[0046] Such as figure 1 and figure 2 As shown, the shielding and grounding device of the PCB signal unit includes a shielding cover 1 for covering the PCB signal unit, and the outer side of the shielding cover 1 is connected with a connecting piece 2. After the shielding cover 1 is covered and closed on the PCB signal unit, the The connecting piece 2 is in contact with the inner wall of the chassis shell 4 where the PCB board 3 is installed.
[0047] Set the shielding cover 1, cover the PCB signal unit through the shielding cover 1, so as to isolate the PCB signal unit from other signal units, prevent electromagnetic signals from interfering with each other, and achieve a shielding effect. At the same time, set the connecting piece 2 on the shielding cover 1 , when the shielding cover 1 covers the PCB signal unit, the connecting piece 2 contacts the inner wall of the chassis shell 4, so as to realize the grounding of the PCB signal unit, thereby better protecting the signal ...
