[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] Specific embodiment 1: Please refer to Figures 1 to 6 , a terminal box electrical testing fixture of this embodiment includes a base 1, a test table 3 is provided above the base 1, the base 1 includes a top plate 101 and two support plates 102, the support plates 102 are vertically fixed on the left and right sides of the top plate 101, the test table 3 is on the top plate 101, and quick clamps 2 are respectively installed on the left and right ends of the test table 3 to press down and fix the terminal box 8 placed on the test table 3. The test table 3 is a rectangular structure, and elastic positioning columns 4 are respectively installed at the four end corners of the test table 3. The elastic positioning columns 4 are plugged into the terminal box 8, and the terminal box 8 is pressed against There should be mounting holes and elastic positioning columns 4 for plugging and positioning. The test bench 3 includes several raised support blocks 5, and elastic probes 6 are installed on the support blocks 5 to contact the terminal openings on the terminal box 8. One side of the base 1 is provided with several terminal posts 7. In this application, the terminal posts 7 are arranged in two rows, upper and lower. The bottom ends of the elastic probes 6 are respectively connected to the corresponding terminal posts 7 and electrically conductive. The rear ends of the terminal posts 7 are connected to the elastic probes 6 through conductive wires and are electrically conductive. The other end of the terminal post 7 is connected to the control equipment through another cable for data acquisition.
