[0025] See also Figure 1-6 The utility model of the anti-seismic capacitor comprises a capacitor 1 and a circuit board 2. The capacitor 1 is plugged into the circuit board 2 through pins. A clamping device is provided on the outer surface of the circuit board 2. A buffer component is provided between the clamping device and the circuit board 2. The clamping device is used to fix the capacitor 1. The buffer component supports the capacitor 1 through the clamping device. When in use, the capacitor 1 is inserted into the jack of the circuit board 2 through the pins and is fixed by soldering on the back, so that the capacitor 1 is fixed to the circuit board 2. When the electrical product is in use, the product is easily affected by external force and vibration. Among the components on the internal circuit board 2, the capacitor 1 is large in size and heavy in mass, and is most affected, which makes it easy for the pins of the capacitor 1 to be affected by force. The weld is open, so that the capacitor 1 falls off the circuit board 2, reducing the service life of the product. In order to solve the problems in the prior art, the present application is provided with a clamping device, which can be clamped on the outside of the capacitor 1, and then a buffer component is arranged between the clamping device and the circuit board 2, so that the capacitor 1 obtains good support from the circuit board 2 through the clamping device and the buffer component. During use, when the capacitor 1 is vibrated, the impact of the vibration will be transmitted to the buffer component through the clamping device, and the buffer component is compressed by cooperating with the circuit board 2, so that the impact of the vibration is buffered, and then the vibration of the capacitor 1 is buffered, thereby effectively reducing the vibration of the pins of the capacitor 1, and thus increasing the service life of the capacitor 1.

[0026] In this utility model, please refer to Figure 1 , 2, 3, 4, 5, the clamping device includes a fixing ring 3 sleeved on the outside of the capacitor 1, a plurality of push rods 4 are radially penetrated on the fixing ring 3, the push rods 4 are threadedly connected with the fixing ring 3, the fixing ring 3 is sleeved on the outer surface of the capacitor 1, and can move up and down. In order to fix the position of the fixing ring 3 relative to the capacitor 1, the push rods 4 are rotated to make the push rods 4 move relative to the fixing ring 3 toward the center of the circle, so that the push rods 4 are pressed against the outer surface of the capacitor 1, so that the fixing ring 3 is fixed relative to the capacitor 1, and then the fixing ring 3 is fixed to the capacitor 1 through the push rods 4.

[0027] In order to facilitate the fixing of the capacitor 1 by the top rod 4, in this embodiment, please refer to Figure 1 , 3 5. A notch groove is deepened radially at a position corresponding to the inner wall of the fixing ring 3 and the push rod 4. The push rod 4 penetrates the side wall of the notch groove from the outside of the fixing ring 3 to the inside and is threadedly connected with the side wall. By rotating the push rod 4, the push rod 4 can be moved outward or inward relative to the fixing ring 3, thereby tightening or loosening the capacitor 1.

[0028] In order to increase the contact area between the top rod 4 and the capacitor 1 and prevent the top rod 4 from damaging the outer surface of the capacitor 1, in this embodiment, refer to Figure 1 , 3 , 5. An arc-shaped tightening plate 5 is provided at the inner end of the push rod 4. The inner wall of each arc-shaped tightening plate 5 is in conflict with the outer side of the capacitor 1. When the fixing ring 3 needs to tighten the capacitor 1, the push rod 4 is rotated to drive the arc-shaped tightening plate 5 close to the capacitor 1, and the arc-shaped tightening plate 5 tightens the capacitor 1. The inner wall of the arc-shaped tightening plate 5 cooperates with the outer surface of the capacitor 1, so that the capacitor 1 is easily fixed.

[0029] In order to reduce the impact of the capacitor 1 being subjected to vibration, in the present utility model, please refer to Figure 1 , 2 , 5, 6, the buffer assembly includes a support portion hinged to the fixing ring 3, the interior of the support portion is provided with a pressing portion, and the internal space of the support portion above the pressing portion is provided with a spring 9. After the capacitor 1 is installed on the circuit board 2, the fixing ring 3 is first fixed to the side of the capacitor 1, and then extended outward from the interior of the supporting portion through the pressing portion to press against the circuit board 2. When the capacitor 1 is vibrated, the generated vibration impact will be transmitted to the pressing portion through the fixing ring 3 and the supporting portion, so that the pressing portion shrinks inside the supporting portion and compresses the spring 9. The vibration impact is buffered by the deformation of the spring 9, and then the vibration impact of the capacitor 1 is buffered, so that the pins of the capacitor 1 and the soldering points of the circuit board 2 are buffered, thereby avoiding the desoldering of the solder at the pins and increasing the service life of the capacitor 1.

[0030] In order to make the length of the support portion adjustable, thereby achieving the preload force of the volume spring 9, in this embodiment, please refer to Figure 1 , 2 , 3, 5, 6, the supporting part includes a movable block 6 hinged to the fixing ring 3, a threaded rod 8 is arranged at the bottom end of the movable block 6, a sleeve 7 is threadedly connected to the outer surface of the threaded rod 8, the interior of the sleeve 7 is sleeved with the abutting part, and the spring 9 is located between the abutting part and the threaded rod 8. By rotating the sleeve 7, the threaded rod 8 can be made to enter or be withdrawn from the sleeve 7, thereby changing the degree to which the threaded rod 8 compresses the spring 9, and the preload force of the spring 9 can be adjusted according to usage.

[0031] See also Figure 5 , 6 The pressing part includes a slide plate 10 that slides up and down inside the sleeve 7. The spring 9 is located between the slide plate 10 and the threaded rod 8. A pressing rod 11 is coaxially arranged on the bottom surface of the slide plate 10. The pressing rod 11 extends to the bottom of the sleeve 7 and penetrates the sleeve 7. A track plate 12 is hinged at the bottom end of the pressing rod 11. When the capacitor 1 is subjected to rotation and transmitted to the sleeve 7, the sleeve 7 will be extended and retracted relative to the pressing rod 11, so that the slide plate 10 slides inside the sleeve 7. The sliding of the slide plate 10 compresses the spring 9, so that the vibration is buffered.

[0032] See also Figure 2 , 4 , the pins of capacitor 1 pass through the jacks of circuit board 2 and are soldered on the back side of circuit board 2.

[0033] When using the utility model: first, insert the pin of the capacitor 1 into the inner wall jack of the circuit board 2, and fix it by soldering on the back of the circuit board 2, then put the fixing ring 3 on the outside of the capacitor 1, and then drive the arc-shaped clamping plate 5 to press against the capacitor 1 through the top rod 4, so that the fixing ring 3 is fixed on the capacitor 1, and then rotate the sleeve 7 and the clamping rod 11 to make the movable block 6 rotate, so that the clamping rod 11 drives the track plate 12 to move closer to the capacitor 1, until the track plate 12 can press against the upper surface of the circuit board 2 and compress the spring 9 to a certain extent, at this time, the capacitor 1 and the buffer assembly are installed, when in use, when the capacitor 1 is vibrated, the vibration is transmitted to the sleeve 7, so that the sleeve 7 produces a contraction displacement relative to the clamping rod 11, and the clamping rod 11 drives the slide plate 10 to compress the spring 9, and through the deformation of the spring 9, the vibration impact is buffered, and then the pin of the capacitor 1 is buffered by the vibration, avoiding the problem of open welding of the pin of the capacitor 1 due to vibration.
