Abstract: The present invention provides a connector capable of preventing contacts from being touched by fingers or things through an opening of a connector housing, and of thereby improving connection reliability. A plug connector comprising a connector housing and PCB having contacts contained in the connector housing with a contacting surface exposed at one end and which functions as an interface capable of transmitting electric signal or light signal by being fitted to a receptacle connector to connect respective contacts to each other, characterized in that a shutter is provided as a part of a bottom wall of the connector housing to be freely opened or closed at a position covering the contacts formed in PCB, and that, before fitting of the connector, the shutter is in a closed state, and during and after fitting of the connector, the shutter is in a opened state.
