Low-cost large-current clip terminal for electric connector

Abstract

The invention discloses a low-cost large-current clip terminal for an electric connector. The low-cost large-current clip terminal comprises a terminal body and an elastic clip. The elastic clip comprises a connecting piece and two clamping pieces, wherein the connecting piece has high conductivity and elasticity and is integrally formed, the two clamping pieces are oppositely arranged, and the common end of the two clamping pieces is integrally connected with the connecting piece. The terminal body comprises a conductive plate and two clip opening pieces, wherein the conductive plate has high conductivity and is integrally formed, the two clip opening pieces are oppositely arranged, and one end of one clip opening piece is integrally connected with the conductive plate. The elastic clip is arranged between the two clip opening pieces in a located and sleeved mode. The connecting piece faces the conductive plate and is attached to the clip opening pieces. The two clamping pieces can elastically clamp metal inserts to be connected. According to the low-cost large-current clip terminal, an integrated structure with only one clamping point is replaced by the clip structure with multiple contacts, the connection reliability of the clip terminal can be effectively improved, the size of the elastic contact part of the clip terminal can be decreased, and therefore the consumption of high-conductivity elastic copper materials and the production cost can be lowered.

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.

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
