DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an electric component,
In particular, the present invention relates to electrical components such as coils and transformers suitable for automatic mounting on a printed circuit board.

[0002]

2. Description of the Related Art Some electric components are arranged such that end faces of two components are brought into contact when assembled into one component. For example, in a coil transformer, a central projecting piece of a pair of E-shaped cores is inserted into a bobbin on which a winding is formed as a hollow cylindrical part from both sides of the cylinder, and these are arranged to face each other. Core into the bobbin,
Some have a structure in which the front end surface of the core is brought into contact with one end surface of the I-shaped core.

FIG. 8 shows a state in which a main part of a conventional coil transformer using a pair of E-shaped cores is assembled. A terminal mounting portion 12 in which surface mounting terminals 11 for mounting on a printed circuit board (not shown) protrude from both sides forms a part of a bobbin 14 as a hollow cylindrical component on which a winding 13 is provided. The bobbin 14 has a pair of E-shaped ferrite cores 16, 1,
The central projecting pieces 17, 17 of the 6 are inserted from both sides, respectively, and are arranged such that the ends on the inserted sides are brought into contact with each other.

FIG. 9 shows a completed state of assembly of a coil transformer using the components shown in FIG.
From above the bobbin 14, spring pieces 22R, 22L, 22F and 22B bent in four directions of the core pressing leaf spring 21 are attached so as to press the pair of ferrite cores 16 and 16 from all directions. The upper part of the core pressing leaf spring 21 is flat. This is coil transformer 2
This is because when the component 3 is automatically mounted on a printed circuit board (not shown), the upper part of the core pressing leaf spring 21 is vacuum-sucked to move the component. This is because the surface of the winding 13 of the bobbin 14 is not flat, so that it cannot be vacuum-sucked to this portion.

A bobbin 14 accommodating the winding 13 in the main part of the coil transformer 23 as shown in FIG.
There has been proposed a utility model registration No. 25735 in which a hook portion is provided at a pair of flange portions, and a flat plate is placed so as to straddle the upper portions of these flange portions, and both side portions are hooked by the hook portions.
No. 44.

[0006]

However, in this proposal, since the flat plate is hung by the flange of the bobbin 14, another fixing means is provided for the pair of ferrite cores 16, 16 so that they do not separate. There is a need. In this regard, the coil transformer shown in FIG.
1 is excellent in that the pair of ferrite cores 16 and 16 are simultaneously fixed. However, the proposed coil transformer shown in FIG. 9 has a problem that if the mounting positions of the spring pieces 22R and 22L of the core pressing leaf spring 21 are displaced in the vertical direction, the contact of the opposing surfaces of the core becomes incomplete.

FIGS. 10 to 13 illustrate this problem. FIG. 10 shows the spring pieces 22R and 22L.
Pushes the ferrite cores 16 and 16 at the approximate center in the height direction as indicated by arrows 31 and 32. FIG. 11 omits the illustration of the core pressing leaf spring 21,
Since the ferrite cores 16 and 16 are pressed at the locations indicated by 1 and 32, these end faces 16E ₁ and 16E ₂ are completely adhered.

On the other hand, as shown in FIG.
Pressing of the spring pieces 22R, 22L as indicated by 3, 34
When the position shifts in the height direction, the ferrite cores 16, 16
The force applied to the end face becomes uneven. Therefore, the core pressing
As shown in FIG. 13 in which the illustration of the leaf spring 21 is omitted,
Ferrite cores 16, 16 end faces 16E₁, 16E_TwoEach other
Do not adhere to each other, and a gap 35 is formed.
In this example, the upper part of the ferrite cores 16 is indicated by an arrow 3
3 and 34, the end face 16E ₁, 1
6E_TwoGap occurs at the bottom of the
When the lower portions of the light cores 16 and 16 are pressed,
E₁, 16E_TwoA gap will be generated in the upper part of the.

If the pressing force applied to the ferrite cores 16 and 16 becomes non-uniform or the pressing position is deviated, the end faces 16E ₁ and 16E ₂ do not completely adhere to each other and a gap is generated. A problem such as a reduction in inductance has occurred.

[0025]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments.

FIG. 1 shows the appearance of a coil transformer as an electric component according to an embodiment of the present invention. In the coil transformer 41 of the present embodiment, a terminal mounting portion 43 having surface mounting terminals 42 (not shown on the back side of the drawing) for mounting on a printed circuit board (not shown) projecting from both sides is a hollow cylinder. It forms a part of a bobbin 44 as a part. The bobbin 44 has an E
Projecting pieces 48, 48 at the center of a pair of U-shaped ferrite cores 47, 47 (only one of which is arranged in the front is shown in the figure).
(In the figure, only the protruding piece 48 of one ferrite core 47 is shown.) Is inserted from both sides, and the end faces of the inserted sides are brought into surface contact. On the side and upper portions of the pair of ferrite cores 47, a metal fitting 51 formed by cutting and bending an elastic metal plate into a predetermined shape is attached.

The fixing bracket 51 has a planar upper surface portion 52 disposed so as to cover the bobbin 44.
One side (right side in the figure) of the upper surface portion 52 horizontally arranged in the figure
Are bent downward by 90 degrees to form a vertical convex-shaped core pressing leaf spring base 53. One side portion (the side portion on the near side in the figure) protruding to the side of the core pressing leaf spring base portion 53 extends along the outer shape of the ferrite core 47 by 9 mm.
The first core pressing claw 54 is bent inward by 0 degrees and has a relatively short length. Core pressing leaf spring base 5
The other side protruding to the side of No. 3 (the back side in the figure)
Are bent twice inward by 90 degrees along the outer shape of the other ferrite core 47 (not shown), and
And second core pressing leaf spring side portions 55 and 56 are formed. The end of the second core pressing plate spring side portion 56 opposite to the first core pressing plate spring side portion 55 is further bent inward by 90 degrees along the outer shape of the ferrite core 47, and is relatively short. A second core pressing claw 57 having a length is formed.

FIG. 2 is a view of the coil transformer viewed from above, and FIG. 3 is a view of the coil transformer viewed from the direction of arrow 61 in FIG. FIG. 4 shows this coil transformer in a clockwise direction with reference to arrow 61 in FIG.
This is viewed from a position rotated by 0 degrees. As shown in FIG. 2, the core pressing leaf spring base 53, the first and second core pressing leaf spring side portions 55 and 56, and the first and second core pressing claws 54 and 57 of the fixing bracket 51 are formed as a pair. The ferrite cores 47 surround the side surfaces. The first core pressing plate spring side portion 55 is bent in an arcuate shape inward, and presses the opposing surfaces of the pair of ferrite cores 47, 47 together with the first and second core pressing claws 54, 57. Has become.

FIG. 5 shows a state before the coil transformer is assembled. In the hollow portion 46 of the bobbin 44 on which the winding body 71 is disposed, the central protruding pieces 48, 48 of a pair of E-shaped ferrite cores 47, 47 are inserted from both sides as shown by arrows 72, 73. The end faces of the inserted sides are brought into contact with each other.
The winding body 71 is formed by soldering the end of the winding to the surface mounting terminal 42. When the fixing metal 51 is attached so as to fix the pair of ferrite cores 47, 47 as shown by an arrow 74, the assembly of the coil transformer 41 is completed.

FIG. 6 shows the force applied to a pair of ferrite cores in the coil / transformer of the present embodiment, and FIG. 7 shows the case of the conventional coil / transformer shown in FIG. is there. In the case of the coil transformer 41 of this embodiment shown in FIG.
As shown by arrows 81 to 83, forces are applied to the ends 7 and 47 from three directions to bring these end faces into close contact with each other.
Therefore, these ferrite cores 47 can be stably held. Moreover, as shown in FIGS. 1 to 5, the fixing bracket 51 has a band-like width and surrounds the side surfaces of the pair of ferrite cores 47. Accordingly, the core holding plate spring base 53, the first and second core pressing plate spring side portions 55 and 56, and the first and second core pressing claws 54 and 57 of the fixing bracket 51 are slightly vertically moved. The ferrite cores 47, 47
Can be surely fixed.

On the other hand, in the conventional coil transformer 23 shown in FIG. 7, the ferrite cores 16, 16 are linearly pressed by the spring pieces 22R, 22L, respectively. Therefore, when a force is applied in a state where the spring pieces 22R and 22L are not parallel to each other, a force is applied to two points, and the holding of the ferrite cores 16 and 16 becomes insufficient. In addition, as described above, if the mounting positions of the spring pieces 22R and 22L are shifted in the vertical direction, there is a problem that the contact of the opposing surfaces of the core is incomplete.

Therefore, the coil transformer 4 of the embodiment is
According to 1, since the pair of ferrite cores 47 reliably keep their end faces in contact with each other, it is possible to ensure stable quality. Moreover, the upper surface 5 of the fixing bracket 51
Since 2 is a flat surface, the coil transformer 41 can be moved to a desired place by vacuum-sucking this portion, and the productivity of an apparatus using the coil transformer 41 can be improved.

In the embodiment described above, the coil transformer 4 using a pair of E-shaped ferrite cores 47, 47 is used.
As described above, the present invention can be similarly applied to a coil / transformer in which an E-shaped ferrite core and an I-shaped ferrite core are combined. Further, the present invention can be applied to other electric parts in which two parts are arranged to face each other. Further, the present invention can be similarly applied to a case where a lamination core is used.

Therefore, a supplementary explanation on the case of using the lamination core will be added. Lamination core or lamination type core
In e), a silicon steel strip or an iron-nickel alloy (commonly called permalloy) rolled into a thin plate is punched out by a press die, and these are stacked and used as a magnetic core. Of these, silicon steel strip is mainly used for transformers, generators,
Used for high-power devices such as electric motors. As a coil / transformer in the electric component of the present invention, permalloy, which is an iron-nickel alloy, is easily applied because of the characteristics of the magnetic material.

When a lamination core is used,
It is possible to use the E-type or I-type laminated magnetic core described in this embodiment and the like.

[0036]

As described above, claims 1 to 6 are described.
According to the described invention, when the opposing end surfaces of the two components are brought into surface contact with each other, the side surface of the combined component formed thereby has a length of one side of the opposing surfaces like the four side surfaces of the rectangular parallelepiped. Equally adjacent surfaces are electrical components having two components that are at right angles to each other, and the bow-shaped holding part and the first and second holding claws apply force to the side surfaces of these two parts at three places. In addition, since the pressing portions and the claws are formed in a belt shape, the fixing of these two components can be stabilized with a simple structure, and the quality can be maintained and the efficiency of assembly can be improved. Further, since the flat plate portion is integrally provided, the mounting on the substrate is simplified.

When the ferrite core is used in the invention according to claim 6, (1) the inherent resistivity is relatively large and the eddy current loss is small. As a result, there is a characteristic that the frequency characteristics are good and that high frequencies can be used. Also, (2) processing is easy, and there is no deterioration in magnetic characteristics due to processing. (3) Because of the powder molding, there is also a feature that the shape can be freely designed and the size can be easily reduced. On the other hand, when a lamination core is used, since the magnetic permeability is high, a transformer for transmitting an audio frequency from 300 Hz to 3.4 kHz, for example, requires a large inductance. There is an advantage that the size can be reduced and the size can be reduced. Another characteristic is that the saturation magnetic flux density is large.
