Definitions

  • the present invention relates to a device and a method for crimping connecting elements with electrical conductors according to the independent claims.
  • Crimping is a joining process in which a stripped cable is connected to a connecting element.
  • the stripped cable can then be connected to other electrical or electronic components through the connecting element.
  • a cable is inserted into the connection element and the connection element is usually plastically deformed.
  • the connecting element is pressed against the cable or the electrical conductors of the cable as a result of the plastic deformation.
  • the connection element encloses a stripped, i.e. bare, cable part (core crimp) and the cable insulation (insulation crimp).
  • the wire crimp is used for the electrical connection, the insulation crimp for strain relief and fixing of the insulation. This enclosure allows electrical energy to be transmitted from the cable to the connecting element and further.

  • a crimping process and an ultrasonic welding process are carried out in a single operation. This is done by designing an upper embossing die as the sonotrode end of an ultrasonic welding device.

  • the sonotrode head (3.1) has at least one welding surface (3.4) on the circumference with respect to the torsion axis (B).
  • an anvil (18) with a counter/compacting surface (18.1) which can be arranged in a fixed position opposite the welding surface (3.4) of the sonotrode (3).
  • the welding surface (3.4) and the compacting surface (18.1) delimit a compression space (8) provided for receiving parts to be welded in a direction perpendicular to the torsion axis (B).
  • the sonotrode (3) is designed and coupled to the vibration generator (9) in such a way that the entire sonotrode (3) can be excited to perform a torsional vibration with a negligibly small proportion of longitudinal vibrations.
  • JP 2006-147223 A Furthermore deals JP 2006-147223 A with the provision of a shielded wire with a terminal and a manufacturing method having excellent wire fastening strength and electrical connection with restricted rotation of the terminal when an outer conductor terminal is crimped in overlap with the shielded wire.

  • Another object of the invention is to improve the strength of a crimp connection.
  • a further object of the invention is to improve the fatigue strength of a crimped connection and to improve chemical resistance of the crimped connection. Another object of the invention is to increase the electrical conductivity of a crimped connection.

  • the drive arrangement for moving the ram is connected to the ram.
  • the anvils are vibrationally decoupled from each other.
  • Each of the anvils has a receiving surface for crimping the fastener.
  • the device thus has two receiving surfaces, a core crimping area and an insulation crimping area, the areas each being part of one of the at least two anvils.
  • At least one of the anvils is preferably connected to the machine frame.
  • the working space is located between the punch and at least the first anvil and can be opened and closed by a relative movement between the punch and at least the first anvil.

  • a machine frame is understood here as a frame to which machine parts can be attached.
  • machine frames are housings, frames or other devices such as presses that are suitable for supporting parts of the machine.
  • a punch is a part capable of deforming another part.
  • the deformation can be done by the stamp exerting pressure on the part to be deformed.
  • the stamp is held, for example, in a crimping stamp receiving device, such as a moving part of a press.
  • a punch moves towards an anvil.
  • the anvil is in a fixed position.

Furthermore, the introduction of ultrasound can break up an oxide layer on the edge of a conductor onto which the connection element is crimped. In particular, individual conductors of stranded conductors are connected to one another by the ultrasound. Another advantage is that less force has to be applied via the punch. Another advantage is that crimping process monitoring is improved.
  • Crimping and ultrasonic welding can be performed simultaneously with just one device.
  • Crimp connections that are made with such a device have a special quality because they are mechanically resilient and electrically conductive.
  • the device is suitable for crimping a plurality of strands with a connecting element.

With the double stops, two aluminum strands (aluminium/aluminium), two copper strands (copper/copper) or a mixture (copper/aluminium) can be connected to the connecting element.
  • the double attacks can be carried out side by side and one above the other.
  • connection element is crimped onto an insulation of a conductor and another part of the connection element is crimped onto the electrical conductor.

  • Each sonotrode can very particularly preferably be releasably connected to one or more of the anvils. Alternatively, only individual sonotrodes can be detachably connected to one or more of the anvils.
  • At least one of the anvils can be replaced. If, for example, the mounting surface of an anvil wears out, only this anvil has to be replaced and the sonotrode can continue to be used.
  • the sonotrode at least partially forms at least one of the anvils.
  • the sonotrode is in contact with at least one of the anvils, but without being permanently connected to this anvil. In this embodiment, replacing this anvil is particularly easy.

  • At least part of at least one of the anvils is vibrationally decoupled from the machine frame, and this anvil cannot be moved relative to the machine frame during the process.
  • This anvil is preferably immovable relative to the machine frame.
  • vibrationally decoupled bearing of this anvil is a zero point bearing with flanges.
  • Immovable is intended to mean here that an oscillation, in particular an ultrasonic oscillation, is permitted, but no other translational or rotational movements.
  • At least the first working surface is curved such that a contact area between the punch and at least one of the anvils is minimized.
  • the stamp can be held more stably and is more resistant to the ultrasonic vibrations and therefore more durable.
  • the frequency can preferably be adapted to the duration of the closing process.
  • a high frequency can be used for short closing movements. As a result, a sufficient number of oscillations is nevertheless introduced.
  • the sonotrode particularly preferably oscillates at a frequency of greater than or equal to 20 kHz.
  • the sonotrode oscillates at 30 kHz or at 35 kHz.
  • the device can also be used for compressing a stranded wire, in particular a copper or aluminum stranded wire.

  • Ultrasound is applied to the receiving surface of the first by means of a sonotrode Anvil introduced during and / or after a crimping process.
  • the working space is preferably formed by a recess in the punch and the first anvil.
  • Such a method has the advantage that the sonotrode does not have to be moved during crimping. Another advantage is that crimping and ultrasonic welding can be carried out simultaneously in just one processing step in a single device.
  • the introduction of the ultrasound through the first anvil allows for more efficient introduction of the ultrasonic vibrations since the first anvil is in continuous contact with the fastener over a larger area during crimping. As a result, shorter process times can be achieved than with separate ultrasonic welding and crimping and/or more energy can be introduced into the connection part.
  • Another advantage is that the vibrations can be introduced more directly into the individual conductors of a cable.
  • ultrasound is also introduced into the receiving surface by means of the sonotrode before the crimping process.
  • the stamp is not subjected to ultrasound. As a result, there is less ultrasonic stress on the stamp and wear on the stamp is reduced.

  • the ultrasound can be applied permanently or in pulses.
  • a connection between an electrical conductor which does not per se belong to the invention can be produced by a method according to the invention.
  • Crimp connections that are made using such a process are of a particularly high quality because they can withstand mechanical loads and are more electrically conductive.
  • individual conductors of stranded conductors are connected to one another by the ultrasound and an oxide layer is at least partially rubbed away.
  • the individual strands are cold-welded by the applied pressure and the applied ultrasound. The vibrations introduced promote the connection process, reduce the overall force required and at the same time rub away any oxide layers better than in the conventional crimping process.
  • a further aspect of the present disclosure which does not per se belong to the invention, relates to an anvil for an ultrasonic crimping process.
  • the anvil has a fastener receiving surface and an interface.
  • the anvil can be detachably connected to a sonotrode.
