[0025] A novel high-performance long-life film capacitor includes a circuit board 1, a pin 4 is fixedly installed in the middle of the top of the circuit board 1, a capacitor body 2 is fixedly installed on the top of the pin 4, a clamping component 3 is arranged on the top of the circuit board 1, the clamping component 3 includes a clamping rod 301, the clamping rod 301 is slidably connected to both sides of the circuit board 1, a support rod 302 is slidably installed inside the clamping rod 301, a clamping frame 304 is fixedly installed in the middle of the support rod 302, a support column 305 is fixedly installed in the middle of the support column 304, and the support column 305 A sliding rod 308 is slidably installed in the middle interior, a connecting rod 309 is fixedly installed on both sides of the second end of the sliding rod 308, a rotating rubber frame 310 is rotatably installed on both sides of the connecting rod 309, a guide block 313 is fixedly installed on both sides of the top first end of the card frame 304, the rotating rubber frame 310 and the guide block 313 are slidably connected, and a fastening screw 303 is rotatably installed on the top of the card rod 301, a rubber extrusion plate 314 is slidably installed on both sides of the middle of the support column 305, and a card plate 315 is fixedly installed on both sides of the rubber extrusion plate 314.

[0026] In this embodiment, when fixation is required, the distance between the clamping rod 301 and the outside of the support rod 302 can be extended by adjusting the fastening screws 303, so as to facilitate clamping on the circuit board 1. By placing the pins 4 on both sides of the support column 305, the sliding rod 308 is pushed to slide in the middle of the support column 305. Pushing the sliding rod 308 will drive the rotating rubber frame 310 and the guide block 313 to contact through the connecting rod 309, so that the rotating rubber frame 310 can rotate toward the middle on both sides of the connecting rod 309. When the sliding rod 308 is pushed to slide in the middle of the support column 305, the rubber extrusion plate 314 will be squeezed. The rubber extrusion plate 314 drives the clamping plate 315 to slide to both sides, and cooperates with the rotating rubber frame 310 to fix the pins 4 therein, thereby reducing the probability of the pins 4 breaking due to shaking.

[0027] The card plate 315 is arranged between the pins 4, and the rotating rubber frame 310 is arranged on both sides of the pin 4. A clamping plate 311 is fixedly installed on the top of the rotating rubber frame 310, and a foam plate 312 is fixedly installed between the clamping plates 311. The foam plate 312 is arranged on both sides of the capacitor body 2. A rotating rod 306 is rotatably installed on the first side of the first end of the card frame 304, and the rotating rod 306 and the second side of the first end of the card frame 304 are internally slidably connected. A limiting pin 307 is arranged inside the second side of the first end of the card frame 304, and the limiting pin 307 and the second side of the rotating rod 306 are internally slidably connected.

[0028] In this embodiment, when fixation is required, the rotating rubber frame 310 will drive the clamping plate 311 and the foam plate 312 to clamp the capacitor body 2 in the middle when clamping. In this way, the capacitor body 2 can be clamped and fixed after the clamping pin 4 passes, avoiding vibration that causes the capacitor body 2 to break and be damaged, resulting in a reduction in lifespan.

[0029] Working principle: By adjusting the fastening screw 303, the distance between the clamping rod 301 and the outside of the support rod 302 can be extended to facilitate clamping on the circuit board 1. By placing the pins 4 on both sides of the support column 305, the sliding rod 308 is pushed to slide in the middle of the support column 305. Pushing the sliding rod 308 will drive the rotating rubber frame 310 to contact the guide block 313 through the connecting rod 309, so that the rotating rubber frame 310 rotates toward the middle on both sides of the connecting rod 309, and the sliding rod 308 is pushed to slide in the middle of the support column 305. When the rubber extrusion plate 314 moves, the rubber extrusion plate 314 drives the clamping plate 315 to slide to both sides, and cooperates with the rotating rubber frame 310 to fix the pin 4 therein, so as to reduce the probability of the pin 4 breaking due to shaking. When the rotating rubber frame 310 is clamped, it drives the clamping plate 311 and the foam plate 312 to clamp the capacitor body 2 in the middle, so that the capacitor body 2 can be clamped and fixed after the pin 4 is clamped, so as to avoid the capacitor body 2 breaking and damage caused by vibration, thereby reducing the service life.
