Dual-modulation type plate-like capacitor

Abstract

The invention discloses a double-adjustable plate capacitor, which comprises a No. 1 body and a No. 2 body. The No. 1 body is a cylindrical cylinder with an open upper end. A lower capacitor plate is arranged in the No. 1 body, and the lower capacitor plate is supported by The column is connected and fixed with the No. 1 body. The No. 1 body is covered with the No. 2 body. The upper capacitor plate is installed under the No. 2 body. The upper capacitor plate is connected and fixed with the No. 2 body through the boom. The No. 2 body and the No. 1 body The bodies are connected by threads, and the inner wall of the upper end of the No. 1 body is clamped with a metal ring. The metal ring is in sliding contact with the upper capacitor plate. The electric connection pin is connected to the two input terminals of the rectifier through the conductive rod. The structure of the present invention is simple and reasonable, and the capacitor can be adjusted from two aspects, so as to achieve the effect of variable capacitance, which is convenient to use and helps to improve the performance of the capacitor body. service life.

Description

technical field [0001] The invention relates to a capacitor, in particular to a double-tuned plate capacitor. Background technique [0002] Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. Charges will move under force in the electric field. When there is a medium between the conductors, it will hinder the movement of the charges and cause the charges to accumulate on the conductors. However, the capacitors in the prior art are easily damaged when encountering unstable currents, and the existing The capacitance of the capacitor is fixed and cannot be adjusted in practice. In addition, the existing capacitor has an integrated design, which is inconvenient for later maintenance. Contents of the invention [0003] The object of the present invention is to provide a double-tuned plate capacitor to solve the problems raise...

Problems solved by technology

Charges will move under force in the electric field. When there is a medium between the conductors, it will hinder the movement of the charges and cause the charges to accumulate on the conductors. However, the capacitors in the prior art are easily damaged when encountering unstable currents, and the existing The capacitance of the capacitor is fixed and cannot be adjusted. In addition, the existing capacitor is designed in one piece, which is inconvenient for later maintenance.
