Handelsübliche Steckdosen mit erhöhtem Berührungsschutz entsprechen der E DIN VDE 0624-1, wobei der erhöhte Berührungsschutz durch Verwendung eines Schutzschiebers verwirklicht wird. Dieser Schutzschieber schirmt automatisch die spannungsführenden Kontakte der Steckdose ab, sobald der Stecker aus der Steckdose herausgezogen wird. Der Berührungsschutz ist so beschaffen, daß er nicht in einfacher Art und Weise durch Einführen von anderen Gegenständen als Steckern in die Steckdose umgangen werden kann. Beim Einführen eines geeigneten Steckers wird der Berührungsschutz über eine "schiefe Ebene" geöffnet und die Steckerstifte kommen ordnungsgemäß mit den spannungsführenden Kontakten der Steckdose in Berührung. Beim Herausziehen des Steckers drückt eine Rückstellfeder den Berührungsschutz zurück in seine die Steckeröffnungen verschließende, schützende Position. Commercially available sockets with increased contact protection correspond to E DIN VDE 0624-1, whereby the increased contact protection by using a protective slide is realized. This safety gate automatically shields the live ones Disconnect the contacts from the socket as soon as the plug is removed from the socket is pulled out. The contact protection is such that it is not easier Way by inserting items other than plugs into the socket can be bypassed. When inserting a suitable plug, the contact protection opened over a "sloping plane" and the pins come properly with the live contacts of the socket in touch. When pulling out the plug, a return spring pushes the contact protection back into its protective openings closing the plug openings.

In Fig. 1 ist eine prinzipielle Darstellung der Komponenten der Berührungsschutzvorrichtung
dargestellt. Es ist die Rückseite eines Steckdoseneinsatzes 1 (C-Scheibe) einer
Schutzkontakt-Steckdose zu erkennen, wobei an dieser Rückseite ein Berührungsschutz-Unterteil
2 ausgebildet - vorzugsweise einstückig angeformt - ist. Weitere
Hauptkomponenten der Berührungsschutzvorrichtung sind ein Drehschieber 8 und eine
Berührungsschutz-Abdeckung 15.In Fig. 1 is a schematic representation of the components of the contact protection device
shown. It is the back of a socket insert 1 (C-disc) one
Earthing contact socket to recognize, with at this back a contact protection
Das Berührungsschutz-Unterteil 2 weist einen (auch zur Befestigung des Sockels dienenden)
zentralen Zapfen 3 mit Rastverbindung 4 auf, welcher in eine korrespondierende
Bohrung 16 der Berührungsschutz-Abdeckung 15 eingreift, wobei entweder
durch die Rastverbindung (Schnappverbindung) selbst oder mittels zusätzlicher geeigneter
Befestigungsmittel (beispielsweise eine auf ein Gewinde des Zapfens 2 schraubbare
Mutter) eine formschlüssige Verbindung zwischen Berührungsschutz-Unterteil 2
und Berührungsschutz-Abdeckung 15 erfolgt. Der in den Innenraum zwischen Berührungsschutz-Unterteil
2 und Berührungsschutz-Abdeckung 15 eingelegte Drehschieber
8 ist mit seiner zentralen Bohrung 9 auf den Zapfen 3 aufgesteckt und derart zwischen
einer geschlossenen Position und einer geöffneten Position drehbar beweglich.The contact protection
Das Berührungsschutz-Unterteil 2 weist zwei Führungsschienen 5, 6 für den Eingriff
von Federarmen 12, 13 des Drehschiebers 8 auf. Diese Federarme 12, 13 sind an den
Hauptkörper des Drehschiebers, d. h. an Seitenarmen 10, 11 des Drehschiebers 8 angeformt,
wobei diese Seitenarme 10, 11 bei geschlossener Position eine Abdeckung
von Steckeröffnungen (siehe Ziffer 7 in Fig. 3) sicherstellen. Die Führungsbahnen der
Führungsschienen 5, 6 führen zum Aufbau von Federkräften in den Federarmen 12, 13
während der Drehung des Drehschiebers 8, wobei diese Federkräfte nach Entfernung
der Steckerstifte aus dem Steckdoseneinsatz eine selbsttätige Rückstellung des Drehschiebers
8 bewirken.The contact protection
Der Drehschieber 8 ist als Einkomponenten-Spritzgießteil oder als 2K-Spritzgiessteil
(Zwei-Komponenten-Spritzgiessteil) ausgeführt. Bei Ausgestaltung als 2K-Spritzgiessteil
wird die harte Komponente (Bildung der Seitenarme) dabei beispielsweise
durch ein Polycarbonat und die weiche Komponente (Bildung der Federarme) beispielsweise
durch ein Elastomer, thermoplastisches Elastomer oder Silikon gebildet.The
In Fig. 1 sind des weiteren Steckeröffnungen 17 in der Berührungsschutz-Abdeckung
zu erkennen, welche das Einstecken von Steckerstiften in den Sockel bei geöffneter
Position der Berührungsschutzvorrichtung ermöglichen.In Fig. 1 are further
In Fig. 2 ist eine Sicht auf die Berührungsschutzvorrichtung bei geschlossener Position
dargestellt (bei abgenommener Berührungsschutz-Abdeckung). Die beiden Federarme
12, 13 greifen über die Anfangsbereiche der Führungsschienen 5, 6 des Berührungsschutz-Unterteils
2 und drücken mit relativ geringer Federkraft gegen diese Führungsschienen.
Die Steckeröffnungen (siehe Ziffer 7 in Fig. 3) werden durch die beiden Seitenarme
10, 11 des Drehschiebers 8 verschlossen.In Fig. 2 is a view of the contact protection device in the closed position
shown (with removed shock protection cover). The two
Der Drehschieber 8 weist als schiefe Ebenen ausgebildete Eingriffsmulden für die
Steckerstifte eines Steckers auf. Werden gleichzeitig beide Steckerstifte in die Steckeröffnungen
(siehe Ziffer 7 in Fig. 3) des Steckdoseneinsatzes 1 eingesteckt, wird gegen
die Federkraft der Federarme 12, 13 eine Drehbewegung des Drehschiebers 8 bewirkt,
welche zur Öffnung der Berührungsschutzvorrichtung führt. Dabei erhöht sich - bedingt
durch die speziell ausgestaltete Führung der Federarme 12, 13 längs der Führungsschienen
5, 6 - die wirksame Federkraft der Federarme 12, 13 mit fortschreitender
Drehung des Drehschiebers 8. Um die während der Drehbewegung des Drehschiebers
8 wirksame Reibung zu reduzieren, sind die Spitzen beider Federarme 12, 13 mit Nokken
14 versehen, welche reibungsarm längs der Führungsschienen 5, 6 gleiten (siehe
Fig. 1).The
In Fig. 3 ist eine Sicht auf die Berührungsschutzvorrichtung bei geöffneter Position dargestellt
(bei abgenommener Berührungsschutz-Abdeckung). Die Seitenarme 10, 11 des
Drehschiebers 8 sind um einen Winkel von beispielsweise 40° - 45° gegenüber der in
Fig. 2 gezeigten geschlossenen Position verdreht, wodurch die Steckeröffnungen 7
vollständig geöffnet werden, so daß die Steckerstifte in den Sockel des Steckdoseneinsatzes
greifen können. Der Abstand zwischen den Enden der Federarme 12, 13 und
den Seitenarmen 10, 11 hat sich - bedingt durch die spezielle Anordnung und den
Verlauf der Führungsschienen 5, 6, des Berührungsschutz-Unterteils 2 - vergrößert, d.
h. die Federarme 12, 13 befinden sich in gespanntem Zustand. Nach dem Herausziehen
des Steckers dreht sich der Drehschieber 8 - bedingt durch die aufgebaute und
sich während der Drehbewegung entspannende Federkraft der Federarme 12, 13
selbsttätig wieder in die geschlossene Position.In Fig. 3 is a view of the contact protection device is shown in the open position
(with removed protection cover). The
Die Seitenarme 10, 11 des Drehschiebers 8 weisen abgesetzte Kanten an den Rändern
der Eingriffsmulden auf, die bei einseitig belastetem Drehschieber in die Steckeröffnungen
eingreifen und dort verrasten. Wird nur ein Stift in eine der beiden Steckeröffnungen
7 eingesteckt, so wippt bzw. kippt der Drehschieber 8 über mehrere Nocken
14', wodurch eine dieser abgesetzten Kanten in die Steckeröffnung des Berührungsschutz-Unterteils
eingreift. Eine Drehbewegung des Drehschiebers wird somit wirksam
unterbunden und die Steckeröffnungen 7 bleiben verschlossen.The
In Abweichung der vorstehenden Erläuterungen ist es selbstverständlich auch möglich, den Drehschieber lediglich mit einem einzigen Federarm zu versehen, welcher entlang einer einzigen Führungsschiene des Berührungsschutz-Unterteils gleitet.Notwithstanding the above explanations, it is of course also possible to provide the rotary valve with only a single spring arm, which along a single guide rail of the contact protection lower part slides.
