Conductive Boot for Power Tool Protection

摘要

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.

主权项

1. A power tool assembly comprising:
a power tool comprising a housing which encloses at least an electrical load and a control electronics module 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 module, the first shield open at a battery pack receiving slot of the housing; 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 module; 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.
