Abstract All insulation is removed from a preselected length of the center conductor at one end of a short piece of coaxial cable. An adjacent portion of the outer jacket is also removed and the corresponding sheath folded back upon itself. A tubular contactor is crimped over the exposed conductor and preformed at the outer end to plug onto a device terminal to complete an electrical circuit connection. An insulating tube is placed over the contactor and extends beyond its outer end to recess the circuit connection. Over this tube is placed a metallic ferrule which is positioned even with the insulating tube at the outer end and extends to overlap the undisturbed portion of the cable jacket. The ferrule is welded to a ground plate associated with the terminal and also soldered to the folded back sheath to complete an electrical shield for the circuit connection formed by the contactor and terminal.
A method of completing a shielded circuit connection from a coaxial cable lead to any one of a plurality of terminals on a device terminal board with an associated grounding plate, including the steps of: (a) removing all insulation from a selected length of the center conductor at one end of said coaxial cable, (b) removing the outer jacket covering the adjacent portion of the coaxial cable sheath and folding the exposed sheath back on itself, (c) crimping a fitted contactor to the exposed center conductor, (d) fitting an insulation tube over said contactor when secured to said central conductor, (e) welding or soldering to said grounding plate, so as to enclose said one terminal, a conductive ferrule having a diameter to fit over said insulation tube when in place over said contactor and having a length to also cover said exposed sheath and fit onto the cable jacket beyond, (f) completing a circuit connection by inserting the covered contactor and insulation tube inside said ferrule to couple said contactor to said one terminal, and (g) soldering said ferrule to said exposed cable sheath to complete the circuit connection shield between said grounding plate and cable sheath and to hold said contactor and insulation tube in place.
