Description

Technical Field

[0001] This utility model relates to the field of printed circuit board technology, specifically to an anti-static protection structure for printed circuit boards. Background Technology

[0002] Circuit boards, also known as printed circuit boards or PCBs, provide assembly support and electrical connections for various electronic systems, earning them the title of "mother of electronic products." Currently, PCBs are widely used in the electronics manufacturing industry and are an important component of the electronics and information industry. They are formed by etching copper foil covering an insulating substrate into conductive lines that meet the connection requirements of electronic components using electronic printing techniques. Circuit boards are mainly classified into the following types: communication boards, automotive boards, flexible printed circuit boards (FPCBs), and HDI boards, etc.

[0003] During use, printed circuit boards (PCBs) have poor heat dissipation and require additional cooling solutions to optimize their performance. Additionally, PCBs generate static electricity during operation. When this static electricity accumulates to a certain level, it discharges, which can cause device breakdown.

[0004] Therefore, we propose an anti-static protection structure for printed circuit boards. Utility Model Content

[0005] The purpose of this invention is to provide an anti-static protection structure for printed circuit boards to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-static protection structure for a printed circuit board, comprising a mounting plate, a housing, fixing bolts, and a mounting groove, wherein the housing is mounted on the top surface of the mounting plate, fixing bolts are mounted at all four ends of the top surface of the mounting plate, and a mounting groove is formed at the center of the top surface of the mounting plate.

[0007] Preferably, a combination frame is sequentially installed on the top surface of the housing, and combination blocks are symmetrically installed on both sides of the housing. Magnetic sheets are installed on the bottom surface of the combination blocks and inside the combination frame.

[0008] Preferably, a cover plate is installed inside the housing, and a limiting plate is installed in sequence inside the housing. A limiting spring is installed on the top surface of the limiting plate, and the top surface of the limiting spring is connected to the cover plate. A heat dissipation copper sheet is installed in sequence on the top surface of the cover plate, and conductive copper sheets are symmetrically installed inside the heat dissipation copper sheet.

[0009] Preferably, capacitors are symmetrically installed on both sides of the cover plate, and both ends of the conductive copper sheet are connected to the capacitors. A conductive wire is installed at the bottom of the capacitor, and a conductive hole is provided at the connection between the conductive wire and the mounting plate.

[0010] Preferably, the top surface of the cover plate is symmetrically provided with connecting grooves, a connecting spring is installed inside the connecting groove, a connecting block is fixedly connected to one end of the connecting spring, and connecting holes are provided on the surfaces of the housing at the connecting blocks on both sides.

[0011] Preferably, a fixing block is installed on the outer surface of the housing at the connection hole, and a push rod is slidably installed inside the fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a combination of heat dissipation copper sheet and conductive copper sheet, when the cover plate is pressed, the cover plate moves downward, causing the heat dissipation copper sheet to move downward as well. When the heat dissipation copper sheet comes into contact with the printed circuit board, the good thermal conductivity of the copper sheet can be used to dissipate heat from the heat dissipation copper sheet. At the same time, when the heat dissipation copper sheet moves downward, it causes the conductive copper sheet to move downward as well, so that the two ends of the conductive copper sheet come into contact with the capacitor. The good conductivity of the copper sheet can be used to transfer static electricity to the capacitor through the conductive copper sheet, and then discharge it to the ground through the conductive wire. By using the connecting springs and connecting blocks symmetrically installed on both sides of the cover plate, when the cover plate moves downward, the connecting blocks can be installed into the connecting holes through the connecting springs to connect the cover plate to the housing.
