[0022] 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. Example 1

[0023] Please see Figure 1-4 In this embodiment: a multi-layered overlapping circuit board includes a first circuit board 1 and a second circuit board 2. Electronic components 3 are fixedly connected to the top of the first circuit board 1 and the second circuit board 2 respectively. Grooves are respectively opened on the front and rear sides of the first circuit board 1 and the second circuit board 2. The outer sides of two conductive wire strips 6 are in contact with the inner walls of the grooves. The second circuit board 2 is arranged below the first circuit board 1. Electronic components 3 are fixedly connected to the top of the first circuit board 1. Mounting holes 4 are respectively opened around the top of the first circuit board 1. A power interface 5 is fixedly connected to the top right side of the first circuit board 1. The bottom end of the power interface 5 is fixedly connected to the top right side of the first circuit board 1. Conductive wire strips 6 are respectively arranged on the front and rear sides of the first circuit board 1. The bottom ends of the two adjacent sides of the two conductive wire strips 6 are respectively fixedly connected to the front and rear ends of the second circuit board 2. Power connection holes 7 are respectively opened on the top of the front and rear sides of the first circuit board 1. Isolation components are arranged around the top of the first circuit board 1.

[0024] In this embodiment, when an external power source is connected to the first circuit board 1 through the power interface 5, the power interface 5 transmits electrical energy to the circuit system of the first circuit board 1. After receiving electrical energy, the electronic components 3 on the first circuit board 1 begin to work, performing corresponding circuit functions, signal processing, and data calculation. At the same time, the first circuit board 1 needs to interact with the second circuit board 2 for data exchange and power transmission. At this time, the conductive strip 6 plays a role. The first circuit board 1 is connected to the conductive strip 6 through the power connection holes 7 on the front and rear sides, and the signals and power to be transmitted to the second circuit board 2 are conducted to the second circuit board 2 through the conductive strip 6. After receiving the signals and power from the first circuit board 1, the electronic components 3 on the second circuit board 2 also begin to work, performing corresponding processing and calculation. The second circuit board 2 can also feed back the processed signals to the first circuit board 1 through the conductive strip 6, realizing bidirectional communication and collaborative work between the two circuit boards. Example 2

[0025] like Figure 1 - Figure 4 As shown, the isolation assembly includes multiple connecting posts 8. The bottom outer edges of the multiple connecting posts 8 are in contact with the inner walls of the four corners of the second circuit board 2, and the top edges of the connecting posts 8 are in contact with the inner walls of the four corners of the first circuit board 1. Limiting plates 9 are fixedly connected to the bottom edges of the multiple connecting posts 8 respectively. Isolation rings 2 11 are sleeved on the bottom outer edges of the connecting posts 8. The bottom edges of the multiple isolation rings 2 11 are in contact with the top edges of the second circuit board 2. A shielding plate 12 is provided at the top edge of the isolation rings 2 11. An isolation ring 10 is provided at the top edge of the shielding plate 12. The top edges of the multiple isolation rings 10 are in contact with the bottom edge of the first circuit board 1.

[0026] In this embodiment, the connecting post 8 firmly supports the first circuit board 1, maintaining a stable overlapping structure with the second circuit board 2, providing a stable physical environment for the normal operation of the electronic component 3. The limiting plate 9 ensures the fixed position of the connecting post 8, preventing the circuit board structure from loosening due to external forces. The first isolation ring 10 and the second isolation ring 11, with their insulation properties, cut off the electrical path between the circuit board and the connecting post 8, preventing current leakage and short circuits. The shielding plate 12 plays a crucial role in electromagnetic protection. When there is an external electromagnetic interference source, the shielding plate 12 can reflect or absorb the interference signal, preventing it from entering the circuit board and affecting the operation of the electronic component 3. At the same time, the electromagnetic signals generated by the circuit board during operation are also blocked by the shielding plate 12, preventing them from radiating outward and avoiding interference with other surrounding electronic devices. Through the coordinated work of the isolation components and the main structure of the circuit board, the multi-layer overlapping circuit board can operate stably in a complex electromagnetic environment, ensuring the accuracy of signal transmission and the reliability of power supply.

[0027] The working principle and usage process of this utility model are as follows: When an external power source is connected to the first circuit board 1 through the power interface 5, the electronic components 3 on the first circuit board 1 begin to work and execute corresponding circuit functions. The first circuit board 1 and the second circuit board 2 transmit signals and power through the conductive wire strip 6. During this process, the connecting post 8 stably supports the first circuit board 1, maintaining a stable overlapping structure with the second circuit board 2, providing a stable physical environment for the normal operation of the electronic components 3. The limiting plate 9 ensures that the position of the connecting post 8 is fixed, preventing the circuit board structure from loosening due to external forces. The first isolation ring 10 and the second isolation ring 11, with their insulation properties, cut off the electrical path between the circuit board and the connecting post 8, preventing current leakage and short circuits.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
