(2) Audio/video connection plug -in

① The two -core and three -core plug socket: It is mainly used for signal transmission between various devices, and the input plug is used as a microphone input signal. The two -core plug socket is mainly used for the connection of a single -channel signal. The three -core plug socket is mainly used for the connection of stereo signals. It is divided into three types: 2.5 mm, 3.5 mm, and 6.5 mm.

② Lotus plug socket: It is mainly used for audio equipment and video equipment, used as the input and output plugs between the two.

③ XLR plug (XLR): It is mainly used for the connection between microphones and amplifiers.

④ Five -core socket (DIN): It is mainly used for the connection between box recording recorders and amplifiers. It can concentrate the stereo input and output signal on a socket.

⑤ RCA plug: RCA plug is mainly used for signal transmission.

(3) Rectangular connector

The rectangular plug socket is made of different numbers of the rectangular plastic case with good insulation performance. The contacts in the plug socket are different, up to dozens of pairs. The arrangement method has two rows, three rows, four rows, etc. Due to the elastic deformation of each contact side, the positive pressure and friction generated by each contact can ensure the good contact of the contact the vice. In order to improve performance, some contact with gold plating or silver -plated layers.

The rectangular plug -in socket can be divided into pins and hyperbolic springs; shells and non -shells; lock -type and non -locking formulas. This connector is often used in low -frequency and low -voltage circuits, high and low -frequency hybrid circuits, and mostly used for radio instruments and instruments. Essence

(4) Round connector

There are two main types of circular connectors: plug -in and snail connection. Insert types are usually used for circuit connections with frequent plugging, less connection points, and a current of less than 1A. Sailing connector is commonly known as aviation plug socket. It has a standard rotating locking mechanism. It is more convenient to connect with a large connection and plug -in force. It is also easy to achieve special requirements such as waterproof sealing and electric field shielding. Large current circuit connection. The number of connections of this type of connection from 2 to nearly 100, the rated current ranges from 1 to hundreds of amps, and the operating voltage is between 300 and 500 volts.

(5) PCB connector

The printed board connector is transitioned from the rectangular connector. It should belong to the category of the rectangular connector, but it is generally listed as a new plug -in. From one to dozens of contact points, it can be used with the bar connector, or it can be used directly with the circuit board. It is widely used in the connection between various boards in the computer host and the motherboard. For reliable connection, the contacts are generally plated to enhance their reliability, commonly known as gold finger.

(6) Other connectors

Other connectors include integrated circuit sockets, power plug sockets, optical fiber connectors, band -shaped cable connectors, etc.
