Abstract

Abstract A contact retention clip is provided with a B-stage epoxy resin coating. The clip is installed in the contact cavity of a plastic body under heat and pressure to cause the coating to form its final resin. The resin becomes impregnated into the wall of the cavity to seal micro cracks in the wall which otherwise may lead to voltage breakdowns.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 72 words
A method of making an electrical connector assembly comprising the steps of: providing a plastic body having a bore therein; providing a contact retention clip having a resinous coating thereon, said plastic body and resinous coating have a chemical substituent in common; inserting said clip in said bore; and heating said coating on said clip to cause any cracks which may exist in said plastic body to become sealed by the coating.
Claim 2
Independent Claim 72 words
A method of making an electrical connector assembly comprising the steps of: providing a plastic body having a bore therein; providing a contact retention clip having a resinous coating thereon, said plastic body and resinous coating have a chemical substituent in common; inserting said clip in said bore; and heating said coating on said clip to cause any cracks which may exist in said plastic body to become sealed by the coating.
Claim 3
Dependent Claim 15 words
The method according to claim 1 wherein: said coating is heated by heating said clip.
Claim 4
Dependent Claim 56 words
The method according to claim 2 wherein: said clip is provided with a plurality of discontinuities therearound; the portion of said plastic body surrounding said bore is softened by the heating of said clip; and said clip is expanded in said bore while heated to cause said discontinuities to be seized by said softened body portion.
Claim 5
Dependent Claim 15 words
The method according to claim 1 wherein: said chemical substituent is a sulfur containing radical.
Claim 6
Dependent Claim 14 words
The method according to claim 1 wherein: said resinous coating is an epoxy resin.
Claim 7
Dependent Claim 23 words
The method according to claim 5 wherein: said plastic body is a polyethersulfone; and said epoxy resin is a sulfone modified epoxy system.
Claim 8
Dependent Claim 17 words
The method according to claim 1 wherein: said coating on said clip is a B-stage epoxy resin.
Claim 9
Dependent Claim 24 words
The method according to claim 1 wherein: said plastic body is a polyethersulfone; and said resinous coating is a B-stage sulfone modified epoxy system.
Claim 10
Dependent Claim 51 words
A contact retention clip adapted to be mounted in a bore in a plastic body comprising: a hollow metallic body having an inwardly extending resilient contact retention tine thereon; and a resinous coating on said metallic body containing a chemical substituent in common with a chemical constituent in the plastic body.
Claim 11
Dependent Claim 51 words
A contact retention clip adapted to be mounted in a bore in a plastic body comprising: a hollow metallic body having an inwardly extending resilient contact retention tine thereon; and a resinous coating on said metallic body containing a chemical substituent in common with a chemical constituent in the plastic body.
