The first lever 40 and the second lever 50 are compactly accommodated in the lever accommodating chamber 28 (see FIG. 1).

  The overlapping area is an area where the range surrounded by the outline of the first lever 40 in the front view and the range surrounded by the outline of the second lever 50 in the front view overlap, and are surrounded by the outline. When the through hole is formed within the range, the area is considered as having no through hole.

  As shown in FIG. 5, the second lever 50 is second in comparison with the distance (L3) from the second fulcrum (part of the second projecting shaft 54) to the second action point (part of the long groove 53). The distance (L4) from the fulcrum (a part of the second projecting shaft 54) to the second force point (a part of the bent portion 52) is set to be long.

  As shown in FIGS. 5 and 6, an elastic piece 55 for locking at the time of connector connection is connected to the bent portion 52 of the second lever 50 by a lower base end portion 55 </ b> A and cantilevered. The elastic piece 55 can be bent and deformed by pressing. A lock claw 55B protrudes from the substantially central portion of the elastic piece 55, and the lower surface of the lock claw 55B is an inclined sliding surface 155B (see FIG. 6). A stop portion 55C is formed to protrude from the distal end portion of the elastic piece 55, and the stop portion 55C is substantially parallel to the upper surface of the lock claw 55B. In addition, stopper portions 56 for restricting the bending deformation range of the elastic piece 55 are provided on both sides of the stop portion 55C at the distal end portion of the bent portion 52 shown in FIG.

  When the female connector 20 is pushed in the mounting direction (arrow C direction), as shown in FIG. 11, the protruding portion 16B of the protruding plate 16 in the male connector 10 presses the protruding portion 32C of the elastic piece 32 in the female connector 20. Thereby, the elastic piece 32 is elastically bent and deformed. As a result, the latching (locking) of the elastic piece 32 with respect to the first lever 40 is released, and the first lever 40 is allowed to rotate.

  In this state, a part of the bent portion 52 of the second lever 50 shown in FIG. 8, that is, the second force point, is directed to the final storage position (position shown in FIG. 9) of the second lever 50 (connection stage). Is pressed in the direction of arrow M), the second lever 50 rotates around the second shaft hole 26A (see FIG. 1). At this time, the pressing force applied to the second lever 50 is transmitted from a part of the long groove 53 (second action point) to a part of the projection 47 (first force point) of the first lever 40 in an amplified state. Part of the long groove 53 (second action point) drives the protrusion 47 having the first force point.

Engage and drive the female connector 20 close to the male connector 10 by input to the second force point (part of the bent portion 52), that is, drive in the attachment direction (arrow C direction). Therefore, the force of the connecting work after the terminals (terminals) contact each other can be greatly reduced, that is, the fitting load between the male connector 10 and the female connector 20 can be greatly reduced. Here, the reduction rate of the fitting load is obtained by the product of the reduction rate by the first lever 40 and the reduction rate by the second lever 50.

  Further, the projection 47 of the first lever 40 slides along the long groove 53 curved in the arc shape of the second lever 50, so that the pressing force applied to the second lever 50 is divided in the direction of attachment (arrow C direction). The force can be effectively transmitted to the first lever 40.
