Description
Eine wichtige Eigenschaft von Elektroisolierstoffen ist der Isolationswiderstand. Daher wird dieser sowohl von einer Reihe von Werkstoffherstellern, z.B. in der Kunststoffindustrie, wie auch von Materialverarbeitern und -anwendern laufend überprüft. Er findet oft Eingang in die Materialdatenblätter oder Überwachungsvorschriften.An important property of electrical insulating materials is insulation resistance. This is therefore continuously checked by a number of material manufacturers, e.g. in the plastics industry, as well as by material processors and users. It is often included in material data sheets or monitoring regulations.
Eine Meßvorschriften für den Isolationswiderstand ist der Norm DIN IEC 167 „Prüfverfahren für Elektroisolierstoffe", Beuth-Verlag, Berlin 1993 niedergelegt. Dort werden für die Meßelektroden unter anderem Striche aus leitender Farbe, 1 mm breit, (10 +/- 0,5) mm Abstand, (100 +/- 1 mm) lang festgelegt. Diese leitenden. Striche werden oft in der Praxis eingesetzt, da sie einfach aufzubringen sind. Allerdings weisen sie den Nachteil auf; daß ihre Herstellung in der Regel in Handarbeit erfolgt, mit Pinseln oder Zeichenfedern und Schablonen gearbeitet werden muß, worunter oft die Genauigkeit leidet.A measurement specification for insulation resistance is laid down in the standard DIN IEC 167 "Test methods for electrical insulating materials", Beuth-Verlag, Berlin 1993. Among other things, this specifies lines of conductive paint, 1 mm wide, (10 +/- 0.5) mm apart, (100 +/- 1 mm) long, for the measuring electrodes. These conductive lines are often used in practice because they are easy to apply. However, they have the disadvantage that they are usually made by hand, using brushes or drawing pens and stencils, which often means that accuracy suffers.
Das Ziel der erfindungsgemäßen Vorrichtung ist es, diesen Mangel zu beheben.The aim of the device according to the invention is to remedy this deficiency.
Der Erfindung liegt die Aufgabe zugrunde und mit geringem Aufwand den leitenden Strichen analoge Strichelektroden zu realisieren.The invention is based on the task of realizing line electrodes analogous to the conductive lines with little effort.
Die Aufgabe wird erfindungsgemäß gelöst, indem Strichelektroden aus sehr gut leitendem Gummi eingesetzt werden . Eine nähere Beschreibung soll anhand von Fig. 1 gegeben werden. Auf einer gut isolierenden Unterlage 1 werden zwei Streifen 1 mm dicker Folie aus gut leitendem Gummi 2 zusammen mit dünnen Metallstreifen 4 in einen mit Nuten versehenen Isolierkörper 4 gehalten. Die Gummifolie 2 überragt den Isolierkörper 4. Die Metallstreifen 3 sind an einem Ende langer als die Gummifolie 2 und als Kontaktblech 5 rechtwinklig abgewinkelt. Auf dem Kontaktblech ist ein Meßkontakt 6, z.B. als Steckbuchse, angebracht.The object is achieved according to the invention by using line electrodes made of highly conductive rubber. A more detailed description is given with reference to Fig. 1. On a well-insulating base 1, two strips of 1 mm thick foil made of highly conductive rubber 2 are held together with thin metal strips 4 in an insulating body 4 provided with grooves. The rubber foil 2 protrudes over the insulating body 4. The metal strips 3 are longer at one end than the rubber foil 2 and are bent at a right angle as a contact plate 5. A measuring contact 6, e.g. as a plug socket, is attached to the contact plate.
Fig. 2 zeigt den Einsatz der erfindungsgemäßen Meßvorrichtung bei der Messung an einer plattenförmigen Probe 7. Die Probe wird an die herausstehenden Leitgummistreifen 2 angedrückt.Fig. 2 shows the use of the measuring device according to the invention when measuring a plate-shaped sample 7. The sample is pressed against the protruding conductive rubber strips 2.
Ausführungsbeispiel: <■Example: <■
Es wird eine handelsübliche leitende Gummifolie 2 mm dick mit einem spezifischen Widerstand kleiner als 5 mOhm cm eingesetzt. Die zwei Leitgummistreifen sind auf 100 &khgr; 11 mm zugeschnitten. Die Grundplatte 1 und der Isolierkörper werden aus PTFE (Teflon) hergestellt. Der Isolierkörper 4 ist 10 mm hoch, so daß die Leitgummistreifen 2 ihn um 1 mm überragen. In Kontakt zu den Leitgummistreifen 2 stehen Blechstreifen aus Edelstahl 3. Der Kontakt 6 wird durch eine Meßbuchse für Bananenstecker realisiert.A commercially available conductive rubber foil 2 mm thick with a specific resistance of less than 5 mOhm cm is used. The two conductive rubber strips are cut to 100 x 11 mm. The base plate 1 and the insulating body are made of PTFE (Teflon). The insulating body 4 is 10 mm high, so that the conductive rubber strips 2 protrude 1 mm above it. Sheet metal strips made of stainless steel 3 are in contact with the conductive rubber strips 2. The contact 6 is made by a test socket for banana plugs.
