Description
Steckdosen mit Schutzkontakten, die unter der Bezeichnung Schukodosen bekannt sind, besitzen einen Schutzkragen, in dem seitlich von Federn getragene Schutzkontakte angeordnet sind, die sich in radialer Richtung gegen einen entsprechenden Kontakt des eingesetzten Steckers anlegen.Sockets with protective contacts, which are known as Schuko sockets, have a protective collar in which protective contacts are laterally carried by springs and which are located Apply in the radial direction against a corresponding contact of the plug used.
Beim Überschieben der Dosenkappe über den Dosensockel werden die Blattfedern, an denen die Schutzkontaktfinger befestigt sind, oft über dieWhen the can cap is pushed over the can base, the leaf springs on which the Protective contact fingers are attached, often via the
ίο Elastizitätsgrenze hinaus so nach außen gebogen, daß eine bleibende Formänderung eintritt und die Berührung der Kontaktflächen am Stecker nicht mehr mit Sicherheit erfolgt. Man hat daher schon auf der Außenseite der Blattfedern Verstärkungsfedern angebracht, eine Maßnahme, die jedoch auch nicht in jedem Falle sicher wirkt. Es gibt aber auch Fälle, in. denen die Steckdose sich durch irgendwelche Umstände erwärmt, z. B. wenn die Steckdose in einem Raum angebracht ist, in demίο the elastic limit bent outwards so that that a permanent change in shape occurs and the contact with the contact surfaces on the plug does not more certainly done. There are therefore reinforcement springs on the outside of the leaf springs appropriate, a measure which, however, does not work safely in every case. But there is also cases in which the socket heats up due to some circumstances, e.g. B. if the Socket is installed in a room in which
ao eine übernormale Temperatur vorhanden ist. Durch die Wärme werden die Blattfedern, an denen die Schutzkontaktfinger befestigt sind, mit erwärmt, und erlahmen infolgedessen in ihrem Kontaktdruck·. ao the temperature is above normal. The leaf springs on which the Protective contact fingers are attached, with heated, and consequently weaken in their contact pressure ·.
Durch die Erfindung soll dieser Nachteil beseitigt werden. Erfindungsgemäß werden die Blattfedern,, an denen sich die Schutzkontaktfinger befinden, bei ansteigender Temperatur auf ihrer Außenseite, durch Verstärkungsfedern aus Bimetall in ihrem Kontaktdruck unterstützt.This disadvantage is to be eliminated by the invention. According to the invention, the leaf springs, on which the protective contact fingers are located, when the temperature rises on their outside, by means of reinforcement springs made of bimetal supported in their contact pressure.
Bei einem bevorzugten A.usführungsbeispiel bestehen die die Kontaktringer tragenden Blattfedern selbst aus Bimetall, dessen Anteil mit größerer Längendehnung außen liegt.In a preferred embodiment, there are leaf springs carrying the contact rings even made of bimetal, the proportion of which is on the outside with greater elongation.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsschnitt dargestellt. In the drawing, an embodiment of the subject invention is shown in longitudinal section.
Auf dem Kontaktträgersockel 1 ist die Blattfeder 2, welche an ihren Enden die Kontaktfinger 3 trägt,, befestigt. Die Befestigung der Blattfedern 2 kann sowohl, wie dargestellt, auf der Unterseite des Hohlsockels als auch auf seiner Oberseite erfolgen. Die Blattfedern werden durch die außen an sie angelegten Bimetallfedern 4 in ihrem Kontaktdruck unterstützt. Die Bimetallfedern 4 sind zusammen mit den Kontaktfedern 2 durch Metallbüchsen 5 an dem Sockel befestigt, wobei die Metallbüchsen 5 gleichzeitig mit einem Innengewinde zur Aufnahme der Kappenbefestigungsschrauben versehen sind. Bei einer bevorzugten Ausführungsform bilden die Blattfedern 2 mit einem Streifen 4 anderen Metalls größerer Längendehnung einen Bimetallkörper. Bimetallformlinge behalten nach dem Tempern ihre Endform endgültig bei.On the contact carrier base 1 is the leaf spring 2, which has the contact fingers 3 at its ends carries ,, attached. The attachment of the leaf springs 2 can be done both, as shown, on the underside of the hollow base and on its upper side. The leaf springs are in their contact pressure by the bimetallic springs 4 applied to them on the outside supports. The bimetal springs 4 are together with the contact springs 2 by metal sleeves 5 attached to the base, the metal sleeves 5 at the same time with an internal thread are provided to accommodate the cap fastening screws. With a preferred Embodiment form the leaf springs 2 with a strip 4 of other metal of greater elongation a bimetal body. Bimetal moldings finally retain their final shape after tempering at.
