Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Fig. 1,2,4, the relay described in the present embodiment is when movable contact spring bidirectional-movement, all limits its movement velocity and reaches the slow a kind of relay putting effect of slow suction.This relay comprises: pedestal 1, is arranged on fixed touching plate 3,4 in pedestal and movable contact spring 5 and iron-core coil assembly 10 and actuator.Movable contact spring 5 comprises tip side 51 and elastic spring 52.Actuator is made up of with the magnet 8 be fixed thereon the sliding part 7 that is held on elastic spring 52, actuator passes through " push away, draw " elastic spring 52 and then drives whole movable contact spring 5 under the effect of the magnetic force of iron-core coil assembly 10 generation of energising, makes it change between two diverse locations.
In this embodiment, for realizing the time-delay conversion of the position of the switch, to the bidirectional-movement of movable contact spring damping device speed limit.Damping device adopts fluid damping device.As Fig. 1, fluid damping device comprises damped motion part 6, base part housing 131.Damped motion part 6 one external part is fixedly connected with the tip side 51 of movable contact spring 5, and the other end forms a cell body, coordinates formation one slit space with base part housing 131, fills 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 is crisscross arranged on the direction vertical with the actuator direction of motion, the slit that the slit compartition isolated by damped motion part and base part housing 131 becomes several less by these sheet convex tendons, damping grease 12 is filled in the slit between these staggered convex tendons, as shown in Figure 2.
When after the energising of relay coil core assembly, actuator is by after magnetic force execution, the retardance that movable contact spring 5 is subject to 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 and constantly slide until movable contact spring 5 has contacted time delay with the fixed touching plate of another side switches.
Fig. 3 is second embodiment of the invention structural representation.It is the structure to movable contact spring one-way delay speed limit in this embodiment.The basic structure of this embodiment repeat circuit is identical with the first embodiment, is that damped motion part 6 structure and embodiment one are different.Damped motion part 6 external part is divided into damping end 62 and reset terminal 63, two external parts to be free end, 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 movable contact spring in the other directions.The other end of damped motion part 6 also forms a cell body, coordinates formation one slit space with base part housing 131, fills smectic fluid 12, also can arrange sheet convex tendon in this space in this space.
As Fig. 3, when after the energising of relay coil core assembly, actuator is by after magnetic force action to the right, the retardance that movable contact spring 5 is subject to 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 and constantly slide until movable contact spring 5 has contacted time delay with the fixed touching plate of another side switches.This process is identical with embodiment one.After relay coil core assembly is oppositely energized, actuator reset force promotes elastic spring and drives whole movable contact spring 5 to left movement, because movable contact spring 5 and damped motion part 6 do not link together, movable contact spring 5 departs from damped motion part 6 and completes switching motion rapidly, the free end of elastic spring promotes the reset terminal on damped motion part simultaneously, and damped motion part is resetted.
As Fig. 5, it is also embodiment that relay needs one-way delay to change.In this embodiment, sliding part 7 is connected with the elastic spring on movable contact spring, and damped motion part 6 external part props up the tip side of movable contact spring, implements damping device speed limit to the one-way movement of movable contact spring.Movable contact spring is identical with embodiment one, two situation when moving to direction of being obstructed (right side), and when movable contact spring 5 moves to undamped direction (left side), elastic spring drives movable contact spring to complete switching motion rapidly, and another flexible device 9 is used for resetting into promoting damped motion part.This elastic device 9 is arranged at the damped motion part other end.
In above-described embodiment, described iron-core coil assembly 10 all can adopt E shape iron core, and this E shape iron core also can be formed by two U-shaped soft magnetic material parts together, and coil is around on the center pillar of E shaped iron core; Magnet on described actuator also adopts U magnet, arranges flaky soft magnetic material part at U magnet the two poles of the earth, and the neutral gear of E shaped iron core center pillar both sides is stretched at U magnet the two poles of the earth.
Above-described embodiment is preferrred embodiment of the present invention; it should be noted that; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change and are out of shape the protection range that all should belong to the claim appended by the present invention.
