Lötfreie elektrische VerbindungSolderless electrical connection
Die Neuheit bezieht sich auf eine elektrische Verbindung für gedruckte Schaltungsplatten, vorwiegend für "Multi-Layer" Schaltungsplatten und mehrlagigen Anordnungen von gedruckten Schaltungsplatten. Die Verbindung wird durch geprägte Messer- oder Federkontakte hergestellt. dc»ren anderes Ende so gestaltet ist, daß eine Weiterverdrahtung in "Wire-Wrap", "Tsrmi-Point"-Technik oder anderen Verfahren möglich ist.The novelty relates to an electrical connection for printed circuit boards, primarily for "multi-layer" Circuit boards and multilayer printed circuit board assemblies. The connection is through Embossed knife or spring contacts made. the other The end is designed in such a way that further wiring can be carried out using "Wire-Wrap", "Tsrmi-Point" technology or other methods is possible.
Derartige Kontakte werden häufig dazu verwendet, auf Schaltungsplatten angeordnete gedruckte Schaltungen über Messeroder Federleisten mit anderen gedruckten Schaltungsplatten, die austauschbar, sind, elektrisch zu verbinden.Such contacts are often used on circuit boards Arranged printed circuits via male or female connectors with other printed circuit boards, which are interchangeable, electrically connectable.
Auf der anderen Seite der Schaltungsplatten werden in der Regel die durchragenden Kontakte mit einer variablen, durch Drähte hergestellte Schaltung, verbunden; was mit den bekannten Verfahren "Wire-Wrap", "Termi-Point" usw. geschieht.On the other side of the circuit board, the protruding contacts with a variable, through Wires made circuit, connected; what happens with the well-known "Wire-Wrap", "Termi-Point" and so on.

In fast allen Fällen werden die Kontakte in die ein- oder mehrlagigen*gedruckten Schaltungsplatten eingelötet. Dies geschieht von Hand mit einem Lötkolben, mit Lötringen oder mittels eines Lötschwallbades.In almost all cases the contacts are in the one or multilayer * printed circuit boards soldered in. this done by hand with a soldering iron, with soldering rings or by means of a solder wave bath.
Der Nachteil dieses Verfahrens ist, daß mit hohen Temperaturen gearbeitet werden muß. Das führt zu Spannungen in den Schaltungsplatten. Diese Spannungen bewirken ein Verbiegen der Schaltungsplatten und führen häufig zu Rißbildungen an den dünnen Schaltungsleitungen auf den gedruckten Platten. Diese Risse machen die teuren Schaltungsplatten unbrauchbar.The disadvantage of this process is that it involves high temperatures must be worked. This leads to stress in the circuit boards. These tensions cause bending of the circuit boards and often cracks the thin circuit lines on the printed circuit boards. These cracks make the expensive circuit boards unusable.
Ein weiterer Nachteil beim Löten ist die Verunreinigung der durchragenden Kontakte mit Lötmittelresten, was zu Störungen bei der variablen Verdrahtung führt.Another disadvantage of soldering is the contamination of the protruding contacts with solder residue, which can lead to malfunctions with variable wiring.
Der Neuheit liegt die Aufgabe zugrunde, eine elektrische verbindung bei ein- öder mehrlagigen SchaItungsplatten zu schaffen, bei der die Nachteile der Lötverbindung ausgeschlossen werden.The novelty is based on the task of being an electric connection with single or multi-layer circuit boards create in which the disadvantages of the soldered connection are excluded.
Diese Aufgabe wird gemäß der Neuheit dadurch gelöst, daß die durchkontaktierten Löcher der gedruckten Schaltungsplatten mit einer dicken, weichen, chemischen oder galvanischen Oberfläche versehen werden, in der der Kontakt in seiner besonders geprägten Zone durch Flächen- oder Kantenpressung mit der gedruckten Schaltung Kontakt macht.This object is achieved according to the novelty in that the plated through holes of the printed circuit boards be provided with a thick, soft, chemical or galvanic surface, in which the contact in its special embossed zone makes contact with the printed circuit by surface or edge pressure.
Durch die Prägung an den Kontakten wird eine genaue und glatte Zone geschaffen, die den festen Halt in der gedruckten Schaltungsplatte gewährleistet.The embossing on the contacts makes it accurate and smooth Zone created that ensures the firm hold in the printed circuit board.
Die Kontakte können aus Profildraht hergestellt werden und von Hand oder mit Bestückungsmaschinen in die gedruckte Platte eingedrückt werden. Vorteilhaft ist aber auch, die Kontakte aus eineiB Band zu stanzen und zu prägen und sie am Stanzstreifen, der nach dem Einsetzen abgebrochen wird, zu montieren.The contacts can be made from profile wire and be pressed into the printed board by hand or with a pick and place machine. The contacts are also beneficial punching and embossing from a ribbon and attaching it to the punching strip, which is broken off after insertion.

Um die Kontakte vor Beschädigung zu schützen, kann ein Isolierkörper über die Kontakte gesteckt werden, der durch die Kontakte gehalten oder an der gedruckten Platte befestigt wird. Durch die Ausbildung des Isolierkörpers mit einem Kragen, Steg oder ähnlichem, kann eine Vorführung zum Gegenstecker erreicht werden. To protect the contacts from damage, an insulating body can be slipped over the contacts and held by the contacts or attached to the printed circuit board . By designing the insulating body with a collar, web or the like, a demonstration of the mating connector can be achieved.
Gegenstand der Neuheit ist auch eine Anordnung, in der die Kontakte vorher in einem Isolierkörper montiert sind und zusammen mit dem Isolierkörper in die gedruckte Schaltungsplatte eingedrückt werden. Hierbei ist der Isolierkörper so gestaltet, daß die Halterung der Kontakte im Isolierkörper verhältnismäßig weit entfernt von der Oberkante der gedruckten Platte liegt, so daß sich Toleranzunterschiede zwischen den Löchern in der gedruckten Platte und den Halterungen im Isolierkörper ausgleichen können.The novelty is also an arrangement in which the contacts are previously mounted in an insulating body and together with the insulator pressed into the printed circuit board. The insulating body is designed in such a way that that the holder of the contacts in the insulator is relatively far from the top of the printed Plate is so that there are tolerance differences between the holes in the printed board and the brackets in the insulator can compensate.
Weitere Merkmale und Vorteile der Neuheit ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung. Darin zeigt:Further features and advantages of the novelty emerge from the following description of exemplary embodiments the drawing. It shows:
