Definitions

  • the invention relates to an electrical device with a housing for accommodating at least one functional part and at least one rechargeable memory cell that can be connected to the functional part, a memory cell charging circuit and a device plug provided on the electrical device and connected to the memory cell charging circuit, in whose insertion opening at least two plug pins are arranged and a device socket for the transmission of a mains voltage can be positively inserted.
  • Such electrical devices operated by means of rechargeable storage cells such as, for example, razors, toothbrushes, screwdrivers, drills, flashlights, etc. are in practical use in large numbers.
  • these electrical devices are equipped with a connector plug standardized for safety reasons, in the insertion opening of which a standardized device socket of a mains cable for transmitting a mains voltage can also be inserted in a form-fitting manner.
  • the utility of such electrical devices is very high because the storage cells can be repeated and recharged very often. After each charging process, a fully functional electrical device is available, which can then be used without a mains cable connection.
  • the memory cell charging circuit of such electrical devices is provided with further electrical components which, regardless of the state of charge of the memory cells, ensure operation of the electrical device by means of a direct mains voltage supply.
  • Rechargeable memory cells are known to have a limited lifespan. Accordingly, electrical devices equipped with rechargeable storage cells should be designed such that a safe disposal of used storage cells can be carried out.
  • the object of the invention is to design an electrical device of the type specified in such a way that the rechargeable memory cell (s) can be removed from the electrical device in a simple manner without the operator being able to come into contact with the dangerous mains voltage .
  • a component carrying the connector pins and the connector housing surrounding the connector pins of the device connector are mounted such that they can be moved relative to one another to a limited extent, and in that the housing and / or a housing part which can be removed from the housing the plug socket housing or the component carrying the plug pins can be locked or unlocked by means of the limited mobility and by means of interacting locking elements which are provided on a removable housing or housing part and on the plug socket housing or on a component carrying the plug pins.
  • the electrical device can be opened very easily by the operator.
  • the lock existing between the plug socket housing or the components carrying the plug pins and the housing or a housing part that can be removed from the housing can be put into an unlocked state by rotating the plug socket housing or the component carrying the plug pins and thus the housing or the housing part that can be removed from the housing can be removed from the electrical device .
  • the intended memory cell (s) is then freely accessible and can be removed or replaced.
  • a change in position of the connector pins within the connector opening of the connector housing of the device connector results from the proposed change in the spatial assignment of opposite side walls of the insertion opening of a connector socket housing surrounding the connector pins.
  • This change in position of the plug pins allows a positive plug connection of the device plug and the device socket of a mains cable for transmitting a mains voltage only in the case of a housing located in the locked state with the plug socket housing or the component carrying the plug pins or with a housing part which can be removed from it also the initiation of a rotary movement either of the plug socket housing or of the component carrying the plug pins in a device socket of a mains cable located in the device plug. This ensures that the electrical device can only be opened when the device socket is not in the connector housing of the device plug.
