ABSTRACT:
The connector of this invention has a connector housing with a terminal accommodating chamber formed therein, into which a female terminal is to be assembled. A release bar is formed separately from the connector housing. With the release bar mounted on the connector housing, the female terminal is inserted into the connector. As the female terminal advances in the terminal accommodating chamber, its front end abuts against and then slides along the tapered surface of the front portion of the release bar, forcing it up. At the same time the female terminal slides over a lance formed in the connector housing. As it further advances, the front end of the lance engages with a hole in the underside of the female terminal and the front portion of the release bar snaps into an opening formed in the upper side of the female terminal. The female terminal in this way is doubly locked by the lance and by the front end of the release bar. If the lance fails to fit into the hole of the female terminal, the front portion of the release bar rests on the female terminal, projecting markedly from the houisng, which is easily recognizable from outside. This in turn alerts the assembly worker to the incorrect mounting.
