Patent ID: 6877431

Claim:
A hermetically sealed electrical feed-through device comprising an electrically conductive body ( 11 ) with an oval or elliptical through-going opening (O), said electrically conductive body having a front side and a rear side and a center of said oval or elliptical through-going opening (O) at least approximately coincides with a center of said electrically conductive body ( 11 ); an electrically conductive angular or bent isolated pin ( 13 ) hermetically sealed centrally in said oval or elliptical through-going circular opening (O) by means of a glass seal ( 17 ), so that said angular or bent isolated pin ( 13 ) projects outward from said rear side of said electrically conductive body and so that one end of the angular or bent isolated pin is accessible from or exposed on said front side of said electrically conductive body ( 11 ); and an electrically conductive angular or bent ground pin ( 15 ) connected with the rear side of the electrically conductive body ( 11 ) adjacent to said oval or elliptical through-going opening, said electrically conductive angular or bent ground pin ( 15 ) having a substantially identical shape as said angular or bent isolated pin ( 13 ) and projecting outward from the rear side of the electrically conductive body ( 11 ) approximately parallel to the isolated pin; wherein the oval or elliptical through-going opening (O) has a major axis (a) and a minor axis (b) such that different bridge wires of different lengths are connectable between the front side of the said electrically conductive body ( 11 ) and the one end of the straight isolated pin ( 13 ) accessible from or exposed on the front side of the electrically conductive body ( 11 ).
