AI Technical Summary

Technical Problem

Traditional inductor connection terminals are prone to loosening due to external pulling or displacement, affecting connection stability.

Method used

The structure includes a terminal body, a rubber sleeve, a mounting plate, a flexible threaded plate, a limiting strip, and a locking nut. The rubber sleeve and the terminal body have a gradually expanding and contracting structure, and the locking nut squeezes the flexible threaded plate to provide additional fixing points and increase friction to ensure connection stability.

Benefits of technology

It effectively prevents the connection terminals from becoming loose, enhances the stability of the inductor pin connection, reduces the impact of external forces, prevents pin wear, and ensures the long-term stability of the connection.

Abstract

This utility model relates to the field of inductor wiring technology, and in particular to an anti-loosening structure for inductor connection terminals. It includes a terminal body, a rubber sleeve, a mounting plate, an elastic threaded plate, a limiting strip, and a locking nut. The rubber sleeve is disposed on the periphery of the terminal body, located at the front end of the terminal body. The mounting plate is fixedly connected to the front end of the rubber sleeve. Multiple sets of elastic threaded plates are fixedly installed on the front end of the mounting plate. The limiting strip is fixedly installed at the front end of the elastic threaded plates. The locking nut is threadedly connected to the periphery of the multiple sets of elastic threaded plates, located between the mounting plate and the limiting strip. This utility model, by rotating the locking nut around the multiple sets of elastic threaded plates, can compress the elastic threaded plates, causing them to deform towards the axis of the rubber sleeve. This clamps and fixes the periphery of the lead wire inserted into the body, providing an additional fixing point, reducing the impact of external forces on the inductor lead connection, and ensuring connection stability.
