    Descriptive Report of the Invention Patent for PROCESS FOR ELECTRICALLY CONDUCTIVE CONNECTION OF A BEAM OR WIRE BEADED BY ULTRASOUND ACTION.
    [001] The invention relates to a process for the electrically conductive connection of a bundle of wires provided with insulation, particularly an insulating varnish, the insulation being removed, at least partially, by means of ultrasound action and, optionally, the beam is received, before the ultrasound action, by a coating of metallic material. The invention also makes reference to an arrangement for the positive fitting connection of a bundle of insulated wires, particularly wires provided with an insulating varnish, by means of ultrasound, the bundle being able to be arranged in a compression chamber of an ultrasound welding device, which on opposite sides is limited by a sonotrode, which emits ultrasound vibrations, and an anvil and, laterally, by side jaws, optionally adjustable.
    [002] To connect materials by positive fitting, it is possible to use ultrasound welding. In this case, the energy required to weld is introduced in the form of mechanical vibrations in the product to be welded. For this purpose, a sonotrode is placed in ultrasound vibration in its longitudinal direction. Simultaneously, there is a relative movement of a counterelectrode associated with the sonotrode - also called an anvil - to produce a necessary static welding force. Between the counterelectrode and sonotrode are the materials to be joined.
    [003] In ultrasound welding, a distinction is made between plastic ultrasound welding and metal ultrasound welding. In plastic welding, heating in the weld region occurs by absorbing mechanical vibrations, by reflecting the turns in the weld region and by
    Petition 870190058535, of 6/25/2019, p. 10/38
    2/16 friction of contact surfaces in the joining area. The vibrations are introduced vertically, that is, the longitudinal axis of the sonotrode extends vertically to the plane extended by the counterelectrode, on which the joining components are arranged. Typical frequencies in plastic ultrasound welding are between 10 kHz and 70 kHz.
    [004] Contrary to plastic welding, in metal ultrasound welding, mechanical vibrations are introduced parallel to the extended plane in front of the anvil. In this case, there is a complex relationship between the static force acting between sonotrode and counterelectrode, the oscillating shear forces and an increase in temperature in the union zone. Typical frequencies in metal ultrasound welding are between 20 kHz and 40 kHz, with the characteristic frequency usually being in the range of 20 kHz.
    [005] In both plastic ultrasound welding and metal ultrasound welding, the joining area is located in the belly of vibration.
    [006] Document DE-B-102 29 565 discloses a process for electrically conductive connection of varnished wires. In this chaos, the varnished wires are surrounded, at least partially, by an electrically conductive material in the regions to be connected, to subsequently frictionally connect the wires with the material by ultrasound, to a simultaneous rupture of the insulation varnish. .
    [007] In order not to need to isolate varnished wires before welding, according to document DE-A-196 36 317, they are introduced into a receiving space of an ultrasonic welding device, limited by an anvil, and the sonotrode and / or the anvil have a profile.
    [008] Insulated wires, according to JP-A-22075481, are surrounded by a constitutive coating
    Petition 870190058535, of 6/25/2019, p. 11/38
    3/16 of electrically conductive material, which is then connected with the wires in an ultrasonic welding device. The sonotrode has a W-shaped geometry, in section, and the sonotrode has a continuous extension in relation to the anvil.
    [009] Document JP-A-4370669 describes a process for connecting electrically insulating conductors to a cable terminal. For insulation, ultrasound acts on the wires. At the same time, folding strips are folded to secure the wires to the cable terminal.
    [0010] To connect an electrical conductor surrounded by insulation with a connection, they are placed next to each other, to then obtain a positive fit connection by means of ultrasound (US-A-6,009,366).
    [0011] To connect wires wrapped with insulation with a connection, document US-A-4,317,277 provides for a metal element, which has protrusions, which run through the insulation and surround the wires.
    [0012] The present invention is based on the task of, on the one hand, improving a process and an arrangement of the type mentioned initially in such a way that a secure positive fit connection between insulated wires is possible, particularly wires with a varnish isolation. At the same time, there should be a simplification compared to known processes. For a good electrically conductive connection, high mechanical strength must be ensured.
    [0013] On the other hand, the invention is based on the task of also connecting bare wires or strands, which in themselves can lead to welding problems.
    [0014] To solve the task, the invention provides, substantially, that in a first step, the insulation of the wires is removed, at least partially, by means of plastic ultrasound welding,
    Petition 870190058535, of 6/25/2019, p. 12/38
    4/16 and in a second step, that the wires are connected by positive fitting by means of ultrasonic welding or resistance welding, or that the wire bundle is received by the metallic coating, such as the wrapper, and the metallic coating is disposed with its longitudinal axis transversely to the longitudinal axis of a sonotrode, which transmits ultrasound vibrations and that by means of ultrasound welding the partial removal of the insulation is carried out, as well as the positive connection of the wires with each other and with the metallic coating . In that case, a cavity is formed simultaneously, such as the annular notch transversely to the longitudinal axis of the metallic coating, such as the shell. If the removal of the insulation preferably takes place in a step preceding a positive fitting connection to the coating, then, surprisingly, at least partial removal of the insulation can also occur during welding on the coating.
    [0015] Corresponding wires, equipped with insulating varnish, usually have diameters of at least 0.3 mm, with preferred diameter ranges between 0.4 mm and 1.5 mm, without the design according to the invention should be limited. In the case of wires, these are, in principle, solid copper or aluminum wires or copper wires or aluminum alloys. A mixture of materials, therefore, yarns of different materials, is also possible. In this chaos, to obtain sufficient rigidity, a steel wire may also be contained in the wire bundle, without the sonotrodes' stability times being shortened; as the metallic coating - such as a molded sheet piece - prevents direct contact between the sonotrode and the wires.
    [0016] There are also advantages, particularly in the welding of aluminum wires, also with larger cross sections; as the housing offers protection against sticking or forming
    Petition 870190058535, of 6/25/2019, p. 13/38
    5/16 league.
    [0017] Also tinned wires can be welded without problems.
    [0018] A separation of the branches from the wires is avoided due to the wrapping.
    [0019] A bundle of wires with different cross sections can be welded without problems by means of ultrasound. The weakening normally found when welding wires with different cross sections does not occur, due to the metallic coating.
    [0020] According to the invention, a two-stage process is preferably used, by means of which the insulation was first sought, that is, the insulation varnish is broken and displaced, and then in a second connect the wires, with insulation removed, at least in sections, by positive fit to each other. This is preferably done by means of ultrasound, although welding of the wires, with insulation removed, at least in sections, is also possible by means of resistance welding.
    [0021] When the removal of the insulation and the positive fitting connection do not take place in two process steps, but must be carried out in a single process step, the alternative proposal of the invention foresees that the bundle of the wires is introduced in a wrapper or corresponding coating and it is aligned in such a way with respect to the sonotrode, which transmits ultrasound vibrations, from an ultrasonic welding device, that the longitudinal axis of the housing or the coating extends transversely to the longitudinal direction of the ultrasound vibrations therefore, transversely to the longitudinal axis of the sonotrode. In such an arrangement, it was surprisingly shown that the insulating varnish is also broken and removed to the extent necessary to then make possible a positive fit connection. At the same time, there is a deformation of the
    Petition 870190058535, of 6/25/2019, p. 14/38
    6/16 casing or coating, which by the force acting on the sonotrode in the ultrasound welding, obtains the cavity, as notch, transversely to the longitudinal direction, with which the connection between the casing and the wires with removed insulation is reinforced.
    [0022] The longitudinal axis of the sheath or sheath - hereinafter, for reasons of simplification, in principle, as sheath - extends in the direction of the wires, therefore, in the longitudinal direction of the bundle of wires to be welded.
    [0023] Preferably, in a two-step process course, it is envisaged that the wires, after welding by plastic ultrasound, are wrapped by a wrapper and then connected by a positive fit, together with the wrapper. In this case, the longitudinal axis of the enclosure, with the wires, can be aligned in the longitudinal direction of the ultrasound vibrations, when the ultrasound is applied during the metal ultrasound welding.
    [0024] However, an introduction of the compacted wires to a knot by plastic-metal welding, in a wrapper is not necessarily necessary.
    [0025] When a casing is used, then there is still the possibility of arranging its longitudinal axis transversely to the ultrasound vibrations, so that, in this case, a notch results, as previously explained.
    [0026] Particularly good welding results can be obtained when the wires are compacted during plastic welding are compacted to a first quadriform shape, with a height H1 in the longitudinal direction of the ultrasound vibrations and a width B1 across the longitudinal direction and, then, the wires are deformed during the ultrasound welding of metal to a second quadriform shape, with a height H2, with H2 <H1 and a width B2, with B2> B1.
    Petition 870190058535, of 6/25/2019, p. 15/38
    7/16 [0027] In addition, the wires can be connected by positive fitting during metal ultrasound welding with a support. Often, in this case, it is not necessary for the wires with the insulation removed previously to be wrapped in a wrapper.
    [0028] In order to feed the wires to a compression chamber of an ultrasonic welding device, to exclude that the wires are so far apart from each other that a smooth insertion is not possible, in an improvement of the invention it is provided that the wires, at least during the welding with plastic ultrasound welding, are received by a fixation aid or wrapped by it. In this case, a fixing liner can be used as a fixing aid. A tool can also be used, which only feeds the compression chamber around the bundle of wires.
    [0029] The removal, at least partially, of the insulation, waste water and rupture of the varnish, can be carried out in a first workstation, while the connection by positive fitting, is carried out in a second workstation.
    [0030] In a configuration of the invention to be highlighted, however, it is envisaged that plastic ultrasound welding and metal ultrasound welding can be carried out in the same workstation, whereas in plastic ultrasound welding, the sonotrode for metal ultrasound welding is the anvil in plastic ultrasound welding, and in metal ultrasound welding, the sonotrode for plastic ultrasound welding is the anvil for metal ultrasound welding.
    [0031] In the rupture of the insulation varnish, during the action of ultrasound there is a partial evaporation of the insulation varnish and it burns it. In order to prevent the positive fitting connection from being impaired during ultrasonic metal welding, the invention provides
    Petition 870190058535, of 6/25/2019, p. 16/38
    8/16 that the bundle of wires is requested in the region of the ends of the wires in the plastic ultrasound welding, and the bundle is compacted to a quadriform shape, and then, after the plastic ultrasound welding, separate, as cut, the free end of the compacted bundle. As a result, varnish residues that still exist between the wires are additionally removed.
    [0032] The invention is also distinguished by a process for the electrically conductive connection of a bundle of strands or bare wires by means of the ultrasound action, the beam being received, before the ultrasound action, by a metallic coating, such as as a coating of metallic material, due to the fact that the beam is received by the metallic coating and the metallic coating is arranged with its longitudinal axis transversely to the longitudinal axis of a sonotrode, which transmits ultrasound vibrations and the connection is made by positive fitting of the wires or cords to each other and with the metallic coating by means of ultrasonic welding, and simultaneously, transversely to the longitudinal axis of the metallic coating, a cavity is molded in it. In a corresponding process, the characteristics explained above can be used correspondingly.
    [0033] In addition, the positive fitting connection of a bundle of insulated wires, particularly wires provided with an insulating varnish, by means of ultrasound, the bundle being able to be arranged in a compression chamber of a ultrasound welding, which is limited on opposite sides by a sonotrode, which generates ultrasound vibrations and an anvil and laterally, by optionally adjustable side jaws, due to the fact that the arrangement has a first and a second sonotrode, whose longitudinal axes are cut at a right angle, the arrangement is suitable for both metal ultrasound welding and ultrasound welding

    9/16 plastic sound and that in metal ultrasound welding, the second sonotrode is not excited and the anvil for the first sonotrode can be excited, and in plastic ultrasound welding, the first sonotrode is not excited and the anvil stops the second sonotrode and the second sonotrode can be excited. With the arrangement the process characteristics of the description above can be used.
    [0034] Other details, advantages and features of the invention are evident not only from the embodiments and features to be found therein - alone or in combination - but also from the description below of preferred modality examples found in the drawing.

    [0036] In the figures, in which equal reference signals are used in principle for example, examples of modality or cases of application of a process according to the invention for the positive connection of wires provided with a insulation, in the case of wires 10, these are preferably varnished wires. The wires to be welded are previously

    10/16 gathered for a bundle. In order to avoid a gap, the beam 12 may be surrounded by a fixing aid in the form of a ring 14 or an envelope, as it is visible, in principle, only in the figures.
    [0037] To compact the bundle 12 of the 10 isolated wires, which have diameters between 0.3 mm and 1.5 mm, and therefore are sufficiently rigid, and connect them electrically conductively, ultrasound welding is used plastic, in combination with metal ultrasound welding, the latter of which can optionally be replaced by resistance welding.
    [0038] Figure 1 shows, in principle only, an ultrasound welding arrangement, to explain the essential elements. In that case, the arrangement 110 is explained by means of an ultrasonic welding device 111, which is intended for welding metals.
    [0039] The ultrasonic welding arrangement 10 comprises as essential elements a converter 112 and a sonotrode 114, among which is a booster for amplification amplitude.The converter 112, booster 116 and sonotrode 114 form a so-called vibrator of ultrasound 117, which is mounted on the booster 116. The sonotrode 114, that is, the head of the same, not visible in figure 1, is associated with a counterelectrode 115, to which the vibrator 117 can be lowered, to introduce forces on the components weld connection. In addition, side slides are present to adjust the compression chamber, surrounded by the sonotrode 114, counterelectrode or anvil 115 or by the side slides, to the desired extent in height and width. Counterelectrode 115 is formed, in particular, in multiple parts, as described, for example, in US-A-4,596,352.
    [0040] Converter 112 is connected via a line 118 with a generator 120, which, in turn, is connected via a
    Petition 870190058535, of 6/25/2019, p. 19/38
    11/16 line 122 to a computer. Through the generator 120, the converter 112, that is, the piezocrystal discs, are requested with high frequency voltage, to expand or contract the discs accordingly, with which ultrasound vibrations are generated, with an amplitude, which, intensified by the booster, can be transmitted to the sonotrode114.
    [0041] According to the invention, the varnish insulation of the wires 10 assembled into a bundle 12, is broken and displaced by means of ultrasound. The rigid wires 10 form the necessary resistance in the introduction of ultrasound and force, so that the varnish can crack. At the same time, compaction occurs. This only occurs in a plastic ultrasound welding device 26, as can be seen, in principle, in figure 2.
    [0042] When the wires are not sufficiently rigid, a steel wire can be inserted in the bundle, with which the desired or necessary rigidity can be obtained, in order to apply ultrasound, remove the insulation or varnish or let it crack .
    [0043] A corresponding steel wire does not lead to the fact that the sonotrode is exposed to higher wear, as long as the beam, as explained below - is received, before welding, by a coating or metallic shell, which is welded with the beam.
    [0044] An essential component of the corresponding device 26 is a sonotrode 28, which is mounted on the vibration node. Sonotrode 28, which in the example of modality is a λ / 2 vibrator, has a sonotrode head 30 with a frontal surface, which extends parallel to the support surface 32 of a counterelectrode 34, on which the beam 12 is positioned . The sonotrode 28 is excited to vibrate in the direction of its longitudinal axis, so that by the arrangement of the sonotrode 28 and its welding surface formed by the front surface of the sonotrode head. The longitudinal axis of the wires
    Petition 870190058535, of 6/25/2019, p. 20/38
    12/16 or beam 12 inside the compression chamber consequently extends vertically to the longitudinal axis of sonotrode 28. To introduce ultrasound vibrations, sonotrode 28 is lowered correspondingly, in the direction of a beam 12 not shown . The compression chamber limited, on the one hand, by the front surface of the sonotrode head 30 and, on the other hand, by the weld surface 32 of the anvil 34, can be closed laterally by slides not characterized in more detail, in order to adjust the width.
    [0045] The corresponding process step can also be found in figure 5a and is characterized with 1. Thus, the bundle 12 of the wires 10, which are surrounded by the fixing casing 14, is introduced in a corresponding compression chamber of a device of ultrasound welding, which corresponds to figure 2. With the application of ultrasound, there is a rupture and displacement of the varnish, a simultaneous compaction of the beam 12 inside the compression or welding chamber, so that, according to the peripheral geometry of the compression chamber, a quadriform geometry results in the compacted terminal region 36 of the beam 12.
    [0046] By the action of ultrasound, as mentioned, the insulation varnish of the wires 10 is simultaneously broken and displaced. Partial evaporation also occurs. If there is too large a quantity of varnish burned in the terminal region, which constitutes a hindrance in subsequent process steps, the free end of the terminal region 36 transformed in a quadriform manner must be separated.
    [0047] After the beam 12 exposed to plastic ultrasound welding has been removed from the compression chamber (step 2 in figure 5a), in the example of the modality, over the terminal section 36 of the beam 12 a connection sleeve is inserted or a so-called annular cable terminal 38 (process step 3). The respective unit is then placed
    Petition 870190058535, of 6/25/2019, p. 21/38
    13/16 in a compression chamber of a metal ultrasound welding device 40, to make the positive plug connection between the annular cable terminal 30 and another element, such as sheath or plate and the wire bundle 12, released from varnish insulation, at least partially existing. In this case, there is the possibility of placing the connection loop in the longitudinal direction of the sonotrode 42 (vertically to the drawing plane) or - as is visible, in principle, in figure 5b - transversely, therefore, in the direction of the arrow 5. In this case, the longitudinal axis of the annular cable terminal 38 extends vertically to the longitudinal axis of the sonotrode, with the consequence that in the action of force and transmission of ultrasound, according to the geometry of the sonotrode in the belly of the vibrations, in which the sonotrode acts on the annular cable terminal 38, a notch is formed (see removal section 6 in figure 5b). As a result, a positive-fit and friction connection between the annular cable terminal 38 and the beam 12 is further strengthened.
    [0048] Instead of the annular cable terminal 38, the bundle 12 can also be received by a metallic sheath with appropriate geometry.
    [0049] In the modality example of figure 5, a sonotrode 41 is used as a sonotrode λ, which is mounted on one end and acts at a distance λ / 2 from the front end 44 on the annular cable terminal 38.
    [0050] When the annular cable terminal 38 is positioned parallel to the longitudinal axis of a sonotrode in the welding by metal ultrasound, then a deformation occurs in the longitudinal direction of the annular cable terminal 38, as it should be illustrated, merely in principle, by the lower representation, on the right, in figure 5b.
    [0051] In other words, the wires 10 connected by positive fitting with the annular cable terminal 38 and, previously, partially
    Petition 870190058535, of 6/25/2019, p. 22/38
    14/16 released from the insulation, were positioned in the lower representation on the left, in figure 5b, in the alignment of the annular cable terminal 38 across the longitudinal axis of the sonotrode and, in the lower representation, on the right, parallel to the longitudinal axis of the sonotrode, in the compression chamber, not specified in more detail, [0052] The measurements and process steps, which were explained in connection with figures 4 and 5 for the positive plug connection of insulated wires to each other and with the annular cable terminal , are correspondingly valid for a positive plug connection of bare cords or wires to each other and with a corresponding annular cable terminal 38 or another metallic sheath of suitable geometry, in which, after ultrasound welding, it is molded in the connection terminal. annular cable 38 or in the sheath a notch, extended transversely to the longitudinal direction of the same, corresponding to the notch 44 according to figu ra 5b.
    [0053] Figure 3 shows a detail of an ultrasonic welding device 46, with which wires10 released from the insulation in sections are connected by positive fitting to each other. In the embodiment example, the wires 10 are aligned parallel to the longitudinal axis of a sonotrode 48. In that case, it is not necessary for the wires 10 to be received by a wrapper after removing the insulation. On the contrary, the wires 10 can be welded, for example, with a plate, which is positioned on an anvil 50 of the ultrasonic welding device 46. It is also possible to see side slides 52, 54, which limit the compression chamber laterally. .
    [0054] There is also the possibility that, first, bundles 12 of the wires 10, partially released from the insulation, are compressed into a knot and welded, without a connection with another metallic element occurring.
    [0055] According to the design according to the invention, the
    Petition 870190058535, of 6/25/2019, p. 23/38
    15/16 removal of insulation from wires 10 can be carried out on a first workstation - such as that in figure 2 - and additional compaction and positive fitting connection to each other and, for example, with a support or a wrapper, on a second workstation according to figure 3.
    [0056] From the example of modality in figure 4, another alternative is evident, according to which both the at least partial removal of the insulation of the wires 10 and the connection by positive fitting of them take place in a single workstation . For this purpose, it has two sonotrodes 28, 48 according to figures 2 and
    3. In this case, the sonotrodes 28, 48, with their heads 30, 49, are aligned in such a way that they have a dual function, namely, on the one hand, they serve to transmit the necessary ultrasound vibrations and, on the other hand, they perform the function of an anvil.
    [0057] If in the compression chamber according to figure 4, limited by the sonotrode heads 30 49, the insulation of the wires 10 must be removed, then the sonotrode head 49 of the sonotrode 48 serves as an anvil. Sonotrode 28 then emits ultrasound vibrations to break the varnish or insulation. Consequently, a plastic welding process is carried out.
    [0058] If, subsequently, a positive fitting connection should be made, optionally, after the insertion of a coating on the bundle 12 of the wires 10, then the sonotrode head 30 of the sonotrode 28 serves as a counterelectrode or anvil, while the sonotrode 48 is excited for ultrasound vibrations and transmits them to the materials to be joined. A metal welding process takes place.
    [0059] If the insulation 10 of the wires 10 is removed first and then a weld with the sheath, such as annular cable terminal 38 or any other sheath, formed by
    Petition 870190058535, of 6/25/2019, p. 24/38
    16/16 example, by a molded sheet, then, normally, the insulation of the wires 10 is removed outside the sheath over a section of a few millimeters. This region 37 is limited by two annular limits on the one hand, the opening 39 of the casing 38 and, on the other hand, the edge 43 of the insulation of the wires 10. This region 37 can be surrounded, without problems, with a flexible contraction tube 45 for insulation of the wires 10.
    [0060] Regarding the wires 10 to be welded, it should be noted that they do not need to consist of the same material and do not need to have the same cross section. On the contrary, a mixture of materials can be welded. Wires 10 with a different cross section can also be soled.
    [0061] The designs according to the invention also apply to bare wires or strands, which can be connected by positive fitting in one and with a coating.
    [0062] The welding of cords or wires in the metallic housing, consequently, is also covered by the design according to the invention, and in the welding, the housing is arranged with its longitudinal axis transversely to the longitudinal axis of a sonotrode, to shape transversely a cavity in the coating axis.
    [0063] If in the examples of modality the design according to the invention was explained by means of insulated varnish wires, therefore, which have a hard insulation, it is also possible to apply to other wires, provided with a soft insulation.
