[0006] Patent document 1: Japanese Patent Application Publication No. 2012-256573. Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, sometimes there are other components, different from the connector, on the side opposite to the housing, across the connector in the aforementioned assembly direction. In this case, to avoid interference with other components, it is considered to bend each cable (hereinafter referred to as wire). However, depending on the material or thickness of the wire, the bending radius of the wire increases. Therefore, even when bending each wire, it is necessary to set a large gap between the connector body and other components so that these wires do not interfere with other components.

[0009] The purpose of this disclosure is to provide a connector capable of preventing wires from interfering with other components.

[0010] Solution for solving the problem

[0011] The connector disclosed herein comprises: a plurality of terminals formed by a metal plate and extending side by side; and a resin housing covering the plurality of terminals. The connector is assembled into a device housing. Each terminal has: a first extension extending in the assembly direction of the connector relative to the housing; and a second extension extending from a portion of the first extension opposite to the housing and connected to a wire. The thickness directions of the plurality of first extensions are aligned with each other, and the plurality of second extensions extend in a plane direction intersecting the assembly direction and orthogonal to the thickness direction.

[0022] [Description of embodiments of this disclosure]

[0023] First, the implementation methods of this disclosure are listed and explained.

[0024] [1] The connector disclosed herein comprises: a plurality of terminals formed by a metal plate and extending side by side; and a resin housing covering the plurality of terminals. The connector is mounted on a device housing. Each terminal has: a first extension extending in the mounting direction of the connector relative to the housing; and a second extension extending from a portion of the first extension opposite to the housing and connected to a wire. The thickness directions of the plurality of first extensions are aligned with each other, and the plurality of second extensions extend in a plane direction intersecting the mounting direction and orthogonal to the thickness direction.

[0025] According to this structure, the second extension of each terminal extends in a plane direction that intersects the assembly direction and is orthogonal to the thickness direction of the first extension. Therefore, the direction in which the wire connected to the second extension extends can be different from the assembly direction without bending the wire. Thus, interference between the wire and other components can be suppressed.

[0026] [2] Preferably, the plurality of terminals are embedded in the housing in a mutually separated state.

[0027] According to this structure, because an insulating resin shell is sandwiched between the terminals, the terminals can be electrically insulated from each other.

[0028] [3] Preferably, the plurality of the first extensions are arranged side by side in the surface direction, and the plurality of the second extensions are arranged side by side in the surface direction.

[0029] According to this structure, each of the first extensions and each of the second extensions are located on the same plane. Therefore, it is possible to suppress the increase in the size of the housing in the direction orthogonal to the aforementioned plane direction, i.e., in the thickness direction of the first extension, and consequently, the increase in the size of the connector.

[0030] [4] Preferably, the second extension that is furthest from the housing in the assembly direction among the plurality of second extensions has an inclined portion, the inclined portion being connected to the first extension and extending obliquely relative to the assembly direction, and the housing having an outer surface that extends along the inclined portion and covers the inclined portion.

[0031] According to this structure, compared to the case where the second extension furthest from the housing does not have an inclined portion, multiple terminals can be made smaller. Furthermore, the housing has an outer surface that extends along and covers the inclined portion, thus the housing can also be made smaller. Therefore, it is possible to suppress the increase in connector size.

[0032] [5] Preferably, each of the second extensions has a wire connection portion connected to the wire and a straight portion connected to the wire connection portion, and the multiple wire connection portions are arranged side by side in a direction orthogonal to the extension direction of the straight portion.

[0033] With this structure, multiple wire connectors are arranged side by side in a direction orthogonal to the extension direction of the straight section, thus making it easy to ensure that the lengths of the wires connected to each connector are the same. Therefore, it is possible to suppress the increase in the types of wires used in the connector.

[0034] [6] Preferably, the second extension has multiple wires connected to each of the terminals, each of the second extensions having a wire connection portion connected to each of the wires and a straight portion connected to the wire connection portion, each of the wire connection portions being covered by the housing, and each of the wires extending in the extension direction of the straight portion.

[0035] According to this structure, each wire connection is covered by the housing. Therefore, the housing can protect each wire connection. Furthermore, each wire extends from the housing in the direction of the straight section. Therefore, the wire connection is less likely to be subjected to load. Thus, the durability of the connector can be improved.

[0036] [7] Preferably, the housing has a metal shielding shell that covers the outer periphery of the portion of the housing that covers the plurality of terminals.

[0037] Based on this structure, electromagnetic shielding can be provided for each terminal covered by the housing.

[0038] [8] Preferably, each of the terminals has a third extension extending from the portion of the first extension on the housing side toward the plate thickness direction, each of the third extensions having a bolt hole through the third extension in the assembly direction, the housing having a cylindrical portion through the housing in the assembly direction and housing each of the third extensions, the cylindrical portion having an opening exposing each of the bolt holes.

[0039] According to this structure, bolts can be easily inserted into the bolt holes of the third extension housed in the cylindrical portion through the opening. Therefore, the third extension of the terminal and the connecting member located inside the housing can be easily fastened using bolts. Consequently, connector and device connection operations can be easily performed.

[0040] [Details of the embodiments of this disclosure]

[0041] The following is a reference to the appendix. Figure 1 Specific examples of the connectors described herein are illustrated below. In the accompanying drawings, for ease of illustration, portions of the structure are sometimes shown enlarged or simplified. Additionally, the dimensional ratios of the various parts sometimes differ in the drawings. Furthermore, this disclosure is not limited to these examples, but is intended, through the claims, to include all modifications within the meaning and scope equivalent to the claims. The term "orthogonal" in this specification includes not only strictly orthogonal cases, but also cases where they are substantially orthogonal to the extent that they achieve the desired effect in this embodiment.

[0042] like Figure 1 As shown, connector 10 is mounted on housing 101 of vehicle equipment 100, such as motors, inverters, etc.

[0043] An opening 102 for inserting a portion of the connector 10 and two fixing holes 103 for securing the connector 10 are provided on the outer surface of the housing 101. Three metal connecting members 104 protruding from the opening 102 are arranged side-by-side inside the housing 101. Each connecting member 104 protrudes beyond the outer surface of the housing 101. Each connecting member 104 has a threaded hole 105.

[0044] (Structure of connector 10)

[0045] like Figure 1 and Figure 2 As shown, connector 10 includes multiple terminals 20, multiple wires 30, a resin housing 40, and a metal shielding shell 80. Connector 10, for example, includes three terminals 20A, 20B, and 20C and three wires 30.

[0046] Each terminal 20, each wire 30, and the housing 40 are integrated by insert molding. Each terminal 20 and each wire 30 are embedded in the housing 40 in an electrically connected state. Multiple terminals 20 are embedded in the housing 40 in a separate state. Multiple wires 30 extend from the housing 40 in the same direction. The shielding shell 80 provides electromagnetic shielding for each terminal 20 and each wire 30 by covering a portion of the outer periphery of the housing 40.

[0047] From now on, the assembly direction of the connector 10 relative to the housing 101 will be referred to as the first direction Z, the direction in which each wire 30 extends will be referred to as the second direction X, and the direction orthogonal to both the first direction Z and the second direction X will be referred to as the third direction Y. In this embodiment, the first direction Z, the second direction X, and the third direction Y are orthogonal to each other.

[0048] (Structure of wire 30)

[0049] like Figure 3 As shown, the wire 30 has a core wire 31 and an insulating covering portion 32 that encloses the outer periphery of the core wire 31. The core wire 31 of the wire 30 has an exposed portion 31a that protrudes from the insulating covering portion 32 at the end of the wire 30. The exposed portion 31a is electrically connected to the terminal 20.

[0050] A water-stopping treatment is applied to the exposed portion 31a to prevent the core wire 31 from contacting water. In this embodiment, the water-stopping treatment involves applying an adhesive to the exposed portion 31a. The application of the adhesive prevents water from entering the housing 40, even if water has seeped into it. Furthermore, if the core wire 31 is a stranded wire composed of multiple metal wires twisted together, water can be prevented from seeping between the metal wires due to capillary action. In this embodiment, the exposed portion 31a functions as a coating portion where the adhesive is applied to the core wire 31 exposed from the insulation covering portion 32. It is not necessary to provide a coating portion on the wire 30.

[0051] For example, copper-based or aluminum-based metal materials can be used as the material for the core wire 31. For example, resin materials with cross-linked polyethylene or cross-linked polypropylene as the main component can be used as the material for the insulating sheath 32.

[0052] like Figure 2 As shown, multiple wires 30 are arranged side by side with intervals between each other in the first direction Z.

[0053] (Structure of terminal 20)

[0054] Terminal 20 is formed from a metal plate. The material of terminal 20 can be, for example, iron-based, copper-based, or aluminum-based metals.

[0055] Terminals 20A, 20B, and 20C are arranged in this order in the first direction Z at positions away from housing 101.

[0056] Terminals 20B and 20C have the same or corresponding structures as terminal 20A. The structure of terminal 20A, which is furthest from housing 101 in the first direction Z, will be described in detail below. In the structures of terminals 20B and 20C, structures identical to those of terminal 20A are labeled with the same reference numerals. For structures corresponding to terminal 20A, the last "A" in the reference numeral "2*A" representing the structure of terminal 20A is changed to "B" and "C" respectively, thus sometimes omitting redundant descriptions.

[0057] like Figure 4 As shown, terminal 20A has a first extension 21A, a second extension 22A and a third extension 26.

[0058] (Structure of the first extension 21A, 21B, 21C)

[0059] The first extension 21A extends in the first direction Z. The thickness direction of the first extension 21A is consistent with the third direction Y.

[0060] The thickness directions of the plurality of first extensions 21A, 21B, and 21C are consistent with each other. The plurality of first extensions 21A, 21B, and 21C are arranged side by side in the second direction X. The first extensions 21A, 21B, and 21C are formed in this order and are long.

[0061] (Structure of the second extension 22A, 22B, 22C)

[0062] The second extension 22A extends from the portion of the first extension 21A opposite to the housing 101. A wire 30 is connected to the second extension 22A. The thickness direction of the second extension 22A is aligned with the third direction Y.

[0063] Multiple second extensions 22A, 22B, and 22C extend in a planar direction that intersects the first direction Z and is orthogonal to the thickness direction of the first extension 21A. The second extensions 22A, 22B, and 22C are formed in this order and are elongated. Hereinafter, the planar direction orthogonal to the thickness direction of the first extension 21A will sometimes be referred to simply as the "planar direction".

[0064] The second extension 22A has a wire connection portion 23 connected to the exposed portion 31a of the wire 30, and a straight portion 24A connected to the wire connection portion 23. The exposed portion 31a is crimped to the wire connection portion 23. The straight portion 24A extends linearly in the second direction X. Therefore, the straight portion 24A extends orthogonally to the first extension 21A. Each wire 30 extends in the extension direction of each straight portion 24A, 24B, 24C, i.e., the second direction X.

[0065] Multiple wire connection portions 23 are arranged side by side in a direction orthogonal to the extension direction of the straight portion 24A, i.e., the first direction Z. Similarly, multiple straight portions 24A, 24B, and 24C are arranged side by side in the first direction Z.

[0066] The second extension 22A has an inclined portion 25A that connects the end of the first extension 21A and the end of the straight portion 24A. The inclined portion 25A is connected to the first extension 21A and extends obliquely relative to the first direction Z in the planar direction. The inclined portion 25A is inclined in such a way that the further away from the first extension 21A in the first direction Z, the closer to the straight portion 24A in the second direction X. The inclined portion 25A is longer than the inclined portion 25B.

[0067] Terminal 20C does not have a structure equivalent to the inclined portions 25A and 25B. That is, the second extension 22C of terminal 20C is formed by the wire connection portion 23 and the straight portion 24C. Therefore, in terminal 20C, the first extension 21C and the straight portion 24C are directly connected.

[0068] Based on the above, the plurality of first extensions 21A, 21B, and 21C are arranged side by side in the planar direction. Furthermore, the plurality of second extensions 22A, 22B, and 22C are also arranged side by side in the planar direction. That is, each of the first extensions 21A, 21B, and 21C and each of the second extensions 22A, 22B, and 22C are located on the same plane.

[0069] (Structure of the third extension 26)

[0070] The third extension 26 extends from the portion of the first extension 21A on the side of the housing 101 in the third direction Y. In other words, the third extension 26 extends orthogonally to the first extension 21A in the thickness direction from the portion of the first extension 21A opposite to the second extension 22A. The thickness direction of the third extension 26 is consistent with the first direction Z.

[0071] The thickness directions of the plurality of third extensions 26 are consistent with each other. The plurality of third extensions 26 are arranged side by side in the second direction X.

[0072] The third extension 26 has a bolt hole 27 through which it passes in the first direction Z. For example... Figure 5 As shown, the terminal 20 is electrically connected to the connecting member 104 by fastening the bolt 110 inserted into the bolt hole 27 to the threaded hole 105 of the connecting member 104.

[0073] (Structure of shell 40)

[0074] like Figure 2 As shown, the housing 40 has: a main body 50 that covers a plurality of terminals 20; and a plurality of protrusions 60 that protrude from the main body 50 in a second direction X and individually cover a plurality of wires 30. The housing 40 has, for example, three protrusions 60. The three protrusions 60 are spaced apart from each other in the arrangement direction of the plurality of wires 30, i.e., the first direction Z.

[0075] The housing 40 is formed of an insulating resin material. For example, a resin material such as polybutylene terephthalate (PBT) can be used as the material for the housing 40.

[0076] (Structure of main body 50)

[0077] like Figure 2 and Figure 3 As shown, the main body 50 has a cylindrical portion 51 that extends through in the first direction Z, and a retaining portion 53 that extends from the outer periphery of the cylindrical portion 51 in the first direction Z.

[0078] The cylindrical portion 51 houses each of the third extensions 26. The cylindrical portion 51 has an opening 51a that exposes each bolt hole 27. The opening 51a extends through the cylindrical portion 51 in the first direction Z. The opening 51a is formed as an elongated oval in the second direction X.

[0079] like Figure 5 As shown, an insertion part 52 is provided at one end of the cylindrical portion 51 in the first direction Z, and the insertion part 52 is inserted into the opening 102 of the housing 101. An annular sealing member 70 is provided on the outer peripheral surface of the insertion part 52. The insertion part 52 and the housing 101 are sealed by the sealing member 70.

[0080] Although the illustration is omitted, a maintenance cover that closes the opening 51a is fitted at the other end of the cylindrical portion 51 opposite to one end in the first direction Z.

[0081] like Figure 2 and Figure 5 As shown, the retaining part 53 extends from the outer periphery of the other end of the cylindrical part 51 toward the side opposite to the housing 101 in the first direction Z. The retaining part 53 covers a plurality of first extensions 21A, 21B, 21C and a plurality of second extensions 22A, 22B, 22C.

[0082] The retaining portion 53 has an outer surface 53a that extends along and covers the inclined portion 25A of the terminal 20A. The outer surface 53a extends in a plane direction orthogonal to the direction in which the inclined portion 25A extends.

[0083] (Structure of protrusion 60)

[0084] like Figure 2 As shown, each protrusion 60 has: a first portion 61, with an insulating covering portion 32 and an exposed portion 31a for embedding the wire 30; and a second portion 62, with an embedded wire connection portion 23. The wire 30 extends from the first portion 61 in a second direction X. The second portion 62 protrudes from the end of the holding portion 53 in a second direction X. Each first portion 61 protrudes from the end of the second portion 62 in a second direction X.

[0085] like Figure 6 As shown, the cross-sectional shape of the first part 61, orthogonal to the second direction X, is, for example, circular. The cross-sectional shape of the second part 62, orthogonal to the second direction X, is, for example, quadrilateral. The thickness of the second part 62 in the first direction Z is greater than the thickness of the first part 61 in the first direction Z. The thickness of the second part 62 in the third direction Y is slightly greater than the thickness of the first part 61 in the first direction Z.

[0086] (Structure of the first connecting part 63 and the second connecting part 64)

[0087] like Figure 2 As shown, the housing 40 has: a plurality of first connecting portions 63 that connect two adjacent first portions 61 in the first direction Z; and a plurality of second connecting portions 64 that connect two adjacent second portions 62 in the first direction Z. The housing 40 has, for example, two first connecting portions 63 and two second connecting portions 64.

[0088] From now on, two adjacent first parts 61 in the first direction Z will be referred to as "two first parts 61", and two adjacent second parts 62 in the first direction Z will be referred to as "two second parts 62".

[0089] The first connecting portion 63 is disposed in the second direction X at a position away from the second part 62. More specifically, the first connecting portion 63 is disposed at a position closer to the top end 60c than the intermediate portion 60b between the base end 60a and the top end 60c of the protrusion 60 in the second direction X. Therefore, the first connecting portion 63 partially connects the two first parts 61. In addition, the base end 60a is formed by the second part 62. The intermediate portion 60b and the top end 60c are formed by the first part 61.

[0090] An insulating covering portion 32 of the wire 30 is embedded in the portion of the protrusion 60 that is closer to the top end 60c than the middle portion 60b. Therefore, the first connecting portion 63 connects the portions of the two first portions 61 in which the insulating covering portion 32 is embedded to each other.

[0091] like Figure 6 As shown, the first connecting portion 63 is located inside the outer surfaces 61a on both sides of each of the first portions 61 in the third direction Y. Therefore, the thickness of the first connecting portion 63 in the third direction Y is less than the thickness of the first portion 61 in the third direction Y.

[0092] like Figure 2 As shown, the second connecting portion 64 is positioned away from the retaining 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 positioned between the retaining portion 53 and the first connecting portion 63 in the second direction X. The second connecting portion 64 connects the portions of each of the two second portions 62 in which the embedded wire connection portion 23 is located to each other.

[0093] like Figure 7 As shown, the second connecting portion 64 is located inside the outer surfaces 62a on both sides of each of the second portions 62 in the third direction Y. Therefore, the thickness of the second connecting portion 64 in the third direction Y is less than the thickness of the second portion 62 in the third direction Y.

[0094] (Structure of shielding shell 80)

[0095] like Figure 1 and Figure 8 As shown, the shielding shell 80 covers the housing 40 from one of the third directions Y. The shielding shell 80 has: a first shielding portion 81 that covers the portion of the cylindrical portion 51 except for the insertion portion 52; and a second shielding portion 83 that covers the retaining portion 53 and each of the second portions 62. The first shielding portion 81 and the second shielding portion 83 are formed integrally.

[0096] The material used for the shielding shell 80 can be, for example, iron-based or aluminum-based metals.

[0097] like Figure 1As shown, fixing parts 82 are provided on both sides of the first shielding part 81 in the second direction X, and the fixing parts 82 are fixed to the housing 101. A through hole 82a is provided in the fixing part 82, penetrating in the first direction Z. The shielding shell 80 is fixed to the housing 101 by fastening it with bolts 120 inserted into the through holes 82a and fastened to the fixing holes 103 of the housing 101.

[0098] The second shielding part 83 has an outer surface 83a extending along the outer surface 53a of the housing 40. Two mounting parts 84 are provided at one end of the second shielding part 83 in the second direction X, and female threads are formed in the two mounting parts 84.

[0099] Although not shown in the diagram, the assembly section 84 is fitted with a metal cylindrical support that covers multiple first parts 61 together. Additionally, a braided component formed by weaving metal wires is fitted onto this support.

[0100] The function of this embodiment will be explained.

[0101] The second extensions 22A, 22B, and 22C of each terminal 20 extend in a surface direction that intersects the first direction Z and is orthogonal to the thickness direction of the first extensions 21A, 21B, and 21C. Therefore, the direction in which the wires 30 connected to each of the second extensions 22A, 22B, and 22C are extended is different from the first direction Z, which is the assembly direction of the connector 10, without bending the wires 30.

[0102] The effects of this implementation method will be explained.

[0103] (1) The connector 10 comprises a plurality of terminals 20 formed by a metal plate and extending side by side, and a resin housing 40 covering the plurality of terminals 20, and is assembled into the housing 101 of the device 100. The terminals 20A, 20B, and 20C each have: first extensions 21A, 21B, and 21C extending in the first direction Z; and second extensions 22A, 22B, and 22C extending from a portion of the first extensions 21A, 21B, and 21C opposite to the housing 101 and connected to a wire 30. The thickness directions of the plurality of first extensions 21A, 21B, and 21C are aligned with each other. The plurality of second extensions 22A, 22B, and 22C extend in a plane direction orthogonal to the first direction Z and orthogonal to the aforementioned thickness direction.

[0104] Based on this structure, the aforementioned function is achieved. Therefore, even if there are other components different from connector 10 on the side opposite to housing 101 across connector 10, interference of wire 30 with other components can be suppressed.

[0105] (2) Multiple terminals 20 are embedded in the housing 40 in a mutually separated state.

[0106] With this structure, because an insulating resin housing 40 is sandwiched between the terminals 20, the terminals 20 can be electrically insulated from each other.

[0107] (3) Multiple first extensions 21A, 21B, and 21C are arranged side by side in the surface direction, and multiple second extensions 22A, 22B, and 22C are arranged side by side in the surface direction.

[0108] With this structure, the first extensions 21A, 21B, 21C and the second extensions 22A, 22B, 22C are located on the same plane. Therefore, it is possible to suppress the increase in the size of the housing 40 in the direction orthogonal to the plane direction, i.e., in the thickness direction of the first extensions 21A, 21B, 21C, and consequently the increase in the size of the connector 10.

[0109] (4) Of the plurality of second extensions 22A, 22B, and 22C, the second extension 22A that is furthest from the housing 101 in the first direction Z has an inclined portion 25A. The inclined portion 25A is connected to the first extension 21A and extends obliquely relative 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.

[0110] With this structure, compared to the case where the second extension 22A does not have the inclined portion 25A, the multiple terminals 20 can be made smaller. Furthermore, the housing 40 has an outer surface 53a that extends along and covers the inclined portion 25A, thus the housing 40 can also be made smaller. Therefore, it is possible to suppress the increase in the size of the connector 10.

[0111] (5) The second extensions 22A, 22B, and 22C each have a wire connection portion 23 connected to the wire 30 and a straight portion 24A, 24B, and 24C connected to the wire connection portion 23. The multiple wire connection portions 23 are arranged side by side in a direction orthogonal to the extension direction of the straight portions 24A, 24B, and 24C.

[0112] With this structure, multiple wire connection portions 23 are arranged side by side in a direction orthogonal to the extending directions of straight portions 24A, 24B, and 24C, thus making it easy to ensure that the lengths of the wires 30 connected to each wire connection portion 23 are the same. Therefore, it is possible to suppress the increase in the types of wires 30 used in the connector 10.

[0113] (6) The connector 10 has multiple wires 30 that connect to each terminal 20. Each wire connection portion 23 is embedded in the housing 40. Each wire 30 extends in the extension direction of the straight portions 24A, 24B, and 24C.

[0114] With this structure, each wire connection portion 23 is embedded in the housing 40. Therefore, the housing 40 can protect each wire connection portion 23. Furthermore, each wire 30 extends from the housing 40 in the direction of the straight portions 24A, 24B, and 24C. Therefore, the wire connection portions 23 are less likely to be subjected to load. Thus, the durability of the connector 10 can be improved.

[0115] (7) The connector 10 has a metal shield 80 that covers the outer periphery of the portion of the housing 40 that covers a plurality of terminals 20.

[0116] With this structure, electromagnetic shielding can be provided for each terminal 20 embedded in the housing 40.

[0117] (8) Terminals 20A, 20B, and 20C each have a third extension 26 extending from the portion of the first extension 21A, 21B, and 21C on the housing 101 side in the plate thickness direction. The third extension 26 has a bolt hole 27 through which the third extension 26 passes in the first direction Z. The housing 40 has a cylindrical portion 51 through which the housing 40 passes in the first direction Z and houses each of the third extensions 26. The cylindrical portion 51 has an opening 51a exposing each bolt hole 27.

[0118] With this structure, the bolt 110 can be easily inserted into the bolt hole 27 of the third extension 26 housed in the cylindrical portion 51 through the opening 51a. Therefore, the third extension 26 and the connecting member 104 provided inside the housing 101 can be easily fastened using the bolt 110. Thus, the connection operation between the connector 10 and the device 100 can be easily performed.

[0119] (9) Each wire 30 has a core wire 31 and an insulating covering portion 32 that covers the outer periphery of the core wire 31. The exposed portion 31a of the core wire 31, which protrudes from the end of the insulating covering portion 32, is connected to each terminal 20. The insulating covering portion 32 and the exposed portion 31a in each 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 in which the insulating covering portion 32 is embedded to each other.

[0120] In a connector with a housing 40 containing embedded wires 30, a coating portion is provided to apply adhesive to the core wires 31 exposed from the insulating cover portion 32 in order to prevent water from entering between the wires 30 and the housing 40. When the portions of two adjacent protrusions 60 in which the coating portions are embedded are connected to each other by a connecting portion, during the injection molding of the housing 40, the protrusions 60 shrink thermally as they approach the connecting portion, making it possible for the adhesive to peel off from the core wires.

[0121] In this respect, according to the above structure, since the first connecting part 63 connects the portions of the two first parts 61 in which the insulating covering part 32 is embedded, the above-mentioned adverse situation is less likely to occur.

[0122] <Example of Change>

[0123] This embodiment can be modified and implemented as follows. This embodiment and the following modifications can be combined and implemented within the scope of technical inconsistency.

[0124] Each third extension 26 may also extend in the first direction Z in the planar direction. In this case, the axial direction of each bolt hole 27 is orthogonal to the planar direction. In such a connector, for example, each third extension 26 and each connecting member 104 are bolted together in the third direction Y.

[0125] The connection between the third extension 26 and the connecting member 104 is not limited to bolt fastening. Alternatively, for example, the third extension 26 and the connecting member 104 can be clamped using a spring member or the like while they are overlapping.

[0126] It can also replace the shielding shell 80, and cover the shell 40 with a braided component formed by braided metal wire.

[0127] For example, when the voltage loaded on connector 10 is low, the shield 80 can be omitted from connector 10.

[0128] • Each wire connection 23 may also be exposed from the housing 40. In this case, various insulation and waterproofing treatments may be applied to each wire connection 23.

[0129] • Each wire connection part 23 may also be arranged side by side in the plane direction and in the direction that intersects with the first direction Z.

[0130] • The outer surface 53a of the housing 40 may not extend along the inclined portion 25A.

[0131] The multiple second extensions 22A, 22B, and 22C may not be arranged side-by-side in the planar direction. For example, the multiple second extensions 22A, 22B, and 22C may also be arranged side-by-side in a direction intersecting the planar direction. Such a structure can be achieved, for example, by making the lengths of the third extensions 26 different.

[0132] • The connector 10 in this embodiment is a connector in which each terminal 20 and each wire 30 are embedded in the housing 40. However, the connector 10 may also be a connector in which each terminal 20 and each wire 30 are covered by a housing having multiple segments assembled with each other.

[0133] The straight sections 24A, 24B, and 24C can be any straight sections that extend obliquely relative to the first extensions 21A, 21B, and 21C in the surface direction. The angle formed by each of the straight sections 24A, 24B, and 24C and the first extensions 21A, 21B, and 21C can be set to any angle, such as 100°. In this case, each protrusion 60 can also be obliquely at any of the aforementioned angles relative to the first direction Z.

[0134] The number of terminals 20 and wires 30 can be appropriately changed according to the specifications of connector 10.
