Abstract

An electrical connector assembly comprises a receptacle electrical connector and a plug electrical connector. The receptacle electrical connector includes a first body having a first and a second tongues and a plurality of first terminals, the first terminals located on opposite surfaces of the first tongue and offset relative to each other. The plug electrical connector includes a second body and a third and fourth mating chambers located in the second body; a plurality of third terminals, wherein the third terminals located on upper and lower sides of the third mating chamber are offset relative to each other. The receptacle electrical connector and the plug electrical connector can mate with each other so the first terminals and the third terminals are mated with each other to transmit signals and the second tongue and the fourth mating chamber are connected to transmit power.

Claims

1. 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 first and second mating chambers are in communication with each other.

2. The connector according to claim 1, wherein the first tongue comprises a base with a plate shape and two keying ribs protruding away from two sides of the base.

3. The connector according to claim 1, wherein two of the plurality of second terminals are configured to be connected to a negative power input and positive power input and wherein an end of the mating portion of the second terminal for connecting with the negative power input is located at a position closer to a front than an end of the mating portion of the second terminal for connecting with the positive power input.

4. The connector according to claim 1, wherein each of the second terminals comprises a fixing portion provided between the mating portion and the soldering portion, the soldering portions of the plurality of second terminals are bent and extended away from each other and from ends of the fixing portions such that a distance between the soldering portions is greater than a distance between the mating portions.

5. The connector according to claim 1, wherein the cage encloses the first tongue and the second tongue so as to form a first receiving chamber.

6. The connector according to claim 5, wherein the cage is configured to have an arching portion that forms the second mating chamber and a hole is provided on both sides of the arching portion.

7. The connector according to claim 5, 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.

8. The connector according to claim 5, wherein a clasp portion is provided on the cage, the connector further comprising a first retention element which is provided with a holding portion corresponding to the clasp portion such that the first retention element is fixed in the cage and abutted against the rear end of the first main body portion.

9. The connector according to claim 8, 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, each of upper and lower surfaces of the base including two holding portion.

10. The connector according to claim 9, 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.

11. The connector according to claim 8, wherein the first cage comprises a top plate, two opposite side plates and a bottom plate and each of the top plate and the bottom plate are provided with two clasp portions.

12. The connector according to claim 8, wherein the cage is configured to have an arching portion for forming the second mating chamber and a hole is provided on the left and right side of the arching portion respectively and one of the clasp portions is provided at each side of the arching portion.
