[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.

[0024] This utility model provides the following technical solution:

[0025] As attached Figure 1-5 As shown in the accompanying drawings, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] This utility model provides the following technical solution:

[0028] As attached Figure 1-5As shown, this utility model discloses a novel electric track, including a track body 1 and a storage box 2 disposed on one side of the track body 1. The storage box 2 houses a circuit board 3, a transformer 4, and a plug-in assembly 5. Both the transformer 4 and the plug-in assembly 5 are mounted on and electrically connected to the circuit board 3. The circuit board 3 has mounting holes 6, and the transformer 4 is disposed within these holes. The partial thickness of the transformer 4 coincides with the thickness of the circuit board. In this embodiment, the storage box 2 is a PCBA storage box, which centrally integrates power conversion and distribution functions. Basic power conduction is achieved through the built-in circuit board 3, voltage regulation is performed by the transformer 4 to meet the needs of different devices, and the plug-in assembly 5 provides a standardized power supply interface. This design enables the storage box 2 to simultaneously perform three functions: power adaptation, interface integration, and safety protection. It ensures stable output voltage through the transformer 4 and enables plug-and-play functionality through the USB / Type-C interface of the connector 5. The structure of the limiting plate 15 and the fixing plate 21 effectively prevents poor electrical contact and interface misalignment. In this embodiment, the transformer 4 and the circuit board 3 have locally overlapping thicknesses, allowing the overall storage box 2 to be thinner. Unlike existing designs where the transformer 4 is mounted on the circuit board 3, this design's overlapping thickness not only thins the components but also adds a secondary thinning design, further optimizing towards ultra-thinness. This thin design not only saves installation space but also improves the product's aesthetics and portability.

[0029] Furthermore, the circuit board 3 divides the interior of the storage box 2 into an upper cavity 7 and a lower cavity 8. The mounting holes 6 connect the upper cavity 7 and the lower cavity 8 respectively, and the upper and lower parts of the transformer 4 extend into the upper cavity 7 and the lower cavity 8 respectively. In this embodiment, the upper cavity 7 and the lower cavity 8 optimize the space constraints for transformer installation through a layered layout. The upper cavity 7 mainly accommodates the upper structure of the transformer 4 and part of the wiring connection area of ​​the plug-in component 5, while the lower cavity 8 is used to arrange the lower structure of the transformer 4. This layered design not only allows the heat of the transformer 4 to be effectively dissipated through the airflow between the upper and lower cavities, reducing the impact of local temperature rise on circuit stability, but also reduces the potential impact of electromagnetic interference on the signal transmission of the plug-in component 5 through physical isolation. At the same time, the through structure of the mounting holes 6 ensures that the electrical connection path between the transformer 4 and the circuit board 3 is minimized, reducing contact resistance and energy loss.

[0030] Furthermore, the track body 1 includes a housing 9 and a conductive strip 10 disposed within the housing 9. One end of the conductive strip 10 extends towards the storage box 2, and a conductive slot 11 is provided on the conductive strip 10. Slots 12 are provided on both sides of the conductive slot 11. A power-feeding connector 13 is provided on the end of the conductive strip 10 near the storage box 2. One end of the power-feeding connector 13 extends into the slot 12 and tightly engages with the conductive strip 10. The other end of the power-feeding connector 13 is connected to the circuit board 3, thus electrically connecting the conductive strip 10 and the circuit board 3. In this embodiment, the power-feeding connector 13 is a spring, and the slot 12 provides precise installation and positioning space for the power-feeding connector 13, ensuring accurate installation of the power-feeding connector 13 on the conductive strip 10. The tight fit between the slot 12 and one end of the power-feeding connector 13 effectively fixes the position of the power-feeding connector 13, preventing it from shifting or loosening during long-term use, thus ensuring the stability of the electrical connection between the conductive strip 10 and the circuit board 3. Simultaneously, the spring design of the power-feeding connector 13 helps to disperse the stress generated during compression and extension, extending the service life of the power-feeding connector 13 and the entire conductive structure, enabling the power rail to continuously and reliably perform its power conduction function during operation. In this embodiment, the power-feeding connector 13, in conjunction with the circuit board 3, enables press-fit power delivery. The limiting plate 15 on the storage box 2 further limits the power-feeding connector 13, ensuring the accuracy of the press-fit process and preventing problems such as excessive insertion between the storage box 2 and the rail body 1. When the storage box 2 is connected to external equipment, the power-feeding connector 13 always maintains tight contact with the circuit board 3, thereby forming a stable current path. This press-fit power delivery method significantly improves the durability and maintenance convenience of the power rail. In this embodiment, an insulating sleeve 14 is also provided on the outside of the conductive strip 10. The insulating sleeve 14 tightly wraps around the outside of the corresponding conductive strip 10, providing reliable insulation protection for the conductive strip 10. In other cases, the power-taking connector 13 can also be a pin or other connector capable of power connection. In this embodiment, other power rail components are existing rail structures, which will not be described in detail here.

[0031] Furthermore, a limiting plate 15 protrudes from the storage box 2 corresponding to the position of the power-taking connector 13, and the limiting plate 15 passes through the circuit board 3 and is positioned at one end of the power-taking connector 13. In this embodiment, the limiting plate 15 precisely limits the connection range of the power-taking connector 13. Through the synergistic effect of the limiting plate 15 and the power-taking connector 13, it can be ensured that the conductive strip 10 and the circuit board 3 maintain a stable contact pressure during the crimping power-taking process, preventing poor contact due to insufficient pressure or damage to the component surface due to excessive pressure. This deep integration of mechanical limiting structure and electrical connection function effectively improves the reliability of the power rail in complex operating environments. At the same time, the limiting plate 15 is made of insulating material, which, in addition to its structural support function, also has an electrical isolation function, preventing operators from accidentally touching live parts. Combined with the overall protective design of the housing 9, it forms a multi-level safety protection system.

[0032] Furthermore, the transformer 4 is a planar transformer 16 with a cross-sectional height of 8mm, and the circuit board 3 has a cross-sectional height of 3mm. In this embodiment, the planar transformer 16 serves to minimize the overall thickness of the track while achieving efficient voltage conversion within a limited space. Its 8mm cross-sectional height, after extending into the circuit board 3, complements the 3mm cross-sectional height of the circuit board, forming a structure with a height of 8mm (5mm above the circuit board 3), together constructing a thin storage box 2 structure. This design not only reduces the overall height of the power track, but also, in this embodiment, maximizes the thinning of the power track through the placement of the planar transformer 16. By integrating the planar transformer 16 onto the circuit board 3, the integrated power conversion and conduction functions are achieved, further improving the system integration and reliability of the power track. In the prior art, the thickness of the storage box 2 is generally 13mm-16mm.

[0033] Furthermore, the plug-in assembly 5 includes a USB connector 17 and a Type-C connector 18, which supply power to the outside via the circuit board 3. In this embodiment, the plug-in assembly 5 provides diverse standardized power supply interfaces for the power rail, meeting the charging needs of different types of electronic devices. The USB connector 17, as a widely used interface type, is compatible with most traditional electronic devices, while the Type-C connector 18, with its bidirectional power supply and high-speed transmission characteristics, is suitable for high-power demand scenarios such as new smart devices and thin and light laptops. The combination of these two interfaces covers the charging needs of existing devices, making the power rail more versatile. In this embodiment, the storage box 2 is equipped with USB and Type-C interfaces corresponding to the positions of the USB connector 17 and Type-C connector 18.

[0034] Furthermore, a junction box 19 is provided on the side of the track body 1 away from the storage box 2. A terminal block 20 is installed inside the junction box 19. The end of the conductive strip 10 away from the storage box 2 extends towards the terminal block 20, and one side of the terminal block 20 extends into the conductive slot 11 and is electrically connected to the conductive strip 10. In this embodiment, the junction box 19 serves as the connection hub between the electric track and the external power source, enabling safe and reliable power access. The junction box 19 is made of insulating material, providing physical protection for the internal terminal block 20 and effectively isolating live parts to prevent accidental electric shock. The connection method of the terminal block 20 extending into the conductive slot 11 creates a closed-loop power conduction path. Simultaneously, the slots 12 on both sides of the conductive slot 11 provide precise positioning for the installation of the terminal block 20, ensuring accurate connection between the conductive strip 10 and the terminal block 20 during each wiring operation, avoiding poor contact or localized overheating due to positional deviations. The conductive slot 11 clamps the inserted terminal 20. This clamping structure enhances the stability of the conductive contact through mechanical compression, effectively reducing the risk of loosening due to vibration or thermal expansion and contraction. In this embodiment, the other structures of the junction box 19 are common in the prior art and will not be described in detail in this application. In this embodiment, the conductive slot 11 functions to cooperate with the adapter to output power.

[0035] Furthermore, a fixing plate 21 protrudes from the storage box 2, which limits the movement of the circuit board 3 within the storage box 2. In this embodiment, the fixing plate 21 limits the movement of the circuit board 3, ensuring that different interface types are neatly arranged within the storage box 2. The fixing plate 21 also restricts the position of the plug-in assembly 5, preventing it from shifting or loosening due to external forces, thereby ensuring the accuracy and stability of the plug-in operation. This design not only improves the overall aesthetics of the power rail but also avoids the risk of poor contact or short circuits caused by misaligned interfaces.

[0036] In this embodiment, the conductive strip 10 has a plurality of through holes 22 evenly distributed on one side near the conductive slot 11. The through holes 22 on the conductive strip 10 optimize the electrical performance and structural strength of the conductive strip 10. These evenly distributed through holes 22 can effectively reduce the overall weight of the conductive strip 10, reduce material usage while maintaining the conductive cross-sectional area, thereby improving the product's economy. The through hole 22 design also forms a heat dissipation channel, allowing the heat generated when current passes through the conductive strip 10 to dissipate more quickly through the through hole 22 area. In terms of mechanical performance, the material around the through holes 22 is designed with stress dispersion to enhance the bending resistance of the conductive strip 10, preventing deformation due to thermal expansion and contraction or external forces during long-term use. In addition, the through hole 22 layout also provides an elastic buffer space for the sidewall of the conductive slot 11. When the terminal 20 is inserted into the conductive slot 11, the sidewall can ensure close contact with the terminal 20 through slight deformation, while avoiding material fatigue caused by rigid contact. This structural optimization allows the conductive strip 10 to meet the requirements of high current conduction and maintain long-term stability in complex operating environments. In terms of manufacturing process, the through hole 22 is formed in one step using precision stamping technology to ensure the consistency of hole diameter. This standardized production method helps to improve product yield and reduce manufacturing costs.
