By the way, the inventor of this invention is developing the electrical connector type in which the plug connector of the cable side encloses the receptacle connector of the board | substrate side from the left and right. In this electrical connector, an arm having a claw formed at the tip is attached to the plug connector. When fitting the plug connector to the receptacle connector, the arm bends as the claw contacts the left and right sides of the receptacle connector, and the claw slides on the left and right sides of the receptacle connector.
