The movable plate unit 26 include large shunt piece 261, small splitter 263, movable contact spring 265, the first elastic slice 267 and
Second elastic slice 269.The large shunt piece 261, small splitter 263 and movable contact spring 265 are flaky texture, the layer-by-layer phase of three
Folded setting.Wherein, large shunt piece 261, small splitter 263 center outwardly protrude it is domed.First elastic slice 267 and dynamic spring
Piece 265 is stacked, and is located at the upper half side of movable contact spring 265.Second elastic slice 269 is stacked with movable contact spring 265, and is located at movable contact spring
It is half side under 265.The large shunt piece 261, small splitter 263, movable contact spring 265 center be formed with fluting 27, the fluting
27 are laterally extended and run through the front end of movable plate unit 26 along the length direction of movable plate unit 26, and the first elastic slice 267 is located at fluting 27
Upside, the second elastic slice 269 be located at fluting 27 downside, entire movable plate unit 26 be in intermediate jag double-rod structure.Hereinafter, dynamic
Blade unit 26 is located at the part of 27 upside of fluting, the upper half including large shunt piece 261, small splitter 263 and movable contact spring 265
And first elastic slice 267 be known as upper boom；Relatively part of the movable plate unit 26 on the downside of fluting 27, including large shunt piece 261,
Small splitter 263 is known as lower beam with the lower half of movable contact spring 265 and the second elastic slice 269.The upper boom and lower beam connect in rear end
It is connected in one, but is kept completely separate in front end.
The movable contact 28 is 2, is respectively arranged at the front end of upper boom and lower beam, opposite one by one with stationary contact 14.Due to
Upper boom is separated with the front end of lower beam, is in cantilever beam structure, has certain deformability, be so respectively arranged at upper boom and lower beam
Two movable contacts 28 of front end can be driven separately, contact or separate with corresponding stationary contact 14, form double rod, double-contact
Structure.Originally in implementing, the front end of the upper boom and lower beam is each formed with aperture, rivets with movable contact 28.Wherein, described first
The aperture of the front end of elastic slice 267 is bigger relative to large shunt piece 261, small splitter 263, aperture corresponding with movable contact spring 265, on
The movable contact 28 of side is connected to one when being riveted in aperture with large shunt piece 261, small splitter 263, movable contact spring 265,
But it is movably connected with the first elastic slice 267, the front end of the first elastic slice 267 is not fixed.The rear end of first elastic slice 267 is divided with big
The rear end shape of flow 261, small splitter 263 and movable contact spring 265 is fixedly attached to the by riveting at there is corresponding opening
The front end of two moving conductive pieces 24.Preferably, first elastic slice 267 is applied with certain pretightning force, front end is obliquely supported
It peaks on movable contact spring 265, so that upper boom under the action of no other external force slightly open towards 14 direction of stationary contact by deformation.
Second elastic slice 269, large shunt piece 261, small splitter 263, movable contact spring 265 pass through the movable contact 28 with lower section
Riveting be integrated.In the present embodiment, the surface of second elastic slice 269 is folded to be equipped with gasket.Preferably, second bullet
The relatively large splitter 261 in the front end of piece 269, small splitter 263, movable contact spring 265 forward extend out, for making with driving assembly 30
With, such driving assembly 30 can by pushing the second elastic slice 269 to drive lower beam mobile, make movable contact 28 on lower beam with it is corresponding
Stationary contact 14 contact or separation.In the present embodiment, the driving component 30 includes push rod 32, is formed on the push rod 32
The push plate 34 perpendicular with push rod 32, the push plate 34 are located between the rear end of quiet conductive sheet 12 and the front end of movable plate unit 26,
For pushing movable plate unit 26 far from quiet conductive sheet 12.The push rod 32 is also formed with slot 36, the slot be " recessed " shape,
" u "-shaped or " V " shape.The front end of second elastic slice 269 is stretched out except movable plate unit 26 and is inserted into the slot 36 of push rod 32
It is interior, for pushing movable plate unit 26 mobile towards quiet conductive sheet 12.As Figure 6-9, relay disconnects when initial, movable contact 28
Certain distance is separated between stationary contact 14, the large shunt piece 261 of movable plate unit 26 is supported in the push plate 34 of push rod 32 at this time, to movable plate
Unit 26 has certain active force, so that upper boom forms the preload that active force overcomes the first elastic slice 267 to the first elastic slice 267
Power.
When relay contact closure, push rod 32 is mobile (the present embodiment schema is to be moved to the left) with first direction, drives
The front end of second elastic slice 269 is mobile, and then drives entire lower beam mobile, is moved to the movable contact 28 on lower beam corresponding with lower section
Stationary contact 14 formed contact.The second elastic slice 269 deforms in the process, increases contact force.In addition, the movement of push rod 32
So that it is separated with upper boom to which the active force to upper boom disappears, the pretightning force of such first elastic slice 267 opens upper boom outward
It opens, drives the movable contact 28 of top to contact with the formation of the stationary contact 14 of corresponding top, as shown in Figure 2-5.Conversely, relay
When contact disconnects, push rod 32 is moved backward, and when push rod 32 is moved to its push plate 34 and the front end touching of movable plate unit 26, is pushed
Upper boom, lower beam move backward therewith, separate movable contact 28 with stationary contact 14, return to state shown in Fig. 6-9.Due to large shunt piece
261, small 263 center of splitter is arched upward outward, and push plate 34 pushes the front end of movable plate unit 26, and the part arched upward can form buffering,
It reduces contact resistance and improves the mechanical life of product.
Preferably, the movable plate unit 26 is arranged in parallel with the first moving conductive piece 22 in small―gap suture, in the work of electromagnetic field
With lower raising shock resistance current capacity.
Preferably, first elastic slice 267, the second elastic slice 269 can use high-temperature elastic material, as elastic stainless steel,
Elastic alloy steel etc., elasticity modulus is stablized under high or low temperature environment, is conducive to improve electrical endurance.
Figure 10-12 show another embodiment of the mechanism loading of invention relay, and difference essentially consists in: the
The rear end of one elastic slice 267 is fixed on the first moving conductive piece 22, and moving conductive piece component 20 is whole substantially Z-shape.Similarly, first
Upper boom is obliquely supported in the front end of elastic slice 267, and the second elastic slice 269 is fixed on lower beam and forward extends out to the slot 36 of push rod 32
Interior, the first elastic slice 267 pushes the movable contact 28 on upper boom to contact with corresponding stationary contact 14 by its pretightning force, the second elastic slice
269 push the movable contact 28 on lower beam to contact with corresponding stationary contact 14 by the drive of push rod 32, realize the closure of relay,
And separated by two movable contacts 28 of mobile drive of push rod 32 with stationary contact 14, realize the disconnection of relay.The present invention passes through
The reciprocating linear of push rod 32 is mobile, realizes the closure and disconnection of contact, and realize that two are moved by the pretightning force of the first elastic slice 267
The different closures of contact 28, have the characteristics that compact-sized, the processing is simple, reliable and stable.
It should be noted that the invention is not limited to above embodiment, creative spirit according to the present invention, this field
Technical staff can also make other variations, and the variation that these creative spirit according to the present invention are done should all be included in this hair
It is bright it is claimed within the scope of.
