Abstract: An electrical connector having inner and outer conductors along with a sleeve. The outer conductor has an inwardly directed annular ridge adapted to interlock with the sleeve. The sleeve is preferably of teflon. In order to maintain contact between the sleeve and the annular ridge of the outer conductor with changes in temperature, the length of the ridge is related to the diameter of the sleeve at each point along the slope of the end slope of the ridge by the equation L=D tan .theta.. The angle related in the equation is the end bevel angle on the ridge and when this angle is on the order of 45.degree., then the relationship reduces to one in which the length of the ridge is comparable to the diameter of the sleeve in order to maintain contact over a temperature change range.

Abstract: An electrical connector having inner and outer conductors along with a sleeve therebetween. The outer conductor has an inwardly directed annular ridge adapted to interlock with an annular recess in the sleeve. In order to maintain contact between the recess of the sleeve and the annular ridge of the outer conductor with changes in temperature, the length of the ridge is related to the diameter of the sleeve at each point along the slope of the beveled wall of the ridge by the equation L=D tan .theta.. In a second version of the invention described herein there is an assymetrical connector in which the opposed beveled end walls of the respective body and sleeve are defined by frusto-conic surfaces of cones each having a common vertex preferably disposed on the connector longitudinal axis.
