[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 circuit board with a built-in wiring partition structure, including a circuit board body 1, an upper plate 2, a built-in wiring board 4, and a lower plate 3 on the circuit board body 1. The upper plate 2 and the lower plate 3 are symmetrically arranged, and the dimensions of the upper plate 2 and the lower plate 3 are both larger than the dimensions of the built-in wiring board 4. Sloping grooves are respectively formed on the outer ring of the opposite side of the upper plate 2 and the lower plate 3. This structure allows the built-in wiring board 4 to be completely pressed into the upper plate 2 and the lower plate 3. The sloping grooves provide a disassembly point between the upper plate 2 and the lower plate 3, allowing the circuit board body 1 to be repaired and reducing the probability of the circuit board body 1 being scrapped due to failure. The built-in terminal block 4 has wiring slots 402 on its upper and lower sides, and metal wiring modules 403 are evenly spaced and pressed and fixed within the wiring slots 402 areas of the built-in terminal block 4. The upper plane of the built-in terminal block 4 is higher than the upper plane of the metal wiring modules 403. The circuit connection between the metal wiring modules 403 is designed according to the design requirements. After the upper plate 2 and lower plate 3 are pressed together, the built-in terminal block 4 can avoid excessive pressure on the metal wiring modules 403, and facilitate the connection of the circuits between the metal wiring modules 403. In addition, the built-in terminal block 4 also has snap-fit ​​protrusions 401 integrally provided at corresponding positions on the upper and lower sides. On opposite sides, a first latching slot 202 and a second latching slot 302 are respectively provided, and the first latching slot 202 and the second latching slot 302 are respectively fastened to the built-in wiring board 4. This structure allows the upper plate 2 and the lower plate 3 to perform latching and positioning of the built-in wiring board 4 through the first latching slot 202 and the second latching slot 302. The independent design of the built-in wiring board 4 allows for more complex and dense circuit wiring. The upper plate 2 and the lower plate 3 have corresponding positions of a first mounting hole 201 and a second mounting hole 301, respectively. The first mounting hole 201 and the second mounting hole 301 are both T-shaped hole structures, and the first mounting hole 201 and the second mounting hole 301 are T-shaped hole structures. The smaller diameter portion of 301 is securely fastened to the snap-fit ​​protrusion 401. This structure, with its T-hole design for the first mounting hole 201 and the second mounting hole 301, allows the circuit board body 1 to be easily installed and fixed with screws. The first mounting hole 201 and the second mounting hole 301 are respectively engaged with the snap-fit ​​protrusion 401. A pre-embedded metal threaded cylinder 404 is provided inside the snap-fit ​​protrusion 401, and the depth of the pre-embedded metal threaded cylinder 404 is equal to the farthest distance between the snap-fit ​​protrusion 401 and the metal threaded cylinder 404. This structure allows the pre-embedded metal threaded cylinder 404 to be tightly connected to the snap-fit ​​protrusion 401 through pre-embedding, providing reliable positioning for the installation of the circuit board body 1.

[0018] Working principle: When using this circuit board with built-in wiring partition structure, firstly, recessed wiring grooves 402 are respectively set on the upper and lower surfaces of the built-in wiring board 4. The metal wiring module 403 is pressed and fastened onto the built-in wiring board 4. The wiring grooves 402 provide installation gaps between the metal wiring module 403 and the upper plate 2 and lower plate 3 to prevent the metal wiring module 403 from being crushed. Then, according to the circuit design requirements, the metal wiring modules 403 at the corresponding positions are connected, which reduces electromagnetic interference at the wiring points, greatly simplifies the design of complex circuits, and improves overall performance. 4. The upper plate 2 and the lower plate 3 are engaged with the first snap-fit ​​groove 202 and the second snap-fit ​​groove 302. When the upper plate 2 and the lower plate 3 are pressed together, the snap-fit ​​protrusion 401 is tightly snapped into the first mounting hole 201 and the second mounting hole 301, so that the mounting holes of the upper plate 2, the built-in terminal block 4 and the lower plate 3 are integrated. The circuit board body 1 is installed and positioned by the pre-embedded metal threaded cylinder 404 in the built-in terminal block 4. The groove set on the outer ring between the upper plate 2 and the lower plate 3 can facilitate the disassembly and maintenance of the circuit board body 1, 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.
