Abstract

This relates to a metallic primary-structure element for an aircraft with a recess, a ground connection that is attached in the recess, and connected in an electrically conductive manner to the metallic primary-structure element, and is designed to receive a connector. This further relates to a method for potential equalization in an aircraft, wherein potential equalization between electrical or electronic devices on board the aircraft and the aircraft itself is produced.

First claim

1 . A metallic primary-structure element for an aircraft, comprising:
a recess; a ground connection that is attached to the metallic primary-structure element in the recess, the ground connection couples in an electrically conductive manner to the metallic primary-structure element, and configured to receive a connector.

2 . The metallic primary-structure element of claim 1 ,
wherein the recess is a borehole.

3 . The metallic primary-structure element of claim 1 ,
wherein the ground connection comprises a cylindrical component.

4 . The metallic primary-structure element of claim 3 ,
wherein the ground connection comprises at least one protuberance that projects, perpendicularly to a longitudinal axis of the cylindrical component of the ground connection, from the generated surface of the cylindrical component.

5 . The metallic primary-structure element of claim 1 ,
wherein the ground connection comprises a sleeve that is electro-conductively coupled to the metallic primary-structure element.

6 . The metallic primary-structure element of claim 5 ,
wherein the sleeve is rotationally symmetrical and comprises at least one supporting surface that is connected to the metallic primary-structure element.

7 . The metallic primary-structure element of claim 5 ,
wherein the connection between the rotationally symmetrical sleeve and the metallic primary-structure element is selected from the group comprising a screw connection, a weld connection or a press connection.

8 . The metallic primary-structure element of claim 5 ,
wherein the connection between the rotationally symmetrical sleeve and the cylindrical component of the ground connection is selected from the group comprising a screw connection, a weld connection or a press connection.

9 . The metallic aircraft primary structure comprising a plurality of metallic primary-structure elements of claim 1 .

10 . A method for potential equalization in an aircraft,
comprising the steps of: providing a metallic primary-structure element for an aircraft; affixing a ground connection to a recess of the metallic primary-structure element establishing an electrically conductive connection between the metallic primary-structure element and the ground connection; and receiving a connector via the ground connection.

11 . A metallic primary-structure element for an aircraft, comprising:
a recess; and a ground connection that is coupled to the metallic primary structure in the recess, the ground connection, electrically coupled to the metallic primary-structure element and configured to receive a connector, wherein the ground connection comprises a sleeve that is electro-conductively coupled to the primary-structure element, and wherein the sleeve is rotationally symmetrical and comprises at least one supporting surface that is connected to the metallic primary-structure element.
