Description

Technical Field

[0001] The present disclosure relates to connectors. Background Art

[0002] The connector described in Patent Document 1 includes a housing for accommodating terminal parts and a stopper (integrated stopper) mounted on the housing. An assembly hole (stopper assembly opening) is formed on the lower surface of the housing. The stopper has a stopper body (stopper portion) inserted into the assembly hole to prevent the terminal parts from falling off.

[0003] The connectors described in Patent Documents 2 and 3 respectively have an assembly hole (fitting groove, groove portion) formed in the housing opened over three surfaces of the housing, namely, the lower surface and the left and right side surfaces. The housing is composed of a front portion and a rear portion respectively arranged on the front side and the rear side with the assembly hole interposed therebetween, and a connecting portion connecting the front portion and the rear portion at the assembly hole. Specifically, in Patent Document 2, Figure 1 The beam-shaped portion above the fitting groove indicated by reference numeral 13 and the Fig.10 The beam-shaped portion above the groove portion indicated by reference numeral 32a can correspond to the above-mentioned connecting portion.

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described below. The connector disclosed herein, (1) It comprises: a terminal part; a shell for accommodating the terminal part; and a stopper assembled in the shell to restrict the terminal part from coming out of the shell, the shell having an assembly hole, a front part and a rear part, wherein the assembly hole is open in three of four directions, namely, up, down, left and right, which intersect with the mating direction in which the connector is mated with the other connector, the front part and the rear part are respectively arranged at the front side and the rear side of the assembly hole separated by the mating direction, and the stopper comprises a stopper main body arranged inside the assembly hole, a front side abutting part arranged forward of the stopper main body and in contact with the front part from the front side, and a rear side abutting part arranged rearward of the stopper main body and in contact with the rear part from the rear. According to the above configuration, since the mounting hole is open in three directions of the housing, the outer wall portion for closing the left and right outer sides of the mounting hole can be omitted from the housing, and the left-right dimension (width dimension) of the housing can be reduced. In addition, when the stopper body is disposed inside the mounting hole, the front abutment portion contacts the front portion of the housing from the front side, and the rear abutment portion contacts the rear portion of the housing from the rear side, so that even if a force that causes the front portion and the rear portion to open (separate) is applied to the housing, it is possible to avoid excessive stress being applied to the connecting portion connecting the front portion and the rear portion. As a result, the strength of the housing can be ensured. Furthermore, since the stopper body, the front abutment portion and the rear abutment portion are integrally formed on the stopper, the number of components can be reduced compared to the case where a component separate from the stopper contacts the front and rear portions, thus avoiding complication of the connector structure.

[0011] (2) It is preferable that the rear portion has a contacted portion formed on left and right side surfaces thereof, the contacted portion coming into contact with the rear side contact portion. According to the above structure, compared with the situation that the abutted portion is formed in the inside of the rear portion, the shape of the abutted portion can be simplified. In addition, if the rear side abutting portion is formed in pairs on the stopper in a manner corresponding to each abutted portion, the stopper can be well-balanced and assembled on the housing.

[0012] (3) Alternatively, the stop member may form a hook-shaped hook portion when viewed from the side through the rear side abutment portion and the connection portion connecting the rear side abutment portion to the stop member main body, and the abutted portion may be formed into a convex shape that fits into a recess formed between the stop member main body and the hook portion. According to the above structure, since the hooking portion can also contact the abutted portion from the connecting portion side, the assembly posture of the stopper relative to the housing can be stabilized. In addition, by observing the connector from the side, the contact state of the hooking portion and the abutted portion can be confirmed.

[0013] (4) The rear portion may include a restriction portion, the restriction portion being disposed rearward of the contacted portion, and the rear contact portion being sandwiched between the restriction portion and the contacted portion. According to the above configuration, since the retreat of the rear-side abutting portion is restricted by the restriction portion, the state in which the rear-side abutting portion and the abutted portion are in contact can be maintained.

[0014] (5) The facing surfaces of the rear side contact portion and the contacted portion may be dovetail inclined surfaces that contact each other in a direction in which the rear side contact portion opens outwardly from the contacted portion to the left and right sides. According to the above configuration, since the expansion of the rear side contact portion to the left and right outer sides is restricted by the dovetail slope, the state in which the rear side contact portion and the contacted portion are in contact can be maintained more satisfactorily.

[0015] (6) The front contact portion may be formed by a front shielding portion that covers the front surface of the front portion. According to the above configuration, there is no need to provide a special structure on the housing as the front contact portion, and thus the connector can be prevented from being complicated.

[0016] [Details of the embodiments of the present disclosure] Hereinafter, specific examples of the present disclosure will be described with reference to the drawings. In addition, the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all changes within the meaning and scope of the claims and their equivalents.

[0017] <Implementation method 1> like Figure 3 As shown, the connector 10 of the first embodiment of the present disclosure includes a housing 11, a stopper 12 mounted on the housing 11, and a terminal part 80 accommodated in the housing 11. The housing 11 is configured to be able to be mated with a counterpart connector 90. In the following description, in terms of the front-to-back direction, the side of the housing 11 that is mated with the counterpart connector 90 is defined as the front side. Figure 3 The left side of the Figure 3 The vertical direction is based on Figure 3 The paper thickness direction is taken as the reference. The left-right direction can also be called the width direction. Figure 1 In the figure, the front-rear direction is indicated by reference symbol X, the left-right direction is indicated by reference symbol Y, and the up-down direction is indicated by reference symbol Z. The up-down direction does not necessarily coincide with the direction of gravity when the connector 10 is mounted on an installation object such as a vehicle.

[0018] (Housing and terminal parts) The housing 11 is made of synthetic resin and is generally in the shape of a square block. Figure 1 to Figure 4As shown in the appropriate position of the structure, it is formed by an upper surface 13 facing upward, a lower surface 14 facing downward, left and right side surfaces 15 facing outward in the left-right direction, a front surface 16 facing forward, and a rear surface 17 facing rearward.

[0019] like Figure 3 and Figure 4 As shown, the housing 11 has a plurality of chambers 18 that penetrate in the front-to-back direction. Each chamber 18 is arranged in the housing 11 in multiple layers (three layers in the case shown) in the up-down direction and in multiple layers in the left-right direction. The housing 11 has a lance 19 that protrudes forward from the inner lower surface of each chamber 18 and is elastically deformable.

[0020] The terminal part 80 is made of conductive metal, such as Figure 3 As shown, the front end portion has a box portion 81. The terminal part 80 is inserted into the cavity 18 from the rear and the box portion 81 is locked to the lance 19, thereby being initially prevented from coming off relative to the housing 11. In addition, the rear end portion of the terminal part 80 is crimped to the electric wire 70. The electric wire 70 is led out from the rear surface 17 of the housing 11 to the rear.

[0021] like Figure 3 As shown in FIG. 1 , the housing 11 has a locking arm 21 extending rearward from the front end of the upper surface 13. The locking arm 21 is configured to be elastically deformable in the vertical direction with the base portion 23 at the front end side as a fulcrum. The locking arm 21 is locked to a locking receiving portion 91 formed on the other side connector 90, thereby maintaining the housing 11 and the other side connector 90 in a mating state.

[0022] like Figure 4 As shown, the housing 11 has a mounting hole 24 opened in the middle of the left and right side surfaces 15 and the lower surface 14 in the front-rear direction. In other words, the mounting hole 24 is open in the middle of the housing 11 in the front-rear direction in three directions: left and right and downward.

[0023] The housing 11 has a front portion 25 disposed on the front side with the assembly hole 24 interposed therebetween and a rear portion 26 disposed on the rear side. Each chamber 18 is formed in the front portion 25 and the rear portion 26. Each lance 19 is formed in the front portion 25. Figure 3 and Figure 4 As shown, the housing 11 has a connecting portion 27 that blocks the upper end of the mounting hole 24 and extends in the front-rear direction to connect the front end to the upper end side of the front portion 25 and the rear end to the upper end side of the rear portion 26. The front portion 25 and the rear portion 26 are connected to each other only via the connecting portion 27.

[0024] like Figure 1 and Figure 4As shown, the rear portion 26 of the housing 11 has a flange portion 28 extending outward from the rear ends of the upper surface 13, the lower surface 14, and the left and right side surfaces 15. The flange portion 28 is formed to cover the rear end portion of the locking arm 21 from above and is connected to the outer periphery of the housing 11 over the entire periphery.

[0025] like Figure 4 As shown in the figure, the front part 25 of the housing 11 has: a flange part 29 extending in the left-right direction including the base end part 23 of the locking arm 21 at the upper part of the front end; and a pair of side ends 22 extending downward from the left and right ends of the flange part 29 at the front ends of the left and right side surfaces 15. The front surface 16 of the front part 25 of the housing 11 is set back from the front ends of the flange part 29 and each side end 22 to the rear.

[0026] like Figure 4 As shown in FIG. 1 , each side end portion 22 has a guide groove 31 that is opened on the opposite surface of each other and extends in the up-down direction and opens downward. In addition, each side end portion 22 has a front side retained portion 32 that is connected to the guide groove 31 and extends in the front-to-back direction and opens forward. The guide groove 31 guides the movement of the front shielding portion 43 of the stopper 12, which will be described later. When the stopper 12 reaches the formal locking position, which will be described later, the front side retained portion 32 is Figure 2 As shown, the front shielding portion 43 is locked to a front holding portion 54 described later, thereby restricting downward movement of the front shielding portion 43.

[0027] like Figure 2 and Figure 4 As shown, the left and right side surfaces 15 of the housing 11 have a stepped surface 33 that divides the connection portion 27 and the assembly hole 24 and extends in the front-to-back direction. The front end of the stepped surface 33 is closed by each side end portion 22. Figure 4 The lower portion of the side surface 15 (a portion having a holding portion 34 described later) is arranged to be recessed inward in the width direction relative to the upper portion of the side surface 15 (a portion having a front held portion 32) via the step surface 33.

[0028] like Figure 4 As shown, the left and right side surfaces 15 of the front portion 25 of the housing 11 have a pair of upper and lower retaining portions 34 ( Figure 4 Only one side is shown in the figure.) Each holding portion 34 is formed in a rib shape extending in the front-rear direction. Each holding portion 34 has a function of holding the stopper 12 to the housing 11.

[0029] like Figure 2 and Figure 4As shown, the left and right side surfaces 15 of the rear portion 26 in the housing 11 have a rear step surface 35 extending in the front-rear direction at a portion below the step surface 33, and have a mounting surface 36 that is further recessed one step inward in the width direction below the rear step surface 35. The later-described hooking portion 59 of the stopper 12 is arranged along the mounting surface 36 of the rear portion 26.

[0030] like Figure 2 and Figure 4 As shown, the left and right side surfaces 15 of the rear portion 26 in the housing 11 have an abutted portion 37 protruding from the upper front portion of the assembly surface 36 and a limiting portion 38 protruding from the lower rear portion of the assembly surface 36. The abutted portion 37 is formed in a quadrangular prism shape, and the front surface is continuous with the inner surface of the assembly hole 24 without any height difference. The upper surface of the abutted portion 37 (the surface facing upward, the surface opposite to the step surface 33) is arranged at the same height position as the above-mentioned rear step surface 35. The front end of the rear step surface 35 is blocked by the abutted portion 37. As shown Figure 7 As shown, the rear surface of the contacted portion 37 is an inverted tapered dovetail slope 39 that slopes backward from the protruding base end side (the width center side (width inner side) of the housing 11) toward the front end side.

[0031] The restriction section 38 is as follows Figure 4 As shown, the abutment portion 37 and the restriction portion 38 are formed in a quadrangular prism shape, and the rear end is integrated with the flange portion 28. The abutment portion 37 and the restriction portion 38 are arranged at intervals in the vertical direction and at intervals in the front-rear direction. Figure 2 As shown, the rear side contact portion 44 of the stopper 12 described later is arranged between the contacted portion 37 and the restricting portion 38. The contacted portion 37 is arranged so as to contact the front surface of the rear side contact portion 44 and the restricting portion 38 is arranged so as to contact the rear surface of the rear side contact portion 44.

[0032] The contacted portion 37 and the restricting portion 38 have the same protruding dimensions. The front end surfaces (front end surfaces in the width direction) of the contacted portion 37 and the restricting portion 38 in the protruding direction are formed flat along the front-rear direction and the up-down direction.

[0033] The flange portion 28 has a pair of left and right through holes 41 (in Figure 1 , Figure 4 and Figure 7 Only one is shown in the figure.) The abutted portion 37 is provided so as to be visible from the rear of the housing 11 through the through hole 41 when the housing 11 is in a single state.

[0034] (Stop) The stopper 12 is made of synthetic resin, such as Figure 5 and Figure 6As shown in FIG. 1 , the stopper 12 is integrally provided with a stopper main body 42, a front shielding portion 43 as a front side contact portion arranged forward of the stopper main body 42, and a rear side contact portion 44 arranged rearward of the stopper main body 42. The rear side contact portions 44 are formed in pairs at the left and right ends of the stopper 12. The stopper 12 is provided so as to be movable to a temporary stop position (not shown) and a formal stop position (see FIG. 1 ) relative to the housing 11. Figure 1 to Figure 3 )move.

[0035] The stopper body 42 is formed into a rectangular block shape that is long in the left-right direction. Figure 3 As shown, it can be engaged with the assembly hole 24 of the housing 11. When the stopper 12 moves from the temporary stop position to the formal stop position, the stopper body 42 is deeply engaged in the assembly hole 24. The stopper body 42 has a plurality of insertion holes 45. When the stopper 12 is in the formal stop position, each insertion hole 45 is connected to each chamber 18 of the front part 25 and the rear part 26 (except the chambers 18 of the uppermost layer) in the front-to-back direction. Figure 5 As shown, the stopper body 42 has a plurality of stopper portions 46 protruding from the inner lower surface of each insertion hole 45 and the upper surface of the stopper body 42. Each stopper portion 46 is arranged at a position corresponding to each cavity 18. When the stopper 12 is in the temporary locking position, each stopper portion 46 is arranged below each cavity 18. At this time, the terminal parts 80 can be inserted into each cavity 18 from the rear. When the stopper 12 is in the formal locking position, as shown in FIG. Figure 3 As shown, each retaining portion 46 enters each cavity 18 and is arranged to be lockable with the box portion 81 of each terminal fitting 80. The terminal fitting 80 is secondarily retained relative to the housing 11 by the retaining portion 46.

[0036] The front shielding portion 43 is formed in a plate shape and is arranged so as to cover the front surface 16 of the front portion 25 of the housing 11. The front shielding portion 43 has a plurality of protrusion passage holes 47 at positions corresponding to the respective chambers 18. Figure 3 As shown, when the housing 11 and the mating connector 90 are in a mating state, the tabs 95 of the mating terminal assembled on the mating connector 90 are inserted from the front into each tab through hole 47. The tabs 95 of the mating terminal are inserted into the box portion 81 of the terminal part 80 and are electrically connected to the terminal part 80.

[0037] like Figure 6 As shown, the front shielding portion 43 has a plurality of tool passage holes 48 at positions corresponding to the respective lances 19. The respective tool passage holes 48 and the respective tab passage holes 47 are arranged in a row along the left-right direction in the front shielding portion 43. Although not shown, when the stopper 12 is located at the temporary stop position, by inserting a tool into the respective tool passage holes 48 from the front and pulling down the lance 19 with the front end of the tool, the terminal component 80 can be pulled out from the cavity 18.

[0038] The front shielding portion 43 is as shown in Figure 5 As shown in part in FIG. 1 , the rear surface has a plurality of partitions 49 arranged at intervals in the left-right direction. Each partition 49 is formed in a manner extending in the up-down direction between each protruding piece through hole 47 in the rear surface of the front shielding portion 43. Figure 3 As shown, the partition 49 is connected to the partition wall 51 between the chambers 18 in the front portion 25 of the housing 11 in the front-rear direction. Although not shown, the tool holes 48 penetrate through the partitions 49.

[0039] The end of the front shielding portion 43 in the left and right direction is as follows Figure 5 As shown in the figure, the guide rib 53 has an end surface 52 as a plate thickness surface, and a guide rib 53 extending in the up-down direction at the rear of the end surface 52. The guide rib 53 has a front side retaining portion 54 at the upper end side. The guide rib 53 is configured to be able to fit into the guide groove 31 of the side end portion 22. Figure 2 As shown, the front holding portion 54 of the guide rib 53 is locked to the front held portion 32 of the side end portion 22 .

[0040] In addition, if Figure 6 As shown, the stopper 12 includes a pair of left and right side portions 55 connecting the stopper body portion 42 and the front shielding portion 43 , and a pair of left and right connecting portions 56 connecting the stopper body portion 42 and the rear abutting portion 44 .

[0041] Each side portion 55 is formed in a plate shape and is formed along the front-to-back direction from the left-right end of the stopper main body portion 42 toward each guide rib 53 of the front shielding portion 43. Each side portion 55 has a rib-shaped held portion 57 extending along the front-to-back direction at the upper end of the mutually opposed surface. The held portion 57 of each side portion 55 is engaged with each holding portion 34, thereby holding the stopper 12 at the temporary engaged position and the formal engaged position relative to the housing 11.

[0042] Each connection portion 56 is formed in a plate shape and is formed along the front-rear direction from the left-right end of the stopper body portion 42 toward each rear side contact portion 44. In addition, each connection portion 56 is formed along the lower end of the stopper 12.

[0043] Each rear side contact portion 44 is formed in a plate shape and is formed along the vertical direction. Each rear side contact portion 44 is connected to each connecting portion 56 in a cross manner, and each rear side contact portion 44 has a portion protruding upward from each connecting portion 56. The rear side contact portion 44 and the connecting portion 56 are continuous and integrated with each other without any height difference, forming an L-shaped hooking portion 59 when viewed from the side. Figure 5As shown, the plate thickness (left-right dimension) of the hook portion 59 is set to be larger than the plate thickness of the side portion 55. Between the rear surface of the stopper body 42, the front surface of the rear side contact portion 44 (the dovetail slope 62 described later) and the upper surface of the connecting portion 56, that is, between the stopper body 42 and the hook portion 59, a U-shaped recess 61 is formed, which is open upward and in the left-right direction when viewed from the side. Figure 2 As shown in FIG. 1 , the contacted portion 37 of the housing 11 is configured to be engageable with the recess 61. Figure 7 As shown, the front surface of the rear side contact portion 44 forms a dovetail slope 62 that slopes backward from the inner side in the width direction (the width direction center side (the inner side in the width direction) of the stopper 12 ) toward the outer side.

[0044] (Function of connector) When the stopper 12 is located at the formal locking position relative to the housing 11, as shown in FIG. Figure 3 As shown, the entirety of the stopper body 42 is fitted into the assembly hole 24 of the housing 11, and the front shielding portion 43 is arranged to face the front surface 16 of the front portion 25 of the housing 11. The partitions 49 of the front shielding portion 43 are arranged in a manner that they can contact the front end surfaces of the partitions 51 in the front surface 16 of the front portion 25.

[0045] like Figure 1 and Figure 2 As shown in FIG. 1 , each side portion 55 is arranged below the step surface 33 in the left and right side surfaces 15 of the front portion 25. Each hook portion 59 is arranged facing the mounting surface 36 at a position below the rear step surface 35 in the left and right side surfaces 15 of the rear portion 26. Overall, the left and right end surfaces of the stopper 12 are arranged on the upper side surface ( Figure 1 The outer surface of the side end portion 22 of the upper side is at the same position in the width direction or at a position retracted inwardly in the width direction than the upper side.

[0046] The rear side contact portion 44 of each hook portion 59 is inserted from below and sandwiched between the contacted portion 37 and the restricting portion 38 on the left and right side surfaces 15 of the rear portion 26. Figure 7 As shown, the dovetail slopes 39 and 62 of the rear contact portion 44 and the contacted portion 37 are arranged to face each other. The contacted portion 37 is arranged to overlap the rear contact portion 44 from the outer side in the width direction on the dovetail slope 39 .

[0047] When the connector 10 is mounted on a vehicle or other installation object (not shown), when the wires 70 led out from the rear portion 26 of the housing 11 vibrate in the vertical direction or are pulled up, an external force may be applied to the housing 11 through the connecting portion 27 to open (separate) the front portion 25 and the rear portion 26 (see, for example, Figure 2 , Figure 3Arrow F in the figure).

[0048] In contrast, in the case of the first embodiment, when the external force acts, Figure 2 As shown, the partition portion 49 of the front shielding portion 43 can contact the front surface 16 of the front portion 25 (the front end surface of the partition wall 51) from the front, and the rear abutting portion 44 can contact the abutted portion 37 of the rear portion 26 from the rear. In addition, the stopper 12 is retained on the housing 11 by the locking action of the front holding portion 54 and the front held portion 32 and the locking action of the holding portion 34 and the held portion 57. In the case where the connector 10 does not have the rear abutting portion 44 and the abutted portion 37 as in the first embodiment, the rear portion 26 is opened away from the front portion 25 by the upward external force (at this time, the cover portion 96 of the other connector 90 (see FIG. 1 ) is also opened). Figure 3 ) is opened), the front-to-rear width of the assembly hole 24 is expanded, and the connecting portion 27 is bent and deformed. In the worst case, the connecting portion 27 may be broken. In contrast, in the case of the first embodiment, as described above, the rear side abutment portion 44 and the abutted portion 37 are formed in the connector 10, and the stopper 12 fastens the front portion 25 and the rear portion 26. Therefore, it is possible to prevent the front portion 25 and the rear portion 26 from opening apart with the connection portion 27 sandwiched therebetween, and it is possible to avoid excessive stress being applied to the connection portion 27. As a result, the connector 10 can ensure the strength of the housing 11.

[0049] In the case of the first embodiment in particular, the dovetail slopes 39 and 62 of the rear abutting portion 44 and the abutted portion 37 are in contact with each other, so that the rear abutting portion 44 is difficult to open in the direction away from the mounting surface 36. That is, since the rear side portion of the stopper 12 is firmly locked to the rear portion 26, it is possible to more reliably suppress the rear portion 26 from opening in a manner away from the front portion 25. In addition, the rear surface of the rear abutting portion 44 is in contact with the restricting portion 38, so that the rear abutting portion 44 can be suppressed from being displaced in the rear direction. In addition, by engaging the abutted portion 37 in the recess 61 formed between the stopper main body 42 and the hook portion 59, in addition to enabling the rear side abutting portion 44 of the hook portion 59 to contact the rear surface (dovetail slope 39) of the abutted portion 37, the connecting portion 56 of the hook portion 59 can also contact the lower surface of the abutted portion 37, thereby achieving a structure in which the rear side abutting portion 44 is difficult to tilt relative to the abutted portion 37. As a result, the state in which the rear side abutting portion 44 and the abutted portion 37 are in contact can be maintained, and the front portion 25 and the rear portion 26 can be more effectively suppressed from opening apart from each other.

[0050] <Implementation method 2> In the case of Embodiment 2 of the present disclosure, if Figure 8 to Figure 10As shown in FIG. 1 , the stopper 12 has a structure that is locked to the flange portion 28 of the housing 11 , which is different from the first embodiment described above.

[0051] The housing 11 does not have a protruding portion disposed on the mounting surface 36 (see Fig.10 ) is not a limiting portion 38, but a recessed portion 65 is formed between the abutted portion 37 and the flange portion 28 to sandwich the rear abutting portion 44A. Fig. 9 As shown, the front-to-back width (plate width in the front-to-back direction) of the rear side abutment portion 44A is set to be larger than the top-to-bottom width (plate width in the top-to-bottom direction) of the connecting portion 56, and is equal to the front-to-back width ( Fig. 9 The distance between the abutted portion 37 and the flange portion 28 in the front-to-rear direction corresponds to the separation distance).

[0052] The front surface of the rear side contact portion 44A is formed into a dovetail slope 62A (details not shown) that contacts the dovetail slope 39 of the contacted portion 37, similarly to the first embodiment. Fig.10 As shown, the rear surface of the rear side contact portion 44A has a lower portion in contact with the front surface of the flange portion 28 and an upper portion facing the through hole 41 of the flange portion 28. In the case of the second embodiment, the flange portion 28 functions as a restricting portion.

[0053] The stopper 12 has a locking portion 63 protruding from the upper portion of the rear surface of each rear side abutment portion 44A. Fig.10 As shown, the locking portion 63 is formed in a rib shape extending in the up-down direction at the left-right center portion of the rear surface of the rear side abutment portion 44A.

[0054] When the stopper 12 is located at the formal locking position relative to the housing 11, the rear abutting portion 44A is fitted into the recess 65 between the abutted portion 37 and the flange portion 28, and the locking portion 63 elastically enters the interior of the through hole 41 and contacts the inner lower surface of the through hole 41. In this way, the locking portion 63 of each rear abutting portion 44A contacts the inner lower surface of each through hole 41, thereby restricting the displacement of each rear abutting portion 44A in the direction of separation from the housing 11, that is, downward.

[0055] According to the second embodiment, the stopper 12 is locked to the front portion 25 of the housing 11 by the locking action between the front holding portion 54 and the front held portion 32 and the locking action between the holding portion 34 and the held portion 57, and is also locked to the rear portion 26 of the housing 11 by the locking action between the locking portion 63 and the flange portion 28. As a result, the stopper 12 is held by the front portion 25 and the rear portion 26 of the housing 11 so as to be well balanced in the front-rear direction.

[0056] [Other embodiments of the present disclosure] The above-described first embodiment disclosed this time should be considered in all respects as illustrative and non-restrictive. In the case of the first embodiment, the stopper has the front shielding portion as the front contact portion. In contrast, according to other embodiments, the stopper may have a dedicated portion that contacts the front portion of the housing from the front instead of the front shielding portion as the front contact portion. In the case of the above-mentioned embodiment 1, dovetail slopes are formed on both the rear abutting portion and the abutted portion. In contrast, according to other embodiments, a dovetail slope may be formed on only one of the rear abutting portion and the abutted portion. Alternatively, the rear abutting portion and the abutted portion may not have dovetail slopes, and may only have surfaces that contact along the left-right direction. In the case of the first embodiment, the contacted portion that contacts the rear contact portion is formed on the left and right side surfaces of the rear portion. In contrast, according to other embodiments, the contacted portion that contacts the rear contact portion may be formed inside the rear portion. In the case of the above-mentioned embodiment 1, the housing is formed into a polygonal cross section. In contrast, according to other embodiments, the housing may also be formed into a circular cross section. In the present disclosure, when the housing is formed into a circular cross section, it is also preferred that the assembly hole is open in three of the four directions of the upper, lower, left, and right directions in the housing.
