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

1. A bonding device of a shielding (3) of electrical cables (5) arranged in the structure of an aircraft in the area (15) made of a carbon fiber-based composite, characterized in that it comprises a metallic plate (9) with a lug (7) where a bonding lead (1) projecting from said shielding (3) is connected, which is 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).

2. A device according to claim 1, characterized in that the metallic plate (9) is made with titanium.

3. A device according to claim 1, characterized in that the metallic plate (9) is made with aluminum and in that it also comprises an insulating sheet (13) located between it and the area (15).

4. A device according to claim 1, characterized in that it includes at least three rivets (11).

5. A device according to claim 1, characterized in that the bonding lead (1) projects from the shielding (3) at an intermediate area thereof.

6. A device according to claim 1, characterized in that the bonding lead (1) projects from the shielding (3) at an intermediate area thereof.

7. A device according to claim 3, characterized in that the bonding lead (1) projects from the shielding (3) at an intermediate area thereof.

8. A device according to claim 4, characterized in that the bonding lead (1) projects from the shielding (3) at an intermediate area thereof.
