The male connector 4 is provided with a third guide structure 41 that is inserted into the first guide structure 34 and a fourth guide structure 42 that is inserted into the second guide structure 35. The male connector 4 and the female connector 3 are connected to the BMS (Battery Management System) through a high-voltage interlocking part 36. The male connector 4 and the female connector 3 are provided with electrical connection parts. The structures at both ends of the female connector 3, namely the first end 32 and the second end 33, are symmetrically arranged. In addition, the structures of the male connector 4 on the opposite end faces of the first battery box 1 and the second battery box 2 are also symmetrically arranged. The connection between the two battery boxes is realized through the intermediate female connector 3.

[0028] The bidirectional blind-mating connector of this utility model adopts a bidirectional blind-mating mode. It moves the male connectors of the first and second battery boxes toward the female connector fixed in the middle. Secondly, it replaces the power harness and low-voltage communication harness in the prior art by setting the female connector. In addition, it sets a mutually cooperating guide structure to ensure that blind mating can be successfully achieved. Finally, it sets a high-voltage interlocking part to cut off the high-voltage circuit and ensure the safety of high-voltage connection.

[0029] In this embodiment, as Figure 5 As shown, a groove 311 is provided on the side end of the main body 31 of the female connector. The fixing plate 5 is inserted into the groove 311. The female connector 3 and the fixing plate 5 are detachably connected together by four bolts.
