Abstract
A plastic double-lock member (40) with guide grooves (44) extending in a mating direction for guiding ribs in a matable connector. Integral end walls (48) are formed to close inner walls of the guide grooves (44) at end portions of the guide grooves (44). The end walls (48) are formed with latching lances (50) to engage with an insulating housing (20). The provision of the end walls (48) minimizes the non-uniformity of cooling of the plastic material which comprises the double-lock member (40), thereby reducing undesirable deformation of the double-lock member (40) caused during contraction of the plastic material after molding.
Claims14
A male electrical connector half for mating with a complimentary female electrical connector half, said male connector half comprising:
- an insulating housing having a plurality of contact insertion passages for receiving electrical contacts therein, and said insulating housing includes a double-lock member receiving cavity, said cavity is formed in a first exterior surface of the male connector half;
- a plastic double-lock member having contact insertion openings for alignment with the contact insertion passages, said double-lock member is shaped to fit into the double-lock member receiving cavity for locking said electrical contacts in said housing;
- and
- said double lock member further includes at least one guide groove formed in a second exterior surface adjacent said first exterior surface, said double-lock member having at least one end wall and at least one latching member for latching said double lock member into said housing.
An electrical connector for mating with a complementary connector comprising:
- an insulating housing having a plurality of contact passageways for receiving electrical contacts, a double-lock receiving cavity disposed in communication with said passageways having at least one double-lock guide groove, and at least one mating guide groove disposed on a surface of the housing perpendicular to said double-lock guide groove, and
- a double-lock member for insertion into said double lock receiving cavity having contact insertion openings for alignment with the contact receiving passageways, at least one latching member located at an end of a secondary guide groove which cooperates with said double-lock guide groove in the housing and latches said double-lock member to the housing in a position permitting insertion of the electrical contacts into the contact passageways, said secondary guide groove disposed on a major surface of said double-lock member which is aligned with said mating guide groove in the housing when said double-lock member is in a fully inserted position, and at least one projection on said double-lock member for maintaining said double-lock member in the housing in the fully inserted position so that the mating guide groove and the secondary guide groove are aligned to receive a rib on the complementary connector.
