[0002] Refer to Figure 1 , the wiring cover is an important part of the motor and is used to protect and fix the wires. The motor wiring cover usually includes a box body 1 and a wire pipe 2. A wire passing hole is formed through the side wall of the box body 1. The wire pipe 2 is connected to the box body 1 and communicates with the wire passing hole. The wire passes through the wire passing hole and the wire pipe 2. Among them, the wire pipe 2 plays a guiding and protecting role for the wire and facilitates the subsequent sealing treatment of the wiring cover.

[0003] In the traditional wiring cover, the wire pipe is welded and fixed to the outer wall of the box body. Although it can meet certain usage requirements, it has limitations in terms of sealing performance and structural strength, and the welding process is complex, resulting in low processing efficiency of the wiring cover. Utility Model Content

[0009] By adopting the above technical solutions, under the integral casting production process, the arrangement method of first arranging the wire pipe on the inner wall of the box body can be realized. On the one hand, by reducing the external volume of the wiring cover, the external occupied space of the wiring cover is reduced, which is convenient for the installation of the motor; on the other hand, it is also convenient for the overall processing of the wiring cover.

[0010] Optionally, there are multiple wire passing holes, and there are multiple wire pipes. The multiple wire pipes correspond to the multiple wire passing holes one by one.

After determining the position of the wire, heat the heat-shrinkable tube, and the heat-shrinkable tube shrinks. On the one hand, it further reduces the communication port between the inner cavity of the box body and the outside, which is convenient for subsequent sealing treatment; on the other hand, the shrunk heat-shrinkable tube plays a certain positioning role for the wire, improving the convenience of subsequent processing of the motor.

[0018] Optionally, the length of the heat-shrinkable tube is greater than the length of the wire pipe.

[0019] By adopting the above technical solution, when threading the wire from the inside to the outside, abut the wire against the end of the heat-shrinkable tube, and the heat-shrinkable tube deforms and is poked into the wire pipe; continue to move outward, and finally the heat-shrinkable tube stops moving under the abutting action of the end of the wire pipe away from the side wall of the box body, while the wire smoothly passes through under the guiding action of the outer wall of the heat-shrinkable tube, thereby improving the convenience of the wire threading operation.

[0028] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 drawings.

[0029] Embodiment 1 of the present application discloses a stainless steel motor wiring cover.

[0030] Embodiment 1

[0031] Referring to Figure 1 , a stainless steel motor wiring cover includes a box body 1 and a wire tube 2. A wire passing hole 11 is penetrated through the side wall of the box body 1. The wire tube 2 is arranged on the side wall of the box body 1, and the inner cavity of the wire tube 2 is communicated with the wire passing hole 11. The wire tube 2 and the box body 1 are integrally cast, and both the wire tube 2 and the box body 1 are made of stainless steel.

[0032] In this embodiment, under the production process of integral casting, the wire tube 2 is connected to the inner wall of the box body 1. On the one hand, by reducing the external volume of the wiring cover, the external occupied space of the wiring cover is reduced, facilitating the installation of the motor; on the other hand, it is also convenient for the overall processing of the wiring cover.

[0033] It can be understood that in other embodiments, the wire tube 2 can also be arranged on the outer wall of the box body 1.

[0034] In this embodiment, a plurality of wire passing holes 11 are provided, and a plurality of wire tubes 2 are provided. The plurality of wire tubes 2 correspond to the plurality of wire passing holes 11 one by one, so as to facilitate the wires to pass through from multiple directions and the arrangement of the wires.

[0035] Furthermore, the end face of the wire tube 2 away from the side wall of the box body 1 is arranged in an arc shape to play a certain protective role for the wires and reduce the wear of the wires when threading the wires.

[0036] The implementation principle of Embodiment 1 is as follows: When manufacturing the wiring cover housing, the wire tube 2 made of stainless steel and the box body 1 are integrally formed by casting, which simplifies the production process, reduces the manufacturing cost, enhances the structural strength of the wiring cover housing, improves its impact resistance and vibration resistance, and extends the service life.

[0037] Embodiment 2

[0038] Referring to Figure 2 , the difference between this embodiment and Embodiment 1 is that along the radial direction from the side wall of the box body 1 to the center, the inner diameter of the wire tube 2 gradually decreases. With this design, on the one hand, the communication port between the inner cavity of the box body 1 and the outside is relatively small, which is convenient for subsequent sealing treatment and improves the sealing performance of the motor; on the other hand, it is convenient for demolding during the processing.

[0039] Furthermore, a heat-shrinkable tube 3 is arranged on the circumferential side of the wire tube 2. One end of the heat-shrinkable tube 3 far from the side wall of the box body 1 is closed, and a through hole 31 for the wire to pass through is penetrated through the side wall of the heat-shrinkable tube 3 far from the box body 1. When threading the wire, first pass the wire through the through hole 31, the inner cavity of the wire tube 2 and the inner cavity of the wire tube 2. After determining the position of the wire, heat the heat-shrinkable tube 3, and the heat-shrinkable tube 3 shrinks. On the one hand, it further reduces the communication port between the inner cavity of the box body 1 and the outside, which is convenient for subsequent sealing treatment; on the other hand, the shrunk heat-shrinkable tube 3 plays a certain positioning role for the wire, improving the convenience of subsequent processing of the motor.

[0040] Among them, the heat-shrinkable tube 3 is fixedly bonded to the outer wall of the wire tube 2. In order to enhance the bonding stability between the heat-shrinkable tube 3 and the wire tube 2, the outer wall of the wire tube 2 can be frosted.

[0041] In this embodiment, the length of the heat-shrinkable tube 3 is greater than the length of the wire tube 2. When threading the wire from the inside to the outside, the wire is abutted against the end of the heat-shrinkable tube 3, and the heat-shrinkable tube 3 deforms and is pierced into the wire tube 2; continue to move outward, and finally the heat-shrinkable tube stops moving under the abutting action of the end of the wire tube 2 far from the side wall of the box body 1, while the wire smoothly passes through under the guiding action of the outer wall of the heat-shrinkable tube 3, thereby improving the operation convenience of threading the wire and ensuring that there is enough connection area between the heat-shrinkable tube 3 and the wire tube 2 to ensure the connection stability between the heat-shrinkable tube 3 and the wire tube 2.

[0042] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
