Abstract

A plug connector, in particular a high current plug, having a locking device for the play-free axial fixing of the plug connector with respect to a mating plug connector in a closed position coupled to the mating plug connector, wherein the locking device has a retaining element such as a latching clip to engage axially behind a locking projection on the mating plug connector in the closed position, and a mating pressure element which is located opposite the retaining element in such a way that the locking projection can be accommodated between the retaining element and the mating pressure element in the closed position. An actuating device for pressing on retaining element and/or mating pressure element is formed on the locking projection in a fixing position (II).

First claim

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

1. A plug connector assembly comprising a locking device for the play-free axial fixing of the plug connector with respect to a mating plug connector in a closed position coupled to the mating plug connector, wherein the locking device has a retaining element engaging axially behind a locking projection on the mating plug connector in the closed position and a counter-pressure element which is located opposite the retaining element in such a way that the locking projection can be accommodated between the retaining element and the counter-pressure element in the closed position, and an actuating device for pressing the counter-pressure element against the locking projection in a fixing position (II).

2. The plug connector assembly of claim 1 , wherein the retaining element and/or the counter-pressure element can be moved by the actuating device from a release position (I) with a first distance (A 1 ) between the retaining element and the counter-pressure element into the fixing position (II) with a second distance (A 2 ) between the retaining element and the counter-pressure element which is less than the first distance.

3. The plug connector assembly of claim 1 including at least one inner conductor for conducting current, an outer conductor such as a shielding surrounding the inner conductor and a plug connector housing which includes the locking device and which is surrounded in a sleeve-like manner by the actuating device.

4. The plug connector assembly of claim 1 including two locking devices on two opposite sides of the plug connector, the retaining elements and/or counter-pressure elements of which can be moved by the actuating device.

5. The plug connector of claim 1 wherein said retaining element is a latching clip.

6. The plug connector assembly of claim 1 , wherein the counter-pressure element has a flexible part with a pressing surface designed to be pressed against a side of the locking projection facing the plug connector during coupling, and/or that the retaining element is designed as a rigid latching clip and has a pressing surface designed to be pressed against a side of the locking projection which faces away from the plug connector during coupling.

7. The plug connector assembly of claim 6 , wherein the flexible part is pressed by the actuating device from a release position in which it is bent radially outwards into a flatter fixing position.

8. The plug connector assembly of claim 1 , wherein the actuating device has an axially displaceable sleeve part which surrounds a housing of the plug connector, at least in sections or completely.

9. The plug connector assembly of claim 8 , wherein the actuating device can, at least in sections, be displaced beyond the flexible part and thereby press this into the flat fixing position (II) in which it is pre-loaded against the locking projection.

10. The plug connector assembly of claim 1 , wherein the retaining element deflects radially outwards, at least in sections, during the course of coupling with the mating plug connector, and wherein the actuating device can only be moved into the fixing position (II) if the retaining element is not radially deflected.

11. The plug connector assembly of claim 10 , wherein the actuating device has a grip section for radial deflection of the retaining element during movement from the fixing position (II) into the release position ( 1 ) in order to lift this over the locking projection during decoupling.

12. The plug connector of claim 1 , wherein the actuating device is designed to press the retaining element and the counter-pressure element against the locking projection in a fixing position.

13. The plug connector of claim 12 , wherein the retaining element and/or the counter-pressure element has a flexible part such as a bending part which has a first axial dimension in the release position (I) and a second axial dimension in the fixing position (II) which is larger than the first axial dimension.

14. The plug connector of claim 12 , wherein the retaining element and/or the counter-pressure element can be moved by the actuating device from a release position with a first distance (A 1 ) between the retaining element and the counter-pressure element into the fixing position with a second distance (A 2 ) between the retaining element and the counter-pressure element which is less than the first distance.

15. The plug connector of claim 14 , wherein the counter-pressure element has a flexible part with a pressing surface designed to be pressed against a side of the locking projection facing the plug connector during coupling, and/or that the retaining element is designed as a rigid latching clip and has a pressing surface designed to be pressed against a side of the locking projection which faces away from the plug connector during coupling.

16. The plug connector assembly of claim 1 , wherein the retaining element and/or the counter-pressure element has a flexible part which has a first axial dimension in the release position (I) and a second axial dimension in the fixing position (II) which is larger than the first axial dimension.

17. The plug connector of claim 16 , wherein the flexible part projects further, radially outwards, in the release position (I) than in the fixing position (II) and is preferably designed in the form of a leaf spring curving in an arc.

18. The plug connector assembly of claim 6 , wherein the flexible part projects further, radially outwards, in the release position (I) than in the fixing position (II) and is designed in the form of a leaf spring curving in an arc.

19. The plug connector of claim 18 , wherein the flexible part is pressed by the actuating device from a release position in which it is bent radially outwards into a flatter fixing position.

20. The plug connector assembly of claim 1 , wherein the actuating device has an actuating section which can be displaced in an axial direction (X) relative to the locking device and which can be pushed in the direction of the mating plug connector in order to move it into the fixing position (II) and/or can be pushed away from the mating plug connector in order to move it into the release position (I), or vice versa.

21. The plug connector of claim 20 , wherein the actuating device has an axially displaceable sleeve part which surrounds a housing of the plug connector, at least in sections or completely.

22. The plug connector assembly of claim 1 , wherein the actuating device can be fixed releasably in the fixing position (II) by a retaining mechanism.

23. The plug connector of claim 22 , wherein the retaining mechanism includes snap locking tabs.

24. A plugged connection comprising:
a plug connector comprising a locking device for the play-free axial fixing of the plug connector with respect to a mating plug connector in a closed position coupled to the mating plug connector, wherein the locking device has a retaining element engaging axially behind a locking projection on the mating plug connector in the closed position and a counter-pressure element which is located opposite the retaining element in such a way that the locking projection can be accommodated between the retaining element and the counter-pressure element in the closed position, and an actuating device for pressing the counter-pressure element against the locking projection in a fixing position (II); and
a complementary mating plug connector designed to b
