[0033] Specifically, multiple anti-corrosion layers are formed by aluminum oxide film 3, epoxy resin paint layer 4 and silicone high-temperature resistant paint layer 5 to enhance the corrosion resistance to electrolyte. The sealing performance of the structure can be enhanced by the sealant layer 6, and its waterproof ability can be improved by the waterproof layer 7. The metal cylinder 8 can not only improve its strength but also provide partial shielding ability. The outer anti-shear layer 9 can play a certain role in preventing shearing.

[0034] Reference Figure 1 、 Figure 2 and Figure 5 The mounting mechanism 2 includes a conical block 201, which is slidably connected to the outer side of the end column 10. A soldering pen oil block 202 is provided in the middle of the inner wall of the conical block 201. A lead-free solder wire baffle 203 is fixedly connected to the bottom of the inner wall of the conical block 201. A circular ring 204 is fixedly connected to the outer bottom of the end column 10. An inclined plate 205 is fixedly connected to the outer side of the circular ring 204.

[0035] Specifically, when installed on a circuit board, the tilting plate 205 can facilitate the insertion of the end column 10 along the hole above the circuit board, and the conical block 201 can limit the position of the end column 10 inserted into the circuit board. When electric welding is used, its temperature is transferred to the inside through the conical block 201, so that the lead-free solder wire baffle 203 is dissolved, thereby welding the end column 10 to the circuit board, and the welding pen oil block 202 can make the welding more firm and durable.

[0036] Reference Figure 2 、 Figure 3 and Figure 5 , the outer side of the end column 10 is fixedly connected with an anti-rust layer 11, and the outer bottom of the two anti-rust layers 11 is fixedly connected with a buffer silica gel 12; the top of the left end column 10 is fixedly connected with a positive electrode block 14, and the top of the right end column 10 is fixedly connected with a negative electrode block 13; the adjacent sides of the two end columns 10 are fixedly connected with an L-shaped wire 15, and the front end of the L-shaped wire 15 is fixedly connected with a discharge lamp 16; the top of the waterproof layer 7 is fixedly connected with a heat insulation board 17, and the top of the heat insulation board 17 is provided with a plurality of heat dissipation holes 18; the middle part of the top of the heat insulation board 17 is fixedly connected with a card block 19, and the top of the card block 19 is provided with a U-shaped plate 20, and the left and right sides of the heat insulation board 17 are fixedly connected with fluorescent strips 21; the bottom of the waterproof layer 7 is fixedly connected with a cylinder 22, and the outer side of the cylinder 22 is provided with a plurality of dehumidification holes 23;

[0037] Specifically, the anti-rust layer 11 can prevent the end column 10 from rusting, the buffer silica gel 12 can reduce the transmission of vibration, the positive block 14 and the negative block 13 can facilitate people to distinguish and install, the discharge lamp 16 can release the electrical energy stored in the capacitor after power failure, the heat insulation board 17 can isolate the heat and discharge it through the heat dissipation holes 18 on the outside, the U-shaped plate 20 can mark the basic information of the capacitor, the fluorescent strip 21 can be used to remind people of the location of the capacitor, some dehumidification objects can be placed through the cylinder 22, and dehumidification can be better performed through the dehumidification hole 23.

[0038] Working Principle: Before use, the device is first constructed with a multi-layered anti-corrosion system consisting of an aluminum oxide film 3, an epoxy resin paint layer 4, and a silicone high-temperature resistant paint layer 5 to enhance its resistance to electrolyte corrosion. Simultaneously, a sealant layer 6 enhances the overall structural sealing. A waterproof layer 7 further improves the product's waterproofing capabilities. Furthermore, a metal cylinder 8 not only reinforces the structure but also provides shielding capabilities. The outer anti-shear layer 9 provides a protective shearing function to ensure the overall safety of the capacitor. During installation on the circuit board, the mounting mechanism 2 utilizes the tilting plate 205 to conveniently guide the terminal 10 into the correct alignment and insertion into the hole on the circuit board. Furthermore, the tapered block 201 limits the insertion position of the terminal 10 on the circuit board, ensuring precise installation. During welding, heat is efficiently transferred internally through the tapered block 201, causing the lead-free solder wire baffle 203 to melt, thereby achieving a secure bond between the terminal 10 and the circuit board. In addition, the welding pen oil block 202 enhances the firmness and durability of the welding, ensuring that the connection quality meets high standards.
