Die Erfindung betrifft eine elektrische S-shutzkontaktstecküose nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrical S-protective contact socket according to the preamble of claim 1.
Im Gegensatz zu den in herkömmlicher Weise verwendeten Steckdosen üiit Schraubanschluß werden neuerdings überwiegend Steckdosen mit schraubenlosen Steck-Klemm-An-Schlüssen für die elektrischen Stromleiter verwendet.In contrast to the conventionally used sockets with screw connections, sockets with screwless plug-in terminal connections are now predominantly used for the electrical current conductors.
Aus der DE-PS 16 90 436 ist eine derartige elektrische Schutzkontaktsteckdose bekannt, welche für den Anschluß eines Phasenleiters, eines Nulleiters sowie eines Schutzleiters geeignete schraubenlose Leiteranschlußklemmen aufweist. Hierbei ist ein gemeinsames Klemmfederlöseorgan vorgesehen, welches die Klewmfederaufnähme der Leiteranschlußklemmen abdeckt sowie mittels am Klemmfederlöseorgan angebrachter Klemmfederdruckknöpfe, den elektrischen Anschluß sowie die elektrische Trennung der Stromleiter ermöglicht.From DE-PS 16 90 436, such an electrical protective contact socket is known, which has screwless conductor connection terminals suitable for the connection of a phase conductor, a neutral conductor and a protective conductor. A common clamping spring release device is provided here, which covers the clamping spring receptacle of the conductor connection terminals and enables the electrical connection and electrical separation of the current conductors by means of clamping spring push buttons attached to the clamping spring release device.
Aus dem deutschen Gebrauchsmuster DE-GM 88 04 924 ist ferner eine elektrische Schutzkontaktsteckdose mitThe German utility model DE-GM 88 04 924 also discloses an electrical safety socket with
Mp.Nr. 90/558 2 27.04.1990Mp.No. 90/558 2 27.04.1990
scbraubenlosen Leiteranschlußklemmen bekannt, bei welcher als Klemmfederlöseorgan eine Steckdosensockelabf?eckung mit hieran angebrachten Klemmfederlösetasten nebst Drucknocken vorgesehen ist. Hierbei ist das Klemmfederloseorgan über den Steckanschlüssen sowie den .Stecktulpen für den anzuschlief naen Stecker angeordnet. Das Klemmfederlöseorgan besteht im allgemeinen aus Kunststoff und wird meistens mit der Hand ohne spezielles Werkzeug betätigt. Zwar sehen Sicherheitsbestimmungen vor, daß das Lösen und der Anschluß von Stro»iü.eitern im spannungsfreien Zustand erfolgen soll, aber in der Montagepraxis werden diese Vorschriften nur unzureichend eingehalten. In diesem Fall laufe der Elektroinstallateur Gefahr, spannungsführende Teile zu berühren. Da gleichzeitig in der Regel zudem entweder der Schutzkontakterdungsbügel und/oder der metallische Tragrahmen für den Steckdosensockel berührt wird, ist die Gefahr eines elektrischen Unfalls besonders groß. Hier schafft die Erfindung Abhilfe.screwless conductor connection terminals are known, in which a socket base cover with clamping spring release buttons attached to it and pressure cams is provided as a clamping spring release device. The clamping spring release device is arranged above the plug connections and the plug tulips for the plugged-in plug. The clamping spring release device is generally made of plastic and is usually operated by hand without special tools. Safety regulations stipulate that the disconnection and connection of power conductors should take place in a de-energized state, but in assembly practice these regulations are only inadequately observed. In this case, the electrician runs the risk of touching live parts. Since either the protective contact earthing bracket and/or the metal support frame for the socket base is usually touched at the same time, the risk of an electrical accident is particularly high. This is where the invention provides a remedy.
Es ist deshalb Aufgabe der Erfindung, bei den im Stand der Technik bekannten elektrischen Schutzkontaktsteckdosen mit schraubenlosen Leiteranschlußklemmen einen optimalen Berührungsschutz auch dann zu gewährleisten, wenn die Stromleiter-Montage/Demontage nicht im potentialfreien Zustand und von Hand durchgeführt wird.It is therefore the object of the invention to ensure optimum contact protection in the electrical protective contact sockets known in the prior art with screwless conductor connection terminals even if the current conductor assembly/disassembly is not carried out in a potential-free state and by hand.
Diese Aufgabe wird durch die im einzigen Schutzanspruch gekennzeichneten Merkmale gelöst.This problem is solved by the features characterized in the sole claim.
Erfindungggemäß ist zwischen den schraubenlosen Leiteranschlußklemmen und den Klemmfederlösetasten des Klemmfederlöseorgans eine die Leiteransrhlußkleinmen weitflächig überlappende Abdeckfolie aus elektrisch isolieren-According to the invention, between the screwless conductor connection terminals and the clamping spring release buttons of the clamping spring release device there is a covering film made of electrically insulating material that overlaps the conductor connection terminals over a large area.

dem Material angeordnet. Im Bereich der Drucknocken der Klenunfederlösetasten ist die erfindungsgemäße AbdecRfo lie mit Aussparungen versehen, welche sowohl dem Durchgriff der Drucknocken auf die Klemmfeder der Leiteranschlußklemmen als auch der Fixierung der Abdeckfolie dienen. Durch die erfindungsgemäß angeordnete Abdeckfolie, die alle spannungsführenden Teile weitflächig überlappt, ist selbst bei unvorschriftsmäßiger Montage/Demontage oder vorsätzlichem Berühren des Steckdosensockels ein vollständiger Berührungsschutz gegeben.the material. In the area of the pressure cams of the clamping spring release buttons, the cover film according to the invention is provided with recesses which serve both to allow the pressure cams to reach through to the clamping spring of the conductor connection terminals and to fix the cover film in place. The cover film arranged according to the invention, which overlaps all live parts over a large area, provides complete protection against contact even in the event of improper assembly/disassembly or deliberate touching of the socket base.
