Abstract

The invention concerns a wiring component (11) with which a power switch (1) can be interconnected both with an alternating current contactor (2) as well as with a direct current contactor (3), even when the connecting strips (5, 8) of the contactors (2, 3) are placed differently with respect to the connecting strips (4) of the power switch (1). This is effected by matching the bend and the material thickness m of the two Z-shaped stamped bent parts (12) used in the wiring component (11).

VerdrahtungsbausteinWiring module
Die Erfindung bezieht sich auf einen Verdrahtungsbaustein mit Z-förmigen Stanzbiegeteilen.The invention relates to a wiring module with Z-shaped stamped and bent parts.
Verdrahtungsbausteine mit Stanzbiegeteilen sind an sich zur Verdrahtung zweier Schaltgeräte, z.B. eines Leistungsschal- ters mit einem Schütz bekannt. In der Praxis stellt sich das Problem, daß der Leistungsschalter je nach Anwendungsfall mit einem Schütz mit Wechselstromantrieb oder mit einem Schütz mit Gleichstromantrieb zu verschalten ist. Aufgrund der für die Schützausführungen unterschiedlichen Anschlußebenen, in denen die jeweiligen Anschlußschienen liegen, war bisher die Vorhaltung von zwei verschiedenen Verdrahtungεbausteinen erforderlich, die je nach Anwendungsfall zum Einsatz kamen.Wiring modules with stamped and bent parts are per se for wiring two switching devices, e.g. of a circuit breaker with a contactor. In practice, the problem arises that, depending on the application, the circuit breaker can be connected to a contactor with an AC drive or with a contactor with a DC drive. Due to the different connection levels for the contactor versions, in which the respective connection rails are located, it was previously necessary to provide two different wiring modules, which were used depending on the application.
Der Erfindung liegt die Aufgabe zugrunde, nur einen einzigen Verdrahtungsbaustein der obengenannten Art zu schaffen, mit dem die beiden genannten Anwendungsfälle abgedeckt werden, wenn die Abstände der Anschlußebenen, in denen die Anschlu߬ schienen der Schaltgeräte liegen, bekannt sind. Die Aufgabe wird erfindungsgemäß mit einem Verdrahtungsbaustein mit den Merkmalen nach Anspruch 1 gelöst.The invention has for its object to provide only a single wiring module of the type mentioned above, with which the two applications mentioned are covered if the distances between the connection levels in which the connecting rails of the switching devices are known. The object is achieved with a wiring module with the features of claim 1.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG 1 zwei Anwendungsfälle einer elektrischen Verbindung eines Leistungsschalters mit einem Schütz, FIG 2 die elektrische Verbindung in den beiden Anwendungs- fällen gemäß FIG 1 durch einen einzigen Verdrahtungs¬ baustein.1 shows two applications of an electrical connection of a circuit breaker with a contactor, FIG. 2 shows the electrical connection in the two applications according to FIG. 1 by means of a single wiring module.
In FIG 1 sind beispielhaft zwei Anwendungsfälle gezeigt, für die der erfindungsgemäße Verdrahtungsbaustein zum Einsatz kommen soll. Die in der Zeichnung oben dargestellten Schalt¬ geräte sind Leistungsschalter 1 gleicher Ausführung. Je nach Anwendungsfall ist der Leistungsschalter 1 mit einem Schütz 2 mit Wechselstromantrieb zu verdrahten, wie linksseitig abge- bildet oder mit einem Schütz 3 mit einem Gleichstromantrieb wie rechtsseitig abgebildet. Im linksseitigen Anwendungsfall liegen sich die erste Anschlußschiene 4 des Leistungsschal- ters 1 und die zweite Anschlußschiene 5 des Schützes 2 mit Wechselstromantrieb direkt gegenüber, d.h. der Abstand ai zwischen der ersten Anschlußebene des Leistungsschalters 1 und der zweiten Anschlußebene 7 des Schützes 2 beträgt Null. Im rechtsseitigen Anwendungsfall ist der Abstand a2 zwischen der ersten Anschlußebene 4 des Leistungsschalters 1 und der dritten Anschlußebene 9 für die dritte Anschlußschiene 8 des Schützes 3 mit Gleichstromantrieb verschieden von Null wie in FIG 2 im einzelnen dargestellt. Die Anschlußschienen 4,5,8 haben die Dicke d.1 shows two examples of applications for which the wiring module according to the invention is used should come. The switching devices shown in the drawing above are circuit breakers 1 of the same design. Depending on the application, the circuit breaker 1 is to be wired with a contactor 2 with an AC drive, as shown on the left, or with a contactor 3 with a DC drive as shown on the right. In the left-hand application, the first connecting bar 4 of the circuit breaker 1 and the second connecting bar 5 of the contactor 2 with AC drive are directly opposite one another, ie the distance ai between the first connection level of the circuit breaker 1 and the second connection level 7 of the contactor 2 is zero. In the right-hand application, the distance a2 between the first connection level 4 of the circuit breaker 1 and the third connection level 9 for the third connection rail 8 of the contactor 3 with DC drive is different from zero as shown in FIG. 2 in detail. The connecting rails 4,5,8 have the thickness d.
Der erfindungsgemäße Verdrahtungsbaustein 10 gemäß FIG 2 ist aus einem Kunststoffgehäuse 11 mit drei eingelegten oder ein¬ gespritzten Z-förmigen Stanzbiegeteilen 12 für die drei Phasen gefertigt. Die Biegungen und die Materialstärke m der Stanzbiegeteile 12 sind so aufeinander abgestimmt, daß durch Drehung um 180° die unterschiedlichen Anschlußebenen 6,7,9 ausgeglichen werden. Beim Schütz 2 bzw. 3 muß der Verdrah¬ tungsbaustein 10 immer hinter der jeweiligen Anschlußschiene 5 bzw. 8 liegen, da bei Wendestartern der Platz vor der An¬ schlußschiene für den Anbau eines Wende-Verdrahtungsbaustei¬ nes benötigt wird. Dieses ist bei Fahrstuhl-Rahmenklemmen und Flachanschlüssen anwendbar.The wiring module 10 of the invention shown in FIG 2 is constructed of a plastic housing 11 with three inlaid or a ¬ sprayed Z-shaped stamped and bent parts 12 made for the three phases. The bends and the material thickness m of the stamped and bent parts 12 are coordinated with one another in such a way that the different connection planes 6, 7, 9 are compensated for by rotation through 180 °. With contactor 2 or 3, the wiring module 10 must always be located behind the respective connecting rail 5 or 8, since in the case of reversing starters, the space in front of the connecting rail is required for the attachment of a reversing wiring module. This can be used for lift box clamps and flat connections.
In der nebenstehenden Tabelle sind drei Lösungsprinzipien I, II, III aufgeführt, die sich nur in der Belegung der An¬ schlußöffnungen des Leistungsschalters 1 bzw. dem Drehen des Verdrahtungsbausteines 10 unterscheiden. Diese wurden an fünf Anwendungsfällen a,b,c,d,e gespiegelt. Abhängig von den vorgegebenen Abständen al,a2 der Anschlu߬ schienendicke d und dem Lösungsprinzip ergeben sich verschie¬ dene Abmessungen und Formen für den Verdrahtungsbaustein 10 bzw. seiner Stanzbiegeteile 12. Bei mehreren Lösungen wird sinnvollerweise die technisch und wirtschaftlich günstigste ausgewählt. In the adjacent table are three principles solution I, II, III listed, the locking openings only in the assignment of the at ¬ of the circuit breaker 1 and the turning of the wiring block 10 differ. These were reflected in five use cases a, b, c, d, e. A depending on the specified distances a1, a2 of the connecting rail thickness d and the solution principle, there are various dimensions and shapes for the wiring module 10 or its stamped and bent parts 12. In the case of several solutions, the technically and economically most advantageous is selected.
