Abstract

PURPOSE:To improve productivity and magnetic characteristics by surrounding a magnetic substance by a cap made of an insulating synthetic resin coated with a conductor, such as gold, silver, copper or the like through electrodeposition or electroless plating and winding the magnetic substance by the conductor. CONSTITUTION:The ring-shaped magnetic substance 6 is wrapped by the caps 1, 2 made of the insulating synthetic resin, on which copper 3 is electrodeposited, and copper 3 is brought to a wound state. The coil is coated with copper through electrodeposition or electroless plating again, and conductor windings are thickened sufficiently. Copper wires 5 are soldered with the terminals 4 of the conductor windings in the caps, and the copper wires are coated with the insulating synthetic resin, thus obtaining the coil. Accordingly, the coil or transformer of closed magnetic cores of various shapes can be manufactured without depending upon windings, and a wiring pattern can be constituted arbitrarily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a coil or transformer.

The conventional method of winding a coil or transformer is as follows.

1. Direct human winding method.

2. A method of winding copper wire, etc. directly onto a magnetic material using a winding machine.

3. A method of winding a wire around a cap made of insulating synthetic resin and attaching it to a pre-cut magnetic material.

4. A method of winding the cap by attaching the cut cap to a magnetic material and rotating the bobbin.

However, method 1 is unsuitable for mass production, method 2 is unsuitable for manufacturing small quantities of a wide variety of products, method 3 has the drawback of deterioration of magnetic properties due to gaps, and method 4 is unsuitable for mass production. There are drawbacks to not being versatile.

An object of the present invention is to provide a novel method for manufacturing a coil or transformer that improves the above-mentioned drawbacks.

That is, the magnetic material is surrounded by a cap of an insulating synthetic resin coated with a conductive material such as gold, silver, or copper by electrodeposition or electroless plating, and the magnetic material is sealed. At this time, the conductive covered portion is in the same state as a winding. Further, a conductor such as gold, silver, or copper is deposited by electrodeposition or electroless plating to increase the amount of conductor deposited on the conductor deposited portion. Then, a copper wire or the like is connected to the terminal provided on the cap by soldering or the like, and then coated with an insulating synthetic resin to obtain a coil or transformer.

The details will be explained below based on the drawings. FIG. 1 is a perspective view of one embodiment of the present invention, and FIG. 2 is a sectional view taken along line A--A in FIG. A ring-shaped magnetic body 6 is wrapped in caps 1 and 2 made of insulating synthetic resin on which copper 3 is electrodeposited. Here, the copper 3 is in a wound state. This coil is again coated with copper by electrodeposition or electroless plating.

This allows the applied conductor winding to be of sufficient thickness. Also, by soldering the steel wire 5 to the terminal 4 of the conductor winding in the cap and coating it with an insulating synthetic resin, a coil can be obtained.

Therefore, according to the method according to the invention, annular, angular tripod,
In addition, closed magnetic core coils or transformers of any shape can be manufactured without winding, and the wiring (turns) can be configured as desired.Furthermore, coating with insulating synthetic resin can also be applied directly to the magnetic material. It can be done more easily than if you do it.

Further, the synthetic resin cap according to the present invention can be made double. Further, by making the cap made of insulating synthetic resin as thin as possible and making it multilayer, a multilayer winding coil or transformer can be manufactured.

As detailed above, the present invention provides a novel manufacturing method for manufacturing coils or transformers that does not require winding and can be coated easily, and can be applied to a wide variety of coils and transformers. O that can be very beneficial
