Abstract

A pole casing feed-through for the field connection of a starting device for internal combustion engines has an essentially round opening (3) in the pole casing (1) and a connecting bolt (4) which can be lodged in the opening and fixed to the casing (1). Said bolt has a first electrically conductive connection (11) inside the casing (1), a second electrically conductive connection (17) outside the casing (1), and a rotary projection (5) at its outer end. A closed profiled ring (6) made of an elastic material is mounted on the connecting bolt (4). The advantage of this feed-through is that it ensures optimal protection against the entry of moisture into the pole casing even in the case of strong vibrations and wide temperature fluctuations. The elastic profiled ring is closed around its periphery and its entire peripheral surface is in contact with the pole casing. When assembled, it is pressed against the pole casing by the connecting bolt.

Description

Polgehäusedurchführung für den Feldanschluß einer Andrehvorrichtung  Pole housing bushing for the field connection of a starter
Stand der Technik State of the art
Die Erfindung betrifft eine Polgehäusedurchführung für den Feldanschluß einer Andrehvorrichtung für Brennkraftmaschinen nach der Gattung des Anspruchs 1. The invention relates to a pole housing bushing for the field connection of a starting device for internal combustion engines according to the preamble of claim 1.
Bekannte Polgehäusedurchführungen werden dadurch hergestellt, daß in das Polgehäuse einer Andrehvorrichtung ein im wesentlichen U-förmiger Schlitz eingebracht wird und zwar in den Randbereich des Gehäuses, der sich unmittelbar an den Polgehäusedeckel anschließt. Der elektrische Anschluß der Erregerwicklung wird dadurch hergestellt, daß ein mit einem Ende der Erregerwicklung verlöteter Stab beim Zusammen bauen der Andrehvorrichtung in den Schlitz des Polgehäuses eingeführt wird. An dem freien außerhalb des Gehäuses liegenden Ende des Stabs ist üblicherweise eine Litze angelötet, die mit der Stromversorgung zu verbinden ist. Um den Stab wird ein mit einem Schlitz versehener Profilgummiring gelegt, der den Stab gegenüber dem Polgehäuse isolierend hält. Anschließend wird der Polgehäusedeckel auf das Polgehäuse der Andrehvorrichtung aufgesetzt, so daß der Stab in dem Schlitz gehalten wird. Nachteil dieser Polgehäusedurchführung ist es, daß der Profilgummiring einen Schlitz aufweist, durch den insbesondere bei großen Temperaturschwankungen und bei Vibrationen Feuchtigkeit in das Gehäuεeinnere eindringen kann, überdies ist die Dichtwirkung des Profilrings am Übergang zwischen Polgehäuse und Polgehäusedeckel nicht immer optimal, so daß auch hier Feuchtigkeit in das Gehäuse eindringen kann. Known pole housing bushings are produced by introducing an essentially U-shaped slot into the pole housing of a starter device, specifically in the edge region of the housing, which directly adjoins the pole housing cover. The electrical connection of the excitation winding is established in that a rod soldered to one end of the excitation winding during assembly build the starter is inserted into the slot of the pole housing. A strand is usually soldered to the free end of the rod outside the housing and is to be connected to the power supply. A slotted profile rubber ring is placed around the rod, which holds the rod in an isolating manner from the pole housing. The pole housing cover is then placed on the pole housing of the starter device, so that the rod is held in the slot. The disadvantage of this pole housing bushing is that the profile rubber ring has a slot through which moisture can penetrate into the interior of the housing, particularly in the case of large temperature fluctuations and vibrations, moreover the sealing effect of the profile ring at the transition between the pole housing and the pole housing cover is not always optimal, so that moisture is also present here can penetrate into the housing.
Vorteile der Erfindung Advantages of the invention
Die Polgehäusedurchführung mit den in Anspruch 1 aufgeführten Merkmalen hat demgegenüber den Vorteil, daß sie auch bei starken Vibrationen und großen Temperaturschwankungen einen optimalen Schutz gegen Feuchtigkeit gewährt. Der elastische Profilring ist rundum in sich geschlossen und liegt mit seiner gesamten Umfangsflache an dem Polgehäuse an. Nach Fertigstellung der Polgehäusedurchführung steht der Profilring unter Spannung. Dadurch wird einerseits die optimale Dichtwirkung und andererseits eine Dämpfung von Vibrationen erreicht, so daß die Durchführung auch bei starken Vibrationen und großen Temperaturschwankungen ihre Dichtwirkung nicht verliert. The pole housing bushing with the features listed in claim 1 has the advantage that it provides optimal protection against moisture even with strong vibrations and large temperature fluctuations. The elastic profile ring is completely self-contained and lies with its entire circumferential surface on the pole housing. After completion of the pole housing bushing, the profile ring is under tension. As a result, the optimal sealing effect is achieved on the one hand and damping of vibrations on the other hand, so that the implementation also at strong vibrations and large temperature fluctuations do not lose their sealing effect.
Durch die in den ünteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch genannten Polgehäusedurchführung möglich. Besonders vorteilhaft ist es, daß die Durchführung auch automatisch hergestellt werden kann. Advantageous further developments and improvements of the pole housing bushing mentioned in the main claim are possible through the measures listed in the subclaims. It is particularly advantageous that the implementation can also be made automatically.
Zeichnung drawing
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. An embodiment of the invention is shown in the drawing and is explained in more detail in the following description.
Die Figur zeigt einen Schnitt durch einen Teil des Gehäuses einer Andrehvorrichtung, nämlich durch den nahe dem Lager- bzw. Polgehäusedeckel liegenden Endbereich des Polgehäuses. The figure shows a section through part of the housing of a starter device, namely through the end region of the pole housing which is close to the bearing or pole housing cover.
Beschreibung des Ausführungsbeispieles Description of the embodiment
Die hier beschriebene Polgehäusedurchführung eignet sich grundsätzlich für alle Gehäusedurchführungen für einen elektrischen Anschluß. Beispielshaft ist in der Figur eine Polgehäusedurchführung für den FeldanschluB einer Andrehvorrichtung einer Brennkraftmaschine dargestellt. The pole housing bushing described here is basically suitable for all housing bushings for an electrical connection. The figure shows a pole housing bushing for the field connection of a starter device of an internal combustion engine.
Die Figur zeigt einen Ausschnitt aus einem Gehäuse einer Andrehvorrichtung und zwar den Bereich, des Polgehäuses 1, der an den Lager- bzw. Polgehäuse deckel 2 angrenzt. Bei diesem Ausführungsbeispiel ist in die Wandung des Polgehäuses eine Durchbrechung bzw. eine Bohrung 3 eingebracht. Für die Funktion der Durchführung ist es jedoch ohne Belang, ob die Bohrung im Polgehäuse oder im Lager- bzw. Polgehäusedeckel eingebracht wird. The figure shows a section of a housing of a starting device, specifically the area of the pole housing 1, which is attached to the bearing or pole housing cover 2 adjoins. In this embodiment, an opening or a bore 3 is made in the wall of the pole housing. For the function of the bushing, it is irrelevant whether the hole is made in the pole housing or in the bearing or pole housing cover.
In die Bohrung 3 ist ein Anschlußbolzen 4 eingebracht, der an seinem oberen, außerhalb des Gehäuses liegenden Ende einen umlaufenden Vorsprung bzw. Kragen 5 aufweist. Unterhalb dieses Kragens befindet sich ein auf den Anschlußbolzen 3 aufgeschobener, in sich geschlossener Profilring 6. Dieser weist einen oberen Bereich 7 auf, dessen Außendurchmesser größer ist als der Innendurchmesser der Bohrung 3. Die untere Fläche des Kragens 5 ist, ebenso wie die Oberfläche des Profilrings 6, eben ausgebildet, so daß beide Teile flächig aneinanderliegen. A connecting bolt 4 is introduced into the bore 3 and has a circumferential projection or collar 5 at its upper end lying outside the housing. Below this collar there is a self-contained profile ring 6 pushed onto the connecting bolt 3. This has an upper region 7, the outer diameter of which is larger than the inner diameter of the bore 3. The lower surface of the collar 5 is just like the surface of the Profile rings 6, flat, so that both parts lie flat against each other.
Der Außendurchmesser des Anschlußbolzens 4 ist deutlich kleiner als der Innendurchmesser der Bohrung 3, so daß zwischen diesen Elementen ein Ringraum besteht, in den ein Teil des Profilrings hineinragt. Dieser untere Teil 8 des Profilrings 6 ist gegenüber dem oberen Bereich 7 abgesetzt und weist einen kleineren Außendurchmesser als dieser auf. Aus der Darstellung wird deutlich, daß der untere Teil 8 des Profilrings einerseits dichtend an der Innenfläche der Bohrung 3 und andererseits an der Außenfläche des Anschlußbolzens anliegt. The outer diameter of the connecting bolt 4 is significantly smaller than the inner diameter of the bore 3, so that between these elements there is an annular space into which a part of the profile ring projects. This lower part 8 of the profile ring 6 is offset from the upper region 7 and has a smaller outer diameter than this. From the illustration it is clear that the lower part 8 of the profile ring rests on the one hand sealingly on the inner surface of the bore 3 and on the other hand on the outer surface of the connecting bolt.
Der Anschlußbolzen 4 weist einen unteren Ansatz 9 auf, der einen deutlich geringeren AuBendurchmesser als der übrige Anschlußbolzen hat und mit einem Außengewinde versehen ist. Durch den abgegrenzten unteren Ansatz 9 entsteht eine Anlagefläche 10, auf die ein erster elektrischer Leiter, beispielsweise eine Erregerwicklungs-Schiene 11 aufgelegt werden kann. Die Schiene wird mit Hilfe einer Mutter 12 und einer zwischengelegten Unterlegscheibe 13 an dem Anschlußbolzen 4 festgespannt. The connecting pin 4 has a lower projection 9, which has a significantly smaller outer diameter than the rest of the connecting pin and with a External thread is provided. The defined lower extension 9 creates a contact surface 10 on which a first electrical conductor, for example an excitation winding rail 11, can be placed. The rail is clamped to the connecting bolt 4 with the aid of a nut 12 and an intermediate washer 13.
Die Schiene 11 ist so groß, daß sie zumindest in einen Bereich über die Außenfläche des Anschlußbolzens 4 vorspringt. Dadurch wird ein Isolierteil 14 zwischen der Erregerwicklungs-Schiene 11 und der Innenseite des Polgehäuses 1 festgespannt. Wenn die Mutter 12 auf dem unteren Ansatz 9 festgezogen wird, wird der Anschlußbolzen 4 in der Bohrung 3 des Polgehäuses 1 eingespannt. Die Oberseite des Anschlußbolzens 4 stützt sich über den Kragen 5 und über den oberen Bereich 7 des Profilrings 6 an der Außenseite des Polgehäuses 1 ab. Die Unterseite des Anschlußbolzens 4 verspannt sich über das Isolierteil 14, die Erregerwicklungs-Schiene 11 und die Mutter 12 an der Unterseite des Polgehäuses 1. Die Vorspannung des montierten Anschlußbolzens 4 in der Polgehäusedurchführung bzw. Bohrung 3 kann durch die Wahl eines härteren oder weicheren elastischen Materials für den Profilring 6 variiert werden. Dadurch, daß der Profilring 6 unter dem Kragen 5 des Anschlußbolzens 4 eingespannt ist, wird eine optimale Abdichtung des Anschlußbolzens an dem Polgehäuse erreicht. Gleichzeitig wird durch den elastischen Profilring eine Dämpfung von Vibrationen erreicht. Der Profilring kann beispielsweise aus Gummi hergestellt werden. In die Oberseite des Anschlußbolzens 4 ist ein Sackloch 15 mit einem Innengewinde 16 eingebracht. Auf die ebene Oberfläche des Kragens 5 kann ein zweiter elektrischer Leiter, beispielsweise eine Stromschiene 17 aufgelegt werden, die mit der Stromversorgung flir die Erregerwicklung verbunden ist. Die Stromschiene 17 wird mittels einer Schraube 18 an dem Anschlußbolzen 4 befestigt. Im vorliegenden Fall ist unter den Schraubenkopf eine Unterlegscheibe 19 eingebracht. The rail 11 is so large that it projects at least in one area over the outer surface of the connecting bolt 4. As a result, an insulating part 14 is clamped between the excitation winding rail 11 and the inside of the pole housing 1. When the nut 12 is tightened on the lower shoulder 9, the connecting bolt 4 is clamped in the bore 3 of the pole housing 1. The upper side of the connecting bolt 4 is supported on the collar 5 and on the upper region 7 of the profile ring 6 on the outside of the pole housing 1. The underside of the connecting bolt 4 clamps over the insulating part 14, the excitation winding rail 11 and the nut 12 on the underside of the pole housing 1. The pretensioning of the assembled connecting bolt 4 in the pole housing bushing or bore 3 can be made by choosing a harder or softer elastic Material for the profile ring 6 can be varied. Characterized in that the profile ring 6 is clamped under the collar 5 of the connecting bolt 4, an optimal sealing of the connecting bolt on the pole housing is achieved. At the same time, the elastic profile ring dampens vibrations. The profile ring can be made of rubber, for example. A blind hole 15 with an internal thread 16 is made in the upper side of the connecting bolt 4. A second electrical conductor, for example a busbar 17, which is connected to the power supply for the excitation winding, can be placed on the flat surface of the collar 5. The busbar 17 is fastened to the connecting bolt 4 by means of a screw 18. In the present case, a washer 19 is inserted under the screw head.
Die Herstellung der Polgehäusedurchführung geschieht folgendermaßen: The pole housing bushing is manufactured as follows:
Zunächst wird auf den Anschlußbolzen 4 der Profilring 6 aufgeschoben. Dann wird der Anschlußbolzen durch die Bohrung 3 in das Polgehäuse 1 eingesetzt. Nach dem Aufschieben des Isolierteils 14, das mit einer Bohrung versehen ist, deren Innendurchmesser dem des Außendurchmessers des Anschlußbolzens entspricht, wird der erste elektrische Leiter, die Erregerwicklungs-Schiene 11, auf den unteren Ansatz 9 des Anschlußbolzens 4 aufgeschoben. Anschließend wird die Unterlegscheibe 13 aufgebracht und die Mutter T2 festgezogen. Diese ist dadurch zugänglich, daß der Lager- bzw. Polgehäusedeckel 2 bei der Montage der Polgehäusedurchführung nicht aufgesetzt ist. First, the profile ring 6 is pushed onto the connecting bolt 4. Then the connecting bolt is inserted through the hole 3 into the pole housing 1. After pushing on the insulating part 14, which is provided with a bore whose inside diameter corresponds to that of the outside diameter of the connecting bolt, the first electrical conductor, the excitation winding rail 11, is pushed onto the lower shoulder 9 of the connecting bolt 4. Then the washer 13 is applied and the nut T2 is tightened. This is accessible in that the bearing or pole housing cover 2 is not fitted when the pole housing bushing is installed.
Beim Festziehen der Mutter 12 wird die oben beschriebene Verspannung des Anschlußbolzens 4 in dem Polgehäuse 1 erreicht. When tightening the nut 12, the above-described tensioning of the connecting bolt 4 in the pole housing 1 is achieved.
Wie in der Figur dargestellt, kann das Isolierteil 14 mit einer Nase 20 versehen sein, die der Lagefixierung einer Bürstenhalterplatte 21 dient, die ihrer seits mit einer Ausnehmung 22 versehen ist, in die die Nase 20 des Isolierteils 14 eingreift. As shown in the figure, the insulating part 14 can be provided with a nose 20, which serves to fix the position of a brush holder plate 21, its is provided with a recess 22 into which the nose 20 of the insulating part 14 engages.
Nach dem Festziehen der Mutter 12 kann der Lagerbzw. Polgehäusedeckel 2 auf übliche Weise an dem Polgehäuse 1 angebracht werden. Schließlich wird der zweite Leiter, die Stromschiene 17, am Anschlußbolzen 4 befestigt. After tightening the nut 12, the bearing or. Pole housing cover 2 are attached to the pole housing 1 in the usual way. Finally, the second conductor, the busbar 17, is attached to the connecting bolt 4.
Nach allem wird eine optimale elektrische Verbindung zwischen dem ersten Leiter, der ErregerwicklungsSchiene 11, und dem zweiten Leiter, der Stromschiene 17, durch den Anschlußbolzen 4 gewährleistet, der aus elektrisch leitendem Material besteht. Die elektrische Kontaktierung ist metallisch kraftschlüssig und unabhängig von der Wahl des Materials für das Isolierteil und/oder für den Profilring. Durch den eingespannten Profilring 6 wird eine optimale Sicherung gegen in das Polgehäuse eindringende Feuchtigkeit erreicht. Durch die Elastizität des Profilrings werden Vibrationen optimal gedämpft. After all, an optimal electrical connection between the first conductor, the excitation winding rail 11, and the second conductor, the busbar 17, is ensured by the connecting bolt 4, which consists of electrically conductive material. The electrical contact is metallic non-positive and independent of the choice of material for the insulating part and / or for the profile ring. The clamped profile ring 6 provides optimal protection against moisture penetrating into the pole housing. The elasticity of the profile ring optimally dampens vibrations.
