Definitions

  • the invention relates to an electrical connection device with current leads and contact arrangements.
  • the lampholders have two contacts, which are designed as side contacts and resilient center contacts for sockets for light bulbs with Edison thread, and as resilient contacts next to one another for sockets for lamps with bayonet bases.
  • the sockets have two sockets into which the plug pins of a plug can be inserted through holes in a cover.
  • connection devices have the disadvantage that the contacts or sockets are connected directly to the connection elements for the power supply lines, so that the contacts are freely accessible when the lamp or the plug is removed.
  • Sockets are based essentially on the same principle, in which a cover is provided above the plug-in sections, which is displaced when the plug is inserted and releases the sockets.
  • the sockets have the disadvantage that they are very susceptible to faults due to the mechanical structure of the cover, i.e. the cover is no longer moved, so that the sockets are no longer released or are no longer covered.
  • the purpose of the invention is to remedy the disadvantages indicated.
  • the object is to create an electrical connection device in which the current flow between the power supply and the contact arrangement is interrupted by at least one isolating section when no electrical consumer is connected to the connection device.

Abstract

Le dispositif presente des bornes d'amenee de courant et un agencement de contact (6, 7) dispose sur un support (5). L'agencement de contact comporte des organes interrupteurs avec deux espaces de coupure. Chaque organe interrupteur est muni d'au moins deux pieces de contact (35, 36, 37; 55, 56, 57) deplacables l'une vers l'autre sous l'effet d'une force exterieure afin de fermer les espaces de coupure. Les organes interrupteurs sont verrouilles mecaniquement et/ou electriquement l'un par rapport a l'aure afin d'empecher la conduction du courant lors d'un attouchement.
