Abstract

A portable power tool for forming wire wrap type connections includes an electric motor, a torque transmitter and a casing for enclosing the electric motor and the torque transmitter. Removably mounted to the casing is a battery pack. The battery pack mounts both rechargeable and non-rechargeable batteries so that the battery charger may not be recharged in a physically compatible battery pack when non-rechargeable batteries are contained within the battery pack.

Claims

1. A battery operated wire wrapping tool power system comprising in operative combination:

a battery charger;

an electric motor;

means for transmitting torque from said electric motor to a wire wrapping bit;

a casing to enclose both the electric motor and the means for transmitting torque to said wire wrapping bit;

a battery pack constructed and arranged to be removably mountable within the battery operated wire wrapping tool to provide a handle for the battery operated wire wrapping tool, said battery pack having;

means for transmitting electrical energy from either rechargeable or non-rechargeable batteries to the battery operated wire wrapping tool;

means for mounting both rechargeable and non-rechargeable batteries within said battery pack, said means for mounting both rechargeable and non-rechargeable batteries within said battery pack constructed and arranged to prevent said battery pack from being placed in said battery charger when said battery pack contains non-rechargeable batteries by utilizing the difference in diameter of said batteries to distinguish the position of said rechargeable from said non-rechargeable batteries.
