Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet synchronous motor outlet plate structure, and in particular to a novel portable permanent magnet synchronous motor outlet plate structure. Background Art

[0002] At present, the output wires of permanent magnet synchronous motors are mostly designed by designing terminal board assemblies, which are integrated by injection molding of copper bars and plastic parts, and the motor winding lead wires are resistance welded with the U-shaped clamps of the terminal board assembly, and the motor windings are led out from the inside to the outside through three-phase or six-phase PINs. There is also a layered structure designed for the output board and the GND terminal board to ensure that the GND terminal board is connected to the insulating skeleton, and then the insulating skeleton is connected to the output wire row through hot melt welding, so as to directly pull out the winding lead wires. For the former, there are 5 sets of molds for the U, V, and W three-phase terminal boards, and the number of molds for complex six-phase redundant motors is as high as 9 sets. The mold costs are relatively high. The latter is very complicated in processing technology, which is not conducive to fully automated production lines. Both are not conducive to cost reduction of permanent magnet synchronous motors. In response to the above problems, an effective solution has not yet been found at home and abroad.

[0003] The Chinese utility model patent with announcement number CN207652194U discloses a steel plate shell motor wire outlet structure. This device is provided with a wire outlet hole on the motor casing, and an opening is provided at the end of the wire outlet hole. When fixing the cable, the wire clamp and the cable are pressed in with a caliper. After pressing in, the caliper is released, and the cable naturally rebounds. The wire clamp is squeezed by the internal and external forces of the casing and the cable, so that the cable can be firmly locked to improve production efficiency. In addition, this device protects the cable leading out of the casing by providing a wire sleeve to prevent the cable from being damaged during fixing and use, thereby improving safety performance.

[0005] In view of the problems existing in the above technologies, the utility model proposes a novel and convenient permanent magnet synchronous motor lead-out board structure.

[0006] The utility model aims at solving the above technical problems and adopts the following technical solutions: a novel portable permanent magnet synchronous motor outlet board structure, comprising an insulating frame, on which an outlet row is arranged, on which two groups of GND terminal blocks are arranged, the outlet row is connected to the insulating frame by a hook, and the GND terminal blocks are injection molded on the outlet row after processing.

[0007] Furthermore, the insulating skeleton is provided in multiple groups, and the multiple groups of insulating skeletons are arranged in a circle.

[0008] Furthermore, the insulating skeletons are all provided with stator cores and windings, and the number of the stator cores and windings is the same as the number of the insulating skeletons.

[0009] Furthermore, the outlet line row includes an outlet base, protrusions are arranged on both sides of the outlet base, and a plurality of groups of protruding columns are arranged on the protruding plate of the outlet base.

[0010] Furthermore, a plurality of mounting frames are arranged on the side of the outlet base, and the mounting frames are connected to the insulating frame.

[0011] Furthermore, a plurality of groups of plug-in rods are arranged at the lower end of the protrusion on the outlet base, and the plug-in rods are inserted into the insulating frame.

[0012] Furthermore, the two groups of GND terminal blocks are mirror-imaged on the outlet base.

[0013] The beneficial effects of the utility model compared with the prior art are as follows: compared with the traditional outlet structure and the layered structure of the outlet board and the GND terminal board, the outlet structure using the new outlet row and the GND terminal board reduces expensive mold costs and process steps, and reduces production costs. The outlet structure in which the outlet board and the GND terminal board are matched reduces process complexity, improves the efficiency of whole machine assembly, and reduces waste, which is beneficial for reducing environmental burden, improving sustainability, and meeting regulatory requirements in some industries. The structure of integrating the outlet board and the GND terminal board reduces the assembly complexity of the whole machine, makes assembly faster and more efficient, improves overall manufacturing efficiency, shortens production cycle, and reduces the number of connection points and components, which helps reduce the risk of malfunctions and failures. The integrated structure can reduce potential connection problems and improve product reliability and stability. Through integrated design, it can be more easily adapted to motors of different models or specifications, which provides greater design flexibility and makes it easier to respond to market changes and customer needs.
