Description

Technical Field

[0001] This utility model relates to the field of capacitors, and in particular to a high-voltage resistant surface-mount aluminum electrolytic capacitor. Background Technology

[0002] Traditional surface-mount aluminum electrolytic capacitors are typically installed by soldering their leads directly to a printed circuit board (PCB). While this connection method is robust, it requires desoldering and resoldering when the capacitor needs replacement due to aging, overheating, or breakdown. This repair process is not only cumbersome and inefficient, but the repeated thermal cycling can also easily damage the PCB.

[0003] To address the aforementioned issues, this patent proposes a high-voltage surface-mount aluminum electrolytic capacitor that can be easily and quickly replaced, avoiding repeated soldering of the PCB board, thus solving the above technical problems. Utility Model Content

[0004] The main purpose of this invention is to propose a high-voltage resistant surface-mount aluminum electrolytic capacitor, which aims to solve the problem that traditional surface-mount aluminum electrolytic capacitors, with their leads directly soldered onto the printed circuit board, are prone to damaging the printed circuit board when damaged and replaced.

[0005] To address the aforementioned problems, this utility model proposes a high-voltage resistant surface-mount aluminum electrolytic capacitor, comprising a capacitor body with two symmetrically connected pins at its lower end. A connecting base is provided at the lower end of the capacitor body, and two symmetrically connected solder pins penetrate the lower end of the connecting base. An electrical connection assembly is provided between the pins of the capacitor body and the connecting base, allowing the pins to be electrically connected to the solder pins via the electrical connection assembly, and enabling detachment from the connecting base via the electrical connection assembly. A heat dissipation assembly is provided on the exterior of the capacitor body and is fixed to the connecting base via the heat dissipation assembly.

[0006] Preferably, the electrical connection assembly includes a connecting tube and a fixed electrical connection clamp, and two connecting slots are symmetrically opened on the outer side of the upper end of the connecting base, and the outer ends of the two connecting slots are connected to clamping grooves.

[0007] Preferably, the outer end of the clamping slide is connected to an adjustment slide on the upper end of the connecting base, the connecting slot is provided with a connecting tube, and the outer end of the connecting tube is connected to a fixed electric connecting plate located at the bottom of the inner cavity of the clamping slide.

[0008] Preferably, the upper outer side of the fixed electrical connector is symmetrically connected with support springs, and the upper ends of the two support springs are connected to a movable electrical connector located on the upper side of the inner cavity of the clamping groove. The upper end of the movable electrical connector is slidably connected to a push plate located on the upper side of the inner cavity of the clamping groove.

[0009] Preferably, both the movable electrical clamp and the push plate are wedge-shaped, and the outer end of the push plate extends through the inside of the adjustment groove and is connected to an adjustment slide block, which is slidably connected inside the adjustment groove.

[0010] Preferably, the upper end of the adjusting slide is connected to a limiting clamp block located at the upper end of the connecting base, and the inner end of the limiting clamp block is provided with a limiting slot, and a limiting strip connected to the lower side of the outer wall of the capacitor body is engaged inside the limiting slot.

[0011] Preferably, the heat dissipation component includes heat dissipation elastic fins, and multiple heat dissipation elastic fins that are attached to the outside of the capacitor body are connected to the upper outer side of the connecting base, and arc-shaped heat dissipation limiting fins are connected to the upper ends of the multiple heat dissipation elastic fins.

[0012] Preferably, the plurality of heat dissipation limiting fins are all snapped onto the outer side of the upper end of the capacitor body, and a disassembly pressure ring passes through the interior of the plurality of heat dissipation limiting fins, and the disassembly pressure ring is slidably connected inside the plurality of heat dissipation limiting fins.

[0013] Beneficial effects: 1. The capacitor of this utility model includes a detachable capacitor body and a connecting base, which allows the capacitor body to be quickly electrically connected to two soldering pins at the lower end of the connecting base through an electrical connection component. This means that when the capacitor body needs to be replaced, it does not need to be directly soldered to the PCB. It can be quickly replaced simply by plugging and unplugging the capacitor body to the connecting base, avoiding damage to the PCB board caused by repeated soldering, reducing maintenance costs, and improving replacement efficiency.

[0014] 2. The electrical connection assembly of this utility model uses the downward pressing and pushing of the capacitor body and the pushing cooperation between the wedge-shaped pushing plate and the movable electrical connection clamping plate to allow the movable electrical connection clamping plate to clamp and fix the pins with the fixed electrical connection clamping plate, so that the capacitor body and the soldering pins can be stably electrically connected and the pins can be fixed.

[0015] 3. This utility model provides heat dissipation elastic fins and arc-shaped heat dissipation limiting fins on the connecting base, allowing the capacitor to be inserted between the heat dissipation elastic fins and heat dissipation limiting fins while being installed on the connecting base. The heat dissipation elastic fins and heat dissipation limiting fins provide heat dissipation and limit the capacitor, ensuring stable operation of the capacitor and secure installation of the capacitor.

[0016] 4. This utility model sets a disassembly ring inside the arc-shaped heat dissipation limiting fins, and separates the heat dissipation limiting fins from the upper end of the capacitor body by pressing down the disassembly ring, thereby releasing the limitation on the capacitor body and allowing the capacitor body to be pulled out smoothly, thus realizing the rapid disassembly of the capacitor body and improving the replacement efficiency of the capacitor body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a high-voltage surface-mount aluminum electrolytic capacitor, including a capacitor body 1. Two pins are symmetrically connected to the lower end of the capacitor body 1. A connecting base 2 is provided at the lower end of the capacitor body 1, and two soldering pins 3 symmetrically penetrate the lower end of the connecting base 2. An electrical connection assembly is provided between the pins of the capacitor body 1 and the connecting base 2, and the pins can be electrically connected to the soldering pins 3 through the electrical connection assembly, and can be detached from the connecting base 2 through the electrical connection assembly. A heat dissipation assembly is provided on the outside of the capacitor body 1, and is fixed to the connecting base 2 through the heat dissipation assembly. During the soldering process of the high-voltage surface-mount aluminum electrolytic capacitor to the PCB board, the high-voltage surface-mount aluminum... The electrolytic capacitor includes a capacitor body 1 and a connecting base 2. The capacitor body 1 can be installed and removed from the connecting base 2 via an electrical connection assembly and a heat dissipation assembly. The capacitor body 1 can be electrically connected to two solder pins 3 via the electrical connection assembly and soldered to the PCB board via the two solder pins 3. At the same time, the capacitor body 1 can be externally cooled and limited by the heat dissipation assembly, so that the capacitor body 1 can be soldered to the PCB board via the connecting base 2 and the solder pins 3. The capacitor body 1 can be quickly installed and removed from the connecting base 2 by plugging and unplugging, thereby avoiding repeated soldering to the PCB board when the capacitor body 1 is damaged and replaced, preventing damage to the PCB board, reducing maintenance costs, and improving replacement efficiency.

[0022] Preferably, the electrical connection assembly includes a connecting tube 7 and a fixed electrical connection clamp 8. Two connecting slots 4 are symmetrically opened on the outer side of the upper end of the connecting base 2, and the outer ends of both connecting slots 4 are connected to clamping grooves 5. The outer ends of the clamping grooves 5 are connected to adjusting grooves 6 opened on the upper end of the connecting base 2. A connecting tube 7 is disposed inside the connecting slot 4, and the outer end of the connecting tube 7 is connected to a fixed electrical connection clamp 8 located at the bottom of the inner cavity of the clamping groove 5. Supporting springs 9 are symmetrically connected to the outer side of the upper end of the fixed electrical connection clamp 8, and the upper ends of the two supporting springs 9 are connected to movable electrical connection clamps 10 located on the upper side of the inner cavity of the clamping groove 5. A pushing plate 11 located on the upper side of the inner cavity of the clamping groove 5 is slidably connected to the upper end of the movable electrical connection clamp 10. Both the movable electrical connection clamp 10 and the pushing plate 11 are wedge-shaped, and the outer end of the pushing plate 11 penetrates through the interior of the adjusting groove 6 and is connected to an adjusting slide 12. The adjusting slide 12 is slidably connected to... Inside the adjustment slide 6, the upper end of the adjustment slide 12 is connected to a limiting clamp 13 located on the upper end of the connecting base 2, and the inner end of the limiting clamp 13 is provided with a limiting slot 14. The limiting slot 14 is engaged with a limiting strip 15 connected to the lower side of the outer wall of the capacitor body 1. During the process of installing the capacitor body 1 on the upper end of the connecting base 2, the two pins at the lower end of the capacitor body 1 are respectively inserted into the two connecting tubes 7, and guided by the connecting tubes 7 into the fixed electrical connection plate 8, thereby making an electrical connection with the welding pin 3. When the lower end of the capacitor body 1 contacts the upper end of the two limiting clamps 13, since the upper end of the limiting clamps 13 is set with an arc surface, the lower end of the capacitor body 1 will push the limiting clamps 13 outward and slide into the two limiting clamps 13, allowing the limiting clamps 13 to slide outward on the upper end of the connecting base 2, and driving the adjustment slide 12 to slide outward inside the adjustment slide 6.

[0023] At this time, the adjusting slide 12 drives the wedge-shaped pushing plate 11 to slide from the inside of the clamping slide 5 into the adjusting slide 6, and presses it downward through the inclined lower end face of the inclined upper end face of the movable electrical connector 10, so that the wedge-shaped movable electrical connector 10 slides downward inside the clamping slide 5 and fits tightly against the upper end of the pin inserted into the fixed electrical connector 8, so that the fixed electrical connector 8 and the movable electrical connector 10 firmly clamp the pin, thereby fixing the pin and making the pin fit tightly against the fixed electrical connector 8, ensuring the stable connection between the pin and the fixed electrical connector 8, and ensuring the stable connection between the pin and the welding pin 3 through the fixed electrical connector 8.

[0024] Furthermore, when the capacitor 1 slides between the two limiting clamps 13 and comes into contact with the connecting base 2, the limiting strip 15 on the outer wall of the capacitor 1 can just fit into the limiting slot 14 opened at the inner end of the limiting clamp 13, thereby limiting the capacitor 1 between the two limiting clamps 13 and the upper end of the connecting base 2, preventing the capacitor 1 from accidentally detaching from the connecting base 2, and ensuring a stable connection between the pin and the soldering pin 3 and the fixed electrical connection clamp 8.

[0025] Preferably, the heat dissipation assembly includes heat dissipation elastic fins 16. Multiple heat dissipation elastic fins 16 are connected to the outer side of the upper end of the connecting base 2 and adhere to the outside of the capacitor body 1. Each of the multiple heat dissipation elastic fins 16 has an arc-shaped heat dissipation limiting fin 17 connected to its upper end. The multiple heat dissipation limiting fins 17 are snapped onto the outer side of the upper end of the capacitor body 1. A disassembly pressure ring 18 passes through the interior of each of the multiple heat dissipation limiting fins 17 and is slidably connected inside the multiple heat dissipation limiting fins 17. During the installation of the capacitor body 1 into the heat dissipation assembly, because the heat dissipation limiting fins 17 are arc-shaped, the lower end of the capacitor body 1 can pass through the upper end of the heat dissipation limiting fins 17. The inner arc-shaped surface smoothly slides between multiple heat dissipation limiting fins 17 and between multiple heat dissipation elastic fins 16. When the capacitor body 1 is attached to the connecting base 2, the upper end of the capacitor body 1 just slides to the lower end of the multiple heat dissipation limiting fins 17. Under the elastic action of the heat dissipation elastic fins 16, the multiple heat dissipation limiting fins 17 are snapped onto the outside of the upper end of the capacitor body 1, thereby limiting the upper end of the capacitor body 1. At the same time, the multiple heat dissipation elastic fins 16 are tightly attached to the outside of the capacitor body 1, so that the capacitor body 1 can be fixed by the multiple heat dissipation limiting fins 17 and dissipate heat through the multiple heat dissipation elastic fins 16 and the multiple heat dissipation limiting fins 17.

[0026] Furthermore, during the disassembly of capacitor 1, because the heat dissipation limiting fins 17 are arc-shaped and the disassembly ring 18 is slidably connected inside the multiple heat dissipation limiting fins 17, when the disassembly ring 18 is pressed down, it can push the multiple heat dissipation limiting fins 17 outward through the arc-shaped inner wall of the heat dissipation limiting fins 17, causing the multiple heat dissipation limiting fins 17 to move outward and separate from the upper end of capacitor 1. Then, by pulling capacitor 1 upward, capacitor 1 can be smoothly pulled out from between the multiple heat dissipation limiting fins 17. At the same time, the limiting clips on the outer wall of capacitor 1... Strip 15 can be ejected from the limiting slot 14 under the action of tension. At this time, the inner end of the limiting clamp 13 is no longer pushed by the capacitor body 1, and the pushing plate 11 is no longer pulled by the adjusting slide 12 and the limiting clamp 13. It can slide inward inside the clamping slide 5, so that the movable electrical connection clamp 10 slides upward under the action of the supporting springs 9 on both sides of the lower end, and releases the clamping and fixing of the plug. At the same time, the pushing plate 11 is pushed inward, so that the plug can be smoothly pulled out from the connecting tube 7 and the fixed electrical connection clamp 8, thereby separating the capacitor body 1 from the connecting base 2.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
