Electrical connectors are classified in many different ways. According to the frequency classification of high frequency electrical connectors, low frequency electrical connectors; According to the shape classification of circular electrical connector, rectangular electrical connector; Audio equipment electrical connector, power electrical connector, special purpose electrical connector, etc. Electrical connectors come in many categories and are usually classified according to characteristics such as their operating frequency and electrical requirements.
Classification of different operating frequencies of electrical connectors
1. Low-frequency electrical connector: Generally speaking, it refers to the electrical connector whose transmission frequency is less than 100MHz. This type of electrical connector has a large transmission current range, and its structure is mostly multiple wires (hundreds at most).
These include:
Cable electrical connector. This type of electrical connector ends are multi-strand cables, shielded cables, solid wires, etc. Free end electrical connectors and free end with electrical connectors or fixed electrical connectors.
Cabinet electrical connector. It consists of two pairs of fixed electrical connectors. They are respectively mounted on the system frame and unit assembly, connected and separated by the linear reciprocating motion of the unit assembly.
Electrical connector for audio equipment. There are many types of such electrical connectors, such as YS1 circular electrical connectors, concentric electrical connectors, plugs and sockets used in audio equipment.
Electrical connectors for household appliances. This kind of electrical connector is mainly used in black and white TV, color TV and other household appliances, also used in similar structure of equipment.
Electrical connectors for office equipment. This kind of electrical connector is mainly used in copiers, Chinese and English computer printers, microprocessors and other equipment.
2. High frequency electrical connector. Electrical connectors used in circuits with operating frequencies greater than 100MHz. The construction of such electrical connectors shall take into account leakage and reflection of high-frequency electric fields. Because coaxial cables of coaxial structure are commonly used for connection, they are often called coaxial electrical connectors.
3. Hybrid high and low frequency electrical connector. Usually refers to electrical connectors that contain both low and high frequency contact pairs.
Classification by electrical requirements:
Electrical connector according to its electrical requirements can be divided into general electrical connector, high power electrical connector, high piezoelectric connector, pulse electrical connector, low noise electrical connector, anti-interference filter electrical connector, phase modulation electrical connector, precision coaxial electrical connector and so on
Classified by environmental conditions:
Electrical connectors can be divided into sealed electrical connectors, radiation resistant electrical connectors, high temperature electrical connectors, low temperature electrical connectors and so on according to their working environmental conditions.
Classification according to shape structure and installation mode:
Electrical connector according to its appearance and structural characteristics can be divided into circular electrical connector, rectangular electrical connector, linear electrical connector, bending electrical connector, type 1 electrical connector and so on. According to its installation mode, it can be divided into cable electrical connector, panel electrical connector, through-wall electrical connector, etc.
Electrical connectors with special structure according to special requirements:
Special structural electrical connectors include component pluggable electrical connectors, rubber electrical connectors, rotary electrical connectors, split electrical connectors and optical fiber electrical connectors.
