Electrical connector substantially shielded against EMP and EMI energy

摘要

This invention is directed to an electrical connector having substantial shielding effectiveness against EMI energy and especially against EMP energy. The invention improves on known EMI shielded connectors by adding a conductive spring washer, such as a wave washer made from beryllium copper alloy. The spring washer is seated in the plug portion of the connector so as to make electrical contact with the receptacle portion when the plug and the receptacle are mated.
