Definitions
- the invention relates to an electrical connection device for producing a solder joint according to the preamble of claim 1 and to a method for the production thereof according to claim 17.
- Solder joints are among the most common types of connection in the field of electrical and electronic equipment technology.
- an electrical connection between connecting wires or generally connecting lines on the one hand and electrically conductive contact elements on the other side are to be made, which consist for example of non-solderable materials.
- strip conductors as may be provided on a plate-shaped substrate, or generally plate-shaped conductors in the form of metal sheets or metal strips, etc. belong.
- Non-solderable strip conductors are often used in the form of thin-walled sheets, which can be mounted, for example, on dielectric substrate.
- the strip conductors or strip lines can also be mounted in front of a metallic surface using air as a dielectric.
- Strip waveguides which are mounted at a distance in front of an electrically conductive reflector plate and are held by means of an insulating body which is mounted on the reflector plate, are frequently used, in particular in mobile radio technology.
- an electrical connection connection must optionally be made using copper wires, etc. It would be advantageous if such good solderable connection wires can be soldered to the strip conductors.
- galvanic contacts are known in which, for example, two printed circuit boards or printed conductors are screwed together.
- a method and a device for fastening an insert in a plate material is for example from CH 383 082 known. It is assumed that a metal, a sheet or an insulating material, which is designed plate-shaped.
- a cylindrical insert is to be pressed, which is provided in a partial height in the axial direction on its outer periphery with a knurling.
- a pressing tool ie a punch and serving as a counter support cylindrical hollow punch can then be pre-pressed in the direction of plate, the cylindrical insert, wherein a cylindrical material portion of the plate is punched out by the hollow punch.
- the cylindrical insert can be pressed.
- the outer circumference of the press-fit piece corresponds in principle to the inner diameter of the cylindrical punched-out bore, wherein only the knurling of the insert piece may have a slightly larger outer diameter in order to be able to scrape the axially extending flanks of the knurling into the surface of the cylindrical recess in the plate during assembly. This is to ensure a good interference fit.
- a comparable solution is also from the DE 10 2007 057 501 A1 known.
- a press-in connection using a bolt with an outer contour is preferably proposed in the form of knurling, which is adapted to a correspondingly matched by its diameter surface design of a hole in a busbar.
- the anchoring of a two-stage plug element with stepped arranged Jardinrändelung and a correspondingly stepped recess of a wall portion of a housing wall is made of DE 102 59 803 B3 to be known as known. Again, by the interaction of the knurling on the outer circumference of the plug-in element and the inner surface of the stepped bore to be ensured by notching effected optimum interference fit.
- the WO-2005 079 127 discloses an electrical connection device as in the preamble of appended claim 1.
- connection device by the features specified in claim 1 and with respect to a corresponding manufacturing method for such a connection device according to the features indicated in claim 17.
- Advantageous embodiments of the invention are specified in the subclaims.
- press-fit bolts have a stamp-shaped connection side on which a solder connection can be made.
- the press-in bolts are pressed in the manner of a punch through a plate-shaped non-solderable material, whereby the non-solderable material is pierced in particular as strip conductor material, which receives a broken circumferential edge material in the penetration of the press-fit pin. With this edge of the material, a base peripheral area of the press-in pin is held while achieving high press-in and clamping forces, the head of the press-in pin protruding beyond this strip conductor material edge being available as a soldering point.
- the clamping portion on the peripheral edge of the press-in pin which cooperates with the broken-up during the pressing-in edge of the material Vietnamese solderable plate material and holds the press-in bolts may preferably be provided with a circumferential knurling. This creates an excellent frictional connection between the wall material of the press-in pin and the non-solderable material adjacent thereto.
- the press-fit bolt is ultimately used as a press or stamping die to deform a corresponding plate-shaped material, wherein the press-in pin is then left behind in this quasi after penetration of the non-solderable material.
- the advantage also lies in the fact that the corresponding deformation of the non-solderable material is carried out by the press-in pin itself, so that ultimately there are no tolerance deviations in the press connection between the outer and inner part.
- the flanged edge of the material which is formed during the pressing of the press-in and protrudes beyond the thickness of the plate-shaped material, at the same time also serves to prevent tilting of the press-in pin. Because of the flanged edge of the material of the bolt is held with a larger total area of the surrounding material edge in a press fit. In the case of thin sheets, otherwise the penetration in the plate material would be critical since the pin could otherwise tilt more easily if pressure or tensile forces are applied laterally. The solution according to the invention therefore also significantly improves the long-term stability under radial tensile or compressive loads.
- the electrical connection connection thus formed is particularly suitable for the connection of coaxial cables, with particularly good solder joints are then also feasible when the press-in pin, for example, tinned or silvered or, for. made of brass, etc.
- the press-in pin is provided in the circumferential direction with at least one circumferential recess or groove, which may be formed concave in axial vertical section, for example (different cross-sectional configurations of this groove are possible). It is also possible that, for example, two such, circumferential in the circumferential direction on the outer circumference of the Einpressbolzens grooves are provided which are offset from one another in an axial height. These at least one or more grooves should come to lie in the compressed state in the range of the material thickness of the plate-shaped or sheet-like material. As a result of this embodiment, in the remaining contact region, an even increased pressure and contact pressure between the plate-shaped or sheet-like material on the one hand and the circumferential surface of the injection bolt is ensured, which avoids possible intermodulation even better and safer.
- the invention can be used in all relevant areas in which electrically solderable and electrically non-solderable materials are to be soldered together. This is especially true in a solder joint in electrically highly conductive materials such as coaxial inner conductors with strip conductors.

Description
Die Erfindung betrifft eine elektrische Anschlusseinrichtung zur Herstellung einer Lötverbindung nach dem Oberbegriff des Anspruches 1 sowie ein Verfahren zu deren Herstellung nach Anspruch 17.The invention relates to an electrical connection device for producing a solder joint according to the preamble of
Lötverbindungen gehören auf dem Gebiet der elektrischen und elektronischen Gerätetechnik mit zu den häufigsten Verbindungsarten.Solder joints are among the most common types of connection in the field of electrical and electronic equipment technology.
Dabei gibt es allerdings auch Anwendungsfälle, bei denen beispielsweise eine elektrische Verbindung zwischen Anschlussdrähten oder allgemein Anschlussleitungen auf der einen Seite und elektrisch leitfähigen Kontaktelementen auf der anderen Seite vorgenommen werden sollen, die beispielsweise aus nicht lötbaren Materialien bestehen. Dazu können beispielsweise auch Streifenleiter, wie sie auf einem plattenförmigen Substrat vorgesehen sein können, oder allgemein plattenförmige Leiter in Form von Metallblechen oder Metallstreifen etc. gehören.However, there are also applications in which, for example, an electrical connection between connecting wires or generally connecting lines on the one hand and electrically conductive contact elements on the other side are to be made, which consist for example of non-solderable materials. For this purpose, for example, strip conductors, as may be provided on a plate-shaped substrate, or generally plate-shaped conductors in the form of metal sheets or metal strips, etc. belong.
Hier stellt sich die Frage, wie eine dauerhafte elektrisch lötfähige Verbindung von einem elektrisch gut leitfähigen Material oder Metall zu einer derartigen Streifenleitung oder einem anderen aus nicht lötbarem Material bestehenden Leiter hergestellt werden soll.This raises the question of how to make a permanent electrically solderable connection of a highly electrically conductive material or metal to such a stripline or other consisting of non-solderable material conductor.
Nicht lötbare Streifenleiter werden häufig in Form von dünnwandigen Blechen eingesetzt, die beispielsweise auf dielektrischem Trägermaterial montiert werden können. Im Gegensatz dazu können die Streifenleiter oder Streifenleitungen auch unter Verwendung von Luft als Dielektrikum vor einer metallischen Fläche montiert werden. Insbesondere in der Mobilfunktechnik kommen häufig Streifenleiter zum Einsatz, die in einem Abstand vor einem elektrisch leitfähigen Reflektorblech montiert sind und dabei mittels eines Isolationskörpers gehalten werden, der auf dem Reflektorblech montiert ist. An einem derartigen Streifenleiter muss dann beispielsweise eine elektrische Anschlussverbindung gegebenenfalls unter Verwendung von Kupferdrähten etc. hergestellt werden. Vorteilhaft wäre, wenn derartige gut lötfähige Anschlussdrähte auf den Streifenleitern angelötet werden können.Non-solderable strip conductors are often used in the form of thin-walled sheets, which can be mounted, for example, on dielectric substrate. In contrast, the strip conductors or strip lines can also be mounted in front of a metallic surface using air as a dielectric. Strip waveguides, which are mounted at a distance in front of an electrically conductive reflector plate and are held by means of an insulating body which is mounted on the reflector plate, are frequently used, in particular in mobile radio technology. At such a strip conductor then, for example, an electrical connection connection must optionally be made using copper wires, etc. It would be advantageous if such good solderable connection wires can be soldered to the strip conductors.

Demgegenüber ist es Aufgabe der vorliegenden Erfindung, eine Möglichkeit bereitzustellen, eine gute elektrische Verbindung zwischen lötfähigen und nicht lötfähigen oder nur schlecht lötfähigen Materialien herzustellen, und zwar auf einfache und kostengünstig realisierbare Weise. Dabei vor allem sichergestellt werden, dass intermodulationsstabile und intermodulations-freie elektrische Verbindungen realisierbar sind.In contrast, it is an object of the present invention to provide a way to produce a good electrical connection between solderable and not solderable or poorly solderable materials, in a simple and inexpensive manner feasible. In particular, it must be ensured that intermodulation-stable and intermodulation-free electrical connections can be implemented.

Die Aufgabe wird bezüglich einer Anschlusseinrichtung durch die im Anspruch 1 angegebenen Merkmale und bezüglich eines entsprechenden Herstellverfahrens für eine derartige Anschlusseinrichtung gemäß den im Anspruch 17 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved with respect to a connection device by the features specified in
Es muss als ausgesprochen überraschend bezeichnet werden, dass im Rahmen der Erfindung durch vergleichsweise einfache Maßnahmen eine optimale elektrische Verbindung zwischen lötfähigen und nicht lötfähigen Materialien hergestellt werden kann.It must be described as extremely surprising that in the context of the invention by comparatively simple measures an optimal electrical connection between solderable and non-solderable materials can be made.
Erfindungsgemäß wird dies durch Verwendung von sog. Einpressbolzen realisiert, die aus einem lötfähigen Material bestehen und in streifen- oder plattenförmige Materialien eingepresst werden, die selbst nicht lötfähig oder nur äußerst schlecht lötfähig sind.According to the invention this is achieved by using so-called. Press-in, which consist of a solderable material and are pressed into strip or plate-shaped materials that are not themselves solderable or extremely poorly solderable.
Diese Einpressbolzen weisen eine stempelförmige Anschlussseite auf, auf der eine Lötverbindung hergestellt werden kann. Dabei werden die Einpressbolzen nach Art eines Stempels durch ein plattenförmiges nicht lötbares Material eingepresst, wodurch das nicht lötfähige Material wie insbesondere Streifenleitermaterial durchbohrt wird, welches im Bereich der Durchdringung durch den Einpressbolzen einen aufgebrochenen umlaufenden Materialrand erhält. Mit diesem Materialrand wird ein Basisumfangsbereich des Einpressbolzens unter Erzielung hoher Einpress- und Klemmkräfte gehalten, wobei der über diesen umgebördelten Streifenleiter-Materialrand überstehende Kopf des Einpressbolzens als Anlötstelle zur Verfügung steht.These press-fit bolts have a stamp-shaped connection side on which a solder connection can be made. In this case, the press-in bolts are pressed in the manner of a punch through a plate-shaped non-solderable material, whereby the non-solderable material is pierced in particular as strip conductor material, which receives a broken circumferential edge material in the penetration of the press-fit pin. With this edge of the material, a base peripheral area of the press-in pin is held while achieving high press-in and clamping forces, the head of the press-in pin protruding beyond this strip conductor material edge being available as a soldering point.
Der Klemmabschnitt am Umfangsrand des Einpressbolzens, der mit dem während des Einpressens aufgebrochenen umlaufenden Materialrand des nicht lötfähigen Plattenmaterials zusammenwirkt und den Einpressbolzen hält, kann bevorzugt mit einer umlaufenden Rändelung versehen sein. Dies erzeugt eine hervorragende kraftschlüssige Verbindung zwischen dem Wandmaterial des Einpressbolzens und dem daran anliegenden nicht lötfähigen Material.The clamping portion on the peripheral edge of the press-in pin, which cooperates with the broken-up during the pressing-in edge of the material nicht solderable plate material and holds the press-in bolts may preferably be provided with a circumferential knurling. This creates an excellent frictional connection between the wall material of the press-in pin and the non-solderable material adjacent thereto.
Der Einpressbolzen wird letztlich wie ein Press- oder Prägestempel verwendet, um ein entsprechendes plattenförmiges Material zu verformen, wobei der Einpressbolzen dann quasi nach Durchdringung des nicht lötfähigen Materials in diesem zurückbelassen wird.The press-fit bolt is ultimately used as a press or stamping die to deform a corresponding plate-shaped material, wherein the press-in pin is then left behind in this quasi after penetration of the non-solderable material.
Der Vorteil liegt dabei auch darin, dass die entsprechende Verformung des nicht lötfähigen Materials durch den Einpressbolzen selbst erfolgt, so dass es letztlich keine Toleranzabweichungen bei der Pressverbindung zwischen Außen- und Innenteil gibt.The advantage also lies in the fact that the corresponding deformation of the non-solderable material is carried out by the press-in pin itself, so that ultimately there are no tolerance deviations in the press connection between the outer and inner part.
Die Ausbildung eines sauberen umlaufenden Materialabschnittes, welches während des Einpressvorgangs des Einpressbolzens umgebogen und am Außenumfang des Einpressbolzens anliegt, wird dadurch realisiert, dass bevorzugt an der betreffenden Stelle des streifen- oder plattenförmigen Materials eine Bohrung oder Stanzung zunächst eingebracht wird, die das Zentrum zum Einpressen des Einpressbolzens bildet.The formation of a clean circumferential material portion which is bent during the press-fitting of Einpressbolzens and rests on the outer periphery of Einpressbolzens, is realized in that preferably at the relevant point of the strip or plate-shaped material, a bore or punching is first introduced, which is the center for pressing of Einpressbolzens forms.
Der umgebördelte Materialrand, der beim Einpressen des Einpressbolzens entsteht und über die Dicke des plattenförmigen Materials übersteht, dient gleichzeitig auch dazu, ein Verkippen des Einpressbolzens zu vermeiden. Denn durch den umgebördelten Materialrand wird der Bolzen mit einer größeren Gesamtfläche von dem ihn umgebenden Materialrand im Presssitz gehalten. Bei dünnen Blechen wäre ansonsten die Durchdringung im Plattenmaterial kritisch, da der Bolzen ansonsten bei seitlich ansetzenden Druck- oder Zugkräften leichter verkippen könnte. Durch die erfindungsgemäße Lösung wird also auch die Langzeitstabilität bei radialen Zug- oder Druckbelastungen deutlich verbessert.The flanged edge of the material, which is formed during the pressing of the press-in and protrudes beyond the thickness of the plate-shaped material, at the same time also serves to prevent tilting of the press-in pin. Because of the flanged edge of the material of the bolt is held with a larger total area of the surrounding material edge in a press fit. In the case of thin sheets, otherwise the penetration in the plate material would be critical since the pin could otherwise tilt more easily if pressure or tensile forces are applied laterally. The solution according to the invention therefore also significantly improves the long-term stability under radial tensile or compressive loads.
Die so gebildete elektrische Anschlussverbindung eignet sich vor allem auch zum Anschluss von Koaxialkabeln, wobei besonders gute Lötverbindungen dann auch realisierbar sind, wenn der Einpressbolzen beispielsweise verzinnt oder versilbert ist oder z.B. aus Messing etc. besteht.The electrical connection connection thus formed is particularly suitable for the connection of coaxial cables, with particularly good solder joints are then also feasible when the press-in pin, for example, tinned or silvered or, for. made of brass, etc.
Auch eventuell bestehende Oxidschichten an der Oberfläche des nicht lötfähigen Materials sind letztlich nicht hinderlich, da durch das Einpressen des Einpressbolzens und durch die Materialverformung des nicht lötfähigen Materials ein Selbstreinigungseffekt einhergeht und insbesondere bei gerändelten Einpressbolzen diese Rändelung sich noch besser in das nicht lötfähige Material einkerbt und einschneidet.Even existing oxide layers on the surface of the non-solderable material are ultimately not a hindrance, as by the pressing of the Einpressbolzens and by the material deformation of the non-solderable material is accompanied by a self-cleaning effect and especially knurled Einpressbolzen this knurling even better notched into the non-solderable material and cuts.
In einer Weiterbildung der Erfindung ist es auch möglich, dass der Einpressbolzen in Umfangsrichtung mit zumindest einer umlaufenden Vertiefung oder Nut versehen ist, die im axialen Vertikalschnitt beispielsweise konkav geformt sein kann (wobei unterschiedliche Querschnittsausbildungen dieser Nut möglich sind). Ebenso möglich ist es auch, dass beispielsweise zwei derartige, in Umfangsrichtung am Außenumfang des Einpressbolzens umlaufende Nuten vorgesehen sind, die in einer axialen Höhe versetzt zueinander liegen. Diese zumindest eine oder die mehreren Nuten sollen dabei in verpresstem Zustand im Bereich der Materialdicke des platten- oder blechförmigen Materials zu liegen kommen. Durch diese Ausbildung wird im verbleibenden Kontaktbereich ein noch erhöhter Anpress- und Kontaktdurck zwischen dem platten- oder blechförmigen Material zum einen und der Umfangsoberfläche des Einpressbolzens gewährleistet, wodurch mögliche Intermodulationen noch besser und sicherer vermieden werden.In one embodiment of the invention, it is also possible that the press-in pin is provided in the circumferential direction with at least one circumferential recess or groove, which may be formed concave in axial vertical section, for example (different cross-sectional configurations of this groove are possible). It is also possible that, for example, two such, circumferential in the circumferential direction on the outer circumference of the Einpressbolzens grooves are provided which are offset from one another in an axial height. These at least one or more grooves should come to lie in the compressed state in the range of the material thickness of the plate-shaped or sheet-like material. As a result of this embodiment, in the remaining contact region, an even increased pressure and contact pressure between the plate-shaped or sheet-like material on the one hand and the circumferential surface of the injection bolt is ensured, which avoids possible intermodulation even better and safer.
Die Erfindung kann in allen relevanten Bereichen eingesetzt werden, in denen elektrisch lötfähige und elektrisch nicht lötfähige Materialen miteinander verlötet werden sollen. Dies gilt insbesondere bei einer Lötverbindung bei elektrisch gut leitenden Materialien wie beispielsweise koaxialen Innenleitern mit Streifenleitern.The invention can be used in all relevant areas in which electrically solderable and electrically non-solderable materials are to be soldered together. This is especially true in a solder joint in electrically highly conductive materials such as coaxial inner conductors with strip conductors.

Wie erwähnt, kommt also letztlich der lötfähige Bolzenkopf 7, der an seiner Oberseite eine lötfähige Fläche LF aufweist, im Abstand zur Ebene des platten- oder streifenförmigen Materials 1 zu liegen, und zwar auf der einen Seite 1a des platten- oder streifenförmigen Materials 1, auf der auch ein Materialrand 101 mehr oder weniger senkrecht zur Ebene E des platten- oder streifenförmigen Materials 1, 1' vorsteht. Dieser in der Regel umlaufende Materialrand 101 ist stoffschlüssig mit dem platten- oder streifenförmigen Material 1, 1' verbunden und entsteht während des nachfolgend noch erörterten Herstellungsprozesses durch Verformung eines Materialabschnittes des platten- oder streifenförmigen Materials 1, 1'. Dieser Materialrand 101 liegt also unter Vorspannung am Außenumfang 9' des Einpressbolzens 5 unter fester Vorspannung an, wodurch der gewünschte Presssitz 13 realisiert wird.As mentioned, so ultimately comes the
Wie nicht näher gezeigt ist, kann aber auch die Unterseite oder Basis 8 des Einpressbolzens 5 lötfähig sein (wenn beispielsweise der Einpressbolzen 5 aus einem gut lötfähigen Material besteht oder mit einem gut lötfähigen Material überzogen ist) oder weist zumindest an seiner Unter- oder Basisseite 8 alternativ oder ergänzend zu dem lötfähigen Bolzenkopf 7 eine lötfähige, d.h. also gut lötfähige Fläche LF auf. Schließlich wird schon an dieser Stelle der Vollständigkeit halber erwähnt, dass der Einpressbolzen nicht so in dem platten- oder streifenförmigen Material 1, 1' unter Ausbildung einer Durchtrittsöffnung 14 eingearbeitet sein muss, dass seine Unter- oder Basisseite 8 mit der Unterseite 1b des platten- oder streifenförmigen Materials 1, 1' fluchten muss. Vielmehr wäre es auch möglich, dass die Unter- oder Basisseite 8 über die Ebene E des platten- oder streifenförmigen Materials 1, 1' auch weiter nach unten übersteht. Dass der Einpressbolzen soweit eingeschoben wird, dass seine Unter- oder Basisseite 8 oberhalb der Ebene E des platten- oder streifenförmigen Materials 1, 1' zu liegen kommt, in welchem der Einpressbolzen noch von dem Materialrand 101 gehalten werden kann, ist eher unerwünscht, da dann die Presskräfte zwischen Materialrand 101 und dem Außenumfang 9' des Bolzenkörpers abnehmen.As not shown in detail, but also the bottom or

Dazu wird ein Presswerkzeug 21 mit einem oben liegenden Stempel 23 verwendet, der im gezeigten Ausführungsbeispiel zylinderförmig gestaltet ist und von einem rohrförmigen äußeren Stempel oder Niederhalter 25 umgeben ist. Unterhalb ist ferner eine rohrförmige Matrize 27 angeordnet, also eine Matrize 27 mit einer zentralen Ausnehmung 27a.For this purpose, a

Um ein kraterförmiges Aufreißen des mit dem Bolzenkörper 9, d.h. dem Außenumfang 9' des Einpressbolzens 5 wechselwirkenden Materialrand 101 zu vermeiden, wird bevorzugt vor dem Einpressen des Einpressbolzens eine entsprechende Zentrieröffnung oder Zentrierbohrung an der Stelle in das platten- oder streifenförmige Material 1, 1' eingebracht, an der der Einpressbolzen 5 eingepresst werden soll. Dabei soll die Öffnung in dem platten- oder streifenförmigen Material 1, 1' bevorzugt einen Durchmesser aufweisen, der größer ist als der gegebenenfalls vorlaufende bevorzugt flach ausgebildete Kopf 7. Mit anderen Worten soll der Einpressbolzen so ausgebildet sein, dass er bereits in einem Durchmesserbereich mit einer konischen oder schulterförmig abfallenden Flanke 11 in die vorgestanzte oder voreingebrachte Öffnung im Material 1, 1' eingreift. Von daher sind alle Abschnitte, bei denen der Einpressbolzen 5 von einem kleineren Durchmesser zu einem größeren Durchmesser übergeht, vorzugsweise in Einpressrichtung R (
Insbesondere dann, wenn im Bereich des Presssitzes 13 der Bolzenkörper 9 mit der umlaufenden Rändelung 15 versehen ist, ergibt sich ein besonders fester und intensiver, eine gute elektrische Verbindung erzeugender Presssitz zwischen dem Bolzenkörper 9 und dem elektrisch nicht leitfähigen Material 1.In particular, when in the region of the
Um also die Verformung des Materials 1, 1' zu verbessern und eine ausgerissene Kraterbildung im Bereich des umgelegten Materialrandes 101 zu vermeiden, wird an der betreffenden Stelle, an der der Bolzenkörper 9 in das Material 1, 1' eingepresst wird, das Material zuvor vorgelocht, wobei die Größe dieser Vorlochung materialabhängig optimiert werden kann. Die Flächen des Bolzenkörpers 9 sind dabei zumindest in Axialrichtung abschnittsweise konisch oder leicht konisch, insbesondere durch die Ausbildung der erwähnten Schultern 11 und/oder der Rippen 15a.Thus, in order to improve the deformation of the

Sofern das platten- oder streifenförmige Material 1 vor dem Einbringen des Einpressbolzens 5 noch erwärmt wird, kann bei der nachfolgenden Kühlung noch ein zusätzlicher Schrumpfeffekt im Material 1, 1' dazu beitragen, dass der umgelegte Materialrand 101 mit noch höherer Presswirkung am Außenumfang des Bolzenkörpers 9 im Bereich seines Presssitzes 13 anliegt. Ebenso könnte alternativ oder zusätzlich vor dem Einbringen des Einpressbolzens der Einpressbolzen 5 abgekühlt werden, so dass der Presssitz nach dem Einbringen des Einpressbolzens 5 in das Material 1, 1' dadurch verbessert wird, dass das Material des Einpressbolzens 5 durch den Ausdehnungsprozess des Einpressbolzens ebenfalls verbessert wird.If the plate-like or strip-shaped

Im Rahmen der Erfindung können unterschiedlichste streifen- oder plattenförmige Leiter 1, 1' verwendet werden. Auch der Dickenbereich dieser streifen- oder plattenförmigen Leiter 1, 1' kann in weiten Bereichen unterschiedlich gewählt werden, so lange eine entsprechende Verarbeitung im Rahmen der Erfindung möglich ist. Insbesondere kann der Einpressbolzen 13 bei Leitern 1 verwendet werden, die eine Dicke aufweisen, die bis 5 mm, 6 mm, 8 mm, 9 mm oder sogar 10 mm reicht. Platten mit einem Dickenbereich unter 4 mm, insbesondere unter 3 mm, 2 mm sind ebenfalls möglich.In the context of the invention, a wide variety of strip or plate-shaped
Die Erfindung kann aber ebenso bei sehr dünnen, blechförmigen Leitern und Platten verwendet werden, beispielsweise bei Platten in Form von Blechen, die eine Dicke von 0,4 mm und mehr aufweisen, insbesondere eine Dicke von zumindest 0,5 mm, 0,6 mm, 0,7 mm, 0,8 mm, 0,9 mm oder 1 mm aufweisen. Somit lässt sich die Erfindung vor allem auch in Bereichen von nicht nur 0,4 mm, sondern insbesondere von etwa 1 mm bis 2 mm Platten- oder Blechdicke optimal umsetzen. Dabei kommen alle elektrisch leitfähigen platten- oder streifenleiterförmigen Platten oder Bleche in Betracht, die beispielsweise in einem Walzverfahren hergestellt sind, die als Druckgussteil hergestellt sind, die aus einem Strangpressteil bestehen oder die durch andere Bearbeitungsschritte einschließlich Sägen, Stanzen und Verformen hergestellt sind. Einschränkungen bestehen insoweit nicht.However, the invention can also be used with very thin, sheet-like conductors and plates, for example in the form of sheets in the form of sheets, which have a thickness of 0.4 mm and more, in particular a thickness of at least 0.5 mm, 0.6 mm , 0.7 mm, 0.8 mm, 0.9 mm or 1 mm. Thus, the invention can be optimally implemented especially in areas of not only 0.4 mm, but in particular from about 1 mm to 2 mm plate or sheet thickness. In this case, all electrically conductive plate or strip conductor-shaped plates or sheets into consideration, which are for example produced in a rolling process, which are made as a die-cast part, which consist of an extrusion or which are made by other processing steps including sawing, punching and deformation. There are no restrictions in this respect.
Der Einpressbolzen kann aus allen geeigneten Materialien bestehen. Insbesondere eignen sich hierfür Materialien wie Messing, Kupfer, Bronze.The press-fit bolt can consist of all suitable materials. In particular, materials such as brass, copper, bronze are suitable for this purpose.
Aus der Beschreibung und den Zeichnungen geht also hervor, dass der Einpressbolzen 5 einen Bolzenkopf 7 aufweist, der einen deutlich kleineren Durchmesser aufweist als der umlaufende Mantel, also einen kleineren Durchmesser aufweist als die umlaufende Oberfläche des Bolzenkörpers 9. Dabei kann der umlaufende Mantel oder die umlaufende Oberfläche des Bolzenkörpers 9 glatt oder mit einer Rändelung versehen sein, die dann noch weiter radial über den Durchmesser des Bolzenkopfs 7 übersteht. Hierdurch wird ein bevorzugt kontinuierlicher Übergang vom Bolzenkopf 7 über zunehmend breiter werdende, flankenförmige Schultern 11 in den eigentlichen Bolzenkörper 9 realisiert. Dadurch wird es möglich, dass das entsprechende Plattenmaterial beim Durchdringen des Einpressbolzens 5 durch die Wechselwirkung mit der zunehmend breiter werdenden und flankenförmig ausgestalteten Schulter verformt wird, und zwar unter Ausbildung eines quer zum Plattenmaterial überstehenden Materialrandes 101. Der umgebördelte Materialrand 101 (das heißt der umgebördelte Materialrand 101 in seiner gesamten Höhe einschließlich der Dicke des platten- oder streifenförmigen Materials 1, 1') kann dabei eine Höhe aufweisen, die größer ist als das 1,1-, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 1,9-, 2,0-, 2,1-, 2,2-, 2,3-, 2,4-, 2,5-, 2,6-, 2,7-, 2,8-, 2,9-, 3,0-fache der Dicke des platten- oder streifenförmigen Materials 1, 1'. Mit anderen Worten ist eine Ausgestaltung in der Regel günstig und ausreichend, wenn die Gesamthöhe des umgebördelten Materialrandes 101 (einschließlich der Stärke des platten- und streifenförmigen Materials) nicht größer ist als das 3,0-, 2,9-, 2,8-, 2,7-, 2,6-, 2,5-, 2,4-, 2,3-, 2,2-, 2,1-, 2,0-, 1,9-, 1,8-, 1,7-, 1,6-, 1,5-fache der Stärke des platten-, bzw. streifenförmigen Materials 1, 1'.It therefore appears from the description and the drawings that the press-in
Der Einpressbolzen 5 kann ebenfalls in weiten Bereichen mit unterschiedlichen Bemaßungen ausgebildet sein.The press-in
Vorzugsweise ist der Einpressbolzen 5 so dimensioniert, dass der Durchmesser im Bereich seines Bolzenkörpers 9 beispielsweise zwischen 1,5 mm bis 7 mm liegt, vorzugsweise einen Durchmesser aufweist, der größer ist als 2,0 mm, 2,5 mm, 3,0 mm, 3,25 mm, 3, 5 mm, 3,75 mm, 4,0 mm, 4,25 mm, 4,5 mm, 4,75 mm oder größer ist als 5,0 mm. Ferner ist es für viele Anwendungsfälle ausreichend, wenn der Außendurchmesser des Bolzenkörpers 9 nicht größer ist als 8,0 mm, insbesondere kleiner ist als 7,5 mm, 7,0 mm, 6,5 mm, 5,0 mm, 4,75 mm, 4,5 mm, 4,25 mm, 4,0 mm, 3,75 mm, 3, 5 mm und insbesondere kleiner als 3,0 mm.Preferably, the press-in
Die axiale Länge oder Höhe des Einpressbolzens 5 kann ebenfalls in weiten Bereichen unterschiedlich gewählt werden. Bevorzugt beträgt die axiale Länge des Einpressbolzens 5 ein Maß, das zumindest der 1,5-fachen Dicke des platten- oder streifenförmigen Materials 1, 1' entspricht. Vorzugsweise ist die axiale Höhe des Einpressbolzens 5 zumindest 2-, 3-, 4-, 4,5- oder ungefähr 5-fach so groß wie die Dicke des platten- oder streifenförmigen Materials 1, 1'. Andererseits ist es in der Regel ausreichend, wenn die axiale Länge oder Höhe des Einpressbolzens 5 nicht größer ist als die 10-fache Dicke des platten- oder streifenförmigen Materials 1, 1', insbesondere nicht höher ist als die 9-, 7-, 6- oder 6,5-fache Dicke des platten- oder streifenförmigen Materials 1, 1'.The axial length or height of
Auch das Verhältnis zwischen dem Durchmesser des Bolzenkörpers 9 (im Bereich seines Presssitzes) und dem Durchmesser des Bolzenkopfes 7 kann ebenfalls unterschiedlich gewählt werden. In vielen Fällen ist es ausreichend, wenn der maximale Durchmesser des im platten- oder streifenförmigen Material 1, 1' eingepressten Teils des Bolzenkörpers 9 um mindestens 10%, vorzugsweise um zumindest 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 110%, 120%, 130%, 140% oder sogar um 150% größer ist als der Durchmesser des Bolzenkopfes 7. Umgekehrt ist es in der Regel ausreichend, wenn der maximale Durchmesser des Bolzenkörpers 9 im Bereich seines Presssitzes um weniger als 200% größer ist als der Durchmesser des Bolzenkopfes 7, insbesondere also um weniger als 180%, 160%, 150%, 140%, 130%, 120%, 110%, 100%, 90% oder weniger als 80%.
