Description

Technical Field

[0001] This application belongs to the field of circuit board technology, and in particular relates to a circuit board with a panel that is easy to replace. Background Technology

[0002] A circuit board is a type of circuit board. Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, PCB boards, aluminum substrate boards, and high-frequency boards. Circuit boards need to be encapsulated in a housing and fixed to the housing substrate, mainly by screws. This requires drilling holes in the circuit board, which makes subsequent disassembly and assembly inconvenient.

[0003] Patent CN220359584U discloses a circuit board with easy-to-replace inserts, including a bottom shell, a top shell, and a circuit board body. One end of the circuit board body is provided with an insert structure, which includes a backing plate. An embedded plate is fixed to one side of the backing plate. Multiple inserts are fixed to one end of the circuit board body near the insert structure. Multiple slots are opened on the side of the backing plate away from the embedded plate. The multiple inserts are respectively inserted into the multiple slots. The backing plate is adhered to the end of the circuit board body. A circuit groove is opened on the top surface of the bottom shell.

[0004] The aforementioned patent uses a combination of threaded through holes, threaded holes, and locking screws to fix the top shell to the bottom shell. While this achieves a secure fit, the top shell must be disassembled first when replacing the internal panel. As a result, the top and bottom shells, which are fixed by threads, will be installed and disassembled multiple times with the replacement of the panels. The threads inside the threaded through holes and threaded holes will wear down due to repeated tightening and loosening, which may cause the top and bottom shells to become unstable and require replacement with a new top or bottom shell, resulting in unnecessary losses. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this application is to provide a circuit board with easily replaceable panels, which can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a circuit board with an easily replaceable insert, including a bottom shell, a top shell, a circuit board body, and an insert structure, and further comprising:

[0007] A fixing structure is provided on the bottom shell and the top shell, the fixing structure comprising:

[0008] Locking assembly for securing the top shell to the bottom shell;

[0009] An auxiliary component that connects to the locking component and assists in the installation of the locking component;

[0010] The fixing structure is set at all four corners of the bottom shell and the top shell.

[0011] The circuit board with the aforementioned easy-to-replace panel not only ensures a stable connection between the top and bottom shells but also greatly simplifies the replacement process of the internal panels, thereby avoiding thread wear caused by frequent disassembly and assembly. This application's circuit board includes a bottom shell, a top shell, the circuit board body, and a panel structure, and also features a fixing structure, which mainly consists of two parts. A locking component ensures the top shell is securely fixed to the bottom shell and simplifies the installation and disassembly process. An auxiliary component is closely connected to the locking component, serving as a guide, fastener, and assisted disassembly component. Furthermore, the fixing structure is located at all four corners of the bottom and top shells, enhancing overall stability and ensuring balanced force distribution in all directions.

[0012] Furthermore, the locking component includes;

[0013] A replacement slot is located at the bottom of the bottom shell, and a replacement block is provided inside the replacement slot. The replacement block has a threaded hole.

[0014] The first protrusion is located on the top of the base and has a first through hole inside it. A second through hole extending to the threaded hole is located at the bottom of the first through hole.

[0015] A top groove is provided at the top of the top shell, and a third through hole penetrating the top shell is provided inside it;

[0016] Fastening bolts, with threads located at the ends;

[0017] The threaded end of the fastening bolt passes through the third through hole, the first through hole, and the second through hole in sequence before connecting to the threaded hole.

[0018] A replacement slot is located at the bottom of the base housing, and a replacement block is installed within the slot. The replacement block has a threaded hole for engaging with a fastening bolt to secure the top and bottom housings. It can be replaced when the threads wear out, resulting in low cost and eliminating the need to replace the base housing. A first protrusion is located at the top of the base housing, containing a first through hole. A second through hole is located at the bottom of the first through hole, extending to the threaded hole on the replacement block, providing a path for the fastening bolt. A top recess is located at the top of the top housing, containing a third through hole that aligns with the first through hole on the first protrusion, allowing the fastening bolt to pass through the top housing and into the threaded hole in the base housing. The end of the fastening bolt is threaded, ensuring a tight fit with the threaded hole on the replacement block. When the fastening bolt is tightened, the top housing is securely fixed to the base housing, ensuring the stability of the entire circuit board.

[0019] By using the threaded holes on the replacement block and the fastening bolts, the locking assembly achieves a secure connection between the top and bottom shells, ensuring that the circuit board will not loosen or deform during use. Furthermore, despite the threaded connection, the locking assembly's design simplifies disassembly while preventing damage to the top and bottom shells, thus extending their service life.

[0020] Furthermore: the locking component also includes:

[0021] The second protrusion is located in the top groove, and the top of the third through hole passes through the second protrusion;

[0022] A concealed cover is disposed on and connected to the second protrusion, and a fourth through hole communicating with the third through hole is provided on the concealed cover;

[0023] When the concealed cover is engaged with the second protrusion, the horizontal height of the concealed cover is lower than the horizontal height of the top shell surface.

[0024] The second protrusion is located within the top groove, through which the top of the third through hole can pass. This not only provides a more stable support point for the fastening bolt but also ensures that the bolt remains vertical during tightening, thereby reducing wear caused by angular deviation. The concealed cover is located on and connected to the second protrusion, and has a fourth through hole communicating with the third through hole. This ensures that the fastening bolt can smoothly pass through the concealed cover, the second protrusion, the first protrusion, and the threaded holes on the replacement block, thus securing the top and bottom shells. Simultaneously, when the concealed cover engages with the second protrusion, its horizontal height is lower than the surface level of the top shell. This not only provides protection, preventing wear on the first protrusion after tightening, but also avoids protruding components after installation, thus concealing the components and making the entire circuit board look cleaner and more aesthetically pleasing.

[0025] Furthermore, the inner diameters of the first and third through holes are the same and larger than the diameter of the fastening bolt, and the inner diameters of the third and fourth through holes are the same as the diameter of the fastening bolt.

[0026] The first and third through holes have the same inner diameter, both larger than the diameter of the fastening bolt. This allows the fastening bolt to pass through the through holes without thread contact, thus avoiding wear caused by thread friction. It also ensures the fastening bolt remains perpendicular during tightening, reducing additional wear due to angular deviation. Unlike the first and third through holes, the third and fourth through holes are the initial and final holes through which the fastening bolt passes, respectively. Their inner diameter is the same as the bolt's diameter, acting as a limit to prevent misalignment and ensuring the fastening bolt passes tightly through each through hole and smoothly enters the threaded hole on the replacement block.

[0027] Furthermore, the auxiliary components include:

[0028] A positioning block is located at the bottom of the top shell, and a mating groove is provided at the bottom to enclose the first protrusion;

[0029] A pressure ring is mounted on the outer wall of the fastening bolt;

[0030] A spring is installed inside the first through hole and sleeved on the outside of the fastening bolt;

[0031] After the top cover and bottom cover are installed, the inner wall of the mating groove contacts the outer wall of the first protrusion.

[0032] A positioning block is located at the bottom of the top shell, with a mating groove on its bottom. The shape and size of this groove perfectly match the first protrusion. When the top and bottom shells are installed together, the inner wall of the mating groove will be in close contact with the outer wall of the first protrusion, thus providing guidance and positioning. A pressure ring is located on the outer wall of the fastening bolt. Its annular structure increases the contact area between the bolt and the surrounding structure, and also improves the stability of the bolt during tightening. A spring is located within the first through hole and fitted onto the outer wall of the fastening bolt. When the fastening bolt is tightened, the spring is compressed and stores a certain amount of elastic force. This elastic force not only provides additional preload, enhancing the connection stability between the top and bottom shells, but also assists in disassembly, making the bolt easier to loosen and reducing the time required for disassembly.

[0033] Furthermore, there is a gap between the pressure ring and the inner wall of the first through hole.

[0034] The gap between the pressure ring and the inner wall of the first through hole can significantly reduce the friction between them. During the tightening or loosening of the fastening bolt, the gap allows the pressure ring to have a certain amount of room to move within the first through hole, thereby avoiding friction caused by close contact.

[0035] The beneficial effects of this application are:

[0036] 1. The circuit board of this application not only ensures a stable connection between the top and bottom shells, but also greatly simplifies the replacement process of the internal inserts, thereby avoiding the problem of thread wear caused by frequent disassembly and assembly.

[0037] 2. The inner diameters of the first and third through holes are the same and both larger than the diameter of the fastening bolt, allowing the fastening bolt to pass through the through holes without thread contact, thus avoiding wear caused by thread friction. At the same time, it also ensures that the fastening bolt remains perpendicular during tightening, reducing additional wear caused by angular deviations.

[0038] 3. By setting a spring, when the fastening bolt is tightened, the spring is compressed and stores a certain amount of elastic force. This elastic force not only provides additional preload and enhances the connection stability between the top and bottom shells, but also assists in the disassembly process, making the bolt easier to loosen and reducing the time required for disassembly.

[0046] The following description, in conjunction with the accompanying drawings, details the circuit board with easily replaceable panels provided in this application through specific embodiments and application scenarios.

[0047] Example 1:

[0048] like Figures 1 to 4 As shown, this application embodiment provides a circuit board with an easily replaceable panel, including a bottom shell 100, a top shell 110, a circuit board body, and a panel structure, and further includes:

[0049] The fixing structure is provided on the bottom shell 100 and the top shell 110, and the fixing structure includes:

[0050] Locking component 200 is used to secure the top shell 110 to the bottom shell 100;

[0051] Auxiliary component 300 is connected to locking component 200 and is used to assist in the installation of locking component 200;

[0052] The fixing structure is provided at all four corners of the bottom shell 100 and the top shell 110.

[0053] In some embodiments of this application, such as Figure 1 As shown, the circuit board with the aforementioned easy-to-replace panel not only ensures a stable connection between the top shell 110 and the bottom shell 100, but also greatly simplifies the replacement process of the internal panel, thereby avoiding thread wear caused by frequent disassembly and assembly. The circuit board of this application includes a bottom shell 100, a top shell 110, a circuit board body, and a panel structure, and also includes a fixing structure, which mainly consists of two parts. A locking component 200 ensures that the top shell 110 can be firmly fixed to the bottom shell 100 and simplifies the installation and disassembly process. An auxiliary component 300 is tightly connected to the locking component 200, serving as a guide, fastener, and assisted disassembly component. Simultaneously, the fixing structure is provided at all four corners of the bottom shell 100 and the top shell 110, enhancing overall stability and ensuring balanced force distribution in all directions.

[0054] Example 2:

[0055] This application provides a circuit board with easily replaceable panels. In addition to the above-mentioned technical features, the circuit board with easily replaceable panels in this application also includes the following technical features.

[0056] like Figure 4 As shown, the locking component 200 includes;

[0057] A replacement slot 210 is provided at the bottom of the bottom shell 100. A replacement block 211 is provided inside the replacement slot 210. A threaded hole 212 is provided on the replacement block 211.

[0058] A first protrusion 220 is provided on the top of the base, and a first through hole 221 is provided inside it. A second through hole 222 is provided at the bottom of the first through hole 221, which extends to the threaded hole 212.

[0059] A top groove 230 is provided on the top of the top shell 110, and a third through hole 231 penetrating the top shell 110 is provided inside it;

[0060] Fastening bolt 240, with its thread located at the end;

[0061] Among them, the threaded end of the fastening bolt 240 passes through the third through hole 231, the first through hole 221, and the second through hole 222 in sequence and then connects to the threaded hole 212.

[0062] In this embodiment, a replacement slot 210 is located at the bottom of the bottom shell 100, and a replacement block 211 is installed within the replacement slot 210. The replacement block 211 has a threaded hole 212 for engaging with a fastening bolt 240 to secure the top shell 110 to the bottom shell 100. It can be replaced after the threads wear down, resulting in low cost and eliminating the need to replace the bottom shell 100. A first protrusion 220 is located at the top of the bottom shell 100, and has a first through hole 221 inside. A second through hole 222 is further provided at the bottom of the first through hole 221, extending through to the threaded hole 212 on the replacement block 211, providing a path for the fastening bolt 240 to pass through. A top recess 230 is provided on the top of the top shell 110, and a third through hole 231 is provided inside the top shell 110. The third through hole 231 is aligned with the first through hole 221 on the first protrusion 220, allowing the fastening bolt 240 to pass through the top shell 110 and enter the threaded hole 212 of the bottom shell 100. The end of the fastening bolt 240 is threaded, which can fit tightly with the threaded hole 212 on the replacement block 211. When the fastening bolt 240 is tightened, the top shell 110 can be firmly fixed to the bottom shell 100, thereby ensuring the stability of the entire circuit board.

[0063] By replacing the threaded hole 212 on the block 211 and engaging with the fastening bolt 240, the locking assembly 200 achieves a secure connection between the top shell 110 and the bottom shell 100, ensuring that the circuit board will not loosen or deform during use. Furthermore, despite the use of a threaded connection, the design of the locking assembly 200 simplifies disassembly while ensuring that disassembly does not damage the top shell 110 or the bottom shell 100, thus extending their service life.

[0064] Furthermore, the locking component 200 also includes:

[0065] The second protrusion 250 is disposed in the top groove 230, and the top of the third through hole 231 passes through the second protrusion 250;

[0066] A concealed cover 260 is disposed on and connected to the second protrusion 250. A fourth through hole 261 communicating with the third through hole 231 is provided on the concealed cover 260.

[0067] When the concealed cover 260 is engaged with the second protrusion 250, the horizontal height of the concealed cover 260 is lower than the horizontal height of the surface of the top shell 110.

[0068] The second protrusion 250 is disposed within the top groove 230, through which the top of the third through hole 231 can pass. This not only provides a more stable support point for the fastening bolt 240, but also ensures that the bolt remains vertical during tightening, thereby reducing wear caused by angular deviation. The concealed cover 260 is disposed on and connected to the second protrusion 250. It has a fourth through hole 261 that communicates with the third through hole 231, ensuring that the fastening bolt 240 can pass smoothly through the concealed cover 260, the second protrusion 250, the first protrusion 220, and the threaded hole 212 on the replacement block 211, thereby fixing the top shell 110 and the bottom shell 100. Meanwhile, when the concealed cover 260 is engaged with the second protrusion 250, its horizontal height is lower than that of the surface of the top shell 110. This not only provides protection and prevents the fastening bolts 240 from wearing down the first protrusion 220 after tightening, but also avoids some components from protruding after installation, thus playing a concealing role and making the entire circuit board look neater and more beautiful.

[0069] Example 3:

[0070] This application provides a circuit board with easily replaceable panels. In addition to the above-mentioned technical features, the circuit board with easily replaceable panels in this application also includes the following technical features.

[0071] like Figure 4 As shown, the inner diameters of the first through hole 221 and the third through hole 231 are the same and larger than the diameter of the fastening bolt 240, and the inner diameters of the third through hole 231 and the fourth through hole 261 are the same as the diameter of the fastening bolt 240.

[0072] In this embodiment, the inner diameters of the first through hole 221 and the third through hole 231 are the same and both larger than the diameter of the fastening bolt 240. This allows the fastening bolt 240 to pass through the through holes without thread contact, thus avoiding wear caused by thread friction. Simultaneously, it ensures that the fastening bolt 240 remains perpendicular during tightening, reducing additional wear caused by angular deviation. Unlike the first and third through holes 221 and 231, the third and fourth through holes 231 are the initial and final through holes through which the fastening bolt 240 passes, respectively. Their inner diameters are the same as the diameter of the fastening bolt 240, serving as a limiting function to prevent displacement and ensuring that the fastening bolt 240 can tightly pass through each through hole and smoothly enter the threaded hole 212 on the replacement block 211.

[0073] Example 4:

[0074] This application provides a circuit board with easily replaceable panels. In addition to the above-mentioned technical features, the circuit board with easily replaceable panels in this application also includes the following technical features.

[0075] like Figure 4 As shown, the auxiliary component 300 includes:

[0076] The positioning block 310 is located at the bottom of the top shell 110, and a mating groove 311 is provided at the bottom to enclose the first protrusion 220;

[0077] A pressure ring 320 is disposed on the outer wall of the fastening bolt 240;

[0078] Spring 330 is disposed in the first through hole 221 and sleeved on the outside of fastening bolt 240;

[0079] After the top cover and bottom cover are installed, the inner wall of the mating groove 311 contacts the outer wall of the first protrusion 220.

[0080] In this embodiment, the positioning block 310 is disposed at the bottom of the top shell 110, and a mating groove 311 is provided at its bottom. The shape and size of the mating groove 311 are perfectly matched with the first protrusion 220. When the top shell 110 and the bottom shell 100 are installed together, the inner wall of the mating groove 311 will be in close contact with the outer wall of the first protrusion 220, thereby playing a guiding and positioning role. The pressure ring 320 is disposed on the outer wall of the fastening bolt 240. It is a ring structure, which increases the contact area between the bolt and the surrounding structure and also improves the stability of the bolt during the tightening process. The spring 330 is disposed in the first through hole 221 and sleeved on the outer wall of the fastening bolt 240. When the fastening bolt 240 is tightened, the spring 330 is compressed and stores a certain amount of elastic force. This elastic force not only provides additional preload force, enhancing the connection stability between the top shell 110 and the bottom shell 100, but also plays an assist role in the disassembly process, making the bolt easier to loosen and reducing the time required for disassembly.

[0081] Furthermore, there is a gap between the pressure ring 320 and the inner wall of the first through hole 221.

[0082] In some embodiments of this application, the gap between the pressure ring 320 and the inner wall of the first through hole 221 can significantly reduce the friction between the two. During the tightening or loosening of the fastening bolt 240, the gap allows the pressure ring 320 to have a certain amount of room to move within the first through hole 221, thereby avoiding friction caused by close contact.
