Description

Die Erfindung betrifft einen elektrischen Einbau-Sicherungssockel mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to an electrical built-in fuse base with the features of the preamble of claim 1.

Ein derartiger Sockel ist aus DE-A-29 03 826 bekannt und dient zur Aufnahme von Schmelzsicherungseinsätzen unterschiedlicher Nennstromstärken. Derartige Einsätze weisen Endkontaktkappen auf, die in Einschaltstellung beidseitig von im Bereich der Gehäuseseitenwandungen liegenden Gegenkontakten beaufschlagt werden. Diese Gegenkontakte sing entweder gehäusefest angeordnet oder -insbesondere bei Sicherungssockeln, die für hohe Nennstromstärke ausgelegt sind, zusammen mit dem Innenteil verschwenkbar. Sollen in derartigen Sicherungssockeln Sicherungseinsätze verwendet werden, deren Durchmesser relativ groß ist, so eröffnet sich die Möglichkeit, in den entsprechend groß querschnittsdimensionierten Einsteckschacht des schwenkbaren Innenteils unsachgemäß in grobfahrlässiger Weise einzugreifen und gegebenenfalls das schwenkbare Innenteil in Einschaltstellung zu verbringen, so daß die im Bereich der Schachtöffnung liegenden Gegenkontakte spannungsführend werden (dies ist bei geschalteten Gegenkontakten der Fall, die zusammen mit dem Innenteil verschwenkt werden) oder hinter den seitlichen Öffnungen des Innenteils in Einschaltstellung hervortreten (dies ist bei den gehäusefesten Gegenkontakten der Fall). In beiden Fällen besteht die Gefahr, daß die in das Gerät eingreifende Bedienungsperson durch elektrischen Stromschlag gefährdet ist.Such a base is known from DE-A-29 03 826 and serves to accommodate fuse links of different nominal current strengths. Such inserts have end contact caps which, in the switched-on position, are acted upon on both sides by mating contacts located in the area of the housing side walls. These mating contacts are either arranged fixed to the housing or, in particular in the case of fuse bases which are designed for high nominal current, can be pivoted together with the inner part. If fuse links with a relatively large diameter are to be used in such fuse bases, the possibility arises of improperly intervening in the correspondingly large cross-sectional insertion shaft of the swiveling inner part and, where appropriate, of spending the swiveling inner part in the switch-on position, so that the Counter contacts lying in the shaft opening become live (this is the case with switched counter contacts that are pivoted together with the inner part) or emerge behind the side openings of the inner part in the switch-on position (this is the case with counter contacts fixed to the housing). In both cases there is a risk that the operator intervening in the device is endangered by an electric shock.

Der Erfindung liegt die Aufgabe zugrunde, einen Sicherungssockel nach dem Oberbegriff derart auszubilden, daß er bezüglich seines elektrischen Berührungsschutzes verbessert ist.The invention has for its object to design a fuse base according to the preamble such that it is improved in terms of its electrical protection against accidental contact.

Diese Aufgabe ist durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Als Kerngedanke der Erfindung wird es angesehen, einen Berührungsschutz durch Drehverriegelung des schwenkbaren Innenteils vorzunehmen, die ausschließlich durch den in den Schacht des schwenkbaren Innenteils hineinpassenden Halter für die Schmelzsicherungseinsätze aufgehoben werden kann. Es ist somit ein Verschwenken des Innenteils in die Einschalt- und damit gefährliche Stellung nur dann möglich, wenn der vorschriftsmäßige Schmelzsicherungschalter verwendet wird. Insbesondere ist ein Verbringen des schwenkbaren Innenteils in die Einschaltstellung beispielsweise durch einen Schraubenzieher oder einen hineingesteckten Finger nicht möglich. Bei geschalteten, d. h. mit dem Innenteil zusammen verschwenkbaren, Gegenkontakten wird durch die Erfindung vermieden, daß durch die Einschaltschwenkbewegung die Gegenkontakte stromführend werden, bei nicht geschalteten und gehäusefesten Gegenkontakten wird vermieden, daß durch Verbringen des schwenkbaren Innenteils die Gegenkontakte hinter den seitlichen Öffnungen des Innenteils offenliegen und damit berührt werden können.The key idea of the invention is to provide protection against accidental contact by means of a rotary lock on the pivotable inner part, which can only be lifted by the holder for the fuse links which fits into the shaft of the pivotable inner part. It is therefore only possible to pivot the inner part into the switch-on and thus dangerous position if the correct fuse switch is used. In particular, it is not possible to move the pivotable inner part into the switched-on position, for example by means of a screwdriver or a finger inserted therein. When switched, d. H. with the inner part pivotable, counter-contacts is avoided by the invention that the counter-contacts are energized by the switch-on pivoting movement, with non-switched and housing-fixed counter-contacts it is avoided that the counter-contacts are exposed behind the lateral openings of the inner part and brought into contact with them by moving the pivotable inner part can.

Durch die Merkmale des Anspruches 2 wird der Tatsache Rechnung getragen, daß die in Frage stehenden Schalter möglichst schmal ausgebildet werden sollen, somit wird ein Gehäusebereich ausgenutzt, der ohnehin bei den meisten Schalterausführungen ungenutzt zur Verfügung steht. Darüber hinaus ist von Vorteil, daß durch die Federbeaufschlagung des Halters entgegen der Einschubrichtung der Halter beim Verschwenken in die Einschaltstellung gegen ihn im Bereich des Griffes zumindest teilweise übergreifende Gehäusevorsprünge gedrückt wird, womit eine zusätzliche Hemmwirkung des Schalters in Einschaltstellung erzielt ist. Zudem wird ein Einschalt-Schnappeffekt dadurch erzielt, daß der Halter vor der Einschaltschwenkbewegung zunächst etwas gegen die Federkraft der Rastvorrichtung in den Schacht hineingedrückt werden muß, wonach schlagartig durch Entriegelung die Einschaltschwenkbewegung erfolgen kann.The features of claim 2 take into account the fact that the switches in question are to be made as narrow as possible, thus utilizing a housing area which is available unused in most switch designs anyway. In addition, it is advantageous that, due to the spring loading of the holder against the insertion direction of the holder when pivoting into the switch-on position, housing protrusions are at least partially pressed against it in the region of the handle, thus achieving an additional inhibitory effect of the switch in the switch-on position. In addition, a switch-on snap effect is achieved in that the holder must first be pressed somewhat against the spring force of the latching device into the shaft before the switch-in pivoting movement, after which the switch-in pivoting movement can take place suddenly by unlocking.

Mit Anspruch 3 wird ein vorteilhafter Doppeleffekt des als Zapfen ausgebildeten Vorsprunges erzielt, da es möglich ist, über die außermittige Anordnung des Zapfens die Einschaltschwenkbewegung tatsächlich nur dann freizugeben, wenn der richtige Halter in den Sicherungssockel entsprechender Nennstromstärke eingeführt ist.With claim 3, an advantageous double effect of the projection designed as a pin is achieved, since it is possible to actually release the switch-on pivoting movement via the eccentric arrangement of the pin only when the correct holder is inserted into the fuse base of corresponding nominal current.

Eine Selbstzentrierung des Zapfens in der Entriegelungsöffnung wird durch Anspruch 4 gelehrt.A self-centering of the pin in the unlocking opening is taught by claim 4.

Durch die Merkmale des Anspruches 5 wird dem Zapfen eine vorteilhafte Doppelfunktion zugewiesen, da er nicht nur als die Verrastung aufhebendes Organ dient, sondern über elektrische Schaltmittel, nämlich Ein- Ausschaltkontakte, beispielsweise eine elektrische Betriebszustandsanzeigevorrichtung ein- und ausschalten kann, die im Sicherungssockel vorgesehen sein soll.Due to the features of claim 5, the pin is assigned an advantageous double function, since it not only serves as an organ that disengages the latching, but can also switch on and off an electrical operating state display device, for example an electrical operating state display device, which is provided in the fuse base, via electrical switching means should.

Weiterhin vorteilhaft ist der Zapfen dann, wenn er durch unterschiedliche Querschnittsform oder Zapfenlänge oder -stärke und/oder unterschiedliche außerzentrische Anordnung als Unverwechselbarkeitsorgan für die Nennstromgröße zwischen Innenteil und Halterung dient. Dadurch wird es unmöglich, einen Halter zu geringer Nennstromstärke in den Sockel einzuführen, geschweige denn das Innenteil des Sockels in Einschaltstellung zu verbringen.The pin is furthermore advantageous if it serves as an unmistakable organ for the nominal current size between the inner part and the holder due to different cross-sectional shape or pin length or thickness and / or different off-center arrangement. This makes it impossible to insert a holder with a low nominal current into the base, let alone to put the inner part of the base in the switch-on position.

Wird der Sockel mit weiteren im wesentlichen identischen Sockeln zu einem mehrpoligen Einbau-Sicherungssockel zusammengesetzt und die Drehbewegung der Sockelinnenteile durch Drehkopplungsstüke aneinander gekoppelt, so wirkt die Rastvorrichtung nur eines Einzelsockels in besonders vorteilhafter Weise auch auf die neben diesem liegenden Sockel, wodurch es beispielsweise unmöglich ist, auch nur einen Pol eines mehrpoligen Sicherungssockels einzuschalten, wenn nicht alle Halter des Sockels in vorschriftsmäßiger, nennstromangepaßter Weise eingesetzt sind.If the base is assembled with other essentially identical bases to form a multi-pole built-in fuse base and the rotary movement of the inner base parts is coupled to one another by means of rotary coupling pieces, then the latching device of only one base acts in a particularly advantageous manner on the base located next to it, which makes it impossible, for example to switch on even one pole of a multi-pole fuse socket if not all holders of the socket are used in accordance with the regulations in accordance with the nominal current.

Die Erfindung ist anhand eines Ausführungsbeispieles in den Figuren der Zeichnung näher erläutert. Es zeigen :

  • Fig. 1 eine Innenansicht eines Einbausicherungssockels in verriegelter Ausschaltstellung,
  • Fig. 2 eine Ansicht gemäß Fig. 1 in entriegelter Einschaltstellung,
  • Fig. 3 eine Innenansicht der die Rastvorrichtung tragenden Gehäusehalbschale,
  • Fig. 4 eine Seitenansicht der in den Sockel einführbaren Halterung.
The invention is explained in more detail using an exemplary embodiment in the figures of the drawing. Show it :
  • 1 is an interior view of a built-in fuse base in the locked off position,
  • 2 is a view according to FIG. 1 in the unlocked switch-on position,
  • 3 is an interior view of the housing half-shell carrying the latching device,
  • Fig. 4 is a side view of the holder insertable into the base.

Der Einbausicherungssockel 1 für Schmelzsicherungseinsätze mit Endkontaktkappen besteht im wesentlichen aus einem Sockelgehäuse 2 und einem in diesem verschwenkbaren Innenteil 3, in das der Schmelzsicherungseinsatz mittels einer Halterung 4 einsetzbar ist, die an ihrem gehäuseäußeren Ende einen Betätigungsgriff 5 trägt. Die Halterung 4 ist beidseitig derart offen ausgebildet, daß die Endkontaktkappen durch innerhalb des Sockelgehäuses 2 vorgesehene Gegenkontakte 6, 7 beaufschlagt werden können. Dabei sind die Gegenkontakte 6 gehäusefest angeordnet, die Gegenkontakte 7 hingegen am schwenkbaren Innenteil befestigt, wobei durch Einschaltkontakte 8 die Gegenkontakte 7 erst dann spannungsführend werden, wenn das schwenkbare Innenteil 3 in die in Figur 2 gezeigte Einschaltstellung verbracht ist. (Es ist ebenso möglich, innerhalb des Sockelgehäuses ausschließlich bewegliche oder ausschließlich gehäusefeste Gegenkontakte vorzusehen).The built-in fuse base 1 for fuse links with end contact caps essentially consists of a base housing 2 and an inner part 3 which can be pivoted therein, into which the fuse link can be inserted by means of a holder 4 which carries an actuating handle 5 at its outer end. The holder 4 is open on both sides in such a way that the end contact caps can be acted upon by counter contacts 6, 7 provided within the base housing 2. The mating contacts 6 are arranged fixed to the housing, the mating contacts 7, on the other hand, are fastened to the swiveling inner part, with the mating contacts 7 only becoming live through the switching contacts 8 when the swiveling inner part 3 has been brought into the switch-on position shown in FIG. (It is also possible to provide only movable or fixed counter contacts within the base housing).

Im Bereich des Gehäusebodens 9 des Sockelgehäuses 2 ist eine mit dem schwenkbaren Innenteil 3 zusammenwirkende Rastvorrichtung 10 vorgesehen, deren Rastteil eine gegen das schwenkbare Innenteil 3 federbelastete Rastnase 11 ist, die bei herausgezogener Halterung 4 in eine Ausnehmung 12 des Innenteils 3 in Ausschaltstellung eingreift. Wird die Halterung 4 vollständig in das schwenkbare Innenteil 3 eingeschoben, so wird die Rastnase 11 dadurch außer Eingriff mit dem schwenkbaren Innenteil gebracht, daß ein am dem Betätigungsgriff 5 abgewandten Ende 13 angeordneter Vorsprung (Zapfen 14) eine Durchtrittsöffnung 15 im Boden 16 des Einführungsschachtes 17 durchgreift und gegen Federrichtung 18 die Rastnase 11 aus der Gegenraste (Ausnehmung 12) des schwenkbaren Innenteils aushebt (siehe dazu gestrichelte Darstellung der Rastvorrichtung 10 in Fig. 1).In the area of the housing base 9 of the base housing 2, a latching device 10 which interacts with the pivotable inner part 3 is provided, the latching part of which is a latching nose 11 which is spring-loaded against the pivotable inner part 3 and which engages in a cutout 12 of the inner part 3 in the switched-off position when the holder 4 is pulled out. If the holder 4 is pushed completely into the pivotable inner part 3, the latching lug 11 is brought out of engagement with the pivotable inner part in that a projection (pin 14) arranged on the end 13 remote from the actuating handle 5 has a passage opening 15 in the bottom 16 of the insertion shaft 17 reaches through and lifts the locking lug 11 out of the counter-locking (recess 12) of the pivotable inner part against the spring direction 18 (see dashed illustration of the locking device 10 in FIG. 1).

Mit Vorteil ist für den benötigten Raumbedarf und die Federeigenschaften die Rastvorrichtung 10 als etwa parallel zum Gehäuseboden 9 verlaufender, langgestreckter, einseitig eingespannter Federhebel aus federndem Kunststoffmaterial ausgebildet, von dem die Rastnase 11 nach oben absteht. Das Schwenkende 19 der als Federhebel ausgebildeten Rastvorrichtung 10 kann zur Unterstützung der Federkraft durch eine zusätzliche Feder (Schraubenfeder 20) in Richtung des schwenkbaren Innenteils 3 unterstützt sein.For the required space and the spring properties, the latching device 10 is advantageously designed as an elongated spring lever made of resilient plastic material running approximately parallel to the housing base 9 and from which the latching lug 11 projects upwards. The pivoting end 19 of the locking device 10 designed as a spring lever can be supported in the direction of the pivotable inner part 3 to support the spring force by an additional spring (coil spring 20).

Der Zapfen verläuft in Einsteckrichtung 21 der Halterung, ist teilweise konisch ausgeformt und außerzentrisch an der Halterung 4 angeordnet. Ein Entriegeln der Rastvorrichtung 10 ist somit nur durch einen Halter 4 möglich, der einen zu der Durchtrittöffnung 15 passend am Halter angeordneten Zapfen aufweist.The pin runs in the insertion direction 21 of the holder, is partially conical and is arranged eccentrically on the holder 4. Unlocking the locking device 10 is thus only possible by a holder 4 which has a pin arranged on the holder to match the passage opening 15.

Wie insbesondere in Fig. 1 zu sehen ist, können im Bereich der Drehachsen der Innenteile 3 Drehkopplungsstücke 22 kreuzartigen Querschnitts vorgesehen sein, die die Drehbewegung der Innenteile 3 von nebeneinanderliegenden Sockelgehäusen koppeln.As can be seen in particular in FIG. 1, in the region of the axes of rotation of the inner parts 3 rotary coupling pieces 22 can be provided in a cross-shaped cross section, which couple the rotary movement of the inner parts 3 of base housings lying next to one another.

Schließlich sind mit 23 Schaltkontakte bezeichnet, die mit der Rastvorrichtung 10 im Bereich des Gehäusebodens 9 zusammenwirken und zur Ein- Ausschaltung einer nicht näher dargestellten Betriebszustandsanzeigevorrichtung, insbesondere einer elektronischen Blinkschaltung dienen.Finally, 23 are designated as switching contacts, which interact with the latching device 10 in the area of the housing base 9 and are used to switch an operating status display device, not shown in detail, in particular an electronic flashing circuit on and off.
