Description
FederleisteFemale connector
Die Erfindung betrifft eine Federleiste, insbesondere für die steckbare Aufnahme von Leiterplatten od.dgl. mit einem Kontaktfedern aufnehmenden Leistenkörper und 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-in Recording of circuit boards or the like. with a strip body receiving contact springs and 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 eingeschobenen Leiterplatten zur Vermeidung eines Klirreffekts durch an einer Seitenwand jeder Führungsnuten eingebogene Federschenkel pressend an die andere Seitenwand zu halten. Bei den bekannten Federleisten sind die Federschenkel an gegenüberliegenden Seitenwänden der Führnngsnuten angeordnet. Dies führt dazu, daß permanent ein Drehmoment auf die Leiterplatte ausgeübt wird, unter dessen Einfluß die Leiterplatte schräg gestellt ist, was Kontaktschwierigkeiten ergibt.It is known that these spring slats are pushed into the support strips Printed circuit boards to avoid a clinking effect by on one side wall each Curved guide grooves Spring legs pressing against the other To hold sidewall. In the known spring strips, the spring legs are on opposite sides Side walls of the guide grooves arranged. This leads to a permanent torque is exerted on the circuit board, under the influence of which the circuit board is inclined is posed, which results in contact difficulties.
Die Erfindung hat zur Aufgabe unter AusschluB dieses Mangels Maßnahmen zur kippfreien planparallelen Halterung von Leiterplatten in Federleisten dieser Art zu schaffen.The object of the invention is to take measures to rule out this deficiency for tilt-free, plane-parallel mounting of printed circuit boards in spring strips Kind of creating.
Der Erfindung gemäß ist dies dadurch erreicht, daß die Stützleisten in den Seitenwänden der Führungsnuten einander gegenüberliegend zwei freie Wandabschnitte aufweisen und daß die Wandabschnitte bogenförmig federnd elastisch über Teilbreiten der Führungsnuten in diese einragen. Die pressend zu beiden Seiten, insbesondere mit gleicher Vorspannung an die Leiterplatten anliegenden Wandabschnitte halten die Leiterplatte klirrfrei parallel zentriert in der Federleiste.According to the invention this is achieved in that the support strips two free wall sections opposite one another in the side walls of the guide grooves have and that the wall sections arcuate resiliently elastic over partial widths the guide grooves protrude into this. The pressing on both sides, in particular Hold the wall sections adjacent to the circuit boards with the same preload the circuit board is centered parallel and without distortion in the socket strip.
Es entspricht der Erfindung die Stützleisten an einer einzigen Stelle mit freien federnd elastischen Wandabschnitten zu versehen oder jede Stützleiste mit mehreren, z.B. in mindestens zwei im Abstand übereinander sich erstreckenden Bereichen mit diesen Wandabschnitten auszurüsten.It corresponds to the invention, the support strips at a single point to be provided with free resiliently elastic wall sections or any support strip with several, e.g. at least two spaced one above the other Equip areas with these wall sections.
Zur Erzielung günstiger Federungseigenschaften ist weiter vorgesehen, die Wandabschnitte mit zu den die Führungsnuten begrenzenden Wänden mit geringer Breite und bevorzugt zu der Führungsnut geringerer Tiefe auszubilden. Nach weiterer Ausführung ist eine einfache Anordnung der Wandabschnitte durch auf den einander abgewandten Seiten der Stützleisten eingebrachte Ausnehmungen erreichbar. In order to achieve favorable suspension properties, it is also provided that the wall sections with the walls delimiting the guide grooves with less Form width and preferably to the guide groove of lesser depth. After another Execution is a simple arrangement of the wall sections by on top of each other remote 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 Schnitt nach der Linie IIr- ilt der Fig. 1, Fig. 3 ein Teilstück einer Federleiste in Draufsicht und 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 section according to the line IIr- ilt of Fig. 1, Fig. 3 a section of a spring strip in plan view and FIG. 4 shows a partial section of a spring strip.
In den Figuren ist mit 1 ein Leistenkörper bezeichnet, der in an sich bekannter Weise im Bereich einer Ausnehmung 2 mit Verbreiterungen 3 Anschlußfedern 4 aufnimmt, die mit Anschlußfahnen die Unterseite des Leistenkörpers 1 überragen. Der Leistenkörper 1 weist Stützleisten 5 auf, die in Führungsnuten 6 eine mit den Anschlußfedern kontaktierende Leiterplatte 7 abstützen. In der eingeschobenen Arbeitsstellung ist die Leiterplatte 7 durch Rastnasen 8 übergriffen und fixiert. Die Stützleisten 5 sind im Abstand des Leistenkörpers 1 auf den einander abgewandten Seiten mit einer Ausnehmung 9 versehen, die jeweils durch zwei freie Wandabschnitte 10 übergriffen sind. Die Wandabschnitte 10 sind bogenförmig zueinander gekrümmt und ragen federnd elastisch über gleiche Teilbreiten in die Führungsnuten 6 ein. Beim Einschieben der Leiterplatte 7 in die Führungsnuten 6 der Stützleisten 5 läuft die Leiterplatte 7 zunächst an die Wandabschnitte 10 an und biegt bei weiterem Einschieben diese unter dem Einfluß einer quer zur Einsteckrichtung wirkenden Komponente der Steckkraft nach außen. Die Wandabschnitte 10 üben dabei eine permanente Stützkraft auf die Leiterplatte 7 aus, die diese in den Führungsnuten 6 mittig zentriert.In the figures, 1 denotes a strip body, which in itself known manner in the area of a recess 2 with widenings 3 connecting springs 4 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 the Support connecting springs contacting printed circuit board 7. In the retracted working position is the circuit board 7 overlapped and fixed by locking lugs 8. The support strips 5 are at a distance of the strip body 1 on the opposite sides with a Recess 9 is provided, each of which is overlapped by two free wall sections 10 are. The wall sections 10 are curved towards one another in an arc shape and protrude resiliently elastically over the same partial widths into the guide grooves 6. When pushing in the circuit board 7 in the guide grooves 6 of the support strips 5 runs the circuit board 7 first of all on the wall sections 10 and bends them as they are pushed in further under the influence of a component of the insertion force acting transversely to the insertion direction outward. The wall sections 10 exercise a permanent supporting force on the Printed circuit board 7, which centers it in the middle in the guide grooves 6.
