The lock mechanism 800 can be configured by suppressing the protrusion of the lock mechanism 800 from the lid portion 500.

  In the connector 10 having such a configuration, when the lid portion 500 is in the closed state and the lock piece 822 is in the lock position, there is no portion that protrudes beyond the lid portion 500 in the −Z direction, and In addition, there is no portion that protrudes beyond the flange 300 in the XY plane (see FIGS. 2 and 3).

  When the operation member 850 is pressed to release the lock by the lock mechanism 800, the split lid portions 510 move to the corresponding rotation shaft 400 side by the spring force of the torsion spring 420 of the rotation shaft 400, and the XZ plane. It rotates so that it may become parallel (refer FIG.5 and FIG.6). In this process (see also FIG. 4), the area margin required for the displacement of the dividing lid 510 is very small.

  As shown in FIGS. 5 and 6, when the lid portion 500 is in the open state, the amount of protrusion of the lid portion 500 from the receiving portion 200 in the −Z direction can be suppressed. When the joint portion 52 is received by the receiving portion 200, the lid portion 500 does not get in the way.

  Since the two divided lid portions 510 are connected by the interlocking member 700, in order to shift the lid portion 500 in the open state to the closed state (close the lid portion 500), only one of the divided lid portions 510 is used. Move it. Therefore, the operation is not increased by dividing the lid 500 into the two divided lids 510.
