Stator wiring structure and wiring process

Abstract

The invention discloses a stator wiring structure, which comprises a stator iron core. A plurality of winding grooves are uniformly distributed on the stator iron core along the circumferential direction, a winding frame is formed between adjacent winding grooves, coil windings are wound on the winding frames, the corresponding coil windings are connected with leads, a PCB substrate is installed on the stator iron core, the PCB substrate is fixedly connected with the copper sheet used for being welded with the lead, and when the lead is welded with the copper sheet, the PCB substrate has good heat resistance, so that high temperature generated during welding can be prevented from damaging the stator iron core, the product quality is ensured, and automation is realized; meanwhile, the invention further discloses a stator wiring process, when the lead and the copper sheet are welded, the PCB substrate has good heat resistance, so that the stator iron core can be prevented from being damaged by high temperature generated during welding, the product quality is ensured, and the process steps are simple.

Description

【Technical field】 [0001] The invention relates to a motor, in particular to a stator wiring structure and a wiring process. 【Background technique】 [0002] The low-power, low-voltage 120-240V motors currently on the market are composed of a stator assembly and a rotor assembly. The stator assembly is wound with a copper wire winding. After the copper wire winding is wound, it needs to be connected to the outside through the lead wire. Terminal connection, and then the lead wire is wound and fixed on the stator assembly to ensure that the lead wire is firmly connected to the copper wire winding or to the external terminal; today, several lead wires are wound and bundled on the stator assembly at the same time through plastic tape, and on the lead wire The sleeve is provided with a protective sleeve to prevent the lead wires from being damaged; however, the plastic tape is easy to break and age, and there is also a problem of difficulty in connecting the lead wires to the exte...

[0002] The small power and low voltage 120-240V motors currently on the market are composed of a stator assembly and a rotor assembly. The stator assembly is wound with a copper wire winding. After the copper wire winding is wound, it needs to be connected to the outside through the lead wire. Terminal connection, and then the lead wire is wound and fixed on the stator assembly to ensure that the lead wire is firmly connected to the copper wire winding or to the external terminal; today, several lead wires are wound and bundled on the stator assembly at the same time through plastic tape, and on the lead wire The sleeve is equipped with a protective sleeve to prevent the lead wires from being damaged; however, the plastic tape is easy to break and age, and there is also a problem of difficulty in connecting the lead wires to the external terminals. For example, the plastic tape entangles several lead wires together, making it difficult to distinguish

[0003] Nowadays, in order to solve the above-mentioned existing problems, a mounting seat is installed on the stator assembly, and a connecting column welded with the lead wire is fixed on the mounting seat. Because the mounting seat is made of conventional materials, when welding, the welding generated High temperature will lead to deformation of the mounting seat or stator core, resulting in unguaranteed product quality
