Plug connector

A plug connector mounted on a printed circuit board, comprising:

• a lower terminal module, including a lower insulator and a plurality of lower terminals, each of the lower terminals having a lower fixing portion, a front of the lower fixing portion being drawn downward to form a lower contact portion beyond a bottom face of the lower fixing portion, the lower fixing portions of the lower terminals being integratedly molded in the lower insulator and arranged transversely, each lower contact portion beyond a bottom face of the lower insulator, a rear of each lower fixing portion extending rearwards to form a lower solder portion beyond a rear of the lower insulator;
• an upper terminal module engaged with the lower terminal module, the upper terminal module including an upper insulator and a plurality of upper terminals, each of the upper terminals having an upper fixing portion, a front of the upper fixing portion being drawn upwards to form an upper contact portion beyond a top face of the upper fixing portion, the upper fixing portions of the upper terminals being integratedly molded in the upper insulator and arranged transversely, each upper contact portion beyond a top face of the upper insulator, a rear of each upper fixing portion extending rearwards to form a upper solder portion beyond a rear of the upper insulator;
• and
• an insulating housing integratedly molded outside the lower terminal module and the upper terminal module, each lower contact portion exposed from a bottom face of the insulating housing, each upper contact portion exposed from a top face of the insulating housing.
