For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of miniature sealing magnetic keeps radio-frequency relay, comprises case 3, and contact system and magnetic circuit system are arranged in described case, and contact system and magnetic circuit system are spot-welded together; Contact system mainly is made of base, weld tabs, middle reed and contact, and magnetic circuit system mainly is made of yoke, magnet steel, coil, carriage, iron core, armature and putter component; The contact point of contact system is welded on the base, and middle reed point is welded on the weld tabs, and the weld tabs point is welded on the base; The yoke of magnetic circuit system and magnet steel composition yoke spot-welded together parts, yoke parts are contained between two coils; Iron core is contained in the coil, and an end unshakable in one's determination is contained on the carriage, and the other end unshakable in one's determination and yoke are riveted together; The putter component point is welded on the armature, and armature is adsorbed on the magnet steel surface.
Above-mentioned miniature sealing magnetic keeps being welded with rotating shaft in the radio-frequency relay in the middle of described armature.
Beneficial effect of the present invention: compared with prior art, the present invention can satisfy the radio circuit instructions for use, and its radio frequency parameter coupling is better, and the performance index of relay are stable, the dependability height.The present invention has following characteristics:
(1) the present invention is a kind of miniature sealed direct-current magnetic latching relay, and its volume is little, and is in light weight, anti-vibration, impact property index height, low distributed capacitance.
(2) armature assembly of the present invention adopts the rotary shaft structure, and the performance index of relay are stable, the dependability height.
(3) uniqueness of contact system of the present invention design makes radiofrequency characteristics (inserting loss, isolation, voltage standing wave ratio, radio-frequency power transmittability, characteristic impedance) parameter matching better, and the radiofrequency signal that is widely used in (0～6) GHz frequency range is switched.
The present invention is to the unique design of the structure of existing contact system and magnetic circuit system, the middle reed parts of contact system of the present invention adopt integrated structure (because of contact portion has two contacts, cooperate and two reeds of contact contact need, the present invention guarantees can contact with two contacts after adopting a middle reed by weld tabs of spot welding), the armature assembly of magnetic circuit system adopts the rotary shaft structure (to be welded with rotating shaft in the middle of armature, when rotating, armature rotates) by rotating shaft, make the mechanical parameter (contact gap of this miniature seal radiofrequency electromagnetic relay contact system, contact overtravels etc.) design suitably, the radiofrequency characteristics parameter matching is better, is applicable to that the radiofrequency signal of (0～6) GHz frequency range is switched.

Embodiment
Embodiment 1.As shown in Figure 1, comprise case 3, contact system 1 and magnetic circuit system 2 are housed in case 3.Contact system 1 mainly is made of base 4, weld tabs 5, middle reed 6 and contact 7, and magnetic circuit system 2 mainly is made of yoke 8, magnet steel 9, coil 10, carriage 11, iron core 12, armature 13 and putter component 14, is welded with rotating shaft 15 in the middle of armature 13; 7 of the contacts of contact system 1 are welded on the base 4, and 6 of middle reeds are welded on the weld tabs 5, and 5 of weld tabs are welded on the base 4; The yoke 8 and the magnet steel 9 composition yoke parts spot-welded together of magnetic circuit system 2, these yoke parts are contained between two coils 10; Unshakable in one's determination 12 are contained in the coil 10, and 12 1 ends unshakable in one's determination are contained on the carriage 11, and 12 other ends unshakable in one's determination and yoke 8 are riveted together; 14 of putter components are welded on the armature 13, and armature 13 is adsorbed on magnet steel 9 surfaces.
During making, with reed parts (integrated structure) in the middle of weld tabs 5 and middle reed 6 compositions spot-welded together, elder generation spot welding contact 7 on base 4 then is welded in middle reed parts point on the base 4 in contact system 1, forms contact system (as shown in Figure 2).With rotating shaft 15, putter component 14, armature 13 composition armature assemblies spot-welded together, in magnetic circuit system 2 with yoke 8, magnet steel 9, coil 10, carriage 11, iron core 12 assembles (during assembling by the mode of riveting dress, earlier with yoke 8 and magnet steel 9 composition yoke parts spot-welded together, with the iron core 12 1 ends carriage 11 of packing into, the coil 10 of again iron core 12 being packed into, last yoke parts are packed between two coils 10, the other end with unshakable in one's determination 12 and yoke 8 riveted joints), load onto armature assembly and form magnetic circuit system, at last contact system 1 and 2 postweldings of magnetic circuit system are become relay block, and with case 3 sealings by fusing, get final product (as shown in Figure 1).
Operation principle: left working gas gap magnetic flux and right working gas gap magnetic flux that magnet steel 9 produces, the preceding excitation coil of relay is applied the pulse voltage of coil rating value, the electromagnetism magnetic flux that is produced is because of opposite with the permanent magnet flux direction in left working gas gap, simultaneously identical with the permanent magnet flux direction in right working gas gap, the resultant flux of right air gap is greater than the resultant flux of left air gap, and armature 13 is opened from left magnetic pole and inhaled to the right that magnetic pole makes the left closing of contact.After the preceding excitation coil outage, armature 13 remains on this state under the effect of permanent magnet flux.When the back excitation coil of relay applied the pulse voltage of coil rating value, armature 13 was from right magnetic pole involution to left magnetic pole and then make the right closing of contact, and remains on this state after the outage, finishes the switching of a radiofrequency signal circuit.
