Connector is one of the components that we electronic engineers and technicians often come into contact with. Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment, along the current flow path observation, you will always find one or more connectors. Connector form and structure is ever-changing, with the application object, frequency, power, application environment, etc., there are a variety of different forms of connectors. For example, the connector used to light a lamp on a ball field is very different from the connector used to light a hard disk drive, or the connector used to light a rocket. But no matter what kind of connector, it is important to ensure that the current flows smoothly and continuously and reliably.
In general terms, the connector is not limited to current, in the rapid development of optoelectronics technology today, fiber optic systems, the carrier of the signal is light, glass and plastic instead of ordinary circuits in the wire, but the optical signal pathway also use the connector, their role and the circuit connector is the same.
