Abstract:
1. A cordless power supply comprising: a direct current power source and a power conversion unit, said power conversion unit converts direct current; said direct current power source releasably coupled to said power conversion unit with a quick disconnect fitting; said quick disconnect fitting comprising first and second intermatable coupling halves, said first and second halves of said quick disconnect fitting being coupled or uncoupled; said second coupling half being integral with said direct current power source; said first coupling half comprises a first intermediate coupling half and a second intermediate coupling half; said first intermediate coupling half of said first coupling half being affixed to said power conversion unit, said first intermediate coupling half having second intermediate coupling half engaging surfaces and electrical conductors for communicating electrical power and information between said second intermediate coupling half engaging surfaces and said power conversion unit; said second intermediate coupling half of said first coupling half having a first connecting fixture allowing it to be mechanically and electrically coupled to and uncoupled from said first intermediate coupling half and said power conversion unit; said second intermediate coupling half of said first coupling half having a second connecting fixture providing a tool side connection mechanically and electrically coupled to and uncoupled from said second coupling half and said direct current power source; said second intermediate coupling half of said first coupling half having electrical conductors communicating electrical power and information between said first and second connecting fixtures, said first intermediate coupling half, said power conversion unit, said second coupling half, and said direct current power source; said second coupling half including first coupling half engaging surfaces having second electrical conductors for communicating electrical power and information between said first coupling half engaging surfaces and said direct current power source; such that, when coupled, said first and second coupling halves allow electrical power and information to be communicated between said power conversion unit and said direct current power source.
