Specific embodiment
Fail-safe type single-pole double throw RF switch of the invention is carried out with reference to the accompanying drawings and examples further detailed
Thin explanation and introduction.
As illustrated in fig. 1 and 2, fail-safe type single-pole double throw RF switch of the invention mainly includes by relay assembly
11 and the electromagnetic control system formed of cover plate assembly 10, the microwave transmission system that is made of transmission cavity component 8.
As shown in Figures 2 and 3, relay assembly 11 includes two pilot sleeves 2, first coil component 1, the second coil block
9, Relay base 3；Two pilot sleeves 2 are fitted into the through-hole opened up on Relay base 3 from top, and by the snap ring in through-hole
Pilot sleeve 3 is fixed on to the inside of Relay base 3.First coil component 1 and the second coil block 9 are inserted from above relay
Through-hole on seat 3, the upper contact with pilot sleeve 2.
As shown in Fig. 2,4 and 5, cover plate assembly 10 includes 6, two two small magnet steel, 4, two push rods 5, cover board transmission reeds
7；Push rod 5 passes through the via hole among cover board 6.The top of push rod 5 is equipped with cylinder groove 12, and small magnet steel 4 is installed by injection molding manner
In cylinder groove 12, the lower end riveting transmission reed 7 of push rod 5.
As shown in Fig. 2, the cylinder groove 12 on the top of push rod 5 is packed into pilot sleeve 2 from the lower section of Relay base 3.Push rod 5
Lower part and transmission reed 7 be mounted in the cavity of transmission cavity component 8, and can move up and down in the cavity；It is equipped in cavity
Inner conductor.The cover board 6 of cavity and cover plate assembly 10 is bolted, to make relay assembly 11, cover plate assembly 10 and pass
The fail-safe type single-pole double throw RF switch of defeated 8 assembly cost of chamber component invention.
Fail-safe type single-pole double throw RF switch of the invention, switching principle are as described below with action relationships:
First coil component 1 and component below collectively constitute microwave access one, the second coil block 2 and component below
Collectively constitute microwave access two.
It is not added under electricity condition, RF coaxial switchs the conducting of microwave access one, microwave access two disconnects.Microwave access one pair
The electromagnet portion answered, the magnetic steel magnetic pole contained in first coil component 1 is identical as the magnetic pole of small magnet steel 4 below, therefore same
Pole is repelled each other, and under the repulsive force effect of first coil component 1, small magnet steel 4 is pushed to move downward, due to small magnet steel 4, push rod 5, passed
Defeated reed 7 is fixed as one, therefore small magnet steel 4 drives push rod 5 and transmission reed 7 to move downward, transmission reed 7 and transmission cavity
Inner conductor contact in 8 cavity of component, therefore microwave access one is connected.Electromagnet portion corresponding to microwave access two, the second line
The magnetic steel magnetic pole contained in coil assembly 9 is different with 4 magnetic pole of small magnet steel below, therefore heteropolar attracting, in the second coil block 9
Attraction effect under, small magnet steel 4 drives push rod 5 and transmission reed 7 to move upwards, transmission reed 7 and transmission 8 chamber of cavity components
Inner conductor in body disconnects contact, therefore microwave access two disconnects.
In the power-on state, RF coaxial switch microwave access one disconnects, microwave access two is connected.Microwave access one pair
The electromagnet portion answered, the electromagnetic field that the power-up of first coil component 1 generates offset the magnetostatic field of magnet steel in first coil component 1, and
The electromagnetic field that the power-up of first coil component 1 generates is different with the magnetic pole of small magnet steel 4 below therefore heteropolar attracting, first
Under the attraction effect of coil block 1, small magnet steel 4 is attracted to move upwards, since small magnet steel 4, push rod 5, transmission reed 7 are fixed as
One, therefore small magnet steel 4 drives push rod 5 and transmission reed 7 to move upwards, in transmission reed 7 and transmission 8 cavity of cavity components
Inner conductor disconnects contact, therefore microwave access one disconnects.Electromagnet portion corresponding to microwave access two, the second coil block 9 add
The electromagnetic field that electricity generates offsets the magnetostatic field of magnet steel in the second coil block 9, under electromagnetic field and its that the second coil block 9 generates
4 magnetic pole of small magnet steel of side is identical, therefore homopolar-repulsion, and under the repulsive force effect of the second coil block 9, the small drive of magnet steel 4 is pushed away
Bar 5 and transmission reed 7 move downward, and transmission reed 7 is contacted with the inner conductor transmitted in 8 cavity of cavity components, therefore microwave is logical
Road two is connected.
When power is off, restore the conducting of microwave access one, the state that microwave access two disconnects.
