Abstract
The utility model discloses an AC power socket with an interference suppression inductance, which is composed of a toroidal magnetic core, windings, a plug inserting sheet, a socket reed, a casing, etc. A pair of symmetrical toroidal magnetic core windings is arranged in a power socket, the plug inserting sheet is connected with the starting end of each of the windings, and the socket reed is connected with the tail end of each of the windings. The plug inserting sheet is connected with an AC network, and the socket reed is connected with an electric power line plug of an electric appliance. A symmetrical winding of the windings causes the windings to have a better inhibition effect on a common mode signal which enters the windings through the starting end or the tail end.
Description
The utility model relates to a kind of with disturbing the ac power plug seat that suppresses inductance.Specifically, in general office space and home environment were used, the utility model can provide extra electromagnetic interference rejection for when using AC power to provide the AC power connection as the electrical equipment of the energy.
Development of electronic technology has promoted the development of electronic apparatus, brings great convenience for people's work, life.Increasing of the kind of using along with electrical equipment in office space and the home environment, kind, the electromagnetic wave in work and living space becomes increasingly complex.Especially at office space and home environment, multiple electrical equipment is by same ac power supply, AC power cord provides path for electromagnetic interference signal, cause electrical equipment to be subjected to the interference of the electromagnetic interference introduced by the power supply supply access, and the situation that spreads by the power supply supply access of the electromagnetic interference that produces of electrical equipment.
The Electro Magnetic Compatibility of electrical equipment more and more is subjected to the attention of national governments, the numerous and confused corresponding standard of formulating, the electromagnetic interference limit value of regulation electrical equipment, and the limit value of the anti-electromagnetic interference of electrical equipment, wherein just comprise the requirement of electrical equipment to the electromagnetic interference and the anti-electromagnetic interference of AC power path, Here it is electrical equipment is to the Electro Magnetic Compatibility of AC power.
Electrical equipment manufacturer is for satisfying this requirement, need measure at the multiple electromagnetic compatibility of electrical equipment internal implementation, some electrical equipment has also used a kind of special power line, is equipped with in its power-line plug to disturb to suppress inductance, to reach the Electro Magnetic Compatibility requirement of this electrical equipment to AC power.Because various electrical equipment are because of the restriction of structure space, the factors such as restriction of cost price, and the difference of environment, its Electro Magnetic Compatibility to AC power is not entirely satisfactory, also have many electrical equipment just not possess Electro Magnetic Compatibility during fabrication in addition to AC power, therefore, solution electrical equipment is the problem that user and electrical equipment manufacturer need solve to the Electro Magnetic Compatibility of AC power.
The purpose of this utility model provides a kind of with disturbing the ac power plug seat that suppresses inductance, and in its incoming transport power supply, the power line of electrical equipment links to each other with this connector assembly.This connector assembly to the electromagnetic interference of electrical equipment through its power line transmission, reaches the electromagnetic interference that exists in the AC power and blocks isolation, thereby can improve the Electro Magnetic Compatibility of electrical equipment to AC power when providing the power supply energy path for electrical equipment.
Band described in the utility model disturbs the ac power plug seat that suppresses inductance, comprise: magnet ring, winding, plug slice, Die for Reeds of Connector Jack and shell etc., its realization is the magnet ring winding that a pair of symmetry is housed in source jack-socket, the top plug inserted sheet of winding, terminal combination hub reed.Plug slice is connected with AC network, and Die for Reeds of Connector Jack is connected with appliances power source line plug.
Band described in the utility model is disturbed the power supply base of the plug slice incoming transport power supply of the ac power plug seat that suppresses inductance, make AC power enter the magnet ring winding of this connector assembly, receive on the Die for Reeds of Connector Jack of this connector assembly through the plug slice of this connector assembly; When appliances power source line plug inserts this connector assembly, through this connector assembly incoming transport power supply.The magnet ring winding of this connector assembly is a pair of winding that is wound with symmetry on a high frequency magnet ring, constitutes high frequency common mode with magnet ring and suppresses inductance.Because the symmetrical coiling of winding, make it to no matter being that top or the terminal common-mode signal that enters winding from winding all has good inhibitory effect.Because conducted in the AC power, or electrical equipment is mainly the common mode form through the electromagnetic interference that self power line conducted, therefore, this connector assembly can be obtained and suppress interference effect preferably.
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 assembles schematic diagram for the utility model embodiment.
Referring to Fig. 1.Magnet ring (1) is the high frequency magnet ring, and the magnet ring specification that present embodiment is selected is 26 * 16 * 5, and its initial permeability is about 250.In the electromagnetic compatibility practice, the inductance value of magnet ring winding is generally 0.3～24mH.Two groups of coils of the winding (2) on magnet ring (1) select for use line directly to be the enamelled wire of Φ 1.5, respectively form around 12 circles symmetrically on magnet ring, and its inductance value is about 17mH, is fit to the operating position of most of electrical equipment.Two winding tops of magnet ring winding (2) link to each other with plug slice (3), this connector assembly can be inserted in any reference power supply socket, two windings of magnet ring winding (2) are terminal to link to each other with Die for Reeds of Connector Jack (4), can make any reference power supply line plug insert this connector assembly to obtain the connection of AC power.Last lower casing (5) is magnet ring (1), winding (2), plug slice (3), Die for Reeds of Connector Jack cappings such as (4), prevents from that each electrification device from exposing to cause dangerously, and bolt (6) will be gone up lower casing (5) and carry out fasteningly, make this connector assembly become as a whole.
Because the utility model will disturb the inhibition inductance to be contained in the connector assembly, can be according to electrical equipment requirements dissimilar, different rated power, and the electromagnetic interference situation in the different frequency scope, select corresponding magnet ring, around last suitable coil, satisfying the electromagnetic compatibility requirement of different electrical equipment, and it is convenient to change remodeling, make that the scope of application of this connector assembly is bigger, avoided existing electrical equipment adapted band to disturb and suppressed the limitation that power line " is once decided lifelong ".
Connector assembly of the present utility model is not limited to the form of present embodiment, can be made into various dissimilar, as porous socket or row seat etc.
Claims (2)
1, a kind of with disturbing the ac power plug seat that suppresses inductance, comprise plug slice, Die for Reeds of Connector Jack, shell, it is characterized in that in source jack-socket, being equipped with the magnet ring winding of a pair of symmetry, the top plug inserted sheet of winding, terminal combination hub reed, plug slice is connected with AC network, and Die for Reeds of Connector Jack is connected with appliances power source line plug.
2, according to claim 1 a kind of with the ac power plug seat that disturbs the inhibition inductance, it is characterized in that the magnet ring winding of connector assembly, be a pair of winding that on a high frequency magnet ring, is wound with symmetry, constitute high frequency common mode with magnet ring and suppress inductance.
