Circuit interconnect for a power tool
First Claim
1. A circuit interconnecting device for a power tool of the type having a compartment for a replaceable battery, the device comprising:
- a base means adapted for mounting in the battery compartment including power cord receiving means, and extension means receiving means, the base means including power tool asymmetrical engagement means for engaging an asymmetrical receiving means of the battery compartment, said engagement means being engagable with said receiving means only when the device is inserted into the battery compartment in a preferred orientation and otherwise preventing the full insertion of the device into the battery compartment;
an extension means, having a proximal end and a distal end, the proximal end adapted for plug-in engagement with the extension means receiving means, the distal end adapted for electrical interconnection with a pair of electrical contacts of the power tool, the proximal and distal ends being in electrical communication;
a power cord including, at one end, a plug for electrical interconnection with a power source socket, the other end adapted for engagement with the power cord receiving means of the base means such that engagement of the proximal end of the extension means with the extension means receiving means provides electrical interconnection between the power cord and the proximal end of the extension means whereby the device may be inserted into the battery compartment of the power tool to provide power from the power source socket to the power tool electrical contacts.

Abstract
A circuit interconnecting device for a power tool of the type having a compartment for a replaceable battery is provided. A base is adapted for mounting in the battery compartment. The base receives one end of a power cord and includes an extension that has a proximal end adapted for plug-in engagement with the base, and a distal end adapted for electrical interconnection with a pair of electrical contacts of the power tool. A power cord has at one end a plug for electrical interconnection with a power source socket, and at the other end is adapted for engagement with the base, such that an electrical interconnection between the power cord and the distal end of the extension is provided. A cover is mounted and slidably engaged with the extension in such a manner that the cover may be moved to expose contact surfaces of the distal end of the extension or to cover the contact surfaces to prevent electrical shock when the device is removed from the power tool. The base only fits into the bakery compartment in a preferred orientation to assure proper polarity of the device when inserted into the power tool.
