Description

Die vorliegende Erfindung bezieht sich auf eine Halterungsvorrichtung gemäss dem Oberbegriff des Anspruchs 1 und auf eine Verwendung dieser Halterungsvorrichtung.The present invention relates to a mounting device according to the preamble of claim 1 and to a use of this mounting device.

In der US-PS 2,640,092 ist ein Widerstandsdraht mäanderartig geführt, wobei in den zentralen Teil die Teilleiter des Widerstandsdrahtes mit einem oder mehreren aus- einem elektrisch isolierenden Material bestehenden Distanzstücken gehalten werden. Ein Distanzstück ist als eine rechteckige Platte ausgestaltet, die mit Bohrungen zum Durchschieben des Widerstandsdrahtes versehen ist. Sowohl die Konstruktion als auch die Montage ist kompliziert. Durch das Distanzstück muss man den Widerstandsdraht einzeln einschieben und es sind auch elektrisch leitende Platten notwendig, um die Enden der Teilleiter zu verbinden.In US Pat. No. 2,640,092, a resistance wire is guided in a meandering manner, the partial conductors of the resistance wire being held in the central part with one or more spacers consisting of an electrically insulating material. A spacer is designed as a rectangular plate, which is provided with holes for pushing the resistance wire through. Both the construction and the assembly are complicated. The resistance wire has to be inserted individually through the spacer and electrically conductive plates are also necessary to connect the ends of the partial conductors.

Der Erfindung liegt insbesondere die Aufgabe zugrunde, die Nachteile des Bekannten zu beseitigen und eine Halterung für eine mäanderartige Wicklung zu schaffen, die mit einfachen Mitteln eine Distanzierung der Teilleiter der Wicklung ausreichend sichert und die Montage der Halterungsvorrichtung mit der Wicklung erleichtert.The invention has for its object in particular to eliminate the disadvantages of the known and to provide a holder for a meandering winding, which sufficiently secures a spacing of the partial conductors of the winding with simple means and facilitates the mounting of the mounting device with the winding.

Die vorgenannte Aufgabe wird durch die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, gelöst.The above object is achieved by the invention as characterized in the claims.

Der Vorteil des Anspruchs 1 ist darin zu sehen, dass die mäanderförmige Wicklung vorgeformt werden kann und die Distanzstücke werden in Längsrichtung der Wicklung von beiden Seiten eingeschoben. Die Weiterbildung gemäss dem Anspruch 2 stabilisiert die Lage der Endteile der Wicklung. Die Lösung gemäss dem Anspruch 3 ist insbesondere für längere Abmessungen oder für eine weniger formstabile Wicklung geeignet. Der Vorteil des Anspruchs 4 liegt in der raumsparenden Konstruktion. Die Variante nach Anspruch 5 ist ebenfalls raumsparend und ist für lange Wicklungen geeignet. Sie ermöglicht die Anordnung der Wicklung in einem zylindrischen Gehäuse. Der Vorteil der Ausführungsform gemäss Anspruch 6 besteht darin, dass die Wicklung die Distanzstücke nur in kleinen Bereichen berührt, wobei die Distanzstücke aus mechanischen Gründen ausreichend dick sein können, Die Weiterbildung nach Anspruch 7 ermöglicht, alle Distanzstücke auf einem stabförmigen Träger zu befestigen, so dass die Distanzstücke mit der Wicklung auch ohne ein Gehäuse schon ein formstabiles Ganzes bilden. Der Anspruch 8 zeigt eine vorteilhafte Verwendung der erfindungsgemässen Halterungsvorrichtung, wobei in diesem Fall der Widerstand in einer Kühlflüssigkeit, vorzugsweise im entionisierten Wasser, gekühlt wird.The advantage of claim 1 is the fact that the meandering winding can be preformed and the spacers are inserted in the longitudinal direction of the winding from both sides. The development according to claim 2 stabilizes the position of the end parts of the winding. The solution according to claim 3 is particularly suitable for longer dimensions or for a less dimensionally stable winding. The advantage of claim 4 lies in the space-saving construction. The variant according to claim 5 is also space-saving and is suitable for long windings. It enables the winding to be arranged in a cylindrical housing. The advantage of the embodiment according to claim 6 is that the winding only touches the spacers in small areas, whereby the spacers can be sufficiently thick for mechanical reasons. The development according to claim 7 enables all spacers to be fastened on a rod-shaped support, so that the spacers with the winding form a dimensionally stable whole even without a housing. Claim 8 shows an advantageous use of the mounting device according to the invention, in which case the resistor is cooled in a cooling liquid, preferably in deionized water.

Die Erfindung wird im folgenden anhand schematischer Zeichnungen näher erläutert:

The invention is explained in more detail below with the aid of schematic drawings:
  • 1 is a partial longitudinal section through two spacers according to the invention with a meandering winding extending in one plane,
  • 2 is a view of the upper spacer from FIG. 1,
  • 3 is a view of the lower spacer from FIG. 1,
  • 4 shows a variant in which four spacers are provided,
  • 5 and 6, for example, embodiments of the spacers, which are intended for a winding arranged in three floors,
  • 7 shows another embodiment according to the invention for a spiral mounting of the meandering winding,
  • Fig. 8 shows the section VIII-VIII of Fig. 7 and
  • 8 and 9 also parts of the winding are drawn.

In Fig. 1 ist eine mäanderförmige Wicklung 1 aus Runddraht dargestellt. Die Wicklung 1 ist mit vorgeformten gebogenen Teilen 1' versehen, so dass sie antiparallele Abschnitte bildet und beim Stromdurchfluss als Ganzes nur eine niedrige Induktivität aufweist. Ein Distanzstück 2 wurde von oben eingeschoben, ein anderes Distanzstück 3 von unten. Das Distanzstück ist mit einem Loch 4 und mit mehreren länglichen Löchern 5 versehen. Im Distanzstück 3 sind nur die länglichen Löcher 5 ausgeführt. Beim Vergleich der beiden Distanzstücke 2, 3 ist die gegenseitige Verschiebung der länglichen Löcher 5 sichtbar. Diese Verschiebung ermöglicht, dass jeder der parallelen Abschnitte der Wicklung l mit dem Distanzstück 2 von einer Seite und mit dem anderen Distanzstück 3 von der anderen Seite abgestützt ist. Im mittleren Bereich der Wicklung 1 zwischen den Distanzstücken 2 und 3 ist also die Wicklung 1 getragen, in den Endbereich B ist die Wicklung 1 ohne Abstützung.In Fig. 1 a meandering winding 1 made of round wire is shown. The winding 1 is provided with preformed curved parts 1 ', so that it forms anti-parallel sections and has only a low inductance as a whole when the current flows through. A spacer 2 was inserted from above, another spacer 3 from below. The spacer is provided with a hole 4 and with several elongated holes 5. Only the elongated holes 5 are made in the spacer 3. When comparing the two spacers 2, 3, the mutual displacement of the elongated holes 5 is visible. This displacement enables each of the parallel sections of the winding 1 to be supported with the spacer 2 from one side and with the other spacer 3 from the other side. The winding 1 is thus carried in the central region of the winding 1 between the spacers 2 and 3, and in the end region B the winding 1 is without support.

Die Länge der Bereiche A und B ist von der mechanischen Festigkeit der konkreten Wicklung 1 abhängig, wobei vor allem das Material, der Drahtquerschnitt und die einzuhaltenden Windungsabstände in Betracht zu ziehen sind. Im rechten Teil der Fig. 1 ist die Variante gezeichnet, bei der auch das rechte Ende der Wicklung 1 durch das obere Distanzstück 2 geführt wird. Das Loch für dieses Ende ist mit 4' bezeichnet. Die Distanzstücke können verschieden gelocht werden, wie das z.B. in Fig. 1 gezeigt ist, sie können auch gleich ausgeführt werden, wobei sie gegenseitig umgekehrt eingesetzt werden.The length of the areas A and B depends on the mechanical strength of the specific winding 1, whereby before the material, the wire cross-section and the distance between the turns must be taken into account. The right part of FIG. 1 shows the variant in which the right end of the winding 1 is also guided through the upper spacer 2. The hole for this end is labeled 4 '. The spacers can be perforated differently, as is shown, for example, in FIG. 1, they can also be made the same, whereby they are used mutually in reverse.

In Fig. 2 ist eine Ansicht auf das obere Distanzstück 2 und in Fig. 3 auf das untere Distanzstück 3 gezeigt. Die mittleren Teile in den Fig. 1 bis 3 sind ausgelassen worden.FIG. 2 shows a view of the upper spacer 2 and in FIG. 3 the lower spacer 3. The middle parts in Figs. 1 to 3 have been omitted.

Gleiche Teile sind in allen Figuren mit denselben Bezugsziffern versehen.Identical parts are provided with the same reference numbers in all figures.

Fig. 4 zeigt eine Variante, die im wesentlichen derjenigen gemäss Fig. 1 entspricht, bei der jedoch aus mechanischen Gründen zwei obere Distanzstücke 2 und zwei untere Distanzstücke 3 angeordnet sind.FIG. 4 shows a variant which essentially corresponds to that according to FIG. 1, but in which, for mechanical reasons, two upper spacers 2 and two lower spacers 3 are arranged.

In den Fig. 5 und 6 sind Distanzstücke 6 und 7 veranschaulicht, die für eine dreietagige Wicklung 1 bestimmt sind.5 and 6, spacers 6 and 7 are illustrated, which are intended for a three-day winding 1.

Fig. 7 zeigt ein Distanzstück 8 für eine spiralförmige Montage der mäanderförmigen Wicklung 1. Diese Wicklung 1 ist in der Fig. 7 nicht gezeichnet. Das Distanzstück 8 ist in dieser beispielsweisen Ausgestaltung scheibenförmig ausgebildet und ist mit einer Befestigungsöffnung 10 versehen. Mittels dieser Befestigungsöffnung kann man zwei oder mehrere Distanzstücke 8 auf einem stabförmigen Träger befestigen.FIG. 7 shows a spacer 8 for a spiral mounting of the meandering winding 1. This winding 1 is not shown in FIG. 7. The spacer 8 is disc-shaped in this exemplary embodiment and is provided with a fastening opening 10. By means of this fastening opening, two or more spacers 8 can be fastened on a rod-shaped carrier.

Fig. 8 zeigt den Schnitt VIII-VIII aus Fig. 7. Wegen der Anschaulichkeit sind in diesem Schnitt auch Teile der Wicklung 1 eingezeichnet. Die länglichen Löcher 5 weisen in den mittleren Zonen je eine Verjüngung 9 auf, so dass die äusseren Querschnitte der Löcher 5 grösser sind als der innnere Querschnitt. Diese Konstruktion erleichtert die Montage, wobei die Kontaktfläche der Wicklung 1 mit dem Distanzstück 8 klein bleibt.FIG. 8 shows the section VIII-VIII from FIG. 7. Because of the clarity, parts of the wick are also in this section lung 1 shown. The elongated holes 5 each have a taper 9 in the central zones, so that the outer cross sections of the holes 5 are larger than the inner cross section. This construction facilitates assembly, the contact area of the winding 1 with the spacer 8 remaining small.

Der Schnitt IX-IX aus Fig. 7 ist in Fig. 9 veranschaulicht. Dieser Schnitt verläuft senkrecht zu dem in Fig. 8 gezeigten Schnitt VIII-VIII. Im linken Teil sind Teile der Wicklung 1 gezeigt, im rechten Teil ist anschaulich die Verjüngung 9 der länglichen Löcher 5 dargestellt.The section IX-IX from FIG. 7 is illustrated in FIG. 9. This section runs perpendicular to the section VIII-VIII shown in FIG. 8. Parts of the winding 1 are shown in the left part, the taper 9 of the elongated holes 5 is clearly shown in the right part.

Der Erfindungsgegenstand ist auf das in der Zeichnung Dargestellte selbstverständlich nicht beschränkt. Man kann auch andere Formen der Distanzstücke verwenden und die Merkmale der Ansprüche beliebig kombinieren.The subject of the invention is of course not limited to what is shown in the drawing. You can also use other forms of spacers and combine the features of the claims as desired.
