[0002] Ultra-low temperature horn capacitors are a common type of aluminum electrolytic capacitor, mainly used in low-temperature environments.

During subsequent use, if a fault occurs inside the horn capacitor, the increased internal pressure can easily cause bulging.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. In this invention, when the internal pressure of the capacitor shell increases, the sensing component is first triggered to work. The sensing component drives the insulating conduit to slide upward, so that the top of the insulating conduit punctures the top of the capacitor shell at the cross buffer opening, and the top of the insulating conduit extends to the top of the capacitor shell. At the same time, the gas filtering component is triggered to neutralize the corrosive gas inside, and the driving component is triggered to work to disperse the neutralized liquid discharged from the drainage hole.
[0018] 2. When the sensing component is working in this invention, when the pressure inside the capacitor shell increases, it will lift the floating ring inside the capacitor shell upward. When the floating ring slides upward, it will drive the insulating conduit to slide upward through the connecting rod. When the insulating conduit slides upward, it will puncture the cross buffer opening, so that the top of the insulating conduit extends to the top of the capacitor shell. At the same time, when the insulating conduit slides upward, it will trigger the air filtering component to work.
[0019] 3. When the gas filtration assembly is working in this invention, after the insulating conduit slides upward, the bottom of the U-shaped flow channel slides to the side opening and communicates with it. The top of the U-shaped flow channel slides to the bottom of the annular plate and is opposite to the inner side of the glass fiber filter pad at the bottom of the annular plate. The bottom of the bent flow channel slides to the top of the annular plate and is opposite to the inner side of the glass fiber filter pad at the top of the annular plate. At this time, the top of the drainage hole slides to the bottom of the storage cavity and communicates with it. At this time, the neutralized solution inside the storage cavity can flow to the inner bottom surface of the capacitor shell through the drainage hole. When the gas is discharged from the gas filtration assembly, it will drive the drive assembly to work.
[0020] 4. When the drive component is working in this invention, the corrosive gas after passing through the filter gas component is discharged through the exhaust port in the gas chamber. When it is discharged, it will drive the vortex blades to rotate, which in turn drives the rotating shaft to drive multiple impact blades to rotate. When the multiple impact blades rotate, they can disperse the neutral liquid discharged from the drainage hole, so that it is evenly distributed at the bottom of the capacitor shell, preventing the corrosive liquid from flowing out from the bottom of the capacitor shell and causing corrosive damage to the printed circuit board.

A sealing plate 16 is provided at the bottom of the protective plate 15. The bottom of the outer sleeve 1 extends to the bottom of the sealing plate 16. A glass seal 17 is provided in the middle of the inner wall of the protective plate 15. An anode pin 10 is provided between the inner walls of the glass seal 17.

A negative electrode filler 13 is provided between the inner walls of the negative electrode sleeve 12.
[0033] A diaphragm 14 is provided between the inner walls of the negative electrode filler 13. The top of the diaphragm 14 is fixed to the inner top surface of the capacitor shell 11, and the bottom of the diaphragm 14 is sealed and fitted to the top of the protective plate 15. A current collector 20 is provided at the bottom of the base 26. A positive electrode filler 19 is provided between the outer surface of the current collector 20 and the inner wall of the diaphragm 14. A gap is left between the top of the positive electrode filler 19 and the inner top surface of the capacitor shell 11. The inner wall of the current collector 20 is slidably fitted to the outer surface of the insulating conduit 21. A bent copper strip 18 is fixed near the bottom edge of the outer surface of the current collector 20. The bottom end of the bent copper strip 18 is fixed to the top of the anode pin 10 near one side edge. Multiple side channels 40 are equidistantly opened along the circumferential direction on the outer surface of the positive electrode filler 19. The top and bottom of the multiple side channels 40 are respectively connected to the top and bottom of the positive electrode filler 19.
[0034] The effect achieved is that when the capacitor case 11 is mounted on the printed circuit board 2, the anode pin 10 is inserted into the socket 5, and the arc-shaped pin 9 is inserted into the arc-shaped opening 4. Through the mutual limiting of the arc-shaped pin 9 and the arc-shaped opening 4, the capacitor case 11 can be pre-positioned inside the soldering groove 3, which facilitates subsequent soldering. A neutralizing solution is injected into the storage cavity 24 inside the capacitor case 11, and at this time, the vent 38 is located above the neutralizing solution.

The tops are all located above the bottom of the bent flow channel 32. When a fault occurs inside the capacitor shell 11 and causes the capacitor to bulge, the pressure inside the capacitor shell 11 will increase and corrosive gas will be generated. When the pressure inside the capacitor shell 11 increases, the sensing component will be triggered to work first. The sensing component will drive the insulating conduit 21 to slide upward, so that the top of the insulating conduit 21 will puncture the top of the capacitor shell 11 at the cross buffer opening 25, so that the top of the insulating conduit 21 will extend to the top of the capacitor shell 11. At the same time, the gas filtering component will be triggered to neutralize the internal corrosive gas, and the drive component will be triggered to work to disperse the neutralized liquid discharged from the drainage hole 42.
[0035] like Figure 3 , Figure 6 and Figure 7 As shown, the sensing component includes a floating ring 28, which is located on top of the positive electrode filler 19. The outer surface of the floating ring 28 is slidably sealed to the inner wall of the capacitor shell 11, and the inner wall of the floating ring 28 is slidably sealed to the outer surface of the base 26. The outer surface of the insulating conduit 21 has multiple side openings 29 that extend into the interior at equal intervals along the circumferential direction.

One end of the connecting rod 30 is fixed to the inner wall of the floating ring 28, and the other end of the connecting rod 30 is fixed to the outer surface of the insulating conduit 21.
[0036] The effect is that when the internal pressure of the capacitor shell 11 increases, it will lift the floating ring 28 inside the capacitor shell 11 upward. When the floating ring 28 slides upward, it will drive the insulating conduit 21 to slide upward through the connecting rod 30. When the insulating conduit 21 slides upward, it will puncture the cross buffer port 25, so that the top of the insulating conduit 21 extends to the top of the capacitor shell 11. At the same time, when the insulating conduit 21 slides upward, it will trigger the air filter assembly to work.
[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the air filtration assembly includes an annular plate 33, which is disposed inside the disc-shaped cavity 27. The inner wall of the annular plate 33 is slidably and sealingly fitted with the outer surface of the insulating conduit 21. Glass fiber filter pads 34 are provided at both the top and bottom of the annular plate 33, and the two glass fiber filter pads 34 are respectively fitted to the inner top and bottom surfaces of the disc-shaped cavity 27. A neutralizing filler 35 is provided between the outer surface of the annular plate 33 and the inner wall of the disc-shaped cavity 27. The top and bottom of the neutralizing filler 35 are respectively connected to the glass fiber filter pads 34. The inner bottom of the disc-shaped cavity 27... An annular temporary storage groove 36 is provided near the inner edge of the air cavity 37. Multiple bent flow channels 32 are provided at equal intervals along the circumferential direction on the inner bottom surface of the air cavity 37. The bottom ends of the multiple bent flow channels 32 all penetrate to the outer surface of the insulating conduit 21. Multiple exhaust holes 38 are provided at equal intervals along the circumferential direction on the inner top surface of the air cavity 37. Multiple U-shaped flow channels 31 are provided at equal intervals along the circumferential direction on the inner wall of the insulating conduit 21. Both ends of the multiple U-shaped flow channels 31 penetrate to the outer surface of the insulating conduit 21, and the U-shaped flow channels 31 are located below the bent flow channels 32.
[0038] The effect achieved is that after the insulating conduit 21 slides upward, the bottom of the U-shaped flow channel 31 slides to the side opening 29 and communicates with it. The top of the U-shaped flow channel 31 slides to the bottom of the annular plate 33 and is opposite to the inner side of the glass fiber filter pad 34 at the bottom of the annular plate 33. The bottom of the bent flow channel 32 slides to the top of the annular plate 33 and is opposite to the inner side of the glass fiber filter pad 34 at the top of the annular plate 33. At this time, the top of the drainage hole 42 slides to the bottom of the storage cavity 24 and communicates with it. At this time, the neutralized solution inside the storage cavity 24 can flow through the drainage hole 42 to the inner bottom surface of the capacitor shell 11. When the gas is discharged from the gas filtration assembly, it will drive the drive assembly to work.
[0039] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the drive assembly includes a rotating shaft 22, which is located between the inner walls of the insulating conduit 21, and the outer surface of the rotating shaft 22 is slidably attached to the inner wall of the insulating conduit 21. An air cavity 37 is formed between the inner walls of the insulating conduit 21 near the top edge. The top of the rotating shaft 22 is rotatably connected to the inner top surface of the air cavity 37, and the bottom of the rotating shaft 22 extends to the bottom of the insulating conduit 21. Multiple vortex blades 39 are fixed at equal intervals along the circumferential direction on the outer surface of the rotating shaft 22 near the top edge. The multiple vortex blades 39 are all located inside the air cavity 37. Multiple striking blades 23 are fixed at equal intervals along the circumferential direction on the outer surface of the rotating shaft 22 near the bottom edge.
[0040] The effect achieved is that the corrosive gas enters the bottom of the U-shaped flow channel 31 through the side opening 29 inside the capacitor shell 11, and then enters the glass fiber filter pad 34 at the bottom of the annular plate 33 through the U-shaped flow channel 31. After being neutralized by the neutralizing filler 35, it is filtered through the glass fiber filter pad 34 at the top of the annular plate 33 and then enters the bottom of the bent flow channel 32. From the bent flow channel 32, it enters the gas chamber 37 and is discharged through the exhaust hole 38 in the gas chamber 37. When it is discharged, it will drive the vortex blades 39 to rotate, which in turn drives the rotating shaft 22 to drive multiple impact blades 23 to rotate. When the multiple impact blades 23 rotate, they can disperse the neutralized liquid discharged from the drainage hole 42, so that it is evenly distributed at the bottom of the capacitor shell 11, preventing the corrosive liquid from flowing out from the bottom of the capacitor shell 11 and causing corrosive damage to the printed circuit board 2.
[0041] Working principle: When using this device, when mounting the capacitor case 11 on the printed circuit board 2, insert the anode pin 10 into the socket 5, and simultaneously insert the arc-shaped pin 9 into the arc-shaped opening 4. Through the mutual limiting of the arc-shaped pin 9 and the arc-shaped opening 4, the capacitor case 11 can be pre-positioned inside the welding groove 3, facilitating subsequent welding. A neutralizing solution is injected into the storage cavity 24 inside the capacitor case 11, and at this time, the vent 38 is located above the neutralizing solution. The bottom end of the bent flow channel 32 is in contact with the inner side of the annular plate 33. The top of the U-shaped flow channel 31 is located at the side opening 29, and the bottom is in contact with the inner side of the base 26. Multiple drainage holes... The top of 42 is located above the bottom of the bent flow channel 32. When a fault occurs inside the capacitor case 11, causing the capacitor to bulge, the pressure inside the capacitor case 11 will increase and corrosive gas will be generated. When the pressure inside the capacitor case 11 increases, it will push the floating ring 28 inside the capacitor case 11 upward. When the floating ring 28 slides upward, it will drive the insulating guide tube 21 to slide upward through the connecting rod 30. When the insulating guide tube 21 slides upward, it will puncture the cross buffer opening 25, causing the top of the insulating guide tube 21 to extend to the top of the capacitor case 11. After the insulating guide tube 21 slides upward, the bottom of the U-shaped flow channel 31 will slide to the side opening 29, which is connected to the side opening 29. The top of the U-shaped flow channel 31 slides to the bottom of the annular plate 33, and is opposite to the inner side of the glass fiber filter pad 34 at the bottom of the annular plate 33. The bottom of the bent flow channel 32 slides to the top of the annular plate 33, and is opposite to the inner side of the glass fiber filter pad 34 at the top of the annular plate 33. At this time, the top of the drainage hole 42 slides to the bottom of the storage cavity 24, and is interconnected with the storage cavity 24. At this time, the neutralized solution inside the storage cavity 24 can flow to the inner bottom surface of the capacitor shell 11 through the drainage hole 42. The corrosive gas enters the bottom end of the U-shaped flow channel 31 through the side opening 29 inside the capacitor shell 11, and then enters the annular plate through the U-shaped flow channel 31. The liquid is placed in the glass fiber filter pad 34 at the bottom of the annular plate 33, and then neutralized by the neutralizing filler 35. After being filtered by the glass fiber filter pad 34 at the top of the annular plate 33, it enters the bottom of the bent flow channel 32 and enters the air chamber 37 from the bent flow channel 32. In the air chamber 37, it is discharged through the exhaust hole 38. When discharged, it will drive the vortex blades 39 to rotate, which in turn drives the rotating shaft 22 to drive multiple impact blades 23 to rotate. When the multiple impact blades 23 rotate, they can disperse the neutralized liquid discharged from the drainage hole 42, so that it is evenly distributed at the bottom of the capacitor shell 11, preventing corrosive liquid from flowing out from the bottom of the capacitor shell 11 and causing corrosive damage to the printed circuit board 2.
