Abstract

A splice casing assembly for an elongated splice housing assembly and associated fiber optic cables includes a mounting insert disposed within a substantially tubular casing. A particularized mounting insert is characterized by a rectangular platform portion for supporting the splice housing assembly and by disklike end portions for positioning the insert within the tubular casing. Each of a pair of casing plugs comprises a threaded portion for fastening the plug at an end of the tubular casing and a tapered portion into which a fiber optic connector is threaded. Each of the connectors, a pair are included, comprises a threaded portion, a hexagonal gripping portion, a major cylindrical portion, and a minor cylindrical portion disposed between the hexagonal gripping portion and the major cylindrical portion. The casing assembly is configured so that fiber optic cables, supported by the connectors, may be routed through the connector, through the plug casings and into the splice housing assembly.

Claims

1. A splice casing assembly for a fiber optic splice housing assembly, the casing assembly comprising:

a tubular splice casing,

an elongated mounting insert disposed within the casing and for supporting a splice housing assembly,

a pair of casing plugs, each individually fastened at an opposite end of the tubular casing, and

a pair of connectors for fiber optic cables, each of the connectors individually fastened at a respective end of an associated casing plug, whereby each of a pair of fiber optic cables may be routed in a mating fashion via an associated connector, through an associated casing plug and into an end of the fiber optic splice housing assembly, said splice housing assembly to be surrounded by the tubular casing.

2. A splice casing assembly as defined in claim 1 wherein the mounting insert is comprised of an elongated, rectangular platform portion and integral disklike portions disposed at opposite ends of the platform portion.

3. A splice casing assembly as defined in claim 2 wherein the disklike portions exhibit central apertures for the axial insertion of a fiber optic cable.

4. A splice casing assembly as defined in claim 1 wherein the casing plugs each comprise a threaded portion for fastening to the splice casing.

5. A splice casing assemply as defined in claim 4 wherein the casing plugs each comprise a tapered portion narrowing in a direction away from the threaded portion.

6. A splice casing assembly as defined in claim 5 wherein each of the casing plugs comprises an intermediate portion disposed between the threaded portion and the tapered portion, said intermediate portion characterized by a diameter larger than the diameter of the threaded portion.

7. A splice casing assembly as defined in claim 6 wherein each of the casing plugs further comprises an aperture for the insertion of a fiber optic cable.

8. A splice casing assembly as defined in claim 1 wherein each of the connectors comprises a threaded portion for fastening to the casing plugs, a polygonal gripping portion, a major cylindrical portion, and a minor cylindrical portion disposed between the polygonal gripping portion and the major cylindrical portion.

9. A splice casing assembly as defined in claim 8 wherein each of the connectors exhibits an aperture for the insertion of a fiber optic cable.

10. A splice casing assembly for a fiber optic splice housing assembly, the casing assembly comprising:

a tubular splice casing,

a mounting insert disposed within the splice casing and for supporting a splice housing assembly, the mounting insert comprising an elongated, rectangular platform portion and integral disklike portions disposed at opposite ends of the platform portion,

a pair of casing plugs, each individually fastened at an opposite end of the splice casing, said casing plugs each comprising a threaded portion for fastening to the splice casing, and

a pair of connectors for fiber optic cables, each of the pair individually fastened at a respective end of a casing plug and comprising a threaded portion for fastening to the casing plug, a polygonal gripping portion, a major cylindrical portion, and a minor cylindrical portion disposed between the polygonal gripping portion and the major cylindrical portion, whereby each of a pair of fiber optic cables may be routed in a mating fashion via an associated connector, through an associated casing plug and into an end of the fiber optic splice housing assembly, said splice housing assembly to be surrounded by the tubular casing.

11. A splice casing assembly as defined in claim 10 wherein each of the disklike portions exhibits a central aperture for the axial insertion of a fiber optic cable.

12. A splice casing assembly as defined in claim 10 wherein each of the casing plugs comprises a tapered portion narrowing in a direction away from the threaded portion.

13. A splice casing assembly as defined in claim 12 wherein each of the casing plugs comprises an intermediate portion disposed between the threaded portion and the tapered portion, said intermediate portion characterized by a diameter larger than the diameter of the threaded portion.

14. A splice casing assembly as defined in claim 10 wherein each of the connectors exhibits an aperture for the insertion of a fiber optic cable.

15. A splice casing assembly as defined in claim 14 wherein each of the casing plugs comprises a tapered portion narrowing in a direction away from the threaded portion.

16. A splice casing assembly as defined in claim 15 wherein each of the casing plugs comprises an intermediate portion disposed between the threaded portion and the tapered portion, said intermediate portion characterized by a diameter larger than the diameter of the threaded portion.
