Once the plug is fully inserted within the port, the electrostatic discharge element does not electrically contact the plug or the port pins and therefore has substantially no affect on the normal connection between the port and the plug.

Abstract: A chassis utilizes spring fingers having contact portions and mid portions where each spring finger forms multiple cantilevers to provide different spring constants. Accordingly, the increase in force resulting from displacement can be better controlled and even minimized for certain ranges of displacement. In particular, each spring finger can be configured to perform in an operating range characterized by a smaller spring constant. As a result, the force increase in this operating range is slower thus accommodating circuit boards with large connector height variations without significantly changing the normal contact force. Such operation enables the chassis to consistently pass EMI and ESD testing, as well as provide more reliable device operation.

Abstract: A high voltage connector assembly is disclosed for use with high power apparatus including x-ray devices. The present connector is a pancake-style connector, and interconnects a high voltage cable with the cathode of the x-ray tube. The present connector includes a housing, a socket assembly, and insulating material surrounding the socket assembly to insulate it from the housing.
