Abstract
An electrostatic discharge protection device is disclosed for use with a printed circuit board (hereafter referred to as 'PCB') of the type having a major portion and a dependent integral tongue having oppositely disposed PCB surfaces with conductor pads disposed thereon. The electrostatic discharge protection device comprises a first hinge structure and a second hinge structure mounted to corresponding PCB surfaces. Each hinge structure has a base section securely mounted to the PCB surface, an elongated arm section pivotally connected to the base section and having an electrically conductive bar disposed along the length thereof, and means for urging the electrically conductive bar against and into electrical interconnection with the conductor pads while the PCB remains disconnected from a complementary edge connector. The PCB's subsequent mating with the edge connector operates to pivot the arm section away from the base section so as to electrically and physically disengage the electrically conductive bar from the conductor pads.
