[0024] In the present application, the term "connection" is not limited to mechanical connection, but can include electrical connection. That is, the term "connection" is not limited to the case where two elements as connection objects are directly connected, but can include the case where two elements as connection objects are connected with other elements interposed therebetween. The term "limit" is not limited to the case where one of the two members is always in contact with the other member to limit movement of the one member relative to the other member. The term "limit" can include, for example, the case where the two members are not in contact with each other in a state where positional displacement does not occur, but the two members are in contact with each other when one of the two members is to be displaced relative to the other member, thereby limiting movement of the one member relative to the other member. In addition, the term "limit" means limiting movement in at least one direction.

[0025] Hereinafter, the right-hand system XYZ coordinate system shown in each drawing is defined. The X direction, the Y direction, and the Z direction are defined as follows. The X direction is the fitting direction of the connector 1 and the partner connector. The +X direction is the direction from the connector 1 toward the partner connector. The Y direction is the direction intersecting (orthogonal to, in the present embodiment) the X direction, and is the direction in which the terminals 40 described later are arranged. The Z direction is the direction intersecting (orthogonal to, in the present embodiment) the X direction and the Y direction. In addition, hereinafter, for convenience of explanation, the +X direction is sometimes referred to as "front side", and the -X direction is sometimes referred to as "rear side".

[0026] (EMBODIMENT) ​​​

[0027] The connector 1 of the embodiment is a connection member for electrically connecting the electric wire 41 with a terminal member provided in a counterpart connector (not shown). For example, the connector 1 is a connector 1 for a vehicle such as an EV (Electric Vehicle), an HEV (Hybrid Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle). The connector 1 is, for example, a high-voltage connector through which a current of 100 V or more flows. However, the connector 1 can also be a low-voltage connector. In the embodiment, the connector 1 is a connector 1 corresponding to three electrodes. However, the connector 1 can be a connector 1 corresponding to two or fewer electrodes, or a connector 1 corresponding to four or more electrodes.

[0028] Figure 1 is a perspective view showing the connector 1 of the embodiment. Figure 2 is an exploded perspective view showing the connector 1 of the embodiment. Figure 3 is a plan view showing the connector 1 of the embodiment.

[0029] As shown in Figures 1 to 3 , the connector 1 includes a housing 10, a terminal 40, a housing 50, and a rear holder 60. The rear holder 60 is an example of a "holder".

[0030] The housing 10 is a member that is combined with a counterpart connector. For example, the housing 10 is made of synthetic resin. The housing 10 has insulating properties. The housing 10 includes a front portion 11 that supports the terminal 40 and an electric wire accommodation portion 21 through which the electric wire 41 connected to the terminal 40 passes. The front portion 11 is an example of a "terminal support portion".

[0031] The front portion 11 is a portion of the housing 10 that is combined with a counterpart connector. The front portion 11 includes a terminal accommodation portion 13 that accommodates the terminal 40 and a cover portion 12 that covers the terminal accommodation portion 13. Note that the shape of the front portion 11 described below is an example, and the shape of the front portion is not particularly limited.

[0032] Figure 4 is a cross-sectional view showing the connector 1 of the embodiment, showing a cross section at a position along the IV-IV line of Figure 9

[0033] As shown in Figure 2 and Figure 4 ​As shown, the cover portion 12 is formed into a bottomed cylindrical shape having a peripheral wall portion and a bottom wall portion, and is opened in the +X direction for connection with a counterpart connector. The cover portion 12 is a cylindrical shape of an oblong circle having a long axis in the Y direction. Further, in the present embodiment, the oblong circle can be replaced with an ellipse. An annular seal member can be mounted to the outer periphery of the cover portion 12.

[0034] The terminal housing portion 13 supports the terminal 40 in a manner incapable of relative displacement. The terminal housing portion 13 is provided in the same number as the terminal 40, and holds one terminal 40 respectively. The terminal housing portions 13 are arranged in the Y direction inside the cover portion 12. The terminal housing portion 13 is a cylindrical shape extending in the X direction. The terminal housing portion 13 is a square cylindrical shape. The terminal housing portion 13 penetrates the bottom wall of the cover portion 12. The terminal 40 is disposed inside the terminal housing portion 13. The inside of the terminal housing portion 13 is opened in the +X direction for connection of the terminal 40 with a terminal 40 of a counterpart connector. In addition, the inside of the terminal housing portion 13 is opened in the -X direction for leading out of the electric wire 41 to the rear from the front portion 11. The terminal 40 is inserted into the inside of the terminal housing portion 13 in the +X direction through the electric wire housing portion 21 in a state connected with the electric wire 41. The terminal 40 is stopped by the spacer 14 in the terminal housing portion 13. The spacer 14 is disposed so as to fill a gap in the Y direction between the side wall of the Y direction of the terminal housing portion 13 and the terminal 40.

[0035] Figure 5 is a perspective view showing the housing 10 of the embodiment.

[0036] As shown in Figure 4 and Figure 5 , the electric wire housing portion 21 protrudes in the -X direction from the front portion 11. The electric wire housing portion 21 has a cylindrical portion 22, an outer side connecting portion 23, and an inner side connecting portion 24. The inner side connecting portion 24 is an example of the "contact portion".

[0037] The cylindrical portion 22 extends in the X direction. A plurality of (three in the present embodiment) cylindrical portions 22 are provided in one-to-one correspondence with the electric wires 41. The plurality of cylindrical portions 22 are arranged in the Y direction. The cylindrical portion 22 is connected to the -X direction end portion of the terminal housing portion 13. The inside of the cylindrical portion 22 communicates with the inside of the terminal housing portion 13. The electric wire 41 penetrates the inside of the cylindrical portion 22. The -X direction opening of the cylindrical portion 22 is an exit for leading out the electric wire 41 to the outside of the housing 10. When the terminal 40 is assembled to the housing 10, the terminal 40 connected with the electric wire 41 is inserted into the -X direction opening of the cylindrical portion 22.

[0038] The outer connecting portion 23 is formed as a plate extending along the XY plane. The outer connecting portion 23 connects an adjacent pair of cylindrical portions 22 to each other. The outer connecting portion 23 is configured to cover the space between the adjacent pair of cylindrical portions 22 from the outside in the Z direction. That is, there are two outer connecting portions 23 relative to an adjacent pair of cylindrical portions 22, and in this embodiment, there are four. The outer connecting portion 23 extends from the bottom wall portion of the cover portion 12 in the -X direction. The side edges of the outer connecting portion 23 in the Y direction extend along the X direction and engage with the outer peripheral surface of the cylindrical portion 22 along its entire length. The end edge of the outer connecting portion 23 in the -X direction extends along the Y direction and is located at the same position in the X direction as the end of the cylindrical portion 22 in the -X direction.

[0039] The inner connecting portion 24 connects an adjacent pair of cylindrical portions 22 to each other. The inner connecting portion 24 is disposed between an adjacent pair of outer connecting portions 23 in the Z direction. Two inner connecting portions 24 are provided relative to an adjacent pair of cylindrical portions 22; in this embodiment, four are provided. The two inner connecting portions 24 are spaced apart in the Z direction between adjacent pairs of cylindrical portions 22. The two inner connecting portions 24 have a Z-direction gap with the outer connecting portions 23. The inner connecting portion 24 extends from the bottom wall portion of the cover portion 12 in the -X direction. The side edges of the inner connecting portion 24 in the Y direction extend along the X direction and engage with the outer peripheral surface of the cylindrical portion 22 along its entire length. The end edge of the inner connecting portion 24 in the -X direction extends along the Y direction and is located at the same position in the X direction as the end of the outer connecting portion 23 in the -X direction.

[0040] like Figure 5 As shown, the wire receiving portion 21 is generally formed into a cylindrical shape with an elongated circle along its major axis in the Y direction. The wire receiving portion 21 has an outer peripheral wall portion 25 forming the outer peripheral surface of the wire receiving portion 21. The outer peripheral wall portion 25 is formed by an outer connecting portion 23 and a portion of the cylindrical portion 22.

[0041] like Figure 4 As shown, the wire 41 has a first end 41a that is directly connected to the terminal 40 inside the housing 10. At the first end 41a, the core wire of the wire 41 is fastened to the terminal 40. The core wire of the wire 41 is fastened to the terminal 40 by riveting. However, the core wire of the wire 41 can also be connected to the terminal 40 by methods other than riveting. The wire 41 extends from the first end 41a in the -X direction from the inside of the cylindrical portion 22 to the outside of the housing 10. A protective sleeve 42 is installed on the wire 41. The protective sleeve 42 is disposed inside the cylindrical portion 22. The protective sleeve 42 is in close contact with the outer circumferential surface of the wire 41 and the inner circumferential surface of the cylindrical portion 22 throughout its entire circumference.

[0042] The housing 50 is fixed to the housing 10 and is configured to be fixed to the other connector. The housing 50 is provided to cover the wire receiving portion 21. The housing 50 is inserted into the outside of the wire receiving portion 21 from the opposite side (-X direction) of the front portion 11. The +X direction is the assembly direction of the housing 50 relative to the wire receiving portion 21. The housing 50 has a surrounding portion 51 and a flange portion 52.

[0043] The surrounding portion 51 is disposed around the outer periphery of the outer peripheral wall portion 25 of the wire receiving portion 21. The shape of the surrounding portion 51 corresponds to that of the outer peripheral wall portion 25, and it is formed as an elongated cylindrical shape with a major axis along the Y direction. The inner peripheral surface of the surrounding portion 51 is close to the outer peripheral surface of the outer peripheral wall portion 25. The end edge of the surrounding portion 51 in the -X direction is located in the X direction at approximately the same position as the end edge of the outer peripheral wall portion 25 in the -X direction. Alternatively, the end edge of the surrounding portion 51 in the -X direction may be located in the X direction at a position closer to the -X direction end edge than the end edge of the wire receiving portion 21 in the -X direction. The surrounding portion 51 is disposed around the periphery of the wire receiving portion 21 and around the front portion 11.

[0044] like Figure 2 and Figure 4 As shown, the flange portion 52 extends outward from the +X direction end edge of the surrounding portion 51 in a direction orthogonal to the X direction. The flange portion 52 extends around the entire circumference of the surrounding portion 51. A threaded hole for inserting a screw is formed in the flange portion 52. The screw engages with the counterpart connector or a component surrounding the counterpart connector. That is, the flange portion 52 is fastened to the counterpart connector or a component surrounding the counterpart connector.

[0045] Figure 6 It is along Figure 3 A sectional view along line VI-VI.

[0046] like Figure 3 and Figure 6 As shown, the outer casing 50 and the housing 10 have first engaging portions 80 that engage with each other. Multiple first engaging portions 80 are provided in the Z direction and multiple in the Y direction. Each first engaging portion 80 includes a first locking hook 81 provided in the housing 10 and a first locking recess 82 provided in the outer casing 50. The first locking hook 81 is an example of a "locking hook".

[0047] like Figure 5 As shown, the first locking hook 81 is provided on the outer peripheral wall 25 of the wire receiving portion 21 of the housing 10. The first locking hook 81 is formed as a cantilever rod with the end in the +X direction as the base end (fixed end) between a pair of cuts extending from the -X direction end edge of the outer connecting portion 23. A front end face 81a facing the -X direction is formed at the front end of the first locking hook 81. The first locking hook 81 includes an arm 90, a first hook protrusion 91, a protrusion 92, and an inner rib 93.

[0048] like Figure 5 and Figure 6 As shown, the arm 90 is formed as a plate with thickness in the Z direction. The arm 90 is capable of flexing in the Z direction. The first hook protrusion 91 is the claw of the first locking hook 81. The first hook protrusion 91 is provided at the front end of the first locking hook 81. The first hook protrusion 91 protrudes outward from the outer side 90a of the arm 90 toward the surrounding portion 51. The first hook protrusion 91 protrudes outward in the Z direction from the outer peripheral wall portion 25. By flexing the arm 90 in the Z direction, the first hook protrusion 91 can elastically displace inward in a manner that separates it from the surrounding portion 51.

[0049] The protrusion 92 is separate from the first hook protrusion 91. The protrusion 92 protrudes outward from the outer side 90a of the arm 90 toward the surrounding portion 51. The protrusion 92 protrudes outward in the Z direction from the outer peripheral wall portion 25. The protrusion 92 is spaced apart in the X direction relative to the base end of the arm 90. The protrusion 92 is formed at a position closer to the base end of the first locking hook 81 than the first hook protrusion 91. The protrusion 92 is formed in a spherical notch shape (a shape with a portion of a sphere cut off). However, the shape of the protrusion 92 is not particularly limited. For example, the protrusion 92 can also be deformed by contacting the inner peripheral surface of the surrounding portion 51. An inner rib 93 is provided on the inner side 90b of the arm 90. The inner rib 93 protrudes inward from the second side 90b and extends from the front end of the arm 90 toward the base end.

[0050] like Figure 6 As shown, the inner edge of the first locking hook 81 has an inclined portion 95, which extends inward from the front end of the first locking hook 81 toward the +X direction. Furthermore, in this embodiment, the inner edge of the first locking hook 81 is a protruding end of the inner rib 93 extending along the extending direction of the inner rib 93. However, if the first locking hook 81 does not have an inner rib 93, the inner edge of the first locking hook 81 may also be the second surface 90b of the arm 90.

[0051] like Figure 3 and Figure 6 As shown, a first locking recess 82 is provided on the surrounding portion 51 of the outer casing 50. The first locking recess 82 opens on the inner peripheral surface of the surrounding portion 51. The first locking recess 82 is formed in the inner peripheral surface of the surrounding portion 51 at a position opposite to the first hook protrusion 91. In this embodiment, the first locking recess 82 penetrates through the surrounding portion 51 in the thickness direction and opens at the end edge of the surrounding portion 51 in the -X direction.

[0052] like Figure 6As shown, in the fully engaged state of the housing 10 and the outer shell 50, the first hook protrusion 91 enters the first locking recess 82. The opening edge of the first locking recess 82 engages with the first hook protrusion 91 from the +X direction, thereby restricting the movement of the outer shell 50 relative to the housing 10 in the -X direction. With the first hook protrusion 91 engaged in the first locking recess 82, the protrusion 92 abuts against the inner circumferential surface of the surrounding portion 51 from the inside. On the other hand, in the partially engaged state of the housing 10 and the outer shell 50, the first hook protrusion 91 slides in contact with the portion surrounding the first locking recess 82 in the inner circumferential surface of the surrounding portion 51, and does not engage with the first locking recess 82. With the first hook protrusion 91 in sliding contact with the inner circumferential surface of the surrounding portion 51, the protrusion 92 separates from the inner circumferential surface of the surrounding portion 51 inward.

[0053] Figure 7 This is a perspective view showing the rear retainer 60 of the embodiment.

[0054] like Figure 4 and Figure 7 As shown, the rear retainer 60 holds a flexible wire 41. The rear retainer 60 is disposed in the housing 10 and the outer casing 50 in a manner that prevents relative displacement. The rear retainer 60 is assembled relative to the housing 10 in the +X direction. The rear retainer 60 is embedded inside the wire receiving portion 21 and directly fixed to the housing 10. The rear retainer 60 has a closing portion 61 and an insertion portion 62.

[0055] Figure 8 It is along Figure 3 A cross-sectional view of line VIII-VIII.

[0056] like Figure 4 and Figure 8 As shown, the blocking portion 61 is formed integrally to cover the end of the wire receiving portion 21 in the -X direction and the end of the surrounding portion 51 of the housing 50 in the -X direction. The shape of the blocking portion 61 corresponds to the shape of the opening edge (end edge in the -X direction) of the surrounding portion 51 in the -X direction, and when viewed from the X direction, it is formed as a plate with an elongated oval shape along the major axis in the Y direction (see reference). Figure 7 The outer periphery of the blocking portion 61 is opposite to the opening edge of the surrounding portion 51 in the -X direction (see reference). Figure 3 The outer periphery of the blocking portion 61 is substantially adjacent to the opening edge of the surrounding portion 51 in the -X direction without gap. However, the outer periphery of the blocking portion 61 may also approach with a slight gap relative to the opening edge of the surrounding portion 51 in the -X direction. By ensuring that the blocking portion 61 is substantially adjacent to the opening edge of the surrounding portion 51 in the -X direction without gap, it is possible to identify from the outside that the rear retainer 60 is positioned correctly relative to the outer casing 50 and the housing 10.

[0057] like Figure 4 and Figure 7As shown, the insertion part 62 is inserted into the inner side of the cylindrical part 22 of the wire receiving part 21 from the opposite side of the front part 11. The number of insertion parts 62 is the same as that of the cylindrical parts 22, with one inserted into the inner side of each cylindrical part 22. The insertion part 62 corresponds to the internal shape of the cylindrical part 22 and is formed into a cylindrical shape extending in the X direction.

[0058] Figure 9 It is along Figure 3 A cross-sectional view of the IX-IX line.

[0059] like Figure 9 As shown, a protrusion 63 is formed on the inner peripheral surface of the insertion portion 62. The wire 41 passes through the inner side of the insertion portion 62. The protrusion 63 of the insertion portion 62 is embedded in the coating of the wire 41, thereby holding the wire 41 in a non-displaceable manner.

[0060] like Figure 6 and Figure 7 As shown, the rear retainer 60 includes a limiting portion 64, which is inserted into the inner side of the outer peripheral wall portion 25 of the wire receiving portion 21 from the side opposite to the front portion 11. The limiting portion 64 is disposed inside the first locking hook 81. The limiting portion 64 protrudes in the +X direction from the blocking portion 61 toward the interior of the outer peripheral wall portion 25. The limiting portion 64 is provided in a one-to-one correspondence with the first hook protrusion 91. The limiting portion 64 is inserted between the first locking hook 81 and the inner connecting portion 24. The limiting portion 64 is in direct contact with the first locking hook 81, limiting the displacement of the first locking hook 81 in the direction away from the surrounding portion 51 (inner side). The limiting portion 64 is in direct contact with the inner connecting portion 24, limiting the displacement to the side away from the first locking hook 81 (inner side). That is, the inner connecting portion 24 contacts the limiting portion 64 from the side opposite to the first locking hook 81 relative to the limiting portion 64.

[0061] The limiting portion 64 has a pressing rib 70 that presses the first locking hook 81 against the inner peripheral surface of the surrounding portion 51. The pressing rib 70 protrudes outward from the main body of the limiting portion 64 toward the first locking hook 81 and extends in the -X direction from the front end of the limiting portion 64. The pressing rib 70 protrudes outward in the Z direction. The thickness of the pressing rib 70 in the Y direction is smaller than the width of the first locking hook 81 in the Y direction. The pressing rib 70 is flattened and presses against the first locking hook 81 during the insertion of the limiting portion 64 between the first locking hook 81 and the inner connecting portion 24. The pressing rib 70 contacts the protrusion back side region 96 of the first locking hook 81 located on the back side of the protrusion 92. Furthermore, the protrusion back side region 96 is the area of ​​the first locking hook 81 that, when viewed from the thickness direction of the arm 90, coincides with the formation range of the protrusion 92. The compression rib 70 presses the first locking hook 81 in such a way that the first hook protrusion 91 enters the first locking recess 82 and the first locking hook 81 is pressed against the inner peripheral surface of the surrounding portion 51. In this embodiment, the state in which the first locking hook 81 is pressed against the inner peripheral surface of the surrounding portion 51 is such that the protrusion 92 abuts against the inner peripheral surface of the surrounding portion 51.

[0062] The front end of the limiting part 64 tapers in such a way that its thickness in the Z direction decreases as it moves toward the +X direction. The front end of the limiting part 64 has a sliding surface 65 that extends toward the side of the surrounding part 51 (outer side in the Z direction) when viewed from the X direction, as it moves toward the -X direction. During the insertion of the insertion part 62 into the inner side of the cylindrical part 22, the inclined portion 95 at the front end of the first locking hook 81 slides on the sliding surface 65, flattening the compression rib 70 and pressing it toward the side of the surrounding part 51 (outer side in the Z direction).

[0063] Furthermore, in the semi-fitted state of the housing 10 and the outer casing 50, the front end of the first locking hook 81 is located further inward than in its normal position. During the insertion of the insertion part 62 into the cylindrical part 22, the front end of the limiting part 64 abuts against the front end face 81a of the first locking hook 81. By the abutting of the front end of the limiting part 64 against the front end face 81a of the first locking hook 81, the insertion of the insertion part 62 into the cylindrical part 22 is restricted. In the semi-fitted state of the housing 10 and the outer casing 50, with the rear retainer 60 located in a position further in the -X direction than in its normal position relative to the outer casing 50 and the housing 10, the insertion of the insertion part 62 into the cylindrical part 22 is also restricted.

[0064] like Figure 5 , Figure 7 and Figure 8 As shown, the housing 10 and the rear retainer 60 have second engaging portions 85 that engage with each other. Multiple second engaging portions 85 are provided in the Z direction and multiple in the Y direction. Each second engaging portion 85 includes a second locking hook 86 provided on the rear retainer 60 and a second locking recess 87 provided on the housing 10.

[0065] like Figure 7 and Figure 8 As shown, a second locking hook 86 is provided in each insertion portion 62. The second locking hook 86 is provided at the +Z direction end and the -Z direction end of each insertion portion 62. The second locking hook 86 is cantilevered with the +X direction end as the base end (fixed end). The second locking hook 86 is connected to the opening edge of the recess formed on the outer peripheral surface of the insertion portion 62. The second locking hook 86 is formed as a plate with thickness in the Z direction. The second locking hook 86 is flexible in the Z direction. The second locking hook 86 has a second hook protrusion 88. When viewed from the X direction, the second hook protrusion 88 protrudes outward from the outer peripheral surface of the insertion portion 62 toward the cylindrical portion 22. The second hook protrusion 88 protrudes outward from the outer peripheral surface of the insertion portion 62 in the Z direction. By flexing the second locking hook 86 in the Z direction, the second hook protrusion 88 can elastically displace inward in a manner that separates from the cylindrical portion 22.

[0066] like Figure 5 and Figure 8 As shown, a second locking recess 87 is provided on the outer peripheral wall 25 of the wire receiving portion 21 of the housing 10. The second locking recess 87 opens on the inner peripheral surface of each cylindrical portion 22. The second locking recess 87 is formed in the inner peripheral surface of the cylindrical portion 22 at a position opposite to the second hook protrusion 88. In this embodiment, the second locking recess 87 penetrates the cylindrical portion 22 radially. In the fully engaged state of the housing 10 and the rear retainer 60, the second hook protrusion 88 enters the second locking recess 87. The opening edge of the second locking recess 87 engages with the second hook protrusion 88 in the -X direction, thereby restricting the movement of the rear retainer 60 relative to the housing 10 in the -X direction.

[0067] like Figure 2 and Figure 9 As shown, the rear retainer 60 is formed by combining two components in such a way that the wires 41 are clamped from both sides in the Z direction. In other words, the rear retainer 60 is formed to be divisible into two parts. The two components forming the rear retainer 60 are formed in such a way that all the wires 41 arranged along the Y direction are clamped together from both sides in the Z direction. The rear retainer 60 retains the wires 41 by using the two components to clamp the wires 41.

[0068] In this embodiment, the housing 10 has a first locking hook 81 extending along the inner circumferential surface of the surrounding portion 51 of the outer casing 50 and engaging with the surrounding portion 51. The rear retainer 60 has a pressing rib 70 disposed inside the wire receiving portion 21 and pressing the first locking hook 81 against the inner circumferential surface of the surrounding portion 51. With this configuration, since the first locking hook 81 is reliably clamped between the surrounding portion 51 and the pressing rib 70, loosening between the housing 10 and the outer casing 50, and between the housing 10 and the rear retainer 60, can be prevented. Therefore, the wire 41 held in the rear retainer 60 is fixed relative to the outer casing 50 and the housing 10. Therefore, it is possible to suppress the situation where the vibration of the wire 41 is not suppressed by the rear retainer 60 and is transmitted to the terminal 40.

[0069] The first locking hook 81 has a protrusion 92 that abuts against the inner peripheral surface of the surrounding portion 51. With this configuration, for example, compared to a configuration where the flat surface of the locking hook contacts the inner peripheral surface of the surrounding portion 51, the first locking hook 81 can be pressed forcefully against the inner peripheral surface of the surrounding portion 51. Therefore, loosening between the housing 10 and the outer casing 50, and between the housing 10 and the rear retainer 60, can be more reliably prevented.

[0070] The compression rib 70 contacts the rear region 96 of the first locking hook 81 located on the back side of the protrusion 92. With this configuration, the portion of the first locking hook 81 with the protrusion 92 can be reliably clamped by the surrounding portion 51 and the compression rib 70. Therefore, loosening between the housing 10 and the outer casing 50, and between the housing 10 and the rear retainer 60, can be more reliably prevented.

[0071] The rear retainer 60 has a limiting portion 64 with a compression rib 70. The housing 10 has an inner connecting portion 24 that contacts the limiting portion 64 from the side opposite to the first locking hook 81 relative to the limiting portion 64. With this configuration, the limiting portion 64 can be restricted from displacement by the inner connecting portion 24 in such a way that it separates from the first locking hook 81 by the compression rib 70. Therefore, the first locking hook 81 can be reliably pressed by the compression rib 70.

[0072] When the housing 10 and outer casing 50 are in a semi-closed state, the limiting part 64 abuts against the front end face 81a of the first locking hook 81. With this configuration, it is possible to prevent the limiting part 64 from inserting into the inside of the wire receiving part 21 when the housing 10 and outer casing 50 are in a semi-closed state. Therefore, in the semi-closed state of the housing 10 and outer casing 50, it is possible to prevent the compression rib 70 from inserting into the inside of the first locking hook 81 and being flattened. Therefore, unnecessary wear on the rear retainer 60 can be suppressed.

[0073] In the above embodiment, the first locking hook 81 is provided with a protrusion 92. However, the first locking hook may not be provided with a protrusion; for example, the arm of the first locking hook may also contact the inner surface of the housing 50. In such a configuration, by contacting the compression rib 70 with the area on the back side of the portion of the first locking hook that contacts the inner surface of the housing 50, the first locking hook can be reliably clamped by the housing 50 and the compression rib 70.

[0074] In the above embodiment, the housing 10 is formed such that the wire 41 is led out in the -X direction. However, the housing may also be formed such that the wire is led out in a direction that crosses the X direction. That is, the wire receiving portion of the housing may not be provided behind the terminal support portion of the support terminal (in the -X direction).

[0075] In the above embodiment, the first locking hook 81 is configured to engage and disengage from the surrounding portion 51 in the Z direction, and the pressing rib 70 presses the first locking hook 81 in the Z direction. However, the pressing rib may also be configured to press the locking hook that engages and disengages from the housing in a direction other than the Z direction (e.g., the Y direction).

[0076] The above describes several implementation methods and variations. However, the implementation methods and variations are not limited to the examples described above. For example, multiple implementation methods can be combined with each other. The above implementation methods can also be implemented in various other ways, and various additions, omissions, substitutions, and changes can be made without departing from the spirit of this disclosure.
