[0010] The one end of the female end terminal away from the male end terminal is connected with the first wire rod.

[0011] The one end of the male end terminal away from the female end terminal is connected with the second wire rod.

[0012] The first fence is arranged on the female end positioning piece.

[0013] The second fence is arranged on the male end positioning piece.

[0014] Compared with the prior art, the utility model has the advantages that the utility model includes six signal turning needles and three power turning needles, and cooperates six signal turning holes and three power turning holes, can satisfy the use requirement of motor and multiple pin signals simultaneously, and satisfies the use of power line. Through setting fence, it is more convenient to plug. The female end positioning piece is connected with the nut through the thread, and the mutual matching mode when tightening is not only simple and convenient when using plug-in, but also greatly improves the mutual matching effect when locking. The utility model effectively isolates the power end and signal end, and the phenomenon of unstable electric connection and data transmission is basically eliminated. Since the nut and the thread are used in cooperation, during use, only need to tighten after mutual matching, so that the internal sealing ring is fully extruded, to ensure the waterproof effect of IP67 level.
