Abstract

The utility model discloses an electrical connector, comprising an insulation body, a contact terminal that is arranged on the insulation body, an elastic terminal and a fixing terminal. Through holes that are used for holding the contact terminal and the elastic terminal are arranged through an upper surface and a lower surface of the insulation body. The contact terminal consists of a main part and an elastic contact arm that bends, inclines and stretches downwards from the upper end of the main part. The elastic contact arm is provided with an inclined guiding face that stretches out of the upper surface of the insulation body. One end of the elastic terminal is pushed against the contact terminal and the other end thereof is pushed against the fixing terminal. Through the design, a docking electrical connection device is guided by a guiding face and is contacted with a contact part of the contact terminal when being inserted along the side direction, which can prevent the contact terminal from being worn.
