Abstract
The disclosed teflon-medium trimming capacitor comprises two ends with Teflon as medium. Thereby, this invention has little loss and well capacity on anti-impact and anti-vibration for bad environment, has voltage endurance up to 1500VDC, while capacity up to 2.6 times to the air-medium capacitor, and fit to wide application in different vacations.
Description
Technical field
The present invention relates to a kind of trimmer capacitor, especially trimming capacitor of PTFE medium.
Background technology
The trimmer capacitor that uses is an air dielectric at present, and this condenser capacity is little, and volume is big.
Summary of the invention
The object of the present invention is to provide and a kind ofly make the trimmer capacitor of medium with polytetrafluoroethylene, this trimmer capacitor has improved capacity and withstand voltage greatly, and volume is little.
Technical scheme of the present invention is: a kind of trimming capacitor of PTFE medium, and these trimmer capacitor two ends are provided with electric conductor, are provided with medium between the electric conductor, and medium is provided with a circle insulator outward, and the medium that is adopted between the electric conductor is a polytetrafluoroethylene.Polytetrafluoroethylene between this trimmer capacitor two ends electric conductor can be circular.At the inside and outside electrode slice that is provided with of the ring of circular polytetrafluoroethylene.Polytetrafluoroethylene between these trimmer capacitor both ends of the surface can be rectangular-shaped.On rectangular-shaped polytetrafluoroethylene, have electrode slice.The electric conductor of the electrode slice of this trimmer capacitor by being located at an end face is connected with conductive leading feet on being located at electric conductor, forms the stator pack of capacitor; Electrode slice is connected with the conductive leading feet that is located at this electric conductor by the electric conductor that is located at the other end, forms the mover group of capacitor; Stator pack is connected by the insulator between two electric conductors with the mover group, and connects together by the scolding tin wire bond, forms a capacitor.
The invention has the advantages that: polytetrafluoroethylene (PTFE) is an oxygen-containing polymers, and according to the characteristics of its electrical property, dielectric constant can reach 2.6 times of air, is applied on the trimmer capacitor to use as medium, improves capacity and withstand voltage greatly.Trimming capacitor of PTFE medium is developed according to the market demand, and it is little to have a loss, shock resistance, vibration ability height, can adapt to adverse circumstances, cost is low, and simple and convenient is installed, be widely used in communication and electronic instrument, Medical Instruments, aviation and military equipment are done line tuning and are used.Trimming capacitor of PTFE medium is compared with existing air dielectric trimmer capacitor, has withstand voltage height, can reach 1500VDC, and under the equal contact area situation, capacity is 2.6 times of air dielectric trimmer capacitor.Can manufacture that volume is little, capacity is big, be suitable for the modern electronic product development trend.
