Description

Technical Field

[0001] The invention relates to the technical field of motor stators, in particular to a stator winding bracket. Background Art

[0002] There are two existing motor stator production processes: with a winding bracket and without a winding bracket. The former has the following problems: 1. The production cost of multi-gear products is high; 2. The original product size is changed, which affects the installation and use of the motor and is not very versatile; 3. The welding efficiency of the enameled wire and the stator lead is low; the latter has the following problems: 1. The creepage distance is difficult to control; 2. The stator lead needs to be fixed with a sleeve and a binding tape, which has low production efficiency and difficult quality control; in addition, during the production of these two production processes, the enameled wire needs to pass through the mold of the winding equipment to enter the stator. During the winding process, the mold of the winding equipment does not provide adequate protection for the stator and the enameled wire, and the processes after winding can only be operated manually, which has low production efficiency and difficult quality control.

[0003] Therefore, the prior art needs to be improved and enhanced. Summary of the invention

[0004] In order to overcome the above technical problems existing in the prior art, an object of the present invention is to provide a stator winding bracket which improves product quality and production efficiency.

[0005] The present invention achieves the above-mentioned purpose through the following technical means:

[0006] The cam is an arc-shaped part, and the two ends of the lower horizontal part are connected along the arc direction to form an upper winding space. The upper winding space is formed between the upper extension part and the upper arc part, and the upper protrusion is provided with two connecting terminals. The upper and lower ends of the lower horizontal part are connected to the arc-shaped part by the upper extension part.

[0007] As a further solution of the present invention, an upper embedded portion extends downward from the outer end edge of the upper horizontal portion.

[0008] As a further solution of the present invention, a lower embedded portion extends upward from the outer end edge of the lower horizontal portion.

[0009] Compared with the prior art, the present invention is characterized in that:

[0010] 1. After installing the wire rack, it will not affect the appearance size of the motor, nor will it affect the use and installation of the motor, and it has strong versatility;

[0011] 2. After using the wire rack, the creepage distance of the stator can 100% meet the requirements and is not affected by equipment and other processes;

[0012] 3. Prevent defective products caused by deformation of slot paper during winding process;

[0013] 4. When winding the stator, the wire rack replaces the winding mold in the traditional process, effectively reducing the damage of the enameled wire and enhancing the electrical insulation performance;

[0014] 5. The wire rack can effectively fix the stator lead wire and realize the fully automatic production of the subsequent process;

[0015] 6. It can solve the influence of traditional stator dipping insulating paint on lead wires and inserts;

[0016] 7. Simplify the process, reduce the steps of inserting casing, tying straps and cutting straps in traditional process, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
