ABSTRACT:
A connector housing has a pair of opposing inner walls in which is formed a plurality of terminal accommodating cavities. One of the inner walls is formed with a first terminal locking portion and the other inner wall is formed with an opening or window communicating with the cavity inside the walls. A terminal locking member is attached to the inner walls, and its terminal locking plate is installed in the window so that it can be moved sideways across the cavities in two steps, i.e., to the preliminary locked position and to the full locked position. The terminal locking plate has a second terminal locking portion or projections spaced at certain intervals. When the terminal locking member is in the preliminary locked position, the terminal can be inserted into or removed from the cavity, with an engagement piece of the terminal passing through the gap between the projections of the terminal locking plate. As the terminal is fully inserted into the cavity, the first locking portion automatically engages the terminal, effecting the first locking. Then as the locking member is slid laterally across the cavities to the fully locked position, the projections or the second terminal locking portion come directly behind the engagement piece, thus providing a second locking.
