Abstract
Abstract An electrical connector is provided for use with a circuit card which has a generally planar substrate having multiple conductive elements disposed along at least one edge thereof. Each of the conductive elements is coupled to an electrically conductive trace on the surface of the planar substrate, and at least one conductive cover panel is provided which may be mounted to the planar substrate. An electrical coupling which includes multiple electrical contacts for external connection to the circuit card is provided, and each of the multiple electrical contacts is then coupled to an associated electrical terminal, such as a solder tail, which may then be mated to one of the multiple conductive elements on the planar substrate. A grounding clip is then mounted on at least one of the associated electrical terminals. The grounding clip includes a conductive member which extends outward from the electrical terminal to engage the generally planar conductive cover panel while the conductive cover panel is mounted above the substrate such that at least one electrically conductive trace on the planar substrate is electrically coupled through a conductive element, the electrical coupling and the grounding clip to the conductive cover panel. In this manner, a conductive trace within the circuit card may be simultaneously grounded through the external electrical contacts of the coupling and to the conductive cover panel, minimizing the possible discharge of an electrical charge and preventing electromagnetic emissions by the circuit card.
