[0002] Capacitors, also known as capacitors, are also the main components of electronic circuits. Capacitors are mainly used for low-voltage powerless compensation and are used in power distribution facilities such as factories and shopping malls to correct power factors. They can also be used for three-phase filtering of inverter outputs and are used in frequency converters, photovoltaics and other fields.

[0003] The Chinese utility model patent with patent application number CN202023037325.7 provides a capacitor with a waterproof function. By setting a waterproof cover and an inner edge of the suit, the fixed base is surrounded by the waterproof cover for protection, so that the top of the outer shell can be waterproofed. The inner edge of the suit is arranged at the bottom inner side of the through hole of the waterproof cover, so that after the waterproof cover is put on, the inner edge of the suit can be meshed and connected with the serrated edge. The waterproof cover and the insulating cover can be effectively fitted to achieve a tight fit, preventing external water vapor from entering the internal capacitor, and is suitable for the production and use of capacitors with waterproof function.

[0004] However, during the use of the above equipment, it was found that when the staff inspected, repaired or replaced the capacitor, they needed to remove the fixing nails between the insulating sleeve and the top cover, and the bolts between the top cover and the shell one by one, and reinstall them after the repair and replacement. The structure of this equipment is relatively complex, and the disassembly and installation process is cumbersome, which is not conducive to the staff to work quickly. Utility Model Content

[0023] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0024] Example: As attached Figure 1 To Attachment Figure 6 As shown, a waterproof capacitor includes a protective shell 1, an interior of the protective shell 1 is provided with a mounting groove 14, a capacitor body 3 is mounted in the mounting groove 14, and the capacitor body 3 is adapted to the mounting groove 14.

[0025] A circular hole 12 is formed on the top of the protective shell 1 , a sealing ring 11 is installed on the inner wall of the circular hole 12 , and a connector 31 is provided on the top of the capacitor body 3 , and the connector 31 passes through the circular hole 12 .

[0026] The protective shell 1 is used to protect the capacitor body 3. The protective shell 1 covers the capacitor body 3, which can reduce the impact of the external environment on the capacitor body 3 and prevent liquid from adhering to the capacitor body 3. The sealing ring 11 set in the circular hole 12 can effectively prevent liquid from penetrating into the protective shell 1 from the circular hole 12, thereby achieving the purpose of waterproofing.

[0027] The bottom of the protective shell 1 is installed in the base 2, and a fixing hole 26 is provided on the inner wall of the base 2. A mounting hole 16 is provided at the bottom of the protective shell 1, and a mounting block 13 is installed inside the mounting hole 16. A spring 15 is fixedly connected to one end of the mounting block 13. The mounting block 13 is connected to the inner wall of the mounting hole 16 through the spring 15, and the mounting block 13 is adapted to the fixing hole 26.

[0028] When installing the capacitor body 3, install the capacitor body 3 in the installation groove 14, align the groove with the base 2 for installation, and when pressing the protective shell 1 downward, the installation block 13 at the bottom of the protective shell 1 contacts the base 2, and when moving downward, the base 2 squeezes the installation block 13, so that the installation block 13 squeezes the spring 15 and retracts into the installation hole 16 at the same time, and when the installation hole 16 moves downward to correspond to the fixing hole 26, the spring 15 in the installation hole 16 pushes the installation block 13 into the fixing hole 26, thereby realizing the rapid installation of the capacitor body 3 and the protective shell 1.

[0029] The fixed hole 26 is connected to the movable hole 25, and a button 23 is installed inside the movable hole 25. The middle diameter of the button 23 is larger than the diameters at both ends. The middle of the button 23 fits with the movable hole 25, and one end of the button 23 close to the mounting block 13 is arranged in the fixed hole 26. The button 23 is connected to the inner wall of the movable hole 25 through a spring 24.

[0030] A lifting plate 21 is arranged in the middle of the base 2 , the bottom of the lifting plate 21 is connected to the base 2 via a spring 22 , and the lifting plate 21 fits against the inner wall of the base 2 .

[0031] A sealing ring 2 4 is provided on the top of the base 2 , and the sealing ring 2 4 fits with the protective shell 1 .

[0032] The sealing ring 2 4 is arranged at the connection between the top of the base 2 and the protective shell 1, which can further seal the inside of the protective shell 1 to prevent liquid from entering the inside of the protective shell 1 from the connection between the base 2 and the protective shell 1, and can further improve the waterproof effect of the device;

[0033] When the protective shell 1 and the capacitor body 3 are installed, when the protective shell 1 moves downward in the base 2, it will squeeze the lifting plate 21 and at the same time squeeze the spring three 22, causing the spring three 22 to undergo elastic deformation;

[0034] When the capacitor body 3 needs to be inspected and repaired, the button 23 is pressed to move the button 23 along the movable hole 25, pushing the mounting block 13 out of the fixing hole 26 and retracting it into the mounting hole 16. At the same time, the spring three 22 can be restored to its original state, so that the protective shell 1 and the capacitor body 3 move upward under the push of the spring three 22, so that the capacitor body 3 can be quickly detached from the base 2, which is convenient for the staff to quickly carry out maintenance work. The function of the spring two 24 in the movable hole 25 is to push the button 23 to extend out to the outside of the base 2, which is convenient for the staff to press, and at the same time avoids the button 23 from blocking the mounting block 13, causing the mounting block 13 to be unable to enter the fixing hole 26.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
