Double-lock electrical connector

An electrical connector housing, comprising:

• a dielectric housing member having at least one row of contact-receiving chambers extending from a contact-receiving end to a front end for receiving electrical contacts terminated to wires therein, said housing member positioned inwardly approximately midway between said insertion end and said front end and intersecting said contact-receiving chambers;
• first latching surfaces provided by said contact-receiving chambers adjacent the opening in said wall;
• second latching surfaces provided by said contact-receiving chambers adjacent the opening in said wall;
• a dielectric locking member profiled to fit within said opening and having holes including edge surfaces therethrough;
• first latching means on said locking member engagable with said first latching surfaces when said locking member is inserted within said opening to maintain said locking member at a first position thereby aligning said holes of said locking member with said contact-receiving chambers so that electrical contacts can be inserted within the contact-receiving chambers;
• and
• second latching means on said locking member engagable with said second latching surfaces when said locking member is moved further into said opening to maintain said locking member at a second position so that edge surfaces of said holes of said locking member engage the electrical contacts positioned in the contact-receiving chambers at a point removed from the point of wire termination to prevent backing out of the contacts therefrom due to wire strain.
