Abstract

A securing device for an electrical arrangement is disclosed. The electrical arrangement has at least one electrical component, which has at least one electrical contact element, and at least one electrical connection element, wherein the contact element of the component is connected to the electrical connection element by means of an electrically conductive adhesive, wherein at least one actuator is arranged between the component and the electrical connection element, and an actuating force that moves the component and the connection element apart from one another can be exerted via said at least one actuator.

First claim

The invention claimed is:

1. A securing device for an arrangement of at least one electrical component having at least one electrical contact element and at least one electrical connection element, said securing device comprising:
an electrically conductive adhesive connecting the electrical contact element with the electrical connection element; and
at least one actuator formed as a pressure spring or including a ring-shaped or helical pressure spring, and arranged between the electrical component and the electrical connection element and in surrounding relationship with the contact element, said at least one actuator exerting an actuating force, which seeks to move the electrical component and the electrical connection element apart.

2. The securing device of claim 1 , wherein the electrical component is an electrical energy storage.

3. The securing device of claim 1 , wherein the electrical contact element is rail-shaped.

4. The securing device of claim 1 , wherein the electrically conductive adhesive is made of an adhesive material which when exceeding an adhesive-specific softening temperature becomes softened, wherein below the softening temperature the adhesive force between the contact element of the component and the connection element exerted by the electrically conductive adhesive is greater or equal to the actuating force exerted via the actuator and above the softening temperature is smaller than the actuating force exerted by the actuator.

5. The securing device of claim 1 , wherein the electrically conductive adhesive is thermally curable, and wherein curing of the electrically conductive adhesive is initiated at a temperature exceeding an adhesive-specific curing temperature.

6. The securing device of claim 5 , wherein the curing temperature lies below the softening temperature.

7. The securing device of claim 1 , wherein the electrically conductive adhesive is made of a thermosetting plastic or includes a thermosetting plastic.

8. The securing device of claim 1 , wherein the pressure spring is made of an eclectically insulating material.

9. The securing device of claim 8 , wherein the pressure spring is made of an elastomer.

10. The securing device of claim 1 , further comprising a housing part filled with an electrically insulating protective gas.

11. An energy storage arrangement, comprising:
at least one electrical component having at least one electrical contact element and at least one electrical connection element; and
a securing device, said securing device comprising an electrically conductive adhesive connecting the electrical contact element with the electrical connection element; and at least one actuator arranged between the electrical component and the electrical connection element and in surrounding relationship with the contact element, said at least one actuator exerting an actuating force for moving the electrical component and the connection element apart.

12. A method for electrically contacting an electrical contact element of an electrical component with an electrical connection element, comprising:
arranging at least one actuator formed as a pressure spring or including a ring-shaped or helical pressure spring between the electrical component and the electrical connection element so that the pressure spring is in surrounding relationship with the electrical contact element;
electrically contacting the electrical contact element with the electrical connection element via an electrically conductive adhesive, wherein the actuator is compressed during the electrical contacting against an actuating force of the actuator which seeks to move the electrical component and the electrical connection element apart.

13. The method of claim 12 , wherein the electrical component is constructed as an electric energy storage.

14. The method of claim 12 , wherein the adhesive is made of an adhesive material, which softens when exceeding an adhesive-specific softening temperature, wherein below the adhesive-specific softening temperature an adhesive force exerted by the electrically conductive adhesive between the electrical contact element and the electrical connection element is greater than or equal to the actuating force exerted by the actuator, and above the softening temperature is smaller than the actuating force exerted by the actuator.

15. The method of claim 12 , wherein the electrically conductive adhesive is thermally curable, and wherein curing of the electrically conductive adhesive is initiated when exceeding an adhesive-specific curing temperature.

16. The method of claim 14 , wherein the curing temperature is lower than the softening temperature.

17. The method of claim 15 , further comprising
prior to the electrically connecting, applying the electrically conductive adhesive to respective joining surfaces provided on the contact elements and the electrical connection element;
after the electrically contacting, partially curing the electrically conductive adhesive in a first phase so as to effect a mechanical joining or contacting of the contact elements with the electrical connection element so that an adhesive force is created which compensates the actuating force exerted via the actuator; and
in a second phase following the first phase further curing the electrically conductive adhesive, optionally completely.

18. The method of claim 17 , wherein the partial curing is implemented by inputting energy-rich radiation, preferably heat radiation.

19. The method of claim 17 , wherein the further curing is implemented without inputting energy-rich radiation.
