Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a multi-core power capacitor. Background Technology

[0002] Multi-core capacitors are installed as a set, making installation and operation simple. Assembling multiple capacitors also reduces the space occupied during use and transportation.

[0003] In related technologies, a search revealed a solution for a multi-core combined capacitor (publication number CN219143986U). This solution integrates multiple capacitor cores, a common lead, and multiple independent leads inside the housing to achieve various capacitance options without the need to combine and use multiple single-core capacitors. This eliminates the need for complex and cumbersome installation operations. The structure is compact, occupies little space, and can significantly reduce product costs.

[0004] However, the above solution encapsulates multiple capacitor core components in a housing, resulting in a relatively concentrated heat generation from multiple capacitor core components, which may lead to thermal breakdown, short circuit, or even fire, especially in enclosed or high-temperature environments where the risk is exacerbated. When multiple capacitors are used in series or parallel, each capacitor is fixed independently, which is inconvenient for combining capacitors. Utility Model Content

[0005] The purpose of this invention is to provide a multi-core power capacitor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-core power capacitor, including a casing, a partition seat inside the casing, a plurality of cores inserted into the partition seat in the casing, and a heat-conducting block filling the space between the casing and the cores to quickly conduct the heat of the cores to the casing, resulting in fast heat conduction and preventing heat accumulation.

[0007] The conductive element is placed in the housing and connected to the separator. The conductive element conducts the heat of the core and the separator to the housing, accelerates the heat dissipation, protects the core, and thus improves the safety of the capacitor.

[0008] A cover is fixedly connected to a housing, and the cover is connected to a connector, which is electrically connected to the core package;

[0009] The assembly base includes several units, each equipped with a locking strip. The locking strip secures the assembly base to the housing. Adjacent assembly bases are joined together using assembly components. Fixing holes are provided at the corners of the assembly bases, allowing multiple capacitors to be arranged and combined conveniently and quickly.

[0010] Furthermore, the conductive component includes a support plate and a heat-conducting column connected to the support plate. The heat-conducting column is inserted into the middle of the separator seat. The support plate, heat-conducting column, and heat-conducting block quickly conduct the heat of the separator seat to the casing, avoiding heat accumulation in the core package and excessive temperature, preventing thermal breakdown of the core package, slowing down the aging process of the core package, and thus extending the service life of the capacitor.

[0011] Furthermore, the core package is electrically connected to a junction box, which is electrically connected to the connector. The junction box includes a metal sleeve and a junction ring that plugs into the metal sleeve. The junction ring and the metal sleeve are stably connected, which facilitates the electrical connection of multiple core packages and reduces the likelihood of poor contact.

[0012] Furthermore, the connector includes a threaded tube with a screw threaded into it and a wire welded to it. The wire is wound around the screw and tightened, making wiring convenient.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The separator separates the core to avoid heat accumulation. The heat conduction block and support plate conduct heat to the casing to avoid excessive temperature in the casing, prevent the capacitor from thermal breakdown, short circuit and other problems, make it safer to use, and maintain the stability of capacitor performance.

[0015] (2) The combination seat is fixed by the clamping strip, which is not easy to loosen. Adjacent combination seats can be quickly combined by trapezoidal slots and trapezoidal blocks. Not only is it easy to disassemble and assemble, but it also does not require tools such as screwdrivers. If a capacitor is damaged, it can be directly pulled out and replaced. The capacitor combination is highly flexible. Attached Figure Description

[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.

[0023] Example:

[0024] Please see Figure 1-5 This utility model provides a technical solution: a multi-core power capacitor, including a housing 5, with a partition seat 18 inside the housing 5, and a plurality of cores 11 inserted into the partition seat 18 installed in the housing 5. The partition seat 18 prevents the cores 11 from sticking together and prevents the heat generated by the cores 11 from accumulating together. A heat-conducting block 19 is filled between the housing 5 and the cores 11. The heat-conducting block 19 can quickly conduct the heat of the cores 11 to the housing 5, preventing the heat inside the housing 5 from being too concentrated, preventing the capacitor from thermally breaking down, and also extending the service life of the capacitor.

[0025] A heat transfer element is placed in the housing 5 and connected to the partition seat 18. The heat transfer element conducts heat from the core package 11 and the partition seat 18 to the housing 5, thereby improving the efficiency of heat transfer in the housing 5.

[0026] The cover 6 is fixedly connected to the housing 5. The cover 6 is connected to a connector, which is electrically connected to the core package 11. The capacitor is connected to the circuit through the connector.

[0027] Combination base 1, several of which are provided, and each combination base 1 has a clamping strip 3. The combination base 1 is fitted with the housing 5 through the clamping strip 3. Adjacent combination bases 1 are spliced ​​together by assembly parts. The corner of the combination base 1 is provided with a fixing hole 4, and the combination base 1 can be connected by screws 9 passing through the fixing hole 4. The capacitors are assembled by splicing, so as to realize the orderly arrangement of the capacitors and make it easier to organize the capacitors.

[0028] In this embodiment, as Figure 2As shown, the upper surface of the casing 5 has a recessed ring 16. The casing 5 is secured to the cover 6 by the recessed ring 16. The recessed ring 16 can position the cover 6 and achieve a sealed connection between the cover 6 and the casing 5, preventing water and dust from entering the casing 5.

[0029] In this embodiment, as Figure 3 and Figure 5 As shown, the conductive component includes a support plate 12 and a heat-conducting column 13 connected to the support plate 12. The heat-conducting column 13 is inserted into the middle of the partition seat 18 and conducts heat to the middle of the partition seat 18, guiding the heat to the support plate 12. The support plate 12 fits against the shell 5 and finally conducts the heat to the shell 5.

[0030] In this embodiment, as Figure 1 As shown, the surface of the cover 6 is provided with an explosion-proof valve 7. The structural strength of the area where the explosion-proof valve 7 is located is weaker than that of other areas of the cover 6. When the core package 11 is accidentally broken, causing the internal pressure of the casing 5 to increase, the explosion-proof valve 7 will break and release the pressure of the casing 5, thus preventing the casing 5 from exploding.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, the core package 11 is electrically connected to a power connection group, which is electrically connected to a connector. The wire connected to the connector is connected to the core package 11 to ensure that the capacitor functions properly.

[0032] In this embodiment, as Figure 3 As shown, the power connection group includes a metal sleeve 14 and a power connection ring 15 that is inserted into the metal sleeve 14. Two power connection rings 15 are provided with different sizes to ensure that the positive and negative poles of the core package 11 will not be short-circuited, making it safer to use.

[0033] In this embodiment, as Figure 3 As shown, the connector includes a threaded tube 8, a screw 9 is screwed into the threaded tube 8, and a wire 17 is welded to the threaded tube 8. The wire is wound around the screw 9, and the screw 9 is tightened in the threaded tube 8 to press the wire. The wiring is convenient and it is also convenient to connect multiple capacitors in series.

[0034] In this embodiment, as Figure 1 As shown, the assembly includes a trapezoidal block 10 and a trapezoidal groove 2. The assembly seat 1 is engaged with the trapezoidal groove 2 of another assembly seat 1 through the trapezoidal block 10. The assembly seat 1 is easy to assemble, so the arrangement of the housing 5 is also very convenient.

[0035] Specifically, during use, after loosening screw 9, the wire is wound around screw 9, and screw 9 is tightened to connect the capacitor to the circuit. The threaded tube 8 is connected to the core package 11 through wire 17, contact ring 15, and metal sleeve 14 to ensure that multiple core packages 11 can work normally.

[0036] The heat emitted by the core package 11 is conducted to the partition seat 18, the heat-conducting block 19, and the support plate 12, and finally to the shell 5, which avoids heat accumulation in the shell 5. The heat is discharged quickly, preventing the core package 11 from overheating and being damaged.

[0037] When the housing 5 is inserted into the combination seat 1, the clamping strip 3 presses against the housing 5, improving the stability of the connection between the housing 5 and the combination seat 1. Adjacent combination seats 1 are spliced ​​together through trapezoidal grooves 2 and trapezoidal blocks 10 to realize the combined use of multiple capacitors, which is convenient and quick to use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
