Description
Die bisher bekannten Stecker, welche unmittelbar an Heiz- oder Kochgeräte angeschlossen werden, weisen den Nachteil auf, daß die in dem Heizapparat entwickelte Wärme sich auf den Stecker übertragt. Die Folge davon ist, daß die Gummidsolation der Leitung im Innern des Steckers durch die Wärme in kurzer Zeit zerstört wird und von ■den Kupferadern abfällt. Die dann nichtThe previously known plugs, which are connected directly to heating or cooking devices have the disadvantage that the heat developed in the heater is transferred to the connector. the The consequence of this is that the rubber insulation of the cable inside the plug is replaced by the Heat is destroyed in a short time and falls off the ■ copper wires. Then not
ίο mehr isolierten Leiter können sich berühren und dadurch Kurzschluß und Störungen herbeiführen. Die Wirkung der Wärme ist so groß, daß diese nicht nur innerhalb des Stekkers zerstörend auf die elektrischen Leitungen wirkt, sondern selbst noch in einem mehr oder weniger großen Abstand vom Einführungsloch des Steckers entfernt. Auch erwärmt sich der Stecker so stark, daß man ihn mit der ungeschützten Hand aus dem Anschlußapparat nicht herausbringen kann, ohne Gefahr zu laufen, sich zu verbrennen. Hieraus ergibt sich, daß der Verbraucher zum Herausziehen des Steckers an der elektrischen Leitung reißt. Die bisherigen Zugentlastungen können aber eine solche Beanspruchung nicht aushalten, zumal da die am Leitungsende angebrachten Zugentlastungsvorrichtungen ebenfalls durch die Wärme zerstört werden oder infolge der zerstörten Gummiisolation der Leitung nicht mehr wirksam sein können. Hierdurch werden Störungen oder Kurzschlüsse beschleunigt.ίο more insulated conductors can touch and thereby cause short circuits and malfunctions. The effect of heat is like this great that this not only destroys the electrical lines within the connector acts, but even at a more or less large distance from the insertion hole removed from the connector. The plug heats up so much that you can remove it with your unprotected hand Cannot bring out terminal equipment without running the risk of getting burned. This means that the consumer has to pull out the plug on the electrical Line tears. However, the previous strain reliefs can cope with such stress not withstand, especially because of the strain relief devices attached to the end of the line can also be destroyed by the heat or no longer due to the damaged rubber insulation of the cable can be effective. This accelerates malfunctions or short circuits.
Bei dem Stecker nach der Erfindung werden die erwähnten Mängel vermieden.In the connector according to the invention, the shortcomings mentioned are avoided.
Nach der Zeichnung besteht der Stecker aus einem Isolierkörper a, in den ein Rohr b eingesetzt ist. Dieses ist schraubenförmig gewickelt, so daß Windungen entstehen, die zwischen sich Luftspalten frei lassen. Wie man .das gestreckte Metallband, welches für die Herstellung des Einführungsrohres verwendet wird, an einem Ende erhitzen kann, ohne daß sich durch den langen Kariechweg das andere Ende erwärmt, so bleibt auch das dem Stecker abgewandte Ende des Einführ.ungsrohres von der Steckerwärme unbeeinflußt. Aus dem Grunde ist an dem kühl bleibenden Ende des Rohres ein Isolierkörper c zur Unterbringung einer an sich bekannten Zugentlastungsvorrichtung h vorgesehen, die, da sie auch kühl bleibt, nicht unwirksam werden kann.According to the drawing, the connector consists of an insulating body a into which a tube b is inserted. This is wound in a helical manner so that turns are created that leave air gaps between them. Just as one end of the stretched metal band, which is used for the production of the insertion tube, can be heated without the other end being heated by the long Kariechweg, the end of the insertion tube facing away from the connector also remains unaffected by the plug heat . For this reason, an insulating body c is provided at the end of the pipe that remains cool to accommodate a strain relief device h known per se, which, since it also remains cool, cannot become ineffective.
