Description

Technical Field

[0001] The present application relates to the field of microwave oven switches, and in particular to a high-precision driving structure of a radio frequency reed and a driving method thereof. Background Art

[0002] At present, microwave mechanical switch, also known as RF switch, is a device used to control the conversion of microwave signal channels. It plays an important role in microwave test systems and is used for signal routing between instruments and devices under test. Microwave mechanical switches mainly rely on mechanical contact as a switching mechanism to achieve signal switching and routing functions.

[0003] In the related art, the RF reed driving mechanism in the currently common microwave mechanical switch includes a bracket, a movable RF reed and two conductive rods, and the two conductive rods are installed on the bracket at intervals. The movable RF reed is slidably connected to the bracket and arranged opposite to the two conductive rods. When the microwave mechanical switch is in operation, the movable RF reed is slid on the bracket to make the movable RF reed contact with the two conductive rods, or move away from the two conductive rods, thereby energizing or de-energizing the two conductive rods.

[0004] The above-mentioned related technologies have the following defects: when the movable RF reed slides on the bracket, it will produce excess material due to the friction of the movement, and the friction force will also be unstable due to the interference of the excess material, affecting the movement accuracy of the movable RF reed. Summary of the invention

[0005] In order to improve the driving accuracy of a radio frequency reed, the present application provides a high-precision driving structure of a radio frequency reed and a driving method thereof.

[0006] The present application provides a high-precision driving structure and driving method of a radio frequency reed, which adopts the following technical solutions:

[0007] A high-precision driving structure for a radio frequency reed, comprising a frame, a radio frequency switch and a driving mechanism; the radio frequency switch comprises a radio frequency reed element and two conductor rods, the two conductor rods being installed on the frame at intervals; the radio frequency reed element is arranged opposite to the two conductor rods and can move toward the two conductor rods;

[0008] The driving mechanism includes a push rod and a plurality of leaf springs; the plurality of leaf springs are arranged on the frame, and both ends of the leaf springs in the width direction are connected to the frame; one end of the push rod is connected to the plurality of leaf springs, and the other end is connected to the RF reed element, and is also spaced apart from the frame.

[0009] By adopting the above technical solution, when the RF switch is turned on, the push rod is pushed toward the conductor rod, and the leaf spring bulges and deforms toward the conductor rod, so that the RF reed element contacts the two conductor rods, and the deformed leaf spring limits the push rod at this time, so that the two conductor rods are connected through the RF reed element. When the RF switch is turned off, the push rod is pulled in a direction away from the conductor rod, and the leaf spring bulges and deforms in a direction away from the conductor rod, so that the RF reed element contacts away from the two conductor rods, and the deformed leaf spring limits the push rod at this time, so that the connection between the two conductor rods is disconnected. In the present application, the push rod is only connected to the leaf spring, and the RF reed element is only connected to the push rod. The deformation process of the leaf spring is limited by itself, and then the push rod, the RF reed element and the leaf spring, except for the fixed point, do not have contact and friction with other parts to affect the accuracy of the free stroke, thereby improving the driving accuracy of the RF reed.

[0010] Optionally, a plurality of leaf springs are spaced apart and distributed along the length direction of the push rod;

[0011] The leaf spring includes a push rod fixing ring and two side plates, wherein the two side plates are respectively arranged on both sides of the push rod fixing ring in the length direction and are also located on a side of the push rod fixing ring away from the RF leaf spring element;

[0012] The two side plates are movably arranged on the frame, and are both connected to the push rod fixing ring by a first elastic connecting piece;

[0013] The push rod is coaxially fixedly installed in the push rod fixing ring.

[0014] By adopting the above technical solution, several leaf springs are spaced apart in the length direction of the push rod, so that the driving force is more uniform and the movement accuracy of the RF reed is improved. When the RF switch is turned on, the push rod is pushed in the direction of the conductor rod until the push rod fixing ring moves to between the RF reed element and the side plate. At this time, under the elastic force of the first elastic connecting piece, the RF reed element contacts the two conductor rods, so that the two conductor rods are energized. When the RF switch is turned off, the push rod is pulled away from the conductor rod until the push rod fixing ring moves to the side of the side plate away from the RF reed element. At this time, under the elastic force of the first elastic connecting piece, the RF reed element contacts away from the two conductor rods, so that the power is cut off between the two conductor rods.

[0015] Optionally, the two side plates are symmetrically arranged on both sides of the push rod fixing ring in the length direction.

[0016] By adopting the above technical solution and the symmetrical shape structure, when the push rod is subjected to axial force, the center deviation has a self-recovery function. When the force deviates from the axial direction of the push rod, the rebound force on the side where the leaf spring is more deformed is larger, thereby driving the push rod to reset and stabilize. As a result, the push rod fixing ring can maintain balance when subjected to force, avoiding deviation or tilting due to uneven force, thereby improving the stability and reliability of the RF spring element. At the same time, this symmetrical design also helps to improve the overall rigidity of the leaf spring, enhance its stability when subjected to large driving force, and further improve the contact accuracy and response speed between the RF spring and the conductor rod.

[0017] Optionally, the leaf spring further includes two side connecting rings, which are respectively arranged on both sides of the push rod fixing ring in the width direction and are both located on the side of the two side plates away from the push rod fixing ring;

[0018] The two side connecting rings are both installed on the frame, and a second elastic connecting sheet is connected between the two side connecting rings and each side plate.

[0019] By adopting the above technical solution, the leaf spring can more stably drive the push rod closer to or away from the two conductor rods when subjected to force, thereby improving the overall stability and reliability of the driving mechanism. At the same time, the design of the side connecting ring also enhances the structural strength of the entire leaf spring, reduces the risk of deformation caused by external vibration or impact, and further improves the response speed and service life of the RF switch.

[0020] Optionally, the two side connecting rings are symmetrically arranged on both sides of the push rod fixing ring in the width direction.

[0021] By adopting the above technical solution, the connecting rings are symmetrically arranged on both sides of the push rod fixing ring in the width direction, making the entire leaf spring structure more balanced and improving the stability and reliability of the driving mechanism. During the driving process, this symmetrical design can effectively reduce deviation and vibration, ensuring that the RF leaf spring element accurately contacts or separates from the conductor rod, thereby achieving high-precision RF signal control.

[0022] Optionally, the push rod fixing ring, the side connecting ring, the side plate, the first elastic connecting piece and the second elastic connecting piece are integrally formed.

[0023] By adopting the above technical solution, the mechanical strength and stability of the entire drive mechanism are improved, the assembly errors between components are reduced, and the coordination and consistency between components during the driving process are ensured, thereby improving the reliability and service life of the RF switch. At the same time, the one-piece design simplifies the manufacturing process and reduces production costs.

[0024] Optionally, the side connecting ring and the side plate are both detachably connected to the frame.

[0025] By adopting the above technical solution, the assembly and maintenance of the entire drive mechanism are more convenient, and the production efficiency and reliability of the equipment are improved. At the same time, this connection method is also convenient for replacing or adjusting components during actual use, thereby ensuring the performance stability and long-term reliability of the high-precision drive structure of the RF reed.

[0026] Optionally, the conductor rod and the push rod are parallel; the push rod is arranged between the two conductor rods.

[0027] By adopting the above technical solution, the push rod can move accurately in the space between the two conductor rods, thereby ensuring that the RF reed element can accurately contact or separate from the two conductor rods. This layout not only improves the operating accuracy of the RF switch, but also reduces the problem of poor contact caused by position deviation, and enhances the stability and reliability of the system.

[0028] Optionally, the two conductor rods are symmetrically arranged on both sides of the push rod.

[0029] By adopting the above technical solution, the push rod can move more smoothly during movement, avoiding the deviation or jamming caused by asymmetric position, thereby improving the contact accuracy and reliability between the RF reed and the conductor rod. At the same time, the symmetrically arranged conductor rods can also ensure the stability and consistency of RF signal transmission, further improving the performance of the entire RF switch.

[0030] A high-precision driving method for a radio frequency reed, based on the high-precision driving structure for a radio frequency reed described above, comprises the following steps:

[0031] S1, turning on the RF switch, pushing the push rod toward the conductor rod, until the push rod fixing ring moves to between the RF reed element and the side plate, at which time, under the elastic force of the first elastic connecting sheet, the RF reed element contacts the two conductor rods, so that electricity is passed between the two conductor rods;

[0032] S2. Turn off the RF switch and pull the push rod away from the conductor rod until the push rod fixing ring moves to the side of the side plate away from the RF reed element. At this time, under the elastic force of the first elastic connecting piece, the RF reed element moves away from the two conductor rods, thereby cutting off the power between the two conductor rods.

[0033] By adopting the above technical solution, the RF switch can be precisely controlled to ensure that when the RF switch is turned on, the push rod can accurately push the RF reed element to contact the two conductor rods, thereby achieving reliable power supply to the two. When the RF switch is turned off, the push rod can accurately pull the RF reed element away from the two conductor rods to ensure power is cut off between the two. The entire process is ensured by the elastic force of the first elastic connecting piece, which ensures the stability and reliability of the operation and improves the working efficiency and service life of the RF switch.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. In the present application, the push rod is only connected to the leaf spring, and the RF reed element is only connected to the push rod. The deformation process of the leaf spring is limited by itself. Therefore, except for the fixed points, the push rod, the RF reed element and the leaf spring do not have any contact and friction with other parts that affect the free stroke accuracy, thereby improving the driving accuracy of the RF reed.

[0036] 2. In the present application, by evenly distributing a number of leaf springs in the length direction of the push rod, the force can be transmitted more evenly when subjected to external force, so that the push rod can more smoothly approach or move away from the conductor rod, thereby improving the driving accuracy and stability of the RF leaf spring.

[0037] 3. In the present application, the structural design of the leaf spring enables the push rod to effectively transmit and disperse stress when subjected to force, thereby avoiding fatigue failure caused by local stress concentration and extending the service life of the RF leaf spring drive structure.

[0038] 4. In the present application, the direct connection between the push rod and the RF reed element, as well as the elastic support of the leaf spring, ensure that the RF reed element can respond quickly and accurately reach the target position during movement, thereby improving the response speed and reliability of the RF switch.

DETAILED DESCRIPTION

[0050] The following is combined with Figure 1-8 This application is described in further detail.

[0051] Reference Figure 1 and Figure 2, which is a common microwave mechanical switch, the RF reed drive mechanism 1 includes a bracket 11, two conductive rods 12, two guide rods 13, a movable RF reed 14, a guide tube 15, a drive rod 16 and a reset spring 17. The two conductive rods 12 are parallel and symmetrically mounted on the bracket 11, and the end of the guide rod 13 away from the bracket 11 is provided with a connection contact 121. The guide rod 13 is arranged between the two conductive rods 12 and is parallel to the conductive rods 12; the movable RF reed 14 is arranged opposite to the two contacts and is slidably connected to the two guide rods 13; the guide tube 15 is installed on the side of the movable RF reed 14 away from the contacts along the length direction of the guide rod 13 and is connected to the bracket 11. The drive rod 16 is coaxially arranged in the guide tube 15 and is slidably connected to the guide tube 15. The reset spring 17 is sleeved on the drive rod 16, and one end is connected to the drive rod 16, and the other end is connected to the bracket 11. When the microwave mechanical switch is started, the driving rod 16 is pushed toward the contact direction, and the movable RF reed 14 contacts the two connection contacts 121, so that the two conductive rods 12 are connected and energized via the movable RF reed 14. When the microwave mechanical switch is closed, the driving rod 16 is released, and under the action of the reset elastic force of the reset spring 17, the driving rod 16 is reset, and the movable RF reed 14 is away from the two connection contacts 121, so that the connection between the two conductive rods 12 is disconnected.

[0052] However, when the movable RF reed 14 slides on the guide rod 13 and when the driving rod 16 slides in the guide tube 15, excess material will be generated due to the friction of the movement. At the same time, the friction force will be unstable due to the interference of the excess material, affecting the movement stability of the movable RF reed 14, and further affecting the consistent repeatability of the contact state between the movable RF reed 14 and the two connecting contacts 121.

[0053] In order to solve this problem, the embodiments of the present application disclose a high-precision driving structure of a radio frequency reed and a driving method thereof.

[0054] Reference Figure 3 , Figure 4 and Figure 5, a high-precision driving structure of a radio frequency reed, comprising a frame 2, a radio frequency switch 3 and a driving mechanism 4. The radio frequency switch 3 comprises a radio frequency reed element 33 and two conductor rods 31, the two conductor rods 31 are installed on the frame 2 at intervals, the two conductor rods 31 are parallel and symmetrical, and a conductive contact 32 is provided at one end of the conductor rod 31 away from the frame 2. The radio frequency reed element 33 is arranged opposite to the two conductor rods 31, and can move toward the two conductor rods 31, and is used to contact the two conductive contacts 32. The driving mechanism 4 comprises a push rod 41 and a plurality of leaf springs 42. The plurality of leaf springs 42 are distributed at intervals in the length direction of the push rod 41, so that the driving force is more uniform, and the movement accuracy of the radio frequency reed is improved. The plurality of leaf springs 42 are all installed on the frame 2, and the two ends of the leaf springs 42 in the width direction are connected to the frame 2. One end of the push rod 41 is connected to the plurality of leaf springs 42, and the other end is connected to the radio frequency reed element 33, and is also arranged at intervals with the frame 2. The conductor rod 31 and the push rod 41 are parallel. The push rod 41 is disposed between the two conductor rods 31 , and the two conductor rods 31 are symmetrically disposed on both sides of the push rod 41 , thereby ensuring that the RF reed element 33 can accurately contact or separate from the two conductor rods 31 .

[0055] Reference Figure 3 , Figure 4 and Figure 5 In the embodiment of the present application, the number of leaf springs 42 is set according to actual needs and can be one or more. When the RF switch 3 is turned on, the push rod 41 is pushed toward the conductor rod 31, and the leaf spring 42 bulges and deforms toward the conductor rod 31, so that the RF reed element 33 contacts the two conductor rods 31, and the deformed leaf spring 42 limits the push rod 41 at this time, so that the two conductor rods 31 are connected through the RF reed element 33. When the RF switch 3 is turned off, the push rod 41 is pulled in a direction away from the conductor rod 31, and the leaf spring 42 bulges and deforms in a direction away from the conductor rod 31, so that the RF reed element 33 contacts the two conductor rods 31, and the deformed leaf spring 42 limits the push rod 41 at this time, so that the connection between the two conductor rods 31 is disconnected. The two conductor rods 31 are arranged parallel and symmetrically on both sides of the push rod 41, so that the push rod 41 can be more stable during the movement, avoiding the offset or jamming caused by the asymmetric position, thereby improving the contact accuracy and reliability between the RF reed and the conductor rod 31. In the present application, the push rod 41 is only connected to the leaf spring 42, and the RF reed element 33 is only connected to the push rod 41. The deformation process of the leaf spring 42 is limited by itself, and thus, except for the fixed points, the push rod 41, the RF reed element 33 and the leaf spring 42 do not have any contact and friction with other parts that affect the free stroke accuracy, thereby improving the driving accuracy of the RF reed.

[0056] Reference Figure 5The leaf spring 42 includes a push rod fixing ring 421 and two side plates 423. The two side plates 423 are respectively arranged on both sides of the push rod fixing ring 421 in the length direction and are also located on the side of the push rod fixing ring 421 away from the RF leaf spring element 33. Both side plates 423 are movably arranged on the frame 2, and both are connected to the push rod fixing ring 421 by a first elastic connecting piece 424. The push rod 41 is coaxially fixedly installed in the push rod fixing ring 421.

[0057] Reference Figure 6 A first elastic connecting piece 424 is connected between the two side plates 423 and the push rod fixing ring 421, and the two first elastic connecting pieces 424 are symmetrically arranged on both sides of the push rod fixing ring 421. Figure 7 , two first elastic connecting pieces 424 are connected between the two side plates 423 and the push rod fixing ring 421. When the first elastic connecting piece 424 is a rectangular plate, the two first elastic connecting pieces 424 are arranged parallel and symmetrically at one end of the push rod fixing ring 421 in the length direction. Figure 8 , when two first elastic connecting pieces 424 are connected between the two side plates 423 and the push rod fixing ring 421, when the first elastic connecting piece 424 is a trapezoidal plate, the two first elastic connecting pieces 424 are symmetrically arranged at one end in the length direction of the push rod fixing ring 421. In other embodiments, the first elastic connecting piece 424 may also be in other long strip shapes, but when the first elastic connecting piece 424 is arranged, the symmetry of the first elastic connecting piece 424 in the length direction and the width direction of the push rod fixing ring 421 must be ensured, so as to ensure that the push rod fixing ring 421 is not easily deflected when subjected to force.

[0058] Reference Figure 3 , Figure 4 and Figure 5 In the embodiment of the present application, when the RF switch 3 is turned on, the push rod 41 is pushed toward the conductor rod 31 until the push rod fixing ring 421 moves between the RF reed element 33 and the side plate 423. At this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 contacts the two conductor rods 31, so that the two conductor rods 31 are energized. When the RF switch 3 is turned off, the push rod 41 is pulled away from the conductor rod 31 until the push rod fixing ring 421 moves to the side of the side plate 423 away from the RF reed element 33. At this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 contacts away from the two conductor rods 31, so that the two conductor rods 31 are deenergized.

[0059] Reference Figure 3 , Figure 4 and Figure 5, the two side plates 423 are symmetrically arranged on both sides of the length direction of the push rod fixing ring 421. In the embodiment of the present application, the symmetrical outer shape structure, when the push rod 41 is subjected to axial force, the center deviation has a self-recovery function. When the force deviates from the axial direction of the push rod 41, the side of the leaf spring 42 with a larger deformation has a larger rebound force, thereby driving the push rod 41 to reset and stabilize. In this way, the push rod fixing ring 421 can maintain balance when subjected to force, avoiding deviation or tilting caused by uneven force, thereby improving the stability and reliability of the RF reed element 33. At the same time, this symmetrical design also helps to improve the overall rigidity of the leaf spring 42, enhance its stability when subjected to a large driving force, and further improve the contact accuracy and response speed between the RF reed and the conductor rod 31.

[0060] Reference Figure 3 , Figure 4 and Figure 5 , the leaf spring 42 also includes two side connecting rings 422, which are respectively arranged on both sides of the push rod fixing ring 421 in the width direction, and are both located on the side of the two side plates 423 away from the push rod fixing ring 421. The two side connecting rings 422 are both installed on the frame 2, and a second elastic connecting piece 425 is connected between the two side connecting rings 422 and each side plate 423. In the embodiment of the present application, when the leaf spring 42 is subjected to force, it can more stably drive the push rod 41 to approach or move away from the two conductor rods 31, thereby improving the overall stability and reliability of the driving mechanism 4. At the same time, the design of the side connecting ring 422 also enhances the structural strength of the entire leaf spring 42, reduces the risk of deformation caused by external vibration or impact, and further improves the response speed and service life of the RF switch 3.

[0061] Reference Figure 3 , Figure 4 and Figure 5 , the two side connecting rings 422 are symmetrically arranged on both sides of the width direction of the push rod fixing ring 421. In the embodiment of the present application, the connecting rings are symmetrically arranged on both sides of the width direction of the push rod fixing ring 421, so that the entire leaf spring 42 structure is more balanced, and the stability and reliability of the driving mechanism 4 are improved. During the driving process, this symmetrical design can effectively reduce the deviation and vibration, and ensure that the RF leaf spring element 33 accurately contacts or separates from the conductor rod 31, thereby achieving high-precision RF signal control.

[0062] Reference Figure 3 , Figure 4 and Figure 5, the push rod fixing ring 421, the side connecting ring 422, the side plate 423, the first elastic connecting piece 424 and the second elastic connecting piece 425 are integrally formed. In the embodiment of the present application, the mechanical strength and stability of the entire driving mechanism 4 are improved, the assembly error between components is reduced, and the coordination and consistency between the components during the driving process are ensured, thereby improving the reliability and service life of the RF switch 3. At the same time, the one-piece design simplifies the manufacturing process and reduces the production cost.

[0063] Reference Figure 3 , Figure 4 and Figure 5 , the side connecting ring 422 and the side plate 423 are both detachably connected to the frame 2. In the embodiment of the present application, the assembly and maintenance of the entire drive mechanism 4 are more convenient, and the production efficiency and reliability of the equipment are improved. At the same time, this connection method is also convenient for replacing or adjusting components during actual use, thereby ensuring the performance stability and long-term reliability of the high-precision drive structure of the RF reed.

[0064] Reference Figure 3 , Figure 4 and Figure 5 A high-precision driving method for a radio frequency reed is provided, based on the above-mentioned high-precision driving structure for a radio frequency reed, and comprises the following steps:

[0065] S1, turn on the RF switch 3, push the push rod 41 in the direction of the conductor rod 31, until the push rod fixing ring 421 moves to between the RF reed element 33 and the side plate 423, at this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 contacts the two conductor rods 31, so that the two conductor rods 31 are energized;

[0066] S2, turn off the RF switch 3, pull the push rod 41 in the direction away from the conductor rod 31, until the push rod fixing ring 421 moves to the side of the side plate 423 away from the RF reed element 33, at this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 is away from the two conductor rods 31, so that the power between the two conductor rods 31 is cut off.

[0067] In the embodiment of the present application, the radio frequency switch 3 can be precisely controlled to ensure that when the radio frequency switch 3 is turned on, the push rod 41 can accurately push the radio frequency reed element 33 to contact the two conductor rods 31, thereby achieving reliable power supply to both. When the radio frequency switch 3 is turned off, the push rod 41 can accurately pull the radio frequency reed element 33 away from the two conductor rods 31 to ensure power is cut off between the two. The whole process is ensured by the elastic force of the first elastic connecting piece 424, which ensures the stability and reliability of the operation and improves the working efficiency and service life of the radio frequency switch 3.

[0068] The implementation principle of a high-precision driving structure and driving method of a radio frequency reed in the embodiment of the present application is as follows:

[0069] Turn on the RF switch 3 and push the push rod 41 toward the conductor rod 31 until the push rod fixing ring 421 moves between the RF reed element 33 and the side plate 423. At this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 contacts the two conductor rods 31, so that electricity is passed between the two conductor rods 31.

[0070] Turn off the RF switch 3 and pull the push rod 41 away from the conductor rod 31 until the push rod fixing ring 421 moves to the side of the side plate 423 away from the RF reed element 33. At this time, under the elastic force of the first elastic connecting piece 424, the RF reed element 33 moves away from the two conductor rods 31, so that the power between the two conductor rods 31 is cut off.
