Abstract
The utility model relates to a single-phase voltage regulating power plug, which is assembled by a single-phase voltage regulating circuit whose output voltage can be continuously adjusted and a single-phase power plug. The voltage regulating circuit is composed of a bidirectional thyristor SCR, light emitting diodes LED[1] and LED[2], a potentiometer W with a switch K and a capacitor C. The knob of the potentiometer W and the two light emitting diodes are all exposed out of the opening of a power plug box, so users can conveniently adjust the voltage and observe the luminous display. The utility model can avoid often plugging and pulling of the power plug and can cancel the unsafe hidden danger, so the power utilization of load end is safe, and meanwhile, the utility model has convenient voltage adjustment and can reduce the manufacturing cost.
Description
The utility model relates to a kind of line connector in the essential electronic element class, is meant a kind of single-phase voltage-regulating attaching plug that is used for the single phase poaer supply power supply especially.
As everyone knows, the single-phase voltage-regulating circuit that output voltage can be regulated continuously, can be widely used in to carry out electric loading such as the various household electrical appliance of temperature adjustment, light modulation, speed governing, adjusting power and industrial electrical equipment instrument, they or be assemblied in one with controlled load, perhaps with controlled load partial installation, but all need to plug the single phase poaer supply plug when using, this just exists the electricity consumption hidden danger regularly.In addition, adopt the single-phase voltage-regulating circuit of these two kinds of mounting meanss, use and regulate inconvenience, and it is a lot of to make that generally production cost increases.
The purpose of this utility model is to provide a kind of single-phase voltage-regulating circuit and single phase poaer supply plug combination are increased less single-phase voltage-regulating attaching plug in safe in utilization, the easy to adjust and production cost of one.
Solution of the present utility model is as follows.It has the attaching plug that is made of attaching plug box and three copper grafting pole pieces (post), and its feature part is, is equipped with by bidirectional triode thyristor SCR, LED in the attaching plug box
1With LED
2, have a single-phase voltage regulating circuit that the potentiometer W of K switch and capacitor C constitute, wherein bidirectional triode thyristor SCR main pole with link to each other with the copper grafting pole piece (post) of the phase-connecting wire of attaching plug again after an end of capacitor C joins, another main pole of SCR and the end of potentiometer W join LED
1With LED
2Two ends make reverse parallel connection, one of them reverse parallel connection end extremely links to each other with the control of bidirectional triode thyristor SCR, and another reverse parallel connection end and the potentiometer W other end and K switch one end are connected to a bit altogether, the K switch other end links to each other with the capacitor C other end.
The utility model with foregoing circuit structure is when reality is made, and the circuit elements device can be assembled in the interior printed board of attaching plug box, LED
1With LED
2Can be exposed to outside the perforate of attaching plug box, show that the knob of potentiometer W exposes outside the perforate of attaching plug box, so that regulate so that observe it.The end that joins of the main pole of bidirectional triode thyristor SCR and potentiometer W in the utility model circuit, and the copper grafting pole piece (post) of the connecting to neutral line of attaching plug, respectively as two voltage output ends, behind the output line of connecting with the mains with link to each other with electric loading.Regulator potentiometer W can change the angle of flow that adopts the bidirectional triode thyristor SCR that rc phase-shift trigger circuit controls, and promptly continuously changes the input voltage of supplying with electric loading, to reach carry out the purpose of temperature adjustment, light modulation, speed governing and adjusting power with electric loading.
Obviously, the copper grafting pole piece (post) of outer phase-connecting wire of the present utility model is owing to link to each other with the main pole of bidirectional triode thyristor SCR and an end of capacitor C, therefore as will stop electric the time, only need the belt switch K of potentiometer W institute is turn-offed, then high potential that phase line is with is just blocked in attaching plug box of the present utility model inside by bidirectional triode thyristor SCR fully, and can not be sent power supply output line, more can not arrive and use electric loading inside, so just can exempt the regular plug of attaching plug, stop hidden danger, make that the load end Electrical Safety is reliable.Simultaneously, because regulating circuit and attaching plug are assembled into one, regulation voltage just can carry out on attaching plug easily, and needn't be near using electric loading; In addition, with the manufacturing cost that regulating circuit is installed in the attaching plug to be increased, generally install than split and than with attach together with electric loading low.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the stereoscopic-state schematic diagram of a kind of concrete structure of the utility model;
Fig. 2 is that Fig. 1 A of the present utility model is to view;
Fig. 3 is the B-B cutaway view of Fig. 2;
Fig. 4 is an electrical schematic diagram of the present utility model.
Referring to Fig. 1.The utlity model has the attaching plug that is made of attaching plug box 1 and three copper grafting pole pieces (post) 2,3,4, attaching plug box 1 is divided into cassette holder 11 and lid 12 two parts again, and available screw connects between them, also can adopt knock-down snapping.5,6 knob and the power supply output lines that are respectively potentiometer W.Attaching plug box 1 also can be made an integral body and use epoxy encapsulation.
Referring to Fig. 4.In attaching plug box 1, be equipped with by bidirectional triode thyristor SCR, LED
1With LED
2, have the single phase ac regulation circuit that the potentiometer W of K switch and capacitor C constitute, the annexation of components and parts is as described above in the circuit.Components and parts in this regulating circuit are assembled in the printed board 9 (referring to Fig. 3), LED wherein
1, LED
2The knob that reaches potentiometer W is revealed in outside the perforate of attaching plug box 1, and its Reference numeral is respectively 7,8,5 (simultaneously referring to Fig. 2). Reference numeral 2,3,4 in Fig. 4 circuit is the copper grafting pole piece (post) of distinguishing phase-connecting wire, connecting to neutral line and earth connection among Fig. 1 on the attaching plug box 1, and 6 of Reference numerals are the power supply output line among Fig. 1.
The utility model is specially adapted to the power supply as quartzy infrared warmer, and it is not only easy to adjust, reduces cost of manufacture, and during operation away from heater, consider from the Electrical Safety angle, uses more relieved reliably.
