Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
As shown in Figure 1, cut-away view for the synchro switch magnetic latching relay 10 of one embodiment of the invention, a kind of synchro switch magnetic latching relay 10, including relay base 100, still assembly 200 is installed in relay base 100 and contacts the moving plate assembly 300 connected with still assembly 200. Electromagnetic assembly 400 and permanent-magnet component 500 it is also equipped with in relay base 100.
As in figure 2 it is shown, moving plate assembly 300 includes: moving plate 310, push card 320 and reed 330 of moving, the one end of reed 330 of moving is fixing with moving plate 310 to be connected, and the other end of reed 330 of moving is driven can be moved back and forth by push card 320.
In conjunction with, shown in Fig. 2 to Fig. 4, moving plate 310 offering location groove 311, push card 320 is installed on the groove 311 of location.
Push card 320 includes link 321 and promote-side 322, and link 321 is provided with limited bayonet 321a, and promote-side 322 offers promotion groove 322a, and push card 320 is connected with reed 330 of moving by limited bayonet 321a.
Reed 330 of moving includes the first spring leaf the 331, second spring leaf 332 and the 3rd spring leaf 333 of overlapped setting successively, and a surface of the 3rd spring leaf 333 cooperates with moving plate 310 and contacts. Moving and be additionally provided with movable contact 334 on reed 330, movable contact 334 is provided close to move on one end that reed 330 moves back and forth.
As it is shown on figure 3, the middle part of the first spring leaf 331 and the second spring leaf 332 is bending-type structure, the 3rd spring leaf 333 is straight slice structure.
It is noted that the operation principle of synchro switch makes it that adhesive bounce time to create significantly high requirement, and the generation knock-oned derives from contact and clashes into, when contact, the resilience caused. When carrying out resilience, the deformation of reed 330 of moving can be caused, if reed 330 of now moving only is provided the oppressive force to resilience by a piece of shell fragment, so can cause the result that shell fragment deformation is big, resilience is big. In the present invention, reed 330 of moving adopts three shell fragments to be connected with push card 320, when stationary contact 220 contacts with movable contact 334, push card, except contacting with the 3rd spring leaf 333, also can contact with the second spring leaf 332, and oppressive force suffered during such resilience can become much larger, under the effect of identical impact force, the deformation that reed 330 of moving designed by the present invention produces can be smaller, and resilience also can diminish, and such resilience time will reduce.
In conjunction with shown in Fig. 2 to Fig. 4, first spring leaf 331 is provided with and is connected the first fixing bending angle 331b of fixing bending angle 331a and the second coordinated with push card 320, first fixing bending angle 331a and the second fix bending angle 331b respectively with the both sides secure fit of the link of push card, the direction of the first fixing bending angle 331b bending of fixing bending angle 331a and the second is identical, and one end that the second spring leaf 332 is connected with push card 320 is straight slice structure.
As it is shown in figure 5, the 3rd spring leaf 333 is provided with the fixing bending angle 333a of shell fragment and shell fragment extruding flanging 333b, the fixing bending angle 333a of shell fragment is located on one end that the 3rd spring leaf 333 moves back and forth with shell fragment extruding flanging 333b.3rd spring leaf 333 is connected with push card 320 by the fixing bending angle 333a of shell fragment, and shell fragment extruding flanging 333b is near the surface of moving plate 310, and fixing bending angle 333a is identical with the knuckle direction that shell fragment extrudes flanging 333b for shell fragment.
To illustrate that, push card 320 is to carry out the fixing of front and back position by the fixing bending angle of first on the first spring leaf 331 fixing bending angle 331b of 331a and the second, and carries out the fixing of upper-lower position by coordinating of the fixing bending angle 333a of the first spring leaf 331 and the shell fragment on the 3rd spring leaf 333. By this fixed form make push card 320 only can in a less scope movable, therefore the action form of push card 320 just can be fixed up.
Said structure can be described as push card 320 and the snap-in structure of reed 330 of moving, and the design of this snap-in structure is advantageous in that, relies on coordinating of move reed 330 and push card 320, thoroughly limits the left and right of push card 320 and upper and lower range of activity. Additionally, design due to the fixing bending angle 333a of the shell fragment on the 3rd spring leaf 333, push card 320 is made to there is an oppressive force all the time, so no matter how push card 320 moves, the position of push card 320 and the 3rd spring leaf 333 is all relatively determined, thus ensureing when it does mechanical action the stability to the compressed position of the 3rd spring leaf 333 and compressing amount so that the concordance of synchro switch magnetic latching relay 10 action is significantly high.
Unique design about the 3rd spring leaf 333, to illustrate that, synchro switch magnetic latching relay 10 is in carrying out attracting process, can be subject to moving the elastic force of reed 330 and the electromagnetic force of generation, under the combined effect of two kinds of power, suffered power is more big, and the speed of synchro switch magnetic latching relay 10 adhesive is naturally more fast. As shown in Figure 5,3rd spring leaf 333 is provided with shell fragment extruding flanging 333b, make stationary contact 220 and movable contact 334 when open position, shell fragment extruding flanging 333b can contact with the surface of moving plate 310, thus producing very big elastic force, such synchro switch magnetic latching relay 10 is in attracting process, and suffered power will be greatly improved, so that the speed of adhesive improves, so the time required for adhesive will reduce.
When synchro switch magnetic latching relay 10 is in Guan Bi steady statue, shell fragment extruding flanging 333b separates certain distance with moving plate 310, when synchro switch magnetic latching relay 10 carries out release movement, from stationary contact 220 with movable contact 334 fully in contact with to the process being fully disconnected, shell fragment extruding flanging 333b and moving plate 310 not in contact with, from without synchro switch is produced impact with the time that the release of magnetic latching relay 10 is required.
Referring to Fig. 1, still assembly 200 includes still 210 and the stationary contact 220 being located on still 210, and stationary contact 220 contacts connection with movable contact 334.
Electromagnetic assembly 400 includes: first yoke the 410, second yoke 420 and be located at the coil 430 between the first yoke 410 and the second yoke 420.
Permanent-magnet component 500 includes fixed mount 510 and rotates the permanent-magnet steel 520 being installed on fixed mount 510, and push card 320 is connected by promoting groove 322a to drive with permanent-magnet steel 520.
Compared with prior art, the invention have the advantages that
1, the synchro switch magnetic latching relay 10 of the present invention snap-in design by push card 320 with reed 330 of moving, the reed 330 that makes to move locates relatively fixed position all the time with push card 320, push card 320 action consistency is made to improve, thus improving the concordance of synchro switch magnetic latching relay 10 movement time.
2, the synchro switch of the present invention extrudes the effect of flanging 333b with magnetic latching relay 10 by the shell fragment of the 3rd spring leaf 333, adds synchro switch magnetic latching relay 10 and is in elastic force suffered during open position, thus improve the speed of adhesive response.
3, the design that the reed 330 of moving of the synchro switch magnetic latching relay 10 of the present invention adopts three shell fragments to coordinate with push card 320, the resistance making stationary contact 220 suffered when contacting resilience with movable contact 334 is greatly improved, make the amplitude reduction of resilience, bounce time shortens, and meets the requirement of synchro switch.
