Abstract

A system having a plug and a housing having a hollow space at least partially sealed and an electrical supply line, which is connected to an electrical component, which is separated from the space by a pass-through region, which has a first sealing arrangement that seals in media-tight fashion, the line being surrounded at least partially by the first sealing arrangement, and being contactable in the space, the plug having at least one electrical contact for contacting the line and having at least one second sealing arrangement, which is such that for a contacting, the hollow space is sealed in media-tight, the line of the housing and/or the first sealing arrangement having at least one first locking arrangement, and the electrical contact of the plug having at least one second locking arrangement, the locking arrangements providing that for a contacting, an exclusively irreversible positive and/or non-positive locking is provided.

Claims

1. A system, comprising:

a housing; and

a plug;

wherein the housing has at least one hollow space that is at least partially sealed, at least one electrical supply line connected electrically to at least one electrical component situated in the housing, the component being separated from the hollow space by a pass-through region having at least one first sealing arrangement that seals in media-tight fashion, the electrical supply line being surrounded at least partially by the first sealing arrangement, the electrical supply line being electrically contactable in the hollow space,

wherein the plug has at least one electrical contact for electrically contacting the electrical supply line, and having at least one second sealing arrangement, which is arranged such that when there is an electrical contacting of the electrical supply line with the electrical contact the hollow space is sealed in media-tight fashion, and

wherein at least one of the electrical supply line of the housing and the first sealing arrangement has at least one first locking arrangement, and the electrical contact of the plug having at least one second locking arrangement, the first locking arrangement and the second locking arrangement being configured such that when there is an electrical contacting of the electrical contact with the electrical supply line, an exclusively irreversible positive and/or non-positive locking occurs.

2. The system of claim 1, wherein at least one the housing, the first sealing arrangement, and the second sealing arrangement are each capable of being produced in one piece.

3. The system of claim 1, wherein at least one of the hollow space and the second sealing arrangement have at least one guide arrangement.

4. The system of claim 3, wherein the at least one guide arrangement is configured such that when the housing and the plug are brought together to produce an electrical contacting, the housing and the plug assume a particular position relative to one another, such that in this position, in particular only in this position, at least one of the following is satisfied:

(i) the electrical supply line and the electrical contact are electrically contactable, and (ii) the first locking arrangement and the second locking arrangement are lockable.

5. The system of claim 1, wherein the component is a micromechanical component.

6. The system of claim 1, wherein the locking is a snap connection, and the first locking arrangement is a first snap arrangement, and the second locking arrangement is a second snap arrangement.

7. The system of claim 1, wherein at least one of the electrical supply line of the housing and the electrical contact of the plug have few poles.

8. The system of claim 1, wherein at least one of the electrical supply line and the electrical contact are configured as crimp connectors.

11. The system of claim 1, wherein the housing is a sensor housing.

12. The system of claim 1, wherein media tight includes liquid tight.

13. The system of claim 1, wherein at least one the housing, the first sealing arrangement, and the second sealing arrangement are each capable of being produced in one piece, by at least one of an injection-molding and an extrusion process, as extrusion-coated parts.

14. The system of claim 1, wherein at least one of the hollow space and the second sealing arrangement have at least one guide arrangement, which includes a centering arrangement.

15. The system of claim 1, wherein the component is a micromechanical component.

16. The system of claim 1, wherein the locking is a snap connection, and the first locking arrangement is a first snap arrangement, including a snap-in opening, and the second locking arrangement is a second snap arrangement, including a snap nose.

9. A method for producing a system, the method comprising:

producing a housing;

providing a first sealing arrangement in a pass-through region;

providing a second sealing arrangement on a plug;

installing the housing at a destination location;

providing that the plug is electrically contacted to the housing, and

providing that an electrical contact is electrically contacted with at least one electrical supply line, so that at least one first locking arrangement and at least one second locking arrangement interact in an exclusively irreversibly locking manner;

wherein the system includes the housing and the plug,

wherein the housing has at least one hollow space that is at least partially sealed, the at least one electrical supply line connected electrically to at least one electrical component situated in the housing, the component being separated from the hollow space by the pass-through region having the at least one first sealing arrangement that seals in media-tight fashion, the electrical supply line being surrounded at least partially by the first sealing arrangement, the electrical supply line being electrically contactable in the hollow space,

wherein the plug has at least one electrical contact for electrically contacting the electrical supply line, and having the at least one second sealing arrangement, which is arranged such that when there is an electrical contacting of the electrical supply line with the electrical contact the hollow space is sealed in media-tight fashion, and

wherein at least one of the electrical supply line of the housing and the first sealing arrangement has the at least one first locking arrangement, and the electrical contact of the plug having the at least one second locking arrangement, the first locking arrangement and the second locking arrangement being configured such that when there is an electrical contacting of the electrical contact with the electrical supply line, an exclusively irreversible positive and/or non-positive locking occurs.

10. The method of claim 9, wherein the method is at least one of performed and monitored in an automated fashion.
