[0002] With the development of economy and science and technology, the application of electronic products in industrial production is becoming more and more extensive. In the processing and production of electronic products, electrical testing machines are often needed to test the electrical performance of electronic products, such as conductivity test, voltage resistance test, impedance test, etc. When automatic electrical testing machines test electronic products, they need to place the electronic products on electrical testing fixtures. In order to prevent the electronic products from moving, they will be clamped and fixed. Currently, most clamping and fixing methods use electric telescopic rods to drive the clamping plates to move and clamp the electronic products. When facing electronic products of different sizes, the travel of the electric telescopic rod is not convenient to control, so that the clamping plates will cause excessive pressure on the sides of the electronic products, which can easily damage the electronic products. Therefore, we propose an electrical testing fixture for automatic electrical testing machines. Utility Model Content
