Abstract
Abstract A high temperature hermetic electrical connector is disclosed in which socket contacts are hermetically sealed in a rear insulator of one connector member. A "napkin" spring is mounted on a forward portion of the body of each socket contact which extends forwardly of the rear insulator. A front insulator is removably mounted on the front face of the rear insulator, and serves to retain the "napkin" springs on the socket contact bodies. When the front insulator is removed, a damaged "napkin" spring may be replaced in the field by a new spring without affecting the sealing integrity of the connector. In a second embodiment, a metal hood slidably mounted on a contact body removably retains the "napkin" spring thereon.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
257 words
An electrical connector member comprising: a shell containing a front insulator and a rear insulator, said shell having a forward end and a rear; said rear insulator having a bore extending from a front face to a rear face thereof; said front insulator being removably mounted in said shell adjacent to the front face of said rear insulator and having a passage therethrough aligned with said bore; releasable holding means adjacent to said forward end of said shell for holding said front insulator adjacent to said rear insulator, said holding means being movable relative to said shell to allow removal of said front insulator from said shell; a socket contact including a contact body permanently mounted in said bore, said contact body embodying a forward portion extending forwardly of said front face into said passage, said forward portion having a longitudinally extending open curved channel therein adapted to slidably receive a mating pin contact; pin contact-receiving spring sleeve means removably mounted on said forward portion of said contact body adapted to resiliently urge the pin contact against the wall of said channel, said spring sleeve means being loose relative to the wall of said passage surrounding said sleeve; and said front insulator embodying means for retaining said spring sleeve means on said forward portion of said contact body when said front insulator is mounted in said shell adjacent to said front face of said rear insulator, said spring sleeve means being longitudinally slidably removable from said contact body when said front insulator is removed from said shell.
Claim 2
Dependent Claim
257 words
An electrical connector member comprising: a shell containing a front insulator and a rear insulator, said shell having a forward end and a rear; said rear insulator having a bore extending from a front face to a rear face thereof; said front insulator being removably mounted in said shell adjacent to the front face of said rear insulator and having a passage therethrough aligned with said bore; releasable holding means adjacent to said forward end of said shell for holding said front insulator adjacent to said rear insulator, said holding means being movable relative to said shell to allow removal of said front insulator from said shell; a socket contact including a contact body permanently mounted in said bore, said contact body embodying a forward portion extending forwardly of said front face into said passage, said forward portion having a longitudinally extending open curved channel therein adapted to slidably receive a mating pin contact; pin contact-receiving spring sleeve means removably mounted on said forward portion of said contact body adapted to resiliently urge the pin contact against the wall of said channel, said spring sleeve means being loose relative to the wall of said passage surrounding said sleeve; and said front insulator embodying means for retaining said spring sleeve means on said forward portion of said contact body when said front insulator is mounted in said shell adjacent to said front face of said rear insulator, said spring sleeve means being longitudinally slidably removable from said contact body when said front insulator is removed from said shell.
