ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of The Invention
The present invention relates to a plug connector, and more particularly to a plug connector having an additional power harness assembly.
2. The Prior Art
A Universal Serial Bus (USB) is an existing data transmission standard. Many telecommunication devices, such as computers and peripherals thereof, utilize USBs for data transmission. USBs feature a higher data transmission speed than conventional RS232 connectors. Additionally, USBs reduce the required number of wire harnesses between devices thereby facilitating configuration of a system and maintenance thereof.
The standard USE connector includes four contact pins. Two contact pins are reserved for signal transmission and the other two are reserved for power transmission between devices. However, some applications require high rated power and an additional power plug is required. Since the additional power plug is assembled to an exterior of the connector, the power plug is vulnerable to damage caused by an undesired pulling force. Therefore, the present invention introduces an attaching arrangement for assembling the power plug to an interior of the plug connector.
SUMMARY OF THE INVENTION
Accordingly, the objective of the present invention is to provide a plug connector having additional power contact pins which provide power supply to a system requiring high rated power. The plug connector in accordance with the present invention can be applied to other cable harness assemblies, such as the IEEE 1394 connector.
To fulfill the above objective, a plug connector in accordance with the present invention comprises a first dielectric housing, a first connector, a second connector, a metal plate, a push button, a second dielectric housing, and a cable strain release cap. The first connector includes an EMI shield surrounding first and second insulators assembled together and receiving four contact pins therein. The first connector, the second connector, and the metal plate are inserted into corresponding channels defined through the first housing and extend beyond the mating face thereof. The second housing is assembled to the first housing and the cap engages with the second housing. When the plug connector is inserted into a panel of a computer system, a ground path is established from the housing of the computer system through the metal plate and the shield to the second connector. The second connector provides a path for signal transmission while the first connector is reserved for power transmission.
These and additional objectives, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiment of the invention taken in conjunction with the appended drawing figures.
