Abstract

An electrical receptacle connector includes an insulated housing, upper-row receptacle terminals, and lower-row receptacle terminals. The insulated housing includes a base portion and a tongue portion extended from one side of the base portion. The tongue portion has an upper surface, a lower surface, and a front lateral surface. The lower-row receptacle terminals correspond to the upper-row receptacle terminals and include signal terminals which include high speed transmitting terminals. Each of the high speed transmitting terminals includes a bending portion, an extension portion, and a cutout portion. The bending portion is extended upward from the front end of the flat contact portion and inserted into the tongue portion, the extension portion is extended forward from the top of the bending portion toward the front lateral surface, and the cutout portion is defined at the extension portion and near to the bending portion.

First claim

What is claimed is:

1. An electrical receptacle connector, comprising:
a metallic shell, defining a receiving cavity therein;
an insulated housing received in the receiving cavity, wherein the insulated housing comprises a base portion and a tongue portion extended from one side of the base portion, wherein the tongue portion has an upper surface, a lower surface, and a front lateral surface, the upper surface is opposite to the lower surface;
a plurality of upper-row receptacle terminals comprising a plurality of signal terminals, at least one power terminal, and at least one ground terminal, wherein each of the upper-row receptacle terminals is held in the base portion and disposed at the upper surface; and
a plurality of lower-row receptacle terminals comprising a plurality of signal terminals, at least one power terminal, and at least one ground terminal, wherein each of the lower-row receptacle terminals is held in the base portion and disposed at the lower surface, wherein each of the lower-row receptacle terminals comprises a flat contact portion and a body portion, each of the body portions is held in the base portion, each of the flat contact portions is extended from one of two ends of the body portion and is disposed at the lower surface, wherein the signal terminals comprise a plurality of high speed transmitting terminals, each of the high speed transmitting terminals comprises a bending portion, an extension portion, and a cutout portion, wherein the bending portion is extended upward from the front end of the flat contact portion and inserted into the tongue portion, wherein the extension portion is extended forward from the top of the bending portion toward the front lateral surface, wherein the cutout portion is defined at the extension portion and near to the bending portion, and wherein a first distance defined between the flat contact portion of each of the high speed transmitting terminals of the lower-row receptacle terminals and the corresponding upper-row receptacle terminal is greater than a second distance defined between the top of the bending portion of each of the high speed transmitting terminals of the lower-row receptacle terminals and the corresponding upper-row receptacle terminal.

2. The electrical receptacle connector according to claim 1 , wherein the tongue portion defines a plurality of cutout holes each extended from the upper surface or the lower surface to the corresponding extension portion.

3. The electrical receptacle connector according to claim 1 , wherein the tongue portion defines a plurality of openings, each of the openings is formed at the front lateral surface, the extension portions are received in the openings, respectively.

4. The electrical receptacle connector according to claim 3 , further comprising a material band extended to each of the extension portion, the material band comprises a plurality of breaking portions received in the openings, respectively.

5. The electrical receptacle connector according to claim 1 , wherein the distance between the flat contact portion of each of the high speed transmitting terminals of the lower-row receptacle terminals and the front lateral surface is greater than the distance between the flat contact portion of the power terminal of the lower-row receptacle terminals and the front lateral surface.

6. The electrical receptacle connector according to claim 1 , wherein each of the upper-row receptacle terminals comprises a flat contact portion, a body portion, and a soldering portion, the body portion is held in the base portion, the flat contact portion is extended from one of two ends of the body portion and disposed at the upper surface, and the soldering portion is extended from the other end of the body portion and protruded from the base portion.

7. The electrical receptacle connector according to claim 1 , wherein each of the lower-row receptacle terminals comprises a soldering portion extended from the other end of the body portion and protruded from the base portion.

8. The electrical receptacle connector according to claim 1 , further comprising a grounding sheet, the grounding sheet is disposed at the insulated housing and is located between the upper-row receptacle terminals and the lower-row receptacle terminals.

9. The electrical receptacle connector according to claim 1 , wherein the upper-row receptacle terminals and the lower-row receptacle terminals have 180 degree symmetrical design with respect to a central point of the receptacle cavity as the symmetrical center.

10. The electrical receptacle connector according to claim 9 , wherein the position of the upper-row receptacle terminals correspond to the position of the lower-row receptacle terminals.
