Electric connector having cover case

Claim 1

An electric connector comprising: a nonconductive connector body having: contacts arranged therein; a coupling portion adapted to be coupled to a mating conductive connector shell; and, a rear end portion accommodating the wire connecting parts of said contacts; a pair of cover case halves forming a nonconductive cover case when coupled to each other; a pair of shielding case halves forming a conductive shielding case when coupled to each other and when coupled to a shield cable clamp member; said coupling portion of said nonconductive connector body being provided in at least one side wall of the coupling portion with a shield contact tongue hole through the side wall; each of said cover case halves having a gripping piece at the front end thereof, said gripping pieces of said cover case halves being adapted to grip both sides of said nonconductive connector body to hold said nonconductive connector in place in such a manner that at least said shield contact tongue hole can be covered by the gripping pieces when said cover case halves are coupled to each other; each of said cover case halves having a first recess and a second recess, said first recess having an open end adjacent to said gripping piece, said open ends of said first recesses being adapted to form an opening for receiving a rear end portion of said nonconductive connector body when said cover case halves are coupled to each other, said second recess being adapted to form a clamp member receiving cavity for accommodating said sheilded cable clamp member when said cover case halves are coupled to each other, the rear end of said first recess communicating with the front end of said second recess through a passage adapted to receive said shielded cable, the rear end wall of said second recess having a notch formed therein, the notches of said cover case halves being adapted to form an opening for receiving said shielded cable when said cover case halves are coupled to each other; each of said shielding case halves being adapted to be disposed within said first recess of said corresponding cover case halves so as to extend over substantially all of the inner wall surfaces of said first recess except said open end and said passage; at least one of said shielding case halves being provided at the front end thereof with a resilient shield contact tongue, said shield contact tongue to extend along and between said gripping piece of said corresponding cover case half and said side wall of said coupling portion of said nonconductive connector body held therein, said shield contact tongue having an inwardly convexed contact point to enter into said shield contact tongue hole and protrude slightly and inwardly beyond the inner surface of said side wall of said coupling portion so as to make contact with said mating conductive connector shell when coupled to said coupling portion of said nonconductive connector body, the front end of said shield contact tongue being adapted to be covered by the front inner wall of said shield contact tongue hole in the coupling direction of said mating conductive connector shell; said shielded cable clamp member being adapted to make electrical contact with the shielding wire of said shielded cable and then be placed in said clamp member receiving cavity; said shield case halves being provided at the rear end thereof with at least one clamp member contact lug which can be located along the front inner wall of said second recess, the front end face of said clamp member adapted to be brought into pressed contact with said clamp member contact lug located along the front inner wall of said clamp member receiving cavity when said clamp member is pressed into said clamp member receiving cavity.
