The invention discloses a high voltage interlocking contactor structure for high voltage battery PACK cabinet bodies. The high voltage interlocking contactor structure for the high voltage battery PACK cabinet bodies comprises the high voltage battery PACK cabinet bodies and high voltage interlocking contactors, wherein the high voltage interlocking contactors are arranged in the PACK cabinet bodies. The high voltage battery PACK cabinet bodies comprise the first PACK cabinet bodies and the second PACK cabinet bodies, and an external circuit is arranged between the first PACK cabinet bodies and the second PACK cabinet bodies. According to the high voltage interlocking contactor structure for the high voltage battery PACK cabinet bodies, each high voltage interlocking contactor with an auxiliary contact is additionally arranged into each individual high voltage battery PACK cabinet in order to control the positive electrode of a high voltage output connected with the cabinet; when the contactors cannot pull-in, a positive terminal cannot connect with the positive electrode of a internal battery, so that a power-off state of the whole cabinet is guaranteed, and safety of the battery device and operators is protected.
