Abstract

To avoid abrasion during insertion of plug-in pins or printed circuit boards in contact springs which are arranged in sets, said springs are shaped so that they are bent in their upper part by the pin or board which is introduced and brought into contact with them only towards the end of the plugging-in process.

Description

Kontaktfeder zur Verwendung in Gehäusen mit im wesentlichen U-förmigem QuerschnittContact spring for use in housings with a substantially U-shaped cross section
Beschreibungdescription
Gegenstand der Erfindung ist eine Kontaktfeder zur Verwendung in Gehäusen mit im wesentlichen U-förmigem Querschnitten dem eine Mehrzahl von Kontaktfedern in einer Reihe oder paarweise einander gegenüberliegend als Gegenfedern in zwei Reihen angeordnet sind.The invention relates to a contact spring for use in housings with a substantially U-shaped cross-section, in which a plurality of contact springs are arranged in a row or in pairs opposite one another as counter springs in two rows.
Derartige Kontaktfedern werden gewöhnlich zur Kontaktierung von auf Karten gedruckten Schaltungen benutzt. Während im gewöhnlichen Spiel von Stecker und Buchse die beim Steckvorgang auftretende Reibung als Reinigung der kontaktgebenden Oberflächen er¬ wünscht ist, sind die zum Kontaktieren von Karten auf diesen befindlichen leitenden Flächen sehr dünn, so daß ein Abrieb beim Steckvorgang möglichst vermieden werden soll. Dies ist jedoch mit herkömmlichen Kontakt¬ federn schwierig, weil diese praktisch über den ganzen Steckvorgang auf der leitenden Fläche aufliegen und reiben. Vergleichbares gilt für empfindliche Stecker¬ stifte.Such contact springs are usually used for contacting circuits printed on cards. While in the usual game of plug and socket the friction occurring during the plug-in process is desired as cleaning of the contacting surfaces, the conductive surfaces located on these for contacting cards are very thin so that abrasion during the plug-in process should be avoided as far as possible. However, this is difficult with conventional contact springs because they rest and rub on the conductive surface practically throughout the entire plug-in process. The same applies to sensitive plug pins.
Der Erfindung liegt die Aufgabe zugrunde, eine Kontakt¬ feder anzugeben, mit der beim Steckvorgang die leiten¬ den Flächen auf der Karte oder dem Stift weitgehend geschont werden. Der Lösung liegt die Überlegung zugrunde, den Steckvor¬ gang und die Kontaktierung nicht wie bei den üblichen Ausführungsformen gleichzeitig vorzunehmen, sondern in zwei zeitlich aufeinander folgende Vorgänge zu trennen. Demgemäß besteht die erfindungsgemäße Lösung der Auf¬ gabe darin, daß die Kontaktfeder derart profiliert ist, daß sie in ungestecktem Zustand an der Öffnung des Gehäuses nach innen auslenkbar ist und gegen die ihr gegenüberliegende Innenwand des Gehäuses oder ihre Gegenfeder einen solchen Abstand aufweist, daß eine Karte mit einer gedruckten Schaltung oder Steckerstifte mindestens annähernd reibungslos eingeführt werden können, daß sie am Boden des Gehäuses gegen die Ge¬ häusewand auslenkbar ist und gegen die ihr gegenüber¬ liegende Gehäusewand oder ihre Gegenfeder einen solchen Abstand aufweist, daß eine Karte mit einer gedruckten Schaltung oder ein Steckerstift gegen Ende des Ein¬ führungsvorganges eine Auslenkung dieses Teiles der Kontaktfeder gegen die Gehäusewand bewirkt und daß sie gegen Ende des Einführungsvorganges mit ihren gegen die Karte oder den Steckerstift gerichteten Flächen um einen etwa auf der Hälfte der Länge dieser Flächen befindlichen Punkt derart geschwenkt wird, daß sie im Bereich der Öffnung des Gehäuses mit hinreichen¬ dem Kontaktdruck an der Karte oder am Steckerstift anliegt.The invention is based on the object of specifying a contact spring with which the conductive surfaces on the card or the pin are largely protected during the plugging process. The solution is based on the consideration not to carry out the plug-in operation and the contacting simultaneously as in the conventional embodiments, but to separate them in two successive operations. Accordingly, the solution of the task according to the invention is that the contact spring is profiled in such a way that it can be deflected inwards in the unplugged state at the opening of the housing and is at a distance from the inner wall of the housing opposite it or its counter spring such that a A card with a printed circuit or plug pins can be inserted at least approximately smoothly, that it can be deflected at the bottom of the housing against the housing wall and against the housing wall or its counterspring opposite it at such a distance that a card with a printed circuit or a plug pin towards the end of the insertion process causes a deflection of this part of the contact spring against the housing wall and that it faces the end of the insertion process with its surfaces directed against the card or the plug pin by approximately half the length of these surfaces The point is pivoted in such a way that it lies in the area of the opening of the housing with sufficient contact pressure on the card or on the plug pin.
Der besondere Vorteil der erfindungsgemäßen Form der Kontaktfeder ist darin zu sehen, daß zum Beispiel der Rand der eingeführten Karte erst gegen Ende des Steck¬ vorganges auf die Kontaktfeder drückt und dadurch das Anlegen ihres der Gehäuseöffnung nahen Teiles an die leitende Fläche der Karte bewirkt. Die leitende Fläche braucht sich also nicht bis an den Kartenrand zu er¬ strecken, so daß sie keinerlei Reibungsbeanspruchung durch den Steckvorgang ausgesetzt ist. Auch unter¬ bleiben Deformationen der leitenden Fläche, die bei herkömmlichen Ausführungsformen leicht zu Kurzschlüssen führten. In einer erfindungsgemäßen Ausführungsform tritt die Kontaktfeder etwa auf der halben Länge der Tiefe des Gehäuses durch dessen Wand nach innen ein, verläuft in einem Abstand von der Wand gegen den Gehäuseboden, istThe particular advantage of the shape of the contact spring according to the invention can be seen in the fact that, for example, the edge of the inserted card only presses on the contact spring towards the end of the plug-in process and thereby causes its part close to the housing opening to be placed on the conductive surface of the card. The conductive surface therefore does not have to extend to the edge of the card, so that it is not exposed to any frictional stress due to the insertion process. Deformations of the conductive surface also remain, which in conventional embodiments easily led to short circuits. In one embodiment according to the invention, the contact spring enters approximately half the length of the depth of the housing through the wall thereof, runs at a distance from the wall against the housing base
«• dort gegen die Mitte des Gehäuses gekröpft und ver¬ läuft dann in ungestrecktem Zustand mit einem gegenüberCranked there against the middle of the housing and then runs in the undrawn state with one opposite
^ der Kröpfung vergrößerten Abstand gegen die Gehäuse¬ mitte, etwa parallel zur Gehäusewand bis nahe an die Öffnung des Gehäuses.^ The offset increased distance from the housing center, approximately parallel to the housing wall up to close to the opening of the housing.
Ein Ausführungsbeispiel der im vorstehenden Absatz be¬ schriebene Ausführungsform der erfindungsgemäßen Kontaktfeder ist in zum Teil schematischer Darstellung in den Figuren 1 bis 4 wiedergegeben.An exemplary embodiment of the embodiment of the contact spring according to the invention described in the preceding paragraph is shown in a partially schematic illustration in FIGS. 1 to 4.
In Figur 1 ist mit 1 das Gehäuse bezeichnet, dessen Ausnehmung 2 zwei Reihen von paarweise einander gegen¬ überliegenden Kontaktfedern 3 aufnimmt. Die Kontakt¬ federn 3 treten bei 4 etwa auf der halben Länge der Tiefe der Ausnehmung 2 des Gehäuses 1 durch dessen Wand nach innen ein. Sie verlaufen bei 5 in einem Ab¬ stand von der Wand gegen den Gehäuseboden. Dort sind sie bei 6 gegen die Mitte des Gehäuses gekröpft und verlaufen sodann mit einem gegenüber der Kröpfung ver¬ größertem Abstand gegen die Gehäusemitte etwa parallel, zur Gehäusewand bis nahe an die Öffnung 7 des Gehäuses.In FIG. 1, 1 denotes the housing, the recess 2 of which accommodates two rows of contact springs 3 lying opposite one another in pairs. The contact springs 3 enter at 4 about half the length of the depth of the recess 2 of the housing 1 through its wall inwards. They run at 5 at a distance from the wall against the housing base. There they are cranked at 6 against the center of the housing and then run approximately parallel to the housing wall at a greater distance than the crank from the cranking, up to the opening 7 of the housing.
Figur 2 zeigt die Funktion einer erfindungsgemäßen Kontaktfeder, wobei die rechte Feder 8 in ungestrecktem Zustand und die linke Feder 9 in gestrecktem Zustand dargestellt ist. In ungestrecktem Zustand sind die Federn 8 und 9 soweit voneinander entfernt, daß zum Beispiel eine Karte 10 mit einer gedruckten Schaltung mindestens annähernd reibungslos durch die Öffnung in die Ausnehmung des Gehäuses eingeführt werden kann. Erst wenn der untere Rand der Karte 10 die Kröpfungen 11 und 12 erreicht, werden diese gegen die Gehäusewandung gedrückt. Die zur Kontaktgabe bestimmten Teile- der Kontaktfedern 8 und 9 gelangen zunächst mit ihren Rückseiten zur Anlage 13 und 14, die durch Materialverdichtung be¬ sonders elastisch ausgebildet sind. Im Zuge der weiteren Auslenkung gelangt dann der in der Nähe der Öffnung des Gehäuses befindliche, zur Kontaktgabe bestimmte Teil der Kontaktfedern 8 und 9 zur Anlage an die Karte 10.FIG. 2 shows the function of a contact spring according to the invention, the right spring 8 being shown in the unstretched state and the left spring 9 being shown in the stretched state. In the unstretched state, the springs 8 and 9 are so far apart that, for example, a card 10 with a printed circuit can be inserted at least approximately smoothly through the opening into the recess in the housing. Only when the lower edge of the card 10 reaches the cranks 11 and 12 are they pressed against the housing wall. The parts of the contact springs 8 and 9 intended for contacting initially come with their rear sides to the system 13 and 14, which are particularly elastic due to material compression. In the course of the further deflection, the part of the contact springs 8 and 9 located near the opening of the housing and intended to make contact then comes into contact with the card 10.
Figur 3 zeigt die gestreckte Karte, wobei zu erkennen ist, daß der untere Rand 15 der Karte von den leitenden Flächen 16 freigehalten werden kann.Figure 3 shows the stretched card, it can be seen that the lower edge 15 of the card can be kept free from the conductive surfaces 16.
In einer weiteren erfindungsgemäßen Ausführungsform tritt die Kontaktfeder in der Nähe des Bodens der Aus¬ nehmung in diese ein. Sie wird sodann entlang der Innen¬ wand des Gehäuses gegen die Öffnung des Gehäuses ge¬ führt, dort um 180 nach unten umgelenkt und mit ihrem freien Ende gegen die Mitte der Ausnehmung abgebogen und einer ihrer parallel zur Gehäusewand verlaufenden, Teile weist etwa auf halber Höhe vom Boden des Gehäuses gegenüber dem anderen Teil einen Nocken auf.In a further embodiment according to the invention, the contact spring enters the recess near the bottom thereof. It is then guided along the inner wall of the housing against the opening of the housing, deflected there by 180 and bent with its free end towards the center of the recess and one of its parts running parallel to the housing wall has approximately half the height a cam from the bottom of the housing opposite the other part.
In Figur 4 ist in zum Teil schematischer Darstellung ein Ausführungsbeispiel der im vorstehenden Absatz be¬ schriebenen Ausführungsform wiedergegeben.An exemplary embodiment of the embodiment described in the preceding paragraph is shown in FIG. 4 in a partially schematic representation.
Die Kontaktfedern 17 und 18 treten bei dieser Ausfüh¬ rungsform in der Nähe des Bodens der Ausnehmung 19 des Gehäuses 20 ein. Sie sind sodann entlang der Innenwand des Gehäuses 20 gegen dessen Öffnung 21 geführt. Dort sind sie bei 22 und 23 um 180 nach unten ungelenkt und mit ihren freien Enden 24 und 25 gegen die Mitte der Ausnehmung 19 abgebogen. Einer ihrer parallel zur Gehäusewand verlaufenden Teile weist etwa auf halber Höhe vom Boden des Gehäuses 20 gegen den anderen Teil Nocken 28 und 29 auf. Um die Wirkung der Vielzahl der Kontaktfedern zu vergleichmäßigen ist es von Vorteil, wenn in Weiter¬ bildung der Erfindung einander benachbarte Kontakt¬ federn an ihren dem Gehäuseboden zunächst gelegenen Teilen durch einesenkrecht zu ihnen verlaufende Kunst¬ stoffleiste kraftschlüssig miteinander verbunden sind. Solche Kunststoffleisten sind in Figur 4 mit 30 und 31 bezeichnet.The contact springs 17 and 18 occur in this embodiment in the vicinity of the bottom of the recess 19 of the housing 20. They are then guided along the inner wall of the housing 20 against the opening 21 thereof. There they are unguided at 22 and 23 by 180 and bent with their free ends 24 and 25 towards the center of the recess 19. One of its parts running parallel to the housing wall has cams 28 and 29 at about half the height from the bottom of the housing 20 against the other part. In order to even out the effect of the large number of contact springs, it is advantageous if, in a further development of the invention, adjacent contact springs are non-positively connected to one another on their parts initially located on the housing base by a plastic strip running perpendicular to them. Such plastic strips are designated in Figure 4 with 30 and 31.
Weiterhin ist es von Vorteil, die Kontaktfedern im Verlauf ihrer Länge mit unterschiedlicher Stärke aus¬ zubilden. Sie können so besser an die Beanspruchung der betreffenden Teillänge angepaßt werden.Furthermore, it is advantageous to design the contact springs with different thicknesses over the course of their length. They can thus be better adapted to the stress of the partial length concerned.
Zur Erleichterung der Montage dient es, wenn die Gehäuse in der Höhe der Eintrittsöffnungen der Kontaktfedern in zwei Teile unterteilt sind, wie dies in Figur 4 bei 26 und 27 angedeutet ist. To facilitate assembly, it is used if the housings are divided into two parts at the height of the inlet openings of the contact springs, as is indicated in FIG. 4 at 26 and 27.
