As shown in the figure, a spring material 3 is provided on the side surface of the front metal fitting 2 of the printed circuit board 1, and when the printed circuit boards 1 are mounted in parallel in the case 4, the adjacent printed circuit boards 1 can be connected to each other via the spring material 3. By electrically contacting the front metal fittings 2, it is possible to shield lateral leakage radio waves, and on the other hand, by fixing the top and bottom of each front metal fitting 2 to the case 4 with screws 5, it can be attached to the case 4. It is grounded to shield radio waves leaking in the vertical direction. However, this method requires two screws to be attached to each printed circuit board, which has the disadvantage of increasing the number of steps during assembly.

As shown in FIG. 1, a large number of printed circuit boards 1
are mounted in parallel in a case 4, each having a front metal fitting 2 attached to its front side, and a spring member 3 protruding from the side surface elastically contacting the front metal fitting 2 of an adjacent printed circuit board. Then,
Each printed circuit board 1 occupies a stable position in the lateral direction, and has complete electrical continuity between them.
ケース４の前面に並列された各前面金具２の上
下縁２ａ，２ｂに沿つて、横方向に延在する一対
の押さえ金具６が設けられ、前面金具２を挟持す

いる。これによつてプリント基板１の上下方向の
位置が保持される。 Along the upper and lower edges 2a, 2b of each front metal fitting 2 arranged in parallel on the front surface of the case 4, a pair of holding metal fittings 6 extending in the lateral direction are provided, and the holding metal fittings 6 are held in place by the screws 5. It is fixed to case 4. As a result, the vertical position of the printed circuit board 1 is maintained.
この押さえ金具６は、第２図に示すように、前

ている。 As shown in FIG. 2, this presser metal fitting 6 has a tube-shaped gasket 8 attached to the presser surface 7 facing the front metal fitting 2 over the entire length.
This packing 8 is made of a material having elasticity and conductivity, such as carbon-containing silicone rubber.

なり、上下方向への電波の漏洩も防止される。 When the presser metal fittings 6 are installed along the upper and lower edges of the front metal fitting 2, if the gaskets 8 are not present, the metal fittings will come into contact with each other, and there will be a large gap between the two, making it impossible to achieve perfect electrical contact. do not have. However, in the case of the present invention, due to the presence of the gasket 8, the gasket 8 deforms in response to minute changes in shape of the presser surface 7 or the upper and lower edges 2a, 2b of the front metal fitting when the presser metal fitting 6 is attached. Ensure perfect contact between fittings 2, 6. Furthermore, since the gasket 8 is electrically conductive, the electrical contact between the metal fittings 2 and 6 is sufficient, and leakage of radio waves in the vertical direction is also prevented.
押さえ金具６に対するパツキン８の取付けは、
例えば第２図と第３図に示すように、押さえ面７

の側面の突起１０を差し込んで固定すればよい。 Attaching the gasket 8 to the presser fitting 6 is as follows:
For example, as shown in FIGS. 2 and 3, the holding surface 7
A through hole 9 is provided at an appropriate location, and a gasket 8 is inserted into the through hole 9.
It can be fixed by inserting the protrusion 10 on the side surface.

As described above, according to the present invention, by adopting a pair of upper and lower holding metal fittings, it is no longer necessary to use two screws for each front metal fitting of each printed circuit board to secure it to the case as in the past. The number of screws required can be significantly reduced compared to In addition, a gasket made of conductive material is attached to the pressing surface of the front metal fitting, allowing close contact with the front metal fitting, making it possible to completely ground the case and preventing leakage of radio waves. .
