Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Electromagnetic relay is in automatic control circuit, play the execution unit controlled with buffer action, it is a kind of automatic switch that can control high pressure, big current with low-voltage, small area analysis, Fig. 1 is the schematic diagram of the structure and working principle of electromagnetic relay, 10 is electromagnet, 20 is armature, and 30 is springs, and 40 is moving contacts, 50 is stationary contacts, and stationary contact 50 has two; Electromagnetic relay operating circuit comprises low-voltage control circuit 100 and high-pressure work circuit 200: control circuit 100 is made up of electromagnet 10, armature 20, low-tension supply 80 and switch 60; Operating circuit 200 is by miniature bulb 70, power supply 90 and be equivalent to the stationary contact 50 of switch, moving contact 40 forms.
Wherein, electromagnet 10 is provided with two pins a, b, and the two ends of control circuit 100 are connected with two pins a, b of electromagnet 10 respectively.
Connect operating circuit 200, when normality, be not communicated with between moving contact 40 and stationary contact 50, operating circuit 200 disconnects.Certain voltage is added at electromagnet 10 two ends, certain electric current will be flow through in electromagnet 10, thus generation galvanomagnetic effect, armature 20 overcomes the iron core of pulling force suction to electromagnet 11 of return spring 30 under the effect of electromagnetic attracting force, thus the moving contact 40 of band moving armature 20 and stationary contact 50 (normally opened contact) adhesive.When after electromagnet 10 power-off, the suction of electromagnetism also disappears thereupon, and armature 20 returns to original position at the reacting force of spring 30, and moving contact 40 and original stationary contact 50 (normally closed contact) are discharged.Such adhesive, release, thus the object reaching conducting in circuit, cut-out.
Detailed process is: depressed by moving contact 40 with finger, then operating circuit is connected because moving contact 40 contacts with stationary contact 50 with stationary contact 50 by moving contact 40, and miniature bulb 70 is luminous.Closing Switch 60, armature 20 is inhaled by electromagnet 10, and moving contact 40 contacts with two stationary contacts 50 simultaneously, makes to be communicated with between moving contact 40 and stationary contact 50.At this moment spring 30 is elongated, and observes operating circuit 200 and is switched on, and miniature bulb 70 is luminous.Cut-off switch 60, electromagnet 10 loses magnetism, and has no attraction to armature 20.Armature 20 gets back to original position under the pulling force effect of spring 30, and separately, operating circuit 200 is cut off, and miniature bulb 70 is not luminous for moving contact 40 and stationary contact 50.
For " often open, normally closed " contact of relay, can distinguish like this: the stationary contact 50 being in off-state when the electromagnet 10 of relay is not energized, is called " normally opened contact "; The stationary contact 50 being in on-state is called " normally closed contact ".
All electromagnetic relay inner structures are substantially identical, existing connecting inner structural principle analysis and research: for 5V relay, two pin a of electromagnet 10, b provides 5V voltage, 5V electromagnet 10 resistance is about general 63 Europe, can obtain according to Ohm law I=U/R: 5V ÷ 63 Ω=79.4 milliampere, therefore relay needs output power to be: P=U*I=5V*79.4mA=397 milliwatt, because power required during relay contact analog control system is very little, so any 5V power supply bought on the market can meet testing requirement, general each electronics corporation can have conventional regulated power supply.
