Abstract
A quick stacking translator fixture for a printed circuit board tester has a pattern of test probes on a base upon which the translator fixture is mounted. The translator fixture comprises a plurality of essentially parallel and vertically spaced apart rigid translator plates having selected patterns of aligned holes for positioning translator pins for contacting test points on a printed circuit board supported at one end of the translator fixture. The translator pins translate electrical test signals between the test points on the printed circuit board and the test probes on the base of the tester. The translator fixture includes a plurality of translator plate stacking towers of identical construction supporting the translator plates in their fixed positions in the translator fixture. Each stacking tower comprises a rigid support member formed as an integral piece having vertically spaced apart translator plate support surfaces with corresponding recessed upright alignment posts at spaced apart levels of the stacking tower. The translator plate support surfaces and their corresponding alignment posts having respective diameters at each level which are progressively shorter along the length of the tower to define a stair-step arrangement. The translator plates are assembled onto the stacking towers at predetermined levels in a progressive stacking sequence, so that each translator plate is supported by a corresponding translator plate support surface and retained thereon in a fixed position by engagement with the related alignment post.
