Abstract

The invention provides an electrical connection arrangement comprising an electrical conductor track element having at least one connection portion electrically connected to a connection zone of an electrical component, wherein a wall is provided in a vicinity of said connection portion and said connection zone, such that a basin is formed and a molding mass is distributed in said basin. Thereby, the connection portion and the connection zone are protected from external influences such as humidity and temperature.

Claims

1. An electrical connection arrangement comprising a flexible multi-layer foil-like electrical conductor track element having at least one connection portion electrically connected to a connection zone of an electrical component, wherein walls of a housing of the electrical connection arrangement are provided in the vicinity of said connection portion and said connection zone, said walls being arranged such that they form, along with the electrical component, a basin, said basin being open on one side only, and an originally flowable molding mass is distributed in said basin such that said connection portion of the electrical conductor track element and said connection zone of the electrical component are completely covered by the molding mass without completely covering the entire track element.

2. The electrical connection arrangement of claim 1, wherein said track element is provided with at least one additional electrical component within said basin.

3. The electrical connection arrangement of claim 1, wherein said track element has a bent portion within said basin.

4. The electrical connection arrangement of claim 1 wherein said connection arrangement is arranged within the housing.

5. The electrical connection arrangement according to claim 1 wherein said walls forms part of the housing.

6. The electrical connection arrangement of claim 1 wherein said connection arrangement is arranged within the housing having at least one retaining protrusion extending through a retainer opening of said track element.

7. The electrical connection arrangement of claim 1 wherein said connection arrangement is arranged within the housing having at least one receiving portion for receiving a part of said electrical component.

8. The electrical connection arrangement of claim 1 wherein at least one layer of said track element comprises electrically conductive tracks.

9. The electrical connection arrangement of claim 1 wherein at least one layer is an electrically isolating layer.

10. The electrical connection arrangement of claim 1 wherein said electrical component has a body that forms a part of said basin.
