FIG. 1 is a perspective view conceptually showing a mounting state of a non-contact type transformer on an electric wire, and FIG. 2 is a perspective view of the non-contact type transformer of FIG. It is a figure which expands and shows an internal structure. In the figure, (1) is an electric wire coated with vinyl on the core wire (2), (31) to (38) are fibrous, and the lengths of the fibers are arranged orthogonally to the length of the core wire (2). Magnetic core, (4) is a coil made of copper wire coated with enamel and is wound around magnetic cores (31) to (38), and (5) is magnetic core (3
It is a mesh-shaped magnetic body composed of 1) to (38) and a coil (4).

In the non-contact type transformer configured as described above, the core wire (2) has a commercial power frequency of 50 Hz or 60 Hz.
Current flows in the core wire (2) at a certain time in the direction of arrow I shown in FIG. At this time, the magnetic flux Φ shown in FIG. 1 is generated along the circumference surrounding the core wire (2) as the central axis, and its direction is that the direction of the current is the right-hand screw traveling direction and the right-hand screw is tightened. It becomes the direction of rotation. This magnetic flux Φ enters the mesh-shaped magnetic body (5) and enters the magnetic core (3
Enter 1) to (38). Then, the magnetic flux Φ passing through the magnetic cores (31) to (38) simultaneously changes because the direction of the current I flowing through the core wire (2) changes according to the commercial power supply frequency.

An electromagnetic induction action is generated by the change of the magnetic flux Φ, and electric power is induced in the coil (4) wound around the magnetic cores (31) to (38).

As a result, it is possible to obtain a non-contact type transformer capable of supplying electric power to electronic equipment at all locations along the appropriate electric wire (1) through which an alternating current flows. This eliminates the problem that the movement of the electronic device is restricted and the operability of the electronic device is impaired by providing the power feeding cable between the electronic device and the outlet plug. Also, the operator of the electronic device may accidentally hook the power supply cable to interrupt the power supply, disconnect the power supply cable, etc., and if the power of multiple electronic devices is required, the number of outlets may be insufficient. Problems such as are solved.

The number of magnetic cores (31) to (38) is increased to
