Connector assembly including receptacle connector and plug connector, and plug connector
A connector assembly having a receptacle connector and a plug connector coupled thereto. The plug connector includes: a signal pin having one side in electrical contact with a signal line of a cable and the other side in elastic contact with a clip pin of the receptacle connector; a shield can enclosing the signal pin; a first insulating member coupled to the signal pin; and a plug shell enclosing an upper surface and a side surface of the shield can. The receptacle connector includes: a clip pin having a lower portion contacting a signal pad of a circuit board and an upper portion in elastic contact with the other side of the signal pin; a receptacle base installed on the circuit board and providing a space for the clip pin; and a second insulating member coupled to the clip pin and enclosing the side surfaces of the clip pin.
