Variable diameter core termination with variable diameter housing
A variable diameter termination includes an elastomeric tubular housing having a first portion with a first inner diameter, a second portion with a second inner diameter, and a third portion disposed between the first portion and the second portion and with a transition inner diameter. The elastomeric tubular housing is disposed on a tubular core that includes a first portion with a third outer diameter, a second portion with a fourth outer diameter, and a third portion disposed between the first portion and the second portion and with a transition outer diameter. The first portion of the elastomeric tubular housing is disposed over the first portion of the tubular core, the second portion of the elastomeric tubular housing is disposed over the second portion of the tubular core, and the third portion of the elastomeric tubular housing is disposed over the third portion of the tubular core.
1. A device for terminating a cable, the device comprising:
an elastomeric tubular housing, in a relaxed state when the elastomeric tubular housing is not disposed on a tubular core and the cable, comprising a first portion having a first inner diameter, a second portion having a second inner diameter, and a third portion disposed between the first portion and the second portion and having a transition inner diameter that increases from the first inner diameter to the second inner diameter;
the tubular core configured to support the elastomeric tubular housing in a radially expanded state and comprising a first portion having a third outer diameter, a second portion having a fourth outer diameter, and a third portion disposed between the first portion and the second portion and having a transition outer diameter that increases from the third outer diameter to the fourth outer diameter,
wherein the first portion of the elastomeric tubular housing is disposed over the first portion of the tubular core, the second portion of the elastomeric tubular housing is disposed over the second portion of the tubular core, and the third portion of the elastomeric tubular housing is disposed over the third portion of the tubular core such that each of the first portion, the second portion, and the third portion of the elastomeric tubular housing is radially expanded to a substantially same extent.
2. The device of claim 1 , wherein the elastomeric tubular housing comprises one or more pull tabs that extend out from a proximal end of the elastomeric tubular housing in a direction opposite to a distal end of the elastomeric tubular housing.
3. The device of claim 2 , wherein the one or more pull tabs include an aperture configured for gripping the pull tab.
4. The device of claim 1 , wherein the tubular core comprises a helically wound ribbon which is removable by pulling on an end of the helically wound ribbon such that the elastomeric tubular housing collapses about a portion of the cable when the helically wound ribbon is removed.
5. The device of claim 1 , wherein the second inner diameter of the elastomeric tubular housing is larger than the first inner diameter of the elastomeric tubular housing, and wherein the fourth outer diameter of the tubular core is larger than the third outer diameter of the tubular core.
6. The device of claim 1 , wherein, in a relaxed state before the elastomeric tubular housing is disposed over the tubular core, the third outer diameter of the tubular core is larger than the first inner diameter of the elastomeric tubular housing, and wherein the fourth outer diameter of the tubular core is larger than the second inner diameter of the elastomeric tubular housing.
7. The device of claim 1 , wherein in the radially expanded state, the first inner diameter of the first portion of the elastomeric tubular housing substantially matches the third outer diameter of the first portion of the tubular core, the second inner diameter of the second portion of the elastomeric tubular housing substantially matches the fourth outer diameter of the second portion of the tubular core, and the transition inner diameter of the third portion of the elastomeric tubular housing substantially matches the transition outer diameter of the third portion of the tubular core.
8. The device of claim 1 , further comprising a plurality of sheds formed on the first portion of the elastomeric tubular housing to provide additional insulation.
9. The device of claim 8 , wherein each shed of the plurality of sheds extend radially outward and substantially perpendicular to the first portion of the elastomeric tubular housing.
10. The device of claim 8 , wherein the plurality of sheds are formed as multiple sets of sheds, and wherein a distance between adjacent sheds of adjacent sets of sheds is larger than the distance between adjacent sheds within one set of sheds of the multiple sets of sheds.
11. The device of claim 10 , wherein the distance between the adjacent sheds within one set of sheds ranges from 1.5 inches to 2.5 inches.
12. The device of claim 10 , wherein the distance between adjacent sheds of adjacent sets of sheds ranges from 2.5 inches to 4.5 inches.
13. The device of claim 10 , wherein the diameter of each shed of the plurality of sheds ranges from 3 inches to 5 inches.
