Definitions
- the invention relates to a connection of an electrical aluminum cable, in particular of an aluminum cable formed and insulated from a plurality of aluminum wires or fitzen with a copper, copper alloy and / or brass connecting part, for example with a battery terminal, a cable lug, a connection adapter, a Plug part, a piece of cable or the like, for the electrical system of a motor vehicle, the insulation of the aluminum cable ends before the point of contact with the connector or is removed and a support sleeve is provided, which encloses at least the end side of the stripped portion of the aluminum cable adjacent area and pressed with the end of the aluminum cable and / or shrunk onto it, so that the wires of the aluminum cable are compressed at least in the region of the front side.
- the invention further relates to a method for connecting an electrical aluminum cable with a copper, copper alloy and / or brass connection part, for example battery terminal, cable lug, connection adapter, plug part, cable or the like, for the electrical system of a motor vehicle, wherein the front side the aluminum cable is brought into contact with and electrical contact with the end face of the connection part and the aluminum cable is stripped at the connection end, pressed or shrunk onto the stripped point, and the wires or strands of the aluminum cable are pressed together.
- a copper, copper alloy and / or brass connection part for example battery terminal, cable lug, connection adapter, plug part, cable or the like
- the connector itself it is not possible to make the connector itself also made of aluminum, because in the range of batteries or accumulators acid vapors can not be completely ruled out that attack aluminum to a much greater extent than copper, copper alloys or brass, and because connections to An internal combustion engine connected units such as alternators are exposed to such a high dynamic load that from it over time the less stable material aluminum is broken or the connection connection is destroyed.
- Aluminum also presents a greater risk of corrosion than copper, which has relatively good corrosion resistance because aluminum is relatively non-noble and therefore tends to transition to the more stable oxide form from which it was generated by using energy.
- metals of different nobility are conductively connected, there is a risk of contact corrosion. Due to their noble potential, the copper materials are less endangered than aluminum, but can have a harmful effect on this metal when combined with it. Since aluminum is the less noble metal compared to copper, it may happen in a Berzier für at high currents and longer exposure times, especially in humid, salty climate that the less noble metal, so the aluminum acts as a "sacrificial anode" and decreases. Over time, material loss occurs at the contact surface, which negatively affects contact resistance and strength.
- the aforementioned compound of an electrical aluminum cable with a connection part according to claim 1 or 9 is formed.
- the compound is thus characterized mainly by an additional support sleeve on the aluminum cable, which stabilizes the individual wires or strands by squeezing enough and approaches each other to give a metallic surface on the front side of the cable, which then simultaneously the junction or the point of This makes it possible to rid this end of oxide, if there should have formed, and then to weld this end face butt with the connection part, so that in the future no oxide can arise at this point.
- aluminum can certainly be fused and welded to copper and thus even form a mutual alloy on the compound according to the invention. Experiments have shown that the tensile strength of such a compound can be higher than that of the aluminum cable and / or the fitting itself.
- this submetallic compound layer can be approximately 2 mm thick, so that access of air or moisture to this connection point is excluded
- the support sleeve extends over the transition between the stripped region of the aluminum cable and the insulation, enclosing part of the insulation.
- the support sleeve thus expediently obtains a greater axial length than the stripped region of the aluminum cable, so that a good stiffening is achieved in the region of the junction to below the insulation, resulting in a uniform distribution of the compressive forces in the connection area, without overburdening and deforming the individual aluminum wires too much.
- a junction is also lateral forces and dynamic loads, as they can occur in motor vehicles also connected to the engine units, grown.
- a good sealing of the aluminum cable and the connection can be achieved.
- one end of the support sleeve is flush with the end-side end side of the stripped region of the aluminum cable.
- the support sleeve then increases the connection point in the radial direction and is also available for welding with a suitably sized fitting or counterpart, provided that the end of the aluminum cable compressing support sleeve is a metal sleeve, in particular an aluminum sleeve.
- an aluminum sleeve has the advantage that it behaves in terms of thermal expansion, electrical conductivity and weldability as the aluminum cable itself, so to speak is a supplement of the aluminum cable at the junction.
- the aluminum cable and the shrunk-on or pressed-on support sleeve and the connecting part have a substantially circular cross-section, in particular of the same size.
- the weld can then extend over the entire cross section of the compound and at the same time the entire cross section of the connecting part on the one hand and the healing of aluminum cable and support sleeve formed on the other.
- Correspondingly favorable resistance values for the electric current can be achieved at this large-area connection.
- the support sleeve for pressing or Vorverpressen the aluminum cable in its interior has at least two sections of different inner cross-section or inner diameter and the portion with the larger inner diameter of the end of the insulation of the Aluminum cable and the area of smaller inner cross-section encompasses the stripped area of the aluminum cable.
- the difference of the inner diameter of the support sleeve can correspond to about twice the thickness of the insulation of the aluminum cable.
- connection can be completed by butt welding. It is particularly advantageous if the provided with the support sleeve end of the aluminum cable is connected to the connection part by friction welding. Friction welding is known per se and in many cases thereby causing one of the parts to be rotated prior to the connection, then to move against the other part, creating a frictional heat high enough to weld the parts so that they firmly bond together after the rotation has been decelerated. Especially when connecting an aluminum cable with a connection part can thereby be automatically eliminated at the junction or end face of the aluminum cable oxide layer automatically because such a layer is penetrated and removed by the mechanical friction. Thus, an electrical connection of an aluminum cable with a connection part by friction welding to be regarded as particularly advantageous and favorable, especially since relatively low energies for this type of welding, for example, against a conceivable Abbrenn-butt welding are necessary.
- the above-mentioned method is to achieve the object, characterized in that the individual wires or strands of the aluminum cable are butt welded together with the support sleeve with the connecting part.
- the soft and resilient end of the aluminum cable first through a support sleeve is mechanically strengthened to withstand the stresses of the weld and make this end face of the aluminum cable suitable for direct welding with a connector, because this results in a practically closed, formed from the individual wires or strands of the aluminum cable metallic surface.
- the support sleeve is arranged with one end flush with the end face of the aluminum cable, that is, one end of the support sleeve is used to increase the front side of the aluminum cable and thus the connection point and used.
- one end of the support sleeve is used to increase the front side of the aluminum cable and thus the connection point and used.
- the individual wires or strands of the aluminum cable actually on the one hand all squeezed together and solidified with each other and yet are accessible to the weld.
- These wires can be flush with each other and form a flat front or cross-sectional area.
- a particularly favorable procedure may consist in that the aluminum cable provided with the support sleeve is connected to the connection part by friction welding. Compared to an electrically assisted butt welding method significantly less energy is required for this advantageously. Nevertheless, the friction welding method allows a welding of the aluminum materials on the one hand and copper or copper alloy on the other hand to form intermetallic phases, that is, the oxide layer on the aluminum is destroyed and eliminates the Korrosions personallykeft at the junction Since the aluminum cable is pressed with the support sleeve before or later than at the same time with the welding process , creates a kind of solid cylinder, at its front or top surface, the welding can be done.
- connection part to be connected or butt-welded to the aluminum cable is rotated and pressed in rotation against the end face of the aluminum cable and is fused or welded by the frictional heat generated after the rotation is decelerated.
- the friction and the frictional heat could be caused by other mutual relative movements, but the rotation has the great advantage that the parts to be joined in the transverse direction can already assume their final position and an almost arbitrary number of revolutions can be generated on the rotating part to get enough frictional heat for welding.
- any oxide layer on the aluminum side may be penetrated and removed in a particularly effective manner.
- the wires or strands of the aluminum cable can be compressed before and / or during the welding process at least in the area of the terminal-side connection point, which can be carried out particularly easily with the support sleeve mentioned above.
- the support sleeve on the outside surface in particular to a polygonal, for example, to a hexagon, be pressed. This results in addition to the later assembly the possibility for a tool attack, for example, for the attack of a wrench.
- a polygonal shape on the outside of the support sleeve in the installation and installation of the cable with its connector may be advantageous.
- the connecting part may be either a cylinder made of copper or a copper alloy, for example made of brass, which in turn is connected to a corresponding connector or a cable clamp or Batteriekiemme or the like or is already connected in one piece with it from the outset.
- a cylinder can be rotated particularly well and connected by friction welding with the appropriately prepared aluminum cable.
- connection part to be connected to the aluminum cable can in turn be a cable piece made of copper wires, which is also stabilized by means of a support sleeve, so that a Reibsch spacci is made possible in particular by rotation preferably of the copper part, in which then the cable itself and the support sleeves connected and welded together.
- a device for carrying out the method for connecting an aluminum cable with a connector may consist in particular in that an openable clamping device for the provided with the support sleeve aluminum cable and arranged in alignment with releasable support for the connection part are provided, that the holder has a rotary drive or so that it can be coupled and that the clamping device and the holder are movable or displaceable relative to one another in the direction of longitudinal extent of the aluminum cable and of the connecting part which is thus aligned at least in the case of mutual contact. It is particularly favorable if the rotating holder is displaceable. This displaceability then includes the required pressing force at the connection point, which is exerted during the welding. In this case, the openable clamping device for the end of the aluminum cable can be used simultaneously for pressing the support sleeve provided therefor.
- the joint itself has a high electrical conductivity, because a previously possibly on the aluminum side and possibly even on the copper side existing oxide layer can be eliminated by friction welding at a relative mutual rotation, so that the two different metals get into intermetallic phases and fused together and be welded.
- connection part 1 which consists of individual aluminum wires 2 and an insulation 3 with a connection part 4
- matching parts are given the same reference numbers.
- FIG. 2 shows a generally designated V connection of the electrical aluminum cable 1, which is formed of individual aluminum wires 2 or optionally made of strands and provided with the insulation 3, with a copper, copper alloy and / or brass connecting part 4 shown.
- Fig.2 shows a connection V of the aluminum cable 1 with a battery terminal 5, Figure 4 Such a connection with a cable lug 6, Figure 6 a connection with a connection adapter 7, which may also be a Stekkerteil with connector pins 8, and Figure 8 the connection V of an aluminum electrical cable 1 with a piece of cable 9 made of copper, a copper alloy wherein also individual wires 10 and an insulation 11 are provided.
- FIGS. 1 . 3 . 5 and 7 it can be seen clearly that the insulation 3 of the aluminum cable 1 before the - not acted on in these figures later - touch point, ie ends before the end-side end face 12 or is removed, so that the aluminum cable 1 is therefore stripped at the end to be connected, and that a support sleeve 13 is provided, which according to the already mentioned Figures 2 . 4 . 6 and 8 the outer end side 12 of the stripped portion of the aluminum cable 1 adjacent area in the position of use encloses the outside.
- the support sleeve 13 may thus first placed in the longitudinal direction of the outside to be connected and stripped end of the aluminum cable 1 and pressed or shrunk, so that the wires 2 of the aluminum cable 1 are compressed at least in the region of the end face 12, so that practically a solid cylinder is formed in the finished connection V is the connecting part 4, which may be designed differently according to the individual embodiments, with the end face 12undauch the support sleeve 13 welded.
- the connection point V is further marked by a diameter plane of the compound V hinting transverse line, although in the welding no separation point or joint remains, but the two metals of the connected parts due to a through the Welding heat fusion are jointlessly connected.
- the support sleeve 13 extends over the transition between the stripped region of the aluminum cable 1 and the insulation 3, enclosing part of the insulation 3.
- the support sleeve 13 thus serves not only to compress the wires 2 and to form the already mentioned solid cylinder, the welding on the end face 12 and thus the welding of the individual wires 10 or strands of the aluminum cable 1 with the connecting part of copper or a copper alloy or brass Since the support sleeve 13 is pressed or shrunk onto the aluminum cable 1 and thus also to the end of its insulation 3, the end of the insulation 3 becomes firmly fixed to the wires 2 as well connected to the aluminum cable 1, so that a high waterproofness is achieved.
- the one end 13a of the support sleeve 13 in the use position is flush with the end face 12 of the stripped portion of the aluminum cable 1 and the wires 2, so that so the already mentioned solid cylinder on the front side 12 of the aluminum cable 1 is practically enlarged by the existing there thickness of the support sleeve 13 and represents a correspondingly enlarged area for connection to the connector part 4.
- the aluminum cable and the shrunk or pressed Stutzhutse 13 on the one hand and the connector 4 on the other hand have a substantially circular cross section of the embodiment in each case the same size, as it is both in the initial position of the parts before their mutual connection as well as after completion of the compound V respectively recognizes
- the support sleeve 13 compressing the end of the aluminum cable 1 is a metal sleeve and in particular an aluminum sleeve, but possibly also a copper or brass sleeve, it takes part in the welding process and in the formation of the weld seam 14 and at the same time improves the mutual connection of the parts because thus not only the flat, flat face 12 is connected to the connector 4, but also the end 13 a of the support sleeve 13, on the other hand extends beyond the insulation 3 and possibly occurring dynamic tensile or shear forces well distributed.
- the support sleeve 13 has in its interior two sections of different inner cross-sections or inner diameter.
- the section 13b with the larger inner diameter surrounds the end of the insulation 3 of the aluminum cable 1
- the section 13c of smaller inner cross section surrounds the stripped region of the aluminum cable 1.
- the difference between the inner diameters of these two sections 13b and 13c of the support sleeve 13 corresponds to twice the thickness of the Insulation 3 of the aluminum cable 1, that is, the difference in the inner radii of the two sections 13b and 13c of the support sleeve 13 correspond approximately to the thickness of the insulation 3, so that despite the gradation between the insulated and the stripped portion of the aluminum cable 1, the outside of the support sleeve 13 in can be substantially smooth and without heel or diameter change.
- connection V In order to produce the connection V, therefore, the aluminum cable 1 is first stripped at the connection end by either the insulation 3 is removed to a certain length or omitted from the outset. Thereafter, the support sleeve 13 is pressed or shrunk, whereby the wires 2 or strands of the aluminum cable 1 are compressed, so that there is virtually a Voliquerrough on the end face 12 despite the formation of these individual wires 2, for welding to the connector 4 available stands. Thereafter, the aluminum cable 1 is butt welded together with the support sleeve 13 with the connection part 4, which may be designed differently according to the individual embodiments. Due to the welding heat and a mutual compressive force in the longitudinal direction of the parts to be joined results in the bead-shaped weld 14th
- the support sleeve 13 In the initial position and also after the connection V has been produced, the support sleeve 13 is flush with the end face of the aluminum cable 1 with one end 13a. This allows the aluminum cable 1 provided with the support sleeve 13 to be connected to the connection part 4 by friction welding.
- the connecting with the aluminum cable 1 and blunt to be welded connection part 4 is rotated in a manner not shown in rotation and rotating at high speed, for example, 1500 Umdr./Min. pressed against the end face 12 of the aluminum cable 1 and the end 13a of the now pressed support sleeve 13 and fused and welded by the resulting frictional heat after braking and stopping the rotation, in the region of the compound V then the metals of the connected parts also alloyed together become.
- the wires 2 or strands of the aluminum cable 1 are thus compressed before and during the welding process at least in the region of the frontal connection point V to form the already mentioned solid cross-section with a flat, flat face 12.
- the support sleeve 13 is on the outside surface, in particular to a polygon, for example, to a hexagon, pressed so that a largely uniform compression of the wires 2 in the region of the connection V and the support sleeve 13 later outside well with tools during assembly are detected can.
- Fig.2 Can be connected to the aluminum cable 1, a battery terminal 5 with connecting pin 5a as Anschiußteil 4.
- connection part 4 which is designed as a cable lug 6 with a bolt-shaped connection part 6a
- connection of the aluminum cable 1 is shown with a connection adapter 7 for cohesive electrical connections, for example via Stekkerlixe 8, wherein the connection adapter 7 itself has the corresponding cross-sectional shape and surface for blunt welding with the aluminum cable 1.
- Fig.7 and 8 shows the ability to connect an aluminum cable 1 with a piece of cable 9 in particular copper or a copper alloy as a connector 4, said serving as a connector 4 cable piece 9 of wires 10 made of copper or a copper alloy on its outside also with a support sleeve 13 in particular Copper, a copper alloy or brass or aluminum, in each case made of metal, pressed and butt welded to the front side 12 of the aluminum cable 1.
- this support sleeve 13 is made of copper or the like flush with the cable piece 9 at the end, so that the connection V takes place both on the respective wires 2 and 10 and the support sleeves 13, that is, over a correspondingly enlarged cross-section with appropriate stability.
- a device for carrying out such a method is not shown in detail and expediently comprises an apparent clamping device for the provided with the support sleeve 13 aluminum cable 1 and arranged in alignment with detachable and rotatably driven holder for the connection part 4.
- the jig and the holder are then relative to each other in the direction of longitudinal extension of the aluminum cable 1 and thus aligned at least in mutual contact terminal part 4 movable or displaceable, so that the rotating pressed against the fixed part and thereby the necessary friction heat for Reibsch spavorgang can be generated.
- the rotating holder is expediently displaceable, dasie receives the total shorter or smaller connector part 4 After braking the rotary drive takes place under the resulting friction heat mutual fusion and welding practically over the entire cross section, which is not only a solid but also a tight connection V results
- the aluminum wires 2 are protected and protected and despite this compression not so much deformed that they can no longer withstand later dynamic loads.
- connection V of the aluminum electric wire 1 with a fitting 4 made of copper or a copper alloy is effected by squeezing the wires 2 forming the aluminum cable 1 in the end portion and welding to the fitting 4, in particular by a friction welding method.
- the frictional heat between the materials is used to melt both materials and without additional welding material together connect to.
- the Aluminiumkebel 1 is provided with a pressed-it with support sleeve 13, which makes the individual wires 2 at the junction practically a full surface and is welded together with the connection part 4.
