Abstract
A power supply cord with anti-electromagnetic-disturbance function relates to the improvement of an electric equipment part. The structure is that the anti-electromagnetic-disturbance part is directly integrated with the power supply cord. The utility model has the advantages that many original types of equipment are not equipped with an anti-electromagnetic-part, and if alternation is made now, the wire harness in machine body even a shell die has to be changed. The problems can be completely solved through the utility model, which is easy in use.
Description
The utility model belongs to electronic technology field, relates to a kind of improvement of electric equipment parts.
Power line is indispensable parts on the various electrical equipment, and filter (anti-electromagnetic interference device) also is the device that a lot of electrical equipment must be installed, usually above-mentioned two kinds of devices are two parts independently on the electric equipment, at present, anti-electromagnetic interference device is not installed having on some electric equipments, these electric equipments in the course of the work will be to producing electromagnetic interference around it like this, influence the normal operation of other electric equipment, cause electromagnetic pollution.
The purpose of this utility model provides a kind of electromagnetic interference resistance power line that filter and power line is combined as a whole and becomes parts.
The technical solution of the utility model is as follows:
To resist electromagnetic interference device and power line directly to make one.
The utility model has the advantages that:
Anti-electromagnetic interference device is not installed in original a lot of electric equipments, as reequiping now, then need be changed wire harness in the body, even will change outer casing mold, by realization of the present invention, the problems referred to above just can be solved fully, use very convenient.
Fig. 1 is filter circuit figure of the present utility model;
Fig. 2 is triangle capacitor filter figure of the present utility model;
Fig. 3 is capacitor filter figure of the present utility model;
Below in conjunction with accompanying drawing the utility model is described further:
Wherein: La, Lb are that inductance, R are that resistance, C are electric capacity;
All going here and there on two power lines among Fig. 1 has inductance L a, Lb, and is parallel with capacitor C 2, the C3 of resistance R and capacitor C 1 and series connection, the tie point ground connection of capacitor C 2, C3 between two power lines.
Between two power lines, be parallel with capacitor C 2, the C3 of capacitor C 1 and series connection among Fig. 2, the tie point ground connection of capacitor C 2, C3.
Between two power lines, be parallel with capacitor C 1 among Fig. 3.
Above-mentioned anti-electromagnetic interference device all can be arranged in the attaching plug, also can with the discrete setting of attaching plug.
