Between, to strengthen the intensity at the pulling plate end.The assembly method of static contact and moving contact uses usual way, such as rivets.
Electric arc is generated when being separated in order to avoid moving contact with static contact, in moving contact, the one side of static contact in housing
It is provided with arc extinguishing magnet steel 24.By the setting of arc extinguishing magnet steel, the magnetic fields direction of magnet steel is that electric arc is made to be moved towards moving contact
Vertical direction movement, the magnetic field energy that magnet steel generates by between dynamic and static contact when the larger current disjunction issuable electric arc
It elongates, accelerates arc extinction, improve the folding ability and reliability of relay.In specific implementation, seat is formed in base enclosure inner wall
Body (plastic insulation material is made, can be with base enclosure same material) 25, extends L-type cavity 26 into pedestal from base enclosure outer wall,
Above-mentioned arc extinguishing alinco assembled is in L-type cavity, and such to set one be that positioning is convenient, second is that easily contact site establish magnetic field-
Generate arc extinguishing effect;Arc extinguishing magnet steel is square body, and arc extinguishing magnet steel one side sets the L being bonded with arc extinguishing magnet steel in L-type cavity
Type magnetic conductive board 27, the effect of magnetic conductive board are exactly to establish magnetic field together with magnet steel.
8 one side of assembly fixture is provided with skeleton 28, and in implementation, this skeleton is arranged vertically in housing, which has first
Platform 29, the second platform 30 and the tubular connection piece 31 for connecting the first platform, the second platform, the first platform, the second platform
Between formed electromagnet coil (not shown) placement space 32, the both ends of magnet coil extend to hull outside, are used for
Wiring;There is the passage 34 being inserted into for electromagnet core 33 in tubular connection piece;Above-mentioned armature is in below the second platform, electromagnetism
After iron coil is powered, the suction-combining force that iron core generates moves armature towards electromagnet ontology direction.
It is formed and connected by yoke 35 between skeleton and assembly fixture, one end of the yoke, which is plugged in be formed in assembly fixture, determines
Position, the other end extend to above the first platform and offer the insertion hole for the insertion of electromagnet core end.In specific implementation, yoke
The bending of iron upper end is treated to connect in the upper end of iron core 33 above the first platform, and middle part has a positioning protrusion 36, in assembly fixture
The second slot 37 is formed for being inserted into the middle part of yoke in the one side of the first slot 17, and the second slot bottom has for positioning protrusion
Yoke, is so assembled on assembly fixture by the socket 38 of insertion;The upper surface of first platform offer be recessed inwardly on yoke
The card slot 39 that the bending end at end is adapted, such yoke are formed with skeleton stent and positioned.
Spring support 40 is connected on yoke, which includes the first spring leaf 41, second spring piece 42, the first bullet
One end of reed is fixedly connected with one end of second spring piece, and forms angle between the first spring leaf and second spring piece, this
The first spring leaf, the second spring piece shown in embodiment is to be bent to form using a spring leaf from centre position.
First spring leaf, the junction of second spring piece offer notch 43, and one end of armature passes through the notch with being connected
Plate connects, and the other end of armature is in below the second platform, and after electromagnet coil power, iron core generates the suction-combining force by armature one end
Formed at notch upwards and towards the movement of electromagnet ontology direction, the other end of armature then declines;First spring leaf it is another
End is connected on yoke, i.e., has pilot hole 44 on the first spring leaf, have on yoke side wall in 45 plugging in fitting hole of connector
Form connection (such as riveting, screw connection).Armature in the application is that one end size is big, one end size is small as illustrated
Shape, the small one end of size pass through notch, and the big one end of size is in the suction-combining force generated below the second platform by iron core and is attracted,
In the course of work, to form fulcrum at notch, both ends are swung up and down armature;The lower end of electromagnet core is with sizes greater than iron core
The bulge loop 46 of body, after increasing electromagnet energization, the suction-combining force and magnetic field range of iron core, when electromagnet core assembles in place
Afterwards, bulge loop 46 is in the lower section of the second platform, but the top in armature, maintains gap therebetween, which is not more than
After electromagnet is powered, the suction-combining force scope of iron core generation.
Here the realization of the following two kinds connection mode may be employed with armature in second spring piece:
First way, the other end of second spring piece offers the pilot hole 47 through the first spring leaf, under armature
Surface is fixedly installed the lead 48 being interspersed in pilot hole.Such structure, lead are inserted into pilot hole, primarily serve
The guiding role that armature moves up and down;After electromagnet dead electricity, the disengaging of moving contact and static contact, mainly by the elastic force of movable contact spring
It resets upwards and the big one end of armature size falls, and the small one end of armature size drives and is pushed up on connecting plate 22 and drive pulling plate
23 rise.
The second way, the other end (the big one end of size) and the armature of second spring piece are in one below the second platform
End is fixedly connected (screw or bolt or the common connection mode of riveting).Like this, after electromagnet dead electricity, moving contact and stationary contact
The disengaging of head, on the basis of the first, adds the reset force of spring support, moving contact to be driven to depart from static contact.Cause
For electromagnet obtain it is electric after, the big one end of armature size moves upwards together with second spring piece, and passes through connecting plate, pulling plate
Drop-down, makes moving contact be contacted with static contact, and after electromagnet dead electricity, due to generating folder between the first spring leaf and second spring piece
Under the reset itself elastic force of angle and second spring piece, big one end moves downward with armature size, and such structure is compared with upper
The first way in face, structure is firm, and reset capability is strong.
