Definitions
- the invention relates to a device and a method for the densely connecting electrical conductors and corresponding uses.
- EP 0 143 936 B2 discloses a device for connecting or compressing electrical conductors in the form of strands, which has a sonotrode generating sound vibrations, with this associated counterelectrode which serves as an anvil and can be moved relatively thereto, and a compression chamber intended for receiving the conductors, are formed by the opposite boundary surfaces of at least one surface of the sonotrode and the anvil each, the cross-section of the compression space being adjustable in a first direction by changing the distance between the surface of the sonotrode and anvil, the remaining opposite boundary surfaces being formed by boundary elements, of which at least one delimiting element is displaceable or movable away, to change the cross section of the compression space in a direction perpendicular to the first direction to adjust the compression space to conductors of different cross sections Ippable cheek is.
- a disadvantage of this is the fact that only relatively angular conductor cross sections are obtained with the devices known from the prior art, which are considered disadvantageous for many applications due to the later very cramped installation conditions of the conductors due to the relatively large cross-sectional area requirement. In addition, there is a greater risk of injury due to the often relatively sharp-edged conductor cross-section. From the above, the problem arises of at least partially eliminating or avoiding the disadvantages mentioned above.
- the device according to the invention for the compressive connection of electrical conductors in particular in the form of strands, comprises a sonotrode which produces sound vibrations, at least one counterelectrode associated with the sonotrode and movable relative thereto, and a compression space intended for receiving the conductors, the at least almost orthogonal to the longitudinal axis of the to be connected Conductor-lying cross-section of the compression space during the compression connection is determined only by the inner boundary surfaces of the sonotrode and the counter electrode.
- the inner boundary surfaces during compression form a triangular cross section lying at least almost orthogonally to the longitudinal axis of the conductors to be connected, the counter electrode having two counter electrode parts which can run together and form the triangular cross section in connection with the inner boundary surface of the sonotrode.
- the inner boundary surfaces can be slightly concave.
- the great advantage of this embodiment is the fact that the "welded" conductor structure is surprisingly very homogeneous compared to the usual rectangular cross-sections due to the triangular cross-section after the compacting connection by means of ultrasound exposure and unintentional removal of individual conductors is thus effectively avoided
- the reason is that when the ultrasonic energy is applied due to an energy dissipation in the compacted Conductor material is applied to the edge areas in the usual rectangular cross sections in comparison to the inner areas considerably less and more unevenly, so that there are the frequent unhomogeneous "welds" which are documented until individual conductor strands are detached, which are highly undesirable, in particular To prevent short circuits of closely spaced conductors due to touching individual strands or to reduce the risk of injury when working.
- the sequence of the method according to the invention is as follows: First, the conductors to be connected are accommodated in a compression space which is still at least half open, then the compression space is closed with respect to the cross section which is at least almost orthogonal to the longitudinal axis of the conductors to be connected (the term "closed” according to the invention to that effect It is to be understood that at least no individual strand can jam and is therefore in the micrometer range; consequently, at least one conductor is to be dealt with with a previously defined distance in relation to the conductor goods to be connected) the cross section is reduced until the conductor is mechanically compressed, Subsequently, the conductors are subjected to sound vibrations connecting via a sonotrode, in order finally to release the conductively connected conductors, the closing of the compression space by means of moving the two counter-electrode parts together and / or by means of elsewhere, sliding at least one counter-electrode part on the sonotrode at a defined distance, reducing the cross-section by rubbing the
- the two counter-electrode parts touch during the compressive connection, while the counter-electrode parts are arranged at a defined distance from the sonotrode that is suitable for the respective purpose.
- This gap dimensions i.e. the respective distances
- the surfaces sliding against one another is generally approximately 10 ⁇ m.
- the cross section is advantageously an equilateral triangle, since it is imperative in the case of generally planar and straight inner boundary surfaces that the angles between the inner boundary surfaces be 60 ° in order to prevent jamming sliding.
- At least one inner boundary surface from the group of sonotrode and counter electrode parts, but in particular all inner boundary surfaces, has a conductor run-up surface protruding from the plane of the inner boundary surface in order to prevent jamming between the counter electrode parts and the electrode when the respective conductor is compressed. Avoid sonotrode. For a particularly safe avoidance of the jamming mentioned above, it is particularly advantageous if at least one, in particular all, of the conductor run-up surface is concave with respect to its surface.
- the counter electrode parts and / or the sonotrode consist of a steel from the group of cold work steels.
- the cold work steels are those from the group with the following composition:
- the counter electrode parts are driven by cylinders, which are in particular pneumatic cylinders (cylinders which are driven in particular by compressed air).
- cylinders which are in particular pneumatic cylinders (cylinders which are driven in particular by compressed air).
- at least one cylinder is advantageously a tandem cylinder, since in this way a gradual adaptation of the force to be applied of the sonotrode or of the respective counter-electrode part to the conductor to be compressed can be accomplished.
- the term “tandem cylinder” is to be understood as a cylinder in which at least two pistons are arranged one behind the other on the same piston rod.
- both counter-electrode parts can be moved via a single drive, the movement sequences being synchronized via a positive connection, in particular if the positive connection is a sliding element , on which the one counter-electrode part is rigidly attached and the other counter-electrode part is guided via a guide element which is fixedly connected to the sliding element and engages in a guide recess of the other counter-electrode part, at least the other counter-electrode part being movably supported in a positive guide.
- the positive connection is a sliding element , on which the one counter-electrode part is rigidly attached and the other counter-electrode part is guided via a guide element which is fixedly connected to the sliding element and engages in a guide recess of the other counter-electrode part, at least the other counter-electrode part being movably supported in a positive guide.
- the forces usually to be applied for compressing the conductors are in the order of magnitude of approximately 1000 to several thousand Newtons, the energy density of the ultrasonic waves to be applied, which are to be located in terms of their frequency in the range of approximately 20-40 kHz, in the range of about 1 - 20 J / mm 3 (J corresponds to Ws).
- Figure la - ld - a sketchy cross-sectional representation of an embodiment of the device according to the invention in different stages of the method according to the invention
- Figure 2a - 2c - a sketchy cross-sectional representation of a further embodiment of the device according to the invention in different stages of the method according to the invention.
- a sonotrode 1 and a two-part counter electrode 2 3 can be seen in FIG. 1 a, which form a semi-open triangular cross section 4.
- the sonotrodel has a conductor contact surface 5 and the counter electrode 2, 3 each has a conductor contact surface 5.5. Furthermore, the sonotrode 1 and the counter electrode 2, 3 have inner boundary surfaces 6, 6, 6.
- the left part of the counter electrode 2 is moved by means of a pneumatic cylinder (not shown) onto the inner boundary surface 6 of the right part of the counter electrode 2 (the two counter electrode parts thus touch) that the triangular compression chamber 4 is closed (see Figure lb).
- the right part of the counter electrode 2 then moves to the left, while at the same time the left part of the counter electrode 3 is moved obliquely to the bottom left, as a result of which the compression space 4 is reduced (see FIG. 1 c). .
- FIG. 2a shows a sonotrode 1 and a counterelectrode 2, 3 consisting of two parts, which form a semi-open triangular cross section 4.
- the sonotrodel points a conductor run-up surface 5 and the counter electrode 2, 3 each have a conductor run-up surface 5.5.
- the sonotrode 1 and the counter electrode 2, 3 have inner boundary surfaces 6, 6, 6.
- the two counter electrode parts 2, 3 are positively connected via a sliding element 7 to which the right counter electrode part 3 is rigidly attached.
- the left counterelectrode part 2 is guided in the form of a pin via a guide element 9 which is fixedly connected to the left counterelectrode part 2 and engages in a guide recess 8 of the sliding element 7, the left counterelectrode part 2 being movably mounted in a positive guide 10.
- the right counter-electrode part 3 is moved onto the inner boundary surface 6 of the left counter-electrode part 2 by means of a stepper motor (the two counter-electrode parts thus touch), so that the triangular compression space 4 is closed ( see Figure 2b).
- the right counter-electrode part 3 then moves to the left, while at the same time the left counter-electrode part 2 is moved obliquely to the bottom left via the sliding element 7 moving to the left and the guide pin 9 engaging in the guide recess 8 of the sliding element 7, as a result of which the compression space 4 is reduced ( see Figure lc). It is therefore a special synchronization of the movement sequences of the two counter electrode parts 2 and 3 via only one drive.
- ultrasound energy is applied to the conductors to be connected via the sonotrode 1, in order to then open the compression chamber 4 again by moving the right counter-electrode part 2 to the right.
