Abstract
Abstract A high-temperature electrical connector including interengageable mating sections each having a central and an outer-tubular metallic contact and an insulating sleeve disposed therebetween with the insulating sleeve of the one section having self-lubricating surfaces of a fluorocarbon engaging the sleeve or its associated outer-tubular metallic contact of the other section, the fluorocarbon having a relatively low heat deflection temperature so as to deform at high temperatures. The other insulating sleeve is composed of a material such as an aromatic polysulfone with a relatively high heat deflection temperature to provide a relatively rigid support for the fluorocarbon sleeve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
69 words
The electrical connector of claim 1 wherein each of said sections includes a second metallic contact outwardly disposed about said sleeve as a shield for the central contact with the shield for one of the central contacts including an inward curve to form a spring means for engagement with the shield for the other of said central contacts, and the sleeve of said second section is a thermoplastic polysulfone.
Claim 2
Dependent Claim
23 words
The connector of claim 1 wherein said sleeve with said riser extends longitudinally beyond said central contact and is laterally spaced apart therefrom.
Claim 3
Dependent Claim
29 words
The electrical connector of claim 3 wherein said second sleeve is a plastic sleeve disposed around and spaced apart from said central contact and said plastic is a polysulfone.
Claim 4
Dependent Claim
29 words
The electrical connector of claim 4 wherein said riser extends radially around said mating end for sealing engagement with the mating end of the sleeve of the second section.
Claim 5
Dependent Claim
11 words
The electrical connector of claim 5 wherein said fluorocarbon is polytetrafluoroethylene.
