Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to circuit board wiring structure. Background Technology

[0002] A circuit board is a component in electronic products. It is formed by processing conductive patterns on an insulating substrate to achieve electrical connections and signal transmission between electronic components. A circuit board consists of an insulating substrate, conductive lines, connecting pads, and a cover layer. According to its structure, it is divided into single-sided boards, double-sided boards, and multilayer boards. Circuit boards carry the functions of current conduction and signal transmission, and their performance directly affects the stability and reliability of the equipment.

[0003] The circuit board wiring structure uses etching technology to form the required conductive lines on a copper foil substrate. Electrical connections between different layers are achieved through vias. Multilayer circuit boards typically fill the layers with insulating dielectric material and use electroplating technology to metallize the holes, ensuring the integrity of signal transmission. Surface mount technology is used for circuit board assembly, where electronic components are directly soldered onto the board surface and connected to the lines through pads. The wiring structure meets the electrical performance requirements of electronic equipment by planning the routing layout and optimizing the signal flow between layers.

[0004] Existing circuit board wiring structures have shortcomings in heat dissipation performance. When the circuit board is running, the heat generated by electronic components is conducted to the outside through copper lines and substrate. In the existing structure, the insulating dielectric material effectively isolates different conductive layers, but its low thermal conductivity hinders the rapid dissipation of heat. The interlayer stacking design of multilayer boards causes heat to accumulate between layers. The limited thickness of the metallized plating layer through the via restricts the vertical heat conduction efficiency. When electronic equipment is operating under high load, a large amount of heat generated by the components cannot be conducted to the heat dissipation device through the circuit board in time, resulting in local overheating. This leads to unstable signal transmission and equipment malfunctions, which are factors that restrict the improvement of circuit board performance. Utility Model Content

[0032] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a circuit board wiring structure, including an insulating substrate 1. The insulating substrate 1 provides insulation for the circuit board, ensuring the stability of its electrical performance. An insulating plate 3 is fixedly connected to the top of the insulating substrate 1, further enhancing the insulation effect and preventing short circuits between the conductive plate 4 and the insulating substrate 1. A conductive plate 4 is fixedly connected to the top of the insulating plate 3, serving as the conductive carrier of the circuit board and undertaking current transmission. Multiple positioning holes 5 penetrate the interior of the insulating substrate 1, the insulating plate 3, and the conductive plate 4. The positioning holes 5 provide positioning channels for heat-conducting pillars 6, ensuring the accuracy and stability of their installation. Heat-conducting pillars 6 are slidably connected inside the multiple positioning holes 5, transferring the heat generated by the conductive plate 4 to the heat-conducting plate 7, improving the heat dissipation efficiency of the circuit board. Each heat-conducting column 6 is fixedly connected to a heat-conducting plate 7. The heat-conducting plate 7 can absorb the heat transferred by the heat-conducting column 6 over a large area and dissipate it to the surrounding environment, thus accelerating the heat dissipation speed. A serpentine heat dissipation tube 8 is fixedly connected inside the insulating substrate 1. The serpentine heat dissipation tube 8 enhances the heat dissipation effect on the circuit board and improves the heat dissipation efficiency through the internal flowing heat dissipation liquid. The left end of the serpentine heat dissipation tube 8 is connected to a heat dissipation liquid tank 9. The heat dissipation liquid tank 9 is used to store heat dissipation liquid and ensure a continuous supply of heat dissipation liquid in the serpentine heat dissipation tube 8. The top of the heat dissipation liquid tank 9 is fixedly connected to a filling port 10. The filling port 10 allows users to easily add heat dissipation liquid to the heat dissipation liquid tank 9 to ensure normal heat dissipation operation. A protective mechanism 2 is provided at the bottom of the insulating substrate 1. The protective mechanism 2 is used to protect the internal electronic components and prevent them from being damaged by external impacts or dust intrusion.

[0033] Specifically, during the operation of the circuit board wiring structure, current is transmitted through the conductive plate 4 under the insulation protection of the insulating substrate 1 and the insulating plate 3. The insulating plate 3 enhances the insulation effect, preventing short circuits between the conductive plate 4 and the insulating substrate 1, and ensuring stable electrical performance. The conductive plate 4 generates heat during current transmission. The heat is transferred upward to the heat-conducting plate 7 through the heat-conducting pillar 6 in the positioning hole 5. The positioning hole 5 provides positioning for the heat-conducting pillar 6, ensuring stable installation. After receiving the heat, the heat-conducting plate 7 dissipates it to the surrounding environment through contact with the air, accelerating the heat dissipation rate. The serpentine heat dissipation pipe 8 inside the insulating substrate 1 also plays a role in cooling. The function of the heat dissipation liquid flowing inside the tube is to absorb the heat inside the circuit board. After sufficient heat exchange through the serpentine path, the heat is carried to the heat dissipation liquid tank 9. The heat dissipation liquid tank 9 stores the heat dissipation liquid, ensuring continuous circulation of the liquid inside the serpentine heat dissipation tube 8. Users can replenish the heat dissipation liquid through the filling port 10 at the top of the heat dissipation liquid tank 9 to maintain the normal operation of the heat dissipation system. The protective mechanism 2 at the bottom of the insulating substrate 1 plays a protective role, resisting external impacts and preventing dust and foreign objects from entering, creating a safe and stable working environment for the electronic components inside the circuit board, realizing stable current transmission and efficient heat dissipation of the circuit board, and ensuring the normal operation of the circuit board.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The protective mechanism 2 includes a protective shell 201. The top inner side of the protective shell 201 is fixedly connected to the bottom of the insulating substrate 1, which encloses and protects the space below the insulating substrate 1. A support plate 202 is fixedly connected to the top inner side of the protective shell 201. The support plate 202 serves as a support component. A fixing plate 203 is fixedly connected to the top of the support plate 202. The fixing plate 203 is used to fix the component. A rubber plate 204 is fixedly connected to the inner side of the fixing plate 203. The rubber plate 204 serves as a buffer and protects the internal components. A temperature sensor 205 is fixedly connected to the bottom left side of the protective shell 201. The temperature sensor 205 is used to sense the temperature inside the protective shell 201. A transmission line 206 is connected to the left side of the temperature sensor 205. The transmission line 206 is used to transmit the temperature data sensed by the temperature sensor 205. The transmission line 206 passes through the left side of the protective shell 201 and is fixedly connected to a temperature display 207. The temperature display 207 displays the transmitted temperature data.

[0035] Specifically, the top inner side of the protective shell 201 is connected to the bottom of the insulating substrate 1, forming a closed space to isolate external interference and provide a safe and stable operating environment for the internal components. Inside the protective shell 201, the support plate 202 provides support for the upper fixing plate 203, ensuring the stability of the fixing plate 203. The fixing plate 203 is used to fix the components. The inner rubber plate 204 buffers external impacts and vibrations, preventing the fixed components from being damaged by collisions and improving the safety of the internal components. The temperature sensor 205 at the bottom left side of the protective shell 201 monitors the internal temperature of the protective shell 201 in real time. Once the temperature changes, the temperature sensor 205 will activate the sensor. The sensed temperature signal is transmitted through transmission line 206, which runs through the left side of the protective shell 201. The transmission line 206 stably and accurately transmits the temperature signal to the temperature display 207. After receiving the temperature data from the transmission line 206, the temperature display 207 converts it into digital form. By observing the value on the temperature display 207, the staff can monitor the temperature inside the protective shell 201 in real time. If the temperature is abnormal, the staff can take timely measures to adjust the environment inside the protective shell 201 to ensure that the internal components operate under suitable temperature conditions and ensure the stable and reliable operation of the entire device.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The protective shell 201 has fixed blocks 11 on its front and rear top sides, which facilitates component connection and provides grip points for easy operation. Handles 12 are fixedly connected to the opposite sides of the two front and two rear fixed blocks 11, allowing users to easily move the protective shell 201 and improving usability. Fixing pins 13 are slidably connected to the support plate 202 around its perimeter. These pins allow for adjustment of the positional relationship between the support plate 202 and the protective shell 201, meeting various installation requirements. Multiple fixing pins 13 are fixedly connected to the bottom of the inner side of the protective shell 201, so that the support plate 202 can be stably installed inside the protective shell 201 to ensure structural stability. A positioning pad 15 is fixedly connected to the upper middle part of the front side of the protective shell 201. The positioning pad 15 plays a positioning and buffering role to prevent the components from having a hard collision with the protective shell 201 and to protect the internal circuit board components. A data plug 16 is fixedly connected to the inner side of the positioning pad 15. The data plug 16 realizes data connection and transmission with external devices, which facilitates data interaction between devices.

[0037] Specifically, when the user needs to move the protective shell 201, they can directly grasp the handle 12 and move it easily through the stable connection of the fixing block 11. During the installation process, the user can adjust the position of the fixing pin 13 on the support plate 202 according to actual needs, changing the relative position relationship between the support plate 202 and the protective shell 201. After the adjustment is completed, the bottom of the fixing pin 13 is fixed to the bottom of the inner side of the protective shell 201 to ensure the stable installation of the support plate 202. During the use of the equipment, the positioning pad 15 protects the stable installation of the data plug 16. The data plug 16 connects with external devices to realize data transmission and interaction, meeting the needs of data interaction between devices.

[0038] Reference Figure 1 , Figure 3 and Figure 5 Two equidistant reaction lights 17 are fixedly connected to the top rear side of the conductive plate 4, which can display the working status of electronic components. Multiple anti-slip pads 14 are fixedly connected to the bottom of the protective shell 201 to increase the stability when placed. A buzzer 18 is fixedly connected to the top of the conductive plate 4 to emit an alarm sound. A moisture-proof window 19 is fixedly connected to the top of the protective shell 201. A transparent plate 20 is opened on the inside of the moisture-proof window 19 to block the entry of dust and air. The internal situation can be observed through the transparent plate 20, which improves the operator's understanding of the circuit board.

[0039] Specifically, when the equipment is running, the conductive plate 4 senses and transmits the working status information of the electronic components in real time. The two reaction lights 17 receive the signals transmitted by the conductive plate 4 and display the working status of the electronic components in different light states. Once the conductive plate 4 detects an abnormal signal, the buzzer 18 will immediately start to sound an alarm, promptly reminding the operator to pay attention to the fault and take countermeasures. Multiple anti-slip pads 14 can effectively increase the stability of the equipment when it is placed, avoid the impact of the equipment sliding or shaking on the normal operation of the internal electronic components, and ensure the stability of the equipment during operation. The moisture-proof window 19 effectively blocks external dust and air from entering the equipment, preventing the electronic components from being damaged by moisture. The transparent plate 20, while blocking dust and air from entering, allows the operator to observe the working status of the circuit boards and parts inside the equipment, making it easier to detect problems and carry out maintenance in a timely manner.

[0040] Working principle: When the circuit board starts working, the current is transmitted through the conductive plate 4 under the insulation protection of the insulating substrate 1 and the insulating plate 3, avoiding short circuits between the conductive plate 4 and the insulating substrate 1, and ensuring stable electrical performance. The conductive plate 4 generates heat during the current transmission process. The heat is transferred upward to the heat-conducting plate 7 through the heat-conducting column 6 in the positioning hole 5. After receiving the heat, the heat-conducting plate 7 dissipates to the surrounding environment by contacting the air, which accelerates the heat dissipation speed. The serpentine heat pipe 8 plays a role in cooling. The heat dissipation liquid flowing in the pipe absorbs the heat inside the circuit board. After sufficient heat exchange through the serpentine path, the heat is carried to the heat dissipation liquid tank 9. The heat dissipation liquid tank 9 stores the heat dissipation liquid, ensuring that the liquid in the serpentine heat pipe 8 continues to circulate. The user replenishes the heat dissipation liquid through the filling port 10 to maintain the normal operation of the heat dissipation system, realize stable current transmission and efficient heat dissipation of the circuit board, and ensure the normal operation of the circuit board.

[0041] The protective shell 201 is connected to the insulating substrate 1, forming a closed space that isolates external interference and provides a safe and stable operating environment for the internal components. The support plate 202 provides support for the upper fixing plate 203, ensuring the stability of the fixing plate 203. The rubber plate 204 buffers external impacts and vibrations, preventing damage to the fixing components due to collisions and improving the safety of the internal components. The temperature sensor 205 monitors the internal temperature of the protective shell 201 in real time. Once the temperature changes, the temperature sensor 205 transmits the sensed temperature signal through the transmission line 206, stably and accurately transmitting the temperature signal to the temperature display 207. After receiving the temperature data from the transmission line 206, the staff can observe the value on the temperature display 207 to monitor the internal temperature of the protective shell 201 in real time. If the temperature is abnormal, the staff can take timely measures to adjust the internal environment of the protective shell 201 to ensure that the internal components operate under suitable temperature conditions and ensure the stable and reliable operation of the entire equipment.
