Description

The microminiature high sensitive relay

Technical field

The utility model relates to a kind of microminiature high sensitive relay, can be widely used in and do signal switching use on communication equipment, office equipment, teaching audio-visual equipment and Medical Devices, measuring instrument, security alarm and the detector etc.

Background technology

The 4078 type relays that use morely on the existing communication apparatus also adopt the structure of riveted unshakable in one's determination on yoke, and its leakage field is big, and suction is just little relatively, and iron core is stressed in the course of processing can produce irregular distortion, grasps and the degree of tightness of riveted is also difficult.Armature and the reed of going up riveted thereof are bending shape, the continuous adhesive work of armature, reed very easily effect of attrition working life.Coil position is subjected to the restriction of assembly space simultaneously, have to select the lead coiling in little line footpath for use, thereby increase resistance, coil heating is increased, and assembling also bothers.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of microminiature high sensitive relay is provided, easily makes, easily assembling, the suction-combining force be strong, and long service life.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the microminiature high sensitive relay is by the coil of institute's connecting band terminal pin on the armature of being with reed and the bobbin, unshakable in one's determination, yoke cooperates, pushing piece is connected with armature with movable contact spring respectively, have, following fixed contact, on, on the following static palping foot, following static contact and drive contact, the movable contact spring of movable palping foot is fixed on base plate and the fixed head, and work in coordination, base plate and fixed head link into an integrated entity, be inserted on the pedestal, be installed in the case and form, the bobbin of the coil of described band terminal pin, be fixed on the outside of fixed head and base plate, described iron core and yoke be holistic on, lower yoke, be separately fixed in the bobbin and fixed head on link into an integrated entity, and on, lower yoke cooperates with the armature of band reed on being connected fixed head and forms the loop.

Compared with prior art, advantage of the present utility model is: the coil that is around with the band terminal pin because of bobbin, be fixed on fixed head, the outside of base plate, there is bigger space to select for use than original coil, so can adopt the wire producing coil in big line footpath, reduce resistance, thereby reduce the caloric value of coil, the coil power dissipation I reaches 0.15 watt, yoke and iron core are holistic two yokes, directly be plugged in the bobbin from bobbin both sides symmetry, need do not rivet processing, bobbin can not be out of shape yet, influence its insulation resistance and compressive resistance, and easy to assembly, long service life.

And reed directly is riveted on the armature of horizontal shape, does not have wearing and tearing, and the leakage field of magnetic circuit is little simultaneously, then suction is big, highly sensitive, pickup time≤4.5 millisecond, release time≤1.5 millisecond.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

There are 6 uniform columniform joint pins two edges, fixed head 5 lower surface, have a through hole, two edges, upper surface that the facade of band groove is arranged in the middle of the termination.

Upper and lower yoke 6,4 cross sections are

Shape, the slide rail of the both sides of subsurface for constituting by cascaded surface.

In the middle of armature 10 1 terminations through hole is arranged, a surperficial rivet clasp has reed 11.

Respectively there is an inclined convex at pushing piece 9 opening two ends, and upper and lower laminar surface has one and two boss respectively.

The lead-out tablet 20 of the following static contact 19 of fixed contact 18, following static palping foot 8 and drive haptic element 21 is injection molded into one with base plate 17 under the band, there are 6 uniform through holes base plate 17 two edges, the centre is spaced two grooves, one projection is arranged in the middle of one termination, and two movable contact springs 16 that drive contact 15 are weldingly fixed on the end of lead-out tablet 20.

Last static contact 22 with last fixed contact 14, last static palping foot 7, respectively with the through hole sleeve on it on the joint pin of fixed head 5 two edges, and fixed head 5, base plate 17 usefulness through hole and the joint pin on it connected into integral body, thereby form a pair of by quiet, normally-closed contact that moving contact 18,15 constitutes on following static contact 19 and the movable contact spring 16, a pair of normally opened contact that constitutes by movable contact spring 16 and dynamic and static contact 15,14 on the last static contact 22.

The armature 10 of band reed 11 is placed on the centre position of fixed head 5 upper surfaces, and at the end of armature 10 clamping pushing piece 9, one boss of pushing piece 9 upper surfaces is held in the through hole on the armature lO, two inclined convex of opening part are buckled on the two edges on armature 10 surfaces, and two boss on the lower surface are clamped in the intersection end of movable contact spring 16.

Again with top belt coil 2, the bobbin 1 of terminal pin 3, be placed on the fixed head 5 of lower part, on, lower yoke 6,4 upper strata is drawn respectively and is inserted in the bobbin 1 from two ends, be divided into be close together on, lower floor, and subsurface utilizes the slide rail on its dual-side, in inserting groove on the fixed head 5 two edges facades from two ends respectively, be docked in the same plane, to go up, following two parts connect in aggregates, and utilize last static palping foot 7 on it, following static palping foot 8, movable palping foot 21, the through hole internal fixation that terminal pin 3 inserts on the pedestal 13, cover case 12 at last, relay is assembled into.

During use, electric current enters coil 2 from terminal pin 3, solenoid work produces suction adhesive armature 10, drives the pushing piece 9 that links into an integrated entity with armature 10 simultaneously and moves up, meanwhile the movable contact spring 16 that links together with pushing piece 9 is also moved up by drive, make the moving contact 15 on the movable contact spring 16, break away from the following fixed contact 18 on the static contact 19 down, and contact with last fixed contact 14 on the last static contact 22, finish a circuit and switch, make another line conduction.If no current feeds, then armature 10 is released, under the effect of reed 11, armature 10 restores to the original state, the pushing piece 9 that links together with armature 10 also sets back under action of gravity, moving contact 15 on the connected movable contact spring 16 is contacted with following fixed contact 18 on the following static contact 19 again, make an original circuit recover conducting.
