Description
Die Erfindung betrifft einen elektrischen Sperrstöpsel, der nur nach Verletzung einer Siegelmarke oder Plombe wieder herausgenommen werden kann. Sperrstöpsel oder Blindstöpsel zur Außerbetriebsetzung von Leitungen sind zwar an sich bekannt, doch unterscheidet sich der Gegenstand nach der Erfindung von den bekannten Vorrichtungen dieser Art dadurch, daß nach Einsetzen desThe invention relates to an electrical locking plug that only after injury to a Seal mark or lead seal can be removed again. Stopping plug or dummy plug for putting out of service Lines are known per se, but the subject differs according to the Invention of the known devices of this type in that after the onset of the
ίο Sperrstöpsels eine Plombe oder ein Siegel angebracht werden kann, so daß die Herausnahme des Stöpsels nur möglich ist, wenn diese Plombe oder Siegelmarken entfernt werden. Der Sperrstöpsel wird in die zu sperrende Leitung an geeigneter Stelle, z. B. am Sicherungselement, eingesetzt und verhindert dadurch beispielsweise den Weiterbezug von elektrischem Strom. In der Zeichnung sind zwei Ausführungsbeispiele dargestellt, und zwar zeigtίο the locking plug a lead seal or a seal can be attached so that the plug can only be removed if these seals or seals must be removed. The blocking plug is inserted into the line to be blocked at a suitable point, e.g. B. on the fuse element, thus preventing, for example, the continued use of electricity. In the drawing two embodiments are shown, namely shows

a5 fernt wird. Der Körper a, der aus Isolierstoff bestehen kann, hat einen Fuß c, welcher ein zu tiefes Einschrauben verhindert. Im Körper α ist eine öffnung b eingelassen, um mit Hilfe von geeigneten Werkzeugen ein Festschrauben zu ermöglichen. Diese Öffnung b kann durch eine Plombe oder Siegelmarke verschlossen werden. a 5 is removed. The body a, which can be made of insulating material, has a foot c, which prevents it from being screwed in too deeply. An opening b is made in the body α in order to enable it to be screwed tight with the aid of suitable tools. This opening b can be closed by a lead seal or seal mark.
Fig. 2 zeigt einen Sperrstöpsel, in welchen eine Sperrvorrichtung eingebaut ist, die das Entfernen des Stöpsels nur zuläßt, wenn vorher eine Siegelmarke oder Plombe entfernt wird. Der Körper α kann aus Isolierstoff beFig. 2 shows a locking plug in which a locking device is built, which only allows the plug to be removed if a seal or seal is removed beforehand. The body α can be made of insulating material
