ABSTRACT:
A housing for printed circuit cards or modular assemblies that provides for easy access to the cards or assemblies as well as to interconnection buses and other equipment mounted in the housing is disclosed. The housing includes a cabinet having two fixed, substantially flat plates. The housing further includes a chassis having two substantially rectangular rotating plates. Each fixed plate of the cabinet has a rotating plate of the chassis connected to one side of it by means of two removable hinge pins such that the axis extending from the front to the back of the rotating plate extends perpendicular to the axis extending from the top to the bottom of the fixed plate when both hinge pins are in place. Orientation of the pins is such that by removing one pin, the rotating plate is rotatable about the other pin with respect to the fixed plate. The rectangular rotating plates are connected together by a system of bars forming the chassis on which printed circuit cards and other equipment can be mounted. By using bars of different lengths, any number of cards or assemblies can be accommodated.
