Claim Text:
1. A plug connector, comprising a plug housing, a plug retaining seat, a row of plug power contacts and a row of plug signal contacts; wherein the plug housing having a mating portion located on the front of the plug housing and a mounting portion located on the rear thereof, a front surface of the mating portion being perpendicular to a bottom surface of the mounting portion, a front surface of the mating portion forming a row of parallel vertical plug power ports and one plug signal port located under the row of the plug power ports to form a stacked structure, the row of the plug power ports including at least one first plug power port and at least one second plug power port, the first plug power port forming a vertical middle plate therein, the plug signal port having an open bottom and having a top wall and two opposite sidewalls, the mounting portion forming a row of plug power contact-mounting cavities that include at least one first plug power contact-mounting cavity and at least one second plug power contact-mounting cavity, each of the plug power contact-mounting cavities forming two plug power contact-receiving passages that pass through a rear surface and the bottom surface of the mounting portion to receive and fix the plug power contacts, the plug power contact-receiving passages located in the first and second plug power contact-mounting cavity being respectively communicated with the first and second plug power ports; the mounting portion further forming a row of plug signal contact-receiving passages that are located on the bottom surface of the mounting portion and communicated with the plug signal port to receive the corresponding plug signal contacts; the plug retaining seat being drawer-shaped and having a bottom board, two opposite side boards and a rear board; the plug retaining seat being mounted on the mating portion of the plug housing to close the open bottom of the plug signal port and fix the plug signal contacts; each two adjacent plug power contacts having symmetrical structures and forming a group, each group being fixed in one plug power contact-mounting cavity, and each plug power contact being fixed in the corresponding plug power contact-receiving passage; each of the plug power contacts including an L-type connecting portion being vertical and blade-shaped, a vertical blade-shaped mating end being bent toward one side from a front end of the connecting portion and then horizontally extending forward, and a back end vertically extending downward from a bottom end of the connecting portion; wherein the mating end passes through the corresponding plug power contact-receiving passage to enter into the corresponding plug power port, the connecting portion is fixed in the plug power contact-receiving passage, and the back end extends out of the bottom surface of the mounting portion; and each of the plug signal contacts including a head horizontally extending forward, a tail being perpendicular to the head and vertically extending downward, and an L type retaining portion connecting the head and the tail; wherein the head is inserted into the plug signal port, one portion of the L type retaining portion is fixed in the plug signal contact-receiving passage, the other portion thereof is fixed in the plug retaining seat, and the tail extends out of the bottom surface of the mounting portion.
