Abstract
The noise received by the unused connectors limits the accuracy of a device for measuring the leakage from a piece of electronic medical equipment. To reduce noise the device is surrounded by a Faraday shield which encloses unused connectors of the device. The shielded connector includes a post having a transverse hole near its distal end. A coil spring surrounds the post end and is connected to the Faraday shield of the device. An insulated retainer prevents the distal end of the coil spring from extending beyond the end of the post. The retainer is compressed against the coil spring to expose the transverse hole when a lead is to be attached to the connector.
