Abstract
Abstract A splice case housing electrical splices between two cables where the splices are immersed in an oil sealant having a specific gravity greater than water. The case includes holes located above the splices for receiving the electrical cables. Since the oil is heavier than water, if water were to enter the splice case, it would be above the oil and splices, thereby causing a hydraulic force on the oil, causing an even more intimate seal of the oil around the splices.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
An electrical splice case including a container housing electrical wire splices, entry holes located above the position of the splices; the entry holes for receiving electrical cable; the improvement comprising: a fluid sealant received in said container and covering said splices, said fluid sealant being substantially a silicone oil having a specific gravity greater than 1, whereby if water should enter said container, the water will remain on top of said fluid sealant, placing hydraulic pressure on said fluid sealant, thereby increasing the intimacy of the seal on the splices.
Claim 2
Dependent Claim
90 words
An electrical splice case including a container housing electrical wire splices, entry holes located above the position of the splices; the entry holes for receiving electrical cable; the improvement comprising: a fluid sealant received in said container and covering said splices, said fluid sealant being substantially a silicone oil having a specific gravity greater than 1, whereby if water should enter said container, the water will remain on top of said fluid sealant, placing hydraulic pressure on said fluid sealant, thereby increasing the intimacy of the seal on the splices.
Claim 3
Dependent Claim
17 words
A splice case as set forth in claim 1, wherein said fluid sealant is an electrical insulator.
Claim 4
Dependent Claim
18 words
A splice case as set forth in claim 1, wherein said fluid sealant is substantially insoluble with water.
Claim 5
Dependent Claim
17 words
A splice case as set forth in claim 1, wherein said silicone fluid is methyl alkyl polysiloxane.
Claim 6
Dependent Claim
32 words
A splice case as set forth in claim 1, wherein said container includes a bottom pan and a top cover, said top cover having holes there through for receiving the electrical cable.
Claim 7
Independent Claim
91 words
A system for sealing electrical components from moisture comprising: a container, said container housing said electrical components; at least one entry hole for receiving an electrical cable in said housing; a fluid sealant received in said container and covering said electrical components, said fluid sealant being substantially a silicone oil having a specific gravity greater than 1, whereby if water should enter said container, the water will remain on top of said fluid sealant, placing hydraulic pressure on said fluid sealant, thereby increasing the intimacy of the seal on the components.
Claim 8
Independent Claim
91 words
A system for sealing electrical components from moisture comprising: a container, said container housing said electrical components; at least one entry hole for receiving an electrical cable in said housing; a fluid sealant received in said container and covering said electrical components, said fluid sealant being substantially a silicone oil having a specific gravity greater than 1, whereby if water should enter said container, the water will remain on top of said fluid sealant, placing hydraulic pressure on said fluid sealant, thereby increasing the intimacy of the seal on the components.
Claim 9
Dependent Claim
16 words
A system as set forth in claim 6, wherein said fluid sealant is an electrical insulator.
Claim 10
Dependent Claim
16 words
A system as set forth in claim 6, wherein said fluid is substantially insoluble with water.
Claim 11
Dependent Claim
16 words
A system as set forth in claim 8, wherein said silicone fluid is methyl alkyl polysiloxane.
Claim 12
Dependent Claim
35 words
A system as set forth in claim 6, wherein said housing includes a top cover and a bottom pan portion, said top cover having holes therein for receiving electrical cable connected to said electrical components.
