Crimping device and testing system
This utility model relates to a crimping device and a testing system. The crimping device is used to crimp copper busbars onto the terminals of a module under test. It includes: a substrate capable of moving up and down relative to the module under test; and multiple crimping components disposed on the substrate and arranged corresponding to the terminals of the module under test. Each crimping component includes a crimping member and a first elastic member. The crimping member is located at the bottom of the substrate and is capable of moving up and down relative to the substrate. The two ends of the first elastic member abut against the substrate and the corresponding crimping member, respectively. The crimping member can crimp the copper busbars onto the corresponding terminals of the module under test, enabling simultaneous testing of multiple terminals of the module under test. The first elastic member can absorb planar errors and act as a buffer, solving the problem of poor contact between the crimping member, the copper busbar, and the terminals. This ensures that the copper busbars are crimped smoothly and firmly onto each terminal, avoiding safety hazards such as localized high temperatures, oxidation, or even melting. This improves the compatibility and testing stability of the crimping device.
