Abstract

A plug-type connection with a first plug-type connector and a second plug-type connector, wherein the plug-type connectors each have at least one electrical contact element, which electrical contact elements can be brought into contact with one another by plugging together the first plug-type connector and the second plug-type connector, and the first plug-type connector has a first locking element, with which a second locking element of the second plug-type connector can be latched with tensile and/or shear strength in a locking position of the plug-type connection, wherein the first locking element and/or the second locking element can be shifted by a shifting apparatus in the plug-in direction relative to the contact element of the associated plug-type connector into a contact position of the plug-type connection in order to make contact between the contact elements of the plug-type connectors.

First claim

Thus, having described the invention, what is claimed is:

1. A plug-type connection comprising a first plug-type connector and a second plug-type connector, wherein the first plug-type connector and the second plug-type connector, each possess at least one first electrical contact element, which electrical contact elements can be brought into contact with one another by plugging together the first plug-type connector and the second plug-type connector, such that the first plug-type connector includes a first locking element with which a second locking element of the second plug-type connector can be clipped together in a manner resistant to tensile and compressive forces in a locking position of the plug-type connection by engagement, wherein the first and/or the second locking element can be moved, through a shifting apparatus with one or more threaded spindles rotatable within a through-aperture of the first plug-type connector, in a plugging direction relative to the contact element of the associated plug-type connector, into a first contact position of the plug-type connection in order to make contact between the contact elements of the first plug-type connector and the second plug-type connector.

2. The plug-type connection of claim 1 , wherein the first locking element comprises a projection and the second locking element comprises an elastically deflectable locking tab having a locking aperture which snaps around the projection.

3. The plug-type connection of claim 1 , wherein the shifting apparatus is configured for releasing the clip connection of the first and the second locking elements.

4. The plug-type connection of claim 3 , wherein, starting out from the locking position, the first and/or the second locking element is shiftable into a release position of the plug-type connection in which the clip connection of the first and the second locking elements is released by means of the shifting apparatus.

5. The plug-type connection of claim 4 , wherein the second locking element includes a sloping surface designed such that the shift into the release position leads to a deflection of the locking tab.

6. The plug-type connection of claim 4 , wherein the first and/or the second locking element is loaded in the direction of the locking position through a spring element arranged on the threaded spindle which is pre-biased in the release position.

7. The plug-type connection of claim 1 , wherein the first and the second plug-type connectors, each include at least one second electrical contact element which make contact in the locking position.

8. The plug-type connection of claim 1 , wherein the first and the second plug-type connectors, each includes at least one further electrical contact element which make contact in a second contact position, wherein the second contact position is achieved, starting out from the locking position, by shifting the first and/or the second locking element beyond the first contact position in the plugging direction by means of the shifting apparatus.

9. The plug-type connection of claim 8 , including a securing device comprising a low voltage safety circuit with contact elements which prevents a release of the clip connection of the first and the second locking elements in the first and/or second contact position, wherein the contact elements are always in contact when high voltage contacts of the first and the second plug-type connectors are in contact.

10. The plug-type connection of claim 8 , including a sealing element which, in the first and/or second contact position, is deformed into a gap formed between the first and the second plug-type connectors and which is not deformed in the locking position.

11. The plug-type connection of claim 2 , wherein the shifting apparatus is configured for releasing the clip connection of the first and the second locking elements.

12. The plug-type connection of claim 11 , wherein, starting out from the locking position, the first and/or the second locking element is shiftable into a release position of the plug-type connection in which the clip connection of the first and the second locking elements is released by means of the shifting apparatus.

13. The plug-type connection of claim 4 , wherein the first and the second locking elements include sloping surfaces designed such that the shift into the release position leads to a deflection of the locking tab.

14. The plug-type connection of claim 5 , wherein the first and/or the second locking element is loaded in the direction of the locking position through a spring element arranged on the threaded spindle which is pre-biased in the release position.

15. The plug-type connection of claim 2 , wherein the first and the second plug-type connectors, each includes at least one second electrical contact element which make contact in the locking position.

16. The plug-type connection of claim 12 , wherein the first and the second plug-type connectors, each includes at least one second electrical contact element which make contact in the locking position.

17. The plug-type connection of claim 5 , wherein the first and the second plug-type connectors, each includes at least one further electrical contact element which make contact in a second contact position, wherein the second contact position is achieved, starting out from the locking position, by shifting the first and/or the second locking element beyond the first contact position in the plugging direction by means of the shifting apparatus.

18. The plug-type connection of claim 6 , wherein the first and the second plug-type connectors, each includes at least one further electrical contact element which make contact in a second contact position, wherein the second contact position is achieved, starting out from the locking position, by shifting the first and/or the second locking element beyond the first contact position in the plugging direction by means of the shifting apparatus.

19. The plug-type connection of claim 17 , including a securing device comprising a low voltage safety circuit with contact elements which prevents a release of the clip connection of the first and the second locking elements in the first and/or the second contact position, wherein the contact elements are always in contact when high voltage contacts of the first and the second plug-type connectors are in contact.

20. The plug-type connection of claim 8 , including a sealing element which, in the first and/or the second contact position, is deformed into a gap formed between the first and the second plug-type connectors and which is not deformed in the locking position, wherein the second contact position is achieved from the locking position by shifting the first and/or the second locking element beyond the first contact position, and lies behind the first contact position in relation to the plugging direction.
