Definitions

  • the invention relates to a method for producing an electrical connection between an electrical conductor comprising several individual wires and a contact element, the electrical conductor being arranged in a contact section of the contact element and subsequently the contact section and the electrical conductor being pressed together so that the contact section is the electrical conductor encompasses.
  • the invention further relates to a corresponding device for establishing an electrical connection and a unit composed of an electrical conductor comprising several individual wires and a contact element.
  • the contact element is formed, for example, by a cable lug, such as a crimp cable lug, or a cable sleeve, such as a crimp sleeve.
  • connection methods for electrically connecting an electrical cable to a contact element in which a cable crimping section which is provided on the contact element is brought into press contact with an electrical conductor of the electrical cable.
  • a cable crimping section which is provided on the contact element is brought into press contact with an electrical conductor of the electrical cable.
  • the conductor of the electrical cable is made up of a plurality of individual wires, the conductor wires located on the outer circumference are brought into direct contact with the contact element and power conduction is easy to achieve for them.
  • the individual wires that are arranged in the center of the conductor can be connected to the Contact element can only be brought into conductive contact via the individual wires that are located on the outer circumference.
  • DE 10358153 A1 proposed to weld the individual wires to one another and to the contact element by means of a laser in addition to crimping. It is provided there that several areas of the conductor are welded one after the other and overlapping. During the first welding step, rapid heating takes place through the application of the laser beam and an explosive distribution of material within the conductor. A subsequent welded area covers the first welded area and uses the resulting increased temperature condition, in that there is no rapid heating by the laser beam during the second and subsequent welding steps. The material gradually melts so that explosive spreading can be prevented.
  • the disadvantage of this method is that explosive distribution can still occur in the first welding step.
  • the starting point for this is a method for establishing an electrical connection between a number of individual wires comprehensive electrical conductor and a contact element, wherein the electrical conductor is arranged in a contact section of the contact element and subsequently the contact section and the electrical conductor are pressed together so that the contact section engages around the electrical conductor.
  • the contact section by means of a laser irradiation of the contact section at least two elongated welded connections are made between the contact section and the electrical conductor, the elongated welded connections each extending from an irradiated area of the contact section at least in sections into the electrical conductor.
  • the energy input is reduced compared to conventional welding processes because the material should not be melted between the elongated welded joints according to the invention.
  • Elongated welded connections according to the present invention have a greater extent in their longitudinal direction, that is to say in the direction of irradiation, than in the width direction.
  • the length is preferably a multiple of the average width or its diameter, in particular the elongated welded connections can be rod-shaped, that is to say have an approximately constant diameter over their length.
  • Such elongated, in particular rod-shaped, welded connections can be produced by deep laser welding, where high beam intensities in the melt in the radiation direction form a vapor capillary deep into the workpiece. The material is thereby too melted in depth, the melting zone is usually more deep than wide.
  • the irradiated area is generally visible as an approximately round area on the surface of the contact area, corresponding to the diameter of the laser beam and the material of the contact area melted all around.
  • One embodiment variant of the invention provides that the laser irradiation is carried out in such a way that the elongated welded connection extends in the direction of irradiation through the entire cross section of the pressed electrical conductor.
  • the elongated welded connections should therefore best extend in their longitudinal direction from the irradiated area of the contact section through the conductor to that area of the contact section guided around the conductor which is opposite the irradiated area. Then the individual wires captured by this welded connection would even be connected to the contact section at two points.
  • One embodiment variant of the invention provides that several elongated welded connections, preferably all of them, are produced one after the other by the same source of laser irradiation.
  • a source i.e. a laser
  • appropriate optical deflections e.g. mirrors, etc.
  • One embodiment variant of the invention provides that several elongated welded connections are produced in irradiated areas that are regularly spaced from one another.
  • the irradiated areas usually visible as small, approximately circular points on the surface of the contact area, are thus arranged at a distance from one another on the surface of the contact area.
  • the irradiated areas can be arranged on the surface of the contact area according to a grid, for example. The fact that the individual wires are usually also twisted and that their position in the conductor cross-section change over their length also contributes to the contacting of all individual wires.
  • one irradiated area is offset from another irradiated area normal to the longitudinal direction of the individual wires. This ensures that not only one and the same individual wire is always contacted by different elongated welded connections that follow one another in the longitudinal direction of the individual wires and that other adjacent individual wires are not.
  • the degree of compression of the individual wires in a longitudinal region of the contact element in which there are no irradiated regions is less than in FIG a longitudinal area of the contact element where irradiated areas are located.
  • the degree of crimping indicates the ratio of conductor cross-section after crimping (or crimping) to conductor cross-section before crimping (or crimping).
  • a compression rate of 100% means that the conductor cross-section has not been reduced at all by the compression (or crimping), but has remained the same.
  • a compression ratio of 80% means that the conductor cross-section has been reduced to 80% of the original conductor cross-section as a result of the compression (or crimping).
  • the contact section is divided into two longitudinal areas transversely to the longitudinal direction of the individual wires.
  • the conductor In one longitudinal area the conductor is only pressed, in the other longitudinal area the conductor is pressed and additionally irradiated with the laser according to the invention.
  • the longitudinal area where the laser is also irradiated, it is advantageous if there are as many spaces as possible between the individual wires, i.e. an open rope structure is ensured, which acts as a ventilation channel when a melt pressure builds up during the laser welding process.
  • the different degree of compression is produced by a compression tool with a stepped support surface.
  • the length of the two Each step corresponds to a longitudinal section of the contact section.
  • the different heights of the support surface relative to the contact section of the contact element have the effect that the conductor is compressed to different degrees in the two longitudinal sections of the contact element.
  • Another possibility for producing a different degree of compression is that the different degree of compression is produced by a contact section with cable lug claws of different lengths in the transverse direction. That longitudinal section, which is to be pressed together more, then has longer cable lug claws, i.e. more material that is pressed towards the conductor during pressing. In this way, a different height or compression of the conductor can be achieved even with a flat contact surface of the pressing tool.
  • the degree of compression of the individual wires in a longitudinal area of the contact element where the irradiated areas are located is greater than 70%.
  • the laser irradiation takes place in the tool in which the pressing takes place.
  • the position of the pressed electrical conductor is not changed between pressing and laser irradiation.
  • the pressed electrical conductor remains in the tool after pressing and is also welded there with the laser.
  • an elongated welded connection takes less than 50 ms, in particular less than 40 ms, e.g. around 30 ms.
  • the contact section is provided with a nickel coating, at least in the area where it touches the electrical conductor.
  • the nickel layer provides protection against corrosion between the conductor and the contact section and, on the other hand, increases the energy absorption during laser welding.
  • a device for performing the method according to the invention comprises a pressing tool with which the electrical conductor arranged in a contact section of the contact element can be pressed with the contact element, so that the contact section encompasses the electrical conductor, and is characterized in that a device for laser irradiation is provided, which is designed to produce at least two elongated welded connections between the contact section and the electrical conductor, the elongated welded connections each extending in an irradiation direction from an irradiated area of the contact section extend at least in sections into the electrical conductor.
  • the device can be designed such that the position of the pressed electrical conductor is not changed between pressing and laser irradiation.
  • the invention also comprises a unit produced by the method according to the invention or with the device according to the invention from an electrical conductor comprising several individual wires and a contact element, the electrical conductor being arranged in a contact section of the contact element and the contact section and the electrical conductor are pressed together so that the contact section engages around the electrical conductor and there is an electrical connection between the electrical conductor and the contact element.
  • the unit is characterized in that there are at least two elongated welded connections spaced apart from one another between the contact section and the electrical conductor, the elongated welded connections each extending in an irradiation direction from an irradiated area of the contact section into the electrical conductor at least in sections.
  • the invention can be used to produce a so-called B crimp form or heart crimp form, as is known from the prior art.
  • the invention can of course also be used for other types of crimp form or compression form.
  • the invention makes it possible in particular to use individual wires made of aluminum or an aluminum alloy.
  • the use of aluminum for the individual wires leads to the formation of an oxide layer on the surface of the individual wires and thus no stable resistance ratios over the service life of the conductor.
  • the elongate welded connections according to the invention produce a material connection and thus electrical contact between the individual wires and the contact section of the contact element, which contact does not oxidize and therefore guarantees constant resistance ratios.
  • the individual wires made of aluminum or an aluminum alloy are advantageously pressed with a contact section or a contact element (for example crimp cable lug, crimp sleeve) made of copper or a copper alloy, for example bronze, brass.
