    The invention relates to a connection of an electrical cable having metallic strands and a surrounding insulation, with a metallic contact part, wherein the insulation of the cable is removed in a region in front of one end of the cable, and wherein the contact part encloses the strands in the stripped area and at least partially compressed with these.
    In the connection of power supply lines, in particular those made of aluminum or aluminum alloys, which are increasingly preferred because of their price and weight, especially in the automotive industry over those of copper or copper alloys, with contact parts made of copper or copper alloys, are among other problems in the production of a resistance as possible and solve for corrosion as little as possible vulnerable connection. However, this problem occurs not only in connections of the aluminum cables with copper contact parts but whenever the material of the contact part in the electrochemical series differs to a significant extent from that of the cable. In addition, these compounds should be able to withstand the highest possible mechanical loads.
    According to the invention is proposed to solve these problems in a compound of the type mentioned that the contact part is connected to the strands by resistance welding.
    By combining resistance welding with mechanical compression, the alloy formed during welding creates an electrical connection between the materials of the welded parts which has low electrical resistance and, unlike purely mechanical connections by compression, is less susceptible to contact corrosion and crevice corrosion even if the connected materials in the electrochemical series are different.

    and a weld also creates a very high mechanical strength.
    According to the invention, these problems can also be solved in a connection of the type mentioned above in that a connecting cap is provided which at least partially surrounds the stripped part of the strands such that the contact part encloses the connecting cap, that by deforming the contact part and the connecting cap these together and are pressed with the strands of the cable and that the connecting cap is connected to the strands and to the contact part by resistance welding.
    The connection cap can additionally effect an electrochemical separation between the strands and the contact part, so that the critical connection area with the strands is less susceptible to corrosion. Therefore, in the context of the invention, it is particularly preferable if the strands are made of Jjjminium or an aluminum alloy, and the connecting cap is also made of aluminum or an aluminum alloy. Then, the contact part of copper or a copper alloy can be largely without problems.
    It is known to connect power supply lines in the automotive industry using the resistance welding method with contact parts. It is essential in the invention, the compaction of the conductor end or Litzenpakets by the contact part, with the possibly existing connection cap, before or during the welding is deformed inwards. It thus comes to a very good electrical connection, which is also mechanically very stable.
    When a connection cap closed at its end is used, the weld joint between the connection cap and the strands is sealed to this side and therefore less susceptible to corrosion, and therefore, it can be preferably used also in the wet area of the automobile. 06/06/2012 21:14

    In this connection, in the invention, it is preferable that a transition region between the connection cap and the insulation is insulated with a shrink tube or the like to completely insulate the connection between the conductor and the connection cap.
    Alternatively, it would also be possible to produce this insulation in other ways, for example, characterized in that the connection cap extends over the insulation, if necessary, is pressed with this, and is provided in this way for a suitable seal.
    The connection of the contact part with the connecting cap is also carried out using the resistance welding process, with which also different materials can be welded together well.
    The contact part has, in a preferred embodiment of the invention, at least in the region of connection with the connection cap or strands a separating layer of a material, preferably nickel, which lies in the electrochemical series between aluminum and copper, whereby a corrosion-resistant connection between the contact part and the connection «Cap or the strands is given.
    The contact part may be in the invention, for example, a battery terminal, a cable lug, a plug part or any other connection adapter.
    Further preferred embodiments of the invention are the subject of the remaining dependent claims.

    fourth perspective
    FIGS. 1 to 8 show a first embodiment of a connection according to the invention, which has a cable 1, a connection cap 2 and a contact part 3. The cable 1 consists in the illustrated embodiment of a bundle strands 4 or conductors and an insulation 5, wherein the end 6 of the insulation 5 has a distance from the end 7 of the strands 4 and the cable 1. This region, which is free from an insulation 5, can be produced in the course of the production of the compound according to the invention by removing an insulation 5 present in this region, if the insulation 5 has not already been removed or has not been applied at all in this region.
    The connecting cap 2 and the strands 4 are in the preferred embodiment described both made of aluminum or an aluminum alloy, so that it can not lead to stress corrosion in their connection. The connecting cap 2 is plugged in the production of the compound according to the invention on the non-insulated portion of the cable 1.
    In the illustrated Ausführungsfora, the connection cap 2 has a cylindrical sleeve 8 and an end wall 9, whereby the connection cap 2 is closed on one side.
    The contact part 3 consists in the illustrated embodiment substantially of a first part 10 and a second part 11. The first part 10 has an opening 12 through which a screw, not shown, can be inserted to contact part 3 according to the invention with another electrical Component to connect, for example, with a vehicle battery.
    The contact part 3 may for example be punched out of a sheet of copper, which is coated with nickel. To the second sleeve-shaped part 11 of the contact part 3 as in Fig. 1 06/06/2012 21:15

    In order to shape, the two cheeks 13, 14 can be bent together, to their edges with oppositely shaped tabs 15 and recesses mesh.
    As the drawings show, the sleeve 8 of the connecting cap 2 is preferably longer than the connecting cap 2 enclosing part 11 of the contact part 3. In particular, it is preferred if the sleeve 8 of the connecting cap 2 protrudes on the side facing the insulation over the contact part 3. Since the connecting cap 2 is closed on the side remote from the insulation 5 by the end wall 9, the contact or, connecting region between the connecting cap 2 and the strands 4 can be completely isolated from the environment by the transition region 16 or gap between the Connection cap 2 and the end 6 of the insulation 5 eg is sealed tight with a shrink tube, not shown, which can also lie over the protruding end of the Verbxndungskappe 2. ________ ________
    The outer diameter of the connecting cap 2 is preferably chosen so that it is not or only slightly larger than the outer diameter of the insulation 5. This facilitates the isolation described above.
    In the production of the compound according to the invention, the connecting cap 2 can first be pushed onto the stripped strands 4, as shown in FIG. Thereafter, the contact part 3 is pushed onto the connecting cap 2 and possibly slightly compressed with this and the strands 4.
    In an alternative embodiment, first, the connection cap 3 is inserted into the part 11 of the contact part 3, as shown in Fig. 3. If the inner diameter of the part 11 is smaller than the outer diameter of the connecting cap 2, the connecting cap 2 is pressed into the sleeve-shaped part 11. Alternatively, the connecting cap 2 also with play in the sleeve-shaped part Π 06/06/2012 21:15

    Pressing the part 11 of the contact part 3 with the connection cap 2 and pressing the connection cap 2 with the strands 4 is not absolutely necessary but advantageous in this phase of the production, i.a. to prevent shifting of the parts relative to one another before the welding operation is carried out. In addition, a pressing of the connecting cap 2 with the strands 4 lead to an advantageous compacting of the strands 4 in the connecting cap 2, which can subsequently improve the welding of the strands with each other and with the connecting cap 2.
    This pressing of the connecting cap 2 with the strands 4, which, as mentioned, but not absolutely necessary, can be done only over part of the length of Verbindunqskappe 2. A________.
    However, compression over the entire length or almost over the entire length would of course also be possible.
    After the joint has been prepared so far, it is completed in a per se known resistance welding device by the strands 4 with the connecting cap 2 and the connecting cap 2 with the part 11 of the contact part 3 under the action of. Electric power to be welded. During the action of the current flowing through the part 11, the connecting cap 2 and the strands 4 transversely and melting or softening these components in the area of action of the stream at least partially, the part ll and by this force from the outside also pressed the connection cap 2 to the strands and into the strand bundle, so that the contact part 3, the connecting cap 2 and the strands 4 not only cohesively but also positively connected to each other. The force for this deformation is preferably directly through the electrodes attached to the sections 17, 18. Welding device 06/06/2012 21:16

    · · · · · · · · · · ·. It can also be applied by another tool.
    Preferably, the part 11 and through this also the connecting cap 2 is pressed from opposite sides to the strands and into the strand bundle, so that the pressed-in sections 17 and 18 are formed. But one-sided impressions would also be possible. If the connection cap 2 and the contact part 3 are pressed inwards only on one side of the connection, this section 17 is preferably located on the side opposite the tabs 15, since the part 11 of the contact part 3 is more stable in shape here. An annular or elliptical compression would also be possible, for example.
    The sections 17, 18, in which the contact part 3 is pressed by the connecting cap 2 with the strands 4 of the cable 1 and plastically deformed, is preferably in the immediate welding area, since here the positive connection between the individual parts is the most stable. For the same reason, it is preferred in the invention, when the connecting cap 2 and the contact part 3 are plastically pressed inwardly only over a part of their length, since the adjacent, non-compressed or deformed portions increased resistance to displacement of the parts offer against each other. In particular, it is preferred if the inwardly pressed portions 17, 18 are spaced from the end 7 of the cable.
    In the context of the invention, it is also possible to carry out the pressing and thus deformation of the part 11 with the connecting cap 2 inwards towards the strands 4 with simultaneous compression of the strands 4 at least partially before the welding process, whereby this is again preferred only in a part of the length of the connecting cap 2 and the part 11 can take place.
    In any case, it is in the invention of advantage, although not essential, the pressing force upright to 06/06/2012 21:16

    hold until the connecting cap 2, the part 11 and the strands 4 have cooled down after the welding process to such an extent that they no longer deform when the pressing force is released.
    A further embodiment of the invention is shown in FIGS. 9 to 15, which largely corresponds to the embodiment of FIGS. 1 to 8, but has no connecting cap 2. The strands 4 are therefore received directly in the sleeve-shaped part 11 of the contact part 3 and pressed there, as in particular Figs. 9, 10 and 11 show. However, the manufacturing method can be carried out as described above for the embodiment of FIGS. 1 to 8, in particular by pressing the part 11 together before and / or during the resistance welding process in the sections 17 and / or 18 and thereby also the strands 4 are pressed together at least in sections.
