A cable connector includes a number of cables and an electrical connector. Each cable includes a core wire, an insulating layer wrapped on the core wire and a shielding layer wrapped on the insulating layer. The electrical connector includes an insulating body, a number of conductive terminals and a shielding shell. Each conductive terminal includes a contact portion for mating with a mating connector and a tail portion connected with the core wire. The cable connector further includes a ground shield mounted to the cables. The ground shield is connected with the shielding layers of the cables, and the ground shield is connected with the shielding shell. Compared with the prior art, the present disclosure improves the shielding performance of the cable connector by providing connecting the ground shield, the shielding layers and the shielding shell together.

A connector is provided with three or more terminals to be respectively connected to wires, and a housing for holding the three or more terminals. The three or more terminals are arranged along a first direction. Each of the terminals includes a wire connecting portion to be connected to the wire, a terminal connecting portion to be connected to a mating terminal and an intermediate portion provided between the wire connecting portion and the terminal connecting portion. Three or more of the terminal connecting portions are arranged at intervals along the first direction. Three or more of the wire connecting portions are arranged at intervals along the first direction. The intervals and the intervals are different from each other. Three or more of the intermediate portions are formed to have mutually different shapes according to differences between the intervals and the intervals.

A protection end cover for a sealing ring includes a body having a first end insertable into an insertion hole of a housing of a connector and a second end positioned outside the housing, a first flange on a first outer peripheral surface of the first end of the body, and a second flange on a second outer peripheral surface of the second end of the body. The first flange engages with a blocking part of the housing to prevent the protection end cover from being pulled out of the insertion hole. The second flange abuts against an outer end surface of the housing to limit the protection end cover at a predetermined insertion position.

A connector housing assembly includes an inner housing, a cable seal and a housing seal. The inner housing defines a plurality of terminal mounting holes for fixedly mounting a plurality of terminals. The cable seal is installed in the inner housing and is adapted to form a seal between the inner housing and a cable extending into the inner housing. The housing seal is sleeved on an outer side of the inner housing and is adapted to form a seal between the inner housing and a mating housing of a mating connector.

A network communication device includes communication circuitry configured to communicate signals over a network cable, and a connector configured to connect to the network cable. The connector includes one or more signal terminals, an inner shield connection and an outer shield connection. The one or more signal terminals are configured to connect to one or more signal conductors of the network cable for communicating the signals. The inner shield connection surrounds the one or more signal terminals and is connected to a circuit ground of the communication circuitry. The outer shield connection surrounds the inner shield connection and is connected to an additional ground of the network communication device, the additional ground being different from the circuit ground.
