DETAILED DESCRIPTION

[0068] FIG. 1A shows a schematic illustration of a crimping apparatus 1 according to one embodiment of the invention, and FIG. 1D shows a cable 4 with a contact sleeve 3, respectively loose and crimped with one another. The contact sleeve 3 is a turned contact sleeve 3.

[0069] The crimping apparatus 1 is an indent crimping apparatus and in particular a four-indent crimping apparatus having a crimping device 2 having four pressing elements 20, which are particularly suitable for compressing a stripped cable or a strand of a stripped single-core cable 4 with a turned contact sleeve 3. The pressing elements 20 are suitably designed as pointed mandrels 20.

[0070] To actuate the crimping device 2, the crimping apparatus 1 has a pneumatic pressure device having a cylinder 10 and a piston 11, which is operationally connected via a lever 130 to the crimping device 2. For a configuration described at the outset of a predetermined crimping height by way of adjustment mandrels, a suitable setting mechanism 12 is provided, which can have an adjustable stop for the lever 130.

[0071] In the case of a crimp by way of compression of a contact sleeve 3, which is turned in particular, with a cable 4, the contact sleeve 3 with the strand of the cable 4 located therein is inserted as intended into the crimping device 2, and the crimping device 2 is actuated by way of the pressure device and pressure is applied thereto. The lever 130 coupled to the crimping device 2 is pivoted by way of a vertical movement and a vertically acting force F of the pressure device. The crimping device 2 and the lever 130 are designed and arranged in such a way that the mandrels 20 are moved toward one another from the rest position P0 thereof or moved into the rest position P0 thereof during a pivot, which is described hereinafter with reference to FIG. 1B. The tips 21 of the mandrels 20 are each located on concentric circles, which is described hereinafter with reference to FIGS. 2B and 2C.

[0072] The crimping apparatus 1 is suitably configured for checking the quality of a crimp of a predetermined cable 4 with a predetermined contact sleeve 3 and has for this purpose a travel sensor 13 and at least one force sensor 14. The travel sensor 13 can suitably be a position transmitter having a Hall sensor and can be provided on the cylinder 10 of the pressure device. The force sensor 14 can suitably be a piezoelectric sensor 14 and can be arranged on the lever 130 and/or can be at least one piezoelectric sensor provided on a fastening of the cylinder 10. The piezoelectric sensors each measure an elongation or tension during the actuation of the lever 130 or the counter force acting on the cylinder 10 of a pressure acting on the piston 11.

[0073] The sensor system 13, 14 is connected to transmit signals and/or data to an evaluation electronics unit 5. The evaluation electronics unit 5 can control a display screen and can display a force/travel curve G of a crimp, which is acquired using the signals of the sensor system 13, 14, together with further items of information on the display screen. Examples of a force/travel curve G are described hereinafter with reference to FIGS. 2A and 3A.

[0074] FIG. 1B shows an enlarged illustration in more detail of the crimping device 2 and FIG. 1C shows an enlarged mandrel 20 of the crimping device 2 from FIGS. 1A and 1B. For the sake of clarity, the force sensor 14 on the lever 130 is not shown in FIG. 1B.

[0075] The crimping device 2 has a cylindrical guide having the cylinder axis A, in which four mandrels 20 are mounted so they are radially movable. The tips 21 of the mandrels 20 are oriented toward one another. The lever 130 is axially pivotably or rotatably mounted on the cylindrical guide and has an inner contour which interacts with heads of the mandrels 20 protruding out of the cylindrical guide.

[0076] Upon a pivot of the lever 130, the tips 21 of the mandrels 20 are moved toward one another or away from one another in the direction of the axis A of the cylindrical guide or the pivot axis of the lever 130. The tips 21 of the mandrels 20 are each located on concentric circles. In a crimp, a contact sleeve 3 provided with a cable 4 is compressed with the cable 4 in this way by means of actuation of the lever 130 on the axis A of the cylindrical guide.

[0077] The crimping device 2 with its mandrels 20 is additionally described hereinafter with reference to FIGS. 2B, 2C, and 4A.

[0078] A crimping apparatus 1 having the above-described features is suitable for carrying out a method described at the outset and hereinafter also with reference in particular to FIG. 4, FIG. 4B, and FIG. 5.

[0079] FIG. 2A shows a force/travel curve G of a crimp of a contact sleeve 3, which is carried out by way of a crimping apparatus 1 from FIG. 1A, with a cable 4 from FIG. 1D according to one embodiment of the invention.

[0080] The mandrels 20 of the crimping device 2 are moved during the crimp from the rest position P0 thereof into further positions P to P1, wherein the tips 21 of the mandrels 20 move toward one another and are each arranged on concentric circles. A travel X and a force F, which are represented by the force/travel curve G, are measured by the sensor system 13, 14. The positions P0, P, P1 each correspond to particularly characteristic positions P of the mandrels 20 for the course of the force/travel curve G and the analysis thereof to assess the quality of a crimp and each correspond to a measured travel X of the sensor 13.

[0081] FIG. 2B shows an enlarged illustration of the crimping device 2 from FIG. 1A in the rest position P0, together with a contact sleeve 3 arranged as intended for crimping in the crimping device 2 and a cable 4. The tips of the mandrels 20 of the crimping device 2 are arranged concentrically with the contact sleeve 3 and the cylindrical guide of the crimping device 2, which has the axis A.

[0082] A displacement of the mandrels 20 from the position P0 to the position P adjacent to the position P0 in FIG. 2A takes place using a constant force F. The course of the force/travel curve G is accordingly also constant in a first range P0-P between the position P0 and the position P of the mandrels 20, in which the mandrels 20 of the crimping device 2 touch the surface of the contact sleeve 3.

[0083] FIG. 3B shows an illustration, which is enlarged and in more detail in relation to FIG. 2B, of a section through a contact sleeve 3 provided as intended for the crimp with a cable 4. The interior of the contact sleeve 30 has, in addition to individual wires 40 of the strand of the cable 4, a cavity not claimed by the individual wires 40 of the strand. The contact sleeve 3 is intact and its state corresponds to the contact sleeve 3 from FIG. 2B in the range P0-P of the crimp with the force/travel curve G.

[0084] FIG. 2C shows the mandrels 20 of the crimping device 2 at the position P1 of the mandrels 20 corresponding to the position P1 of the force/travel curve G, wherein the tips of the mandrels 20 are arranged on a circle having a diameter H, which corresponds to the set crimping height H. With the mandrels 20 arranged at the position P1, the strand completely fills up the available space in the contact sleeve 3. This state of the contact sleeve 3 and the strand is shown in a microsection of the contact sleeve 3 for the region P1 from FIG. 3C, in which no individual wires 40 of the strand are recognizable and no cavity is present in addition to the strand. FIG. 3C shows a microsection of a crimp having a desirable predetermined quality, in which no individual wires 40 or cracks in the contact sleeve 3 are recognizable due to, for example, undesired material deficiencies.

[0085] FIG. 3A shows further force/travel curves G, G3, and G4 of a crimp together with two envelope curves GH of a reference model, which is suitable for checking the quality of a crimp.

[0086] The two envelope curves GH are each shown by dot-dash lines in FIG. 4A and delimit a tolerance range T. The force/travel curve G of FIG. 4A is shown by a solid line and lies in its entire course from the position PO to the position P1 of the mandrels 20 between the envelope curves GH and corresponds to a crimp of a contact sleeve 3 with a cable 4 having a predetermined desirable quality, having a microsection as described above with reference to FIG. 3C. A crimp having such a desirable quality is achieved in particular using intact, undamaged pressing elements 20, whereupon monitoring of the state of the pressing elements 20 is desirable.

[0087] FIG. 5 shows a flow chart of a method for monitoring the state of a crimping device 1 according to one embodiment of the invention. Reference is additionally made to FIG. 4A and the table of FIG. 4B to illustrate the method.

[0088] FIG. 4A shows an enlarged illustration of a pressing element 20 of a crimping device 2 in its rest position P0 in a first operating state having a first configured crimping height H(1) and in a second operating state having a second configured crimping height H(2). In the first operating state, the pressing element 20, which is formed as a pointed mandrel, is undamaged and/or new, and in the second operating state, the point of the pressing element 20 is worn. The positions of the tips of the pressing element 20 define the positions P0(1) and P0(2).

[0089] FIG. 4B shows a tabular list of data measured and/or ascertained and/or calculated and/or recorded during a configuration of a crimping height.

[0090] As stated at the outset, for the sake of simplicity, a reference crimping height H(1) of an actual crimping height H1 or a reference crimping height H(2) of an actual crimping height H2 is respectively used as the crimping height H(1) and H(2), which each correspond to half the crimping height H1 and H2, and wherein the reference crimping heights H(1) and H(2) are referred to for the sake of simplicity and clarity as crimping height H(1) and H(2). The crimping heights H(3) and H(n) of Table 3 of FIG. 4B are also respectively a reference crimping height H(3) and H(n) referred to as the crimping height H(3) and H(n) for the sake of simplicity and clarity.

[0091] The pressing elements 20 of FIG. 4A are formed as pointed mandrels 20 and are suitable for a crimping device 1 of FIG. 1A.

[0092] In a first step S1 of the method of the embodiment of FIG. 5, during a configuration E(n), a configuration E(1), E(2), E(3), E(n) of a crimping height H(1), H(2), H(3), H(n) is respectively carried out The pressing elements 20 of the configuration E(1) can be in a new and unused state, which is shown on the left side of FIG. 4A. The pressing elements 20 of the further configurations E(2), E(3), E(n) can be in a used and/or worn state, wherein the further configuration E(2) of a comparatively worn pressing element 20 is shown on the right side of FIG. 4A.

[0093] During a configuration E(n) of the configurations E(1), E(2), E(3), E(n), in a second step S2, a travel X(1), X(2), X(3), X(n) of the pressing elements 20 of the crimping device 1 from a first P0(n) to a second position P1(n) is measured, wherein the pressing elements 20 are in the rest position P0 thereof in the first position P0(n) and are in a working position P1 in the second position P1(n), which corresponds to the set crimping height H(n).

[0094] During a configuration E(n), in a third step S3, the comparison of the travel X(n) of the configuration E(n) to a travel X(n-1) of a configuration E(n-1) of a crimping height H(n-1) carried out before the configuration E(n) of the crimping height H(n) is carried out in a suitable way by means of subtraction of the measured travel, namely ΔX(n)=X(n)−X(n-1). In the first configuration E(1) of a crimping device having new pressing elements 20, this difference is ΔX(n)=0. In the second configuration E(2) of the crimping device 2 having used pressing elements 20, which correspondingly differ from the pressing elements 20 of the configuration E(1), this difference is ΔX(2)=X(2)−X(1). The configuration E(n-1) is in this case respectively the last configuration carried out before the configuration E(n), wherein the travel X(n-1) of the configuration E(n-1) is read out in the third step S3 of the method from data recorded during the configuration E(n-1) in a fourth step S4.

[0095] In the fourth step S4, data for further configurations E(n) are recorded. The data can comprise at least the travel X(n) and/or the above travel difference ΔX(n) of a configuration E(n). Upon recording of the travel difference ΔX(n), the possibility is advantageously provided in the third step S3 of additionally summing over all recorded differences ΔX(n) of all configurations E(n) carried out, namely of forming the sum Σ ΔX(n), wherein summing is carried out from 1 to n. In the first configuration E(1), Σ ΔX(1)=0 and ΔX(1)=0 in this case.

[0096] In a fifth step S5, in each case a comparison of the difference ΔX(n) to a predetermined deviation is carried out and in a sixth step S6, a signal is output if the comparison fulfills a predetermined criterion. The above comparison carried out in the fifth step S5 can be ascertained here, for example, from the ratio and/or the difference of the deviation with/from the difference ΔX(n). The predetermined criterion can be a predetermined difference and/or a predetermined ratio.

[0097] The data read out in the third step S3 and/or the data recorded in the fourth step S4 of a configuration E(n) can moreover comprise, in addition to the travel X(n) and/or the difference ΔX(n), additionally the number n of the configurations E(n) carried out and/or the respective configured crimping height H(n).

[0098] It is additionally advantageous in the third step S3 to compare the crimping height H(n) to the second crimping height H(n-1), wherein the comparison can be derived from the ratio thereof and/or in particular the difference thereof, namely ΔH(n)=H(n)−H(n-1), wherein the data read out in step three and/or the data recorded in step S4 can additionally comprise the difference ΔH(n). In this way, the possibility is advantageously provided of carrying out a plurality of configurations E(n) having different crimping heights H(n). Monitoring of the operating state of the pressing elements 20 is therefore advantageously often also possible routinely upon configuration of different crimping heights H(n).

[0099] Otherwise, only one configuration E(n) of a crimping height H(n) can be used to carry out the method according to the invention, the crimping height of which corresponds to the crimping height H(1) of the first configuration (1). In the first configuration E(1), ΔH(1)=0 and ΔX(1)=0 in this case.

[0100] In this way, the possibility is additionally advantageously provided, in addition to the above-described sum Σ ΔX(n) over all recorded differences ΔH(n), of summing all configurations E(n) carried out, namely forming the sum Σ ΔH(n), wherein summing is performed from 1 to n. In the first configuration E(1), Σ ΔH(1)=0 and ΔH(1)=0 in this case.

[0101] In addition, the data read out in step S3 and/or the data recorded in step S4 can suitably additionally comprise the sums Σ ΔX(n) and Σ ΔH(n), whereby the possibility is advantageously provided in step S3 of additionally taking into consideration ΔX(n) and ΔH(n) of all configurations by means of formation of the ratio and/or the sum thereof. The sum Σ ΔH(n)+ΔX(n), namely Σ ΔH(n)+ΔX(n), can suitably be formed here, wherein summing can be performed over all configurations E(n) carried out.

[0102] The sum Σ ΔH(n)+ΔX(n) can be compared in the fifth step S5 to a predetermined deviation, wherein a signal is output in the sixth step S6, if this comparison fulfills a predetermined criterion. The data read out in the third step S3 and/or the data recorded in the fourth step S4 can suitably additionally comprise the sum Σ ΔH(n)+ΔX(n) here.

[0103] The sum Σ ΔH(n)+ΔX(n) is particularly advantageous for checking for the presence of a criterion of the comparison V having the predetermined deviation, because in this way arbitrarily many configurations E(n) having arbitrarily many crimping heights H(n) can be used for the method according to embodiments of the invention.

[0104] The data recorded in step S4 can be recorded suitably with respective association with a configuration E(n). For example, the recorded data of a configuration E(n), namely n, X(n), H(n) and/or ΔX(n) and/or ΔH(n) and/or Σ ΔX(n) and/or Σ ΔH(n) and/or Σ ΔH(n)+ΔX(n) can be stored in tabular form here in corresponding lines and columns. FIG. 4B shows an example of retrievable stored data in a table.

[0105] Upon recording of the sum Σ ΔH(n)+ΔX(n) of a configuration E(n), in addition all data can be erased which are associated with other configurations E(n). In this way, it is advantageously possible to keep a storage space required for the recorded data small.

[0106] A method according to embodiments of the invention can additionally have a further step in a suitable manner, in which the crimps C carried out after configuration E(n) of a crimping height H(n) are counted, namely the number #C(n), and the number #C(n) is recorded together with the above recorded data, whereupon the data read out in step S3 can additionally comprise the number #C(n).

[0107] In this way, the possibility is advantageously provided that the signal output in step S6 can comprise, in addition to a predetermined criterion and/or the sum Σ ΔH(n)+ΔX(n), the number #C(n) and/or its sum Σ#C(n), whereupon during a configuration E(n) of a crimping height (n), an estimation can be performed of a suitability to be expected of the pressing elements for a number of crimps to be carried out. It is clear that during a configuration E(n) in step S4 of the method, the sum Σ#C(n) can respectively also be recorded.

[0108] Aspects and features of the various embodiments described above can be combined to provide further embodiments. These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
