Busbar structure and battery module for thermal runaway test

The utility model relates to a busbar structure and a battery module used for a thermal runaway test, the busbar structure comprises a busbar body and a leading-out wire, the end part of the leading-out wire is connected with an OT terminal, and the OT terminal is detachably connected with the busbar body. According to the utility model, the OT terminal is arranged on the outgoing line, the OT terminal is safely and simply connected with the busbar body through the bolt, and then the busbar body is connected with the positive and negative poles of the battery to be tested, so that positive and negative connection wires can be safely and reliably led out, and stable and reliable triggering of test conditions is ensured; the cost advantage that welding may cause failure of a module or a whole battery pack system and further needs replacement is solved, the one-time passing rate of a test is improved, the cost is reduced to a certain extent, potential safety hazards such as electric sparks existing in welding ar
