ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electrical connector for connecting an integrated circuit (IC) module, such as a central processing unit (CPU) module, to a power source.
2. The Prior Art
With the development of electronic industry, operation speed of CPUs is significantly increased. To support such a speedy operation, an independent power supply may be required for supplying stable electrical power to the CPU. Furthermore, to ensure a continuous supply of power, the mechanical structure of the power connector must be reliable. A lot of different connectors having complicated structures are available in the market. Such connectors may be modified to serve as a power connector. However, such complicated structures make them unreliable as compared to connectors having a simple structure. An example of the complicated power connectors is disclosed in the co-pending U.S. patent application Ser. No. 09/549,155 filed on Apr. 13, 2000 and assigned to the assignee of the present invention.
Furthermore, exchange of signals, including data and commands, between a CPU and other components of a computer also requires a connection between the CPU and the components. It is preferable to combining the signal connection in the power connector for reducing the amount of space occupied thereby.
It is thus desired to provide a power connector overcoming the problems discussed above.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a power connector having a simple and reliable structure for ensuring stable and continuous supply of electrical power to a CPU module.
Another object of the present invention is to provide a power connector in which a signal connector is incorporated for signal exchange between a CPU module and related components of an electronic device.
To achieve the above objects, a power connector in accordance with the present invention comprises an insulative housing defining an elongate slot in a front face thereof for receiving a central processing unit (CPU) module therein and pairs of upper and lower passages in an opposite face thereof in communication with the slot for receiving power contact pairs that electrically engage the CPU module. Each pair of power contacts includes a ground terminal and a hot terminal respectively received in the upper and lower passages. Each pair of ground and hot terminals have tail sections extending beyond the rear face and offset toward each other for securely receiving and electrically engaging a capacitor board to supply electrical power to the CPU module. Each lower passage is elongated in a direction away from the corresponding upper passage for providing an additional space to receive and retain a signal contact. Each signal contact has a tail section extending beyond the rear face for being electrically connected to a flat cable for exchange of data and control signals. Each signal contact has a U-shaped engaging section located in the slot and extending toward the CPU module for electrically engaging the CPU module and providing resiliency.
