An electric connector module to electrically connect a camera module with a circuit board comprises an insulator with a pedestal and four side walls, a storage position composed of the pedestal and four side walls, a popularity of signal terminal in the insulator and a shell on the insulator. Wherein, the shell is composed of four independent side plates. Four grooves are arranged on the side plate. An elastic arm is formed by bending one end with the center of the groove. The shell with four plates can better control production process and the elastic arm facilitates the camera module plug and push-out operation.
