（産業上の利用分野）
本考案は、各産業分野において広く使用され得
るトロイダル型コイル装置の改良に関するもので
ある。[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a toroidal coil device that can be widely used in various industrial fields.
（従来の技術）
トロイダル型コイル装置の中には、トロイダル
型コイルを縦位置状態にして箱形のベース内に半
没状に格納し、このベースを介して例えば回路基
板に取付ける形式のものが知られている。(Prior Art) Among toroidal coil devices, there is one in which the toroidal coil is placed in a vertical position and stored semi-submerged in a box-shaped base, and is attached to, for example, a circuit board through this base. Are known.

う方法を用いている。 In this type, when storing the toroidal coil in the base, a support surface (hereinafter referred to as a support curved surface) with a curvature that fits the coil circumferential surface is formed in advance at the bottom of the base, and the coil circumferential surface The coil is placed on this curved support surface with an adhesive interposed between them to fix them together, and in order to take out the leads related to this coil, two through holes are drilled in the center of the curved support surface in advance. A method is used in which the lead is taken out of the base through the through hole.

ースとが共に回路基板に強固に固定されてしまう
ことになる。(Problems to be solved by the invention) In the toroidal coil device configured as described above, the lead through holes are formed directly on the supporting curved surface, so the adhesive interposed between the coil and the supporting curved surface is It also flows into the through hole, causing a phenomenon in which the lead is fixed in the through hole. Therefore, when the coil device in such a state is attached to a circuit board and soldered, both the leads and the base are firmly fixed to the circuit board.

現象を惹き起して、電気接続の品質を著しく低下
させる事態を招来することになる。 Therefore, when this circuit board with a coil device is used in equipment that generates heat, for example, electrical equipment for automobiles such as an electric circuit for controlling fuel injection in an engine, the coil will heat up as the temperature inside the car increases. The base made of plastic and synthetic resin expands thermally, and stress is generated due to the difference in thermal expansion between the two, which acts on the coil side as a force that pulls the coil on the base away from the circuit board. However, in some cases, the copper foil may peel off from the circuit board while the leads, circuit board, and soldered part are still integrated, resulting in a situation where the quality of the electrical connection is significantly degraded. I will be inviting you.

In a toroidal coil device in which a coil with toroidal winding is mounted vertically and the leads of the coil are passed through a lead extraction hole formed in the base and taken out below the base, the diameter of the lead extraction hole is It is formed to be larger than the lead diameter of the coil, and can prevent an adhesive for fixing the coil to the coil mounting recess from flowing into a region between the lead extraction hole and the coil mounting recess. The reason is that a structural adhesive inflow prevention part is provided.

A convex portion 7 is formed from the top surface to the bottom surface, and a blocking step portion 7 is formed on the inner surface of these two convex portions 5 and 6, and its position in the height direction is determined to fix the coil 1. The height H (height from the lowest part of the coil mounting recess 4a) is set so that the adhesive applied to the coil mounting recess 4a does not flow into the blocking step 7. Note that the upper space 7a of this blocking step 7
is formed upright upwardly of the box-shaped base 4 as a cylindrical space having a diameter larger than the diameter of a lead extraction hole 8, which will be described later.

される。 Reference numeral 8 denotes lead extraction holes which are respectively drilled from the two blocking step portions 7 toward the lower surface (bottom surface) of the box-shaped base 4, and the diameter thereof is set to be somewhat larger than the diameter of the lead. Reference numeral 9 denotes a plurality of mounting terminals for supporting and fixing the entire coil device (specifically, the base 4) to a member to be mounted, such as a circuit board (not shown). It is formed as a pin that projects downward.
次に、このような箱状のベース構成を持つトロ
イダル型コイル装置の組立て方を説明する。 Next, a method of assembling a toroidal coil device having such a box-shaped base structure will be explained.

貫通して箱状ベース４の下面に取出される。 First, a suitable adhesive is applied to the coil mounting recess 4a of the box-shaped base 4 or a part of the circumferential surface of the coil 1, and the coil 1 is placed vertically and semi-submerged on the coil mounting recess 4a. Attach it in place and fix it by curing the adhesive. At this time, the two leads 2 and 3 are inserted into their respective lead extraction holes 8, pass through the holes 8, and are extracted to the lower surface of the box-shaped base 4.

It is firmly supported and fixed to the circuit board to be mounted using the two mounting terminals 9, and the leads 2 and 3 are inserted into the lead insertion hole 8 formed in advance on the board side.
The ends of the leads 2 and 3 are soldered to the copper foil pattern of the circuit board on the back side or front side of the board.

ハンダ付け部分には及ばなくなる。 In this embodiment, the blocking step 7 serves as an adhesive inflow blocking section, so even if the ambient temperature of the circuit board rises and the coil 1 or the box-shaped base 4 thermally expands, the coil 1 itself will be damaged by the circuit board. Even if the box-shaped base 4 and the lead 2,
3 and 3 only cause free "positional deviation" relative to each other at the lead extraction hole 8, and the stress acting force due to the difference in thermal expansion between the leads 2 and 3 does not reach the soldered portions of the leads 2 and 3.

を充分に吸収することが出来る。 It should be noted that the leads 2 and 3 are in a state where there is a margin in the length direction from the magnetic core hollow part of the coil 1, that is, the coil 1
Since it extends downward from the base with a predetermined gap with respect to the hollow part of the magnetic core and the end face of the coil, the above-mentioned "mutual misalignment" phenomenon with the box-shaped base 4 occurs. Even in such cases, the "misalignment" can be fully absorbed.
