Abstract

A plug connection having: a plug connector with, arranged thereon, a first coding element with a coding pattern and an insertion location with, arranged thereon, a second coding element with a coding pattern that matches the coding pattern, wherein the plug connector can be inserted, in an insertion direction (S), into the insertion location as far as a coupling position, when the first coding element and the second coding element adopt a predefined relative position. The first coding element can be rotated on the plug connector about an axis of rotation (A) that runs parallel to the insertion direction (S), and/or the second coding element is held on the insertion location so as to be able to rotate about the axis of rotation (A).

First claim

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

1. A plug connection, comprising a plug connector with a first coding element arranged thereon with a coding pattern and an insertion location with a second coding element arranged thereon with a coding pattern complementary to said coding pattern, wherein the plug connector can be inserted, in an insertion direction (S), into the insertion location as far as a coupling position, if the first coding element and the second coding element assume a predefined position relative to one another, wherein the first coding element is held on the plug connector so as to be rotatable around an axis of rotation (A) running parallel to the insertion direction (S) and/or the second coding element is held on the insertion location so as to be rotatable around the axis of rotation (A), and having a self-alignment mechanism such that, when plugging in the plug connector, the first coding element and the second coding element are automatically rotated into the predefined position relative to one another, wherein the first coding element is a ring element with two, three or more radially projecting projections, spaced apart from one another at a predefined angle in a circumferential direction, and that the second coding element is a sleeve part with two, three or more guide grooves formed in an inner wall of the sleeve part and spaced apart from one another in a circumferential direction at said predefined angle, and wherein n guide grooves are formed in the sleeve part where n>1, such that the guide grooves, at their front end, cover a circumferential angular range of approximately 360%, the groove walls of adjacent guide grooves being directly adjacent to one another at their front end.

2. The plug connection of claim 1 , wherein a groove width (B) of at least one guide groove is reduced in the insertion direction (S), at least in sections.

3. The plug connection of claim 1 , wherein the at least one of the guide grooves has an entry section with a groove width (B) which narrows in the insertion direction (S) and a guide section following on from the entry section in the insertion direction with substantially constant groove width which is preferably matched to a projection width of at least one associated projection.

4. The plug connection of claim 1 , wherein the plug connector is a high current plug connector connected to a shielded high current cable with an inner conductor contact and an outer conductor surrounding the inner conductor contact, at least in sections, on the outer boundary surface of which the first coding element is arranged.

5. The plug connection of claim 2 , wherein all of the guide grooves has an entry section with a groove width (B) which narrows in the insertion direction (S) and a guide section following on from the entry section in the insertion direction with substantially constant groove width which is preferably matched to a projection width of at least one associated projection.

6. A set of plug connections having a first plug connection and a second plug connection, each plug connection comprising a plug connector with a first coding element arranged thereon with a coding pattern and an insertion location with a second coding element arranged thereon with a coding pattern complementary to said coding pattern, wherein the plug connector can be inserted, in an insertion direction (S), into the insertion location as far as a coupling position, if the first coding element and the second coding element assume a predefined position relative to one another, wherein the first coding element is held on the plug connector so as to be rotatable around an axis of rotation (A) running parallel to the insertion direction (S) and/or the second coding element is held on the insertion location so as to be rotatable around the axis of rotation (A), and having a self-alignment mechanism such that when plugging in the plug connector, the first coding element and the second coding element are automatically rotated into the predefined position relative to one another, wherein the coding pattern of the first and the second plug connection differ from one another, and wherein the complementary coding pattern of the first and second plug connector differ from each other such that the plug connector of the first plug connection can be plugged, as far as the coupling position, into the insertion location of the first plug connection, but not into the insertion location of the second plug connection.

7. The plug connection of claim 6 , wherein the first coding element is a ring element surrounding a main body of the plug connector, and/or the second coding element is a sleeve part held rotatably on the insertion location so as to allow introduction of the ring element, or vice versa.

8. The plug connection of claim 6 , wherein the first coding pattern is in the form of preferably several radially outwardly-projecting projections, and/or the second coding pattern is in the form of preferably several guide grooves, each configured for engagement of a projection, or vice versa.

9. The plug connection of claim 8 , wherein the first coding pattern and the second coding pattern exhibit a multiple radial symmetry.

10. The plug connection of claim 6 , wherein the first coding element is a ring element with two, three or more radially projecting projections, spaced apart from one another at a predefined angle in a circumferential direction, and that the second coding element is a sleeve part with two, three or more guide grooves formed in an inner wall of the sleeve part and spaced apart from one another in a circumferential direction at said predefined angle.

11. The set of plug connections of claim 6 , including three or more plug connections, the plug connectors of which can only be plugged into exactly one associated insertion location.

12. The plug connection of claim 9 , wherein the multiple radial symmetry is 2-fold, 3-fold, or 4-fold.

13. A plug connection, comprising a plug connector with a first coding element arranged thereon with a coding pattern and an insertion location with a second coding element arranged thereon with a coding pattern complementary to said coding pattern, wherein the plug connector can be inserted, in an insertion direction (S), into the insertion location as far as a coupling position, if the first coding element and the second coding element assume a predefined position relative to one another, wherein the first coding element is held on the plug connector so as to be rotatable around an axis of rotation (A) running parallel to the insertion direction (S) and/or the second coding element is held on the insertion location so as to be rotatable around the axis of rotation (A), and having a self-alignment mechanism such that, when plugging in the plug connector, the first coding element and the second coding element are automatically rotated into the predefined position relative to one another, wherein the first coding element is a ring element with two, three or more radially projecting projections, spaced apart from one another at a predefined angle in a circumferential direction, and that the second coding element is a sleeve part with two, three or more guide grooves formed in an inner wall of the sleeve part and spaced apart from one another in a circumferential direction at said predefined angle, wherein a groove width (B) of at least one guide groove is reduced in the insertion direction (S), at least in sections, wherein the at least one of the guide grooves has an entry section with a groove width (B) which narrows in the insertion direction (S) and a guide section following on from the entry section in the inser
