Classification method of electrical connectors

There are many different classifications of electrical connectors. According to the frequency classification, there are high-frequency electrical connectors and low-frequency electrical connectors. According to the shape classification, there are circular electrical connectors and rectangular electrical connectors. Classified according to use, including printed board electrical connectors, cabinet electrical connectors, audio equipment electrical connectors, power electrical connectors, special purpose electrical connectors, etc. There are many types of electrical connectors, usually classified according to their operating frequency and electrical requirements.

Electrical connectors are classified according to different operating frequencies.

Low-frequency electrical connector: usually refers to the transmission signal frequency of less than 100mHz electrical connector. This type of electrical connector has a large transmission current range, and its structure is mainly multi-wire (up to hundreds of lines), including:

A. Cable connectors. The terminal of the electrical connector is composed of various cables, shielded cables and solid cables. Free end electrical connector and free end insert electrical connector or fixed electrical connector.

B. Cabinet type electrical connector. It consists of two pairs of fixed electrical connectors. They are mounted on the system frame and unit parts respectively and are connected and separated by the linear motion of the unit parts.

C. Electrical connectors for audio equipment. YS1 round electrical connectors, concentric electrical connectors, plug sockets and other electrical connectors wide variety.

D. Electrical connectors for household appliances. The electrical connector is mainly used for black and white TV, color TV and other household appliances, and can also be used for equipment with similar structure.

E. Use electrical connectors for office equipment. Electrical connectors are mainly used in copiers, Chinese and English computer printers, microprocessors and other equipment.

F. Use power connectors for electronic devices.

G. Environment-resistant electrical connector.

H. Special electrical connectors.

High frequency electrical connector. Usually refers to the electrical connector used in the circuit, the operating frequency is greater than 100mHz. Leakage and reflection of high-frequency electric fields should consider the structure of the electrical connector. They are often referred to as coaxial electrical connectors because they are usually connected to a coaxial structure via a coaxial cable.

Hybrid high and low frequency electrical connector. It usually refers to an electrical connector that contains both low frequency and high frequency contacts.

Classification according to electrical requirements:

According to its electrical requirements, electrical connectors can be divided into general electrical connectors, high-power electrical connectors, high-voltage electrical connectors, pulse electrical connectors, low-noise electrical connectors, anti-interference filter electrical connectors and phase modulation electrical connectors. Equipment, precision coaxial electrical connectors, etc.

Classification according to environmental conditions:

Electrical connectors can be divided into sealed electrical connectors, radiation resistant electrical connectors, high temperature electrical connectors, low temperature electrical connectors, etc. It depends on the environment in which it works.

Classified according to appearance structure and installation method:

Electrical connectors can be divided into circular electrical connectors, rectangular electrical connectors, direct electrical connectors, curved electrical connectors, type 1 electrical connectors, etc. According to its shape and structural characteristics, it can be divided into cable electrical connectors, panel electrical connectors, through-wall electrical connectors, etc.

According to special requirements, electrical connectors of special structure:

Special structural electrical connectors include component plug-in electrical connectors, rubber electrical connectors, rotary electrical connectors, isolation electrical connectors and optical fiber electrical connectors.
