Abstract
Description
Die Erfindung betrifft eine Befestigung für ein zumindest zwei Kontaktfahnen aufweisendes Kontaktteil auf einer Platine, in welcher den Kontaktfahnen entsprechende Aus nehmungen eingearbeitet sind und welche Leiterbahnen hat, die mit den Kontaktfahnen verlötet sind.The invention relates to a fastening for at least one two contact tabs on one Circuit board in which the contact lugs correspond acceptances are incorporated and which conductor tracks have which are soldered to the contact flags.
Solche Befestigungen werden in der Elektrotechnik viel fach eingesetzt und sind damit bekannt. Das Kontaktteil dient häufig dazu, die Platine mit elektrischen Leitungen oder einer weiteren Platine zu verbinden. Auch große und schwere auf der Platine zu befestigende Bauteile wie bei spielsweise ein Transformator haben häufig Kontaktteile mit mehreren Kontaktfahnen, welche jeweils in eine eigene Ausnehmung der Platine eingesetzt werden. Die Platine hat dann im Bereich zumindest einer der Ausnehmungen eine Leiterbahn, die mit der entsprechenden Kontaktfahne ver lötet wird. Such fastenings are much in electrical engineering used and are known. The contact part often serves the board with electrical wires or to connect another board. Large and too heavy components to be attached to the board as with for example a transformer often have contact parts with several contact flags, each in its own Recess of the board can be used. The board has then one in the area of at least one of the recesses Conductor that ver with the corresponding contact flag is soldered.
Nachteilig bei einer solchen Befestigung ist, daß auf die Befestigung wirkende Montagekräfte oder Erschütterungen des Kontaktteils auf die Lötstelle übertragen werden. Dies führt innerhalb der Lötstelle häufig zu Rekristalli sationsvorgängen, die zu einem Ausfall ihrer elektrischen Leitfähigkeit führen.A disadvantage of such an attachment is that on the Fastening installation forces or vibrations of the contact part are transferred to the solder joint. This often leads to recrystallization within the solder joint operations that lead to a failure of their electrical Conductivity.
Der Erfindung liegt das Problem zugrunde, eine Befesti gung der eingangs genannten Art so zu gestalten, daß die Gefahr eines Ausfalls der elektrischen Leitfähigkeit deutlich vermindert wird.The invention is based on the problem of a fastening tion of the type mentioned so that the Risk of loss of electrical conductivity is significantly reduced.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß eine erste Kontaktfahne kleinere Abmessungen hat als die entsprechende Ausnehmung in der Platine und daß alle üb rigen Kontaktfahnen als Verankerungsglieder in die Pla tine eingepreßt sind.This problem is solved according to the invention in that a first contact lug has smaller dimensions than that corresponding recess in the board and that all over contact flags as anchoring elements in the pla tine are pressed.
Durch diese Gestaltung der Befestigung werden die auf das Kontaktteil wirkenden Kräfte von den eingepreßten Kon taktfahnen aufgenommen. Durch die Aufteilung der an die Kontaktfahnen gestellten Anforderungen auf mechanische Stabilität und elektrische Leitfähigkeit kommt es selbst bei hohen mechanischen Belastungen nicht mehr zu Rekri stallisationsvorgängen und damit zu einem Ausfall der elektrischen Leitfähigkeit der Befestigung. Dank der Er findung können beliebig viele Kontaktfahnen in der Pla tine eingepreßt sein. Wenn die Richtungen der auf das Kontaktteil wirkenden mechanischen Belastungen bekannt ist, genügt es, das Kontaktteil mit insgesamt zwei Kon taktfahnen auszubilden, von denen eine in die Platine eingepreßt ist. Weiterhin ist das Kontaktteil im Bereich der Lötstellen beim Lötvorgang spannungsfrei gehalten, so daß die Gefahr sogenannter kalter und damit elektrisch nichtleitender Lötstellen deutlich verringert ist. By this design of the attachment to the Contact part forces from the pressed-in Kon clock flags added. By dividing the to the Contact flags made demands on mechanical Stability and electrical conductivity come about themselves at high mechanical loads no longer a problem installation processes and thus a failure of the electrical conductivity of the attachment. Thanks to the Er Any number of contact flags can be found in the pla be pressed in. If the directions of the on that Contact part acting mechanical loads known is, it is sufficient to the contact part with a total of two cones train clock flags, one of which is in the circuit board is pressed. Furthermore, the contact part is in the area the soldering points are kept stress-free during the soldering process, see above that the danger of so-called cold and therefore electrical non-conductive solder joints is significantly reduced.
Heutige Leiterbahnen sind häufig auf beiden Seiten mit Leiterbahnen bedruckt. Die Leiterbahnen müssen dann mit den entsprechenden Kontaktfahnen auch auf beiden Seiten verlötet werden. Die erfindungsgemäße Befestigung eignet sich besonders gut für eine solche beidseitig bedruckte Platine und hat gleichzeitig eine hohe Stabilität, wenn die Ausnehmung der ersten Kontaktfahne eine Löthülse hat und ein zwischen der Löthülse und der ersten Kontaktfahne vorhandener Spalt mit Lot ausgefüllt ist. Da hierbei der vom Lot ausgefüllte Spalt von mechanischen Belastungen nicht beansprucht wird, kann der Spalt der ersten Kon taktfahne in der Löthülse auf einen gewünschten Lötspalt angepaßt werden.Today's conductor tracks are often on both sides Printed conductor tracks. The conductor tracks must then go with the corresponding contact flags on both sides to be soldered. The attachment according to the invention is suitable printed particularly well for such a double-sided Circuit board and at the same time has high stability when the recess of the first contact tab has a solder sleeve and one between the solder sleeve and the first contact tab existing gap is filled with solder. Because here the gap filled with solder from mechanical loads is not claimed, the gap of the first con tact flag in the solder sleeve to a desired solder gap be adjusted.
Das Kontaktteil läßt sich gemäß einer anderen vorteilhaf ten Weiterbildung der Erfindung einfach montieren, wenn zumindest eine der in der Platine eingepreßten Kontakt fahnen eine an die Platine an liegende radiale Erweiterung hat. Zur Montage wird das Kontaktteil einfach bis an die einen Anschlag bildende radiale Erweiterung in die Aus nehmung der Platine geführt und ist gleichzeitig in der vorgesehenen Position gehalten. Weiterhin ist es durch diese Gestaltung nicht mehr notwendig, beispielsweise mehrere für eine Steckverbindung notwendige Kontaktteile zuerst in einem ein Steckerteil bildendes Kunststoffge häuse anzuordnen und anschließend das Steckerteil auf der Platine zu befestigen.The contact part can be advantageous according to another easy further development of the invention, if at least one of the contacts pressed into the circuit board flag a radial extension lying on the board Has. For assembly, the contact part is simply up to the radial extension into the stop forming a stop takes the board and is at the same time in the intended position held. Furthermore, it is through this design is no longer necessary, for example several contact parts necessary for a plug connection first in a plastic part forming a plug part Arrange the housing and then the plug part on the Fasten the circuit board.
Die radiale Erweiterung führt nicht zu einer Erhöhung des konstruktiven Aufwandes des Kontaktteils, wenn sie gemäß einer anderen vorteilhaften Weiterbildung der Erfindung von einem die Kontaktfahnen untereinander verbindenden Quersteg gebildet ist.The radial expansion does not lead to an increase in the constructive effort of the contact part, if according to another advantageous development of the invention from one that connects the contact flags to each other Cross bar is formed.
Das Kontaktteil wird gemäß einer vorteilhaften Weiterbil dung der Erfindung formschlüssig in der Platine gehalten, wenn die in der Platine eingepreßten Kontaktfahnen die Platine durchdringen und an ihrer der radialen Erweite rung gegenüberliegenden Seite eine die Platine hinter greifende Lötstelle haben.The contact part is according to an advantageous further development tion of the invention held positively in the board, when the contact lugs pressed into the circuit board Penetrate the board and its radial extent opposite side of the board behind have tangible solder joint.
