Abstract
The utility model discloses an electric connector and terminals thereof. The terminals are used for being coordinated with a lifting cover. Each of the terminals is provided with a fixing arm, an elastic arm and a transition part which is used for connecting the fixing arm and the elastic arm. The transition part extends to form a welding part. The welding part extends to form a supporting and holding arm. The elastic arm is positioned between the fixing arm and the supporting and holding arm. The elastic arm is longer than the supporting and holding arm. The cam of the lifting cover is accommodated between the elastic arm and the supporting and holding arm. Because the cam is accommodated in the position which is relatively rear to the elastic arm and the supporting and holding arm is relatively short, the lifting cover is subjected to a relatively large clamping force from the elastic arm and the supporting and holding arm when the lifting cover is closed so that the lifting cover is not easy to be opened arbitrarily by an external force.
