の背面側から取付孔に圧入される。In FIG. 1, the noise filter case 1 is a box-shaped case made of an insulating material and having a rear opening, and the upper half of the front surface has a step of approximately the thickness dimension of the collar 21 of the inlet 2 between the lower half and the lower half. Is the aspect of. In the upper half of the front surface, a window portion 12 through which the body portion 22 of the inlet 2 can be inserted is formed,
Circular recesses 14 having the required inner and outer diameters and lengths are integrally formed inwardly at the portions corresponding to the left and right flanges 21 of the window 12 as shown in the transverse sectional view in FIG. Is
A collar 21 that juts out to the left and right is integrally formed on the front part of the body portion 22, and an internal thread cylinder 23 provided with an internal thread 24 is
One end face is fixed to the mounting hole of No. 1 with the front face of the collar 21 and the other end side extending from the rear face of the collar 21 in parallel with the body portion 22. Fine irregularities (serrations) are formed on the outer peripheral surface of the female screw cylinder 23 to prevent rotation, and the collar 21
Is press-fitted into the mounting hole from the back side.

る。The case 1 and the inlet 2 having such a structure are assembled in the following manner. Insert the body 22 of the inlet 2 into the window 12 from the outside of the case 1 and insert the female screw cylinder 23 into the circular recess 14 to assemble the inlet 2 into the case 1, and the length of the cylinder 23 is less than 1/2 By attaching a screw (not shown) of the length from the inside of the case 1 to the female screw 24 through the hole at the bottom of the circular recess 14 to attach the back surface of the collar 21 to the outer surface of the case 1,
The inlet 2 can be extremely easily combined and fixed to the case 1 in a state where the tip of the column 23 abuts on the bottom surface of the circular recess 14. Since the front surface of the collar 21 of the inlet 2 is substantially flush with the lower half of the front surface of the case 1, a square window portion corresponding to the outer shape of the body portion 22 and a female screw cylinder 23 are formed on the noise filter mounting surface. It is sufficient to form a through hole facing each other.
The inlet can be firmly attached to the surface to which the noise filter is attached by screwing it on. Since the engaging lateral groove 11 is formed in this embodiment, the above-mentioned screw can be obtained by temporarily mounting the noise filter on the mounting surface of another device by using the spring plate with the engaging claw (not shown). It is easier to screw on. Further, in the inlet 2, the female screw 24 of the female screw cylinder 23 extends to the front surface of the collar 21, as can be seen from FIG. 1, so that the male screw is passed through a hole of another device, for example, a case of an electronic device.
The inlet 2 and the noise filter case 1 can be attached to the electronic device by being screwed into the electronic device 4.
