And transmitting the signal from a fixing signal one frame frame movement, when signal is by slip ring, a key constraints peak transfer rate is high, and the waveform of signal is because impedance is discontinuous frequently, so that reflection distortion.The conversion of the transmission line of any not matched impedance can be there is in the high-frequency signal of serious distortion from these.It is multiple parallel brush mistake owing to being connected that serious distortion also may occur in addition.Energy is by slip ring and frequency such as, because of various effect, impedance mismatch, and circuit resonance distributed inductance and electric capacity, dielectric absorption and multiple reflections increase loss.Frequency analog and Interface for digital communication rotate and also use other technologies, as optical fiber interface, and capacitive coupling, the direct transmission of inductance coupling high and electromagnetic radiation, but system adopts these technology relatively costly often.
[summary of the invention]
For solving above deficiency, the invention provides a kind of high-frequency rotary connector, this device effectively solves existing slip ring serious distortion situation when signal transmission, and this apparatus structure simply has very strong practicality simultaneously.
The problem to be solved in the present invention is the signal transmission technology problem in rotary body, and traditional slip ring is serious distortion when signal transmission, provides one easily can produce, economic slip ring system simultaneously.
A kind of high-frequency rotary connector is made up of rotor, stator two parts, and wherein stationary part is made up of axle, stator case tang in stator groove, stator case, stator SAM slot, stator; Rotor portion is made up of axle, rolling jockey, rotor case recess in rotor apical axis, rotor case, rotor SAM card slot, rotor.
Described a kind of high-frequency rotary connector is characterized in that stationary part stator case inside comprises axle in a coaxial stator, in stator, one end of axle is connected with stator SAM slot, in stator, other one end of axle comprises a stator groove, and stator case and rotor cohesive end comprise a stator case tang.
Described a kind of high-frequency rotary connector is characterized in that comprising axle in a coaxial rotor in rotor portion rotor, in rotor, one end of axle is connected with rotor SAM slot, in rotor, other one end of axle comprises a rotor apical axis, this rotor apical axis can slip with stator groove closely, rotor case and stator case cohesive end comprise a rotor case recess, this rotor case recess and the good clamping of stator case.
Described a kind of high-frequency rotary connector is characterized in that rotor portion can corresponding stationary part rotor central axis, and rotor SAM slot can be connected with whirligig by plug wire, and stator SAM slot can be connected with stiff end by plug wire.
Described a kind of high-frequency rotary connector is characterized in that the rotor apical axis of rotor portion is connected coaxial rotation with rotor axis, and rotor apical axis comprises a rolling jockey and stator groove is slidably connected.
A kind of high-frequency rotary connector is slidably connected by stator groove, rotor apical axis and rolling jockey, passes through formed closed connection realization and to run up lower unlikely Signal transmissions distortion phenomenon.
Beneficial effect of the present invention: serious distortion when the signals transmission signal transmission that this device effectively solves, simultaneously simple and reasonable, cost is lower.
For making further to understand characteristic sum technology contents of the present invention, refer to drawings and embodiments of the present invention, however institute's accompanying drawings only for reference with explanation use, the present invention is limited.
