Die Erfindung betrifft ein Steckverbindergehäuse nach dem Oberbegriff des Anspruchs 1 . Derartige Steckverbindergehäuse beherbergen Kontaktelemente, die beispielsweise den elektrischen Strom, Lichtwellen oder auch pneumatische Signale weiterleiten.  The invention relates to a connector housing according to the preamble of claim 1.

Stand der Technik State of the art
Ein metallisches Steckverbindergehäuse wird beispielsweise dazu eingesetzt, um das Gehäuseinnere, dass die oben bereits erwähnten Kontaktelemente beinhaltet, elektromagnetisch abzuschirmen. A metallic connector housing is used, for example, to electromagnetically shield the housing interior, which includes the above-mentioned contact elements.
Die Qualität einer solchen Schirmung wird üblicherweise durch eine Mes- sung, einer so genannten Transferimpedanz (auch Kopplungswiderstand genannt), ermittelt. Je niedriger die Transferimpedanz, desto höher ist die Schirmwirkung des Steckverbindergehäuses. Die Ermittlung der Transferimpedanz gehört, für einen technischen Angestellten eines Prüflabores der Elektroindustrie, zu den geläufigen Aufgaben. The quality of such a shielding is usually determined by a measurement, a so-called transfer impedance (also called coupling resistance). The lower the transfer impedance, the higher the shielding effect of the connector housing. The determination of the transfer impedance belongs, for a technical employee of a testing laboratory of the electrical industry, to the common tasks.

Die Aufgabe der Erfindung besteht darin, ein Steckverbindergehäuse vorzuschlagen, das korrosionsbeständig ist und außerdem gute Schirmeigenschaften besitzt.  The object of the invention is to propose a connector housing which is resistant to corrosion and also has good shielding properties.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. The object is solved by the characterizing features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments of the invention are specified in the subclaims.
Ein Steckverbindergehäuse besteht in der Regel aus zwei Gehäuseteilen, einem Gehäuseoberteil und einem Gehäuseunterteil. Das Gehäuseoberteil wird in einer bestimmten Steckrichtung mit dem Gehäuseunterteil zu- sammengeführt. Es können noch weitere Gehäuseteile (oder Anbauteile) vorgesehen sein. Beispielsweise kann der Kabelabgang, der sich in der Regel am Gehäuseoberteil befindet, als zusätzliches Gehäuseteil vorgesehen sein. Der separate Kabelabgang ist über ein Gewinde in das Gehäuseoberteil einschraubbar. Das Gehäuseoberteil kann dann mehrere Positionen umfassen, in welche der Kabelabgang einschraubbar ist. Dies macht das Steckverbindergehäuse noch flexibler einsetzbar. A connector housing usually consists of two housing parts, an upper housing part and a lower housing part. The upper part of the housing is merged with the lower part of the housing in a certain direction of insertion. There may be additional housing parts (or attachments) may be provided. For example, the cable outlet, which is usually located on the upper housing part, may be provided as an additional housing part. The separate cable outlet can be screwed into the upper part of the housing via a thread. The upper housing part can then comprise several positions, in which the cable outlet can be screwed. This makes the connector housing even more flexible.
In der Regel sind das Gehäuseoberteil und das Gehäuseunterteil aus einem metallischen, elektrisch leitfähigen Material gefertigt. Dadurch ist das Steckverbindergehäuse robust genug, um in schwierigen industriellenIn general, the upper housing part and the lower housing part are made of a metallic, electrically conductive material. This makes the connector housing sturdy enough to handle in tough industrial environments
Umgebungen eingesetzt zu werden. Ein weiterer Vorteil liegt in der elektromagnetischen Schirmung der Außenwelt gegenüber dem Gehäuseinneren. In Industrieumgebungen sind Steckverbindergehäuse häufig Spritzwasser und/oder Chemikalien (beispielsweise Druckerfarbe von Druckmaschinen) ausgesetzt. Um das Steckverbindergehäuse vor Korrosion zu schützen, werden die einzelnen Gehäuseteile häufig mit einer Oberflächenbeschich- tung versehen. Vorteilhafterweise handelt es sich bei der Oberflächenbe- schichtung um eine Silanschicht. Man spricht dann auch von einer Silani- sierung des Steckverbindergehäuses. Der Begriff Gehäusehälfte wird in dieser Druckschrift gleichbedeutend mitEnvironments to be used. Another advantage lies in the electromagnetic shielding of the outside world relative to the housing interior. In industrial environments, connector housings are often exposed to splash water and / or chemicals (such as printing ink from printing presses). To protect the connector housing from corrosion, the individual housing parts are often coated with a surface coating. provided. Advantageously, the surface coating is a silane layer. One speaks then of a silanization of the connector housing. The term housing half is synonymous in this document with
Gehäuseober- und Gehäuseunterteil verwendet. Housing top and bottom housing used.
Nachdem zumindest eine der Gehäusehälften mit Kontaktelementen bestückt wurde und diese mit den einzelnen Leitern eines anzuschließenden Kabels verbunden wurden, werden die Gehäusehälften in Steckrichtung zusammengesteckt und anschließend beispielsweise miteinander verschraubt. Der Berührkontakt zwischen den zusammengesteckten Gehäusehälften findet auf so genannten Kontaktflächen statt. Die oben erwähnte Steckrichtung orientiert sich in der Regel an der axialen Achse der einzelnen Bauteile. After at least one of the housing halves has been equipped with contact elements and these have been connected to the individual conductors of a cable to be connected, the housing halves are plugged together in the insertion direction and then bolted together, for example. The contact between the mated housing halves takes place on so-called contact surfaces. The above-mentioned plugging direction is usually oriented on the axial axis of the individual components.
Bei der Oberflächenbeschichtung der Gehäusehälften wird immer auch eine Kontaktfläche einer Gehäusehälfte mitbeschichtet. Es kann sogar sein, dass die Kontaktflächen beider Gehäusehälften beschichtet sind. In the surface coating of the housing halves, a contact surface of a housing half is always co-coated. It may even be that the contact surfaces of both housing halves are coated.
Eine Oberflächenbeschichtung, insbesondere die oben angesprochene Silanisierung, verringert immer die elektrische Leitfähigkeit zwischen den Kontaktflächen der Gehäusehälften. Dadurch verringert sich auch die oben angesprochene Transferimpedanz und gleichzeitig verschlechtert sich die elektromagnetische Schirmwirkung solcher Steckverbindergehäuse. A surface coating, in particular the above-mentioned silanization, always reduces the electrical conductivity between the contact surfaces of the housing halves. This also reduces the above-mentioned transfer impedance and at the same time worsens the electromagnetic shielding effect of such connector housing.
Erfindungsgemäß wird das Problem dadurch behoben, dass eine Kontaktflä- che eines Gehäuseteils zur anderen Kontaktfläche des anderen Gehäuseteils eine Kante bildet. Der Berührkontakt zwischen den Kontaktflächen ist linienförmige ausgebildet. Beim Zusammenstecken der Gehäusehälften schneidet die Kante der einen Kontaktfläche in die Oberflächenbeschichtung der anderen Kontaktfläche ein. Die Oberflächenbeschichtung wird durchdrungen und so ein elektrischer Kontakt zwischen den Gehäusehälften hergestellt. According to the invention, the problem is solved in that a contact surface of one housing part to the other contact surface of the other housing part forms an edge. The contact between the contact surfaces is formed linear. When mating the housing halves, the edge of a contact surface cuts into the surface coating of the other contact surface. The surface coating is penetrated and thus made an electrical contact between the housing halves.
Anders ausgedrückt: Beim Zusammenstecken der beiden Gehäuseteile schabt die scharfe Kante der einen Kontaktfläche die Beschichtung auf der anderen Kontaktfläche ab, so dass das elektrisch leitende Grundmaterial des Gehäuseteils wieder zum Vorschein kommt. Gleichzeitig wird das Beschich- tungsmaterial auf der Kante der anderen Kontaktfläche abgetragen. So steht nunmehr die unbeschichtete Kante der einen Kontaktfläche linienförmig mit der unbeschichteten anderen Kontaktfläche in elektrisch leitendem Kontakt. In other words, when the two housing parts are plugged together, the sharp edge of one contact surface scrapes off the coating on the other contact surface, so that the electrically conductive base material of the housing part reappears. At the same time, the coating material is removed on the edge of the other contact surface. So now is the uncoated edge of a contact surface linearly with the uncoated other contact surface in electrically conductive contact.

Die Figur 1 zeigt eine perspektivische Darstellung eines Gehäuseoberteils. Das hier dargestellte Gehäuseoberteil 1 ist im Wesentlichen zylinderförmig ausgebildet. Es ist aber auch jede andere geometrische Form, beispielsweise quaderförmig, denkbar. Eine mögliche Gehäuseform ist in der oben bereits zitierten EP 957540 A2 der Anmelderin offenbart. Innenseitig ist das Gehäuseoberteil 1 mit einem umlaufenden Absatz 2 versehen, der den Innendurchmesser des Gehäuseoberteils 1 verengt. FIG. 1 shows a perspective view of an upper housing part. The housing upper part 1 shown here is essentially cylindrical. But it is also any other geometric shape, for example, cuboid, conceivable. A possible housing form is disclosed in the above-cited EP 957540 A2 of the applicant. On the inside, the upper housing part 1 is provided with a peripheral shoulder 2, which narrows the inner diameter of the upper housing part 1.
Oberhalb des umlaufenden Randes 2 verläuft die Kontaktfläche 3 des Gehäuseoberteils 1 . Die Figur 2 zeigt eine perspektivische Darstellung eines Gehäuseunterteils. Das Gehäuseunterteil 5 ist steckkompatibel zum Gehäuseoberteil 1 ausgebildet. Steckseitig umfasst Das Gehäuseunterteil 5 einen äußeren umlaufenden Rand 6. Entlang des umlaufenden Randes 6 ist innenseitig ein axial emporstehender Ring 7 angeformt. Above the peripheral edge 2 extends the contact surface 3 of the upper housing part. 1 FIG. 2 shows a perspective view of a housing lower part. The lower housing part 5 is plug-compatible with the upper housing part 1. On the plug side, the lower housing part 5 comprises an outer peripheral edge 6. Along the peripheral edge 6, an axially upstanding ring 7 is integrally formed on the inside.
Der Ring 7 umfasst eine umlaufende Einkerbung 8. Oberseitig der Einkerbung 8 (in Steckrichtung 15 betrachtet) ist ein gerader Bereich zu sehen, der eine erste Teilfläche 9b der Kontaktfläche des Gehäuseunterteils 5 bildet. Weiter oberhalb ist ein nach außen abgewinkelten Bereich 9a zu erkennen, der die zweite Teilfläche 9a der Kontaktfläche des Gehäuseunterteils 5 bildet. Die beiden Teilflächen schließen einen stumpfen Winkel miteinander ein, dessen Spitze eine Kante 9 bildet. Die Kante 9 steht bei zusammengesteckten Gehäuseteilen in Berührkontakt mit der Kontaktflä- che 3 des Gehäuseoberteils 1 . The ring 7 comprises a circumferential notch 8. On the upper side of the notch 8 (viewed in the insertion direction 15), a straight region is to be seen, which forms a first partial surface 9b of the contact surface of the housing lower part 5. Further above, an outwardly angled region 9a can be seen, which forms the second partial surface 9a of the contact surface of the housing lower part 5. The two partial surfaces form an obtuse angle, the tip of which forms an edge 9. The edge 9 is in mated housing parts in touching contact with the contact surface 3 of the upper housing part. 1
Die Figur 3 zeigt eine Schnittdarstellung der miteinander Zusammengesteckten Gehäuseteile 1 , 5. Hier ist gut zu erkennen, dass die Kante 9 der Kontaktfläche 9a, 9b des Gehäuseunterteils 5 die Kontaktfläche 3 des Gehäuseoberteils 1 nur in einem Punkt berührt. In einer dreidimensionalenFIG. 3 shows a sectional view of the housing parts 1, 5 which are plugged together. Here, it can be clearly seen that the edge 9 of the contact surface 9a, 9b of the housing lower part 5 contacts the contact surface 3 of the housing upper part 1 only at one point. In a three-dimensional
Darstellung wird dieser Punkt linienförmig. Representation, this point becomes linear.
Beim Zusammenstecken der Gehäuseteile 1 , 5 wirkt die oben beschriebene Kante 9 wie eine Schneide, die die Beschichtung des Gehäuseoberteils 1 wegschabt, so dass die unbeschichtete Oberfläche zum Vorschein kommt. Durch die Reibkräfte wird gleichzeitig das Beschichtungsmaterial auf der Kante 9 abgetragen, so dass sich die nunmehr unbeschichteten Bereiche der Gehäuseteile 1 , 5 berühren.

Due to the frictional forces, the coating material on the edge 9 is simultaneously removed, so that the now uncoated areas of the housing parts 1, 5 touch. LIST OF REFERENCE NUMBERS
