Abstract

What is described is a connection element for fastening a metal part to a printed circuit board, wherein the connection element has a first portion, which is formed as a press-fit pin to be pressed into a bore of the printed circuit board, and a second portion, which is formed as a screw to be screwed into the metal part.

First claim

What is claimed is:

1. A connection element for fastening a metal part to a printed circuit board, comprising:
a first portion formed as a resilient press-fit pin configured to be pressed into a bore of the printed circuit board; and
a second portion formed as a screw configured to be screwed into the metal part.

2. The connection element according to claim 1 , wherein the second portion comprises a self-tapping or self-cutting screw.

3. The connection element according to claim 1 , wherein the second portion has a screw head configured for transferring a torque for establishing or releasing a screw connection to the connection element.

4. The connection element according to claim 1 , wherein the first portion has a widened middle part.

5. The connection element according to claim 1 , wherein the first portion and the second portion have different material compositions.

6. The connection element according to claim 5 , wherein the first portion is made of brass.

7. The connection element according to claim 5 , wherein the second portion is made of steel.

8. The connection element according to claim 5 , wherein the first portion and the second portion are welded to one another.

9. A system for fastening a metal part to a printed circuit board, comprising:
a printed circuit board;
a metal part; and
a connection element having a first portion formed as a resilient press-fit pin configured to be pressed into a bore of the printed circuit board and a second portion formed as a screw configured to be screwed into the metal part.

10. System according to claim 9 , wherein the metal part is made of aluminium.

11. A method of fastening a printed circuit board to a metal part, the method comprising:
providing a metal part and a printed circuit board;
providing a connection element having a resilient press-fit portion and a thread portion;
pressing the press-fit portion into a bore of the printed circuit board; and
screwing the thread portion into the metal part.

12. The method of claim 11 , wherein the step of screwing the thread portion into the metal part comprises self-tapping or self-cutting of the thread into the metal part.
