Abstract: PURPOSE: To sustain electrical contact through an appropriate insertion lock mechanism even in the case of undue vibration by providing first and second means for aligning a draw-out connector in the plane of rear wall in the horizontal and vertical directions, and a third means for locking the connector with respect to a tunnel. CONSTITUTION: A tunnel is defined by two side walls 10, 11 arranged vertically, a top plate 12 and a bottom plate 13. A rear cover 14 is fixed with a circuit card 15 by means of rivets and a connector 16 is fixed to the circuit card 15. A vertical member 17 coupled with the bottom plate 13 is provided with at least two rearward positioning pins 18 and at least two forward positioning pins 19. The pin 18 meshes the positioning hole of the circuit card 15 which is thereby positioned correctly with respect to the pin 19. The pin 19 positions the drawer 20 with respect to the circuit card 15 in the horizontal and vertical directions.

Abstract: An electronic equipment drawer is aligned with an electrical connector in a tunnel in the horizontal and vertical directions with alignment pins and holes. A screw drive and cam mounted on the drawer engages a tunnel wall and controls insertion into the tunnel to provide proper electrical contact and lock the drawer in place in the tunnel. A bus extender card inserted in a connector centrally located on a mother board is supported by surfaces on a bar extending between end walls of the drawer. The end walls include pairs of channels on opposed walls which support feature cards inserted into connectors mounted on the bus extender card.
