CONNECTOR

PROBLEM TO BE SOLVED: To reduce looseness in fitting a connector. SOLUTION: While a lock arm 50 provided with a lock hole 52 is installed at the upper face of a female housing 20, a hood part 12 capable of housing the front part side of the female housing 20 is installed at a male housing 10, and a lock protrusion 13 lockable to the lock hole 52 of the lock arm 50 is formed at the outer periphery side of the hood part 12. As for the lock hole 52 and the lock protrusion 13, both housings 10, 20 are retained in a falling-off prevention state because a locking face 13a of the lock protrusion 13 is facing in the backward of a locking face 53 of the lock hole 52 because of such a constitution that both locking faces 13a, 53 are adhered in the falling-off prevention state, the shakiness in fitting is reduced. Furthermore, both of these locking faces 13a, 53 are arc faces having the swing center of the lock arm 50 as the center point, and slid and contacted to each other. Therefore, any trouble in a lock-release action is not caused. COPYRIGHT: (C)2005,JPO&NCIPI
