Abstract

The present invention concerns a module (1) of a seal or transition for cables or wires, which module (1) is to be placed inside a frame (10) together with one or more compression units (12). The module (1) comprises two module halves (2). Each module half comprises an outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The outer part has a straight section (3′) and two end sections (3″) at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view. An inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) is placed in a recess (4) formed between the end sections of the outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) has a number of layers (6).

First claim

The invention claimed is:

1. A module of a seal or transition for cables or wires, which module is to be placed inside a frame together with one or more compression units, and which module comprises two module halves, wherein each module half comprises an outer part and an inner part, wherein the outer part has a straight section and two end sections at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view, wherein the inner part is placed in a recess formed between the end sections of the outer part and wherein the inner part has a number of layers, wherein the layers of the inner part include cuts between the layers of the inner part, wherein the cuts stop short of an outer surface of the inner part such that the cuts do not extend to any part of the outer surface such that the layers of the inner part are attached to each other by a respective material bridge between each adjoining layer of the layers of the inner part, and wherein the outer surface of one module half faces the outer surface of the other module half, and wherein the inner part is made of a softer material than the outer part.

2. The module of claim 1 , wherein each cut has a straight central section and curved end sections at opposite ends of the straight central section, in order to adapt the module to flat cables of different sizes.

3. The module of claim 1 , wherein the material bridges have a thickness of about 0.5 mm.

4. The module of claim 1 , wherein the layers have a thickness of at least 1.5 mm.

5. The module of claim 1 , wherein the inner part is made of a rubber having a hardness of 60±5 Shore A and the outer part is made of a rubber having a hardness of 85±5 Shore A.

6. A module of a seal or transition for cables or wires, which module is to be placed inside a frame together with one or more compression units, and which module comprises two module halves, wherein each module half comprises an outer part and an inner part, wherein the outer part has a straight section and two end sections at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view, wherein the inner part is placed in a recess formed between the end sections of the outer part and protrudes a distance above the outer part, wherein the inner part has a number of layers, wherein the layers of the inner part include cuts between the layers of the inner part, wherein the cuts stop short of an outer surface of the inner part such that the cuts do not extend to any part of the outer surface such that the layers of the inner part are attached to each other by a respective material bridge between each adjoining layer of the layers of the inner part, wherein the outer surface of one module half faces the outer surface of the other module half, and wherein the inner part is made of a softer material than the outer part.

7. The module of claim 6 , wherein the inner part protrudes about 1 mm above the outer part.

8. The module of claim 6 , wherein the module has a rectangular or quadratic form as seen in end view.

9. The module of claim 6 , wherein the inner part of the module half formed by the number of layers has a circular, elliptic, rectangular or quadratic form as seen in end view.

10. The module of claim 6 , wherein the inner part is attached to the outer part by an adhesive.
