What is a connector  ?
 
Connector, i.e. connector. Also known as connectors, plugs and sockets in China. Generally refers to electrical connectors. That is, a device connecting two active devices to transmit current or signal.
Connector is a kind of component that our electronic engineers and technicians often contact. Its function is very simple: build a communication bridge between the blocked or isolated circuits in the circuit, so as to make the current flow and realize the predetermined function of the circuit.
Connectors are indispensable components in electronic equipment. If you observe along the current flow path, you will always find one or more connectors. Connector forms and structures are ever-changing. There are various forms of connectors with different application objects, frequencies, power, application environments and so on. For example, the connectors for lighting on the court are very different from those for hard disk drives and rockets.
However, no matter what kind of connector, it is necessary to ensure the smooth, continuous and reliable flow of current. As far as the optical fiber connector is concerned, they are not only used to replace the optical fiber in the optical circuit, but also in the signal transmission system.
What are the classifications of connectors?
Connector, i.e. connector. It is a kind of component that electronic engineers and technicians often contact. Also known as connectors, plugs and sockets in China. Generally refers to electrical connectors. That is, a device connecting two active devices to transmit current or signal. The brands of connectors include canary, Nutrilite, fujinying, Toshiba, MOLEX, etc. Connectors often used in our daily life can be divided into the following categories:


1. Strip / press connector
2. Circular connector
3. Rectangular / heavy duty connector
4. RF coaxial connector
5. PCB / PCB connector
6. Wire to wire connector
7. FFC / FPC / membrane cable connector
8. Flat cable connector
9. Computer equipment connector
10. Video / audio signal connector
11. Mobile phone connector
12. Power connector
13. High voltage connector
14. Vehicle connector
15. Aviation connector
16. High speed signal linker
17. Optical fiber connector
18. Microwave linker
19. Waterproof connector
     At present, the main evaluation standard for the waterproof performance of waterproof connectors is the IP waterproof grade standard. The waterproof performance of the waterproof joint depends mainly on the last two digits XX of ipxx, D and X are from 0 to 6, and the high level of Z is 6; The second number is from 0 to 8, and the high level of Z is 8; Therefore, the Z high waterproof grade of waterproof joint is IP68.
Molded cable accessories are mainly used for straight through waterproof joints of 35kV and above cross-linked cables. It is a joint that is wrapped around the treated cable joint with irradiation crosslinked or chemical crosslinked polyethylene film strip, pressed with the help of a special mold (aluminum mold or heat-resistant tension belt) and heated to form.
In the production process of irradiated cross-linked polyethylene strip, after pre stretching treatment (stretching 30% at 100C, then cooling and coiling), wrapping into joints, heating and retraction, the air gap between the layers of the wrapped strip is compressed, which can improve the air gap discharge voltage. This kind of joint has high partial discharge level and is suitable for making cable joints with high voltage level.
