Connectors are a type of component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. Connectors are indispensable components in electronic equipment. If you follow the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc. For example, the connectors used for lighting on the court and the connectors for hard drives, as well as the connectors for igniting rockets, are very different. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly, continuously and reliably.

In general terms, connectors are not limited to current. In today's rapidly developing optoelectronic technology, in optical fiber systems, the carrier for transmitting signals is light, and glass and plastic replace the wires in ordinary circuits, but connectors are also used in optical signal paths, and their functions are the same as circuit connectors.
