Low cost high current clip terminals for electrical connectors

Abstract

The invention discloses a low-cost, high-current clip terminal for an electrical connector, which includes a terminal body and an elastic clip, and the elastic clip includes an integrally formed connecting piece with high electrical conductivity and elasticity and two opposing clamping pieces , the two clamping pieces are integrally connected to the connecting piece at the same end, the terminal body includes an integrally formed conductive plate with high conductivity and two oppositely disposed jaw pieces, one end of one of the jaw pieces is integrally connected to the conductive plate; The elastic clamping piece is positioned and sleeved between the two clamping pieces, the connecting piece faces the conductive plate and closely contacts the clamping piece, and the two clamping pieces can elastically clamp the metal insert to be connected. The present invention changes the integral structure with only one clamping point, and forms a multi-point contact clip structure, which can effectively improve the connection reliability of the clip terminal, and can reduce the size of the elastic contact part of the clip terminal, thereby reducing the The consumption of highly elastic copper materials saves production costs.

Description

Technical field [0001] The invention relates to a clip terminal for an electrical connector, in particular to a high-current clip terminal for an electrical connector. Background technique [0002] Electrical connectors are an indispensable part of electronic equipment. The application fields are becoming more and more extensive. The form and structure of electrical connectors are ever-changing. With the application object, frequency, power, application environment, etc., there are various types of electrical connections. Device. For pluggable electrical connectors, the easy-to-operate pluggable connection is combined with the firm and universal screw method to connect various parts.

The male connector is inserted into the female connector to be detachably connected through a clamping...

AI Technical Summary

Problems solved by technology

[0004] However, existing clip terminals usually use integral clips or finger-shaped clips, and the integral clip has only one clamping point. For some reasons, the clip terminal may fail or have poor conductive contact, which affects The reliability of the electrical connection of the electrical connector

Moreover, when the integral clip is stamped and manufactured, it is usually impossible to ensure that the two opposite elastic arms of the clip are completely parallel, and sometimes even deviate at a certain angle, resulting in a gap between the metal insert and the clip terminal when the metal insert is inserted into the clip. The contact surface of the contact surface is reduced, resulting in a larger contact resistance and a higher temperature rise of the product, which affects the electrical properties of the electrical connector.

Although the contact stability of the finger-shaped clip has been improved to a certain extent, the thickness of the conductive plate and the clip of the clip terminal is usually thicker, which makes the size of the clip terminal larger, that is, the volume of the product is larger

Since the clip terminals in the prior art are usually made of highly conductive copper (phosphor bronze, beryllium copper) through sheet metal stamping process, it is necessary to consume a large amount of highly conductive copper, However, the price of highly conductive conductive copper is usually more expensive, resulting in the high cost of the entire electrical connector product
