Connector, also known as CONNECTOR. Also known as connectors, plugs, and sockets in China. Generally refers to electrical connectors. The device that connects two active devices, transmitting current or signal, is a component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a communication bridge between blocked or isolated circuits within the circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function. Connectors are essential components in electronic devices, and when observed along the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing, and 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, the connectors for hard drives, and the connectors for igniting rockets are very different. However, regardless of the type of connector, it is necessary to ensure smooth, continuous, and reliable flow of current. In general, connectors are not limited to the current they connect to. In today's rapidly developing optoelectronic technology, the carrier for transmitting signals in fiber optic systems is light. Glass and plastic have replaced wires in ordinary circuits, but connectors are also used in the optical signal path, and their functions are the same as circuit connectors
