Description

The invention relates to a connector assembly having a fluid line end, which has a bend, and with at least one plastic connector, which is fastened in the region of the bend at the fluid line end. The invention further relates to a method for mounting such a connector assembly. The invention further relates to a method for producing a plastic connector for such a connector assembly.

From the German patent application DE 10 2014 216 045 A1 a connector for connecting two lines for guiding hydraulic fluid for a hydraulically actuated coupling system is known, wherein the connector has a first connection region for arranging and fixing a first conduit and wherein the connector has a second connection region for arranging and fixing a second conduit, wherein the wherein the first connection region is designed to form a material-locking fixation of the first line and wherein the second connection region is designed to form a positive fixation of the second line, wherein the connector is formed from a plastic, wherein the second connection region is designed and structured to form a crimp connection.

The object of the invention is to simplify the production and / or assembly of connector arrangements, with a fluid line end having a bend, and with at least one plastic connector which is fastened in the region of the bend at the fluid line end.

The object is achieved with a connector assembly having a fluid line end, which has a bend, and at least one plastic connector, which is fastened in the region of the bend at the fluid line end, characterized in that in the region of the bend against rotation connected to the fluid line end plastic connector with an anti-rotation is combined for a fluid component to be mounted or mounted on the fluid line end. The fluid line is preferably a steel line. The fluid line end is advantageously provided with a through hole which is surrounded by a torus. The annular bead on the fluid line end advantageously represents an axial stop for a sealing ring. The sealing ring is, for example, an O-ring. In the region of the bend or curvature, the fluid line end has a curved or curved course. Therefore, the plastic connector, which is attached in the region of the bend at the fluid line end, can also be referred to as an angle connector. The plastic connector is advantageously designed as an injection molded part. In order to simplify the assembly of the plastic connector, the plastic connector is advantageously carried out in two parts. The two parts of the plastic connector are advantageously clipped during assembly to the fluid line end with the bend. By attaching the plastic connector in the region of the bend at the fluid line end, twisting of the plastic connector relative to the fluid line end can be prevented in a simple manner. The fluid component to be mounted at the fluid line end with the bend is, for example, a damper, a Kribbelfilter or a vent valve. By preventing rotation can be achieved in a simple manner that the fluid component can be mounted only in a well-defined position at the fluid line end with the plastic connector. In addition, an undesired twisting of the fluid component relative to the fluid line end with the plastic connector is advantageously prevented by the rotation lock.

A preferred exemplary embodiment of the connector arrangement is characterized in that the plastic connector connected to the fluid line end in the region of the bend has at least one recess in which a projection provided on the fluid component to be mounted engages in order to represent the security against rotation. This achieves in a simple manner that the fluid component can be mounted only in exactly one position on the fluid line end with the plastic connector. Thus, an undesired incorrect installation of the fluid component at the fluid line end with the plastic connector is reliably prevented.

A further preferred exemplary embodiment of the connector arrangement is characterized in that the plastic connector connected to the fluid line end in the region of the bend has a plurality of recesses which are provided on an annular body of the plastic connector. This provides the advantage that the fluid line component or different fluid line components in different positions at the fluid line end can be mounted against rotation with the plastic connector or can. The assembly can be simplified, for example, by the use of a suitable template. Several projections may also be provided on the fluid component, which engage in the recesses on the plastic connector which is connected against rotation with the fluid line end. This allows a particularly stable rotation can be displayed.

Another preferred embodiment of the connector assembly is characterized in that the recesses are evenly distributed over a circumference of the plastic connector connected to the fluid line end in the region of the bend. As a result, different positions can be realized in a simple manner, in which the fluid line component can be mounted against rotation on the plastic connector which is connected against rotation with the fluid line end.

A further preferred embodiment of the connector arrangement is characterized in that the fluid line end is provided with the bend on a fluid conduit made of a metallic material. The metallic material is, for example, a steel material. The bend on the fluid line can be more or less pronounced. The bend must only be so pronounced that twisting of the plastic connector relative to the fluid line end is reliably prevented by the bend. Due to the combination with the anti-twist device, an otherwise required torsion-proof connection between the plastic connector and the fluid line end can be dispensed with.

A further preferred embodiment of the connector assembly is characterized in that the plastic connector is made in two parts and is clipped onto the fluid line end with the bend. This simplifies the assembly of the plastic connector.

Another preferred exemplary embodiment of the connector arrangement is characterized in that the plastic connector connected in the region of the bend in a manner secured against rotation with the fluid line end is designed as a male connector. The fluid component is then advantageously equipped with a complementarily equipped female connector. This makes it possible in a simple manner to produce a fluid-tight plug connection between the fluid line end with the plastic connector and the fluid component.

In a method for mounting a connector assembly described above, the above-mentioned object is alternatively or additionally achieved in that the connector assembly is connected to the plastic connector in the bending resistant to the fluid line end, before the fluid component is connected against rotation with the plastic connector. In this case, advantageously only the bend of the fluid line end is used for the rotationally secure connection between the fluid line end and the plastic connector. Further measures for the twist-proof connection between the plastic connector and the fluid line end with the bend are not required.

In a method for producing a plastic connector for a connector arrangement described above, the above-mentioned object is alternatively or additionally achieved in that the at least one recess is produced in an injection mold with at least one movable tool component at a defined position of the plastic connector. Thus, for example, for a given number of units, a position required for a specific fluid component relative to the fluid line end with the plastic connector can be easily realized in terms of manufacturing technology.

The invention further relates to a plastic connector and / or a fluid component for a previously described connector arrangement. The plastic connector and / or the fluid component are / is separately tradable.
