Abstract
The connector consists of a connector housing having terminal accommodating chambers, and a terminal locking block which is mounted to the rear portion of the connector housing in two steps, first in a provisionally-engaged condition and then in a full-engaged condition. When the terminal locking block is half-coupled to the connector housing, a full-engaging projection member formed on the terminal locking block contacts an inclined guide inner surface formed in a locking block receiving opening in the rear part of the connector housing. At the same time, engagement projections of full-engaging members formed on the terminal locking block abut against the provisionally-engaging portion of the connector housing. In the provisionally-engaged condition, the front ends of terminal holding pieces projecting forwardly from the terminal locking block are located out of the terminal lug insertion paths in the terminal accommodating chambers, so that terminal lugs can freely be inserted into or removed from the terminal accommodating chambers. Moving the terminal locking block from the provisionally-engaged position to the full-engaged position requires disengaging the full-engaging members from the provisionally-engaging portion of the connector housing. This prevents an inadvertent shifting of the terminal locking block into the full-engaged position.
