AI Technical Summary

Technical Problem

Existing inductors are prone to relative displacement between the coil and the magnetic core under vibration, external impact, or thermal stress, which leads to fluctuations in magnetic circuit coupling efficiency and poses a safety hazard.

Method used

By setting springs and abutments in the mounting holes at both ends of the magnetic core, a multi-point support structure is formed in conjunction with the coil and the magnetic core. The buffering effect of the springs is used to suppress the radial displacement and axial movement of the coil, and the end blocks limit the movement to ensure the stability of the coil and the magnetic core.

Benefits of technology

This improves the stability of the coil on the magnetic core, reduces the risk of displacement caused by vibration and external impact, ensures stable magnetic circuit coupling efficiency, and enhances safety and practicality.
