Description

[0002] During the operation of electronic devices, capacitors, as a basic electronic component, are widely used in circuits for functions such as filtering, energy storage, and coupling.

[0003] Existing capacitors are used in special environments such as automotive electronic systems, industrial automation equipment, and aerospace instruments, where electronic devices are frequently subjected to vibration and shock. Capacitors are usually rigidly fixed and lack effective buffering and shock absorption structures. When subjected to external vibration, the connection points between the pins and the circuit board are prone to breakage due to stress concentration, leading to capacitor failure and affecting the stability and reliability of the entire circuit. For example, during vehicle operation, engine vibration and road bumps can cause continuous vibration to automotive electronic devices, which may cause poor contact or damage to ordinary capacitors. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses an anti-vibration capacitor, comprising a base 1, a capacitor 2 disposed in the center of the top surface of the base 1, and L-shaped grooves symmetrically formed on both sides of the bottom surface of the base 1, connecting the capacitor 2. Leads 3 are disposed within the L-shaped grooves. Two arc-shaped blocks 4, fixed to the base 1, are symmetrically disposed on both sides of the capacitor 2. Arc-shaped grooves are formed on the top surface of the arc-shaped blocks 4. The base 1 and arc-shaped blocks 4 are made of polycarbonate (PC), which has high strength and good insulation, forming a stable mounting structure with the capacitor 2. The L-shaped grooves and copper alloy leads 3 facilitate a stable connection between the leads 3 and the circuit board. The good toughness and conductivity of the copper alloy can distribute the force on the leads 3, improving connection reliability and thus enabling a stable connection between the capacitor 2 and the circuit. The arc-shaped blocks 4 provide a mounting foundation for the subsequent anti-vibration structure, initially enhancing the stability of the capacitor 2 installation. Soft rubber blocks 5 are attached to both sides of the inner wall of the arc-shaped grooves, and arc-shaped clamps 6 are glued between the soft rubber blocks 5. The cross-section of the arc-shaped clamps 6 is inverted. The L-shaped, arc-shaped clamp 6 has one end of its top surface abutting against the outer wall of the capacitor 2. The soft silicone rubber block 5 has excellent elasticity and aging resistance. Combined with the arc-shaped clamp 6 made of reinforced nylon, it can effectively buffer the impact force during vibration, making it easy to flexibly wrap and fix the capacitor 2. The high elasticity of silicone rubber can absorb vibration energy, and the high strength of reinforced nylon ensures the stability of the clamp structure, improving the stability of the capacitor 2 in a vibration environment, thereby achieving the anti-vibration protection function of the capacitor 2. The pins 3 extend out of the outer walls of both sides of the base 1 through the L-shaped groove. Compared with direct extension, the L-shaped groove can share the stress on the pins 3 when subjected to external pulling or vibration. The copper alloy pins 3 themselves have a certain toughness. The combination of the two helps to reduce the risk of breakage of the connection point between the pins 3 and the circuit board due to stress concentration, improves the vibration resistance of the pins 3 connection, and thus achieves the function of ensuring the electrical connection stability of the capacitor 2.

[0020] In this invention, an insulating tape 7 is provided in the middle of the bottom surface of the base 1. The insulating tape 7 is rectangular. The insulating tape 7 is made of polyimide and has extremely high insulation resistance and good high temperature resistance. Its placement in the middle of the bottom surface of the base 1 facilitates the isolation of any electrical connection that may exist between the base 1 and the mounting surface, preventing leakage. The excellent insulation properties and stability of polyimide improve the safety of the capacitor 2, thereby achieving reliable insulation protection for the capacitor 2 and the circuit. Multiple mounting holes are equidistantly opened on the periphery of the bottom surface of the base 1. Sponge pillars 8 are provided in the mounting holes. Adhesive layers 9 are fixed to both ends of the sponge pillars 8. The top of the sponge pillar 8 is glued to the top surface of the mounting hole through the adhesive layer 9. A damping block 10 is glued to the bottom of the sponge pillar 8 through the adhesive layer 9. The bottom part of the damping block 10 extends out of the bottom surface of the base 1. The sponge pillar 8, made of high-elasticity polyurethane sponge, has good flexibility. The nitrile rubber damping block 10, made of nitrile rubber, is pushed against the PCB board during installation due to its expansion properties. The high resilience of the polyurethane foam provides continuous thrust, and the excellent damping performance of the nitrile rubber effectively dissipates vibration energy. The combination of these two materials significantly reduces the transmission of vibration to the capacitor 2, improving the overall shock resistance of the capacitor 2 and thus enabling efficient shock absorption. Multiple anti-slip rubber pads 11 are evenly distributed between the mounting holes on the bottom surface of the base 1. The anti-slip rubber pads 11 are disc-shaped. Made of natural rubber, the anti-slip rubber pads 11 have a large coefficient of friction and are evenly distributed on the bottom surface of the base 1, which increases the friction between the base 1 and the mounting surface, preventing the capacitor 2 from shifting or sliding on the mounting surface. The good anti-slip performance and wear resistance of natural rubber improve the stability of the capacitor 2 installation, thus ensuring the capacitor 2 is securely installed.

[0021] Working principle: In the use of this utility model, the base 1 is first glued to the PCB board with insulating tape 7 to isolate the electrical connection to prevent leakage and provide initial fixation; the pin 3 extends through the L-shaped groove and is soldered to the PCB board pad to achieve electrical connection, and the L-shaped groove reduces the risk of pin 3 breakage; the anti-slip rubber pad 11 prevents the base 1 from sliding with high friction and enhances installation stability; the arc-shaped clamp 6 cooperates with the soft rubber block 5, the soft rubber block 5 buffers and absorbs shock, and the arc-shaped clamp 6 abuts against the outer wall of the capacitor 2 to complete the limiting fixation; during installation, the sponge column 8 in the mounting hole on the bottom surface of the base 1 is squeezed and generates flexible expansion, pushing the damping block 10 to tightly abut against the PCB board. When there is external vibration, the sponge column 8 continues to apply force to ensure that the damping block 10 is in contact with the PCB board. The two absorb and consume vibration energy respectively, reduce vibration transmission, and ensure that the capacitor 2 works stably in the vibration environment; at this point, the device is used.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
