U.S. Patents 4,449,778 and 4,501,459 describe a data connector consisting of a plastic enclosure encasing a metal container. The metal container provides electromagnetic shielding for signals passing through the connector. This article provides an alternative shielding technique whereby the plastic enclosure is treated with an electroless deposit of copper over nickel and grounded to the stranded shield of a signal-carrying cable. The design provides acceptable shielding without the need for the metal container. Data connectors which are treated with the disclosed technique are able to transmit data at 16 megabits without violating shielding requirements of the Federal Communications Commission. An electroless plating of copper followed by nickel is deposited on the inside and outside walls of the plastic enclosure.
