Abstract

An insert device for sealing a conduit, wherein at least one component of the insert device is configured to separate and position at least one wire in the conduit in order to create a space or inner volume for a sealant to be introduced thereinto. The insert device can have a nozzle configured to allow precise injection of the sealant into the inner volume. The insert device can be operated for quick and reliably repeatable sealing of conduits.

First claim

What is claimed is:

1. A device for positioning cables and sealing a conduit, comprising:
a cable-separating component comprising:
a first body comprising:
removable portions arranged around an outer periphery of the first body,
wherein
when the removable portions are removed from the first body, the first body defines a first notch configured to secure a cable; and

a nozzle comprising:
a second body,
wherein the second body defines a tubular channel,

a first end, and
a second end,
wherein the second end is opposite the first end along the second body, wherein the second end is connected to the first body of the cable-separating component such that the tubular channel continues entirely through the first body of the cable-separating component.

2. The device of claim 1 , further comprising:
a second cable-separating component,
wherein the second cable-separating component is connected to the cable-separating component,
wherein the second cable-separating component includes:
a second body,
 wherein the second body is configured with another removable portions, wherein when the another removable portions are removed from the second body, the second body defines a second notch,
 wherein the second notch is configured to secure the cable.

3. The device of claim 2 , further comprising:
at least one strut,
wherein the second cable-separating component is connected to the cable-separating component via the at least one strut.

4. The device of claim 2 , wherein the cable-separating component and the second cable-separating component are made of a different material than the nozzle.

5. The device of claim 2 , wherein the cable-separating component and the second cable-separating component comprise a polymer.

6. The device of claim 2 , wherein the cable-separating component and the second cable-separating component are flexible with a durometer range of about 40 Shore A to about 100 Shore A.

7. The device of claim 1 , wherein the removable portions include multiple knockout portions for each first notch, wherein the multiple knockout portions can be successively removed to progressively enlarge the first notch.

8. The device of claim 1 , wherein the cable-separating component tapers downwards and away from the nozzle.

9. The device of claim 1 , wherein a longitudinal centerline of the nozzle extends substantially parallel to a longitudinal centerline of the device.

10. The device of claim 1 , wherein the nozzle is corrugated.

11. A method of installing a device for separating cables and sealing a conduit, comprising:
placing the device in the conduit;
connecting the cables to a cable-separating component of the device;
moving the device to a desired position within the conduit; and
delivering a sealant to the device, thereby sealing the device to the conduit;
wherein the cable-separating component includes a body, the body being configured with removable portions arranged around an outer periphery of the body.

12. The method of claim 11 ,
the method further comprising:
removing the removable portions from the body to form notches on the body.

13. The method of claim 12 , wherein the connecting the cables to the cable-separating component of the device comprises placing the cables in the notches.

14. The method of claim 11 , wherein the cable-separating component includes:
a body,
wherein the body is configured with notches and removable portions to enlarge the notches; and

wherein the connecting the cables to the cable-separating component of the device comprises placing the cables in the notches.

15. The method of claim 14 , wherein the placing the cables in the notches comprises leaving the removable portions attached to the body.

16. The method of claim 11 , wherein the delivering the sealant to the device comprises delivering the sealant to the device via a nozzle of the device.

17. The method of claim 11 , wherein the delivering the sealant to the device comprises delivering an irritant.

18. The method of claim 11 , wherein the delivering the sealant to the device comprises delivering a foamed polymer.

19. The method of claim 11 , wherein the moving the device to the desired position within the conduit comprises sliding the device longitudinally along the conduit and away from an opening of the conduit.

20. The method of claim 19 , wherein the delivering the sealant to the device is performed after the moving the device to the desired position within the conduit.
