Abstract
A strain relief bulkhead that provides EMI shielding for data cables being inserted into cabinets, including a conductive vise, slidably mounted on a stationary guide track that is permanently attached to a bracket made of conductive material to which a conductive cover panel is removably fastened. In a preferred embodiment the vise is moved along the guide track by a threaded screw which extends through threaded openings in the guide track. A C-ring holds the end of the screw to the vise. The bracket containing the vise and guide track is fastened to the cabinet which houses the printed circuit boards by screws or other means. The vise is located on the guide track and the guide track is attached to the bracket in such a way as to provide cable openings through which cables can be inserted. As cables are inserted they are held in place, after fastening the cover panel to the bracket, by sliding the vise to hold the cables against the walls of the bracket, the vise, and the cover panel, thus grounding the cables for EMI shielding and providing strain relief.
