Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment relates to an electrical short-circuit test fixture, which includes a fixture base 1 and an upper cover 2, wherein the upper cover 2 is fixed on the fixture base 1 by a plurality of middle pad fixing screws 7. Be equipped with middle cushion on tool base 1, then be fixed in tool base 1 with upper cover 2 through middle cushion set screw 7 on, so design so, for convenient upper cover 2 can push down, upper cover 2 can not break away from tool base 1 again simultaneously, makes and fixes through swing joint between the two.

Wherein, tool base 1 one end is equipped with a plurality of contact pins 3, and a plurality of contact pins 3 are fixed in a connector 6, and connector 6 is fixed in tool base 1, and connector 6 is fixed in on tool base 1 through a set screw 10. One end of the upper cover 2, which is far away from the contact pin 3, is provided with a plurality of metal probes 4, and the plurality of metal probes 4 are connected with the contact pin 3 in a matching way through a lead 5. In the design, a background conductive lead is added at a golden finger of a product and is connected with a line of a COM end to form a loop. The metal probes 4 are mainly electrically connected with the gold fingers of the product, and mainly lead out pattern background lines and COM base lines.

After being led out, a plurality of metal probes 4 are connected with the contact pins 3 in a matched mode through the conducting wires 5 one by one, the contact pins 3 integrate the circuits of the metal probes to the connectors 6, the connectors 6 are connected with terminals such as a computer through corresponding data transmission lines, then products of the metal probes are detected, and whether short circuit exists or not is tested.
