Description

Stromzeiger mit in einem Gehäuse befindlichem Magneten, der frei schwingbar gelagert ist und mit einem Zeiger über einer Skala spielt. Die Erfindung betrifft eine Vorrichtung, um Ströme in Drähten nachzuweisen, und das Wesen der Erfindung besteht darin, eine Vorrichtung zu schaffen, um Kurzschlüsse in dem Stromkreise von Automobilen u. dgl. festzustellen.Current pointer with magnet located in a housing, which can oscillate freely is stored and plays with a pointer over a scale. The invention relates to a device to detect currents in wires and the essence of the invention is to create a device to avoid short circuits in the electrical circuit of automobiles and the like.

Eine Ausführungsform des Erfindungsgegenstandes ist in den Zeichnungen dargestellt Abb. i ist eine Draufsicht der Vorrichtung: Abb. z ist ein Schnitt durch dieselbe, und Abb. 3 -neigt die Vorrichtung in Draufsicht mit einem zweiten Magneten.An embodiment of the subject matter of the invention is shown in the drawings Fig. i is a top view of the device: Fig. z is a section through the same, and Fig. 3 -tilts the device in plan view with a second magnet.

Die Vorrichtung besteht in an sich bekannter Weise aus einem Gehäuse i und einem frei aufgehängten permanenten Magneten a, der auf einem Stift 3 angeordnet ist. Fernerhin ist ein ortsfester permanenter Magnet 4. vorgesehen, und ein nicht magnetischer Zeiger ,5 spielt über einer Skala 6, deren Nullpunkt mit dem Mittelpunkt der Skala zusammenfällt. Die Teile sind so angeordnet, daß der Magnet 4 den Zeiger 5 über dem Nullpunkt hält, solange die Vorrichtung von keinem elektrischen Strom beeinflußt wird. Wird jedoch die Vorrichtung neben einem stromdurchflossenen Draht angeordnet, so wird der Strom den Magneten a zur Ausschwingung bringen, so daß die Nadel 5 auf der Skala die Stromstärke angeben wird. Ist der Strom positiv, so bewegt sich die Nadel 5 in der einen Richtung, und für einen negativenStrom bewegt sie sich in der entgegengesetzten Richtung.The device consists of a housing in a manner known per se i and a freely suspended permanent magnet a, which is arranged on a pin 3 is. Furthermore, a stationary permanent magnet 4. is provided, and one is not magnetic pointer, 5 plays over a scale 6, the zero point with the center the scale coincides. The parts are arranged so that the magnet 4 is the pointer 5 holds above zero as long as the device has no electrical current being affected. However, if the device is next to a current-carrying wire arranged, the current will bring the magnet a to oscillate so that the Needle 5 on the scale will indicate the current strength. If the current is positive, it is moving the needle 5 moves in one direction, and for a negative current it moves going in the opposite direction.

Um die Vorrichtung für Stromkreise von geringer Stärke und hoher Spannung zu verwenden, wird ein zweiter halbkreisförmiger Magnet S angeordnet, der den Magneten .I umgibt und von einem Ring 7 getragen wird, welcher abnehmbar mit dem Gehäuse verbunden ist. Durch den zusätzlichen Magneten wird die magnetische U irkung bei schwachen Strömen verstärkt. Es kann natürlich eine größere Anzahl solcher zusätzlicher Magnete angeordnet werden.To the device for circuits of low strength and high voltage To use a second semicircular magnet S is placed, which is the magnet .I surrounds and is carried by a ring 7 which is detachable with the housing connected is. The magnetic effect is due to the additional magnet weak currents amplified. There can of course be a larger number of such additional ones Magnets are arranged.

Aus Vorstehendem erhellt, daß, wenn die Vorrichtung neben einem Draht angeordnet wird, die \ adel 5 die Nullstellung einnehmen wird, wenn kein Strom deri Draht durchfließt. Bei Stromdurchgang werden jedoch die Nadel 5 und der Magnet z ausschwingen und so das Vorhandensein eines Stromes angeben.From the foregoing it is evident that when the device is next to a wire is arranged, the \ adel 5 will assume the zero position when there is no current deri Wire flows through. When the current passes through, however, the needle 5 and the magnet z decay and thus indicate the presence of a current.
