Patent ID: 7625243

Claim:
An electrical plug compatible to version 2.0 Universal Serial Bus (USB) standard, comprising: an insulative housing defining an elevated rear portion and a mating portion extending forwardly from the rear portion, the mating portion having a mating surface divided into a first mating section and a second mating section along a rear-to-front direction; a plurality of first passageways extending from the rear portion to the first mating section and in communicating to the mating surface; a depression defined in the second mating section; a first set of contacts received in the first passageways, and each having an elastic contact portion movably extending beyond the mating surface; and a second set of contacts each having a stiff contact portion securely retained in the depression; wherein the stiff contact portion and the elastic contact portion are located on a same side of the mating portion in condition that the elastic contact portion is located behind the stiff contact portion along the rear-to-front direction; wherein the second set of contacts are USB contacts; wherein a dimension of the mating portion is defined according version 2.0 USB standard; wherein a length of the mating portion is substantially the same as that of a standard version 2.0 type-A USB plug, wherein the stiff contact portion is flat shaped and substantially coplanar with the mating surface of the insulative housing, and wherein the depression is recessed from the mating surface and doesn't extend through the mating portion along a vertical direction perpendicular to the rear-to-front direction, wherein the second set of contacts each comprises a second tail portion parallel to and longer than the stiff contact portion, the second tail portion and the stiff contact portion being located on different horizontal planes, and wherein the second tail portion is located below the stiff contact portion; wherein the second mating section defines a plurality of second passageways under the depression, the second passageways extending backwardly through the rear portion of the insulative housing, and wherein the first set of contacts are assembled to the first passageways along the rear-to-front direction, and the second tail portions are received in the second passageways along a front-to-rear direction, wherein the mating portion includes a front distal end with the second passageways recessed backwardly from the front distal end, wherein the first set of contacts each includes a first tail portion extending backwardly from the elastic contact portion, the fist tail portion being located over the second tail portion while the first tail portion being located essentially coplanar with the stiff contact portion.
