Abstract

PURPOSE:To eliminate the winding process and to greatly reduce a thickness by a construction wherein a zig-zag conductive pattern is separated by cut-outs into plural parts which are arranged on the upper and lower sides alternately with respect to a plane. CONSTITUTION:A zig-zag pattern 27 is formed with a copper foil 26 on a flexible board 25. Terminals 28, 29 are led out from both ends of the pattern 27. Then, the board 25 is separated by plural cut-outs into upper and lower parts alternately. A flat core 31 formed of ferrite, etc. is inserted to a space defined by those alternate upper and lower parts. Thus, the core 31 assumes such a state that conductive wires are wound around it.

Description

[Detailed Description of the Invention] This invention is an inductance element arranged on a wiring board! This is what we intend to provide.

As an inductance element for conventional circuit wiring.

In general, a bobbin (1) with 7 lunges of 15K, for example, IIJIII, as shown in Fig. 511, is provided with a lead 11 (2).

For example, in the case of a filter configuration consisting of inductance elements (3) and (4) and a capacitor (5) as shown in the equivalent circuit of Diagram 2, it is configured as 5 in FIG.

That is, a capacitor is formed by forming adjustment shafts on both front and back surfaces of the dielectric insulating base II (9). Then, as shown in KIIK on this board (9), conductor wires are wound around the bobbin = illuminance υ and al are pasted,
When the αυ and n terminals of the coil are connected to the capacitor,
8'+ are respectively derived.

Terminals <4) <4><ti) correspond to terminals (6), (7), and (8) of the equivalent circuit in FIG.

When a large number of these 15 LC filters are connected to form, for example, a ladder circuit, the implementation of the Oshiro configuration is as shown in FIG. 4. That is, a plurality of substrates (1:I (
14) (is- are arranged so that they are stacked in parallel as shown in the figure. In this case, the distance between the substrates when they are arranged so that they are stacked is @d
There is a coil on each board Q41 ui a.
9ci! Since Ij, (2m)fJ, and (2) (to) are provided respectively, it is limited and requires a considerable amount of extra space.

Moreover, in practice, a coil constructed by winding lead wire around a pobbin has the disadvantage that it requires a lot of effort.

This project aims to create a new inductance 7*@L that can easily eliminate the drawbacks of the conventional coils that are wound around the wire rod bobbin. .

Below is an example of an inductance element using this method: 1
Let's explain with reference to Figure IIs below.

In the example shown in the figure, a flexible base 41 is used as an inductance element, and the structure is as shown in 5 below. That is, the first f1
Form one zigzag pattern on K11lliv4 on the flexible substrate (c) so that g5wJrc is not removed. And one end of this zigzag pattern (2), 4i! Lead out the 41 machined terminal @@ze. Furthermore, this zigzag-like pattern (Ilo's 4N14fk @ Zheng-bun is not cut, as shown by -), a slight incision is made in this flexible board (2), and the 6th
rIAK As shown, the flexible substrate is divided alternately into upper and lower parts with this number of notches &) as the border. In other words, zigzag-shaped steel foils (c) are placed alternately above and below one surface. Then, a flat core 6υ made of ferrite, for example, is inserted into the space left after being raised and lowered alternately. In this way, a state similar to that in which a conductive wire is wound around the ferrite core Gυ is obtained, and an inductance element can be easily formed. Moreover, in this case, ferrite core c11
Although it has some thickness, it can be used as an inductance element that is extremely flat and thin. Therefore, when making a 5 LC filter as shown in the equivalent circuit of Figure 2, g7
As shown in taK, a single electric board (9
) by applying the above-mentioned inductance element u3 (to) through an insulating material, a very thin layer can be realized.

The above example is a case where the steel foil (C) is arranged in a zigzag pattern on the flexible base *c251.
At 11, a copper foil is applied on the - side as indicated by the diagonal *1, and a cut is made into this steel foil (towards) to make a moxibustion. 4 foils (2) may be zigzag.

Although the inductance element in the above example has a high Q, the comparative inductance value is small. To increase the inductance value, do the following:

In other words, Figure 5119 is an example of this, and the copper foil (2) on the board (to)
), sandwiching the ferrite core 61 inserted into the zigzag conductive pattern, and as shown in the figure, the ferrite cores and (to) are the cores, and 6υ is the empty I! IC! Provided to form @ and 6D. In this case, at the end of the core 6υ in the direction of insertion into the jig-dag conductive pattern,
The core (to) (to) and this core 61 are joined.

Such a sand inch structure not only increases the inductance value, but also causes a problem with the outside on the east side.

Note that the example of 纅sg is a case where ferrite cores (to) are provided on both sides of the core Gυ to form a sandwich structure, but even if the ferrite core v9 is placed only on one side of the core 431, the inductance value will increase. The purpose is i
A: I can express it.

The above example is a case of a flattened zigzag putter with 100 million inductance elements made by 7111 people, but the following 15
By doing so, it is possible to realize an inductance element 4h, which is unlike any other.

In other words! 10 aiI shows one example,
Each zigzag part ψ) of the 5vA flexible board (C) is shown in the figure ψ)t1, so that it is shaped in a straight line, and the shape is alternated with the south corner part of the line through the cut l-. Shape. Then, in the example shown in the figure, the zigzag 411E body parts of the E-shaped core @ which are adjacent to each other through the cut 01Jr are placed above and below each other, and each steel foil part has the E-shaped core ■'? ! Legs of r4 (318A) (38B) (380) K are to be inserted alternately up and down in 4 ways. In this case, the other end of the E-shaped core is connected to the ■-shaped core, as shown in Figure 1mj, to form a Japanese-shaped inductance element.

When inserted into this E-shaped = A-eav zigzag conductive pattern, it becomes 3. In other words, the 3 legs (38 people) (38B) (3
The direction of the magnetic path passing through the steel foil section t is as shown by the solid line in the figure.
8A) (38B) (38C) They are opposite to each other when busy.

Furthermore, the transformer can be easily constructed as follows.

In other words, the 7 lexical number 1 [1
Prepare 12 sheets of 4G (41) and stack them in a stack so that each terminal part of the base 1 [■ axis υ is in a different direction from each other, as shown in Figure 11112. Then, the zigzag conductive pattern parts of both are placed in the same position, and as shown in Figure 12 and Figure 1311, both zigzag conductive patterns are arranged alternately with the notch (b) shown by the broken line as the border. Insert 4 flat ferrite cores (41v1) into these so that they are vertically aligned. In other words, overlap so that the notches (6) of the flexible board WJ@υ of 2019 are at the same position. In this way. Then, in the zigzag pattern part, the steel foil @4
- is overlapping in summer - to form a 5-layer structure, and each of the overlapping pieces is cut into two pieces, and the adjacent pieces are placed one above the other.

In this way, an inductance element made of copper lI- on one 7 lexical board and an inductance element made of copper i on the other 7 lexical board
The L transformer is realized through the transformer.

As mentioned above, this release I! According to j, emergency ec*s+
The inductance element has been realized, and it requires only 4I screws.
The i which is not necessary at all is self-realized, so when it is formed as a Phil-Seven Ladder shadow circuit consisting of the inmetances 1st and 2ndenna as mentioned at the beginning, When arranging VIl as shown in 114-, the distance #Ii between the two substrates becomes very close, and the actual output * can be considerably increased. Things slow down. And uI of -! Since the elements can be arranged in the Q space, it is possible to make the structure into a very small part.

Another advantage of this method is that it does not require a winding machine as much as the conventional method, making manufacturing very easy.

Furthermore, 7 Lexiple! Other steel mst materials can also be used without using I[t'. That is, in that case, the portions that should be above and below the core may be shaped in advance by tearing or pressing 15. Note that, of course, a blank inductance element can also be constructed. That is, instead of the ferrite core, it may be inserted into an inductance element made of a non-conductive material t flexible substrate.
