[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a capacitor that can prevent detachment, including a protective shell 1, a sealing cover 2 disposed on the upper part of the protective shell 1, a capacitor body 4 installed inside the protective shell 1, and a connecting assembly 3 disposed outside the capacitor body 4. The connecting assembly 3 includes a disassembly and assembly mechanism 31 disposed inside the protective shell 1, a fixing mechanism 32 disposed on the outer side of the protective shell 1, and a mounting ring 311 fixedly connected to the inner wall of the protective shell 1. A limit groove 313 is formed in the inner wall of the mounting ring 311, a sealing ring 312 is fixedly connected to the upper part of the mounting ring 311, a limit block 314 is fixedly connected to the outer wall of the capacitor body 4, and an elastic pressing block 315 is fixedly installed at the bottom of the sealing cover 2. A positioning block 316 is fixedly connected to the outer wall of the cover 2. A slot 317 is opened on the outer wall of the sealing cover 2. A movable groove 318 is opened inside the top of the protective shell 1. A movable block 319 is slidably connected to the inner wall of the movable groove 318. A sloping locking block 3110 is fixedly connected to one side of the movable block 319. A connecting rod 3111 is fixedly connected to the inner wall of the movable groove 318. A knob is fixedly connected to the outer end of the connecting rod 3111. A first spring 3112 is fixedly connected to the inner wall of the movable groove 318. A positioning groove 3113 is opened on the inner wall of the protective shell 1. A fixing post 3114 is fixedly connected to the inner wall of the positioning groove 3113. An ejection ring 3115 is slidably connected to the outer wall of the fixing post 3114. A second spring 3116 is fixedly connected to the inner wall of the positioning groove 3113.

[0028] In this embodiment, the inclined plate block 3110 movably passes through the movable groove 318, and the inclined plate block 3110 is engaged with the groove 317. The first spring 3112, through the cooperation of the mounting ring 311, sealing ring 312, limiting groove 313, limiting block 314, elastic pressing block 315, positioning block 316, groove 317, movable groove 318, movable block 319, inclined plate block 3110, connecting rod 3111, first spring 3112, positioning groove 3113, fixing column 3114, ejection ring 3115, and second spring 3116, facilitates manual installation and disassembly of the capacitor body 4, thereby facilitating subsequent manual inspection and maintenance of the capacitor body 4, or direct replacement, thus increasing the applicability of the device.

[0029] Furthermore, one end of the first spring 3112 is fixedly connected to the movable block 319, the outer end of the connecting rod 3111 moves through the movable groove 318, and the limiting block 314 is adapted to the limiting groove 313.

[0030] Furthermore, there are two mounting blocks 324, symmetrically distributed at the lower part of the fixing ring 321.

[0031] In use, the capacitor body 4 is first manually placed into the protective shell 1. The limiting groove 313 and limiting block 314 facilitate manual installation and assembly of the positive and negative terminals of the capacitor body 4 with the protective shell 1. Then, the sealing cover 2 is manually inserted into the protective shell 1, and the positioning block 316, fixedly connected to the outer wall of the sealing cover 2, engages with the positioning groove 3113. The positioning block 316 is then fitted onto the outside of the fixing post 3114, thus limiting the position of the sealing cover 2. This facilitates the subsequent operation of the inclined plate 3110 and the slot 317. After the positioning block 316 and the slot 317 are engaged, the sealing cover 2 is manually pressed inward. When the sealing cover 2 enters the protective shell 1, the inclined plate 3110, due to its inclined upper part, can be pressed into the movable groove 318. At this time, the first spring 3112 is compressed, and when the sealing cover 2 is pressed downward, it can contact the sealing ring 312. The elastic pressing block 31, which is fixedly connected to the bottom of the sealing cover 2, is also in contact with the sealing ring 312. 5. The top of the capacitor body 4 can be limited. After the sealing cover 2 and the protective shell 1 are fully engaged, the first spring 3112, under the action of elastic force, can cause the movable block 319 to drive the inclined plate block 3110 to move outward, so that the inclined plate block 3110 can engage with the slot 317, thereby fixing the sealing cover 2 to the top of the protective shell 1. The installation operation is simple and convenient. By installing the capacitor body 4 inside the protective shell 1, the capacitor body 4 can be protected, increasing the service life of the capacitor body 4. Furthermore, when it is necessary to disassemble the capacitor body 4, simply squeeze the knob and pull the connecting rod 3111 outward, so that the movable block 319 fixed to the inner end of the connecting rod 3111 can drive the inclined plate block 3110 to move outward, thereby separating the inclined plate block 3110 from the slot 317. Then the sealing cover 2 can be taken out upward, which facilitates the manual disassembly of the capacitor body 4, and facilitates the subsequent manual inspection and maintenance of the capacitor body 4.

[0033] Based on Embodiment 1, a preferred embodiment of the capacitor that prevents detachment provided by this utility model is, for example... Figures 1 to 5 As shown: The fixing mechanism 32 includes a fixing ring 321 disposed outside the protective shell 1. A plastic ring 322 is fixedly connected to the inner wall of the fixing ring 321. A mounting post 323 is fixedly installed at the bottom of the fixing ring 321. A mounting block 324 is fixedly installed at the bottom end of the mounting post 323. A threaded hole 325 is opened on the surface of the mounting block 324.

[0034] In this embodiment, the top end of the second spring 3116 is fixedly connected to the ejector ring 3115, the positioning block 316 is adapted to the positioning groove 3113, and the positioning block 316 is slidably connected to the outer wall of the fixing post 3114. Through the cooperation of the fixing ring 321, the plastic ring 322, the mounting post 323, the mounting block 324, and the threaded hole 325, the protective shell 1 can be supported and fixed, thereby preventing the capacitor body 4 from falling off and providing a protective effect for the capacitor body 4.

[0035] After the capacitor body 4 is installed inside the protective shell 1, the capacitor body 4 is manually inserted into the fixing ring 321. Under the squeezing action of the plastic ring 322, the protective shell 1 can be fixed. Then, the mounting block 324 is manually placed at the upper end of the designated position and fixed to the upper part of the protective shell 1 through the threaded hole 325. This can fix the protective shell 1 and the capacitor body 4, thereby preventing the capacitor body 4 from falling off. The protective shell 1 can also protect the capacitor body 4, increasing the applicability of the device.
