Conductive bracket for motor

Abstract

The invention discloses a conductive bracket for a motor. The comprising a bracket body, wherein the bracket body is provided with three mounting holes, the back side of the bracket body is provided with a positioning insertion groove, each mounting hole is plugged with a conductive connecting rod, the tail end of each conductive connecting rod is bent and inlaid in the positioning insertiongroove, the tail end of each conductive connecting rod is bent and stretches out to the back side from the positioning insertion groove, the front end of each conductive connecting rod stretches out of thecorresponding mounting hole, one end of the bracket body is provided with a harness mounting plate, the harness mounting plate is provided with a harness conductive pin, and the bracket body is provided with a supporting structure for positioning on the back side. The conductive bracket has a reasonable structure, the mounting holes and the positioning insertion groove are formed in the conductivebracket to better mount the conductive connecting rods, the conductive connecting rods and a PCBA board are prevented from being displaced when assembled, the assembly precision is higher, a conductive connecting piece is not needed, the welding operation is reduced, and the conductive efficiency is improved.

Description

Technical field [0001] The invention relates to a conductive support used in a motor. Background technique [0002] The conductive support is a conductive connection part in the motor, and the function of the conductive support is to electrically connect the PCBA board in the motor and the winding of the motor. The conductive support is placed in the heat dissipation cover of the motor, and the PCBA board is set on the conductive support and transfers heat with the heat dissipation cover through thermally conductive glue. The current conductive support main structure includes a conductive connection sheet and a plastic coated outside the conductive connection sheet A bracket member, the conductive connecting piece has a pointed pin bent to the opposite side, the pointed pin is inserted into the connection hole of the PCBA board and then welded and fixed, and the plastic bracket member exposes the conductive connecting piece, and then three metal The rod is welded on the exposed ...

AI Technical Summary

Problems solved by technology

However, this conductive bracket has the following disadvantages: 1. The metal rod is welded to the conductive connecting piece, the connecting piece is welded to the PCBA board, and the other end of the metal rod is welded to the winding. Shaped pins need to be aligned with the tiny connection holes of the PCBA board, which makes assembly difficult

2. The connection between the connecting piece of the current conductive bracket and the metal rod is only fixed by welding, and the length of the metal rod is relatively long. In the actual assembly process, it may be necessary to move it due to the wrong position or deformation of the connecting rod Connecting rod, in this way, it is easy to loosen between the connecting rod and the conductive connecting piece, resulting in poor point contact

3. The positioning support between the current conductive bracket and the PCBA is unreasonable, and the assembly is difficult. At the same time, the PCBA board may be deformed during the long-term use of the motor after assembly.
