A wire loosening and wire winding integrated crossover structure for a magnetic resistance type revolution speed sensor coil skeleton

Abstract

The invention belongs to the technical field of sensors and in particular provides a wire loosening and wire winding integrated crossover structure for a magnetic resistance type revolution speed sensor coil skeleton. The structure comprises a coil skeleton; one side surface of the coil skeleton is a wire outgoing end surface; a plurality of distributing poles are fixed vertically on one side of the wire outgoing end surface; the wire outgoing end surface is provided with a plurality of through holes and each through hole is located in a trajectory of a varnished wire connected between the corresponding distributing pole and the coil skeleton; the connecting lines between the through holes and the centers of the distributing poles are parallel. With the distributing poles and the through holes, each output varnished wire has a certain loosening allowance; a wire breakage rate is greatly reduced and the production quality is high; an automatic coil winding machine can be used for distributing and winding, so that automation and integration are achieved and production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an integrated loosening and winding crossover structure of a magnetoresistive speed sensor coil frame. Background technique [0002] The existing magnetoresistive speed sensor on the motor and its installation structure include the sensor body, output wire, coil frame and enameled wire winding. The multiple output wires wound from the coil frame are manually divided and pulled to the welding port for welding. , and a slack allowance must be left to prevent shrinkage and breakage after welding, gluing or weather; among them, enameled wires are often very thin, even reaching 0.09mm. At present, machines or humans are used to move horizontally through a comb-shaped tool, so that each output wire is pre-tightened and stretched for a certain length to achieve the purpose of loosening the margin; however, the enameled wire is often easily broken, and the wire breakage rate ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defect that the enameled wire is easily broken when there is a loose margin of the enameled wire wound out in the prior art, the wire breakage rate is extremely high, and the production quality is poor. The output enameled wire has a certain slack margin, and at the same time, it can greatly reduce the wire breakage rate, and the production quality is high; the automatic winding machine can be used to cooperate with the sub-wire winding to realize automatic integration, and the reluctance speed with high production efficiency Loosening and winding integrated wire crossing structure of the sensor coil skeleton
