Abstract

Abstract An optical fiber splicer for use in a splice closure assembly has a base potion with vertical side walls and first and second ends. A plurality of fiber separating fingers are located at the first end with the fingers extending across the width of the base as defined by the side walls. The fingers can be arrayed as a plurality of longitudinally extending tubes, or in a comb-like structure. A core tube insert member has a first portion adapted to be locked to the base portion, and a tube insert portion extends therefrom. A cap member has latch means thereon for latching to the base portion. The entire splitter is preferably made of a clear acrylic plastic material.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 139 words
An optical fiber splitter for organizing and segregating optical fibers and directing them to a splicing region, said splitter comprising: a base member having first and second ends and first and second spaced side walls; a first set of a plurality of spaced fiber separating finger members at said first end and arrayed across the width of said base member between said side walls; an insert member having a substantially U-shaped body portion and a tube insert member extending therefrom: said base member having first and second spaced slob therein; said body portion having first and second ribs adapted to fit within said slots; a cap member having first and second latching members; and means on said base member for receiving and holding said first and second latching members when said cap member is placed atop said base member.
Claim 2
Dependent Claim 139 words
An optical fiber splitter for organizing and segregating optical fibers and directing them to a splicing region, said splitter comprising: a base member having first and second ends and first and second spaced side walls; a first set of a plurality of spaced fiber separating finger members at said first end and arrayed across the width of said base member between said side walls; an insert member having a substantially U-shaped body portion and a tube insert member extending therefrom: said base member having first and second spaced slob therein; said body portion having first and second ribs adapted to fit within said slots; a cap member having first and second latching members; and means on said base member for receiving and holding said first and second latching members when said cap member is placed atop said base member.
Claim 3
Dependent Claim 58 words
An optical fiber splitter as claimed in claim 1 wherein said first set of fingers comprises a first row of spaced fingers extending across the width of said base member and a second row of spaced fingers superposed over said first row; the fingers in said second row being laterally offset from the fingers in said first row.
Claim 4
Dependent Claim 47 words
An optical fiber splitter as claimed in claim 1 and further comprising a second set of a plurality of fiber separating fingers, said second set of fingers having means for affixing said second set to said base member in superposed relationship to said first set of fingers.
Claim 5
Dependent Claim 58 words
An optical fiber splitter as claimed in claim 3 wherein said second set of fingers comprises a first row of spaced fingers extending across the width of said base member and a second row of spaced fingers superposed over said first row, the fingers in said second row being laterally offset from the fingers in said first row.
Claim 6
Dependent Claim 34 words
An optical fiber splitter as claimed in claim 1 wherein each of said fiber separating fingers is in the shape of a hollow, split substantially tubular member adapted to receive a single fiber therein.
Claim 7
Dependent Claim 39 words
An optical fiber splitter as claimed in claim 1 wherein said spaced fiber separating finger members are arrayed in a comb-like structure with the spaces between fingers being adapted to hold a plurality of fibers contained in a ribbon.
Claim 8
Dependent Claim 22 words
An optical fiber splitter as claimed in claim 1 wherein said base member, said insert member, and said cap member are transparent.
Claim 9
Dependent Claim 27 words
An optical fiber splitter as claimed in claim 1 wherein said base member, said insert member and said cap member are made of a transparent acrylic material.
Claim 10
Dependent Claim 231 words
An optical fiber splitter for use with an optical fiber splice closure having one or more optical fiber cables entrant therein, the cable containing a plurality of optical fibers, said splitter comprising: a base member having a longitudinal axis and having first and second ends and spaced side walls lying in a plane parallel to said axis defining a fiber containing region; a first set of a plurality of spaced fiber separating fingers at said first end and extending across said base member between said side walls; means for introducing fibers into said fiber containing region comprising a core tube insert member having a substantially U-shaped body portion and a tube insert member extending therefrom, said tube insert member having a first split tubular section adjacent said U-shaped body portion and a second split tubular section of lesser cross section than said first tubular portion; slot means in each of said side walls of said base member; said U-shaped body portion having ribs thereon adapted to fit within said slot means to mount and hold said core tube insert member to said base member; a cap member having first and second bifurcated latching ears depending therefrom; each of said side walls having recessed portions for receiving said latching ears; and means in said recessed portions for latching to said ears to hold said cap member in place on said base member.
Claim 11
Dependent Claim 231 words
An optical fiber splitter for use with an optical fiber splice closure having one or more optical fiber cables entrant therein, the cable containing a plurality of optical fibers, said splitter comprising: a base member having a longitudinal axis and having first and second ends and spaced side walls lying in a plane parallel to said axis defining a fiber containing region; a first set of a plurality of spaced fiber separating fingers at said first end and extending across said base member between said side walls; means for introducing fibers into said fiber containing region comprising a core tube insert member having a substantially U-shaped body portion and a tube insert member extending therefrom, said tube insert member having a first split tubular section adjacent said U-shaped body portion and a second split tubular section of lesser cross section than said first tubular portion; slot means in each of said side walls of said base member; said U-shaped body portion having ribs thereon adapted to fit within said slot means to mount and hold said core tube insert member to said base member; a cap member having first and second bifurcated latching ears depending therefrom; each of said side walls having recessed portions for receiving said latching ears; and means in said recessed portions for latching to said ears to hold said cap member in place on said base member.
Claim 12
Dependent Claim 73 words
An optical fiber splitter as claimed in claim 9 wherein said first set of fingers comprises a first row of spaced, split, tubular fingers extending parallel to said longitudinal axis between said side walls and a second row of spaced, split, tubular fingers extending parallel to said longitudinal axis and superposed over said first row, said tubular fingers in said second row being laterally offset from the tubular fingers in said first row.
Claim 13
Dependent Claim 29 words
An optical fiber splitter as claimed in claim 10 wherein said first row of tubular fingers has six fingers and said second row of tubular fingers has six fingers.
Claim 14
Dependent Claim 42 words
An optical fiber splitter as claimed in claim 9 wherein the fingers of said first set of spaced fiber separating fingers extend normal to said longitudinal axis parallel to the planes of said side walls and are arranged in a comb-like structure.
