Connector

A connector, comprising:

• a mating housing including a mating lock;
• a housing connectable to the mating housing and including a lock arm extending in a front-back direction and having a lock hole;
• and
• a detector assembled with the housing movably in the front-back direction between a standby position and a detection position and including a locking arm extending in the front-back direction and having a locking portion;
• a movement regulating portion provided on a rear part of the lock arm and configured to regulate a movement of the detector to the standby position by interfering with the detector at the detection position, wherein:
• the lock arm is deflected and deformed by interference of a front end part of the lock arm with the mating lock and the locking portion is inserted into the lock hole to lock the locking arm to the lock arm, whereby the detector is kept at the standby position in the process of connecting the two housings;
• the mating lock is fit into the lock hole to push out the locking portion as the lock arm returns, whereby locking between the locking arm and the lock arm is released to permit a movement of the detector to the detection position and the two housings are held in a state where separation of the two housings is restricted, when the connection of the two housings is completed;
• and
• the detector includes a contact portion-q displaceable together with the front end part of the lock arm during the interference of the front end part of the lock arm and the mating lock by contacting the front end part of the lock arm in a height direction intersecting with the front-back direction at the standby position, and the contact portion is formed to project forward after standing up in the height direction from a front end part of the locking arm so that an escaping space is defined above the locking arm and rearward of the contact portion, the movement regulating portion and the contact portion overlapping each other in the height direction so that the movement regulating portion is in the escaping space when the detector is in the detection position.
