Abstract

An electrical terminal clamp for a screw terminal with a baseplate, having a passage for a clamping element, on which there are seated anchoring limbs, which are bent at right angles and lie opposite parallel to one another, for holding a spring clamping disc, and with supporting webs projecting at right angles on opposite sides of the baseplate. The technical problem is the provision of a screw terminal clamp which can easily be attached to pegs in housings, especially terminal housings. Each anchoring limb (4) terminates in two tongues (7), each having mutually opposite slots (8). The spring clamping disc (12) is inserted in these slots. The end-face side wall (9) of each slot (8) is pressed onto the spring clamping disc (12). <IMAGE>

Description

Die Erfindung betrifft eine elektrische Anschlußklemme für einen Schraubanschluß mit einer einen Durchgang für ein Spannelement aufweisenden Grundplatte, an der rechtwinklig abgebogene und einander parallel gegenüberstehende Verankerungsschenkel zur Aufnahme einer Federklemmscheibe sitzen, und mit an gegenüberliegenden Seiten der Grundplatte senkrecht aufstehenden Anlagestegen.The invention relates to an electrical connection terminal for a screw connection with a passage for a tensioning element base plate, on which angled anchoring legs, which are bent at right angles and parallel to one another, for receiving a spring clamp washer, and with contact webs standing upright on opposite sides of the base plate.

Eine elektrische Anschlußklemme dieser Gattung ist aus der DE-U-1 947 175 bekannt. Diese Anschlußklemme ist für eine Montage auf Schienen ausgebildet. Für eine Montage auf Anschlußzapfen ist diese Anschlußklemme nicht geeignet.An electrical terminal of this type is known from DE-U-1 947 175. This terminal is designed for mounting on rails. This terminal is not suitable for mounting on connecting pins.

Aufgabe der Erfindung ist die Bereitstellung einer Schraubanschlußklemme, die in einfacher Weise an Zapfen in Gehäusen, insbesondere Anschlußgehäusen befestigt werden kann.The object of the invention is to provide a screw terminal which can be easily attached to pins in housings, in particular connection housings.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß jeder Verankerungsschenkel in zwei Zungen ausläuft, die jeweils einander gegenüberstehende Schlitze aufweisen, daß die Federklemmscheibe in diese Schlitze eingelegt ist und daß die stirnseitige Seitenwand jedes Schlitzes an die Federklemmscheibe angedrückt ist.This object is achieved according to the invention in that each anchoring leg ends in two tongues, each having mutually opposed slots, that the spring washer is inserted into these slots and that the front side wall of each slot is pressed against the spring washer.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die die Federklemmscheibe haltenden Verankerungsschenkel einen ausreichenden Raum für die Aufnahme des Zapfens und zur Unterbringung des Schaftes des Spannelementes für den Leiterdraht umschließen. Die Schraubanschlußklemme besteht aus einem schmalen Blechzuschnitt gleichmäßiger Breite, so daß die Fertigungskosten und Werkstoffkosten klein gehalten werden können. Die Federklemmscheibe wird in den Schlitzen unverlierbar festgeklemmt und beim Aufdrücken festgehalten, so daß eine einwandfreie Montage gewährleistet ist.The invention differs from the prior art in that the anchoring legs holding the spring clamping disk enclose sufficient space for receiving the pin and for accommodating the shaft of the tensioning element for the conductor wire. The screw terminal consists of a narrow sheet metal blank of uniform width, so that the manufacturing and material costs can be kept low. The spring washer is in the Slits are captively clamped and held when they are pressed on, so that perfect assembly is guaranteed.

Der Werkstoffbedarf wird dadurch besomders klein gehalten, daß der Durchgang als Gewindedurchgang ausgebildet ist, daß die Verankerungsschenkel jeweils im Anschluß an die Grundplatte einen Freischnitt aufweisen und daß der freigeschnittene Lappen als Anlagesteg abgebogen ist.The material requirement is kept particularly small in that the passage is designed as a threaded passage, that the anchoring legs each have a free cut in connection with the base plate and that the cut-out tab is bent as a contact web.

Der Platzbedarf für die Anschlußklemme läßt sich dadurch klein halten, daß der Verankerungsschenkel selbst als Anlageschenkel dient und daß eine durch den Durchgang reichende Schraube eine Mutter trägt. Damit erfolgt die Klemmung der Leiterdrähte an den Verankerungsschenkeln.The space required for the connecting terminal can be kept small by the fact that the anchoring leg itself serves as a contact leg and that a screw reaching through the passage carries a nut. The conductor wires are then clamped to the anchoring legs.

Ausführungsformen der Erfindung werden im Folgenden unter Bezugnahme auf die anliegende Zeichnung erläutert, in der darstellen:

a section through a modified embodiment.

Der ebene Blechzuschnitt weist in einer Grundplatte 1 einen gezogenen, hülsenförmigen Durchgang 2 mit einem Gewinde 3 auf. An die Grundplatte 1 schließen sich Verankerungsschenkel 4 an, die jeweils einen fensterartigen Freischnitt 5 aufweisen, wobei der freigeschnittene und abgebogene Lappen als Anlagesteg 6 der fertigen Anschlußklemme dient. Die Enden der Verankerungsschenkel 4 laufen in einander gegenüberstehende Zungen 7 aus, die jeweils aufeinander ausgerichtete, einander gegenüberstehende Schlitze 8 aufweisen. Die stirnseitige Seitenwand 9 jedes Schlitzes ist vergleichsweise schmal.The flat sheet metal blank has a drawn, sleeve-shaped passage 2 with a thread 3 in a base plate 1. Anchoring legs 4 adjoin the base plate 1, each of which has a window-like free cut 5, the cut and bent tab serving as a contact web 6 of the finished connecting terminal. The ends of the anchoring legs 4 end in mutually opposing tongues 7, each of which have mutually aligned, opposing slots 8. The front side wall 9 of each slot is comparatively narrow.

Der Blechzuschnitt nach Fig. 1 wird in üblicher Weise aus einem Blechstreifen gestanzt. Die Breite des Blechzuschnittes ist überall im wesentlichen gleichbleibend und entspricht der Breite der Verankerungsschenkel.1 is punched out of a sheet metal strip in the usual way. The width of the sheet metal blank is essentially constant everywhere and corresponds to the width of the anchoring legs.

Zur fertigen Anschlußklemme werden die Verankerungsschenkel 4 gegenüber der Grundplatte 1 an den Faltlinien 10 rechtwinklig umgebogen. Die Anlagestege werden an den Faltlinien 11 ebenfalls rechtwinklig umgebogen. jedoch in entgegengesetzter Richtung zu den Verankerungsschenkeln 4, so daß bei der Anschlußklemme die Verankerungsschenkel 4 und die Anlagestege 6 im wesentlichen parallel zueinander ausgerichtet sind, wie man insbesondere aus Fig. 3 erkennt.For the finished terminal, the anchoring legs 4 are bent at right angles to the base plate 1 at the fold lines 10. The contact webs are also bent at right angles on the fold lines 11. however in the opposite direction to the anchoring legs 4, so that the anchoring legs 4 and the contact webs 6 are aligned essentially parallel to one another at the connecting terminal, as can be seen in particular from FIG. 3.

Die Schlitze 8 nehmen eine Federklemmscheibe 12 auf, die aus einem Federband ausgeschnitten und geformt wird. Diese Federklemmscheibe 12 läßt sich bei der Herstellung der Anschlußklemme automatisch in die Schlitze 8 einführen. Zur Halterung der Federklemmscheibe werden die Seitenwände 9 in Pfeilrichtung 13 angedrückt, so daß die Federklemmscheibe 12 in den Schlitzen 8 fest eingeklemmt ist. Die schmalen Seitenwände lassen sich leicht verformen.The slots 8 receive a spring washer 12 which is cut out of a spring band and shaped. This spring washer 12 can be automatically inserted into the slots 8 in the manufacture of the terminal. To hold the spring washer, the side walls 9 are pressed in the direction of arrow 13, so that the spring washer 12 is firmly clamped in the slots 8. The narrow side walls can be easily deformed.

Die Anschlußklemme wird nach Fig. 3 mit der Federklemmscheibe 12 auf einen Zapfen 15 oder einen anderen Ansatz eines Gehäuses oder einer Tragplatte 16 aufgedrückt und so befestigt. Die Federklemmscheibe 12 wirkt in bekannter Weise. Die Verankerungsschenkel 4 haben eine ausreichende Länge, damit einerseits der Zapfen 15 und andererseits der Fuß einer in das Gewinde 3 einzuschraubenden Anschlußschraube 14 Platz finden, ohne daß Behinderungen auftreten. Die Anschlußschraube 14 wird in das Gewinde 3 eingeschraubt und klemmt in üblicher Weise Leiterdrähte 17 fest. Die Lage der Leiterdrähte wird durch die Anlagestege 6 fixiert, damit die Leiterdrähte nicht unter dem Kopf der Anschlußschraube 14 heraustreten können.The terminal is pressed according to Fig. 3 with the spring washer 12 on a pin 15 or another approach of a housing or a support plate 16 and fastened in this way. The spring washer 12 acts in a known manner. The anchoring legs 4 have a sufficient length so that on the one hand the pin 15 and on the other hand the foot of a screw 14 to be screwed into the thread 3 can be accommodated without any hindrances occurring. The connecting screw 14 is screwed into the thread 3 and clamps conductor wires 17 in the usual way. The position of the conductor wires is fixed by the contact webs 6 so that the conductor wires cannot come out from under the head of the connecting screw 14.

Fig. 5 zeigt eine abgewandelte Ausführungsform. Dort sind die Verankerungsschenkel 4′ gleichzeitig Anlagestege. Durch den gewindefreien Durchgang 2 reicht der Schaft der Anschlußschraube 14 hindurch. Auf dem Gewinde der Anschlußschraube 14 sitzt eine Vierkantmutter 21, die verdrehungsfrei zwischen den Verankerungsschenkeln 4′ geführt ist. Die Leiterdrähte 17 sind in bekannter Weise festgeklemmt.Fig. 5 shows a modified embodiment. There are the anchoring legs 4 'at the same time landing stages. The shaft of the connecting screw 14 extends through the thread-free passage 2. On the thread of the connecting screw 14 sits a square nut 21, which is guided between the anchoring legs 4 'without rotation. The conductor wires 17 are clamped in a known manner.
