Abstract

A cover device for a contact section of a printed circuit board for a mechatronics module is proposed. The printed circuit board includes a contact section which has at least one connection hole, for connecting an electrical connection element to the printed circuit board. The cover device is characterized in that the cover device has a voltage protection element and a sealing element for sealing the at least one connection hole. The sealing element has at least one blind hole thereby, for receiving an end section of the electrical connection element.

First claim

The invention claimed is:

1. A cover device for covering a contact section of a printed circuit board of a mechatronics module, wherein the contact section comprises at least one connection hole for connecting an electrical connection element to the printed circuit board, the cover device comprising:
a voltage protection element adjacent a first surface of the printed circuit board and having opposing edge sections each contacting the first surface, the voltage protection element forming a covering space between the opposing edge sections;
a first sealing element disposed in the covering space, the first sealing element sealing the at least one connection hole when the cover device is assembled to the printed circuit board,
wherein the first sealing element comprises at least one blind hole configured to receive an end section of the at least one electrical connection element; and
a connector device adjacent a second surface of the printed circuit board opposite the first surface, the connector device having opposing edge sections each contacting the second surface, wherein each opposing edge section of the connector device is coupled to a respective edge section of the voltage protection element.

2. The cover device according to claim 1 , wherein when the cover device is assembled to the printed circuit board, the first sealing element is disposed between the voltage protection element and the first surface of the printed circuit board.

3. The cover device according to claim 1 , wherein the first sealing element comprises a sealing mat made of an elastomer material, and
wherein the first sealing element is pressed onto the contact section of the printed circuit board when the cover device is assembled to the printed circuit board.

4. The cover device according to claim 1 , further comprising:
a receiving space formed between the opposing edge sections of the connector device; and
a second sealing element disposed in the receiving space and contacting the second surface of the printed circuit board, the second sealing element sealing the at least one connection hole when the cover device is assembled to the printed circuit board,
wherein the second sealing element comprises at least one through hole configured to receive the at least one electrical connection element when the cover device is assembled to the printed circuit board.

5. The cover device according to claim 4 , wherein when the cover device is assembled to the printed circuit board,
the at least one electrical connection element is adjacently disposed on the contact section of the printed circuit board, and
the at least one through hole of the second sealing element and the at least one blind hole of the first sealing element are aligned with the at least one connection hole of the contact section to receive the at least one electrical connection element.

6. A control system for a mechatronics module, the control system comprising:
a printed circuit board comprising a first surface, a second surface opposing the first surface, and at least one connection hole disposed in a contact section of the printed circuit board and extending between the first surface and the second surface;
at least one electrical connection element extending through the at least one connection hole of the printed circuit board; and
a cover device attached to the printed circuit board in a sealing manner, the cover device comprising:
a voltage protection element having opposing edge sections each contacting the first surface of the printed circuit board;
a first sealing element between the voltage protection element and the first surface of the printed circuit board, the first sealing element configured to seal the at least one connection hole, the first sealing element comprising at least one blind hole into which an end section of the at least one electrical connection element is inserted; and
a connector device having opposing edge sections each contacting the second surface of the printed circuit board, wherein each opposing edge section of the connector device is coupled to a respective edge section of the voltage protection element.

7. The control system according to claim 6 , wherein the voltage protection element forms a covering space between the opposing edge sections of the voltage protection element and the first sealing element is disposed in the covering space.

8. The control system according to claim 6 , wherein a covering space is formed between the voltage protection element and the printed circuit board, wherein the covering space at least partially accommodates the first sealing element.

9. The control system according to claim 6 , wherein the first sealing element comprises a sealing mat made of an elastomer material, and
wherein the first sealing element is pressed onto the contact section of the printed circuit board.

10. The control system according to claim 6 , further comprising:
a receiving space formed between the opposing edge sections of the connector device; and
a second sealing element disposed in the receiving space and contacting the second surface of the printed circuit board, wherein the second sealing element seals the at least one connection hole from the second surface, and
wherein the second sealing element comprises at least one through hole into which the electrical connection element is inserted.

11. The control system according to claim 10 , wherein
the at least one electrical connection element is adjacently disposed on the contact section of the printed circuit board,
the second sealing element comprises at least one adjacently disposed through hole into which the at least one electrical connection element is inserted, and
the first sealing element comprises at least one adjacently disposed blind hole into which an end section of the at least one electrical connection element is inserted.

12. The control system according to claim 6 , wherein the voltage protection element is connected in a liquid-tight manner to the printed circuit board.
