Abstract: A shielded electric connector comprises contact pins each of which includes a contact portion on one end thereof for coming into contact with a mating contact piece, and a joint portion on the other end thereof for connecting an electric wire to be connected, an insulating housing in which the contact pins are disposed and held, a shield hood member which includes a front envelope that encloses the contact pins disposed and held in the insulating housing and a rear envelope that is formed so as to be continuous to and unitary with the front envelope, the hood member having open on only one side and formed with an electric wire lead-out portion, a shield lid member adapted to be coupled to the shield hood member in a manner to close the opening of the shield hood member, and a shield connection part adapted to be connected to a shield layer of the electric wires. A method of connecting electric wires to such shielded electric connector is also disclosed.

Abstract: A coupling engagement mechanism for an electric connector comprises engagement fixtures and an insulating housing element which includes engagement fixture receiving portions for accommodating the engagement fixtures. Each of the engagement fixtures is unitarily formed of a springy metal plate. An engagement portion which engages an abutting portion of a mating connector is formed at one end of a body of each engagement fixture. A manipulation portion is formed at the other end of the body. Elastic pieces whose upper ends are continuous to the body and which extend downwards are formed on both right and left sides of the body. Each of the elastic pieces is formed with, at least, a first coming-off-preventive bend and a second coming-off-preventive bend at a predetermined interval in a direction of the extension. Each engagement fixture receiving portion of the insulating housing element is formed with a first protuberance and a second protuberance at an interval in the extending direction.

Abstract: A locking mechanism for connectors comprises a locking member having an engaging portion, a pressing portion and a fulcrum between the engaging portion and the pressing portion. The fulcrum of the locking member has a bent portion mounted around a fulcrum projection formed on a connector cover. The connector cover is formed with a wall extending inside of the projection. The pressing portion is formed with an elastic tongue piece for displacing outwardly the pressing portion and inwardly the engaging portion about the projection with the free end of the tongue piece in contact with the wall when the fulcrum is mounted on the projection, whereby the engaging portion is externally swung open about the projection when the pressing portion is pressed inwardly against the displacing force of the tongue piece. The pressing portion is formed with a stopper for stopping the pressing portion from further inwardly moving by making contact with the extension of the wall.

Abstract: A locking device for locking the coupling of a connector plug with a connector receptacle comprises a metal engaging piece provided at one of the connector plug and receptacle and a resin engaging portion provided at the other to be engaged by the metal engaging piece. A metal piece is mounted on the engaging part of the resin engaging portion.

Abstract: A cord clamping mechanism comprises a cord clamp and a clamp mounting base for mounting the cord clamp. The cord clamp has a ring-shaped portion for passing a cord to be clamped, and a pair of legs extending from both ends of the ring-shaped portion for clamping the cord passed through the ring-shaped portion when the legs are closed. The legs are formed with openings for passing a clamping screw for closing the clamp and mounting fixedly on the base. The base is formed with a threaded opening for receiving the screw. The cord clamping mechanism further comprises a guiding projection to be inserted into the opening at a position near the ring-shaped portion between the screw and the ring-shaped portion when the clamp is mounted on the base.

Abstract: A lock pin for mounting a board-mount type connector on a board is formed of an elastic material and comprises an upper lateral arm, a pair of spaced long central legs respectively extending downwardly from the center of the upper lateral arm and a pair of spaced short outside legs respectively extending downwardly from the upper lateral arm along the outsides of the central legs. The central legs are adapted to be inserted into a lock pin mounting opening formed at one member of the connector from the upper surface side of the one member to project from the lower surface side of the one member over a considerable length and be inserted into a lock pin inserting opening of the board. The central legs are respectively formed at the lower ends thereof with side projections to be engaged with the periphery of the lock pin inserting opening.

Abstract: In a connector in which a plug connector is held in a cover, locking members are mounted on the cover, and when the plug connector is engaged with a receptacle connector the locking members automatically engage locking pieces of the receptacle connector to lock the connectors in an engaged state, the plug connector is entirely housed in the cover for release levers of the locking members used for unlocking. The locking pieces of the receptacle connector are formed integrally with the body of the connector and each is fitted into a square reinforcing frame formed integrally with the flange of a metallic shell of the receptacle connector, by which the locking pieces are mechanically reinforced.
