Abstract

A housing for an electric component and a method for producing a housing for an electric component are disclosed. In an embodiment the housing includes a first housing part and a second housing part, wherein the first housing part is connected to the second housing part in a joining region, and wherein the joining region is at least partially covered by a coating containing sprayed-on particles.

Claims

1. A method for producing a housing for an electric component, the method comprising:

providing a first housing part and a second housing part;

joining together the first and second housing parts in at least one joining region; and

spraying particles onto the joining region under atmospheric conditions thereby forming a coating, wherein the joining of the first and second housing parts does not provide a hermetic joining of the first and second housing parts, and wherein gas exchange is initially enabled through the joining region when spraying the particles onto the joining region and is disabled as a layer thickness of the coating is increased.

2. The method according to claim 1,

wherein an adhesive agent is located only at spots between the first housing part and the second housing part such that at least a region in a circumferential joining region between the first housing part and the second housing part is free from the adhesive agent and such that the adhesive agent does not form a contiguous circumferential path along the circumferential joining region.

3. The method according to claim 1, wherein the coating contains a metal.

4. The method according to claim 1, wherein the first housing part comprises an electrically insulating material.

5. The method according to claim 1, wherein an entire upper side of the first housing part is provided with the coating.

6. The method according to claim 1 wherein the housing includes at least one electric contact, and wherein the coating is in electrically conductive connection with the electric contact.

7. The method according to claim 6, wherein the coating electrically connects the electric contact to the first housing part.

8. The method according to claim 1, wherein an adhesive agent electrically connects the first housing part to an electric contact.

9. The method according to claim 1 wherein the first housing part at least partially extends within a recess in the second housing part.

10. The method according to claim 1,

wherein at least one electric component is accommodated in the housing.

11. The method according to claim 1, further comprising:

providing at least one further housing part;

joining the further housing part to the second housing part thereby forming a housing arrangement; and

separating the housing arrangement.

12. The method according to claim 1,

wherein the first housing part, apart from the coating, is secured in places to the second housing part only by a form-locking arrangement of the first and second housing parts.

13. A housing for an electric component comprising:

a first housing part; and

a second housing part,

wherein the first housing part is connected to the second housing part in a joining region,

wherein the joining region is covered by a coating containing sprayed-on particles,

wherein the coating provides a hermetic seal of the housing,

wherein the first housing part, apart from the coating, is secured in place to the second housing part by a form-locking arrangement of the first and second housing pails and/or by an adhesive agent, and

wherein neither the form-locking arrangement nor the adhesive agent provides a hermetic seal of the housing.

14. The housing according to claim 13, wherein the first housing part is formed from an electrically insulating material and comprises protrusions formed from the electrically insulating material, and wherein the protrusions extend into recesses of the second housing part, thereby forming a form-locking arrangement.

15. The housing according to claim 13, wherein the first housing part and the second housing part are not secured to each other by any form-locking arrangement but by and adhesive agent located only at spots between the first housing part and the second housing part.

16. A housing for an electric component comprising:

a first housing part; and

a second housing part,

wherein the first housing part is connected to the second housing part in a joining region,

wherein the joining region is covered by a coating containing sprayed-on particles,

wherein the coating provides a hermetic seal of the housing, and

wherein the first housing part, apart from the coating, is secured in place to the second housing part either by a form-locking arrangement of the first and second housing parts or by an adhesive agent located only at spots between the first housing part and the second housing part, but not by both a form-locking arrangement and an adhesive agent.
