Abstract
An electrical connector is plugged onto an electrical device that has a hollow sleeve and an annular bonnet that has an outer electrical contact ring. The electrical connector includes an annular insulator, a lower elastomeric seal ring, a combination seal and contact member, a shielded conductor to carry an electrical signal out of the electrical connector and a flanged metal guard ring. The combination seal and contact member has a non-conductive elastomeric annulus and a conductive elastomeric portion that are co-molded to provide a unitary annular part. The annulus has a flanged upper end that is bonded to the flanged guard ring and a thinner lower end that has a plurality of axially spaced circumferential flexible sealing lips that biasingly engage the bonnet above the outer electrical contact ring. The conductive elastomeric portion is made of a non-conductive elastomeric material that has conductive particles widely dispersed throughout the material so that the conductive elastomeric portion exhibits a high electrical resistance in the uncompressed state that diminishes when the elastomeric portion is compressed by the outer electrical contact ring of the bonnet so that the …
