Abstract: A receiver designed to receive and engage an interchangeable test adapter (ITA) such that electrical contacts carried by the ITA and receiver are releasably engaged. The receiver includes sliding cam plates driven by a lever assembly and adjacent sliding hanger structures that are retractable. The sliding hanger structures are biased to extend forwardly, and are mounted within hanger slide retaining structures that define forward stops. When an ITA is to be engaged with the receiver, roller pins of the ITA are placed in the hangers such that they also extend into the adjacent sliding cam plates. When the user actuates the lever, the cam plates force the ITA to move inwardly, into engagement. The motion of the cam plates also forces the hanger structures to slide inwardly, such that they are flush with the face of the receiver.

Abstract: An electronic equipment enclosure includes a card cage for holding a plurality of electronic instrumentation circuit cards. Interface adapters are mounted on the front panels of each of the circuit cards to provide external connections to respective ones of the circuit cards through a connector module at the front end of each interface adapter. A pair of positioning pins are mounted on the front of each interface adapter on opposite sides of the respective connector module. A receiver is hinged to the front of the enclosure and includes upper and lower frames having a series of holes therethrough in correspondence with respective ones of the alignment pins. When the receiver is placed in an upright closed position, the alignment pins engage respective ones of the holes to accurately position the front of each adapter module and corresponding connector module which extend into a module access space between the frames.
