Patent ID: 7261128

Claim:
A hand-held wire-wrapping or unwrapping gun, comprising: a) a frame having user-accessible electrically-conductive elements, b) a rotatable drive assembly journaled on said frame and including an electrically-conductive drive shaft coupled at a distal end to means for receiving and removably holding an electrically-conductive bit for wrapping or unwrapping a wire around an electrical terminal, c) user-actuating means for driving the drive shaft and bit, d) means for electrically-insulating the frame from the electrically-conductive drive shaft and the electrically-conductive bit, the means for electrically-insulating the frame comprising an electrically-insulated drive housing surrounding the drive shaft and bit and separating the latter from the frame's electrically-conductive elements, the means for electrically-insulating the frame further comprising divided drive shaft portions and electrically-insulated means for coupling together the divided drive shaft portions, such that electrical shock to the user is avoided upon accidental contact between the user and one of the electrically-conductive elements of the frame when the tool bit during use contacts an electrically active electrical terminal.
