The utility model content
Problem to be solved in the utility model is to provide a kind of coaxial microwave switch, and its any service aisle keeps any duration of conducting, and product does not produce the heating phenomenon.
The utility model adopts following technical scheme: comprise microwave channel portion, control circuit, Electromagnetic Control portion, microwave channel portion comprises a public passage and several selector channels, control circuit comprises control section and drive part, Electromagnetic Control portion comprises ACTIVE media head and the return spring that is controlled by the microwave bridge circuit, it is characterized in that: described Electromagnetic Control portion comprises the bidirectional pulse electromagnet that several and selector channel are complementary, described bidirectional pulse electromagnet comprises the jacket casing cribbing, the activity permanent magnets, the control valve rod, two coil armature mechanisms, described two coil armature mechanisms are installed on jacket casing cribbing both ends, the activity permanent magnets is installed between two coil armature mechanisms, described two coil armature mechanisms comprise first armature and second armature, first armature is jacket casing formula structure, the control valve rod is sheathed in the trepanning of first armature, and the outer end of control valve rod links to each other with the ACTIVE media head by return spring; After the binary-coded decimal combination that described control section receives single-chip microcomputer input translates work order, the instruction of need being got through the selector channel is sent to drive part, send aforementioned need simultaneously and get through the reverse drive of the rest channels outside the passage and instruct to drive part, drive part carries out the bidirectional pulse electromagnet according to the instruction of control section or just or the power supply of reciprocal moment.
Its operation principle is: the work of this switch is that a plurality of microwave channels are by the optional one of microwave bridge circuit, when switch is received computer instruction, control section is by instruction gating one road shunting sign, produce the time broad pulse in one≤1 second simultaneously, under in above-mentioned signal and pulse, acting on, control section is exported the driving command of this passage, drive part is connected the driving power of this passage by instruction, control the magnetic field force of the bidirectional pulse magnet spool generation of this passage, promotion activity permanent magnets to the first armature direction move and with the tight adhesive of first armature, when the activity permanent magnets moves, drive control valve rod and ACTIVE media head and get through this passage, this moment, return spring was compressed; Simultaneously, this instruction makes the bidirectional pulse electromagnet reverse operation of last service aisle, the activity permanent magnets to the second armature direction move and with the tight adhesive of second armature, the control valve rod stretches to the second armature direction with the return spring effect under the nature, this moment, last selector channel disconnected.Realized multichannel any gating function thus.Since the time broad pulse effect, the conducting each time of drive current all is to finish in the short time (≤1 second), the electromagnet heating has little time to produce, drive current promptly disconnects, at the passage duration of work, by keeping conducting state with the magnetic force of the activity permanent magnets of the tight adhesive of first armature, need switch on except switching moment, need not to power up and keep.
The utility model has changed prior art and has adopted electromagnetic force to keep the technical scheme of passage conducting, product only carries out pulse power supply in the moment of conversion passage, driving switch switches, the impulse mgnet that adopts can keep operating state under cold situation, guaranteed that service aisle can not produce the heating phenomenon in the working hour of any duration, its long working life, failure rate is low, saves the advantage of electric energy in addition.
