DETAILED DESCRIPTION A removable auxiliary electrical component for an electrical device that can be removed when the electrical device is powered is disclosed.
The removable axillary electrical component includes a module located on an exterior portion of an electrical product.
The removable axillary electrical component also includes a guard member connected to an electrical product.
The electrical product includes an electrical contact portion connected to a power source of the electrical product, and a housing member containing a first electrical portion of the module.
The electrical portion includes a second contact portion, the second contact portion is used for mateably engaging the first contact portion.
The housing portion also includes a snap member for removable engagement with the exterior portion of the electrical product.
The present invention satisfies the need to quickly and easily remove and replace an electrical component that is on the exterior of a large product.
In a preferred embodiment, the component is a fan module, and the product is a computer that the fan module is assembled onto for cooling.
A feature of the present invention is that the fan module can be easily released from and reattached to the computer housing, and no additional labor is involved to make the electrical connection to power the fan during this process.
When the fan is removed from the housing, the electrical connection is simultaneously broken.
Further, when the fan is attached to the housing, the electrical connection is simultaneously reinstated.
Another feature of the present invention is that the fan module may be removed or attached while the computer is in operation.
A sheet metal cage covers the opening of the computer housing to prevent the user from inserting a hand or finger into the opening and subsequently getting an electrical shock.
The sheet metal cage also acts as an electromagnetic interference shield for the computer housing.
Also, the user cannot touch the "live" electrical contacts that connect the fan to the housing when the fan is removed
