Reference numeral 5 denotes a pressure contact portion provided on the cover 14, which is formed at a position corresponding to the protrusion 13. Electronic components are mounted in the frame 11.

コネクタ１２の直径１２ａの約１．２倍としている。FIG. 2 is a perspective view of a main part in the vicinity of the protruding part 13 and the pressure contact part 15. In FIG. 2, the width 13a of the protrusion 13 is larger than the diameter 12a of the cylindrical connector 12. This is to ensure that the contact with the press contact portion 15 is obtained. In this embodiment, the width 13a of the press contact portion is set to be about 1.2 times the diameter 12a of the connector 12.

The longer the length b is, the more reliable the ground can be taken. However, if the length is too long, it will affect the mounting of electronic components and the like, so the length is preferably 1 mm to 5 mm.

ってカバー１４を枠体１１に装着した時、圧接部１５は
突出部１３に確実に当接することになる。Reference numeral 15 denotes a pressure contact portion formed integrally with the cover 14, which is formed by a slit 16 and a slit 17 (three or more slits may be provided). The length 16a of the slit 16 and the slit 1
The length 17a of the projection 7 is the bending length 13b of the projection 13.
Shorter than the length. This is because the holes formed by the slits 16 and 17 are surely closed by the projections 13 when the cover 14 is mounted. As the length of the slit 16 and the slit 17 is longer, the elasticity of the press contact portion 15 is increased, and the contact becomes stable. However, since the holes of the slits 16 and 17 cannot be closed by the protruding portions 13, the shielding effect deteriorates. Therefore, in this embodiment, the length of the slit 16 and the slit 17 is set to about 2.5 mm so that the slit 16 and the slit 17 do not form a hole. In addition, the pressure contact portion 15 formed between the slit 16 and the slit 17 has a tip portion downward, that is, 0.5 mm to 1.0 mm toward the contact portion 13 side.
As shown in the figure, the pressing portion 15 is bent at the base 15b. Therefore, when the cover 14 is mounted on the frame 11, the press contact portion 15 reliably comes into contact with the protrusion 13.

望ましい。Next, the pressing width 15a of the pressing portion 15 will be described with reference to FIG. When the width 15a of the press-contact portion is reduced, the gap 18 between the cover 14 and the frame 11 increases as shown in FIG. Further, as shown in FIG. 3A, when the press contact width 15a is increased, the gap 18 is reduced, and the shielding effect between the frame body 11 and the cover 14a is improved, but the fitting is deteriorated. Therefore, in this embodiment, the pressure contact width 15a is set to about half of the diameter 12a of the connector 12. The pressure contact width 15a is desirably about 1/4 to 2/3 of the diameter 12a of the connector 12.

From the tip 21a of the press contact portion 21 to the root 21b.
This is an example in which is narrowed.

２４ｂを狭くした例である。FIG. 4B shows the slit 22 and the slit 2.
3 is an example in which the base portion 24b is formed obliquely and the root portion 24b is narrower than the tip portion 24a of the press contact portion 24.

がより安定する。By adopting such a shape, the distal ends 21a and 24a are widened, so that the projections 13 can be reliably brought into contact. Further, since the base is narrow, the elastic effect at the time of pressing is greater, and the contact with the protruding portion 13 is more stable.
