Definitions

  • the invention relates to a method for connecting an electrical line to an electrical connection element.
  • Electrical lines in particular those used in vehicles for power supply or for the transmission of electrical control signals, are conventionally formed of copper material and connected to electrical connection elements made of copper material, which facilitate the connection of the electrical lines to vehicle components.
  • the invention has for its object to provide a method by which a permanently mechanically stable and electrically conductive connection between an electrical line with at least one aluminum wire and a connection element of a different material of the aluminum wire metal material can be produced.
  • the method of claim 1 is for connecting an electrical line to an electrical connection element, wherein the electrical line has at least one aluminum wire and the connection element is formed from a different metal material from the material of the aluminum wire.
  • the method comprises crimping a crimping section of the connecting element with the at least one aluminum wire, and additionally welding it to the at least one an aluminum wire crimped crimping portion of the connecting element with the at least one aluminum wire by means of resistance welding.
  • the inventive method thus combines two connection processes, namely the crimping of the crimping section with the at least one aluminum wire on the one hand and the subsequent resistance welding on the other hand. This combination ensures a permanently mechanically stable and electrically conductive connection between the electrical line and the connecting element.
  • a mechanical connection is first made between the at least one aluminum wire and the crimping portion, which has preliminarily sufficient mechanical stability and electrical conductivity.
  • an existing on the at least one aluminum conductor oxide layer is already at least partially broken and reaches a certain electrical conductivity between the aluminum line and the connection element by crimping.
  • the electrical line has a plurality of aluminum wires, not only the individual aluminum wires are crimped with the connection element during crimping, but the aluminum wires are also squeezed together, resulting in an improved conductivity also between the individual aluminum wires.
  • An optimal mechanical stability and electrical conductivity of the compound is finally achieved according to the invention in that after crimping with the at least one aluminum wire crimped crimping section is additionally welded to the at least one aluminum wire, that is, so a cohesive connection between them is created.
  • so much electrical energy is supplied to the crimping area that the at least one aluminum wire and the connection element are melted in their contact area and existing oxide layers are at least approximately completely broken, whereby the contact resistance between the connection element and the at least one aluminum wire is further reduced.
  • a particular advantage of the method according to the invention consists in the fact that the crimping force exerted during the crimping on the crimping section and the at least one aluminum wire can be lower due to the additional welding than in the case of conventional crimping connections in which no welding takes place.
  • the oxide layers of the individual wires are broken and the wires are at least partially fused together so that there are also reduced contact resistances and better electrical conductivity between the wires.
  • a permanently electrically conductive and mechanically stable connection can be produced between an aluminum line and a connection element, which is formed from a metal material that differs from the material of the aluminum line. Different materials can also be different aluminum alloys.
  • At least two electrodes are brought into contact with the connection element during resistance welding, and a current flow is generated between the electrodes via the connection element and the at least one aluminum wire.
  • a current flow is generated between the electrodes via the connection element and the at least one aluminum wire.
  • Suitable electrodes may, for example, comprise a tungsten material.
  • connection element can be clamped between the electrodes. As a result, a good mechanical stability of the overall arrangement is achieved during the resistance welding.
  • a clamping force can also be exerted on the connection element by the electrodes, which is of the same order of magnitude as a force exerted on the connection element during crimping. In this way, during the resistance welding an additional compression of the connection element with the at least one aluminum wire, which leads to an even better connection between the two.
  • connection element In order to keep the connecting element and the at least one aluminum wire during the resistance welding even safer, the Connection element are additionally clamped during resistance welding between two electrically insulating retaining elements. Because the holding elements are designed to be electrically insulating, a short circuit between the electrodes via the holding elements is avoided. Particularly suitable are holding elements which comprise a ceramic material, since they have a particularly high mechanical stability with a high electrical insulation effect.
  • crimping forms an F-crimp connection or a hexagonal crimp connection.
  • the crimping section has two free crimping tabs, which form a receptacle into which the at least one aluminum wire is inserted, wherein the crimping tabs are crimped onto the aluminum wire during crimping, which is usually in and for both crimping tabs the same pressing process takes place.
  • the two Crimperiel can thereby be connected by a base portion of the crimping portion and be formed so that the crimping portion assumes a substantially U- or V-shaped cross section before crimping.
  • the crimped blades can be bent so that the free ends of the crimping blades point in the direction of the at least one aluminum wire and are pressed against the aluminum wire.
  • a hexagonal Crimped connection can be produced, for example, using a crimping tool with hexagonal internal cross section.
  • a crimp section with a closed crimp barrel also proves to be advantageous because it ensures in a simple manner during subsequent resistance welding that the electrodes placed on the crimp section do not come into direct contact with the at least one aluminum wire.
  • the crimp sleeve of a hexagonal crimp connection has two substantially parallel and flat outer surfaces on which the electrodes used for the resistance welding step can be applied in a particularly simple and large-area manner.
  • the crimping section of the connecting element is provided with indentations on its inner side facing the electrical line and, during crimping, material is forced into the indentations of the at least one aluminum wire.
  • the recesses are formed so that they are only partially filled during crimping by the material of the at least one aluminum wire.
  • the depressions are similar to a greater extent of the at least one aluminum wire due to the different thermal expansion coefficients of aluminum and copper compared to The connection element when heated and can therefore be referred to as compensation wells.
  • the material of the aluminum wire when heated, may expand into the areas of the recesses left free after crimping, without the copper material being forced outward by the expanding aluminum.
  • a sufficient mechanical and electrical contact with the connection element is ensured even with a cooling of the aluminum and a corresponding contraction, since the aluminum is always at least partially in contact with the lying between adjacent recesses protrusions of the connection element.
  • the depressions thus contribute to avoiding a loosening of the connection due to temperature fluctuations, in particular due to repeated heating and cooling of the connection element and the electrical line, and to ensure a permanently reliable mechanical and electrical connection.
  • the depressions in the crimping section are formed by a cutting, milling, pressing or knurling process.
  • the recesses are created by having material of the crimping section, i. Material of the connection element itself, is removed or displaced.
  • Protrusions lying between adjacent recesses may, for example, have a substantially pyramidal or truncated pyramidal shape.
  • the crimping portion of the terminal member comprises a plating of a metal-containing material having at least one metal other than aluminum and copper.
  • the cladding contains neither aluminum nor copper.

  • the plating may, for example, comprise a tin material, since tin is suitable for achieving particularly low contact resistances to aluminum.
  • the crimping portion of the terminal member is provided with a seal sealing the crimping portion.
  • the seal may be designed such that it seals the crimp section airtight and / or watertight against the surroundings of the crimp section. Such a seal prevents corrosion of the boundary between the terminal and the electric wire, thus contributing to the long-term reliability of the manufactured joint.
  • the seal may be formed of a plastic-containing material and include, for example, a urethane-based thermoplastic elastomer, a polyamide, a polyvinyl chloride, a polyurethane, or a butyl rubber material.
  • the seal encloses both the crimping portion of the terminal member and an end portion of an insulation sheath of the electric wire.
  • the seal may be applied to the crimping section by an injection molding process, a casting process, or a foaming process.
  • the seal can also be applied by a shrink tube is pushed onto the line and the connection element and shrunk while supplying heat to the connection element and the line.
