Description

一种电容器
技术领域
本实用新型涉及照明灯具领域,尤其为一种电容器。
背景技术
电容器通常简称其为电容,用字母C表示。定义1:电容器,顾名思义,是‘装电的容器’,是一种容纳电荷的器件。电容是电子设备中大量使用的电子元件之一,广泛应用于电路中的隔直通交,耦合,旁路,滤波,调谐回路, 能量转换,控制等方面。电容器,任何两个彼此绝缘且相隔很近的导体(包括导线)间都构成一个电容器。基于上述概念,我们可以开发出更多的适应更多不同场合需要的新型电容。
实用新型内容
实用新型目的:本实用新型针对现有技术的不足,提供了一种电容器。
本实用新型采用的技术方案为:一种电容器,包括内电极、外电极以及电机,所述外电极为圆筒状,所述内电极为圆柱体,所述内电极与所述电机连接且设置在所述外电极内,所述内电极与外电极同轴。
有益效果:本实用新型构思巧妙、机构合理,可以自动调节电容大小。
附图说明
图1为本实用新型提供的电容器的结构图。
具体实施方式:
以下结合说明书附图对本实用新型进行进一步说明:
如图1所示:一种电容器,包括内电极1、外电极2以及电机3,外电极2为圆筒状,内电极1为圆柱体,内电极1与电机3连接且设置在外电极2内,内电极1与外电极2同轴。转动电机3则内电极1随之转动,两个电极之间的对应面积发生变化,引起电容器的电容变化。

Claims (1)

1.一种电容器,其特征在于:包括内电极、外电极以及电机,所述外电极为圆筒状,所述内电极为圆柱体,所述内电极与所述电机连接且设置在所述外电极内,所述内电极与外电极同轴。
