    The invention relates to a method for fixing a connector in an end region of a pipe, in particular a pipe or a hose, the method comprising the following steps: positioning the connector in the end region of the pipe; Positioning a crimping device inside the connector; and fixing the connector in the end portion of the line by performing a crimping operation. During the pressing process, the pressing device is pressed with a predetermined pressing force from the inside against the connector or the line, so that at least a portion of the line and optionally also of the connector deforms and forms a Verpres-sung
    Pressing method for fixing connectors, i. of plugs and sockets or receptacles, in the end portions of lines and the necessary Verpressvorrichtungen are known in principle. To specify the pressing force during a pressing process usually a force-controlled Verpresskraftregelung is used. The required pressing force per article, i. each time for a combination of a particular type of connector and a particular type of line, once fixed.
    Decisive for the quality, in particular for the durability and tightness of the fixation or the compression of the connectors in the end regions of the lines is, above all, that the lines are always pressed to the same degree of compression as possible. The degree of crimping is a relative value (e.g., 50%) and indicates the thickness or residual wall thickness of the conduit in the region of 25-25%
    Pressing after the pressing process with respect to the original thickness or wall thickness of the line shows.
    The disadvantage is that in the previously known compression method due to varying material properties, different dimensions and / or manufacturing tolerances of the plugs or lines of a type and thus the individual structure of the individual connector or the individual line of Verpressgrad the lines at a fixed predetermined pressing force at least slightly varied. In particular, the degree of compression varies in the known pressing method for lines with different wall thicknesses. It is also the case that in the previously known compression method due to the individual condition of the individual connector or the individual line, for example, whether and to what extent lubricant, coolant and / or chips on the surface of the parts or between the parts are available , The degree of compression of the line at a fixed predetermined pressing force thereby also varies at least slightly.
    The present invention is therefore based on the object to provide a method for fixing a connector in an end region of a line, which reaches a possible same degree of compression of the line for a combination of a particular type of connector and a particular type of line at each pressing.
    The object of the invention is achieved by a method of the type mentioned in that for the given pressing force depending on the structure and / or state of the connector and / or the line different values are set so that in each pressing achieved as possible the same Verpressgrad the line becomes.
    In this way, the best possible durability and tightness of the connection between the connector and the line is achieved, which connection is formed by the deformation or compression in at least a portion of the line and optionally in at least a portion of the connector. The necessary constant degree of compression of the lines is not due to changing material properties, different Ab 16:04:40 28-10-2011 7/35 25
    Measurements and the manufacturing tolerances of the plug connectors or lines and / or influenced by changing states of the plug connectors or lines during processing. The reason for this is that such variations are present within one type of connectors or leads, since no attempt is made to eliminate them in advance or exclude them from the outset, but the effects of these variations on the degree of compression and / or or state of the connector currently being processed and / or the line currently being processed differently predetermined pressing force are minimal.
    Advantageous embodiments and developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.
    It is particularly advantageous if, during the processing of a connector and / or a line from a batch other than the one previously present, the predetermined pressing force is adjusted in accordance with the specified degree of pressing.
    In this context, a batch or batch unit is understood to mean the entirety of all units of connectors or lines which have been produced under the same conditions or in a continuous production run. A batch thus changes in particular when there is a change in the manufacturing or manufacturing process, such as a material change, a change of at least one process parameter and / or a change in the production device due to a defect or tool breakage. Within a batch, the structure (material properties, dimensions, manufacturing tolerances, etc.) and / or the state (residues or impurities on the surface, etc.) of the individual connectors or lines are largely the same.
    Thus, the most consistent possible degree of Verpressgrad the lines in particular in a batch change of the connectors and / or the lines sicherge staπt, since experience has shown that the structure and / or the state of the connectors or lines change relatively strongly, especially in a batch change 25 25 8 / 35 16:05:29 28-10-2011 («·« «4« ·· «* Φ Φ • * ·» · · Φ Φ * · · · «φ» ·· Φ * * • I * Φ · · At the same time, the frequency of determining or determining the predetermined pressing force is reduced, which is a good compromise between ensuring a constant as possible Verpressgrads and the effort for the necessary determination and adjustment activities in terms of the pressing force given.
    It is very advantageous if, in the case of a new, not yet processed batch constellation of a connector from a specific batch and a line from a specific batch, the pressing force to be prescribed for the specified degree of pressing is determined in an initial pressing process and stored and used for this batch constellation.
    Under a batch constellation is understood in this context, a combination of a connector from a particular batch and a line from a particular batch. If at least one connector or at least one line from another or new batch is processed, then there is a different or new batch constellation.
    By determining the prescribed for the specified degree of compression Verpresskraft in an initial Verpressvorgang in which the connector is positioned in the end of the line, the most accurate and reliable specification of the correct pressing force is ensured. Likewise, this also takes into account possible changes in the state of the connectors or lines before or during processing in the pressing device, for example by the use of a lubricant in positioning the connector in the end region of the line (joining), for determining the pressing force for the new batch constellation. Furthermore, incorrect Verpressvorgänge due to incorrect information on structure and / or condition of the connectors or lines in the respective batches or to be specified Verpress-forces for the connectors or lines in the respective batches excluded because the respective pressing force on site by the initial Compression process is determined.
    It is also very favorable if, during the processing of a connector and / or a line from a new, not yet processed batch, a separate initial pressing operation is only for 16/16/18 28-10-2011 9/35 -5-parater a connector from the new batch alone and / or only for one line from the new batch is carried out alone. From the results obtained with regard to the Verpress-degree or the force profiles in the connector and / or in the line to be specified for the specified degree of compression Verpresskraft determined and deposited for each batch of connectors and / or lines and used. As a result, the number of initial crimping operations is reduced in comparison with the previously described procedure, in which such an initial crimping process is carried out for each new batch configuration. Subsequently, the material and time associated with the initial grouting operations is reduced. For example, in the case of three plug connector batches and three line batches in the procedure now described, a total of six initial injection operations are necessary and nine batch constellations are possible in the procedure described above and thus nine initial injection operations are necessary.
    It is also advantageous if a minimum value and a maximum value are determined for the given pressing force and a batch of connectors and / or a batch of lines 0 is rejected if the pressing force to be predetermined, which in at least one initial pressing operation for this batch constellation or Batch has been determined to be outside of this range. In this way, defective parts or batches are eliminated before processing in the pressing device. It is advantageous if according to another embodiment of the method in the processing of a connector and / or a line from a new batch or a new batch constellation of a connector from a particular batch and a line from a particular batch to be specified for the specified degree of compression Verpresskraft is determined from a record of the manufacturer or supplier of the connector and / or the line and for the respective batch of connectors and / or lines o-the deposited and used for the respective batch constellation. 16:07:08 28-10-2011 10/35 25 · · · · · ··· «· # ·« · ♦ · · ♦ · · * · « * ···· * • I + * »« «« · »» · · · · · · «··» · * · ♦ «·· * · -6-
    Verpressvorgänge necessary and there is no additional time, material and evaluation costs for such operations. It is favorable if, given a change in the processing process of the injection device, the predetermined pressing force is adjusted according to the specified degree of compression. A change in the processing process is especially possible if a maintenance or renewal of the Verpressvonichtung was made or if an optimization or conversion of the grouting process has occurred The adjustment of the pressing force is carried out according to a stored or newly determined value. In this way, it is ensured that the most consistent degree of compression is ensured even with changes to the Verpressvonichtung, for example in an intervention in the force-controlled Verpresskraft-regulation. It is also favorable if, during a batch change of the connector and / or the line, the previously specified pressing force is adjusted by means of at least one correction value to the now presettable pressing force, so that a deviation in the degree of compression is compensated as well as possible. The stored for each batch of connectors and lines or newly determined, individual Korrektunvert thus allows a very simple adaptation of the previously given pressing force to the now specified Verpresskraft, especially when the batch change for the connector and the line takes place at the same time. In such a case, the two correction values for the pressing force for the now to be processed connector and the now to be processed line are easy to add. In this context, it is also advantageous to specify the correction values for the plug connectors and the lines in each case based on a normal or nominal pressing force.
    It is also advantageous if each connector and / or each line is equipped with a code, on the basis of which a unique batch number of the respective connector or the respective line is determined before the Verprassen and the predetermined pressing force according to the present batch constellation and according to the specified Verpressgrad is adjusted. The adjustment of the pressing force is carried out in accordance with a background 16:07:59 28-10-2011 11/35 25
    or a newly determined value. In this way, the possibilities of incorrect adjustment of the given pressing force are reduced, as represented by the individual marking of the individual connectors or lines, for example, a mixing of connectors or lines from different batches in a container no longer a problem
    It is particularly advantageous if the code containing the batch number is stored in a machine-readable manner, in particular in the form of an optically evaluable, one- or two-dimensional bar code or an electromagnetically interrogatable transponder, since thereby the present batch constellation can be determined automatically to adapt the predetermined pressing force. This allows an increase in the efficiency of the pressing process, as a batch change is automatically detected and the specified pressing force is adjusted accordingly.
    Finally, it is advantageous if the respective given pressing force is predetermined in the form of a certain constant force value or in the form of a force curve over time or over the path. Given a specification in the form of a certain constant force value, a very simple and cost-effective force-controlled pressing force control can be replaced. In the case of a prescription in the form of a course of force over time or over the path, i. When using a force-time control or a force-displacement control for the pressing force, the most optimal results with respect to a uniform or consistent as possible Verpressgrads be achieved.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    1 shows an example of a sectional view of a connector 1 in an end region 2 of a line 3 and a compression device 4 in the implementation of a fixing or pressing process.
    In the illustrated embodiment, the line 3 is designed as a hose, which is preferably made of an elastomer or other plastic or a metal. The hollow cylindrical design of the hose or the line 3 is particularly advantageous with regard to the placement of the end portion 2 of the line 3 with the connector 1 and with regard to the implementation of the pressing process. But there are also lines 3 with elliptical or oval or rectangular cross-sectional boundaries possible.
    The connector 1 is formed in the present embodiment as a receiving device or socket, in soft Aufnahmevorrichfung a plug-in device or a plug can be inserted and there is preferably locked with a detent spring 11. The receiving device or the connector 1 in the present example comprises a Aufnahmehütse 5 made of metal with a two-layered receiving portion 6 for the line 3, a central portion 7 and a tip portion 8, which forms the front end of the receiving sleeve. In the interior 9 of the connector 1, a sealing element 10 made of an elastomer is arranged in the region of the middle section 7 of the receiving sleeve 5. Of course, it is also possible by means of the pressing process to fix the plug-in device or the plug in the end region 2 of the line 3 by means of a pressing operation.
    To apply the force for a pressing operation, the pressing device 4 is equipped with expanding jaws 12, 12 '. The pressing device 4 in the present embodiment comprises eight along a circumference regularly arranged spreading jaws 12,12 *. in FIG. 1, only two of the eight expanding jaws 12, 12 'are shown for reasons of clarity. During a pressing operation, the spreading jaws 12, 12 'of the pressing device 4 are simultaneously and uniformly, preferably by means of a not shown hydraulic 25 16:10:19 28-10-2011 14/35 ·· # »· * 6 ····» · • »*» * * * * * * * »····· * *« · · · * * *
    Drive means, pressed radially outwards, so that their pressing sections 13 cause a compression 14 of the line 3 and optionally also of the connector 1 in its receiving portion 6.
    If, as shown in FIG. 1, an inner layer 15 of the two-layer receiving section 6 of the connector 1 is pressed with the expanding jaws 12, 12 'during a pressing operation, then at least the partial region of the plug-in connector 1 or the inner layer 15 is made of a metal which deformed during this process, so that a stable and durable compression 14 is made. If, according to an embodiment of the method of injection not shown, only the line 3 with the spreading jaws 12, 12 'is deformed, then at least one partial region 16 of the line 3, which partial region 16 is pressed in this process, is made of a metal, so that also in this case the necessary stability and durability of the compression 14 is achieved. An outer layer 17 of the receiving section 6 of the connector 1 is basically not deformed in the pressing process in Fig. 2 are the basic process steps of the pressing process, which is executable with the pressing device of FIG. 1, shown in a flow chart. After the start of the pressing process for fixing the connector 1 in the end region 2 of the line 3, a connector 1 and a line 3 is provided or selected for processing in a method step 23. In a substantial, further process step 18, a Ver-pressing force 19 depending on the structure and / or state of the connector 1 and the line 3 is individually specified or set, so that in each and in particular just performed Verpressvorgang the same Verpress-degree of the line 3 is achieved. The pressing force 19 designates the force with which the expanding jaws 12, 12 'of the pressing device 4 are pressed against the line 3 and, as explained in the present exemplary embodiment, against the inner layer 15 of the receiving section 6 of the connector 1 during a pressing operation, so that a deformation of the line 3 and in this case, the connector 1 is achieved and a tight and permanent connection or compression 14 between the connector 1 and the line 3 is given. 16:11:09 28-10-2011 15/35 25 16:11:09 28-10-2011 15/35 25 * * · * suffered · »·« «» »4 * · * ψβ · · · 1 * fe «B» * · «* > • * * * * * * * * * * -11-
    The determination of the momentarily exerted pressing force 19 (actual pressing force) for the control is possible directly or indirectly. A direct determination can be carried out, for example, by means of at least one force-measuring sensor in the expanding jaws 12, 12 'of the pressing device 4. In an indirect way, the pressing force 19 is determined, for example, via an axial driving force in the pressing device 4, which axial driving force is converted into a radially outwardly directed movement of the expanding jaws 12, 12 '. The determined during this axial drive force must therefore be converted to the actual pressing force 19.
    An advantage of the direct determination of the pressing force 19 is the higher accuracy achievable thereby. In the indirect determination, among other things, there are cost advantages in the manufacture and replacement of the tools or spreading jaws 12, 12 'of the pressing device 4, since this is possible independently of any force measuring sensors.
    In further method steps according to FIG. 2, the plug connector 1 is positioned in the end region 2 of the line 3 and the pressing device 4 in the interior 9 of the plug connector 1. Specifically, in the last described method step, the expanding jaws 12,12 * of the pressing device 4 are positioned inside 9 of the connector 1, wherein this positioning by moving the pressing device 4 and the spreading jaws 12,12 'and / or by moving the connector 1 and the line 3 is achieved. After the successful completion of the positioning of the connector 1 is fixed in the end portion 2 of the line 3 by exporting a Verpressvorgangs, wherein the expanding jaws 12,12 'of the pressing device 4 with the previously defined in step 18, individual pressing force 19 from the inside directly against the connector and is pressed indirectly against the line 3. As a result, at least the portion 16 of the line 3 and in the present embodiment shown in FIG. 1, a portion of the connector 1 is deformed and it forms a compression 14 of the receiving portion 6 of the connector 1 and the line. 3
    If a further sealing operation is to be carried out, a new connector 1 and a new conduit 3 are provided for processing and the further method steps of the previously described compression method are 25 16:12:00 28-10-2011 25 16/35
    -12- performed. If no further pressing process is carried out, the pressing process ends at this point.
    Before carrying out a Verpressvorgargs the line 3 has a wall thickness 20. Due to the deformation due to the pressing process, this wall thickness 20 in the region of the pressing 14 is reduced to a grouting thickness 21. The ratio of the grouting thickness 21 and the wall thickness 20 in percent gives the degree of compression of the pipe 3. This degree of compacting is intended to ensure a high quality of the grouting 14 be as equal as possible to each pressing process.
    It is particularly expedient if the pressing force 19 predetermined in each case in a pressing operation is predetermined in the form of a specific force value or in the form of a force curve over time or over the path.
    FIG. 3 shows a possible embodiment of the method step 18 of the compression method according to FIG. 2 in a flowchart, in which method step 18 the pressing force 19 for the pressing process is predetermined.
    In such an embodiment of the method step 18 as in the other possible embodiments of the method step 18 as shown in FIGS. 4 and 5 is in the processing of a connector 1 from another, not processed in the previous pressing process batch and / or a line 3 from another , Not previously processed batch in the previous pressing the previously specified pressing force 19 adjusted according to the specified Verpressgrad so that in each pressing the same degree of compression of the line 3 is achieved.
    For this purpose, in step 18 of FIG. 3, first a bar code 22 - see FIG. 1 - is optically evaluated on the connector 1 and the line 3, which in the example shown is a two-dimensional bar code 22 (data matrix) and a respective lot number of the connector 1 and the line 3 determined. On the basis of this information, it can be determined in a next step whether the now given batch constellation has changed compared to the batch constellation in the previous pressing process 25:12:47 28-10-2011 17/35 25. If this is not the case, then the pressing force need not be changed and the previously specified pressing force can be maintained. In this case, the process step 18 is completed at this point. When carrying out the first grouting process, the batch constellation must always be considered changed to the previous batch constellation.
    If a change in the batch constellation is found instead, it is determined in a next step whether the currently given batch constellation is already known or whether such a combination of a connector 1 from a specific batch and a line 3 from a specific batch has already been processed. If this is not the case, the presettable pressing force 19 for the new, unknown batch constellation is determined in an initial crimping process, so that as far as possible the same degree of crimping of the line 3 is achieved.
    In such an initial pressing operation, the connector 1 is positioned in the end region 2 of the line 3 and the pressing device 4 in the interior 9 of the line 3 and a pressing operation is performed. In this case, the forces occurring at the pressing portion 13 of the expanding jaws 12,12 'of the pressing device 4, measured on the inner layer 15 of the receiving portion 6 of the connector 1 and / or in the region of compression 14 of the line 3 and optionally also by the initial compression process achieved preferably achieved degree of compaction automated. Likewise, in an initial pressing operation in which a connector 1 and a line 3 are pressed at the same time, preferably the unpressed wall thickness 20 of the line 3 must be detected as an additional parameter, so that the forces occurring at the pressing section 13 of the expanding jaws 12,12 'in their components with respect to the connector 1 and the line 3 can be disassembled. From the data or information obtained in this way, the pressing force 19 to be predetermined for this new, unknown batch constellation is determined, stored for this batch constellation and given as the pressing force 19 for the immediately following pressing process. 16:13:36 28-10-2011 18/35 25
    -14-
    If the batch constellation to be processed in a pressing process is already known, the pressing force 19 stored therefor is called up and specified as the pressing force 19 for the immediately following pressing operation.
    A further possible embodiment of the method step 18 of the pressing method according to FIG. 2, in which method step 18 the pressing force 19 is predetermined for the pressing operation, is illustrated in FIG. 4 in a flow chart. The method step 23 before the method step 18, in which method step 23 a plug connector 1 and a line 3 are provided for processing, corresponds to the method step 23 in FIG. 2.
    After the provision of the connector 1 and the line 3 is at the beginning of the process step 18 of FIG. 4 are each a code from electromagnetically interrogatable transponders 24 - see Fig. 1, which transponder 24 (RFID tag) on the line 3 and on the connector 1 are arranged automatically read and the respective batch number of the connector 1 and the line 3 are determined.
    In a next step, it is determined whether the currently processed connector 1 and / or the currently processed line 3 comes from a batch marked as defective and in this case the connector 1 and / or the line 3 must be discarded. If such a separation is necessary, then the one or more rejected parts must be replaced again and also or the transponder 24 or the newly provided parts read again and the respective batch number can be determined.
    If both the connector 1 and the line 3 are each from a batch not marked incorrectly, then in a next step it is checked whether the currently present batch constellation is the same as that in the previous pressing process. If this is the case, the currently specified pressing force does not have to be adapted and method step 18 is completed at this point.
    If it is a batch constellation that was not processed in the last injection process, then in a next step it is determined whether a 25 16:14:24 28-10-2011 19/35 ** * ·· »» ·· * · «F -15-
    Connector 1 has already been processed from the present batch. If this is not the case, then the pressing force 19 and a corresponding correction value 32, 33 - see also Fig. 6 - determined for the pressing force 19 for this new batch of connectors 1 in an initial compression process, so that as possible the same Verpressgrad the line. 3 is reached. Oer correction value 32, 33 of the pressing force 19 indicates the value by which the pressing force 19, in particular starting from a normal pressing force, must be changed, so that as far as possible the same degree of pressing of the line 3 is achieved for the current batch of connectors 1 in each pressing operation.
    In a next step, it is determined whether the just-determined pressing force 19 falls below or exceeds a minimum value or a maximum value and thus lies outside a valid value range. If this is the case, then the batch from which the connector 1 for the initial compression process originates is marked as defective and the connector 1 is discarded. Subsequently, a new connector 1 must be provided for processing.
    If the pressing force 19 determined in the initial pressing operation is within the valid range, the correction value 32, 33 determined for the pressing force 19 is stored for the new batch of connectors 1 and the pressing force 19 is adjusted with the determined correction value 32, 33.
    The storage or storing in particular of correction values 32, 33 or values for the pressing force 19 takes place, in particular, in a data storage device, not shown, of a control unit of the injection device 4.
    If a connector 1 has already been processed from the now present batch in a preceding pressing process, then the pressing force 19 is adjusted with the correction value 32, 33 stored for this already known batch of connectors 1.
    In the further course of the method step 18 according to FIG. 4, as already described above for the connector 1, starting from the question whether a line 3 from the currently present batch has already been processed, the pressing force 25 16.15: 12 28-10-2011 25 20/35
    19 adapted with the corresponding correction value 32, 33 for the line 3, so that as far as possible the same Verpressgrad the line 3 is reached.
    If a line 3 from the currently present batch has not yet been processed, then the pressing force 19 and the corresponding correction value 32, 33 for the new batch of lines 3 are determined in an initial pressing operation with the line 3 alone, and if the determined pressing force 19 is outside is a valid range, the current present batch of lines 3 is marked as faulty and line 3 is discarded. In the other cuttings, the correction offset 32, 33 for the new charge train, which has just been determined in the initial compression process, is deposited and the injection force 19 is adjusted with the determined correction offset 32, 33 or the compression force 19 is compared with that for the already known charge of conduits 3 stored correction value 32, 33 adjusted.
    The determination of the corresponding correction values 32, 33 for the pressing force 19 in an initial pressing operation only with a connector 1 alone or only with a line 3 alone and the adjustment of the pressing force 19 with the correction values 32, 33 determined therefrom will be explained later Fig. 6 explained in more detail.
    FIG. 5 shows a third possible embodiment of the method step 18 of the pressing method according to FIG. 2, in which method step 18 the pressing force 19 for the pressing operation is predetermined.
    At the beginning of the transponder 24 - Fig. 1 - are read on the connector 1 and the line 3 and determines the respective batch numbers. The current batch constellation is determined far and only if the batch constancy is changed compared to the previous pressing operation is the pressing force 19 adjusted with the corresponding correction values 32, 33 for the present batch of connectors 1 and / or the present batch of lines 3 32, 33 for the present batch of connectors 1 or for the present batch of lines 3 not yet known 16:15:59 28-10-2011 21/35 25
    -17- is because a connector 1 or a line 3 has not been processed from such a batch, the pressing force 19 and the corresponding correction value 32, 33 for the pressing force 19 in the embodiment of FIG. 5 from data or information determined provided by the dealers or suppliers of the connectors 1 and / or the lines 3. Furthermore, the just-determined correction value 32, 33 is stored and the pressing force 19 is thus adjusted.
    After the adjustment of the pressing force 19 due to changes in the Char-gene constellation of the connector 1 and the line 3, it is determined whether changes have been made to the processing process. Such changes include, for example, maintenance or repair work on the pressing device 4. Was changed by such work, the processing process, the pressing force 19 with a corresponding correction value 32, 33 adapted to ensure the most consistent Verpressgrads.
    In FIG. 6, exemplary force profiles 25 to 28 on the pressing sections 13 of the spreading jaws 12, 12 * of the pressing device 4 are graphically represented during initial pressing operations only with a connector 1 alone or only with a line 3 alone. The force curve 25 was measured for a connector 1 from a specific batch S1. The force profiles 26 to 28 were determined for lines 3 from the batches L1 to L3.
    The different force profiles 26 to 28 over the path, which were covered by the expanding jaws 12,12 'of the pressing device 4, indicate a different stability or strength of the lines 3 from the different batches L1 to L3. If now the force curve 25 for the connector 1 from the charge S1 is in each case added to the force curves 26 to 28 of the lines 3 from the batches L1 to L3, then the total force profiles 29 to 31 result.
    In order to achieve a constant Verpressdicke 21 - see also Fig. 1 - and thus a constant Verpressgrad, since in the present case, the wall thicknesses 20 of the lines 3 from the individual lots L1 to L3 are the same, it is necessary, the pressing force 19 with correction waves 32, 33 adapt. 16:16:48 28-10-2011 22/35 25 ··· ♦ · · · · tl · «· * * ··« «* *» * «* · · * ·« * * * * * I · ·· I · • * Λ Λ • * * · «· ·» fr · -18-
    Assuming a line 3 from the batch L1 as the processed in the previous Ver-press operation line 3, so must the previously given Verpressekraft 19, which is the intersection of the vertical line at the point x (Verpressdicke 21) and the Total force curve 29 results in the correction value 32 can be reduced. This correction value 32 can be determined on the basis of the difference in the force profiles 26 and 27 at the location of the vertical line and thus based on the data obtained in the initial compression processes with lines 3 from the batch L1 or L2 alone.
    Equivalently, the correction value 33 for lines 3 from the batch L3 can be determined based on the difference in the force profiles 26 and 26 for the measured forces at the location of the vertical line and the pressing force 19 to be preset when processing a line 3 from the batch L3 Correction value 33 can be adjusted accordingly.
    In this connection, it is particularly expedient to specify the correction values 32, 33 relative to a nominal pressing force.
    For the sake of order, it should finally be pointed out that for a better understanding of the structure of the connector, the line and the Verpressvor-direction, these or their components have been shown partially uneven and / or enlarged and / or reduced.
    The embodiments show possible embodiments of the method for fixing a connector, it being noted at this point that the invention is not limited to the specific dargesteliten embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching technical action by objective invention in the skill of working in this technical field expert.
