The lever side protrusion 58 is positioned in front of the lever side second contact surface 52. The rear surface 57 of the lever side protrusion 58 constitutes the lever side first contact surface 51.

  The housing-side first contact surface 41 and the housing-side second contact surface 42 are both provided on the housing-side projection 40 as shown in FIG. The housing side protrusion 40 protrudes rearward from the rear surface 57 of the housing 10. The housing side protrusion 40 is a rigid body having high rigidity in the contact direction with the lever side protrusion 50. As shown in FIG. 10, the protruding dimension of the housing-side protrusion 40 (the dimension in the front-rear direction) is equivalent to the dimension of the lever-side protrusion 50 in the front-rear direction. The housing-side protruding portion 40 is arranged side by side with the shaft portion 12 (positions in the front-rear direction are substantially the same). As shown in FIG. 3, a pair of housing side protrusions 40 are provided on both the upper and lower sides of the housing 10, and both have a plate shape protruding along the upper and lower surfaces of the housing 10. The upper and lower surfaces of each housing-side protrusion 40 stand substantially perpendicular to the rear surface of the housing 10.

  A housing-side first abutment surface 41 and a housing-side second abutment surface 42 are provided on the surface of the peripheral surface 44 of the housing-side protrusion 40 opposite to the shaft portion 12.

As shown in FIG. 10, the housing side protrusion 43 has a trapezoidal shape in which both front and rear surfaces are inclined surfaces. The front surface 56 of the housing-side protrusion 43 constitutes the housing-side first contact surface 41, and the protruding end surface of the housing-side protrusion 43 constitutes the housing-side second contact surface 42.

  The rear surface 45 of the housing-side protrusion 40 is substantially orthogonal to the housing-side second contact surface 42.

Next, the single connector C of the present embodiment will be described.
The lever 20 is attached to the single connector C at the initial position. In the initial position of the lever 20, as shown in FIG. 10, the housing-side protrusion 40 and the lever-side protrusion 50 are arranged side by side, and the housing-side protrusion 43 is located on the rear side of the lever-side protrusion 58. positioned. The pair of first contact surfaces 41, 51 and the pair of second contact surfaces 42, 52 are opposed to each other so as to be substantially parallel to each other. The pair of first contact surfaces 41, 51 and the pair of second contact surfaces 42, 52 are in contact with or close to each other. The elastic part 55 of the lever side protrusion part 50 is in a natural state where it does not elastically bend. Further, the operation portion 22 of the lever 20 is disposed at a position away from the rear surface of the housing 10 and is located at an end in the left-right direction of the electric wire cover 30 (end opposite to the outlet 31). The operation unit 22 protrudes laterally (rightward in FIG. 10) from the side surface of the wire cover 30.

  The single connector C with the lever 20 attached to the initial position in this manner may be inadvertently dropped from the work table at a harness factory or the like, and the operation unit 22 may hit the floor surface. In such a case, the connector C falls with the operation unit 22 facing down, and an upward impact is applied to the operation unit 22. As a result, the pair of second contact surfaces 42 and 52 arranged to face each other come into contact with each other, so that the impact of the operation unit 22 is received. Therefore, since the impact is not concentrated on the bearing portion 24 and the shaft portion 12 in the fitted state, the shaft portion 12 can be prevented from being broken.

Next, an example of the fitting operation of the connector C of this embodiment will be described.
When the connector C is fitted, the mating connector 80 is fitted, and the cam pin 81 of the mating connector 80 enters the cam groove 26 of the lever 20. Thereafter, the lever 20 is rotated from the initial position to the fitting completion position. When the operation unit 22 is moved toward the outlet 31 side of the wire cover 30, the pair of first contact surfaces 41, 51 arranged to face each other come into contact with each other, and the elastic portion 55 eventually becomes the bending space S. The lever-side first contact surface 51 is detached from the housing-side first contact surface 41 due to elastic bending, and the lever-side protrusion 58 rides on the protruding end surface of the housing-side protrusion 43. Thus, the contact state between the pair of first contact surfaces 41 and 51 is released, and the lever 20 can be rotated. As the lever 20 rotates, the lever-side protrusion 58 is displaced along the inclination of the rear surface of the housing-side protrusion 43, and the elastic portion 55 is elastically restored to a natural state. Further, when the mating connector 80 is drawn by the engagement between the cam groove 26 and the cam pin 81 and the lever 20 reaches the fitting completion position, the connectors C and 80 are brought into a normal fitting state. At this time, the lock portion 23 is engaged with the lock receiving portion 32, and the lever 20 is restricted from returning to the initial position. Thus, the fitting operation between the connector C and the mating connector 80 is completed.

Next, the operation and effect of the present embodiment configured as described above will be described.
The connector C of the present embodiment is attached to the housing 10 and the housing 10, and is rotated from the initial position to the fitting completion position around the shaft portion 12 by operating the operation portion 22, and the connectors C and 80 are connected. It has a lever 20 that leads to normal fitting and an initial lock structure R of the lever that holds the lever 20 in the initial position. The initial lock structure R of the lever includes a pair of first contact surfaces 41 and 51 that are in contact with each other in the rotation direction of the lever 20 at the initial position of the lever 20 and the operation portion 22 pressed toward the shaft portion 12 side. And a pair of second contact surfaces 42 and 52 that come into contact with each other. According to this configuration, even when an impact is applied to the operation unit 22, it is possible to prevent the impact from being concentrated on the shaft portion 12 by the contact between the pair of second contact surfaces 42 and 52. Therefore, the shaft portion 12 can be protected in the single connector C.

  The lever 20 and the housing 10 have one housing-side protrusion 40 having both the housing-side first contact surface 41 and the housing-side second contact surface 42, the lever-side first contact surface 51, and the lever-side first. And a lever-side protrusion 50 having both two contact surfaces 52. According to this configuration, the structure of the housing 10 can be simplified as compared with the case where the housing is provided with a protrusion having a housing-side first contact surface and a housing-side second contact surface separately. Further, the structure of the lever 20 can be simplified as compared with the case where the lever is provided with a protrusion having the lever side first contact surface 51 and the lever side second contact surface 52 separately.

  Further, the lever-side first contact surface 51 can be elastically bent in a direction to be released from a state in which the lever-side first contact surface 41 is in contact with the housing-side first contact surface 41 by a force to rotate the lever 20 to the fitting completion position. A pair of second contact surfaces 42 and 52 are provided on the rigid body portion 54 that is not elastically bent. According to this configuration, when the lever 20 is to be rotated from the initial position to the fitting completion position, the elastic portion 55 is elastically bent and the contact state of the first contact surfaces 41 and 51 is released. The lever 20 can be easily rotated. Further, even if a strong impact is applied to the operation portion 22, the pair of second contact surfaces 42 and 52 are held in contact with each other, so that the shaft portion 12 can be reliably protected.

  Further, the rigid body portion 54 protrudes integrally with the lever 20, and the elastic portion 55 is supported by the rigid body portion 54. According to this structure, space efficiency can be improved compared with the case where the elastic part 55 and the rigid part 54 are provided separately.

  The lever 20 includes the cam plate portion 21, and the elastic portion 55 is provided on the cam plate portion 21 and is elastically bent in a direction along the plate surface 27 of the cam plate portion 21. Here, when the elastic portion is elastically bent in the plate thickness direction of the cam plate portion, the cam plate portion may be deformed in the plate thickness direction together with the elastic portion. However, according to the configuration of this embodiment, the cam plate It is possible to prevent the portion 21 from being deformed as such.
