Definitions
- the present invention relates to a conductor connection comprising a plurality of conductors attached to one another.
- the conductors are, for example, a stranded wire that is connected to a rigid connection element, for example a connection pin.
- Such conductors are used, for example, in electrical components, in particular in inductive components.
- conductors are electrically connected to one another by soldering or welding. Before the electrical connection is established, the conductors are mechanically fixed to one another. When connecting a litz wire to a connection pin, the litz wire is wrapped around the connection pin, for example. The fastening by winding often does not provide sufficient mechanical stability for the subsequent electrical connection. An additional mechanical fastening of the wires to one another is often time-consuming and costly.
- the pamphlet GB 816 499 A describes a tubular connector for connecting a cable to a feed line. The cable and the supply line are inserted through openings in the connector.
- the pamphlet WO 2013/039124 A1 describes a connection of a coaxial cable to a cable lug using a crimp element.
- a conductor connection according to claim 1 is specified.
- the conductor connection is, for example, part of a component.
- the component is an inductance.
- the connector has one or more openings.
- the connecting piece has two openings.
- the conductors each extend into the connector through one of the openings.
- the conductors are attached to one another by means of the connecting piece.
- the connector creates a press connection between the conductors.
- Such a connection can also be referred to as a crimp connection.
- the connecting piece is in particular a so-called “splice crimp”.
- the connecting piece is designed as a metallic piece of tape bent around the conductor. To produce the conductor connection and the shape of the connecting piece, the metallic piece of tape is bent around the conductors that are arranged next to one another. The piece of tape is pressed against the ladder.
- the connecting piece receives its shape, in particular a sleeve shape, only when it is formed around the conductor.
- the piece of tape is, for example, made flat before the bending process.
- lateral areas of the piece of tape overlap after the forming process. The overlapping of the lateral areas allows such a connector to be distinguished from a prefabricated sleeve such as a cable lug.
- the connecting piece has a wall, the distance between the wall increasing from a longitudinal axis of the connecting piece towards the opening.
- the increasing distance between the wall and the opening is present at least in a longitudinal section of the connecting piece.
- the increasing spacing of the wall can also be designed to be circumferential.
- a diameter and / or cross section of the connecting piece also increases towards the opening.
- the increasing diameter is present at least in a longitudinal section of the connecting piece.
- the connecting piece can also have a circumferential increasing diameter.
- the connecting piece has, for example, an opening area which opens into the opening, the distance between the wall and a longitudinal axis increasing in the opening area.
- the connecting piece has, for example, a flat area in which the distance between the wall and the longitudinal axis is constant. In particular, the diameter and / or cross section is constant in the flat area.
- the connecting piece has a concave shape, for example in the area of the opening, in particular in the opening area.
- a contour line of the connecting piece is concave.
- the course of the wall of the connecting piece in a longitudinal section is referred to as the contour line.
- the connecting piece has a trumpet shape in the region of the opening.
- the connecting piece can have a cylindrical shape, for example in the area of the opening, in particular in the opening area.
- a contour line runs linearly.
- Such a shape of the connecting piece in the area of the opening can reduce the mechanical and thermomechanical stress on the conductors. This is especially the case when the shape of the connector is adapted to the course of at least one of the conductors in the area of the opening. In this way, friction between the connection piece and the conductor or a notch in the conductor due to the connection piece and thus mechanical damage can be avoided.
- At least one of the conductors leads away from the longitudinal axis of the connecting piece in the region of the opening.
- the conductor runs at an angle to the longitudinal axis in the area of the opening.
- the distance between the conductor and a longitudinal axis of the connecting piece in the area of the opening can be greater than or equal to the distance between the wall and the longitudinal axis in the flat area. In the case of a completely flat connection piece, there would be a risk of mechanical damage to the conductor by the connection piece.
- At least one of the conductors has mechanical flexibility.
- at least one of the conductors is designed as a wire, in particular as a stranded wire.
- the stranded wire leads away from the longitudinal axis of the connecting piece in the area of the opening, for example.
- connection element For example, at least one of the conductors is designed as a rigid connection element.
- it can be a connection pin.
- the connection element also runs parallel to the longitudinal axis of the connecting piece in the region of the opening, for example.
- one of the conductors is wound around another of the conductors in the region of the connecting piece.
- the Winding enables a defined arrangement of the conductors to one another during the attachment of the connecting piece.
- the connecting piece connects a stranded wire with a rigid connection element, in particular with a connection pin.
- the stranded wire can be wound around the connection pin in the area of the conductor connection.
- the conductors each have a free end.
- the respective conductor is, for example, cut off at the free end.
- the free ends protrude, for example, from one of the openings or are arranged within the connecting piece.
- the free ends are arranged in the area of the same opening. In such an embodiment, the free ends can also be soldered to one another particularly well.
- Each of the conductors is, for example, part of a component or is connected to a component.
- the conductors can be connected to a functional part of a component. This can be an inductance, for example.
- the conductors extend, for example, coming from the component or functional part into one of the openings in the connecting piece.
- the conductors can extend into the same opening or into different openings.
- the connecting piece has two openings, the spacing of the wall from the longitudinal axis increasing towards both openings.
- the diameter and / or cross section of the connecting piece can increase towards both openings.
- the connecting piece can be formed as described above in the region of each of the openings be.
- the connecting piece can have a cylindrical shape or a trumpet shape in the area of both openings.
- the connecting piece has, for example, two opening areas which each open into one of the openings.
- a flat area can be formed between the opening areas. In the opening areas, the distance of the wall from the longitudinal axis to the opening increases. In the flat area, the distance between the wall is constant.
- the opening areas can be designed the same or different.
- Such a shape of the connecting piece is, for example, particularly favorable for connecting conductors in which at least one of the conductors leads away from the longitudinal axis in the area of each opening.
- connection of the conductors is made only by the connector.
- the conductors can also be soldered to one another.
- the conductors can also be welded to one another. For example, a mechanical fastening of the conductors to one another is made by the connecting piece and the electrical connection is made by additional soldering or welding. Soldering or welding can also strengthen the mechanical connection.
- a component with the previously described conductor connection is specified. It is in particular an electrical component, such as. B. an inductor.
- the component has, for example, a functional part from which at least one of the conductors leads into an opening in the connecting piece. This is, for example, the opening towards which the distance between the wall and the longitudinal axis increases.
- the conductors can, for example, both come from the functional part and extend into the same opening.
- a flat piece of metallic tape is provided.
- the piece of tape is separated from a longer tape, for example.
- Two conductors arranged next to one another are provided. For example, one is the conductor is wrapped around the other conductor at least in some areas. The conductors can, for example, only rest against one another.
- the piece of tape is bent around the two conductors so that the described conductor connection and / or the connecting piece is obtained.
- a press connection of the conductors is obtained by the connecting piece.
- the conductors are then cut off, for example in the area of one of the openings.
- the conductor connection can have sufficient mechanical stability so that no further connection technology is required.
- an additional electrical and / or mechanical connection can be made after the press connection has been established.
- Such an additional connection is made, for example, by soldering or welding.
- the additional connection is made, for example, in the area of the severed ends of the conductors.
- Figure 1 shows a conductor connection 100 comprising a connector 1 for connecting a plurality of electrical conductors 2, 3.
- the connector 1 is around the conductors 2, 3 bent around and creates a press connection of the conductors 2, 3.
- the conductor connection 100 is part of an electrical component 5.
- One or both of the conductors 2, 3 lead from a functional part 4 of the electrical component 5 to the connector 1.
- the functional part 4 can be, for example, an electrical functional part of a component, for example a Inductance, or around a mechanical functional part, for example around a carrier.
- the connecting piece 1 is designed as a metallic band piece 18 which is bent about a longitudinal axis 6.
- the longitudinal axis 6 is a central axis in the longitudinal direction of the connecting piece 1.
- the longitudinal axis 6 can represent an axis of symmetry of the connecting piece 1.
- the longitudinal axis 6 corresponds, for example, to a longitudinal axis of the conductors 2, 3.
- connection piece 1 The conductors 2, 3 are thus mechanically connected to one another by the connection piece 1.
- the connection can have sufficient stability so that no soldering and no other, further connection technology are required.
- the conductors 2, 3 connected to the connecting piece 1 can additionally be connected to one another by soldering and / or welding.
- the connection by means of a connecting piece 1 is easier to establish, for example and more reliable than the connection by means of an additional wire wound around the conductors 2, 3.
- Such a connector 1 is usually referred to as a "splice crimp".
- the connector 1 differs from a prefabricated sleeve into which one or more conductors are inserted.
- the present connection piece 1 receives its sleeve shape only during the deformation around the conductors 2, 3. The conductors 2, 3 are therefore not inserted into the connection piece 1.
- the connecting piece 1 is not formed in one piece with any of the conductors 2, 3.
- the connecting piece 1 has, for example, copper, brass, bronze or other copper alloys as the material.
- the first conductor 2 is, for example, a rigid connection element.
- it is a connection pin, which is also referred to as a pin.
- the second conductor 3 is, for example, a bendable wire, for example a stranded wire.
- the stranded wire can comprise copper.
- the stranded wire has, for example, 2 to 5000 individual wires.
- the second conductor 3 is wound around the first conductor 2 at least in sections, for example.
- the two conductors 2, 3 can also be the same type of conductor.
- more than two conductors 2, 3 can also be connected by the connecting piece 1. For example, several stranded wires and a connection pin are connected to one another.
- the conductors 2, 3 lead, for example, starting from a functional element 4 of the component 5 into the connecting piece 1.
- the conductors 2, 3 each have a free end 9, 10, for example.
- the connecting piece 1 has two openings 7, 8.
- the openings 7, 8 are formed on opposite end faces of the connecting piece 1. At least one of the conductors 2, 3 is led into and / or out of the connecting piece 1 into at least one of the openings 7, 8.
- each conductor 2, 3, starting from the functional element 4 first extends into the first opening 7.
- the conductors 2, 3 extend into the connecting piece 1 from different openings.
- the first conductor 2 coming from the functional element 4 extends into the first opening 7 and the second conductor 3, e.g. starting from a further functional element (not shown), extends through the second opening 8.
- both free ends 9, 10 protrude from the connecting piece 1 through the second opening 8.
- One or both free ends 9, 10 can also lie within the connecting piece 1.
- one or both free ends 9, 10 can protrude from the first opening 7 through which the conductors 2, 3 extend into the connecting piece 1.
- the second conductor 3 extends through the first opening 7 into the connecting piece 1 and is bent over in such a way that its free end 9 protrudes again from the first opening 7.
- the connecting piece 1 has a wall 11 whose distance a from the longitudinal axis 6 in the direction of the first opening 7 increases. Correspondingly, the contour of the wall 11 leads away from the longitudinal axis 6 in the direction of the first opening 7 in the longitudinal section.
- the connecting piece 1 can also have the increasing distance a from the wall 11 circumferentially.
- the diameter D of the connecting piece 1 increases in the direction of the first opening 7.
- the connecting piece 1 has, for example, its largest diameter at the first opening 7.
- the cross section of the connecting piece 1 also increases, for example, in the direction of the first opening 7.
- the connecting piece 1 has, for example, a first opening region 12 in which the contour of the wall 11 leading away from the longitudinal axis 6 is present. Furthermore, the connecting piece 1 has a flat area 13 in which the distance a of the wall 11 from the longitudinal axis 6 is constant.
- the contour of the wall 11 of the connecting piece 1 is adapted to the course of the second conductor 3, for example.
- the opening area 12 is therefore not shaped as an insertion aid, but designed to prevent mechanical damage.
- the distance 1 of the second conductor 3 from the longitudinal axis 6 in the area of the opening 7 increases towards the outside.
- the distance 1 in the area of the opening 7 can be, for example, equal to or greater than the distance between the wall 11 in the flat area 13.
- the functional element 4 has, for example, only a small distance from the connecting piece 1. Thus, there is only a narrow gap between the connecting piece 1 and the functional element 4. For example, the distance d between the functional element 4 and the connecting piece 1 is less than or equal to 1 mm. In this case, the mechanical stress on a conductor 3 leading away from the longitudinal axis is particularly high.
- the adapted contour of the wall 11 of the connecting piece 1 prevents damage. This can, for example, also enable the component 5 to be used at higher temperatures.
- the connecting piece 1 has, for example, an extension along the longitudinal axis 6 of a maximum of 30 mm.
- the extension along the longitudinal axis 6 is at least 1.5 mm, for example.
- the first opening region 12 has, for example, an extension t along the longitudinal axis 6 of 0.15% to 0.5% of the extension of the connecting piece 1.
- the contour of the wall 11 is concave, for example.
- the connecting piece 1 has the shape of a trumpet at least in the area of the opening 7.
- the contour of the wall 11 can also run linearly.
- the contour line of the wall 11 runs at a fixed angle to the longitudinal axis 6.
- the connecting piece 1 has the shape of a cylinder at least in the area of the opening 7.
- the second opening 8 can also have a contour of the wall 11 leading away from the longitudinal axis 6. Furthermore, it can also be provided that both openings 7, 8 have a contour of the wall 11 leading away from the longitudinal axis 6. This is particularly advantageous if conductors protrude from the two openings 7, 8 and extend away from the longitudinal axis 6. Furthermore, when the two openings 7, 8 are formed with a contour of the wall 11 leading away from the longitudinal axis 6, the connecting piece 1 can be designed symmetrically, which simplifies the manufacture of the connecting piece 1 and enables more flexible use.
- the connecting piece 1 has two lateral areas 14, 15 which overlap.
- the areas 14, 15 overlap in a direction perpendicular to the longitudinal axis 6, so that there the second area 15 is arranged above the first area 14.
- the overlap extends, for example, in the longitudinal direction over the entire connecting piece 1.
- a connecting piece 1 with such overlapping areas can easily be distinguished from a preformed sleeve.
- the overlapping areas 14, 15 of the connecting piece 1 are in the present case in close contact with one another. This applies in particular to the flat area 13 of the connecting piece 1. In the opening area 12, the overlapping areas 14, 15 are not always in close contact, as is the case, for example, in FIG Figure 2 you can see.
- Figure 2 shows a connector 1 and two conductors 2, 3 connected thereto in a front view.
- it is a plan view of an end face of the connecting piece 1.
- it is an embodiment similar or identical to the embodiment of FIG Figure 1 .
- the connecting piece 1 has, for example, a contour of the wall 11 leading away from the longitudinal axis 6 in an area 16 in which the second conductor 3 leads into the opening 7. In a further area 17, which is opposite the area 16 as seen from the first conductor 2, for example, the connecting piece 1 can have a different contour.
- the contour of the wall 11 runs parallel to the longitudinal axis 6 there.
- Figures 3 and 4 show the connector 1 and the conductors 2, 3 connected thereto Figure 2 in different perspective views.
- the flexible first conductor 3 is partially wound around the rigid second conductor 2.
- the conductor 3 extends, for example, coming from a functional element 4 into the first opening 7 and out of the second opening 8. Beyond the second opening 8, the first conductor 3 is bent over, for example, and extends through the second opening 8 back into the connector 1.
- the end of the second conductor 3 is arranged in the connection piece 1.
- Figure 5 shows the embodiment of Figures 2 to 4 in a plan view of the opening area 12 of the connecting piece 1.
- the conductors 2, 3 can be seen here within the connecting piece 1.
- the conductors 2, 3 are pressed against one another.
- the flexible conductor 3 is partially deformed due to the compression.
- stranded wires of the flexible conductor 3 are deformed.
- FIG. 11 shows a method step in the production of the conductor connection 100 according to FIG Figures 1 to 5 .
- the connecting piece 1 is bent around the conductors 2, 3 by means of a shaping device 19.
- the conductors 2, 3 to be connected are arranged next to one another.
- the second conductor 3 is wound around the first conductor 2.
- the conductors 2, 3 arranged next to one another are inserted into a holding part 20 of the shaping device 19.
- a piece of metallic tape 18 is provided.
- the piece of tape 18 is, for example, flat at the beginning of the method.
- the piece of tape 18 is separated from a longer tape, for example a roll.
- the piece of tape 18 is inserted into a further holding part 21 of the forming device 19.
- the shaping device 19 has one or more movable shaping parts 22, in particular movable punches.
- the formed parts 22 are moved towards the metal piece 18 and press lateral areas of the metal piece 18 downwards.
- the lateral areas wrap around the conductors 2, 3.
- the formed parts 22 do not extend, for example, along a region 23 of the metal piece 18 from which the opening region 12 with the contour of the wall 11 leading away from the longitudinal axis is formed (see FIG Figure 1 ). In this way, the described contour is formed by the lack of action of the deformed parts 22.
- the deformed parts 22 act on a region 24 from which the flat region 13 is formed (see FIG Figure 1 ).
- the shaping device 19 can have further movable parts for shaping the band piece 18 and for forming the press connection.
- the formed parts 22 can also be guided around the conductors 2, 3.
- the conductors 2, 3 After being connected by the connecting piece 1, the conductors 2, 3 can be cut off on the other side of one of the openings 7, 8, in particular on the other side of the second opening 8. The conductors 2, 3 then have non-insulated ends that are easily accessible for soldering. This simplifies and shortens the soldering process. In addition, solder bridges are avoided.
- connection piece 1 After the connection, there is no additional connection, in particular no soldered or welded connection, so that the conductors 2, 3 are only connected to one another by the connection piece 1.
- Figure 7 branches another embodiment of a conductor connection 100 with a connection piece 1 in a side, schematic view.

Description
Die vorliegende Erfindung betrifft eine Leiterverbindung aufweisend mehrere aneinander befestigte Leiter. Bei den Leitern handelt es sich beispielsweise um einen Litzendraht, der mit einem starren Anschlusselement, beispielsweise einem Anschlusspin, verbunden ist. Derartige Leiter werden beispielsweise bei elektrischen Bauteilen, insbesondere bei induktiven Bauteilen, eingesetzt.The present invention relates to a conductor connection comprising a plurality of conductors attached to one another. The conductors are, for example, a stranded wire that is connected to a rigid connection element, for example a connection pin. Such conductors are used, for example, in electrical components, in particular in inductive components.
Üblicherweise werden derartige Leiter durch Löten oder Schweißen miteinander elektrisch verbunden. Vor der Herstellung der elektrischen Verbindung werden die Leiter mechanisch aneinander fixiert. Bei einer Verbindung eines Litzendrahtes mit einem Anschlusspin wird der Litzendraht beispielsweise um den Anschlusspin gewickelt. Die Befestigung durch Wickeln liefert für die anschließende elektrische Verbindung oftmals keine ausreichende mechanische Stabilität. Eine zusätzliche mechanische Befestigung der Drähte aneinander ist oft zeitaufwändig und kostenintensiv.Usually such conductors are electrically connected to one another by soldering or welding. Before the electrical connection is established, the conductors are mechanically fixed to one another. When connecting a litz wire to a connection pin, the litz wire is wrapped around the connection pin, for example. The fastening by winding often does not provide sufficient mechanical stability for the subsequent electrical connection. An additional mechanical fastening of the wires to one another is often time-consuming and costly.
Die Druckschrift
Es ist eine Aufgabe der vorliegenden Erfindung, eine Leiterverbindung mit verbesserten Eigenschaften anzugeben.It is an object of the present invention to provide a conductor connection with improved properties.
Gemäß einem ersten Aspekt der vorliegenden Erfindung wird eine Leiterverbindung nach Anspruch 1 angegeben. Die Leiterverbindung ist beispielsweise Bestandteil eines Bauteils. Beispielsweise handelt es sich bei dem Bauteil um eine Induktivität.According to a first aspect of the present invention, a conductor connection according to
Das Verbindungsstück weist ein oder mehrere Öffnungen auf.The connector has one or more openings.
Insbesondere weist das Verbindungsstück zwei Öffnungen auf. Die Leiter reichen jeweils durch eine der Öffnungen in das Verbindungsstück hinein. Durch das Verbindungsstück sind die Leiter aneinander befestigt. Das Verbindungsstück stellt eine Pressverbindung der Leiter her. Eine derartige Verbindung kann auch als Crimpverbindung bezeichnet werden.In particular, the connecting piece has two openings. The conductors each extend into the connector through one of the openings. The conductors are attached to one another by means of the connecting piece. The connector creates a press connection between the conductors. Such a connection can also be referred to as a crimp connection.
Bei dem Verbindungsstück handelt es sich insbesondere um einen sogenannten "splice crimp". Dabei ist das Verbindungsstück als ein um die Leiter gebogenes, metallisches Bandstück ausgebildet. Zur Herstellung der Leiterverbindung und der Form des Verbindungsstücks wird das metallische Bandstück um die aneinander angeordneten Leiter herumgebogen. Dabei wird das Bandstück an die Leiter angepresst.The connecting piece is in particular a so-called “splice crimp”. The connecting piece is designed as a metallic piece of tape bent around the conductor. To produce the conductor connection and the shape of the connecting piece, the metallic piece of tape is bent around the conductors that are arranged next to one another. The piece of tape is pressed against the ladder.
Das Verbindungsstück erhält seine Form, insbesondere eine Hülsenform, erst bei der Umformung um die Leiter. Das Bandstück ist vor dem Biegeprozess beispielsweise flach ausgebildet. Erfindungsgemäß überlappen sich nach dem Umformprozess seitliche Bereiche des Bandstücks. Durch die Überlappung der seitlichen Bereiche lässt sich ein derartiges Verbindungsstück von einer vorgefertigten Hülse, wie z.B. einem Kabelschuh, unterscheiden.The connecting piece receives its shape, in particular a sleeve shape, only when it is formed around the conductor. The piece of tape is, for example, made flat before the bending process. According to the invention, lateral areas of the piece of tape overlap after the forming process. The overlapping of the lateral areas allows such a connector to be distinguished from a prefabricated sleeve such as a cable lug.
Das Verbindungsstück weist eine Wandung auf, wobei der Abstand der Wandung von einer Längsachse des Verbindungsstücks zur Öffnung hin zunimmt. Der zunehmende Abstand der Wandung zur Öffnung hin ist wenigstens in einem Längsschnitt des Verbindungsstücks vorhanden. Der zunehmende Abstand der Wandung kann auch umlaufend ausgebildet sein.The connecting piece has a wall, the distance between the wall increasing from a longitudinal axis of the connecting piece towards the opening. The increasing distance between the wall and the opening is present at least in a longitudinal section of the connecting piece. The increasing spacing of the wall can also be designed to be circumferential.
Beispielsweise nimmt auch ein Durchmesser und/oder Querschnitt des Verbindungsstücks zur Öffnung hin zu. Der zunehmende Durchmesser ist zumindest in einem Längsschnitt des Verbindungsstücks vorhanden. Das Verbindungsstück kann auch umlaufend einen zunehmenden Durchmesser aufweisen.For example, a diameter and / or cross section of the connecting piece also increases towards the opening. The increasing diameter is present at least in a longitudinal section of the connecting piece. The connecting piece can also have a circumferential increasing diameter.
Das Verbindungsstück weist beispielsweise einen Öffnungsbereich auf, der in der Öffnung mündet, wobei der Abstand der Wandung von einer Längsachse im Öffnungsbereich zunimmt. Das Verbindungsstück weist beispielsweise einen Flachbereich auf, in dem der Abstand der Wandung von der Längsachse gleichbleibend ist. Insbesondere ist der Durchmesser und/oder Querschnitt im Flachbereich gleichbleibend.The connecting piece has, for example, an opening area which opens into the opening, the distance between the wall and a longitudinal axis increasing in the opening area. The connecting piece has, for example, a flat area in which the distance between the wall and the longitudinal axis is constant. In particular, the diameter and / or cross section is constant in the flat area.
Das Verbindungsstück weist beispielsweise im Bereich der Öffnung, insbesondere im Öffnungsbereich, eine konkave Form auf. Insbesondere verläuft eine Konturlinie des Verbindungsstücks konkav. Als Konturlinie wird der Verlauf der Wandung des Verbindungsstücks in einem Längsschnitt bezeichnet. Beispielsweise weist das Verbindungsstück im Bereich der Öffnung eine Trompetenform auf.The connecting piece has a concave shape, for example in the area of the opening, in particular in the opening area. In particular, a contour line of the connecting piece is concave. The course of the wall of the connecting piece in a longitudinal section is referred to as the contour line. For example, the connecting piece has a trumpet shape in the region of the opening.
Alternativ kann das Verbindungstück beispielsweise im Bereich der Öffnung, insbesondere im Öffnungsbereich, eine zylindrische Form aufweisen. Insbesondere verläuft eine Konturlinie linear.Alternatively, the connecting piece can have a cylindrical shape, for example in the area of the opening, in particular in the opening area. In particular, a contour line runs linearly.
Durch eine derartige Form des Verbindungsstücks im Bereich der Öffnung kann die mechanische und thermomechanische Beanspruchung der Leiter reduziert werden. Dies ist insbesondere dann der Fall, wenn die Form des Verbindungsstücks im Bereich der Öffnung an den Verlauf wenigstens eines der Leiter angepasst ist. Auf diese Weise kann eine Reibung des Verbindungsstücks am Leiter oder eine Einkerbung des Leiters durch das Verbindungsstück und damit eine mechanische Beschädigung vermieden werden.Such a shape of the connecting piece in the area of the opening can reduce the mechanical and thermomechanical stress on the conductors. This is especially the case when the shape of the connector is adapted to the course of at least one of the conductors in the area of the opening. In this way, friction between the connection piece and the conductor or a notch in the conductor due to the connection piece and thus mechanical damage can be avoided.
Beispielsweise führt wenigstens einer der Leiter im Bereich der Öffnung von der Längsachse des Verbindungsstücks weg. Beispielsweise verläuft der Leiter im Bereich der Öffnung in einem Winkel zur Längsachse. Insbesondere kann der Abstand des Leiters von einer Längsachse des Verbindungsstücks im Bereich der Öffnung größer oder gleich werden wie der Abstand der Wandung von der Längsachse im Flachbereich. Bei einem gänzlich flachen Verbindungsstück bestünde hier die Gefahr einer mechanischen Schädigung des Leiters durch das Verbindungsstück.For example, at least one of the conductors leads away from the longitudinal axis of the connecting piece in the region of the opening. For example, the conductor runs at an angle to the longitudinal axis in the area of the opening. In particular, the distance between the conductor and a longitudinal axis of the connecting piece in the area of the opening can be greater than or equal to the distance between the wall and the longitudinal axis in the flat area. In the case of a completely flat connection piece, there would be a risk of mechanical damage to the conductor by the connection piece.
In einer Ausführungsform weist wenigstens einer der Leiter eine mechanische Flexibilität auf. Beispielsweise ist wenigstens einer der Leiter als Draht, insbesondere als Litzendraht, ausgebildet. Der Litzendraht führt beispielsweise im Bereich der Öffnung von der Längsachse des Verbindungsstücks weg.In one embodiment, at least one of the conductors has mechanical flexibility. For example, at least one of the conductors is designed as a wire, in particular as a stranded wire. The stranded wire leads away from the longitudinal axis of the connecting piece in the area of the opening, for example.
Beispielsweise ist wenigstens einer der Leiter als starres Anschlusselement ausgebildet. Es kann sich insbesondere um einen Anschlusspin handeln. Das Anschlusselement verläuft beispielsweise auch im Bereich der Öffnung parallel zur Längsachse des Verbindungsstücks.For example, at least one of the conductors is designed as a rigid connection element. In particular, it can be a connection pin. The connection element also runs parallel to the longitudinal axis of the connecting piece in the region of the opening, for example.
Beispielsweise ist einer der Leiter im Bereich des Verbindungsstücks um einen anderen der Leiter gewickelt. Die Wicklung ermöglicht eine definierte Anordnung der Leiter zueinander während der Anbringung des Verbindungsstücks.For example, one of the conductors is wound around another of the conductors in the region of the connecting piece. the Winding enables a defined arrangement of the conductors to one another during the attachment of the connecting piece.
In einer Ausführungsform verbindet das Verbindungsstück einen Litzendraht mit einem starren Anschlusselement, insbesondere mit einem Anschlusspin. Der Litzendraht kann um den Anschlusspin im Bereich der Leiterverbindung gewickelt sein.In one embodiment, the connecting piece connects a stranded wire with a rigid connection element, in particular with a connection pin. The stranded wire can be wound around the connection pin in the area of the conductor connection.
Die Leiter weisen jeweils ein freies Ende auf. Am freien Ende ist der jeweilige Leiter beispielsweise abgeschnitten. Die freien Enden ragen beispielsweise aus einer der Öffnungen heraus oder sind innerhalb des Verbindungsstücks angeordnet. Beispielsweise sind die freien Enden im Bereich der gleichen Öffnung angeordnet. Bei einer derartigen Ausführungsform können die freien Enden besonders gut zusätzlich miteinander verlötet werden.The conductors each have a free end. The respective conductor is, for example, cut off at the free end. The free ends protrude, for example, from one of the openings or are arranged within the connecting piece. For example, the free ends are arranged in the area of the same opening. In such an embodiment, the free ends can also be soldered to one another particularly well.
Jeder der Leiter ist beispielsweise Bestandteil eines Bauteils oder mit einem Bauteil verbunden. Insbesondere können die Leiter mit einem Funktionsteil eines Bauteils verbunden sein. Dabei kann es sich beispielsweise um eine Induktivität handeln. Die Leiter reichen beispielsweise jeweils vom Bauteil oder Funktionsteil kommend in eine der Öffnungen in das Verbindungsstück hinein. Die Leiter können in dieselbe Öffnung oder in verschiedene Öffnungen hineinreichen.Each of the conductors is, for example, part of a component or is connected to a component. In particular, the conductors can be connected to a functional part of a component. This can be an inductance, for example. The conductors extend, for example, coming from the component or functional part into one of the openings in the connecting piece. The conductors can extend into the same opening or into different openings.
In einer Ausführungsform weist das Verbindungsstück zwei Öffnungen auf, wobei der Abstand der Wandung von der Längsachse zu beiden Öffnungen hin zunimmt. Insbesondere kann der Durchmesser und/oder Querschnitt des Verbindungsstücks zu beiden Öffnungen hin zunehmen. Das Verbindungsstück kann im Bereich jeder der Öffnungen wie oben beschrieben ausgebildet sein. Beispielsweise kann das Verbindungsstück im Bereich beider Öffnungen eine Zylinderform oder eine Trompetenform aufweisen.In one embodiment, the connecting piece has two openings, the spacing of the wall from the longitudinal axis increasing towards both openings. In particular, the diameter and / or cross section of the connecting piece can increase towards both openings. The connecting piece can be formed as described above in the region of each of the openings be. For example, the connecting piece can have a cylindrical shape or a trumpet shape in the area of both openings.
Das Verbindungsstück weist beispielsweise zwei Öffnungsbereiche auf, die jeweils in eine der Öffnungen münden. Zwischen den Öffnungsbereichen kann ein Flachbereich ausgebildet sein. In den Öffnungsbereichen nimmt der Abstand der Wandung von der Längsachse zur Öffnung hin zu. Im Flachbereich ist der Abstand der Wandung konstant. Die Öffnungsbereiche können gleich oder unterschiedlich ausgebildet sein.The connecting piece has, for example, two opening areas which each open into one of the openings. A flat area can be formed between the opening areas. In the opening areas, the distance of the wall from the longitudinal axis to the opening increases. In the flat area, the distance between the wall is constant. The opening areas can be designed the same or different.
Eine derartige Form des Verbindungsstücks ist beispielsweise besonders günstig zur Verbindung von Leitern, bei denen im Bereich jeder Öffnung wenigstens einer der Leiter von der Längsachse wegführt.Such a shape of the connecting piece is, for example, particularly favorable for connecting conductors in which at least one of the conductors leads away from the longitudinal axis in the area of each opening.
In einer Ausführungsform wird die Verbindung der Leiter lediglich durch das Verbindungsstück hergestellt. In einer alternativen Ausführungsform können die Leiter zusätzlich miteinander verlötet sein. Die Leiter können in einer Ausführungsform auch zusätzlich miteinander verschweißt sein. Beispielsweise wird durch das Verbindungsstück eine mechanische Befestigung der Leiter aneinander hergestellt und durch zusätzliches Löten oder Schweißen die elektrische Verbindung hergestellt. Das Löten oder Schweißen kann darüber hinaus auch die mechanische Verbindung verstärken.In one embodiment, the connection of the conductors is made only by the connector. In an alternative embodiment, the conductors can also be soldered to one another. In one embodiment, the conductors can also be welded to one another. For example, a mechanical fastening of the conductors to one another is made by the connecting piece and the electrical connection is made by additional soldering or welding. Soldering or welding can also strengthen the mechanical connection.
Gemäß einem weiteren Aspekt der Erfindung wird ein Bauteil mit der vorgehend beschriebenen Leiterverbindung angegeben. Es handelt sich insbesondere um ein elektrisches Bauteil, wie z. B. eine Induktivität.According to a further aspect of the invention, a component with the previously described conductor connection is specified. It is in particular an electrical component, such as. B. an inductor.
Das Bauteil weist beispielsweise einen Funktionsteil auf, von dem aus wenigstens einer der Leiter in eine Öffnung des Verbindungsstücks hineinführt. Es handelt sich hierbei beispielsweise um die Öffnung, zu der der Abstand der Wandung von der Längsachse hin zunimmt. Die Leiter können beispielsweise beide vom Funktionsteil kommend in dieselbe Öffnung hineinreichen.The component has, for example, a functional part from which at least one of the conductors leads into an opening in the connecting piece. This is, for example, the opening towards which the distance between the wall and the longitudinal axis increases. The conductors can, for example, both come from the functional part and extend into the same opening.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird ein Verfahren zur Herstellung der vorgehend beschriebenen Leiterverbindung angegeben.According to a further aspect of the present invention, a method for producing the conductor connection described above is specified.
Im Verfahren wird ein flaches metallisches Bandstück bereitgestellt. Das Bandstück ist beispielsweise von einem längeren Band abgetrennt. Es werden zwei aneinander angeordnete Leiter bereitgestellt. Beispielsweise ist einer der Leiter um den anderen Leiter zumindest bereichsweise gewickelt. Die Leiter können beispielsweise auch lediglich aneinander anliegen.In the method, a flat piece of metallic tape is provided. The piece of tape is separated from a longer tape, for example. Two conductors arranged next to one another are provided. For example, one is the conductor is wrapped around the other conductor at least in some areas. The conductors can, for example, only rest against one another.
Das Bandstück wird um die beiden Leiter herumgebogen, so dass die beschriebene Leiterverbindung und/oder das Verbindungsstück erhalten wird. Dabei wird eine Pressverbindung der Leiter durch das Verbindungsstück erhalten. Anschließend werden die Leiter beispielsweise im Bereich einer der Öffnungen abgetrennt.The piece of tape is bent around the two conductors so that the described conductor connection and / or the connecting piece is obtained. A press connection of the conductors is obtained by the connecting piece. The conductors are then cut off, for example in the area of one of the openings.
Die Leiterverbindung kann eine ausreichende mechanische Stabilität aufweisen, so dass keine weitere Verbindungstechnik erforderlich ist. Alternativ kann eine zusätzliche elektrische und/oder mechanische Verbindung nach Herstellung der Pressverbindung erfolgen. Eine derartige zusätzliche Verbindung erfolgt beispielsweise durch Löten oder durch Schweißen. Die zusätzliche Verbindung wird beispielsweise im Bereich der abgetrennten Enden der Leiter hergestellt.The conductor connection can have sufficient mechanical stability so that no further connection technology is required. Alternatively, an additional electrical and / or mechanical connection can be made after the press connection has been established. Such an additional connection is made, for example, by soldering or welding. The additional connection is made, for example, in the area of the severed ends of the conductors.

Alle Eigenschaften, die in Bezug auf das Verbindungsstück, das Bauteil oder das Verfahren offenbart sind, sind auch entsprechend in Bezug auf die anderen Aspekte offenbart, auch wenn die jeweilige Eigenschaft nicht explizit im Kontext der anderen Aspekte erwähnt wird.Several aspects of an invention are described in the present disclosure.

Die Leiterverbindung 100 ist Teil eines elektrischen Bauteils 5. Einer oder beide der Leiter 2, 3 führen von einem Funktionsteil 4 des elektrischen Bauteils 5 zum Verbindungsstück 1. Bei dem Funktionsteil 4 kann es sich beispielsweise um ein elektrisches Funktionsteil eines Bauteils handeln, beispielsweise um eine Induktivität, oder um ein mechanisches Funktionsteil, beispielsweise um einen Träger.The
Das Verbindungsstück 1 ist als metallisches Bandstück 18 ausgebildet, das um eine Längsachse 6 gebogen ist. Die Längsachse 6 ist eine zentrale Achse in Längsrichtung des Verbindungstücks 1. Die Längsachse 6 kann eine Symmetrieachse des Verbindungsstücks 1 darstellen. Die Längsachse 6 entspricht beispielsweise einer Längsachse der Leiter 2, 3.The connecting
Zur Herstellung der Verbindung wird ein flaches Bandstück von einem metallischen Band abgeschnitten, um die Leiter 2, 3 gebogen und dabei an die Leiter 2, 3 angepresst. Dieses Verfahren wird im Detail in Verbindung mit
Die Leiter 2, 3 werden durch das Verbindungstück 1 somit mechanisch miteinander verbunden. Die Verbindung kann ausreichende Stabilität aufweisen, so dass keine Lötung und kein andere, weitere Verbindungstechnik benötigt werden. Alternativ können die mit dem Verbindungsstück 1 verbundenen Leiter 2, 3 zusätzlich durch Löten und/oder Schweißen miteinander verbunden werden. Die Verbindung mittels eines Verbindungsstücks 1 ist beispielsweise leichter herstellbar und zuverlässiger als die Verbindung mittels eines zusätzlichen Drahtes, der um die Leiter 2, 3 gewickelt wird.The
Ein derartiges Verbindungsstück 1 wird üblicherweise als "splice crimp" bezeichnet. Das Verbindungsstück 1 unterscheidet sich von einer vorgefertigten Hülse, in welche ein oder mehrere Leiter eingesteckt werden. Das vorliegende Verbindungsstück 1 erhält seine Hülsenform erst während der Umformung um die Leiter 2, 3. Die Leiter 2, 3 werden somit nicht in das Verbindungsstück 1 eingesteckt. Das Verbindungsstück 1 ist mit keinem der Leiter 2, 3 einstückig ausgebildet.Such a
Das Verbindungsstück 1 weist als Material beispielsweise Kupfer, Messing, Bronze oder andere Kupfer-Legierungen auf.The connecting
Bei dem ersten Leiter 2 handelt es sich beispielsweise um ein starres Anschlusselement. Beispielsweise handelt es sich um einen Anschlussstift, der auch als Pin bezeichnet wird. Bei dem zweiten Leiter 3 handelt es sich beispielsweise um einen biegbaren Draht, beispielsweise um einen Litzendraht. Der Litzendraht kann Kupfer aufweisen. Der Litzendraht weist beispielsweise 2 bis 5000 Einzeldrähte auf. Der zweite Leiter 3 ist beispielsweise wenigstens abschnittsweise um den ersten Leiter 2 gewickelt.The
Es kann sich alternativ bei beiden Leitern 2, 3 auch um dieselbe Leiterart handeln. Weiterhin können auch mehr als zwei Leiter 2, 3 durch das Verbindungsstück 1 verbunden werden. Beispielsweise werden mehrere Litzendrähte und ein Anschlussstift miteinander verbunden.Alternatively, the two
Die Leiter 2, 3 führen beispielsweise ausgehend von einem Funktionselement 4 des Bauteils 5 in das Verbindungsstück 1 hinein. Die Leiter 2, 3 weisen beispielsweise jeweils ein freies Ende 9, 10 auf.The
Das Verbindungsstück 1 weist zwei Öffnungen 7, 8 auf. Die Öffnungen 7, 8 sind an gegenüberliegenden Stirnseiten des Verbindungsstücks 1 ausgebildet. In wenigstens eine der Öffnungen 7, 8 ist wenigstens einer der Leiter 2, 3 in das Verbindungsstück 1 hinein- und/oder herausgeführt.The connecting
Bei der abgebildeten Ausführungsform reicht jeder Leiter 2, 3 vom Funktionselement 4 ausgehend zuerst in die erste Öffnung 7 hinein. Es kann aber auch der Fall sein, dass die Leiter 2, 3 von unterschiedlichen Öffnungen in das Verbindungsstück 1 hineinreichen. Beispielsweise reicht der erste Leiter 2 vom Funktionselement 4 kommend in die erste Öffnung 7 hinein und der zweite Leiter 3, z.B. ausgehend von einem weiteren Funktionselement (nicht abgebildet), durch die zweite Öffnung 8 hinein.In the embodiment shown, each
Vorliegend ragen beide freie Enden 9, 10 durch die zweite Öffnung 8 aus dem Verbindungsstück 1 heraus. Ein oder beide freie Enden 9, 10 können auch innerhalb des Verbindungsstücks 1 liegen. Weiterhin können auch ein oder beide freie Enden 9, 10 aus der ersten Öffnung 7 herausragen, durch die die Leiter 2, 3 in das Verbindungsstück 1 hineinreichen. Beispielsweise reicht der zweite Leiter 3 durch die erste Öffnung 7 in das Verbindungsstück 1 hinein und ist derart umgebogen, dass sein freies Ende 9 wieder aus der ersten Öffnung 7 herausragt.In the present case, both
Das Verbindungsstück 1 weist eine Wandung 11 auf, deren Abstand a von der Längsachse 6 in Richtung der ersten Öffnung 7 zunimmt. Entsprechend führt die Kontur der Wandung 11 im Längsschnitt in Richtung der ersten Öffnung 7 von der Längsachse 6 weg. Das Verbindungsstück 1 kann auch umlaufend den zunehmenden Abstand a der Wandung 11 aufweisen.The connecting
Beispielsweise nimmt der Durchmesser D des Verbindungsstücks 1 in Richtung der ersten Öffnung 7 zu. Das Verbindungsstück 1 hat beispielsweise seinen größten Durchmesser an der ersten Öffnung 7. Auch der Querschnitt des Verbindungsstücks 1 nimmt beispielsweise in Richtung der ersten Öffnung 7 zu.For example, the diameter D of the connecting
Das Verbindungsstück 1 weist beispielsweise einen ersten Öffnungsbereich 12 auf, in dem der von der Längsachse 6 wegführende Verlauf der Kontur der Wandung 11 vorhanden ist. Weiterhin weist das Verbindungsstück 1 einen Flachbereich 13 auf, in dem der Abstand a der Wandung 11 von der Längsachse 6 gleichbleibend ist.The connecting
Aufgrund der Zunahme des Abstandes der Wandung 11 von der Längsachse 6 kann die mechanische Beanspruchung der Leiter 2, 3 verringert und damit eine Beschädigung der Leiter 2, 3 verhindert werden. Die Kontur der Wandung 11 des Verbindungsstücks 1 ist beispielsweise an den Verlauf des zweiten Leiters 3 angepasst. Der Öffnungsbereich 12 ist damit nicht als Einführhilfe geformt, sondern zur Verhinderung mechanischer Beschädigungen ausgebildet.Due to the increase in the distance between the
Dies ist besonders vorteilhaft im Fall eines Leiters 3, der im Bereich der ersten Öffnung 7 von der Längsachse 6 wegführend verläuft. Die Haupterstreckungsrichtung des Leiters 3 verläuft dabei im Bereich der Öffnung 7 in einem Winkel zur Längsachse 6. Der Leiter 3 führt beispielsweise auch vom ersten Leiter 2 weg, der parallel zur Längsachse verläuft. Die Haupterstreckungsrichtungen der Leiter 2, 3 verläuft somit zumindest im Bereich der ersten Öffnung 7 nicht parallel.This is particularly advantageous in the case of a
Insbesondere nimmt der Abstand 1 des zweiten Leiters 3 von der Längsachse 6 im Bereich der Öffnung 7 nach außen hin zu. Der Abstand 1 im Bereich der Öffnung 7 kann dabei beispielsweise gleich oder größer als der Abstand der Wandung 11 im Flachbereich 13 sein.In particular, the
Das Funktionselement 4 weist beispielsweise nur einen geringen Abstand von dem Verbindungsstück 1 auf. Somit ist nur ein schmaler Spalt zwischen dem Verbindungsstück 1 und dem Funktionselement 4 vorhanden. Beispielsweise ist der Abstand d zwischen dem Funktionselement 4 und dem Verbindungsstück 1 kleiner gleich 1 mm. In diesem Fall ist die mechanische Beanspruchung eines von der Längsachse wegführenden Leiters 3 besonders hoch. Durch die angepasste Kontur der Wandung 11 des Verbindungsstücks 1 werden Beschädigungen verhindert. Dies kann beispielsweise auch einen Einsatz des Bauteils 5 bei höheren Temperaturen ermöglichen.The functional element 4 has, for example, only a small distance from the connecting
Insgesamt weist das Verbindungsstück 1 beispielsweise eine Erstreckung entlang der Längsachse 6 von maximal 30 mm auf. Die Erstreckung entlang der Längsachse 6 ist beispielsweise mindestens 1.5 mm. Der erste Öffnungsbereich 12 weist beispielsweise eine Erstreckung t entlang der Längsachse 6 von 0.15 % bis 0.5 % der Erstreckung des Verbindungsstücks 1 auf.Overall, the connecting
Die Kontur der Wandung 11 ist beispielsweise konkav ausgebildet. Beispielsweise nimmt der Winkel zwischen der Konturlinie der Wandung 11 und der Längsachse 6 zur Öffnung 7 hin zu. Beispielsweise weist das Verbindungsstück 1 wenigstens im Bereich der Öffnung 7 die Form einer Trompete auf.The contour of the
Alternativ kann die Kontur der Wandung 11 auch linear verlaufen. In diesem Fall verläuft die Konturlinie der Wandung 11 in einem festen Winkel zur Längsachse 6. Beispielsweise weist das Verbindungsstück 1 wenigstens im Bereich der Öffnung 7 die Form eines Zylinders auf.Alternatively, the contour of the
Anstatt der ersten Öffnung 7 kann auch die zweite Öffnung 8 eine von der Längsachse 6 wegführende Kontur der Wandung 11 aufweisen. Weiterhin kann es auch vorgesehen sein, dass beide Öffnungen 7, 8 eine von der Längsachse 6 wegführende Kontur der Wandung 11 aufweisen. Dies ist besonders vorteilhaft, wenn aus beiden Öffnungen 7, 8 Leiter herausragen, die von der Längsachse 6 wegführend verlaufen. Weiterhin kann bei der Ausbildung beider Öffnungen 7, 8 mit einer von der Längsachse 6 wegführenden Kontur der Wandung 11 das Verbindungsstück 1 symmetrisch ausgebildet sein, was die Herstellung des Verbindungsstücks 1 vereinfacht und einen flexibleren Einsatz ermöglicht.Instead of the
Das Verbindungsstück 1 weist zwei seitliche Bereiche 14, 15 auf, die sich überlappen. Insbesondere überlappen sich die Bereiche 14, 15 in einer Richtung senkrecht zur Längsachse 6, so dass dort der zweite Bereich 15 über dem ersten Bereich 14 angeordnet ist. Die Überlappung erstreckt sich beispielsweise in Längsrichtung über das gesamte Verbindungsstück 1. Ein Verbindungsstück 1 mit derartigen überlappenden Bereichen lässt sich leicht von einer vorgeformten Hülse unterscheiden.The connecting
Die überlappenden Bereiche 14, 15 des Verbindungsstücks 1 liegen vorliegend eng aneinander an. Dies trifft insbesondere für den Flachbereich 13 des Verbindungsstücks 1 zu. Im Öffnungsbereich 12 ist ein enges Anliegen der überlappenden Bereiche 14, 15 nicht in jedem Fall gegeben, wie z.B. in
Das Verbindungsstück 1 weist beispielsweise eine von der Längsachse 6 wegführende Kontur der Wandung 11 in einem Bereich 16 auf, in dem der zweite Leiter 3 in die Öffnung 7 hineinführt. In einem weiteren Bereich 17, der beispielsweise vom ersten Leiter 2 aus gesehen dem Bereich 16 gegenüberliegt, kann das Verbindungsstück 1 eine andere Kontur aufweisen. Beispielsweise verläuft die Kontur der Wandung 11 dort parallel zur Längsachse 6.The connecting
Die
Der flexible erste Leiter 3 ist teilweise um den starren zweiten Leiter 2 gewickelt. Der Leiter 3 reicht beispielsweise von einem Funktionselement 4 kommend in die erste Öffnung 7 hinein und aus der zweiten Öffnung 8 heraus. Jenseits der zweiten Öffnung 8 ist der erste Leiter 3 beispielsweise umgebogen und reicht durch die zweite Öffnung 8 wieder in das Verbindungsstück 1 hinein. Das Ende des zweiten Leiters 3 ist im Verbindungsstück 1 angeordnet.The flexible
Insbesondere sind hier die Leiter 2, 3 innerhalb des Verbindungsstücks 1 zu sehen. Die Leiter 2, 3 sind aneinander angepresst. Der flexible Leiter 3 ist teilweise aufgrund der Pressung verformt. Insbesondere sind Litzendrähte des flexiblen Leiters 3 verformt.In particular, the
Die zu verbindenden Leiter 2, 3 werden aneinander angeordnet. Beispielsweise wird der zweite Leiter 3 um den ersten Leiter 2 gewickelt. Die aneinander angeordneten Leiter 2, 3 werden in ein Halteteil 20 der Umformvorrichtung 19 eingelegt.The
Es wird ein metallisches Bandstück 18 bereitgestellt. Das Bandstück 18 ist zu Beginn des Verfahrens beispielsweise flach ausgebildet. Das Bandstück 18 wird von einem längeren Band, beispielsweise einer Rolle, abgetrennt. Das Bandstück 18 wird in ein weiteres Halteteil 21 der Umformvorrichtung 19 eingelegt.A piece of
Die Umformvorrichtung 19 weist ein oder mehrere bewegliche Umformteile 22, insbesondere bewegliche Stempel, auf. Die Umformteile 22 werden zum Metallstück 18 bewegt und drücken seitliche Bereiche des Metallstücks 18 nach unten. Somit legen sich die seitlichen Bereiche um die Leiter 2, 3 herum.The shaping
Die Umformteile 22 erstrecken sich beispielsweise nicht entlang eines Bereichs 23 des Metallstücks 18, aus dem der Öffnungsbereich 12 mit der von der Längsachse wegführenden Kontur der Wandung 11 gebildet wird (siehe
Die Umformvorrichtung 19 kann weitere bewegliche Teile zur Umformung des Bandstücks 18 und zur Ausbildung der Pressverbindung aufweisen. Die Umformteile 22 können auch um die Leiter 2, 3 herumgeführt werden.The shaping
Die Leiter 2, 3 können nach dem Verbinden durch das Verbindungsstück 1 jenseits einer der Öffnungen 7, 8, insbesondere jenseits der zweiten Öffnung 8, abgeschnitten werden. Die Leiter 2, 3 weisen dann nicht-isolierte, für eine Lötung gut zugängliche Enden auf. Dies erleichtert und verkürzt den Lötprozess. Zudem werden Lotbrücken vermieden.After being connected by the connecting
Alternativ erfolgt nach dem Verbinden keine zusätzliche Verbindung, insbesondere keine Löt- oder Schweißverbindung, so dass die Leiter 2, 3 lediglich durch das Verbindungsstück 1 miteinander verbunden werden.Alternatively, after the connection, there is no additional connection, in particular no soldered or welded connection, so that the

Dies ist besonders vorteilhaft für den Fall, dass aus beiden Öffnungen 7, 8 Leiter 3, 26 herausragen, die von der Längsachse 6 nach außen hin wegführen. Es kann sich hier um denselben Leiter oder um zwei unterschiedliche Leiter handeln. Beispielsweise handelt es sich bei den Leitern 3, 26 um zwei flexible Leiter, insbesondere Litzendrähte, die durch das Verbindungsstück 1 mit einem starren Leiter 2 verbunden sind.This is particularly advantageous in the event that
