To enable the hose or line elements to be attached to the housing in a non-rotatable manner, according to the invention the holding means have, between two hose (16, 18) or line sockets, two half-supports (20, 22), which are each allocated to a hose (16, 18) or line socket, wherein the two half-supports (20, 22) have corresponding connection elements with which they can be fastened to one another in a defined position.

Description

Device for connecting at least two hose or pipe elements to a housing

The invention relates according to the preamble of claim 1, a device for connecting at least two hose or conduit elements to a housing, wherein at least two hose or conduit sockets are provided, each sen at one end with connections for mounting a hose or conduit member are formed and at their other end in each case have a housing connection, and further holding means are provided which hold two adjacent hose or pipe stub at a certain distance to each other.

There is a need to attach paired hoses or lines or more than two co-arranged hoses or lines together to a housing and to lay this further. This can for example in cooling systems be the case in which supply and return lines between a radiator and an aggregate to be cooled must be arranged. The hoses or lines are thereby Übli cherweise provided with hose or pipe sockets, which can be inserted into corresponding terminals of a housing.

It is known to connect adjacent hose or pipe sockets with an H-shaped clamp, so that the two hose or pipe sockets are kept at the desired distance from each other before being inserted into the housing. The H-shaped clamp is then bolted to the housing, so that the two hose or Leitungsstut- zen are secured to the housing. In the same way, three or more hoses or lines can be fixed to the housing.

A disadvantage of the known embodiments that no rotation is provided between the nozzle and the housing. Also, the H-shaped clamp can only ensure the proper distance of the hoses or lines for the insertion process, but not prevent their relative rotation to the housing and relative to each other.

The object of the present invention is to provide a device of the type mentioned above, which prevents rotational movements of the hoses or lines relative to each other or relative to the housing.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject matter of claims 2 to 12.

According to the invention the object is achieved by a device of the type mentioned, in which the holding means between two hose or pipe nozzles have two half-stops, which are each associated with a hose or pipe stub, wherein the two half-supports have corresponding connecting elements with which they are fixed together in a connected position in a defined position.

The device according to the invention has the advantage that two or more hose or conduit can initially be fixed to one another via their half-stops at defined intervals, so that they can then be inserted together into connections provided on the housing. The two half-stops of two adjacent hose or conduit have the effect after joining that they on the one hand the distance define the hose or pipe elements and on the other hand prevent twisting of these elements. Even after plugging into the housing, the hose or pipe nozzles can not twist in their connection to the housing. An anti-rotation device between the sockets and the housing can be dispensed with, especially as this would require inserting the sockets into the connection in an exact angular position beforehand. The angular orientation adjusts itself with the device according to the invention without further measures.

Preferably, it is further provided that the connecting elements have corresponding guide elements with which the two connecting elements are inserted into one another after assembly. The guide elements facilitate the coordinated assembly and ensure that the two sockets can be mounted in the desired relative position to each other.

In a still further embodiment of the invention, it is provided that the guide elements of the two connecting elements form a reciprocal linear guide, since this allows a particularly simple manual or automated mating of the half-supports of the connecting pieces. However, it is also possible to use rotary guides, e.g. in the manner of a bayonet.

In a particularly expedient embodiment of the invention, the linear guide is arranged perpendicular to the housing connections of the hose or conduit connection.

All guide elements can have end stops which limit the insertion path and thus define the desired relative position of the connected sockets for mounting on the housing.

A particularly preferred embodiment of the guide elements provides that they are formed by an undercut groove on one and a correspondingly shaped male profile on the other half-support. Corresponding profile shapes can e.g. T-shaped cross sections or so-called dovetail profiles.

In a further particularly preferred embodiment of the invention, it is provided that the two half-stops overlap and each have at least one through-hole, the through-holes in the two half-supports being aligned in the mounted state. The through holes can be used to fix the two sockets in the desired position via their telescoping half-supports before assembly.

The through-hole may also be preferably used to mount the two sockets to the housing, e.g. in that in the through-bore a fastening screw for screwing the retaining means to the housing and securing the two half-support each other is provided in its mounting position.

Depending on the spatial conditions, it may be preferred that the connections for the hose or line elements are aligned at an angle to the housing connections. In particular, with such a design, the security against rotation of the device according to the invention is advantageous, since torques can act on the housing connection due to the angled arrangement after assembly.

Optionally, the two connections of the adjacent hose or pipe elements can also be arranged at an angle to one another after assembly, if this appears expedient for the laying of the hoses or lines.

To form a particularly rotationally secure stop, the two half-stops are formed in a still further preferred embodiment of the invention to the hose or pipe stub.

The hose or pipe stub can easily be made of plastic, wherein the half-supports are then preferably formed in such a way to the neck that the

Hose or pipe stub with the molded half-stops are formed as one-piece plastic injection molded parts.

Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:

FIG. 2 is a view of a first hose nozzle of the device of FIG. 1; FIG.

3 shows a longitudinal section of the first hose nozzle. Fig. 4 is a view of the second hose nozzle of the apparatus of Fig. 1;

Fig. 5 is a longitudinal section of the second hose nozzle.

In Fig. 1 a device 10 is shown, by means of which two hoses (not shown) can be connected to a distributor housing (not shown). The device 10 has two hose sockets 16, 18 to which a respective half support 20, 22 (see also FIGS. 2 to 5) is molded. The two half-stops 20,22 are formed with corresponding guide elements 24,26 that allow mating the two half-stops 20,22 so that they are in a position exactly positioned to each other. The support posts 20,22 form corresponding holding means for fixing the two hose nozzle 16, 18 together in a defined position. On the exact configuration of the guide elements 24,26 will be discussed later in more detail.

The two hose sockets 16,18 each have a connection 28,30 for mounting the hose elements which are formed in the usual way. Furthermore, the two have

Hose sockets 16, 18 each have a housing connection 32, 34 in fluid connection with one of the hose connections 28, 30, which are adapted to the connection openings (not shown) in the housing. In the exemplary embodiment shown, the housing connections 32, 34 are each provided with an O-ring 36, 38 as a seal opposite the connection opening in the housing.

The two half supports 20,22 are each formed with through holes 40,42, which are aligned with each other after the mating of the two half supports 20,22, so that a fastening screw (not shown) can be used, by means of which the device 10 can be screwed against the housing ,

In FIG. 2 is the in FIG. 1 hose connector 18 shown on the left side shown as a single part in a perspective view. In FIG. 3, this hose nozzle 18 is shown in longitudinal section. Good to see is the housing connection 34 with the O-ring 38 for connection to the housing and the hose connection 30, which is designed for connecting a custom-made in the usual way end of a hose designed here as a hydraulic hose. Like the housing connection, the hose connection is only to be understood as an example and can be adapted to the particular hose used, while the housing connection can be adapted to any connection openings in housings used. As shown in FIG. 2 and FIG. 3 is easy to see, the entire hose nozzle 18 is integrally formed, wherein it is made in the embodiment shown as an injection molded part made of plastic. This means that the half-support 22 integral with a tubular body 44 of the

Hose socket 18 is connected. In order to improve the stability of the connection of the half-support 22 to the tubular body 44, the structure of the half-support 22 in the form of ribs 46, 48 is extended around the tubular body 44.

In FIG. 2, the guide elements 26 of the half-support 22, which are embodied here as a linear guide, can be easily recognized, which here have a T-shaped undercut cross-section, so that they form an undercut groove. The undercut guide elements 26 of this half-support 22 serve to cooperate with the guide elements 24 of the half-support 20 of the other hose connector 16, which will be explained in more detail below in connection with FIGS. 4 and 5.

Furthermore, in FIG. 3, the through-bore 42 can be clearly seen, which is provided here with a fitting bushing 50 in order to allow exact positioning to the housing by means of a fitting screw (not shown) when screwing it to the housing.

In Figures 4 and 5, the other hose nozzle 16 is shown in detail, which forms the right part of the device 10 in FIG. The two figures illustrate the conceptual identi rule structure, in turn, a tubular body 45 is integrally formed with the half-support 20, the hose connection 28 and the housing connection 32 as a manufactured by injection molding plastic part. The housing connection 32 is in turn provided with an O-ring 36 for sealing against a correspondingly formed connection opening in the housing. The half-support 20 is in turn formed over ribs 47, 49 on the tubular body 45 in order to improve the stability of the hose nozzle 16.

Deviating from the half-support 22 of the previously discussed Schlauchstut- zen 18 the half-support 20 is formed as a plug-in profile with a T-shaped cross-section which forms the Führungsele- elements 24 which form a linear guide corresponding to the guide elements 26 of the half-support 22. This means that the two half supports 20, 22 can be pushed together in a direction perpendicular to the housing connections 32, 34 as far as a stop which defines the mounting position. In this mounting position, the two housing connections 32, 34 are at a predetermined distance, which corresponds to the spacing of the connection openings in the housing, so that the two half supports 20, 22 connected to the device 10 are inserted directly into the housing Housing can be connected. In the mounting position escape, the through hole 40 of the half support 20 is aligned with the through hole 42 of the half support 22 in alignment, wherein also in the through hole 40, a passport 51 is arranged, which for exact positioning of the half support 20 relative to the housing by inserting a fitting screw provides.

In the hose nozzle 16, the terminal 28 is also angled at an angle to the housing connection 32, wherein it is, however, arranged at a different angle with respect to the half-support 20, so that after the mating of the two hose nozzle 16,18 a non-parallel Position of the two hose nozzle 28,30 gives each other. In principle, however, any desired spatial arrangement of the hose sockets to one another is possible, which is desired for the respective application.

The advantage of the device 10 shown here with the two hose stubs 16, 18 inserted into one another via their half supports 20, 22 and the guide elements 24, 26 provided therein is that the two half supports 20, 22 have the effect of a torque support and prevent them from becoming damaged can twist the connections in the connection openings of the housing. This is achieved without an additional rotation lock between the housing terminals 32,34 and the housing would be required. In addition, the additional element of a previously commonly used H-shaped bracket omitted.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. Thus, as already mentioned, both the housing-side connections and the connections for a hose or line element can be suitably adapted in order to adapt the device to any installation situation in the area of hydraulic or pneumatic systems. In addition to the hose elements shown in the drawings, in particular rigid pipes can also be connected to the housing with the device.

While the embodiment shown, apart from the subordinate mating sleeves 50,51 and sealing rings 36,38 consists of only two components, are of course also Embodiments of several components possible, especially if the sockets 16,18 can not be produced by means of the injection molding process. For example, the support posts 20,22 may be formed as a separate part, which is then each connected in a suitably torsionally rigid with the tubular body 44,45.

The choice of materials is not limited to plastics, but can also extend to metals, for example for high-temperature applications.

A typical application for the device 10 shown is the connection of an oil cooler to a distributor housing, wherein a hose element for the flow to and the other hose element serves for the return of the oil cooler. In the same way, the hoses can be part of a water cycle. If systems with more than two lines or hoses to be arranged in parallel are provided, corresponding further hose or pipe sockets can be connected to the device via half-stops, whereby the middle hose or pipe sockets can then have half-stops on both sides ,

All the features and advantages resulting from the claims, the description and the drawing, including constructive details, spatial arrangements and procedural steps, can be essential to the invention both individually and in the most diverse combinations.
