German Gasglühlicht-Äuer-Gesellschaft m. B. H. in Berlin. Device socket, in particular for heating and cooking devices.

Patented in the German Empire on January 21, 1926.

Experience has shown that the lead in movable electrical equipment such. B. in heating and cooking equipment, represents the most sensitive part, and that the failure of such devices is largely due to faults in the supply line. According to the regulations of the VDE, the supply cord should be relieved of tension at the device socket as well as at the wall socket and protected against twisting the risk of body injury is prevented during normal use. However, the term "normal use" can be ¹ S difficult to define, and it is therefore to further increase the safety of the general

Exit of the supply line from the tea pot still especially protected by the fact that a metal hose or a metal spiral is used when the cord emerges from the device socket. Especially bed iron, who are exposed to constant movement back and forth becomes the exit point - the cord from the appliance socket mostly has a more or less strong bend

ίο or kinking exposed. And around this bend as small and harmless as possible a metal spiral hose is provided. Despite all these protective measures but there is still the possibility that with frequent and careless In the course of time, the supply line becomes brittle at this point, especially since it is used Place close to the heating zone and thus) ,, especially if it has been flattened for hours, it is heated. If the insulation of the Stranded wire then there is the possibility that the bare stranded wire is in contact with the metal hose and thus also with the protective metal jacket that is often present on the device socket comes and causes a body closure.

The invention has the purpose of remedying this deficiency by creating a trumpet-shaped Protective insulation on the endangered

3Q position is provided. The invention is illustrated in the .Zeichnung is α, a metallic spiral tube, b its lower extension, which c in the correspondingly shaped protective metal shell of the connector socket EDN ■ accesses. "D represents a Isoliierteil, which at the lower end corresponding to the extension of the protective metal spiral trumpet-like expands, and thus -protects the. Leitungssehnur e at embrittlement prior to contact with the metal parts of Sehutzschlau'ches and the protective jacket. the insulating member d must be made of heat-resistant ,, flexible material, o such. B. particularly a prepared asbestos fabric. etc. The length of the part depends on the dimensions of the device socket and the metallic spiral hose.

Claims (1)

Claim: Device socket, in particular for heating 50, and cooking devices, characterized in that an insulating piece (d), widened like a trumpet at its lower end, made of heat-resistant, flexible material, prevents the line from touching the metallic when the line cord (e) becomes brittle Spiral hose (a) and the metallic casing (c) of the device socket.
