Abstract
Back moving spring piece of the electromagnetic relay in L shape possesses two bend parts. Edgefold part extended from one free end of bend part is connected to yoke or pins-out. The other free end is integrated to a piece of movable contact spring, and fixed on armature. The correction method includes following steps: in time of correction, supplying voltage of bringing relay into action to the pins of winding; testing contacting states between the moving contact and the normal open contact; using adjusting thimble to press the said edgefold part extended from one free end of bend part horizontally or vertically makes winding generate enough magnetic force to overcome restoring force produced by the back moving spring piece, attracts and drives armature so as to cause contact state between the moving contact and the normal open contact. Advantages are: simplified operation and method for assembling relay, high efficiency and reducing investment on equipment.
Description
Technical field
The present invention relates to a kind of electromagnetic relay, the especially a kind of reset reed of electromagnetic relay and the bearing calibration of operation voltage thereof.
Background technology
Relay is as a kind of electromechanical compo, extensively apply in the field of the automatic control of various needs, electromagnetic relay generally comprises the magnetic conduction part of being made up of coil, iron core, yoke, armature, by movable contact spring, often drive the contact current-carrying part that static contact spring piece, normally closed static contact spring piece, contact are formed, reset reed or return spring, support plinth and guard shield.Relay comprises a series of performance parameters, and wherein operation voltage is one of several key parameters of decision relay performance, is the key in the relay correcting process.
In the electromagnetic relay of prior art, the bearing calibration of operation voltage has: the gap between correction movable contact spring, correction reset reed, correction return spring and correction armature and yoke etc.
Proofread and correct movable contact spring and can adopt mechanical means or laser means (referring to patent US4520254).Mechanical means is to reverse movable contact spring to make its generation mechanical deformation realize proofreading and correct purpose; Laser means is that the generation distortion realizes proofreading and correct purpose after making movable contact spring local heating.These two kinds of methods all cause the change of material property, surface appearance and/or the shape of correction place easily, and its stress concentration effect is strengthened, and have enlarged the probability of fatigue failure, thereby have had influence on the useful life of relay.In addition, laser means not only needs the equipment investment and the maintenance cost of great number, and can cause the vaporization of metal, the vaporizer of these metals can drop on the contact, cause the deterioration of relay contact performance, also can drop between the neither continuous conductor, cause the decline of insulation.Proofread and correct the method for reset reed, the one, realize proofreading and correct purpose by the distortion of reversing in this reed course of action place, cause the change of material property, surface appearance and/or the shape of correction place easily, its stress concentration effect is strengthened, enlarge the probability of fatigue failure, thereby had influence on the useful life of relay; The 2nd, proofread and correct fixedly reset reed one free-ended part (referring to patent US5864268), this mode requires that the shape of assembly precision height, correlated parts of relay is all very complicated, technology complexity.The method of proofreading and correct return spring is to make distortion realize proofreading and correct purpose by extension spring, and this is a kind of unidirectional method, and the assembling of spring and correction are difficult to realize automation.Gap (referring to patent US5369872) between correction armature and yoke requires the assembly precision of relay very high, technical process is long and complicated.
Summary of the invention
The object of the present invention is to provide a kind of reset reed of succinct electromagnetic relay and the bearing calibration of operation voltage thereof, make the electromagnetic relay assembling oversimplify, the correction of operation voltage is more easy, succinct and efficient, reduces the equipment investment when realizing automation.
The reset reed of the said electromagnetic relay of the present invention is L-shaped, is provided with two bending parts, extends bend at a free-ended bending part, and bend is connected with the yoke or the leading foot of electromagnetic relay; The movable contact spring of another free end and electromagnetic relay fuses and is fixed on the armature.Said connection can be selected for use and be clamped, and its corresponding reset reed is non-conductive; Said connection also can be selected riveted joint or welding for use, its corresponding reset reed conduction.
The bearing calibration of the said electromagnetic relay operation voltage of the present invention may further comprise the steps:
1), on the coil leading foot of electromagnetic relay, provides a given voltage that makes the electromagnetic relay action, the moving contact of detection electromagnetic relay and the situation that contacts of Chang Kai fixed contact;
2), with adjusting the bending part that extends the free end of bend on thimble level or the vertical above-mentioned reset reed of roof pressure, the magnetic force that makes coil produce enough overcomes the restoring force that reset reed produces, attract and driving armature, make moving contact contact with the Chang Kai fixed contact.
Owing to adopt special reset reed structure, the assembling of electromagnetic relay is oversimplified, and for the important performance characteristic of electromagnetic relay be that the correction of operation voltage provides a kind of new method, compare with existing bearing calibration, its advantage is that method is simple, efficient is high, has reduced the equipment investment that realizes automated production.The contrast of various bearing calibrations such as following table:

Embodiment
Following examples will the invention will be further described in conjunction with the accompanying drawings.
As Figure 1-3, a kind of reset reed 1 one free end 1.1 of electromagnetic relay is mechanically anchored on the armature 2, another free end 1.4 is connected on leading foot 3 or the yoke 4, for providing armature 2 behind the deenergization, relay replys the restoring force of initial conditions, thereby behind above-mentioned coil deenergization, the initial condition when driving armature 2 and being returned to relay and not switching on.Adjust the bend 1.3 at free end 1.4 places on the above-mentioned reset reed 1 by-thimble 14, can adjust this restoring force.
The connected mode of reset reed 1 and leading foot 3 or yoke 4 does not need to rivet or welding sequence for clamping, and reset reed 1 is non-conductive.Reset reed 1 also can adopt riveted joint or welding with the connected mode of leading foot 3 or yoke 4, and reset reed 1 is integrated and conduction with movable contact spring.As seen from the figure, leading foot 3 or yoke 4 have for reset reed 1 fixed shape.
Electromagnetic relay of the present invention is provided with reset reed 1, armature 2, leading foot 3, yoke 4, leading foot 5, litzendraht wire 6 and 7, coil 8, iron core, base 10, movable contact spring and other leading foot.The leading foot 3 of a conduction is connected with yoke 4.
After other parts assembling of relay is finished, pack into the cooperation place of yoke 4 and armature 2 of the parts that reset reed 1, movable contact spring and armature 2 are formed, free end 1.4 with reset reed 1 is installed on the leading foot 3 again, be welded on litzendraht wire 6 on the leading foot 3 again, litzendraht wire 7 is welded on the leading foot 5, finish whole assembly works of relay, send into subsequent processing at last and proofread and correct.Finish the relay part after the assembling, put into inspection machine, apply perpendicular or parallel power by thimble 14 at the bend 1.3 of reset reed 1 and proofread and correct in reset reed 1.When with the vertical mode timing, bent angle 1.2 angles on the reset reed 1 diminish, thereby increase recuperability; When with the parallel mode timing, then obtain the reverse effect with above-mentioned vertical mode timing, reduce recuperability.
Be provided with the hole that can be fixed on the armature 2 at reset reed 1 one free end 1.1, another free end 1.4 is provided with and can be installed on colluding on the leading foot 3 or on the yoke 4.
