Description
The utility model relate to a kind of in same news road active and standby two transmitters power is sent into the equipment that antenna or load are switched mutually, particularly a kind of coaxial switch of active and standby two transmitters.
Coaxial switch (being coaxial switch) has two big classes at present at home and abroad, and two types, contact and contactless two big classes are promptly arranged, pulling and inserting type and rotary two kinds of patterns are arranged, comprise manual, automatic and full-automatic mode.On version, all partly form by motor, reductor control indication mechanism and main frame etc., pulling and inserting type is to adopt coaxial transmission line to break away from, reversing of position is removed the method for insertion more then, and rotary be to adopt many groups contact to disconnect or the methods of contact, two kinds of methods all can reach the purpose of the switching of power output.
The equipment of said method is mostly heavy, and it is unreliable to work, and the phenomenon of transmitter often occurs burning out, causes the reduction of great economic loss and broadcasting percentage.Having designed a kind of coaxial switch according to this situation the utility model, is on the basis of the rotary coaxial switch that U.S. MIC company produces, and has done sufficient improvement, has wherein improved running part, makes its structure small and exquisite simple, reliable operation; Next has improved control indicating section system, makes its control reliable; It three has improved delivery outlet and has been applicable to that 1KW-10KW different capacity grade do not change the version of main body; Its four processing that has improved contact point makes it easy to process, and above-mentioned improvement makes its this machine alleviate weight, has reduced cost, and technical indicator improves.
Active and standby two transmitters that the purpose of this utility model provides a kind of simple in structure, working stability are sent into the coaxial switch that antenna or load are switched mutually to power.
The utility model is to adopt such method to realize: coaxial switch is to adopt aluminium to cast a circular valve shape, around circular valve, have four ring flanges and connect output plug, a control board is installed on the top of circular valve, have micromachine and control assembly thereof on control board, motor is connected with rotor of output shaft axle on the circular valve by the input axle sleeve.Rotor is a platy structure in circular valve, has the rotating cylindrical body of protrusion at the two ends up and down of plate, has bearing retaining step at cylinder one end, and the lower end is assemblied in the bearing, and Bearing Installation is in the circular groove of circular valve bottom.The upper end is assemblied in the bearing on the upper cover plate.
On the rotor plate two sides by four copper coins up and down, with insulated bearing plate by screw on the rotor plate two sides.The side's of formation shape.
Respectively has a groove in the insulated bearing plate both sides, a rotation contact brace is housed in groove, rotation contact brace by screw in the groove of insulated bearing plate, and the rotation contact head that makes rotation contact brace leans out four jiaos at insulated bearing plate, is beneficial to contact with shell fragment on the contact base.
Two ends up and down in the rotor plate structure respectively have a groove, and row's shielding finger is housed in groove, and the end angle of shielding finger is a bending.Be beneficial to the rotation shielding.
Have four corresponding bonding plates around in circular valve, the bonding plate is to adopt screw on housing, has the bonding reed of transverse arrangement of turbo on the bonding plate.The end angle of bonding reed is a bending.Be beneficial to the contact shielding.Has a groove in the middle part of bonding plate, so that the contact head rotation time is passed through.
Around circular valve, have four corresponding ring flanges and connect port.An insulating disc is housed on ring flange, on insulating disc, pass through output plug of screw and a contact base, contact spring is equipped with at two ends up and down in contact base, one end of contact spring has a U-shaped head, be beneficial to and rotate contact head and contact, contact spring is to be fixed in the contact base by pressing plate, and pressing plate is by being connected to a fixed by the screw on the contact base.The insulating disc outside is fixed on the ring flange all around of circular valve by output flange.Output plug and contact base are electric conductor.
In the both sides of insulated bearing plate, have an oscillator plate perpendicular to insulated bearing plate, the oscillator plate is by being welded to connect the end at rotation contact brace.
The control device system is according to the working condition of active and standby transmitter.When needs are changed, stir control switch and make motor work in the control device system, motor output shaft drives the rotor rotation in the circular valve, put in place and 90 touch sensitive switch in the control device system by manual spanner when spending, cut off motor power, make the side indicator light on the control board bright simultaneously, show the wherein machine work of active and standby transmitter.Otherwise action together.
Rotor in the assembly, oscillator, shielding finger and rotation contact brace revolve when turning 90 degrees, rotation contact head on the rotation contact brace touches mutually with 16 reeds in the contact base, the power output that makes the delivery outlet ring flange makes the loss-free output of power by the output that output plug imports the delivery outlet ring flange of another 90 degree into.
When the assembly rotor revolves when turning 90 degrees, rotor touches mutually with reed on the ground shield, shielding finger links to each other with the circular valve upper and lower plates simultaneously, reach the effect of bonding, make transmission line form complete transmission cavity, with the mutual Isolated Shield in other chambeies, make its power not have the insertion loss, the mutual isolation of two complete output cavity is up to 60dB.
Last stage of transmitter tube sheet utmost point working voltage is 1.2 ten thousand volts, and active and standby two transmitters can only have one one to connect high-pressure work.When conversion, another one connects high-pressure work.This transfer process, the switching of two transmitter high pressure are to control by the high voltage interlock switch of coaxial switch.When coaxial switch revolves when turning 90 degrees, one of them connection of high voltage interlock switch makes one portion transmitter connect high-pressure work, and another switch disconnects, and transmitter does not have high pressure and is in stand-by state.
Transmission cavity in circular valve adopts mutual Isolated Shield, makes the loss-free transmission of its power.
Except that transmission line and each contact point, all the other each parts connect all to be made with polytetrafluoroethylene high-temperature-resistant high-pressure-resistant material, to absolute safe and reliable of the use of complete machine.
Output plug adopts beryllium-bronze to make, and perfect elasticity and conductivity are arranged, and opens circle at the endoporus spring of packing into, makes two contacts firmly, plays good transmitting effect.
The utility model has compared with prior art improved the isolation and the standing-wave ratio of machine widely, has reduced the power loss of transmitter, increases the rating cover ratio of transmitter.Standing-wave ratio brings up to 1.10 by original 1.15, and isolation is brought up to 60dB by original 58dB.It is reliable that this device has working stability in addition, and average conversion times can reach 10,000 times, and contact point is increased to 16 points by former 6, has improved the reliability of power, has significantly reduced the failure rate of transmitter.Simplified processing has improved operating efficiency simultaneously.Therefore this coaxial switch has not only reduced by 1/4th cost, and has increased economic benefit.This coaxial switch is suitable for the device of changing use with two transmitters.
