Abstract

A sealing element for sealing a housing opening in a housing, wherein the sealing element comprises at least one through-opening for the passage of an electrical cable into the housing. The sealing element is formed of a first subcomponent and a second subcomponent, the first subcomponent and the second subcomponent having a different hardness and the two subcomponents are made of silicone.

First claim

We claim:

1. A sealing element for sealing a housing opening in a housing, wherein the sealing element comprises:
a first subcomponent formed of a first silicone material having a first-hardness; and
a second subcomponent formed of a second silicone material having a second-hardness, the first-hardness being greater than the second-hardness, wherein the first silicone material is cross-linked with the second silicone material at the interface between the first subcomponent and the second subcomponent, thereby bonding the first subcomponent and the second subcomponent to one another, and wherein the sealing element defines a through-opening for passage of an electrical cable into the housing.

2. The sealing element according to claim 1 , wherein the sealing element is elastically deformable.

3. The sealing element according to claim 1 , wherein the through-opening is provided in the first subcomponent.

4. The sealing element according to claim 1 , wherein an outer surface of the second subcomponent defines an undulate profile.

5. The sealing element according to claim 1 , wherein the hardness of the first subcomponent is in a range between 60 and 90 Shore and the hardness of the second subcomponent is in a range between 20 and 50 Shore.

6. The sealing element according to claim 1 , wherein the hardness of the silicone varies along the through-opening.

7. The sealing element according to claim 1 , wherein the first subcomponent has a cylindrical shape, and the second subcomponent at least partially covers a surface of the first subcomponent.

8. The sealing element according to claim 1 , wherein the first subcomponent is constructed of a mesh material and the second subcomponent at least partially covers a surface of the first subcomponent.

9. The sealing element according to claim 1 , wherein the first subcomponent defines another through-opening that has a larger cross-section than the through-opening of the second subcomponent.

10. The sealing element according to claim 1 , wherein the sealing element is constructed in layers, wherein a first layer is formed by the first subcomponent and a second layer is formed by the second subcomponent.

11. The sealing element according to claim 1 , wherein a cross-section of the through-opening varies along a region in which the sealing element surrounds the electrical cable.

12. The sealing element according to claim 1 , wherein a first layer thickness of the first subcomponent is greater than a second layer thickness of the second subcomponent.

13. An electrical cable assembly, comprising:
an electrical cable with a contact element attached to one end of the electrical cable;
a housing having a housing opening; and
a sealing element according to claim 1 which sealingly surrounds the electrical cable in the housing opening.

14. The sealing element according to claim 1 , wherein the through-opening is provided in the second subcomponent.
