Description
Technical field
The present invention relates to a kind of waveguide switch for microwave communication, particularly a kind of waveguide switch with heat abstractor, belongs to field of electromechanical technology.
Background technology
Waveguide switch is the Important Components that signal path controls, and is widely used for the radar of high-power output and the backup channel selector of communication transmitter; In the Microwave emission equipment being simultaneously also applied to Satellite Communication System and microwave observing and controlling engineering, the switching being commonly used to realize antenna in microwave power signal and unloading between passage is one of vital part of satellite-signal emission system.Waveguide switch is mainly used in high-power, high band microwave transmission, generally there are four external interfaces, need the product of backup to be connected with four interfaces by transmission line, by switching transmission means between four interfaces, thus realize the mutual switching of backup product, the reliability of whole star is improved with this.
Waveguide switch generally has three parts to form: control circuit part, drive motors part and radio frequency leading part.Radio frequency leading part is made up of leading stator and leading rotor precision-fit, and monolateral gap is about 0.03-0.05mm, and leading rotor is driven by drive motors and rotates.When waveguide switch transmission high-power RF signal, the heat that leading rotor produces dispels the heat mainly through the point cantact of radiation and ball ball bearing, therefore thermal diffusivity is poor, leading rotor and the leading stator temperature difference is caused to strengthen, leading rotor heat rises not enough to gap, and then stuck, directly cause waveguide switch to rotate and lost efficacy, affect the reliability of waveguide switch.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcoming waveguide switch leading rotor in prior art, to compare temperature with other positions of waveguide switch higher, and the device of unspecial heat radiation, the problem of radiating effect difference, with a waveguide switch for heat abstractor, the heat-sinking capability of waveguide switch effectively can be improved.
Technical solution of the present invention is: a kind of waveguide switch with heat abstractor, by control and driven unit (1), leading stator (2), leading rotor (3) and heat abstractor (4) form.Heat abstractor is made up of inner ring (5), outer shroud (6) and radiating wire (7).The dynamical system that control and driven unit (1) are waveguide switch, when controlling and driven unit (1) accesses extraneous input voltage, namely drive leading rotor (3) to rotate in the cavity of leading stator (2), thus realize the switching of different radio frequency transmission channel.Heat abstractor (4) is assemblied in the bottom of waveguide switch, the wherein bottom end face of the fixing assembling of inner ring (5) and leading rotor (3), the fixing assembling of outer shroud (6) is with on the shell of leading stator (2), and the radiating wire (7) by having favorable elasticity between inner ring (5) with outer shroud (6) is connected.During waveguide switch work, the upper heat produced of leading rotor (3) conducts on the shell of leading stator (2) by the inner ring (5) of heat abstractor, radiating wire (7), outer shroud (6), and then conduct on the mounting base of waveguide switch, define unimpeded delivered heat chain, avoid because of the hot rotation stuck phenomenon caused that rises of part.Described radiating wire (7) can bear the reciprocating motion in an angle of 90 degrees, does not increase extra frictional resistance and the moment of resistance, does not affect relatively rotating of leading rotor (3) and leading stator (2).
The present invention compared with prior art tool has the following advantages:
(1) the present invention devises the unexistent heat abstractor of traditional waveguide switch, effectively improves the heat-sinking capability of waveguide switch leading rotor, reduces the temperature of waveguide switch entirety;
(2) the present invention is optimized design to heat abstractor, on the radiating effect improving waveguide switch and product reliability basis, does not improve the staring torque that waveguide switch rotates, ensure that waveguide switch rotor can normal rotation.
