Abstract

The invention relates to an electrical bonding device of a shielding ( 3 ) of electrical cables ( 5 ) in aircraft arranged in its structure in an area ( 15 ) made with a carbon fiber-based composite, comprising a metallic plate ( 9 ) with a lug ( 7 ) where a bonding lead ( 1 ) projecting from the shielding ( 3 ) is connected, being fixed to said area ( 15 ) by means of titanium rivets ( 11 ) installed under dry conditions with cadmium steel rings ( 17 ), which are coated with a sealing material ( 19 ).

Claims (9)

1. A bonding device of a shielding of electrical cables arranged in the structure of an aircraft in the area made of a carbon fiber-based composite, wherein the bonding device comprises a metallic plate with a lug where a bonding lead projecting from said shielding is connected, which is fixed to said area by means of titanium rivets installed under dry conditions with cadmium steel rings, which are coated with a sealing material.

2. A device according to claim 1 , wherein the metallic plate is made with titanium.

3. A device according to claim 1 , wherein the metallic plate is made with aluminum and in that it also comprises an insulating sheet located between it and the area.

4. A device according to claim 3 , wherein the bonding lead projects from the shielding at an intermediate area thereof.

5. A device according to claim 1 , which includes at least three rivets.

6. A device according to claim 5 , wherein the bonding lead projects from the shielding at an intermediate area thereof.

7. A device according to claim 1 , wherein the bonding lead projects from the shielding at an intermediate area thereof.

8. A device according to claim 1 , wherein the bonding lead projects from the shielding at an intermediate area thereof.

9. A system for protecting electric cables in an aircraft from electromagnetic fields caused by lightning which comprises shielding surrounding said cables, said shielding being connected by a lead projecting from said shielding to a lug on a metallic plate affixed to an area of aircraft structure formed of carbon fiber-based composite by means of titanium rivets installed under dry conditions with cadmium steel rings which are coated with a sealing material.
