The connector is the CONNECTOR. Also known as connectors, plugs, and sockets in China. Generally refers to connectors. A device that connects two active devices to transmit current or signals. It is widely used in military systems such as aviation, aerospace, and national defense. The connector is a component that our electronic engineering technicians often come into contact with. The SIM card holder connector is a commonly used smaller connector used in electronic products such as mobile phones and computers. Its effect is very simple: building a bridge for communication between blocked or isolated circuits within the circuit, thereby allowing the current to flow and complete the intended function of the circuit. Connectors are essential components in electronic devices, and when investigating the path of current flow, you will always find one or more connectors. The ways and structures of connectors are ever-changing, and there are various types of connectors depending on the application target, frequency, power, and environment. 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 connection and reliable flow of current. In general, connectors are not limited to electrical currents. In today's rapidly developing optoelectronic technology, the carrier of signals in optical fiber systems is light. Glass and plastic have replaced wires in general circuits, but connectors are also used in optical signal pathways, and their effects are the same as circuit connectors.
