Description

TECHNICAL FIELD

[0001] The present disclosure relates to a connector. BACKGROUND

[0002] The connector disclosed in Patent Literature 1 has a female housing and a male housing that can be fitted to each other, and a detection member that is assembled to the female housing. The female housing has a lock lever (lock arm) that can be elastically deformed to hold the two housings in a fitted state. The female housing has a mounting groove that accommodates the detection member on the lower side (displacement space side) of the lock lever. The detection member is configured to be movable with respect to the female housing from a standby position to an access position. If the detection member is movable to the access position, it is detected that the lock lever is elastically returned from the displacement space and is locked, that is, it is detected that the two housings are properly fitted.

[0003] The connector disclosed in Patent Literature 2 has a lever that is rotatably provided in a female connector housing. A lock arm is provided in the lever. In the connector structure disclosed in Patent Literature 2, a member corresponding to the above-described detection member can also be provided.

[0007] Patent Literature 2: Japanese Patent Application Publication No. 2015-88274 SUMMARY

[0008] PROBLEMS TO BE SOLVED BY THE INVENTION

[0009] In the case of Patent Literature 1, since the mounting groove that accommodates the detection member is provided on the lower side of the lock lever, there is a concern that the connector becomes large in the up-down direction. In addition, in the case of Patent Literature 1, the handle portion is to be held when moving the detection member, and this handle portion protrudes to the rear of the female housing. Therefore, there is also a concern that the connector becomes large in the front-rear direction (fitting direction).

[0010] Therefore, an object of the present disclosure is to provide a connector that can avoid the large size caused by the presence of a detection member.

[0011] MEANS FOR SOLVING THE PROBLEMS

[0012] The connector of the present disclosure has a housing, a lock arm that holds the housing and an opposite-side housing in a fitted state, and a detection member that becomes a state in which it is movable with respect to the lock arm at the time of proper fitting of the housing and the opposite-side housing, the detection member being disposed on one side surface side of the lock arm.

[0013] EFFECT OF THE INVENTION

[0014] According to the present disclosure, a connector that can avoid upsizing caused by the presence of a detection member can be provided. BRIEF DESCRIPTION OF DRAWINGS

[0034] [Explanation of Embodiments of the Present Disclosure]

[0035] First, an embodiment of the present disclosure is explained.

[0036] (1) The connector of the present disclosure has: a housing; a locking arm that holds the housing and an opposite-side housing in a fitted state; and a detection member that becomes a state in which it is movable with respect to the locking arm at the time of correct fitting of the housing and the opposite-side housing, the detection member being arranged on one side surface side of the locking arm. According to this structure, since the detection member is arranged on one side surface side of the locking arm, the connector can be prevented from becoming large in the length direction and the flexing direction of the locking arm.

[0037] (2) It is preferable that the detection member become a state in which it is movable from the one side surface side to the other side surface side of the locking arm at the time of correct fitting of the housing and the opposite-side housing. According to this structure, the detection member can be moved to the other side surface side of the locking arm, and thus it is possible to detect that the two housings are correctly fitted.

[0038] (3) A protection wall is arranged on the side of the one side surface of the locking arm, the protection wall having a mounting portion that movably holds the detection member. According to this structure, the protection wall can have both a protection function that protects the locking arm from the side and a holding function that holds the detection member. Thus, compared to a case in which the portion having the protection function and the holding function are separately provided, it is possible to simplify the configuration of the connector. In addition, it is possible to further suppress the large size of the connector.

[0039] (4) The connector has a lever that advances the fitting of the housing and the opposite-side housing, the locking arm being provided to the lever, and the detection member being held to the lever. According to this structure, it is possible to simplify the configuration of the housing.

[0040] (5) The rod has a frame portion covering the locking arm, which rotates in the fitting direction when the outer shell and the opposing outer shell are engaged. The frame portion has a rod pressing surface protruding rearward in the fitting direction within the rod. The detection member has a flat base portion that can move relative to the locking arm in the detection direction when the outer shell and the opposing outer shell are properly engaged. The base portion has a detection member pressing surface protruding rearward in the detection direction within the detection member. The rod pressing surface and the detection member pressing surface face different directions from each other. With this structure, when the rod is rotated in the fitting direction, the rod pressing surface can be pressed without contacting the detection member pressing surface. Furthermore, when the detection member is moved in the detection direction, the detection member pressing surface can be pressed without contacting the rod pressing surface. Therefore, the rotation of the rod and the movement of the detection member can be performed without interference.

[0041] [Details of the embodiments disclosed]

[0042] Specific examples of the connectors disclosed herein will be described below with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples and is intended to include all modifications shown by way of the claims and within the scope and meaning of their equivalents.

[0043] like Figure 2 As shown, the connector of this embodiment includes a connector body 10, a rod 11, a detection member 12, and a terminal part 13. The connector body 10 can be fitted with the opposite-side housing 14. The connector body 10 has a housing 15, a cover 16, a front retainer 17, and a stop 18. The connector body 10 is the part that houses and holds the terminal part 13 and the wire 24 connected to the terminal part 13. In the following description, regarding the front-back direction, the side facing each other when the connector body 10 and the opposite-side housing 14 begin to fit together is referred to as the front side. Regarding the vertical direction, ... Figures 1-3 The vertical direction of each diagram is used as the reference. The directions specified in this specification do not necessarily have to be consistent with the actual directions.

[0044] <Opponent's side shell>

[0045] The outer casing 14 on the opposite side is made of synthetic resin, such as Figure 2 As shown, the device has a cylindrical cover 19. Multiple tab-shaped male terminal parts 20 are protruding from the cover 19. A cylindrical cam follower 21 protrudes from the inner surface of the upper wall of the cover 19. The opposite outer housing 14 is fixed to a circuit board (not shown). The rear portion of the male terminal parts 20 is connected to a conductive portion of the circuit board on the outer side of the cover 19.

[0046] <Housing, terminal parts, stop body, front retainer>

[0047] The housing 15 is made of synthetic resin and has a square block shape as shown in Figure 2 and Figure 3 is fitted in the cover portion 19. The housing 15 has a plurality of cavities 22 in the interior. Each cavity 22 is formed in the housing 15 so as to extend through in the front-rear direction. The housing 15 has a lance portion 23 protruding forward on the inner wall of each cavity 22.

[0048] The terminal member 13 is inserted into each cavity 22 of the housing 15 from the rear. The terminal member 13 is once caught by the lance portion 23 in the cavity 22.

[0049] The terminal member 13 is a female terminal member and is formed by bending processing or the like of a conductive metal plate. The front portion of the male terminal member 20 is inserted into the box-shaped portion on the front side of the terminal member 13 to be connected when the connector main body 10 and the counterpart housing 14 are fitted. The terminal member 13 is electrically and mechanically connected to the terminal portion of the electric wire 24.

[0050] The housing 15 has a stopper mounting hole 25 extending in the up-down direction and opening to the lower surface. The stopper mounting hole 25 communicates with each cavity 22. The stopper 18 is inserted from below in the stopper mounting hole 25 of the housing 15. The terminal member 13 is twice caught by the stopper 18 to be reliably fixed in the housing 15.

[0051] The front retainer 17 is mounted to the housing 15. The front retainer 17 has a front wall portion covering the front surface of the housing 15. The front wall portion of the front retainer 17 has a plurality of male terminal insertion holes 26 at positions communicating with each cavity 22. The male terminal member 20 is inserted through the male terminal insertion hole 26 to be connected to the terminal member 13.

[0052] The housing 15 has a rod housing chamber 27 at the upper end portion above the formation region of each cavity 22 and the mounting region of the front retainer 17. As shown in Figure 4 , the rod housing chamber 27 has a flat pocket shape in the width direction and opens to the rear surface of the housing 15.

[0053] The housing 15 has an upper wall portion 28 partitioning the upper surface of the rod housing chamber 27. As shown in Figure 1 , the upper wall portion 28 has a cam follower insertion slot 29 extending in the front-rear direction and opening to the front surface of the housing 15 at the width direction central portion. The cam follower 21 of the counterpart housing 14 is inserted into the cam follower insertion slot 29. Further, the upper wall portion 28 has an arm retreat portion 30 recessed in a concave shape at the rear end edge of the width direction one side (right side). The lock arm 31 described later retreats inside the arm retreat portion 30 (see Figure 1 ). Figure 14

[0054] As shown in​Figure 4 As shown, the housing 15 has a cylindrical shaft portion 32 protruding from the center of the lower surface of the rod storage chamber 27 in the width direction. The shaft portion 32 rotatably supports the rod 11. In addition, the housing 15 has a claw-shaped locking portion 33 protruding from one side of the lower surface of the rod storage chamber 27 in the width direction. The locking portion 33 has a smaller protrusion dimension than the shaft portion 32. The locking portion 33 is positioned at the rear end of the rod storage chamber 27, facing the arm retraction portion 30.

[0055] like Figure 4 As shown, the housing 15 has upper and lower track portions 34 on its rear surface, extending along its width. The upper track portion 34 is positioned below the rod storage chamber 27. The lower track portion 34 is positioned at the lower end of the housing 15. The areas forming the cavities 22 are located between the two track portions 34. The two track portions 34 form a slit-like structure extending across the entire width of the housing 15. The two track portions 34 have engagement portions 35 at multiple points along their extension direction. Figure 2 As shown, when viewed from the extending direction of the track section 34, the meshing section 35 forms an L-shaped cross section.

[0056] In addition, such as Figure 4 As shown, the two track portions 34 have groove-shaped locking receiving portions 36 on the inner sides of both ends in the width direction (extension direction). The cover 16 is slidably mounted on the housing 15 along the two track portions 34, the sliding movement is restricted by the locking receiving portions 36, and disengagement from the track portions 34 is restricted by the engaging portions 35.

[0057] like Figure 1 and Figure 4 As shown, the outer casing 15 has a pair of upper and lower notches 37 at the four corners of its rear surface. Each notch 37 is positioned close to the locking receiving portion 36 of each of the two track portions 34. The upper notches 37 are configured to communicate with the rod storage chamber 27. Each notch 37 opens rearward and to the side, and has a stop portion 38 along the vertical direction on its inner side. The stop portion 38 stops the sliding movement of the cover 16.

[0058] <cover>

[0059] The cap 16 is made of synthetic resin, such as Figure 5 and Figure 6 As shown, it forms a hat shape as a whole. Figure 2 As shown, the cover 16 is fitted onto the housing 15 and surrounds a plurality of wires 24 extending from the rear surface of the housing 15. The cover 16 has: a back wall 39, which is disposed opposite to the rear surface of the housing 15 when fitted onto the housing 15; and a pair of opposing walls 40, 41, which protrude forward from the upper and lower ends of the back wall 39. The two opposing walls 40, 41 are disposed parallel to each other.

[0060] The cover 16 has a space on the inside for storing the wires 24, opening forward and to the side (obliquely). For example... Figure 5 As shown, the front opening of the cover 16 serves as a wire inlet 42 for guiding the wire 24 into the space. The upper and lower ends of the wire inlet 42 are separated by the front ends of two opposing walls 40 and 41. The side opening of the cover 16 serves as a wire outlet 43 for guiding the wire 24 to the outside. The wire outlet 43 is separated at the rear of the cover 16 by a outlet tube 44.

[0061] The outlet tube 44 has a wall portion along the width direction connected to two opposing walls 40, 41 and a wall portion along the vertical direction connected to the back wall 39, forming a shape that protrudes in a direction inclined relative to the front-rear direction. For example... Figure 18 As shown, each wire 24 is secured to the outlet tube 44 by fastening unit 45 such as a strap.

[0062] like Figure 6 As shown, the cover 16 has a blocking portion 46 at one end in the width direction on the side opposite to the wire outlet 43. The blocking portion 46 is a wall connected to the back wall 39 in the vertical direction. In addition, the blocking portion 46 is arranged in the front-back direction. The upper and lower ends of the blocking portion 46 are connected to two opposing walls 40, 41.

[0063] like Figure 5 As shown, the two opposing walls 40 and 41 have upper and lower guide portions 47 at their front ends, extending along the width direction. The two guide portions 47 are formed on the inner surfaces of the two opposing walls 40 and 41 over their entire width. Figure 2 As shown, the track section 47 forms a concave-convex shape on the inner surfaces of the two opposing walls 40 and 41, which can engage with the engagement section 35 of the outer casing 15.

[0064] like Figure 5 As shown, each of the two track portions 47 has a locking portion 48 at one end in the width direction. The locking portion 48 is flexibly deformable and cuts into the track portion 47. The locking portion 48 has a locking protrusion 49 protruding forward toward the opposing walls 40, 41.

[0065] With the two track portions 47 inserted into the two track portions 34 and engaged with the engagement portion 35, the cover 16 slides relative to the outer casing 15. As the cover 16 is about to be correctly installed onto the outer casing 15, the locking protrusion 49 rests against the inside of the track portion 34, causing the locking portion 48 to flex and deform. When the cover 16 is correctly installed onto the outer casing 15, the locking portion 48 elastically returns to its original position, and the locking protrusion 49 engages with the locking receiving portion 36, maintaining the state where the movement of the cover 16 relative to the outer casing 15 is restricted.

[0066] like Figure 5 and Figure 7As shown, the two opposing walls 40, 41 have guide portions 50 extending in the width direction on their outer surfaces. Figure 12 and Figure 14 As shown, the guide portion 50 is configured to abut against the opening end of the track portion 34 in the rear surface of the housing 15 when the cover 16 is assembled to the housing 15. Additionally, as... Figure 5 As shown, the two opposing walls 40 and 41 have a stop portion 51 on their outer surfaces. The stop portion 51 is formed in the shape of a rectangular plate and is connected to one end of the guide portion 50 in the width direction, and is disposed at one end of the opposing walls 40 and 41 in the width direction. When the cover 16 is correctly installed onto the housing 15, the stop portion 51 is inserted into the corresponding notch portion 37 and touches the stop portion 38, and the sliding movement of the cover 16 is stopped. The stop portion 38 is disposed on the outer side of the top end side of the locking portion 48.

[0067] like Figure 7 As shown, the two opposing walls 40 and 41 have ribs 52 and 53 extending in the width direction protruding from their outer surfaces at positions rearward of the guide portion 50. For example... Figure 5 As shown, a rib (hereinafter referred to as the first rib 52) of one of the two opposing walls 40 and 41 has one end (one end in the extending direction and one end in the width direction) at a distance from the blocking portion 46, and the other end (the other end in the extending direction and the other end in the width direction) at a position connected to the wire outlet 43. Figure 6 As shown, the rib (hereinafter referred to as the second rib 53) of the other opposing wall 41 among the two opposing walls 40 and 41 has one end connected to the blocking part 46 and the other end separated from the wire outlet 43.

[0068] Additionally, the two opposing walls 40 and 41 have movement limiting portions 54 and 55 on their outer surfaces. The movement limiting portions 54 and 55 are formed on the rear end edges (rear end faces) of the ribs 52 and 53. The movement limiting portions 54 and 55 limit the movement of the detection member 12 to the detection position described later. Figure 18 and Figure 19 As shown, the movement limiting parts 54 and 55 are arranged in an arc shape concentric with the rotation direction of the rod 11 centered on the shaft 32. Specifically, the movement limiting parts 54 and 55 are composed of a first movement limiting part 54 formed on one side of the width direction of the rear end edge of the first rib 52 and a second movement limiting part 55 formed on the other side of the width direction of the rear end edge of the second rib 53.

[0069] One end of the first movement restriction part 54 (one end in the extending direction and one end in the width direction) coincides with one end of the first rib 52 and is positioned at a distance from the blocking part 46. Figure 5As shown, on the outer surface side of the opposing wall 40, a movement path (hereinafter referred to as the first movement path 56) is formed between one end of the first movement restriction portion 54 and the blocking portion 46 for moving the detection member 12 to the detection position described later. The other end of the second movement restriction portion 55 (the other end in the extension direction and the other end in the width direction) coincides with the other end of the second rib 53 and is located at a distance from the wire outlet 43. Figure 6 As shown, on the outer surface side of the other opposing wall 41, between the other end of the second movement restriction part 55 and the wire outlet 43, a movement path (hereinafter referred to as the second movement path 57) is formed for moving the detection member 12 to the detection position.

[0070] like Figure 7 As shown, the first movement limiting part 54 and the second movement limiting part 55 are positioned so that they are at the center of the cover 16 in the case of the rearview cover 16 (see [reference]). Figure 7 The symbol A) is a point-symmetric shape centered on the center. That is, it is configured such that when the cover 16 is rotated 180° with the rearward center as the center, the arc shapes of the first movement restriction part 54 and the second movement restriction part 55 are consistent and overlap. Similarly, the first rib 52 and the second rib 53 are also point-symmetric shapes centered with the rearward center of the cover 16.

[0071] In addition, such as Figure 7 As shown, the cover 16 has a recess 58 that opens to the base end of the rear end edge of the ribs 52 and 53 (the base end of the ribs 52 and 53 in the protruding direction). The movement limiting parts 54 and 55 are provided in the region outside the opening of the recess 58 in the rear end edge of the ribs 52 and 53.

[0072] The cover 16 has pressing portions 60 and 61 on the inner side of the recess 58 in the rear end edge of the ribs 52 and 53. The pressing portions 60 and 61 are adjacent to the movement limiting portions 54 and 55 on the inner side of the recess 58 and are arranged facing the outer wall of the main body portion of the opposing walls 40 and 41. Figure 3 As shown, the pressing parts 60 and 61 are composed of a first pressing part 60 that is orthogonal to the first movement restriction part 54 on the outer surface side of an opposing wall 40 and a second pressing part 61 that is orthogonal to the second movement restriction part 55 on the outer surface side of another opposing wall 41.

[0073] <pole>

[0074] Rod 11 is made of synthetic resin, such as Figure 8 As shown, it forms a flat plate as a whole. Figure 18 As shown, the rod 11 has a bearing portion 62 with a bottom hole that is circular and a cam groove 63 extending from the vicinity of the bearing portion 62 to the outer periphery.

[0075] With the plate surface aligned along its width, the rod 11 is housed in the rod storage chamber 27 of the housing 15. Furthermore, relative to the connector body 10, the rod 11 is positioned in a temporary locking position, centered on the shaft portion 32 embedded in the bearing portion 62 (see [link]). Figure 2 , Figure 12 as well as Figure 13 ) and the official stopping position (see Figure 1 , Figure 3 as well as Figures 15-19 Rotation and displacement. When rod 11 is in the temporary locking position, the inlet of cam groove 63 is positioned facing forward. The inlet of cam groove 63 communicates with cam follower insertion groove 29, causing cam follower 21 to enter the inner side when connector body 10 and the opposite side housing 14 begin to engage.

[0076] As lever 11 rotates towards the final locking position, cam follower 21 slides on the groove surface of cam groove 63, engaging the connector body 10 with the counterpart housing 14. When lever 11 reaches the final locking position, the entrance of cam groove 63 faces the opposite side in the width direction, and cam follower 21 is positioned on the inner end side of cam groove 63. Thus, the connector body 10 and the counterpart housing 14 are correctly engaged. Furthermore, in the following structural description of lever 11, the front-back direction, vertical direction, and width direction are based on the front-back direction, vertical direction, and width direction when lever 11 is in the final locking position.

[0077] like Figure 8 As shown, the outer periphery of the rod 11 on the other end in the width direction has a temporary locking tab 64 extending rearward in a cantilever shape. The temporary locking tab 64 connects to the temporary locking receiving portion 59 within the rod receiving chamber 27 (see...). Figure 18 The lever 11 is stopped, thereby restricting its movement from the temporary stop position to the permanent stop position.

[0078] like Figure 8 As shown, the lever 11 has a locking arm 31 extending rearward in a cantilever shape from near the inner end of the cam groove 63 on one end side in the width direction. The locking arm 31 is formed in a plate shape between a pair of cut-in portions 65 in the width direction within the lever 11. The locking arm 31 is capable of flexing and deforming the front end position of the lever 11 in the vertical direction as a fulcrum.

[0079] The locking arm 31 has a rear end at a position higher than the front. For example... Figure 15 As shown, an inclined portion 67, tilted relative to the front-rear direction, is provided between the rear end and the front end of the locking arm 31. Below the rear end of the locking arm 31, the lever 11 has a mounting portion 66 that bridges the insertion portion 65 (see [reference]). Figure 12 The rear end of the locking arm 31 contacts the mounting part 66, thereby restricting the downward flexing motion of the locking arm 31.

[0080] like Figure 14 and Figure 15 As shown, the locking arm 31 has a claw-shaped locking protrusion 68 on the lower front surface near the inclined portion 67. The locking protrusion 68 can engage with the locking portion 33 of the housing 15. With the locking protrusion 68 engaged with the locking portion 33, the rod 11 is held in the properly locked position relative to the housing 15, thereby keeping the connector body 10 and the opposite housing 14 in a mating state.

[0081] like Figure 8 As shown, the rod 11 has protective walls 70 and 71, which are formed to stand upright at the opening edges of the two cut-in portions 65 and are positioned opposite the two side faces (end faces on both sides in the width direction) of the rear end of the locking arm 31 with a gap between them. The front-to-back length (including the front-to-back length of the mounting portion 73 described later) of the protective wall on one side in the width direction is greater than the front-to-back length of the protective wall on the other side in the width direction (hereinafter referred to as the second protective wall 71).

[0082] The first protective wall 70 has a portion located at one end of the rod 11 in the width direction and protruding laterally. The first protective wall 70 has a square block-shaped stop 72 protruding forward. (As shown...) Figure 1 and Figure 18 As shown, when the lever 11 reaches the final locking position, the stop 72 engages with the edge of the upper wall 28 that is continuous with the arm retraction part 30 at the rear end edge, thus stopping the rotation of the lever 11. Figure 12 As shown, the rear end face of the first protective wall 70 is flat in both the width and height directions, and its width is wider than that of the rear end face of the second protective wall 71.

[0083] like Figure 8 As shown, the first protective wall 70 has a mounting portion 73. A detection component 12 is mounted on the mounting portion 73. The mounting portion 73 has: a recessed portion 74 recessed on the outer surface of the first protective wall 70; a wall portion 75 that closes the lower inner part of the recessed portion 74; and an opening portion 76 opening into the upper inner part of the recessed portion 74. The mounting portion 73 is shaped such that it penetrates the first protective wall 70 in the width direction (wall thickness direction) through the opening portion 76 at its upper part. The recessed portion 74 has a groove portion that penetrates in the width direction and communicates with the opening portion 76 at the upper and lower positions of the front and rear inner wall surfaces.

[0084] The rod 11 has a top wall 77 along its width direction connecting the upper end of the first protective wall 70 to the upper end of the second protective wall 71. The front-to-back dimensions of the top wall 77 gradually decrease from the side of the first protective wall 70 toward the side of the second protective wall 71. The rear end face of the top wall 77 is inclined relative to the width direction when viewed from above. Figure 12As shown, the rear end faces of the top wall 77 and the first protective wall 70 become flat rod pressing surfaces 78, which are pressed when the rod 11 is moved to the final locking position.

[0085] Furthermore, between the edges of the cut-in portion 65 at the rear end of the rod 11 on one end side in the width direction, a frame portion 79 is formed by the first protective wall 70, the second protective wall 71, and the top wall 77, forming a door-shaped frame.

[0086] Additionally, rod 11 has a locking portion 80 on the inner side of top wall 77 and on the lower surface of first protective wall 70 (see...). Figure 13 , Figure 16 as well as Figure 17 The locking part 80 can be locked onto the elastic locking part 81 described later in the detection component 12.

[0087] <Detection Components>

[0088] The detection component 12 is made of synthetic resin and, while being held in the mounting portion 73 of the first protective wall 70, can be moved relative to the rod 11 to a standby position (see [reference]). Figure 2 , Figure 12 as well as Figure 16 ) and detection location (see Figure 1 , Figures 17-19 The standby position is the position in which the detection component 12 is held relative to the lever 11 before the outer casing 15 and the opposing outer casing 14 are properly engaged. The detection position is the position in which the detection component 12 moves relative to the lever 11 (locking arm 31) when the outer casing 15 and the opposing outer casing 14 are properly engaged. Furthermore, the detection direction, described later, is the direction in which the detection component 12 moves relative to the lever 11 (locking arm 31) when the outer casing 15 and the opposing outer casing 14 are properly engaged. Additionally, in the following structural description of the detection component 12, the front-back direction, vertical direction, and width direction are based on the front-back direction, vertical direction, and width direction of the detection component 12 held in the mounting portion 73 of the first protective wall 70, with the lever 11 in the fully engaged position.

[0089] like Figures 9-11 As shown, the detection component 12 has a flat base 82 at one end in the width direction. Figure 1 As shown, the end face of the base 82 on one side in the width direction becomes a pressing surface 83 of the detection component that is flat along the front-back direction and the up-down direction. Figure 9 As shown, the detection component 12 has a detection piece 84 that protrudes from the upper part of the base 82 to the other side in the width direction. The other end face of the detection piece 84 in the width direction becomes a limiting surface 85 that is flat along the vertical and horizontal directions.

[0090] The detection piece 84 has rib-like portions 86 that extend forward and backward from the prismatic main body portion and extend in the width direction. For example...Figure 15 As shown, the rib-shaped portion 86 is embedded into the groove portion of the opening 76. Additionally, as... Figure 9 and Figure 10 As shown, the detection piece 84 has an upper elastic locking portion 81 that bridges the top end of its upper surface with the front surface of the base 82. The elastic locking portion 81 is configured as a double-support beam, using the front end connected to the aforementioned prismatic main body and the rear end connected to the base 82 as fulcrums, allowing it to flex and deform in the vertical direction. The elastic locking portion 81 has upwardly protruding portions at its other end in the width direction and at its middle portion in the width direction, respectively.

[0091] The detection component 12 has a locking tab 87 that protrudes from the lower part of the base 82 to the other side in the width direction. For example... Figure 9 As shown, the locking piece 87 has a slit portion along the width direction at the rear end of the plate-shaped main body, and an elastic locking portion 81 on the lower side of the slit portion. The elastic locking portion 81 is configured as a double-support beam, enabling the slit portion to flex and deform in the direction of front-to-back width narrowing (front-to-back direction). The elastic locking portion 81 has rearwardly protruding portions at its other end in the width direction and at its middle portion in the width direction, respectively. Figure 16 As shown, the upper and lower elastic locking parts 81 are elastically locked onto the upper and lower locked parts 80 respectively, thereby keeping the detection component 12 fixed in a temporary locking position relative to the rod 11.

[0092] like Figure 9 As shown, the engaging piece 87 has a movable limiting portion 88 with a chamfered corner on the other end face (the face on the detection position side) in the width direction of the aforementioned plate-shaped main body portion. (See diagram below.) Figure 13 As shown, during the rotation of the rod 11, the movable limiting part 88 of the engaging piece 87 can slide and contact the movable limiting parts 54 and 55.

[0093] like Figure 9 and Figure 10 As shown, the snap-fit ​​piece 87 has a bent portion that first protrudes downward from the top of the aforementioned plate-shaped main body and then protrudes to the other side in the width direction. The upper surface of the protrusion 89 in the bent portion (facing the side opposite to the side opposite to the outer surface of the connector body 10 (the outer surfaces of the two opposing walls 40, 41 of the cover 16)) has a pressing portion 90. As... Figure 12 As shown, the protrusion 89 of the engaging tab 87 can fit into the recess 58. (As indicated...) Figure 12 and Figure 14 As shown, the pressed portion 90 of the protrusion 89 is positioned opposite the pressing portions 60 and 61 in a manner that allows them to abut against each other. When the pressed portion 90 contacts the pressing portions 60 and 61, it prevents the detection member 12 from shifting in a direction that separates it from the outer surfaces of the opposing walls 40 and 41.

[0094] like Figures 9-11 As shown, the detection member 12 has a connecting portion 91 at the midpoint in the vertical direction between the detection piece 84 and the engaging piece 87. The base ends of the detection piece 84 and the engaging piece 87 are connected via the connecting portion 91. The other end face in the width direction and the front and rear end faces of the connecting portion 91 are formed flatly in the vertical direction. Furthermore, the detection member 12 has a guide rib 92 that connects to the front and rear end faces of the connecting portion 91 and extends from the base 82 to the other side in the width direction. The top end of the guide rib 92 protrudes to the other side in the width direction than the other end face in the width direction of the connecting portion 91. Figure 15 As shown, the top end of the guide rib 92 is embedded in the groove on the lower side of the mounting part 73.

[0095] <Connector assembly and mating structure>

[0096] During assembly, the detection component 12 is inserted from the side into the mounting portion 73 of the first protective wall 70, located on one side of the locking arm 31, i.e., on the width side. For example... Figure 13 and Figure 16 As shown, by elastically inserting each locked portion 80 between the protrusions of each elastic locking portion 81, the detection component 12 is held in a temporary locked position relative to the rod 11.

[0097] When the detection component 12 is in the standby position, the top end (the other end in the width direction) of the detection piece 84 is positioned into the opening 76. For example... Figure 12 As shown, the limiting surface 85 of the detection piece 84 protrudes towards the inner side of the first protective wall 70 in the standby position and faces the flexural space 69 of the locking arm 31, but is not positioned to interfere with the locking arm 31. Furthermore, when the detection member 12 is in the standby position, the rib-shaped portion 86 and the guide rib 92 are inserted into the respective slots of the mounting portion 73, and the top end of the engaging piece 87 is positioned along the lower surface of the first protective wall 70 (the lower surface of the rod 11). In the standby position, the base 82 is positioned separately from the first protective wall 70 in the width direction.

[0098] The rod 11 is inserted from the rear into the rod storage chamber 27 of the housing 15. After the upper wall portion 28 flexes and deforms, the shaft portion 32 of the housing 15 is embedded into the bearing portion 62 of the rod 11. Furthermore, the rod 11 is held in a temporarily locked position relative to the housing 15 by the locking of the temporary locking piece 64 and the temporary locking receiving portion 59. Figure 2 As shown, at the temporary locking position, the rod 11 protrudes significantly behind the housing 15, so that the frame portion 79 and the locking arm 31 are located behind the housing 15.

[0099] Additionally, cover 16 is fitted onto housing 15. For example, as... Figure 18As shown, when it is desired to guide the wire 24 backward and to the other side in the width direction, the cover 16 allows the track portion 47 to slide along the track portion 34 from one side to the other in the width direction. The stop portion 51 abuts against the stop portion 38 within the notch portion 37, and the locking portion 48 elastically locks into the locking receiving portion 36, thereby holding the cover 16 in the correct installation position relative to the housing 15 in a movement-restricted state. Figure 2 As shown, the cover 16 is engaged by the track portion 47 and the engagement portion 35, thereby preventing the cover 16 from detaching from the outer shell 15.

[0100] As described above, when the cover 16 is correctly installed onto the housing 15, the closure portion 46 is disposed on one end side in the width direction, and the wire outlet 43 is disposed on the other end side in the width direction. Additionally, the rod 11 is disposed along the upper surface of an opposing wall 40, and the first movement path 56 is disposed on one end side in the width direction.

[0101] When lever 11 is in the temporary stop position and detection component 12 is in the standby position, such as Figure 2 As shown, the movable limiting portion 88 of the engaging tab 87 is positioned opposite to the first movable limiting portion 54 so as to abut against it from the rear. The protrusion 89 of the engaging tab 87 is embedded in the recess 58 of the first rib 52, and the pressed portion 90 of the protrusion 89 is positioned opposite to the first pressing portion 60 so as to abut against it from the inside. Furthermore, the detection member 12 is positioned near the side of the outlet tube 44.

[0102] Next, the connector body 10 is engaged with the counterpart housing 14. With the connector body 10 shallowly engaged within the cover 19 of the counterpart housing 14 and the cam follower 21 entering the entrance of the cam groove 63, the engagement of the temporary locking piece 64 and the temporary locking receiving part 59 is released by the counterpart housing 14. The operator presses the pressing surface 78 of the lever in the width direction, thereby rotating the lever 11 towards the final locking position. During the rotation of the lever 11, the movable limiting part 88 of the engaging piece 87 slides against the first movable limiting part 54, thereby restricting the movement of the detection member 12 towards the detection position. In addition, the pressed part 90 of the protrusion 89 touches the first pressing part 60, thereby preventing the detection member 12 from floating off the outer surface of the opposing wall 40.

[0103] As lever 11 approaches the final locking position, the movable limiting part 88 of the engaging piece 87 disengages from the first movable limiting part 54 and faces the first movement path 56. Additionally, as lever 11 approaches the final locking position, if... Figure 14As shown, the locking protrusion 68 interferes with the locking part 33, and the locking arm 31 flexes and deforms in the upper flexural space 69. At this stage, even if it is desired to move the detection member 12 to the other side of the width direction towards the detection position, the detection member 12 will not reach the detection position because the limiting surface 85 of the detection piece 84 touches one side of the locking arm 31.

[0104] When lever 11 reaches the final locking position, locking arm 31 elastically resets, as... Figure 15 As shown, the locking protrusion 68 is configured to oppose and lock against the locking part 33 from the front. This restricts the rearward rotation of the limiting lever 11. Furthermore, as... Figure 1 As shown, the stop 72 contacts the rear end edge of the upper wall 28, thereby restricting the forward rotation of the rod 11. Furthermore, the rear part of the locking arm 31 is disposed within the arm retraction portion 30 of the upper wall 28.

[0105] The locking arm 31 is elastically reset, allowing the detection piece 84 to enter the flexural space 69. As described above, the movable restriction portion 88 of the locking piece 87 is also configured to enter the first movement path 56. Therefore, when the operator presses the pressing surface 83 of the detection member on the other side in the width direction, the protrusions of each elastic locking portion 81 rest against each locking portion 80, allowing the detection member 12 to move towards the detection position. During the movement of the detection member 12 towards the detection position, the rib-shaped portion 86 and the guide rib 92 slide on each groove portion of the mounting portion 73, guiding the movement of the detection member 12.

[0106] When the detection component 12 reaches the detection position, such as Figure 17 As shown, the protruding portions of each elastic locking portion 81 are arranged opposite each other so as to abut against each locked portion 80 from the other side in the width direction. This restricts the movement of the detection member 12 in the direction of returning to its initial position. Furthermore, as... Figure 18 As shown, the other end face of the connecting portion 91 in the width direction is opposed to the wall portion 75 in a way that allows them to abut each other, thereby restricting the movement of the detection component 12 to the other side in the width direction than the detection position.

[0107] When the detection component 12 reaches the detection position, such as Figure 17 As shown, the detection piece 84 is positioned in the flexural space 69. Therefore, the upward flexing motion of the locking arm 31 is restricted by the detection piece 84, maintaining the locked state between the locking arm 31 and the locking part 33. Furthermore, as... Figure 18 As shown, the engaging piece 87 enters the first moving path 56 and retracts. The base 82 engages with the concave portion 74, and the entire assembly is housed in the mounting portion 73. Therefore, the detection component 12 does not have a portion protruding from the first protective wall 70 at the detection position.

[0108] On the other hand, contrary to the above method (the method of leading wire 24 backward and to the other side in the width direction), such as Figure 19 As shown, when it is desired to guide the wire 24 backward and to one side in the width direction, the cover 16 is reversed from the above posture, so that the track portion 47 slides along the track portion 34 and to one side from the other side in the width direction.

[0109] When the cover 16 is correctly installed onto the housing 15, as Figure 19 As shown, the blocking portion 46 is disposed on the other end side in the width direction, and the wire outlet 43 is disposed on one end side in the width direction. Additionally, the rod 11 is disposed along the upper surface of the other opposing wall 41, and the second movement path 57 is disposed on one end side in the width direction. The second movement limiting portion 55 and the second pressing portion 61 on the upper surface side of the cover 16 are arranged (shape, configuration) in the same way as described above. Therefore, as in the manner described above, rotation of the rod 11 and movement of the detection member 12 are possible.

[0110] As explained above, the connector according to this embodiment can achieve the following effects.

[0111] The detection component 12 is positioned on one of the two sides of the locking arm 31, facing one side. The two sides of the locking arm 31 are surfaces facing the width direction, which is orthogonal to the longitudinal direction (the length direction of the locking arm 31) and the vertical direction (the deflection direction of the locking arm 31). This avoids the problem of the connector becoming larger in both the longitudinal and vertical directions due to the presence of the detection component 12.

[0112] When the connector body 10 and the opposite housing 14 are properly engaged, the detection component 12 is in a state where it can move relative to the locking arm 31 from one side to the other. Thus, by pressing the detection component 12 into the other side in the width direction, it can be easily brought to the detection position.

[0113] The detection component 12 is held in a position to move to the mounting portion 73 of the first protective wall 70, which is located opposite to one side of the locking arm 31. Since the first protective wall 70 has both the function of protecting the locking arm 31 from the width direction and the function of holding the detection component 12, the configuration of the connector can be simplified compared to the case where the two functions are set separately.

[0114] A locking arm 31 is provided on the rod 11. The detection member 12 is held on the rod 11. Therefore, the locking arm 31 can be omitted from the housing 15, and the holding structure for the detection member 12 can be omitted from the housing 15. Thus, the configuration of the housing 15 can be simplified.

[0115] The lever 11 has a lever pressing surface 78 on the frame portion 79, which is pressed down in the engagement direction and protrudes rearward. The detection member 12 has a detection member pressing surface 83 on the base 82, which is pressed down in the detection direction and protrudes rearward. When the lever 11 is in the proper locking position, as... Figure 18 and Figure 19 As shown, the rod pressing surface 78 is positioned facing rearward, while the detection component pressing surface 83 is positioned facing one side in the width direction. That is, the rod pressing surface 78 and the detection component pressing surface 83 are positioned in opposite directions. Therefore, when the rod 11 is rotated to the final locking position, the rod pressing surface 78 can be pressed without contacting the detection component pressing surface 83. Similarly, when the detection component 12 is moved to the detection position, the detection component pressing surface 83 can be pressed without contacting the rod pressing surface 78. Thus, the rotation operation of the rod 11 and the movement operation of the detection component 12 can be performed smoothly without interference.

[0116] In addition, in this embodiment, the detection component 12 encounters the movement restriction parts 54 and 55 before the connector body 10 and the opposite side housing 14 are properly fitted, thus restricting its movement relative to the rod 11 toward the detection position.

[0117] In the past, when the rotating center shaft had a connector with a cantilever rod, the movement restriction part only needed to be provided on the opposite wall of the two opposing walls of the cover, on the side where the rod was located.

[0118] In contrast, in this embodiment, both opposing walls 40 and 41 are provided with movement restriction portions 54 and 55. Furthermore, each movement restriction portion 54 and 55 is positioned at the rearward center of the cover 16 (see [reference]). Figure 7 The symbol A) is centered and has a point-symmetric shape. Therefore, the cover 16 can be used in both directions (left or right). As a result, by simply rotating the cover 16 by 180°, the output direction of the wire 24 can be easily changed (see...). Figure 18 and Figure 19 ).

[0119] One of the two opposing walls 40 and 41, wall 40, has a first movement path 56 between one end of the first movement restriction portion 54 in the width direction and the blocking portion 46, and the other opposing wall 41 has a second movement path 57 between the other end of the second movement restriction portion 55 in the width direction and the wire outlet 43. Therefore, by using the shapes of the first movement path 56, the blocking portion 46, the second movement path 57, and the wire outlet 43 as a guide, the assembly posture of the cover 16 can be confirmed, and the possibility of incorrectly installing the cover 16 onto the housing 15 can be prevented.

[0120] Furthermore, in this embodiment, the connector body 10 has movement limiting portions 54 and 55 and pressing portions 60 and 61 on its outer surface side. The movement limiting portions 54 and 55 can contact the detection member 12 from the detection position side. The pressing portions 60 and 61 can contact the detection member 12 from an outer position. Since the connector body 10 has pressing portions 60 and 61 in addition to the movement limiting portions 54 and 55, it can prevent the detection member 12 from shifting in a direction separating from the outer surface side of the opposing walls 40 and 41. As a result, it can ensure that the detection member 12 contacts the movement limiting portions 54 and 55, thereby improving the reliability of the mating detection based on the detection member 12. In particular, in this embodiment, since the rod 11 is a cantilever type that is only provided on the outer surface side of either of the two opposing walls 40 and 41, it is easy for the rod 11 to detach from the outer surface side of the opposing walls 40 and 41. Therefore, the pressing portions 60 and 61 have the advantage of suppressing the floating of the detection member 12.

[0121] The movement limiting parts 54 and 55 and the pressing parts 60 and 61 are provided together on the rear edge (protruding end) of the side of the ribs 52 and 53 opposite to the detection member 12. Therefore, compared with the movement limiting parts 54 and 55 and the pressing parts 60 and 61 being provided in different positions, the structure of the connector body 10 can be simplified.

[0122] The connector body 10 has movement paths 56 and 57 on the outer surface of the cover 16. The ends of the movement paths 56 and 57 face the extending directions of the movement restriction portions 54 and 55. The detection member 12 has a detection piece 84 disposed in the flexural space 69 of the locking arm 31 at the detection position. Thus, even if the detection member 12 disengages from the movement restriction portions 54 and 55 and reaches the position facing the movement paths 56 and 57, it will encounter the locking arm 31, which flexes and deforms in the flexural space 69, through the limiting surface 85 of the detection piece 84, thereby restricting the movement of the detection member 12 to the detection position. Therefore, the accidental movement of the detection member 12 to the detection position can be effectively prevented before the connector body 10 and the opposite housing 14 are properly engaged.

[0123] [Other embodiments of this disclosure]

[0124] It should be considered that the embodiments disclosed herein are illustrative rather than limiting in all respects.

[0125] In the above embodiment, although the detection component is disposed on one side of the width direction of the locking arm, in other embodiments, the detection component may also be disposed on the other side of the width direction of the locking arm.
