Problems solved by technology

[0002] Capacitors are mainly used to eliminate the crosstalk of various high-frequency signals generated by the chip itself to other chips, or installed in the power circuit to perform the functions of bypass, decoupling, filtering and energy storage. Capacitors are used by elevators to run up and down An electronic component commonly used in the elevator, the elevator will vibrate when it is running up and down, and it will resonate with the capacitor. During this period, the capacitor will continue to resonate and cause the capacitor to fall off, causing the decoupling and filtering functions of the capacitor to weaken. Effect of short circuit

Abstract

The invention discloses a patch-type anti-vibration capacitor which comprises a mounting mouth, a plate frame and a coiled strip, wherein the mounting mouth is arranged on the center of the plate frame; more than two rounds of coiled strip are disposed on the plate frame; the coiled strip is composed of a PCB strip and more than two capacitor bodies; the capacitor bodies are arranged in a straight line on the PCB strip; the PCB strip is gradually wound around the plate frame; and each capacitor body is provided with a capacitor, a top column, a support frame, an elastic strip and a placing disc. The influence of resonance on the capacitor is mainly reduced by the top column and the elastic strip. The connection relationship between the capacitor and the support frame is enhanced by the top column. The capacitor ensures that a mounting base does not horizontally shift, is completely prevented from detachment, and cannot cause a short circuit. A mesh-like planar structure formed by a triangular stabilizer can easily dissipate the heat generated during the operation of the capacitor, thereby improving the heat resistance.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a patch type anti-vibration capacitor. Background technique [0002] Capacitors are mainly used to eliminate the crosstalk of various high-frequency signals generated by the chip itself to other chips, or installed in the power circuit to perform the functions of bypass, decoupling, filtering and energy storage. Capacitors are used by elevators to run up and down An electronic component commonly used in the elevator, the elevator will vibrate when it is running up and down, and it will resonate with the capacitor. During this period, the capacitor will continue to resonate and cause the capacitor to fall off, causing the decoupling and filtering functions of the capacitor to weaken. The effect of a short circuit. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solutions: a chip-type anti...
