[0002] Electronic connectors are also often called circuit connectors, electrical connectors, and conductor devices that bridge two conductors on a loop so that current or signals can flow from one conductor to another. It is widely used in various electrical circuits to connect or disconnect current or signals. This connection may be pluggable at any time, or it may be a permanent node between electrical equipment or wires. Electronic connectors are devices that transmit electronic signals (analog signals or digital signals) and can provide a separate interface to connect two sub-electronic systems. They are components used to complete electrical connections between circuits or electronic machines, such as power plugs / sockets, IC pins, telephone line plugs, etc.
