ABSTRACT:
There is disclosed a connector in which there is no need to provide any separate or additional retaining arm, and a detection member (33) can be provisionally retained, and the construction of the connector is simplified, and the detection member is prevented from being lost. A fitting hole (31) in communication with a refuge space 29 for a terminal retaining piece portion (27) is formed in a connector housing, and is open to a front end face thereof. There is provided the detection member for being inserted into the fitting hole, and the detection member has an insertion plate (35a, 35b) for being inserted into the refuge space. The insertion plate has an insertion guide surface (43) for guiding the insertion of a mating connector terminal, (53) and a cantilever-like, elastic retaining arm, (45) having the guide surface at its free end, is formed at the insertion plate. A provisionally-retaining convex portion (41) is formed on the connector housing, and a provisionally-retaining projection (39) is formed on the insertion plate. In a retracted condition of the detection member in which the insertion plate is disposed out of the refuge space, the provisionally-retaining projection is retainingly engaged with the provisionally-retaining convex portion, thereby preventing the detection member from being withdrawn from the fitting hole.
