According to different usage scenarios and application objects, connectors are also divided into various styles and types. What are the common types of connectors? What are the specific classifications? In fact, there is no fixed classification for connectors, but they are usually classified according to their usage, shape, structure and performance! If classified by purpose, connectors are divided into mobile phone connectors, power connectors, high-voltage connectors, automotive connectors, aerospace connectors, high-speed signal connectors, optical fiber connectors, etc. If classified by shape, connectors are divided into four types: circular connectors, rectangular connectors, bar connectors and D-type connectors, among which circular connectors and rectangular connectors are the most common! According to structure, connectors are divided into threaded connectors, straight-in connectors, pin connectors, push-pull connectors and bayonet connectors. There are many types of connectors, with no fixed classification. The above are the common classifications of connector types. Of course, there are definitely more than these types. As for other connectors that can be divided into different types according to installation methods and special performance, we will not list them one by one here!
