Embodiment Construction

[0021] The present invention will be described in further detail below by means of specific embodiments:

[0022] The reference signs in the drawings of the description include: shell 1, bottom plate 2, top plate 3, first metal plate 4, second metal plate 5, capacitance 6, first sliding shaft 7, second sliding shaft 8, conductive contact block 9. Inductor 10, resistor 11, insulating layer 12.

[0023] Such as figure 1 As shown, a capacitor includes a rectangular shell 1 made of aluminum metal, the left end plate of the shell 1 is welded to the first metal plate 4 in the shell 1 as the negative terminal of the entire capacitor, and the right end plate of the shell 1 is used as the negative end of the capacitor. The positive terminal is welded to the second metal plate 5 inside the casing 1 . Both the first metal plate 4 and the second metal plate 5 are welded on the bottom plate 2 . A capacitor 6 made of a conductive wire spiral is welded on the bottom plate 2 , and the left...

Abstract

The invention relates to an adjustable capacitor, and particularly discloses a capacitor. The capacitor comprises a bottom plate and a top plate obliquely arranged on the bottom plate; two ends of the bottom plate are vertically connected with a first metal plate and a second metal plate with different heights; the top plate and the bottom plate are connected via the first metal plate and the second metal plate; a spiral electric capacity is arranged on the bottom plate; the electric capacity is connected with the first metal plate; the lower surface of the top plate is provided with a first sliding shaft and a second sliding shaft in mutual parallel; the first sliding shaft and the second sliding shaft are provided with a conductive contact block; both the first sliding shaft and the second sliding shaft are in sliding connection with the conductive contact block; the conductive contact block is contacted with the electric capacity; the conductive contact block is electrically connected with the second metal plate and an inductor is connected between the conductive contact block and the second metal plate; the second sliding shaft and the second metal plate are connected; and the first sliding shaft passes through the top plate and is connected with a resistor via a wire. The capacity changes automatically along with changes of load current and frequency.

Description

technical field [0001] The invention relates to a capacitor, in particular to an adjustable capacitor. Background technique [0002] There are two types of existing capacitors: polarized capacitors and non-polarized capacitors. Polarized capacitors are mainly used in power supply circuits and filter circuits, and their uses are relatively fixed, and the number of uses is limited. Nonpolar capacitors have good electromagnetic compatibility, reliability and safety, and are used in a large amount in the modern era of miniaturization and high intelligence requirements of electronic products, so their application prospects are very broad. For different modern intelligent electronic products, we need to use capacitors of different models and specifications. When using them, we must pay attention to many parameter requirements, and their versatility is poor. At the same time, a large number of capacitors with mismatched parameters also cause a waste of resources. [0003] At pres...
