Abstract

A construction system for a connection arrangement for media lines, wherein the connection arrangement has a connection body with a receiving opening for a media line and with internal parts for interacting with the media line and providing axial guidance, mechanical locking to prevent detachment, peripheral sealing and, where applicable, internal radial support. Various internal parts can optionally be inserted into the connection body, which is designed to be identical in respect of the internal contour of the receiving opening, and for a particular maximum external line diameter, in order to adapt to at least two dissimilar media lines having different cross-sectional dimensions. The internal parts are adapted, on the one hand, to the permanently identical internal contour of a receiving opening of the connection body and, on the other hand, to the cross-sectional dimension of one of the dissimilar media lines.

First claim

The invention claimed is:

1. A connection device kit for connection with a plurality of different media lines with different cross-section sizes by insertion of a line end of the media line, the connection device kit comprising:
a connection body having a receiving opening defining an inner contour, the connection body having two housing parts including a nozzle housing part and a sleeve housing part, the nozzle housing part and the sleeve housing part being connected to each other via a peripherally closed snap-on connection;
a first plurality of inner parts, the first plurality of inner parts defining an outer contour engageable with the inner contour of the receiving opening and being configured to engage a first range of media lines of different cross-sectional sizes for axial guiding, mechanical locking against release, peripheral sealing and, if appropriate, for inner radial support, wherein the first plurality of inner parts includes a first ring-shaped peripheral seal, a first tiltable retaining ring, and a first insert ring;
a second plurality of inner parts, the second plurality of inner parts defining an outer contour engageable with the inner contour of the receiving opening and being configured to engage a second range of media line of different cross-sectional size for axial guiding, mechanical locking against release, peripheral sealing and, if appropriate, for inner radial support, wherein the second plurality of inner parts includes a second ring-shaped peripheral seal, a second tiltable retaining ring, and a second insert ring;
the first and second peripheral seals each being respectively configured to mount on the inner contour of the receiving opening and defining an inner diameter for engagement with the outer periphery of the media line;
the first and second insert rings respectively supporting the first and second retaining rings and having respective end faces pointing in the insertion direction, the respective end faces each axially delimiting a sealing chamber within the connecting element together with a flank face of the connecting element or of the first housing part lying axially opposite thereto, the peripheral seal being disposed in the sealing chamber;
the first and second retaining rings provided as first and second resiliently elastic toothed rings each including an outer periphery and a plurality of retaining teeth distributed about the periphery, the retaining teeth extending radially and obliquely inwards in a line plug-in direction, the retaining teeth defining an inner diameter that is less than the inner diameter of the peripheral seal and configured for engagement against the media line; and
the first and second insert rings each having a first contact section which has a radially different width corresponding to a respective radial width of the outer periphery of the toothed ring of the respective first and second plurality of inner parts, the first and second insert rings each having a tilting edge for the respective toothed ring whereby the first contact section is axially outwardly adjacent to the tilting edge and perpendicular to the longitudinal axis of the media line, whereby the toothed ring is mounted with its outer periphery having axial movement play within the connection body that is limited by the contact sections of the first and second insert rings and a spaced apart axially opposite contact section defined within one of the nozzle and sleeve housing parts, whereby the outer periphery toothed ring is configured to pivot about the tilting edge out of a starting position in which the outer periphery presses against the first contact section and until the outer periphery contacts the opposite contact section.

2. The connection device kit according to claim 1 , wherein the first plurality and the second plurality of inner parts define in the range of three to six maximal outer line diameters.

3. The connection device kit according to claim 1 , wherein
the retaining teeth are configured for friction and positive locking against the media line, and
the ring-shaped peripheral seal is configured to be mounted to the inner contour of the receiving opening.

4. The connection device kit according to claim 1 , wherein the first and second plurality of inner parts sets further each include a sleeve-shaped release element that is configured to be axially displaceably mounted in the receiving opening of the connecting element, the release element having an end adjacent to the toothed ring and upon axial displacement being configured to engage and elastically deform the toothed ring in the area of the retaining teeth thereby releasing the media line from the connecting device.

5. The connection device kit according to claim 4 , wherein the release elements of the first and second plurality of inner parts have outer contours of the same shape and define different inner diameters adapted to the respective outer line diameters (D), wherein an end of the release elements adjacent to the toothed ring is radially positioned in the area of the retaining teeth in such a way that the retaining teeth can be elastically deformed with axial movement of the release element toward the toothed ring for release of the media line.

6. The connection device kit according to claim 4 , wherein the release elements retainingly engage the connecting element with locking arms, the locking arms being formed by axial slots at an end of the release elements located toward the toothed ring, the locking arms have radially outwardly pointing notches engaged behind a radial stepped surface of the connecting element.

7. The connection device kit according to claim 6 , wherein the locking arms of each of the first and second inner parts sets have identical spring properties and a constant deformation length.

8. The connection device kit according to claim 4 , wherein the release elements of the first and second plurality of inner parts have identical outer peripheral seals configured to sealingly engage the connecting element and further include inner peripheral seals configured to seal a radial annular gap defined in the direction of the media line, wherein the inner peripheral seals have differing inner diameters adapted to the differing outer line diameters (D).

9. The connection device kit according to claim 4 , wherein a ring-shaped closure element is supported by each of the release elements on an outlet side of the connection device for closing an annular opening about an inserted media line, wherein the closure elements have an inner diameter corresponding to the inner diameter of the release element.

10. The connection device kit according to claim 1 , wherein the first and second insert rings each also having an end face defining a limit in the axial direction of a sealing chamber in which the peripheral seal is received, the sealing chamber being also partially defined by the inner contour of the receiving opening.

11. The connection device kit according to claim 10 , wherein the insert rings of the first and second plurality of inner parts have different radial widths corresponding to the respective radial widths of the outer peripheral areas of the respective corresponding toothed rings and are configured with differing lengths for adaptation to the different peripheral seals for a specifically required seal compression in the axial direction to limit the sealing chamber as well as with different radial widths for minimization of a radial gap between the media line and the insert ring in the area of the end face that limits the sealing chamber.

12. The connection device kit according to claim 1 , wherein the first and second plurality of inner parts each include a sup
