Description

Technical Field

[0001] This utility model relates to the field of security circuit boards, specifically a new type of security circuit board. Background Technology

[0002] As a core component of security systems, security circuit boards integrate functions such as video acquisition, data processing, signal transmission, and intelligent analysis. They are widely used in fields such as surveillance cameras, alarm systems, and access control. They emphasize high stability, anti-interference capabilities, and environmental adaptability, adopt a modular structure for easy maintenance and upgrades, and support AI algorithms and edge computing to improve real-time performance.

[0003] Current circuit boards contain several different types of components. In actual use, there is a problem: the components on the circuit board are mainly divided into high-frequency and low-frequency circuit areas. Crosstalk occurs during use, affecting the normal use of the circuit board. In view of this, the inventor urgently needs to design a protective mechanism that can reduce crosstalk, thereby improving the ease of use and protection of the circuit board. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a new type of security circuit board to solve the technical problem of crosstalk between high-frequency and low-frequency circuit regions in the circuit board.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel security circuit board, comprising a circuit board body, wherein sliding grooves are provided on both sides of the circuit board body, and a spacer plate is slidably mounted on the circuit board body through the sliding grooves and elastic components, the spacer plate being used to separate high frequency areas and low frequency areas, the spacer plate being longitudinally adjustable through the elastic components, and the bottom end of the spacer plate abutting against the surface of the circuit board body through the elastic components.

[0006] By adopting the above technical solution, grooves are set on both sides of the main body of the circuit board and spacers are slidably installed with elastic components, achieving dynamic physical isolation between the high-frequency and low-frequency regions. This allows the position of the spacers to be adjusted longitudinally according to the actual circuit layout requirements, flexibly adapting to the distribution of different functional modules and avoiding compatibility issues caused by layout limitations in traditional fixed isolation structures.

[0007] Furthermore, the spacer is a copper alloy metal sheet, and the spacer can have two, but not limited to, two bending morphological features.

[0008] By adopting the above technical solution, the spacer plate is made of copper alloy metal plate, whose high conductivity and magnetic permeability can form an effective electromagnetic shielding layer, blocking the radiation interference of high frequency signals to the low frequency region. It works in synergy with the copper alloy slide rail in the chute to further enhance the overall grounding effect.

[0009] Furthermore, the pressing surface of the spacer plate against the main body of the circuit board does not conflict with the position of the electrical components, and the spacer plate is made of 0.5-1mm thick material.

[0010] By adopting the above technical solution, the pressure surfaces of the spacer and the main body of the circuit board avoid the positions of electrical components, ensuring that there is no risk of mechanical compression or short circuit to the components on the board during adjustment or fixing. This is especially suitable for the protection needs of complex components in high-density circuit boards.

[0011] Furthermore, the elastic component includes a mounting plate, the bottom end of which engages and slides with the slide groove and is positioned by bolts, and a thin slide rail made of copper alloy is provided on the inner side of the slide groove.

[0012] By adopting the above technical solution, the interlocking and sliding design of the mounting plate and the slide groove, combined with the bolt abutment positioning, enables the quick installation, disassembly and position locking of the partition plate, which facilitates later maintenance or layout adjustment and reduces the complexity of operation.

[0013] Furthermore, the mounting plate is provided with an adjustment groove, and a slider is engaged and slidable on the inner side of the adjustment groove. A mounting block is installed on the top of the mounting plate by bolts, and the mounting block is used to close the upper opening of the adjustment groove.

[0014] By adopting the above technical solution, the locking and sliding design of the adjustment groove and the slider allows the spacer to slide in the longitudinal direction, further adapting to the unrestricted sliding process of the spacer, such as avoiding heat sinks or connectors in specific areas, and enhancing the accuracy of shielding coverage.

[0015] Furthermore, a sleeve is fixedly installed above the slider, and a sleeve rod is sleeved on the upper inner side of the sleeve, with the top end of the sleeve rod being fixedly connected to the mounting block.

[0016] By adopting the above technical solution, the nested structure of the sleeve and the sleeve rod, together with the elastic element, provides a continuous and uniform elastic abutment force for the spacer plate, ensuring that the bottom end of the spacer plate is tightly attached to the surface of the circuit board body and maintaining the shielding effectiveness.

[0017] Furthermore, an elastic element is elastically installed on the inner side of the sleeve to provide a contact force between the spacer plate and the circuit board body, and mounting holes are provided at the four corners of the circuit board body.

[0018] By adopting the above technical solution, the elastic installation of the elastic element provides the spacer with adaptive abutment force, enabling it to dynamically adjust the downward pressure according to the actual height of the components on the surface of the circuit board. For example, it can automatically retract and avoid protruding components, while maintaining full contact in flat areas, thus taking into account both shielding effect and component protection requirements.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model achieves lateral position adjustment of the spacer plate by combining the sliding grooves on both sides of the circuit board body with the elastic components. It can dynamically adjust the isolation range according to the actual distribution of high frequency and low frequency regions, adapt to different circuit layout requirements, reduce signal crosstalk, and at the same time, the spacer plate is made of copper alloy and bent into various shapes. It can block electromagnetic interference through the metal shielding characteristics, avoid the protruding components on the surface of the circuit board body, avoid mechanical interference, and improve compatibility.

[0021] 2. In this utility model, during the lateral sliding of the partition plate, the elastic force of the elastic element is overcome by the lifting action, causing the sliders on both sides of the partition plate to move upward along the adjustment groove, thereby forcibly increasing the distance between the partition plate and the main body of the circuit board. This operation directly avoids mechanical collision or friction between the bottom of the partition plate and the protruding electrical components on the surface of the main body of the circuit board. Especially in areas with dense components, it can prevent scratching of components or causing short circuit risks, thus ensuring circuit safety. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In this embodiment:

[0030] A new type of security circuit board, such as Figure 1-5 As shown, the circuit includes a circuit board body 1 with grooves 3 on both sides. A spacer 2 is slidably mounted on the circuit board body 1 via the grooves 3 and elastic components 4. The spacer 2 is used to separate the high-frequency region from the low-frequency region. The spacer 2 is longitudinally adjustable via the elastic components 4, and the bottom end of the spacer 2 abuts against the surface of the circuit board body 1 via the elastic components 4. The grooves 3 on both sides of the circuit board body 1 and the spacer 2 slidably mounted with the elastic components 4 achieve dynamic physical isolation between the high-frequency region and the low-frequency region. This allows the position of the spacer 2 to be adjusted longitudinally according to the actual circuit layout requirements, flexibly adapting to the distribution of different functional modules. This avoids compatibility issues caused by layout limitations in traditional fixed isolation structures. At the same time, the spacer 2 elastically abuts against the surface of the circuit board body 1 via the bottom end of the elastic components 4, ensuring the stability of the shielding structure and adapting to minor undulations or vibrations on the circuit board surface through elastic pressure. This reduces the risk of shielding failure caused by mechanical loosening, thereby effectively suppressing electromagnetic crosstalk between high and low frequency signals and improving the reliability of circuit operation.

[0031] See Figure 1 , Figure 2 The spacer 2 is a copper alloy metal plate. The spacer 2 has two, but not limited to, two bending morphology features. The spacer 2 is made of copper alloy metal plate. Its high conductivity and magnetic permeability can form an effective electromagnetic shielding layer to block the radiation interference of high frequency signals to the low frequency region. It works in conjunction with the copper alloy slide rail in the slide groove 3 to further enhance the overall grounding effect. At the same time, the spacer 2 supports at least two bending morphologies and can be adapted to the actual distribution of high frequency and low frequency devices on the main body of the circuit board 1.

[0032] See Figure 1 , Figure 2 The pressure surfaces of the spacer 2 and the main body of the circuit board 1 do not conflict with the positions of the electrical components. The spacer 2 is made of 0.5-1mm thick material. The pressure surfaces of the spacer 2 and the main body of the circuit board 1 avoid the positions of the electrical components, ensuring that there is no risk of mechanical compression or short circuit to the components on the board during adjustment or fixing. It is especially suitable for the protection needs of complex components in high-density circuit boards. At the same time, the spacer 2 is made of 0.5-1mm thick material, which takes into account the requirements of structural strength and lightweight. It can withstand the pressure applied by the elastic component 4 to maintain the shielding stability, while avoiding the increase of the overall weight of the circuit board or the occupation of too much space due to excessively thick material. It is in line with the development trend of miniaturization and integration of security equipment.

[0033] See Figure 1 , Figure 3 , Figure 4 , Figure 5The elastic component 4 includes a mounting plate 401. The bottom end of the mounting plate 401 engages and slides with the slide groove 3, and is positioned by abutting with bolts 407. A thin slide rail made of copper alloy is provided on the inner side of the slide groove 3. The engagement and sliding design of the mounting plate 401 and the slide groove 3, combined with the abutting and positioning of the bolts 407, realizes the quick installation, disassembly and position locking of the partition plate 2, which facilitates later maintenance or layout adjustment and reduces the complexity of operation. At the same time, the copper alloy slide rail on the inner side of the slide groove 3 is connected to the grounding layer of the circuit board body 1, which not only provides a low impedance grounding path for the partition plate 2 to optimize the electromagnetic shielding effect, but also improves the smoothness of sliding adjustment through the guiding effect of the slide rail, avoids positioning deviation caused by frictional resistance, and ensures the long-term reliability of the shielding structure.

[0034] See Figure 1 , Figure 3 , Figure 4 , Figure 5 The mounting plate 401 has an adjustment groove 402, and a slider 403 is engaged and slidable inside the adjustment groove 402. A mounting block 408 is bolted to the top of the mounting plate 401, and the mounting block 408 is used to close the upper opening of the adjustment groove 402. The engagement and sliding design of the adjustment groove 402 and the slider 403 allows the spacer 2 to slide longitudinally, further adapting to the unrestricted sliding process of the spacer 2, such as avoiding heat sinks or connectors in specific areas, thus enhancing the accuracy of shielding coverage. Simultaneously, by closing the upper opening of the adjustment groove 402 with the mounting block 408, it prevents external foreign objects from entering the slide groove 3 and affecting the operation of the sliding mechanism, and also enhances the connection strength between the mounting plate 401 and the slide groove 3 through bolt fixing, preventing component loosening due to vibration or external impact, and maintaining the overall stability of the shielding structure.

[0035] See Figure 1 , Figure 3 , Figure 4 , Figure 5 A sleeve 405 is fixedly installed above the slider 403. A sleeve rod 404 is sleeved on the upper inner side of the sleeve 405. The top end of the sleeve rod 404 is fixedly connected to the mounting block 408. The nested structure of the sleeve 405 and the sleeve rod 404, together with the elastic element 406, provides a continuous and uniform elastic abutment force for the spacer plate 2, ensuring that the bottom end of the spacer plate 2 is tightly attached to the surface of the circuit board body 1, maintaining the shielding effectiveness. At the same time, the fixed connection between the top end of the sleeve rod 404 and the mounting block 408 limits the movement range of the sleeve 405, preventing the elastic element 406 from being over-compressed or rebounding, causing the spacer plate 2 to shift position, and ensuring the positional stability of the adjusted shielding structure.

[0036] See Figure 4 , Figure 5The inner side of the sleeve 405 is elastically fitted with an elastic element 406, which provides the spacer 2 with the contact force between it and the circuit board body 1. Mounting holes 5 are provided at the four corners of the circuit board body 1. The elastic installation of the elastic element 406 provides the spacer 2 with an adaptive contact force, which can dynamically adjust the downward pressure according to the actual height of the components on the surface of the circuit board body 1. For example, it can automatically retract and avoid protruding components, while maintaining full contact in flat areas, taking into account both the shielding effect and the component protection requirements. At the same time, the mounting holes 5 at the four corners of the circuit board body 1 provide a standardized fixing interface for the entire circuit board, which facilitates quick assembly with the equipment shell or other functional modules. This simplifies the installation process and enhances the structural stability of the circuit board in complex environments through multi-point fixing, thereby improving the long-term operational reliability of the security equipment.

[0037] The implementation principle of this embodiment is as follows: The circuit board body 1 has sliding grooves 3 on both sides. An elastic component 4, slidably installed within the sliding grooves 3, drives the spacer 2 to adjust its position laterally. The spacer 2 separates the high-frequency and low-frequency regions on the circuit board, thereby reducing crosstalk. It is then fixed with bolts 407. During the lateral sliding of the spacer 2, by lifting the spacer 2 and overcoming the elastic force of the elastic component 406, the two sides of the spacer 2 slide through the slider 403 and the adjusting groove 402, gradually increasing the distance between the spacer 2 and the circuit board body 1, ensuring the lateral sliding of the spacer 2. During the process, it does not conflict with the electrical components on the surface of the circuit board body 1. The spacer plate 2 is made of copper alloy and can be bent to adapt to different circuit layouts. Its bottom end provides adaptive pressure through the sleeve 405 and the elastic element 406 in the sleeve rod 404, so that the spacer plate 2 is stably abutted against the surface of the circuit board body 1, forming a physical isolation barrier in the high and low frequency areas. At the same time, the copper alloy slide rail inside the slide groove 3 is connected to the ground layer of the circuit board body 1, enhancing the electromagnetic shielding effect. The mounting block 408 closes the upper opening of the adjustment groove 402 to ensure the structural stability, while the mounting holes 5 at the four corners of the circuit board body 1 facilitate overall fixation.
