Definitions
- the present invention relates to a method for connecting a connecting element made of copper or a copper alloy for a cable, in particular a cable lug, to an electrical cable which has a conductor consisting of aluminum.
- connection elements in particular cable lugs
- glue them together using an electrically conductive plastic material, to solder or weld them together, or to connect them to one another in a form-fitting manner by deformation or compression.
- electrically conductive plastic material to solder or weld them together
- connect them to one another in a form-fitting manner by deformation or compression.
- existing connecting elements are not in direct contact, since otherwise, if a liquid acting as an electrolyte acts on these connections, an electrochemical process occurs, by which the aluminum nium existing conductors are destroyed, whereby the electrical and mechanical connection is destroyed.
- the object of the present invention is therefore to provide a method by which an aluminum conductor can be permanently connected to a connection element made of copper or a copper alloy. This is achieved according to the invention in that a layer of a metal lying in the electrochemical series between aluminum and copper, in particular nickel or a nickel alloy, is provided between the electrical conductor made of aluminum and the connecting element made of copper or a copper alloy.
- the position of the metal lying in the electrochemical voltage series between aluminum and copper is preferably applied, in particular welded, to the end face of the electrical conductor.
- the weld can be produced in particular by means of a powder welding process.
- a plate of a metal lying in the electrochemical series between aluminum and copper, in particular nickel or a nickel alloy, can be applied, in particular welded, to the aluminum conductor.
- connection element can be formed by a flat plate made of copper or a copper alloy, which is connected, in particular welded, to the aluminum conductor with the interposition of a layer of a metal which lies in the electrochemical series between aluminum and copper.
- the plate can then be bent into an elbow, with the connection point for the aluminum conductor on one leg and a connection point for making an electrical connection, e.g. a hole.
- a sleeve made of a metal lying in the electrochemical series between aluminum and copper can be applied to the aluminum conductor, the connection part can be placed on this sleeve and these components can be welded together, Soldering and / or mechanical deformation are firmly connected.
- the sleeve applied to the conductor is made of steel.
- a sleeve or clamp made of copper or a copper alloy is formed on the conductor made of aluminum, which is provided at least on its side facing the conductor with a coating consisting of metal, in particular nickel, in the electrochemical series between aluminum and copper , whereupon the sleeve or clamp and the conductor are connected to one another by deformation and / or by soldering.
- the sleeve or clamp can be connected to the aluminum conductor by soldering the end face of the conductor to the sleeve.
- the subject invention further relates to an electrical cable with an electrical conductor, which is formed with at least one connection part, in particular a cable clamp, wherein according to the invention the electrical conductor is made of aluminum and the connection part is made of copper or a copper alloy, and between which electrical conductor and the connection part is a layer of a metal lying in the electrochemical series between aluminum and copper, in particular nickel.
- the electrical conductor and the connecting part can be connected to one another by mechanical deformation and / or soldering or welding with the interposition of the layer of a metal lying in the electrochemical series between copper and aluminum.
- FIG. 1 shows a cable with an electrical conductor made of aluminum and a cable lug, which are connected to one another according to a first embodiment of the method according to the invention, in a side view, partially in section,
- FIG. 2 shows a cable with an electrical conductor made of aluminum and a cable lug, which according to a second embodiment form of the method according to the invention are connected to one another, partially cut,
- FIG. 4 shows a cable with a conductor made of aluminum and a cable lug, which are connected to one another according to a fourth embodiment of the method according to the invention, partially cut, and
- FIG. 5 shows a cable with a conductor made of aluminum and a cable lug, which are connected to one another in accordance with a fifth embodiment, partially cut.
- an electrical cable 1 which consists of a conductor 11 made of aluminum, which is surrounded by insulation 12. The stripped free end of the conductor 11 is tightly enclosed by a sleeve 13 made of aluminum.
- the cable 1 is assigned a pole piece 2 made of brass, which is to be attached to the conductor 11.
- the pole piece 2 consists of an L-shaped angled plate with two legs 21 and 22, wherein there is a bore 23 in the leg 21 with which it can be placed on the pole pin of a battery.
- the leg 22 projecting from the leg 21 at a right angle serves to be connected to the conductor 11.
- a powdery layer 3 of a metal which is in the electrochemical series between aluminum and copper, in particular nickel, is applied to the end face of the conductor 11 and this layer is applied to the conductor 11 welded. Subsequently, the layer 3 and the leg 22 of the pole piece 2 are brought into contact with one another and they are welded together.
- the conductor 11 is also surrounded by a sleeve 13 made of aluminum.
- a plate 3a made of nickel is welded onto the end face of the conductor 11. The connection surface for the welding process is enlarged by the sleeve 13 made of aluminum. Subsequently, this plate 3a is welded to the pole shoe 2 made of brass.
- the pole piece 2 can also be designed as a flat plate which is welded to the end face of the conductor 11, this plate then being bent into the angled pole piece 2.
- the layer 3, 3a of the metal, in particular nickel can initially be applied to the pole piece 2, which is then connected to the conductor 1.
- a sleeve 3b made of a metal lying in the electrochemical series between aluminum and copper is placed on the free end of the aluminum conductor 11 and a sleeve-shaped part 24a of a cable lug 2a is pushed over this sleeve 3b. whereupon these two sleeves 3b and 24a are mechanically and electrically connected to one another by compression and deformation.
- This cable lug 2a is also formed with a bore 23.
- the sleeve 3b is e.g. made of steel.
- the sleeve 24b of a pole piece 2b is placed on the conductor 11 made of aluminum, which has at least on its inside assigned to the conductor 11 a coating 3c made of a metal lying in the electrochemical series between aluminum and copper, in particular made of nickel, the sleeve 24b and the conductor 11 being mechanically and electrically connected by deformation.
- the end face of the conductor 11 is also formed with the sleeve 24b with a soldering 4.
- the aluminum conductor 11 of the cable 1 is not directly connected to the connection element 2, 2a, 2b, which is made of copper or a copper alloy, but that there is a layer 3, 3a, 3b between these two components , 3c, which consists of such a metal, which lies in the electrochemical series between aluminum and copper, whereby the risk of decomposition of the conductor 11 made of aluminum is very much reduced.
- the decisive factor for the desired effect is that aluminum has a standard potential of -1,676 volts and copper has a standard potential of at least 0.337 volts, each measured against a normal hydrogen electrode.
- the potential frequency between these two metals causes the aluminum to decompose in the presence of an electrolyte.
- the standard potential of which is between that of aluminum and copper
- the metals in the electrochemical series between aluminum and copper are manganese, zinc, chromium, iron, cobalt, nickel, tin, lead and tungsten.
- the desired effect can be achieved by means of all of these metals or also by means of alloys or mixtures of these metals. Nickel and zinc are particularly suitable for this purpose, since their standard potentials are in the middle range between those of aluminum and copper.
