AI Technical Summary

Technical Problem

In the conventional connector, when the elastic deformation directions of the locking sheet and the protrusion are the same, the protrusion and the spear-like portion may interfere with the retaining body, and affect the movement of the retaining body. Especially when the locking sheet is offset, the protrusion and the spear-like portion are displaced, resulting in interference problems when inserting the female terminal.

Method used

A retaining body with two locking sheets and a restricting portion is designed. The locking sheet is elastically deformed in the second direction. The ribs are displaced by abutting the housing to prevent interference with the spear-like portion, and ensure that the retaining body moves smoothly to the formal locking position.

Benefits of technology

The interference between the retaining body and the spear-shaped part is effectively suppressed, ensuring that the terminal is inserted and fixed smoothly in the connector, avoiding interference between the protrusion and the spear-shaped part, and improving the reliability of the connector.

Description

Technical Field

[0001] The present disclosure relates to a connector. Background Art

[0002] Conventionally, a connector described in Japanese Unexamined Patent Application Publication No. 2004-103551 (hereinafter referred to as Patent Document 1) has been known. The connector described in Patent Document 1 includes a female housing, a female terminal inserted into a cavity of the female housing, and a holding body mounted on a front surface of the female housing. In a state where the holding body is mounted at a temporary locking position, a protruding portion of the holding body retracts forward of a flexure space of a lance portion, allowing elastic deformation of the lance portion. Accordingly, insertion of the female terminal into the cavity is allowed. When the female terminal reaches a regular position within the cavity, the lance portion returns to its natural state and locks the female terminal. When the holding body is pressed from the temporary locking position to a formal locking position, the elastic deformation of the lance portion is restricted by the protruding portion protruding into the flexure space, and the female terminal is prevented from coming off within the cavity.

[0003] In the above-described connector, the holding body may include a front wall, a protruding portion extending rearward from the front wall, and a locking piece extending rearward from the front wall and locking to the female housing. The female housing may include a temporary locking portion and a formal locking portion. The temporary locking portion locks to the locking piece to hold the holding body at the temporary locking position, and the formal locking portion locks to the locking piece to hold the holding body at the formal locking position. During the process of moving the holding body from the temporary locking position to the formal locking position, the locking piece elastically deforms and passes over the formal locking portion. In the structure of Patent Document 1, the direction of elastic deformation of the lance portion is the vertical direction, and the direction of flexure deformation of the locking piece is the horizontal direction.

[0004] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2004-103551 Summary of the Invention Problems to be Solved by the Invention

[0005] Different from Patent Document 1, when two locking pieces are provided at upper and lower end portions of the holding body and the protruding portion is disposed at a position offset from an upper and lower center of the holding body, when the locking piece elastically deforms, the protruding portion continuous with the locking piece via the front wall may also deform in the same direction as the adjacent locking piece. For example, when the protruding portion is located at a position offset upward from the upper and lower center of the holding body, if the locking piece disposed at the upper end portion of the holding body elastically deforms upward, the protruding portion may also shift in an upwardly inclined manner. Further, when the flexure space of the lance portion into which the protruding portion should protrude is disposed below the lance portion, that is, when the lance portion flexes downward when the female terminal is inserted into the cavity, if the protruding portion shifts upward, the protruding portion cannot protrude into the flexure space and may interfere with the lance portion.

[0006] The present disclosure has been made based on the above circumstances, and aims to suppress the interference between the holding body and the lance portion when moving the holding body from the temporary locking position to the formal locking position. Solution to the problem

[0007] The connector of the present disclosure includes: a housing having a cavity extending in a first direction; terminals disposed in the cavity; and a holding body assembled to be movable in the first direction between a temporary locking position and a formal locking position relative to the housing. A lance portion is formed in the housing, the lance portion is disposed in the cavity and can be elastically deformed in a second direction orthogonal to the first direction. The holding body includes: two locking pieces that are locked to the housing; a restricting portion that allows insertion of the terminal into the cavity when the holding body is in the temporary locking position, and interferes with the lance portion to prevent the terminal from coming off in the cavity when the holding body is in the formal locking position; and a rib extending from the restricting portion, with the plane at the center between the two locking pieces disposed in the second direction as the central plane, and the restricting portion is disposed at a position offset from the central plane in the second direction. The lance portion interferes with the terminal during insertion of the terminal into the cavity and elastically deforms in the second direction to approach the central plane, and the two locking pieces interfere with the housing during movement of the holding body from the temporary locking position to the formal locking position and elastically deform in the second direction to move away from the central plane. During movement of the holding body from the temporary locking position to the formal locking position, the rib suppresses the restricting portion from shifting away from the central plane in the second direction by abutting against the housing. Advantageous effects of the invention

[0008] According to the present disclosure, interference between the holding body and the lance portion can be suppressed when moving the holding body from the temporary locking position to the formal locking position. Description of the drawings

[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. [1] The connector of the present disclosure includes: a housing having a cavity extending in a first direction; terminals disposed in the cavity; and a holding body assembled to be movable relative to the housing in a first direction between a temporary locking position and a formal locking position. A lance - shaped portion is formed in the housing, the lance - shaped portion is disposed in the cavity and can be elastically deformed in a second direction orthogonal to the first direction. The holding body includes: two locking pieces that are locked to the housing; a restricting portion that allows insertion of the terminals into the cavity when the holding body is in the temporary locking position and interferes with the lance - shaped portion to prevent the terminals from coming off in the cavity when the holding body is in the formal locking position; and a rib extending from the restricting portion. Taking the plane at the center between the two locking pieces disposed in the second direction as the central plane, the restricting portion is disposed at a position offset from the central plane in the second direction. The lance - shaped portion interferes with the terminals during insertion of the terminals into the cavity and elastically deforms in the second direction to approach the central plane. The two locking pieces interfere with the housing during the movement of the holding body from the temporary locking position to the formal locking position and elastically deform in the second direction to move away from the central plane. During the movement of the holding body from the temporary locking position to the formal locking position, the rib suppresses the restricting portion from shifting away from the central plane in the second direction by abutting against the housing.

[0011] According to such a structure, when the locking piece elastically deforms in the second direction away from the center plane during the process of moving the holding body from the temporary locking position to the formal locking position, the rib abuts against the housing, and the displacement of the restricting portion in the second direction away from the center plane can also be suppressed. Therefore, interference between the restricting portion and the lance portion can be avoided, and the holding body can be moved to the formal locking position.

[0012] [2] In the above [1], preferably, the restricting portion includes a first restricting portion and a second restricting portion disposed on the side opposite to the first restricting portion with respect to the center plane, the rib includes a first rib extending from the first restricting portion and a second rib extending from the second restricting portion, the cavity has a first cavity corresponding to the first restricting portion and a second cavity corresponding to the second restricting portion, and the lance portion includes a first lance portion disposed in the first cavity and a second lance portion disposed in the second cavity.

[0013] [3] In the above [1], preferably, the rib is disposed at a position overlapping the lance portion when viewed in the first direction.

[0014] According to such a structure, an increase in the arrangement space of the rib in the housing can be avoided, and the strength of the rib can be improved.

[0015] [4] In the above [1], preferably, the housing has a recess that opens on one side in the first direction and houses the rib, the rib has a guiding portion disposed at an end on the other side in the first direction, and the guiding portion is inclined so as to be closer to the center plane in the second direction as it faces the other side in the first direction.

[0016] According to such a structure, the guiding portion can guide the rib into the recess.

[0017] [5] In the above [1], preferably, the housing has a recess that opens on one side in the first direction and houses the rib, the terminal is inserted into the cavity from the other side in the first direction, the rib has a first surface that forms the cavity together with the housing, and an inclined portion that is continuous with the first surface and is disposed at an end on the other side in the first direction of the rib, the first surface faces the terminal from one side in a third direction orthogonal to both the first direction and the second direction, and the inclined portion is inclined so as to be located on one side in the third direction as it faces the other side in the first direction.

[0018] According to such a structure, the interference between the rib and the terminal can be suppressed by the inclined portion.

[0019] [Details of the embodiments of the present disclosure] Hereinafter, embodiments of the present disclosure will be described. The present disclosure is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, sometimes a part of the structure is enlarged or simplified and shown. In addition, regarding the dimensional ratios of the respective parts, they may be different in each drawing. In this specification, "orthogonal" includes not only the case where it is strictly orthogonal, but also the case where it is substantially orthogonal within the range where the functions and effects in this embodiment are achieved.

[0020] <Embodiment> Refer to Figures 1 to 11 Embodiments of the present disclosure will be described. In the following description, the direction indicated by the arrow line Z is taken as the upper direction, the direction indicated by the arrow line X is taken as the front direction, and the direction indicated by the arrow line Y is taken as the left direction for description. In this embodiment, the front-rear direction is an example of the first direction. The left-right direction is an example of the second direction. The up-down direction is an example of the third direction. In addition, regarding a plurality of identical members, sometimes only a part of the members are labeled with reference numerals, and the reference numerals of other members are omitted.

[0021] (Connector 10) As Figure 1 and Figure 4 shown, the connector 10 of this embodiment includes a housing 20, two terminals 11, and a holder 30.

[0022] (Terminal 11) As Figure 5 shown, the terminal 11 is a female terminal and includes a connection cylinder portion 12, a locking portion 13, and a wire crimping portion 14. The connection cylinder portion 12 is, for example, in the shape of a square cylinder. An elastic contact piece 12A is formed inside the connection cylinder portion 12. The locking portion 13 is formed at the rear end portion of the connection cylinder portion 12. The wire crimping portion 14 is connected to the rear of the connection cylinder portion 12. In addition, the connector 10 may further include terminals different from the terminal 11.

[0023] (Housing 20) As Figure 1 shown, the housing 20 has a housing main body 21 in a substantially block shape and two cavities 22 penetrating the housing main body 21 in the front-rear direction. In addition, as Figure 5As shown, a lance-shaped portion 23 that is disposed within the cavity 22 and is elastically deformable in the left-right direction, and a flexure space 24 into which the lance-shaped portion 23 can enter by elastic deformation are formed in the housing 20. The terminal 11 is inserted into the cavity 22 from the rear. During the process of inserting the terminal 11 into the cavity 22, the lance-shaped portion 23 elastically deforms by interfering with the connecting cylinder portion 12 and thus enters the flexure space 24. When the terminal 11 is inserted into the normal position within the cavity 22, the lance-shaped portion 23 elastically returns to its natural state and is locked to the locking portion 13 from the rear. Thereby, the terminal 11 can be prevented from falling off rearward from the cavity 22. In addition, the housing 20 may further have a cavity C1 different from the cavity 22 and a lance-shaped portion L1 (for example, a lance-shaped portion L1 that can be elastically deformed in the up-down direction) disposed within the cavity C1 and different from the lance-shaped portion 23.

[0024] The two cavities 22 are specifically a first cavity 22A and a second cavity 22B. The first cavity 22A is disposed at a position near the left end of the housing main body 21. The second cavity 22B is disposed at a position near the right end of the housing main body 21. The lance-shaped portion 23 disposed within the first cavity 22A is a first lance-shaped portion 23A. The lance-shaped portion 23 disposed within the second cavity 22B is a second lance-shaped portion 23B. In a state where the holding body 30 is assembled to the housing 20, the first lance-shaped portion 23A and the second lance-shaped portion 23B are disposed on opposite sides in the left-right direction with respect to the center plane CP of the holding body 30 described later. The first lance-shaped portion 23A is disposed to the left of the center plane CP, and the second lance-shaped portion 23B is disposed to the right of the center plane CP.

[0025] The flexure space 24 of the first lance-shaped portion 23A is disposed to the right of the first lance-shaped portion 23A. The first lance-shaped portion 23A elastically deforms to the right during the process of inserting the terminal 11 into the first cavity 22A. The flexure space 24 of the second lance-shaped portion 23B is disposed to the left of the second lance-shaped portion 23B. The second lance-shaped portion 23B elastically deforms to the left during the process of inserting the terminal 11 into the second cavity 22B. That is, the two lance-shaped portions 23 elastically deform in a direction approaching the center plane CP during the process of inserting the terminal 11 into the corresponding cavities 22 respectively.

[0026] As Figure 8 shown, the housing 20 has a recess 25 for housing a rib 36 of the holding body 30 described later. The housing 20 has a first opposed surface 26 that faces the terminal 11 from below among the surfaces constituting the cavity 22. The recess 25 is recessed downward from the first opposed surface 26. As Figure 10 shown, the recess 25 is open at the front.

[0027] As Figure 1 and Figure 5As shown, the housing 20 includes a temporary locking portion 27 and a formal locking portion 28 that protrude from the left and right side surfaces of the housing body 21. The temporary locking portion 27 is disposed forward of the formal locking portion 28. The temporary locking portion 27 is disposed above the formal locking portion 28.

[0028] (Holder 30) As Figure 2 and Figure 3 shown, the holder 30 includes a base wall 31, two locking pieces 32, two restricting portions 35, and two ribs 36. The base wall 31 is in the form of a thin plate in the front-rear direction. A through hole 31A penetrating the base wall 31 in the front-rear direction is provided in the holder 30. As Figure 6 shown, the through hole 31A is disposed at a position communicating with the cavity 22 of the housing 20.

[0029] As Figure 2 and Figure 3 shown, the two locking pieces 32 extend rearward from the left and right end portions of the base wall 31. The locking piece 32 is in the form of a thin plate in the left-right direction. Here, as Figure 2 shown, the plane disposed at the center between the two locking pieces 32 in the left-right direction is defined as the center plane CP. The center plane CP is a plane orthogonal to the left-right direction. As Figure 3 shown, a locking groove 33 recessed from the side surface closer to the center plane CP of the locking piece 32 is formed in the locking piece 32. The locking groove 33 extends in the front-rear direction and has two upper and lower ones formed. The locking groove 33 has a first locking groove 33A and a second locking groove 33B disposed below the first locking groove 33A. A locking protrusion 34 extending from the bottom surface of the locking groove 33 in the direction approaching the center plane CP in the left-right direction is formed at the rear end of the locking groove 33.

[0030] The locking piece 32 can be elastically deformed in the left-right direction. When the holder 30 is assembled to the housing 20, the two locking pieces 32 are respectively disposed outside the left and right side surfaces of the housing body 21, and the holder 30 is pressed rearward. When the holder 30 is pressed rearward, first, the temporary locking portion 27 and the locking protrusion 34 are engaged, and the two locking pieces 32 are elastically deformed in a direction away from the center plane CP in the left-right direction. When the holder 30 is further pressed rearward, the locking protrusion 34 passes over the temporary locking portion 27, and the temporary locking portion 27 enters the first locking groove 33A. And, the locking piece 32 returns to its natural state, and the locking protrusion 34 is disposed between the temporary locking portion 27 and the formal locking portion 28 (refer to Figure 5 ). Figure 5 The position of the holder 30 shown is the temporary locking position. The locking protrusion 34 is locked to the rear surface of the temporary locking portion 27. The locking protrusion 34 is locked to the front surface of the formal locking portion 28. Therefore, the holder 30 and the housing 20 are locked in the front-rear direction and held at the temporary locking position.

[0031] When the holder 30 is further pressed rearward from the temporary locking position, the official locking portion 28 and the locking projection 34 are engaged, and the two locking pieces 32 are elastically deformed in the left-right direction so as to move away from the center plane CP. When the holder 30 is further pressed rearward, the locking projection 34 passes over the official locking portion 28, and the official locking portion 28 enters the second locking groove 33B. Further, the locking piece 32 returns to its natural state, and the locking projection 34 is disposed in front of the official locking portion 28 (see Figure 7 ). Figure 6 And Figure 7 The position of the holder 30 shown is the official locking position. As shown in Figure 7 , the locking projection 34 is locked to the rear surface of the official locking portion 28. In addition, the base wall 31 is locked to the front surface of the housing main body 21. Therefore, the holder 30 is locked to the housing 20 in the front-rear direction and is held at the official locking position.

[0032] As shown in Figure 2 , the restricting portion 35 is disposed closer to the center plane CP with respect to the through hole 31A. The restricting portion 35 extends rearward from the base wall 31. As shown in Figure 5 , when the holder 30 is in the temporary locking position, the restricting portion 35 is disposed in front of the flexure space 24. The restricting portion 35 does not enter the flexure space 24. Therefore, the lance portion 23 is elastically deformed in the left-right direction toward the center plane CP and can enter the flexure space 24. Accordingly, the insertion of the terminal 11 into the cavity 22 is permitted.

[0033] On the other hand, as shown in Figure 6 , when the holder 30 is in the official locking position, the restricting portion 35 enters the flexure space 24. In a state where the restricting portion 35 is disposed in the flexure space 24, the lance portion 23 interferes with the restricting portion 35, and thus the elastic deformation of the lance portion 23 is restricted. That is, the terminal 11 is secondarily locked by the holder 30. Therefore, it is possible to prevent the terminal 11 disposed at the normal position in the cavity 22 from falling rearward from the cavity 22.

[0034] The two restricting portions 35 are specifically a first restricting portion 35A and a second restricting portion 35B. The first restricting portion 35A is disposed to the left of the center plane CP. The second restricting portion 35B is disposed to the right of the center plane CP. When the holder 30 is in the official locking position, the first restricting portion 35A enters the flexure space 24 of the first lance portion 23A, and the second restricting portion 35B enters the flexure space 24 of the second lance portion 23B. Further, as shown in Figure 5 , the holder 30 may further include a restricting portion R1 (for example, a restricting portion R1 that restricts the elastic deformation of the restricting lance portion L1) different from the restricting portion 35.

[0035] As shown inFigure 2 and Figure 3 As shown in Figure 3 , rib 36 extends from the restricting portion 35. In the present embodiment, rib 36 extends from the restricting portion 35 in a direction away from the center plane CP in the left - right direction. Further, rib 36 may also extend rearward from the base wall 31. The rib 36 extending from the first restricting portion 35A is the first rib 36A. The rib 36 extending from the second restricting portion 35B is the second rib 36B.

[0036] As Figure 8 and Figure 11 shown, when the holding body 30 is in the temporary locking position, rib 36 is disposed within the recess 25. As Figure 8 shown, the recess 25 has an abutting surface 25A that faces rib 36 in the left - right direction. Rib 36 approaches the abutting surface 25A and is disposed at a position closer to the center plane CP than the abutting surface 25A in the left - right direction. Further, when the holding body 30 is in the formal locking position and when the holding body 30 is moving from the temporary locking position to the formal locking position, rib 36 is also disposed within the recess 25 and faces the abutting surface 25A in the left - right direction. As Figure 6 and Figure 9 shown, when the holding body 30 is in the formal locking position, rib 36 is disposed at a position where it does not contact the lance - shaped portion 23.

[0037] When moving the holding body 30 from the temporary locking position (refer to Figure 5 ) to the formal locking position (refer to Figure 6 ), the locking piece 32 elastically deforms in the left - right direction so as to move away from the center plane CP. Here, since the restricting portion 35 is connected to the locking piece 32 via the base wall 31, the tip portion of the restricting portion 35 displaces away from the base end portion in a manner following the elastic deformation of the locking piece 32, away from the center plane CP. In particular, when moving the holding body 30 by pressing only the left - right central portion of the base wall 31 rearward with a finger or the like, the left - right end portions of the base wall 31 deform in a manner of warping relative to the left - right central portion, so that the restricting portion 35 easily displaces away from the center plane CP. When such a displacement of the restricting portion 35 occurs, the restricting portion 35 contacts the lance - shaped portion 23 in the front - rear direction, hindering the movement of the holding body 30 to the formal locking position. However, in the present embodiment, by the rib 36 abutting against the abutting surface 25A, the displacement of the restricting portion 35 away from the center plane CP is restricted. Therefore, when moving the holding body 30 from the temporary locking position to the formal locking position, interference between the restricting portion 35 and the lance - shaped portion 23 can be suppressed. Therefore, the holding body 30 can reach the formal locking position.

[0038] As Figure 9As shown, the rib 36 may also have a portion that faces the lance portion 23 in the front-rear direction. With such a structure, it is possible to prevent the installation space of the rib 36 in the housing 20 from becoming large, and the volume of the rib 36 can be increased to improve the strength of the rib 36. As a result, it is possible to further suppress the displacement of the restricting portion 35 away from the center plane CP.

[0039] As Figure 10 shown, a guiding portion 37 is formed at the rear end portion of the rib 36. The guiding portion 37 is disposed at the end portion of the rib 36 that extends from the restricting portion 35. The guiding portion 37 is inclined so as to be closer to the center plane CP in the left-right direction as it faces the rear. By providing the guiding portion 37, the rib 36 can easily enter the recess 25.

[0040] As Figure 8 and Figure 5 shown, the restricting portion 35 and the rib 36 together with the housing 20 form a cavity 22 in a region in front of the lance portion 23. As Figure 8 shown, the rib 36 has a first surface 38 that constitutes the cavity 22. The first surface 38 faces the terminal 11 from below. The first surface 38 is disposed at substantially the same height as the first opposing surface 26. As Figure 11 shown, at the rear end portion of the rib 36, an inclined portion 39 is continuously formed with the first surface 38. The inclined portion 39 descends and inclines more as it faces the rear. By providing the inclined portion 39, it is possible to suppress interference between the front end of the terminal 11 and the rear end of the rib 36 in the front-rear direction during the process of inserting the terminal 11 into the cavity 22.

[0041] (Function and Effect of the Embodiment) (1) The connector 10 of the embodiment includes: a housing 20 having a cavity 22 extending in a first direction (front-rear direction); terminals 11 disposed in the cavity 22; and a holding body 30 assembled to be movable relative to the housing 20 in the first direction between a temporary locking position and a formal locking position. A spear-shaped portion 23 is formed in the housing 20. The spear-shaped portion 23 is disposed in the cavity 22 and can be elastically deformed in a second direction (left-right direction) orthogonal to the first direction. The holding body 30 includes: two locking pieces 32 that are locked to the housing 20; a restricting portion 35 that allows the insertion of the terminals 11 into the cavity 22 when the holding body 30 is in the temporary locking position, and interferes with the spear-shaped portion 23 to prevent the terminals 11 from coming off in the cavity 22 when the holding body 30 is in the formal locking position; and a rib 36 extending from the restricting portion 35. Taking the plane at the center between the two locking pieces 32 disposed in the second direction as the center plane CP, the restricting portion 35 is disposed at a position offset from the center plane CP in the second direction. The spear-shaped portion 23 interferes with the terminals 11 during the insertion of the terminals 11 into the cavity 22 and is elastically deformed in the second direction so as to approach the center plane CP. The two locking pieces 32 interfere with the housing 20 during the movement of the holding body 30 from the temporary locking position to the formal locking position and are elastically deformed in the second direction so as to move away from the center plane CP. During the movement of the holding body 30 from the temporary locking position to the formal locking position, the rib 36 abuts against the housing 20, thereby suppressing the displacement of the restricting portion 35 in the second direction away from the center plane CP.

[0042] According to such a structure, when the locking piece 32 is elastically deformed in the second direction away from the center plane CP during the movement of the holding body 30 from the temporary locking position to the formal locking position, the rib 36 abuts against the housing 20, and the displacement of the restricting portion 35 in the second direction away from the center plane CP can also be suppressed. Therefore, the interference between the restricting portion 35 and the spear-shaped portion 23 can be avoided, and the holding body 30 can be moved to the formal locking position.

[0043] (2) In the embodiment, the restricting portion 35 includes a first restricting portion 35A and a second restricting portion 35B disposed on the side opposite to the first restricting portion 35A with respect to the center plane CP. The rib 36 includes a first rib 36A extending from the first restricting portion 35A and a second rib 36B extending from the second restricting portion 35B. The cavity 22 has a first cavity 22A corresponding to the first restricting portion 35A and a second cavity 22B corresponding to the second restricting portion 35B. The spear-shaped portion 23 includes a first spear-shaped portion 23A disposed in the first cavity 22A and a second spear-shaped portion 23B disposed in the second cavity 22B.

[0044] (3) In the embodiment, the rib 36 is disposed at a position overlapping the spear-shaped portion 23 when viewed in the first direction (front view).

[0045] According to such a structure, it is possible to avoid an increase in the space for arranging the rib 36 in the housing 20 and to improve the strength of the rib 36.

[0046] (4) In the embodiment, the housing 20 includes a recess 25 that is open on one side (front side) in the first direction and houses the rib 36. The rib 36 has a guiding portion 37 disposed at the end on the other side (rear side) in the first direction. The guiding portion 37 is inclined so as to be closer to the center plane CP in the second direction as it approaches the other side in the first direction.

[0047] According to such a structure, the guiding portion 37 can guide the rib 36 into the recess 25.

[0048] (5) In the embodiment, the housing 20 includes a recess 25 that is open on one side in the first direction and houses the rib 36. The terminal 11 is inserted into the cavity 22 from the other side in the first direction. The rib 36 has a first surface 38 that forms the cavity 22 together with the housing 20, and an inclined portion 39 that is continuous with the first surface 38 and is disposed at the end on the other side in the first direction of the rib 36. The first surface 38 faces the terminal 11 from one side (lower side) in the third direction that is orthogonal to both the first direction and the second direction. The inclined portion 39 is inclined so as to be located on one side in the third direction as it approaches the other side in the first direction.

[0049] According to such a structure, the inclined portion 39 can suppress interference between the rib 36 and the terminal 11.
