[0028] [Description of embodiments of this disclosure]

[0029] First, the implementation methods of this disclosure are listed and explained.

[0030] [1] The connector disclosed herein has: a plurality of terminals, which are respectively connected to the ends of a plurality of wires; an annular connector housing that houses the plurality of terminals; an inner member that is assembled at the end of the connector housing; a plurality of through holes that are disposed in the inner member, and the plurality of wires individually pass through the plurality of through holes; a plurality of annular first sealing members that are individually fitted into the inner side of the plurality of through holes; and annular second sealing members that are fitted into the outer side of the inner member, wherein the first sealing members are in close contact with the outer peripheral surface of the wires and the inner peripheral surface of the through holes, and the second sealing members are in close contact with the outer peripheral surface of the inner member and the inner peripheral surface of the connector housing.

[0031] According to this structure, the inner component at the end assembled to the connector housing has multiple through holes through which multiple wires pass individually. Furthermore, multiple first sealing members are individually fitted into these through holes. Therefore, for example, by installing the first sealing member individually for each wire and inserting the wire with the first sealing member installed into the through hole of the inner component, the wire and the first sealing member can be assembled into the inner component. Thus, the first sealing member can be installed individually for each wire, thereby improving the workability of installing the first sealing member on the wires compared to installing multiple wires on a single rubber plug. This improves the assembly workability of the connector.

[0032] However, in existing connectors, when only sealing members are installed for each wire individually, gaps arise between adjacent sealing members in the direction of multiple wire arrangement, thus failing to seal the connector housing and the wires. In contrast, the above structure includes an inner member with multiple through holes, a first sealing member that is in close contact with the inner circumferential surface of the through holes and the outer circumferential surface of the wires, and a second sealing member that is in close contact with the outer circumferential surface of the inner member and the inner circumferential surface of the connector housing. Through these inner members, the first sealing member, and the second sealing member, the outer circumferential surface of the wires is sealed to the inner circumferential surface of the inner member, and the outer circumferential surface of the inner member is sealed to the inner circumferential surface of the connector housing. This prevents liquids such as water from seeping into the interior of the connector housing from its ends. Thus, by providing an inner member with multiple through holes, the connector's assembly operability is improved, and the connector's waterproofness is maintained.

[0033] [2] Preferably, it further includes a stop body fitted to the end of the connector housing to prevent the inner component and the first sealing member from detaching from the connector housing. According to this structure, the stop body can prevent the inner component and the first sealing member from detaching from the connector housing. Thus, the waterproofness of the connector can be appropriately maintained.

[0034] [3] Preferably, the inner member has a first engaging portion that engages with the connector housing, and the stop has a second engaging portion that engages with the connector housing. The first engaging portion is located at a different position in the circumferential direction of the connector housing than the second engaging portion. According to this structure, the first engaging portion of the inner member and the second engaging portion of the stop are located at different positions in the circumferential direction of the connector housing. Therefore, the first engaging portion and the second engaging portion are located in a non-overlapping position in the radial direction of the connector housing. Therefore, compared to the case where the first engaging portion and the second engaging portion overlap in the radial direction of the connector housing, the connector can be miniaturized in the radial direction of the connector housing.

[0035] [4] Preferably, the stop is constructed from a pair of split bodies, each of the split bodies having a third engaging portion, a fourth engaging portion, and a fifth engaging portion disposed inside the stop. The third engaging portion of one of the split bodies engages with the fourth engaging portion of the other split body, and the fifth engaging portion of one split body engages with the fifth engaging portion of the other split body. According to this structure, the stop is constructed from a pair of split bodies. Therefore, for example, after the wire is inserted into the connector housing, the stop can be assembled to the end of the connector housing. This improves the workability of assembling the stop in the connector housing and enhances the assembly workability of the connector. Furthermore, the pair of split bodies engage at the third, fourth, and fifth engaging portions. Therefore, the pair of split bodies can be securely engaged, and separation of the pair of split bodies can be appropriately suppressed. This appropriately suppresses the stop from detaching from the connector housing. Furthermore, because the fifth engaging portion is located inside the stop body, it does not protrude outside the stop body. Therefore, it prevents operators from accidentally disengaging the fifth engaging portion. Consequently, it prevents the separation of the pair of split bodies and the stop body from detaching from the connector housing.

[0036] [5] Preferably, each of the pair of said segments has: an opposing surface, opposite to the other segment; a recess, recessed from the opposing surface; and an elastic sheet capable of elastic deformation, protruding from the bottom surface of the recess toward the other segment, the fifth engaging portion being provided at the top end of the elastic sheet. According to this structure, the elastic sheet with the fifth engaging portion provided at the top end protrudes from the bottom surface of the recess provided on the opposing surface toward the other segment. Therefore, compared to, for example, a structure without a recess, that is, a structure with an elastic sheet provided on the opposing surface, the space in which the elastic sheet can be flexed can be formed to be wider, and the large size of the stop body can be suppressed. Here, "opposing" in this specification means a position where the surfaces or components are facing each other, including not only the case where they are completely facing each other, but also the case where they are partially facing each other. In addition, "opposing" in this specification includes both the case where a component separate from the two parts is sandwiched between the two parts and the case where nothing is sandwiched between the two parts.

[0037] [6] Preferably, the stop body has multiple wire-through holes through which multiple wires pass individually, and each of the multiple wire-through holes has a protrusion that protrudes radially inward from the inner circumference of the wire-through hole towards the wire-through hole. According to this structure, a protrusion protruding from the inner circumference of each wire-through hole towards the radially inward side of the wire-through hole, i.e., from the wire passing through the wire-through hole, is provided on the inner circumferential surface of each wire-through hole. This protrusion can appropriately support the wire passing through the wire-through hole, thus appropriately suppressing the wobbling of the wire inside the wire-through hole. Therefore, for example, relative movement between the terminal connected to the end of the wire and the other terminal can be appropriately suppressed. As a result, contact wear between the terminal and the other terminal can be appropriately suppressed.

[0038] [7] Preferably, the plurality of wire through holes have a first wire through hole and a second wire through hole, the fifth engaging portion is disposed between the first wire through hole and the second wire through hole in the direction in which the first wire through hole and the second wire through hole are arranged, the first wire through hole is disposed between the third engaging portion and the fifth engaging portion in one of the partitions in the direction in which the first wire through hole and the second wire through hole are arranged, and the second wire through hole is disposed between the fourth engaging portion and the fifth engaging portion in one of the partitions in the direction in which the first wire through hole and the second wire through hole are arranged. According to this structure, the first wire through hole is disposed between the third engaging portion and the fifth engaging portion in one of the partitions, and the second wire through hole is disposed between the fourth engaging portion and the fifth engaging portion in one of the partitions. That is, the first wire through hole and the second wire through hole are configured to be sandwiched between two engaging portions in a pair of partitions. Therefore, compared to the case where only one engaging portion is provided near the first and second wire through holes, the pair of segments in the first and second wire through holes can be securely engaged. Consequently, the pair of segments can be appropriately brought close to each other in the first and second wire through holes, and the protrusions provided on the inner circumferential surfaces of the first and second wire through holes can stably support the wires. Therefore, the wobbling of the wires inside the first and second wire through holes can be appropriately suppressed.

[0039] [8] Preferably, the pair of said segments have the same shape. According to this structure, since the pair of segments are formed with the same shape, the increase in the number of parts, specifically the types of parts, can be suppressed.

[0040] [9] Preferably, the connector housing has: an inner housing for housing a plurality of said terminals; and an outer housing for housing the inner housing, the inner housing and the outer housing being separate components, the inner member being assembled to the end of the outer housing and supporting the inner housing inside the outer housing. According to this structure, the inner housing housing the terminals is supported by the inner member inside the outer housing. Therefore, when vibration is applied to the connector, shaking of the inner housing inside the outer housing can be suppressed. Consequently, relative movement of the terminals housed in the inner housing relative to the other terminals can be suppressed, and contact wear between the terminals and the other terminals can be appropriately suppressed.

[0041]

[10] Preferably, the inner housing has a base and a plurality of terminal receiving portions extending from the base, wherein the plurality of terminal receiving portions individually receive the plurality of terminals, and the plurality of terminal receiving portions are formed integrally through the base, and the inner member contacts the base to support the inner housing. According to this structure, the plurality of terminal receiving portions are formed integrally through the base. Therefore, compared with the case where the plurality of terminal receiving portions are composed of separate parts, the number of parts can be reduced. In addition, the plurality of terminal receiving portions can be supported by the contact between the inner member and the base. Therefore, compared with the case where a structure for supporting the plurality of terminal receiving portions is provided separately, the structure of the inner member can be simplified.

[0042]

[11] The wire harness of this disclosure has a connector as described in any one of [1] to

[10] above, and a plurality of wires respectively connected to the plurality of terminals. According to this structure, by providing an internal component with a plurality of through holes, the assembly workability of the wire harness can be improved, and the waterproofness of the wire harness can be maintained.

[0043] [Details of the embodiments of this disclosure]

[0044] The following is a reference to the appendix. Figure 1 Specific examples of the connectors and wire harnesses disclosed herein are described below. In the accompanying drawings, for ease of description, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the various drawings. The terms "parallel" and "orthogonal" in this specification include not only cases where they are strictly parallel or orthogonal, but also cases where they are substantially parallel or orthogonal to the extent that they achieve the desired effect in this embodiment. Moreover, the invention is not limited to these examples, but as indicated by the claims, it is intended to include all modifications within the meaning and scope equivalent to the claims.

[0045] (Overall structure of wire harness 10)

[0046] Figure 1 The wiring harness 10 shown electrically connects two or more (two in this embodiment) on-board devices 11 and 12. The wiring harness 10 and the on-board devices 11 and 12 are installed in a vehicle V, such as a hybrid vehicle or an electric vehicle. For example, the wiring harness 10 electrically connects on-board device 11 located at the front of the vehicle V and on-board device 12 located at the rear of the vehicle V, beyond on-board device 11. Examples of on-board devices 11 and 12 include, for example, high-voltage batteries, inverters, electric motors, and relay boxes.

[0047] like Figure 2 and Figure 3 As shown, the wire harness 10 has, for example, one or more (two in this embodiment) wires 20 and connector assemblies C1 fitted to the ends of the wires 20.

[0048] (Overall structure of connector assembly C1)

[0049] Connector assembly C1 includes a connector 30 and a connector 200 detachable from the connector 30. The connector 30 has a plurality of metal terminals 31 (two in this embodiment). The connector 200 has a plurality of metal terminals 201 (two in this embodiment) and a connector housing 202 holding the terminals 201. The connector 30 and connector 200 are assembled to each other along an assembly direction D1. For example, the connector 30 engages with the connector 200 along the assembly direction D1. Figure 3 As shown, when connector 30 is properly engaged with connector 200, terminals 31 and 201 are electrically connected to each other. Connector 200 is, for example, fixed to vehicle-mounted devices 11 and 12 (see reference). Figure 1 The assembly objects include the outer shell of the connector 30 and the connector 200. Furthermore, the assembly direction D1 indicates the relative assembly direction of the connector 30 with respect to the connector 200, and does not limit the connector 200 to a fixed side. Additionally, the up and down directions in the accompanying drawings do not necessarily indicate the posture of the connector 30 and connector 200 during use.

[0050] In the following description of the positional relationships of the constituent elements of connector 30, the direction consistent with the assembly direction D1 will be referred to as the first direction X1, and the direction opposite to the first direction X1 will be referred to as the first opposite direction X2. Furthermore, among the directions orthogonal to the first direction X1, the direction in... Figure 3 The direction pointing upwards is called the second direction Y1, and the direction opposite to the second direction Y1 is called the second opposite direction Y2. Among the directions orthogonal to both the first direction X1 and the second direction Y1, in... Figure 3 The direction to the left of the center is called the third direction Z1, and the opposite direction of the third direction Z1 is called the third opposite direction Z2. Furthermore, the description of the directions in connector 200 is based on the state in which connector 30 is assembled in connector 200.

[0051] (Structure of connector 30)

[0052] like Figure 4As shown, the connector 30 has a plurality of terminals 31 respectively connected to the ends of a plurality of wires 20 and an annular connector housing 40 for housing the plurality of terminals 31. The connector housing 40 has an inner housing 41 for housing the terminals 31 and an outer housing 50 covering the inner housing 41. The connector 30 has, for example, one or more (two in this embodiment) conductive clamping members 60 fitted to the wires 20 and conductive, and one or more (two in this embodiment) conductive leaf springs 70. The connector 30 has an inner shell 80 covering the clamping members 60 and conductive, and an inner member 90 supporting the inner shell 41. The connector 30 has, for example, a plurality of (two in this embodiment) sealing members 100 fitted into the inner side of the inner member 90, a sealing member 110 fitted into the outer side of the inner member 90, and a stop 120 for preventing the sealing members 100 from detaching.

[0053] (Structure of wire 20)

[0054] like Figure 5 and Figure 6 As shown, each wire 20 has: a conductive core wire 21; and an insulating sheath 22 surrounding the core wire 21. Each wire 20 also has: a conductive electromagnetic shielding member 23 surrounding the sheath 22; and an insulating covering 24 surrounding the electromagnetic shielding member 23. Each wire 20 is, for example, a shielded wire with its own electromagnetic shielding structure.

[0055] As the core wire 21, for example, a stranded wire made of multiple metal wires twisted together, a cylindrical conductor consisting of a single metal rod with a solid internal structure, or a cylindrical conductor with a hollow internal structure can be used. Alternatively, stranded wire, cylindrical conductor, and tubular conductor can be combined as the core wire 21. As the material of the core wire 21, for example, copper-based or aluminum-based metal materials can be used.

[0056] The sheath 22, for example, covers the entire circumference of the outer periphery of the core wire 21. The sheath 22 is, for example, made of an insulating resin material.

[0057] The electromagnetic shielding member 23, for example, surrounds the outer peripheral surface of the sheath 22 throughout its entire circumference. The electromagnetic shielding member 23, for example, is flexible. As the electromagnetic shielding member 23, for example, multiple metal wires can be braided into a cylindrical shape or metal foil can be used. In this embodiment, the electromagnetic shielding member 23 is a braided wire. As the material for the electromagnetic shielding member 23, for example, copper-based, aluminum-based, or other metallic materials can be used.

[0058] The insulating covering portion 24, for example, surrounds the entire circumference of the outer peripheral surface of the electromagnetic shielding member 23. The insulating covering portion 24 is, for example, made of an insulating resin material.

[0059] The end of the core wire 21 in the second direction Y1 protrudes from the sheath 22. A terminal 31 is connected to the end of the core wire 21 exposed from the sheath 22. The end of the electromagnetic shielding member 23 in the second direction Y1 protrudes from the insulating cover portion 24. A clamping member 60 is connected to the end of the electromagnetic shielding member 23 exposed from the insulating cover portion 24.

[0060] (Structure of terminal 31)

[0061] like Figure 4 As shown, the two terminals 31 are electrically connected to the two wires 20 respectively. Each terminal 31 has, for example, a wire connection portion 32 and a terminal connection portion 33 that are connected to the end of the wire 20. Each terminal 31 is, for example, a single component in which the wire connection portion 32 and the terminal connection portion 33 are formed as one piece. As the material for each terminal 31, metal materials such as copper, copper alloy, aluminum, aluminum alloy, and stainless steel can be used.

[0062] The wire connection portion 32 is connected to the end of the core wire 21 exposed from the sheath 22. The wire connection portion 32 is, for example, formed in a flat plate shape. The wire connection portion 32 is connected to the core wire 21, for example, by crimping, ultrasonic welding, or the like. Thus, the wire connection portion 32 and the core wire 21 are electrically and mechanically connected.

[0063] The terminal connection portion 33 is, for example, formed in the shape of a flat plate. Figure 3 As shown, the terminal connection part 33 is electrically and mechanically connected to the terminal 201 of the connector 200.

[0064] (Structure with clamping component 60)

[0065] like Figure 4 As shown, the two clamping components 60 are respectively assembled onto the two wires 20. Figure 5 As shown, each clamping member 60 is fitted to the outer periphery of the end of the electromagnetic shielding member 23 exposed from the insulating cover portion 24. Each clamping member 60 is formed in a ring shape. Each clamping member 60 is formed in a ring shape along the outer peripheral surface of the wire 20. The outer periphery of each clamping member 60 is surrounded, for example, by the outer shell 50 and the inner shell 80. Each clamping member 60 is in contact with each electromagnetic shielding member 23 and with the inner shell 80. Each clamping member 60 electrically connects each electromagnetic shielding member 23 and the inner shell 80. As the material for each clamping member 60, copper-based or aluminum-based metal materials can be used, for example.

[0066] One axial end of each clamping member 60 is connected to the outer peripheral surface of the electromagnetic shielding member 23, for example, via a fixing member 61. The fixing member 61 fixes the clamping member 60 to the outer peripheral surface of the wire 20 while the clamping member 60 is in contact with the electromagnetic shielding member 23. The fixing member 61 is formed in a ring shape along the outer peripheral surface of the wire 20. The fixing member 61 is fitted onto the outside of the wire 20 such that one axial end of the clamping member 60 is sandwiched between the outer peripheral surface of the electromagnetic shielding member 23 and the wire 20. Furthermore, by tightening the fixing member 61 radially inward towards the wire 20, one axial end of the clamping member 60 is secured and fixed in direct contact with the outer peripheral surface of the electromagnetic shielding member 23. Thus, the electromagnetic shielding member 23 and the clamping member 60 are electrically and mechanically connected to each other. For example, a fastening ring or a fastening band can be used as the fixing member 61.

[0067] (Structure of leaf spring 70)

[0068] like Figure 4 As shown, two leaf springs 70 are respectively provided with two wires 20. Iron-based or copper-based metal materials can be used as the material for each leaf spring 70. The planar shape of each leaf spring 70 viewed from the second direction Y1 is U-shaped.

[0069] (Structure of inner shell 41)

[0070] The inner housing 41, for example, has a base 42 and a terminal receiving portion 43 extending from the base 42 in a second direction Y1. The inner housing 41 is, for example, made of an insulating resin material. The inner housing 41 is, for example, a separate component from the outer housing 50.

[0071] like Figure 7 As shown, a base 42 is located at the end of the inner housing 41 on the side opposite to the second direction Y2. The base 42 is formed in an annular shape. The base 42 has, for example, two through holes 42X through which two wires 20 pass individually. Each through hole 42X passes through the base 42 in the second direction Y1. The base 42 has a partition wall 44 that separates the two through holes 42X. The partition wall 44 is disposed between the two through holes 42X in the third direction Z1. The partition wall 44 extends, for example, along the entire length of the base 42 in the second direction Y1.

[0072] The terminal housing 43 houses two terminals 31. For example, the terminal housing 43 is provided corresponding to each of the two terminals 31. That is, the inner housing 41 has two terminal housings 43. The two terminal housings 43 are spaced apart in the third direction Z1. The two terminal housings 43 are connected to a base 42. In other words, the two terminal housings 43 are formed integrally through the base 42.

[0073] Each terminal housing portion 43 is, for example, formed as a box extending from the base 42 along the second direction Y1. In other words, each terminal housing portion 43 is, for example, formed as a bottomed ring with a bottom wall 45. The bottom wall 45 is formed by the peripheral wall of the terminal housing portion 43 in the second direction Y1. The internal space of each terminal housing portion 43 communicates with each through hole 42X of the base 42. A terminal 31 is housed within the internal space of each terminal housing portion 43. Each terminal housing portion 43 has an insertion hole 46 into which a terminal 201 of the connector 200 (see reference) is inserted. Figure 2 Each insertion hole 46 communicates with the internal space of each terminal storage section 43.

[0074] (Structure of outer shell 50)

[0075] like Figures 4-6 As shown, the outer shell 50 surrounds the outer periphery of the inner shell 41. In other words, the inner shell 41 is housed inside the outer shell 50. The outer shell 50 is, for example, formed as a bottomed annular shape with a bottom wall 51. For example, the outer shell 50 is formed as a bottomed annular shape with an opening in the second opposite direction Y2 and an opening in the second direction Y1 closed by the bottom wall 51. Figure 4 As shown, the outer casing 50 has a bottom wall 51, a peripheral wall 52 disposed in the first direction X1, a peripheral wall 53 disposed in the first opposite direction X2, a peripheral wall 54 disposed in the third opposite direction Z2, and a peripheral wall 55 disposed in the third direction Z1.

[0076] The housing 50 has an opening 50X that exposes the insertion hole 46 of the terminal receiving portion 43. The opening 50X is provided in the peripheral wall 52 of the housing 50 in a first direction X1. The opening 50X is also provided at the end of the peripheral wall 52 on the second direction Y1 side, that is, the end on the bottom wall 51 side of the peripheral wall 52. The opening 50X penetrates the peripheral wall 52 along the first direction X1, which is parallel to the assembly direction D1. The opening 50X communicates with the internal space of the housing 50.

[0077] The outer peripheral surface of the outer shell 50 has one or more (four in this embodiment) engaging portions 56, one or more (two in this embodiment) engaging portions 57, and one or more (two in this embodiment) engaging portions 58.

[0078] The engaging portion 56 is provided, for example, on the outer surface of the end portion of the peripheral wall 52 on the second opposite direction Y2 side. In this embodiment, two engaging portions 56 are provided on the outer surface of the peripheral wall 52 at the end portion on the second opposite direction Y2 side. The two engaging portions 56 are provided separately from each other, for example, in the third direction Z1. Each engaging portion 56 is formed, for example, to protrude radially outward from the outer surface of the peripheral wall 52 toward the outer surface of the housing 50.

[0079] The engaging portion 57 is, for example, provided on the outer surface of the end portion of the peripheral wall 52 on the second opposite direction Y2 side. In this embodiment, an engaging portion 57 is provided on the outer surface of the peripheral wall 52 at the end portion on the second opposite direction Y2 side. One engaging portion 57 is provided in the third direction Z1 at a position offset from the two engaging portions 56. One engaging portion 57 is provided in the third direction Z1 between the two engaging portions 56. One engaging portion 57 is provided in the second direction Y1 at a position offset from the two engaging portions 56. One engaging portion 57 is, for example, provided on the second opposite direction Y2 side than the two engaging portions 56. One engaging portion 57 is formed, for example, in a manner that protrudes radially outward from the outer surface of the peripheral wall 52 towards the outer surface of the housing 50. Furthermore, as Figure 3 As shown, two engaging parts 56 and one engaging part 57 are also provided on the peripheral wall 53.

[0080] The engaging portion 58 is provided, for example, on the outer surface of the end portion of the peripheral wall 54 on the second opposite direction Y2 side. In this embodiment, an engaging portion 58 is provided on the outer surface of the peripheral wall 54 at the end portion on the second opposite direction Y2 side. One engaging portion 58 is provided in the second direction Y1 at a position offset from the two engaging portions 56. One engaging portion 58 is provided, for example, on the second opposite direction Y2 side, closer to the two engaging portions 56. One engaging portion 58 is provided, for example, in the second direction Y1 at the same position as one engaging portion 57. One engaging portion 58 is formed, for example, in a manner that protrudes radially outward from the outer surface of the peripheral wall 54 towards the outer surface of the housing 50. Furthermore, although not shown in the figure, an engaging portion 58 is also provided on the peripheral wall 55.

[0081] (Structure of inner shell 80)

[0082] like Figure 4 As shown, the inner shell 80 is formed, for example, into a ring extending in the second direction Y1. For example, copper-based, aluminum-based, or ferrous metals can be used as the material for the inner shell 80.

[0083] like Figure 5 and Figure 6 As shown, the inner shell 80 is housed inside the outer shell 50. The inner shell 80 is radially disposed between the inner circumferential surface of the outer shell 50 and the outer circumferential surface of the inner shell 41 and the outer circumferential surface of the clamping member 60. The end of the inner shell 80 in the second opposite direction Y2 contacts the outer circumferential surface of the clamping member 60. Thus, the inner shell 80 is electrically connected to the clamping member 60.

[0084] (Structure of internal component 90)

[0085] like Figure 8As shown, the inner member 90 is assembled to the end of the outer casing 50 on the second opposite direction Y2 side. The inner member 90 is, for example, a separate component from the inner housing 41 and a separate component from the outer casing 50. A portion of the inner member 90 is housed inside the outer casing 50. The inner member 90 supports the inner housing 41 inside the outer casing 50. The inner member 90 supports the inner housing 41, for example, by pressing the inner housing 41 toward the inner surface of the bottom wall 51 from inside the outer casing 50.

[0086] like Figure 9 As shown, the inner member 90 has a main body 91, a protrusion 92 protruding from the end of the main body 91 in the second opposite direction Y2 towards the second direction Y1, and one or more (four in this embodiment) engaging portions 93. The inner member 90 is, for example, a single component in which the main body 91, the protrusion 92, and the engaging portions 93 are formed as one piece. The inner member 90 is, for example, made of an insulating resin material.

[0087] The main body 91 is formed in a ring shape. The main body 91 is generally formed in a square ring shape. For example, the main body 91 has two wires 20 (see reference). Figure 5 Two through holes 91X are individually inserted. Two sealing members 100 are individually fitted inside the two through holes 91X. Each through hole 91X penetrates the main body 91 in the second direction Y1. The planar shape of each through hole 91X, for example, when viewed from the through direction of the through hole 91X, is square. The main body 91 has a partition wall 94 that separates the two through holes 91X. The partition wall 94 is provided between the two through holes 91X in the third direction Z1. The partition wall 94 extends, for example, along the entire length of the main body 91 in the second direction Y1.

[0088] The main body 91 has one or more (four in this embodiment) limiting walls 95 disposed on the inner peripheral surface of each through hole 91X. Each limiting wall 95 is formed protruding radially inward from the inner peripheral surface of the through hole 91X in the end of the second direction Y1. Each limiting wall 95 extends, for example, from the central portion of the main body 91 in the second direction Y1 to the end face of the main body 91 in the second direction Y1.

[0089] The outer peripheral surface of the main body 91 has a groove 96 for mounting the sealing member 110. The groove 96 is provided on the outer peripheral surface of the main body 91 at the end in the second direction Y1. The groove 96 is formed such that it is recessed radially inward from the outer peripheral surface of the main body 91. The groove 96 is formed continuously around the entire circumference of the main body 91. For example, the groove 96 extends from the central portion of the main body 91 in the second direction Y1 to the end face of the main body 91 in the second direction Y1.

[0090] The protrusion 92 protrudes, for example, from an end face in the partition wall 94 in the second direction Y1 toward the second direction Y1. The protrusion 92 extends, for example, in the first direction X1 and has a predetermined thickness in the third direction Z1. Figure 8 As shown, the protrusion 92 contacts the partition wall 44 of the base 42 when the inner member 90 is assembled to the outer shell 50. The top surface of the protrusion 92, that is, the end surface of the protrusion 92 in the second direction Y1, contacts the end surface of the partition wall 44 in the second opposite direction Y2. For example, by contacting the partition wall 44, the protrusion 92 presses the inner shell 41 toward the bottom wall 51, thereby supporting the inner shell 41 inside the outer shell 50.

[0091] like Figure 10 As shown, four engaging portions 93 are provided corresponding to the four engaging portions 56 of the outer casing 50. Each engaging portion 93 is formed, for example, in a manner that protrudes from the end of the main body portion 91 in the second opposite direction Y2 toward the second direction Y1. Figure 9 As shown, each engaging portion 93 is provided separately from the outer peripheral surface of the main body 91 in the first direction X1. Each engaging portion 93 is formed in a cantilever shape, with the base end connected to the main body 91 as a fixed end and the top end on the side opposite to the base end in the second direction Y1 as a free end. Each engaging portion 93 is configured to be able to flex in the first direction X1 through elastic deformation. Figure 10 As shown, each engaging portion 93 has an engaging hole 93X for engaging with the engaging portion 56. The engaging hole 93X extends, for example, along the second direction Y1. The engaging portions 93 and 56 engage with each other, for example, by a snap-fit ​​mechanism. By engaging with each other, the engaging portions 93 and 56 fix the inner member 90 to the outer casing 50.

[0092] (Structure of sealing components 100 and 110)

[0093] like Figure 6 As shown, two sealing members 100 are respectively assembled to two wires 20. Each sealing member 100 is assembled to the outer peripheral surface of the insulating covering portion 24 of each wire 20. Multiple sealing members 100 are individually fitted into the inner side of multiple through holes 91X. Each sealing member 100 is formed as an annular shape having an outer peripheral surface along the inner peripheral surface of the through hole 91X. Each sealing member 100 has a through hole 101 through which each wire 20 passes. The inner peripheral surface of the through hole 101 is formed to follow the shape of the outer peripheral surface of the wire 20. Each sealing member 100 is configured to be elastically deformable. Each sealing member 100 is in close contact with the outer peripheral surface of the wire 20 and the inner peripheral surface of the through hole 91X. Each sealing member 100 seals the space between the outer peripheral surface of the wire 20 and the inner peripheral surface of the inner member 90. Furthermore, the end face of each sealing member 100 in the second direction Y1 is... Figure 9The limiting wall 95 is shown in contact with the sealing member 100. By contacting the limiting wall 95, the insertion depth of each sealing member 100 relative to each through hole 91X is limited. In other words, the limiting wall 95 functions to position each sealing member 100 within each through hole 91X.

[0094] like Figure 6 As shown, the sealing member 110 is fitted onto the outer peripheral surface of the inner member 90. The sealing member 110 is, for example, fitted onto the bottom surface of the groove 96 of the main body 91. The sealing member 110 is disposed inside the outer casing 50. The sealing member 110 is formed as a continuous ring extending throughout the entire circumference of the inner member 90. The outer peripheral surface of the sealing member 110 is shaped to follow the inner peripheral surface of the outer casing 50. The inner peripheral surface of the sealing member 110 is shaped to follow the outer peripheral surface of the inner member 90. The sealing member 110 is configured to be elastically deformable. The sealing member 110, for example, is in close contact with the outer peripheral surface of the inner member 90 and with the inner peripheral surface of the outer casing 50. The sealing member 110 seals the space between the outer peripheral surface of the inner member 90 and the inner peripheral surface of the outer casing 50.

[0095] Sealing components 100 and 110 are, for example, made of rubber. Materials used for sealing components 100 and 110 include, for example, nitrile rubber, silicone rubber, polyurethane rubber, acrylic rubber, butyl rubber, ethylene propylene rubber, etc.

[0096] (Structure of stop body 120)

[0097] like Figure 5 As shown, the stop 120 is fitted to the end of the housing 50 on the second opposite direction Y2 side. The stop 120 prevents the inner member 90 and the sealing member 100 from detaching from the connector housing 40. The stop 120 is, for example, made of an insulating resin material. The stop 120 is, for example, a separate component from the inner housing 41, the housing 50, and the inner member 90. The stop 120 is, for example, provided to cover a portion of the outer periphery of the housing 50. The stop 120, for example, contacts the end face of the inner member 90 on the second opposite direction Y2. The stop 120, for example, contacts the end face of the sealing member 100 on the second opposite direction Y2. Furthermore, the inner member 90 is sandwiched between the housing 50 and the stop 120 in the second direction Y1.

[0098] like Figure 8 As shown, the stop 120 has a main body 121 and a cover 130 protruding from the main body 121 in a second direction Y1. The main body 121 has two wire through holes 122 through which two wires 20 pass. Each wire through hole 122 passes through the main body 121 in the second direction Y1. The cover 130 covers, for example, the outer peripheral surface of the outer casing 50. Figure 10As shown, the cover portion 130 has a locking portion 131 that engages with the locking portion 57 of the outer shell 50, and a locking portion 132 that engages with the locking portion 58 of the outer shell 50.

[0099] like Figure 11 and Figure 12 As shown, the stop body 120 is composed of multiple (two in this embodiment) segments 141 and 142. The stop body 120 is formed by combining two segments 141 and 142. The two segments 141 and 142 have, for example, the same shape.

[0100] (Structure of segments 141 and 142)

[0101] The partition 141 has a partition body portion 121A and a partition cover portion 130A. Similarly, the partition 142 has a partition body portion 121A and a partition cover portion 130A. Each partition 141, 142 is, for example, a single component in which the partition body portion 121A and the partition cover portion 130A are formed integrally. In the stop body 120, the partition body portion 121A of the partition 141 and the partition body portion 121A of the partition 142 are combined to form the body portion 121. In the stop body 120, the partition cover portion 130A of the partition 141 and the partition cover portion 130A of the partition 142 are combined to form the cover portion 130. The structure of the partition 141 of the two partitions 141, 142 will be described in detail below, while a detailed description of the structure of the partition 142 will be omitted.

[0102] (Structure of segment 141)

[0103] The dividing main body 121A has multiple dividing through holes 122A constituting wire through holes 122A, engaging parts 123, engaging parts 124, and engaging parts 125. The dividing main body 121A has a facing surface 126 opposite to the other dividing body 142. The facing surface 126 of the dividing body 142 is the surface of the dividing main body 121A in the first opposite direction X2.

[0104] Each segmented through-hole 122A is formed by being recessed from the opposing surface 126 toward the first direction X1, that is, away from the other segment 142. The inner surface of each segmented through-hole 122A is formed as a curved surface bent into an arc shape. The shape of the inner surface of each segmented through-hole 122A, for example, when viewed from the second direction Y1, is formed as a semi-circle. When a pair of segments 141 and 142 are combined, the segmented through-holes 122A of segment 141 and segmented through-holes 122A of segment 142 constitute wire through-holes 122. A plurality of segmented through-holes 122A are provided at intervals in the third direction Z1.

[0105] Each segmented through-hole 122A has one or more (three in this embodiment) protrusions 127 on its inner surface, protruding radially inward from the inner surface of the segmented through-hole 122A toward the wire through-hole 122. The protrusions 127 are spaced apart, for example, circumferentially around the wire through-hole 122. Each protrusion 127 will guide the wire 20 (refer to...) through the wire through-hole 122. Figure 10 Press the protrusion 127 radially inward toward the wire through hole 122. Each protrusion 127 can be formed into any shape. In this embodiment, each protrusion 127 is formed into a hemispherical shape.

[0106] like Figure 11 As shown, the engaging portion 123 is provided on the outer surface of the dividing main body portion 121A. The engaging portion 123 is, for example, provided on one end face of the dividing main body portion 121A in the width direction. Here, the width direction of the dividing main body portion 121A extends along the third direction Z1. In this embodiment, the engaging portion 123 is provided on the end face of the dividing main body portion 121A in the third direction Z1. The engaging portion 123 is formed protruding from the surface of the dividing main body portion 121A in the third direction Z1 toward the third direction Z1.

[0107] A locking portion 124 is provided on the outer surface of the dividing main body portion 121A. For example, the locking portion 124 is provided at the end of the dividing main body portion 121A in the width direction, on the side opposite to the locking portion 123. In this embodiment, the locking portion 124 is provided at the end of the dividing main body portion 121A in the third opposite direction Z2. Figure 12 As shown, the engaging portion 124 is formed, for example, protruding from the middle portion of the dividing main body portion 121A in the first direction X1 toward the first opposite direction X2. The top end of the engaging portion 124 protrudes toward the opposing surface 126 in the first opposite direction X2. The engaging portion 124 is formed in a cantilever shape, with the base end as the fixed end and the top end as the free end. The engaging portion 124 is configured to be able to flex in the third direction Z1 by elastic deformation. Each engaging portion 124 has an engaging hole 124X that engages with the engaging portion 123 of the other dividing body 142. The engaging hole 124X extends along the first direction X1. The engaging portion 124 of the dividing body 141 and the engaging portion 123 of the dividing body 142 engage with each other, for example, by a snap-fit ​​mechanism. Similarly, as Figure 11 As shown, the engaging portion 123 of the dividing body 141 and the engaging portion 124 of the dividing body 142 engage with each other, for example, by a snap-fit ​​mechanism.

[0108] like Figure 13As shown, the engaging portion 125 is disposed inside the stop body 120. When the pair of partitions 141 and 142 are combined to form the stop body 120, the engaging portion 125 is disposed inside the stop body 120, that is, in a position not exposed to the outside of the stop body 120. The engaging portion 125 is disposed between the two wire through holes 122 in the direction in which the two wire through holes 122 are arranged, specifically in the third direction Z1. Therefore, one of the two wire through holes 122 (the first wire through hole) is disposed between the engaging portion 123 and the engaging portion 125 of one partition 141 in the third direction Z1. Furthermore, the other wire through hole 122 (the second wire through hole) is disposed between the engaging portion 124 and the engaging portion 125 of one partition 141 in the third direction Z1.

[0109] The dividing main body 121A has a recess 128 provided on the opposing surface 126, and an elastic sheet 129 that can elastically deform and protrude from the bottom surface of the recess 128 toward the other dividing body 142. Furthermore, an engaging portion 125 is provided at the top end of the elastic sheet 129.

[0110] The recess 128 is formed such that it is recessed in the first direction X1 from the opposing surface 126 between the two dividing through holes 122A, which is located in the width direction of the dividing main body portion 121A. An elastic piece 129 protrudes from the bottom surface of the recess 128 in the first opposite direction X2. The elastic piece 129 is formed in a cantilever shape, with a base end connected to the bottom surface of the recess 128 as a fixed end and a top end on the side opposite to the base end in the first direction X1 as a free end. The elastic piece 129 is configured to be able to flex in the third direction Z1 through elastic deformation. The elastic piece 129 is provided separately from the inner peripheral surface of the recess 128.

[0111] like Figure 14 As shown, the elastic sheet 129 is disposed separately from the inner circumference of the recess 128, covering the entire circumference of the recess 128. In other words, the inner circumference of the recess 128 surrounds the outer circumference of the elastic sheet 129 in a state separated from it. Figure 13 As shown, the top end of the elastic sheet 129 protrudes toward the opposite dividing body 142 of the opposing surface 126.

[0112] The engaging portion 125 is provided, for example, at the top end of the elastic piece 129 in the portion protruding in the first opposite direction X2 relative to the opposing surface 126. The engaging portion 125 is formed, for example, a protrusion extending from the end face of the elastic piece 129 in the third opposite direction Z2 toward the third opposite direction Z2. The engaging portion 125 is configured to engage with the engaging portion 125 of the other segment 142. When the pair of segments 141 and 142 are assembled, the engaging portions 125 of the pair of segments 141 and 142 engage with each other. The engaging portions 125 of segment 141 and segment 142 engage with each other, for example, by a snap-fit ​​mechanism. In the assembled state of the pair of segments 141 and 142, for example, the end face of the engaging portion 125 of segment 141 in the first direction X1 engages with the end face of the engaging portion 125 of segment 142 in the first opposite direction X2. At this time, the top end of the elastic piece 129 of the dividing body 141 and the engaging portion 125 are housed in the recess 128 of the other dividing body 142. Similarly, the top end of the elastic piece 129 of the dividing body 142 and the engaging portion 125 are housed in the recess 128 of the other dividing body 141. Thus, the pair of engaging portions 125 engage with each other inside the stop body 120.

[0113] like Figure 12 As shown, the dividing cover portion 130A protrudes from the end face of the dividing main body portion 121A in the second direction Y1 toward the second direction Y1. The dividing cover portion 130A has, for example, an engaging portion 131, an engaging portion 132, and a notch portion 133.

[0114] The engaging part 131 and the engaging part 57 of the outer casing 50 (see reference) Figure 10 Correspondingly, the engaging portion 131 is formed as a flat plate extending along the second direction Y1. The engaging portion 131 is formed as a cantilever, with the base end connected to the dividing main body portion 121A as a fixed end and the top end on the side opposite to the base end in the second direction Y1 as a free end. The engaging portion 131 is configured to be able to flex in the first direction X1 through elastic deformation. Figure 4 As shown, the engaging portion 131 has an engaging hole 131X for engaging with the engaging portion 57. The engaging portion 131 and the engaging portion 57 engage with each other, for example, by a snap-fit ​​mechanism. The engaging portion 131 is located at a different position in the circumferential direction of the outer casing 50 than the engaging portion 93 of the inner member 90. Therefore, the engaging portion 131 and the engaging portion 93 are arranged so that they do not overlap in the radial direction of the outer casing 50.

[0115] The engaging portion 132 is provided correspondingly to the engaging portion 58 of the outer casing 50. For example... Figure 12As shown, the engaging portion 132 is provided, for example, at the end of the segmented cover portion 130A in the third opposite direction Z2. The engaging portion 132 is arranged, for example, with the engaging portion 124 along the second direction Y1. The engaging portion 132 is formed such that it protrudes from the end of the segmented cover portion 130A in the first direction X1 toward the first opposite direction X2. The top end of the engaging portion 132 protrudes toward the opposing surface 126 in the first opposite direction X2. The engaging portion 132 is formed in a cantilever shape, with the base end as a fixed end and the top end as a free end. The engaging portion 132 is configured to be able to flex in the third direction Z1 through elastic deformation. Figure 10 As shown, the engaging portion 132 has an engaging hole 132X for engaging with the engaging portion 58. The engaging hole 132X extends along the first direction X1. The engaging portion 132 and the engaging portion 58 engage with each other, for example, by a snap-fit ​​mechanism.

[0116] like Figure 12 As shown, the notch 133 is formed such that it is recessed from the top end of the dividing cover portion 130A on the second direction Y1 side toward the dividing main body portion 121A. In this embodiment, the notch 133 is formed such that it is recessed from the top end of the dividing cover portion 130A on the second direction Y1 side to the end face of the dividing main body portion 121A on the second direction Y1 side. Figure 4 As shown, the notch 133 is provided corresponding to the engaging portion 93 of the inner member 90. The notch 133 is provided at a position where it overlaps with the engaging portion 93 in the circumferential direction of the outer shell 50. The notch 133 is formed in such a way that the engaging portion 93 is exposed. In this embodiment, the notch 133 is provided on both sides of the engaging portion 131 in the third direction Z1. By providing the notch 133, the engaging portion 93 can be provided within the notch 133, thus enabling the connector 30 to be miniaturized compared to a structure without the notch 133.

[0117] Next, an example of the assembly method of connector 30 will be described.

[0118] First, a sealing member 100 is individually installed on each of the multiple wires 20. Next, the wires 20 with the sealing member 100 installed are inserted into the through holes 91X of the inner member 90. Thus, the sealing member 100 individually engages with the inner sides of the multiple through holes 91X. Next, the sealing member 110 (refer to...) Figure 5 With the inner member 90 installed on its outer peripheral surface, the inner member 90 is inserted into the interior of the outer casing 50. Furthermore, by engaging the engaging portion 93 of the inner member 90 with the engaging portion 56 of the outer casing 50, the inner member 90 is assembled at the end of the outer casing 50. At this time, as... Figure 5As shown, the outer peripheral surface of the wire 20 is sealed to the inner peripheral surface of the inner member 90 by the sealing member 100, and the outer peripheral surface of the inner member 90 is sealed to the inner peripheral surface of the outer casing 50 by the sealing member 110. This prevents liquids such as water from seeping into the interior of the outer casing 50 from the end of the casing 50. Furthermore, the sealing member 100 can be installed individually for multiple wires 20, thus improving the workability of installing the sealing member 100 on the wires 20 compared to installing multiple wires 20 together with a rubber plug.

[0119] Next, as Figure 10 As shown, a stop 120 is fitted to the end of the housing 50. For example, a pair of split bodies 141 and 142 are fitted to the housing 50 from the first direction X1 and the first opposite direction X2. That is, the pair of split bodies 141 and 142 are fitted to the housing 50 from a direction intersecting the insertion direction of the wire 20 relative to the connector housing 40 (here, the second direction Y1). The pair of split bodies 141 and 142 are fitted to the housing 50 in such a way that the engaging part 131 engages with the engaging part 57 and the engaging part 132 engages with the engaging part 58. In addition, while the pair of split bodies 141 and 142 are being fitted to the housing 50, as Figure 13 As shown, a pair of separate bodies 141 and 142 are assembled. When the pair of separate bodies 141 and 142 are assembled, the engaging portion 123 of separate body 141 engages with the engaging portion 124 of separate body 142, the engaging portion 124 of separate body 141 engages with the engaging portion 123 of separate body 142, and the engaging portions 125 of separate bodies 141 and 142 engage with each other. By engaging in these three places, the pair of separate bodies 141 and 142 can be securely engaged. Furthermore, as... Figure 5 As shown, when a pair of split bodies 141 and 142 are assembled into the outer casing 50, the end face of the split body portion 121A of each split body 141 and 142 in the second direction Y1 contacts the inner member 90 and the sealing member 100. This prevents the inner member 90 and the sealing member 100 from detaching from the connector housing 40.

[0120] Next, the effects of this implementation method will be explained.

[0121] (1) An inner member 90, having multiple through holes 91X through which multiple wires 20 pass individually, is assembled to the end of a connector housing 40, and a sealing member 100 is individually fitted into each of the multiple through holes 91X. Therefore, for example, by individually installing the sealing member 100 on each wire 20 and inserting the wire 20 with the sealing member 100 installed into the through hole 91X of the inner member 90, the wire 20 and the sealing member 100 can be assembled into the inner member 90. Therefore, since the sealing member 100 can be individually installed on each wire 20, the workability of installing the sealing member 100 on the wires 20 is improved compared to the case of installing multiple wires 20 on a total rubber plug. This improves the assembly workability of the connector 30.

[0122] However, in existing connectors, when only sealing members are installed for each wire, gaps are created between adjacent sealing members in the direction of multiple wire arrangement, thus failing to seal the connector housing and the wires. In contrast, the connector 30 of this embodiment includes: an inner member 90 having multiple through holes 91X; multiple sealing members 100 individually fitted with the multiple through holes 91X; and a sealing member 110 fitted with the outer side of the inner member 90. Here, each sealing member 100 is in close contact with the inner peripheral surface of the through hole 91X and the outer peripheral surface of the wire 20. Furthermore, the sealing member 110 is in close contact with the outer peripheral surface of the inner member 90 and the inner peripheral surface of the connector housing 40. Through these inner members 90, sealing members 100, and sealing members 110, the outer peripheral surface of the wire 20 is sealed with the inner peripheral surface of the inner member 90, and the outer peripheral surface of the inner member 90 is sealed with the inner peripheral surface of the connector housing 40. This prevents liquids such as water from seeping into the interior of the connector housing 40 from the ends. By configuring the inner component 90 with multiple through holes 91X in this way, the assembly workability of the connector 30 can be improved, and the waterproofness of the connector 30 can be maintained.

[0123] (2) A stop body 120 is provided to prevent the inner component 90 and the sealing component 100 from detaching from the connector housing 40. Therefore, it is possible to prevent the inner component 90 and the sealing component 100 from detaching from the connector housing 40. As a result, the waterproofness of the connector 30 can be properly maintained.

[0124] (3) The engaging portion 93 of the inner member 90 and the engaging portion 131 of the stop body 120 are provided at different positions in the circumferential direction of the connector housing 40. Therefore, the engaging portion 93 and the engaging portion 131 are provided at non-overlapping positions in the radial direction of the connector housing 40. Therefore, compared with the case where the engaging portion 93 and the engaging portion 131 overlap in the radial direction of the connector housing 40, the connector 30 can be miniaturized in the radial direction of the connector housing 40.

[0125] (4) A stop 120 is formed by a pair of split bodies 141 and 142. Therefore, for example, after the wire 20 is inserted into the connector housing 40, the stop 120 can be fitted to the end of the connector housing 40. As a result, the workability of fitting the stop 120 into the connector housing 40 can be improved, and the assembly workability of the connector 30 can be improved.

[0126] (5) The pair of split bodies 141 and 142 are engaged at three points: engaging portion 123, engaging portion 124, and engaging portion 125. Therefore, the pair of split bodies 141 and 142 can be securely engaged with each other. This appropriately suppresses the separation of the pair of split bodies 141 and 142, and thus appropriately suppresses the stop body 120 from falling off the connector housing 40. Furthermore, because the engaging portion 125 is located inside the stop body 120, it prevents operators from accidentally disengaging the engaging portion 125. Therefore, the separation of the pair of split bodies 141 and 142 can be appropriately suppressed, and the stop body 120 can be appropriately suppressed from falling off the connector housing 40.

[0127] (6) An engaging portion 125 is provided at the top end of the elastic piece 129 that protrudes from the bottom surface of the recess 128 provided on the opposing surface 126 toward the other dividing body 142. Therefore, compared with a structure that does not have a recess 128, that is, a structure in which the elastic piece 129 is provided on the opposing surface 126, the space in which the elastic piece 129 can be flexed can be formed to be wider, and the enlargement of the stop body 120 can be suppressed.

[0128] (7) A protrusion 127 is provided on the inner peripheral surface of each wire through hole 122, protruding from the inner peripheral surface of the wire through hole 122 toward the radially inward side of the wire through hole 122, that is, the wire 20 passing through the wire through hole 122. This protrusion 127 can adequately support the wire 20 passing through the wire through hole 122, thus appropriately suppressing the wobbling of the wire 20 inside the wire through hole 122. Therefore, for example, relative movement of the terminal 31 connected to the end of the wire 20 relative to the terminal 201, which is the opposite terminal, can be appropriately suppressed. As a result, contact wear of the terminal 31 and the terminal 201 can be appropriately suppressed.

[0129] (8) One of the two wire through holes 122 (the first wire through hole) is disposed in the third direction Z1 between the engaging portion 123 and the engaging portion 125 of the dividing body 141. The other wire through hole 122 (the second wire through hole) is disposed in the third direction Z1 between the engaging portion 124 and the engaging portion 125 of the dividing body 141. That is, each of the two wire through holes 122 is disposed such that it is sandwiched between two engaging portions of the pair of dividing bodies 141 and 142. Therefore, compared to, for example, the case where only one engaging portion is disposed near each wire through hole 122, the engagement of the pair of dividing bodies 141 and 142 in each wire through hole 122 can be made more secure. Therefore, the pair of segments 141, 142 can be appropriately brought close to each other in each wire through hole 122, and the protrusion 127 provided on the inner peripheral surface of each wire through hole 122 can stably support the wire 20. Therefore, the shaking of the wire 20 inside each wire through hole 122 can be appropriately suppressed.

[0130] (9) Since the pair of segments 141 and 142 are formed with the same shape, the increase in the number of parts, specifically the number of part types, can be suppressed. In addition, the molds used to manufacture the segments 141 and 142 can be shared, thereby reducing the number of molds and improving the manufacturability of the stop body 120. This, in turn, improves the manufacturability of the connector 30.

[0131] (10) The inner housing 41 that houses the terminal 31 is supported by the inner member 90 inside the outer housing 50. Therefore, when vibration is applied to the connector 30, the shaking of the inner housing 41 inside the outer housing 50 can be suppressed. As a result, relative movement of the terminal 31 housed in the inner housing 41 relative to the terminal 201, which is the counterpart terminal, can be suppressed, and contact wear of the terminal 31 and the terminal 201 can be appropriately suppressed.

[0132] (11) Multiple terminal storage sections 43 are formed as a single unit via the base 42. Therefore, compared to the case where the multiple terminal storage sections 43 are composed of separate parts, the number of parts can be reduced. In addition, the inner member 90 can support the multiple terminal storage sections 43 by contacting the base 42. Therefore, compared to the case where a structure for supporting the multiple terminal storage sections 43 is provided separately, the structure of the inner member 90 can be simplified.
