Description

Beschreibung :' "Schlüssel zum Einsetzen von Paßringen in Sicherungselencnte (insbesondere für das NDZ System"..) Um eine Verwechslung von Schmelzsicherungen verschiedener Ampere- Stärken in Sicherungselementen zu vermeiden, werden in die Elemente PaBringc-eingesetzt. Zu diese Zweck, sind noch keine Werkzeuge vorhanden. Nach Abb. 1 und 2 soll ein Schlüssel zum Einsetzen von Paßringen zur Anmeldung koBmien. Abb. 1 zeigt einen verstellbaren Schlüssel. Da die Paßringe, welche sehr dünnwandig sind und vielfach aus Porzellan bestehen leieht brechen, wurde das Teil, Konus a aus Go-mi oder Preßstoff herge- stellt. Der Konus a ist gerieft und greift in die Bohrung des Paß- ringes. Durch die Riefen des Konuses a kann der Paßring gedreht werden und so im Gewinde des Sicherungselcmentes ein-ind aus- geschraubt werden. Der Konus- a sitzt auf einer Hülse b und wird mittels einer Schraube d, in den G-riffteil o festgehalten. Abb. 1 zeigt den Konus a für einen Paßring 6 Amp. ausgebildet. Soll nun ein 10 Amp. Paßring eingesetzt werden, dessen Bohrung nun ca. 25 mm grosser ist, so wird das G-riffteil c nach rechts gedreht, die Schralibe d wird dadurch angezogen und der Konus a- zusammc-ngedrückt. Dies hat zur Folge, dass dsr Kenus a in seinen Durchmesser grösser wird und somit für einen Paßring von 10 Amp. verwendbar ist. Für Paßring 15 u. 20 Amp. wird lediglich ein ent- sprechend grösserer Konus a verwendet. Abb. 2 zeigt einen Sehlu. ssel e, welcher ans einem Metallkreuz ? besteht, welches in Weichgummi g eingebettet ist. Die Eonuse k sind jeweils gerieftunddenBohrungen der Päßringe angepasst. Description :' "Key for inserting fitting rings in security elements (especially for the NDZ system "..) To avoid mixing up fuses of different amperes Avoid strengths in securing elements are in the elements PaBringc-used. There are no tools for this purpose available. According to Fig. 1 and 2, a key should be used for inserting fitting rings to register. Fig. 1 shows an adjustable key. Since the fitting rings, which are very thin-walled and often made of porcelain break, the part, cone a, was made from Go-mi or molded represents. The cone a is grooved and engages in the bore of the fitting ringes. The fitting ring can be rotated through the grooves of the cone a and so in-and-out in the thread of the securing element be screwed. The cone a sits on a sleeve b and is by means of a screw d, held in the grip part o. Fig. 1 shows the cone a for a fitting ring 6 Amp. Designed. If a 10 Amp. Fitting ring is to be used, its hole is now approx. 25 mm larger, the grip part c is to the right rotated, the pulley d is tightened and the cone a- compressed. As a result, dsr Kenus a in his Diameter becomes larger and therefore for a fitting ring of 10 Amp. is usable. For the fitting ring 15 and 20 amp. speaking larger cone a used. Fig. 2 shows a Sehlu. ssel e, which one on a metal cross? consists, which is embedded in soft rubber g. The Eonuse k are each grooved and matched to the bores of the fitting rings.
