Positioning structure for PCB and upper insulation support

Abstract

The invention discloses a positioning structure for a PCB and an upper insulation support, and belongs to the technical field of brushless motors. The positioning structure comprises the PCB and the upper insulation support, the upper surface of the upper insulation support is provided with a plurality of positioning benches, the top surfaces of the positioning benches are h higher than the top surfaces of terminal fixing seats, the top surface of each positioning bench is provided with a guide positioning column matched with a positioning hole and a fixing hole matched with an installing hole, one end of the guide positioning column, matched with the positioning hole, is a tapered structure, and a sidewall of each positioning bench is provided with a wire-passing groove for limiting a conducting wire. According to the positioning structure, in the assembling process of the PCB and the upper insulation support, the guide positioning column and the positioning holes are matched so that accurate positioning between terminals of the upper insulation support and terminal connection holes of the PCB can be realized, the quantity of defective products in the automatic generation can be reduced, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of brushless motors, in particular to a positioning structure for a PCB board and an upper insulating support. Background technique [0002] A brushless motor is a motor without brushes and commutators (or collector rings), which operates by changing the alternating frequency and waveform of the current wave that passes into its stator winding coil. Brushless motors are widely used by major manufacturers because of their high efficiency, low energy consumption, low noise, long life, high reliability, servo control, stepless frequency conversion speed regulation, relatively low cost and ease of use. [0003] The existing brushless motor mainly includes: a housing, a printed circuit board ("PCB" for short), a rotor, and a stator. The stator includes: an upper insulating support, a stator core, a lower insulating support, and a stator winding. The upper insulating bracket and the lower insulating bracket are r...

Problems solved by technology

[0005] In the production process of the existing brushless motor, one is to fix the PCB board on the housing first, and then assemble the PCB board and the upper insulating bracket through the terminal connection holes on the PCB board and the terminals on the upper insulating bracket. At the same time, in the actual production of this assembly method, due to the large error in the relative position between the terminal connection hole on the PCB board and the terminal on the upper insulating bracket, defective products are prone to appear in the automated production process; another It is to install the PCB board on the upper insulating bracket first, and then directly weld the wires of the stator winding to the PCB board. In actual production, this assembly method needs to manually solder the wires of the stator winding to the PCB board. Therefore, it is difficult Automate
