Connector

A connector, comprising:

• a holder mounted on a first device in such a manner as to integrally move in an assembling direction of the first device and a second device, the holder including a peripheral wall and a stopper formed on an inner surface of the peripheral wall, a resiliently deflectable resilient locking piece formed on the holder so as to be inside the peripheral wall;
• a first housing provided movably with respect to the holder substantially in the assembling direction of the second device with the first device, a resiliently deflectable resilient contact piece being formed on an outer surface of the first housing;
• a lock formed on the first housing to regulate a movement of the first housing with respect to the holder by locking the resilient locking piece;
• a second housing mounted on the second device so as to move integrally in the assembling direction of the first and second devices;
• and
• a lock releasing portion formed on the second housing;
• wherein:
• the first and second housings are connected properly and the lock releasing portion resiliently deflects the resilient locking piece to separate the resilient locking piece from the lock in the process of assembling the first and second devices;
• the first housing moves with respect to the holder while being kept properly connected to the second housing as assembly of the first and second devices proceeds when locking between the resilient locking piece and the lock is released;
• the resilient contact piece is deflected resiliently by interference with the stopper when assembling the first housing into the peripheral wall from a side opposite to a side to be connected to the second housing;
• and
• the resilient contact piece is locked to the stopper to regulate detachment of the first housing from the holder toward a side opposite to a side to be connected to the second housing with the first housing assembled in the peripheral wall.
