Abstract

Shielded bundles or harnesses of electrical conductors are provided with a metal shielding sheath. At least one network of braid elements has this sheath braided directly thereon using filaments of a wear-resistant material, so that the network of braid elements is protected against frictional wear which may be caused by the metal sheath.

Claims

1. An assembly comprising:

a multibranched bundle of electrical conductors;

an electromagnetic shielding system provided on the multibranched bundle and comprising a network of metal sheath elements surrounding said electrical conductors and interconnected with one another to provide an electrical continuity of said electromagnetic shielding system; and

protecting means, comprising a plurality of protective elements, for protecting the multibranched bundle against frictional wear caused by said metal sheath elements;

wherein said metal sheath elements and said protective elements comprise braid elements formed directly on said multibranched bundle, said braid elements of said metal sheath elements comprising wires, and said braid elements of said protective elements comprising filaments of a wear-resistant material.

2. The electrical conductor bundle as claimed in claim 1, wherein said protective braid elements are arranged between said conductors and said metal sheath elements.

3. The electrical conductor bundle as claimed in claim 1, wherein said protective braid elements are arranged on the external surface of said metal sheath elements.

4. The electrical conductor bundle as claimed in claim 1, wherein said filaments are made of a synthetic material.

5. The electrical conductor bundle as claimed in claim 4, wherein said synthetic material is heat-fusible.

6. The electrical conductor bundle as claimed in claim 1, wherein said filaments are in the form of a yarn.

7. The electrical conductor bundle as claimed in claim 1, wherein said filaments are in the form of a roving.

8. The electrical conductor bundle as claimed in claim 1, that includes a sealing coating covering said protective braid elements and bonded to the latter.
