Apparatus and method for inserting, retaining and extracting printed circuit boards

摘要

An apparatus and method for inserting and extracting printed circuit boards from a housing using screwing devices. A connector on the printed circuit board includes two tapped holes that cooperate with two threaded shafts held by the housing. The threaded shafts are operatively coupled to a common control shaft in such a way that rotating the control shaft in turn rotates the threaded shafts. Depending upon the rotation direction, the threaded shafts either screw or unscrew within the tapped holes so that the printed circuit board coupled to the connector is inserted or extracted.
