In FIGS. 1 and 2, reference numeral 1 denotes a substrate made of an insulating material, such as paper phenol, epoxy resin, PS, PP.
And the like, which constitutes a so-called printed wiring board.
2A and 2B are planar coils made of a conductor such as a copper member. Reference numeral 3 denotes a lid, which is attached as if the magnet 4 is housed in the base 1. The lid 3 is made of a resin molded member, a pressed metal member, or a ceramic molded product. 4 is a spherical magnet (magnet). Reference numerals 5 denote electrodes, which are disposed at both ends of the base 1, and enable surface mounting on a printed wiring board.

The power generation device 100 in the first embodiment is
A surface-mounted power generator is characterized in that a magnet is mounted on a planar coil of a base so as to roll or slide.

In the embodiment shown in FIG. 1, the spherical magnet 4 is located near the planar coils 2A and 2B. That is, the flat coil 2B rolls in an arbitrary direction on the flat coil 2B.
A current is generated in A and 2B to generate power.

The acting force to roll the spherical magnet 4 is
Alternatively, it is performed by vibrating (swinging), tilting, or carrying around a printed wiring board or the like on which the substrate 1 is surface-mounted in any direction of up, down, left, and right. Of course, even when the base 1 is mounted on a vehicle such as a four-wheeled vehicle, the vehicle starts, stops,
The spherical magnet rolls and generates electricity as the road travels on uneven roads.

Further, when it is attached to a tree or the like, power is generated in response to the swing of the tree due to wind power. Furthermore, when floating on the sea, it generates power by the waves.

Next, an embodiment of the planar coils 2A and 2B constituting the power generator 100 of the present invention will be described with reference to FIG.

The planar coils 2A and 2B shown in FIG. 2 are formed in a coil shape from a metal plate having a thickness of about 0.1 mm to 0.5 mm, such as a copper plate, by means of etching, laser processing, or pressing. It becomes.

The coil is attached and laminated on both sides of the thermoplastic resin sheet or the prepreg resin sheet,
Furthermore, by performing concave pressure processing with a flat plate while heating,
The coil is buried and integrated so that the surface of the coil and the surface of the resin sheet are substantially flush with each other. The planar coil may be a print coil, a print coil, a fusion coil, or the like in addition to the above.

The printed coil is formed, for example, by photoetching a double-sided or single-sided copper-clad flexible wiring board to form a spiral planar coil, and laminating one or more layers via an insulating layer.

The spiral planar coils are electrically connected in series by means of copper plating or the like via through holes so that current flows in the spiral planar coils in the same direction. Naturally, both surfaces of the planar coil are covered with an insulating layer, for example, an epoxy resin, a fluorine resin or the like. The coating promotes the rolling or sliding of the magnet and prevents wear of the coil.

The printed coil is formed, for example, by screen-printing a conductive paste on both sides of a ceramic substrate and baking to form a spiral planar coil. The spiral coil is electrically connected in series with each spiral via a through hole provided in advance. The coil is connected to the planar coil so that current flows in the same direction, and is covered with an insulating layer.

The fusion coil winds a fusible insulated conductor,
It is stuck. The fusible insulated wire is a double-structured covered wire in which a fusible film such as a thermoplastic resin or a thermosetting resin is baked on a covered wire such as polyurethane or polyester.

That is, by reducing the size of the plate-like ferromagnetic material or the interval between them, the coil (inductor) can be reduced in size and thickness. The fusion coil is mounted on a rectangular chip-type printed wiring board or the like.

FIG. 3 shows a planar fusion coil unit.
The cross section is 0.06 x 0.65 mm as a fusible insulated conductor.
Winding was performed using the # 2 ribbon conductor, and the conductors were bonded and formed by heating with hot air. External dimensions are about 25m in diameter

Further, the planar fusion coil does not necessarily have to be a single coil body.

The plate-like plates 8 arranged on both sides of the fusion coil are made of an oxide soft magnetic material (ferrite) such as Mn-Zn or Ni-Zn, an amorphous alloy such as Co or Fe, or an amorphous alloy.

Then, the magnetic layers on which the conductive layers are printed are overlapped and pressed, and the upper and lower conductive layers are connected through the through holes 12 to form a coil in the magnetic laminate. Since the green sheets can be laminated together, the number of manufacturing steps is reduced.
