Abstract
The present invention discloses an electromagnetic switch of a starter motor. The electromagnetic switch comprises an armature, a housing, a coil, a guide tube, a bottom cover, a piston ring and permanent magnetic steels. The electromagnetic switch is characterized in that an iron core extends from the top of the housing (2), and the guide tube (4) is arranged outside the iron core; the armature (1) is arranged inside the guide tube (4), and the piston ring (6) is disposed between the armature and the guide tube for tight fit; the coil (3) is arranged between the guide tube and the housing; and two permanent magnetic steels (7) are disposed in a middle segment of the coil, and the same polarities of the two magnetic steels are arranged inwardly. By using the electromagnetic switch provided by the invention, the power consumption is reduced, and the block of the armature is prevented.
Description
Technical field
The present invention relates to a kind of switch, relate in particular to a kind of electromagnetic switch of actuating motor.
Background technology
The structure of traditional helix tube type cylindricality traction electromagnetic switch is: the outside is the magnetic conduction casing that a tubulose ferromagnetic material consists of, the bottom that the magnetic conduction casing bottom is made by ferromagnetic material seals, the inner tubular coil of placing of magnetic conduction casing is equipped with guide pipe in the coil, armature is reciprocating motion in guide pipe.
The electromagnetic switch of traditional structure is simple in structure, and is easy to manufacture, good seal performance.Weak point is: the electromagnetic switch heat dispersion is poor, produce larger confining force and must continue to pass into larger maintenance electric current, and this not only wastes electric energy, and coil is overheated, can make operational failure, thereby need to be designed to magnetic maintenance structure.There is armature in traditional guide pipe to the guidance mode of armature the contact area with guide pipe is larger at the volley in addition, produces the problem of the easy clamping stagnation of armature.
Summary of the invention
Technical problem to be solved by this invention is: proposed a kind ofly can reduce the not electromagnetic switch of the actuating motor of clamping stagnation of energy consumption, armature.
Solve this technical problem, technical scheme of the present invention is: a kind of electromagnetic switch of actuating motor, formed by armature, housing, coil, guide pipe, bottom, piston ring, permanent magnetic steel, the stretched iron core in the upper end of housing, the outer guide pipe that has unshakable in one's determination, linking is positioned at guide pipe, there is piston ring to closely cooperate between armature and the guide pipe, be coil between guide pipe and the housing, the stage casing of coil arranges 2 permanent magnetic steels, and 2 magnet steel same polarities are inwardly put.
Housing, bottom, armature are made by permeability magnetic material, and piston ring is made of plastics.
Compared with the prior art, the present invention solves magnetic and keeps the method for problem to be: be the I state of armature such as Fig. 1, hereinafter referred to as state I, put permanent magnetic steel 7 in coil 3 stage casings, permanent magnetic steel 7 provides confining force for armature 1.Magnetic circuit is got back to again permanent magnetic steel 7 by permanent magnetic steel 7, housing 2, armature 1.When state I, adding forward voltage to solenoid winding 3, armature 1 moves downward with the bottom 5 of lower end and contacts, behind coil blackout, provide confining force by permanent magnetic steel for armature 1, at this moment be that the 2nd state I I of armature is hereinafter to be referred as state I I, see Fig. 2, magnetic circuit is got back to again permanent magnetic steel by magnet steel 7, housing 2, bottom 5, armature 1 during state I I.When coil added reverse voltage, armature 1 moved upward and contacts with the iron core of the housing 2 of upper end, and behind the coil blackout, permanent magnetic steel provides confining force for armature, and armature is got back to state I (seeing Fig. 1).This structure can provide larger confining force for armature, and the confining force of two states is basic identical, and the operation voltage of two states is more or less the same.
The method that the present invention solves the easy clamping stagnation problem of armature is: change traditional mode that armature motion is led with guide pipe, this guidance mode armature at the volley contact area with guide pipe is larger, so that product easy clamping stagnation of armature when powering up, armature is motionless or move not in place.Increase now the piston ring 6 (seeing Fig. 2) that plastic material is made between guide pipe 4 and the armature 1, utilize plastics surface Paint Gloss to contact with guide pipe and reduce friction.Piston ring is the plastics banded structure, is centered around during assembling around the armature, makes it to closely cooperate with guide pipe.The piston ring of this structure has the effect of self adaptation and self-lubricating, greatly reduced armature at the volley with the friction area of parts and components on every side, solved the easy clamping stagnation of armature, be failure to actuate or moved problem not in place.
Compared with prior art, the beneficial effect that has of the present invention is:
A kind of helix tube type electromagnetic switch structure that magnetic keeps function that has is provided, this structure can provide larger state confining force, greatly reduces simultaneously coil power consumption, temperature rise, has effectively reduced the overall dimension of electromagnetic switch, high, the failure rate is low of reliability, assemble simple and easy, production efficiency is high.
Description of drawings
Fig. 1,2 is structural representation of the present invention.
Among the figure: 1 armature, 2 housings, 3 coils, 4 guide pipes, 5 bottoms, 6 piston rings, 7 permanent magnetic steels.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment: as shown in Figure 1, housing 2 the stretched iron core in upper end, unshakable in one's determination outer have guide pipe 4, armature 1 to be positioned at guide pipe 4 to pump, have piston ring to closely cooperate between armature and the guide pipe.Be coil between guide pipe and the housing, 2 permanent magnet magnet steel are put in the stage casing of coil, and 2 magnet steel same polarities are inwardly put, for armature provides confining force.
When armature was in state I, such as Fig. 1, magnet steel provided the confining force of F1 for armature, when coil added forward voltage, coil produced the magnetic field force of F2, and coil magnetic field power moves downward with the bottom of lower end armature greater than the magnet steel confining force and contacts, armature is transformed into state I I, such as Fig. 2.When state I I, magnet steel provides the confining force of F3 for armature, and when coil added reverse voltage, coil produced the magnetic field force of F4, and coil magnetic field power moves upward armature greater than the magnet steel confining force and contacts with the iron core of housing, and armature is returned to state I.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the claim scope of the present invention variation, the modification of the above embodiment.
