Description
Die Erfindung bezieht sich auf eine druckdichte Kontakteinrichtung für einen druckdicht gekapselten Elektromotor zum Antrieb eines Kompressors gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a pressure-tight contact device for a pressure-tight encapsulated electric motor for driving a compressor according to the preamble of patent claim 1.
Bei Luftfederungen für Straßenfahrzeuge, mit denen sich gleichzeitig auch eine Niveauregulierung des Fahrzeugs realisieren läßt, wird Druckluft zur Versorgung der Luftfederbälge benötigt. Damit läßt sich das Niveau der Ladefläche eines Lkw's oder der Bodenabstand eines Pkw's auch bei wechselnder Beladung konstant halten.In air suspensions for road vehicles, with which also a level control of the vehicle can be realized at the same time, compressed air is required to supply the air spring bellows. Thus, the level of the loading area of a truck or the ground clearance of a car can be kept constant even with changing load.
Eine solche Niveauregulierung ist beispielsweise aus dem
Aus diesem Grund geht man, insbesondere bei Niveauregulierungen für Pkw, dazu über, geschlossene bzw. teilgeschlossene Systeme zu verwenden. Bei derartigen geschlossenen Systemen wird die überschüssige Druckluft beim Absenken des Fahrzeugs nicht ins Freie abgelassen, sondern durch den Kompressor in den Druckbehälter zurückgefördert.For this reason, especially in the case of level controls for passenger cars, it is necessary to use closed or partially closed systems. In such closed systems, the excess compressed air is not discharged to the outside when lowering the vehicle, but fed back through the compressor in the pressure vessel.
Bei teilgeschlossenen Systemen besteht die Möglichkeit, über Undichtigkeiten verlorene Luft bei Bedarf wieder aus der Atmosphäre anzusaugen.In partially closed systems, it is possible to suck back lost air from the atmosphere if necessary.
Dabei ist es bekannt, den Kompressor und den zu dessen Antrieb nötigen Elektromotor in einem gemeinsamen Druckbehälter anzuordnen. Dies führt zu einer geringeren Belastung des Kompressors, da dieser auf beiden Seiten seines mit einem Rückschlagventil versehenen Förderkolbens mit Druckluft beaufschlagt ist (siehe
Bei einer solchen gemeinsamen Kapselung von Motor und Kompressor ergibt sich jedoch das Problem, die elektrischen Anschlußleitungen für die Stromversorgung des Elektromotors sowie für eventuelle weitere Signalleitungen druckdicht aus der gemeinsamen Kapselung heraus zu führen. Die Anschlußleitungen werden dabei an eine Anschlußbuchse bzw. eine Kontakteinrichtung für ein elektrisches Verbindungskabel angeschlossen.In such a common encapsulation of the engine and compressor, however, the problem arises to pressure-tightly lead the electrical leads for the power supply of the electric motor and for any other signal lines from the common enclosure out. The leads are connected to a socket or a contact device for an electrical connection cable.
Der Erfindung liegt die Aufgabe zu Grunde, eine solche druckdichte Kontakteinrichtung anzugeben, welche einfach und kostengünstig herstellbar ist, dauerhaft druckdicht ist, und deren elektrische Anschlußbuchse für unterschiedliche Anschlußkabel geeignet sein soll.The invention is based on the object to provide such a pressure-tight contact device, which is simple and is inexpensive to produce, is permanently pressure-tight, and whose electrical connector is to be suitable for different cables.
Diese Aufgabe wird durch die im Patentanspruch 1 enthaltene Erfindung gelöst. Die Unteransprüche enthalten zweckmäßige Weiterbildungen.This object is achieved by the invention contained in claim 1. The dependent claims contain expedient developments.
Ein wesentlicher Vorteil der erfindungsgemäßen Kontakteinrichtung liegt darin, daß sie einerseits aus gleichbleibenden Teilen, nämlich in der Regel zwei Kontaktstiften zum Anschluß des Motors und einem die Kontaktstifte tragenden Isolierstoffteil besteht, daß aber andererseits für den Anschluß verschiedenartiger Anschlußkabel ein individuell geformtes Steckergehäuse auf das Isolierstoffteil aufsteckbar ist. Hierdurch ist die Kontakteinrichtung in einfacher Weise für je nach Anwender bzw. Fahrzeughersteller unterschiedlich benutzte Anschlußkabel herstellbar bzw. umrüstbar. Eine Lagerhaltung verschiedener Stecker-Varianten wird so vermieden.A major advantage of the contact device according to the invention is that on the one hand from constant parts, namely usually two pins for connecting the motor and a contact pins carrying insulating material consists, but that on the other hand for connecting different types of connection cable an individually shaped connector housing attachable to the Isolierstoffteil is. As a result, the contact device in a simple manner for each user or vehicle manufacturer differently used connection cable manufactured or convertible. A storage of different plug variants is avoided.
Durch die Abdichtung mit O-Ringen wird im Vergleich zu einer auch denkbaren Abdichtung durch Vergiessen oder Umspritzen eine bessere Dauer-Dichtigkeit auch bei wechselnden Temperaturen erzielt.By sealing with O-rings, in comparison to a conceivable seal by casting or encapsulation better permanent tightness is achieved even at changing temperatures.

In der Fig. 1 ist in schematischer Darstellung ein Schnitt durch die erfindungsgemäße Kontakteinrichtung dargestellt.1 shows a schematic representation of a section through the contact device according to the invention.
Mit (1) ist ein druckdichtes Gehäuse bezeichnet, in welches ein Elektromotor(M) (12) zum Antrieb eines (nicht dargestellten) Kompressors eingebaut ist. Das Gehäuse (1) kann unter einem Gas- oder Fluid-Druck von beispielsweise 10 bar stehen. Der Motor (12) ist über eine Leitung (21) an einen von in der Regel zwei Kontaktstiften (4) angeschlossen. Die Kontaktstifte (4) sind von unten in ein Isolierstoffteil (2) eingepreßt und werden dort durch zackenartige Vorsprünge (13) mechanisch gehalten. Zur Abdichtung zwischen dem Isolierstoffteil (2) und dem Kontaktstift (4) dient ein O-Ring (5).With (1) a pressure-tight housing is referred to, in which an electric motor (M) (12) is installed for driving a (not shown) compressor. The housing (1) can be under a gas or fluid pressure of for example 10 bar. The motor (12) is connected via a line (21) to one of usually two contact pins (4). The contact pins (4) are pressed from below into an insulating part (2) and are held there mechanically by serrated projections (13). For sealing between the insulating part (2) and the contact pin (4) is an O-ring (5).
Das Isolierstoffteil (2) ist mit einem weiteren O-Ring (3) gegenüber dem Gehäuse (1) abgedichtet. Hierdurch ist ein Entweichen des Druckmittels aus dem Gehäuse (1) ausgeschlossen.The insulating part (2) is sealed with a further O-ring (3) relative to the housing (1). As a result, an escape of the pressure medium from the housing (1) is excluded.
Auf das Isolierstoffteil (2) ist von unten ein Steckergehäuse (7) aufgesteckt bzw. aufgedrückt, welches gegen das Isolierstoffteil (2) mit einem weiteren O-Ring (8) abgedichtet ist. Das Steckergehäuse (7) ist mittels Verbindungsmitteln (9,10; 22,23) mit dem Gehäuse (1) fest verbunden. In der Fig. 1 erfolgt diese Verbindung durch Schrauben (9,10). Es ist auch möglich, das Steckergehäuse (7) an das Isolierstoffteil (2) anzuschrauben (nicht dargestellt).On the insulating part (2) from below a plug housing (7) is plugged or pushed, which is sealed against the insulating part (2) with a further O-ring (8). The plug housing (7) is fixedly connected to the housing (1) by means of connecting means (9, 10, 22, 23). In Fig. 1, this connection is made by screws (9,10). It is also possible to screw the plug housing (7) to the insulating part (2) (not shown).
Gemäß Fig 2 erfolgt die Verbindung durch eine spielfreie Schnappverbindung zwischen Steckergehäuse (7) und Isolierstoffteil (2). Diese besteht zum Beispiel aus Nasen (22,23), welche am Steckergehäuse (7) angeformt sind und in entsprechende Ausnehmungen des Isolierstoffteils (2) eingreifen.According to Figure 2, the connection is made by a play-free snap connection between the connector housing (7) and insulating part (2). This consists for example of lugs (22,23) which are integrally formed on the plug housing (7) and engage in corresponding recesses of the insulating part (2).
In beiden Fällen ist eine sichere Befestigung des Steckergehäuses (7) am Isolierstoffteil (2) bzw. am Gehäuse (1) gewährleistet.In both cases, a secure attachment of the plug housing (7) on the insulating part (2) or on the housing (1) is ensured.
Beim Aufstecken des Steckergehäuses (7) auf das Isolierstoffteil (2) durchdringt eine Spitze (14) des Kontaktstiftes (4) eine Ausstanzung (15) einer flachen Kontaktzunge (6) (siehe Fig. 3). Dabei bildet die Ausstanzung (15) mehrere Kontaktflächen (20), die im montierten Zustand der Kontakteinrichtung mit hoher Vorspannkraft am Kontaktstift (4) anliegen und eine elektrisch gut leitende Verbindung zwischen Kontaktstift (4) und Kontaktzunge (6) bewirken.When attaching the plug housing (7) on the insulating part (2) penetrates a tip (14) of the contact pin (4) has a punched-out (15) of a flat contact tongue (6) (see Fig. 3). In this case, the punch-out (15) forms a plurality of contact surfaces (20), which in the assembled state of the contact device with high biasing force abut the contact pin (4) and cause a good electrical connection between the contact pin (4) and contact tongue (6).
Die Kontaktzunge (6) ist in einem Schlitz (27) des Steckergehäuses (7) gelagert und durch Nasen (16) oder durch eine Durchbiegung (17) (siehe Fig. 4) im Steckergehäuse (7) festgelegt und so gegen Herausfallen beim Montagevorgang gesichert.The contact tongue (6) is mounted in a slot (27) of the plug housing (7) and fixed by lugs (16) or by a deflection (17) (see Fig. 4) in the connector housing (7) and secured against falling out during the assembly process ,
Die Kontaktzunge (6) hat gegenüber dem Steckergehäuse (7) soviel Spiel, das sich bei Ausdehnungen durch hohe Umgebungstemperaturen keine mechanischen Spannungen ergeben.The contact tongue (6) has compared to the connector housing (7) so much game that arise at expansions due to high ambient temperatures no mechanical stresses.
Die Kontaktzunge (6) ragt mit ihrem dem Kontaktstift (4) abgewandten Teil in ein Kragenteil (11), das eine Anschlußbuchse (28) für ein Anschlußkabel (25) (siehe Fig 6) bildet.The contact tongue (6) protrudes with its part remote from the contact pin (4) into a collar part (11), which forms a connection socket (28) for a connection cable (25) (see FIG. 6).
Die Fig. 5 zeigt eine Draufsicht von vorne auf die mit dem Steckergehäuse (7) verbundene, hier zweipolig ausgeführte Anschlußbuchse (28) mit dem Kragenteil (11) und den zwei nebeneinanderliegenden Kontaktzungen (6). Aus der Fig. 5 geht weiter hervor, daß das Steckergehäuse (7) mit einer Prüfbohrung (18) zur Dichtigkeitsprüfung des Gehäuses versehen sein kann. Derartige Dichtigkeitsprüfungen sind dem Fachmann bekannt. Anstelle einer Prüfbohrung (18) kann auch ein oberhalb einer Kontaktzunge (6) liegender Prüfkanal (19) zur Dichtigkeitsprüfung verwendet werden.Fig. 5 shows a plan view from the front of the connected to the plug housing (7), here two-pole running connector (28) with the collar part (11) and the two adjacent contact tongues (6). From Fig. 5 it is further apparent that the plug housing (7) can be provided with a test bore (18) for leak testing of the housing. Such leak tests are known in the art. Instead of a test bore (18), a test channel (19) lying above a contact tongue (6) can also be used for leak testing.
In der Fig. 6 ist eine Draufsicht auf eine hier dreipolig ausgeführte Anschlußbuchse (28) des Steckergehäuses (7) dargestellt. In diesem Fall besitzt das Steckergehäuse (7) drei nebeneinander liegende flache Kontaktzungen (6) zur Ansteuerung bzw. Versorgung des Motors (12) sowie eines weiteren, nicht dargestellten Bauteils im Gehäuse (1), zum Beispiel eines Sensors. Wie man sieht, werden die Kontaktzungen (6) an ihren Ausstanzungen (15) von den Kontaktstiften (4) unter Bildung einer elektrisch leitenden Verbindung durchstoßen.6 shows a plan view of a three-pin bushing (28) of the plug housing (7). In this case, the plug housing (7) has three adjacent flat contact tongues (6) for controlling or supplying the motor (12) and another, not shown, component in the housing (1), for example a sensor. As can be seen, the contact tongues (6) are pierced at their cutouts (15) by the contact pins (4) to form an electrically conductive connection.
Weiter ist in der Fig. 6 in die Anschlußbuchse (28) ein passendes Steckerteil (24) mit einem Anschlußkabel (25) eingesteckt. Das Steckerteil (24) wird durch einen O-Ring (26) abgedichtet. Hierdurch soll das Eindringen von Schmutz in die Kontaktzone verhindert werden. Das Steckerteil (24) ist in bekannter Weise mit Buchsen zur Aufnahme der Vorderenden der Kontaktzungen (6) versehen.Next, in Fig. 6 in the socket (28) a matching plug part (24) with a connecting cable (25) inserted. The plug part (24) is sealed by an O-ring (26). This is to prevent the ingress of dirt into the contact zone. The plug part (24) is provided in a known manner with sockets for receiving the front ends of the contact tongues (6).
Anstelle von durchgehend flachen Kontaktzungen (6) können auch Kontaktzungen verwendet werden, die an dem dem Steckerteil (24) zugewandten Ende als Stifte oder als Buchsen zur Aufnahme von Stiften des Steckerteils (24) ausgebildet sein.Instead of continuous flat contact tongues (6) and contact tongues can be used, which are formed on the plug part (24) facing the end as pins or bushings for receiving pins of the plug part (24).
Die erfindungsgemäße druckdichte Kontakteinrichtung, die im Ausführungsbeispiel zur Versorgung eines druckdicht gekapselten Elektromotors dient, kann natürlich auch zur Versorgung oder Steuerung anderer druckdicht gekapselter Geräte eingesetzt werden.The pressure-tight contact device according to the invention, which serves in the embodiment for supplying a pressure-tight encapsulated electric motor, can of course also be used to supply or control other pressure-tight encapsulated devices.
Der Motor (M) kann anstelle eines Kompressors auch eine Vacuumpumpe antreiben.The engine (M) can also drive a vacuum pump instead of a compressor.
