生じ、作業性も悪い。 When a synthetic resin case is used as an exterior case to house the noise reduction element of a coil or capacitor, conventional structures that use insert molding, screws, or rivets to secure metal mounting terminals to the case are difficult. was being considered. However, with insert molding, the mounting terminals are buried during case molding, which increases the thickness of the case, which is disadvantageous in terms of shape and cost. Furthermore, in a structure that is fastened with screws or rivets, the ends of the screws or rivets protrude to the outer surface of the case, causing inconvenience in mounting the noise filter and poor workability.

しようとするものである。 The present invention eliminates the above-mentioned disadvantages and enables mass production by making it possible to easily and securely fix metal mounting terminals to the case when molding the inside of a synthetic resin case that houses the noise reduction element of a coil or capacitor. It is an attempt to provide an excellent and practical noise filter.
以下、本考案に係るノイズフイルタの実施例を

３の外側面Ｂとを一致させるために設けられてい
る。 In FIGS. 1 to 3, a box-shaped synthetic resin case 3 is used as an exterior case for housing the noise removal elements of the coil 1 and capacitor 2.
A band-shaped groove 4 is formed on the inner surface of the case 3. The case opening side portion of this belt-shaped groove 4 is located at the third
As shown in the figure, a terminal fitting groove portion 7 is formed in which the groove side surface 6 forms an acute angle with respect to the groove bottom surface 5. On the other hand, the metal mounting terminal 8 includes a mounting hole 9, a stepped portion 10, a fitting portion 11 that fits into the terminal fitting groove 7, and a fixing hole 1.
2 and 13, which are integrally formed by press working, and the side edges of the fitting portion 11 form an acute angle.
The stepped portion 10 is provided to align the mounting surface A of the mounting terminal 8 with the outer surface B of the case 3.
そして、ケース３の帯状溝４に取付端子８を差
込み、端子嵌合溝部７に嵌合部１１を嵌合させた
状態にてコイル１及びコンデンサ２をケース３に
収納し、ケース３内にモールド樹脂１４を充填す
ることにより、防水タイプのノイズフイルタがで
き上がる。 Then, the mounting terminal 8 is inserted into the belt-shaped groove 4 of the case 3, and the coil 1 and the capacitor 2 are stored in the case 3 with the fitting part 11 fitted into the terminal fitting groove part 7, and molded into the case 3. By filling the resin 14, a waterproof noise filter is completed.
上記実施例によれば、ケース３の内側に取付端
子８が嵌合保持されているため、モールドの際に
取付端子８を抑えている必要がなく、作業性が極

に防止することができる。 According to the above embodiment, since the mounting terminal 8 is fitted and held inside the case 3, there is no need to hold down the mounting terminal 8 during molding, and workability is extremely good. Also, after molding, the mounting terminal 8
Since the molded resin 14 wraps around into the fixing holes 12 and 13, it is possible to reliably prevent the attachment terminal 8 from coming off or wobbling.
なお、上記実施例ではコイル及びコンデンサの
両者をケース内に収納したがいずれか一方のみで
もよく、さらに素子数を増加させても差支えな
い。 In the above embodiment, both the coil and the capacitor are housed in the case, but only one of them may be used, or the number of elements may be increased.
