Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a capacitor with a protective pin structure. Background Technology

[0002] A capacitor, often simply referred to as capacitance for its ability to store charge, is represented by the letter C. A capacitor consists of two electrodes and a dielectric material between them. The dielectric material is an electrical dielectric. When placed in an electric field between two parallel plates carrying equal and opposite charges, polarization charges are generated on the surface of the dielectric due to polarization. This causes a corresponding increase in the charge bound to the plates, maintaining a constant potential difference between the plates. This is why a capacitor has the characteristic of capacitance.

[0003] Chinese Patent Publication No. CN215770883U discloses a capacitor with a protective pin structure, including a capacitor body. A terminal pin is fixedly mounted on the top of the capacitor body, a first connecting plate is fixedly mounted on the left side of the capacitor body, and a second connecting plate is fixedly mounted on the left side of the capacitor body and behind the first connecting plate. This invention utilizes a rotating disk on a connecting rod, which is fixed to the first and second connecting plates. This rotation of the disk and the connecting rod causes the protective shell to rotate, protecting the capacitor body. A sealing ring contacts the capacitor body, ensuring complete protection. Furthermore, a pin protection cover protects the terminal pin, thus achieving the effect of protecting the capacitor pin and preventing damage to the capacitor pins when the capacitor is not in use, which could lead to the capacitor malfunctioning.

[0004] However, in actual use, the above device adjusts the position of the fixed plate by sliding the sliding block on the fixed plate in the groove, but does not fix the slider. Therefore, the fixed plate will still shift after the position is adjusted, which will cause the fixed capacitor to shift as well. Therefore, the above device has a major defect.

[0032] Please see Figure 1-10 This utility model provides a technical solution: a capacitor with a protective pin structure, including a capacitor shell 1, a plurality of wiring pins 2 on the top of the capacitor shell 1, a protective shell 3 on the top of the capacitor shell 1, a sealing ring 5 fixedly connected to the bottom of the protective shell 3, and a plurality of pin protection cylinders 4 fixedly inserted into the top of the protective shell 3.

[0033] The protective shell 3 has fixing mechanisms on both its left and right sides. Each fixing mechanism includes a limiting plate 7 with an L-shaped cross-section. The inner side of the limiting plate 7 is respectively attached to the side walls of the capacitor shell 1 and the protective shell 3. A limiting hole 8 is formed at the top of the limiting plate 7, and a fixing block 6 is movably inserted into the inner cavity of the limiting hole 8. The fixing block 6 is fixedly connected to the top of the protective shell 3. A horizontal plate 9 is fixedly connected to the side of the limiting plate 7 away from the protective shell 3. A connecting rod 10 is movably threaded through the horizontal plate 9, and a spring 11 is movably sleeved on the outer edge of the connecting rod 10. A baffle 12 is fixedly connected to the top of the rod 10. The connecting rod 10 is movably connected to the side wall of the capacitor housing 1. A spring 11 is fixedly connected to the top of the horizontal plate 9. The top of the spring 11 is fixedly connected to the baffle 12. A first connecting plate 13 is fixedly connected to the bottom of the connecting rod 10. A second connecting plate 14 is provided on both the front and rear sides of the first connecting plate 13. A pin 15 is rotatably connected to the inner cavity of the first connecting plate 13. The two ends of the pin 15 are fixedly connected through the adjacent second connecting plates 14. The second connecting plates 14 are fixedly connected to the side wall of the capacitor housing 1.

[0034] Limiting rods 16 and several toothed blocks 17 are fixedly connected to both the front and rear sides of the capacitor housing 1. A movable frame 18 is movably fitted on the limiting rod 16. A mounting plate 19 is fixedly connected to the side of the movable frame 18 away from the capacitor housing 1. A ring 21 is provided on the top of the mounting plate 19. A plug-in plate 22 is fixedly connected to the outside of the ring 21. The plug-in plate 22 is movably inserted between two toothed blocks 17. A screw 20 is provided on the top of the ring 21. Several toothed blocks 17 are arranged linearly from left to right. Several toothed blocks 17 are located on the top of the limiting rod 16. The cross-section of the limiting rod 16 is U-shaped. A through hole 23 is provided on the mounting plate 19. The bottom end of the screw 20 movably passes through the ring 21 and the through hole 23.

[0035] Working Principle: This utility model discloses a capacitor with a protective pin structure. During use, the protective shell 3 is moved to the top of the capacitor shell 1, and then the protective shell 3 is moved downwards. The protective shell 3 causes the pin protection cylinder 4 to be sleeved on the outside of the wiring pin 2. Then, the limiting plate 7 is flipped upwards, rotating around the pin shaft 15. At the same time, the limiting plate 7 is pulled upwards, causing the horizontal plate 9 to move on the outer edge of the connecting rod 10. Simultaneously, the spring 11 is compressed, and the limiting plate 7 moves upwards to the top of the fixing block 6. Then, the pulling force on the limiting plate 7 is slowly released. Under the elastic action of spring 11, the limiting plate 7 moves downward and is sleeved on the outside of the fixing block 6. The limiting plate 7 and the fixing block 6 cooperate with each other to press and fix the protective shell 3. At this time, the protective shell 3 contacts the capacitor shell 1 through the sealing ring 5, so that the protective shell 3 completely protects the capacitor shell 1. The pin protection cylinder 4 protects the wiring pin 2, thereby achieving the effect of protecting the capacitor pin. This avoids the capacitor pin from being damaged when the capacitor is not in use, which would cause the capacitor to be unable to be used normally, and improves the safety of the capacitor when it is not in use.

[0036] During capacitor installation, since each electronic component has a different size and a different fixing position, the mounting plate 19 can be moved. The mounting plate 19 drives the movable frame 18 to move on the outer edge of the limiting rod 16, thereby adjusting the position of the mounting plate 19. Then, the ring 21 is moved, and the ring 21 drives the plug plate 22 to be inserted between two adjacent toothed blocks 17. Then, the screw 20 is passed through the ring 21 and the through hole 23 to fix the capacitor shell 1 to the electrical components. At the same time, the screw 20 fixes the ring 21 and the plug plate 22. The plug plate 22 and the toothed blocks 17 cooperate to limit the mounting plate 19, preventing the mounting plate 19 from shifting, thereby preventing the capacitor from shifting after installation. This improves stability and allows it to be fixed with electronic components of different sizes, preventing the mounting plate 19 from being fixed and inconvenient to fix with other electronic components.

[0037] By adjusting the position of the mounting plate 19 and then using the screws 20 and the through holes 23, the capacitor housing 1 is fixed to the electrical components, thus enabling it to be fixed with electronic components of different sizes. This prevents the fixed plate on the capacitor from being fixed and inconvenient to fix with other electronic components.
