The coaxial connector is provided with a contact, an internal housing, a shell and an electromagnetic shield plate. The contact has a connecting portion which can connect with a mating side contact, and a crimping portion which crimps the central conductor. The internal housing has a contact receiving chamber opened at a rear end portion, and the connector is retained in the contact receiving chamber. The shell has a shell main body covering an external perimeter of the internal housing, and a cable clamp. The cable clamp fixes an end of the coaxial cable. The shell main body has a lock piece. A pair of slits is provided at both sides of the lock piece. The electromagnetic shield plate is disposed at an upper face of the internal housing, and has one piece which shields a portion of the pair of slits with respect to the internal housing.

A flex flat cable (FFC) is proposed. The FFC comprises a plurality of first signal transmitting lines arranged in parallel with one another. Each of the plurality of first signal transmitting lines comprises a first transmitting conductor configured to transmit a signal, a first insulating layer enclosing the first transmitting conductor, and a second insulating layer, enclosing the first insulating layer. The FFC further includes a first insulating coat enclosing the plurality of first signal transmitting lines, a first ground conductor arranged at one side of the first insulating coat and configured to be grounded, a metallic shielding layer enclosing the first insulating coat and the first ground conductor and a second insulating coat enclosing the metallic shielding layer, and a second insulating coat enclosing the metallic shielding layer.

The first ground conductor contacts the metallic shielding layer.

A receptacle connector is mounted on a board and is to be connected to a plug connector. An insulative housing is to be fitted to a housing of the plug connector. A plurality of electrically conductive contacts is arranged on the housing and connected to terminals (ground terminal and signal terminal) on the board, and are to be connected to electrically conductive contacts of the fitted plug connector. Among the plurality of contacts, at least one of a first contact and a second contact is configured so that the position at which the contact is in contact with a terminal (signal terminal or ground terminal) on the board can be adjusted, the first contact being connected to the signal terminal on the board, and the second contact being connected to the ground terminal on the board.

A cable connector assembly includes: a mating portion; a flat cable electrically connecting with the mating portion, the flat cable having plural wires and an outer boot enclosed the wires, the wires including a first wire and a second wire; an inner mold enclosing a part of the mating portion and a part of the flat cable; and a shielding shell enclosed the inner mold, wherein the first wire is a core wire directly enclosed by the outer boot and the second wire comprises a core wire and an insulative layer enclosing the associated core wire.

A connector is attachable to a front end of a cable in a front-rear direction. The cable comprises coated signal cables and an outer member which protects the signal cables. The connector comprises terminals, a holding member, a shell, an assigned portion and an impedance adjusting portion. The terminals are attached to the signal cables, respectively, under an attached state where the connector is attached to the front end of the cable. The holding member holds the terminals. The shell covers the holding member to have a predetermined surface which intersects with a perpendicular direction perpendicular to the front-rear direction. The assigned portion is located on the outer member of the cable under the attached state. The impedance adjusting portion is located forward of the assigned portion in the front-rear direction and located inward in the perpendicular direction in comparison with both the predetermined surface and the assigned portion.

A cable termination is disclosed that includes a cable with a first and a second insulated conductor positioned in a shield, the cable further including a drain wire. The cable is mounted on a circuit board that includes a first pad and a second pad that are respectively soldered to the first and second conductors. A ground via is positioned in front and between the first and second pads and the drain wire is inserted into and soldered to the ground via.
