Abstract
A connection for a mineral insulated metal sheathed cable, wherein the connection employs a compression fitting. The connection may make up two or more mineral insulated metal sheathed cables wherein one or more of the cables may be secured with a compression fitting. The connection may splice together two individual cables, or a cable to an electrical element.
Claims25
A splice assembly for a mineral insulated metal sheathed cable comprising:
- a cable assembly comprising a first conducting element and mineral insulation disposed on the first conducting element;
- a connection between the first conducting element with a second conducting element;
- a compression fitting affixed to the cable assembly;
- and
- a coupling mechanically affixed to the compression fitting and in securing engagement with the second conducting element.
A method of forming a spliced connection for a cable assembly comprising mineral insulated metal sheathed cable assembly comprising:
- sliding an annular coupling body onto the cable assembly, wherein the coupling body includes a compressive fitting and the cable assembly comprises a first electrically conducting element;
- forming a connection between the first electrically conducting element and a second electrically conducting element;
- positioning the coupling body over the connection;
- and
- activating the compressive fitting thereby affixing the coupling to the mineral insulated metal sheathed cable assembly.
An apparatus for splicing a mineral insulated metal sheathed cable assembly comprising:
- an annular coupling body comprising a sleeve having an outer surface and an inclined portion on the outer surface;
- a connection formed by joining a first electrically conducting wire and a second electrically conducting wire, wherein the connection is disposed within the body;
- mineral insulation disposed on the first electrically conducting wire and a sheath on the insulation thereby forming a cable assembly, wherein at least a portion of the cable assembly extends into the body;
- and
- a swage member slidingly positioned on the inclined portion of the sleeve outer surface inwardly deforming the sleeve into compressive engagement with the cable assembly and affixing the cable assembly within.
