Abstract
Abstract A power supply includes a preformed case of electrically nonconductive material. Mounting bosses are integrally formed in the case to provide mounts for the power supply and mounting surfaces for active components of the power supply. Integral internal partitions and brackets mount various active components of the power in proper relationship in the case and provide electrical insulation where desired.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A power supply, including: a. a core and coil unit; b. a capacitor; c. a case formed of relatively rigid, electrically nonconductive material, said case including a base wall and a plurality of side walls integrally formed to provide a chamber; d. a partition integrally formed in said case dividing said chamber into a first section having said core and coil mounted therein, and a second section having said capacitor mounted therein; said partition including a channel open to said first section; e. at least one mounting boss integrally formed in said case in register with said channel; and f. a grounding conductor for said core and coil received in said at least one mounting boss and said channel.
Claim 2
Dependent Claim
119 words
A power supply, including: a. a core and coil unit; b. a capacitor; c. a case formed of relatively rigid, electrically nonconductive material, said case including a base wall and a plurality of side walls integrally formed to provide a chamber; d. a partition integrally formed in said case dividing said chamber into a first section having said core and coil mounted therein, and a second section having said capacitor mounted therein; said partition including a channel open to said first section; e. at least one mounting boss integrally formed in said case in register with said channel; and f. a grounding conductor for said core and coil received in said at least one mounting boss and said channel.
Claim 3
Dependent Claim
68 words
A power supply as set forth in claim 1 wherein: said partition extends from one side wall and includes a flange extending into said first section in spaced relationship with the opposite wall; and a footing extends into said first section generally in alignment with said flange; said flange and said footing serving to assure that said core and coil unit is spaced from said opposite side wall.
Claim 4
Dependent Claim
51 words
A power supply as set forth in claim 2 wherein; bracket means are formed integrally with said housing and positioned in the space between said core and coil unit and said opposite side wall to mount at least one additional operative component in spaced relationship to said core and coil unit.
Claim 5
Dependent Claim
47 words
A power supply as set forth in claim 2, further including: a plurality of mounting bosses integrally formed in said housing; at least a first of bosses and said footing having support surfaces spaced from said base wall in interfering relationship with said core and coil unit.
Claim 6
Dependent Claim
98 words
A power supply including: a. a preformed case of electrically non-conductive material, including a base wall and spaced apart side walls providing a chamber receiving active components of the power supply; b. a plurality of bosses integrally formed in said case and extending into said chamber, at least some of said bosses forming mounting surfaces engaging active components of the power supply; at least some of said bosses having recesses formed therein and exposed to the exterior of said case; and d. threaded lugs firmly received in said recesses for attachment of said case to a supporting member.
Claim 7
Dependent Claim
98 words
A power supply including: a. a preformed case of electrically non-conductive material, including a base wall and spaced apart side walls providing a chamber receiving active components of the power supply; b. a plurality of bosses integrally formed in said case and extending into said chamber, at least some of said bosses forming mounting surfaces engaging active components of the power supply; at least some of said bosses having recesses formed therein and exposed to the exterior of said case; and d. threaded lugs firmly received in said recesses for attachment of said case to a supporting member.
Claim 8
Dependent Claim
66 words
A power supply as set forth in claim 5 wherein; said case includes at least one integrally formed partition for assuring physical separation of at least two active components of said power supply; said partition including an offset portion providing an elongated recess in alignment with one of said bosses; and a grounding conductor mounted in said one of said bosses and received in said recess.
Claim 9
Dependent Claim
57 words
A power supply as set forth in a claim 6 wherein; said at least one partition includes a main portion and at least one flange portion angled with respect to said main protion and spaced from a corresponding side wall to assure that the active component received adjacent said partition is spaced from said corresponding side wall.
Claim 10
Dependent Claim
59 words
A power supply as set forth in claim 6 wherein; said offset portion of said partition is a pre-determined distance form one of said side walls; and said partition also includes a flange portion extending in the same direction as said offset portion at substantially the same predetermined distance from the sidewall opposite said one of said side walls.
Claim 11
Dependent Claim
30 words
A power supply as set forth in claim 5, wherein; bracket means are formed integrally with at least one of said side walls for mounting at least one active component.
Claim 12
Dependent Claim
26 words
A power supply as set forth in claim 5, further including: a preformed cover overlying the edges of said side walls remote from said base wall.
