Abstract
The utility model provides an electric connector and a terminal thereof. The electric connector can connect a chip module with a plurality of insertion pins to a circuit board at the outer part. The terminal of the electric connector comprises a base part fixedly arranged at an insulating insertion hole of the electric connector, a welding part extending downwards from the base part, and an elastic arm bending and extending upwards from the base part. The elastic arm extends to one horizontal side of the base part in a bending manner, a first elastic arm extending towards one side of the elastic arm is arranged on the base part, the elastic arm is provided with a second elastic arm, and the first elastic arm and the second elastic arm present a splayed shape. When the insertion pin is matched with the terminal of the electric connector, the elastic arm and the second elastic arm are spread out, so as to lead to mild lateral deviating deformation of the insertion pin; through proper size setting of the elastic arm and the second elastic arm, the lateral non-deviating deformation of the insertion pin can even be realized.
