And a pair of guide portions 53 protruding forward. In a substantially lower half region on the front surface of the back plate 51, vertical positioning grooves 54 for positioning the electric wires 46 one by one are formed in parallel on the left and right. A shelf portion 55 is formed at a substantially central height on the front surface of the back plate 51 so as to protrude horizontally forward and continue between the inner surfaces of the lock pieces 52.

  The lock piece 52 has a rectangular flat plate shape parallel to the assembly direction of the wire cover 50 with respect to the housing 10 and parallel to the left and right outer surfaces of the housing 10. The upper and lower surfaces of the lock piece 52 are flush with the upper and lower surfaces of the back plate 51, respectively. The lock piece 52 expands in the left-right direction (the thickness direction of the lock piece 52 and the direction intersecting the assembly direction of the wire cover 50 with respect to the housing 10) with the rear end edge continuous to the back plate 51 as a fulcrum. When the lock piece 52 is elastically deformed, the plate surface is inclined with respect to the assembly direction to the housing 10. The lock piece 52 is formed with a substantially rectangular lock hole 56 penetrating in the left-right direction (the thickness direction of the lock piece 52) so as to correspond to the lock portion 24 of the housing 10.

  On the inner surface of the lock piece 52, a rib 57 extending in the front-rear direction (a direction parallel to the assembly direction with respect to the housing 10) is formed. The upper surface and the lower surface of the rib 57 serve as contact surfaces 58 that are parallel (horizontal) to the assembly direction with respect to the housing 10. The rib 57 projects forward from the shelf 55, and the front end portion of the rib 57 projects forward from the front end edge of the lock piece 52. The lower contact surface 58 of the rib 57 is continuous with the lower surface of the shelf 55. The rib 57 is bent integrally with the lock piece 52. An abutting portion 59 is formed on the inner surface of the lock piece 52 so as to extend upward from the rear end portion of the rib 57.

The thickness of the guide portion 53 (the size in the left-right direction) is constant over the entire region, and the plate surface, that is, the extending direction of the guide portion 53 from the back plate 51, is the assembly of the wire cover 50 to the housing 10. Parallel to the direction. The guide portion 53 has a square shape, and the lower surface thereof is the same height as the upper surface of the shelf portion 55. Further, the front end edge of the guide portion 53 is located at the same position as the front end edge of the lock piece 52 in the front-rear direction (the assembly direction of the wire cover 50 with respect to the housing 10). Further, the upper surface of the guide portion 53 is set to the same height as the upper surface of the lock piece 52. Further, the pair of left and right guide portions 53 are positioned so as to sandwich the operation portion 13A of the lock arm 13 from both the left and right sides when the electric wire cover 50 is assembled to the housing 10. In the process in which the operation portion 13A is displaced up and down during the unlocking operation, the inner surface of the guide portion 53 always faces the left and right outer surfaces of the operation portion 13A with a slight gap therebetween. . That is, the pair of guide portions 53 regulates the shake of the operation portion 13A in the left-right direction by sandwiching the operation portion 13A moving up and down from both the left and right sides during the unlocking operation.

  Next, the operation of this embodiment will be described.

  After the retainer 40 is fully locked, an electric wire cover 50 is assembled from the rear so as to cover the electric wires 46 at the rear end portion of the housing 10. When assembling, first, the front end portions of the pair of left and right ribs 57 abut against the rear end portion of the abutting surface 18 of the die cutting space 16 from the outer surface side, and then the abutting state between the ribs 57 and the abutting surface 18 While the (surface contact state) is maintained, the left and right guide portions 53 abut against the sliding contact surface 15 inside the wall portion 14 in a surface contact state, and then the leading edge of the lock piece 52 guides the lock portion 24. It abuts against the surface 26. Thereafter, when the assembly of the electric wire cover 50 is further advanced, the lock piece 52 is elastically bent so as to expand to the outer surface side by climbing on the guide surface 26. While the lock piece 52 is elastically bent, the left and right guide portions 53 are in sliding contact with the left and right wall portions 14 in a surface contact state from the inside, so that the electric wire cover 50 is moved in the left and right direction (the lock piece). Displacement in the direction substantially the same as the elastic deflection direction of 52) is restricted. The left and right ribs 57 are separated from the contact surface 18 while the lock piece 52 is elastically bent.

  Furthermore, as the assembly of the electric wire cover 50 proceeds, the left and right ends of the shelf 55 are fitted between the wall 14 and the extension 23 while the lock piece 52 is elastically bent, and the shelf 55 The upper surface and the lower surface of the first and second lower surfaces respectively contact the pressing surface 20 of the wall portion 14 and the support surface 27 of the extending portion 23 in the vertical direction. This restricts the electric wire cover 50 from being displaced in the vertical direction with respect to the housing 10. In the process of assembling the electric wire cover 50, the electric wire 46 led out substantially horizontally rearward from the rear end surface of the housing 10 is gradually pushed downward by being pushed by the back plate 51 while being fitted in the positioning groove 54. It will be bent.

  When the electric wire cover 50 is assembled at the normal position, the front end portion of the lock piece 52 finishes passing through the lock portion 24, so that the lock piece 52 is elastically restored inward and the lock hole 56 and the lock portion 24 are fitted. Thus, the front end edge of the lock hole 56 is engaged with the engagement surface 25 of the lock portion 24 from the front. Accordingly, the electric wire cover 50 is in a locked state in which the electric wire cover 50 is restricted from being detached rearward with respect to the housing 10. In this locked state, the electric wire 46 whose direction is changed downward between the back plate 51 of the electric wire cover 50 and the rear end surface of the housing 10 is led downward from the gap between the electric wire cover 50 and the housing 10. Further, the abutting surface 60 of the electric wire cover 50 abuts against the stopper surface 22 of the housing, so that the front cover is stopped.

  Further, when the lock piece 52 is elastically restored, the rib 57 is fitted into the die cutting space 16, and the inner side surfaces of the left and right ribs 57 abut against the left and right abutting surfaces 18 in a surface contact state from the outside. The upper abutment surface 58 and the lower abutment surface 58 are in surface contact over a predetermined length in the front-rear direction with respect to the upper receiving surface 17 and the lower receiving surface 17 of the cut-out space, respectively. Abut in state. Due to the contact between the contact surface 58 and the receiving surface 17, the wire cover 50 is displaced in the vertical direction with respect to the housing 10, that is, the posture is displaced so as to translate in the vertical direction, or tilt forward or backward. Is regulated.

  Further, since the outer surfaces of the left and right guide portions 53 are in contact with the sliding contact surfaces 15 inside the left and right wall portions 14 in a surface contact state, the wire cover 50 is displaced in the left-right direction with respect to the housing 10. That is, it is restricted that the head is displaced so as to swing the head in the left-right direction, and that it is tilted in the left-right direction. In addition, since the guide portion 53 sandwiches the wall portion 14 between the rib 57 and the left and right, the stability of the position and posture of the electric wire cover 50 is high.

  As described above, in the present embodiment, the housing 10 is formed with the receiving surface 17 extending in substantially the same direction as the assembly direction of the wire cover 50 and substantially perpendicular to the outer surface on which the lock portion 24 is formed, In the electric wire cover 50, a contact surface 58 that extends in substantially the same direction as the assembly direction to the housing 10 and that can contact the receiving surface 17 is formed, and the electric wire cover 50 is assembled and locked to the housing 10. Since the receiving surface 17 and the contact surface 58 are in contact with each other in a surface contact state, it is possible to prevent the electric wire cover 50 from being displaced in the vertical direction, that is, in the direction orthogonal to the assembly direction to the housing 10. it can.

  When the electric wire cover 50 is assembled to the housing 10 and the contact surface 58 of the electric wire cover 50 is in contact with the receiving surface 17 of the housing 10, the ribs 57 of the electric wire cover 50 are fitted into the die-cutting space 16 of the housing 10. However, this means that the die-cutting space 16 is also used as a space for fitting the rib 57 of the electric wire cover 50, whereby the connector can be miniaturized. Yes.

  Further, the wire cover 50 is formed with a guide portion 53 that protrudes in the same direction as the assembly direction with respect to the housing 10, and the housing 10 is formed with a sliding contact surface 15 that intersects the elastic bending direction of the lock piece 52. In the process of assembling the electric wire cover 50, the guide portion 53 is in sliding contact with the sliding contact surface 15, so that the electric wire cover 50 is displaced with respect to the housing 10 in substantially the same direction as the elastic deflection direction of the lock piece 52. Being regulated. Thereby, the elastic bending operation | movement of the lock piece 52 is performed stably and the assembly workability | operativity of the electric wire cover 50 improves.

Further, in a state where the electric wire cover 50 is assembled to the housing 10, the rib 57 and the guide portion 53 sandwich the wall portion 14, so that the displacement of the electric wire cover 50 in the substantially same direction as the elastic bending direction of the lock piece 52 is ensured. As a means for restricting the displacement of the electric wire cover 50, the rib 57 as a means for restricting the backlash of the electric wire cover 50 and the elastic bending operation of the lock piece 52 when the electric wire cover 50 is assembled. Since the guide portion 53 which is a means for stabilizing is utilized, the shape can be simplified and the size can be reduced as compared with a case where a dedicated means for displacement control is provided.
Further, when the lock 13 is pushed downward to release the lock, the pair of guide portions 53 guide the operation portion 13A by sandwiching the operation portion 13A from the left and right, so that the operation portion 13A is moved in the left-right direction. Without being displaced straight up and down along a predetermined path. Therefore, the unlocking operation can be performed stably.
