Description

Die Erfindung betrifft einen Steckverbinder zur Leitungsdurchführung durch eine Öffnung einer Trennwand eines insbesondere militärischen Gerätes mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a connector for line bushing through an opening of a partition of a particular military device with the features of the preamble of claim 1.

Derartige Steckverbinder sind allgemein bekannt z. B aus Dokument DE 29905566U . Sie sollen insbesondere bei ihrer Anwendung an militärischen Geräten folgende Eigenschaften aufweisen:

  1. a) eine gute elektromagnetische Verträglichkeit (EMV),
  2. b) eine gute Resistenz gegen Umwelteinflüsse, insbesondere Korrosion durch Salzsprühnebel, wie sie beim Abschuss von Geschossen oder Raketen auftreten,
  3. c) eine matte, insbesondere aus Gründen der Tarnung oliv gefärbte Oberfläche der nach außen sichtbaren Flächen.
Such connectors are well known for. B from document DE 29905566U , They should have the following properties, in particular when used on military equipment:
  1. a) good electromagnetic compatibility (EMC),
  2. b) a good resistance to environmental influences, in particular corrosion by salt spray, as they occur when launching missiles or missiles,
  3. c) a matte, especially for the sake of camouflage olive colored surface of the outwardly visible surfaces.

Diese Bedingungen wurden bisher u.a. dadurch erfüllt, dass alle Oberflächen der Teile der Steckverbindung eine Nickelschicht aufwiesen, über welche eine cadmiumhaltige Schicht aufgebracht wurde, die anschließend grün chromatiert wurde. Dieser Schichtaufbau erfüllt die oben genannten Anforderungen bezüglich der elektromagnetischen Verträglichkeit, des Korrosionsschutzes und der Einfärbung.These conditions were previously u.a. fulfilled in that all surfaces of the parts of the connector had a nickel layer over which a cadmium-containing layer was applied, which was then green chromated. This layer construction fulfills the above-mentioned requirements with regard to the electromagnetic compatibility, the corrosion protection and the coloring.

Da cadmiumhaltige Stoffe als gesundheitlich nicht unbedenklich gelten, wurde die Forderung erhoben, für militärische Projekte nach Möglichkeit cadmiumfreie Steckverbinder einzusetzen.Since cadmium-containing substances are considered to be harmful to health, the demand was made to use cadmium-free connectors for military projects wherever possible.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 so auszugestalten, dass alle oben genannten Bedingungen erfüllt sind, ohne dass die Oberflächen der Teile des Steckverbinders cadmiumhaltige Stoffe enthalten müssen.The invention has for its object to design a connector with the features of the preamble of claim 1 so that all the above conditions are met without the surfaces of the parts of the connector must contain cadmium-containing substances.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The solution of this object is achieved according to the invention with the features of the characterizing part of claim 1. Advantageous developments of the invention are described in the dependent claims.

Die Erfindung geht von der Erkenntnis aus, dass, um eine gute elektromagnetische Verträglichkeit (EMV) zu erreichen, es nicht unbedingt erforderlich ist, alle Teile der Steckverbindung elektrisch leitend auszugestalten oder mit einer elektrisch leitenden Oberfläche zu versehen. Es reicht vielmehr aus, wenn entlang der Steckverbindung durchgehende und miteinander in gutem Kontakt stehende elektrisch leitende Oberflächen vorgesehen sind. Dies müssen aber nicht notwendig alle nach außen sichtbaren Oberflächen sein. Bei dem erfmdungsgemäßen Steckverbinder befinden sich die elektrisch leitfähig auszulegenden Komponenten überwiegend im nach außen nicht sichtbaren Teil der Steckverbindung, während viele der nach außen sichtbaren Einzelkomponenten für die elektrische Leitfähigkeit nicht relevant sind. Gemäß den Merkmalen a) und b) des Schutzanspruchs 1 wird eine sehr gute durchgehende elektrische Leitfähigkeit dadurch erreicht, dass die elektrisch leitfähig auszugestaltenden Komponenten der Steckverbindung an mindestens einer inneren oder äußeren durchlaufenden Oberfläche mit einer cadmiumfreien, elektrisch leitenden Oberflächenbeschichtung versehen sind, und zur Sicherstellung eines guten elektrischen Kontaktes zwischen diesen elektrisch leitfähigen Einzelkomponenten sind die Kontaktstellen zwischen den Grundkörpern der Steckerteile und den Grundkörpern der Kabeladapter als ineinandergreifende Verzahnungen ausgebildet, und die Kontaktstelle zwischen den Grundkörpern der Gerätesteckdose und des Steckers wird durch einen mit dem einen Grundkörper verbundenen Massering bewirkt, der mit federnden, sich jeweils an eine Oberfläche des anderen Grundkörpers anlegenden Zungen versehen ist. Gemäß Merkmal c) des Schutzanspruchs 1 sind weiterhin die Einzelkomponenten des Steckverbinders, die nach außen sichtbare Oberflächen besitzen und die nicht notwendig eine elektrische Leitfähigkeit aufweisen müssen, mit einer matten, gegenüber Umwelteinflüssen resistenten, cadmiumfreien Oberfläche versehen. Diese Oberfläche kann elektrisch isolierend ausgeführt sein. Diese Einzelkomponenten, bei denen keine elektrische Leitfähigkeit erforderlich ist, können auch insgesamt aus isolierendem Material, beispielsweise aus Kunststoff bestehen.The invention is based on the recognition that, in order to achieve a good electromagnetic compatibility (EMC), it is not absolutely necessary to make all parts of the plug-in connection electrically conductive or to provide it with an electrically conductive surface. Rather, it is sufficient if there are continuous and mutually in good contact electrically conductive surfaces along the connector. But this need not necessarily be all externally visible surfaces. In the case of the plug connector according to the invention, the components which are to be designed to be electrically conductive are located predominantly in the part of the plug connection which is not visible from the outside, while many of the individual components which are visible from the outside are not relevant for the electrical conductivity. According to the features a) and b) of the protection claim 1, a very good continuous electrical conductivity is achieved in that the components of the plug connection to be designed in an electrically conductive manner are provided on at least one inner or outer continuous surface with a cadmium-free, electrically conductive surface coating, and to ensure a good electrical contact between these electrically conductive individual components, the contact points between the main bodies of the connector parts and the body of the cable adapter are formed as interlocking teeth, and the contact point between the main body of the device socket and the plug is effected by a connected to the one body mass ring, which with resilient, respectively provided on a surface of the other body abutting tongues. According to feature c) of claim 1 protection are further the individual components of the connector, which have surfaces visible to the outside and not necessarily have to have an electrical conductivity, provided with a matte, resistant to environmental influences, cadmium-free surface. This surface can be made electrically insulating. These individual components, in which no electrical conductivity is required, can also consist entirely of insulating material, for example made of plastic.

Bei einer besonders vorteilhaften Ausführungsform des erfindungsgemäßen Steckverbinders besteht die elektrisch leitfähige Oberflächenbeschichtung aus Nickel und vorzugsweise aus einer mehrschichtig aufgebrachten Nickelbeschichtung, die unter der Bezeichnung "Heavy Nickel" bekannt ist. Es können aber auch andere elektrisch leitfähige Oberflächenbeschichtungen eingesetzt werden, die beispielsweise aus Zinn, Zink oder Kupfer bestehen.In a particularly advantageous embodiment of the connector according to the invention, the electrically conductive surface coating of nickel and preferably of a multilayer applied nickel coating, which is known under the name "Heavy Nickel". However, it is also possible to use other electrically conductive surface coatings, which consist for example of tin, zinc or copper.

Wichtig bei der Auswahl der Beschichtungsmaterialien ist nicht nur ihre elektrische Leitfähigkeit und die Korrosionsbeständigkeit sondern auch die Stellung des Materials in der elektrochemischen Spannungsreihe.Important in the selection of coating materials is not only their electrical conductivity and corrosion resistance but also the position of the material in the electrochemical series.

Die matte, gegenüber Umwelteinflüssen resistente, cadmiumfreie Oberfläche gemäß Merkmal c) des Schutzanspruchs 1, kann auch bei aus Metall bestehenden Einzelteilen als eloxierte Metalloberfläche ausgeführt sein.The matte, cadmium-free surface resistant to environmental influences according to feature c) of claim 1 can also be designed as an anodized metal surface in the case of individual parts made of metal.

Es hat sich gezeigt, dass der in dieser Weise ausgestaltete erfindungsgemäße Steckverbinder eine ausgezeichnete elektromagnetische Verträglichkeit und sehr gute Korrosionsfestigkeit besitzt und mit einer matten, insbesondere oliv eingefärbten Oberfläche an den äußeren Flächen versehen werden kann, ohne dass cadmiumhaltige Stoffe eingesetzt werden müssen.It has been found that the connector according to the invention designed in this manner has excellent electromagnetic compatibility and very good corrosion resistance and can be provided with a matt, in particular olive-colored, surface on the outer surfaces, without having to use cadmium-containing substances.

The electrical contact between the main body 1.1 of the appliance socket 1 and the main body 2.1 of the plug 2 via a arranged on the plug ground ring 2.11, which is provided with resilient, applied to the inner wall of the plug 1.1 of the device socket tongues 2.12 4 and 5 ).

Die elektrische Kontaktierung zwischen dem Kabelanschlussteil 1.2 des Grundkörpers der Gerätesteckdose 1 bzw. dem Kabelanschlussteil 2.2 des Grundkörpers des Steckers 2 zu den Grundkörpern der Kabeladapter 3 und 4 erfolgt über Rundumverzahnungen 1.22 bzw. 2.22 an den Grundkörpern de Gerätesteckdose 1 bzw. des Steckers 2, welche in entsprechende Verzahnungen an den Grundkörpern der Kabeladapter 3 und 4 eingreifen, beispielsweise (Fig. 6) in die Verzahnung 4.11 am Grundkörper 4.1 des Kabeladapters 4.The electrical contact between the cable connection part 1.2 of the main body of the device socket 1 and the cable connection part 2.2 of the main body of the plug 2 to the main bodies of the cable adapter 3 and 4 via Rundumverzahnungen 1.22 or 2.22 to the main body de device socket 1 and the plug 2, which engage in corresponding teeth on the basic bodies of the cable adapters 3 and 4, for example ( Fig. 6 ) in the toothing 4.11 on the base 4.1 of the cable adapter. 4

Die nach außen sichtbare Rückseite des Befestigungsflansches 1.3 an der Gerätesteckdose 1 sowie die Außenflächen der Befestigungsmutter 1.4 sind mit einer cadmiumfreien, olivfarbenen, ggf. isolierenden matten Oberfläche versehen. Ebenso ist der nach außen sichtbare Verriegelungsring 2.3 des Steckers 2 sowie die Befestigungsüberwurfmuttem z.B. 4.2 der Kabeladapter 3 und 4 mit einer olivfarbenen, ggf. isolierenden matten, cadmiumfreien Oberfläche versehen. Die Klemmmuttern der Kabeladapter 3 und 4 z.B. 4.3 am Kabeladapter 4 können mit einer üblichen Nickeloberfläche versehen sein. Diese optimiert die elektrische Leitfähigkeit zum Abschirmgeflecht des Kabels hin. Eine Heavy-Nickel-Oberfläche ist hier nicht erforderlich, da die Klemmmuttern beim fertig montierten Steckverbinder jeweils von einem aufgeschrumpften Formteil z.B. 5 vor Sicht und Umwelteinflüssen geschützt sind.The visible to the outside of the rear mounting flange 1.3 on the device socket 1 and the outer surfaces of the mounting nut 1.4 are provided with a cadmium-free, olive-colored, possibly insulating matte surface. Likewise, the outwardly visible locking ring 2.3 of the plug 2 and the Befestigungsüberwurfmuttem eg 4.2 of the cable adapter 3 and 4 is provided with an olive, possibly insulating matt, cadmium-free surface. The clamping nuts of the cable adapters 3 and 4 eg 4.3 on the cable adapter 4 can be provided with a conventional nickel surface. This optimizes the electrical conductivity towards the shielding braid of the cable. A heavy-nickel surface is not required here, since the clamping nuts are protected by a shrunk-on molded part, for example in the fully assembled connector, for example from the point of view and environmental influences.

Die matten Oberflächen der Bauteile, bei denen die elektrische Leitfähigkeit nicht erforderlich ist, können durch Eloxieren, Lackieren oder mechanisches Abdecken erreicht werden. Auch Kunststoff oder Komposit als Werkstoff ist hier denkbar. Die olivfarbene, matte Oberfläche muss resistent gegenüber den spezifizierten Umwelteinflüssen sein. Diese Bauteiloberflächen sind nichtleitend und somit elektrochemisch neutral. Daher ist die Steckkompatibilität zu herkömmlichen Steckern der jeweiligen Norm weiterhin gewährleistet. Die chemische Spannungsreihe der leitfähigen Steckerteile des oben beschriebenen Steckverbinders zu herkömmlichen Ausführungsformen bleibt unverändert, da diese unter ihrer Cadmierung ebenfalls vernickelt sind.The matte surfaces of the components, where electrical conductivity is not required, can be achieved by anodizing, painting or mechanical masking. Also plastic or composite as a material is conceivable here. The olive-colored, matte surface must be resistant to the specified environmental influences. These component surfaces are non-conductive and thus electrochemically neutral. Therefore, the plug compatibility with conventional plugs of the respective standard is still guaranteed. The chemical voltage series of the conductive connector parts of the connector described above to conventional embodiments remains unchanged, since they are also nickel plated under their Cadmierung.

Bei einer Ausführungsform des oben beschriebenen Steckverbinders, bei welcher der Flansch der Gerätesteckdose als Vierloch-Befestigungsflansch ausgebildet ist, sind beide Seiten des Befestigungsflansches als Kontakt- und Anschraubfläche mit einer Heavy-Nickel-Oberfläche versehen. Sollte in diesem Fall die Gerätesteckdose nicht im Gehäuse eingebaut verwendet werden, kann bei Bedarf der glänzende Teil des Flansches durch oliv gefärbte Abdeckungen überdeckt werden.In one embodiment of the connector described above, in which the flange of the device socket is designed as a four-hole mounting flange, both sides of the mounting flange are provided as a contact and mounting surface with a heavy-nickel surface. If, in this case, the device socket is not installed in the housing, the glossy part of the flange can be covered by olive-colored covers if necessary.
