Abstract

A lead-through for cables, wires or pipes comprising a cylindrical seal and an outer diameter extender. The outer diameter extender is adapted to be mounted on an outer surface of the cylindrical seal. The outer diameter extender comprises two parts, wherein each of the two parts has at least one protruding part and at least one recess. The at least one protruding part of one of the parts of the outer diameter extender is to be received in the at least one recess of the other part of the outer diameter extender.

First claim

The invention claimed is:

1. A lead-through for cables, wire or pipes comprising a cylindrical seal and an outer diameter extender wherein the outer diameter extender is adapted to be mounted on an outer surface of the cylindrical seal, that the outer diameter extender comprises two parts, wherein each of the two parts has at least one protruding part and at least one recess, whereby the at least one protruding part of one of the parts of the outer diameter extender is to be received in the at least one recess of the other part of the outer diameter extender,
wherein the cylindrical seal comprises a cylindrical compressible body, a front fitting, a rear fitting, screws and nuts, wherein the front fitting and the rear fitting are placed on opposite ends of the cylindrical compressible body, wherein the screws goes through openings of the cylindrical compressible body, the front fitting and the rear fitting and wherein the cylindrical compressible body has a central through opening adapted for receiving a cable, wire or pipe.

2. The lead-through of claim 1 , wherein a number of peelable sheets are placed on the inside of the central through opening of the compressible body of the cylindrical seal.

3. The lead-through of claim 1 , wherein the at least one protruding part and the at least one recess of the outer diameter extender are extended in circumferential direction.

4. The lead-through of claim 1 , wherein the outer diameter extender is formed of a number of peelable sheets placed on top of each other.

5. The lead-through of claim 1 , wherein the one or more protruding parts of each part of the outer diameter extender is a tongue.

6. The lead-through of claim 1 , wherein the outer diameter extender is fastened to the seal by means of an adhesive.

7. The lead-through of claim 1 , wherein the outer diameter extender comprises a cylindrical part and a flange at one end of the cylindrical part and that the flange is perpendicular to the cylindrical part and is directed inwards towards a center of the outer diameter extender, wherein the flange has a number of through openings and wherein the flange extends along the circumference of the cylindrical part.

8. The lead-through of claim 7 , wherein a hinge part is arranged on the cylindrical part between the two parts of the outer diameter extender.

9. The lead-through of claim 8 , wherein the hinge part has the form of a weakening extending in axial direction along the entire cylindrical part.

10. The lead-through of claim 8 , wherein the cylindrical part has a through gap opposite the hinge part, by which gap a first axial edge and a second axial edge is formed in the cylindrical part and wherein the at least one protruding part of each part of the outer diameter extender part is a number of fingers extending circumferentially from respective first axial edge and second axial edge of the cylindrical part.

11. The lead-through of claim 10 , wherein the at least one recess of each part of the outer diameter extender is formed by a distance between adjacent fingers, whereby the fingers of one of the parts of the outer diameter extender are received between the fingers of the other part of the outer diameter extender.

12. The lead-through of claim 10 , wherein each part of the outer diameter extender has three fingers extending from the first axial edge and the second axial edge, respectively.

13. The lead-through of claim 10 , wherein the flange ends in level with the second axial edge of the cylindrical part of the outer diameter extender and wherein the flange ends in level with the free outer ends of the fingers of the first axial edge of the outer diameter extender.

14. The lead-through of claim 7 , wherein the flange of the outer diameter extender is adapted to be placed between the front fitting or the rear fitting and the compressible body of the seal at one end of the seal and, wherein at least one screw of the seal is to be received in the openings of the flange.
