[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] A wiring structure for a motor, such as Figs. 1 to 4 As shown, it includes a plastic encapsulated body 1 with stator windings inside and a cover 3, and a lead box 2 is provided on the plastic encapsulated body 1.

[0021] Specifically, the encapsulation body 1 has a receiving groove 5 for accommodating the lead box 2. The wires on the stator winding are led out from the receiving groove 5. The receiving groove 5 is adapted to the lead box 2, so that the encapsulation body 1 and the lead box 2 can remain relatively stable, which facilitates the installation of the lead box 2.

[0022] Further, the side wall of the lead box 2 is provided with positioning protrusions 6. There are two positioning protrusions 6, and they are respectively arranged on the two side walls of the lead box 2. The side wall of the receiving groove 5 is provided with positioning grooves 7. There are two positioning grooves 7, and they are respectively located on the two side walls of the receiving groove 5. The positioning protrusions 6 and the positioning grooves 7 are adapted to each other and correspond to each other. The positioning protrusions 6 are inserted into the positioning grooves 7. The cooperation of the positioning grooves 7 and the positioning protrusions 6 can further ensure the stability of the lead box 2, and according to the relative position relationship between the positioning grooves 7 and the positioning protrusions 6, the installation of the lead box 2 is more convenient and fast.

[0023] The wires on the stator winding are led out into the lead box 2. The wires are used to connect to the circuit board. The wires are folded and placed in the lead box 2 to make full use of the internal space of the lead box 2. By folding the wires, the lead box 2 can accommodate longer wires to the greatest extent, and avoid the wires from being entangled due to being too messy.

[0024] The lead box 2 is detachably provided with a cover 3. Specifically, the cover 3 is covered on the lead box 2. The cover 3 seals the opening of the lead box 2, so as to realize the protection of the wires by the cooperation of the lead box 2 and the cover 3.

[0025] Specifically, an installation hole 8 is opened in the lead box 2, and an installation protrusion 9 is provided on the end surface of the cover 3. The installation protrusion 9 is inserted into the installation hole 8. Through the cooperation of the installation protrusion 9 and the installation hole 8, the lead box 2 and the cover 3 are kept relatively stable, and further ensure the effective protection of the wires by the cooperation of the lead box 2 and the cover 3.

[0026] A wire passing hole 4 for the wires to pass through is opened at the bottom of the lead box 2. The wire passing hole 4 can limit the wires and ensure the stability of the wires.

[0027] Both the lead box 2 and the cover 3 are made of plastic material. First, since plastic is an insulating material, using plastic material can avoid conduction and thus improve safety. Moreover, the performance of plastic material is stable and the cost is low, which can extend the service life and reduce the production cost.

[0028] The plastic sealing body 1, the lead box 2 and the cover 3 are integrally plastic-sealed. It should be noted that the plastic sealing body 1, the lead box 2 and the cover 3 are plastic-sealed. Through plastic sealing, it can be ensured that the gaps are completely filled, and the three can be kept relatively stable, and can effectively resist the vibration and impact of the external environment. It should be noted that after the three are plastic-sealed, the cover 3 needs to be removed so that the wires in the lead box 2 can be connected to the circuit board. And the cover 3 is plastic-sealed together with the plastic sealing body 1 and the lead box, because the cover 3 covers the opening of the lead box 2, avoiding the direct contact between the plastic sealing material and the wires during the plastic sealing process and preventing the wires from being damaged.

[0029] The working principle of the present utility model is as follows:

[0030] Firstly, the lead wire is directly drawn from the stator winding and passed through the threading hole 4 of the lead wire box 2, then the positioning protrusion 6 on the lead wire box 2 is aligned with the positioning slot 7, and the lead wire box 2 is placed into the accommodating slot 5, at this time the positioning protrusion 6 is inserted into the positioning slot 7, then the lead wire is folded and accommodated in the lead wire box 2, then the mounting protrusion 9 on the cover 3 is aligned with the mounting hole 8 in the lead wire box 2, and the cover 3 is covered on the lead wire box 2, at this time the mounting protrusion 9 is inserted into the mounting hole 8, then the plastic package body 1, the lead wire box 2 and the cover 3 are integrally plastic packaged, finally the cover 3 is removed, and the lead wire in the lead wire box 2 can be directly connected with the circuit board.

[0031] It should be noted that in the motor wiring process of the prior art, the lead wire is wound around the plug pin of the plastic frame, then the lead wire is flattened, then welding is performed, after the welding is completed, a stand is added to further reinforce the connection between the lead wire and the plug pin, and finally the circuit board is connected by the lead-out winding column.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
