Connector is a kind of component that our electronic engineers and technicians often contact. Its function is very simple: build a communication bridge between the blocked or isolated circuits in the circuit, so as to make the current flow and realize the predetermined function of the circuit. Connectors are indispensable components in electronic equipment. If you observe along the current flow path, you will always find one or more connectors. Connector forms and structures are ever-changing. There are various forms of connectors with different application objects, frequencies, power, application environments and so on.
