Abstract

In a multipolar connector plug in which an annular recessed groove is formed in the front face of a square insulating body, and a plurality of contact-receiving holes are formed in the column portion defined inside the annular recessed groove and have female contacts received therein respectively, the front surface of the insulating body is covered with a front shield plate formed of a conductive spring material, and the insulating body is covered with a shield cover so that at least the top rear surfaces and both sides of the insulating body are covered. The front shield plate has a square plate portion having a concentrically made hole equal to or slightly larger than the annular recessed groove, and from the circumferential edge thereof, a plurality of tongue pieces are formed to extend rearward in the annular recessed groove. The front shield cover further includes a contact piece extending rearward from the upper edge of the plate portion along the top surface of the body and a pair of holding pieces extended from the upper and lower edge of the plate portion and bent to the top and bottom surfaces of the body. The contact piece is bent so that at least one of a valley and a crest is formed in the middle portion thereof, and sandwiched by the top plate portion of the shield cover and the top surface of the body to abut the shield cover with a strong elastic force, whereby the front shield plate and the shield cover are electrically connected to each other.
