Conext industry knowledge

Connector, CONNECTOR. Domestically referred to as connectors, plugs and sockets. A connector is generally referred to as an electrical connector. That is, a device that connects two active devices to transmit current or signals.

Electronic connectors are generally classified into I/O (Input / Output) and Interconnection. I/O classes are used to connect computer systems to peripheral devices. Such as mouse, monitor, keyboard, lister plotter and network. The signal transmission between the systems is used. Related products include D-SUB, USB, _IEEE1394, etc. Interconnection is applied in the main system and peripheral devices, and is connected to the electrical signal between the electronic zero load and each system module. The related products have integrated circuits. Sockets (ZIF series) and board edge connectors (SLOT, DDR, PCI, etc.), other categories of connectors are as follows:

According to the PCB bonding type:

DIP (through-hole adhesion): Its product requires the positive position of the terminal pin (True position).

SMT (Surface Adhesion): Its product requires the position of the terminal pin (True position) and the coplanity of the terminal.

According to the use of industry points:

PC PC connector: such as ZIF 478, DDR184, BATTERY, PCI, AGP, I/O

Communication connector: M/J RJ11, M/J RJ45 , SIMM CARD

Industrial Control Connectors: COMPACT PCI

Aviation connector

Medical connector
