- an electrical circuit board having a plurality of spaced apart pins which protrude perpendicularly from the circuit board and are each electrically connected to a connecting wire.
- the lead wire is wound around the lead pin, wherein the electrical contact between pin and wire is made in wire-wrap connection technology, in which the lead wire is wrapped around the pin with such a strong longitudinal pull that a sharp corner on the lead pin with the lead wire cold-welded, electrically conductive compound enters.
- From the DE 28 23 039 A1 is an electrical contact between the winding of a coil core and a copper wire known, wherein the winding is made of a copper wire, which is provided with an insulating paint layer.
- the wound on the lead wire end of the winding is contacted by a crimped sheath with the lead wire.
- the surface structure of the shell inside is chosen so that the crushed shell cuts through the lacquer layer of the winding wire.
- the invention is based on the object of providing an electrically conductive connection between a connecting pin and a connecting wire with simple measures and without supplying heat.
- the electrically conductive connection between the connecting pin and the connecting wire which is provided with an electrical insulation, in that the connecting wire including insulating jacket, so without removing the insulation, is wound around the connecting pin, which is an edge has, so that the wire winding is applied directly to this edge.
- a Anpressteil is provided, which surrounds the connecting pin in the region of the wire winding and exerts a radial contact force on the wire winding, wherein the radial contact pressure is directed inwardly in the direction of the connecting pin.
- the wire winding is acted upon by a radially outwardly inwardly directed contact force and pressed against the edge on the outer jacket of the terminal pin, whereby the insulating jacket is injured and the conductive core in the wire comes into direct contact with the conductive pin.
- a cold welding between the wire and the lateral surface of the pin in the region of the contact points is achieved due to the continuing, high contact pressure.
- a sufficiently high contact normal force is generated by the pressing part, which ensures the electrically conductive contact between the wire and the pin.
- a second aspect of the invention which relates to the method for producing the electrically conductive connection, first the connecting wire including the electrical insulating jacket is wound around the edge on the connecting pin, then the pressing part is placed around the wire winding on the connecting pin and it is about this Anpressteil a generated radially in the direction of the pin acting pressing force. This is done in such a way that the pressing part is pushed axially onto the connecting pin, wherein the wire winding can already be pressed radially against the connecting pin during the pushing on. It is expedient that the wire winding is displaced axially during pushing, so that the sharp edge on the connecting pin cuts through the insulating jacket. By this cutting movement of the insulating jacket is severed, so that the wire passes into direct contact with the lateral surface at the edge of the pin.
- the Anpressteil executed in such a way that with the pushing of the pressing already the radial pressure is exerted expediently at least a portion of the Anpressteils, which is preferably designed as a sleeve, an inner diameter which is less than at least a portion of the order Pin laid wire winding, so that already by pushing on the pressure sleeve, the radial contact force is generated.
- This can still be supported by a conical internal geometry of the pressing, which on the one hand allows for easier placement of the Anpressteils on the front side of the pin and on the other automatically causes an increased radial contact pressure with increasing axial sliding.

- the connecting wire 3 has an insulating jacket 7, which is expediently designed as an insulating lacquer layer in coil wire and is injured or severed by the radial contact pressure in the region of the relatively sharp edges 5.
- the contact pressure generated by the Anpressteil 6 is high enough that the insulating jacket 7 is severed and the edges 5 protrude into the core of the lead wire 3.

- the methods described for the non-slotted sleeve for making the electrical contact are also applicable to the slotted sleeve.
- the dimensioning and the shape of the Anpress presses 6 is chosen so that they produce without a radial contact force on the pin including the wire winding. 4 can be deferred.
- the radial contact force is achieved only after reaching the final axial position in that the pressing member 6 is mechanically compressed and pressed against the pin and the wire winding 4.

Die Erfindung bezieht sich auf einen elektrischen Kontakt zwischen einem Anschlussstift und einem zu verbindenden Anschlussdraht nach dem Oberbegriff des Anspruches 1 sowie auf ein Verfahren zur Herstellung einer elektrischen Verbindung zwischen einem Anschlussstift und einem Anschlussdraht nach Anspruch 11.The invention relates to an electrical contact between a connecting pin and a connecting wire to be connected according to the preamble of

Voraussetzung für die Durchführung des Wire-Wrap-Verfahrens ist jedoch die vorherige Abisolierung des Anschlussdrahtes sowie der Einsatz spezieller Wickelwerkzeuge, mit denen der Anschlussdraht mit der erforderlichen Zugspannung um den Anschlussstift gewickelt wird.Prerequisite for the implementation of the wire-wrap method, however, is the previous stripping of the connecting wire and the use of special winding tools with which the Connecting wire with the required tension around the pin is wound.

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, mit einfachen Maßnahmen und ohne Wärmezufuhr eine elektrisch leitende Verbindung zwischen einem Anschlussstift und einem Anschlussdraht zu schaffen.Based on this state of the art, the invention is based on the object of providing an electrically conductive connection between a connecting pin and a connecting wire with simple measures and without supplying heat.
Diese Aufgabe wird erfindungsgemäß bei einem elektrischen Kontakt zwischen Anschlussstift und Anschlussdraht mit den Merkmalen des Anspruches 1 und bei einem Verfahren zur Herstellung einer elektrischen Verbindung zwischen Anschlussstift und Anschlussdraht mit den Merkmalen des Anspruches 9 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved in an electrical contact between pin and lead wire with the features of
Gemäß eines ersten Aspektes der Erfindung erfolgt die elektrisch leitfähige Verbindung zwischen dem Anschlussstift und dem Anschlussdraht, der mit einer elektrischen Isolierung versehen ist, dadurch, dass der Anschlussdraht einschließlich Isoliermantel, also ohne die Isolation zu entfernen, um den Anschlussstift gewickelt ist, der eine Kante aufweist, so dass die Drahtwicklung unmittelbar an dieser Kante anliegt. Des Weiteren ist ein Anpressteil vorgesehen, welches den Anschlussstift im Bereich der Drahtwicklung umgreift und eine radiale Anpresskraft auf die Drahtwicklung ausübt, wobei die radiale Anpresskraft nach innen in Richtung auf den Anschlussstift gerichtet ist. Auf diese Weise wird die Drahtwicklung mit einer radial von außen nach innen gerichteten Anpresskraft beaufschlagt und auf die Kante am Außenmantel des Anschlussstiftes angedrückt, wodurch der Isoliermantel verletzt wird und der leitfähige Kern im Draht in unmittelbaren Kontakt mit dem leitfähigen Anschlussstift gelangt. Gegebenenfalls wird aufgrund des fortdauernden, hohen Anpressdruckes eine Kaltverschweißung zwischen dem Draht und der Mantelfläche des Stiftes im Bereich der Kontaktstellen erreicht. Über das Anpressteil wird über die Lebensdauer des Produktes eine ausreichend hohe Kontaktnormalkraft erzeugt, die den elektrisch leitfähigen Kontakt zwischen Draht und Stift sicherstellt.According to a first aspect of the invention, the electrically conductive connection between the connecting pin and the connecting wire, which is provided with an electrical insulation, in that the connecting wire including insulating jacket, so without removing the insulation, is wound around the connecting pin, which is an edge has, so that the wire winding is applied directly to this edge. Furthermore, a Anpressteil is provided, which surrounds the connecting pin in the region of the wire winding and exerts a radial contact force on the wire winding, wherein the radial contact pressure is directed inwardly in the direction of the connecting pin. In this way, the wire winding is acted upon by a radially outwardly inwardly directed contact force and pressed against the edge on the outer jacket of the terminal pin, whereby the insulating jacket is injured and the conductive core in the wire comes into direct contact with the conductive pin. Optionally, a cold welding between the wire and the lateral surface of the pin in the region of the contact points is achieved due to the continuing, high contact pressure. Over the life of the product, a sufficiently high contact normal force is generated by the pressing part, which ensures the electrically conductive contact between the wire and the pin.
Gemäß eines zweiten Aspektes der Erfindung, der das Verfahren zur Herstellung der elektrisch leitfähigen Verbindung betrifft, wird zunächst der Anschlussdraht einschließlich des elektrischen Isoliermantels um die Kante am Anschlussstift gewickelt, anschließend wird das Anpressteil um die Drahtwicklung am Anschlussstift gelegt und es wird über dieses Anpressteil eine radial in Richtung auf den Anschlussstift wirkende Anpresskraft erzeugt. Dies erfolgt in der Weise, dass das Anpressteil axial auf den Anschlussstift aufgeschoben wird, wobei bereits während des Aufschiebens die Drahtwicklung radial gegen den Anschlussstift gepresst werden kann. Hierbei ist es zweckmäßig, dass die Drahtwicklung während des Aufschiebens axial verschoben wird, so dass die scharfe Kante am Anschlussstift den Isoliermantel durchschneidet. Durch diese Schneidebewegung wird der Isoliermantel durchtrennt, so dass der Draht in unmittelbaren Kontakt mit der Mantelfläche an der Kante des Stiftes gelangt.According to a second aspect of the invention, which relates to the method for producing the electrically conductive connection, first the connecting wire including the electrical insulating jacket is wound around the edge on the connecting pin, then the pressing part is placed around the wire winding on the connecting pin and it is about this Anpressteil a generated radially in the direction of the pin acting pressing force. This is done in such a way that the pressing part is pushed axially onto the connecting pin, wherein the wire winding can already be pressed radially against the connecting pin during the pushing on. It is expedient that the wire winding is displaced axially during pushing, so that the sharp edge on the connecting pin cuts through the insulating jacket. By this cutting movement of the insulating jacket is severed, so that the wire passes into direct contact with the lateral surface at the edge of the pin.
Ist das Anpressteil in der Weise ausgeführt, dass mit dem Aufschieben des Anpressteils bereits der radiale Druck ausgeübt wird, weist zweckmäßig zumindest ein Abschnitt des Anpressteils, das bevorzugt als Hülse ausgebildet ist, einen Innendurchmesser auf, der geringer ist als wenigstens ein Abschnitt der um den Stift gelegten Drahtwicklung, so dass bereits durch das Aufschieben der Anpresshülse die radiale Anpresskraft erzeugt wird. Dies kann noch durch eine konische Innengeometrie des Anpressteils unterstützt werden, welche zum einen ein erleichtertes Aufsetzen des Anpressteils auf die Stirnseite des Stiftes ermöglicht und zum andern mit zunehmendem axialen Aufschieben automatisch eine erhöhte radiale Anpressung bewirkt. Die Konusform hat zudem den Vorteil, dass das Maß des axialen Aufschiebens die Höhe der radialen Anpresskraft bestimmt.Is the Anpressteil executed in such a way that with the pushing of the pressing already the radial pressure is exerted expediently at least a portion of the Anpressteils, which is preferably designed as a sleeve, an inner diameter which is less than at least a portion of the order Pin laid wire winding, so that already by pushing on the pressure sleeve, the radial contact force is generated. This can still be supported by a conical internal geometry of the pressing, which on the one hand allows for easier placement of the Anpressteils on the front side of the pin and on the other automatically causes an increased radial contact pressure with increasing axial sliding. The cone shape also has the advantage that the degree of axial pushing determines the height of the radial contact pressure.
Als weitere Alternative kommt eine in Längsrichtung geschlitzte Hülse in Betracht, die sich aufgrund ihrer Federwirkung radial öffnen lässt und dann einen radial nach innen gerichteten Druck ausübt.Another alternative is a longitudinally slotted sleeve into consideration, which can be opened radially due to their spring action and then exerts a radially inwardly directed pressure.
Gemäß einer weiteren vorteilhaften Ausführung ist das Anpressteil auch topfförmig ausgebildet, d.h. es ist ein Boden vorgesehen, der das Aufschieben des Anpressteils auf die Stirnseite des Stiftes begrenzt.According to a further advantageous embodiment, the Anpressteil is also pot-shaped, ie it is provided a bottom which limits the pushing of the pressing on the end face of the pin.
Um Reibungskräfte zu vermindern, die beim Aufschieben des Anpressteils zwischen der Innenwand des Anpressteils und dem Isoliermantel auftreten können, welcher den Anschlussdraht umgibt, kann es vorteilhaft sein, die Innenwand des Anpressteils mit einer reibungsmindernden Beschichtung zu versehen. Möglich ist auch der Einsatz eines Schmiermittel, insbesondere auf organischer Basis.In order to reduce frictional forces which may occur when the pressing part is pushed between the inner wall of the pressing part and the insulating jacket which surrounds the connecting wire, it may be advantageous to provide the inner wall of the pressing part with a friction-reducing coating. It is also possible to use a lubricant, especially on an organic basis.

- a section through the pin including wire winding and attached Anpressteil.
Bei dem in den Figuren dargestellten Ausführungsbeispiel handelt es sich um einen Anschlussstift 1, der aus elektrisch leitfähigem Material besteht und Bestandteil eines elektrischen Bauteiles 2 ist, beispielsweise eines Wicklungsträgers oder dergleichen und elektrisch mit einem Anschlussdraht 3 zu verbinden ist, der von einer nicht dargestellten Spulenwicklung abzweigt. Der elektrische Anschlussdraht 3 ist einschließlich seines Isoliermantels um die Mantelfläche des Anschlussstiftes 1 gelegt und bildet eine Drahtwicklung 4. Um einen elektrischen Kontakt zwischen dem Anschlussdraht und dem Anschussstift 1 herzustellen und auch über die Lebensdauer des Bauteils einen dauerhaften Kontakt sicherzustellen, wird der Kern des Anschlussdrahtes 3 ohne Zusatz von Wärme dauerhaft auf den Anschlussstift 1 gepresst. Dabei kann es auch zur Kaltverschweißung kommen. Der Anschlussstift 1 besitzt einen rechteckförmigen, insbesondere einen quadratischen Querschnitt und weist insgesamt vier scharfe Kanten 5 auf, an denen der Kern des Anschlussdrahtes 3 in elektrisch leitendem Kontakt anliegt.In the embodiment shown in the figures is a
Dieser elektrische Kontakt wird durch mechanisches Fügen hergestellt. Hierzu wird ein hülsenförmiges und konisch ausgebildetes Anpressteil 6 axial auf die Stirnseite des Anschlussstiftes 1 unter Druck oder Zug aufgesetzt. Während des axialen Aufschiebens des Anpressteiles 6 übt dieses aufgrund seiner Konusform einen zunehmenden, radial nach innen gerichteten Anpressdruck auf die Drahtwicklung 4 aus, so dass diese gegen die Mantelfläche und insbesondere gegen die Kanten 5 des Anschlussstiftes gedrückt wird. Der Anschlussdraht 3 besitzt einen Isoliermantel 7, der bei Spulendraht zweckmäßig als isolierende Lackschicht ausgeführt ist und durch den radialen Anpressdruck im Bereich der verhältnismäßig scharfen Kanten 5 verletzt bzw. durchtrennt wird. Die von dem Anpressteil 6 erzeugte Anpresskraft ist hoch genug, dass der Isoliermantel 7 durchtrennt wird und die Kanten 5 bis in den Kern des Anschlussdrahtes 3 einragen. Aufgrund des andauernden, von dem Anpressteil 6 erzeugten Druckes entsteht zwischen den Kanten 5 des Anschlussstiftes 1 und dem Kern des Anschlussdrahts 3 eine dauerhafte elektrische Verbindung. Hierbei kann es zweckmäßig sein, Anpressteil 6 und Anschlusspin 1 in der Weise zu wählen, dass mit dem Aufschieben des Anpressteils die Drahtwicklung 4 zumindest teilweise axial verschoben wird, wobei diese Verschiebebewegung ein Durchschneiden des Isoliermantels 7 entlang der Kante 5 zur Folge hat. Die axiale Verschiebung der Drahtwicklung 4 entlang der Mantelfläche des Anschlussstiftes 1 kann durch einen Anschlag am Anschlussstift, beispielsweise eine umlaufende Schulter oder dergleichen, begrenzt sein.This electrical contact is made by mechanical joining. For this purpose, a sleeve-shaped and conically
Als weitere Alternative kann eine Hülse mit Längsschlitz vorgesehen sein. Der Vorteil der geschlitzten Hülse liegt darin, dass die Hülse über einen größeren Bereich an Innendurchmessern eine radiale Druckkraft ausüben kann als eine ungeschlitzte Hülse, weil die geschlitzte Hülse eine geringere Steifigkeit besitzt. Die maximale radiale Druckkraft ist jedoch bei der nicht-geschlitzten Hülse größer.As a further alternative, a sleeve can be provided with a longitudinal slot. The advantage of the slotted sleeve is that the sleeve can exert a radial compressive force over a greater range of internal diameters than an unslotted sleeve because the slotted sleeve has lower rigidity. However, the maximum radial compressive force is greater in the non-slotted sleeve.
Bei dem Verfahren zur Herstellung einer elektrischen Verbindung zwischen dem Anschlussstift und dem Anschlussdraht wird die geschlitzte Hülse im elastisch federnden Bereich aufgebogen, lose über die Drahtwicklung geschoben und dann teilweise entspannt, so dass die Hülse den Draht radial auf die Kanten des Anschlusspins presst.In the method of making an electrical connection between the terminal pin and the lead wire, the slotted sleeve is bent in the resilient portion, loosely slipped over the wire coil and then partially relaxed so that the sleeve radially presses the wire onto the edges of the terminal pin.
Grundsätzlich sind die für die nicht-geschlitzte Hülse beschriebenen Verfahren zur Herstellung des elektrischen Kontakts auch mit der geschlitzten Hülse anwendbar.In principle, the methods described for the non-slotted sleeve for making the electrical contact are also applicable to the slotted sleeve.
Gemäß einer weiteren alternativen Ausführung ist vorgesehen, dass die Dimensionierung und die Form des Anpressteiles 6 so gewählt wird, dass diese ohne eine radiale Anpresskraft zu erzeugen auf den Stift einschließlich der Drahtwicklung 4 aufgeschoben werden kann. Die radiale Anpresskraft wird erst nach dem Erreichen der endgültigen axialen Position dadurch erreicht, dass das Anpressteil 6 mechanisch verpresst und gegen den Anschlussstift sowie die Drahtwicklung 4 gedrückt wird.According to a further alternative embodiment, it is provided that the dimensioning and the shape of the
Im Rahmen der Erfindung kommen alle möglichen Querschnittsformen für den Anschlussstift 1 in Betracht, wobei ggf. die Gestalt des Anpressteils 6 auf die Querschnittsform des Anschlussstiftes 1 anzupassen ist.In the context of the invention, all possible cross-sectional shapes for the
Um das Anpressteil 6 fest und dauerhaft am Anschlussstift zu sichern, kann es zweckmäßig sein, eine Fixierung zum Stift am unteren Rand des Anpressteils, also an dem der Stirnseite des Stiftes abgewandten Rand vorzusehen.In order to secure the
