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

What is claimed is:

1. An electrically conductive metallic primary-structure element for an aircraft, comprising:
a recess; and
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 an outer 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. An aircraft primary structure comprising a plurality of metallic primary-structure elements configured in accordance with claim 1 .

9. An electrically conductive 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.

10. A metallic primary-structure element for an aircraft, comprising:
a recess; and
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;
wherein the ground connection comprises a sleeve that is electro-conductively coupled to the metallic primary-structure element; and
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.
