Description

Technical Field

[0001] The present application relates to the technical field of capacitors, and in particular to a solid electrolyte aluminum electrolytic capacitor. Background Art

[0002] Solid electrolyte aluminum electrolytic capacitors are also called solid-state capacitors. The biggest difference between them and ordinary capacitors is that they use different dielectric materials. The dielectric material of liquid aluminum capacitors is electrolyte, while the dielectric material of solid capacitors is conductive polymer material. In view of the many problems of liquid electrolytic capacitors, solid aluminum electrolytic capacitors came into being.

[0003] However, during the use of capacitors, short circuits may occur in the capacitors. Short circuits cause excessive current in the circuit, increasing the temperature and pressure inside the capacitor, which can easily cause the capacitor to explode. In addition, if the polarity of the capacitor is reversed during installation, the voltage on the circuit board will be too high, and a large current will be formed on the capacitor, causing the capacitor to heat up extremely quickly, causing the internal electrolyte to decompose and fail, causing the circuit to malfunction. Therefore, it is necessary to eliminate the faulty capacitors in the circuit. However, when eliminating faulty capacitors, the staff needs to use a multimeter to check the capacitors in the circuit one by one, which is time-consuming and laborious. Summary of the invention

[0040] The embodiment of the present application discloses a solid electrolyte aluminum electrolytic capacitor. By setting a hidden reflector mechanism 4 and a temperature sensing mechanism 6, the temperature sensing mechanism 6 detects the temperature change of the core package 2. When the capacitor is short-circuited or damaged, the temperature of the core package 2 rises rapidly, and the temperature sensing mechanism 6 drives the reflector 402 in the hidden reflector mechanism 4 to be exposed to show that the capacitor is damaged, which effectively solves the problem that damaged capacitors are difficult to find in the prior art and realizes simple and accurate finding of damaged capacitors.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] like Figures 1 to 9 As shown, a solid electrolyte aluminum electrolytic capacitor provided by the present invention includes a shell 1, a core package 2 is arranged in the shell 1, an electrode rod 3 is arranged on the core package 2, and the electrode rod 3 extends to the outside of the shell 1, wherein the shell 1 is a closed barrel structure, the electrode rod 3 includes a cathode rod and an anode rod, and the cathode rod and the anode rod are separated by an insulator.

[0043] On this basis, if Figures 2 to 5 As shown, the present embodiment further includes a reciprocating ventilation heat conduction mechanism 5 and a temperature sensing action mechanism 6, wherein the reciprocating ventilation heat conduction mechanism 5 is arranged inside the outer shell 1, and the temperature sensing action mechanism 6 can detect the temperature of the core package 2, and the reciprocating ventilation heat conduction mechanism 5 is in contact with the core package 2 and receives the heat transferred by the core package 2, and at the same time, a sealing plug 502 is slidably arranged in the heat conduction channel 501, and the sealing plug 502 is connected to the output component of the temperature sensing action mechanism 6.

[0044] like Figure 5 As shown, the temperature sensing mechanism 6 is arranged in the gap between the core package 2 and the shell 1. The temperature sensing mechanism 6 can detect the temperature of the core package 2. When the capacitor is working, the temperature of the core package 2 will rise, and the temperature sensing mechanism 6 will be actuated when the temperature of the core package 2 rises, driving the sealing plug 502 to slide in the heat conduction channel 501, thereby attracting air into the heat conduction channel 501, or discharging the air in the heat conduction channel 501, to achieve heat exchange between the heat conduction channel 501 and the outside world, so as to reduce the temperature of the core package 2.

[0045] Furthermore, if Figure 2 and Figure 5As shown, the present embodiment further includes a hidden reflector mechanism 4, which is arranged on the surface of the housing 1 and has a reflective surface 401. The reflective surface 401 is hidden when the capacitor is working normally, and when the capacitor is damaged, the reflective surface 401 will be exposed on the surface of the housing 1. When the staff checks the capacitor, when using a flashlight or other light-emitting tool to illuminate the capacitor to be inspected, the reflective surface 401 will reflect the light, thereby marking the location of the damaged capacitor, making it convenient for the staff to quickly and easily find the damaged capacitor.

[0046] In this embodiment, the hidden reflector mechanism 4 and the reciprocating ventilation and heat conduction mechanism 5 are both connected to the temperature sensing action mechanism 6. The temperature sensing action mechanism 6 detects the temperature change of the core package 2 and controls the actions of the hidden reflector mechanism 4 and the reciprocating ventilation and heat conduction mechanism 5 according to the temperature change speed.

[0047] When the capacitor is working, the temperature of the core package 2 will rise. When the capacitor is intact, the temperature change rate of the core package 2 is normal. When the capacitor is short-circuited or otherwise damaged, the temperature of the core package 2 will rise rapidly in a short time, that is, the temperature change of the core package 2 is abnormal.

[0048] Therefore, when the temperature sensing mechanism 6 detects that the temperature of the core package 2 rises normally, it controls the reciprocating ventilation and heat conduction mechanism 5 to operate, and drives the sealing plug 502 to slide in the heat conduction channel 501 to attract outside air into the heat conduction channel 501, thereby enhancing the heat absorption and heat dissipation effect of the reciprocating ventilation and heat conduction mechanism 5, and realizing the cooling treatment of the core package 2. When the temperature sensing mechanism 6 detects that the temperature of the core package 2 rises abnormally and rapidly, it controls the hidden reflector mechanism 4 to operate, so that the reflective surface 401 is exposed to display the position of the capacitor, thereby facilitating the staff to quickly and easily find the damaged capacitor.

[0049] Specifically, Figure 2 As shown, in this embodiment, a partition 101 is provided inside the shell 1, and the partition 101 divides the inner cavity of the shell 1 into a capacitor cavity 102 and a reflective cavity 103. The core package 2 is installed in the capacitor cavity 102, and the hidden reflector mechanism 4 and the temperature sensing action mechanism 6 are installed in the reflective cavity 103. The hidden reflector mechanism 4 includes a reflector 402, and the upper surface of the reflector 402 is a reflective surface 401, and a reflective sticker 403 is provided on the reflective surface 401.

[0050] Among them, Figure 5 and Figure 7As shown, a light-transmitting hole 104 is provided on the surface of the housing 1, a reflector 402 is located directly below the light-transmitting hole 104, and a shading plate 404 is provided above the reflector 402. When the shading plate 404 moves to directly above the reflector 402, the shading plate 404 blocks the reflector 402. When the shading plate 404 is moved away, external light can shine on the reflective sticker 403 of the reflector 402 to show the position of the capacitor.

[0051] In this embodiment, the shading plate 404 is connected to the output component of the temperature sensing mechanism 6. In the initial state, the shading plate 404 is located directly above the reflector 402 to block external light. Therefore, when the capacitor is intact, no reflection will occur when external light shines on the capacitor, indicating that the capacitor is intact. When the capacitor is damaged, the output component of the temperature sensing mechanism 6 will push the shading plate 404 to move to the upper side of the reflector 402, no longer shielding the reflector 402, and external light can shine on the reflective sticker 403 of the reflector 402 to indicate that the capacitor is damaged. In this way, when the staff uses a flashlight to shine on the circuit board, they can easily and accurately find the damaged capacitor.

[0052] Specifically, Figure 5 and Figure 7 As shown, in the present embodiment, the temperature sensing action mechanism 6 includes an expansion chamber 601, which is arranged on the top wall of the reflective cavity 103, and is filled with expansion gas. An expansion pipe 602 is arranged in the expansion chamber 601, and the expansion pipe 602 extends out of the expansion chamber 601 and an expansion piston 603 is slidably arranged in the expansion pipe 602. The expansion piston 603 is connected to an expansion connecting rod 604, and the expansion connecting rod 604 extends out of the expansion pipe 602.

[0053] Furthermore, a heat-conducting device is provided in the expansion chamber 601, which is connected to the core package 2 and receives the heat transferred by the core package 2. Therefore, when the capacitor is working and the core package 2 generates heat, the expansion chamber 601 will slowly receive the heat. The expansion chamber 601 is filled with expansion gas, and the thermal expansion coefficient of the expansion gas is relatively high. After the expansion chamber 601 receives the heat, the temperature of the expansion gas therein rises, the volume increases, and a greater air pressure is generated, thereby pushing the expansion piston 603 to slide in the expansion pipe 602, driving the expansion connecting rod 604 to move outward.

[0054] Furthermore, if Figure 5 and Figure 7As shown, the temperature sensing mechanism 6 also includes a driving seat 605 disposed below the expansion chamber 601, the upper end of the driving seat 605 is connected to the bottom surface of the expansion chamber 601 through a bracket, and the lower surface of the driving seat 605 is provided with a driving slide 606, in which a driving slide 607 is slidably disposed, and the driving slide 607 is connected to the shading plate 404 through a push rod 608. The driving slide 607 is connected to the expansion connecting rod 604, and when the expansion connecting rod 604 moves outward, the driving slide 607 can be driven to move, thereby driving the reflector 402 to move, and changing the relative position between the shading plate 404 and the reflector 402.

[0055] In this embodiment, if Figure 6 As shown, the reciprocating ventilation heat conduction mechanism 5 includes a heat conduction pipe 503 spirally wound on the outer periphery of the core package 2, a heat conduction channel 501 is arranged in the heat conduction pipe 503, the lower end of the heat conduction pipe 503 extends out of the outer shell 1, and the upper end of the heat conduction pipe 503 extends into the reflective cavity 103, the upper end of the heat conduction pipe 503 is connected with a pull-out channel 504 and a heat conduction member 505, the heat conduction member 505 extends into the expansion chamber 601, and the sealing plug 502 is movably arranged in the pull-out channel 504.

[0056] The sealing plug 502 is connected to the expansion connecting rod 604. When the expansion connecting rod 604 moves outward, the sealing plug 502 also moves in the pulling channel 504, attracting external air into the heat conduction channel 501, enhancing the heat absorption and heat dissipation effect of the reciprocating ventilation and heat conduction mechanism 5, and realizing the cooling treatment of the core package 2.

[0057] Furthermore, in the present embodiment, the interior of the driving slide 607 is hollow and is a non-Newtonian fluid chamber 609, which is filled with a non-Newtonian fluid. A resistance rod 610 is passed through the non-Newtonian fluid chamber 609, and the resistance rod 610 is immersed in the non-Newtonian fluid. One end of the resistance rod 610 extends out of the non-Newtonian fluid chamber 609 and is connected to an L-shaped connecting rod 611, which is connected to the sealing plug 502.

[0058] Based on the above settings, Figure 5 and Figure 7 As shown, the reciprocating ventilation and heat conduction mechanism 5 also includes a driving plate 506, which is connected to the driving seat 605 and is horizontally arranged above the resistance rod 610. A driving groove 507 is penetrated by the driving plate 506, and a driving screw 508 is horizontally penetrated in the driving groove 507. The driving screw 508 is a reciprocating screw and is provided with a screw nut seat 509. The screw nut seat 509 is connected to the resistance rod 610 through a support rod. When the driving screw 508 rotates, it can drive the screw nut seat 509 to translate, thereby driving the resistance rod 610 to move, and a screw bevel gear 510 is provided on the driving screw 508.

[0059] Furthermore, if Figure 8 and Fig. 9 As shown, a driving frame 511 is arranged on the side of the driving seat 605, and a driving gear 512 and a transmission bevel gear 513 are arranged on the driving frame 511. The driving gear 512 and the transmission bevel gear 513 are connected by a synchronous belt 514. The transmission bevel gear 513 is meshed with the lead screw bevel gear 510. The expansion connecting rod 604 is connected with an L-shaped transmission rod 515. The bottom surface of the L-shaped transmission rod 515 is arranged with a driving rack 516, and the driving rack 516 is meshed with the driving gear 512.

[0060] In this way, when the expansion link 604 moves outward, it can drive the L-shaped transmission rod 515 and the driving rack 516 to move. The movement of the driving rack 516 drives the driving gear 512 to rotate. The driving gear 512 drives the transmission bevel gear 513 to rotate through the synchronous belt 514. The transmission bevel gear 513 drives the screw bevel gear 510 to rotate, thereby rotating the driving screw 508 and finally moving the resistance rod 610.

[0061] One end of the resistance rod 610 penetrates into the non-Newtonian fluid chamber 609 and contacts the non-Newtonian fluid, and the other end is connected to the sealing plug 502 through the L-shaped connecting rod 611. When the resistance rod 610 moves slowly, the resistance rod 610 can move directly in the non-Newtonian fluid chamber 609 and drive the sealing plug 502 to move at the same time. Based on the characteristics of the non-Newtonian fluid itself, it encounters greater resistance when the moving speed is too fast. If the moving speed of the resistance rod 610 is too fast, the resistance rod 610 drives the non-Newtonian fluid chamber 609 to move together. While driving the sealing plug 502 to move, it also drives the push rod 608 and the shading plate 404 to move, so that the shading plate 404 moves to the upper side of the reflector 402 to expose the reflector 402.

[0062] During the operation of the capacitor of this embodiment, the core package 2 generates heat, which is transferred from the heat pipe 503 to the heat conductor 505, and the heat conductor 505 transfers the heat to the expansion gas in the expansion chamber 601. The volume of the expansion gas increases after being heated, which increases the air pressure in the expansion chamber 601, pushes the expansion piston 603 outward, and moves the expansion connecting rod 604. The expansion connecting rod 604 drives the L-shaped transmission rod 515 to move, and the L-shaped transmission rod 515 drives the driving rack 516 to move, and the driving rack 516 drives the driving gear 512 to rotate. The driving gear 512 drives the transmission bevel gear 513 to rotate through the synchronous belt 514, and the transmission bevel gear 513 drives the screw bevel gear 510 to rotate, thereby causing the driving screw 508 to rotate. When the driving screw 508 rotates, it can drive the screw nut seat 509 to translate, thereby driving the resistance rod 610 to move.

[0063] When the capacitor is in a normal working state, the temperature of the core package 2 is slowly increased, and the resistance rod 610 moves slowly. The resistance rod 610 can move directly in the non-Newtonian fluid chamber 609, and at the same time drive the sealing plug 502 to move. Since the driving screw 508 is a reciprocating screw, it can reciprocate, so the sealing plug 502 will also reciprocate to a certain extent, thereby drawing outside air into the heat conduction channel 501 or pushing the air in the heat conduction channel 501 to the outside, realizing the exchange of outside air and air in the heat conduction channel 501, and realizing heat exchange in the air exchange process, thereby reducing the temperature of the heat conduction channel 501, the heat conduction pipe 503 and the core package 2;

[0064] When the capacitor is short-circuited or damaged, the temperature of the core package 2 rises rapidly, and the resistance rod 610 moves quickly or slowly. The resistance rod 610 can drive the non-Newtonian fluid chamber 609 and the driving slide 607 to move while driving the sealing plug 502 to move, and then drive the push rod 608 and the shading plate 404, so that the shading plate 404 moves to the upper side of the reflector 402 to expose the reflector 402 to show that the capacitor is damaged. In this way, when the staff uses a flashlight to illuminate the circuit board, they can easily and accurately find the damaged capacitor.

[0065] In summary, in this embodiment, a reciprocating ventilation and heat conduction mechanism 5 and a temperature sensing mechanism 6 are provided. The temperature sensing mechanism 6 detects the temperature change of the core package 2 and controls the action of the reciprocating ventilation and heat conduction mechanism 5. The reciprocating ventilation and heat conduction mechanism 5 drives the sealing plug 502 to slide in the heat conduction channel 501, thereby attracting air into the heat conduction channel 501, or discharging the air in the heat conduction channel 501, to achieve heat exchange between the heat conduction channel 501 and the outside world, so as to reduce the temperature of the core package 2 and realize cooling of the capacitor.

[0066] At the same time, the present embodiment sets a hidden reflector mechanism 4, and the hidden reflector mechanism 4 and the reciprocating ventilation and heat conduction mechanism 5 are both connected to the temperature sensing mechanism 6. The temperature sensing mechanism 6 detects the temperature change of the core package 2, and controls the hidden reflector mechanism 4 and the reciprocating ventilation and heat conduction mechanism 5 to operate according to the temperature change rate. When the capacitor is short-circuited or damaged, the temperature of the core package 2 rises rapidly, and the reflector 402 in the hidden reflector mechanism 4 is exposed to show that the capacitor is damaged. In this way, when the staff uses a flashlight to illuminate the circuit board, they can easily and accurately find the damaged capacitor.

[0067] In this embodiment, a hidden reflector mechanism 4 and a temperature sensing mechanism 6 are provided. The temperature sensing mechanism 6 detects the temperature change of the core package 2. When the capacitor is short-circuited or damaged, the temperature of the core package 2 rises rapidly. The temperature sensing mechanism 6 drives the reflector 402 in the hidden reflector mechanism 4 to be exposed to show that the capacitor is damaged, thereby effectively solving the problem that damaged capacitors are difficult to find in the prior art and achieving simple and accurate finding of damaged capacitors.
