Multi-contact high current elastic contact element terminal

Abstract

The invention discloses a multi-contact high current elastic contact element terminal. The contact element terminal comprises an abutting end region (110) and a terminal connecting region (120), wherein the abutting end region (110) comprises a plurality of long contact regions and a plurality of short contact regions, and the contact regions have metal plate stagger structures and form a plurality of front and rear contact zones so as to form multi-contact. The roots of the long contact regions and the roots of the short contact regions are correspondingly distributed on two sides of the abutting end region (110), and the long contact regions are turned to be distributed on the same side as the opposite short contact regions and form contact regions of the same side together with the opposite short contact regions. The abutting end region (110) and the terminal connecting region (120) have mutually reverse folded structures. The contact element terminal has large contact region area and high connecting reliability, effectively reduces the calorific power in the high current transmission process, optimizes a heat dissipation channel, improves the current carrying capability, has small volume, saves the materials, and has low cost.

Description

technical field [0001] The invention relates to an elastic contact terminal applied in an electrical connector, in particular to a large-current elastic contact terminal applied in a power connector installed on a printed board. Background technique [0002] In the interconnection of electronic circuits, power connectors are essential components in the interconnection system of power circuits. Compared with contacts for transmitting signals, high-current contacts used in power connectors need to have elements such as low contact resistance and good heat dissipation conditions to meet the heat reduction and control temperature rise during high-current transmission.
