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

Abstract

The invention discloses a positioning structure of a PCB board and an upper insulating support, belonging to the technical field of brushless motors. The positioning structure includes: a PCB board and an upper insulating support, and a plurality of positioning platforms are arranged on the upper surface of the upper insulating support, and the top surface of the positioning platform is higher than the top surface of the terminal holder by h; the top surface of each positioning platform is provided with There are guiding and positioning columns matched with the positioning holes and fixing holes matched with the mounting holes. The end of the guiding and positioning columns matched with the positioning holes is a tapered structure, and the side wall of each positioning platform is provided with a wire-passing groove for limiting wires. In the positioning structure of the present invention, during the assembly process of the PCB board and the upper insulating bracket, the guiding positioning column is first matched with the positioning hole, so that the precise positioning between the terminal on the upper insulating bracket and the terminal connection hole on the PCB can be realized, and then It can reduce the number of defective products in automatic production and improve the yield.

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 bracket, a stator core, a lower insulating bracket, and a stator winding. The upper insulating bracket and the lower insulating bracket are r...
