Abstract

A cable includes a first conductor and a first conductor isolation, wherein the first conductor includes at least a first break point between the first and second end of the cable and the first conductor isolation includes at least a second break point between the first and second end of the cable, the cable is configured so that the first conductor breaks at the at least first break point if the cable is exposed to a force that is above a first predetermined limit and first conductor isolation breaks at the at least second break point if the cable is exposed to a force that is above a second predetermined limit for avoiding hazardous electric shock after a crash of the vehicle.

First claim

The invention claimed is:

1. A cable for distribution of electric energy within a vehicle, the cable comprising:
a first conductor for distribution of the electric energy between a first end and a second end of the cable;
a first conductor isolation electrically isolating the first conductor;
wherein the first conductor comprising at least a first break point between the first and second ends of the cable comprising a weakening of the first conductor, the at least first break point being configured so that the first conductor breaks at the at least first break point if the cable is exposed to a force that is above a first predetermined limit for cutting the distribution of electric energy at the at least first break point;
the first conductor isolation comprising at least a second break point between the first and second ends of the cable comprising a weakening of the first conductor isolation, the at least second break point being configured so that the first conductor isolation breaks at the at least second break point if the cable is exposed to a force that is above a second predetermined limit for avoiding hazardous electric shock after a crash of the vehicle; and
wherein the at least first break point and the at least second break point are displaced in relation to each other so that the at least first break point and the at least second break point are located at different positions between the first and second ends of the cable for stimulating that the first conductor and the first conductor isolation break at different positions between the first and second ends of the cable.

2. The cable according to claim 1 , the cable further comprising:
a second conductor for distribution of the electric energy between the first and second ends of the cable;
a second conductor isolation electrically isolating the second conductor;
wherein the second conductor comprising at least a third break point between the first and second ends of the cable comprising a weakening of the second conductor, the at least third break point being configured so that the at least second conductor breaks at the at least third break point if the cable is exposed to a force that is above a third predetermined limit for cutting the distribution of electric energy at the at least third break point.

3. The cable according to claim 2 , wherein the second conductor isolation comprising at least a fourth break point between the first and second ends of the cable comprising a weakening of the second conductor isolation, the at least fourth break point being configured so that the at least fourth conductor isolation breaks at the at least fourth break point if the cable is exposed to a force that is above a fourth predetermined limit.

4. A cable for distribution of electric energy within a vehicle, the cable comprising:
a first conductor for distribution of the electric energy between a first end and a second end of the cable;
a first conductor isolation electrically isolating the first conductor;
wherein the first conductor comprising at least a first break point between the first and second ends of the cable comprising a weakening of the first conductor, the at least first break point being configured so that the first conductor breaks at the at least first break point if the cable is exposed to a force that is above a first predetermined limit for cutting the distribution of electric energy at the at least first break point;
the first conductor isolation comprising at least a second break point between the first and second ends of the cable comprising a weakening of the first conductor isolation, the at least second break point being configured so that the first conductor isolation breaks at the at least second break point if the cable is exposed to a force that is above a second predetermined limit for avoiding hazardous electric shock after a crash of the vehicle;
wherein the cable further comprising:
a second conductor for distribution of the electric energy between the first and second ends of the cable;
a second conductor isolation electrically isolating the second conductor;
wherein the second conductor comprising at least a third break point between the first and second ends of the cable comprising a weakening of the second conductor, the at least third break point being configured so that the at least second conductor breaks at the at least third break point if the cable is exposed to a force that is above a third predetermined limit for cutting the distribution of electric energy at the at least third break point;
wherein the second conductor isolation comprising at least a fourth break point between the first and second ends of the cable comprising a weakening of the second conductor isolation, the at least fourth break point being configured so that the at least fourth conductor isolation breaks at the at least fourth break point if the cable is exposed to a force that is above a fourth predetermined limit; and
wherein the at least first break point, the at least second break point, the at least third break point and the at least fourth break point are located at different positions between the first and second ends of the cable for stimulating that the first conductor, the first conductor isolation, the second conductor and the second conductor isolation break at different positions between the first and second ends of the cable.

5. The cable according to claim 2 , wherein the at least first break point and/or the at least third break point is defined by a smaller section surface of the conductor at the least first break point and/or the at least third break point in relation to the section surface of the conductor outside of the at least first break point and/or the at least third break point.

6. The cable according to claim 2 , wherein the at least first break point and/or the at least third break point is defined by a weakening in the material structure of the conductor at the least first break point and/or the at least third break point in relation to the material structure of the conductor outside of the at least first break point and/or the at least third break point.

7. A cable for distribution of electric energy within a vehicle, the cable comprising:
a first conductor for distribution of the electric energy between a first end and a second end of the cable;
a first conductor isolation electrically isolating the first conductor;
wherein the first conductor comprising at least a first break point between the first and second ends of the cable comprising a weakening of the first conductor, the at least first break point being configured so that the first conductor breaks at the at least first break point if the cable is exposed to a force that is above a first predetermined limit for cutting the distribution of electric energy at the at least first break point;
the first conductor isolation comprising at least a second break point between the first and second ends of the cable comprising a weakening of the first conductor isolation, the at least second break point being configured so that the first conductor isolation breaks at the at least second break point if the cable is exposed to a force that is above a second predetermined limit for avoiding hazardous electric shock after a crash of the vehicle;
wherein the cable further comprising:
a second conductor for distribution of the electric energy between the first and second ends of the cable;
a second conductor isolation electrically isolating the second conductor;
wherein the second conductor comprising at least a third break point between the first and second ends of the cable comprising a weakening of the second conductor, the at least third break point being configured so that the at least second conductor breaks at the
