Abstract

PURPOSE:To eliminate electrical contact part, prevent an accident by electric shock and realize reduction in size by providing a high frequency power supply which converts a commercial power source into a high frequency, a core A winding the primary coil connected to the high frequency power supply and a core B winding the secondary coil which is magnetically and mechanically coupled to the core A 6 and supplies a power to a load Z connected. CONSTITUTION:After full wave rectification by a diode bridge 2, a high frequency signal of, for example, 10kHz and 20kHz, etc. is obtained from a commercial power source frequency by a multivibrator 8 and this high frequency signal is applied to the base of transistor 4. Thereby, the commercial power source is converted to a high frequency signal. The core A 6 is capable of reducing a loss for use in a high frequency by using a material having a high residual magnetic flux density, for example, ferrite or permalloy and is formed like a letter E. The primary core B 12 is also capable of reducing a loss by using a material having a high residual magnetic flux density and is formed like a letter E. When the core 12 is abutted with the core A 6, the core B 12 is magnetically and mechanically coupled with the core A 6, owing to the magnetic field induced on the primary coil 7 and then supplies a power to the load Z.

It takes a form. The branch is made of core B, which reduces loss by using a material with high residual magnetic flux density like the core A6, and is formed into the same E shape as the core A6, and the secondary side is connected to the load 2.

The core B12 is magnetically and mechanically coupled to the core 86 by the electromagnetic field induced in the next coil 7, and supplies power to the load Z. Incidentally, the secondary coil 7 and the secondary coil field may be wound directly around the core A6 and the core B12 without using the coil bobbins 8 and 14. In this embodiment, the core B]2 is attached to the container L5 and used in the same manner as a conventional plug. However, when the core B12 is brought into contact with the core A, the contact position is shifted due to the weight of the core BL2, and the core B12 is moved from the core A6 to the core B12.
In order to prevent the magnetic permeability from decreasing, a recess (not shown) for supporting the container 15 may be formed in the lid 10.

A power supply characterized by comprising a core B12 wound with a secondary coil field that is magnetically and mechanically coupled to the core A6 by an induced electromagnetic field and supplies power to the connected load 2. Since the device is made into a device, there is no need for electrical contact parts and electric shock accidents can be prevented, and since it uses electromagnetic induction, it can be used in places where there is water, such as a bathroom or kitchen, or even underwater. In addition, by converting the commercial power source 5 to a high frequency, the dimensions of the core A6 and core B12 are smaller, and the number of turns of the primary coil 7 and secondary coil L'13 can be reduced, resulting in a smaller device. Since there is no need to provide a plug blade insertion opening or a plug blade as in conventional outlets and plugs, a power supply device with improved aesthetic appearance can be obtained.
