A connector is an electromechanical component used to connect two or more circuits, cables, or components, enabling the transmission and exchange of current and signals, as well as providing a secure mechanical connection. It acts as the “interface master” in electronic devices, allowing different components to “join hands and cooperate” smoothly.
Connectors operate through the interlocking of plugs and sockets. The pins of the plug precisely align with the sockets of the socket. When they are tightly connected, the metal contacts conduct electricity, forming a path for current or signal transmission. Meanwhile, the housing, locking mechanisms, and other structures of the connector ensure a stable connection and prevent loosening that could affect transmission.
The primary function of connectors is to facilitate the assembly, maintenance, and upgrade of equipment. In the production of electronic products, using connectors allows for the rapid assembly of different functional modules, improving production efficiency. When equipment malfunctions, it is easy to disassemble for inspection and replacement of components. With technological advancements, it is also simple to replace them with more advanced components. Additionally, connectors optimize circuit layouts, making the internal structure of electronic devices more compact and rational.
Connectors come in a wide variety of types. By shape, they include circular connectors, rectangular connectors, etc. By application, they include power connectors, signal connectors, etc. The Type-C connector commonly found on mobile phones is a compact rectangular connector that integrates charging and data transmission functions. In contrast, circular connectors used in aerospace have extremely high sealing and reliability.
Connectors are ubiquitous, from the mobile phones and computers we use daily to complex automotive electronic systems, aerospace equipment, communication base stations, and industrial automation production lines. In automobiles, connectors link the engine control unit, headlights, audio systems, and other components. In 5G base stations, they ensure stable signal transmission and facilitate high-speed communication.
