    The invention relates to a method for connecting a connecting portion of a hose for liquid or gaseous media with a connector, and the connector and a connector assembly with the hose and the connector.
    From AT 509 196 B1 a method for connecting an end portion of a conduit for liquid or gaseous media with a connector is known. The line for liquid or gaseous media here is a soft elastic plastic tube. In the connection method, a first wall portion of the connector is deformed with deformation of the lying between the first and a second wall portion of the connector end portion of the conduit with a spinning tool towards the second wall portion. Before deforming and / or deforming the first wall section with at least one distance measuring device, the surface of the line facing the window opening is detected by a window opening arranged in the first or second wall section, and the deformation of the first wall section is carried out as a function of the result of the distance measuring device Detecting the surface of the end portion of the line performed. Both the first and the second wall portion of the connector have a cylindrical wall surface, whereby a Flohlzy-lindrischer annular space is formed in which the line can be accommodated.
    The method described in AT 509 196 B1 for connecting the end portion of a line to the connector or the configuration of the connector has the disadvantage that the current compression or the required degree of compression can only be controlled insufficiently.
    From AT 511 705 B1 and WO 2015/161333 A1 further methods for fixing a connector in an end region of a line are known.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide an apparatus and a method by means of which an improved connection between a hose and a connector can be made.
    This object is achieved by an apparatus and a method according to the claims.
    According to the invention a method for connecting a connecting portion of a hose for liquid or gaseous media is provided with a connector, wherein the connector comprises a connector body, which connector body has an annular space, which by a sleeve-shaped, in cross-section a central longitudinal axis of the connector annularly surrounding the first shell portion and a sleeve-shaped, in cross-section the central longitudinal axis annularly surrounding second jacket portion of the connector is formed. The first skirt portion is surrounded by the second skirt portion and the skirt portions are open to each other at a second end portion, whereby a hose receiving side of the connector body is formed. - In a first process step, the connecting portion of the tube is inserted from the tube receiving side of the connector body forth in the annulus of the connector and positioned; In a second method step, a pressing tool deforms the first jacket portion of the connector body while simultaneously deforming the connecting portion of the hose between the first jacket portion and the second jacket portion toward the second jacket portion, thereby clamping the connecting portion of the hose between the first jacket portion and the second jacket portion.
    The second shell portion has at a front edge of the Schlauchaufnahmesei te a taper, thereby ensuring that the connecting portion of the hose is deformed during the compression process at least in the distance from the leading edge of the annular space free in the direction of the second shell portion before the connecting portion of the hose on the second Jacket section comes to concern.
    An advantage of the method according to the invention is that the taper ensures that the connecting section of the hose is deformed freely in the direction of the second jacket section at least in the area of the annular space that is distanced from the front edge, before the connecting section of the hose comes into contact with the second jacket section , It can thereby be achieved that a wall thickness of the hose can be detected during the pressing process. In addition, the position of the surface of the tube can be accurately detected by this measure, so that it can be continuously monitored during the pressing process, when the outer circumferential surface of the tube comes to rest on the inner circumferential surface of the second shell portion. This allows the Verpressqualität between hose and connector body to be monitored and in series production a uniform result of the compression can be achieved. This possibility of monitoring the degree of compression of the hose results only if the hose can be deformed freely during the pressing process, at least in an initial stage of compression in the direction of the second shell portion. This can be ensured by the taper, since hoses with too large outer diameter, which would be on the second shell portion, due to the taper can not be introduced into the annulus and thus excrete as rejects.
    Furthermore, it may be expedient if the position of an outer lateral surface of the second jacket section and the position of a surface of the hose and / or the position of an outer circumferential surface of the first jacket section are detected by means of a distance measuring device at least at two axially spaced measuring points. The advantage here is that the position of the lateral surfaces or the position of the tube can be detected by the distance measuring device before the pressing process and that during the compression process, the current Verpressgrad can be detected, the control of the pressing device, the further forming steps based on the current degree of compaction and the desired Verpressgrades can calculate.
    Furthermore, it can be provided that a distance between these two surfaces is calculated from the position of the outer circumferential surface of the second jacket section and the position of the surface of the hose. The advantage here is that can be determined by calculating the distance of the position of the outer circumferential surface of the second shell portion and the position of the surface of the hose, how far the first shell portion and thus the hose can be deformed before the hose on the second shell portion for Concern comes.
    In addition, it can be provided that, before deformation and / or during deformation of the first jacket section, the surface of the tube facing the window openings is detected by means of a distance measuring device through a first window opening and / or second window opening arranged in the second jacket section and the deformation of the first jacket section is performed depending on the result of the performed with the distance measuring device detection of the surface of the tube. The advantage here is that by this measure the current degree of deformation of the first shell section and / or the hose during the pressing process can be constantly monitored and this information can flow into the control of the pressing device.
    Also advantageous is an embodiment, according to which it can be provided that a profile sensor is used as the distance measuring device, which detects at least the two measuring points, preferably several measuring points on a predetermined longitudinal region during the pressing process. In particular, when using a profile sensor, two or more different spatially spaced detection points can be determined at which the position of the first shell portion and / or the position of the second shell portion and / or the position of the tube can be detected.
    According to a further development, it is possible for a wall thickness of the hose to be calculated on the basis of the information about the current position of the pressing tool and on the basis of the measured values of the position of the surface of the hose facing the window openings, based on the distance measurement device. The advantage here is that the wall thickness of the tube can be accurately determined by this measure, with this no own process step before inserting the connector body is necessary in the pressing device. In particular, the relatively large inaccuracies in the wall thickness of the hose can thereby be determined and taken into account as parameters during the pressing process. As a result, a continuous grouting quality can be achieved with several grouting operations.
    Furthermore, it may be expedient if, before inserting the connecting section of the hose into the annular space of the connector, the first jacket section is detected by means of the distance measuring device. The advantage here is that the position of the first shell section can be detected by these measures.
    In addition, it can be provided that the correct insertion position of the connecting section of the hose in the annular space is detected by means of the distance measuring device. The advantage here is that it can be ensured by this measure that the pressing process is started only when the hose is inserted correctly in the annulus and thus the quality of the compression can be increased.
    According to the invention a connector, in particular for use in a method according to one of the preceding claims is formed. The connector comprises a connector body, which connector body has an annular space for receiving a connecting portion of a hose for liquid or gaseous media, wherein the annular space between a sleeve-shaped, in cross-section a central longitudinal axis of the connector annularly surrounding the first shell portion and a sleeve-shaped, in cross-section the central longitudinal axis annularly surrounding second jacket section of the
    Connector is located, wherein the first shell portion is surrounded by the second shell portion and the shell portions are open at a second end portion to each other, whereby a pipe receiving side of the connector body is formed. The second jacket section has a taper at its front edge of the pipe receiving side.
    An advantage of the inventive design of the connector is that it is ensured by the taper that the connecting portion of the hose during the compression process, at least in the front edge of the spaced area of the annular space can be freely deformed in the direction of the second shell portion before the connecting portion of the hose on the second Jacket section comes to concern.
    According to a particular embodiment, it is possible that an insertion width of the annular space is smaller than a main width of the annular space. The advantage here is that the introduction of hoses, which do not have the required dimensions, can be avoided by this measure.
    According to an advantageous development, it can be provided that the insertion width of the annular space is between 50% and 99%, in particular between 70% and 95%, preferably between 88% and 92% of a main width of the annular space. Especially an insertion width in this size range is ideal for limiting the dimensions of the hose.
    In particular, it may be advantageous if the taper is formed on an axial length of 1 mm to 20 mm, in particular of 2 mm to 15 mm, preferably of 2 mm to 8 mm. A taper, which extends to the specified length, can be made particularly simple and efficient.
    Furthermore, it can be provided that the taper is formed projecting about an overhang of 0.1 mm to 10 mm, in particular from 0.3 mm to 3 mm, preferably from 0.4 mm to 1 mm in relation to an inner diameter of the second jacket section. An embodiment of the connector body having in the proportions described here is particularly well suited to fulfill the advantageous effects.
    In addition, it can be provided that a first window opening and a second window opening are formed in the second jacket section, wherein the first window opening is formed in the region of the taper. The advantage here is that the window openings for detecting the surface of the tube or for detecting the surface of the first shell portion may be provided by means disposed on the pressing machine distance measuring device.
    Also advantageous is an embodiment, according to which it can be provided that three first window openings and three second window openings are formed distributed in the second shell section, wherein the window openings are each arranged at an angle of 120 ° to each other on the circumference of the second shell section. The advantage here is that the roundness or the exact shape of the connector body can be detected by this measure.
    By means of a profile sensor, angles, steps and positions can be detected and tracked. For converting the acquired data into common fieldbus systems, an output module can be provided. Thus, the measurement results are output for evaluation or further processing, optionally via digital or analog modules. The profile information can be obtained, for example, via a laser line projected onto the target surface. The diffusely reflected light is imaged via optics onto a sensor matrix. The sensor calculates profile data from the camera image and directly from this the relevant characteristic values. These characteristic values can then be forwarded directly to a controller via RS422 or in conjunction with the output module. Furthermore, it is also conceivable that the profile sensor outputs switching signals rated directly with tolerances.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    Fig. 1 shows a perspective view of a connector assembly 1, which is shown cut in a quarter section. Furthermore, a mating connector 2 is shown schematically in Fig. 1, which is connectable to the connector assembly 1. The interaction between plug assembly 1 and a mating connector 2 is adequately described in AT 509 196 B1.
    In Fig. 1, the connector assembly 1 is shown in an assembled state. The connector assembly 1 comprises a hose 3, a connector 4 and a received in the connector 4 sealing element 5, which serves for sealing between connector 4 and mating connector 2. Of the
    Connector 4 comprises a connector body 6, which is preferably formed as a one-piece forming part, such as a deep-drawn part, in particular of a stainless steel sheet.
    2 shows a schematic representation of a vehicle 7 with a plug connector assembly 1 according to FIG. 1. As can be seen in FIG. 2, the connector assembly 1 is preferably used in a vehicle 7, in particular in a road-bound motor vehicle with an internal combustion engine. Specifically, the connector assembly 1 is used to connect various components of the fresh air supply to the internal combustion engine. For example, it may be provided that the plug assembly 1 is provided with the corresponding mating connector 2 for connecting two parts in the intake region of a turbocharger 8. Furthermore, it can also be provided that such a plug connection is used in the outgoing from the turbocharger 8 pressure side for connecting two components.
    Fig. 3 shows a cross section of the plug assembly 1 along a central longitudinal axis 9 of the connector 4. To describe the individual components well, they are shown in Fig. 3 in an exploded view.
    As can be clearly seen in FIG. 3, the plug connector 4 comprises a spring element 11 by means of which the plug assembly 1 can be secured in its position relative to the mating plug connector 2 mated with the plug assembly 1. The spring element 11 is constructed so that it can be easily activated and deactivated, so that, if necessary, the plug assembly 1 and the mating connector 2 can be separated from each other or connected to each other.
    As can be seen in FIG. 3, a first jacket section 12 is formed on the connector body 6, which surrounds the central longitudinal axis 9 of the connector 4 in a sleeve shape. In other words, the first casing section 12 is a rotationally symmetrical hollow cylinder.
    The first jacket section 12 has an inner lateral surface 13 and an outer lateral surface 14. The first jacket section 12 is surrounded by a second jacket section 15, which is likewise rotationally symmetrical with respect to the central longitudinal axis 9. The first jacket section 12 is connected to the second jacket section 15 at a first end section 16 by means of a first end wall section 17.
    Like the first jacket section 12, the second jacket section 15 also has an inner jacket surface 18 and an outer jacket face 19.
    The first shell portion 12 is limited by its inner circumferential surface 13 and the outer circumferential surface 14, resulting in a wall thickness 20 of the first shell portion 12 results. The second jacket section 15 is likewise bounded by an inner jacket surface 18 and an outer jacket face 19, resulting in a wall thickness 21 of the second jacket section 15.
    The spacing of the two jacket sections 12, 15 relative to one another results in an annular space 22. The annular space 22 is delimited in particular in the radial direction by the outer jacket surface 14 of the first jacket section 12 and by the inner jacket surface 18 of the second jacket section 15.
    The two jacket portions 12, 15 are open at a second end portion 24 of the connector 4 to each other, resulting in a hose receiving side 25 of the connector body 6 results.
    It can be provided that the first casing section 12 has a bevel 26 which is formed on the tube receiving side 25 of the first casing section 12. Such a chamfer 26 has the advantage that the tube 3 can be easily inserted into the annular space 22.
    Furthermore, it can be provided that, viewed in the direction of the first end section 16 of the connector 4, a seal receptacle 27 adjoins the first jacket section 12, which is likewise formed in the connector body 6. In such a seal receptacle 27, the sealing element 5 can be accommodated. Furthermore, it can be provided that the sealing receptacle 27, a third jacket portion 28 connects, which serves to receive the mating connector 2. The third wall section 28 can be adjoined by the end wall section 17, which connects the third jacket section 28 to the second jacket section 15. As already mentioned, the first jacket section 12 is connected to the second jacket section 15 via the third jacket section 28 and the end wall section 17 as a result of this construction or connection.
    Preferably, the connector body 6 is produced in a deep-drawing process, wherein all wall thicknesses of the shell portions of the connector body 6 are approximately equal.
    As can be seen in the view in FIG. 3, it can also be expedient that the seal receptacle 27 has an end wall 29 which adjoins the first jacket section 12. The end wall 29 can here be bent in particular in the direction of the second jacket section 15, resulting in a receiving trough for the sealing element 5.
    The formation of the end wall 29 further brings with it the advantage that in the course of assembly of the plug assembly 1, the hose 3 can be inserted as far into the annular space 22 until it rests against the end wall 29. Thus, the end wall 29 also serve to facilitate the positioning process of the tube 3. In other words, the end wall 29 serves as an axial positioning stop for an end face 30 of the tube 3.
    An axial extension 32 of the annular space 22 is preferably selected to be so large that the annular space 22 has a sufficient length to accommodate the hose 3, in particular a connecting section 33 formed thereon.
    Furthermore, it can be provided that the first jacket section 12 extends further in the direction of the hose receiving side 25 than the second jacket section 15 and thus projects at a certain distance 34 with respect to the second jacket section 15 in the axial direction.
    As is further apparent from FIG. 3, the hose 3 has an inner circumferential surface 35 and an outer circumferential surface 36. A wall thickness 37 of the tube 3, which results from the inner lateral surface 35 and the outer lateral surface 36, is chosen so large that the tube 3 can withstand the pressure occurring in the tube 3. The wall thickness 37 of the tube 3 can be between 1 mm and 20 mm, in particular between 2 mm and 8 mm, preferably between 3 mm and 5.5 mm.
    The second jacket section 15 of the connector body 6 has a taper 39 on a front edge 38 of the hose receiving side 25. By the taper 39 it is ensured that the connecting portion 33 of the hose 3 during the pressing process, at least in the area of the annular space 22 distant from the leading edge 38, can be deformed freely in the direction of the second jacket portion 15 before the connecting portion 33 of the hose 3 on the second jacket portion 15 Concern comes.
    By the taper 39 results in an insertion 40 of the annular space 22, which is smaller than the main width 23 of the annular space 22. Because the insertion distance 40 of the annular space 22 is limited by the taper 39 which is formed in the second shell portion 15, the insertion be avoided by incorrectly sized hoses in the annulus 22 as far as possible.
    Furthermore, it can be provided that the taper 39 extends on an axial length 41. It is conceivable that the taper 39 has a continuously changing cross-section and is therefore conical. Such a trained taper 39 can be easily manufactured manufacturing technology. Furthermore, it is also conceivable that the taper 39 is arcuate. In yet another variant, it is also conceivable that the taper 39 is formed by a gradation. However, the functionality of the taper 39 is not determined by its shape, but is solely and solely necessary for the taper 39 to be projecting around a projection 42 in relation to an inner diameter 43 of the main area of the second jacket section 15.
    In particular, it is provided that the second jacket portion 15 in the region of the taper 39 has a smaller inner diameter 44 than the inner diameter 43 of the main region.
    An inner diameter 45 of the tube 3 is selected to be approximately as large as an outer diameter 46 of the first shell portion 12. It is advantageous if the two diameters 45, 46 are matched to one another such that the tube 3 is easily pushed onto the first jacket portion 12 can be. In the illustrated embodiment, the inner diameter 45 of the tube 3 is approximately 52mm.
    An outer diameter 47 of the tube 3 is preferably chosen to be smaller than an inner diameter 44 of the second jacket portion 15 in the region of the taper 39. As a result, the hose 3 can be easily inserted into the annular space 22 of the connector body 6 during assembly of the connector assembly 1 become. By the formation according to which the second jacket section 15 in the region of the taper 39 has a smaller inner diameter 44 than the inner diameter 43 of the main region, it is ensured that in the inserted state the hose 3 does not bear against the main region of the second jacket section 15.
    Furthermore, it can be provided that the hose 3 has a greater or smaller wall thickness 37 in the region of its connecting section 33 than in a rear hose section 48.
    4 shows the plug assembly 1 together with a pressing machine 49, which serves to connect the hose 1 to the plug connector 4, in a perspective sectional view, and FIG. 5 shows these components in a conventional sectional view, again with the same reference numerals for the same parts.
    Signs or component names as used in the preceding figures 1 to 3. To avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 3 or reference.
    FIGS. 4 and 5 show a first method step for assembling the plug assembly 1, with the hose 3 not yet being pressed with the plug connector 4.
    Fig. 6 shows the connector assembly 1 together with the pressing machine 49 in a perspective sectional view, in turn, the same reference numerals or component designations are used as in the previous figures 1 to 5 for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 5 or reference.
    FIG. 6 shows a further method step for assembling the plug assembly 1, wherein in this illustration the hose 3 is being pressed with the plug connector 4.
    An assembly of the plug assembly 1 will be described below with reference to a synopsis of the illustrations in Figures 3 to 6.
    The pressing machine 49 comprises a pressing tool 50, by means of which the first casing section 12 of the connector body 6 can be deformed and thus the press connection of the plug assembly 1 can be produced. The pressing tools 50 are arranged displaceably in the radial direction 51 on the pressing machine 49.
    In a first method step for Fierstellung the connector assembly 1, the connector body 6 is pushed onto the pressing tool 50 of the pressing machine 49 and thus prepared for the pressing process. The connector body 6 is in this case pushed onto the pressing tool 50, that the annular space 22 is freely accessible, so that the tube 3 can be inserted into this. At closing, the connecting portion 33 of the tube 3 is inserted into the annular space 22 of the connector body 6 in a second method step.
    To check the correct position of the tube 3, a distance measuring device 52 may be provided, which can detect the presence of the tube 3. In particular, it can be provided that a first window opening 53 and a second window opening 54 are arranged in the second jacket section 15 of the connector body 6, through which the measuring beam of the distance measuring device 52 can penetrate into the annular space 22 and thereby the position of the outer lateral surface 14 of the first Jacket section 12 and the position of the outer circumferential surface 36 of the hose 3 can detect.
    In particular, it can be provided that a first measuring point 55 can be detected through the first window opening 53. Depending on whether a hose 3 is inserted into the annular space 22, the first measuring point 55 can lie on the outer circumferential surface 36 of the hose 3 or on the outer circumferential surface 14 of the first jacket section 12. Furthermore, a second measuring point 55 can be detected by the distance measuring device 52, which can detect the position of the outer lateral surface 19 of the second jacket section 15.
    In addition, it can be provided that the distance measuring device 52 measures through the second window opening 54 into the annular space 22. It can be provided that a third measuring point 57 is detected, wherein at the third measuring point 57 analogous to the first measuring point 55, the position of the tube 3 or the position of the first shell portion 12 can be detected. In particular, it can be provided that the distance measuring device 52 is designed in the form of a profile sensor 58.
    Furthermore, it can be provided that a plurality of measuring points is detected by the distance measuring device 52 in a predetermined longitudinal region 59.
    The correct positioning of the tube 3 can be determined in particular by the third measuring point 57. This can be realized by evaluating in the region of the third measuring point 57 whether the detected distance of the third measuring point 57 lies on the tube 3 or on the first jacket section 12. If the third measuring point 57 on the hose 3, this is an indication that the hose 3 is properly inserted into the connector body 6.
    Furthermore, it is conceivable that the first measuring point 55 and / or the second measuring point 56 and / or the third measuring point 57 is detected even before the insertion of the tube 3, whereby the correct position of the connector body 6 on the pressing tool 50 can be controlled. In particular, it can be achieved that an outer diameter 46 of the first jacket section 12 can be detected.
    After insertion of the tube 3, an outer diameter 47 of the tube 3 can be detected by means of the distance measuring device 52. In addition, an outer diameter 60 of the second shell portion 15 can be detected.
    From the position of the outer circumferential surface 19 of the second shell portion 15 and the position of the outer circumferential surface 36 of the tube 3, a distance 61 can be calculated. The distance 61 corresponds in particular to half the difference in diameter of the outer diameter 60 of the second shell section 15 to the outer diameter 47 of the tube 3. If the wall thickness 21 of the second shell section 15 is subtracted from this distance 61, this results in a free space 62 between the inner shell surface 18 of the second shell section 15 and outer circumferential surface 36 of the tube 3. This space 62 is the distance which the tube 3 must be at least deformed before it comes to rest on the second jacket portion 15.
    In an alternative embodiment, it can also be provided that the tube 3 is inserted into the annular space 22 of the connector body 6 in a first method step and the connector body 6 is pushed onto the pressing tool 50 together with the inserted tube 3 only in the second method step.
    If the connector body 6 is correctly positioned on the connector body 6 and the tube 3 is correctly inserted in the annular space 22 of the connector body 6, then the pressing process for connecting the tube 3 to the connector 4 can be started. In this case, the pressing tools 50 are moved in the radial direction 51 outwardly until they rest against an inner circumferential surface 13 of the first shell portion 12.
    Subsequently, the first casing section 12 is deformed by the pressing tools 50 in the radial direction 51 in the direction of the second casing section 15. In this case, the inner circumferential surface 35 of the tube 3 comes to the outer circumferential surface 14 of the first shell portion 12 for concern, whereby the tube 3 is deformed. In the pressing machine 49, a measuring device is provided, by means of which the position of the pressing tools 50 can be precisely detected at any time. As a result or by knowing the wall thickness 20 of the first jacket section 12, the position of the outer jacket surface 14 of the first jacket section 12 can also be determined precisely at any time during the pressing process.
    Now, if the outer circumferential surface 14 of the first shell portions 12 abuts against the inner circumferential surface 35 of the tube 3, the wall thickness 37 of the tube 3 can be calculated by the deformation of the tube 3 by means of the first measuring point 55, which detects the outer circumferential surface 36 of the tube 3 become. This calculation of the wall thickness 37 of the tube 3 can serve to determine the necessary degree of deformation of the tube 3 for a sufficiently tight compression of the tube 3 in the connector body 6.
    By continuous detection of the first measuring point 55 and / or the third measuring point 57 can also be determined when the outer circumferential surface 36 of the tube 3 comes to rest on the inner circumferential surface 18 of the second shell portion 15.
    Any further deformation of the first shell portion 12 after this time leads to an elastic and / or plastic deformation of the tube 3 and thus to a squeezing of the tube 3. In particular, the tube 3 is deformed until it, as shown in FIG. 6 clearly visible a constriction 63, which serves to support the tube.
    After completion of the pressing operation, the pressing tools 50 can be moved back in the radial direction 51 inwardly to release the pressed connector assembly 1 for removal.
