Abstract: A plug connector includes a plug housing having a plurality of side walls forming a cavity, a spacer having a plate shape and dividing the cavity into a pair of halves, a plurality of conductive terminals disposed on opposite sides of the spacer, a connector engagement component, and a pull tab. The connector engagement component has a first engagement portion releasably engaging a second engagement portion of a socket connector and a fixing portion detachably secured to the side walls of the plug housing. The pull tab is movable between the plug housing and the connector engagement component in a direction towards or away from a cable connected to the conductive terminals. Pulling of the pull tab in a pulling direction towards the cable enables release of an engagement between the first engagement portion and the second engagement portion, separating the plug connector from the socket connector.
