Plug connector

Abstract

This invention relates to a plug connector, comprising an insulating body, a tongue plate fixed to the insulating body, and a locking mechanism located on the top of the insulating body. The tongue plate has a plurality of conductive terminals, and the locking mechanism includes a locking member and a pull strap. The locking member has a pull portion connected to the pull strap. The plug connector also has a protective cover assembled to the insulating body. The protective cover has a main body portion located on the upper side of the insulating body and a rear cover plate located on the rear side of the insulating body. The main body portion has a top cover plate that covers the pull portion from above and a pair of opposite side cover plates that cover the pull portion from both sides laterally. The rear cover plate has an opening for the pull strap to pass through rearward. This plug connector effectively prevents the locking member from being accidentally activated.
