Description

Die Erfindung betrifft eine Anschlußklemme gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a connecting terminal according to the preamble of claim 1.

Aus DE-U-91 02 953 ist eine Anschlußklemme dieser Gattung bekannt. Bei dieser bekannten Anschlußklemme sind das Leiterschutzelement und der Steckkontakt als einstückiges Blechstanzteil mit einem verbindenden Blechstreifen ausgebildet. Dadurch wird die Herstellung vereinfacht und gesonderte Maßnahmen zur elektrisch leitenden Verbindung des Leiterschutzelementes mit dem Steckkontakt entfallen. Die Leiteraufnahme des Klemmkörpers und der zugeordnete Steckkontakt sind achsparallel nebeneinander in dem Klemmengehäuse angeordnet und von dessen Frontseite zugänglich. Um den Klemmkörper mit dem Blechstanzteil in das Klemmengehäuse einsetzen zu können, muß dieses Klemmengehäuse zumindest aus zwei Gehäuseschalen bestehen. Dies bedeutet einen Herstellungs- und Montageaufwand.From DE-U-91 02 953 a terminal of this type is known. In this known connection terminal, the conductor protection element and the plug contact are designed as a one-piece sheet metal stamped part with a connecting sheet metal strip. This simplifies manufacture and eliminates the need for separate measures for the electrically conductive connection of the conductor protection element to the plug contact. The conductor receptacle of the clamping body and the associated plug contact are arranged in the terminal housing parallel to one another in an axis-parallel manner and are accessible from its front side. In order to be able to insert the clamping body with the stamped sheet metal part into the terminal housing, this terminal housing must consist of at least two housing shells. This means a manufacturing and assembly effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußklemme der genannten Gattung so auszubilden, daß die Herstellung und die Montage weiter vereinfacht und damit kostengünstiger werden.The invention has for its object to provide a terminal of the type mentioned so that the manufacture and assembly further simplified and thus cheaper will.

Diese Aufgabe wird bei einer Anschlußklemme der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils des Anspruchs 1.This object is achieved according to the invention in a connection terminal of the type mentioned at the outset by the features of the characterizing part of claim 1.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Anschlußklemme verläuft die Achse des Steckkontaktes senkrecht zur Achse der Leiteraufnahme und der Steckkontakt ist hinter der der Leiteraufnahme entgegengesetzten Stirnfläche des Klemmkörpers angeordnet. Auf diese Weise kann der Klemmkörper zusammen mit dem das Leiterschutzelement und den Steckkontakt bildenden Blechstanzteil in eine Aussparung des Klemmengehäuses eingesetzt werden. Dies vereinfacht die Herstellung des Klemmengehäuses und die Montage der Anschlußklemme.In the connection terminal according to the invention, the axis of the plug contact runs perpendicular to the axis of the conductor receptacle and the plug contact is arranged behind the end face of the clamping body opposite the conductor receptacle. In this way, the clamping body can be inserted into a recess in the terminal housing together with the sheet-metal stamped part that forms the conductor protection element and the plug contact. This simplifies the manufacture of the terminal housing and the assembly of the connection terminal.

Im allgemeinen wird die Anschlußklemme mehrpolig mit mehreren Klemmkörpern in einem Klemmengehäuse hergestellt. Hierbei ergibt sich eine zusätzliche Vereinfachung der Herstellung und der Montage. Aus dem Stanzstreifen werden die Leiterschutzelemente mit den Kontaktlamellen sämtlicher Pole der Anschlußklemme ausgestanzt, wobei die Blechstanzteile der einzelnen Pole noch über einen Längsstreifen des Stanzstreifens zusammenhängen, der an einer der Kontaktlamellen ansetzt. Es werden dann die freien Schenkel der Leiterschutzelemente U-förmig abgebogen und die Klemmkörper auf die abgebogenen Schenkel aufgeschoben. Nachdem so die Blechstanzteile mit den Klemmkörpern vormontiert sind, wird der verbindende Längsstreifen abgetrennt und die Kontaktlamellen abgebogen, worauf die Klemmkörper mit den Blechstanzteilen in das Klemmengehäuse eingesetzt werden. Es ist somit ein weitgehend automatischer Montagevorgang in einem Montageautomaten möglich.In general, the connection terminal is made multi-pole with several clamp bodies in a terminal housing. This results in an additional simplification of manufacture and assembly. The conductor protection elements with the contact lamellae of all the poles of the connecting terminal are punched out of the stamped strip, the sheet-metal stamped parts of the individual poles still being connected via a longitudinal strip of the stamped strip which attaches to one of the contact lamellae. The free legs of the conductor protection elements are then bent in a U-shape and the clamping bodies are pushed onto the bent legs. After the sheet metal stampings with the clamping bodies are pre-assembled, the connecting longitudinal strip is cut off and the contact lamellae bent, whereupon the clamping bodies with the sheet metal stampings are inserted into the terminal housing. It is therefore a largely automatic assembly process possible in an automatic assembly machine.

In einer bevorzugten Ausführungsform ist die Kante der hinteren Stirnfläche des Klemmkörpers als Biegekante ausgebildet, über welche die Kontaktlamellen von dem Leiterschutzelement abgebogen werden. Zweckmäßigerweise ist die hintere Stirnfläche so abgeschrägt, daß die Kontaktlamellen über diese Biegekante um einen Winkel von mehr als 90° abgebogen werden können. Aufgrund der bei dem Abbiegen verbleibenden Restelastizität nehmen die Kontaktlamellen dann nach der Freigabe spannungsfrei den gewünschten Biegewinkel von 90° ein.In a preferred embodiment, the edge of the rear end face of the clamping body is designed as a bending edge, via which the contact blades are bent by the conductor protection element. The rear end face is expediently beveled in such a way that the contact lamellae can be bent over an angle of more than 90 ° over this bending edge. Due to the residual elasticity remaining during the bending, the contact lamellae then take up the desired bending angle of 90 ° without tension after the release.

In dem in der Zeichnung dargestellten Ausführungsbeispiel ist die Anschlußklemme als fünfpolige Anschlußklemme ausgebildet. In einem Kunststoffklemmengehäuse 10 sind stirnseitig fünf Aussparungen nebeneinander angeordnet, in welche jeweils ein metallischer, vorzugsweise im Druckgußverfahren hergestellter Klemmkörper 12 eingesetzt ist. Die Klemmkörper 12 weisen stirnseitig eine Leiteraufnahme 14 auf, die als Sackloch ausgebildet ist. Senkrecht zur Achse der Leiteraufnahme 14 führt jeweils von oben durch den Klemmkörper 12 in die Leiteraufnahme 14 eine Gewindebohrung, in welche eine zylindrische Klemmschraube 16 einschraubbar ist, welche unverlierbar in dem Klemmengehäuse 10 gehalten ist.In the embodiment shown in the drawing, the connection terminal is designed as a five-pole connection terminal. In a plastic clamp housing 10, five cutouts are arranged side by side in the front, in each of which a metallic clamp body 12, preferably produced by the die casting process, is inserted. The clamping bodies 12 have a conductor receptacle 14 on the end face, which is designed as a blind hole. Perpendicular to the axis of the conductor receptacle 14, a threaded bore leads from above through the clamping body 12 into the conductor receptacle 14, into which a cylindrical clamping screw 16 can be screwed, which is held captively in the terminal housing 10.

Hinter den Aussparungen für die Klemmkörper 12 sind in dem Klemmengehäuse 10 jeweils senkrecht zur Achse der Leiteraufnahme 14 verlaufende Buchsen 18 angeordnet, die hinter der von der Leiteraufnahme 14 abgewandten hinteren Stirnfläche der eingesetzten Klemmkörper 12 in dem Klemmengehäuse 10 verlaufen.Behind the cutouts for the clamping bodies 12, bushes 18 are arranged in the terminal housing 10, each perpendicular to the axis of the conductor receptacle 14, which run behind the rear end face of the inserted clamping bodies 12 facing away from the conductor receptacle 14 in the terminal housing 10.

Jedem Klemmkörper 12 ist ein Blechstanzteil zugeordnet, wie es in den Figuren 5 und 6 dargestellt ist. Die Blechstanzteile weisen ein streifenförmiges langgestrecktes Leiterschutzelement 20 auf, welches einen kreisförmigen Durchbruch 22 für die Klemmschraube 16 aufweist und dessen freier Schenkel 24 U-förmig abgebogen ist. Der freie Schenkel 24 greift stirnseitig in die Leiteraufnahme 14 ein, während das Leiterschutzelement 20 mit seinem Durchbruch 22 so oben auf dem Klemmkörper 12 aufliegt, daß der Durchbruch 22 mit der Gewindebohrung des Klemmkörpers 12 zur Deckung kommt.A sheet metal stamped part is assigned to each clamping body 12, as shown in FIGS. 5 and 6. The sheet metal stampings have a strip-shaped, elongated conductor protection element 20, which has a circular opening 22 for the clamping screw 16 and the free leg 24 is bent in a U-shape. The free leg 24 engages in the end of the conductor receptacle 14, while the conductor protection element 20 rests with its opening 22 on top of the clamping body 12 in such a way that the opening 22 coincides with the threaded bore of the clamping body 12.

An das Leiterschutzelement 20 einstückig anschließend weist das Blechstanzteil drei Kontaktlamellen 26, 28 auf. Die Kontaktlamellen 26, 28 sind parallel zueinander angeordnet, wobei die beiden äußeren Kontaktlamellen 28 jeweils über einen Quersteg 30 mit der mittleren Kontaktlamelle 26 zusammenhängen. Die mittlere Kontaktlamelle 26 ist als fluchtende Fortsetzung des Leiterschutzelementes 20 einstückig mit diesem verbunden. Die mittlere Kontaktlamelle 26 ist rechtwinklig gegen das Leiterschutzelement 20 abgebogen. Die Querstege 30 der beiden seitlichen Kontaktlamellen 28 sind so gegen die mittlere Kontaktlamelle 26 abgebogen, daß die drei Kontaktlamellen 26 und 28 im wesentlichen einen Aufnahmequerschnitt in Form eines gleichseitigen Dreiecks einschließen, wie am besten in Figur 5 zu erkennen ist. Ist der Klemmkörper 12 mit dem Blechstanzteil in das Klemmengehäuse 10 eingesetzt, so befinden sich die Kontaktlamellen 26, 28 in der Buchse 18, wobei ihr dreieckiger Aufnahmequerschnitt koaxial mit der Bohrung 18 ausgerichtet ist. Wird ein Steckerstift 32 in die Buchse 18 eingesteckt, so wird er daher in den Aufnahmequerschnitt der Kontaktlamellen 26, 28 geschoben, wie in Figur 5 strichpunktiert eingezeichnet ist, wobei die elastische Federkraft der Querstege 30 den Kontaktdruck zwischen den Kontaktlamellen 26, 28 und dem Steckerstift 32 erzeugt.Adjoining the conductor protection element 20 in one piece, the sheet metal stamped part has three contact blades 26, 28. The contact blades 26, 28 are arranged parallel to one another, the two outer contact blades 28 each being connected to the central contact blade 26 via a crosspiece 30. The middle contact lamella 26 is integrally connected to the conductor protection element 20 as an aligned continuation. The middle contact lamella 26 is bent at right angles to the conductor protection element 20. The transverse webs 30 of the two lateral contact lamellae 28 are bent against the central contact lamella 26 such that the three contact lamellae 26 and 28 essentially enclose a receiving cross section in the form of an equilateral triangle, as can best be seen in FIG. If the clamping body 12 with the stamped sheet metal part is inserted into the terminal housing 10, the contact blades 26, 28 are located in the socket 18, their triangular receiving cross section being aligned coaxially with the bore 18. If a plug pin 32 is inserted into the socket 18, it is therefore pushed into the receiving cross-section of the contact lamellae 26, 28, as shown in dash-dotted lines in FIG 32 generated.

Zur Herstellung werden von einem Stanzstreifen in einem Stanzvorgang die Blechstanzteile sämtlicher Pole einer Anschlußklemme ausgestanzt, wobei die Blechstanzsteile der einzelnen Pole noch über einen Längsstreifen 34 miteinander in Verbindung stehen, der an der mittleren Kontaktlamelle 26 ansetzt, wie dies in Figur 7 gezeigt ist. Die über den Längsstreifen 34 zusammenhängenden Blechstanzteile werden in einen Automaten eingelegt, in welchem zunächst längs der in Figur 7 gestrichelt eingezeichneten Kanten 36 die freien Schenkel 24 der Leiterschutzelemente 20 abgebogen werden. Auf diese freien Schenkel 24 werden dann die Klemmkörper 12 aufgeschoben. In einem folgenden Arbeitsschritt werden die seitlichen Kontaktlamellen 28 um die Kanten 38 gegen die mittlere Kontaktlamelle 26 gebogen. Dann werden die mittleren Kontaktlamellen 26 gegenüber dem Leiterschutzelement 20 nach unten um die Kante 40 abgebogen. Zum Abbiegen der mittleren Kontaktlamelle 26 um die Kante 40 dient die obere Kante der hinteren Stirnfläche 42 der Klemmkörper 12 als Biegekante. Die hintere Stirnfläche 42 der Klemmkörper 12 ist hierzu gegen die zur Achse der Leiteraufnahme 14 senkrechte Ebene um einen Winkel von 10° abgeschrägt, wie Figur 4 zeigt. Dadurch ist es möglich, die mittleren Kontaktlamellen 26 um die hintere Oberkante der Klemmkörper 12 über einen Winkel von mehr als 90° abzubiegen. Gibt das Biegewerkzeug die Kontaktlamellen 26 nach dem Biegevorgang frei, so lösen sich diese wieder aufgrund ihrer Restelastizität von der hinteren Stirnfläche 42 der Klemmkörper 12 und nehmen (dann spannungsfrei) eine zu dem Leiterschutzelement 20 senkrechte Stellung ein, wie dies in Figur 2 zu sehen ist. Durch das Abwinkeln der mittleren Kontaktlamelle 26 werden die Klemmkörper 12 auf den freien Schenkeln 24 der Leiterschutzelemente 20 festgehalten und die Klemmkörper 12 mit den Blechstanzteilen können nach Abtrennen des Längsstreifens 34 längs der Stanzlinie 44 in das Klemmengehäuse 10 eingesetzt werden.For the production of a stamped strip in a stamping process, the sheet metal stamped parts of all poles one The terminal is stamped out, the stamped sheet metal parts of the individual poles still being connected to one another via a longitudinal strip 34 which attaches to the central contact lamella 26, as shown in FIG. The sheet metal stampings connected via the longitudinal strips 34 are placed in an automatic machine in which the free legs 24 of the conductor protection elements 20 are first bent along the edges 36 shown in broken lines in FIG. The clamping bodies 12 are then pushed onto these free legs 24. In a subsequent step, the side contact lamella 28 are bent around the edges 38 against the middle contact lamella 26. Then the middle contact lamellae 26 are bent downward around the edge 40 relative to the conductor protection element 20. The upper edge of the rear end face 42 of the clamping body 12 serves as a bending edge for bending the middle contact lamella 26 around the edge 40. For this purpose, the rear end face 42 of the clamping body 12 is chamfered by an angle of 10 ° with respect to the plane perpendicular to the axis of the conductor receptacle 14, as shown in FIG. 4. This makes it possible to bend the middle contact lamellae 26 around the rear upper edge of the clamping body 12 over an angle of more than 90 °. If the bending tool releases the contact lamellae 26 after the bending process, these loosen again due to their residual elasticity from the rear end face 42 of the clamping bodies 12 and assume a position perpendicular to the conductor protection element 20 (then without tension), as can be seen in FIG. 2 . By angling the middle contact lamella 26, the clamping bodies 12 are held on the free legs 24 of the conductor protection elements 20 and the clamping bodies 12 with the stamped sheet metal parts can be inserted into the terminal housing 10 after the longitudinal strip 34 has been cut off along the punching line 44.
