Description
Technical field
The utility model relates to contactor field, is specifically related to a kind of contactor.
Background technology
Contactor refers to cut-offfing of the overload current frequently closing, carry and cut-off normal current and regulation in the narrow sense and closes locking device.It is applied to the fields such as electric power, distribution and electricity consumption.Contactor broadly time refer in industrial electro, utilize coil to flow through current induced magnetic field, make contact closure, to reach the electrical equipment of control load.Contactor is the important power control device for controlling motor start and stop and other electrical load break-makes.The adhesive of traditional contactor mainly realizes by the long-term galvanization of contactor coil, and the capacity of contactor is larger, and the electric current of needs is larger, and the time of adhesive is longer, and the electric energy of consumption is more.Along with the extensive use of contactor, a large amount of contactors arises at the historic moment.Contactor common at present mainly comprises the contact mechanism be made up of electromagnet, back-moving spring, contact and tactile bridge, iron core is had in electromagnet, the dynamic related contact of iron core, contact connects main circuit through touching bridging, back-moving spring connects dynamic iron core, when after magnet spool energising, electromagnet produce suction and inhale and, contact under the drive of dynamic iron core also inhale and, connect main circuit, motor rotation, after electromagnet coil power-off, suction disappears, and dynamic iron core is with moving contact to reset under the effect of back-moving spring, cut off main circuit, motor shuts down.This contactor is when voltage instability, and electromagnet suction is unstable, and contact closure is unreal, easily independently disconnects, cause the phenomenons such as unexpected power-off in use procedure.
And energy-saving type contactor mainly contains rectifier type and the large class of magneto two.Rectifier type contactor is owing to employing electronic device, and useful life obviously shortens, and failure rate is high.Permanent magnetism type contactor, need electronics monitors contactor to discharge and low-voltage release signal, failure rate is high, and causes contactor not discharge when monitoring circuit fault, there is more serious potential safety hazard.Therefore, the electric energy loss reducing contactor has great importance.Although there is magnetic maintenance technology in recent years, there is good improvement solving in these drawbacks that A.C. contactor exists, and because technology imperfection, cost are high, complex structure, particularly not easily accessed in automatic control circuit and make promoted extension limited.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-saving type contactor for problems of the prior art, solves short, the insecure problem of action in contactor useful life.
The technical solution of the utility model is:
A kind of contactor, comprise moving contact and fixed contact, the middle part of moving contact is connected with draw bar, the middle part of draw bar is surrounded with main pull-in winding, described draw bar upper end is provided with moving contact back-moving spring, the lower end of draw bar arranges draw bar hook, the lower end, side that corresponding draw bar has draw bar to link up with arranges electromagnetic location pin, the middle part of electromagnetic location pin is provided with the electromagnetic location cordon circle in parallel with main pull-in winding, electromagnetic location pin arranges electromagnetic location pin back-moving spring away from one end of draw bar, electromagnetic location pin is also provided with electromagnetic location locking contact, electromagnetic location locking contact is connected with main pull-in winding simultaneously.
The draw bar lower end of contactor provided by the utility model arranges hook, draw bar hook is at main pull-in winding and electromagnetic location pin coil electricity, when contactor moving contact and fixed contact adhesive, draw bar moves down, electromagnetic location pin moves to draw bar direction, thus draw bar hook blocks electromagnetic location pin, simultaneously, electromagnetic location pin drives electromagnetic location locking contact to cut off the power supply of main pull-in winding, makes its power-off.At this moment, utilize the elastic potential energy of fixed contact to provide moving contact to run required pressure, the power consumption utilizing electromagnetic location cordon circle minimum keeps electromagnetic location pin card position, keeps in touch device in attracted position, realizes energy-conservation object.When power is off, electromagnetic location pin resets under the traction of electromagnetic location pin back-moving spring, and moving contact resets under the effect of moving contact back-moving spring, and draw bar resets thereupon, and contactor discharges.By pure Design of Mechanical Structure, realize energy-conservation object, owing to there is not electronic device, useful life is constant, and does not need extra decompression monitoring circuit, so avoid the not releasable potential faults of contactor.It is simple that the utility model has structure, long service life, little power consumption, the reliable advantage of decompression release function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the attracting state figure of embodiment.
1 moving contact 2 fixed contact 3 main pull-in winding 4 moving contact back-moving spring
5 draw bar 6 draw bars link up with 7 electromagnetic location pin 8 electromagnetic location cordon circles
9 electromagnetic location pin back-moving spring 10 electromagnetic location locking contacts.
Embodiment
Be illustrated in figure 1 the structural representation of contactor provided by the utility model, comprise moving contact 1 and fixed contact 2.The middle part of moving contact 1 is connected with draw bar 5, and draw bar 5 upper end is provided with moving contact back-moving spring 4, and the middle part of draw bar 5 is surrounded with main pull-in winding 3, and the lower end of draw bar 5 arranges draw bar hook 6.The lower end, side that corresponding draw bar 5 has draw bar to link up with 6 arranges electromagnetic location pin 7.The middle part of electromagnetic location pin 7 is provided with the electromagnetic location cordon circle 8 in parallel with main pull-in winding 3, electromagnetic location pin 7 arranges electromagnetic location pin back-moving spring 9 away from one end of draw bar 5, electromagnetic location pin 7 is also provided with electromagnetic location locking contact 10, and electromagnetic location locking contact 10 is connected with main pull-in winding 3 simultaneously.
The utility model and the main distinction of traditional contactors are that the pressure hold mode after adhesive is different.In FIG, when the main pull-in winding 3 of contactor receives pickup signal, main pull-in winding 3 and electromagnetic location cordon circle 8 simultaneously electric adhesive, draw bar 5 drives moving contact 1 to fixed contact 2 direction action, adhesives both final, at course of action end, electromagnetic location pin 7 blocks draw bar hook 6, and contactor keeps attracting state, simultaneously, electromagnetic location pin 7 drives electromagnetic location locking contact 10 to cut off the power supply of main pull-in winding 3, and end-state as shown in Figure 2.When contactor receives release signal, electromagnetic location cordon circle 8 dead electricity, electromagnetic location pin 7 resets under the traction of electromagnetic location pin back-moving spring 9, and draw bar 5 drives moving contact 1 to reset under the elastic force effect of moving contact back-moving spring 4, and contactor recovers separated position.
