Abstract

An electronic enclosure device including an enclosure, an electric circuit device, and a sealing device is disclosed. The sealing device is provided as one, continuous gasket having a first gasket section configured to seal a first sealing area, a second gasket section configured to seal the second sealing area, and a third gasket section configured to seal the third sealing area.

Claims

1. An electronic enclosure device, comprising:

a enclosure comprising a first enclosure section and a second enclosure section, where a compartment is provided inside the enclosure and where an opening is provided in the enclosure into the compartment;

an electric circuit device comprising a printed circuit board, electronic components connected to the printed circuit board and an electrical connector connected to the printed circuit board, where the electric circuit device is provided in the compartment inside the enclosure and where the electrical connector is provided through the opening of the enclosure; and

a sealing device, wherein;

a first sealing area is provided between a first connection area of the first enclosure section and a first connection area of the second enclosure section,

a second sealing area is provided between a second connection area of the first enclosure section and a first connection area of the electrical connector;

a third sealing area is provided between a second connection area of the second enclosure section and a second connection area of the electrical connector;

where the sealing device comprises one, continuous gasket comprising;

a first gasket section configured to seal the first sealing area;

a second gasket section configured to seal the second sealing area;

a third gasket section configured to seal the third sealing area.

2. The electronic enclosure device according to claim 1, where the first gasket section and the second gasket section provides a continuous first gasket loop and where the third gasket section and the second gasket section provides a continuous second gasket loop.

3. The electronic enclosure device according to claim 1, where the first gasket loop is provided in a first plane and where the second gasket loop is provided in a second plane;

and where the first plane is provided in an angle with respect to the second plane.

4. The electronic enclosure device according to claim 1, where the plane of the first gasket loop is perpendicular to the plane of the second gasket loop.

5. The electronic enclosure device according to claim 1, where the second and third gasket sections form a gasket body comprising at least one opening for the connector.

6. The electronic enclosure device according to claim 1, where the electrical connector is soldered to the printed circuit board.

7. The electronic enclosure device according to claim 1, where the gasket comprises a continuous flange.

8. The electronic enclosure device according to claim 1, where the gasket comprises lamellas.

9. The electronic enclosure device according to claim 1, where the electrical connector is provided as one or more electrical wires connected to the printed circuit board.

10. The electronic enclosure device according to claim 1, where the electrical connector is provided as one or more electrical busbars connected to the printed circuit board.

11. The electronic enclosure device according to claim 1, where the electrical connector is provided with a connection interface on the outside of the enclosure.

12. A method for assembling an electronic enclosure device, comprising:

providing an electric circuit device comprising a printed circuit board, electronic components connected to the printed circuit board and an electrical connector connected to the printed circuit board;

providing an enclosure comprising a first enclosure section and a second enclosure section, where a first sealing area is provided between a first connection area of the first enclosure section and a first connection area of the second enclosure section, where a second sealing area is provided between a second connection area of the first enclosure section and a first connection area of the electrical connector and where a third sealing area is provided between a second connection area of the second enclosure section and a second connection area of the electrical connector;

providing a sealing device comprising one, continuous gasket comprising first, second and third gasket sections;

applying the second and third gasket sections around the electrical connector of the electric circuit device;

inserting the electric circuit device and the gasket into the second enclosure section in one direction, into a position where the second gasket section is sealing the second sealing area; and

applying the first enclosure section in the one direction to the second enclosure section, into a position where the third gasket section is sealing the third sealing area and the first gasket section is sealing the first sealing area.
