This application claims the priority benefit of Taiwan application serial no. 098223744, filed on Dec 18, 2009. The entirety of the above-mentioned patent application is incorporated herein by reference and made a part of this specification.
1. Technical Field
The present invention relates to an electrical connector, and more particularly to an electrical connector with a USB 2.0 interface and a USB 3.0 interface. At least two of the second terminals located at two sides of the USB 3.0 interface are bent outwardly at a predetermined angle, so that cross talk between adjacent two second terminals can be reduced.
2. Description of the Related Art
Currently, due to the plug and play function, peripheral devices with USB interfaces become popular. A data transfer rate provided by the USB 2.0 protocol may be as high as 480 Mbit/s. However, with the development of multimedia technology, it takes more than ten minutes if a multimedia file of 25 GB is downloaded with the USB 2.0 protocol and that may not satisfy consumers' demand. Therefore, the USB 3.0 protocol providing a data transfer rate as high as 4.8 Gbit/s is introduced, so that the time consumed for downloading the multimedia file of 25 GB with the USB 3.0 is one-tenth of the consumed time with the USB 2.0 protocol.
Generally, a conventional USB 2.0/USB 3.0 electrical connector has a plurality of solder joints, which are arranged parallel to each other and separated from each other with a fixed distance.
Therefore, it is necessary to design a new electrical connector that can overcome the above-mentioned shortcomings.
The present invention relates to an electrical connector with a USB 2.0 interface and a USB 3.0 interface. At least two of the second terminals located at the two sides of the USB 3.0 interface are bent outwardly at a predetermined angle, so that cross talk between two of the second terminals can be reduced.
The present invention also relates to an electrical connector, wherein the thickness of the solder portion is 1.20 millimeter, so that the cross talk between the second terminals located at two sides of the solder portion can be reduced.
The present invention provides an electrical connector. The electrical connector includes an insulating body, a plurality of first terminals, a plurality of second terminals and a shielding shell. One end of a base disposed on the insulating body has a first solder portion and a second solder portion, and another end of the base has a connection portion. The first terminals run through the base. The first terminals are arranged parallel to each other and located on two sides of the first solder portion and the connection portion. The second terminals run through the base. The second terminals are located on two sides of the second solder portion and the connection portion. At least two of the second terminals located on the two sides of the second solder portion are bent outwardly at a predetermined angle, so as to increase a distance between two adjacent second terminals and reduce cross talk between the two adjacent second terminals. The shielding shell sleeves on the connection portion and is used for reducing electromagnetic interference between the first terminals and the second terminals.
Other objectives, features and advantages of the present invention will be further understood from the further technological features disclosed by the embodiments of the present invention wherein there are shown and described preferred embodiments of this invention, simply by way of illustration of modes best suited to carry out the invention.

Referring to
The insulating body 10 can be made of insulating material, such as plastic, but not limited hereto. A base 11 is disposed on the insulating body 10. The base 11 includes a first solder portion 12, a second solder portion 13 and a connection portion 14. The first solder portion 12 and the second solder portion 13 are located on one end of the base 11 and the connection portion 14 is located on another end of the base 11. The thicknesses of the first solder portion 12 and the second solder portion 13 both can be 1.20 millimeter, but not limited hereto. The thicknesses of the first solder portion 12 and the second solder portion 13 are greater than that of the insulating sheet 110 of the conventional electrical connector 100, therefore the cross talk between the second terminals 30 on opposite sides of the second solder portion 13 can be reduced.
The plurality of first terminals 20 run through the base 11. The first terminals 20 are arranged parallel to each other and located on the two sides of the first solder portion 12 and the connection portion 14. The first terminals 20 can be USB 2.0 terminals, but not limited to, and the number of the first terminals 20 can be five.
The second terminals 30 also run through the base 11. The second terminals 30 are located on two sides of the second solder portion 13 and the connection portion 14. At least two of the second terminals 30 located on the two sides of the second solder portion 13 are bent outwardly at a predetermined angle, so as to increase a distance between two adjacent second terminals 30 and reduce cross talk between the two adjacent second terminals 30. The predetermined angle can be in the range from 25° to 40°, and is preferably 30°. The second terminals 30 can be USB 3.0 terminals, but not limited to, and the number of the second terminals 30 can be five.
The shielding shell 40 sleeves on the connection portion 14 and is used for reducing electromagnetic interference between the first terminals 20 and the second terminals 30. The shielding shell 40 can be made of metal.
As shown in
In summary, the electrical connector of the present invention has at least the following advantages. First, at least two second terminals 30 are bent outwardly at about 30° to increase the distance between the two adjacent second terminals 30, so the cross talk between the two adjacent second terminals 30 can be reduced. Second, the thickness of the second solder portion 13 is 1.20 millimeter, so the cross talk between the second terminals 30 on the opposite sides of the second solder portion 13 can be reduced. Therefore, the shortcomings of the conventional electrical connector can be overcome by the electrical connector of the present invention.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including configurations ways of the recessed portions and materials and/or designs of the attaching structures. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
