Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically a modular circuit board that can quickly repair circuits. Background Technology

[0002] With the advancement of technology, electronic products are constantly evolving towards miniaturization and multifunctionality, placing higher demands on circuit board design. To adapt to the needs of different application scenarios, modular design concepts have gradually been introduced into circuit board design. This design philosophy not only helps improve production efficiency but also enables flexible combinations of components through standardized interfaces, making product upgrades more convenient.

[0003] In practical applications, if a module on an existing circuit board fails, the entire module or the entire circuit board often needs to be replaced. This not only increases maintenance costs but may also lead to prolonged downtime. Furthermore, due to the tight connections between modules, the disassembly and reinstallation process is complex and prone to secondary damage or poor contact, further affecting the stability and reliability of the system. Therefore, existing circuit boards lack a simple and efficient method for rapid repair when faced with local circuit faults, which affects the continuous operation of electronic equipment. Utility Model Content

[0004] The purpose of this invention is to provide a modular circuit board that can quickly repair circuits, thereby solving the problems mentioned in the background art, such as high repair costs, complex processes, and easy secondary damage when circuit boards have local circuit faults.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular circuit board for rapid circuit repair, comprising a main frame, several modular units detachably mounted on the top of the main frame, several standardized sockets on the top of the main frame, each standardized socket having an elastic contact piece and a positioning element inside to ensure precise alignment and stable connection when the modular unit is inserted, the bottom of each modular unit having a plug that matches the standardized socket, the plug having a metal contact point that mates with the elastic contact piece and a guide groove corresponding to the positioning element, and the edges of the four corners of the main frame having reinforced borders.

[0006] Preferably, the positioning element has a trapezoidal block structure with its narrower side facing outwards, and the outer wall of the positioning element is provided with anti-slip texture.

[0007] Preferably, the elastic contact sheet is made of a multilayer composite material, and the inner and outer layers of the elastic contact sheet are respectively a metal layer with excellent conductivity and a rubber layer with high elasticity.

[0008] Preferably, a sealing ring is provided at the connection between the insert and the module unit, and the thickness of the sealing ring is 1-3 mm.

[0009] Preferably, the reinforced frame is made of high-strength alloy material, and the outer wall of the reinforced frame is provided with a plurality of reinforcing ribs, and the corner of the outer wall of the reinforced frame is provided with an arc transition area.

[0010] Preferably, the elastic contact pieces are symmetrically arranged on the inner walls of the front and rear sides of the standardized socket, and the positioning elements are symmetrically arranged on the inner walls of the left and right sides of the standardized socket.

[0011] Compared with existing technologies, the advantages of this invention are as follows: The modular circuit board for quick-repair circuitry employs easily detachable small modular units and flexible contact connections, significantly simplifying the repair process, reducing maintenance costs, minimizing the risk of secondary damage caused by disassembly and reinstallation, and simultaneously improving system stability and reliability. The modular circuit board for quick-repair circuitry, through the design of flexible contact pieces and positioning elements within standardized sockets, ensures precise alignment and secure connection when inserting modular units.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a modular circuit board for rapid circuit repair, comprising a main frame 1, with several module units 2 detachably mounted on the top of the main frame 1, and several standardized sockets 3 on the top of the main frame 1. Each standardized socket 3 has an elastic contact piece 301 and a positioning element 302 inside. The elastic contact pieces 301 are symmetrically arranged on the inner walls of the front and rear sides of the standardized socket 3, and the positioning elements 302 are symmetrically arranged on the inner walls of the left and right sides of the standardized socket 3, to ensure precise alignment and stable connection when the module unit 2 is inserted. The bottom of the module unit 2 has a plug 4 that matches the standardized socket 3, and the plug 4 has a metal contact 401 that mates with the elastic contact piece 301 and a corresponding metal contact 402 that mates with the positioning element 302. The guide groove 402 and the reinforced frame 5 at each of the four corners of the main frame 1 allow the user to easily insert the plug 4 at the bottom of the module unit 2 into the standardized socket 3 when it needs to be replaced or repaired. The plug 4 slides into the positioning part 302 through the guide groove 402 for positioning. Simultaneously, the metal contact 401 on the plug 4 contacts the elastic contact piece 301 inside the standardized socket 3, forming a stable electrical connection. This not only ensures precise alignment of the module unit 2 during insertion but also enables plug-and-play functionality, allowing for module installation and removal without special tools. Furthermore, the reinforced frame 5 at the four corners of the main frame 1 enhances the overall structural stability and prevents deformation caused by external forces. The circuit board may become loose, allowing for a simple and quick solution to localized circuit faults by replacing the faulty module unit 2. This avoids the high costs and long downtime associated with traditional methods that require replacing the entire module or circuit board. Furthermore, the looser connections between module units 2 simplify disassembly and reinstallation, significantly reducing the risk of secondary damage and poor contact, thus improving system stability and reliability. The positioning component 302 has a trapezoidal block structure with its narrower side facing outwards, and its outer wall has anti-slip textures. This structure allows the insertion block 4 at the bottom of the module unit 2 to slide along the positioning component 3 when inserted into the standardized socket 3. The inclined surface of 02 slides in easily, and precise guidance and positioning are achieved through the guide groove 402. The synergistic effect of the trapezoidal structure and anti-slip texture of the positioning element 302 ensures the smoothness and accuracy of module unit 2 insertion, while providing a stable mechanical lock to prevent the module from loosening or falling off due to vibration or other external forces during use. The elastic contact piece 301 is made of multi-layer composite material, with its inner and outer layers being a metal layer with excellent conductivity and a rubber layer with high elasticity, respectively. This structure provides excellent conductivity to the metal layer of the elastic contact piece 301, ensuring efficient and stable signal transmission, while the rubber layer gives it sufficient elasticity, allowing it to automatically adjust pressure during insertion and removal.To ensure good contact and prevent poor contact or loosening due to prolonged use, a sealing ring 403 with a thickness of 1-3mm surrounds the connection between the plug 4 and the module unit 2. When the plug 4 is inserted into the standardized socket 3, the sealing ring 403 fits tightly against the top surface of the standardized socket 3, forming an effective waterproof and dustproof barrier. This prevents external contaminants such as dust and moisture from entering the connection area between the module unit 2 and the main frame 1. The reinforcing frame 5 is made of high-strength alloy material, and its outer wall has several reinforcing ribs 501. Furthermore, the corners of the outer wall of the reinforcing frame 5 have rounded transition areas. This structure not only provides robust edge protection for the circuit board, preventing deformation or damage caused by external impacts or improper operation, but also further enhances the rigidity of the frame through the reinforcing ribs 501, effectively dispersing the pressure that may be applied to the main frame 1. The rounded transition area design reduces stress concentration and avoids cracks or breaks that are prone to occur at the corners.

[0018] Working Principle: When using this modular circuit board for quick circuit repair, the user first aligns the insert 4 at the bottom of the module unit 2 with the standardized socket 3 at the top of the main frame 1, and easily slides it in along the inclined surface of the positioning member 302. As the insert 4 gradually penetrates, the guide groove 402 and the outside of the positioning member 302 fit tightly, ensuring precise alignment of the module unit 2 during insertion. At the same time, the metal contact 401 on the insert 4 contacts the elastic contact piece 301 inside the standardized socket 3, forming a stable electrical connection. When the insert 4 is fully inserted into the standardized socket 3, the sealing ring 403 can tightly... The inner wall of the standardized socket 3 is fitted to provide effective waterproof and dustproof protection. Next, the user can complete the installation or removal of the module unit 2 without special tools, realizing the plug-and-play function. During the insertion and removal process, the elastic contact piece 301 automatically adjusts the pressure with the rubber layer in its multi-layer composite material structure to ensure good contact performance. The reinforced frame 5 provides additional mechanical support for the entire circuit board to prevent deformation or loosening caused by external forces, especially at the four corner edges, to ensure the stability and reliability of the circuit board in various environments, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
