AI Technical Summary

Technical Problem

When winding, it is necessary to ensure that each turn fits tightly to avoid gaps between coils. The speed of the winding machine changes suddenly when it starts and stops, causing instantaneous fluctuations in the tension of the enameled wire. This causes the first layer of winding to spring back or shift, resulting in local loosening, affecting the winding effect of the coil, increasing the risk of short circuit in the common mode inductor, and affecting the safety of use.

Method used

The system employs a structure including a limiting installation frame, a position fixing clamp, a limiting installation cylinder, a limiting structure, a coil tensioning plate, a limiting compression wedge, and a position adjustment screw. The coil tensioning plate tightens the initial coil, reducing the gap between the outer coil and the initial coil and ensuring tight winding. The insertion of the limiting installation frame and the positioning mounting seat provides stable support, and the anti-slip rubber sheet compensates for gaps, simplifying the installation and disassembly process.

Benefits of technology

Ensuring tight coil winding reduces the risk of coil displacement, decreases the possibility of common-mode inductor short circuits, improves safety, and simplifies the installation and removal process of common-mode inductors, saving time.
