The crystal plug is an important interface device in network connection. It is a plastic connector that can be inserted in a fixed direction and automatically prevents it from falling off. It is used for network communication. It is named "crystal plug" because of its crystal-like appearance. It is mainly used to connect network card ports, hubs, switches, telephones, etc. RJ-11 and RJ-45 are commonly used, and RJ-45 for computer networks is a common name for the standard 8-bit modular interface. In the past four categories, five categories, super five categories, including the newly introduced six categories of wiring, the RJ type interface is used.

The crystal head mainly has the following types: (1) RJ-45 crystal head: the two ends of each twisted pair are connected to the network card and the hub (or switch) by installing RJ-45 connectors. The RJ-45 plug is a plastic connector that can only be inserted in a fixed direction and automatically prevents it from falling off. This RJ-45 plug must be installed at both ends of the twisted pair so that it can be plugged into a network card (NIC), hub (Hub) or On the RJ-45 interface of the switch (Switch), carry out network communication. (2) RJ11 crystal head: The RJ11 interface is very similar to the RJ45 interface, but there are only 4 pins (the RJ45 has 8 pins). In computer systems, RJ11 is mainly used to connect modem modems. In daily applications, RJ-11 is commonly used in telephone lines.
