PATENTAMT,PATENT OFFICE,

\^forliegende Erfindung betrifft einen Sicherungsstöpsel mit mehreren nacheinander benutzbaren Abschmelzdrähten, die vollkommen im Innern des Stöpsels selbst verlagert sind. Der Stöpsel kennzeichnet sich dadurch, daß die den jedesmaligen Stromschluß herbeiführende Schalteinrichtung beweglich außen auf dem Stöpsel angeordnet ist, wodurch eine einfache Handhabung und eine vom Innern\ ^F orliegende invention relates to a fuse plug with a plurality of successively usable Abschmelzdrähten that are completely displaced in the interior of the plug itself. The plug is characterized in that the switching device which brings about the current connection is arranged movably on the outside of the plug, which makes it easy to use and from the inside

ίο des Stöpsels unabhängige Kontaktbildung erzielt wird.ίο the plug achieved independent contact formation will.

Bekanntlich ist es bei derartigen Sicherungsstöpseln notwendig, das Innere des Stöpsels, den oder die Aufnahmeräume für die Abschmelzdrähte, mit Sand bezw. Schmirgel aufzufüllen, damit beim Durchschmelzen nicht durch die im Innern des Stöpsels vorhandene LuftexplosiveErscheinungen auftreten können. Wenn man nun das Schaltorgan im gleichen Räume wie die Drähte anbringt, so wird im Innern des Stöpsels eine Abänderung herbei-. geführt, die möglichst zu vermeiden ist. Auf alle Fälle greift man, wie auch das Schaltorgan gestaltet sein mag, bei einer solchen Anordnung in den zur Aufnahme der Drähte dienenden Teil des Stöpsels irgendwie ein, wodurch die Auffüllung ungünstig betroffen wird.As is known, it is necessary with such fuse plugs, the interior of the Plug, the or the receiving space for the consumable wires, respectively with sand. emery to be filled up so that when it melts through, it does not go through the inside of the stopper Air explosive phenomena can occur. If you now have the switching element in the same Spaces as the wires are attached, so a modification is brought about inside the plug. which should be avoided if possible. In any case, you grasp like the switching element may be designed, with such an arrangement in the part of the plug serving to receive the wires somehow, whereby the padding is adversely affected.

Bringt man nun nach vorliegender Erfindung die Schalteinrichtung außen auf dem Stöpsel, also vollkommen räumlich getrennt von dem Innern des Stöpsels, das die Drähte enthält, mit Sand oder dergl. gefüllt und mit Asbest usw. abgedeckt ist, an, so verändert man im Innern des Sicherungsstöpsels nichts.If you now bring the switching device on the outside of the present invention Plug, so completely spatially separated from the inside of the plug that holds the wires contains, is filled with sand or the like. And covered with asbestos, etc., so changed nothing inside the fuse plug.

Das Umschalten geht in gesonderten Räumen, die mit dem oder den Aufnahmeräumen der Drähte nicht in Verbindung stehen, vor sich. Ein weiterer Vorteil dieser Anordnung ist noch der, daß man ohne weiteres eine Kontrolle über die Kontaktbildung hat. Bei den Stöpseln, bei denen die Kontaktbildung in dem oder den Räumen für die Drähte geschieht, kann man eine solche Kontrolle nur haben, wenn man den Stöpsel öffnet, während, wenn die Bedienung etwa von außen geschieht und man den Stöpsel infolgedessen nicht öffnet, eine Kontrolle überhaupt nicht vorhanden ist.Switching takes place in separate rooms that are connected to the recording room or rooms of the Wires not connected in front of you. Another advantage of this arrangement is nor the fact that one can easily control the formation of contacts. Both Plugs in which the contact is made in the space or spaces for the wires, you can only have such a control if you open the plug, while if the operation is done from the outside and if the stopper is not opened as a result, there is no control at all.

Auf der Zeichnung ist in Fig. 1 im Schnitt und in Fig. 2 in Aufsicht mit abgenommenem Deckel ein Sicherungsstöpsel nach vorliegender Erfindung dargestellt.On the drawing is in Fig. 1 in section and in Fig. 2 in plan view with removed Lid shown a fuse plug according to the present invention.

In dem Sicherungsstöpselgehäuse 1 sind fünf Abschmelzdrähte 2 fest verlagert. Das Stöpselgehäuse besitzt eine mittlere Bohrung, in der sich ein Einsatzstern 3 befindet, der mit Rippen 4 ausgestattet ist, durch welche die Abschmelzdrähte 2 voneinander geschieden sind. Die Abschmelzdrähte 2 stehen mit dem Kontaktstifte 5 in fester leitender Verbindung. Der Stift 5 selbst ist an seinem Bolzenteile 6 mit Rippen 7 ausgestattet, durch die auch dort die Abschmelzdrähte 2 voneinander geschieden werden. In der mittleren Bohrung verlaufen unterhalb der Anspannmutter 8 für den Stift 5 die Abschmelzdrähte in wagerechten, im Gehäusematerial hergestellten Rillen. Aus der mittleren Bohrung treten die Abschmelzdrähte 2 oben heraus undFive consumable wires 2 are permanently displaced in the fuse plug housing 1. That Plug housing has a central bore in which there is an insert star 3, the is equipped with ribs 4 by which the consumable wires 2 are separated from one another are. The consumable wires 2 are in permanent conductive connection with the contact pins 5. The pin 5 itself is equipped with ribs 7 on its bolt parts 6, through which also there the consumable wires 2 are separated from one another. In the middle hole run below the tensioning nut 8 for the pin 5, the consumable wires in horizontal, Grooves made in the housing material. The consumable wires 2 emerge from the middle hole at the top and

Claims

are now through five segment-like lying around the receiving space for the wires Bores 9 led to the contact device, which the conductive connection to establish with the outer contact screw sleeve IO when the switching device is inserted.

In each segment-like incision 9 there is a piece of metal resting against the noses 11, which is equipped with a tab 12 where part II fills the cross-section of FIG. The screw sleeve 10 is with a metal cylinder 13 conductively connected, which with tabs 14 also into the openings 9 intervenes.

On the cylinder 13 and the subsequent cylindrical parts of the screw sleeve 10 is now a ring 15 made of insulating material rotatable and longitudinally. slidably attached. This The ring carries two metal springs 16 and 17 lying on their backs against one another. In FIG. 1 is by means of this contact device current connection between the screw sleeve 10 and the Contact pins 5 made by switching on the consumable wire 2 shown. The springs 16 'and 17 connect the tabs 12 and 14 conductively with one another. The connection of the wires 2 with the contact pieces 11 is made by soldering, and for this purpose the plug housing 1 has lateral Openings 18 which, when the soldering is completed, are expediently closed with plaster of paris. The inside of the stopper is filled with emery or sand, whichever filling is appropriate is covered with asbestos sheets, whereupon, the lid is screwed on.

For the purpose of switching, the fuse plug is in the above embodiment as The whole thing is screwed out of its socket, then you pull it out of insulating material existing ring 15 the springs 16 and 17 from the contact device 12, 14 turns the ring a little and pushes the springs 16 and 17 into the next contact direction 12, 14 a. Then you screw the fuse plug 6 back into the Version inside. The ring 15 is provided with a cylindrical lugs, which when screwed in Fuse plug also still penetrates into the socket. Moving the ring 15 and thus switching is not to be carried out with the plug screwed in.

Instead of, as in the version just described and shown in the drawing, To use two contact pieces 12 and 14, one can also use the clamping spring device use it yourself to conduct electricity. It is then the part 11 on which the wire 2 is soldered, provided with two tabs, and when advancing the ring 15 penetrates Spring device between these two tabs, on the other hand it is in conductive connection with the screw sleeve 10. The operation here is the same as shown above.

Instead of using five consumable wires as shown, the wires can also be in other number be arranged.

These fuse plugs, in which the switching element is on the outside of the plug body be ^ arranged, also show still has the very important advantage that when switching. the plug not under Electricity can stand.

The switchover can also take place via a plug contact device, which is art is operated so that the plug is not removed from the socket; in all cases but the formation of contact takes place in spaces that are connected to the receiving space or spaces for the consumable wires are divorced. Furthermore, the plug does not need to be opened will.

The electrical connection can also be achieved by means of a screw; the Indian Drawing shown plug contact is only with consideration for the convenience of the Circuit has been chosen.

Ρλτεντ-Anspeuch:

Fuse plug with several consumable wires that can be used one after the other, which are arranged inside the fuse plug, characterized in that the current circuit ' causing switching device movably arranged outside on the fuse plug is, for the purpose, a simple handling of the switching device as well as an independent of the interior of the plug To achieve contact formation.
