[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the present invention, reference is made to Figure 1 - Figure 7 Shown: A radio frequency coaxial switch, comprising: The switch body 1 has a mounting docking structure 3 fastened to its bottom, which is used to ensure that the internal microstrip transmission line transmits signals on the circuit board through the shielding cover; The contact terminal 4 is installed at the bottom of the mounting docking structure 3 to ensure that the inner conductor 8, the dielectric 9 and the outer conductor 7 can perform signal transmission operations with high performance; A dynamic control component 11 is installed in the internal cavity of the contact terminal 4 and is used to form an adaptive adjustment operation when the contact operation is performed according to the multiple groups of dynamic contact point control components 12 inside the surface of the inner conductor 8; The dynamic contact point regulating component 12 is embedded in the inner conductor 8 and is used to form an effective electrical connection according to the contact operation of the contact points without mutual interference.

[0021] Embodiment 1: In the present invention, according to Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the dynamic contact point control component 12 includes: The directional pitch-adjustable sliding cavity 120, the magnetic particle guiding cavity 121, the flexible superconducting contact point 122 and the magnetic particle guiding tube 123, the directional pitch-adjustable sliding cavity 120 is installed inside the inner conductor 8, the magnetic particle guiding cavity 121 drives the flexible superconducting contact point 122 to form sliding adjustment inside the directional pitch-adjustable sliding cavity 120, the side end of the magnetic particle guiding tube 123 and the magnetic particle guiding cavity 121 are connected, and a micro-ridge brush cavity is installed inside the connecting end of the magnetic particle guiding cavity 121 and the flexible superconducting contact point 122, which is used to brush the aggregated magnetic particles when transporting nano-scale magnetic particles to the flexible superconducting contact point 122, so that the magnetic particles are transported as single particles.

[0022] The other side end of the magnetic particle guide tube 123 is connected to the annular guide distribution tube 124, and the side wall surface of the annular guide distribution tube 124 is connected to the microfluidic guide cavity 129. The side end of the microfluidic guide cavity 129 is connected to the microfluidic guide chip 128. The microfluidic guide chip 128 is composed of micro-channels, valves and mixing chambers. The top of the microfluidic guide chip 128 is connected to the fluid guide control tube 127.

[0023] The top of the fluid guiding regulating tube 127 is connected to the magnetic particle storage chamber 1290. A mixing chamber is arranged inside the magnetic particle storage chamber 1290 to evenly disperse the nano-scale magnetic particles and reduce aggregation. An insulating fluid guiding distributor 126 is installed at the top of the magnetic particle storage chamber 1290. The top of the insulating fluid guiding distributor 126 is connected to the fluid guiding connection terminal 125.

[0024] In a specific solution, before the RF coaxial switch works, the nano-scale magnetic particles in the magnetic particle storage chamber 1290 are initially evenly dispersed in its internal mixing chamber, and the insulating fluid enters the insulating fluid guide distributor 126 through the fluid guide connection end 125. Under the action of the insulating fluid guide distributor 126, the insulating fluid enters the mixing chamber of the magnetic particle storage chamber 1290 at a stable pressure and flow rate, and is fully mixed with the magnetic particles, further ensuring the uniform dispersion of the magnetic particles in the fluid, preventing them from agglomerating, and preparing for subsequent precise guidance. When the RF coaxial switch receives a signal and needs to regulate the contact point, the pressure in the fluid guide regulation tube 127 changes, and begins to drive the mixture with the magnetic particles. The insulating fluid of the microfluidic guide chip 128 flows, and the fluid first enters the microfluidic guide chip 128. In the microfluidic guide chip 128, the flow rate, flow velocity and concentration of the magnetic particles are precisely controlled through the synergistic effect of the microchannel, the valve and the mixing chamber. In cooperation with the pressure sensor, according to the information fed back by the pressure sensor, the valve in the microfluidic guide chip 128 will adjust the opening to control the amount of fluid and magnetic particles entering the microfluidic guide cavity 129. The mixed fluid flowing out of the microfluidic guide cavity 129 enters the annular guide distribution pipe 124, and the annular guide distribution pipe 124 evenly distributes the fluid to each magnetic particle guide pipe 123, and the magnetic particle guide pipe 123 transports the mixed fluid to the magnetic particle guide cavity 121. At the connection end between the particle guide cavity 121 and the flexible superconducting contact point 122, the microridge brush cavity starts to work. When the fluid containing magnetic particles enters the microridge brush cavity, the tiny protrusions or texture structures inside the microridge brush cavity will comb and disperse the magnetic particles that may be gathered, so that the magnetic particles enter the flexible superconducting contact point 122 in the form of single particles. The magnetic particles entering the flexible superconducting contact point 122 respond to the magnetic field generated by the flexible control electromagnetic coil structure 1190 in the dynamic control component 11, so that according to the strength and direction of the magnetic field and the characteristics of the magnetic particles, the magnetic particles will move and distribute inside the flexible superconducting contact point 122, thereby changing the contact pressure, contact area or contact point of the flexible superconducting contact point 122. Distribution state, etc., that is, when the contact pressure needs to be increased to adapt to high-frequency or high-power signals, the magnetic field drives the magnetic particles to gather in a specific area inside the flexible superconducting contact point 122, so that the flexible superconducting contact point 122 expands or deforms, and increases the contact pressure with the inner conductor 8 or other contact parts, so as to optimize the electrical connection performance. During the whole process, the state changes of the contact point, such as contact pressure, contact resistance or magnetic field distribution parameters, are monitored in real time by the pressure sensor and magnetic field control sensor arranged on the inner conductor 8, so that the pressure sensor and the magnetic field control sensor feed back the monitored information to the microprocessor controller, and the microprocessor controller compares and analyzes the preset target parameters and the actual monitoring values. When it is found that the state of the contact point does not meet the expected requirements,The microprocessor controller will adjust the pressure of the fluid delivery control tube 127, the valve opening or magnetic field strength of the microfluidic delivery chip 128, and drive the delivery of magnetic particles and the regulation of the flexible superconducting contact point 122 again until the state of the contact point meets the optimal requirements of signal transmission. The overall contact pressure is automatically adjusted according to the high-frequency signal or the low-frequency signal to reduce the problem of communication signal errors caused by poor contact, which affects the overall operation performance.

[0025] Embodiment 2: In the present invention, according to Figure 3 , Figure 4 and Figure 6 As shown, the dynamic control component 11 includes: The micro high-precision pressure regulating fluid pump 110, the fluid dispenser 111, the ring guide cavity 112 and the secondary fluid guide tube 113, the bottom end of the secondary fluid guide tube 113 and the top end of the fluid guide connection end 125 form a connecting arrangement, the outside of the micro high-precision pressure regulating fluid pump 110 is installed with a protective shell 5 through an airbag cushion installation arrangement, the micro high-precision pressure regulating fluid pump 110 and the fluid dispenser 111 are connected through a catheter, the ring guide cavity 112 is connected with a fluid pressure tube 114, and the micro high-precision pressure regulating fluid pump 110 and the fluid dispenser 111 form a signal connection through a pressure sensor installed inside the inner conductor 8.

[0026] The bottom end of the fluid pressure tube 114 is connected to the first fluid valve tube 116 and the second fluid valve tube 117 respectively. The first fluid valve tube 116 and the second fluid valve tube 117 are both connected through the movable cavity 115. The two side surfaces of the movable cavity 115 are provided with side grooves 119.

[0027] The movable cavity 115 is internally slidably connected with an electromagnetic coil insulating sliding block 1192, and the top and bottom of the electromagnetic coil insulating sliding block 1192 are respectively connected with an upper pressing plate 1193 and a lower pressing plate 1191. The first fluid valve tube 116 pushes the lower pressing plate 1191 to slide upward inside the movable cavity 115 through the delivered pressure fluid.

[0028] The second fluid valve tube 117 pushes the upper pressure plate 1193 to slide downward inside the movable cavity 115 through the delivered pressure fluid, and the interior of the electromagnetic coil insulating sliding block 1192 is provided with a flexible control electromagnetic coil structure 1190, and the flexible control electromagnetic coil structure 1190 and the magnetic field control sensor built into the inner conductor 8 form a signal connection, and the top of the flexible control electromagnetic coil structure 1190 is fastened with a solid block 118, and the solid block 118 drives the top of the flexible control electromagnetic coil structure 1190 to be located at the internal top end of the movable cavity 115 to form a fastened connection.

[0029] In a specific solution, when the above-mentioned RF coaxial switch is operating, when the contact point needs to be regulated according to the feedback from the pressure sensor and the magnetic field control sensor, the micro high-precision pressure regulating fluid pump 110 is started, so that the insulating fluid is pressurized and then transported to the fluid proper amount distributor 111 through the catheter. The fluid proper amount distributor 111 accurately distributes the fluid to the ring guide cavity 112 and the subsequent fluid pressure tube 114 according to the preset parameters or the feedback signal from the pressure sensor inside the inner conductor 8. In this process, the airbag cushion in the protective shell 5 installed outside the micro high-precision pressure regulating fluid pump 110 plays a role in buffering and stabilizing the operation of the pump body, reducing the impact of external vibration and impact on the operation of the RF coaxial switch. Then the fluid pressure tube 114 transports the pressure fluid to the first fluid valve tube 116 and the second fluid valve tube 117 respectively. According to the needs, when the pressure fluid in the first fluid valve tube 116 reaches a certain pressure, it will push The lower pressing plate 1191 in the movable cavity 115 slides upward, or the pressure fluid in the second fluid valve tube 117 pushes the upper pressing plate 1193 to slide downward. Since the electromagnetic coil insulating sliding block 1192 connects the upper pressing plate 1193 and the lower pressing plate 1191, the electromagnetic coil insulating sliding block 1192 moves in the movable cavity 115. During this process, the magnetic field control sensor built into the inner conductor 8 monitors the magnetic field changes around the inner conductor 8 in real time, and transmits the signal to the flexible control electromagnetic coil structure 1190. The flexible control electromagnetic coil structure 1190 adjusts its own current and magnetic field strength according to the signal of the magnetic field control sensor. Among them, magnetic particles will be affected by the magnetic field force in the magnetic field, according to the formula: Rather The magnetic field force is The charge of the particle, is the velocity of the particle, is the magnetic field strength; That is, when the electromagnetic coil insulating sliding block 1192 moves, the magnetic field generated by the flexible control electromagnetic coil structure 1190 will affect the movement and distribution of the magnetic particles in the flexible superconducting contact point 122. That is, when the contact pressure of the flexible superconducting contact point 122 needs to be increased, the flexible control electromagnetic coil structure 1190 is adjusted upward to increase the coil tightness of the flexible control electromagnetic coil structure 1190, thereby generating a stronger magnetic field, causing the magnetic particles to gather in a specific direction inside the flexible superconducting contact point 122, causing the contact point to deform and expand, thereby increasing the contact pressure, thereby increasing the overall signal transmission performance, reducing signal loss and reflection, and improving the reliability and efficiency of the RF coaxial switch in processing signals of different frequencies.

[0030] Embodiment 3: In the present invention, according to Figure 1 and Figure 2As shown, a high-frequency signal detection sensor 2 and a low-frequency signal detection sensor are installed inside the side of the switch body 1, and the high-frequency signal detection sensor 2 and the low-frequency signal detection sensor form a signal connection with the microprocessor controller inside the switch body 1.

[0031] The top of the switch body 1 is provided with a connection terminal 6 , and the bottom of the contact terminal 4 is embedded with a sealing ring 10 .

[0032] In a specific solution, the high-frequency signal detection sensor 2 and the low-frequency signal detection sensor located inside the side of the switch body 1 operate in real time, so that the high-frequency signal detection sensor 2 detects the high-frequency radio frequency signal, and the low-frequency signal detection sensor detects the low-frequency signal, and converts the detected signal information into an electrical signal, and transmits it to the microprocessor controller inside the switch body 1. The microprocessor controller analyzes and identifies these signals according to a preset frequency threshold and signal feature algorithm, determines whether the input signal is a high-frequency signal or a low-frequency signal, and determines whether the signal is in the switch based on the recognition result of the microprocessor controller. The transmission path inside the device body 1, when a high-frequency signal is detected, the microprocessor controller sends instructions to the dynamic control component 11 to make specific adjustments to the dynamic contact point control component 12 to meet the requirements of high-frequency signal transmission, that is, by optimizing the distribution of magnetic particles in the contact point, increasing the contact pressure of the flexible superconducting contact point 122, ensuring that the high-frequency signal can be transmitted through the contact terminal 4 with low loss and high fidelity. For low-frequency signals, the opposite is true. During the long-term use of the RF coaxial switch, the sealing ring 10 can effectively prevent dust, moisture, corrosive gases, etc. from entering the inside of the contact terminal 4.

[0033] The high-frequency signal detection sensor 2, the wiring of the low-frequency signal detection sensor, the miniature high-precision pressure regulating fluid pump 110, the fluid dispenser 111, the flexible control electromagnetic coil structure 1190, the pressure sensor and the magnetic field control sensor in the present invention are common knowledge in the field, and their working principles are already known technologies. The models are selected according to actual use. Therefore, the control method and wiring arrangement of the high-frequency signal detection sensor 2, the wiring of the low-frequency signal detection sensor, the miniature high-precision pressure regulating fluid pump 110, the fluid dispenser 111, the flexible control electromagnetic coil structure 1190, the pressure sensor and the magnetic field control sensor will no longer be explained in detail.
