Abstract

The invention discloses a circuit board shielding protective cover body easy to disassemble and maintain. The circuit board comprises a circuit board body, a first sliding block, a rotating screw rod,a fixed shaft and a clamping block, the circuit board body is attached to a bottom plate, a heat dissipation plate is installed on the bottom plate, the bottom plate is connected with a heat insulation plate, a first sliding block is attached to the bottom plate, the bottom plate is installed on a moving plate, the moving plate is connected with a positioning block, a rotating screw is connectedwith the first sliding block, and the rotating screw is connected with a protective cover body. The invention discloses a circuit board shielding protective cover body easy to disassemble and maintain. The heat dissipation plate is made of an aluminum alloy material; the heat insulation plate is arranged to be made of the aerogel felt material so that the temperature of other parts can be effectively prevented from being transmitted to the circuit board body, the circuit board body can be protected, and the protection cover body and the bottom plate can be assembled and disassembled by rotating the rotating rod. The heat insulation plate is arranged to be made of the aerogel felt material so that heat dissipation of the circuit board body can be effectively accelerated.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board shielding and protection cover that is easy to disassemble and maintain. Background technique [0002] Circuit boards are mainly used in electronic equipment. According to the number of layers, circuit boards are usually divided into single-sided, double-sided and multi-layer boards. Therefore, different types of circuit boards can be selected for use according to different needs. In order to make circuit boards in use In order to avoid the influence of external electromagnetic waves on the internal circuit and the external radiation of electromagnetic waves generated inside, it is usually necessary to use a shielding cover to protect the circuit board. [0003] However, there are also some problems in the process of using the shielding protective cover. For example, the common cover is usually set in the form of integration with the circuit board, which is...
