Different ways of classifying USB connectors. According to frequency, there are high-frequency connectors and low-frequency connectors; according to shape, there are round connectors and rectangular connectors; according to usage, there are PCB connectors, cabinet connectors, acoustic connectors, power connectors, special connectors, etc. The following content is to introduce several ways to classify USB connectors.
USB connectors by frequency classification
USB connectors are classified according to electrical requirements
USB connectors are classified according to environmental conditions.
1. low-frequency connectors: the general connector transmission current is 100MHz or less. This USB connector transmission current range is larger, the structure is more multi-line (up to several hundred lines).
(1) Cable connectors. This type of USB connector consists of a multi-stranded cable or shielded cable and solid wire, free-end connector consists of free-end paired connectors or fixed connectors.
(2) Box connector. It consists of two fixed USB connectors. The two methods are mounted separately on the frame of the system and use the linear reciprocating motion of the unit components to achieve connection and separation.
(3) Spare connectors for mounting audio. There are many USB connectors, such as YS1 ring connectors, coaxial connectors, plugs, audio, etc.
(4) Connectors for household appliances. Such USB connectors are mainly used for home appliances such as black and white TVs, color TVs, and similarly structured home appliances.
(5) Office equipment connectors. This product is mainly used for copiers, Chinese and English computer printers, microprocessors, and other equipment.
(6) Power connectors for electronic and electrical equipment.
2. High-frequency connectors: generally refers to USB connectors used for circuits above 100MHz. The structure of this connector should take into account the leakage and reflection of high-frequency electric fields. Because the coaxial system is usually used to connect, it is also called the coaxial connector.
3. Mixed high and low-frequency connectors: refers to USB connectors that contain both low and high-frequency contact pairs.
They can be divided into general-purpose connectors, high power connectors, high voltage connectors, pulse connectors, low noise connectors, anti-interference filter connectors, phase modulation connectors, coaxial connectors, etc.
USB connectors can be divided into sealed connectors, anti-radiation connectors, high-temperature connectors, low-temperature connectors, etc. According to the working environment conditions.
After understanding the classification of the above several USB connectors, it is beneficial for us to correctly identify the different types of USB connectors, so that we can judge their application areas and use.
