Abstract
A receiver includes an inner frame and outer walls. Between the outer walls and adjacent side of the receiver frame are placed fixed hanger plates provided with straight slots and interior slides having coacting cam slots. The slides are driven by a hand lever and attached torsion shaft with connected slotted linkage having an over-dead-center locked position. An individual test adapter has four sets of dual bearings or rollers on common dry lube sleeves and can rotate oppositely during the camming action to minimize friction. The individual test adapter rollers rest on dwell shoulders of the cam slots and then descend through the straight slots during movement of the slides to produce positive straight-on engagement of test adapter and receiver multiple contacts, such as ball detent contacts with paddle contacts. The slides have elongated linear guide bearings with attached dry lube pads for precision free movement. A single pilot pin and opening at one corner of the individual test adapter and receiver eliminates lateral play. The system can be expanded so that the receiver can accept two individual test adapters in tandem or a single large individual test adapter.
