Abstract

The utility model belongs to an electricity inserting connection technique, particularly a power receptacle which can be used for filtering high-frequency interference clutter in an electric network and avoiding the interference of the clutter generated by electronic equipment to the electric network. The utility model comprises a receptacle case body, and is characterized in that a high frequency power source filter is serially connected between corresponding jack reeds arranged in a power plug cord and a receptacle case, and the electromagnetic pollution can be effectively prevented.

Description

Supply socket with waveform purification function

The utility model belongs to electric connection technology, particularly a kind of supply socket that can the filtering electromagnetic noise interference.

The so-called multifunctional power socket that present almost huge numbers of families are all using, its structure be in a plurality of jacks live wire reed, ground wire reed, zero line reed respectively with the attaching plug line parallel, can insert a plurality of plugs simultaneously, what have also is equipped with power supply indicator, switch etc., is characterized in that a socket is transformed to a plurality of sockets.Along with modern social development, the electromagnetic pollution in space is on the rise, various household electrical appliance and information products are higher to the power supply wave shape quality requirement on the one hand, many on the other hand products but constantly send electromagnetic noise to electrical network and space, during the household electrical appliance switching on and shutting down of some charged sense even can produce by a relatively large margin disturbing pulse, the clean grade of the strong spike arteries and veins that also has thunder and lightning to produce in addition all can make many high frequency clutters that superposeed on the power supply sine wave, very easily damages various instruments and electric equipment products or influences operate as normal.

The purpose of this utility model provides a kind of supply socket with two-way purification ac power waveform.

The utility model comprises power cord plug and socket box body, it is characterized in that being connected in series power-supply filter between interior each the corresponding jack strip of power cord plug and box body.

Above-mentioned power-supply filter belongs to high frequency filter, can adopt R-C (resistance-capacitance) filter or L-C (inductor-capacitor) filter, for connected mode, can adopt Γ/T type connection, also can adopt ∏ type or balanced type connection.

The supply socket that the utility model provides, owing between the corresponding jack of power cord plug, be connected in series high frequency filter with each, various electromagnetic induction signals in the filtering civil power effectively, also can stronger inhibitory action be arranged to the spike disturbing pulse that thunder and lightning produces, the interference signal that can stop subscriber equipment to produce simultaneously again enters electrical network and causes electromagnetic pollution; Can protect various electronic equipments to avoid the influence of clutter effectively, prevent accidental damage, have positive environment protection significance again.

The utility model belongs to high-grade supply socket product, can be widely provides power conditioner for multiple household electrical appliance such as refrigerator, colour TV, computer, printer, facsimile machine and electronic equipment.

In the accompanying drawing, Fig. 1 is a structured flowchart of the present utility model, and Fig. 2, Fig. 3 represent two kinds of connections of L-C Γ mode filter respectively, and Fig. 4, Fig. 5 represent balanced type and two kinds of connections of ∏ type L-C respectively, and Fig. 6 represents an embodiment electrical connection graph of the present utility model.

Be further described below in conjunction with drawings and Examples.

Fig. 1 has represented clean-up effect, and civil power is input as the waveform of many burrs that superposeed on the sine wave, is output as purer sine wave behind power-supply filter.Fig. 2-Fig. 5 represents can be for selecting for use to adapt to the high frequency electric source filter circuit of different class requirements.

Commercially available multiple model power-supply filter also can be for selecting for use, that Fig. 6 adopted is commercially available aviation board DNF05-H type power-supply filter EMI, 1,2 ends are input, are connected with power cord plug, and wherein 1 end is a live wire, be serially connected with K switch, 3,4 ends are filter EMI output, and wherein 3 ends connect firewire jack, and 4 ends connect zero line jack, H is the reed in the jack, and E is an earth terminal.D, R1, C, DW, R2 are typical current rectifying and wave filtering circuit, the luminous second tube sheet LET work of power supply source indicator light.
