The invention relates to an insertion/extraction tool for inserting and extracting printed circuit boards from a card cage. The invention uses fewer parts than the prior art and reduces bending stress on the printed circuit board by simultaneously applying the insertion or extraction force to both sides of the plane of the printed circuit board.

[ What is claimed is:] [1.] A system for inserting and extracting a printed circuit board from a chassis comprising:a printed circuit board with a pair of opposing flat surfaces for attaching electrical components;said printed circuit board containing a hole near a front corner and a notch on the edge adjacent the front corner, wherein said notch is further from the front corner than said hole; andan insertion/extraction tool comprisinga handle portion pivotally secured to said printed circuit board overlying only one of the pair of opposing flat surfaces of said printed circuit board so that space is available on the other of the pair of opposing flat surfaces of said printed circuit board for electrical components;a lower body portion including toe and heel sections integrally connected to the handle portion and contoured such that the toe section disengages the chassis during extraction of said printed circuit board and engages the chassis during insertion of said printed circuit board and the heel section engages the chassis during extraction of said printed circuit board and disengages the chassis during insertion of said printed circuit board;an upper body portion including lower toe and heel sections connected to the lower body portion at the toe and heel sections such that a slot between the upper and lower body portions is created for receiving said printed circuit board, said upper body contoured such that the upper toe section disengages the chassis during extraction of said printed circuit board and engages the chassis during insertion of said printed circuit board and the upper heel section engages the chassis during extraction of said printed circuit board and disengages the chassis during insertion of said printed circuit board; anda pivot means connecting the upper body portion to the lower body portion, said pivot means being able to penetrate said printed circuit board so that, when the insertion/extraction tool is attached to said printed circuit board, said upper and lower body portions of the insertion/extraction tool overlie both sides of said printed circuit board and provide support on both sides of said printed circuit board during insertion and extraction.
