Description

Internet cable plug

technical field

The utility model relates to a cable connection structure, in particular to a network cable plug.

Background technique

The rapid development of communication network makes it necessary for each computer to be connected to a network line to achieve data transmission. In a general design, a plug is installed at the end of the network cable to be inserted into the network cable socket of the computer to complete the network connection.

The network cable has a cylindrical insulating jacket, in which four pairs of twisted and extended cores are arranged to maintain the characteristics of the network cable and achieve the speed of data transmission. The traditional network cable plug has a sheath that fixes the end of the network cable, so that the end of the network cable extends into the sheath body, and then uses a positioning seat in front of the body to twist and arrange eight wire cores in parallel; the wire cores pass through A bracket is extended into the slot of the plug body, and the wire core is pierced by a piercing metal conductive sheet to complete the conductive connection. When the plug is inserted into the network socket of the computer, the metal conductive sheet will be connected with the gold pin in the socket to transmit data.

Due to the design of the positioning seat in front of the sheath body in the known network cable plug structure, the cable cores of the network cable are twisted and arranged in parallel, which will reduce the characteristics and affect the speed and quality of data transmission, which needs to be improved.

In addition, some network cables have a grounding wire, and a metal shell will be installed outside the network cable plug to achieve the shielding effect. Most of these metal shells are all-inclusive designs that completely cover the main body of the plug. Sometimes, it will cause interference in signal transmission. In particular, when this known all-encompassing metal shell is connected to the ground wire of the network line, the external tail end is used as a tail button to process and clamp the ground wire, which will cost more man-hours, or the metal shell and the ground wire will be connected to each other. The connection is only connected by a single joint at the tail, which causes the instability of the contact and needs to be improved.
