Abstract
Description
Die vorliegende Erfindung betrifft ein Gerät zum Reinigen der Kontakt flächen von Stiften und/oder Hülsen elektrischer Steckverbindungen.The present invention relates to a device for cleaning the contact surfaces of pins and / or sleeves of electrical connectors.
Die wesentlichen Teile elektrischer Steckverbindungen bestehen aus elektrisch leitenden Stiften/ Hülsenkombinationen unterschiedlichster Ausführungsformen mit isolierenden Ummantelungen, wobei die Stifte oder Hülsen beziehungsweise Klemmen aus Kupferlegierungen üblicherweise gestaltet werden. Sofern diese elektrischen Steckverbindungen häufig unterbrochen werden und der Witterung beziehungsweise aggressiven atmosphärischen Einflüssen ausgesetzt sind, bilden sich auf den Kontaktflächen Oxydschichten und Korrosionen, die eine einwandfreie elektrische Verbindung behindern durch Erhöhung des Übergangswiderstandes. Im Niederspannungsbereich führt diese Erscheinung zu Ausfällen, im Bereich höherer Spannungen können Teile der Steckverbindung durch die entstehende Stromwärme zerstört werden.The essential parts of electrical plug connections consist of electrically conductive pins / sleeve combinations of the most varied of embodiments with insulating sheaths, the pins or sleeves or clamps usually being made of copper alloys. If these electrical plug connections are frequently interrupted and are exposed to the weather or aggressive atmospheric influences, oxide layers and corrosion form on the contact surfaces, which impede a perfect electrical connection by increasing the contact resistance. In the low voltage range, this phenomenon leads to failures, in the higher voltage range, parts of the plug connection can be destroyed by the resulting heat of electricity.
Man hat daher bereits zur Kontaktverbesserung edelmetallbeschichtete Steckverbindungen eingeführt, die jedoch nur für Spezialzwecke wegen des Preises infrage kommen. Im allgemeinen Gebrauch gibt es auch mit korrosionsbeständigen Metallen beschichtete Steckverbindungen, deren Beschichtung sich jedoch beim häufigen Gebrauch abnutzt.It has therefore already been introduced to improve contact, precious metal-coated connectors, but only for special purposes because of Price. In general use there are also plug connections coated with corrosion-resistant metals, the coating of which, however, wears out with frequent use.
Es bestand daher die Aufgabe, ein einfach zu handhabendes und kostengünstig herstellbares Gerät zu entwickeln, mit dem man die Stifte und Hülsen elektrischer Steckverbindungen bei Bedarf bequem reinigen kann, ohne die elektrischen Steckverbindungen ausbauen oder zerlegen zu müssen.It was therefore the task of developing an easy-to-use and inexpensive to produce device with which one can conveniently clean the pins and sleeves of electrical plug connections if required, without having to remove or dismantle the electrical plug connections.
Diese Aufgabe wird erfindungsgemäss mit einem Gerät gelöst, das die Form eines Stabes und/oder Rohres aufweist, deren Oberflächen ganz oder teilweise einen Reibbelag aufweisen.This object is achieved according to the invention with a device which has the shape of a rod and / or tube, the surfaces of which have a friction lining in whole or in part.
Vorteilhafte Ausführungsformen bestehen darin, dass das Gerät einen oder mehrere Längsschlitze aufweist, dass es aus einem zur Verarbeitung in Spritzmaschinen geeigneten Kunststoff besteht, dass es einen gegen elektrische Spannungen isolierenden Handgriff aufweist und ferner, dass es alternativ zum Längsschlitz wenigstens einen Schlitz aufweist, der nach Art einer Wendel verläuft insbesondere mit einem Anstieg von mehr als 45°.Advantageous embodiments consist in that the device has one or more longitudinal slots, that it consists of a plastic suitable for processing in injection molding machines, that it has a handle that insulates against electrical voltages, and that, as an alternative to the longitudinal slot, it has at least one slot that follows Kind of a spiral runs in particular with an increase of more than 45 °.
In der einfachsten Form besteht das Gerät aus einem Stab mit kreisförmigem Querschnitt und einem wenigstens im Endbereich aufgebrachten Reibbelag. Er wird mit diesem Ende in die zu reinigende Steckerhülse eingeführt und die Hülse durch Drehbewegungen des Stabes oder durch Hinundherbewegen von den kontaktbehindernden oberflächlichen Verunreinigungen befreit. Entsprechend gestaltet ist das Gerät in Rohrform, welches zur Reinigung der Steckerstifte dient und in entsprechender Weise gehandhabt wird. Das Gerät in Rohrform kann darüber hinaus auf seiner Innen- und auf seiner Aussenseite einen Reibbelag aufweisen; es kann dann zum Reinigen von Stiften und Hülsen unterschiedlicher Kalibrierungen dienen.In its simplest form, the device consists of a rod with a circular cross-section and a friction lining applied at least in the end region. It is inserted with this end into the plug sleeve to be cleaned and the sleeve is freed from the contact-impeding surface impurities by rotating the rod or by moving it back and forth. The device in Rohr is designed accordingly form, which is used to clean the connector pins and is handled in a corresponding manner. The tube-shaped device can also have a friction lining on its inside and outside; it can then be used to clean pins and sleeves of different calibrations.
Selbstverständlich sind auch Kombinationen von Stab-und Rohrform, zum Beispiel am einen Ende Rohrform, .` am anderen Ende Stabform, möglich und zweckmässig; ebenso sind Kombinationen von Stäben mit zwei oder mehr Kalibrierungen möglich, wobei die Enden bei- 'spielsweise die Spitzen eines Dreiecks, die Enden eines Kreuzes, eines sonstigen Vielecks oder auch eines räumlichen Gebildes darstellen. Gleiches gilt für die Kombinationen in Rohrform und gemischte Kombinationen aus Rohr- und Stabform. Auf diese Weise erhält man beispielsweise bei der Anordnung in Kreuzform vier Kalibrierungen, ausgehend von der Stabform und je vier Kalibrierungen, ausgehend von der Rohrform für vier verschiedene Stift- oder Hülsenabmessungen.Of course, combinations of rod and tube shape, for example tube shape at one end, .` rod shape at the other end, are possible and expedient; combinations of rods with two or more calibrations are also possible, the ends representing, for example, the tips of a triangle, the ends of a cross, another polygon or else a spatial structure. The same applies to the combinations in tube form and mixed combinations of tube and rod form. In this way, four calibrations based on the rod shape and four calibrations based on the tube shape for four different pin or sleeve dimensions are obtained, for example, when arranged in a cross shape.
Die Abmessungen des Gerätes haben naturgemäss den Abmessungen der zu reinigenden Steckverbindungen zu entsprechen, das heisst, der Durchmesser des stabförmigen Gerätes oder Geräteteiles sollte nur geringfügig kleiner sein als der Innenteil der zu reinigenden Steckerhülse und der Innendurchmesser des rohrförmigen Gerätes oder Geräteteiles geringfügig grösser als der Durchmesser des zu reinigenden Steckerstiftes. Das bedingt zwar, dass für verschiedene Steckverbindungen auch verschiedene Reinigungsgeräte mit den entsprechenden Dimensionierungen erforderlich sind, jedoch ist die Herstllung derartiger Geräte so einfach und preisgünstig, dass dies keinen Nachteil bedeutet, insbesondere, wenn man die oben beschriebenen Kombinationsmöglichkeiten ausnutzt. Diese Kombinationen ermöglichen es, für die beiden Teile einer Steckverbindung, welche unterschiedliche Dimensionierungen der Stifte aufweisen, ein einziges Reinigungsgerät herzustellen, zum Beispiel für sogenannte Eurosteckverbindungen. Im übrigen unterliegen Steckverbindungen weitgehend der Normung, sodass selbst für einen universellen Einsatz nicht allzuviel Kalibrierungen erforderlich wären.The dimensions of the device naturally have to correspond to the dimensions of the plug connections to be cleaned, i.e. the diameter of the rod-shaped device or device part should only be slightly smaller than the inner part of the plug sleeve to be cleaned and the inner diameter of the tubular device or device part slightly larger than the diameter of the connector pin to be cleaned. Although this means that different cleaning devices with the corresponding dimensions are required for different plug connections, the manufacture of such devices is so simple and inexpensive, that this is not a disadvantage, especially if you use the combination options described above. These combinations make it possible to produce a single cleaning device for the two parts of a plug connection, which have different dimensions of the pins, for example for so-called Euro plug connections. In addition, plug connections are largely subject to standardization, so that not too many calibrations would be necessary even for universal use.
Es ist auch möglich, die Stab- und/oder Rohrform des Gerätes polygonal zu gestalten, wobei dann die Reinigungswirkung von dem Reibbelag zunächst ausgeht, welcher sich aussen auf den Kanten oder innen im Rohr auf der Flächenmitte befindet. Bei zunehmender Abnutzung des Reibbelags kommen dann die benachbarten Partien des Belags zum Tragen.It is also possible to design the rod and / or tube shape of the device to be polygonal, the cleaning effect then starting from the friction lining, which is located outside on the edges or inside in the tube in the middle of the surface. With increasing wear of the friction lining, the adjacent areas of the lining come into play.
Zweckmässigerweise weist das Gerät einen oder mehrere Längsschlitze auf, die bei entsprechender Materialwahl ein federndes Zusammendrücken des Stabes oder Rohres gestatten, sodass beim Reinigungsvorgang der Reibbelag durch die Elastizität des Gerätes an die zu reinigende Oberfläche angedrückt wird. Das Gerät in Stabform mit einem oder mehreren Längsschlitzen kann auch an dem Längsschlitz einen Reibbelag aufweisen, sodass es zum Reinigen beispielsweise auch von Steckerflachstiften durch Aufschieben und Hinundherbewegen gebracht werden kann.The device expediently has one or more longitudinal slots which, with the appropriate choice of material, allow the rod or tube to be compressed resiliently, so that during the cleaning process the friction lining is pressed against the surface to be cleaned by the elasticity of the device. The rod-shaped device with one or more longitudinal slots can also have a friction lining on the longitudinal slot, so that it can also be brought in for cleaning, for example, of connector flat pins by sliding them on and moving them back and forth.
Weiterhin ist es vorteilhaft, wenn das erfindungsgemässe Gerät zum Reinigen von Kontaktflächen wenigstens einen Schlitz aufweist, der nach Art einer Wendel verläuft, insbesondere, wenn diese Wendel einen Anstieg von mehr als 45° aufweist. Dies hat den Vorteil, dass sich das Gerät beim Reinigungsvorgang aufgrund der Materialelastizität je nach Drehrichtung und dem Verlauf der Wendel weitet ( bei Hülsen ) und zusammenzieht ( bei Stiften ), wodurch der Reibbelag einen besseren Kontakt zur zu reinigenden Oberfläche findet. Geräte mit einem Anstieg der Wendel von 45° und weniger haben darüber hinaus den Vorteil, dass sie auch für an sich nicht vorgesehene Kalibrierungen bei federartiger Aufweitung gebraucht werden können. ( Der Begriff Anstieg ist hier so zu verstehen, dass ein 90°-Anstieg einem Längsschlitz parallel zur Achse entspricht).Furthermore, it is advantageous if the device according to the invention for cleaning contact surfaces does little least has a slot which extends in the manner of a helix, especially if this helix has an increase of more than 45 °. This has the advantage that the device expands during the cleaning process due to the material elasticity depending on the direction of rotation and the course of the helix (in the case of sleeves) and contracts (in the case of pins), as a result of which the friction lining makes better contact with the surface to be cleaned. Devices with an increase in the helix of 45 ° and less also have the advantage that they can also be used for calibrations that are not intended per se with a spring-like expansion. (The term increase is here to be understood such that a 9 0 ° -increase corresponds to a longitudinal slot parallel to the axis).
Das erfindungsgemässe Gerät kann aus den verschiedensten Materialien, insbesondere gegen elektrische Spannungen isolierenden Materialien, bestehen. Es besteht zweckmässigerweise aus einem zur Verarbeitung in Spritzmaschinen geeigneten Kunststoff mit einer gewissen Elastizität. Der Reibbelag kann durch Bespritzen, Bestreichen oder Tauchen im Anschluss an die Herstellung aufgebracht werden oder aber in Form eines Füllstoffs entsprechender Körnung bereits in der Masse enthalten sein. Für den Reibbelag geeignet ist ein feinkörniges Material, wie es üblicherweise für Schleif- und Polierzwecke bei Metallen eingesetzt wird.The device according to the invention can consist of a wide variety of materials, in particular materials that isolate against electrical voltages. It expediently consists of a plastic with a certain elasticity suitable for processing in injection molding machines. The friction lining can be applied by spraying, brushing or dipping after the production, or it can already be contained in the mass in the form of a filler of appropriate grain size. A fine-grained material is suitable for the friction lining, as is usually used for grinding and polishing purposes for metals.
Bei Auswahl geeigneter Kunststoffmaterialien für das Reinigungsgerät ist deren Isolierwirkung gegen elektrische Spannungen im allgemeinen ausreichend. Aus Sicherheitsgründen ist es jedoch zweckmässig, die Geräte mit einem Handgriff aus einer Spezialisolierung zu versehen, wobei der Handgriff so ausgebildet sein kann, dass das Gerät umstellbar und/oder auswechselbar gegen andere Reinigungsgeräte mit abweichenden Abmessungen ist.When selecting suitable plastic materials for the cleaning device, their insulating effect against electrical voltages is generally sufficient. For safety reasons, however, it is expedient to provide the devices with a handle made from a special insulation, the handle being able to be designed in such a way that the device can be converted and / or exchanged for other cleaning devices with different dimensions.
Das erfindungsgemässe Gerät zum Reinigen der Kontaktflächen von Stiften und/oder Hülsen elektrischer Steckverbindungen eignet sich praktisch für alle Anwendungsgebiete in Haushalt, Industrie, Handwerk, Landwirtschaft, Verkehr, Schiffahrt, Luftfahrt und im militärischen Bereich, insbesondere aber in den Bereichen, in denen aufgrund von Witterungseinflüssen oder aggressiver Atmosphäre, durch Seewasser, die Oxydbildung der Kontaktflächen begünstigt wird.The device according to the invention for cleaning the contact surfaces of pins and / or sleeves of electrical plug connections is suitable for practically all fields of application in the household, industry, handicraft, agriculture, traffic, shipping, aviation and in the military field, but in particular in the areas in which due to Weather influences or aggressive atmosphere, through sea water, the oxide formation of the contact surfaces is favored.
