Abstract

An electric connector is composed of an insulation body and a plurality of 'omega'-shaped conductivity terminals, wherein the insulation body is provided with a plurality of accesses used to house conductivity terminals. The 'omega'-shaped conductivity terminal comprises an elastic portion taking a shape of a ring and a contacting portion taking a shape of an arch. The arrangement of the ring-shaped elastic portion and the arch-shaped portion prolongs the lengths of the elastic arms of the terminals, thereby largely sharing the orthogonal force which is generated by the elastic opposite housing effect of the terminal and a butt-joint terminal, and effectively reducing the density of the orthogonal force supported by the unit area of terminal, ensuring the elasticity of the terminal, and prolonging the service life of the terminal.

Description
