Abstract:
1. A positioning apparatus mounted to a chassis of an electronic device for fixing test fixtures in the chassis, the chassis comprising a pair of sidewalls, the positioning apparatus comprising: a pair of fixing members arranged on the sidewalls of the chassis and defining a pair of fixing holes; a first blocking bar adapted to abut the test fixtures and comprising a first extruding tab at one end thereof to engage in one of the fixing holes, a hook formed at the other end thereof, a pair of flanges extending outwardly from opposite side edges, and a threaded hole defined therein; and a second blocking bar slidably attached to the first blocking bar and comprising a second extruding tab engaging in the other one of the fixing holes, a captive screw mounted on the second blocking bar, a pair of wings extending outwardly from opposite side edges, and a slot defined in the second blocking bar for accommodating sliding of the hook of the first blocking bar therein, thereby allowing adjusting of the distance between the first extruding tab and the second extruding tab when the captive screw disengages from the threaded hole; wherein the captive screw extends in a direction substantially perpendicular to a sliding direction of the second blocking bar to engage in the threaded hole, thereby securing the second blocking bar to the first blocking bar; wherein a pair of aligned arced notches is separately defined in the flanges of the first blocking bar and the wings of the second blocking bar to provide an operating space for manipulating the captive screw.
