BATTERY PACK

摘要

A battery pack (12) can be carried by a person and has a connector (44) to which a power cord (86) of a tool or appliance may be detachably connected. The battery pack (12) has a socket (44) which can accept conventional (low current) cigar lighter socket-compatible plugs (48) and a new (high current) plug (42). Means (90), (102) are provided to prevent a conventional cigar lighter plug (96) being actuated if it is inserted in the socket (44). The plug (42) is provided with means (120) which prevent it being actuated if it is inserted in a conventional cigar lighter socket. A power tool (80') or appliance can be connected to the power pack (12) by a self-retractable power cord (86). The self-retractable feature helps keep the power cord (86) away from the operating portion of a power tool (80').
