(1) Wiring Terminal
Terminals are mainly produced to facilitate the connection of wires. In reality, a terminal block is a piece of metal wrapped in insulating plastic. Both ends of the sheet metal have holes for inserting wires. There are screws for tightening or loosening. Sometimes two wires need to be connected, sometimes they need to be disconnected. At this point, it can be connected with terminals, and can be disconnected at any time without soldering or entanglement, which is convenient and fast. There are many types of terminals, commonly used are plug-in terminals, PCB-type terminals, terminal blocks, screw-type terminals, grid-type terminals and so on.
Terminal features: various pin spacing, flexible wiring, suitable for high-density wiring requirements; the maximum current of the terminal is up to 520 A; suitable for SMT production process; Accessories to expand functionality.
(2)Audio/Video Connector
① Two-pin, three-pin plug and socket: mainly used for signal transmission between various devices, and the input plug is used as the microphone input signal. The two-pin plug and socket are mainly used for the connection of mono signals, and the three-pin plug and socket are mainly used for the connection of stereo signals. According to its diameter, it is divided into three types: 2.5 mm, 3.5 mm, and 6.5 mm.
②Lotus plug socket: mainly used for audio equipment and video equipment, as the input and output plug of the line between the two.
③ XLR plug (XLR): mainly used for the connection of microphone and power amplifier.
④ 5-pin socket (DIN): mainly used for the connection between the cassette recorder and the power amplifier. It can combine stereo input and output signals on one socket.
⑤RCA plug: RCA plugs are mainly used for signal transmission.
(3) Rectangular Connector
Rectangular plugs and sockets are made of different numbers of contact pairs in a rectangular plastic housing with good insulating properties. The number of contact pairs in the plug and socket varies, up to dozens of pairs. Arrangement, there are two rows, three rows, four rows and so on. Due to the elastic deformation of each contact pair, the generated positive pressure and friction can ensure good contact of the contact pair. To improve performance, some contact pairs are plated with gold or silver.
Rectangular plug and socket can be divided into pin type and hyperbolic spring type; with shell and without shell; there are locking and non-locking types, this connector is often used in low-frequency low-voltage circuits, high-low frequency hybrid circuits, and mostly used in radio instruments .
(4) Circular Connectors
There are two main types of circular connectors: plug-in and screw-on. The plug-in type is usually used for circuit connections with frequent plugging and unplugging, few connection points, and current less than 1A. Screw connectors are commonly known as aviation plugs and sockets. It has a standard rotary locking mechanism, which is more convenient for connection in the case of multiple contacts and large plug-in force, and has excellent anti-vibration performance; at the same time, it is also easy to achieve special requirements such as waterproof sealing and electric field shielding, which is suitable for applications that do not require frequent plugging and unplugging. High current circuit connections. This type of connection has anywhere from 2 to nearly 100 contacts, current ratings from 1 to hundreds of amps, and operating voltages between 300 and 500 volts.
(5) PCB Connector
Printed board connectors are transitioned from rectangular connectors and should belong to the category of rectangular connectors, but are generally listed separately as new connectors. The contact points vary from one to dozens, and can be used with strip connectors or directly with circuit boards, which are widely used in the connection of various boards and motherboards in computer mainframes. For reliable connection, the contacts are generally gold-plated to enhance their reliability, commonly known as gold fingers.
(6) Other Connectors
Other connectors include integrated circuit sockets, power plug sockets, fiber optic connectors, ribbon cable connectors, etc.
