[0027] In order to make the technical solution and technical effect of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments.

[0028] The utility model aims to provide a three-phase terminal block for solving Figure 1 The radial arrangement of the three-phase terminal blocks causes the Y-dimension of the motor to increase, resulting in a relative increase in cost.

[0029] refer to Figure 2-3 , mainly includes a terminal block body 10, an end cover 20 and a motor 30, wherein the terminal block body 10 is built into the accommodating space of the end cover 20 and is fixed to the motor 30.

[0030] Furthermore, the end cover 20 with the built-in terminal block body 10 is axially arranged on the end face of the motor 30, which significantly reduces the Y-direction size of the drive motor and facilitates the layout of the entire vehicle.

[0031] refer to Figure 4 The terminal block body 10 is a circular structure, and the terminal block body 10 is embedded and fixed on the two opposite inner side walls of the end cover 20. The terminal block body 10 is provided with a stud 11, a slot 12 and a threaded hole 13. Specifically:

[0032] The studs 11 are injection-molded at intervals on the surface of the terminal block body 10, and the studs 11 are fastened with three-phase copper noses and copper terminals of the high-voltage busbar. Furthermore, three studs 11 are arranged at equal intervals along the width direction of the end cover 20. Generally speaking, the spacing between the studs 11 only needs to meet the creepage distance. The three-phase copper noses are fastened to the corresponding three studs 11 by nuts; at the same time, the copper terminals of the high-voltage busbar can also be fixed to the studs 11 by nuts. Compared with the existing design in which the copper terminals of the high-voltage busbar are fixed to the three-phase terminal block with screws, the process of this embodiment is simpler, and the structure is simple and orderly.

[0033] The slot 12 can be used to hold a low-voltage connector. Preferably, the slot 12 is in a straight line and parallel to the wide side of the end cap 20. Compared to existing designs that use cable ties and cable tie screw holes to secure low-voltage connectors, the slot 12 design in this embodiment simplifies the process and significantly reduces operating time.

[0034] The threaded holes 13 are used with screws to fix the terminal block body 10 to the end cover 20. Preferably, four threaded holes 13 are provided in this embodiment.

[0035] A motor, wherein the end face of the motor 30 is provided with an end cover 20, and the above-mentioned terminal block body 10 is installed in the accommodating space of the end cover 20 also falls within the protection scope of the present utility model.

[0036] The end cap 20 is a rectangular structure, axially arranged on the end face of the motor 30. Three high-voltage busbar interfaces 21 are spaced apart on the sidewall of the end cap 20, away from the slot 12. The motor winding leads 14 connect to the copper terminals of the high-voltage busbar on the studs 11 and are led out of the corresponding high-voltage busbar interfaces 21, making the entire lead structure fixed, orderly, simple, and compact.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
