US 7922215 B2Abstract
A plug connector for fluid conduits. The plug connector including a housing part with a plug socket for the fluid-tight insertion of a tubular plug-in part, a holding element for locking and a fluid seal for sealing the inserted plug-in part. The plug connector being arranged in a plug socket, the housing part being in two parts comprising a base part and an insert plate which is connected to the base part via a snap-action positive fit connection. The base part comprising a receiving part for the holding element, the fluid seal and the insert part, and a joining part for the joining connection of the housing part to a fluid conduit.
This application claims priority to DE 203 19 959.6, filed Dec. 23, 2003 and PCT/EP2004/053588, filed Dec. 17, 2004.
The present invention relates to a plug connector for fluid conduits.
EP 0 733 844 B1 describes a joining device for fluid conduits. In the device described in the aforementioned application, the division of the housing part into two permits simple installation and removal and release of the plug-in part. The insert part comprises a single-piece plastic molded part, with a dirt seal, which is intended to prevent penetration of dust, dirt, moisture (spray water) and the like, being integrally formed as a single piece in the form of encircling sealing lip. For the purpose of being able to release the plug-in part, the insert part has two elastic latching arms which engage in the base part and in latching openings formed there by means of latching extensions. Each latching arm has an actuating section which protrudes outward out of the base part.
According to the present invention, the base part of the fluid conduit designed in two parts including a receiving part for the holding element, the fluid seal and the insert part, and a joining part for the joining connection of the housing part to a fluid conduit. As a result, various embodiments of the joining part in the manner of an adaptor can be provided, the joining part preferably being connectable to the receiving part, which is of consistently identical design. The connecting region between receiving part and joining part is therefore also of consistently identical design. It is preferably a snap-action positive fit connection with a profile which is closed in the circumferential direction. In addition, there is also the possibility as a result of being able to produce the two parts of the base part from different materials. The receiving part preferably consists of plastic while the joining part consists of a metal such as brass.
The invention will be explained more precisely with reference to the preferred exemplary embodiments which are illustrated in the drawing, in which:
In the various figures of the drawing, identical parts are always provided with the same reference numbers. Therefore, every description of a part with reference to a certain figure of the drawing also applies analogously to all other figures of the drawing in which said part with the corresponding reference number can likewise be seen.
In all of the exemplary embodiments, a plug connector 1 comprises a housing part 2 with (at least) one plug socket 4 (see in particular FIGS. 5 to 7) for the axial, fluid-tight insertion of a tubular plug-in part 6 (see in this regard the separate illustration in FIG. 4). In this example, the plug-in part 6 is designed as a section of a connector piece 8 which—as illustrated—may be designed, for example, as an angle connector. On its side opposite the plug-in part 6, the connector piece 8 can have a connecting section 7 which can be formed analogously to the plug connector 1 or the housing part 2 as a plug socket 9 of similar kind. The connector piece 8 is preferably formed from a single-piece molded part of plastic. However, in principle, the plug connector 1 is also suitable for the direct connection of pipelines, with the plug-in part 6 then being formed by one end of the pipeline (not illustrated).
Owing to the described configuration and arrangement of the holding element 14 and of the fluid seal 16, the plug connector 1 according to the invention operates in accordance with the plug-in principle “holding before sealing” because the plug-in part 6, upon insertion, first of all passes into the region of the holding element 14 and only then into the region of the fluid seal 16. As a result, the plug-in part 6 can already be locked against release via the holding element 14 before the connection is sealed via the fluid seal 16. For this reason, a leakage path is formed in such a manner that, in its pre-locking position of the plug-in part 6, which position is locked by the holding element 14 but is not yet sealed via the fluid seal 16, a physically perceptible leakage which is delimited in a defined manner is ensured. This is indicated in FIG. 2 by arrows 36.
