- the proposed semiconductor circuit arrangement is characterized by a particularly reliable, störunan réelleen and long-lasting electrical contact between the connection element and the connecting device.
- the inventively proposed electrical contact has a high current carrying capacity and can be produced easily and inexpensively. In particular, it is not necessary to produce a relatively expensive soldering, welding or sintering connection between the connection element and the connection device.
- connection device is understood in particular to mean a film composite in which one or more conductor tracks are applied to a flexible insulating plastic layer or film.
- the plastic layer may also be provided on its top and bottom with conductor tracks.
- the composite film may also be formed of a plurality of plastic layers with interposed conductor tracks. The respective layers can have a layer thickness between 10 ⁇ m and 500 ⁇ m.

- At least one of the contact surfaces is wave-shaped or has a wave-shaped profile. For example, can be ensured by pinching a contact portion with a substantially flat contact surface between an abutment and an abutment with mutually correspondingly shaped wavy contact surfaces safely and reliably a full-surface contact between the contact portions.

Description
Die Erfindung betrifft eine Halbleiterschaltungsanordnung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a semiconductor circuit arrangement according to the preamble of patent claim 1.
Eine solche Halbleiterschaltungsanordnung ist z. B. aus der
Zur Herstellung eines elektrischen Kontakts mit dem Anschlusselement ist ein endständig vorgesehener erster Kontaktabschnitt der Verbindungseinrichtung auf einem im Bereich einer Wand eines Gehäuses vorgesehenen Widerlager abgestützt. Ein in einer Gehäuseausnehmung aufgenommenes gebogenes Federelement zwingt einen zweiten Kontaktabschnitt des Anschlusselements gegen den ersten Kontaktabschnitt.In order to produce an electrical contact with the connection element, a terminal contact section of the connection device provided on the end is supported on an abutment provided in the region of a wall of a housing. A bent spring element accommodated in a housing recess forces a second contact section of the connection element against the first contact section.
Bei der bekannten elektrischen Kontaktierung zwischen dem ersten und dem zweiten Kontaktabschnitt ist konstruktionsbedingt nicht immer ein vollflächiger Kontakt zwischen den Kontaktabschnitten gewährleistet. Das kann insbesondere bei der Übertragung großer Ströme zu einer unerwünschten Erwärmung und dadurch bedingt zu einer Störung des elektrischen Kontakts kommen. Im Falle eines Bruchs des Federelements kann es außerdem nachteiligerweise dazu kommen, dass der elektrische Kontakt zumindest zeitweise vollständig unterbrochen wird.In the known electrical contact between the first and the second contact portion is not always guaranteed a full-surface contact between the contact sections by design. This can lead to unwanted heating and thus to a disruption of the electrical contact, in particular in the transmission of large currents. In case of breakage of the spring element may Moreover, disadvantageously, the electrical contact is at least temporarily interrupted completely.
Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es soll insbesondere eine Halbleiterschaltungsanordnung angegeben werden, welche sich durch einen besonders zuverlässigen Kontakt zwischen dem Anschlusselement und einer Verbindungseinrichtung zur Verbindung mit einer Schaltung auszeichnet.The object of the invention is to eliminate the disadvantages of the prior art. In particular, a semiconductor circuit arrangement is to be specified, which is characterized by a particularly reliable contact between the connection element and a connection device for connection to a circuit.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 2 bis 10.This object is solved by the features of claim 1. Advantageous embodiments of the invention will become apparent from the features of
Nach Maßgabe der Erfindung ist vorgesehen, dass der erste Kontaktabschnitt und/oder der zweite Kontaktabschnitt und/oder das Widerlager eine voneinander verschiedene Kontaktfläche aufweisen, so dass bei Ausübung der Klemmkraft zumindest einer der beiden übereinander angeordneten Kontaktabschnitte verformt und unter der Ausbildung eines elektrischen Kontakts an die Form des anderen Kontaktabschnitts angepasst wird. Die vorgeschlagene Halbleiterschaltungsanordnung zeichnet sich durch einen besonders zuverlässigen, störunanfälligen und langlebigen elektrischen Kontakt zwischen dem Anschlusselement und der Verbindungseinrichtung aus. Der erfindungsgemäß vorgeschlagene elektrische Kontakt weist eine hohe Stromtragfähigkeit auf und lässt sich einfach und kostengünstig herstellen. Es ist insbesondere nicht erforderlich, eine relativ kostenaufwendige Löt-, Schweiß- oder Sinterverbindung zwischen dem Anschlusselement und der Verbindungseinrichtung herzustellen.According to the invention it is provided that the first contact portion and / or the second contact portion and / or the abutment have a mutually different contact surface, so that upon exercise of the clamping force of at least one of the two superimposed contact portions deformed and under the formation of an electrical contact the shape of the other contact section is adjusted. The proposed semiconductor circuit arrangement is characterized by a particularly reliable, störunanfälligen and long-lasting electrical contact between the connection element and the connecting device. The inventively proposed electrical contact has a high current carrying capacity and can be produced easily and inexpensively. In particular, it is not necessary to produce a relatively expensive soldering, welding or sintering connection between the connection element and the connection device.
Im Sinne der vorliegenden Erfindung wird unter dem Begriff "Verbindungseinrichtung" insbesondere ein Folienverbund verstanden, bei dem auf einer flexiblen isolierenden Kunststoffschicht bzw. -folie eine oder mehrere Leiterbahnen aufgebracht sind. Die Kunststoffschicht kann auch auf ihrer Ober- und Unterseite mit Leiterbahnen versehen sein. Der Folienverbund kann auch aus mehreren Kunststoffschichten mit dazwischen eingeschalteten Leiterbahnen gebildet sein. Die jeweiligen Schichten können eine Schichtdicke zwischen 10 µm und 500 µm aufweisen.For the purposes of the present invention, the term "connection device" is understood in particular to mean a film composite in which one or more conductor tracks are applied to a flexible insulating plastic layer or film. The plastic layer may also be provided on its top and bottom with conductor tracks. The composite film may also be formed of a plurality of plastic layers with interposed conductor tracks. The respective layers can have a layer thickness between 10 μm and 500 μm.
Unter dem Begriff "Kontaktabschnitt" wird ein elektrisch leitender Abschnitt des Anschlusselements und/oder Verbindungseinrichtung verstanden. Im Bereich des Kontaktabschnitts ist zweckmäßigerweise eine vollflächige Metallisierung vorgesehen. Die Kontaktabschnitte sind zweckmäßigerweise zueinander korrespondierend hinsichtlich ihrer Größe und Form ausgebildet.The term "contact section" is understood to mean an electrically conductive section of the connection element and / or connection device. In the region of the contact portion, a full-surface metallization is expediently provided. The contact sections are expediently formed corresponding to each other in terms of their size and shape.
Unter dem Begriff "Kontaktfläche" wird diejenige Oberfläche des Kontaktabschnitts verstanden, welche sich im Kontakt mit einer weiteren Kontaktfläche des Widerlagers und/oder eines anderen Kontaktabschnitts befindet. D. h. jeder der Kontaktabschnitte weist zwei "Kontaktflächen" auf. Die beiden "Kontaktflächen" eines Kontaktabschnitts können identisch oder auch unterschiedlich ausgeführt sein. Das Widerlager und/oder das Gegenlager können ebenfalls eine "Kontaktfläche" aufweisen. - Zumindest eine der übereinanliegenden Kontaktflächen weist eine verschiedene Form bzw. ein verschiedenes Profil auf, so dass es beim Aufeinandertreffen der Kontaktabschnitte gegen das Widerlager zu einer Verformung einer der beiden Kontaktabschnitte kommt, bei der die Kontaktflächen sich formschlüssig aneinanderlegen. Es wird damit ein im Wesentlichen vollflächiger Kontakt zwischen den Kontaktflächen erreicht.The term "contact surface" is understood to mean that surface of the contact section which is in contact with a further contact surface of the abutment and / or of another contact section. Ie. Each of the contact sections has two "contact surfaces". The two "contact surfaces" of a contact portion may be identical or different. The abutment and / or the abutment can also have a "contact surface". - At least one of the overlying contact surfaces has a different shape or a different profile, so that it comes at the meeting of the contact portions against the abutment to a deformation of one of the two contact portions, in which the contact surfaces form-fitting together. It essentially becomes one full contact between the contact surfaces achieved.
Vorteilhafterweise ist das Widerlager an einem unterem Gehäuseabschnitt vorgesehen. Insbesondere kann das Widerlager im Bereich eines Wandabschnitts vorgesehen sein. An einem oberen Gehäuseabschnitt kann ein zum Widerlager korrespondierendes Gegenlager vorgesehen sein. In diesem Fall kann auf besonders einfache Weise bei einer Montage des oberen Gehäuseabschnitts am unteren Gehäuseabschnitt eine Klemmkraft auf dazwischen eingelegte Kontaktabschnitte erzeugt werden. D. h. die Kontaktierung zwischen den Kontaktabschnitten kann bei der vorgeschlagenen Ausgestaltung gleichzeitig mit der Montage der Gehäuseabschnitte erfolgen. Die Klemmkraft wird in diesem Fall vorteilhafterweise durch Einklemmen des ersten und des zweiten Kontaktabschnitts zwischen Wider- und Gegenlager hervorgerufen. In diesem Fall erübrigt sich vorteilhafterweise das Vorsehen einer gesonderten Klemmeinrichtung zur Erzeugung der Klemmkraft.Advantageously, the abutment is provided on a lower housing portion. In particular, the abutment may be provided in the region of a wall section. An abutment corresponding to the abutment can be provided on an upper housing section. In this case, in a particularly simple manner when mounting the upper housing section on the lower housing section, a clamping force can be generated on contact sections inserted therebetween. Ie. the contacting between the contact portions can be carried out in the proposed embodiment simultaneously with the mounting of the housing sections. The clamping force is advantageously caused in this case by pinching the first and the second contact portion between abutment and abutment. In this case, the provision of a separate clamping device for generating the clamping force is advantageously unnecessary.
Es ist auch möglich, dass die Klemmkraft durch ein elastisches Mittel erzeugt wird, welches das Wider- oder das Gegenlager bildet. Beispielsweise kann als elastisches Mittel eine dauerelastische Schicht verwendet werden, welche aus einem elastischen Schaumstoff, einem Gummi oder dgl. hergestellt ist.It is also possible that the clamping force is generated by an elastic means which forms the counter or the abutment. For example, as the elastic means, a permanently elastic layer made of an elastic foam, a rubber or the like can be used.
Nach einer vorteilhaften Ausgestaltung ist zumindest eine der Kontaktflächen gewölbt ausgebildet bzw. weist ein gewölbtes Profil auf. Falls die Kontaktfläche des Widerlagers gewölbt ausgebildet ist, ist zweckmäßigerweise eine weitere Kontaktfläche des Gegenlagers korrespondierend dazu ausgebildet. Durch ein Einklemmen beispielsweise im Wesentlichen eben ausgeführter Kontaktabschnitte zwischen den gewölbten Kontaktflächen des Widerlagers und Gegenlagers wird eine Verformung der Kontaktabschnitte und damit ein vollflächiger Kontakt erreicht. Ein ähnlicher Effekt kann erreicht werden, wenn beispielsweise nur eine der beiden Kontaktabschnitte gewölbte Kontaktflächen aufweist oder wenn eine der Kontaktflächen der Kontaktabschnitte gewölbt und die Kontaktflächen des Widersowie Gegenlagers eben ausgebildet sind.According to an advantageous embodiment, at least one of the contact surfaces is curved or has a curved profile. If the contact surface of the abutment is arched, a further contact surface of the abutment is expediently formed corresponding thereto. By pinching, for example, substantially flat executed Contact sections between the curved contact surfaces of the abutment and the abutment deformation of the contact portions and thus a full-surface contact is achieved. A similar effect can be achieved if, for example, only one of the two contact sections has curved contact surfaces or if one of the contact surfaces of the contact sections is curved and the contact surfaces of the anti-reflection abutment are planar.
Nach einer weiteren vorteilhaften Ausgestaltung ist zumindest eine der Kontaktflächen wellenförmig ausgebildet bzw. weist ein wellenförmiges Profil auf. Beispielsweise kann durch ein Einklemmen eines Kontaktabschnitts mit einer im Wesentlichen eben ausgebildeten Kontaktfläche zwischen ein Widerlager und ein Gegenlager mit zueinander korrespondierend ausgebildeten wellenförmigen Kontaktflächen sicher und zuverlässig ein vollflächiger Kontakt zwischen den Kontaktabschnitten gewährleistet werden.According to a further advantageous embodiment, at least one of the contact surfaces is wave-shaped or has a wave-shaped profile. For example, can be ensured by pinching a contact portion with a substantially flat contact surface between an abutment and an abutment with mutually correspondingly shaped wavy contact surfaces safely and reliably a full-surface contact between the contact portions.
Nach einer weiteren Ausgestaltung weist zumindest eine der Kontaktflächen zumindest einen napfartigen Vorsprung auf. Zweckmäßigerweise sind eine Vielzahl solcher Vorsprünge vorgesehen. Die napfartigen Vorsprünge können halbkugelartig, kegelstumpfartig, pyramidenstumpfartig oder dgl. ausgestaltet sein. Falls derartige napfartige Vorsprünge in korrespondierender Ausgestaltung sowohl an den Kontaktflächen der Kontaktabschnitte als auch an den Kontaktflächen des Wider- und Gegenlagers vorgesehen sind, kann in vorteilhafterweise eine Sicherung der Kontaktabschnitte bezüglich des Wider- und/oder Gegenlagers erreicht werden. D. h. bei dieser Ausgestaltung kann das Anschlusselement im Befestigungszustand nicht mehr ohne Weiteres relativ zum Widerlager bewegt werden.According to a further embodiment, at least one of the contact surfaces has at least one cup-like projection. Appropriately, a plurality of such projections are provided. The cup-like projections may be hemispherical, frusto-conical, truncated pyramidal or the like. If such cup-like projections are provided in a corresponding embodiment both on the contact surfaces of the contact portions and on the contact surfaces of the counter and thrust bearing, advantageously a backup of the contact portions with respect to the counter and / or thrust bearing can be achieved. Ie. In this embodiment, the connection element in the attachment state can not be easily moved relative to the abutment.
Nach einer weiteren Ausgestaltung weist zumindest eine der Kontaktflächen langgestreckte Erhebungen auf. Dabei kann es sich beispielsweise um auf den ersten Kontaktabschnitt vorgesehene Leiterbahnen handeln. D. h. bei dieser Ausgestaltung ist also der erste Kontaktabschnitt bewusst nicht vollflächig metallisiert. Falls die Kontaktfläche des zweiten Kontaktabschnitts eben ausgebildet ist, wird im Falle der Ausübung einer Klemmkraft der zweite Kontaktabschnitt an den ersten Kontaktabschnitt angeformt und damit zumindest im Bereich der Leiterbahnen ein vollflächiger elektrischer Kontakt gewährleistet.According to a further embodiment, at least one of the contact surfaces has elongated elevations. This may be, for example, provided on the first contact portion traces. Ie. in this embodiment, therefore, the first contact portion is deliberately not metallized over the entire surface. If the contact surface of the second contact portion is formed flat, in the case of exerting a clamping force, the second contact portion is formed on the first contact portion and thus ensures a full-surface electrical contact at least in the region of the conductor tracks.
