Description

Technical Field

[0002] A capacitor consists of two conductors placed close together with a non-conductive insulating medium in between. When a voltage is applied between the two plates of a capacitor, it stores electrical charge. It plays an important role in circuits such as tuning, bypassing, coupling, and filtering. In fact, capacitors are used in almost anything related to electricity.

[0003] During installation, most existing capacitors are sealed with a single sealing ring, which is not very effective. This allows moisture from the outside air to easily seep in through the gaps in the casing, causing damage to the capacitor. During transportation and installation, the internal components of the capacitor are also susceptible to impact damage. Utility Model Content

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figures 1 to 7 As shown, the present invention can be implemented through the following embodiments: A capacitor includes a housing 1 and a core 2. The core 2 is installed inside the housing 1. A mounting part 11 is provided at the top of the housing 1. A sealing plate 3 is installed on the mounting part 11. A buffer part 12 is provided at the bottom of the housing 1. A buffer seat 4 is connected to the buffer part 12. A mounting groove 41 is opened in the buffer seat 4. A spring 42 is installed in the mounting groove 41. A connecting plate 13 is provided on the buffer part 12. A mating plate 43 is provided on the buffer seat 4. A fixing post 5 is provided between the mating plate 43 and the connecting plate 13.

[0017] The sealing plate 3 seals the housing 1 by cooperating with the mounting part 11 to prevent humid air from entering the housing 1; the buffer part 12 cooperates with the buffer seat 4 to guide the buffering direction, and at the same time, the spring 42 installed inside the mounting groove 41 buffers the housing 1 to prevent the housing 1 and the core 2 from being damaged by impact; the connecting plate 13 and the mating plate 43 are connected by the fixing column 5 to limit the displacement of the housing 1 and prevent the housing 1 from falling off the buffer seat 4.

[0018] like Figure 2 As shown, a top plate 44 is provided on the spring 42, and the top plate 44 contacts the buffer part 12. The top plate 44 is used to separate the spring 42 and the housing 1, so that the spring 42 is not worn when the housing 1 rotates.

[0019] like Figure 1 and Figure 2 As shown, a sealing portion 31 protrudes from the sealing plate 3, and a sealing ring 32 is installed on the sealing portion 31. A bolt 6 passes through the sealing plate 3 and the mounting portion 11. The sealing portion 31 is used to mate with the housing 1, increasing the mating surface between the sealing plate 3 and the housing 1 and enhancing the sealing performance. The sealing ring 32 is used to fill the gap between the sealing portion 31 and the housing 1, enhancing the sealing performance. The bolt 6 is used to fix the sealing plate 3 and the housing 1, ensuring that the housing 1 and the sealing plate 3 are detachably connected.

[0020] like Figure 2 and Figure 7 As shown, a protruding ring 34 is provided on the sealing plate 3, and a corresponding groove 111 is provided on the mounting part 11. A sealing gasket 341 is installed between the protruding ring 34 and the groove 111. The protruding ring 34 is used to cooperate with the groove 111 to increase the mating surface between the sealing plate 3 and the housing 1 and enhance the sealing performance; the sealing gasket 341 is used to fill the gap between the groove 111 and the protruding ring 34 to strengthen the sealing performance.

[0021] like Figure 1 , Figure 2 and Figure 6 As shown, the fixing post 5 includes a fixing sleeve 51 and a fixing rod 52. The fixing rod 52 is provided with a first thread 521, the fixing sleeve 51 has a screw hole 511, and the fixing post 5 is provided with a second thread 512. The fixing post 5 is divided into a fixing sleeve 51 and a fixing rod 52 for easy disassembly and replacement. It can also be installed after the housing 1 and the buffer seat 4 are connected, which facilitates assembly. The first thread 521 and the screw hole 511 cooperate to fix the fixing sleeve 51 and the fixing rod 52. The second thread 512 is used to fix the fixing sleeve 51 and the docking plate 43 for easy assembly and disassembly.

[0022] like Figure 1 and Figure 3 As shown, there are four fixing posts 5 distributed at equal intervals around the docking plate 43. The docking plate 43 has fixing holes 431 between the fixing posts 5. The four fixing posts 5 distributed at equal intervals around the docking plate 43 facilitate the rotation of the housing 1 by cooperating with the slider 15 and the slide groove 45, so that the fixing posts 5 can connect the docking plate 43 and the connecting plate 13. The fixing holes 431 are used to fix the buffer seat 4 in the installation position through the connector.

[0023] like Figure 2 and Figure 3 As shown, a slider 15 is provided at the bottom of the housing 1, and a groove 45 is provided in the buffer seat 4. A limiting groove 46 is connected to the groove 45. The slider 15 and the groove 45 cooperate to allow the housing 1 to slide into the limiting groove 46 after rotating 90°. The slider 15 slides in the limiting groove 46 and, together with the fixing rod 52, fixes the housing 1 and the buffer seat 4 to prevent the connecting plate 13 from impacting the fixing rod 52 when subjected to vibration, thus preventing damage to the fixing rod 52.

[0024] As shown in the figure, a fixing groove 33 is provided on the sealing plate 3, and a protective sleeve 7 is installed on the mounting groove 41. The protective sleeve 7 covers the pin 21. A first seal 71 is installed between the protective sleeve 7 and the pin 21, and a second seal 72 is installed between the protective sleeve 7 and the fixing groove 33. The protective sleeve 7 and the sealing plate 3 are fixed together by screws 73. The protective sleeve 7 is fixed to the fixing groove 33 by screws 73, which facilitates disassembly and replacement and protects the pin 21 from breakage. The first seal 71 is used to fill the gap between the pin 21 and the protective sleeve 7 to prevent humid air from entering. The second seal 72 is used to fill the gap between the fixing groove 33 and the protective sleeve 7.

[0025] The working principle of this utility model is as follows: the protective sleeve 7 seals the pin 21 and the protective sleeve 7 through the sealing element 1 71 and the sealing element 2 72, as well as the gap between the fixing groove 33 and the protective sleeve 7, to prevent humid air from entering from the pin 21; the groove 111, the sealing gasket 341, the protruding ring 34 and the sealing ring 32 enhance the sealing between the sealing plate 3 and the housing 1, preventing humid air from entering from between the sealing plate 3 and the housing 1.

[0026] Insert the slider 15 on the housing 1 into the slide groove 45 and rotate it 90° along the slide groove 45, so that the slider 15 is pushed into the limiting groove 46 by the spring 42. At the same time, insert the fixing sleeve 51 from the bottom of the connecting plate 43, and then insert the fixing rod 52 into the top of the connecting plate 13 to complete the connection between the fixing rod 52 and the fixing sleeve 51. When the capacitor is impacted, the housing 1 slides along the buffer seat 4, and the spring 42 and the top plate 44 bear and absorb the impact, preventing the vibration from damaging the capacitor.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0028] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
