Referring to fig. 2, one end that frame 1 is equipped with armature slot 101 is equipped with three pairs of 102 (in practical applications, frame 1 of support leg
Support frame 102 for being connect with contact system, complete relay is formed by electromagnetic driving system and contact system), armature 2
Middle part connect with intermediate a pair of of 102 hinge of support leg, referring to Fig. 1, the first magnetic pole core 9, the second magnetic pole core 8 and magnet steel 6
One end both passes through coil slot 103 and extends in armature slot 101, and magnet steel 6 extends in one end in armature slot 101 and armature 2
Portion's contact, referring to Fig. 3, pole plate 7 includes magnetic-conductance portion 701 and non-magnetic portion 701, the other end and magnetic-conductance portion of the first magnetic pole core 9
701 contacts, the other end of the second magnetic pole core 8 contacts with non-magnetic portion 702, and the other end of magnet steel 6 is at least a part of and magnetic conduction
The contact of portion 701, first coil 4 and the second coil 5 are connected and current direction is opposite.
It should be noted that E type frame 1 is common part in common maintenance relay, but general maintenance and
The part of the relay of non-maintenance is not general, when preparing non-maintenance relay, needs to redesign.And in the present embodiment
The relay that is constituted of electromagnetic driving system, for the non-holding using the general purpose accessory of maintenance relay, being prepared
Type relay greatly reduces radio-frequency relay design cost in this way, improves the versatility of part, effectively reduces and be prepared into
This.
The working principle of the radio-frequency relay electromagnetic driving system is briefly described below:
When first coil 4 and the second coil 5 are powered, first coil 4 generates magnetic field identical with 6 direction of magnet steel, pushes
Armature 2 leaves first coil 4, and the second coil 5 generates the magnetic field contrary with magnet steel 6, attraction armature 2 close to the second coil 5,
Final armature 2 rests in one end (extending to one end of armature slot 101) of the second magnetic pole core 8 where the second coil 5.When
When one coil 4 and the second coil 5 power off, due to the second coil 5 one end (one end i.e. in coil slot 103) with it is non-magnetic
Portion 702 contacts, and the magnetic field that magnet steel 6 generates cannot in the right half part (i.e. part locating for the second coil 5) of electromagnetic driving system
Complete magnetic circuit is formed, the first magnetic pole core 9 where can only driving armature 2 to first coil 4 is mobile, and rests in initial bit
It sets, the electromagnetic driving system realizes non-maintenance function in this way.It should be noted that in practical applications, it only need to be by magnetic pole
Plate 7 is changed to perfact magnetic conductor (i.e. all magnetic-conductance portions), and the magnetic field that magnet steel 6 generates after two coil blackouts can be in electromagnetic driving system
Right half part form complete magnetic circuit, the one end for the second magnetic pole core 8 for being maintained at armature 2 where second coil 5 (extends to
One end of armature slot 101), and then realize maintenance function.
In addition, when armature 2 is by magnetic field suction, will drive the pushing mechanism 3 being arranged on armature 2, by pushing away referring to Fig. 6
Motivation structure 3 drives the movable contact spring in the contact system of radio-frequency relay, so that movable contact spring is contacted with static contact, realizes contact system
Conducting.
