Definitions
- the invention relates to a device plug with fuse according to the preamble of claim 1.
- a connector of this type is known from DE-A-27 07 442.
- the fuse is accessible from the side of the plug that is in use on the outside of the device, in other words from the outside.
- the fuse is usually designed as a fuse holder with a removable fuse insert carrier and a replaceable fuse insert. A great deal of effort is required for production.
- the fuse link serves as the last protection when all other protective circuits in the device fail. If the fuse link has broken, there is a fault in the device. The fault must therefore be corrected before replacing the fuse link. As a rule, the layperson cannot. It is therefore not sensible or even dangerous to leave the replacement of the fuse link to the layperson. Wherever particular risks would be taken, the fuse inside the device was installed in such a way that practically only a specialist can replace the fuse link. Such fuses have to be installed and connected separately, which in turn involves a great deal of effort.
- the object of the invention is to limit the replacement of the fuse link to a person skilled in the art without having to carry out the high outlay required with previous fuses.
- the device connector according to the invention with the fuse is very simple to manufacture, and it can also be easily installed and connected.
- the fuse can advantageously be provided between the outwardly projecting plug pin and the inner connection of the plug.
- miniature fuses such as micro fuses and SMD fuses, can be used with advantage.
- the neutral conductor contact pin 3 and the protective conductor contact pin 4 are each connected directly to the associated connection 10 or 11.
- phase contact pin 5 is electrically conductively connected on the inside by the connecting conductor 9 to the first clip 6 of the fuse holder 2, 6, 7.
- the fuse holder 2, 6, 7 consists of the two clips 6 and 7 and the insulating body 2 which insulates them from one another.
- the fuse link 8 electrically connects the clips 6 and 7 to its fuse element (not shown) conductive.
- the second clip 7 is in turn electrically connected to the connector 12.
- the fuse is located inside the device (not shown) and can only be replaced by a specialist.
- a fuse (analog 2, 6, 7, 8) can also be provided for the neutral conductor.
- the graphic representation was dispensed with due to rational expeditions.
- fuse instead of the fuse (6, 7, 8) shown, another fuse could also be provided, for example miniature fuses or miniature fuse links, such as micro fuse links and SMD fuse links. Fuses or fuse links according to the standards IEC 127 and UL 198.G are suitable, for example.

Description
Die Erfindung betrifft einen Gerätestecker mit Sicherung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device plug with fuse according to the preamble of
Ein Gerätestecker dieser Art ist nach DE-A-27 07 442 bekannt. Die Sicherung ist von der im Gebrauch an der Aussenseite des Gerätes befindlichen Seite des Steckers, mit anderen Worten von aussen zugänglich. Meist ist die Sicherung als ein Sicherungshalter mit einem herausnehmbaren Sicherungseinsatzt-Träger und einem auswechselbaren Sicherungseinsatz ausgebildet. Zur Herstellung ist ein grosser Aufwand erforderlich.A connector of this type is known from DE-A-27 07 442. The fuse is accessible from the side of the plug that is in use on the outside of the device, in other words from the outside. The fuse is usually designed as a fuse holder with a removable fuse insert carrier and a replaceable fuse insert. A great deal of effort is required for production.
Wenn bei einem solchen Gerätestecker mit Sicherung der Sicherungseinsatz den elektrischen Strom unterbrochen hat, kann auch der Laie (Nichtfachmann) den Sicherungseinsatz einfach von aussen, also von der Geräteaussenseite her, auswechseln.If the fuse link in such a device plug with fuse has interrupted the electrical current, even a layperson (non-specialist) can simply replace the fuse link from the outside, i.e. from the outside of the device.
Es ist in zunehmendem Masse möglich, ein Gerät gegen elektrische Fehler, welche ihre Ursache ausserhelb des Gerätes haben, elektronisch, d.h. ohne Sicherungs zu schützen.
Der Sicherungseinsatz dient dann als letzter Schutz, wenn alle übrigen Schutzschaltungen im Gerät ausfallen. Wenn der Sicherungseinsatz unterbrochen hat, liegt also ein Fehler im Gerät vor. Der Fehler muss daher vor dem Ersatz des Sicherungseinsatzes behoben werden. Das kann der Laie in der Regel nicht. Es ist deshalb nicht sinnvoll oder sogar gefährlich das Auswechseln des Sicherungseinsatzes dem Laien zu überlassen. Dort, wo besondere Risiken eingegangen würden, wurde deshalb die Sicherung im inneren des Gerätes so angebracht, dass praktisch nur der Fachmann den Sicherungseinsatz auswechseln kann. Solche Sicherungen müsse getrennt montiert und angeschlossen werden, was wiederum mit eiem grossen Aufwand verbunden ist.It is increasingly possible to protect a device electronically, ie without a fuse, against electrical faults which have their cause outside of the device.
The fuse link serves as the last protection when all other protective circuits in the device fail. If the fuse link has broken, there is a fault in the device. The fault must therefore be corrected before replacing the fuse link. As a rule, the layperson cannot. It is therefore not sensible or even dangerous to leave the replacement of the fuse link to the layperson. Wherever particular risks would be taken, the fuse inside the device was installed in such a way that practically only a specialist can replace the fuse link. Such fuses have to be installed and connected separately, which in turn involves a great deal of effort.
Der Erfindung liegt die Aufgabe zugrunde, das Auswechseln des Sicherungseinsatzes auf den Fachmann zu beschränken, ohne den bei den bisherigen Sicherungen erforderlichen hohen Aufwand zu betreiben.The object of the invention is to limit the replacement of the fuse link to a person skilled in the art without having to carry out the high outlay required with previous fuses.
Zur Lösung der Erfindungsaufgabe wird vorgeschlagen, die Sicherung auf der dem Geräteinneren zugewandten Seite des Gerätesteckers vorzusehen.To solve the problem of the invention, it is proposed to provide the fuse on the side of the device connector facing the interior of the device.
Wie bei einer bekannten, als separates Bauteil, separat im Geräte-Inneren montierten und separat angeschlossenen Sicherung, ist auch bei der Erfindung das Auswechsen des Sicherungseinsatzes nur von innen bei geöffnetem Gerät dem Fachmann vorbehalten. Es entfällt aber der Aufwand eines separaten Bauteils, das separat montiert und angeschlossen werden muss. Man kann zudem sehr einfache Sicherungshalter verwenden, weil sie ja im Inneren des Gerätes vor Zugriff durch Laien geschützt sind, was auch gegenüber den bisherigen Gerätesteckern mit Sicherung sehr aufwandsparend ist. Man braucht, wegen der geschützten Lage der Sicherung im Geräteinneren weder Berührungsschutz noch besondere Abdichtungen des Sicherungshalters vorzusehen.As in the case of a known fuse, which is installed as a separate component and is separately connected in the interior of the device and is connected separately, in the case of the invention the replacement of the fuse link is only reserved for the person skilled in the art from the inside when the device is open. However, there is no need for a separate component that has to be installed and connected separately. You can also use very simple fuse holders because they are protected inside the device against access by laypersons, which is also very cost-effective compared to previous device plugs with a fuse. You need, because of the protected location of the fuse in the Do not provide protection against accidental contact or special seals on the fuse holder.
Vorteilhafterweise kann man aber mit einem einfachen inneren Deckel die Stromführenden Teile auch gegen innen abdecken.Advantageously, you can also cover the current-carrying parts against the inside with a simple inner cover.
Die Herstellung des erfindungsgemässen Gerätesteckers mit Sicherung ist sehr einfach, und er lässt sich auch einfach montieren und anschliessen.The device connector according to the invention with the fuse is very simple to manufacture, and it can also be easily installed and connected.
Vorzugsweise ist nur ein Isolierteil vorhanden, das die Steckerteile und die Sicherung aufnimmt.There is preferably only one insulating part which receives the plug parts and the fuse.
Vorteilhaft kann man die Sicherung zwischen dem nach aussen ragenden Steckstift und dem inneren Anschluss des Steckers vorsehen. Dazu kann man beispielsweise einen einfachen Klips-Sicherungshalter mit einem Sicherungseinsatz vorsehen. Selbst Kleinstsicherunge, wie Mikrosicherungen und SMD-Sicherungen, sind mit Vorteil verwendbar.The fuse can advantageously be provided between the outwardly projecting plug pin and the inner connection of the plug. For example, you can provide a simple clip fuse holder with a fuse link. Even miniature fuses, such as micro fuses and SMD fuses, can be used with advantage.

So befindet sich die Sicherung im Inneren des (nicht dargestellten) Geräts und kann nur durch den Fachmann gewechselt werden.The fuse is located inside the device (not shown) and can only be replaced by a specialist.
Auch für den Nulleiter kann eine Sicherung (analog 2, 6, 7, 8) vorgesehen sein. Auf die zeichnerische Darstellung wurde jedoch aus rationellen Erwegungen verzichtet.A fuse (
Anstelle der gezeichneten Sicherung (6, 7, 8) könnte auch eine andere Sicherung vorgesehen sein, beispielsweise Kleinstsicherungen bzw.
