Abstract
Abstract An electrical connector comprises matable housing members and contact-carrying inserts. Matable electrical contact members are secured in passageways in each of the inserts and a coupling member holds the housing members, contact-carrying inserts, and electrical contact members in matable engagement. The housing members and the contact-carrying inserts include projections and flexible latching members to latchably secure the contact-carrying inserts in polarized positions in the housing members for proper matable engagement with each other. According to another aspect of the present invention, the flexible latching members including the polarizing areas of the contact-carrying inserts can be oriented relative to their respective housing members by angular selection to assure mating engagement between only these housing members and inserts so that proper electrical interconnection is made between electrical circuits.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
An insert-in-housing assembly for an electrical connector comprising a housing member, and a contact-carrying insert member latchably securable therein containing one or more electrical contact members, characterized in that: said contact-carrying insert member has an outer section having integral flexible latching means therearound, and said insert member has grooves underlying said integral flexible latching means, said housing member has an inner section having keying projections on each of which is located a latching projection; said keying projections correspond with said grooves and are matably engageable therewith to position said insert member in said housing member; said integral flexible latching means is capable of being flexed by said latching projections into said grooves as said latching projections move thereover during assembly of said insert member into said housing member and thereafter returning to an unflexed condition latchably engaging said latching projections when said insert member is in a fully mated condition in said housing;
Claim 2
Dependent Claim
153 words
An insert-in-housing assembly for an electrical connector comprising a housing member, and a contact-carrying insert member latchably securable therein containing one or more electrical contact members, characterized in that: said contact-carrying insert member has an outer section having integral flexible latching means therearound, and said insert member has grooves underlying said integral flexible latching means, said housing member has an inner section having keying projections on each of which is located a latching projection; said keying projections correspond with said grooves and are matably engageable therewith to position said insert member in said housing member; said integral flexible latching means is capable of being flexed by said latching projections into said grooves as said latching projections move thereover during assembly of said insert member into said housing member and thereafter returning to an unflexed condition latchably engaging said latching projections when said insert member is in a fully mated condition in said housing;
Claim 3
Dependent Claim
60 words
An electrical connector assembly as set forth in claim 1 wherein said insert member includes a pair of opposing ones of said grooves and said integral flexible latching means with said grooves being matably engageable with said keying projections thereby selectively positioning said insert member in said respective housing member relative thereto for proper matable engagement of said electrical members.
Claim 4
Dependent Claim
47 words
An assembly for an electrical connector as set forth in claim 1 characterized in that said integral flexible latching means and said latching projections have cooperating beveled surfaces enabling them to move easily over each other during positioning of said contact-carrying insert member into said housing member.
Claim 5
Dependent Claim
42 words
An assembly for an electrical connector as set forth in claim 1 characterized in that bottoms of said grooves have concave sections enabling said integral flexible latching means to flex thereinto as said integral flexible latching means moves along said latching projections.
