Abstract
Abstract A contact retaining clip is fixed in an insulator cavity by the use of discontinuities around the clip which can be wedged or embedded in the insulator. Preferably a probe is inserted into the clip to expand it. The clip and/or the probe may be heated prior or during insertion or by heating after insertion of the clip but before expansion of the clip.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
An electrical connector assembly, said assembly comprising: an insulator body having a cavity therein; a longitudinally slit, hollow, resilient contact retention clip in said cavity, said clip having a forwardly and inwardly extending spring tine and a plurality of discontinuities therearound spaced from said tine; said clip being expanded from an initial configuration while in said cavity to snugly fit the outer surface thereof against the wall of said cavity; and said insulator body being thermally deformed at the locations of said discontinuities so as to seize upon said clip thereat and to prevent axial movement of said clip in said cavity.
Claim 2
Dependent Claim
102 words
An electrical connector assembly, said assembly comprising: an insulator body having a cavity therein; a longitudinally slit, hollow, resilient contact retention clip in said cavity, said clip having a forwardly and inwardly extending spring tine and a plurality of discontinuities therearound spaced from said tine; said clip being expanded from an initial configuration while in said cavity to snugly fit the outer surface thereof against the wall of said cavity; and said insulator body being thermally deformed at the locations of said discontinuities so as to seize upon said clip thereat and to prevent axial movement of said clip in said cavity.
Claim 3
Dependent Claim
143 words
An electrical connector assembly, said assembly comprising: an insulator body having front and rear faces; a bore in said insulator body opening at said rear face and extending at least part way into said insulator body; said bore having a central axis; a longitudinally slit, cylindrical, resilient contact retention clip expanded from an initial configuration while in said bore to snugly fit against the wall of said bore, said clip having at least one spring tine extending from a position near said rear face forwardly toward said front face and toward said bore axis, said clip having a plurality of outwardly extending barbs therearound; and said insulator body being thermally deformed at said barbs so as to seize upon said clip thereat and to prevent movement of said clip in said bore, said barbs being fully embedded in the wall of said bore.
Claim 4
Dependent Claim
143 words
An electrical connector assembly, said assembly comprising: an insulator body having front and rear faces; a bore in said insulator body opening at said rear face and extending at least part way into said insulator body; said bore having a central axis; a longitudinally slit, cylindrical, resilient contact retention clip expanded from an initial configuration while in said bore to snugly fit against the wall of said bore, said clip having at least one spring tine extending from a position near said rear face forwardly toward said front face and toward said bore axis, said clip having a plurality of outwardly extending barbs therearound; and said insulator body being thermally deformed at said barbs so as to seize upon said clip thereat and to prevent movement of said clip in said bore, said barbs being fully embedded in the wall of said bore.
Claim 5
Dependent Claim
14 words
The invention as defined in claim 2 wherein: said insulator body is thermally deformable.
Claim 6
Dependent Claim
16 words
The invention as defined in claim 3 wherein: said insulator body is a one-piece molded body.
Claim 7
Dependent Claim
29 words
The invention as defined in claim 2 wherein: said barbs are struck out of the wall of said clip and extend radially outwardly into the wall of said bore.
Claim 8
Dependent Claim
33 words
The invention as defined in claim 5 wherein: apertures extend through the wall of said clip where said barbs are struck out; and the material of said insulator body extends into said apertures.
Claim 9
Dependent Claim
17 words
The invention as defined in claim 2 wherein: said barbs embody radially extending rearwardly facing shoulders thereon.
Claim 10
Dependent Claim
16 words
The invention as defined in claim 2 wherein: said barbs are spaced behind said spring tine.
Claim 11
Dependent Claim
144 words
An electrical connector assembly, said assembly comprising: an insulator body having front and rear faces; a bore in said insulator body opening at said rear face and extending at least part way into said insulator body; said bore having a central axis; a longitudinally slit, cylindrical resilient contact retention clip expanded from an initial configuration while in said bore to snugly fit against the wall of said bore, said clip having at least one spring tine extending from a position near said rear face forwardly toward said front face and toward said bore axis, said clip having a plurality of apertures therearound spaced behind said tine; and said insulator body being thermally deformed at said apertures whereby the material of said body extends into said apertures so as to seize upon said clip thereat and to prevent movement of said clip in said bore.
Claim 12
Dependent Claim
144 words
An electrical connector assembly, said assembly comprising: an insulator body having front and rear faces; a bore in said insulator body opening at said rear face and extending at least part way into said insulator body; said bore having a central axis; a longitudinally slit, cylindrical resilient contact retention clip expanded from an initial configuration while in said bore to snugly fit against the wall of said bore, said clip having at least one spring tine extending from a position near said rear face forwardly toward said front face and toward said bore axis, said clip having a plurality of apertures therearound spaced behind said tine; and said insulator body being thermally deformed at said apertures whereby the material of said body extends into said apertures so as to seize upon said clip thereat and to prevent movement of said clip in said bore.
