Abstract: An equipment module, a module retention device, as well as a system and a method for mounting equipment modules are disclosed. The modules can be installed without tools, using the retention device. Each module includes a chassis unit which slides into a unit rack, which is in turn attached to a mounting frame. The entire assembly may be mounted to an instrument panel. The module retention device is attached to the chassis unit, typically engaging a slot on the rack. A rotating fastener secures the retention device in the engaged position. The method includes inserting an electronic module into the open end of a unit rack, sliding an engagement lug attached to a cam lever into engagement with a slot on the rack, electrically coupling a connector on the module with a connector on the rack, and attaching the rack to the mounting frame.

Abstract: An electronic equipment module includes a symmetrical casting with two chassis units. Each unit includes a mounting recess to receive a circuit assembly, separated by a cover applied to either unit, or both. The module is normally mounted to a unit rack, and typically has a removably attachable, re-orientable keyed surface which mates with another keyed surface on the rack. A mounting system includes a unit rack coupled to at least one electronic equipment module and a mounting frame. A method of mounting an electronic equipment module includes inserting the module into an open end of a unit rack, electrically coupling connectors attached to the module and the rack, securing the module to the rack, and attaching the rack to a mounting frame. The module can be secured to the rack by engaging a cam lever attached to the module.
