Detailed Implementation

[0024] 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.

[0025] Example: Please refer to Figure 1-4A film capacitor with vibration resistance includes a capacitor body 1. A positioning disk 6 is fixedly connected to the bottom end of the capacitor body 1. The center line of the positioning disk 6 is on the same vertical plane as the center line of the capacitor body 1. A connecting seat 7 is fixedly connected to the bottom end of the capacitor body 1. A positive electrode pin 8 is fixedly connected to one side of the bottom of the connecting seat 7, and a negative electrode pin 9 is fixedly connected to the other side of the bottom of the connecting seat 7. Support sleeves 10 are fixedly connected to both sides of the bottom of the connecting seat 7. The bottom end of the positioning disk 6 is provided with a vibration-resistant structure to reduce vibration.

[0026] The vibration-resistant structure includes a mounting plate 5. The bottom end of the positioning plate 6 is movably connected to the mounting plate 5. The bottom end of the mounting plate 5 is provided with a through groove 11. The top end of the mounting plate 5 is fixedly connected to a positioning ring 13. The inside of the positioning ring 13 is fixedly connected to a rubber ring 15. The top end of the mounting plate 5 is fixedly connected to a vibration isolation pad 12.

[0027] The through groove 11 is movably connected to the connecting seat 7, and the vibration isolation pad 12 is movably connected to the positioning plate 6;

[0028] The rubber ring 15 is movably connected to the positioning disk 6, and the center line of the positioning ring 13 and the center line of the positioning disk 6 are on the same vertical plane;

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, after the capacitor is installed, the positioning plate 6 at the bottom of the capacitor body 1 will be attached to the top of the vibration isolation pad 12. The vibration isolation pad 12 is attached between the positioning plate 6 and the mounting plate 5, which can effectively reduce the impact of vibration on the positioning plate 6 and the capacitor body 1 after the mounting plate 5 is subjected to vibration, thereby reducing the vibration amplitude of the capacitor body 1. At the same time, the rubber ring 15 inside the positioning ring 13 is attached to the outside of the positioning plate 6, which can further reduce vibration, so as to prevent the capacitor as a whole from vibrating for a long time, causing a decrease in stability or a secure connection with the circuit, thus achieving effective vibration resistance.

[0030] Positioning sleeves 14 are fixedly connected to both sides of the top of the positioning disk 6, positioning posts 18 are fixedly connected to both sides of the top of the mounting plate 5, spring pieces 17 are fixedly connected to both sides of the top of the positioning posts 18, and positioning blocks 16 are fixedly connected to the top of the spring pieces 17.

[0031] The positioning post 18 is movably connected to the positioning sleeve 14, and the positioning block 16 is movably connected to the positioning sleeve 14;

[0032] The spring pieces 17 on both sides of the top of the positioning post 18 are arranged symmetrically, and the center line of the positioning post 18 and the center line of the positioning sleeve 14 are on the same vertical plane.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when installing the capacitor, the connector 7 at the bottom of the capacitor body 1 is inserted into the through slot 11. At the same time, the positioning post 18 at the top of the mounting plate 5 is inserted into the positioning sleeve 14, and the positioning post 18 pushes the spring piece 17 through the positioning sleeve 14. Finally, the spring piece 17 pushes out the positioning block 16 and makes the positioning block 16 fit against the top of the positioning sleeve 14, thereby positioning the positioning plate 6 through the positioning sleeve 14. The positioning post 18 fitting against the inside of the positioning sleeve 14 can effectively support the capacitor body, realizing quick assembly and disassembly of the capacitor.

[0034] The capacitor body 1 is movably connected to the outer shell 2, the outer shell 2 is fixedly connected to the outer shell 3, and the outer shell 2 is fixedly connected to the outer shell 3 with a reinforcing rib 4.

[0035] The supporting rib 3 is fixedly connected to the positioning plate 6, and the reinforcing rib 4 is fixedly connected to the supporting rib 3;

[0036] Specifically, such as Figure 1 and Figure 3 As shown, a set of outer shells 2 are installed outside the capacitor body 1 of the capacitor. The outer shells 2 protect the capacitor body 1. At the same time, support ribs 3 and reinforcing ribs 4 are installed on the outside of the outer shells 2 by welding. The cross arrangement of support ribs 3 and reinforcing ribs 4 can effectively support the outer shells 2, improve the strength of the outer shells 2, and prevent the capacitor from deforming when it is hit. The connection between the support ribs 3 and the positioning plate 6 can improve the stability of the capacitor and reduce the damage rate of the capacitor.

[0037] Working Principle: When using this invention, during capacitor installation, the connecting seat 7 at the bottom of the capacitor body 1 is inserted into the through slot 11. Simultaneously, the positioning post 18 at the top of the mounting plate 5 is inserted into the positioning sleeve 14, and the positioning post 18 pushes the spring piece 17 through the positioning sleeve 14. Finally, the spring piece 17 pushes out the positioning block 16, causing it to adhere to the top of the positioning sleeve 14. Thus, the positioning sleeve 14 positions the positioning plate 6. The positioning post 18, adhering to the inside of the positioning sleeve 14, effectively supports the capacitor body. After installation, the positioning plate 6 at the bottom of the capacitor body 1 adheres to the top of the vibration damping pad 12. The vibration damping pad 12, adhering between the positioning plate 6 and the mounting plate 5, effectively reduces vibration received by the mounting plate 5. The positioning ring 13 has a negative impact on the positioning disk 6 and the capacitor body 1, thereby reducing the vibration amplitude of the capacitor body 1. At the same time, the rubber ring 15 inside the positioning ring 13 is attached to the outside of the positioning disk 6 to further reduce vibration, so as to prevent the capacitor as a whole from vibrating for a long time, which would cause a decrease in stability or a loss of connection with the circuit. A set of outer shell 2 is installed on the outside of the capacitor body 1. The outer shell 2 protects the capacitor body 1. At the same time, the outer shell 2 is also equipped with support ribs 3 and reinforcing ribs 4 by welding. The cross arrangement of support ribs 3 and reinforcing ribs 4 can effectively support the outer shell 2, improve the strength of the outer shell 2, and prevent the capacitor from deforming when it is hit. The connection between the support ribs 3 and the positioning disk 6 can improve the stability of the capacitor.
