The tab portion 18 of the one-terminal metal fitting 15 is inserted at a normal depth, and the tab portion 18 is in electrical contact with the contact area in the box portion 46. As a result, the first terminal fitting 15 and the second terminal fitting 45 are connected to each other.

As shown in FIG. 1, the first housing 11 has a pair of support shafts 21 at the substantially central portion in the front-rear direction on both outer surfaces. A lever 22 is rotatably supported on both the support shafts 21.
The lever 22 is made of a synthetic resin and has a gate shape as a whole as shown in FIG. 6, and protrudes substantially parallel to each other from the connecting portion 23 along the width direction and from both ends of the connecting portion 23 in the width direction. And a pair of arm portions 24. The arm portion 24 has a plate shape and has a bearing hole 25 and a cam groove 26. As shown in FIG. 3, the cam groove 26 extends in a curved shape and opens at the outer peripheral edge of the arm portion 24. A support shaft 21 is fitted in the bearing hole 25 (see FIG. 1), and the lever 22 is rotatable between an initial position and a fitting position with the fitted support shaft 21 as a center. In the initial position, the entrance of the cam groove 26 is disposed so as to open forward, and the connecting portion 23 is disposed behind the first housing 11. In this state, when the first connector 10 and the second connector 40 are shallowly fitted, the cam follower 54 of the second connector 40 enters and is arranged at the entrance of the cam groove 26.

Both the leg portions 28 have a pair of small projection-shaped regulation receiving portions 31 on the outer surface facing the shaft portion 30 side. In addition, as shown in FIG. 2, a receiving portion 32 is provided on the outer surface of the lock main body 29 so as to be cut into a substantially L-shaped section or a substantially U-shaped section. The shaft portion 30 has a columnar shape extending with substantially the same diameter over the entire width.

  The detection member 60 is made of a synthetic resin, and is attached to the lever 22 so as to be rotatable around the shaft portion 30 between a standby position and a detection position. As shown in FIG. 7, the detection member 60 includes a rotating portion 61 having a substantially C-shaped cross section extending in the width direction and one end portion in the circumferential direction (of the rotating portion 61 in FIG. 7). The width of the substantially rectangular block-shaped locking projection 62 projecting substantially radially outward from the substantially central portion in the width direction of the upper edge of the opening) and the other circumferential end (the lower edge of the opening of the rotating portion 61 in FIG. 7) A pair of band-plate-like disengagement portions 63 extending substantially radially outward from the substantially central portion in the direction and a pair projecting substantially radially outward from positions on both sides in the width direction across the disengagement portion 63 at the other circumferential end. And a rib-shaped protrusion 65 that extends in the width direction at the other end in the circumferential direction and is connected to the engagement release portion 63 and both the restriction portions 64. In detail, the rotating part 61 has a cross-sectional arc shape, and is configured with the same diameter over the entire length in the width direction. The inner peripheral circular arc surface of the rotating portion 61 is substantially concentric with the shaft portion 30, and the inner diameter of the rotating portion 61 is slightly larger than the outer diameter of the shaft portion 30. Both restricting portions 64 are arranged in parallel with the disengaging portion 63 in parallel with each other.

The above is the structure of the connector of this embodiment, and the operation will be described.
First, the detection member 60 is attached to the lever 22. At this time, the shaft portion 30 is elastically inserted inside the rotating portion 61 through the openings between the circumferential ends of the rotating portion 61, and the detection member 60 is accommodated inside the recess 27. As shown in FIG. 2, the detection member 60 is held at the standby position with respect to the first connector 10 by the front end portions of the two restricting portions 64 of the rotating portion 61 coming into contact with the front end surfaces of the two restricting receiving portions 31 Rotation toward the detection position is restricted. When the detection member 60 is in the standby position, the distal end portion of the disengagement portion 63 is disposed in the space between both leg portions 28.

  Thereafter, as shown in FIG. 5, when the first connector 10 and the second connector 40 are properly fitted to each other, the lock main body portion 29 of the lever 22 is elastically fitted into the lock recess 52 of the second connector 40. When the lock main body 29 comes into contact with the release portion 53, the lever 22 is held in the rotation restricted state at the fitting position, and the first connector 10 and the second connector 40 are held in the fitted state. As shown in FIG. 3, when the first connector 10 and the second connector 40 are properly fitted to each other, the release portion 53 enters the space between both the leg portions 28, and the release portion 53 is engaged with the engagement release portion 63. The entire tip of the detection member 60 is lifted by pressing the front end. Then, the rotating part 61 is displaced in the direction of being misaligned with respect to the shaft part 30, the both restricting parts 64 are separated from the both restricting receiving parts 31, and the engagement with the both restricting receiving parts 31 is released. The rotation to the detection position is allowed.

  Subsequently, as shown in FIGS. 3 to 5, the rotating portion 61 is rotated counterclockwise around the shaft portion 30. As shown in FIG. 5, when the detection member 60 reaches the detection position, the locking projection 62 fits into the receiving portion 32 of the lock main body portion 29, whereby the rotation portion 61 is held in the rotation restricted state at the detection position. The At this time, the disengagement part 63 is disposed substantially horizontally. Therefore, it can be known that the detection member 60 has reached the detection position by confirming the posture or position of the engagement release portion 63 or the locking protrusion 62.

  On the other hand, if the first connector 10 and the second connector 40 are held in the middle until they are properly fitted, the lock main body 29 of the lever 22 does not reach the position where it is locked to the lock 51 and the detection member The engagement release portion 63 of 60 does not reach the position where it comes into contact with the release portion 53. For this reason, the engagement between both restriction portions 64 and both restriction receiving portions 31 is maintained, and rotation of the detection member 60 to the detection position is prevented. That is, the detection member 60 cannot be rotated unless the first connector 10 and the second connector 40 are properly fitted.

  As described above, according to the present embodiment, the first connector 10 and the second connector are confirmed by checking the state in which the rotating portion 61 of the detecting member 60 rotates around the shaft portion 30 from the standby position to the detecting position. 40 can be determined to be in a properly fitted state. Because the connector fitting is detected based on the rotation of the rotating portion 61, unlike the conventional case where the detection member 60 moves straight, the first connector 10 has a moving stroke for the detection member 60. Therefore, it is not necessary to secure a space for the connector, and an increase in size of the entire connector can be avoided.

  Further, as the first connector 10 and the second connector 40 are properly fitted, the release portion 53 presses the engagement release portion 63 to change the relative position of the rotation portion 61 with respect to the shaft portion 30, thereby restricting the restriction. Since the engagement between the portion 64 and the restriction receiving portion 31 is released, the rotating portion 61 is quickly and smoothly rotated to the detection position. Further, since the shaft portion 30 is provided on the lever 22, the configuration of the first housing 11 is not complicated.
