Description
Elektrische installatie-schakelaar met sluitcilinder en veiligheidsinrichtingElectrical installation switch with locking cylinder and safety device
De vernieuwing heeft betrekking op een elektrische installatie-schakelaar volgens de aanhef van conclusie 1.The innovation relates to an electrical installation switch according to the preamble of claim 1.
5 De tot dusver gebruikte metalen installatieschakelaar- behuizingen hebben op grond van hun eigenschappen de sluitcilinder opgenomen in de betreffende maatregel van bescherming tegen spanningsvoerende onderdelen. Aangezien voor schakelaars van elektrische installaties in toenemende mate 10 kunststof behuizingen worden gebruikt, is de bovengenoemde maatregel niet effectief, dat wil zeggen, het is nodig om een elektrische verbinding tussen sluitcilinder en veilig-heidsaardedraad tot stand te brengen.5 The metal installation switch housings used hitherto, by virtue of their properties, have included the locking cylinder in the appropriate measure of protection against live parts. Since plastic housings are increasingly used for switches of electrical installations, the above measure is not effective, i.e. it is necessary to establish an electrical connection between locking cylinder and protective earth wire.
Het is daarom het doel van de vernieuwing, een inrich-15 ting voor elektrische installatie-schakelaars met sluit-cilinders te ontwikkelen, die de beveiliging tegen het aanraken van metalen spanningsvoerende onderdelen ook in geval van storing garandeert.The aim of the innovation is therefore to develop a device for electrical installation switches with locking cylinders, which guarantees protection against contact with metal live parts even in case of failure.
Volgens de vernieuwing wordt dit doel door de in het 20 kenmerk van conclusie 1 aangegeven maatregelen bereikt. Gunstige verdere uitwerkingen zijn onderwerp van de volgcon-clusies.According to the innovation, this object is achieved by the measures indicated in the characteristic of claim 1. Advantageous further elaborations are the subject of the subclaims.
Aan de hand van een tekeningfiguur wordt in het onderstaande een uitvoeringsvoorbeeld overeenkomstig de vernieu-25 wing nader toegelicht.An exemplary embodiment according to the innovation will be explained in more detail below with reference to a drawing figure.
De tekening toont in een aanzicht met uiteengenomen opbouw de afbeelding van een elektrische installatie-schakelaar in de vorm van een tegen water beschermd opbouwtoestel.The drawing shows, in exploded view, the image of an electrical installation switch in the form of a water-protected surface-mounted device.
De installatieschakelaar volgens de vernieuwing is 30 samengesteld uit een huisonderdeel 1, een schakelaar-inzet-stuk 2 en een huisbovendeel 3, waarbij in het huisbovendeel 3 een sluitcilinder 4 is ondergebracht.The installation switch according to the innovation is composed of a housing part 1, a switch insert 2 and a housing upper part 3, a locking cylinder 4 being housed in the housing upper part 3.
Het afbeelden van voor de vernieuwing niet relevante maatregelen werd nadrukkelijk achterwege gelaten.The representation of measures not relevant for the renewal was expressly omitted.
35 Zoals uit de tekeningfiguur blijkt, wordt het schake- laar-inzetstuk 2 met zijn aardecontact 6 in het huisonderdeel 1 geplaatst, waarbij de veiligheidsaardedraad 7 reeds elektrisch verbonden is met het aardecontact 6, daarna wordt 1004255 2 het huisbovendeel 3 met de ingebouwde sluitcilinder 4 via de aardingssteker 5 en het aardecontact 6 verbonden met de sluitcilinder 7. Door deze opbouw is de beveiliging tegen het aanraken van spanningsvoerende onderdelen ook in geval 5 van storing gewaarborgd. Overeenkomstig kan deze beveili-gingsinrichting ook voor inbouwtoestellen worden gebruikt.As shown in the drawing figure, the switch insert 2 with its earth contact 6 is placed in the housing part 1, the protective earth wire 7 is already electrically connected to the earth contact 6, after that 1004255 2 becomes the housing upper part 3 with the built-in locking cylinder 4 connected via the earthing plug 5 and the earthing contact 6 to the locking cylinder 7. This construction ensures protection against contact with live parts even in the event of a fault. Accordingly, this protection device can also be used for built-in appliances.
