Description
Technical field
The present invention relates to a kind of magnetic latching relay, particularly relate to a kind of magnetic latching relay with new magnetic structure.
Background technology
Magnetic latching relay can reduce the energy consumption of relay coil effectively because coil does not need long-term power supply, meets the development main trend of current environmental protection and energy saving, thereby also is a main direction of relay development.
Existing magnetic latching relay is the unbalanced magnetic latching relay, and it generally includes contact portion, magnetic circuit part, pushing block.Contact portion generally includes normally closed static contact spring piece assembly, often opens static contact spring piece assembly and movable contact spring assembly, and these assemblies are packed in the plug-in mounting mode in the base, forms stable, contact portion reliably.Magnetic circuit partly generally includes U-shaped yoke, magnet steel, yoke, armature, making leaf spring, bobbin and coil windings; One end of U-shaped yoke carries out flattening of large deformation and forms flattening structure, fit on magnet steel and yoke then, and the other end is not flattened, in the bobbin hole of can packing into.The magnetic circuit part is assembled into whole of relay along the folk prescription of base in opening is packed base into, pushing block one end is through clamping, form hinge joint with the armature head, can in certain angle, rotate, make that can drive pushing block when armature movement moves, the other end of pushing block adopts projection cube structure to snap in the breach of movable contact spring and forms folk prescription to connection with overlapping mode, the moving displacement that armature in the magnetic circuit produces can be passed to movable contact spring.Under relay is in reset mode, when coil is applied pulse voltage, produce the pulse magnetic flux in the magnetic circuit loop, it makes armature move to the yoke direction, and promote the moving contact motion, and reset contact group (being the normally-closed contact group) is disconnected, set contact sets (being the normally opened contact group) is connected.After the pulse voltage, form the local flux loop, under the magneticaction of magnet steel, armature is remained on SM set mode, and keep set contact sets (being the normally opened contact group) in conducting state by the part of magnet steel, yoke, armature, the part of yoke; When coil is applied reverse impulse voltage, produce the pulse magnetic flux opposite in the magnetic circuit loop with the magnet steel flow direction, when this pulse magnetic flux equals the magnet steel magnetic flux, pulse magnetic flux and magnet steel magnetic flux interact, reach and offset, make armature not be subjected to the external force effect, under the counter-force effect of movable contact spring, armature is to leaving the motion of yoke direction, moving contact also moves under the effect of movable contact spring self counter-force, make reset contact group (being the normally-closed contact group) closure, set contact sets (being the normally opened contact group) disconnects.After the pulse voltage, armature is in free state, and movable contact spring and is kept reset contact group (being the normally-closed contact group) in conducting state under self mechanical counter-force effect.
Fig. 1 is the overall structural representation of existing magnetic latching relay; Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of existing magnetic latching relay, after as can be seen from the figure magnetic circuit is partly assembled and is finished, be folk prescription along the base of laterally packing in open-ended cavity, thereby improve the creepage distance of input and output; Fig. 3 is the decomposing schematic representation of the magnetic circuit part-structure of existing magnetic latching relay; Fig. 4 is the schematic diagram that the magnetic circuit of existing magnetic latching relay partly is in reset mode; Fig. 5 is the schematic diagram that the magnetic circuit of existing magnetic latching relay partly is in SM set mode.This magnetic latching relay comprise contact portion, magnetic circuit part, base 1 ' and pushing block 2 '.Contact portion generally include normally closed static contact spring piece assembly 41 ', often open static contact spring piece assembly 42 ' and movable contact spring assembly 43 ', these assemblies with the plug-in mounting mode pack into base 1 ' in, form stable, contact portion reliably.Magnetic circuit partly generally include U-shaped yoke 32 ', magnet steel 35 ', yoke 36 ', armature 33 ', making leaf spring 37 ', bobbin 31 ' and coil windings 34 '; U-shaped yoke in the magnetic circuit part at one end 321 ' carry out large deformation to flatten, form thin magnetic pole, magnet steel 35 ' pack into and flatten the position, the yoke 36 of packing into then '.At reset mode, magnet steel 35 ' the place place that flattens of yoke 32 ' one ends, yoke 36 ' with the yoke place of flattening with magnet steel 35 ' be clipped in the middle, this moment armature 33 ' under the effect of root making leaf spring 37 ' recuperability, remain on reset position.When apply in the magnetic loop pulse magnetic flux 51 ' after, armature one end 331 ' will move to yoke drives pushing block 2 ' move simultaneously.When armature 33 ' under the pulse magnetic effect with yoke 32 ' after contacting, magnet steel 35 ' magnetic flux 52 ' process yoke 36 ', armature one end 331 ', yoke one end 321 ' formation loop, with armature 33 ' maintain.This moment, armature 33 ' to pushing block 2 ' exert pressure and being passed on the movable contact spring maintained movable contact spring, made set contact sets (being the normally opened contact group) connect.When magnetic circuit being applied a 53 ' time of reverse impulse magnetic field, when 52 ' time of pulse magnetic flux 53 ' be equal to or greater than magnet steel magnetic flux, armature 33 ' under the double action of movable contact spring counter-force, reset reed 37 ' recuperability, be returned to reset mode.Under this state, reset contact group (being the normally-closed contact group) keeps on-state, magnet steel 35 ' cut little ice under the effect of movable contact spring self counter-force.The advantage of this structure is that the output (being contact sets) of relay and creepage distance, electrical distance between the input (being coil) can reach the reinforced insulation level in the VDE standard.But this existing magnetic latching relay structure is the unbalanced electromagnetic mechanism, and the set end adopts magnet steel to keep, thereby the bouncing time of its set contact sets is short, the pressure between the contact is big, and electric life is long; And reset terminal is not owing to there is the magnet steel effect, reset contact group (normally-closed contact group) only relies on the mechanical elasticity counter-force of movable contact spring to reset naturally, thereby the bouncing time of reset contact group (normally-closed contact group) is long, the pressure between the contact is little, and electric life is short, and bonding failure easily takes place.Under equal loading condition, the life-span of reset contact group (normally-closed contact group) is shorter, and the electric life of set contact sets (normally opened contact group) is very long.
