A kind of low-noise capacitor and its manufacturing method

Abstract

The invention discloses a low-noise capacitor and a manufacturing method thereof. It comprises a capacitor outer shell. A mounting groove is opened at the middle position of the top of the capacitor outer shell. The upper end of the inner wall of the mounting groove is engaged with a capacitor inner shell. There is a connecting groove in the middle of the inner wall of the connecting groove, a capacitor connector is fixed at the middle of the bottom of the inner wall of the connecting groove, a first vacuum groove is opened at the edge of the inner wall of the capacitor inner shell, and rubber protective strip. The invention relates to a low-noise capacitor and its manufacturing method. It is connected to an external plug-in structure through connecting wires on both sides of two metal butt rings, and a connection groove and a first vacuum are provided on the inner wall of the capacitor inner shell. The groove makes it difficult for the noise generated by the work to pass through the inner wall, reduces the noise transmission, makes the sound insulation effect better, and achieves a low-noise capacitor, thereby improving the practicability of the device.

Description

Technical field [0001] The present invention relates to the technical field of capacitors, and in particular, to a low noise capacitor and a manufacturing method thereof. Background technique [0002] The conventional capacitor is mainly a device device that acts as a circuit of the electrical equipment for coupling, and the capacitor plays an important role in the circuit of tuning, bypass, coupling, filtering and other circuits. The tuning circuit of the transistor radio is used to use it, color The coupling circuit of the TV, bypass circuit, etc. also use it. With the development of modern technology, the function of capacitors gradually increases, making it better to meet the needs of electrical appliances and circuit connections; [0003] In the prior art, when designing the low-noise capacitor, most designers pay attention to the installation strength of the design device, and the working elements inside the capacitor are stabilized by the reinforcing fixing structure of th...

AI Technical Summary

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.
