Abstract

An electrical jack plug includes an insulating sleeve member disposed over the conductor and ground contact portions of a tip contact member. The sleeve member includes a thin conductive outer sleeve member and an insulating plastic inner sleeve member press fit inside the outer sleeve member. The inner sleeve member has a portion, disposed on the interior thereof, adapted to mate with a complimentary portion of a tip contact member. In assembly, the conductor and ground contacting portions of the tip contact member are surrounded by the insulating inner sleeve member to prevent shorting of such connections. The insulating inner sleeve member has an annular portion extending beyond the conductive outer sleeve member. The inner sleeve member may be comprised of colored plastic to provide a readily visible color coding scheme for interconnections provided by the electrical jack plug.
