Description
Technical field
The present invention relates to a kind of magnetic latching relay, particularly relate to a kind of magnetic latching relay of clapper-type armature structure.
Background technology
Magnetic latching relay is a kind of new type of relay grown up in recent years, is also a kind of automatic switch.The same with other electromagnetic relays, circuit is played and automatically connects and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect relying on permanent-magnet steel completely, and the conversion of its on off state leans on the pulse electrical signal of one fixed width to trigger.
Magnetic latching relay is magnet steel part due to assembled inside, and magnet steel is harder crisp, and easily broken under stressing conditions, therefore the fixed form of magnet steel is the difficult point in magnetism holding type relay development process.
Magnet steel is normally contained in the middle of iron core or is contained in the middle of yoke by the magnetic latching relay of the clapper-type armature structure of prior art, when magnet steel is contained in the middle of iron core, iron core is cut into two sections, is then connected in the middle of iron core by magnet steel.Same, when magnet steel is contained in the middle of yoke, is also yoke will be cut apart with a knife or scissors, then magnet steel is connected in the middle of yoke.This magnet steel mounting means of prior art, on the one hand, easily causes the deviation of magnet steel position; On the other hand, too increase the manufacture difficulty of the magnetic latching relay of clapper-type armature structure, meanwhile, also can cause the increase of cost of manufacture.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, a kind of magnetic latching relay of clapper-type armature structure is provided, that magnet steel is arranged between iron core and yoke, and utilize the location structure between yoke and bobbin, on the one hand, fixing between yoke and bobbin is realized, on the other hand, can magnet steel be accurately positioned between iron core and yoke, there is magnet steel good positioning effect, relay assembles easily, manufacture difficulty reduces and the feature of cost of manufacture minimizing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of magnetic latching relay of clapper-type armature structure, comprises magnetic circuit part; Described magnetic circuit part comprises bobbin, magnet steel, iron core and yoke; Iron core is plugged in the centre bore of bobbin; The bobbin of described centre bore one end is provided with deep gouge, one end of iron core is stuck in the deep gouge of bobbin, the one side of described yoke is fixed on the bobbin place of described centre bore one end by the location structure laminating between yoke and bobbin and is pressed in by described magnet steel in the deep gouge of described bobbin, the one side of magnet steel contacts with one end of described iron core, and the another side of magnet steel contacts with the one side of described yoke.
Described yoke and the location structure between bobbin comprise the corresponding through hole of several and described convex bud of the one side being arranged on several convex buds on bobbin and being arranged on described yoke, and each convex bud of bobbin matches to realize locating with the corresponding through hole of yoke respectively.
Fixing between described yoke and bobbin, for adopting plastic hot melt to scald riveting technology, will be engaged in the plastics melting of the convex bud of yoke through hole, make convex bud scald riveting in yoke through hole, thus be fixedly connected with bobbin by yoke.
The through hole of described yoke is stepped hole, fixing between described yoke and bobbin, is the plastics melting of the convex bud at the step place by being engaged in yoke through hole, makes convex bud scald the step place of riveting at yoke through hole, thus is fixedly connected with bobbin by yoke.Certainly, also can be adopt straight hole.
Location structure between described yoke and bobbin comprises the semi-enclosed cavity being arranged on bobbin end, and one end of described yoke is inserted in semi-enclosed cavity of bobbin end, and by interference fit, yoke is fixedly connected with bobbin.
Location structure between described yoke and bobbin comprises the some colloid be bonded between yoke and bobbin, is realized location and is fixed between yoke and bobbin by some glue connected mode.
It is be provided with head in one end of iron core that one end of described iron core is stuck in the deep gouge of bobbin, and the head of iron core is stuck in the deep gouge of bobbin.
The magnetic latching relay of a kind of clapper-type armature structure of the present invention, after the moving spring armature part of assembling clapper-type armature structure, due to the effect of magnet steel, at relay reset mode, yoke, magnet steel, iron core and armature form not closed magnetic circuit loop, dynamic spring counter-force is greater than the suction of magnetic field to armature, and therefore relay remains on reset mode.When the actuating of relay, coil leads to direct impulse voltage, the magnetic field that coil produces and the magnetic field Downward addition that magnet steel produces, the suction of magnetic field to armature is greater than the counter-force of dynamic spring, armature is inhaled, armature drives dynamic spring contact part, relay closes, after pulse voltage is removed, yoke, magnet steel, iron core and armature form closed magnetic circuit loop, the suction of magnetic field to armature is greater than the counter-force of dynamic spring, relay remains on closure state, when relay resets, coil leads to a reverse impulse voltage, the magnetic field that coil produces oppositely superposes with the closed magnetic field that magnet steel produces, dynamic spring counter-force is greater than the suction of magnetic field to armature, dynamic spring band moving armature resets.
The invention has the beneficial effects as follows: on the bobbin of described centre bore one end, be provided with deep gouge due to have employed, one end of iron core is stuck in the deep gouge of bobbin, the one side of described yoke is fixed on the bobbin place of described centre bore one end by the location structure laminating between yoke and bobbin and is pressed in by described magnet steel in the deep gouge of described bobbin, the one side of magnet steel contacts with one end of described iron core, the another side of magnet steel contacts with the one side of described yoke, and magnet steel can be accurately positioned between iron core and yoke by this structure, owing to have employed, several convex buds are set on bobbin, in the one side of described yoke, several through holes corresponding with described convex bud are set, by each convex bud of bobbin respectively with the matching of the corresponding through hole of yoke, and adopt plastic hot melt to scald riveting technology, the plastics melting of the convex bud of yoke through hole will be engaged in, convex bud is made to scald riveting in yoke through hole, thus yoke is fixedly connected with bobbin, this fixed form, assembling between yoke and bobbin is more prone to, thus reduce the manufacture difficulty of relay and reduce the cost of manufacture of relay.
Below in conjunction with drawings and Examples, the present invention is described in further detail; But the magnetic latching relay of a kind of clapper-type armature structure of the present invention is not limited to embodiment.
