Description

Die Erfindung betrifft eine Anschlußklemme gemäß dem Oberbegriff des Anspruches 1 und ein Verfahren zur Herstellung der Anschlußklemme.The invention relates to a connecting terminal according to the preamble of claim 1 and a method for producing the connecting terminal.

Derartige Anschlußklemmen sind in großer Vielzahl bekanntgeworden. Beispielsweise ist eine Anschlußklemme der eingangs genannten Art durch die DE-OS 31 37 117 bzw. 31 08 9b5. Bei derartigen Klemmen sind zwei ineinanderlaufende Klemmenkästen vorhanden, von denen der eine Kasten mit der Zuleitung ins Schalterinnere verbunden ist und als Führung des anderen Klemmenkastens dient. Der erste Klemmenkasten hat außerdem einen Steg an der Unterseite, der zur Anlage und Kontaktgabe für die angeschlossenen Leiter bei Anschluß im Kastenrahmen der Klemme dient.A large number of such terminals have become known. For example, a connector of the type mentioned by DE-OS 31 37 117 and 31 08 9b5. Such terminals have two terminal boxes running one inside the other, one of which is connected to the supply line to the inside of the switch and serves as a guide for the other terminal box. The first terminal box also has a web on the underside, which is used for contacting and making contact with the connected conductors when connected in the box frame of the terminal.

Aufgrund des Ineinanderfügens der beiden Klemmenkästen muß die Montage vor bzw. bei dem Fertigbiegen des ersten Klemmenkastens vorgenommen werden, was relativ kompliziert und zeitaufwendig ist und eine automatische Montage praktisch ausschließt. Darüberhinaus muß der erste Klemmenkasten aus einer Kupferlegierung hergestellt sein; aufgrund der Gestaltung der Klemme wird relativ viel Material (Kupfer) benötigt.Due to the merging of the two terminal boxes, assembly must be carried out before or during the final bending of the first terminal box, which is relatively complicated and time-consuming and virtually precludes automatic assembly. In addition, the first terminal box must be made of a copper alloy; Due to the design of the clamp, a relatively large amount of material (copper) is required.

Aufgabe der Erfindung ist es, eine Anschlußklemme der eingangs genannten Art zu schaffen, die materialarm und einfach in der Herstellung und Montage ist.The object of the invention is to provide a terminal of the type mentioned, which is low in material and easy to manufacture and assemble.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen 2 bis 3 zu entnehmen.Further advantageous refinements of the invention can be found in subclaims 2 to 3.

Die Herstellung der Anschlußklemme erfolgt nach dem Verfahren gemäß dem Anspruch 4.The connection terminal is produced by the method according to claim 4.

Dadurch, daß der erste Klemmenkasten nicht mehr als geschlossener Kastenrahmen sondern U-förmig ausgebildet und zur Schalterinnenseite offen ist, und daß erst durch den Stegabschnitt der Lichtbogenleitschiene der U-förmige Teil zum gesamten Kastenrahmen bzw. Klemmenrahmen ergänzt wird, daß also ein zusätzliches Abstützelement vorgesehen wird, mit dem dann der erste Klemmenkasten zu einem praktisch geschlossenen Rahmen ergänzt wird, können beide Klemmenkästen unabhängig voneinander gefertigt und miteinander kombiniert werden; es ist dann nur noch erforderlich, den zweiten Klemmenkasten über den unteren Quersteg des ersten Klemmenkastens zu schieben und die Klemmschraube einzufügen. Danach anschließend wird die an der Lichtbogenleitschiene angefügte bzw. angeformte Klemmenabstützung eingefügt, wodurch der erste Klemmenkasten zu dem geschlossenen Rahmen ergänzt wird. Wenn der erste Klemmenkasten mit der Lichtbogenleitschiene bspw. durch Schweißen fest verbunden ist, ist die Anschlußklemme fertiggestellt und in der Arbeits- und Wirkungsweise genau so zu verwenden wie die Anschlußklemmen gemäß den oben genannten Druckschriften.The fact that the first terminal box is no longer a closed box frame but U-shaped and open to the inside of the switch, and that the U-shaped part is only added to the entire box frame or terminal frame by the web section of the arc guide rail, so that an additional support element is provided with which the first terminal box is then supplemented to form a practically closed frame, both terminal boxes can be manufactured independently of one another and combined with one another; it is then only necessary to push the second terminal box over the lower crosspiece of the first terminal box and the Insert clamping screw. Then the terminal support attached or molded onto the arc guide rail is inserted, whereby the first terminal box is supplemented to form the closed frame. If the first terminal box is firmly connected to the arc guide rail, for example by welding, the connection terminal is completed and the method of operation and operation can be used in exactly the same way as the connection terminals according to the above-mentioned documents.

Anhand der Zeichnung, in der ein .Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere Vorteile, Ausgestaltungen und weitere Verbesserungen näher erläutert und beschrieben werden.The invention and further advantages, refinements and further improvements will be explained and described in more detail with reference to the drawing, in which an exemplary embodiment of the invention is shown.

Auf der in der Zeichnung gemäß Fig. 1 rechten Seite befindet sich ein Thermobimetall 15, das über ein Zwischenglied 16 auf das Schaltschloß 12 zu dessen Entklinkung einwirkt. Auf der linken Seite von Schaltschloß 12 und elektromagnetischem Auslöser 13 befindet sich ein beweglicher bzw. drehbarer Kontakthebel 17, der bei Punkt 18 drehbar aufgelagert ist. An dem bewegbaren Kontakthebel 17 ist ein bewegliches Kontaktstück 19 angeformt, das mit einem Festkontaktstück im Bereich 20 zusammenwirkt. Der elektromagnetische Auslöser 13 besitzt einen Schlaganker 21, mit dem der bewegliche Kontakthebel bei Auftreten eines Kurzschlusses aufgeschlagen wird. Er besitzt ferner einen nach rechts hin aus dem elektromagnetischen Auslöser 13 herausragenden Fortsatz 22, mit dem er über ein Hebelgestänge 23 auf das Schaltschloß 12 einwirkt. Über einen weiteren Zwischenhebel 24 wirkt das Schaltschloß 12 auf den beweglichen Kontakthebel 17 zu dessen Öffnung ein.1 shows a commercially available circuit breaker 10. In the housing 11 of the circuit breaker 10 there is a switch lock 12, including an electromagnetic release 13 and underneath this an arc extinguishing chamber 14 with arc extinguishing plates. On the In the drawing according to FIG. 1, on the right side, there is a bimetallic metal 15, which acts on the switching lock 12 via an intermediate member 16 to unlatch it. On the left side of the switching mechanism 12 and the electromagnetic trigger 13 there is a movable or rotatable contact lever 17 which is rotatably supported at point 18. A movable contact piece 19, which interacts with a fixed contact piece in the region 20, is formed on the movable contact lever 17. The electromagnetic trigger 13 has an impact armature 21, with which the movable contact lever is opened when a short circuit occurs. It also has an extension 22 protruding to the right from the electromagnetic trigger 13, with which it acts on the switching mechanism 12 via a lever linkage 23. The switching lock 12 acts on the movable contact lever 17 to open it via a further intermediate lever 24.

Das Lichtbogenlöschblechpaket 14 ist nach unten hin von einer Lichtbogenleitschiene 25 begrenzt, die im wesentlichen L-förmig gebogen ist und an deren anderem Schenkel eine Anschlußklemme 26 befestigt ist. Diese Anschlußklemme 26 entspricht der Anordnung gemäß Fig. 5, so daß die Ausgestaltung der Anschlußklemme 26 anhand der Fig. 5 dargestellt werden kann.The arc quenching plate packet 14 is bounded at the bottom by an arc guide rail 25, which is bent essentially in an L-shape and to whose other leg a connecting terminal 26 is fastened. This connecting terminal 26 corresponds to the arrangement according to FIG. 5, so that the configuration of the connecting terminal 26 can be illustrated with reference to FIG. 5.

Die Anschlußklemme 26 besitzt einen ersten Klemmenkasten 27, der einen U-förmig gebogenen ersten Abschnitt 28 aufweist, dessen einer Schenkel den oberen Quersteg 29 und dessen anderer Schenkel den unteren Quersteg 31 bildet und bei dem sich dazwischen der senkrecht dazu verlaufende äußere Längssteg 30 befindet. Der untere Quersteg 31 ist wie aus Fig. 2 ersichtlich ist, gegenüber dem Längssteg 30 schmaler ausgebildet und besitzt an seinen beiden Längskanten Vorsprünge 32, deren Funktion weiter unten näher erläutert ist.The connecting terminal 26 has a first terminal box 27 which has a U-shaped first section 28, one leg of which forms the upper crossbar 29 and the other leg of which forms the lower crossbar 31 and in between which there is the perpendicular longitudinal web 30. The lower crosspiece 31 is opposite, as can be seen from FIG. 2 the longitudinal web 30 is formed narrower and has projections 32 on its two longitudinal edges, the function of which is explained in more detail below.

An dem freien Schenkel des oberen Quersteges 29 ist eine senkrecht dazu angeformte Fahne 33 angeformt, die in der Ebene des oberen Quersteges 29 gesehen L-förmig ausgebildet ist; der unmittelbar an dem oberen Quersteg angeformte Schenkel 34 geht über in einen quer dazu verlaufenden Schenkel 35, der zur Befestigung von Anschlußlitzen bzw. Anschlußleitungen zu weiteren Komponenten des Leitungsschutzschalters dient. Im oberen Quersteg 29 befindet sich eine Bohrung 3b.On the free leg of the upper crosspiece 29, a flag 33 is formed which is formed perpendicularly thereto and which, seen in the plane of the upper crosspiece 29, is L-shaped; the leg 34 formed directly on the upper crossbar merges into a leg 35 extending transversely thereto, which is used to fasten connecting leads or connecting lines to further components of the circuit breaker. A bore 3b is located in the upper crosspiece 29.

Der zweite Klemmenkasten 37 (siehe Fig. 3) bildet einen geschlossenen Rahmen mit einem U-förmigen Bereich 38; die beiden Schenkelenden sind gegeneinander abgewinkelt und überlappen sich; sie bilden dabei den oberen Quersteg 39 des zweiten Klemmenkastens 37. Die Schenkel des U-förmigen Bereiches besitzen Schlitze 40 bzw. 41; in diese Schlitze 40 bzw. 41 greifen die Vorsprünge 32 ein, um den zweiten Klemmenkasten 37 gegenüber dem ersten Klemmenkasten verdrehsicher zu führen. Der obere Quersteg 39 besitzt eine Gewindebohrung 42.The second terminal box 37 (see FIG. 3) forms a closed frame with a U-shaped area 38; the two ends of the legs are angled towards each other and overlap; they form the upper crosspiece 39 of the second terminal box 37. The legs of the U-shaped area have slots 40 and 41; The projections 32 engage in these slots 40 and 41 in order to guide the second terminal box 37 against rotation relative to the first terminal box. The upper crossbar 39 has a threaded bore 42.

Die Figur 4 zeigt die Lichtbogenleitschiene 25. Sie dient mit dem in der Figur 4 unten gezeichneten Bereich 43 als untere Begrenzung des Lichtbogenlöschblechpaketes 14 (siehe Figur 1) und ist daher an dieser Stelle parallel zu dem Boden des Gehäuses 11 des Leistungsschutzschalters 10 in das Gehäuse 11 eingelegt. Der senkrecht hierzu verlaufende Bereich 44 besitzt eine U-förmige Umbiegung 45, wobei die Länge L des Schenkels der Umbiegung 45 der Höhe H bzw. dem Abstand H des oberen vom unteren Quersteges 29/31 des ersten Klemmenkastens entspricht. Man erkennt in der Figur 5, daß im montierten Zustand der Schenkel der Umbiegung 45 genau zwischen den oberen Quersteg 29 und den unteren Quersteg 31 hineinpaßt. Damit ergänzt die Umbiegung 45 den U-förmigen Abschnitt '20 zum vollständigen ersten Klemmenkasten bzw. Kastenrahmen , wobei die-Umbiegung 45 den inneren Längssteg des ersten Klemmenkastens bildet. Die Schenkel, also die oberen und unteren Querstege 29, 31, können sich beim Unterklemmen einer Leitung oder dergleichen auf der Umbiegung 45 abstützen.FIG. 4 shows the arc guide rail 25. It serves, with the area 43 drawn at the bottom in FIG. 4, as the lower limit of the arc-quenching plate package 14 (see FIG. 1) and is therefore at this point parallel to the bottom of the housing 11 of the circuit breaker 10 in the housing 11 inserted. The area 44 running perpendicularly to this has a U-shaped bend 45, the length L of the leg of the bend 45 of the height H or the distance H of the upper from corresponds to the lower cross piece 29/31 of the first terminal box. It can be seen in FIG. 5 that in the assembled state the leg of the bend 45 fits exactly between the upper crosspiece 29 and the lower crosspiece 31. The bend 45 thus complements the U-shaped section '20 to form the complete first terminal box or box frame, the bend 45 forming the inner longitudinal web of the first terminal box. The legs, that is to say the upper and lower transverse webs 29, 31, can be supported on the bend 45 when a line or the like is clamped in.

Die Lichtbogenleitschiene 25 besitzt eine über die Außenfläche des Steges 4b der U-förmigen Umbiegung 45 hinausgehende Verlängerung 47, die gegen die Ausformung 33 bzw. gegen den Schenkel 34 der Ausformung angeschlagen wird (siehe Fig. 5), wobei beide mittels einer Schweißverbindung 48 fest miteinander verbunden sind.The arc guide rail 25 has an extension 47 which extends beyond the outer surface of the web 4b of the U-shaped bend 45 and which is struck against the formation 33 or against the leg 34 of the formation (see FIG. 5), both of which are fixed by means of a welded connection 48 are interconnected.

Die Fertigung der Anschlußklemme verläuft dann wie folgt:The connection terminal is then manufactured as follows:

Zunächst wird der erste Kasten bzw. Klemmenrahmen 27 gestanzt, was insoweit keine Schwierigkeit bereitet. Sodann wird der zweite Klemmenkasten 37 mit dem ersten Klemmenkasten 27 zusammengesetzt und zwar dergestalt, daß der Schenkel bzw. der untere Quersteg 31 in die Öffnung des zweiten Klemmenkastens 37 eingreift. Dabei ist dafür zu sorgen, daß die Vorsprünge 32 in die Schlitze 40 bzw. 41 eingreifen. Sodann wird die vorgeformte Lichtbogenleitschiene 25 mit der Abbiegung bzw. Umbiegung 45 an den ersten Klemmenkasten'27 angesetzt, in dem der Schenkel der Umbiegung 45 zwischen dem unteren und oberen Quersteg 29 bzw. 31 des ersten Klemmenkastens eingefügt wird. Sodann wird eine feste Verbindung zwisehen dem Steg 33 und der Verlängerung 47 durch Verschweißen bei 48 hergestellt. Demgemäß bildet im fertigmontierten und zusammengesetzten Zustand die Lichtbogenleitschiene mit der Anschlußklemme eine Einheit bzw. ergänzt die Lichtbogenleitschiene die Anschlußklemme zu einer fertigen Kastenklemme. Schlußendlich wird eine Klemmschraube 49 in die Gewindebohrung 42 eingeschraubt, wobei die Klemmschraube 49 die Bohrung 36 im oberen Quersteg durchgreift. Die Umbiegung 45 dient jetzt zur Abstützung des oberen gegenüber dem unteren Quersteg 29 bzw. 31 beim Festklemmen von Anschlußleitern entweder zwischen dem unteren Quersteg und der zweiten Kastenklemme (Leiteranschluß I) oder zwischen dem Klemmenschraubenkopf und dem oberen Quersteg (Leiteranschluß II).First, the first box or clamp frame 27 is punched, which is not a problem in this respect. Then the second terminal box 37 is assembled with the first terminal box 27 in such a way that the leg or the lower transverse web 31 engages in the opening of the second terminal box 37. It should be ensured that the projections 32 engage in the slots 40 and 41, respectively. Then the preformed arc guide rail 25 with the bend or bend 45 is attached to the first terminal box 27, in which the leg of the bend 45 is inserted between the lower and upper crossbar 29 and 31 of the first terminal box. Then a firm connection between see the web 33 and the extension 47 made by welding at 48. Accordingly, in the fully assembled and assembled state, the arc guide rail forms a unit with the connection terminal or supplements the arc guide rail to form a finished box terminal. Finally, a clamping screw 49 is screwed into the threaded bore 42, the clamping screw 49 passing through the bore 36 in the upper crosspiece. The bend 45 is now used to support the upper compared to the lower crossbar 29 or 31 when clamping connection conductors either between the lower crossbar and the second box terminal (conductor connection I) or between the terminal screw head and the upper crossbar (conductor connection II).
