Abstract
The utility model discloses a wiring structure of annular earth wire. The wiring structure comprises an annular earth wire and a grounding bus, wherein the annular earth wire is connected with the grounding bus, and the annular earth wire and the grounding bus are located on a printed circuit board base plate. The wiring structure of annular earth wire disclosed by the utility model is used for reducing electromagnetic interference and improving the performance of a printed circuit board.
Description
Technical field
The utility model relates to a kind of wire structures, particularly relates to a kind of wire wiring structure circlewise.
Background technology
Electromagnetic interference (Electro-Magnetic Interference, EMI) be the electromagnet phenomenon that people find for a long time, it almost is found simultaneously with the phenomenon of galvanomagnetic effect, and British scientists in 1981 are delivered the article of " opinion is disturbed ", indicate the beginning of research interference problem.The interference problem in communication had been studied by Britain postal and telecommunication entities in 1989, made the research of interference problem begin to move towards through engineering approaches and industrialization.Electromagnetic interference is also a subject matter of printed circuit board (PCB), and in many countries, especially in Europe, the electromagnetic interference that may distribute any system has strict restriction.The conduction transmission must have complete circuit to connect between interference source and sensor, interference signal is delivered to sensor along this connecting circuit, interference phenomenon occurs, this transmission circuit can comprise wire, the conductive member of equipment, power supply, common impedance, ground connection flat board, resistance, inductance, electric capacity and mutual-inductance element etc., existing printed circuit board (PCB) exists electromagnetic interference, affects the performance of printed circuit board (PCB).
The utility model content
Technical problem to be solved in the utility model is to provide a kind of wire wiring structure circlewise, and it reduces electromagnetic interference, improves the performance of printed circuit board (PCB).
The utility model solves above-mentioned technical problem by following technical proposals: a kind of wire wiring structure circlewise, it is characterized in that, it comprises annular ground wire and earth bus, described annular ground wire is connected with described earth bus, and described annular ground wire, earth bus all are positioned on a printed circuit board base board.
Preferably, described annular ground wire is connected with a resistance, and described annular ground wire also is connected with an electric capacity.
Positive progressive effect of the present utility model is: the utility model wire wiring structure circlewise reduces electromagnetic interference, improves the performance of printed circuit board (PCB).
Description of drawings
Fig. 1 is the schematic diagram of a kind of wire wiring structure circlewise of the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, a kind of wire wiring structure circlewise of the utility model comprises annular ground wire 1 and earth bus 3, and annular ground wire 1 is connected with earth bus 3, and annular ground wire 1, earth bus 3 all are positioned on a printed circuit board base board 2.Annular ground wire 1 is exactly the ground wire that a ground wire forms ring-type, annular ground wire 1 can be connected with the 3rd resistance R 3, the 3rd resistance R 3 is connected successively with the 4th resistance R 4, the 5th resistance R 5, also be provided with the first resistance R 1 and second resistance R 2 of mutual series connection on printed circuit board base board 2, annular ground wire 1 can also be connected with a capacitor C, so just can the electromagnetic interference that the elements such as resistance, electric capacity produce be collected, by earth bus, electromagnetic interference is emitted, so just reduce electromagnetic interference, improve the performance of printed circuit board (PCB).
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
