Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A direct current battery connector comprising: a single electrical connector cable having a conductor for positive battery connection and a conductor for negative battery connection; a positive battery clamp and a negative battery clamp at one end of said cable each communicating with the conductor of said cable of similar polarity; a male electrical plug at the opposing end of said cable having positive and negative connections therein; and a safety switch which automatically breaks current flow when necessary attached to the negative conductor wire of said cable.
Claim 2
Dependent Claim
88 words
A direct current battery connector comprising: a single electrical connector cable having a conductor for positive battery connection and a conductor for negative battery connection; a positive battery clamp and a negative battery clamp at one end of said cable each communicating with the conductor of said cable of similar polarity; a male electrical plug at the opposing end of said cable having positive and negative connections therein; and a safety switch which automatically breaks current flow when necessary attached to the negative conductor wire of said cable.
Claim 3
Dependent Claim
25 words
The direct current battery connector according to claim 1 wherein said positive and negative battery clamps attach directly to said battery of said conventional vehicle.
Claim 4
Dependent Claim
39 words
The direct current battery connector according to claim 1 wherein said safety switch is attached to the negative conductor wire of said cable near said male electrical plug and is a conventional circuit breaker that breaks upon reverse polarity.
