 is located inward of the outer surfaces 62a on both sides of each second portion 62 in the third direction Y. Therefore, the thickness of the second connecting portion 64 in the third direction Y is smaller than the thickness of the second portion 62 in the third direction Y.
[0060] (Shield Shell 80 Configuration) 1 and 8, the shield shell 80 covers the housing 40 from one side in the third direction Y. The shield shell 80 has a first shield portion 81 that covers the cylindrical portion 51 except for the insertion portion 52, and a second shield portion 83 that covers the holding portion 53 and each of the second portions 62. The first shield portion 81 and the second shield portion 83 are integrally formed.
[0061] The shield shell 80 may be made of, for example, an iron-based or aluminum-based metal material. 1, fixing portions 82 that are fixed to the case 101 are provided to protrude from both sides of the first shield portion 81 in the second direction X. The fixing portions 82 are provided with through holes 82a that penetrate in the first direction Z. Bolts 120 inserted into the through holes 82a are fastened to fixing holes 103 of the case 101, thereby fixing the shield shell 80 to the case 101.
[0062] The second shield part 83 has an outer surface 83a extending along the outer surface 53a of the housing 40. One end of the second shield part 83 in the second direction X is provided with two mounting parts 84 on which female threads are formed.
[0063] Although not shown in the drawings, a metallic cylindrical bracket that collectively covers the multiple first portions 61 is attached to the mounting portion 84. A braided member formed by braiding metal wires is attached to the bracket.
[0064] The operation of this embodiment will be described. The second extending portions 22A, 22B, 22C of each terminal 20 extend in a planar direction that intersects with the first direction Z and is perpendicular to the plate thickness direction of the first extending portions 21A, 21B, 21C. Therefore, the extending direction of the electric wires 30 connected to the second extending portions 22A, 22B, 22C can be made different from the first direction Z, which is the mounting direction of the connector 10, without bending the electric wires 30.
[0065] The effects of this embodiment will be described. (1) The connector 10 is made of a metal plate, includes a plurality of terminals 20 extending in parallel with each other, and a resin housing 40 covering the plurality of terminals 20, and is attached to a case 101 of a device 100. The terminals 20A, 20B, 20C each have a first extension portion 21A, 21B, 21C extending in a first direction Z, and a second extension portion 22A, 22B, 22C extending from a portion of the first extension portion 21A, 21B, 21C opposite to the case 101 and connected to an electric wire 30. The plate thickness directions of the plurality of first extension portions 21A, 21B, 21C are aligned with each other. The plurality of second extension portions 22A, 22B, 22C extend in a plane direction perpendicular to the first direction Z and perpendicular to the plate thickness direction.
[0066] This configuration provides the above-mentioned effects. Therefore, even if there is another component other than the connector 10 on the opposite side of the connector 10 from the case 101, it is possible to prevent the wires 30 from interfering with the other component.
[0067] (2) The multiple terminals 20 are embedded in the housing 40 while being spaced apart from one another. According to this configuration, since the insulating resin housing 40 is interposed between the terminals 20, the terminals 20 can be electrically insulated from each other.
[0068] (3) The multiple first extension portions 21A, 21B, 21C are arranged in parallel to one another in the planar direction, and the multiple second extension portions 22A, 22B, 22C are arranged in parallel to one another in the planar direction. With this configuration, the first extension portions 21A, 21B, and 21C and the second extension portions 22A, 22B, and 22C are located on the same plane, which prevents an increase in the size of the housing 40 in the direction perpendicular to the plane direction, i.e., in the thickness direction of the first extension portions 21A, 21B, and 21C, and thus prevents an increase in the size of the connector 10.
[0069] (4) Of the multiple second extension portions 22A, 22B, 22C, the second extension portion 22A that is farthest from the case 101 in the first direction Z has an inclined portion 25A that is continuous with the first extension portion 21A and extends at an angle with respect to the first direction Z. The housing 40 has an outer surface 53a that extends along the inclined portion 25A and covers the inclined portion 25A.
[0070] With this configuration, the terminals 20 can be made more compact than when the second extending portion 22A does not have the inclined portion 25A. Also, since the housing 40 has the outer surface 53a that extends along the inclined portion 25A and covers the inclined portion 25A, the housing 40 can also be made compact. Therefore, an increase in the size of the connector 10 can be suppressed.
[0071] (5) The second extending portions 22A, 22B, and 22C each have an electric wire connection portion 23 to which the electric wire 30 is connected, and straight portions 24A, 24B, and 24C continuing to the electric wire connection portion 23. The multiple electric wire connection portions 23 are arranged in parallel to one another in a direction perpendicular to the extension direction of the straight portions 24A, 24B, and 24C.
[0072] According to this configuration, since the multiple electric wire connection portions 23 are arranged in parallel in a direction perpendicular to the extending direction of the straight portions 24A, 24B, 24C, the lengths of the electric wires 30 connected to the electric wire connection portions 23 can be easily made uniform. Therefore, an increase in the types of electric wires 30 used in the connector 10 can be suppressed.
[0073] (6) The connector 10 includes a plurality of electric wires 30 connected to each of the terminals 20. Each electric wire connection portion 23 is embedded in the housing 40. Each electric wire 30 extends in the extension direction of the straight portions 24A, 24B, and 24C.
[0074] According to this configuration, each electric wire connection portion 23 is embedded in the housing 40. Therefore, each electric wire connection portion 23 can be protected by the housing 40. Also, each electric wire 30 extends from the housing 40 in the extending direction of the straight portions 24A, 24B, 24C. Therefore, load is less likely to be applied to each electric wire connection portion 23. Therefore, the durability of the connector 10 can be improved.
[0075] (7) The connector 10 includes a metallic shield shell 80 that covers the outer periphery of the portion of the housing 40 that covers the multiple terminals 20 . With this configuration, each terminal 20 embedded in the housing 40 can be electromagnetically shielded.
[0076] (8) Terminals 20A, 20B, 20C have third extension portions 26 extending in the plate thickness direction from portions of first extension portions 21A, 21B, 21C on the case 101 side. Third extension portions 26 have bolt holes 27 penetrating third extension portions 26 in first direction Z. Housing 40 has a cylindrical portion 51 penetrating housing 40 in first direction Z and accommodating each third extension portion 26. Cylindrical portion 51 has openings 51a through which each bolt hole 27 is exposed.
[0077] According to this configuration, the bolt 110 can be easily inserted through the opening 51a into the bolt hole 27 of the third extension portion 26 housed in the cylindrical portion 51. This allows the third extension portion 26 and the connection member 104 provided inside the case 101 to be easily fastened together by the bolt 110. This makes it easy to connect the connector 10 and the device 100.
[0078] (9) Each electric wire 30 has a core wire 31 and an insulating coating 32 covering the outer periphery of the core wire 31, and an exposed portion 31a of the core wire 31 exposed from an end of the insulating coating 32 is connected to each terminal 20. The insulating coating 32 and the exposed portion 31a of each electric wire 30 are embedded in the first portion 61 of each protrusion 60. The first connecting portion 63 connects the portions of two adjacent first portions 61 where the insulating coating 32 is embedded.
[0079] A connector including a housing 40 in which an electric wire 30 is embedded is provided with an adhesive coating portion on the core wire 31 exposed from the insulating coating 32 in order to waterproof the space between the electric wire 30 and the housing 40. When two adjacent protrusions 60 have their embedded coating portions connected to each other by a connecting portion, there is a risk that the adhesive will peel off from the core wire due to thermal contraction of each protrusion 60 as it approaches the connecting portion during injection molding of the housing 40.
[0080] In this regard, according to the above configuration, the first connecting portion 63 connects the portions of the two first portions 61 where the insulating coating 32 is embedded, and therefore the above-mentioned inconvenience is unlikely to occur.
[0081] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.
[0082] Each third extension portion 26 may extend in the first direction Z in the planar direction. In this case, the axis of each bolt hole 27 is perpendicular to the planar direction. In such a connector, for example, each third extension portion 26 and each connection member 104 are fastened to each other in the third direction Y by a bolt.
[0083] The connection between the third extension portion 26 and the connection member 104 is not limited to bolt fastening. For example, the third extension portion 26 and the connection member 104 may be overlapped and sandwiched by a spring member or the like.
[0084] Instead of the shield shell 80, the housing 40 can be covered with a braided member formed by weaving metal wires. For example, when the voltage applied to the connector 10 is low, the shield shell 80 can be omitted from the connector 10.
[0085] Each electric wire connection portion 23 may be exposed from the housing 40. In this case, each electric wire connection portion 23 may be subjected to various insulating treatments and waterproofing treatments. The electric wire connection portions 23 may be arranged in parallel in a direction intersecting the first direction Z in the planar direction.
[0086] The outer surface 53a of the housing 40 does not have to extend along the inclined portion 25A. The second extension parts 22A, 22B, and 22C do not have to be arranged in parallel in the planar direction. The second extension parts 22A, 22B, and 22C may be arranged in parallel in a direction intersecting the planar direction, for example. Such a configuration can be realized, for example, by making the lengths of the third extension parts 26 different.
[0087] In the connector 10 of the present embodiment, the terminals 20 and the wires 30 are embedded in the housing 40. However, the connector 10 may be configured such that the terminals 20 and the wires 30 are covered by a housing having a plurality of divided bodies that are assembled to one another.
[0088] The straight line portions 24A, 24B, 24C may extend at an angle relative to the first extending portions 21A, 21B, 21C in the planar direction, and the angles formed between the straight line portions 24A, 24B, 24C and the first extending portions 21A, 21B, 21C may be set to any angle, such as 100°. In this case, each protrusion 60 may be inclined at the above-mentioned any angle relative to the first direction Z.
[0089] The number of terminals 20 and wires 30 can be changed as appropriate depending on the specifications of the connector 10. [Explanation of symbols]
