A film capacitor

Abstract

The invention belongs to the technical field of electronic components, specifically a thin film capacitor, comprising a No. 1 electrode foil, a No. 2 electrode foil and a base body, the base body is cylindrical, and a No. 1 through groove is arranged in the base body. The No. 1 through-slot is a vortex line structure, and the No. 1 electrode foil is embedded in the No. 1 through-slot; the base body is also provided with a No. 2 through-slot, and the slot width of the No. 2 through-slot is equal to that of the No. 1 through-slot. Three times the width of the slot, the No. 2 slot is also a vortex structure, the No. 1 slot and the No. 2 slot are nested to form a double-swirl shape, and the base is made of polystyrene No. 2 electrode foil is arranged in the No. 2 through slot; the invention rotates the No. 2 electrode foil along the No. 2 slot, thereby reducing the overlapping area of ​​the No. 1 electrode foil and the No. 2 electrode foil projection, so that the staff The capacity of the film capacitor to store charge can be adjusted without disassembly, thereby improving the work efficiency of workers.

Description

technical field [0001] The invention belongs to the technical field of electronic components, in particular to a film capacitor. Background technique [0002] With the rapid development of electronic information technology, the upgrading speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products, continue to grow. Capacitor industry growth. Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. A capacitor, as the name suggests, is a "container for charging electricity", a device that holds charges. 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, etc. in circuits. In addition, any two conductors (including wires) that ar...

Problems solved by technology

[0004] This technical solution can absorb the heat generated by the capacitor during operation by filling the inside of the first cavity, the first radiating pipe, the second radiating pipe and the connecting pipe with cooling liquid, thereby avoiding the accumulation of heat. A radiating pipe, a second radiating pipe and connecting pipes can quickly dissipate the heat absorbed in the cooling liquid; but this technical solution still cannot solve the problem of reducing the capacity of the installed film capacitor on the existing circuit board. It is necessary to remove the original film capacitor and replace it with a film capacitor with a small capacity to achieve the goal, resulting in the limitation of this solution
