A connector and a connector assembly

摘要

An object of the present invention is to securely detect the incomplete mounting of a retainer.

A male housing 70 is provided with a receptacle 71 into which a female housing 20 is fittable, and an introducing surface 77 for introducing the female housing 20 is formed around the inner peripheral edge of the front end of the receptacle 71. A retainer 40 is provided with fastening sections for locking female terminal fittings when the retainer 40 is stopped at a full locking position, and an interfering portion 49 which can interfere with the receptacle portion 71 when the retainer 40 is mounted at an incomplete mount position IMP before reaching the full locking position. The interfering portion 49 is formed with a guiding surface 50 for guiding the entrance of the introducing portion 49 into the receptacle 71 when the retainer 40 is at the full locking position. The interfering portion 49 is formed with contact surfaces 57 in place of parts of the guiding surface 50. At positions of the inner peripheral edge of the front end of the receptacle 71 corresponding to the contact surfaces 57, receiving surfaces 79 to be brought into surface contact with the contact surfaces 57 are so formed in place of parts of the introducing surface 77 as to be located more backward than the introducing surface 77.
