Definitions
- the present invention relates to a device and a method for crimping fasteners and a crimp according to the preamble of the independent claims.
- Crimping is a joining process in which a stripped cable is connected to a connector. By means of the connecting element, the stripped cable can then be connected to further electrical or electronic components.
- crimping a cable is inserted into the connecting element and the connecting element is usually plastically deformed. Due to the plastic deformation, the connecting element is pressed against the cable or the electrical conductors of the cable.
- the connecting element encloses a stripped, al ⁇ so bare, line part (core crimp) and the line insulation (insulation crimp).
- the core crimp is used for the electrical connection, the insulation crimp of the strain relief and fixation of the insulation.

- the anvil is preferably connected to the machine frame.
- a sonotrode is understood here to mean an arrangement which is preferably designed in a frequency of 15-50 kHz swing.
- the sonotrode can oscillate torsionally, linearly or longitudinally.
- the device according to the invention has the advantage that the sonotrode can be integrated particularly easily into a device for crimping. There are only a few design changes neces ⁇ dig to integrate the sonotrode in the device. Furthermore, the introduction of ultrasound can break up an oxide layer on the edge of a conductor onto which the connecting 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 over the punch. Another advantage is that crimp process monitoring is improved.
- Crimp connections which are produced with such a device, have a special quality, since they are mechanically loadable and more electrically conductive.
- the device is suitable for crimping a plurality of strands with a connecting element.

- the anvil is up on the horn shrinkable.
- the anvil can be connected by means of a thread or a plug connection to the sonotrode.
- each sonotrode is releasably connectable with one or more anvils.

- the receiving surface is subjected to torsional vibrations about an axis perpendicular to the receiving surface.
- the receiving surface is ge ⁇ curved and acted upon with vibrations about an axis along a direction of movement of the punch.
- Torsional ultrasonic welding has the advantage that no embrittlement of the connecting element arise. Furthermore, the ultrasound energy can be introduced particularly efficiently.

- the receiving surface can be acted upon by longitudinal oscillations along an axis parallel to the receiving surface.
- the longitu ⁇ dinalen vibrations oscillate along a longitudinal axis of the conductor or perpendicular to the longitudinal axis of the conductor.

- the receiving surface can be subjected to longitudinal oscillations parallel to a direction of movement of the stamp.
- the anvil is not movable relative to the machine frame.
- An example of a vibrationally decoupled storage of the anvil is a zero point bearing with flanges.

- the stamp can be kept more stable and is more resistant to the ultrasonic vibrations and therefore more durable.
- the frequency can be adapted to the duration of the closing process.
- the duration of the closing process can be short in time
- Closing a high frequency can be used. As a result, nevertheless a sufficient number of vibrations is introduced.
- the crimping process force is applied over a short time (eg approx. 200ms).
- ultrasound can be effec- tiver be introduced.
- the sonotrode vibrates at 30 kHz or 35 kHz.
- the device can also be used to compact one
- Litz in particular a copper or aluminum strand can be used.
- Another aspect of the present invention relates to a method for producing a connection between an electrical conductor, preferably a copper or aluminum conductor, and a connecting element.
- a connector is inserted into an open working space defined by an anvil and a movable punch.
- One end of an electrical conductor is inserted into the connecting element.
- the working space is closed by the movable punch.
- At least one working ⁇ surface of the stamp and at least one receiving surface of the bosses on the connecting member ⁇ deform plastically in particular during closure, so that a positive contact between the electrical conductor and the connecting element is formed.
- Ultrasound is introduced by means of a sonot ⁇ rode in the receiving surface of the anvil during and / or after a crimping process.
- the working space is formed by a recess in the punch and the anvil.
- Such a method has the advantage that the sonotrode does not have to be moved during crimping. Another advantage is that with only one processing step in a single device can be simultaneously crimped and ultrasonically welded.
- the introduction of the ultrasound through the anvil allows a more efficient initiation of the ultrasonic vibrations, since the anvil during crimping over a larger area continuous lent to the connecting element in contact. As a result, shorter process times than with separate ultrasonic welding and crimping can be achieved and / or more energy can be introduced into the connecting part.
- a further advantage is that the vibrations can be introduced more directly into individual conductors of a cable.
- ultrasound is ⁇ passes into the receiving surface by means of the sonotrode even before the crimping process.
- the stamp is not subjected to ultrasound. As a result, a load of the stamp by ultrasound is lower and wear on the stamp is reduced.
- the introduction of ultrasound breaks up an oxide layer on the electrical conductor.
- the breaking up of the oxide layer improves an electrical conduction between the connection element and the electrical conductor.
- aluminum conductors have an outer oxide layer, which reduces the conductivity.
- the movable punch has a first working surface and the anvil has a first receiving surface.
- a first portion of a connecting element with a preferably electrically lei ⁇ border part of the electrical conductor by the first receiving ⁇ surface and the first work surface is connected.
- the mobile one Stamp has a second work surface and the anvil on a second receiving surface.
- a second portion of a connecting element is connected to the electrical conductor, preferably with an insulation of the conductor, through the second receiving surface and the second working surface.

- the ultrasound is at least, more preferably only, transferred at the time of maximum adhesion of the punch an ultrasonic pulse in the connecting element.
- the ultrasound is transmitted most effec ⁇ tively in the connecting element and / or the stranded wire. It is also conceivable to initiate the ultrasound permanently, ie before, during and after the crimping.
- the ultrasound may permanently or pulsed introduced ⁇ to.
- Another aspect of the invention relates to a crimp connection made by a method of making a connection between an electrical conductor according to any one of the claims.
- Crimp connections which are produced by such method have made a special quality, as they are mechanically be ⁇ lastbar and electrically conductive.
- individual conductors of stranded conductors are connected to one another by the ultrasound and an oxide layer is at least partially wiped.
- the individual strands are cold-welded by the introduced pressing force and the introduced ultrasound. The induced vibrations promote the process of connection, reduce the required force as a whole and at the same time rub off possible oxide layers better than in the conventional crimping process.
- Another aspect of the present invention relates to an anvil for an ultrasonic crimping process.
- the anvil has a receiving surface for a connecting element and an interface.
- the anvil can be detachably connected to a sonotrode.
