Abstract
The utility model discloses an electric wire with an interference-free plug, comprising a plug (9), an electric wire (1), and a coil (3) wound by a conducting wire (10) passing through a set of magnetic rings in the plug (9), and the inductive reactance of the coil (3) increases with the increase of the frequency. The utility model has simple structure, and can effectively eliminate the electromagnetic interference of appliances, which is to prevent the inner interference of electrical appliances from coming into the alternating current power supply city network, effectively prevent the interference of the normal work of other electrical appliances, and enable the appliances to achieve the electromagnetic compatibility requirements.
Description
The utility model relates to power line, refers in particular to the power line of band plug.
Along with the raising of living standards of the people, the electric equipment products that enter family are more and more, become the necessity of Modern Family as large screen television, large power air-conditioned and various stereo sets etc.When enjoying comfortable that beautiful sensation that these audio-visual equipment bring and these household electrical appliances bring, the electromagnetic interference between these equipment becomes discordant note.Especially along with the increase of electric equipment products power, the interference problem that may cause is just more serious.And the electrical equipment that has itself is vulnerable to the influence of electromagnetic interference and performance is reduced when sending electromagnetic interference, and the electromagnetic interference of electric equipment products that Here it is and vulnerability to jamming problem are emc issue.The relevant expert spells out electromagnetic interference can cause very big harm to electrical network, even can cause serious accident to the destruction of communication and traffic.So solving electromagnetic interference problem is an a matter of great account, must improve the Electro Magnetic Compatibility level of household electrical appliances.
For example television set is in when work, and it can pollute electromagnetic environment when may be subjected to the electromagnetic interference of other electrical equipment, and has influence on the healthy of people.Household electrical appliance all are to enter AC power by power cord plug now, and the AC power conducted interference is a kind of main forms of electromagnetic interference.Suppressing the AC power conducted interference, is the jamproof important rings of household electrical appliances.
Task of the present utility model provides a kind of anti-interference power cord plug of being with, and it can stop the interference of electrical equipment inside to enter AC power city net effectively, prevents to disturb the operate as normal of other electrical equipment, promptly solves the conducted interference problem effectively.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind ofly be with anti-interference power cord plug, comprise plug and power line, at the coil of described plug inside conductor through one group of magnet ring coiling, its induction reactance of described coil increases along with increase frequency.
All need use the power line of band plug during household electrical appliances input power supply, but not see power line in the market with anti-interference plug.The utility model is simple in structure, only need to add that in plug the coil of a magnet ring coiling is an anti-interference filter, cost increases few but can eliminate the electromagnetic interference that household electrical appliances take place effectively and promptly stops the interference of electrical equipment inside to enter AC power city net, prevent to disturb the operate as normal of other electrical equipment effectively, make household electrical appliances can reach the requirement of Electro Magnetic Compatibility.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Accompanying drawing is the main pseudosection of present embodiment.
As shown in drawings, present embodiment comprises plug (9) and power line (1), plug (9) is by pedestal (8), pin (6), overcoat formations such as (4), and plug (9) inside conductor (10) is through the coil (3) of one group of magnet ring coiling, and its induction reactance of this coil (3) increases along with increase frequency; Lead (10) is connected with coil (3) by wiring card (2), and lead (10) is connected the back with pin (6) fixing with a compressing tablet (7); Pin (6) is last to have a section surface to apply with insulating barrier (5) from overcoat (4), to improve safety in utilization.
Claims (3)
1, a kind ofly be with anti-interference power cord plug, comprise plug (9) and power line (1), it is characterized in that: at the coil (3) of described plug (9) inside conductor (10) through one group of magnet ring coiling, its induction reactance of described coil (3) increases along with increase frequency.
2, a kind of anti-interference power cord plug of being with according to claim 1 is characterized in that: lead (10) is connected with coil (3) by wiring card (2), and lead (10) is connected the back with pin (6) fixing with a compressing tablet (7).
3, a kind of anti-interference power cord plug of being with according to claim 1 and 2 is characterized in that: pin (6) is last to have a section surface to apply with insulating barrier (5) from overcoat (4).
