RJ45 Connector (also known as connector, English connector), also known as connector and socket in my country, usually refers to an electrical connector, that is, a device that connects two active devices and transmits current or signals.
After the contact between the male terminal and the female terminal of the connector can transmit information or current, it has become an indispensable part of electronic equipment. According to different usage scenarios and different application objects, connectors are also divided into various types. So, what are the common connectors, and what are the specific categories, let's take a look.
In fact, there is no fixed classification of connectors, but in actual use, people usually classify connectors according to their use, shape, structure and performance for better classification and management.
1. Divide according to shape
If divided according to shape, connectors are divided into five types: circular connectors, rectangular connectors, bar connectors, curved connectors and D-type connectors, of which circular connectors and rectangular connectors are the most common!
2. According to the environmental conditions of use
According to the environmental conditions of use, it is mainly divided into sealed connectors, radiation-resistant connectors, high-temperature connectors, low-temperature connectors, automatic detachment and separation electrical connectors, etc.
3. According to electrical requirements
According to its electrical requirements, it can be divided into ordinary connectors, high-power connectors, high-voltage connectors, pulse connectors, low-noise connectors, noise filter connectors, low-frequency connectors, high-frequency connectors, phase modulation connectors and precision connectors. coaxial connectors, etc.
4. According to the structure division
According to different structures, connectors are divided into threaded connectors, straight-in connectors, plug connectors, push-pull connectors and bayonet connectors.
5. According to the termination form of the contact piece
According to the termination form of the contacts, it can be divided into crimp connectors, solder connectors, wrap connectors, surface mount connectors, etc. Note that this classification method applies only to electrical connectors.
6. According to the special structure
According to the special structure, connectors can be divided into meta-plug-force connectors, rubber connectors, rotary connectors, bifurcated connectors and fiber optic connectors
7. Change points according to the level of interconnection
According to the function of internal and external connection of electronic equipment, electrical interconnection can be divided into five levels, namely the internal connection of chip package, the connection between IC package pins and PCB, the connection between printed circuit and wire or printed board, and the bottom plate. Connections to backplanes, device-to-device connections.
8. According to the model of the connector
In the connector industry at home and abroad, there are two ideas for product model naming.
One is to use the letter code and the number to reflect the main structural characteristics of the product in the model name. The advantage of this method is that it is easy to identify, but the arrangement is too long and complicated, which brings a lot of difficulties to printing with the miniaturization of connectors. At present, this method is still popular in China, and it is stipulated in some industry standards and even national standards, such as SJ2298-83 (printed circuit connector), SJ2297-83 (rectangular connector), SJ2459-84 (ribbon cable connection) connector), GB9538-88 (ribbon cable connector), etc.
In foreign countries, the combination of Arabic numerals is preferred. The advantage of this method is simplicity, which is convenient for computer management and logo printing of small products. The major international connector manufacturers are currently using this method.
9. Change points according to the purpose and purpose of use
According to the purpose of use, connectors are divided into mobile phone connectors, power connectors, high-voltage connectors, automotive connectors, aviation connectors, high-speed signal connectors, optical fiber connectors, etc.
The above are the current common types of connectors. In fact, there are many types of connectors, and there is no fixed classification. The above classifications are mainly easy to identify and manage, and there is basically no major difference in function and nature.
