Abstract
Abstract The invention is an electrical connector assembly of the type having a housing (15); a rubber moisture sealing grommet (20) and a contact retaining insert (10) characterized by a plurality of passages (15) that contain a plurality of pivotally mounted (13) and radially deflectable arcuate segments (11) that include on the inside thereof a radially inwardly projecting shoulders (12) that engage a groove (32) of a contact (30) located in a passage (15). A tool may be inserted into the passage to pivot the arcuate segments (11) so that the shoulders (12) disengage the groove (32) in the contact (30) thereby releasing the contact (30) for removal from the passage (15).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
212 words
In combination with an electrical connector having removable contacts said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an annular groove between said forward and rear portions, and means for releasably mounting said contacts in said housing including an insert having a plurality of bores therein, each bore having therein a portion of a respective contact having the annular groove therein and a contact retention member, the improvement wherein said contact retention member comprises: an arcuate segment having forward and rear ends spaced from the wall of said bore and on the inside thereof an inwardly projecting shoulder engaging the annular groove in a respective contact, and on the outside thereof between said ends, means for pivotally mounting to said insert the arcuate segment in each bore so that either end of said arcuate segment may be deflected to disengage the projecting shoulder from the groove in the contact whereby, a tool may be inserted into a bore in said insert to engage and pivot said arcuate segment in said bore so that the projecting shoulder of the segment disengages from the groove in the contact thereby releasing the contact in said bore for removal from the connector.
Claim 2
Dependent Claim
212 words
In combination with an electrical connector having removable contacts said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an annular groove between said forward and rear portions, and means for releasably mounting said contacts in said housing including an insert having a plurality of bores therein, each bore having therein a portion of a respective contact having the annular groove therein and a contact retention member, the improvement wherein said contact retention member comprises: an arcuate segment having forward and rear ends spaced from the wall of said bore and on the inside thereof an inwardly projecting shoulder engaging the annular groove in a respective contact, and on the outside thereof between said ends, means for pivotally mounting to said insert the arcuate segment in each bore so that either end of said arcuate segment may be deflected to disengage the projecting shoulder from the groove in the contact whereby, a tool may be inserted into a bore in said insert to engage and pivot said arcuate segment in said bore so that the projecting shoulder of the segment disengages from the groove in the contact thereby releasing the contact in said bore for removal from the connector.
Claim 3
Dependent Claim
18 words
The combination as recited in claim 1 wherein there are at least two arcuate segments in each bore.
Claim 4
Dependent Claim
190 words
In combination with an electrical connector having removable contacts, said connector of the type having a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an annular groove between said forward and rear portions; an insert having a plurality of bores each having a rear portion of a respective contact therein; and means for releasably mounting said contacts in a respective bore, said means including a plurality of contact retaining members in each of said bores, the improvement wherein each of said contact retaining members comprises: an arcuate segment having forward and rear ends spaced from the wall of said bore and on the inside thereof an inwardly projecting shoulder engaging the annular groove in a contact in the bore, and on the outside thereof, means for pivotally mounting to said insert the arcuate segment in each bore so that either end of said arcuate segment may be deflected whereby, a tool may be inserted into a bore in said insert to engage and pivot said arcuate segment in said bore thereby releasing a contact in said bore for removal from the connector.
Claim 5
Dependent Claim
190 words
In combination with an electrical connector having removable contacts, said connector of the type having a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an annular groove between said forward and rear portions; an insert having a plurality of bores each having a rear portion of a respective contact therein; and means for releasably mounting said contacts in a respective bore, said means including a plurality of contact retaining members in each of said bores, the improvement wherein each of said contact retaining members comprises: an arcuate segment having forward and rear ends spaced from the wall of said bore and on the inside thereof an inwardly projecting shoulder engaging the annular groove in a contact in the bore, and on the outside thereof, means for pivotally mounting to said insert the arcuate segment in each bore so that either end of said arcuate segment may be deflected whereby, a tool may be inserted into a bore in said insert to engage and pivot said arcuate segment in said bore thereby releasing a contact in said bore for removal from the connector.
Claim 6
Dependent Claim
59 words
The electrical connector recited in claim 3 wherein said means for pivotally mounting each of said contact retention members is a radially extending connecting member located between the ends of the segments and integral with the outside of said arcuate segment at one end and integral at the other end with the wall of the bore in the insert.
Claim 7
Dependent Claim
20 words
The electrical connector recited in claim 3 wherein said connecting member is axially displaced from said shoulder of said segment.
Claim 8
Dependent Claim
178 words
In combination with an electrical connector having removable contacts said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an annular groove between said forward and rear portions, and means for releasably mounting said contacts in said housing including an insert having a plurality of bores therein, each bore having therein a portion of a respective contact having the annular groove therein and a plurality of contact retention members in each bore, the improvement wherein: each of said retention members having forward and rear free ends spaced from the wall of said bore and on the inside thereof an inwardly projecting shoulder engaging the annular groove in a respective contact; and means for pivotally mounting said contact retention members in a respective bore of said insert so that either free end of said retention members may be deflected whereby, a tool may be inserted into a bore to engage and pivot said members thereby releasing a contact in the bore for removal from the connector.
Claim 9
Dependent Claim
