Embodiment
For the ease of those skilled in the art's understanding, the present invention is done further detailed description below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 1,2, shown in 4, the described relay of present embodiment is when the movable contact spring bidirectional-movement, all limits its movement velocity and reaches the slow slow a kind of relay of effect of putting of inhaling.This relay comprises: pedestal 1 is installed in fixed touching plate 3,4 and movable contact spring 5 and iron-core coil assembly 10 and actuator in the pedestal.Movable contact spring 5 comprises tip side 51 and elastic spring 52.Actuator is made up of with fixing magnet 8 on it a sliding part 7 that is held on elastic spring 52; Actuator through " push away, draw " elastic spring 52 and then drive whole movable contact spring 5, changes it under the effect of the magnetic force that the iron-core coil assembly 10 of energising produces between two diverse locations.
Among this embodiment,, the bidirectional-movement of movable contact spring is used the damping device speed limit for realizing the time-delay conversion of the position of the switch.Damping device adopts the fluid damping device.Like Fig. 1, the fluid damping device comprises damped motion part 6, base part housing 131.Damped motion part 6 one external parts are fixedly connected with the tip side 51 of movable contact spring 5, and the other end forms a cell body, cooperate with base part housing 131 to form a slit space, fill smectic fluid (damping grease) 12 in this space.For increasing the surface area of damped motion part; Damped motion part 6 and base housing are towards the inner surface in damping district and the sheet convex tendon 61,1311 that on the direction vertical with the actuator direction of motion, is crisscross arranged; These sheet convex tendons will be isolated the slit spatial that by damped motion part and base part housing 131 and will be slit into several littler slits; Damping grease 12 is filled in the slit between these staggered convex tendons, and is as shown in Figure 2.
After the energising of relay coil core assembly; After actuator receives the magnetic force execution; The retardance that movable contact spring 5 receives damped motion part 6 can not contact with the fixed touching plate of another side immediately; But under the elastic force effect of elastic spring 52, slowly promote damped motion part 6 continuous slips and contact completion time-delay switching with the fixed touching plate of another side until movable contact spring 5.
Fig. 3 is the second embodiment of the invention structural representation.It among this embodiment structure to movable contact spring one-way delay speed limit.Identical among the basic structure of this embodiment repeat circuit and first embodiment, just damped motion part 6 structures and embodiment one are different.Damped motion part 6 external parts are divided into damping end 62 and are free end with 63, two external parts of reset terminal, and damping end 61 stops the tip side 51 of movable contact spring in one direction, and reset terminal 63 stops the free end of elastic spring 52 on the movable contact spring on another direction.The other end of damped motion part 6 also forms a cell body, cooperates with base part housing 131 to form a slit space, fills smectic fluid 12 in this space, also the sheet convex tendon can be set in this space.
Like Fig. 3; After the energising of relay coil core assembly; After actuator is moved to the right by magnetic force; The retardance that movable contact spring 5 receives damped motion part 6 can not contact with the fixed touching plate of another side immediately, but under the elastic force effect of elastic spring 52, slowly promotes damped motion part 6 continuous slips and contact completion time-delay switching with the fixed touching plate of another side until movable contact spring 5.This process is identical with embodiment one.After the reverse energising of relay coil core assembly; The actuator reset force promotes elastic spring and drives whole movable contact spring 5 to left movement; Because movable contact spring 5 does not link together with damped motion part 6; Movable contact spring 5 breaks away from damped motion part 6 and accomplishes switching motion rapidly, and the free end of elastic spring promotes the reset terminal on the damped motion part simultaneously, and the damped motion part is resetted.
Like Fig. 5, also need the embodiment of one-way delay conversion for relay.Among this embodiment, sliding part 7 is connected with elastic spring on the movable contact spring, and damped motion part 6 external parts prop up the tip side of movable contact spring, and the damping device speed limit is implemented in the one-way movement of movable contact spring.Movable contact spring is identical with embodiment one, two situations when the direction of being obstructed (right side) is moved, and when movable contact spring 5 moved to undamped direction (left side), elastic spring drove movable contact spring and accomplishes switching motion rapidly, and flexible device 9 is used for resetting for promoting the damped motion part in addition.This elastic device 9 is arranged at the damped motion part other end.
In the foregoing description, described iron-core coil assembly 10 all can adopt E shape iron core, and this E shape iron core can and form by two U-shaped soft magnetic material spares together, and coil is on the center pillar of E sections core; Magnet on the said actuator also adopts U magnet, at U magnet the two poles of the earth flaky soft magnetic material spare is set, and the neutral gear of E sections core center pillar both sides is stretched at U magnet the two poles of the earth.
The foregoing description is the more excellent execution mode of the present invention; Need to prove; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these changes and distortion all should belong to the protection range of the appended claim of the present invention.
