[0002] Motors are widely used in modern household appliances. For example, as an important component of compressors, they play an important role in refrigerators, air conditioners, freezers, heat pump water heaters and other refrigeration or heating appliances, affecting the power and effect of refrigeration or heating. In the current motor design and manufacturing technology, insulating brackets are conventional application components, most of which are made of PBT or PPS materials with smooth surfaces. During the winding process, the enameled wire will slide in its winding position, causing a large difference between the set winding parameters and the actual arrangement, which in turn causes uneven arrangement of the enameled wire in the entire slot. In addition, the winding speed is fast and the tension is large, which can easily damage the paint film of the enameled wire at the corners, resulting in a decrease in the winding quality of the motor. Therefore, there is an urgent need for an insulating bracket to solve the above problems. Summary of the invention

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1 to 5 As shown, the present invention provides an insulating bracket, including a skeleton 1, a winding frame 2 and a winding protective wall 3. The skeleton 1 is annular in structure, and a plurality of winding frames 2 are evenly arranged along the circumference of the skeleton 1. A gap for allowing the enameled wire to pass is provided between two adjacent winding frames 2. The winding frame 2 is provided with an anti-skid platform 21. The top surface of the anti-skid platform 21 is arranged at an angle with the horizontal direction. The top surface of the anti-skid platform 21 is provided with a wavy anti-skid groove 22. The anti-skid groove 22 is used to fix the position of the enameled wire so that the enameled wire can be stably arranged and distributed, improve the winding state of the enameled wire, and reduce the risk of paint damage to the enameled wire. At the same time, the winding protective wall 3 is arranged on the inner ring of the skeleton 1, and the winding protective wall 3 is connected to the winding frame 2. The winding protective wall 3 is used to prevent the enameled wire from detaching from the winding frame 2. The winding protective wall can release the space inside the skeleton, which is more conducive to the distribution of the enameled wire and high slot full rate models, and effectively controls the arrangement space of the enameled wire.

[0040] Exemplarily, the width of the anti-skid groove 22 is less than or equal to 1 / 2 of the width D of the anti-skid platform 21, and / or the length of the anti-skid groove 22 is less than or equal to 1 / 2 of the length L of the anti-skid platform 21. Under the condition of ensuring the stable arrangement of the enameled wire, the strength of the anti-skid platform 21 and the winding frame 2 is ensured to avoid the winding frame 2 from breaking during the winding process, thereby producing defective products. Specifically, the position of the anti-skid groove 22 on the winding frame 2 is the starting position of the winding frame 2 in a clockwise or counterclockwise direction according to the winding direction, ensuring that the enameled wire first contacts the anti-skid groove 22 when winding through the winding frame 2, so that the enameled wire can be stably arranged and the risk of paint damage is reduced.

[0041] Furthermore, the angle α between the top surface of the anti-slip platform 21 and the horizontal direction satisfies 0°<α≤45°, which reduces the pressure and friction of the enameled wire on the corner of the winding part of the winding frame 2, thereby improving the winding state of the enameled wire. At the same time, the circumference of the enameled wire is reduced, and the usage of the enameled wire is reduced, thereby reducing production costs.

[0042] Exemplarily, the cross section of the anti-skid groove 22 is a tooth-shaped structure. Specifically, the tooth top h of the anti-skid groove 22 satisfies 0.5 mm ≤ h ≤ 2 mm, and the tooth width d of the anti-skid groove 22 satisfies 0.5 mm ≤ d ≤ 5 mm, ensuring that the anti-skid groove 22 can stably fix the position of the enameled wire while reducing the risk of paint damage. In addition, controlling the depth and width of the anti-skid groove 22 is conducive to controlling the strength of the winding frame 2 and avoiding damage to the winding frame 2 during the winding process.

[0043] like Figure 3 As shown, the height of the top of the anti-slip platform 21 is H1, the height of the lowest point of the top surface is H2, δ=H1-H2, and the difference δ between the highest point and the lowest point of the top surface of the anti-slip platform 21 satisfies 0mm<δ≤15mm. By controlling the slope and height of the anti-slip platform 21, the winding angle and circumference of the enameled wire can be effectively controlled, and the winding circumference of the enameled wire can be reduced while ensuring that the risk of paint damage is reduced.

[0044] Exemplarily, the winding guard wall 3 is provided with an observation opening 31, and the observation opening 31 is used to observe the wiring state of the enameled wire. In this embodiment, the observation opening 31 is an inverted triangle shape, and the top width D1 of the observation opening 31 is equivalent to the width D of the anti-slip platform 21. During the winding process of the enameled wire, as the number of winding coils of the enameled wire increases, the probability of poor wiring increases. The observation opening 31 can effectively observe and check the wiring state of the enameled wire.

[0045] On the other hand, the present invention also provides a motor, which includes an insulating bracket. The motor is used to drive a compressor. The motor includes a stator. The insulating bracket is arranged at both ends of the stator. The insulating bracket is used to fix the enameled wire winding. The insulating bracket with stable and uniform enameled wire arrangement can effectively improve the winding quality of the stator, thereby improving the insulation performance and stability of the motor to meet the higher use requirements of the compressor.

[0046] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
