Description
Für die tägliche Arbeit des Elektroinstallateurs, Autoelektrikers, Radio- und Hochfrequenztechnikers usw. sind als Werkzeug der Schraubenzieher und Gl immlampenspannungsprüfer bekannt. Aufgabe der Erfindung ist es, ein praktisches Spezialwerkzeug vorzuschlagen, das die gleichzeitige Verwendung als Schraubenzieher und als Spannungsprüfer zuläßt. For the daily work of the electrician, car electrician, Radio and radio frequency technician etc are as a tool the screwdriver and Gl imm lamp voltage tester known. The object of the invention is to provide a practical Special tool to propose the simultaneous use as a screwdriver and as a voltage tester.
Erfindungsgemäß werden zur Lösung dieser Aufgabe Schraubenzieher und Glimmlampenspannungsprüfer zu einem Werkzeug vereinigt. According to the invention, screwdrivers are used to solve this problem and glow lamp voltage tester combined into one tool.
Der erfindungsmäßige Schutz-Prüf-Schraubenzieher wird an Hand der Abbildung näher erläutert. The inventive protection test screwdriver is based on the Figure explained in more detail.
Der Schraubenzieher besteht aus dem Stahlschaft 1 und dem durchsichtigen, isolierenden Kunststoffgriff 2, der sich als Isolierüberzug eine beträchtliche Länge über dem Schaft I erstreckt. Der Kunststoffgriff 2 besitzt eine Längsbohrung, in der sich ein NViderstand 3 befindet, der sich mit seinem einen Ende leitend gegen den Schaft I und seinem anderen Ende leitend gegen einen Pol einer anschließend angeordneten Glimmlampe 4 abstützt. Als Abschluß der Längsbohrung dient eine Metallmadenschraube 5, die die leitende Verbindung mit dem,anderen Pol der Glimmlampe 4 herstellt und den Kontaktdruck zwischen Schaft, Widerstand und Glimmlampe gewährleistet. gerührt der blanke Teil des Schraubenzieherschaftes eine spannungführende Leitung und die Hand die Madenschraube, so leuchtet die Glimmlampe auf.The screwdriver consists of the steel shaft 1 and the transparent, insulating plastic handle 2, which can be used as an insulating cover for a considerable length extends over the shaft I. The plastic handle 2 has a longitudinal bore in which is a N resistor 3, one end of which is conductive to the shaft I and its other end conductively against a pole of a subsequent arranged glow lamp 4 is supported. A metal grub screw serves as the end of the longitudinal bore 5, which establishes the conductive connection with the other pole of the glow lamp 4 and ensures the contact pressure between the shaft, resistor and glow lamp. touched the bare part of the screwdriver shaft is a live wire and the Hand the grub screw, the glow lamp lights up.
Der erfindungsmäßige Schutz-Prüf-Schraubenzieher warnt den Arbeitenden, wenn Spannung in der Leitung ist, er dient zur Feststellung der Polarität der Spannung und ist ein handliches und praktisches Werkzeug bei kombinierter Verwendung als Prüfgerät unfl Schraubenzieher. The inventive protection test screwdriver warns the worker, if there is voltage in the line, it is used to determine the polarity of the voltage and is a handy and practical tool when used in combination as a Tester and screwdriver.
