1.Multi conductor cable connector,including DB connector and DIX connector and DIN connectors, and so on.

(1) DB connectors include DB-9, DB-15, DB-25. Connector is used to connect serial devices and parallel cable, divided into positive end and negative end, DB25 representatives of DB is in d-type connector, figures represent the number of connector pins. DB25 connectors in the positive end and negative end number 25 on behalf of number of connector pins. Commonly used connector is the current computer and line interface device.

(2) DIX connector, it looks like a connector. While it is connected is implemented with sliding buckle connectors, fixed by screws, often used to connect to a thick Ethernet network.

(3) DIN connectors DIN connector has a different arrangement of pins and needles, which is generally in Macintosh connector: different pin in the connector and pin arrangement, which is generally used in the connections in the network and AppleTalk networks.

2. UTP connector

Twisted pair connector includes two types of connectors: RJ45 and RJ11, is to describe the interfaces of the public telecommunications network.

(1) RJ11 connector is a telephone cable connectors, support and cables, are generally used for user's telephone line access. Connector: class is a phone line connectors supporting 2-wire and 4-wire is typically used for user's telephone line access. RJ11 connector is a telephone cable connectors.

(2) RJ45 connectors of the same type connectors, jacks, larger than RJ11 connector, is the same type of connector, large connector and supports 8 wire modular interface commonly known as standard 8-bit are used for network connections in twisted-pair cable. Standard modular interface commonly known as are used for network connections in twisted-pair cable. Circuits are used because it is the balance type of transmitter modules interface commonly known and accepted, so it has high common-mode rejection ability. And receivers, so it has high common-mode rejection ability.
