Description

Verfahren zum elektrischen Kontaktieren von StanzgitternMethod for electrically contacting punched gratings
Die Erfindung betrifft ein Verfahren zum Kontaktieren von elektrisch leitenden Stanzgittern, wobei mindestens ein erstes und ein zweites Stanzgitter an mindestens einer Stelle miteinander in elektrischen Kontakt gebracht werden. Ferner betrifft die Erfindung eine Anord¬ nung von mindestens zwei elektrisch leitenden Stanzgittern.The invention relates to a method for contacting electrically conductive stamped gratings, wherein at least a first and a second stamped grid are brought into electrical contact with each other at at least one location. Furthermore, the invention relates to an arrangement of at least two electrically conductive stamped gratings.
Stand der TechnikState of the art
Stanzgitter sind aus dem Stand der Technik bekannt. Sie werden in den Bereichen eines elektrischen Netzwerkes eingesetzt, insbeson¬ dere in einem Kraftfahrzeug, in denen leitende Elemente und Leiter- bahnen mit einer hohen Stromtragfähigkeit und einer ausreichenden Eigenstabilität benötigt werden. Die Grundlage bei der Herstellung eines Stanzgitters stellt ein flächenförmiges Ausgangsmaterial dar, beispielsweise ein Blech, insbesondere ein Kupferblech, aus dem mittels formgebenden Verfahren, insbesondere Stanzen und/oder Biegen, die elektrischen Bahnen und Anschlüsse ausgebildet wer¬ den. Dem Fachmann ist bekannt, dass ein Stanzgitter (punch grid) nicht als ein Gitter im engen Wortsinne verstanden werden muss, sondern dass vielmehr auch einfachste Geometrien wie beispiels¬ weise eine streifenförmige Leiterbahn unter diesen Begriff fallen.Punching grids are known from the prior art. They are used in the areas of an electrical network, in particular in a motor vehicle, in which conductive elements and printed conductors with a high current carrying capacity and a sufficient intrinsic stability are required. The basis for producing a stamped grid is a sheet-like starting material, for example a sheet metal, in particular a copper sheet, from which the electrical paths and connections are formed by means of shaping processes, in particular stamping and / or bending. It is known to the person skilled in the art that a punch grid does not have to be understood as a grid in the narrower sense of the word, but rather that even the simplest geometries, such as a strip-shaped conductor track, fall under this term.
Bei dem Aufbau eines elektrischen Netzwerkes kann es erforderlich sein, eine Stanzgitteranordnung, die später auf einem Potenzial lie¬ gen soll, mittels zweier oder mehrerer Stanzgitter auszubilden, die durch Punktschweißen oder Nieten mechanisch und elektrisch ver¬ bunden werden. Es hat sich jedoch als nachteilig herausgestellt, dass hierfür neben den für die Herstellung der Stanzgitter erforderli¬ chen formgebenden Verfahren zusätzliche Verbindungsverfahren, einschließlich der dafür benötigten Maschinen, erforderlich sind.In the construction of an electrical network, it may be necessary to form a stamped grid arrangement, which is later to lie on a potential, by means of two or more stamped gratings which mechanically and electrically connected by spot welding or riveting. However, it has proved to be disadvantageous that, in addition to the shaping processes required for the production of the stamped grid, additional joining methods, including the machines required for this purpose, are required for this purpose.
Vorteile der ErfindungAdvantages of the invention
Erfindungsgemäß wird zur elektrischen Kontaktierung von elektrisch leitenden Stanzgittern an einem ersten Stanzgitter eine Kontaktzun¬ ge und an einem zweiten Stanzgitter mindestens eine Ausnehmung mit mindestens einer Kontaktzone ausgebildet, und die Kontaktzunge wird in die Ausnehmung so eingesteckt, dass zumindest mittels der Kontaktzone eine elektrische Verbindung zwischen erstem und zwei- tem Stanzgitter hergestellt wird. Dies bedeutet, dass die elektrische Kontaktierung der beiden Stanzgitter kein zusätzliches Verbindungs¬ verfahren benötigt. Vielmehr erlaubt es die besondere Anfertigung von erstem und zweitem Stanzgitter, dass zur elektrischen Kontaktie¬ rung lediglich die Kontaktzunge in die Ausnehmung eingesteckt wer- den muss. Da keine weiteren Maschinen beziehungsweise Werk¬ zeuge benötigt werden, wie dies beispielsweise beim Punktschwei¬ ßen oder Nieten der Fall wäre, verringern sich die Herstellungskos¬ ten. Zudem bietet das aufgezeigte Verfahren den Vorteil, dass sich die Verbindung zwischen den Stanzgittern auf einfache Weise zer- störungsfrei wieder lösen lässt. Zum Trennen der Stanzgitter muss lediglich die Kontaktzunge aus der Ausnehmung herausgezogen werden. Insbesondere ermöglicht das erfindungsgemäße Verfahren ein mehrfaches Verbinden und Trennen der beiden Stanzgitter durch Ein- beziehungsweise Ausstecken der Kontaktzunge. Es sei ange- merkt, dass die Form der Kontaktzone je nach den bestehenden An¬ forderungen in unterschiedlichen Formen gefertigt werden kann. So kann die Kontaktzone im Wesentlichen punktförmig, linienförmig oder flächenförmig sein. Außerdem kann sich die Kontaktzone auch aus mehreren Kontaktbereichen zusammensetzen, beispielsweise an gegenüberliegenden Seiten der Ausnehmung. Die vorgeschlagene Kontaktierung von Stanzgittern lässt sich dabei besonders vorteilhaft in der Zentralelektrik eines Kraftfahrzeugs einsetzen. Dort werden Stanzgitter verwendet, um elektrische Verbindungen zwischen Lei- terplatten, Steckern und auswechselbaren Elementen, wie zum Bei¬ spiel Sicherungen oder Relais herzustellen. Für Details zur Zentral¬ elektrik eines Kraftfahrzeugs wird auf DE 100 21 217 C1 verwiesen.According to the invention, at least one recess with at least one contact zone is formed on a first stamped grid for electrical contacting of electrically conductive stamped grid, and the contact tongue is inserted into the recess such that at least by means of the contact zone an electrical connection between first and second punched grid is produced. This means that the electrical contacting of the two lead frames requires no additional Verbindungs¬ procedure. On the contrary, the special production of first and second stamped grid allows that only the contact tongue has to be inserted into the recess for electrical contacting. Since no further machines or tools are required, as would be the case, for example, with spot welding or riveting, the production costs are reduced. In addition, the method shown offers the advantage that the connection between the stamped bars can be broken down in a simple manner - can be solved trouble-free again. To separate the punched grid, only the contact tongue has to be pulled out of the recess. In particular, the method according to the invention enables a multiple connection and disconnection of the two punched grids by inserting or removing the contact tongue. It should be noted that the shape of the contact zone can be manufactured in different shapes depending on the existing requirements. Thus, the contact zone may be substantially punctiform, linear or planar. In addition, the contact zone can also be composed of several contact areas, for example opposite sides of the recess. The proposed contacting of stamped gratings can be used particularly advantageously in the central electrical system of a motor vehicle. Here, punched grids are used to produce electrical connections between printed circuit boards, plugs and interchangeable elements, such as fuses or relays. For details on Zentral¬ electrics of a motor vehicle is made to DE 100 21 217 C1.
Vorteilhafterweise ist die Kontaktzunge relativ zum ersten Stanzgitter abgewinkelt, insbesondere in etwa rechtwinklig. Dies ermöglicht eine besonders flexible Anordnung der Stanzgitter zueinander, sodass sich auch besondere räumliche Verhältnisse berücksichtigen lassen.Advantageously, the contact tongue is angled relative to the first stamped grid, in particular approximately at right angles. This allows a particularly flexible arrangement of the stamped grid to each other, so that can be taken into account special spatial conditions.
Es ist vorteilhaft, wenn das erste und zweite Stanzgitter vor dem Ein- stecken der Kontaktzunge in die Ausnehmung in etwa parallel zuein¬ ander positioniert werden. Dadurch ergibt sich eine besonders platz¬ sparende Anordnung der beiden Stanzgitter, insbesondere im zu¬ sammengesteckten Zustand.It is advantageous if the first and second punched grids are positioned approximately parallel to one another prior to insertion of the contact tongue into the recess. This results in a particularly space-saving arrangement of the two stamped grid, in particular in zu¬ sammengesteckt state.
Bei einer bevorzugten Weiterbildung der Erfindung wird als Teil der Kontaktzone mindestens eine Kontaktnase einstückig mit dem zwei¬ ten Stanzgitter ausgebildet. Die Kontaktnase ist dabei insbesondere am Rand der Ausnehmung ausgebildet und weist zum Zentrum der Ausnehmung. Wird nun die Kontaktzunge in die Ausnehmung einge- steckt, so ergibt sich zumindest ein wohl definierter Kontaktpunkt.In a preferred development of the invention, as part of the contact zone, at least one contact nose is formed integrally with the second punched grid. The contact nose is formed in particular at the edge of the recess and faces the center of the recess. If now the contact tongue is inserted into the recess, then at least a well-defined contact point results.
Mit Vorteil verbiegt sich die Kontaktnase beim Einstecken der Kon¬ taktzunge teilelastisch und übt eine Druckkraft gegen die Kontakt¬ zunge aus. Teilelastisch ist dabei in dem Zusammenhang zu verste- hen, dass die Kontaktnase beim Einstecken sowohl plastisch als auch elastisch verformt wird, sodass eine - sei es auch geringe - elastische Rückstellkraft bestehen bleibt. Mittels dieser elastischen Komponente hält die Kontaktnase die Kontaktzunge sicher in ihrem Sitz. Die von der Kontaktnase auf die Kontaktzunge ausgeübte Kraft - A -Advantageously, the contact nose bends partially elastic when inserting the contact tongue and exerts a compressive force against the contact tongue. Partially elastic is to be understood in the context that the contact nose is deformed both plastically and elastically during insertion, so that a - albeit small - elastic restoring force remains. By means of this elastic component, the contact nose securely holds the contact tongue in its seat. The force exerted by the contact nose on the contact tongue force - A -
liegt in einem eng definierten, insbesondere (nahezu) punktförmigen Bereich an, sodass sich ein ausreichender Druck zum Halten der Kontaktzunge einstellt. Wird die Kontaktzunge aus der Ausnehmung herausgezogen, beispielsweise während einer Demontage, so federt die Kontaktnase um einen gewissen Betrag in Richtung ihrer ur¬ sprünglichen Position zurück, sodass auch bei einem erneuten Ein¬ stecken der Kontaktzunge der sichere Halt gewährleistet ist.lies in a narrowly defined, in particular (almost) punctiform area, so that a sufficient pressure for holding the contact tongue is established. If the contact tongue is pulled out of the recess, for example during disassembly, then the contact nose springs back by a certain amount in the direction of its original position so that the secure contact is ensured even if the contact tongue is inserted again.
Vorteilhafterweise wird im vorderen Bereich der Kontaktzunge eine Einführhilfe, insbesondere in Form einer Materialverjüngung, ausge¬ bildet. Eine derartige Einführhilfe kann beispielsweise in Form einer Spitze ausgebildet sein. Dadurch kann insbesondere eine gewünsch¬ te Verformung einer Kontaktnase erleichtert werden, als auch das Zentrieren der Kontaktzunge innerhalb der Ausnehmung.Advantageously, an insertion aid, in particular in the form of a material taper, is formed in the front region of the contact tongue. Such an insertion aid may be formed, for example in the form of a tip. As a result, in particular a desired deformation of a contact nose can be facilitated, as well as the centering of the contact tongue within the recess.
Gemäß einer vorteilhaften Weiterbildung der Erfindung wird zur Ver¬ meidung einer Kontaktierung an einem dritten Stanzgitter, welches zwischen dem ersten und zweiten Stanzgitter positioniert wird, eine Aussparung am dritten Stanzgitter derart ausgebildet, dass die Kon- taktzunge die Aussparung ohne eine Kontaktierung des dritten Stanzgitters durchtritt. Bei einer Stanzgitteranordnung mit mehreren Stanzgitterebenen wird es nicht immer erforderlich sein, dass jedes Stanzgitter zu jedem anderen Stanzgitter elektrischen Kontakt hat. Vielmehr können verschiedene Gruppen von Stanzgitter erforderlich sein, wobei die Stanzgitter einer Gruppe auf einem Potenzial liegen, welches sich von dem Potenzial einer anderen Gruppe von Stanzgit¬ tern (zumindest zeitweise) unterscheiden soll. So könnte beispiels¬ weise eine Stanzgitteranordnung ein Massepotenzial tragen, wäh¬ rend eine andere Stanzgitteranordnung ein Betriebsspannungspo- tenzial trägt. Befindet sich nun ein Stanzgitter einer Stanzgitteran¬ ordnung zwischen Stanzgittern einer anderen Stanzgitteranordnung, so lässt sich eine ungewünschte Kontaktierung mittels der vorge¬ schlagenen Aussparung auf einfache Weise vermeiden. Dies ermög¬ licht eine hohe Flexibilität bei der Anordnung von Stanzgittern. Bevorzugt wird zur Herstellung einer zusätzlichen Kontaktierung an einem dritten Stanzgitter, welches zwischen dem ersten und zweiten Stanzgitter positioniert wird, am dritten Stanzgitter eine Ausnehmung mit mindestens einer Kontaktzone ausgebildet (also zusätzlich zu der im zweiten Stanzgitter vorhandenen Ausnehmung) und die Kontakt¬ zunge durch die Ausnehmungen im zweiten und dritten Stanzgitter gesteckt. Dadurch lässt sich auf einfache Weise eine Verbindung zwischen mehreren Stanzgittern herstellen.According to an advantageous development of the invention, a recess on the third stamped grid is formed such that the contact tongue passes through the recess without contacting the third stamped grid in order to avoid contact with a third stamped grid which is positioned between the first and second stamped grid , With a leadframe arrangement with multiple punched grid levels, it will not always be necessary for each leadframe to have electrical contact with each other leadframe. Rather, different groups of leadframes may be required, with the leadframes of one group being at a potential which should be different (at least temporarily) from the potential of another group of stamped gratings. Thus, for example, a stamped grid arrangement could carry a ground potential, while another stamped grid arrangement bears an operating voltage potential. If a punched grid of a punched grid arrangement is now located between punched grids of another stamped grid arrangement, unwanted contacting by means of the proposed cutout can be avoided in a simple manner. This allows a high flexibility in the arrangement of stamped gratings. For producing an additional contact on a third punched grid which is positioned between the first and second stamped grid, a recess with at least one contact zone is preferably formed on the third stamped grid (ie in addition to the recess present in the second stamped grid) and the contact tongue through the Recesses inserted in the second and third punched grid. This makes it easy to establish a connection between a plurality of lead frames.
Mit Vorteil weist mindestens die Kontaktzone des dritten Stanzgitters eine einstückig mit dem Stanzgitter ausgebildete Kontaktnase auf, die beim Einstecken der Kontaktnase derart in Richtung des zweiten Stanzgitters gebogen wird, dass die Kontaktnase das zweite Stanz- gitter kontaktiert. Auf diese Weise, lässt sich sowohl die mechani¬ sche Stabilität der Stanzgitteranordnung als auch die Sicherheit der elektrischen Verbindung zwischen den Stanzgittern erhöhen.Advantageously, at least the contact zone of the third stamped grid has a contact nose formed integrally with the stamped grid, which is bent in the direction of the second stamped grid upon insertion of the contact nose in such a way that the contact nose contacts the second stamped grid. In this way, both the mechanical stability of the stamped grid arrangement and the safety of the electrical connection between the stamped grid can be increased.
Die Erfindung betrifft ferner eine Anordnung von mindestens zwei elektrisch leitenden Stanzgittern, wobei mindestens ein erstes und ein zweites Stanzgitter an mindestens einer Stelle elektrisch kontak¬ tiert sind, wobei das erste Stanzgitter eine Kontaktzunge aufweist, die in einer der Kontaktzunge zugeordnete, auf dem zweiten Stanz¬ gitter ausgebildete Ausnehmung mit mindestens einer Kontaktzone angeordnet ist und mindestens an der Kontaktzone anliegt. Eine der¬ artige Anordnung ermöglicht eine besonders günstige elektrische Kontaktierung von zwei Stanzgittern bei gleichzeitiger mechanischer Stabilität der Verbindung.The invention further relates to an arrangement of at least two electrically conductive stamped gratings, wherein at least one first and one second stamped grid are electrically contacted at at least one point, the first stamped grid having a contact tongue which is associated with one of the contact tongues on the second stamping ¬ lattice recess is arranged with at least one contact zone and at least applied to the contact zone. Such a arrangement enables a particularly favorable electrical contacting of two stamped gratings with simultaneous mechanical stability of the connection.
Vorteilhafterweise ist zwischen dem ersten und zweiten Stanzgitter ein drittes Stanzgitter angeordnet, welches eine Aussparung auf¬ weist, in der die Kontaktzunge ohne eine elektrische Kontaktierung angeordnet ist. Dadurch lässt sich auf einfache Weise eine Anord¬ nung mehrerer Stanzgitter realisieren, wobei die Stanzgitter (zumin- dest zu bestimmten Zeiten) unterschiedliche Potenziale tragen sol¬ len. Durch die Aussparung, also die fehlende elektrische Kontaktie- rung, kann das dritte Stanzgitter ein Potenzial tragen, welches unab¬ hängig von dem Potenzial der ersten und zweiten Stanzgitter ist.Advantageously, a third stamped grid is arranged between the first and second stamped grid, which has a recess in which the contact tongue is arranged without an electrical contact. As a result, an arrangement of several punched grids can be realized in a simple manner, wherein the stamped grids (at least at least at certain times) should carry different potentials. As a result of the recess, that is to say the lack of electrical contacting, the third stamped grid can carry a potential which is independent of the potential of the first and second stamped grid.
Bei einer bevorzugten Ausgestaltung ist zwischen erstem und drittem Stanzgitter und/oder zwischen zweitem und drittem Stanzgitter min¬ destens ein isolierendes Element, insbesondere ein Abstandshalter, angeordnet. Dadurch kann auf einfache Weise sichergestellt werden, dass keine unerwünschte Kontaktierung der Stanzgitter untereinan¬ der stattfindet. Zudem lässt sich so besonders günstig ein wohl defi¬ nierter Abstand zwischen den Stanzgittern einstellen.In a preferred embodiment, at least one insulating element, in particular a spacer, is arranged between the first and third stamped grid and / or between the second and third stamped grid. As a result, it can be ensured in a simple manner that no undesired contacting of the stamped grids takes place underneath. In addition, a well-defined distance between the punched grids can be adjusted in a particularly favorable manner.
Vorteilhaft ist es auch, wenn zwischen erstem und zweitem Stanzgit- ter ein drittes Stanzgitter angeordnet ist, welches eine Ausnehmung mit mindestens einer Kontaktzone aufweist, in der die Kontaktzunge angeordnet ist und mindestens an der Kontaktzone anliegt. So lässt sich einfach und günstig eine Kontaktierung aller Stanzgitter unter¬ einander realisieren.It is also advantageous if a third stamped grid is arranged between the first and second stamped grid, which has a recess with at least one contact zone in which the contact tongue is arranged and bears against at least the contact zone. This makes it easy and inexpensive to realize a contacting of all stamped grid unter¬ each other.

Beschreibung der AusführungsbeispieleDescription of the embodiments
Figur 1 zeigt einen Ausschnitt eines zweiten Stanzgitters 12 mit einer Ausnehmung 14. Im Inneren der Ausnehmung 14 ist eine Kontaktzo¬ ne 16 ausgebildet, die drei Kontaktnasen 18 aufweist. Die Kontakt¬ nasen 18 sind teilelastisch. Zudem sei darauf hingewiesen, dass die Ausnehmung 14 - in Abhängigkeit von der zu lösenden technischen Situation - beliebige Formen aufweisen kann, sofern die beschriebe- ne elektrische Kontaktierung sichergestellt wird.FIG. 1 shows a detail of a second stamped grid 12 with a recess 14. A contact zone 16, which has three contact tabs 18, is formed in the interior of the recess 14. The Kontakt¬ noses 18 are partially elastic. In addition, it should be pointed out that the recess 14-depending on the technical situation to be solved-can have any desired shapes, provided the described electrical contacting is ensured.
Eine weitere Ausführungsform zeigt die Figur 2, bei der der elektri¬ sche Kontakt mittels zweier Kontaktnasen 18 hergestellt wird. Die Ausführungen zur Figur 1 sind hier entsprechend anzuwenden. Na- türlich sind auch andere Formen geeignet.A further embodiment is shown in FIG. 2, in which the electrical contact is produced by means of two contact lugs 18. The comments on Figure 1 are here to apply accordingly. Of course, other shapes are also suitable.
Das Verfahren zum elektrischen Kontaktieren von zwei leitenden Stanzgittern 10,12, sowie eine Anordnung 20 von zwei elektrisch lei¬ tenden Stanzgittern 10,12 zeigt die Figur 3. Dabei wird dieselbe An- Ordnung 20 einmal in der Seitenansicht und einmal in der Draufsicht gezeigt. In der Seitenansicht ist ein erstes Stanzgitter 10 zu sehen, welches parallel zum zweiten Stanzgitter 12 angeordnet ist. Mittels der gestrichelten Linien ist die Ausrichtung einer Kontaktzunge 22 angedeutet, wie sie sich unmittelbar nach dem Stanzen des ersten Stanzgitters 10 darstellt. Im vorderen Bereich der Kontaktzunge 22 ist in Form einer Materialverjüngung eine Einführhilfe 24 ausgebildet. Nachdem die beiden Stanzgitter 10,12 ausgestanzt sind, wird die Kontaktzunge 22 in eine zum ersten Stanzgitter 10 rechtwinklige Po- sition gebogen. In einem weiteren Schritt werden die Stanzgitter 10,12 zueinander parallel ausgerichtet, wobei die Kontaktzunge 22 mit der Einführhilfe 24 so positioniert wird, dass sie der Ausnehmung 14 zugeordnet ist. Die beiden Stanzgitter 10,12 werden dann aufein¬ ander zu bewegt, wobei die Kontaktzunge 22 in die Ausnehmung 14 eintritt und dabei die Kontaktnasen 18 verbiegt. Die Kontaktnasen 18 drücken dabei gegen die Kontaktzunge 22, sodass ein sicherer elekt¬ rischer Kontakt gewährleistet ist. In der Seitenansicht ist auch deut¬ lich zu erkennen, dass die Kontaktzunge 22 auch wieder aus der Ausnehmung 14 herausgezogen werden kann, um erstes und zwei- tes Stanzgitter 10,12 wieder voneinander zu trennen.The method for electrically contacting two conductive stamped gratings 10, 12, as well as an arrangement 20 of two electrically conductive punched gratings 10, 12 is shown in FIG. 3. The same arrangement 20 is shown once in the side view and once in plan view. In the side view, a first punched grid 10 can be seen, which is arranged parallel to the second punched grid 12. By means of the dashed lines, the orientation of a contact tongue 22 is indicated, as they are immediately after the punching of the first Punching grid 10 represents. In the front region of the contact tongue 22, an insertion aid 24 is formed in the form of a material taper. After the two stamped gratings 10, 12 are punched out, the contact tongue 22 is bent in a position perpendicular to the first stamped grid 10. In a further step, the lead frames 10, 12 are aligned parallel to one another, the contact tongue 22 being positioned with the insertion aid 24 in such a way that it is assigned to the recess 14. The two punched grids 10, 12 are then moved toward one another, wherein the contact tongue 22 enters the recess 14 and thereby bends the contact tabs 18. The contact tabs 18 press against the contact tongue 22, so that a secure elekt¬ rischer contact is ensured. It can also be clearly seen in the side view that the contact tongue 22 can also be pulled out of the recess 14 again in order to separate first and second punched grid 10, 12 from one another.
In der Figur 4 ist eine Anordnung gezeigt - wiederum als Seitenan¬ sicht und als Draufsicht -, bei der zwischen dem ersten und zweiten Stanzgitter 10,12 ein drittes Stanzgitter 26 angeordnet ist. Dabei soll hier ein elektrischer Kontakt zwischen erstem und drittem Stanzgitter 10,26 hergestellt werden und kein Kontakt zum zweiten Stanzgitter 12 bestehen. Dafür weist das dritte Stanzgitter die bereits bekannte Ausnehmung 14 auf, während das zweite Stanzgitter 12 eine Aus¬ sparung 28 aufweist, die so groß ist, dass die Kontaktzunge 22 kei- nen Kontakt zum zweiten Stanzgitter 12 herstellt. Im dargestellten Fall ist die Aussparung 28 zudem so groß, dass auch die gebogenen Kontaktnasen 18 keinen elektrischen Kontakt zum zweiten Stanzgit¬ ter 12 herstellen können.FIG. 4 shows an arrangement - again as a side view and as a plan view - in which a third punched grid 26 is arranged between the first and second stamped grid 10, 12. Here is an electrical contact between the first and third punched grid 10,26 are made and no contact with the second lead frame 12 exist. For this purpose, the third stamped grid has the already known recess 14, while the second stamped grid 12 has a recess 28 which is so large that the contact tongue 22 does not make contact with the second stamped grid 12. In the case shown, the recess 28 is also so large that even the bent contact tabs 18 can not make electrical contact with the second stamped grid 12.
Figur 5 zeigt eine ähnliche Situation, jedoch soll hier ein elektrischer Kontakt zwischen erstem und zweitem Stanzgitter 10,12 hergestellt werden, während das dritte Stanzgitter 26 nicht kontaktiert wird. In diesem Fall ist die Ausnehmung 14 am zweiten Stanzgitter 12 ange¬ ordnet, während die Aussparung 28 am dritten Stanzgitter 26 ange- ordnet ist. Zudem ist zwischen dem ersten und dem dritten Stanzgit¬ ter 10,26 ein isolierendes Element 30 angeordnet, welches gleichzei¬ tig die Funktion eines Abstandhalters 32 erfüllt. Mittels dieses Ele¬ mentes 30 kann insbesondere sichergestellt werden, dass auch bei einem später auftretenden Druck auf das erste Stanzgitter 10, dieses nicht mit dem dritten Stanzgitter 26 in elektrischen Kontakt tritt.Figure 5 shows a similar situation, but here an electrical contact between the first and second punched grid 10,12 are made while the third punched grid 26 is not contacted. In this case, the recess 14 is arranged on the second stamped grid 12, while the cutout 28 is attached to the third stamped grid 26. is orders. In addition, an insulating element 30 is arranged between the first and the third stamped grid 10, 26, which at the same time fulfills the function of a spacer 32. By means of this element 30, it can be ensured, in particular, that even with a later occurring pressure on the first stamped grid 10, this does not come into electrical contact with the third stamped grid 26.
In der Figur 6 wird gezeigt, wie eine Verbindung von einem ersten, einem zweiten und einem dritten Stanzgitter 10,12,26 realisiert wer- den kann. Dafür sind sowohl auf dem zweiten Stanzgitter 12 als auch auf dem dritten Stanzgitter 26 Ausnehmungen 14 angeordnet, die von der Kontaktzunge 22 durchdrungen werden. Es sei dabei darauf hingewiesen, dass die Kontaktnasen 18 des dritten Stanzgitters 26 auf dem zweiten Stanzgitter 12 aufliegen. Neben einer Verbesserung des elektrischen Kontaktes wird auch die mechanische Stabilität die¬ ser Anordnung erhöht, insbesondere da die gebogenen Kontaktna¬ sen 14 des dritten Stanzgitters 26 auch einen Abstand zwischen zweitem und drittem Stanzgitter 12,26 definieren.FIG. 6 shows how a connection of a first, a second and a third stamped grid 10, 12, 26 can be realized. For this purpose, recesses 14 are arranged both on the second stamped grid 12 and on the third stamped grid 26, which are penetrated by the contact tongue 22. It should be noted that the contact lugs 18 of the third punched grid 26 rest on the second punched grid 12. In addition to an improvement in the electrical contact, the mechanical stability of this arrangement is also increased, in particular because the bent contact bases 14 of the third stamped grid 26 also define a spacing between the second and third stamped grid 12, 26.
Mittels der Erfindung lässt sich die Oberfläche eines jeden Stanzgit¬ ters effizient nutzen, da nun das Planen und Anlegen der Verbin¬ dungsbahnen erleichtert ist. Zudem handelt es sich hier um eine sehr zuverlässige Verbindung, die im Herstellungsverfahren standardisier¬ ten Qualitätskontrollen unterzogen werden kann. Anordnungen, die erfindungsgemäß gefertigt werden, bieten eine sichere elektrische Verbindung bei hoher mechanischer Stabilität wobei sich zudem die Möglichkeit einer Demontage von miteinander verbundenen Stanzgit¬ tern ergibt. By means of the invention, the surface of each stamped grid can be used efficiently, since the planning and application of the connecting paths is now facilitated. Moreover, this is a very reliable compound which can be subjected to standardized quality controls in the production process. Arrangements which are manufactured according to the invention provide a secure electrical connection with high mechanical stability, with the possibility of dismantling interconnected stamped bars.
