Abstract

An electrical connection system including a triaxial socket and a triaxial plug, each having three concentric contacts—an inner, an intermediate and an outer contact. In the process of connecting, the outer contacts connect first, the inner contacts connect second, and the intermediate contacts connect third. All contacts except the plug inner contact are connected to an insulator that covers one radial side of the contact, and extends past and over the end of the contact. Two of the insulators isolate the inner contacts from the intermediate contacts prior to either of their connections being made.
