Terminus adapter for fiber optic cables

Claim 2

An adapter for use with an optical fiber terminus and which allows for an effective environmental seal between a terminus and an optical fiber, said adapter comprising: an adapter body having first and second ends and an elongated optical fiber channel extending through said adapter body, wherein said elongated optical fiber channel is sized to receive optical fibers having a variety of sizes, and wherein said first end of said adapter body is operably connected to a rearward end of said terminus; and a plug, at least partially disposed within said second end of said adapter body, for forming an environmental seal with said adapter body, wherein said plug defines an aperture sized to snugly receive an optical fiber having a predetermined diameter such that an environmental seal is thereby also created between said plug and said optical fiber such that an overall environmental seal is maintained between the optical fiber and said terminus.

Claim 3

The adapter for use with an optical fiber terminus of claim 1 wherein said first end of said adapter body further comprises an insertion means for operably connecting to said rearward end of said terminus.

Claim 4

The adapter for use with an optical fiber terminus of claim 2 wherein said insertion means comprises a cylindrical protrusion for extending into the rearward end of said terminus.

Claim 5

The adapter for use with an optical fiber terminus of claim 3 wherein said cylindrical protrusion is sized to fit snugly within said rearward end of said terminus.

Claim 6

The adapter for use with an optical fiber terminus of claim 4 wherein said adapter body further comprises a shoulder adjacent said cylindrical protrusion and sized to abut against said terminus when the cylindrical protrusion is extended into the rearward end of said terminus.

Claim 7

The adapter for use with an optical fiber terminus of claim 1 wherein said plug has a first end disposed in said second end of said adapter body, and wherein the plug has a second end, opposite the first end, that is larger than said first end and which surrounds the second end of said adapter body.

Claim 8

The adapter for use with an optical fiber terminus of claim 6 wherein said plug is T-shaped in cross-section, and wherein the first end of said plug has a cylindrical protrusion extending into said elongated optical fiber channel.

Claim 9

The adapter for use with an optical fiber terminus of claim 1 wherein said plug is T-shaped in cross-section, and wherein the first end of said plug has a cylindrical protrusion extending into said elongated optical fiber channel.

Claim 10

An improved terminus assembly for the securement of an optical fiber with an environmental seal against ambient conditions, said terminus assembly comprising: a terminus having an outer wall and an interior central bore opening through a rearward end of said terminus to receive an optical fiber and which terminus is sized and shaped to extend into a multi-cavity connector; an adapter body having opposed forward and rearward ends and defining an elongated optical fiber channel extending therethrough which is adapted to receive optical fibers having a variety of sizes, wherein the forward end is sized to be snugly received within the interior central bore opening through the rearward end of said optical fiber terminus to thereby create an environmental seal between said elongated forward end of said adapter body and said rearward end of said optical fiber terminus; and a plug operably connected to said rearward end of said adapter body, wherein said plug defines an aperture sized to snugly receive an optical fiber having a predetermined diameter to thereby also create an environmental seal between said plug and said optical fiber such that an overall environmental seal is maintained between the optical fiber and said optical fiber terminus.

Claim 11

An improved terminus assembly for the securement of an optical fiber with an environmental seal against ambient conditions, said terminus assembly comprising: a terminus having an outer wall and an interior central bore opening through a rearward end of said terminus to receive an optical fiber and which terminus is sized and shaped to extend into a multi-cavity connector; an adapter body having opposed forward and rearward ends and defining an elongated optical fiber channel extending therethrough which is adapted to receive optical fibers having a variety of sizes, wherein the forward end is sized to be snugly received within the interior central bore opening through the rearward end of said optical fiber terminus to thereby create an environmental seal between said elongated forward end of said adapter body and said rearward end of said optical fiber terminus; and a plug operably connected to said rearward end of said adapter body, wherein said plug defines an aperture sized to snugly receive an optical fiber having a predetermined diameter to thereby also create an environmental seal between said plug and said optical fiber such that an overall environmental seal is maintained between the optical fiber and said optical fiber terminus.

Claim 12

The improved terminus assembly of claim 9 wherein said forward end of said adapter body has a reduced diameter relative to other portions of said adapter such that said forward end is sized to generally fit snugly within said rearward end of said optical fiber terminus.

Claim 13

The improved terminus assembly of claim 10 wherein said adapter body further comprises a shoulder adjacent said reduced diameter forward end that is sized to abut against said optical fiber terminus when the forward end of said adapter body is extended into the rearward end of said optical fiber terminus.

Claim 14

The adapter for use with an optical fiber terminus of claim 9 wherein said plug is disposed in said rearward end of said adapter body and at least partially extends into the elongated optical fiber channel of the adapter body such that said plug forms an environmental seal with said adapter body.
