ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to a Universal Serial Bus (USB) electrical connector capable of providing a large amount of electrical power.
2. Description of Related Art
Some conventional Universal Serial Bus (USB) electrical connectors comprise first contacts and second contacts in an insulative housing for respectively transferring electronic data and electrical power. However, the first contacts and the second contacts are arranged near each other. Thus if high electrical power passes through the second contacts, signal interference will arise between the second contacts and the fire contacts. Nevertheless, users sometimes require much as 2.5 amps of electrical power.
In order to overcome this problem, users employ two different connectors for respectively transferring electronic data and electrical power. This solution runs against the trend toward miniaturization of electrical connectors and of computers generally.
Hence, an improved USB connector is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide an electrical connector capable of providing high electrical power and electronic data without generating signal interference.
To fulfill the above-mentioned object, an electrical connector of the present invention comprises an insulative housing, and a plurality of first contacts and at least a second contact respectively received within the housing. The first contacts have first body portions aligned with each other in a plane, and the second contact has a second body portion. The second body portion is spaced from the plane by the housing. The second contact is thereby able to transfer high electrical power without creating signal interference between the first contacts and the second contact.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when taken in conjunction with the accompanying drawings.
