Then, the housing cover portion 55 of the first cover 21 is arranged so as to cover the rear portion of the housing 10, and the side wall portion of the first cover 21 is disposed at the side wall portion (the outer side wall portion 43 and the second wall portion 48) of the second cover 22. ), The protrusion receiving portion 67 of the first cover 21 and the protruding portion 44 of the second cover 22 mesh with each other, and the protruding end of the inner side wall portion 42 fits into the concave portion 68 of the first cover 21. The parts are fitted and inserted. Here, as described above, the floating of each electric wire 90 in the bent state in the bent portion 26 is suppressed by the height increase of the inner side wall portion 42 and the inclination of the inclined base wall portion 47, so that the first cover 21 and It is possible to prevent the electric wires 90 from being caught between the abutting ends of the side wall portions of the second cover 22.

  In addition, the pair of elastic lock portions 63A of the housing cover portion 55, the elastic lock portion 63B of the bending cover portion 57, and the pair of elastic lock portions 63C and 63D of the lead-out cover portion 58 in the first cover 21 respectively correspond to the second cover 22. By elastically locking the pair of lock portions 34A of the mounting portion 24, the lock portion 34B of the bent portion 26, and the pair of lock portions 34C and 34D of the lead-out portion 28 in FIG. They are held together.

  Further, the pair of guide portions 52A of the housing covering portion 55 are inserted into the pair of guide receiving portions 33A of the mounting portion 24 in a fitted state, and the pair of guide portions 52B of the second wall portion 48 are paired with the first wall portion 69. When the first cover 21 and the second cover 22 are inserted into the guide receiving portion 33B in the fitted state, the first cover 21 and the second cover 22 are prevented from being displaced in the direction intersecting the joining direction (see FIGS. 3 and 4). .

  Even if each of the electric wires 90 led out to the outside vibrates and an external force acts on the elastic lock portions 63A to 63D in a direction away from the corresponding lock portions 34A to 34D, the guide portions 52A and 52B resist the external force. Since the concavo-convex fitting state between the guide receiving portions 33A and 33B is maintained, the locked state between the elastic lock portions 63A to 63D and the lock portions 34A to 34D is not accidentally released. In particular, the pair of guide portions 52A of the housing covering portion 55 is covered on the outer side by the outer plate portion 31, and the pair of guide portions 52B of the second wall portion 48 is covered on the outer side by the guide wall 74 of the first wall portion 69. Thereby, it is possible to prevent the guide portions 52A and 52B from expanding outward.

  Even if the second wall portion 48 is deformed so as to fall inward with the inclined base wall portion 47 side as a fulcrum due to resin molding or the like, the first cover 21 and the second cover 22 approach each other. In the process of performing, the straightening portion 77 enters the wiring space 23 of the second cover 22, and the right and left falling straightening edge portions 83 of the straightening portion 77 are brought into sliding contact with the inner surface of the second wall portion 48, so that the second wall portion 48 is formed. It is corrected to a regular posture along the vertical direction. In this case, the inner surface of the second wall portion 48 slides along the inclined portion 84 of the correction portion 77 as the first cover 21 and the second cover 22 approach each other, so that the second wall portion 48 of the second wall portion 48 moves. The inward falling state will be gradually and smoothly resolved. In this way, the second wall portion 48 is corrected to the normal posture by the correction portion 77, so that the pair of guide receiving portions 62B of the second wall portion 48 face the pair of guide receiving portions 33B of the first wall portion 69. The insertable state can be secured, and the guide portion 52B and the guide receiving portion 33B can properly exhibit a predetermined function (such as a function of positioning the first cover 21 and the second cover 22).

  Furthermore, since the closing wall 75 having the correction portion 77 is integrally connected to the first wall portion 69 and has a box shape together with the first wall portion 69, the first wall portion 69 is formed due to resin molding or the like. It is possible to avoid a situation in which the object is deformed so as to fall inward.

  By the way, each electric wire 90 may be in a state of being floated from the electric wire guide surface 39 at the portion where the inclined base wall portion 47 transitions to the protruding piece wall portion 54. However, in the case of the first embodiment, since the first cover 21 and the second cover 22 are united with each other, the wire holding portion 82 of the correction portion 77 abuts on each wire 90 routed to the transition portion. It is possible to press 90 onto the wire guide surface 39 (see FIGS. 2 and 5). Therefore, the floating of each electric wire 90 is suppressed, and the floating of each electric wire 90 is also regulated.

  As described above, the connector is configured by attaching the wire cover 20 to the housing 10. Each electric wire 90 pulled out from the rear surface of the housing 10 is led out forward from the projecting piece wall portion 54, and when the connector is attached to an attachment target (not shown) such as a vehicle, a wall surface or the like is provided in a space behind the connector. Can be placed. Moreover, when the connector is attached to the attachment target, the peripheral component 100 is arranged in the space in front of the closing wall portion 76 (see FIG. 5). That is, the space corresponding to the height difference of the inclined base wall portion 47 extending from the bent portion 26 of the second cover 22 toward the end portion 27 is configured as the interference avoiding space 80 capable of avoiding the interference with the peripheral component 100. Become.

  As described above, according to the first embodiment, as shown in FIG. 2, the correction portion 77 is disposed so as to be capable of contacting the inner surface of the second wall portion 48, so that the second wall portion 48 moves inward. Since it is corrected to be deformed so as to fall, it is possible to favorably secure the state in which the guide structure including the guide portion 52B and the guide receiving portion 33B is fitted in the concavo-convex shape when united, and the guide portion 52B and the guide receiving portion 33B are secured. It is possible to properly exhibit a predetermined function such as a positioning function by the.

  Further, as shown in FIG. 9, the guide receiving portions 33B are provided in pairs on the first wall portion 69, and the first cover 21 and the second cover 22 are combined between the pair of guide receiving portions 33B. Since the elastic lock portion 63D that holds the state is provided and the tilting deformation of the second wall portion 48 is corrected by the correction portion 77, it is possible to improve the state in which the two guide receiving portions 33B and the two guide portions 52B are fitted in a concavo-convex shape. It is possible to secure the reliability, and it is possible to enhance the lock reliability of the elastic lock portion 63D provided between the pair of guide receiving portions 33B with respect to the lock portion 34D.

  In addition, the correction portion 77 is bent and connected to the first wall portion 69 so as to close the opening of the first cover 21, and the electric wire 90 can be pressed against the electric wire guide surface 39 of the second cover 22 which is opposed at the time of uniting. Since the electric wire pressing portion 82 is provided, the correction portion 77 can have both the function of restricting the collapse deformation of the second wall portion 48 and the function of suppressing the looseness of the electric wire 90, and both functions are provided in different parts. The entire configuration can be made simpler than that required.

  Further, according to the first embodiment, as shown in FIG. 6, the electric wires 90 pulled out from the rear surface of the housing 10 are connected to the inner wall portion before the first cover 21 and the second cover 22 are combined. 42 is bent and routed to the end portion 27 side. In this case, the inner side wall portion 42 is taller than the outer side wall portion 43, and the inclined base wall portion 47 is directed toward the end portion 27 side. Since the inner wall portion 42 is inclined toward the side opposite to the standing side, the electric wire 90 is routed in a direction that suppresses its floating, and the bent portion of the electric wire 90 floats and the inner wall portion 42 is lifted. It is possible to prevent more than 42 situations. As a result, it is possible to easily perform the subsequent combining operation of the first cover 21 and the second cover 22, and it is possible to prevent the electric wire 90 from being caught between the first cover 21 and the second cover 22.

  Further, the inclined base wall portion 47 extends forward from the base wall portion 41 of the bent portion 26 (a direction opposite to the direction in which each electric wire 90 is pulled out from the housing 10), and the inner side wall portion 42 is on the first cover 21 side. Since it has the curved guide portion 45 that is curved in a substantially U-shape when viewed from above, each electric wire 90 drawn out from the rear surface of the housing 10 is inverted to the end portion 27 side with the curved guide portion 45 as the bending center. Therefore, it is possible to more reliably prevent the bent portion (curved portion) of the electric wire 90 from floating.

  Further, as shown in FIG. 5, the space corresponding to the height difference between the bent portion 26 and the end 27 side of the second cover 22 is an interference avoiding space 80 capable of avoiding interference with the peripheral component 100. In addition, the inclination of the inclined base wall portion 47 has not only the function of suppressing the floating of the electric wire 90 but also the function of ensuring the interference avoiding space 80 capable of avoiding the interference with the peripheral component 100, and the configuration is simple. Can be
