本発明は、コイルとコンデンサを内蔵したフィルタ部品
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter component incorporating a coil and a capacitor.
従米久弦意表】ｌ
一般に、ＡＣノイズフィルタとしては、金属製ケースに
コイルとコンデンサを収容して樹脂で固め、ケースの開
口部に金属製蓋部材を取り付けたものが提供されている
。このものでは、蓋部材に基板に対する取付は片（例え

るため、蓋部材をケースにかなり強固に固定する必要が
ある。In general, AC noise filters are provided in which a coil and a capacitor are housed in a metal case, hardened with resin, and a metal lid member is attached to the opening of the case. In this case, since the lid member is provided with a piece (for example, a hole is formed for passing a screw) for attachment to the substrate, it is necessary to fix the lid member to the case fairly firmly.
従来ではスポット溶接や半田付けが行なわれていたが、
これらの工程は時間を要し、コスト低減の障害となって
いた。Traditionally, spot welding and soldering were used,
These steps take time and have been an obstacle to cost reduction.
そこで、本発明の課題は、蓋部材をそれ程の強度を必要
とすることなく簡単にケースに取り付けることができる
フィルタ部品を提供することにある。Therefore, an object of the present invention is to provide a filter component that allows the lid member to be easily attached to a case without requiring much strength.

定され、特別な取付は工程が不要となる。In order to solve the above-mentioned problems, the filter component according to the present invention first includes a case made of a conductive metal material with a piece for attachment to a substrate. As a result, the lid member is no longer attached to the board as a part, and the fixing strength to the case is no longer a problem. Then, legs were provided protrudingly on the lid member, preferably at the four corners, and these legs were embedded in a resin for fixing the LC element. As a result, the lid member is fixed to the case during the process of attaching the resin surface of the LC element, and no special installation process is required.

The wires are connected including ゜24. The coil 20 and the capacitors 21, 22, 22 are housed in the case 1 and fixed by casting resin 9 into the case 1 to approximately half the depth. Each terminal 23.24 is a resin terminal block 25
By setting the terminal block 2 in the slit 2, that is, the terminal block 2
It is fixed to the case 1 by engaging the groove 26 formed around the slit 5 with the edge of the slit 2 .

is placed over the opening of the case 1 before the casting resin 9 has yet hardened. At this time, the grooves 13 of each protrusion 12 engage with the upper edges 3, 3 of the slit 2 (see FIG. 3), thereby reinforcing the strength of the mounting pieces 5, 5. Further, the lower half of the leg portion 11 enters into the casting resin 9, and is integrally fixed to the case 1 as the resin 9 hardens (see FIG. 2).
