Connector is a kind of component that our electronic engineering technicians often contact. Its function is very simple: build a bridge of communication between the blocked or isolated circuits in the circuit, so that the current flows and the circuit realizes the predetermined function. A connector is an indispensable part in an electronic device. Observe the path of current flow and you will always find one or more connectors. The form and structure of the connector are ever-changing. With different application objects, frequency, power, application environment, etc., there are various types of connectors.
