Description

Technical Field

[0001] The utility model relates to the technical field of synchronous motor wiring board structures, in particular to a novel high-efficiency permanent magnet synchronous motor wiring board component structure. Background Art

[0002] At present, the outlet structure of the six-phase redundant permanent magnet synchronous motor is mostly an integrated structure of a six-phase terminal board and a plastic terminal board. This outlet structure is suitable for motors with a small number of parallel branches and is easy to implement in terms of technology. However, if the number of parallel branches of the motor increases, the six-phase terminal board and the GND terminal board are arranged due to insufficient spacing, so a layered structure of the six-phase terminal board and the GND terminal board is adopted. This structure also increases the difficulty of terminal welding in the process, greatly affecting the efficiency of the motor assembly and increasing the cost. The terminal board needs to be plastic-coated to insulate and protect the terminal board from bending and deformation. With the layering of the six-phase terminal board and the GND terminal board, the position of the GND terminal board terminal cannot be accurately guaranteed in terms of technology, which ultimately results in a large error between the position of the GND terminal board terminal and the design requirements, and cannot meet the motor design requirements. The six-phase redundant motor with a layered structure has a mold number of up to 9 sets, and the mold cost is high, which is not conducive to the 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] A Chinese invention patent with publication number CN110855047A discloses a motor wiring structure and a fixing assembly having the same. This device avoids the problem of a large span of the terminal block due to the large distance between multi-phase enameled wires by setting up a special winding skeleton, and reduces the span between the terminal blocks to a certain extent. However, this device has a high manufacturing cost, and the distance between the six-phase PIN components is short, which is prone to interference between parts. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the problems existing in the above technologies, the utility model proposes a novel high-efficiency permanent magnet synchronous motor terminal board component structure.

[0006] The utility model aims at solving the above technical problems and adopts the following technical solutions: a novel high-efficiency permanent magnet synchronous motor terminal board component structure, comprising an insulating frame, a mounting frame being arranged on the insulating frame, the mounting frame comprising a mounting seat, two groups of mounting grooves 1, 2 and 3 being arranged on the mounting seat, a plurality of groups of terminal boards being arranged on the mounting seat, and the terminal boards being fixedly connected to the insulating frame by hooks.

[0007] Furthermore, the terminal block includes a U-phase terminal block 2 and a U-phase terminal block 1 installed on the installation slot 3, and the U-phase terminal block 2 and the U-phase terminal block 1 are arranged at opposite positions on the installation seat.

[0008] Furthermore, the terminal block includes a V-phase terminal block 2 and a V-phase terminal block 1 installed on the second mounting groove, and the V-phase terminal block 2 and the V-phase terminal block 1 are arranged at opposite positions on the mounting seat.

[0009] Furthermore, the terminal block includes a W-phase terminal block 2 and a W-phase terminal block 1 installed on a mounting groove 1, and the W-phase terminal block 2 and the W-phase terminal block 1 are arranged at opposite positions on the mounting seat.

[0010] Furthermore, a center point wiring board 2 and a center point wiring board 1 are arranged in the mounting seat, and the center point wiring board 2 corresponds to the U-phase wiring board 1, the V-phase wiring board 1, and the W-phase wiring board 1.

[0011] Furthermore, the central point terminal block 1 corresponds to the W phase terminal block 2, the V phase terminal block 2, and the U phase terminal block 2.

[0012] Furthermore, the central point terminal block 2 and the central point terminal block 1 are made of copper and are injection molded onto the mounting frame after processing.

[0013] Furthermore, the W-phase terminal board 2, V-phase terminal board 2, U-phase terminal board 2, U-phase terminal board 1, V-phase terminal board 1, and W-phase terminal board 1 are all processed separately and then injection molded onto the mounting frame.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the split type uses 9 sets of molds, while the integrated type uses only 5 sets of molds. Expensive mold costs are reduced, production costs are reduced, and the six-phase terminal board and the plastic terminal board are integrally injection molded. This structure not only increases the distance between the six-phase PIN components when designing and wiring the motor, avoiding interference between the components, but also reduces the complexity of winding and terminal welding in the process, improves work efficiency, and has good processability. Due to the reduction of connecting parts, the overall structure is more solid, reducing the possibility of failure and looseness, thereby improving the reliability and stability of the product, and making it easier to maintain and repair, because the overall structure is clear, reducing the difficulty of disassembly and installation, and helping to reduce maintenance cycles and downtime.
