Abstract

A cable separator spline and a cable containing the cable separator spline in its core. The spline extends longitudinally and has a plurality of spaced longitudinally extending open pockets in which cables, such as twisted pair cables, can be placed and form part of the core. A cross-section of the spline has a major axis and a minor axis with the major axis being longer than the minor axis. At least one and preferably at least two pockets are on the major axis, and at least one and preferably at least two pockets are on the minor axis. The core containing the twisted pair cables in the pockets can of course be shielded and jacketed, just jacketed or any other desired cable construction that would benefit from the use of my elongated separator spline.

Claims

1. A twisted-pair cable separator spline comprising:

a longitudinally extending spline having a plurality of spaced longitudinally extending open pockets,

a cross-section of said spline having a major axis and a minor axis,

at least one pocket being on the major axis, and

at least one pocket being on the minor axis, and

wherein said major axis has a length greater than a length of said minor axis.

2. The spline of claim 1 wherein,

said major axis is substantially perpendicular to said minor axis, and

each of said at least one pockets longitudinally extending substantially parallel to each other.

3. The spline of claim 1 wherein,

said spine has first, second, third, and fourth spaced longitudinally extending open pockets,

a cross-section of said spine having a major axis and a minor axis,

said fist and second pockets having substantially the same cross-sectional area, and said third and fourth pockets having substantially the same cross-sectional area.

4. The spine of claim 1 wherein,

said spline has first, second, third, and fourth spaced longitudinally extending open pockets,

a cross-section of said spline having a major axis and a minor axis,

said first and second pockets having substantially the same cross-sectional area and being opposite each other and on the minor axis, and

said third and fourth pockets having substantially the same cross-sectional area and being opposite each other and on the major axis.

5. The spine of claim 4, wherein,

said first and second pockets have a depth greater than a depth of said third and fourth pockets.

6. A twisted-pair cable separator spline comprising:

a longitudinally extending spline having a plurality of spaced longitudinally extending open pockets,

a cross-section of said spine having a major axis and a minor axis,

at least one pocket being on the major axis,

at least one pocket being on the minor axis,

said major axis has a length greater than a length of said minor axis,

said major axis is substantially perpendicular to said minor axis, and each of said at least one pockets longitudinally extending substantially parallel to each other,

each of said at least one pockets have a cross-sectional area which is 75% or less than a cross-sectional area of a circular envelope of a twisted-pair cable to be placed in said at least one pockets.

7. A twisted-pair cable separator spine comprising:

a longitudinally extending spline having a plurality of spaced longitudinally extending open pockets,

a cross-section of said spline having a major axis and a minor axis,

at least one pocket being on the major axis,

at least one pocket being on the minor axis,

said major axis has a length greater than a length of said minor axis,

said spline has first, second, third, and fourth spaced longitudinally extending open pockets,

a cross-section of said spline having a major axis and a minor axis,

said first and second pockets having substantially the same cross-sectional area,

said third and fourth pockets having substantially the same cross-sectional area

said major axis is substantially perpendicular to said minor axis,

said third and fourth pockets having substantially the same cross-sectional area,

said first, second, third, and fourth pockets longitudinally extending substantially parallel to each other, and

each of said at least one pockets have a cross-sectional area which is 75% or less than a cross-sectional area of a circular envelope of a twisted-pair cable to be placed in said at least one pockets.

8. The spline of claim 7, wherein

said first and second pockets having a depth greater than a depth of said third and fourth pockets, and

each of said at least one pockets have a cross-sectional area of about 25% to 75% the cross-sectional area of the circular envelope of the twisted-pair cable to be placed in said at least one pockets.

9. The spline of claim 7 wherein,

said first and second pockets are opposite each other and on the minor axis, and

said third and fourth pockets are opposite each other and on the major axis.
