Low-noise capacitor and manufacturing method thereof

Abstract

The invention discloses a low-noise capacitor and a manufacturing method thereof. The low-noise capacitor comprises a capacitor outer shell, wherein a mounting groove is formed in the middle of the top end of the capacitor outer shell, a capacitor inner shell is clamped to the upper end of the inner wall of the mounting groove, a connecting groove is formed in the middle of the inner wall of the capacitor inner shell, a capacitor connector is fixedly arranged in the middle of the bottom of the inner wall of the connecting groove, a first vacuum groove is formed in the edge of the inner wall of the capacitor inner shell, and rubber protection strips are fixedly arranged in the middles of the two sides of the inner wall of the connecting groove. According to the low noise capacitor and the manufacturing method thereof, the low noise capacitor is connected with the external plug-in structure through the connecting wires on the two sides of the two metal butt-joint rings, and the connecting groove and the first vacuum groove are formed in the inner wall of the inner shell of the capacitor, so that noise generated during working is not prone to penetrating through the inner wall to be transmitted out, noise transmission is reduced, the sound insulation effect is better, and the low-noise capacitor is achieved so as to improve the practicability of the device.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a low-noise capacitor and a manufacturing method thereof. Background technique [0002] Traditional capacitors are mainly used for coupling and shunting of electrical equipment circuits, and capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. It is used in the tuning circuit of transistor radios. Color It is also used in the coupling circuit and bypass circuit of the TV. With the development of modern technology, the function of the capacitor is gradually increased, so that it can better meet the needs of electrical appliances and circuit connections; [0003] In the prior art, when designing and manufacturing this low-noise capacitor, most designers will pay attention to the installation strength of the design device, and the working elements inside the capacitor will be stably clamped through layer-by-layer reinforcement and fixing...

Problems solved by technology

[0003] In the prior art, when designing and manufacturing this low-noise capacitor, most designers will pay attention to the installation strength of the design device, and the working elements inside the capacitor will be stably clamped through layer-by-layer reinforcement and fixing structures, so that it is not easy to work. It produces higher noise, but the internal components of the capacitor are more complicated when used. If more clamping structures are used, it will affect the internal working state of the device, thereby reducing the practicability of the capacitor.
