Abstract

Abstract A combination electrical distribution and power supply unit for recreational vehicles utilizing both AC and DC circuits wherein distribution apparatus such as circuit breakers, fuses, relays and the like are housed within one chamber of the unit, while the major heat generating components, such as a power converter transformer, are housed in a separate chamber of the unit separately ventilated and cooled. The apparatus is manufactured, shipped and installed as a unit, and includes quick attachment electrical receptacles permitting the unit to be readily connected to the recreational vehicle electrical system. The assembly includes cover plates and a hinged door wherein the unit may be mounted in a wall for access to the distribution components from the vehicle passenger compartment, and the power converter portion of the unit is accessible at the rear of the unit, and is located within the vehicle trunk or other nonoccupied vehicle compartment.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 311 words
A combination distribution panel and power converter unit for recreational vehicles including AC and DC distribution circuits and power converter apparatus characterized by the ability of the unit to separate heat generating components from distribution components and permit access to the distribution circuits from within the vehicle interior and provide access to the power converter apparatus exteriorly from the vehicle interior comprising, in combination, a housing including a distribution portion and a power converter portion, said distribution portion including a primary partition, front extending sidewalls depending from said partition having flanged edges for mounting said housing within a vertical wall, said partition and sidewalls defining an electrical distribution apparatus receiving chamber, an AC circuit breaker mounted within said chamber having input terminals and output terminals, a DC distribution system within said chamber spaced from said circuit breaker having a supply conductor nd output conductors, receptacles mounted on said housing distribution portion respectively connected to said output terminals and said supply and ouput conductors, said power converter portion including rear extending sidewalls extending from said primary partition in the opposite direction therefrom with respect to said front extending sidewalls, a rear wall interconnecting said rear extending sidewalls in spaced relationship to said partition wherein said partition, rear extending sidewalls and rear wall define a power converter receiving chamber, a voltage reducing power converter transformer circuit within said power converter receiving chamber having a DC low voltage output, an electrical conductor connecting said low voltage output to said receptacles connected to said DC distribution system supply conductor, cover plate means mounted on said flanged edges disposed over said electrical distribution apparatus receiving chamber, an opening defined in said cover plate means providing access to said AC circuit breaker, and a door mounted upon said housing adjacent said flanged edges positional between open and closed positions selectively providing access to said housing distribution portion.
Claim 2
Dependent Claim 311 words
A combination distribution panel and power converter unit for recreational vehicles including AC and DC distribution circuits and power converter apparatus characterized by the ability of the unit to separate heat generating components from distribution components and permit access to the distribution circuits from within the vehicle interior and provide access to the power converter apparatus exteriorly from the vehicle interior comprising, in combination, a housing including a distribution portion and a power converter portion, said distribution portion including a primary partition, front extending sidewalls depending from said partition having flanged edges for mounting said housing within a vertical wall, said partition and sidewalls defining an electrical distribution apparatus receiving chamber, an AC circuit breaker mounted within said chamber having input terminals and output terminals, a DC distribution system within said chamber spaced from said circuit breaker having a supply conductor nd output conductors, receptacles mounted on said housing distribution portion respectively connected to said output terminals and said supply and ouput conductors, said power converter portion including rear extending sidewalls extending from said primary partition in the opposite direction therefrom with respect to said front extending sidewalls, a rear wall interconnecting said rear extending sidewalls in spaced relationship to said partition wherein said partition, rear extending sidewalls and rear wall define a power converter receiving chamber, a voltage reducing power converter transformer circuit within said power converter receiving chamber having a DC low voltage output, an electrical conductor connecting said low voltage output to said receptacles connected to said DC distribution system supply conductor, cover plate means mounted on said flanged edges disposed over said electrical distribution apparatus receiving chamber, an opening defined in said cover plate means providing access to said AC circuit breaker, and a door mounted upon said housing adjacent said flanged edges positional between open and closed positions selectively providing access to said housing distribution portion.
Claim 3
Dependent Claim 56 words
In a combination distribution panel and power converter unit as in claim 1, a secondary partition defined in said electrical distribution apparatus receiving chamber dividing said chamber into first and second chamber portions, said AC circuit breaker being located within said first chamber portion and said DC distribution system being located within said second chamber portion.
Claim 4
Dependent Claim 76 words
In a combination distribution panel and power converter unit as in claim 2, a first cover plate mounted on said flanged edges disposed over and enclosing said first chamber portion, an opening defined in said first cover plate, said AC circuit breaker being accessible through said opening, and a second cover plate mounted on said flanged edges disposed over and enclosing said second chamber portion, said DC distribution system being mounted upon said second cover plate.
Claim 5
Dependent Claim 67 words
In a combination distribution panel and power converter unit as in claim 3 wherein said second cover plate includes a bracket, said receptacles being mounted on said bracket, conductors connecting said DC distribution system to said receptacles, and an opening defined in a front extending sidewall in alignment with said receptacles permitting access to said receptacles when said second cover plate is enclosing said second chamber portion.
Claim 6
Dependent Claim 42 words
In a combination distribution panel and power converter unit as in claim 1, wherein said rear extending sidewalls include a bottom sidewall and a tOp sidewall vertically disposed above said bottom sidewall, and ventilation openings defined in said top and bottom sidewalls.
