What are the categories of electronic connectors?

I. What are the classifications of electronic connectors? Electronic connectors, also often called circuit connectors, electrical connectors, bridge two conductors on a circuit, so that the current or signal can flow from one conductor to the other conductor conductor device. It is widely used in various electrical circuits to connect or disconnect currents or signals. The connection may be temporary and easy to plug and unplug at any time, or it may be a junction between electrical devices or wires. Electronic connector is a device for transmitting electronic signals (analog or digital signals), can provide a separate interface for connecting two sub-electronic systems, is used to complete the electrical connection between the circuit or electronic machine and other components. Such as: power plug / socket, IC foot, telephone line plugs and so on are. Widely used in the electronics industry. Electronic connector is a motor system, which can provide a separable interface to connect the two sub-electronic systems, in short, to complete the electrical connection between the circuit or electronic machine and other components to become a connector that is the bridge between the two. Electronics can be used as inter-circuit, inter-component, inter-system electrical/electronic transmission connection parts, so that the power, signal, current can be stable and reliable flow, but also to facilitate product assembly, maintenance, replacement. 1, according to the soldering method is divided into: DIP type (eg: PCI 120P), SMT type (eg: MINI PCI EXPRESS) 2, according to the appearance of the can be divided into: the external type and internal type (1) External type: I / O: D-subminiature connectors (also known as D-SUB connector), USB, 1394, DDR, VGA, SCSI, etc. CARD: SD, SIM, NEW CARD, etc. JACK: RJ11, RJ45, etc. RF power supply Other: SCSI, DVI, etc. (2) Internal type: board-to-board line-to-board line-to-line flexible circuit board (FPC) ZIFHDD:BOX,PIN-Header&SocketEdge Card:AGP,PCICPC Socket:478,SLOT-1,SLOT-2Memory:DIM,SO-DIM Others:MINI PCI
