Abstract

An electrical plug connector includes an insulated housing and a rear terminal organizer. The rear terminal organizer is assembled to the rear of the insulated housing. The rear terminal organizer includes a base and a gluing passage. The front of the base corresponds to the rear of the insulated housing. The width of the base is greater than the width of the insulated housing. The periphery of the base is protruded from the periphery of the insulated housing. The gluing passage is formed at a peripheral area of the base, and the gluing passage is defined through the base from the front to the rear.
