Abstract

An electrical plug connector includes an insulated housing, a plurality of upper-row plug terminals, a plurality of lower-row plug terminals, and a rear terminal organizer. The insulated housing includes a rear assembling portion defined at the rear of the insulated housing. The rear terminal organizer is assembled to the rear of the insulated housing. The rear terminal organizer includes a plurality of through holes and a buckling portion. The through holes are defined through the rear terminal organizer from the front to the rear. The rear of the upper-row plug terminals and the rear of the lower-row plug terminals respectively pass through the through holes. The buckling portion is defined at the front of the rear terminal organizer. The buckling portion is adapted to be mated and engaged with the rear assembling portion.

First claim
