Abstract

A plug connector includes a connector body defining a front mating cavity with a first inner side and a second inner side opposite to the first inner side, and a rear cable supporting platform with a first surface and a second surface opposite to the first inner side and a plurality of terminals. The terminals include two rows of contacting sections arranged along the first and second inner sides of the mating cavity and soldering legs extending to the platform to be welded to a cable. The soldering legs are arranged in one row and exposing to the first surface of the platform while the second surface of the platform has no soldering legs to be welded to the cable.
