欠点があつた。 Conventionally, in audio equipment, in order to prevent external noise from being induced into the circuit, a shield plate made of metal foil or plastic film coated with a conductive film is glued to the case, and a lead wire is soldered to the ground of the printed circuit board or the ground terminal. It was connected.
However, with this mounting method, if the case is mounted without sufficient adhesion, it may peel off during the process and cause a short circuit, or if the case surface and shield plate surface to be bonded are dirty, the adhesive strength may not be sufficient. It may not be obtained and it may peel off before you know it.
It is necessary to clean the adhesive surface beforehand. In addition, it is necessary to connect the lead wire and perform ground wiring, which has the disadvantage of complicating the installation work and increasing manufacturing costs.
そこで本考案ではこれらの欠点を解決するもの

As is clearer, the hollow hole 3 has large diameter holes 3a and 3a.
Consisting of a smaller diameter hole 3b, 3a, 3b
A step 3c is provided at the joint of the
c is connected to the insertion hole 4. In the embodiment, the insertion hole 4 uses the inner surface of the case 1, but it may also have a shape in which a part of the side wall 2A of the boss 2 is cut out. Next, the installation of the shield plate using this boss 2 will be explained. As shown in Fig. 3, the shield plate 5
Insert the end of the boss 2 through the insertion hole 4, and step 3c.
A shield plate 5 is placed at. Note that a hole for passing a metal screw is provided in a portion of the shield plate 5 corresponding to the hollow hole 3. Next, align the boss 2 with the mounting boss 5 provided on the chassis 6 inside the device by sandwiching the printed wiring board 8, insert the metal screw 9 into the hollow hole 3 from the case surface, and insert the metal screw 9 into the screw hole 7a of the boss 7. Fasten with screws. Therefore, the case 1, the shield plate 5, the printed wiring board 8, and the chassis 6 are screwed together, and the through holes 8a of the screws 9 of the printed wiring board 8 are processed as through holes and connected to the ground pattern of the printed wiring board 8. By this, the shield plate 5
Since it is grounded through the screw 9 and the through hole of the through hole 8a, there is no need for the ground connection work by soldering the lead wire as in the conventional case.
