Abstract
The utility model discloses a kind of electronic type static that can eliminate the consumer static radiation and eliminate circuit.The working method that it adopts is, utilization is that the static bypass circuit that core devices constitutes is eliminated static with R1, R2, C1, it is simple to the utlity model has circuit, the use electronic component is few, reliable in structure, long service life can effectively be eliminated characteristics such as static radiation, be mainly used on the electrical equipment such as computer, also can be used on other single-phase electric devices.
Description
Technical field
The utility model relates to a kind of static and eliminates circuit, and the especially a kind of static that can eliminate electrical equipment static radiation such as computer is eliminated circuit.
Background technology
Computer in use can produce static radiation, and particularly children and pregnant woman are very disadvantageous and static radiation is to human body.The method of eliminating the computer static radiation at present mainly contains two kinds, and promptly display adds the good earth of electrostatic screening net and computer power.The electrostatic screening net can influence the luminance brightness of display screen in use, simultaneously good ground connection must be arranged, otherwise not have shield effectiveness.Yet keyboard and host computer can not be used the electrostatic screening net, and their static radiation also is to exist.The good earth of computer power must depend on the good earth of external power source system, for various reasons, as: the external power source system does not have ground connection, or has used the power supply changeover device that does not have ground wire, or imperfect earth etc., computer in use can produce very strong static radiation like this.
Summary of the invention
The purpose of this utility model is that a kind of simple electronic type static of effectively eliminating static radiation of exploitation is eliminated circuit, settlement computer is not when having reliable power ground system, can produce very strong static radiation in the use, cause technical matters the injury of human body.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: electronic type static is eliminated circuit, it is characterized in that: by resistance R 1, R2, capacitor C 1 constitutes the static bypass circuit for core devices; Its annexation is after to be resistance R 2 in parallel with capacitor C 1, one termination power ground wire GND, the end of other end connecting resistance R1, another termination zero-power line N of resistance R 1.
The beneficial effects of the utility model are: it is simple to have a circuit, uses electronic component few, reliable in structure, and long service life can effectively be eliminated static radiation.
Description of drawings
Accompanying drawing 1 is a kind of circuit theory diagrams of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, after resistance R 2 and capacitor C 1 are in parallel, one termination power ground wire GND, the end of other end connecting resistance R1, another termination zero-power line N of resistance R 1 forms the static bypass circuit thus, by resistance R 2, capacitor C 1 constitutes the capacitance-resistance attenuator circuit.Wherein: R1 is 10-100k Ω, and R2 is 1-10M Ω, and C1 is 0.01-10 μ F.If the external power source system of electrical equipment such as computer does not have ground connection, then static discharges through zero line (N) by the static bypass circuit; If there is ground connection in the external power source system of electrical equipment such as computer, then the effect of static bypass circuit is to produce the static of a backup to discharge approach.During use, change the power lead of electrical equipment such as original computer into utilize the utility model to make power lead or product, or the product that series connection the utility model is made gets final product.
The utility model is mainly used on the electrical equipment such as computer, also can be used on other single-phase electric devices.
Claims (1)
