AI Technical Summary

Technical Problem

In existing coil frames, the distance between the starting and ending points of the winding is too close, which can easily lead to short circuit risks. In addition, there are problems such as scratches on the enameled wire and wire misalignment during the winding process.

Method used

A guide block extending to the vicinity of the magnetic post is set on the side of the wire groove facing the central magnetic post to guide the starting point of the winding to a position close to the magnetic post. The guide block and the inclined surface on the baffle form a directional wire outlet, increasing the distance between the starting point and the ending point. At the same time, a retaining wall and a limiting protrusion are set to prevent the wire from collapsing and to fix the magnetic core.

Benefits of technology

It effectively avoids short-circuit risks, ensures winding stability and neatness, improves insulation reliability and vibration resistance, and is suitable for complex electromagnetic designs and multi-layer winding.
