Abstract
Abstract A Universal Serial Bus plug connector consists of a lower shielding shell defining an opened top about a rear portion thereof. A dielectric body mounted with a number of contacts is mounted to the lower shielding shell, wherein a terminal portion of the contacts for connecting with leads of a cable is located under the opened top. An upper shielding shell has a top wall covering the opened top of the lower shielding shell, and two first side walls connected with two second side walls of the lower shielding shell, wherein each first side wall defines a locking hole through which a locking key defined by each second side wall extends. Each locking hole has a width which is sufficiently larger than that of each locking key. A retaining member consisting of a pair of jaws is integrally formed at a rear side of the upper shielding shell. The jaws are moved to each other to securely clamp the cable therebetween.
