1. Description of the invention:

<L Electrical device, such as a battery-operated lamp, with electrical I
Contact connection to the holder using permanent magnets.

1.1. Purpose of the invention

The component uses permanent magnets to enable electrical connection of devices to a wall bracket and at the same time serves as a fastening for the devices.

1.2. Status of technology

To attach rechargeable electronic devices (e.g. battery lamps with 12 V charging voltage) to wall brackets, permanent magnets are used, which are firmly connected to the device.

i.>, Criticism of the state of the art

These devices must be connected to the power supply using a plug for charging. In addition, these power connections always pose a risk as soon as the jack plug is pulled out of the device without interrupting the connection to the power supply.

1.4. Solution

The invention is based on the task of simultaneously, so to speak, automatically, connecting the devices to the power grid or interrupting the power supply to the contact connection of the holder by means of magnets. This is made possible by a reed contact which is built into the housing exactly under the ceramic plate of the holder. By putting on the magnets of the device to be connected, the power supply to the contact connection of the holder is now disconnected, by the movement of the magnets towards the

<t Magnet the power supply is interrupted again.

':.- 1.5· Advantages

Connecting the devices using a jack plug is no longer necessary, as a built-in reed contact supplies power through the magnetic field of the fastening magnets.

^r If the device is removed from the holder _O , the power supply is automatically interrupted by the removal of the magnet with the help of the reed contact. A danger such as that posed by connected but not inserted jack plugs is completely excluded. ■ )

1.6. Description of the invention

An embodiment is explained using figures 1 to 3.

Figure 1 and 2 a rechargeable hand lamp Figure 3 a wall bracket for electrical connection and

for attaching the hand lamp

In Figure 1, 1 indicates the "plus" contact connection to the lamp.

In Figure 2, 1 denotes two permanent magnets, and 2 denotes a metal plate positioned vertically between the two magnets.

In Figure 3, 1 is the plastic housing of the holder, 2 is the "plus" power supply, 3 is the "minus" power supply, 4 is a reed contact installed exactly under the hole in the metal plate, 5 is a metal plate, 6 is a "plus" contact connection and 7 is a relay. If the lamp is now placed on the holder, the reed contact (Figure 3, item 4), which is located exactly under the ^first hole in the metal plate, is ^closed due to the action of the magnets, whereby the battery is charged via the "plus" ^contacts (Figure 1, item 1 and "minus", pink. 6), especially via the "inverter" contacts. on ',akte (r'ir<ur Z, .ns. ,.' am ';, i'üs , p) der JtrornKrei r; --;rsc:ilo8f;en if;·..

The result of my research is that there has been a utility model for fastening electrical devices for some time, but a utility model which automatically ensures a secure electrical connection to the power source when a device is fastened is still pending.
