Conductive boot for power tool protection
First Claim
1. A power tool assembly comprising:
- a power tool comprising a housing which encloses at least an electrical load and a control electronics circuit to activate the electrical load, the housing comprising a first shield as a layer of conductive material that nominally encloses the electrical load and the control electronics circuit, the first shield open at a battery pack receiving slot of the housing, wherein an antenna slot extends through the layer of conductive material forming the first shield in the housing, the antenna slot sized to facilitate passage of wireless control signals within a predetermined frequency range from a remote user interface to the control electronics circuit, the wireless control signals operating to selectively activate the electrical load;
a removable battery pack mateable with the battery pack receiving slot of the housing to supply electrical power for use by the electrical load and the control electronics circuit; and
a removable boot adapted to surround the removeable battery pack upon engagement with the housing, the boot comprising a second shield as a layer of conductive material which, which installed onto the boot, combines with the first shield to form a combined shield that nominally encloses the power tool and the boot, the boot comprising at least one locking feature that engages a corresponding feature of the housing to mechanically secure the boot to the housing to retain the boot in said engagement with the housing.

Abstract
Apparatus configured for high voltage power line maintenance and repair. In some embodiments, a power tool has a housing that encloses an electrical load and a control electronics module, the housing having a first shield layer of conductive material and being open at one end to receive a removable battery pack. A conductive boot removably attaches to the housing to surround the battery pack, the boot having a second shield layer of conductive material which, when installed onto the boot, combines with the first shield layer to form a combined shield that nominally encloses the power tool and the boot. A locking feature interlocks the boot to the housing. In further embodiments, the power tool is supported at a distal end of an insulated hot stick. A user interface is supplied at a proximal end of the hot stick to selectively activate the power tool.
