AI Technical Summary

Technical Problem

Due to the limitation of material performance, the conductive terminals in the IEC female plug of the existing HI-FI audio equipment have low conductivity and high resistivity, which limits the full performance of sound quality. The soft metal conductive terminals are prone to deformation, affecting product quality and service life.

Method used

The structure of the base having a stepped hole and a lateral hole is adopted. Combined with the wiring part, a plurality of contact sheets and an elastic conductive ring in the conductive terminal, the circumferential and axial limits of the conductive terminal are realized through the coordination of the stepped hole and the lateral hole, and the deformation of the contact sheet is limited by the elastic conductive ring.

Benefits of technology

Effectively fix the conductive terminals, maintain their structural stability, simplify the mold structure, reduce production costs, extend service life, and ensure the stability of electrical energy transmission.

Abstract

The utility model provides a sound equipment IEC female plug comprising a pedestal which is provided with a through stepped hole and a lateral hole communicated with the stepped hole; the conductive terminal is arranged on the base in a removable manner and comprises a wiring part, and a wire locking hole is formed in the side wall of the conductive terminal and is matched with the stepped hole so as to form circumferential limiting on the wiring part; the plurality of contact pieces are integrally formed and connected with the wiring part, the plurality of contact pieces are annularly enclosed along the circumferential direction of the wiring part to form a plugging hole, and an elastic gap is formed between every two adjacent contact pieces; the elastic conducting ring sleeves the outer sides of the plurality of contact pieces; and the locking piece can penetrate through the lateral hole to be matched with the wire locking hole, and forms axial limiting for the wiring part and detachable connection between the conductive terminal and the base. According to the invention, the structure stability of the conductive terminal is maintained, and good contact between the conductive terminal and the terminal in the plug is also facilitated.
