Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a combined power capacitor. Background Technology

[0002] Power capacitors are a type of electrical component widely used in daily life. They are generally composed of a housing and electronic components and are used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium constitute a capacitor. The capacitance of a capacitor is determined by its geometric dimensions and the characteristics of the insulating medium between the plates. When a capacitor is used under AC voltage, its capacity is often expressed in terms of its reactive power.

[0003] In DC filter circuits, in order to provide a more stable current output, traditional capacitors generally only have two terminals. When facing different usage environments, multiple capacitors need to be prepared for series and parallel connection, which makes them inconvenient to use and therefore needs to be improved.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figure 1-3 As shown, one embodiment of this utility model provides a combined power capacitor, comprising:

[0030] Capacitor cell 1 includes capacitor body 11, terminal 12 and base 13;

[0031] The housing 2 has at least one placement cavity 21 inside, and the capacitor cell 1 can be fixed in the placement cavity 21.

[0032] Cover plate 3, the cover plate 3 is provided with lead-out unit 4 corresponding to each of the capacitor cells 1, the lead-out unit 4 can guide the terminal of the terminal 12 to the outside of the cover plate 3;

[0033] The limiting unit 5 is used to limit the capacitor body 11.

[0034] In this embodiment, by installing multiple capacitor cells 1 into the placement cavity 21 inside the housing 2 as required, and then using the lead-out unit 4 on the cover plate 3 to guide the terminal 12 to the outside of the cover plate 3, the series and parallel connection of multiple capacitor cells 1 is greatly facilitated, improving the ease of use. Furthermore, by limiting the capacitor body 11 through the limiting unit 5, the structural stability is provided, avoiding interference and collision between adjacent capacitor cells 1, and improving the safety of use.

[0035] It should be noted that the interior of the capacitor body 11 may contain metal plates and an insulating dielectric, and the capacitor cell 1 may be cylindrical, square, or other shapes. The terminals 12 used for electrical connections are typically bolts or pins, and may be single-ended, double-ended, or multi-ended to meet different wiring requirements. The base 13 not only provides physical support but also provides a stable contact surface during installation.

[0036] In one embodiment of the present invention, the lead-out unit 4 includes an inner terminal 41 and an outer terminal 42 that are interconnected. The inner terminal 41 is connected to the terminal block 12, and the outer terminal 42 is located outside the cover plate 3.

[0037] In this embodiment, the inner terminal 41 of the corresponding lead-out unit 4 can be connected by a wire, and then the line can be connected by the outer terminal 42, which makes the operation simpler and more convenient.

[0038] In one embodiment of this utility model, the limiting unit 5 includes:

[0039] The partition 51 has a first card plate 52 on both sides, and the first card plate 52 has a first card slot 53.

[0040] The second card plate 54 is disposed on the side wall of the housing 2, and the second card plate 54 is provided with a second card slot 55;

[0041] A limiting groove 56 is formed between the two first slots 53 of the partition 51, or between the first slot 53 and the second slot 55, and the capacitor cell 1 passes through the limiting groove 56.

[0042] In this embodiment, the partition 51 divides the internal space of the housing 2 into multiple placement cavities 21. The first retaining plates 52 and their first retaining slots 53 on both sides of the partition 51 work together with the second retaining plates 54 and their second retaining slots 55 fixed to the side wall of the housing 2. Specifically, the two first retaining slots 53 on adjacent partitions 51 are opposite each other to form a "clamping" space to clamp the capacitor body 11; or the first retaining slot 53 of one partition 51 is opposite to the second retaining slot 55 on the side wall to form a "clamping" space to clamp the capacitor body 11. In some implementations, the shape of the retaining slots can be V-shaped, U-shaped, or semi-circular, etc.

[0043] In one embodiment of this utility model, the bottom of the housing 2 is provided with a slot 23, and the partition 51 can be detachably inserted into the slot 23. During installation, simply insert the partition 51 vertically downward into the corresponding slot 23, and the partition 51 will be fixed and stand upright inside the housing 2. When it is necessary to change the configuration (such as increasing the number of units or changing the arrangement spacing), the partition 51 can be easily pulled out or inserted.

[0044] In one embodiment of this utility model, the first slot 53 and the second slot 55 are C-shaped. Optionally, the interior of the first slot 53 and the second slot 55 may be lined with a soft material (such as rubber) to increase friction and cushioning.

[0045] In one embodiment of this utility model, a latch 6 is provided on the outer side wall of the housing 2, and the bottom of the cover plate 3 is connected to the housing 2 through the latch 6. The latch 6 (such as a rotary buckle, spring latch, or lever lock) installed on the side wall of the housing 2 cooperates with the corresponding structure (such as a locking tongue, hook, or groove) designed on the bottom edge of the cover plate 3, and the cover plate 3 can be locked or released by simple operation (such as rotating the handle, pressing, or turning the lever). Its opening and closing operation is extremely quick and convenient, requiring no tools; the connection is firm and reliable, and can withstand a certain amount of vibration and impact; it is generally more time-saving than screw connections and has high maintenance efficiency.

[0046] In one embodiment of this utility model, the bottom of the placement cavity 21 is provided with an elastic buckle 22, and the base 13 is provided with a locking hole 14, the elastic buckle 22 cooperating with the locking hole 14. In this way, the capacitor cell 1 can be quickly positioned and fixed at the bottom of the placement cavity 21.

[0047] In one embodiment of this utility model, guide grooves 15 are provided at the upper and lower ends of the locking hole 14. The guide grooves 15 are designed as bevels or flared openings at the edges of the inlet (upper end) and outlet (lower end) of the locking hole 14. When the capacitor cell 1 falls, the bevel of the guide groove 15 can more easily guide the protrusion of the elastic buckle 22 into the locking hole 14. Similarly, when it is necessary to disassemble the capacitor cell 1, the guide groove 15 can also help the buckle protrusion slide out of the locking hole 14 more smoothly, avoiding hard jamming or damage to the buckle. This can significantly reduce the difficulty of installation and disassembly.

[0048] In one embodiment of this utility model, a lifting lug 7 is provided on the side wall of the capacitor body 11. This facilitates the handling and positioning of the capacitor unit 1 during assembly, transportation and maintenance. The lifting lug 7 can be designed as annular, U-shaped or with threaded holes. In some embodiments, the lifting lug 7 can be integrated into the base 13.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments are merely illustrative of several implementations of this utility model and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
