Description
Prüfvorrichtung für elektrische Apparate. Der Gegenstand vorliegender Erfindung ist eine Prüfvorrichtung für elektrische Apparate, beispielsweise für Telephone u. dgl. Sie hat den Vorzug, daß sie außerordentlich klein ist, daher bequem in der kleinsten Tasche untergebracht werden kann und zu ihrer Verwendung nicht der geringsten anderen Hilfsmittel bedarf.Testing device for electrical apparatus. The subject matter at hand Invention is a test device for electrical apparatus, for example for Telephone and the like. It has the merit of being extremely small, therefore convenient Can be accommodated in the smallest pocket and not to be used the slightest need for other aids.
Die neue Prüfvorrichtung ist auf der Zeichnung in der Abb. i in Ansicht, in der Abb. 2 in einem zur Bildebene der Abb. i parallelen Schnitt durch das Gehäuse und in der Abb.3 in einetiä zu ersterem senkrechten Schnitt dargestellt.The new test device is in the drawing in Fig. I in view, in Fig. 2 in a section through the housing parallel to the plane of Fig. i and shown in Fig.3 in a section perpendicular to the former.
Die Vorrichtung besteht aus zwei Blechplättchen a, b. Beispielsweise ist a ein Aluminiumplättchen und b ein Kupferplättchen, deren Kanten in geringem Abstande voneinander, beispielsweise durch Lötung bei c, c, gehalten werden. Das Ganze ist von einem Gehäuse d aus nicht leitendem Stoff umgeben.. Dieses Gehäuse hat einen Ausschnitt e, durch den der feine Spalt f zwischen den beiden Platten sichtbar und erreichbar wird. An die beiden Platten a und b schließen sich Drähte g, h, mittels welcher die Vorrichtung an den zu prüfenden elektrischen Apparat angeschlossen wird.The device consists of two sheet metal plates a, b. For example, a is an aluminum plate and b is a copper plate, the edges of which are kept at a small distance from one another, for example by soldering at c, c. The whole is surrounded by a housing d made of non-conductive material. This housing has a cutout e through which the fine gap f between the two plates can be seen and reached. Wires g, h, by means of which the device is connected to the electrical apparatus to be tested, are connected to the two plates a and b.
Will man eine solche Prüfung ausführen, so werden, wie schon angedeutet, die beiden Drähte g, h an geeigneten Stellen mit dem zu prüfenden Apparat i (Abb. 2) verbunden, wobei man den mit Speichel angefeuchteten Finger in dem Ausschnitte leicht auf die beiden Platten a, b drückt. In dem Augenblick, in dem hier die Verbindung zwischen diesen hergestellt wird, fließt ein Strom von i # io-' bis i # io-12 Amp. durch die Drähte, und die zu prüfenden Apparate sprechen in irgendeiner Weise an. Der Ausschnitte dient zur Aufnahme des Speichels, ohne daß es bei der Prüfung der Zuhilfenahme des Fingers bedarf.If one wants to carry out such a test, as already indicated, Connect the two wires g, h to suitable points with the apparatus i to be tested (Fig. 2), placing the finger moistened with saliva in the cutout presses lightly on the two plates a, b. At the moment when the connection is here is established between these, a current flows from i # io- 'to i # io-12 Amp. through the wires, and the devices under test respond in some way. The cut-out is used to receive the saliva without it when examining the Use of the finger is required.
