Description

Technical Field

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

[0002] The connector disclosed in Patent Document 1 comprises a terminal part, a connector housing for accommodating the terminal part, and a retaining body arranged on the connector housing so as to be movable to a temporary locking state and a formal locking state. The connector housing is provided with a retaining body mounting hole which is open on the bottom surface and both side surfaces. A formal locking portion and a temporary locking portion (hereinafter referred to as "locking portion") are protrudingly provided on the side surface in front of the retaining body mounting hole. The retaining body comprises: a base body, which is arranged in the retaining body mounting hole and can lock the terminal part; and a side wall portion, which protrudes from the base body and covers the side surface. A locked portion which can be locked with the locking portion is provided on the inner surface of the side wall portion. The retaining body is inserted into the retaining body mounting hole through the opening of the bottom surface and moves upward from the temporary locking state to the formal locking state. When the retaining body is assembled to the temporary locking state (when inserted into the retaining body insertion hole) and when it moves from the temporary locking state to the formal locking state, the locked portion straddles the locking portion, and the side wall portion is elastically deformed outward with the connection part with the base body as a fulcrum. Patent Documents 2 and 3 also disclose connectors including a retaining body. Prior art literature Patent Literature

[0003] Patent Document 1: Japanese Patent Application Publication No. 2005-222758 Patent Document 2: Japanese Patent Application Publication No. 2005-302350 Patent Document 3: Japanese Patent Application Publication No. 2017-27678 Summary of the invention Problems to be solved by the invention

[0004] In the case of Patent Document 1, the locking portion is arranged close to the mounting hole of the retaining body. The fulcrum of the flexing movement of the side wall portion is also close to the mounting hole of the retaining body. Assuming that during the movement of the retaining body, the locked portion and the rear end portion of the locking portion (the end portion facing the opening side of the mounting hole of the retaining body) strongly interfere with each other and step over, a large stress acts on the rear end portion of the locking portion. In contrast, if the locking portion is arranged away from the mounting hole of the retaining body, the strong interference between the locked portion and the rear end portion of the locking portion can be avoided. However, when the locking position of the locked portion and the locking portion is far away from the fulcrum of the flexing movement of the side wall portion, it is possible that sufficient locking force cannot be ensured between the locked portion and the locking portion. As a result, there is a problem of reduced holding force of the retaining body relative to the connector housing.

[0005] Therefore, an object of the present invention is to provide a connector capable of achieving both operability and holding force of a holding body. Solutions to Solve Problems

[0006] The connector of the present invention comprises a terminal part, a shell for accommodating the terminal part, and a retaining body arranged on the shell so as to be movably disposed between a temporary retaining position and a formal retaining position, the shell having a one side, a side intersecting the one side, a retaining body mounting hole opened on the one side and the side surface, and a retaining portion protruding from the side surface, the retaining body comprising: a main body portion, which is arranged on the inner side of the retaining body mounting hole and can retain the terminal part; and a side plate portion, which protrudes from the main body portion in a direction intersecting with the moving direction of the retaining body and covers the side surface from the outside, the side plate portion having a retaining portion protruding from the inner surface opposite to the side surface, the retaining portion being retained by the retaining portion in at least one of the temporary retaining position and the formal retaining position, and the retaining portion having an inclined portion inclined in a direction away from the opening of the retaining body mounting hole on the end face on the opening side of the retaining body mounting hole.

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The connector of the present invention, (1) It comprises a terminal part, a shell for accommodating the terminal part, and a retaining body arranged on the shell so as to be movably disposed between a temporary retaining position and a formal retaining position, the shell having a one side, a side intersecting the one side, a retaining body mounting hole opened on the one side and the side surface, and a retaining portion protruding from the side surface, the retaining body comprising: a main body portion, which is arranged on the inner side of the retaining body mounting hole and can retain the terminal part; and a side plate portion, which protrudes from the main body portion in a direction intersecting with the moving direction of the retaining body and covers the side surface from the outside, the side plate portion having a retaining portion protruding from the inner surface opposite to the side surface, the retaining portion being retained by the retaining portion at at least one of the temporary retaining position and the formal retaining position, and the retaining portion having an inclined portion on the end face facing the opening side of the retaining body mounting hole and inclined in a direction away from the opening of the retaining body mounting hole.

[0010] When the retaining body is assembled to the temporary locking position or moved from the temporary locking position to the formal locking position, the side plate portion is elastically deformed, and the locked portion straddles the locking portion. When the locked portion contacts the inclined portion, the stress acting on the locking portion is dispersed in the length direction of the inclined portion (the direction away from the opening of the retaining body mounting hole). Therefore, the stress is not concentrated on the corners of the locking portion, etc., and the side plate portion can be elastically deformed smoothly, which can improve the operability of the retaining body. In addition, the locking portion can be extended toward the opening side of the retaining body mounting hole in accordance with the length of the inclined portion, so that the required locking force can be ensured between the locking portion and the locked portion, which can improve the holding force of the retaining body.

[0011] (2) In the connector described in (1) above, preferably, the sloped portion is inclined at an angle of 45 degrees or less with respect to a surface direction of the side surface.

[0012] If the angle of inclination of the inclined surface is below 45 degrees, the length of the inclined surface can be lengthened, so the dispersion effect of the stress acting on the stopper can be improved. In addition, the length of the stopper including the inclined surface can be lengthened, so sufficient stopper force can be ensured between the stopper and the stopper.

[0013] (3) In the connector described in (1) or (2) above, preferably, the side surface has a pressing portion at a position on the side opposite to the opening side of the retaining body mounting hole across the locking portion, the pressing portion is opposed to the top end portion of the side plate portion in the protruding direction from the outside, and the side plate portion is configured to be able to shift to a cantilever state configured to be away from the pressing portion, and to a double support state in which the locked portion straddles the locking portion and is configured to be in contact with the pressing portion.

[0014] The top end of the protruding direction of the side plate portion contacts the pressing portion, thereby limiting the side plate portion from floating up from the side. In addition, when the retaining body is assembled to the temporary locking position or moves from the temporary locking position to the formal locking position, if the locked portion straddles the locking portion, the side plate portion can be elastically deformed into a double-supported state with the connection portion with the main body side and the contact portion with the pressing portion as fulcrums. As the locked portion passes over the locking portion, the side plate portion quickly elastically recovers, and the locked state of the locked portion and the locking portion can be achieved with a sense of rhythm. When the retaining body starts to be assembled to the temporary locking position or starts to move from the temporary locking position to the formal locking position, the side plate portion is maintained in a cantilever state, thereby reducing the assembly resistance or movement resistance compared to the case of the double-supported state.

[0015] (4) In the connector described in any one of (1) to (3) above, it is preferred that the locking portion is composed of a temporary locking portion that locks the locked portion at the temporary locking position and a formal locking portion that locks the locked portion at the formal locking position, and the inclined portion is provided on both the formal locking portion and the temporary locking portion.

[0016] When the retaining body is assembled to the temporary locking position, the locked portion straddles the temporary locking portion, and when the retaining body is moved to the formal locking position, the locked portion straddles the formal locking portion. Regardless of the state of the retaining body during assembly and during movement, as described in (1) above, the operability and holding force of the retaining body can be improved by the inclined portion.

[0017] (5) In the connector described in (4) above, preferably, the inclined surface portions of the permanent locking portion and the temporary locking portion have the same inclination angle with respect to the surface direction of the side surface.

[0018] When the locked portion straddles the temporary locking portion and the formal locking portion, the side plate portion can be elastically deformed in the same manner, so the smoothness of the flexing action of the side plate portion can be ensured. Further, the mold structure for molding the inclined portion will not become complicated.

[0019] [Details of Embodiments of the Invention] Specific examples of the present invention are described below with reference to the drawings. In addition, the present disclosure is not limited to the examples, but is shown by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

[0020] <Implementation Method 1> like Figure 3As shown in FIG. 1 , the connector 10 of the first embodiment includes a housing 20, a terminal part 90 housed in the housing 20, and a retaining body 60 movably assembled to the housing 20. The housing 20 can be mated with a mating connector (not shown). In the following description, regarding the front-to-back direction, the side of the housing 20 facing the mating connector at the beginning of mating is referred to as the front side. The up-down direction is denoted by Figure 7 and Figure 8 The up-down direction of each figure other than the above is used as a reference. The up-down direction is synonymous with the height direction. The left-right direction is a direction perpendicular to the front-back direction and the up-down direction. The left-right direction is synonymous with the width direction. In each figure, X is used to represent the front, Y is used to represent the side (here, the right when viewed from the front), and Z is used to represent the top. These direction references are for convenience and may not be consistent with the direction references when the connector 10 is mounted on a vehicle, etc., not shown in the figure.

[0021] (Housing 20 and terminal parts 90) The housing 20 is made of synthetic resin, such as Figure 3 As shown, it has a housing body 21, a locking arm 22 protruding from the upper surface 26 of the housing body 21, and a front member 23 that is separate from the housing body 21 and covers the front surface of the housing body 21. The locking arm 22 can be elastically deformed in the vertical direction to lock the other connector (not shown) and keep the other connector and the housing 20 in a mating state.

[0022] The housing body 21 has a plurality of cavities 24 penetrating in the front-rear direction, and elastically deformable lances 25 protruding forward from the inner walls of the cavities 24 . The terminal part 90 is made of conductive metal and is inserted into the corresponding cavity 24 from the rear. The terminal part 90 is illustrated as a female terminal and has a cylindrical box part 91 at the front. The box part 91 accommodates the tab of the other terminal part (not shown) and is electrically connected to the other terminal part. The rear part of the terminal part 90 is crimped with the terminal part of the wire 100 to be electrically and mechanically connected. The front member 23 stops the box part 91 in front and restricts the terminal part 90 from falling off in the front direction.

[0023] The housing body 21 has an outer surface facing outward. Figure 1 and Figure 2 As shown, the outer surface of the housing body 21 includes an upper surface 26 connected to the locking arm 22, a surface 27 as a bottom surface (lower surface), and a pair of side surfaces 28 (only the side surface 28 on the right side is shown) intersecting the upper surface 26 and the surface 27 and facing the left and right sides. The surface 27 is horizontally arranged along the front-back direction. The side surfaces 28 are vertically arranged along the up-down direction.

[0024] The housing body 21 has a retainer mounting hole 29 opened on one surface 27 and each side surface 28. Figure 3As shown, the holder mounting hole 29 communicates with each cavity 24 in the housing body 21 and is arranged behind each lance 25. A main body 61 of the holder 60 described later is inserted into the holder mounting hole 29 from an opening of one surface 27 of the holder mounting hole 29.

[0025] like Figure 1 , Figure 7 and Figure 8 As shown, each side surface 28 of the housing body 21 has an opposing surface 31 along the up-down direction and the front-back direction at a position facing forward from the opening of the holding body mounting hole 29. The opposing surface 31 is arranged opposite to the side plate portion 62 described later of the holding body 60. Each side surface 28 of the housing body 21 has an outer side surface 32 arranged on the left and right outer sides of the opposing surface 31 in front of the opposing surface 31.

[0026] In addition, if Figure 7 and Figure 8 As shown in the figure, each side surface 28 of the housing body 21 has a step-shaped pressing portion 33 between the facing surface 31 and the outer side surface 32. The pressing portion 33 is an inverted tapered surface that is inclined backward from the facing surface 31 toward the outer side surface 32. On each side surface 28 of the housing body 21, a groove portion 44 having a V-shaped cross section and a shape of a part of a dovetail groove is formed by the pressing portion 33 and the facing surface 31. The pressing portion 33 is arranged in a manner to cover the front end portion of the side plate portion 62 of the retaining body 60 from the outside, thereby restricting the side plate portion 62 from floating outward.

[0027] like Figure 4 As shown in the figure, the opposing surface 31 of each side surface 28 of the shell body 21 is protrudingly provided with a stopper 34, 35. The stopper 34, 35 is composed of a formal stopper 34 and a temporary stopper 35 arranged below the formal stopper 34. The formal stopper 34 and the temporary stopper 35 are both rib-shaped extending in the front-back direction. The thickness of the temporary stopper 35 in the up-down direction is greater than the thickness of the formal stopper 34 in the up-down direction. The formal stopper 34 and the temporary stopper 35 have the following functions: they are stopped at the later-described stopper 65 of the retaining body 60, and the retaining body 60 is respectively kept at the formal stopper position and the temporary stopper position relative to the shell 20. In addition, in the following description, when it is not necessary to distinguish the formal stopper 34 and the temporary stopper 35 from each other, the formal stopper 34 and the temporary stopper 35 are simply referred to as the stopper 34, 35.

[0028] The locking portions 34 and 35 are arranged at a portion above the upper and lower centers of the opposing surface 31. In addition, the locking portions 34 and 35 are arranged close to the retaining body mounting hole 29. The rear surfaces of the locking portions 34 and 35 are end surfaces facing the opening side of the side surface 28 of the retaining body mounting hole 29. An inclined portion 36 inclined toward the front away from the retaining body mounting hole 29 is formed on the rear surfaces of the locking portions 34 and 35. The inclined portion 36 is inclined at an angle of less than 45 degrees relative to the surface direction (front-rear direction) of the opposing surface 31. The inclined portions 36 of the formal locking portion 34 and the temporary locking portion 35 are inclined at the same inclination angle.

[0029] A second inclined surface 37 is formed on the lower surface of the stopper 34, 35, which is inclined upward toward the top end surface of the protruding direction of the stopper 34, 35. A third inclined surface 38 is formed on the upper surface of the formal stopper 34, which is inclined downward toward the top end surface of the protruding direction of the formal stopper 34. The top end surface of the protruding direction of the stopper 34, 35 is a vertical surface extending elongated in the front-to-back direction. The upper surface of the temporary stopper 35 is a horizontal surface extending elongated in the front-to-back direction.

[0030] The locking portions 34 and 35 have a linear ridge portion 39 that is inclined upward from the rear end of the locking portions 34 and 35 to the front between the inclined portion 36 and the second inclined portion 37. The ridge portion 39 of the temporary locking portion 35 is formed longer than the ridge portion 39 of the formal locking portion 34. The formal locking portion 34 has an upper ridge portion 41 that is inclined downward from the rear end of the formal locking portion 34 to the front between the inclined portion 36 and the third inclined portion 38. The front surfaces of the locking portions 34 and 35 are vertical surfaces that extend slenderly in the up-down direction.

[0031] (Retaining body 60) The retaining body 60 is made of synthetic resin, and although the entire body is not shown, Figure 5 and Figure 6 As shown, it has a main body 61 extending long in the left-right direction, and a pair of side plates 62 (only one side plate 62 is shown) protruding forward from the left and right ends of the main body 61. Figure 3 As shown, the main body 61 is disposed inside the retaining body mounting hole 29, and moves in the vertical direction between the temporary locking position and the formal locking position inside the retaining body mounting hole 29. Figure 7 and Figure 8 As shown, each side plate portion 62 is arranged so as to cover each facing surface 31 of the housing 20 .

[0032] like Figure 5As shown, a plurality of through holes 63 penetrating in the front-to-back direction are formed in the main body 61. The through holes 63 are arranged in the left-right direction in the main body 61. The main body 61 has a plurality of anti-slip portions 64 protruding from the inner lower surface of each through hole 63. The anti-slip portions 64 are also arranged in the left-right direction on the upper surface of the main body 61. When the main body 61 is arranged inside the retaining body mounting hole 29, each through hole 63 is arranged to communicate with the cavity 24 of the lower layer. Each anti-slip portion 64 is arranged corresponding to each cavity 24 of the upper and lower layers.

[0033] When the retaining body 60 is located at the temporary locking position relative to the housing 20, the anti-detachment portion 64 is configured to retreat from the insertion path of the terminal part 90, allowing the terminal part 90 to be inserted into the cavity 24. Figure 4 As shown, when the retaining body 60 is in the formal locking position relative to the housing 20, the anti-dropout portion 64 is configured to enter the insertion path of the terminal part 90 and can be locked on the rear surface of the box part 91. The terminal part 90 is held in the cavity 24 in a prevented state by the anti-dropout portion 64.

[0034] like Figure 6 As shown in FIG. 1 , each side plate portion 62 is in the shape of a plate with the plate surface facing the left-right direction and has a rectangular shape when viewed from the side. Each side plate portion 62 can be elastically deformed in the left-right direction with the rear end portion connected to the main body portion 61 as a fulcrum. Figure 7 and Figure 8 As shown in FIG. 1 , a pressed portion 68 that is inclined rearward as it goes to the left and right outer sides is formed on the front end surface of each side plate portion 62. The pressed portion 68 is arranged so as to cover the pressed portion 33.

[0035] like Figure 6 As shown in the figure, a stopped portion 65 is protrudingly provided on the inner surface of each side plate portion 62. The stopped portion 65 is in the shape of a rib extending in the front-rear direction, and is formed along the upper end portion of the inner surface of each side plate portion 62. An inclined surface 66 is formed on the upper surface of the stopped portion 65, which is inclined downward from the upper end surface of each side plate portion 62 toward the top end surface in the protruding direction. The lower surface of the stopped portion 65 is a horizontal surface extending in the front-rear direction.

[0036] A longitudinal rib 67 extending in the up-down direction is protrudingly provided on the inner surface of each side plate portion 62. The upper end of the longitudinal rib 67 is integrally connected to the front end of the clamped portion 65. The front surface of the longitudinal rib 67 faces the front end of the side plate portion 62. In addition, a transverse rib 69 extending in the front-to-back direction is protrudingly provided on the inner surface of each side plate portion 62. The front end of the transverse rib 69 is integrally connected to the lower end of the longitudinal rib 67. The lower surface of the transverse rib 69 faces the lower end of the side plate portion 62. On the inner surface of each side plate portion 62, a door-shaped frame portion 71 is formed integrally by the clamped portion 65, the longitudinal rib 67 and the transverse rib 69.

[0037] (Function of connector 10) The main body 61 of the retaining body 60 is inserted into the retaining body mounting hole 29 from below through the opening of the one surface 27 relative to the housing 20. During the assembly process of the retaining body 60, the inclined surface 66 of the locked portion 65 slides on the second inclined surface 37 of the temporary locking portion 35, and as shown in FIG. Figure 7 As shown, the side plate 62 slides on the inclined surface 36 of the temporary stop portion 35, so that the side plate 62 is elastically deformed to the left and right outer sides with the rear end portion as the fulcrum. The pressed portion 68 of the front end surface of the side plate 62 contacts the pressing portion 33 of the housing 20 from the left and right inner sides, limiting the side plate 62 from opening to the left and right outer sides. Through the contact position of the pressed portion 68 relative to the pressing portion 33 and the rear end portion as the fulcrum of the bending action, the side plate 62 is formed into a double-supported state of a double-supported beam in appearance. During the period when the side plate 62 is elastically deformed to form a double-supported state, the stress acting on the temporary stop portion 35 from the stop portion 65 is dispersed in the length direction of the inclined surface 36 and the ridge portion 39 (the direction away from the opening of the retaining body mounting hole 29). Therefore, no excessive stress is applied to the temporary stop portion 35. As a result, it is possible to prevent the temporary stop portion 35 from being cut or deformed by the stop portion 65 and causing the edge to collapse.

[0038] When the stopped portion 65 passes over the temporary stop portion 35, the side plate portion 62 quickly elastically returns to its original state (a natural state without elastic deformation). Figure 1 As shown, the locked portion 65 is embedded between the temporary locking portion 35 and the formal locking portion 34. At this time, the lower surface of the locked portion 65 is arranged opposite to the upper surface of the temporary locking portion 35, and the upper surface of the locked portion 65 is arranged opposite to the lower surface of the formal locking portion 34. Thus, the holding body 60 is held at the temporary locking position relative to the housing 20.

[0039] When the retaining body 60 is located at the temporary locking position relative to the housing 20, the lower end of the retaining body 60 is configured to protrude downward from the one surface 27 of the housing body 21. Figure 8 As shown, the pressed portion 68 of the side plate portion 62 is arranged away from the pressing portion 33 of the housing 20, and the double support state of the side plate portion 62 is released. In the temporary stop position, the side plate portion 62 forms a cantilever state that can be elastically deformed only with the rear end portion connected to the main body 61 as a fulcrum. When the retaining body 60 is located at the temporary stop position relative to the housing 20, the terminal parts 90 are inserted into each cavity 24 from the rear. The terminal parts 90 are connected to the terminal portion of the wire 100 in advance.

[0040] After the terminal parts 90 are inserted into the cavities 24, the retaining body 60 is pushed up. Then, the locked portion 65 slides on the second inclined surface 37 and the inclined surface 36 of the formal locking portion 34, and the side plate portion 62 elastically deforms to the left and right sides with the rear end portion as a fulcrum (refer to Figure 7). As described above, the pressed portion 68 of the side plate portion 62 contacts the pressing portion 33 of the housing 20 from the left and right inner sides, thereby limiting the side plate portion 62 from opening to the left and right outer sides. During the period when the side plate portion 62 is elastically deformed to form a double-supported state, the stress acting on the formal locking portion 34 from the locked portion 65 is dispersed in the longitudinal direction of the inclined surface portion 36 and the ridge portion 39. Therefore, excessive stress is not applied to the formal locking portion 34. As a result, deformation (collapse) of the formal locking portion 34 can be prevented.

[0041] When the stopped portion 65 passes over the formal stopping portion 34, the side plate portion 62 quickly elastically returns to its original state (a natural state without elastic deformation). Figure 2 As shown, the locked portion 65 is embedded between the formal locking portion 34 and the stepped surface 43 defining the upper end of the opposing surface 31. At this time, the lower surface of the locked portion 65 is arranged opposite to the upper surface of the formal locking portion 34, and the upper surface of the locked portion 65 is arranged opposite to the stepped surface 43. As a result, the retaining body 60 is maintained at the formal locking position relative to the housing 20. The side plate portion 62 forms a cantilevered state in the form of a cantilever beam at the formal locking position (see Figure 8 ). And, when the retaining body 60 reaches the formal locking position, as shown in Figure 3 As shown, the retaining portion 64 is arranged so as to lock the terminal fitting 90. The lower surface of the holding body 60 and the one surface 27 of the housing body 21 are arranged without a step.

[0042] As described above, the retaining body 60 of the first embodiment includes: a main body 61, which is arranged inside the retaining body mounting hole 29 and can lock the terminal part 90; and a side plate 62, which protrudes from the main body 61 in a cantilever beam shape in a direction intersecting the moving direction of the retaining body 60 and covers the side surface 28 of the housing 20 from the outside. The side plate 62 includes a locked portion 65 protrudingly provided on the inner surface opposite to the side surface 28 of the housing 20, and the locked portion 65 is locked to the locking portions 34 and 35 at two positions: a temporary locking position and a formal locking position. The locking portions 34 and 35 have an inclined surface 36 inclined in a direction away from the opening of the retaining body mounting hole 29 on the end surface facing the opening side of the retaining body mounting hole 29.

[0043] When the retaining body 60 is assembled to the temporary locking position or moved from the temporary locking position to the formal locking position, the side plate portion 62 is elastically deformed, and the locked portion 65 straddles the locking portions 34 and 35. When the locked portion 65 contacts the inclined portion 36, the stress acting on the locking portions 34 and 35 is dispersed in the length direction of the inclined portion 36. Therefore, the stress is not concentrated on a part of the side plate portion 62, and the side plate portion 62 can be elastically deformed smoothly, which can improve the operability of the retaining body 60. In addition, the locking portions 34 and 35 can be extended to the opening side of the retaining body mounting hole 29 according to the length of the inclined portion 36, so the required locking force can be ensured between the locking portions 34 and 35 and the locked portion 65, which can improve the holding force of the retaining body 60.

[0044] In addition, the inclined surface portion 36 is inclined at an angle of 45 degrees or less relative to the surface direction of the side surface 28 of the housing 20. In this way, the length of the inclined surface portion 36 can be increased, so that the dispersion effect of the stress acting on the locking portions 34 and 35 can be improved. In addition, the length of the locking portions 34 and 35 including the inclined surface portion 36 can also be increased, so that sufficient locking force can be ensured between the locking portions 34 and 35 and the locked portion 65.

[0045] Furthermore, the side surface 28 of the housing 20 has a pressing portion 33 that is opposed to the top end (pressed portion 68) of the side plate portion 62 in the protruding direction from the outside at a position on the side opposite to the opening side of the retaining body mounting hole 29 across the locking portions 34 and 35. The side plate portion 62 is configured to be displaceable to a cantilever state in which it is arranged away from the pressing portion 33, and a double support state in which it is arranged in contact with the pressing portion 33 by the locked portion 65 straddling the locking portions 34 and 35.

[0046] The pressed portion 68 of the side plate portion 62 is in contact with the pressing portion 33, thereby limiting the side plate portion 62 from floating up from the side 28. In addition, when the retaining body 60 is assembled to the temporary stop position or moves from the temporary stop position to the formal stop position, if the retained portion 65 straddles the retaining portions 34, 35, the side plate portion 62 can be elastically deformed into a double-supported state with the connection portion with the main body 61 side and the contact portion with the pressing portion 33 as fulcrums. As the retained portion 65 passes over the retaining portions 34, 35, the side plate portion 62 quickly elastically recovers, and the retained state of the retained portion 65 and the retaining portions 34, 35 can be achieved with a sense of rhythm. When the retaining body 60 starts to be assembled to the temporary stop position or starts to move from the temporary stop position to the formal stop position, the side plate portion 62 is maintained in a cantilever state, so that the assembly resistance or movement resistance can be reduced compared with the case of the double support state.

[0047] Furthermore, in the case of the first embodiment, the locking portions 34 and 35 are composed of the temporary locking portion 35 that locks the locked portion 65 at the temporary locking position and the final locking portion 34 that locks the locked portion 65 at the final locking position. In addition, the inclined surface portion 36 is provided on both the final locking portion 34 and the temporary locking portion 35.

[0048] Therefore, when the retaining body 60 is assembled to the temporary locking position, the locked portion 65 straddles the temporary locking portion 35, and when the retaining body 60 is moved to the formal locking position, the locked portion 65 straddles the formal locking portion 34. Regardless of the state of the retaining body 60 when it is assembled or moved, the inclined surface 36 formed on the formal locking portion 34 and the temporary locking portion 35 can improve the operability and holding force of the retaining body 60.

[0049] Furthermore, the inclined surface 36 of each of the formal stopper 34 and the temporary stopper 35 has the same inclination angle relative to the surface direction of the side surface 28. Therefore, when the stopped portion 65 straddles the temporary stopper 35 and the formal stopper 34, the side plate 62 can be elastically deformed in the same manner, so that the smoothness of the bending action of the side plate 62 can be ensured. Furthermore, the mold structure for molding the inclined surface 36 does not become complicated.

[0050] [Other embodiments of the present invention] It should be considered that the above-mentioned Embodiment 1 disclosed this time is an illustration and not restrictive in all aspects. In the case of the first embodiment, the side plate portion 62 is formed to protrude forward from the left and right ends of the main body portion 61, and the stopper portions 34 and 35 are arranged in the side surface 28 of the housing 20, which is closer to the front than the retaining body mounting hole 29. In contrast, in the case of other embodiments, the side plate portion may be formed to protrude backward from the left and right ends of the main body portion, and the stopper portions may be arranged in the side surface of the housing, which is closer to the rear than the retaining body mounting hole. In the case of the first embodiment, the locked portion 65 is configured to be locked to the locking portions 34 and 35 at both the formal locking position and the temporary locking position, and the inclined portion 36 is formed on either the formal locking portion 34 or the temporary locking portion 35. In contrast, in the case of other embodiments, the locked portion may be configured to be locked to the locking portion at either the temporary locking position or the formal locking position, and the inclined portion may be formed only on either the formal locking portion or the temporary locking portion. In the case of the above-mentioned embodiment 1, when the retaining body 60 is assembled to the temporary locking position or when it moves from the temporary locking position to the formal locking position, the locked portion 65 is in full contact with the inclined surface 36 of the locking portions 34 and 35. In contrast, in the case of other embodiments, when the retaining body is assembled to the temporary locking position or when it moves from the temporary locking position to the formal locking position, the locked portion may be partially in contact with the inclined surface of the locking portion or may not be in contact with the inclined surface. According to other embodiments, the contact resistance of the locked portion relative to the locking portion can be reduced, and the elastic deformation amount of the side plate portion can be reduced, so the operability of the retaining body can be further improved.
