Description
Al 404 773 BAl 404 773 B.
Die Erfindung betrifft eine Steckkontaktklemme für eine Schaltungsplatte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a plug contact terminal for a circuit board according to the preamble of claim 1.
Eine derartige Steckkontaktklemme ist aus der DD-156750 A bekannt. Bei dieser bekannten Steckkontaktklemme ist ein im wesentlichen U-förmiges Klemmkontaktstück vorgesehen, welches einen Fußabschnitt, einen über diesem angeordneten Widerlagerabschnitt und einen diese beiden Abschnitte verbindenden Hauptabschnitt aufweist. Zwischen dem Fußabschnitt und dem Widerlagerabschnitt ist eine im wesentlichen U-förmige Klemmfeder angeordnet, welche gegen den Fußabschnitt und den Widerlagerabschnitt des Klemmkontaktstücks abgestützt ist. Ferner ist bei dem in einem Gehäuse eingesetzten Klemmkontaktstück die U-Klemmfeder gegen seitliches Verschieben durch an beiden Seiten des Klemmkontaktstücks, und somit der U-Klemmfeder, angeordnete Gehäuseabschnitte gesichert. Diese bekannte Steckkontaktklemme umfaßt ferner einen Entriegelungshebel, der in dem Gehäuse seitlich des Klemmkontaktstücks schwenkbar gelagert ist. Der Entriegelungshebel ragt einerseits aus dem Gehäuse zur Betätigung von außen heraus und drückt andererseits auf den, ein Drahtstück klemmenden Abschnitt der U-Klemmfeder, um die Klemmwirkung zu lösen.Such a plug contact terminal is known from the DD-156750 A. In this known plug contact terminal, an essentially U-shaped terminal contact piece is provided, which has a foot section, an abutment section arranged above this and a main section connecting these two sections. A substantially U-shaped clamping spring is arranged between the foot section and the abutment section and is supported against the foot section and the abutment section of the clamping contact piece. Furthermore, in the clamping contact piece used in a housing, the U-clamping spring is secured against lateral displacement by housing sections arranged on both sides of the clamping contact piece, and thus the U-clamping spring. This known plug contact terminal further comprises an unlocking lever which is pivotally mounted in the housing to the side of the terminal contact piece. On the one hand, the unlocking lever protrudes from the housing for actuation from the outside and, on the other hand, presses on the section of the U-clamping spring that clamps a piece of wire in order to release the clamping effect.
Aus der DE 33 46 027 C ist eine Steckkontaktklemme bekannt, bei welcher das Klemmkontaktstück und die Klemmfeder einteilig durch entsprechendes Biegen eines Blechteils gebildet sind. D.h. ein Abschnitt des Blechteils bildet den Widerlagerabschnitt, und ein Endabschnitt des Blechteils liegt unter einem Winkel an dem Widerlagerabschnitt an und ist bei Einschieben eines Drahts vom Widerlagerabschnitt weg bewegbar, so daß der Draht zwischen dem Endabschnitt und dem Widerlagerabschnitt geklemmt ist.From DE 33 46 027 C a plug contact terminal is known, in which the terminal contact piece and the clamping spring are formed in one piece by corresponding bending of a sheet metal part. I.e. a section of the sheet metal part forms the abutment section, and an end section of the sheet metal part lies at an angle on the abutment section and can be moved away from the abutment section when a wire is inserted, so that the wire is clamped between the end section and the abutment section.
Aus dem deutschen Gebrauchsmuster DE 74 08 006 U ist eine Federdruckklemme bekannt, bei welcher in einem geschlossenen Blechrahmen eine V-förmige Feder eingesetzt ist. Zwischen einem freien Ende der V-förmigen Feder und einer Deckwandung des Blechrahmens kann ein Draht geklemmt werden. Es sind bei dieser Federkontaktklemme jedoch keine Mittel vorgesehen, um den Klemmsitz des Drahts zwischen dem Blechrahmen und der Feder zu lösen.A spring pressure clamp is known from German utility model DE 74 08 006 U, in which a V-shaped spring is inserted in a closed sheet metal frame. A wire can be clamped between a free end of the V-shaped spring and a top wall of the sheet metal frame. In this spring contact clamp, however, no means are provided to release the wire from the sheet metal frame and the spring.
Es ist die Aufgabe der vorliegenden Erfindung, eine Steckkontaktklemme zu schaffen, welche selbst bei dünnen Anschlußleitungen eine hohe Auszugskraft vorsieht. Erfindungsgemäß wird diese Aufgabe durch eine Steckkontaktklemme mit den in Anspruch 1 angegebenen Merkmalen gelöst.It is the object of the present invention to provide a plug contact terminal which provides a high pull-out force even with thin connecting lines. According to the invention, this object is achieved by a plug contact terminal with the features specified in claim 1.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Steckkontaktklemme sind in den Unteransprüchen angegeben.Further advantageous embodiments of the plug contact terminal according to the invention are specified in the subclaims.
Eine besonders einfache und wirksame Befestigung der U-Klemmfeder am Blechteil ist in Anspruch 8 angegeben.A particularly simple and effective attachment of the U-clamp spring to the sheet metal part is specified in claim 8.
Eine besonders einfache Montage bei stabiler Ausführung und bei billiger Herstellung ergibt sich durch die Ausbildung gemäß Anspruch 9.A particularly simple assembly with a stable design and cheap manufacture results from the design according to claim 9.
Die Stabilität wird durch die Ausbildung gemäß Anspruch 10 noch verbessert.The stability is further improved by the training according to claim 10.
Die Erfindung wird im folgenden an einem bevorzugten Ausführungsbeispiel unter Hinweis auf die beigefügten Zeichnungen beschrieben:The invention is described below in a preferred embodiment with reference to the accompanying drawings:

Die zum Aufstecken auf einer Schaltungsplatte vorgesehene Steckkontaktklemme 2 weist ein Gehäuse 4 mit drei Abteilen 6 zur Aufnahme jeweils eines Klemmkontaktstücks 8 auf. Auf die Schaltungsplatte ist eine Bodenwand 10 des Gehäuses 4 aufsetzbar. In der Bodenwand 10 befinden sich für jedes Abteil 6 zwei Durchbrechungen 12, 14 zur Durchführung von zwei von dem Klemmkontaktstück 8 ausgehenden Kontaktstiften 16, 18. In einer Deckwand 20 des Gehäuses 4 befindet sich für jedes Abteil 6 eine trichterförmige Durchbrechung 22 zur Einführung eines Endes 24 einer Anschlußleitung 26 zwischen einen Klemmfederschenkel 28 und einem Widerlagerabschnitt 30 am Klemmkontaktstück 8.The plug contact terminal 2 provided for plugging onto a circuit board has a housing 4 with three compartments 6 for receiving a terminal contact piece 8 in each case. A bottom wall 10 of the housing 4 can be placed on the circuit board. In the bottom wall 10 there are two openings 12, 14 for each compartment 6 for carrying out two contact pins 16, 18 extending from the clamping contact piece 8. In a top wall 20 of the housing 4 there is a funnel-shaped opening 22 for each compartment 6 for the introduction of one end 24 a connecting line 26 between a clamping spring leg 28 and an abutment section 30 on the clamping contact piece 8.
Das Klemmkontaktstück 8 weist ein Blechteil 32 mit einem vertikalen Hauptabschnitt 34 auf, von dem unten zu einer Seite hin ein auf der Bodenwand 10 des Gehäuses 4 aufliegender Fußabschnitt 36 abgebogen ist, auf dem der eine - untere - Schenkel 38 einer sich in Abstand neben dem Hauptabschnitt 34 erstreckenden U-Klemmfeder 40 befestigt ist, von dem oben zur gleichen Seite hin ein den anderen -oberen - Schenkel 28 der U-Klemmfeder 40 übergreifender Widerlagerabschnitt 30 abgebogen ist und von dem zur gleichen Seite hin ein von außen an die Krümmung 42 der U- Klemmfeder 40 angreifender Stützabschnitt 44 abgebogen ist. Der Widerlagerabschnitt 30 hat einen in die Richtung der Einführung der Anschlußleitung 26 weisenden, freien, nachgiebig ausgebildeten Endabschnitt 31, der in einen vertikalen Kanal 71 ragt. Der Kanal 71 ist vertikal und zur Aufnahme eines nicht dargestellten Prüfstifts, der von oben 2The clamping contact piece 8 has a sheet metal part 32 with a vertical main section 34, from which a foot section 36 resting on the bottom wall 10 of the housing 4 is bent down to one side, on which the one - lower - leg 38 one at a distance apart from the Main section 34 extending U-clamp spring 40 is attached, from which an abutment section 30, which overlaps the other - upper - leg 28 of the U-clamp spring 40 and is bent from the top to the same side, and from which to the same side one from the outside to the curvature 42 U-clamping spring 40 engaging support section 44 is bent. The abutment section 30 has a free, flexible end section 31 which points in the direction of the insertion of the connecting line 26 and projects into a vertical channel 71. The channel 71 is vertical and for receiving a test pin, not shown, from above 2
