FederleisteFemale connector
Die Erfindung betrifft eine Federleiste, insbesondere für die steckbareAufnahme von Leiterplatten od.dgl. mit einem Kontaktfedern aufnehmenden Leistenkörperund an den Enden desselben angeordnete, im wesentlichen u-förmige Stützleisten,die Führungsnuten für die Leiterplatten mit in diesen einragenden Klemmitteln aufweisen.The invention relates to a spring strip, in particular for the plug-inRecording of circuit boards or the like. with a strip body receiving contact springsand at the ends of the same arranged, essentially U-shaped support strips,have the guide grooves for the circuit boards with clamping means protruding into them.
Es ist bekannt, die in den Stützleisten dieser Federleisten eingeschobenenLeiterplatten zur Vermeidung eines Klirreffekts durch an einer Seitenwand jederFührungsnuten eingebogene Federschenkel pressend an die andereSeitenwand zu halten. Bei den bekannten Federleisten sind die Federschenkel an gegenüberliegendenSeitenwänden der Führnngsnuten angeordnet. Dies führt dazu, daß permanent ein Drehmomentauf die Leiterplatte ausgeübt wird, unter dessen Einfluß die Leiterplatte schräggestellt ist, was Kontaktschwierigkeiten ergibt.It is known that these spring slats are pushed into the support stripsPrinted circuit boards to avoid a clinking effect by on one side wall eachCurved guide groovesSpring legs pressing against the otherTo hold sidewall. In the known spring strips, the spring legs are on opposite sidesSide walls of the guide grooves arranged. This leads to a permanent torqueis exerted on the circuit board, under the influence of which the circuit board is inclinedis posed, which results in contact difficulties.
Die Erfindung hat zur Aufgabe unter AusschluB dieses Mangels Maßnahmenzur kippfreien planparallelen Halterung von Leiterplatten in Federleisten dieserArt zu schaffen.The object of the invention is to take measures to rule out this deficiencyfor tilt-free, plane-parallel mounting of printed circuit boards in spring stripsKind of creating.
Der Erfindung gemäß ist dies dadurch erreicht, daß die Stützleistenin den Seitenwänden der Führungsnuten einander gegenüberliegend zwei freie Wandabschnitteaufweisen und daß die Wandabschnitte bogenförmig federnd elastisch über Teilbreitender Führungsnuten in diese einragen. Die pressend zu beiden Seiten, insbesonderemit gleicher Vorspannung an die Leiterplatten anliegenden Wandabschnitte haltendie Leiterplatte klirrfrei parallel zentriert in der Federleiste.According to the invention this is achieved in that the support stripstwo free wall sections opposite one another in the side walls of the guide grooveshave and that the wall sections arcuate resiliently elastic over partial widthsthe guide grooves protrude into this. The pressing on both sides, in particularHold the wall sections adjacent to the circuit boards with the same preloadthe circuit board is centered parallel and without distortion in the socket strip.
Es entspricht der Erfindung die Stützleisten an einer einzigen Stellemit freien federnd elastischen Wandabschnitten zu versehen oder jede Stützleistemit mehreren, z.B. in mindestens zwei im Abstand übereinander sich erstreckendenBereichen mit diesen Wandabschnitten auszurüsten.It corresponds to the invention, the support strips at a single pointto be provided with free resiliently elastic wall sections or any support stripwith several, e.g. at least two spaced one above the otherEquip areas with these wall sections.
Zur Erzielung günstiger Federungseigenschaften ist weiter vorgesehen,die Wandabschnitte mit zu den die Führungsnuten begrenzenden Wänden mit geringerBreite und bevorzugt zu der Führungsnut geringerer Tiefe auszubilden. Nach weitererAusführung ist eine einfache Anordnung der Wandabschnitte durch auf den einanderabgewandten Seiten der Stützleisten eingebrachte Ausnehmungen erreichbar. In order to achieve favorable suspension properties, it is also provided thatthe wall sections with the walls delimiting the guide grooves with lessForm width and preferably to the guide groove of lesser depth. After anotherExecution is a simple arrangement of the wall sections by on top of each otherremote sides of the support strips introduced recesses reachable.
Die Erfindung ist in der Zeichnung an einem Ausführungsbeispiel erläutert.Es zeigen: Fig. 1 eine Federleiste perspektivisch, Fig. 2 eine Federleiste im Schnittnach der Linie IIr- ilt der Fig. 1, Fig. 3 ein Teilstück einer Federleiste in Draufsichtund Fig. 4 einen Teilschnitt einer Federleiste.The invention is explained in the drawing using an exemplary embodiment.The figures show: FIG. 1 a spring strip in perspective, FIG. 2 a spring strip in sectionaccording to the line IIr- ilt of Fig. 1, Fig. 3 a section of a spring strip in plan viewand FIG. 4 shows a partial section of a spring strip.
In den Figuren ist mit 1 ein Leistenkörper bezeichnet, der in an sichbekannter Weise im Bereich einer Ausnehmung 2 mit Verbreiterungen 3 Anschlußfedern4 aufnimmt, die mit Anschlußfahnen die Unterseite des Leistenkörpers 1 überragen.Der Leistenkörper 1 weist Stützleisten 5 auf, die in Führungsnuten 6 eine mit denAnschlußfedern kontaktierende Leiterplatte 7 abstützen. In der eingeschobenen Arbeitsstellung istdie Leiterplatte 7 durch Rastnasen 8 übergriffen und fixiert. Die Stützleisten 5sind im Abstand des Leistenkörpers 1 auf den einander abgewandten Seiten mit einerAusnehmung 9 versehen, die jeweils durch zwei freie Wandabschnitte 10 übergriffensind. Die Wandabschnitte 10 sind bogenförmig zueinander gekrümmt und ragen federndelastisch über gleiche Teilbreiten in die Führungsnuten 6 ein. Beim Einschiebender Leiterplatte 7 in die Führungsnuten 6 der Stützleisten 5 läuft die Leiterplatte7 zunächst an die Wandabschnitte 10 an und biegt bei weiterem Einschieben dieseunter dem Einfluß einer quer zur Einsteckrichtung wirkenden Komponente der Steckkraftnach außen. Die Wandabschnitte 10 üben dabei eine permanente Stützkraft auf dieLeiterplatte 7 aus, die diese in den Führungsnuten 6 mittig zentriert.In the figures, 1 denotes a strip body, which in itselfknown manner in the area of a recess 2 with widenings 3 connecting springs4 receives, which protrude beyond the underside of the strip body 1 with terminal lugs.The strip body 1 has support strips 5, which are in guide grooves 6 with theSupport connecting springs contacting printed circuit board 7. In the retracted working positionisthe circuit board 7 overlapped and fixed by locking lugs 8. The support strips 5are at a distance of the strip body 1 on the opposite sides with aRecess 9 is provided, each of which is overlapped by two free wall sections 10are. The wall sections 10 are curved towards one another in an arc shape and protrude resilientlyelastically over the same partial widths into the guide grooves 6. When pushing inthe circuit board 7 in the guide grooves 6 of the support strips 5 runs the circuit board7 first of all on the wall sections 10 and bends them as they are pushed in furtherunder the influence of a component of the insertion force acting transversely to the insertion directionoutward. The wall sections 10 exercise a permanent supporting force on thePrinted circuit board 7, which centers it in the middle in the guide grooves 6.
