Electrical connector with power terminals

A connector, comprising:

• a first body that includes a first main body portion, a first tongue and a second tongue, the first and second tongues being parallel with each other and extending forward from the first main body portion, wherein the first tongue has a first surface and a second surface opposite the first surface and a first width and the second tongue has a third surface and a second width that is less than the first width, the first tongue including a plurality of first receiving slots provided on the first and second surfaces and a plurality of second receiving slots provided on the third surface;
• a plurality of first terminals provided in the first receiving slots, each first terminals being provided with a mating portion in a plate shape and a soldering portion, the mating portions of the first terminals located on a first surface being offset relative to the mating portions on a second surface;
• at least two second terminals for transmitting power provided in the plurality of second receiving slots, each second terminals being provided with a mating portion in a plate shape and a soldering portion;
• and
• a cage mounted on the first body that forms a first mating chamber and a second mating chamber, the first mating chamber formed around and enclosing the first tongue and having a third width, the second mating chamber formed around and enclosing the second tongue and having a fourth width that is less than the third width, wherein the connector further comprises a first retention element fixed on the first body, the first retention element being provided with a plurality of perforations through which the soldering portions of the plurality of the first terminals and at least two second terminals are inserted, wherein the first retention element includes a base on which a plurality of first perforations for inserting the soldering portion of the first terminals are provided, and further includes a protrusion extending upward from the base, the protrusion including at least two second perforations for inserting the soldering portion of at least two second terminals are provided, the base of the first retention element having an upper and lower surface, each of the upper and lower surfaces of the base having a clasp portion provided thereon, and wherein the protrusion comprises a vertical wall extending upward from the rear end of the upper surface of the base, a top plate extending forward from the top end of the vertical wall, and a partition plate extending downward from the bottom of the top plate, and at least one said second perforation is provided at each of the two sides of the partition plate on the vertical wall.
