Abstract
A printed circuit card having a printed circuit board therein with ground contact pads. The printed circuit card is made of a conductive housing in which the printed circuit board resides. At least one ground contact clip is interfaced with both the ground contact pad on the printed circuit board and the conductive housing to complete a ground circuit for the printed circuit board and for protecting the connector against electromagnetic interference and electrostatic discharge. The ground clip further ensures that the printed circuit card has a high ground-to-signal ratio, thereby ensuring good data transmission through the card.
Claims6
A printed circuit card of the type having a printed circuit board with ground contact pads, input/output connector interfaces, and a housing made of a conductive material to provide an earth ground path for the printed circuit board through the ground contact pads thereon, the improvement comprising a ground contact clip interfaced to the ground contact pads and conductive housing, the ground contact clip further comprising,
- a hingeable base member,
- first and second resilient ground contact pad interfaces extending laterally from the hingeable base member wherein at least the first resilient ground contact pad interface is in electrical contact with one of the ground contact pads;
- and
- first and second resilient housing interfaces formed from the lateral ends of the first and second resilient ground contact pad interfaces, the first and second resilient housing interfaces in electrical contact with the conductive housing for completing the ground path between the ground contact pads and earth.
