Description

Technical Field

[0001] The utility model belongs to the technical field of capacitors, and particularly relates to a surge-resistant capacitor for suppressing power supply electromagnetic interference. Background Art

[0002] With the rapid development of electronic information technology, the sales volume of various electronic products has been continuously increasing, driving the growth of the capacitor industry. Capacitors are common electronic components in electronic devices and are used in aspects such as DC blocking, coupling, bypass, filtering, tuning circuits, energy conversion, and control circuits. Considering the influence of factors such as environmental temperature and usage conditions during operation, overvoltage, overcurrent, or overheating of capacitors can cause partial breakdown of capacitor elements. The instantaneously generated heat causes the gas to expand, which can lead to the swelling or even explosion of the capacitor. When the capacitor explodes, it can cause relatively serious damage to the surrounding electronic components, resulting in the disconnection or burning of the entire circuit. Therefore, the ability of a capacitor to resist surge voltage is very important.

[0003] In the prior art, a surge-resistant capacitor cannot be effectively fixed when suppressing power supply electromagnetic interference, which easily leads to unstable anti-interference effects. Therefore, this application proposes a surge-resistant capacitor for suppressing power supply electromagnetic interference to solve the above problems. Summary of the Utility Model

[0006] The utility model is a surge-resistant capacitor for suppressing power supply electromagnetic interference, including a surge-resistant capacitor body. The surge-resistant capacitor body is arranged inside a limit block. A connecting plate is fixedly connected to the side of the limit block. A chute is opened on the connecting plate. A limit fixing device and an auxiliary clamping device are arranged on the connecting plate.

[0007] The limit fixing device includes a knob. A rotating rod is fixedly connected to the side of the knob. A gear is fixedly connected to the outside of the rotating rod.

A fixing plate is fixedly connected to the side of the sliding block away from the rack bar. A fixing rod is fixedly connected to the side of the fixing plate. A fixing block is fixedly connected to the side of the fixing rod away from the fixing plate.

[0008] Furthermore, the shape of the limit block is set to be annular, and the size of the limit block is adapted to the size of the surge-resistant capacitor body. The limit block can effectively limit the surge-resistant capacitor body.

[0009] Furthermore, the rotating rod is rotatably connected to a side of the anti-surge capacitor body away from the limiting block, the gear is meshed with the gear rod, and the rotating rod can drive the gear to mesh with the gear rod.

[0010] Furthermore, the sliding block is slidably connected to the inner side of the sliding groove, and the fixing plate is slidably connected to a side of the anti-surge capacitor body close to the limiting block, and the sliding block can slide in the sliding groove.

[0011] Furthermore, the auxiliary clamping device comprises a rotating shaft, the outside of the rotating shaft is fixedly connected with a connecting rod, and the side of the connecting rod is fixedly connected with a hook. The auxiliary clamping device can effectively resist the surge capacitor body for auxiliary clamping reinforcement.

[0012] Furthermore, the rotating shaft is rotatably connected to the side of the fixed block, the material of the rotating shaft is corrosion-resistant metal steel, and the rotating shaft can drive the connecting rod to rotate.

[0013] Furthermore, the shape of the connecting rod is set to be rectangular, the material of the connecting rod is metal steel, and the hook can be clamped to complete the auxiliary clamping reinforcement of the anti-surge capacitor body.

[0014] Furthermore, the shape of the hook is set to be trapezoidal, and the material of the hook is friction-resistant rubber.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model uses a limiting fixing device. After the anti-surge capacitor body is placed on the limiting block, the knob can be manually turned to drive the rotating rod to rotate. The rotating rod will drive the gear to engage with the gear rod, and the gear rod will drive the sliding block, the fixed plate, the fixed rod and the fixed block to move. After the fixed block moves to the fixed position, the anti-surge capacitor body can be effectively fixed, so that the anti-surge capacitor body can more effectively suppress the electromagnetic interference of the power supply, and the utility model is more practical.

[0017] 2. The utility model uses an auxiliary clamping device. After the fixing block completes the fixing of the anti-surge capacitor body, the connecting rod can be manually turned to rotate under the action of the rotating shaft. The connecting rod will drive the hook to move. When the two hooks are clamped together, the auxiliary clamping reinforcement of the anti-surge capacitor body can be effectively completed, further enhancing the practicality of the entire device.
