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 15.1 shows a basic illustration of the components of the contact protection device shown. It is the back of a socket insert 1 (C disc) one Earthing contact socket can be recognized, with a lower part on the back protecting against accidental contact 2 is formed - preferably integrally formed. Further The main components of the contact protection device are a rotary slide 8 and a Touch 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 used to fasten the base) central pin 3 with locking connection 4, which in a corresponding Bore 16 of the contact protection cover 15 engages, either through the snap connection (snap connection) itself or by means of additional suitable Fastening means (for example a screwable on a thread of the pin 2 Nut) a form-fitting connection between the lower part 2 and touch protection cover 15 is carried out. The one in the interior between the contact protection lower part 2 and touch protection cover 15 inserted rotary valve 8 is plugged with its central bore 9 onto the pin 3 and 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 the engagement of spring arms 12, 13 of the rotary valve 8. These spring arms 12, 13 are on the Main body of the rotary valve, d. H. molded on side arms 10, 11 of the rotary valve 8, these side arms 10, 11 a cover when closed of plug openings (see number 7 in Fig. 3). The guideways of the Guide rails 5, 6 lead to the build-up of spring forces in the spring arms 12, 13 during the rotation of the rotary valve 8, these spring forces after removal the plug pins from the socket insert automatically reset 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 two-component injection molded part (Two-component injection molding). When configured as a 2K injection molded part the hard component (formation of the side arms), for example through 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 there are further plug openings 17 in the contact protection cover to recognize which the insertion of plug pins into the base when open Allow the 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.2 is a view of the contact protection device in the closed position shown (with the contact protection cover removed). The two spring arms 12, 13 engage over the initial areas of the guide rails 5, 6 of the lower part of the contact protection 2 and press against these guide rails with a relatively low spring force. The connector openings (see number 7 in Fig. 3) are through the two side arms 10, 11 of the rotary valve 8 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 11, 12 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 engagement troughs designed as inclined planes for the Pins on a connector. If both connector pins are inserted into the connector openings at the same time (see number 7 in Fig. 3) of the socket insert 1, is against the spring force of the spring arms 12, 13 causes the rotary slide 8 to rotate, which leads to the opening of the contact protection device. This increases - conditionally due to the specially designed guidance of the spring arms 11, 12 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 rotary movement of the rotary valve 8 to reduce effective friction are the tips of both spring arms 12, 13 with cams 14 provided, 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.3 shows a view of the contact protection device when the position is open (with the protective cover removed). The side arms 10, 11 of the Rotary slide 8 are at an angle of, for example, 40 ° - 45 ° with respect to that in Fig. 2 rotated closed position, whereby the connector openings 7th be fully opened so that the connector pins are 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 Course of the guide rails 5, 6, the contact protection lower part 2 - enlarged, d. H. the spring arms 12, 13 are in the tensioned state. After pulling out the plug rotates the rotary valve 8 - due to the built and spring force of the spring arms 12, 13 relaxing during the rotary movement automatically returns 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 troughs in the connector openings when the rotary valve is loaded on one side intervene and lock there. Just put a pin in one of the two connector openings 7 inserted, the rotary slide 8 tilts or tilts over several cams 14 ', whereby one of these stepped edges into the plug opening of the contact protection lower part 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.In deviation from the above explanations, it is of course also possible to provide the rotary valve only with a single spring arm which runs along a single guide rail of the contact protection lower part slides.
