Current compressor motors typically use slot insulation and slot wedges to ensure insulation and withstand voltage, with slot insulation playing the most significant role. However, during motor winding, slot insulation often shifts vertically, causing it to become entangled in the windings and thus fail to provide insulation and withstand voltage.

[0003] Therefore, there is an urgent need for an insulating support to solve the above-mentioned technical problems. Utility Model Content

[0030] like Figures 1 to 5 As shown, this utility model provides an insulating bracket. The insulating bracket includes an insulating ring 1, a plurality of tooth roots 2, and a plurality of buckles 3.

[0031] Specifically, several tooth roots 2 are spaced apart at one end along the circumference of the insulating ring 1 on the inner circumference of the insulating ring 1, and two tooth tips 21 are protruding at the other end along the circumference of the insulating ring 1, so that a first slot 4 is formed between two adjacent tooth roots 2. Several buckles 3 are correspondingly arranged with several tooth tips 21, and the buckles 3 are set on the tooth tips 21. The slot insulation can be set in the first slot 4 so that the buckles 3 abut against the slot insulation. Compared with the prior art, the slot insulation is set in the first slot 4 and is locked by the buckles 3, which can prevent the slot insulation from moving up and down during the motor winding process, avoid the slot insulation from being rolled into the winding, and ensure the normal operation of the slot insulation.

[0032] Optionally, the side of the buckle 3 near the inner circumference of the insulating ring 1 is an arc-shaped edge 34, and the center of the arc-shaped edge 34 is concentric with the center of the insulating ring 1, so that the dimensions of the first slots 4 are all the same, thereby ensuring that the slot insulation can be smoothly engaged in the first slot 4 and preventing the slot insulation from loosening.

[0033] Optionally, the insulating support further includes a plurality of fixing posts 5, which are spaced apart along the circumference of the insulating ring 1 at different tooth roots 2. Specifically, in this embodiment, the insulating support is provided with four fixing posts 5, which are arranged along the circumference of the insulating ring 1 at different tooth roots 2. The insulating support is connected to the motor housing through the fixing posts 5, which can improve the stability of the insulating support and thus improve the stability of the slot insulation. Of course, in some other embodiments, the number of fixing posts 5 is determined according to the actual situation, which will not be elaborated here.

[0034] Optionally, the insulating support further includes a plurality of second slots 6, which are spaced apart along the circumference of the insulating ring 1 on the outer periphery of the insulating ring 1. Specifically, the plurality of second slots 6 are arranged in a circular array, wherein m rows are arranged along the circumference of the insulating ring 1 and n columns are arranged along the radial direction of the insulating ring 1, where m and n are both integers greater than 1. The second slots 6 are used to fix the wires and prevent the wires from moving or falling off.

[0035] Optionally, the distance between the two latches 3 in the first slot 4 is A, where 5mm ≥ A ≥ 2.5mm. Specifically, a distance A ≥ 2.5mm between the two latches 3 allows the winding machine to enter the first slot 4, thereby ensuring that the enameled wire can enter the first slot 4 during the winding process; a distance A ≤ 5mm between the two latches 3 prevents the enameled wire from winding the slot insulation into the winding during the winding process.

[0036] Optionally, the insulating support also includes a plurality of connectors 7, which are arranged one-to-one with a plurality of clips 3, and the connectors 7 are disposed between the clips 3 and the tooth tips 21. Specifically, the two ends of the connectors 7 are fixedly connected to the clips 3 and the tooth tips 21 respectively, which can improve the stability of the clips 3.

[0037] Optionally, the buckle 3 is provided with a first connecting edge 31, a second connecting edge 32, a third connecting edge 33, and an arc-shaped edge 34. The two ends of the first connecting edge 31 are respectively connected to one end of the third connecting edge 33 and the arc-shaped edge 34, and the two ends of the second connecting edge 32 are respectively connected to the other end of the third connecting edge 33 and the arc-shaped edge 34. The first connecting edge 31, the second connecting edge 32, the third connecting edge 33, and the arc-shaped edge 34 are connected to form a trapezoidal structure. The third connecting edge 33 is connected to the connector 7. The length of the first connecting edge 31 is L1, the length of the second connecting edge 32 is L2, and the length of the third connecting edge 33 is L3, wherein L1 < L2 < L3. The arc-shaped edge 34 can resist the groove insulation, thereby improving the stability of the groove insulation.

[0038] Optionally, the distance between the third connecting edge 33 and the tooth tip 21 is B, where 0.8mm ≥ B ≥ 0.25mm. Specifically, a distance of B ≥ 0.25mm between the third connecting edge 33 and the tooth tip 21 allows the buckle 3 to engage with the slot insulation, improving the stability of the slot insulation; a distance of B ≤ 0.8mm between the third connecting edge 33 and the tooth tip 21 prevents the slot insulation from shifting during winding.

[0039] Optionally, the included angle between the second connecting edge 32 and the third connecting edge 33 is Φ1, where L1≤L2-L3*cos(Φ1); the arc length of the arc edge 34 is C, the radius of the arc edge 34 is R1, and the central angle corresponding to the arc edge 34 is Φ2, where C=R1*Φ2*π / 180, and Φ2≥1°. Specifically, 2mm≥L3≥0.5mm, a first rounded corner 8 with a radius of R3 is provided at the connection between the first connecting edge 31 and the arc-shaped edge 34, the second rounded corner 9 with a radius of R4 is provided at the connection between the second connecting edge 32 and the arc-shaped edge 34, the third rounded corner 10 with a radius of R5 is provided at the connection between the second connecting edge 32 and the third connecting edge 33, and a fourth rounded corner 11 with a radius of R6 is provided at the connection between the first connecting edge 31 and the third connecting edge 33. R3=R4=R5=2R6, which ensures the size and strength of the buckle 3. On the one hand, it prevents the buckle 3 from being too small, resulting in insufficient strength and avoiding breakage of the buckle 3 when inserted into the slot for insulation; on the other hand, it prevents the buckle 3 from being too large, occupying a portion of the slot area and avoiding collision between the enameled wire and the arc-shaped edge 34 during winding, thus preventing breakage of the buckle 3.

[0040] Optionally, an inner ring is formed around the other end of several tooth roots 2, with a radius of R2, where R1-R2≥2.5mm. This prevents the buckle 3 from being too small and thus not strong enough, and avoids the buckle 3 breaking when inserted into the slot for insulation.

[0041] Optionally, the height of the buckle 3 is H, wherein 3.5mm≥H≥0.5mm. A height of H≥0.5mm for the buckle 3 can smoothly hold the slot insulation and prevent the slot insulation from moving up and down. A height of H≤3.5mm for the buckle 3 can prevent the buckle 3 from being too long and thus not having enough strength.

[0042] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
