Abstract
Abstract An electrical connector for providing a leakproof releasable electrical connection through a wall even over a wide temperature range. The connector has at least one terminal with the terminal including a ceramic annulus having a sleeve secured at one end that is secured to a base of the connector and a cap secured on the other end with a closed tube to which the electrical connection is made extending through the annulus and being secured to the cap.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
207 words
An electrical connector for providing a hermetically sealed leakproof electrical connection through a wall over a wide temperature range comprising a tubular shell secured to the wall to have an interior end portion located on one side of the wall and an open exterior end portion on the other side of the wall, a base closing the interior end portion of the shell and having at least one hole, a terminal secured to the base at the hole to project into the shell, said terminal including an electrically insulating ceramic annulus having a through hole, means securing one end portion of the annulus to the base, a cap welded to the other end portion of the annulus to form a sealed securement, a tube extending through the through hole of the annulus and the cap, means welding said tube only to the cap and the through hole of the annulus to form a sealed securement, means for securing a conducting wire in the tube, and in which the means securing the annulus to the base and the cap are formed of electrical conducting material and in which they are spaced apart on the annulus to provide an electrically insulating gap therebetween on the periphery of the annulus.

Claim 3
Dependent Claim
96 words
The invention as defined in claim 1 in which there are a plurality of terminals spaced about and connected to the base, and in which a spacer formed of electrically insulating material is located within the shell to abut against the interior of the shell interiorly of the base and beyond the cap of each terminal to provide mechanical support for the terminals by having an aperture through which a portion of the tube of each terminal extends with said aperture for each terminal being smaller than the bottom of the cap of its associated terminal.
