  • Connector with a terminal locking block
    Patent number: 5071373
    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.
