Description of drawings
Fig. 1 is the structural representation of the circuit structure of magnet controlled electric shock-prevention safety socket in the embodiment of the invention.
Embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
See also Fig. 1, this figure is the structural representation of the circuit structure of magnet controlled electric shock-prevention safety socket in the embodiment of the invention.
The circuit structure of the magnet controlled electric shock-prevention safety socket that the embodiment of the invention provides; Comprise magnetic 1, tongue tube 2, relay 3 and socket main body 4; One end of tongue tube 2 connects civil power live wire L; Coil one end of another relay termination 3 of tongue tube 2, another termination civil power zero line of the coil of relay 3 N; Two normally opened contacts one end of relay 3 meets the live wire L and the zero line N of civil power respectively, and two normally opened contact other ends of relay 3 are the socket contact sheet of combination hub main body 4 respectively; Magnetic 1 cooperates with tongue tube 2, the folding of magnetic 1 control tongue tube 2, and magnetic 1 is a Magnetic adhesive mat.
Tongue tube 2 is special keys of a kind of magnetosensitive; Usually by two or three reed contacts that soft magnetic material is made; Be encapsulated in the glass tube that is filled with inert gas (like nitrogen, helium etc.) or vacuum; The leaf end of parallel encapsulation is overlapping in the glass tube, and leaves certain interval or be in contact with one another often opening or normally-closed contact with the formation switch.When permanent magnet near tongue tube, the magnetic field that the coil electricity on the tongue tube forms makes the reed magnetization, so, the contact part of reed will be by magnetic attraction, when attraction during greater than the elastic force of spring, the contact will adhesive; When magnetic force was reduced to a certain degree, the contact was opened by the elastic force of spring.Tongue tube is simpler than common mechanical construction of switch, volume is little, speed is high, long working life; And compare with electronic switch, it has characteristics such as anti-load shock ability is strong again, and functional reliability is very high.
Relay 3 generally is made up of iron core, coil, armature, contact reed etc.As long as add certain voltage at the coil two ends; Will flow through certain electric current in the coil; Thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and fixed contact (normally opened contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the reaction force of spring, and moving contact and original fixed contact (normally-closed contact) are discharged.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.For " often open, normally closed " contact of relay, can distinguish like this: be in the fixed contact of off-state when relay coil is not switched on, be called " normally opened contact "; The fixed contact that is in on-state is called " normally-closed contact ".Relay generally has two strands of circuit, is low-voltage control circuit and high-pressure work circuit.
Socket main body 4 can be two hole socket or Three-hole socket, all is to realize the object of the invention, repeats no more at this.
The operation principle of the circuit structure of the magnet controlled electric shock-prevention safety socket that the embodiment of the invention provides is following:
The live wire L of one termination civil power of tongue tube 2; One end of the coil of another relay termination 3 of tongue tube 2, another termination civil power zero line N of the coil of relay 3 is when magnetic 1 during near tongue tube 2; Tongue tube 2 adhesive that is magnetized; The coil of relay 3 gets electric, the equal adhesive of two normally opened contacts of relay 3, and two normally opened contacts insert the live wire L and the zero line N of civil power respectively; When magnetic 1 left tongue tube 2, tongue tube 2 demagnetizations were broken off, the coil blackout of relay 3, and two normally opened contacts of relay 3 all break off, and two normally opened contacts cut off the civil power live wire L and the zero line N of original access respectively.Magnetic 1 is equivalent to the effect of " safety key ", and socket main body 4 is received the protection of magnetic 1.Socket main body 4 can not be switched on during nonmagnetic body 1, makes socket main body 4 be in a safe condition; When needing energising, plug magnetic 1 and get final product.
Need to prove that civil power live wire in the circuit structure of the magnet controlled electric shock-prevention safety socket that the embodiment of the invention provides and civil power zero line are substituted by DC power supply anode and DC power supply negative terminal, it also can be applied on the galvanic protection against electric shock circuit.
Compared with prior art, the circuit structure of magnet controlled electric shock-prevention safety socket provided by the invention adopts bipolarity to cut off electrocution-proof protection, and the magnetic control mode is simple and reliable, and coefficient of safety is high.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
