Technical Field
[0001] The utility model relates to the technical field of large current test equipment, in particular to a large current test terminal. Background Art
[0002] At present, the crocodile clips and other test clamps (clamps) that come with the wiring equipment for large current test items (DC resistance or contact resistance) are directly clamped on the lead-out part of the test product. Due to the large test current, for some test products without obvious lead-out parts, the contact between the test clamp and the test product is easy to be insufficient, resulting in overheating of the contact point (surface), increasing measurement errors, and reducing test accuracy.
[0003] For some test products, the test clamp cannot be firmly and reliably clamped on the lead-out part of the test product. Due to the weight of the test line itself, the test clamp is very easy to fall off, which poses a certain safety risk.
