Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that it is difficult to shield part of the signal units of the PCB board, resulting in electromagnetic signal interference affecting the normal use of the circuit board, and the poor grounding of the PCB signal unit, which is prone to ground faults and burnout of electrical components. A shielding and grounding device for a PCB signal unit, the shielding and grounding device realizes the grounding of the PCB signal unit while completing the shielding of the PCB signal unit by setting a shielding cover that covers the PCB signal unit, and arranging a connecting piece on the shielding cover. Thereby solving the problem of poor grounding and mutual interference of the PCB signal unit in the prior art, ensuring good grounding of the PCB signal unit, and achieving a good shielding effect, ensuring the normal use of the PCB signal unit and the circuit board, and achieving good use Function

Embodiment

[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 ...

Abstract

The invention belongs to the technical field of electrical equipment and particularly relates to a PCB (printed circuit board) signal unit shield grounding device. The PCB signal unit shield groundingdevice comprises a shielding case used for shielding PCB signal units, connecting pieces are arranged on the outer side of the shielding case, and after the PCB signal units are shielded by the shielding case, the connecting pieces contact with the inner wall of a cabinet shell provided with a PCB. The shielding case used for shielding the PCB signal units is arranged, the connecting pieces are arranged on the shielding case, and the PCB signal units are shielded and grounded, so that problems that PCB signal units are grounded badly leading to mutual interference in the prior art are solved,the PCB signal units are assuredly well grounded, good shielding effect is achieved, normal use of the PCB signal units and the PCB is guaranteed, and good use functions are achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a shielding and grounding device for a PCB signal unit. Background technique [0002] As an important electronic component, the PCB board is the support of electronic components and the carrier of electrical connections. Electronic components are installed on the PCB to perform specific functions, such as computer motherboards, communication equipment circuit boards, and signal transmission and reception. circuit board etc. The PCB board installed with electronic components functions as an overall structure, but it essentially includes a plurality of different signal units, and each signal unit is installed in a different area of ​​the PCB board and performs different functions. [0003] During the use of the PCB board, it is usually installed in the chassis shell for use. During the use process, the main problems are: ①. Each signal unit will emit its own electroma...
