Abstract
Abstract An electric circuit board unit includes an electric circuit board, electroconductive plates disposed at both sides of the electric circuit board, and an electric connector for making a connection between the circuit board and a cable connector. The electric connector comprises an insulator (15), a plurality of contacts mounted on the insulator, an electroconductive shell (17) attached to the insulator, and connecting means attached to the shell. The connecting means provides for connecting the electroconductive plates (3) and the shell (17) when the insulator is assembled in the unit. A coupling portion of the insulator has a plate portion (71), portions (21) of the contacts (16) being arranged on and along one surface thereof, and projecting portions being formed at both sides of the plate portion. The projecting portions (73) project toward one surface of the shell facing the contact portions. A coupling portion of the cable connector has a receiving hole (95) and receiving grooves (96) for receiving the coupling portion and the projecting portions of the electric connector, respectively, to prevent an incorrect connection between the electric connector and the cable connector.
