Abstract

The invention relates to a plug-in connection provided with an angle-locking device for connecting tubular pipes and flexible hoses. The aim of said invention is to improve the design of a said type plug-in connection in such a way that it is possible to produce the angular locking device by particularly simple means, thereby avoiding any risk of an accident during operation of the plug-in connection, and to embodied said connection optionally with or without angular locking device without important transformation expenditures. The inventive connection is, therefore characterised in that it comprises a pipe insertable into internal space of a plug-in part which is provided, on the front-surface side thereof in a plugging.

Claims

1. Plug-in connection with angle-position locking for connecting pipe and hose connections, comprising a plug section, to which the pipe and hose connection is connected, wherein a movable guide which operates in the axial direction and secures against rotation in the circumferential direction is arranged between the plug section and the connection piece, the movable guide comprising guide projections which are distributed along the front face of the plug section and operate in the axial direction, wherein the guide projections cooperate with corresponding recesses disposed on the opposite part, with the recesses being formed directly on the exterior periphery of the opposite part as an installation aid for securing the plug-in connection against the effect from an applied torque, and that the installation aid only permits a certain rotation position between the parts to be plugged together, wherein the connection piece to be plugged in the interior space of the plug section includes axially oriented guide openings disposed on the front face in the plug-in direction, as viewed in the plug-in direction, which are open in the axial direction, and several guide projections projecting radially inwardly into the unobstructed plug opening are arranged on the plug section with an axial spacing from the latching connection.

2. Plug-in connection according to claim 1, wherein the guide projections are formed by punching out the bottom material on the plug section, wherein the guide projections are formed from the remaining material.

3. Plug-in connection according to claims 1, wherein the surface at the outer periphery of the plug section is formed as a smooth surface.

4. Plug-in connection according to claims 1, wherein the guide projections on the plug section are arranged so as to at least in partially engage with the guide openings on the connection piece.

5. Plug-in connection according to claims 1, wherein the plug-in connection with the guide projections, which at least partially engage in the guide openings, forms a mechanism that limits angular rotation

6. Plug-in connection according to claims 1, wherein bottom of the plug section to be punched out, which also forms the radially inwardly oriented guide projections, has material removed in the form of a punched contour.

7. Plug-in connection according to claims 1, wherein the guide projections formed from the bottom of the plug section are differently shaped and have different dimensions.

8. Plug-in connection according to claims 1, wherein the guide projections formed from the bottom of the plug section are identically shaped and have identical dimensions.

9. Plug-in connection according to claims 1, wherein the guide openings in the connection piece are formed according to the shape and dimension of the guide projections in the plug section.

10. Plug-in connection according to claims 1, wherein the plug-in connection with identically formed guide projections on the plug section and corresponding identically formed guide openings in the connection piece can be plugged together in an angular position of 45°

, 60°

or 90°

.

11. Plug-in connection according to claims 1, wherein the plug-in connection comprises angle-independent locking.

12. Plug-in connection according to claims 1, wherein the plug-in connection with angle-independent locking includes guide projections which are bent away from the unobstructed width of the plug opening.

13. Plug-in connection according to claims 1, wherein the plug-in connection with angle-independent locking has an arbitrary rotation position.

14. Plug-in connection according to claims 1, wherein the connection piece is truncated in the axial direction around the area at the front end face.

15. Plug-in connection according to claims 1, wherein the truncated connection piece includes a peripheral open guide opening.

16. Plug-in connection according to claims 1, wherein the plug section has a universal configuration which can be employed for rotation-angle-limiting and rotation-angle-independent plug-in connections.

17. Plug-in connection according to claims 1, wherein the guide opening on the connection piece includes a certain play with respect to insertion length and insertion taper.
