Description

Technical Field

[0001] This application relates to the field of capacitors, and more particularly, to a protective structure and a capacitor. Background Art

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between form a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conducting plate to the voltage between the two plates. The basic unit of the capacitance of a capacitor is the farad (F). In a circuit diagram, the capacitance element is usually represented by the letter C. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering. The tuning circuit of a transistor radio uses it, and the coupling circuit and bypass circuit of a color TV also use it.

[0003] When an existing cylindrical capacitor is collided during transportation, the outer shell of the cylindrical capacitor is easily punctured. After the outer shell of the capacitor is damaged, it cannot operate safely and affects normal use, resulting in a waste of resources. Therefore, a housing is installed on the outer surface of the capacitor to protect the capacitor components. For example, a capacitor with a protective housing disclosed in Chinese Patent Publication No. CN218414293U. This capacitor with a protective housing is composed of a protective bottom cover, a protective top cover, and protective pieces. The protective housing of the capacitor is formed by splicing four protective pieces. The four protective pieces are hinged to the side surface of the protective bottom cover. By rotating the protective top cover with the connecting strip, the four second hooks on its surface are respectively moved out from the first hooks inside the tops of the four protective pieces, and then the four protective pieces can be flipped open to remove the thermal grease inside them, which is convenient for the replacement operation of the thermal grease inside the capacitor protective housing. However, there is no cavity for air flow between the inside of the protective cover and the capacitor, resulting in poor heat dissipation effect when the protective cover protects the capacitor, which will further reduce the service life and safety performance of the capacitor. Summary of the Utility Model

[0004] To make up for the above deficiencies, this application provides a protective structure and a capacitor, aiming to improve the problem that the heat dissipation effect is poor when the protective cover protects the capacitor, which will further reduce the service life and safety performance of the capacitor.

[0005] On the one hand, an embodiment of this application provides a protective structure, including a protective component.

[0006] The protective component includes a protective cover with an open bottom. A fixed ear plate is fixedly connected to the bottom of the protective cover. A plurality of partition members are arranged in a circular array inside the protective cover. Each partition member forms a plurality of cavities inside the protective cover.

[0007] In a specific embodiment, a plurality of strip-shaped grooves are formed in an annular array on the side wall of the protective cover, and the outer sides of each partition member are respectively located inside each strip-shaped groove.

[0008] In a specific embodiment, each partition member includes a U-shaped partition. The connecting end of the U-shaped partition is fixedly connected to the inside of the strip-shaped groove, and the other two ends of the U-shaped partition are respectively located inside the protective cover. A plurality of cavities are formed inside the protective cover by a plurality of the U-shaped partitions.

[0009] In a specific embodiment, heat-conducting layers are provided at both ends of each U-shaped partition.

[0010] In a specific embodiment, an elastic connecting portion is provided between the U-shaped partition and the heat-conducting layer.

[0011] In a specific embodiment, mounting bolts are provided on the fixed ear plates.

[0012] In a specific embodiment, the top of the protective cover is open.

[0013] On the other hand, another capacitor is provided in an embodiment of the present application, including

[0014] The above-mentioned protection structure and the capacitor body.

[0015] The protective cover is sleeved on the outside of the capacitor body, and each partition member is in contact with the outer side wall of the capacitor body.

[0016] Beneficial effects: Through the arrangement of the partition members, a plurality of heat dissipation cavities are formed between the inner wall of the protective cover, the partition members and the outer wall of the capacitor body, so that the heat generated when the capacitor body operates can circulate and dissipate heat through each heat dissipation cavity, so that while protecting the capacitor body, its heat dissipation effect will not be affected, and the service life and safety performance of the capacitor body will not be affected.

[0024] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0025] Please refer to Figures 1 - 5 , the present application provides a protection structure, including a protection component 20.

[0026] Among them, the protection component 20 can protect the capacitor body 10 while not affecting the heat dissipation of the capacitor body 10, which can increase the practicability of the protection component 20.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, the protection component 20 includes a protective cover 210 with an open bottom. A fixed ear plate 220 is fixedly connected to the bottom of the protective cover 210. A number of partition members 240 are arranged in a circular array inside the protective cover 210, and each partition member 240 forms a number of cavities inside the protective cover 210. Among them, when it is necessary to protect the capacitor body 10, align the bottom of the protective cover 210 with the capacitor body 10 and downward to sleeved the protective cover 210 outside the capacitor body 10. At this time, each partition member 240 contacts the outer side wall of the capacitor body 10, so that a number of heat dissipation cavities are formed between the inner wall of the protective cover 210, the partition member 240 and the outer wall of the capacitor body 10. The fixed ear plate 220 is used for the installation of the protective cover 210. Through the arrangement of the partition member 240, a number of heat dissipation cavities are formed between the inner wall of the protective cover 210, the partition member 240 and the outer wall of the capacitor body 10, so that the heat generated when the capacitor body 10 operates can be circulated and dissipated through each heat dissipation cavity, so that while protecting the capacitor body 10, it will not affect its heat dissipation effect, and will not affect the service life and safety performance of the capacitor body 10.

[0028] In this embodiment, a number of strip-shaped grooves 250 are formed in a circular array on the side wall of the protective cover 210, and the outside of each partition member 240 is located inside each strip-shaped groove 250 respectively. Each partition member 240 includes a U-shaped partition 241. The connecting end of the U-shaped partition 241 is fixedly connected to the inside of the strip-shaped groove 250. Specifically, the U-shaped partition 241 can be made of a heat-conducting plate, with fast heat-conducting effect, which can quickly conduct the heat inside the protective cover 210. And the outside of the U-shaped partition 241 is on the same curved surface as the outer wall of the protective cover 210. Therefore, the U-shaped partition 241 is directly in contact with the outside air, thus further accelerating the heat dissipation effect of the capacitor body 10. The other two ends of the U-shaped partition 241 are respectively located inside the protective cover 210, and a number of cavities are formed inside the protective cover 210 through a number of U-shaped partitions 241. Heat-conducting layers 243 are provided at both ends of each U-shaped partition 241. Specifically, the heat-conducting layer 243 can be heat-conducting silicone grease to improve the heat-conducting effect. An elastic connecting part 242 is arranged between the U-shaped partition 241 and the heat-conducting layer 243. Specifically, the elastic connecting part 242 can be an elastic block with good heat-conducting effect, or made of other elastic materials with heat-conducting effect, so that the contact with the capacitor body 10 is flexible. On the one hand, it can prevent damage to the outer wall of the capacitor body 10, and on the other hand, when the specification of the capacitor body 10 changes slightly, it can provide protection for multiple specifications, improving the applicable range of the protective cover 210. Among them, when the heat-conducting layer 243 contacts the outer side wall of the capacitor body 10, the heat it dissipates is transmitted to the U-shaped partition 241. Since the U-shaped partition 241 is located inside the strip-shaped groove 250, the heat can be quickly dissipated, improving the heat dissipation efficiency of the capacitor body 10.

[0029] When specifically setting, mounting bolts 230 are provided on the fixed ear plate 220. Among them, through the mounting bolts 230 provided on the fixed ear plate 220, the installation of the protective cover 210 is realized, and thus the protection of the capacitor body 10 is realized.

[0030] In this embodiment, the top of the protective cover 210 is open.

[0031] Please refer to Figures 1 - 5 , another capacitor is provided in the embodiment of the present application, including the above-mentioned protection structure and the capacitor body 10.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the protective cover 210 is sleeved on the outside of the capacitor body 10, and each partition member 240 is in contact with the outer side wall of the capacitor body 10. Among them, the bottom of the protective cover 210 is aligned with the capacitor body 10, and then the protective cover 210 is sleeved on the outside of the capacitor body 10 downward. At this time, each partition member 240 is in contact with the outer side wall of the capacitor body 10, so that a plurality of heat dissipation cavities are formed between the inner wall of the protective cover 210, the partition member 240 and the outer wall of the capacitor body 10. The fixed ear plate 220 is used for the installation of the protective cover 210.

[0033] Working principle of the protection structure and the capacitor:

[0034] When it is necessary to protect the capacitor body 10, the bottom of the protective cover 210 is aligned with the capacitor body 10, and then the protective cover 210 is sleeved on the outside of the capacitor body 10 downward. At this time, each partition member 240 is in contact with the outer side wall of the capacitor body 10, so that a plurality of heat dissipation cavities are formed between the inner wall of the protective cover 210, the partition member 240 and the outer wall of the capacitor body 10. The fixed ear plate 220 is used for the installation of the protective cover 210. Through the arrangement of the partition member 240, a plurality of heat dissipation cavities are formed between the inner wall of the protective cover 210, the partition member 240 and the outer wall of the capacitor body 10, so that the heat generated when the capacitor body 10 operates can be circulated and dissipated through each heat dissipation cavity, so that while protecting the capacitor body 10, the heat dissipation effect is not affected, and the service life and safety performance of the capacitor body 10 are not affected.

[0035] The above are only embodiments of the present application and are not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
