9を一体に有する裏蓋10が組合わされる。 FIGS. 1 and 2 show an example of a conventional noise filter of this type. In these figures, insulating resin terminal plates 4 having grooves 3 that fit into the notches 2 are fitted into the notches 2 on both sides of the metal case 1, and metal terminals 5 are fitted into the terminal plates 4. is fixed. A common mode choke coil 6 and a capacitor 7 are housed inside the metal case 1, and predetermined wiring and connections are made. A back cover 10 integrally having a mounting portion 9 in which a mounting hole 8 is formed is attached to the opening of the metal case 1.

らない。 By the way, in the conventional structure as described above, it is necessary to provide the notch 2 in the part of the metal case 1 where the terminal plate 4 is placed, and therefore the mounting part 9 must be provided in the back cover 10. , it is not possible to adopt a structure in which the back cover 10 is omitted. For this reason, there is a drawback that the number of parts increases and the assembly work becomes troublesome. Further, there are cases where it is desired to provide the metal case 1 insulated from the chassis of the attached equipment, but in such a case, an insulating bushing or the like must be prepared separately.
本考案は、上記の点に鑑み、金属ケースに嵌着

ようとするものである。 In view of the above points, the present invention provides an L-shaped structure for the insulating resin terminal plate that is fitted into the metal case with an integral mounting part, thereby making it possible to omit the back cover and reducing the number of parts. Another object of the present invention is to provide a noise filter that can be easily assembled and installed with a metal case insulated from the equipment on which it is installed.
以下、本考案に係るノイズフイルタの実施例を
図面に従つて説明する。 Embodiments of the noise filter according to the present invention will be described below with reference to the drawings.

る。 FIG. 3 shows a first embodiment of the present invention. In this figure, resin terminal plates 4A are provided in the notches 2 on both sides of the metal case 1, and are bent into an L-shape so as to integrally have a mounting portion 9A. That is, as shown in FIG. 4, grooves 3 that fit into the notches 2 are formed on both end surfaces of the terminal plate 4A, and the terminal plate 4A is fixed in the metal case 1 in a fitted state. A mounting hole 8A is formed in the mounting portion 9A of such a terminal board 4A. A common mode choke coil 6, a capacitor 7, etc. are housed in the metal case 1, and after predetermined wiring is connected to the metal terminals 5, etc., the inside of the case is molded with an insulating resin 20.

る場合がある。 According to the first embodiment, the insulating resin terminal plate 4
Since A is bent into an L-shape and integrally has the mounting portion 9A, the mounting portion 9A can be used to fix the device to the chassis of the device to be mounted. For this reason, the back cover of the conventional case is unnecessary,
The number of parts can be reduced and the number of assembly steps can also be reduced. Further, since the metal case 1 can be electrically insulated from the chassis of the other device, this may be particularly advantageous depending on the installation location.

1実施例と同様である。 FIG. 5 shows a second embodiment of the invention. In this case, the metal case 1B has the notch 2 formed only on one side, and the metal case 1B has a mounting part 9B integrally formed with the mounting hole 8B on the other side. Then, the insulating resin terminal plate 4B is fitted into the notch 2. The terminal plate 4B in this case is bent into an L-shape like the terminal plate 4A in the first embodiment, and has the mounting hole 8.
Although it has an integral mounting portion 9C formed with C, as many metal terminals 5 as necessary are provided. Note that the other structures are the same as those of the first embodiment described above.
