ABSTRACT:
A receptacle fixture for equipment units each having a housing containing plug-in component assemblies characterized by the fixture comprising a pair of spaced, elongated spars forming a cable chute and having a contact strip with a first group of wrapping posts protruding from a surface thereof for forming connections with central office and ring wiring and having a bracket-like mounting assembly for each of the equipment units spaced along the spars. The mounting assemblies include guide rails for receiving the housing of the equipment unit and fastening means for attaching the housing on the fixture. Each housing has a printed circuit board provided with internal wiring for the equipment unit disposed on the side of the housing adjacent the contact strip with the printed circuit board having openings for receiving the wrapping posts of the contact strip so that they will protrude into the interior of the housing. In addition, each printed circuit board is provided on an inner surface with a group of contact blades which are in electrical communication to the printed conductors of the circuit board and each of the plug-in assemblies has an elongated spring contact strip for forming electrical contacts with the wrapping posts of the contact strip and the additional contact blades as the component is plugged into the housing of the equipment unit. Preferably, the contact strip is provided with longitudinally spaced, traversely extending slots to facilitate guiding wires for wrapping on the wrapping posts of the contact strip and the strip is provided with additionally spaced slots to enable tying cables containing the wires on a surface opposite the surface from which the wrapping posts extend.
