Abstract

The invention relates to connecting bars (1; 4; 7; 13; 31; 43) for electrical appliances and devices, for different nominal currents. Said connecting bars are configured in such a way that they are hollow. The connecting bars can have one or more cavities (2; 5; 8; 18-20; 24-36; 32). According to the invention, the connecting bars (1; 4; 7; 13; 31; 43) have the same outer cross-section for all current intensities but have different wall thicknesses for different current intensities, and therefore differently sized cavities (2; 5; 8; 18-20; 24-26; 32). The connecting bar feed-through openings into the respective switched housings of a type series can therefore all be configured identically, according to the dimensions for the connecting bars with the maximum current intensity.

Description

Die Erfindung betrifft Anschlussschienen aus profiliertem Halbzeug für elektrische Geräte und Apparate zur Verbindung elektrischer Komponenten der elektrischer Geräte und Apparate mit einem äußeren Stromkreis, wobei die für unterschiedlich hohe Nennströme den gleichen äußeren Querschnitt aufweisen und in einer Wand der Geräte- oder Apparate in einer dem genannten Querschnitt angepassten Fensteröffnung aufgenommen und an der Wand durch Befestigungsmittel fixiert sind.The invention relates to connecting rails made of profiled Semi-finished products for electrical devices and apparatus for connection electrical components of electrical devices and apparatus with an external circuit, which for different high rated currents have the same outer cross-section and in a wall of the equipment in one of the named Cross-section adapted window opening added and are fixed to the wall by fasteners.

An dem aus dem Gehäuse nach außen hindurchgeführten Teil einer Anschlussschiene dieser Art, wie sie in der FR 2 484 135 A1 beschrieben ist, kann auf diese Weise eine anlagenseitige Zuleitungsschiene angeschlossen werden. Die Anschlussschiene ist dabei in der Regel in der isolierenden Wand eines Gerätes oder Apparates fest angeordnet, was beispielsweise durch Klemmschrauben erfolgen kann.On the part of a led out of the housing Connection rail of this type, as described in FR 2 484 135 A1 is described, can in this way a plant Supply rail can be connected. The connecting rail is usually in the insulating wall of a device or fixedly arranged, for example, by Clamping screws can be done.

Nach der erwähnten FR 2 484 135 A1 werden die Anschlussschienen an die unterschiedlichen Nennströme dadurch angepasst, dass der einheitliche Querschnitt aus mehreren Teilstücken zusammengesetzt wird, die aus Kupfer bzw. Aluminium bestehen. Für den höchsten vorgesehenen Nennstrom werden nur Teilstücke aus Kupfer benutzt, während für den niedrigsten vorgesehenen Nennstrom nur Teilstücke aus Aluminium verwendet werden. Für dazwischen liegende Nennströme weisen die Anschlussschienen Kombinationen von Teilstücken aus beiden genannten Materialien auf, z. B. ein Teilstück aus Kupfer, drei Teilstücke aus Aluminium. According to the FR 2 484 135 A1 mentioned, the connecting rails adapted to the different nominal currents, that the uniform cross-section consists of several sections is composed, which consist of copper or aluminum. Only sections are used for the highest intended nominal current made of copper while intended for the lowest Nominal current only sections made of aluminum can be used. For The connecting bars have nominal currents in between Combinations of sections from the two materials mentioned on, e.g. B. a section of copper, three sections Aluminum.

Es gibt auch den Vorschlag (ältere Patentanmeldung mit dem Aktenzeichen DE 199 30 813.6, veröffentlicht als DE 199 30 813 A1), Anschlussschienen aus Abschnitten eines profilierten Halbzeuges herzustellen, das Stege oder Rippen aufweist, die einen vom Nennstrom abhängenden Querschnitt zu einem für alle Nennströme gleichen Abstandsmaß ergänzen. Dies macht die Benutzung unterschiedlicher Materialien und mehrerer Teilstücke entbehrlich.There is also the proposal (older patent application with the Case number DE 199 30 813.6, published as DE 199 30 813 A1), connecting rails made from sections of a profiled To produce semi-finished products that have webs or ribs, a cross section depending on the nominal current to one add the same distance dimension for all nominal currents. This makes use of different materials and several Parts unnecessary.

Anschlussschienen der vorstehend genannten Art können zugleich ein durch die DE 196 43 607 A1 bekannt gewordenes Merkmal aufweisen, nämlich einen weiteren Vorsprung (Steg, Rippe), der als axiale Positionierung und Abstützung der Anschlussschiene an der Wand des Gehäuses des Gerätes oder Apparates dient. Weitere Befestigungsmittel werden dann entweder gar nicht oder nur in einer vereinfachten Form benötigt. Werden Schrauben benutzt, so können diese in ein Muttergewinde eingreifen, das in bekannter Weise durch eine im Isolierstoff der Wand befindliche metallische Einlegmutter oder Einpressmutter gebildet ist (DE 35 39 673 A1).Connection rails of the type mentioned above can at the same time a known from DE 196 43 607 A1 Feature, namely a further projection (web, Rib), which serves as the axial positioning and support of the connecting rail on the wall of the housing of the device or apparatus serves. Additional fasteners are then either not at all or only needed in a simplified form. If screws are used, they can be screwed into a nut thread intervene in a known manner by means of an insulating material metallic insert nut or press nut on the wall is formed (DE 35 39 673 A1).

Aus den vorstehenden Darlegungen ergibt sich, dass Stromtragfähigkeit, Wärmeabfuhr, Bereitstellung einer Fläche für Anschlüsse von Zuleitungsschienen sowie die Aufnahme und Übertragung statischer und dynamischer Kräfte zu den wesentlichen Aufgaben der Anschlussschienen gehören. Darüber hinaus soll es möglich sein, Anschlussschienen für unterschiedliche Stromstärken in Wänden mit einheitlichen Durchführungsöffnungen unterzubringen.It follows from the above explanations that current carrying capacity, Heat dissipation, provision of an area for connections of supply rails as well as the recording and transmission static and dynamic forces to the essential Tasks of the connection rails belong. Beyond that it may be possible to use connecting rails for different Current strengths in walls with uniform through openings accommodate.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, Anschlussschienen mit den genannten Eigenschaften zu schaffen, die preiswert herstellbar sind.The object of the present invention is therefore to To create connecting rails with the properties mentioned, that are inexpensive to manufacture.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass die Anschlussschienen bei gleichem äußerem Querschnitt hohl ausgebildet sind und die verbleibende Wandstärke dem jeweiligen Nennstrom angepasst ist.This object is achieved according to the invention in that the connecting rails are hollow with the same outer cross-section are formed and the remaining wall thickness the respective Rated current is adjusted.

Eine stromführende hohle Anordnung ist bereits in der US 3,597,713 beschrieben, die ein Gerät als Ersatz für eine Hochspannungs-Schmelzsicherung zeigt, in dem eine Kombination eines Vakuumschalters mit einem Schaltgriff, der, ähnlich wie ein Hoch- oder Mittelspannungstrennschalter eine Öse zur Betätigung aufweist, dargestellt ist. In einem hohlen Anschlußstück des Gerätes ist eine elektronische Schaltung eingebaut. Damit ist zwar ein stromführendes hohles Teil an einem elektrischen Schaltgerät bekannt geworden, aber dieses dient lediglich der Unterbringung einer anderen Komponente des Gerätes, nämlich der genannten elektronischen Schaltung und nicht der Regulierung der Stromtragfähigkeit des Bauteils.A current-carrying hollow arrangement is already in the US 3,597,713 described a device as a replacement for one High-voltage fuse shows in which a combination a vacuum switch with a control handle that, similar to a high or medium voltage isolating switch an eyelet for actuation has is shown. In a hollow connector an electronic circuit is built into the device. This is indeed a current-carrying hollow part on an electrical Switchgear has become known, but this only serves housing another component of the device, namely the electronic circuit mentioned and not the regulation of the current carrying capacity of the component.

Ein in der US 3 953 695 beschriebener Schaltapparat besitzt gleichfalls hohle Anschlussmittel. Durch den Hohlraum wird ein Kühlmittel geleitet, da es sich um ein Hochstromschaltgerät handelt und die Abmessungen der Anschlussmittel beschränkt werden sollen. Im Gegensatz zur Erfindung wird daher nicht von einem äußeren Querschnitt ausgegangen, der einem Höchstwert des Stromes entspricht, wobei der Hohlraum von dem jeweils vorgesehenen Nennstrom abhängt.A switching device described in US 3,953,695 has likewise hollow connection means. Through the cavity a coolant passed because it is a high current switching device acts and limits the dimensions of the connection means should be. In contrast to the invention is therefore not assume an outer cross section that one Corresponds to the maximum value of the current, the cavity of which depends on the intended nominal current.

Bei den Anschlussschienen nach der Erfindung wird im Unterschied hierzu die Stromtragfähigkeit mittels der Wandstärke der Hohlschiene reguliert, die den leitenden, stromtragenden Querschnitt bildet. Daraus ergibt sich, dass bei niedrigeren Stromstärken durch geringe Wandstärken ein größerer, beziehungsweise bei höheren Stromstärken durch dickere Wandstärken ein kleinerer innerer Hohlraum vorhanden ist, was bis hin zu einer massiven Ausgestaltung ohne Hohlraum, bei der höchsten Bemessungsstromstärke, führen kann. Auf die für diese höchste Bemessungsstromstärke erforderlichen äußeren Abmessungen sind dann die Durchführungsöffnungen in den jeweiligen Gehäusen der Geräte oder Apparate ausgelegt.A distinction is made in the connection rails according to the invention the current carrying capacity by means of the wall thickness the hollow rail regulates the conductive, current carrying Cross section forms. It follows that at lower Current strengths due to small wall thicknesses a larger one, respectively at higher currents through thicker walls a smaller internal cavity is present, which is down to a massive design with no void, at the highest Rated current. To the highest for this Rated current are the required external dimensions then the lead-through openings in the respective housings of the devices or apparatus.

Es kann zweckmäßig sein, die Anschlussschienen mit nur einem Hohlraum zu versehen. Verschiedene Gesichtspunkte, insbesondere die Größe des äußeren Gesamtquerschnittes, können jedoch dafür sprechen, mehrere Hohlräume vorzusehen.It may be appropriate to use only one connector Cavity. Different points of view, in particular the size of the overall outer cross section, however speak for providing several cavities.

Bei Anschlussschienen können Bohrungen erforderlich sein, die mit einem oder ohne ein Gewinde ausgebildet sein können, beispielsweise zu Befestigungszwecken am Gehäuse oder gegen eine axiale Verschiebung. Diese Bohrungen können in einer gemeinsamen Achse angeordnet sein oder auch gegeneinander versetzt. Um eine Deformierung der hohlen Anschlussschienen durch die Klemmkraft der durch diese Bohrungen hindurchgeführten oder in das Gewinde dieser Bohrungen eingeschraubten Schrauben zu vermeiden, können zwischen den Hohlräumen der Anschlussschienen geeignete Stege zur Erhöhung der Festigkeit vorgesehen werden. Das bedeutet bezüglich der Herstellung des Profilmaterials möglicherweise einen Mehraufwand, hat aber keinen Einfluß auf die Stromtragfähigkeit.Bores may be required for connecting rails can be formed with or without a thread, for example for fastening purposes to the housing or against one axial displacement. These holes can be shared Axis can be arranged or offset from each other. To prevent the hollow connecting rails from deforming Clamping force of the passed through these holes or screws screwed into the thread of these holes can avoid between the cavities of the connecting rails suitable webs are provided to increase the strength become. This means regarding the production of the profile material possibly an additional effort, but has none Influence on the current carrying capacity.

Zur Vermeidung dieses eventuellen Mehraufwandes können im Hohlraum der Anschlussschiene auch quer zur Längsrichtung der Anschlussschiene verlaufende Führungsnuten für bei Bedarf einzuschiebende Stützstege vorgesehen werden. Die in diese Führungsnuten einzuschiebenden Stützstege können aus dem gleichen Material bestehen, wie die Anschlussschiene, können aber auch aus einem unterschiedlichen Material bestehen.To avoid this possible additional effort can in Cavity of the connecting rail also transverse to the longitudinal direction of the Connection rails running guide grooves for if necessary support webs to be inserted are provided. The one in this Guide bars to be inserted into the support webs can be removed from the made of the same material as the connecting rail but also consist of a different material.

Diese eingeschobenen Stützstege dienen dem gleichen Zweck, wie die angeformten, nämlich der Stabilisierung der Anschlussschiene gegen eine Deformierung der hohlen Anschlussschiene durch die Klemmkraft oder Belastung von durch die Bohrungen hindurchgeführten Schraubenbolzen oder in das Gewinde dieser Bohrungen eingeschraubten Schrauben.These inserted support bars serve the same purpose, like the molded one, namely the stabilization of the connecting rail against deformation of the hollow connecting rail by the clamping force or load by the Bolts passed through holes or into the thread screws screwed into these holes.

Da diese eingeschobenen Stützstege keinen Einfluß auf die Stromtragfähigkeit ausüben, können für die Auswahl des Materials andere Gesichtspunkte, zum Beispiel die Festigkeit, als Bewertungsparameter in Betracht gezogen werden.Since these inserted support bars have no influence on the Current carrying capacity can be used for the selection of the material other considerations, for example strength, than Assessment parameters can be considered.

Die vorgenannten, mit oder ohne ein Gewinde ausgebildeten Bohrungen können im Bereich von Hohlräumen angeordnet sein, was insbesondere dann zweckmäßig ist, wenn Durchgangsbolzen hindurchgeführt werden, wobei sie dann eine gemeinsame Achse aufweisen müssen und kein Gewinde benötigen.The aforesaid, with or without a thread Bores can be arranged in the area of cavities, which is particularly useful if through bolts are passed through, then they have a common axis must have and need no thread.

Bei einer Ausbildung der Bohrungen mit einem Gewinde kann es vorteilhaft sein, sie so anzuordnen, dass sie sich in einem Steg befinden. Dadurch sind größere Gewindelängen möglich, was eine höhere Belastbarkeit der Schraubverbindung ermöglicht.If the holes are formed with a thread, it can be advantageous to arrange them so that they are in one Web. This allows longer thread lengths which enables a higher load capacity of the screw connection.

Zur Vermeidung von Befestigungsbohrungen können die Anschlussschienen auch mit an sich bekannten Anschlägen zur axialen Fixierung versehen sein. Sie werden dann durch geeignete, an sich bekannte Befestigungselemente, zum Beispiel Klemmschrauben, in axialer Richtung fixiert. Gleichzeitig oder zusätzlich können derartige Anschläge axiale Kräfte aufnehmen und diese auf das Gehäuse übertragen.The connecting rails can be used to avoid mounting holes also with known stops for be axially fixed. You will then be fasteners known per se, for example Clamping screws, fixed in the axial direction. simultaneously or in addition, such stops can absorb axial forces and transfer it to the case.

Bei allen vorstehend beschriebenen Anschlussschienen kann der Hohlraum bzw. können die Hohlräume quer zur Längserstreckung der Anschlussschiene angeordnet und beidseitig offen sein. In dieser Ausführung ist als Ausgangsmaterial vorteilhaft ein Strangpressprofil herstellbar, aus dem einzelne Anschlussschienen einer jeweils benötigten Breite abgetrennt werden können.With all connection rails described above, the Cavity or the cavities can be transverse to the longitudinal extent the connecting rail and be open on both sides. In this version is advantageous as a starting material Extruded profile can be produced from the individual connecting rails of a width required in each case can.

In dieser Ausführungsform weist sie nur einen einzigen Hohlraum 2 auf, der sich im wesentlichen über ihre gesamte Abmessung erstreckt. Diese Anschlussschiene 1 weist eine dünnere, dem niedrigen Betriebsstrom angepaßte, Wand 3 auf. Da die Außenabmessungen, also der äußere Querschnitt der Anschlussschiene 1 eine konstante Größe darstellen soll, ist der Hohlraum 2 wegen der geringen Wandstärke verhältnismäßig groß.FIG. 1 shows a first embodiment of a connecting rail 1 for electrical devices and apparatus for a small Amperage. In this embodiment, it has only one single cavity 2, which is essentially about their entire dimension. This connecting rail 1 has a thinner wall 3 adapted to the low operating current on.

Die Vorteile der erfinderischen Lösung bestehen darin, dass innerhalb einer Baugröße einheitliche äußere Abmessungen der Anschlussschienen erreicht werden, wodurch Distanzstücke und dergleichen entfallen. Innerhalb einer Baugröße können einheitliche Einführungsöffnungen und somit einheitliche Gehäuseabmessungen verwendet werden, was eine starke Reduzierung der Variantenvielfalt und eine Kostenreduzierung zur Folge hat. Die Bohrungen der Hohlprofile können gestanzt werden, was kostengünstiger und sauberer als Bohren ist. Die Verbindungstechnik vereinfacht sich auf eine Variante pro Baugröße, wodurch die Fertigung vereinfacht wird. Durch die stark vergrößerte Oberfläche von Hohlprofilen, die seitlich offen sind, erfolgt eine bessere Wärmeabfuhr.The advantages of the inventive solution are that uniform outer dimensions of the Connection rails can be reached, making spacers and the like does not apply. Uniform can be within one size Entry openings and thus uniform housing dimensions be used, which is a strong reduction the variety of variants and a cost reduction Has. The holes in the hollow profiles can be punched which is cheaper and cleaner than drilling. The connection technology simplified to one variant per size, which simplifies production. Due to the greatly enlarged Surface of hollow profiles that open laterally are better heat dissipation.
