Description

Technical Field

[0001] This utility model relates to the field of capacitor-powered power supply technology, specifically a built-in rear-mounted capacitor-powered power supply. Background Technology

[0002] Traditional built-in rear-mounted capacitor-powered power supplies typically use an integrated encapsulation structure. When the casing ages due to high temperatures or suffers mechanical damage, the entire unit needs to be replaced, resulting in high maintenance costs and cumbersome operation.

[0003] In existing technologies, some power supplies employ a split-shell design, but this lacks sufficient sealing, making them susceptible to environmental influences and resulting in a shortened lifespan for capacitor components. Furthermore, current mounting methods often involve welding or gluing, making disassembly difficult and hindering partial replacement. Therefore, there is an urgent need for a capacitor-harvested power supply structure that ensures both sealing and rapid disassembly / reassembly for easy partial replacement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a built-in rear-mounted capacitor-powered power supply, which solves the problem of disassembling and assembling the capacitor-powered power supply casing. By splicing the casing, the casing can be easily replaced, which not only improves replacement efficiency but also saves costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a built-in rear-mounted capacitor-powered power supply, comprising a power supply body, a protective mechanism on the outside of the power supply body, the protective mechanism comprising a connecting seat, a top seat, and a splicing shell, the splicing shell being sealed and fixed to the connecting seat and the top seat by a fixing mechanism; the upper and lower ends of the splicing shell are provided with first grooves, the outer sides of the top seat and the connecting seat are provided with second grooves, the fixing mechanism comprising a sealing fixing strip and a sealing hoop, the sealing hoop being provided with a matching groove, the matching groove being misaligned with the first groove and the second groove to form a seal.

[0006] Furthermore, the sealing ring has an installation hole at its end, and the bolt passes through the installation hole to tighten the sealing ring, so that the sealing strip and the sealing ring seal and fix the spliced ​​shell.

[0007] Furthermore, the inner walls of the top seat and the connecting seat are provided with convex rings, and the inner side walls of the upper and lower ends of the splicing shell are provided with splicing grooves. The convex rings and splicing grooves are matched and connected to improve the ease of installation.

[0008] Furthermore, the splicing shell can be disassembled and replaced independently without disassembling the internal capacitor components; partial replacement can be achieved only through a tightening and loosening mechanism.

[0009] Furthermore, the misaligned fit between the matching groove and the first and second grooves forms a multi-layer sealing structure, improving dustproof and moisture-proof performance.

[0010] Furthermore, the sealing and fixing strip is matched and correspondingly set to the outer side of the spliced ​​shell.

[0011] This invention provides a built-in rear-mounted capacitor-powered power supply. Compared with the prior art, it has the following advantages:

[0012] This built-in rear-mounted capacitor-powered power supply features a modular design with a modular housing and fixing mechanism, allowing for easy assembly and disassembly. Only worn parts need to be replaced, reducing maintenance costs. The staggered groove design of the sealing strip and sealing clamp creates multiple seals, improving dust and moisture resistance. The matching and docking of the convex ring and splicing groove enhances installation convenience and reduces assembly errors. The bolt fastening method facilitates quick assembly and disassembly without destructive disassembly, extending the overall service life. The independent splicing housing design avoids frequent disassembly of internal capacitor components, reducing the risk of damage. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: a built-in rear-mounted capacitor power supply; specifically, it consists of a power supply body 1. The built-in rear-mounted capacitor power supply is a high-efficiency power supply module that combines a high-voltage capacitor with an energy-harvesting transformer. The power supply body 1 utilizes the high-voltage capacitor to directly obtain and store energy from the power line. A protection mechanism is provided on the outer end of the high-voltage capacitor. The protection mechanism includes a connecting seat 2, a splicing shell 4 is provided on the upper end of the connecting seat 2, and a top seat 3 is provided on the upper end of the splicing shell 4. The connecting seat 2, the top seat 3, and the splicing shell 4 can protect the internal capacitor element. A fixing mechanism is provided on the outer end of the splicing shell 4. The fixing mechanism seals and fixes the connecting seat 2, the top seat 3, and the splicing shell 4, providing a stable connection. Thus, after aging at high internal temperatures, it is not necessary to disassemble the capacitor element. The splicing shell 4 on the outside of the capacitor element can be replaced directly. When disassembling, the fixing mechanism is removed to replace the new splicing shell 4, and then the fixing mechanism is fixed. This not only makes disassembly convenient but also allows for partial replacement of the more severely aged end, saving costs.

[0021] The protective mechanism includes a sealing strip 7, with sealing clamps 8 fixed at the upper and lower ends of the sealing strip 7. The ends of the two sealing clamps 8 are provided with mounting holes 10, and bolts 11 are inserted into the mounting holes 10. The sealing clamps 8 can be tightened by the bolts 11. The sealing clamps 8 and the sealing strip 7 seal and fix the connection between the sides and the upper and lower ends of the spliced ​​shell 4, which facilitates the connection and sealing between the connecting seat 2, the top seat 3 and the spliced ​​shell 4.

[0022] A first groove 5 is provided on the outer side of the upper and lower ends of the splicing shell 4, a second groove 6 is provided on the outer side of the top seat 3 and the connecting seat 2, and a matching groove 9 is provided inside the sealing band 8. The matching groove 9 is located on the protruding part between the first groove 5 and the second groove 6 for matching installation. A seal is formed by the misalignment between the first groove 5, the second groove 6 and the matching groove 9, achieving a better sealing effect.

[0023] A raised ring 13 is fixed on the inner wall of the top seat 3 and the connecting seat 2. A splicing groove 12 is provided on the inner side wall of the upper and lower ends of the splicing shell 4. The raised ring 13 and the splicing groove 12 are matched and connected. The splicing shell 4 can be easily installed through the raised ring 13 and the splicing groove 12, which improves the convenience of installation.
