Description

Electrical device with a capacitor large

capacity

The present invention relates to an electrical device having a large capacitance capacitor, in particular an electronic flashlight device.

In electrical devices with capacitors of large capacities, these capacitors require a relatively large volume _s, so that the dimensions of such electrical devices are relatively large and are essentially determined by the size of the capacitors. This is the case, for example, with electronic flash units, which require capacitors with a large capacity to store the necessary amount of charge. Such electrical devices, such as, for example, an electronic flashlight device, should now have small dimensions with the largest possible capacitance of the capacitors. It is therefore the object of the invention; To create an electrical device in which the capacitors, which help determine the volume of the devices, take up as little space as possible while maintaining their capacitance,

This is achieved according to the invention in that the capacitor consists of a flexible tape, which is at least partially encloses the components of the device. This has the advantage that there are no more capacitors with one large and fixed volumes must be used. In any way, the flexible capacitor tape in the electrical device are arranged, with the available spaces in an advantageous manner can be used between the individual components and / or between the modules and the housing.

For example, according to a further development of the invention Device of the capacitor have the shape of a hollow cylinder, in the interior of which at least some of the components the electrical device are housed.

In the case of a housing enclosing the electrical device, the shape of the hollow cylindrical capacitor is according to further Training adapted to the shape of the housing.

The capacitor is expediently around a voltage source, like ZoB. an accumulator and / or at least one elec-

trisch ^ n block wound, with the winding capacitor with the voltage source and / or the module form a fixed unit forms ο This gives the gate part that the capacitor can be installed with the accumulator or an electrical module as a fixed unit in the electrical device. The module or the accumulator serves as a carrier for the capacitor «

The capacitor can of course also be wound on a hollow cylindrical carrier into which the electrical Components can be inserted like drawers ο

In the following, the invention will be described using several embodiments shown in FIGS. 1 to 5. It show ι

The hollow cylindrical capacitor 4 encloses a battery cells 7, 8, 9 and 10 receiving part 11 “With 12 is a holder for denotes the individual battery cells. Furthermore, the hollow cylindrical capacitor 4 encloses an electrical component 13 · Mit 14 denotes a further electrical component which is arranged outside the capacitor 4. At 15 there is a discharge tube designated

In a manner not shown, the condenser 4, wound in the form of a hollow cylinder, is fixed to the inner wall of the housing 1. When the foot part 2 is released from the housing part 1, the battery cells 7 to 10 and optionally also the component 13 can be easily removed from the interior of the hollow cylinder.

According to FIG. 3, 15 denotes an accumulator, the connections of which are denoted by 16 and 17. The accumulator 15 serves as the winding core for the flexible capacitor strip 18. One connection of the capacitor is designated with 19 and the other connection with 20

a similar structural unit, the capacitor 18 is surrounded by an exact 33 ~

The embodiment according to FIG. 4 is 21 with a hollow cylindrical Designated carrier, which serves as a winding core for a flexible capacitor strip 22. The carrier 21 forms a fixed unit with the capacitor band 22. Inside the carrier 21 of the capacitor 22 is like a drawer an accumulator and a further electrical component 24 can be inserted. The connections of the accumulator are marked with 25 and designated,

In the exemplary embodiment according to FIG. 5, 27 denotes a housing in which electrical components 28, 29 and 30 are arranged. A flexible capacitor strip, the beginning of which is designated by 31 and the end of which is designated by 32, partially encloses the component 28, the component 29 and the component 30. The capacitor strip is however also led around all electrical components 28, 29 and 30. Thus, not only the space between the components and the housing 27 is used, but also the space between the individual components 28 to 30.
