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 lower part 2 formed - preferably integrally formed - is. Further Main components of the contact protection device are a rotary valve 8 and a Contact protection cover 15.

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 lower part 2 has a (also serving to attach the base) central pin 3 with locking connection 4, which in a corresponding Bore 16 of the contact protection cover 15 engages, either by the snap connection (snap connection) itself or by means of additional suitable Fastening means (for example, a screwed onto a thread of the pin 2 Nut) a positive connection between contact protection lower part. 2 and contact protection cover 15 takes place. The in the interior between contact protection lower part 2 and contact protection cover 15 inserted rotary valve 8 is plugged with its central bore 9 on the pin 3 and so between a closed position and an open position rotatably movable.

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 lower part 2 has two guide rails 5, 6 for engagement of spring arms 12, 13 of the rotary valve 8. These spring arms 12, 13 are connected to the Main body of the rotary valve, d. H. formed on side arms 10, 11 of the rotary valve 8, these side arms 10, 11 in the closed position, a cover from plug openings (see paragraph 7 in Fig. 3). The guideways of Guide rails 5, 6 lead to the construction of spring forces in the spring arms 12, 13 during rotation of the rotary valve 8, these spring forces after removal the plug pins from the socket insert an automatic reset of the rotary valve 8 effect.

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 rotary valve 8 is as a one-component injection molded part or as a 2K injection molded part (Two-component injection molding) executed. In design as 2K injection molded part For example, the hard component (formation of the side arms) becomes by a polycarbonate and the soft component (formation of the spring arms), for example formed by an elastomer, thermoplastic elastomer or silicone.

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 plug openings 17 in the contact protection cover to recognize which the insertion of pins into the socket when open Allow position of the contact protection device.

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 spring arms 12, 13 engage over the initial areas of the guide rails 5, 6 of the contact protection lower part 2 and press with relatively little spring force against these guide rails. The plug openings (see paragraph 7 in Fig. 3) are by the two side arms 10, 11 of the rotary valve 8 is closed.

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 rotary valve 8 has trained as inclined planes engagement recesses for Plug pins of a plug on. At the same time both pins in the plug openings (see paragraph 7 in Fig. 3) of the socket insert 1 inserted, is against the spring force of the spring arms 12, 13 causes a rotary movement of the rotary valve 8, which leads to the opening of the contact protection device. This increases - conditionally by the specially designed guide the spring arms 12, 13 along the guide rails 5, 6 - the effective spring force of the spring arms 12, 13 with progressive Rotation of the rotary valve 8. To the during the rotation of the rotary valve To reduce effective friction, the tips of both spring arms 12, 13 with cams 14, which slide along the guide rails 5, 6 with low friction (see Fig. 1).

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 side arms 10, 11 of Rotary valve 8 are at an angle of for example 40 ° - 45 ° relative to the in 2 shown rotated closed position, whereby the plug openings. 7 be fully opened so that the pins in the socket of the socket insert can grab. The distance between the ends of the spring arms 12, 13 and The side arms 10, 11 has - due to the special arrangement and the Course of the guide rails 5, 6, the contact protection lower part 2 - enlarged, d. H. the spring arms 12, 13 are in a stretched state. After pulling out the plug rotates the rotary valve 8 - due to the built and during the rotational movement relaxing spring force of the spring arms 12, 13 automatically back to the closed position.

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 side arms 10, 11 of the rotary valve 8 have offset edges at the edges the engagement recesses, which in one-sided loaded rotary valve in the plug openings intervene and lock there. Will only one pin in one of the two plug openings 7 inserted, so the rotary valve 8 rocks or tilts over several cams 14 ', whereby one of these stepped edges in the plug opening of the contact protection base intervenes. A rotary movement of the rotary valve is thus effective prevented and the plug openings 7 remain closed.

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.
