Description of the Related Art As a conventional connector lock guarantee mechanism, a connector lock guarantee mechanism as shown in FIG. 9 has been proposed in Japanese Utility Model Laid-Open No. 1-165582. In the lock assurance mechanism of the connector shown in FIG. 9, in order to ensure the fitting of the male housing M and the female housing F, the lock assurance member M 1 is always mounted in one housing in a temporarily engaged state. When the male housing M and the female housing F are fitted together, the lock ensuring member M 1 moves from the temporary engagement position to the housing to the main engagement position to prevent the displacement of the lock arm a that locks the male and female housings. Both housings are kept locked.

ることを検知することができる。When the male housing M and the female housing F are in the half-fitted state, as shown in FIGS. 10 and 11, the engagement releasing drive rod b provided in the female housing F is a lock ensuring member. Since the flexible locking piece c of M 1 is not pushed up, the free end c 1 of the flexible locking piece c contacts the engaging protrusions d provided on both sides of the rising base of the lock arm a. Therefore, the lock ensuring member M 1 cannot be pushed into the male housing M. Therefore, by confirming the state in which the lock ensuring member M 1 cannot be pushed in, it is possible to detect that the fitting of the two housings is incomplete.

As shown in FIG. 12, the insertion of 1 is carried out by inserting the insertion ribs f of the lock assurance member M 1 into the assurance member insertion groove e of the male housing M. If there is looseness between the insertion ribs f and the lock securing member M 1
Is easily tilt, even the two housings in a semi-fitted state, the lock ensuring the pressing force is applied to the member M 1 is inclined lock ensuring member M 1 is large, the disengagement driving rod b is flexible engagement In spite of the state in which the stopper c is not pushed up, the free end c 1 of the flexible locking piece c disengages from the engaging projection d, and the lock ensuring member M 1 enters. Failure to detect it may result in failure.
If the insertion rib f is formed so as to be in close contact with the security member insertion groove e in order to eliminate the looseness between the security member insertion groove e and the insertion rib f, it is difficult to insert the lock security member M 1 for practical use. It has problems such as being impossible.
