ABSTRACT:
Engaging structure of a terminal and a connector housing comprises a contact piece 5 and an electric wire connecting portion 7, and can be inserted into a terminal receiving cavity 23 of a housing 22, which includes a retainer 28 provided with a detecting protrusion 57. The terminal 1 is provided with a projecting portion 9 which allows the retainer to be moved to the primary locking position, by slipping off from a moving path of the detecting protrusion 57 toward the front side B of a terminal insertion direction, when the retainer is at the provisional locking position and the terminal is completely inserted at the normal position, and which prevents the retainer 28 to be moved to the primary locking position, by abutting against the detecting protrusion 57, when the terminal 1 is incompletely inserted before the normal locking position. The projecting portion 9 is provided with a detection hole 73 for detecting faulty insertion of the terminal. The detection hole is engaged with the detecting protrusion 57 when the terminal 1 is inserted with the retainer 28 located at the primary locking position. Thereby, easy detection for falsely insertion of a terminal into a housing with a retainer locked at a primary locking position can be ensured.
