Abstract

Abstract A vehicle having an internal storage battery and a body panel is provided with electrical connectors or fittings having portions extending through first and second openings in the body panel. Each fitting includes a conducting stem having an axial recess therein and includes an insulator head abutting one side of the body panel. One fitting has an insulator to prevent conduction between the stem and the body panel. Each threaded stem passes through an opening and receives a nut to clamp the insulator head against the body panel. A conductor extends from one stem to one pole of the internal storage battery. The other fitting is similar but is not insulated. Rather, it is electrically connected to the body panel or may have a conductor extending from the stem to the other pole of the internal storage battery. The fitting recesses receive electrical conductors in an exterior electrical circuit that may extend to another, external storage battery. There can be electrical transmission from the internal storage battery to the external storage battery or vice versa. Normally, the fitting recesses are protected by safety plugs readily removable when the device is to be used.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 196 words
An electrical connector for a vehicle having a storage battery and a body panel with first and second openings therein comprising a first conducting stem having an axial recess therein, an insulator head on said first stem having one portion of a size to abut one side of said panel and having another portion of a size to pass into said first opening, first threads on said first stem of a size to pass through said first opening, a first nut rotatable on said first threads and disposed on the other side of said panel, first means for establishing electrical continuity between said first stem and one pole of said storage battery, a second conducting stem having an axial recess therein, a second enlarged insulator head on said second stem of a size to abut said one side of said panel around said second opening, second threads on said second stem of a size to pass through said second opening, a second nut rotatable on said second threads and disposed on said other side of said panel, and second means for establishing electrical continuity between said second stem and the other pole of said storage battery.
Claim 2
Dependent Claim 196 words
An electrical connector for a vehicle having a storage battery and a body panel with first and second openings therein comprising a first conducting stem having an axial recess therein, an insulator head on said first stem having one portion of a size to abut one side of said panel and having another portion of a size to pass into said first opening, first threads on said first stem of a size to pass through said first opening, a first nut rotatable on said first threads and disposed on the other side of said panel, first means for establishing electrical continuity between said first stem and one pole of said storage battery, a second conducting stem having an axial recess therein, a second enlarged insulator head on said second stem of a size to abut said one side of said panel around said second opening, second threads on said second stem of a size to pass through said second opening, a second nut rotatable on said second threads and disposed on said other side of said panel, and second means for establishing electrical continuity between said second stem and the other pole of said storage battery.
Claim 3
Dependent Claim 15 words
A device as in claim 1 in which said second means includes said body panel.
Claim 4
Dependent Claim 31 words
A device as in claim 1 in which said first conducting stem and said second conducting stem are both in locations substantially remote from hydrogen gas discharged by said storage battery.
Claim 5
Dependent Claim 18 words
A device as in claim 1 including insulating plugs frictionally engageable with said stems in said axial recesses.
Claim 6
Dependent Claim 25 words
A device as in claim 1 including an insulating washer disposed on said first conducting stem and interposed between said panel and said first nut.
