Abstract
Abstract A two-part connector assembly wherein the elements are latched together by a latch on one element which latches to a notch on the other element. The latch, in cross-section, is T-shaped. To release, pressure is applied to one arm of the T to rock it about the shank of the T, which is integral with the casing. The contacts are rear-clip insertion and extraction types, with the tines for contact retention integral with the inside of the bore in which the contact is located.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
217 words
An electrical connector assembly comprising: a one-piece unitary body of insulation material having a plurality of passages extending therethrough from a front face to a rear face; an electrical contact positioned axially in each of said passages, each said contact being insertable from the rear of said body into its corresponding passage and having an enlarged section defining a rearwardly facing shoulder; means within each said passage limiting movement of the respective contact therein toward the front end of said passage; stop means associated with each said passage engageable with said rearwardly facing shoulder for limiting rearward movement of said contact when said contact is in the most forward position in said passage permitted by said movement limiting means; said stop means for each said passage comprising a part of said unitary body extending rearwardly from said rear face to circumferentially spaced locations about said passage; and said part being resiliently radially expandable to permit said contact enlarged section to pass therethrough upon forward insertion of the contact into said passage, said part contracting behind said contact rearwardly facing shoulder when said contact is in said forward position, and said contact being removable from the passage from the rear of said body by expanding said part sufficiently to permit said contact enlarged section to pass rearwardly therethrough.
Claim 2
Dependent Claim

An electrical connector assembly comprising: a one-piece unitary body of insulation material having a plurality of passages extending therethrough from a front face to a rear face; an electrical contact positioned axially in each of said passages, each said contact being insertable from the rear of said body into its corresponding passage and having an enlarged section defining a rearwardly facing shoulder; means within each said passage limiting movement of the respective contact therein toward the front end of said passage; stop means associated with each said passage engageable with said rearwardly facing shoulder for limiting rearward movement of said contact when said contact is in the most forward position in said passage permitted by said movement limiting means; said stop means for each said passage comprising a part of said unitary body extending rearwardly from said rear face to circumferentially spaced locations about said passage; and said part being resiliently radially expandable to permit said contact enlarged section to pass therethrough upon forward insertion of the contact into said passage, said part contracting behind said contact rearwardly facing shoulder when said contact is in said forward position, and said contact being removable from the passage from the rear of said body by expanding said part sufficiently to permit said contact enlarged section to pass rearwardly therethrough.
Claim 3
Dependent Claim
38 words
A connector assembly as set forth in claim 1 wherein: the inner surface of the rear section of said part flares outwardly to provide an entrance ramp for insertion of the contact into the passage from the rear.
Claim 4
Dependent Claim
38 words
A connector assembly as set forth in claim 1 wherein: each said contact has a rear section behind said enlarged section extending rearwardly from said rear face of said body; and said part engages said contact rear section.
Claim 5
Dependent Claim
19 words
A connector assembly as set forth in claim 1 wherein: said part comprises a plurality of circumferentially spaced tines.
Claim 6
Dependent Claim
43 words
A connector assembly as set forth in claim 1 wherein: each said contact enlarged section comprises a collar defining a forwardly facing shoulder; and said movemEnt limiting means comprises a rearwardly facing shoulder in each passage engageable by said contact forwardly facing shoulder.
Claim 7
Dependent Claim
33 words
A connector assembly as set forth in claim 1 including: a resilient grommet adjacent to said rear face of said body having passages therethrough in axial alignment with said passages in said body.
Claim 8
Dependent Claim
30 words
A connector assembly as set forth in claim 1 wherein: said part is formed with a forwardly facing shoulder engageable with said rearwardly facing shoulder of said contact enlarged section.
Claim 9
Dependent Claim
35 words
A connector assembly as set forth in claim 7 wherein: the inner surface of the section of said part forward of said forwardly facing shoulder thereon forms a continuation of the wall of said passage.
