[0002] During the assembly and manufacturing process of a display, there is a step in the lighting test of the backlight bar of the display's backlight module. The specific operation is to connect the metal fingers of the backlight bar to electricity. Since the gold fingers of the backlight bar are extended separately, when performing the lighting test on the backlight bar of the backlight module, the tester needs to hold the conductive part to touch the gold fingers, or use the gold fingers to touch the conductive part. Such operation has certain safety hazards. Moreover, during the test process, the tester's operating behavior is not standardized, which will also affect the test efficiency. Utility Model Content
