[0028] The parallel wiring terminal 6 provided by the utility model adopts a wiring harness 3 connection end and a fixed connection end 65 extending in different directions. The fixed connection end 65 is connected to the external component 4. The two wiring harnesses 3 are respectively connected to the wiring harness 3 connection ends, so that efficient connection of the two wiring harnesses 3 can be achieved. The wiring operation is simple and convenient, and it is also beneficial to reduce the production cost.

[0029] In some embodiments, Figures 1 to 4As shown, the angles between the fixed connection end 65 and the two wiring harness terminals 62 are equal, and the angle between the fixed connection end 65 and the wiring harness terminal 62 is greater than the angle between the two wiring harness terminals 62. In this embodiment, the angles between the fixed connection ends 65 and the wiring harness terminals 62 in three directions are not evenly distributed, but the angle between the two wiring harness terminals 62 is slightly smaller, which can reduce the space occupied by the paralleling terminal 6, reflecting the concept of intensive design.

[0030] Optionally, the fixed connection end 65 and the wiring harness terminal 62 are arranged in a "human" shape to form the parallel wiring terminal 6, and a positioning hole 63 is provided at the center of the intersection of the fixed connection end 65 and the wiring harness terminal 62 to facilitate the snap-fitting with the elastic claw 11 on the protective shell to achieve the fixation of the parallel wiring terminal 6 and the terminal protective shell; the fixed connection end 65 is provided with a mounting hole 61 to facilitate the connection between the parallel wiring terminal 6 and the motor controller.

[0031] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0032] Based on the same inventive concept, the present application also provides a terminal protection shell, such as Figures 1 to 7 As shown, it includes a protective shell body 1 and a protective cover 2 covered on the protective shell body 1, and the parallel terminal 6 is fixed between the protective shell body 1 and the protective cover 2; wherein the protective shell body 1 has a harness protection end 16 for limiting the harness connection terminal 62 and a fixed protection end 13 for limiting the fixed connection end, and the protective cover 2 has a first covering end 21 that is clamped with the harness protection end 16 and a second covering end 22 that is clamped with the fixed protection end 13.
