Abstract

A connection arrangement of a first component on a second component, in particular for a vehicle, is provided, wherein the components are connected together by at least one screw element and at least one screw which is screwed into the screw element and passes through a first passage opening of the first component. The screw element is designed as an expansion sleeve which is partly received in a second opening of the second component and protrudes into the first component and which is expanded along the axial direction of the sleeve by screwing the screw into the expansion sleeve.

First claim

What is claimed is:

1. A connection arrangement for a vehicle, comprising:
a first component;
a second component on which the first component is arranged;
at least one screw element with an opening and an internal thread arranged in the opening wherein the internal thread extends along the opening of the at least one screw element; and
at least one screw with a shaft and an external thread disposed on the shaft wherein the external thread extends along the shaft of the at least one screw;
wherein the first and second components are connected together by the at least one screw element with the internal thread and the at least one screw with the external thread which is screwed into the internal thread of the screw element and passes through a first passage opening of the first component,
wherein the screw element is an expansion sleeve which is partly received in a second opening of the second component and protrudes into the first component and which is expanded along the axial direction of the sleeve by screwing the screw into the expansion sleeve;
wherein the first and second components are electrical conductors for transmitting electric current;
wherein the screw is formed from an electrically conductive material, which touches the first component and is thereby in electrical contact with the first component.

2. The connection arrangement as claimed in claim 1 , wherein
the second opening is a second passage opening, wherein the expansion sleeve passes through the second passage opening of the second component and protrudes into the first component and is expanded along the axial direction by screwing the screw into the expansion sleeve.

3. The connection arrangement as claimed in claim 1 , wherein
the expansion sleeve has a length (I) which is received in the second opening and in the first component and which extends in the axial direction of the expansion sleeve, which length (I) is at least 1.5 times as large as a clamping length of the screw.

4. The connection arrangement as claimed in claim 3 , wherein
the length (I) is at least 2 times as large as a clamping length of the screw.

5. The connection arrangement as claimed in claim 3 , wherein
the length (I) is at least 2.5 times as large as a clamping length of the screw.

6. The connection arrangement as claimed in claim 1 , wherein
the expansion sleeve has at least one hollow cross section which is bounded by a wall in the radial direction of the expansion sleeve, having at least one passage opening.

7. The connection arrangement as claimed in claim 1 , wherein
the expansion sleeve is formed from an electrically conductive material, which touches the second component and is thereby in electrical contact with the second component.

8. A connection arrangement for a vehicle, comprising:
a first component;
a second component on which the first component is arranged;
at least one screw element with an opening and an internal thread arranged in the opening wherein the internal thread extends along the opening of the at least one screw element; and
at least one screw with a shaft and an external thread disposed on the shaft wherein the external thread extends along the shaft of the at least one screw;
wherein the first and second components are connected together by the at least one screw element with the internal thread and the at least one screw with the external thread which is screwed into the internal thread of the screw element and passes through a first passage opening of the first component,
wherein the screw element is an expansion sleeve which is partly received in a second opening of the second component and protrudes into the first component and which is expanded along the axial direction of the sleeve by screwing the screw into the expansion sleeve;
wherein the first and second components are electrical conductors for transmitting electric current;
wherein the screw and the first component are parts of a first connection apparatus comprising at least one first insulating element formed from an electrically insulating material, which entirely encloses an outer side of the first component facing away from the screw in the radial direction of the screw and situated at least partly between the screw and the first component in the radial direction of the screw.

9. The connection arrangement as claimed in claim 8 , wherein
the first insulating element entirely covers a top side of the screw facing away from the first component in the axial direction of the screw.

10. The connection arrangement as claimed in claim 8 , wherein
the expansion sleeve and the second component are parts of a second connection apparatus comprising at least one second insulating element formed from an electrically insulating material, which entirely encloses an outer side of the second component facing away from the expansion sleeve in the radial direction of the expansion sleeve and situated at least partly between the expansion sleeve and the second component in the radial direction of the expansion sleeve.

11. A connection arrangement for a vehicle, comprising:
a first component;
a second component on which the first component is arranged;
at least one screw element with an opening and an internal thread arranged in the opening wherein the internal thread extends along the opening of the at least one screw element; and
at least one screw with a shaft and an external thread disposed on the shaft wherein the external thread extends along the shaft of the at least one screw;
wherein the first and second components are connected together by the at least one screw element with the internal thread and the at least one screw with the external thread which is screwed into the internal thread of the screw element and passes through a first passage opening of the first component,
wherein the screw element is an expansion sleeve which is partly received in a second opening of the second component and protrudes into the first component and which is expanded along the axial direction of the sleeve by screwing the screw into the expansion sleeve;
wherein the first and second components are electrical conductors for transmitting electric current;
wherein the expansion sleeve and the second component are parts of a second connection apparatus comprising at least one second insulating element formed from an electrically insulating material, which entirely encloses an outer side of the second component facing away from the expansion sleeve in the radial direction of the expansion sleeve and situated at least partly between the expansion sleeve and the second component in the radial direction of the expansion sleeve.
