Description

Technical Field

[0001] The present application relates to the technical field of microwave switches, and in particular to a microwave T-type port layout switch. Background Art

[0002] Microwave switch, also known as RF switch, has a wide range of uses in RF / microwave systems, such as time multiplexer, time division channel selection, pulse modulation, transceiver switch, beam adjustment, etc. RF switch is usually used in automated control circuits. RF switch is actually an "automatic switch" that uses a small current to control a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] At present, the existing RF switch mainly includes a switch mechanism and a relay mechanism, wherein the switch mechanism includes a plurality of terminals, and a conductive sheet is provided between the two corresponding terminals that need to be connected, and a push rod is provided on the conductive sheet. When the connection mechanism and the relay structure are installed, the push rod pushes the conductive sheet to move under the drive of the electromagnetic component inside the relay mechanism, so that the conductive sheet has two states. The first state: the two ends of the conductive sheet are respectively overlapped with the corresponding terminals, at this time the two terminals are conductive, and a signal path between the two terminals can be established; the second state: the two ends of the conductive sheet are separated from the corresponding terminals, at this time the signal path between the two terminals is disconnected.

[0004] The existing terminals are all located on the same side of the RF switch, such as three terminals are often arranged side by side on the same side of the RF switch. This means that when the RF switch is used, several connectors are plugged into and matched with corresponding terminals. At this time, several connectors are all located on the same side of the RF switch. Due to the influence of the connectors, the distance between two adjacent terminals has a minimum value limit, which leads to a larger volume of the RF switch. Summary of the invention

[0005] The present application provides a microwave T-type port layout switch, the purpose of which is to reduce the minimum limit of the distance between adjacent terminals, thereby further reducing the volume of the microwave switch.

[0006] The present application provides a microwave T-type port layout switch adopting the following technical solution: A microwave T-port layout switch comprises a shell, wherein a first terminal is arranged at one end of the shell in the length direction, a second terminal is arranged at the other end, a third terminal is arranged at one side in the width direction of the shell, the first terminal and the second terminal are arranged coaxially, and the axial direction of the third terminal is arranged perpendicular to the axial direction of the first terminal; a conductive sheet is arranged between the first terminal and the third terminal and between the second terminal and the third terminal, the conductive sheet is located in the shell, a push rod is arranged on the conductive sheet, and the push rod and the conductive sheet are both slidably connected to the inner side wall of the shell along the axial direction of the push rod, and the push rod is used to drive the conductive sheet to overlap with the third terminal and the corresponding first terminal or second terminal.

[0007] By adopting the above technical solution, the shell, the first terminal, the second terminal, the third terminal, the conductive sheet and the push rod are arranged in coordination, and the first terminal, the second terminal and the third terminal can all be connected to the connector to realize the input or output of microwave signals. The coordinated arrangement of the conductive sheet and the push rod can overlap one end of the conductive sheet with the third terminal, and overlap the other end with the corresponding first terminal or second terminal. At this time, a signal path between the third terminal and the corresponding first terminal or second terminal can be established to realize the transmission of microwave signals. Therefore, after the relay mechanism is installed on the microwave switch of the present application, the connection between the electromagnetic component inside the relay mechanism and the push rod is established. At this time, the corresponding conductive sheet movement can be automatically controlled by the relay mechanism, and then the signal path between the first terminal and the third terminal or the signal path between the second terminal and the third terminal can be freely established or disconnected. This can meet the function of the microwave T-type port layout switch.

[0008] On this basis, the matching arrangement of the housing, the first terminal, the second terminal and the third terminal enables the terminal layout on the microwave switch to be changed from a side-by-side layout of the three terminals on the same side to a T-shaped layout of the three terminals on different sides. With such a change in the layout, when the first terminal, the second terminal and the third terminal are all plugged into connectors, there will be no interference between the connectors, and thus there is no minimum value restriction on the distance between any two adjacent terminals among the first terminal, the second terminal and the third terminal, thereby significantly reducing the distance between two adjacent terminals and significantly reducing the volume of the entire microwave switch.

[0009] Optionally, a first guide post is coaxially arranged in the first terminal, a second guide post is coaxially arranged in the second terminal, and a third guide post is coaxially arranged in the third terminal, and the first guide post, the second guide post and the third guide post all extend into the outer shell; a first lap joint surface is arranged on the side of the first guide post facing the corresponding conductive sheet, a second lap joint surface is arranged on the side of the second guide post facing the corresponding conductive sheet, and a third lap joint surface is arranged on the side of the third guide post facing the conductive sheet, and the first lap joint surface, the second lap joint surface and the third lap joint surface are all arranged parallel to the conductive sheet; the push rod is used to drive the conductive sheet to overlap with the third lap joint surface and the corresponding first lap joint surface or the corresponding second lap joint surface.

[0010] By adopting the above technical solution, firstly, the setting of the first guide pillar, the second guide pillar and the third guide pillar is used to realize the internal and external signal transmission of the microwave switch, and realize the connection of the corresponding first terminal, the second terminal and the third terminal with the external signal line and the connection of the internal conductive sheet.

[0011] Secondly, the first overlapping surface, the second overlapping surface and the third overlapping surface are arranged in coordination. When the conductive sheet overlaps with the third guide column and the corresponding first guide column or second guide column, the conductive sheet will contact the third overlapping surface and the corresponding first overlapping surface or second overlapping surface, which can increase the overlapping area and thereby improve the stability and reliability of signal transmission.

[0012] Optionally, the first overlapping surface, the second overlapping surface and the third overlapping surface are all arranged flush with each other.

[0013] By adopting the above technical solution, the first overlapping surface, the second overlapping surface and the third overlapping surface are all arranged flush. This design simplifies the structure of the first guide pillar, the second guide pillar and the third guide pillar, making the overlapping of the conductive sheet and the third guide pillar and the corresponding first guide pillar or the corresponding second guide pillar more uniform and precise, which helps to improve the quality of signal transmission and reduce contact resistance.

[0014] Optionally, a side of the first overlapping surface away from the second guide pillar is spaced apart from a side of the corresponding conductive sheet away from the second guide pillar; a side of the second overlapping surface away from the first guide pillar is spaced apart from a side of the corresponding conductive sheet away from the first guide pillar.

[0015] By adopting the above technical solution, the side of the first overlapping surface away from the second guide post is spaced apart from the side of the corresponding conductive sheet away from the second guide post; the side of the second overlapping surface away from the first guide post is spaced apart from the side of the corresponding conductive sheet away from the first guide post. This design provides sufficient assembly space to ensure that the installed conductive sheet can overlap with the corresponding first overlapping surface or the corresponding second overlapping surface.

[0016] Optionally, the first guide column has chamfers or rounded corners at the end surface located inside the shell; the second guide column has chamfers or rounded corners at the end surface located inside the shell; the third guide column has chamfers or rounded corners at the end surface located inside the shell.

[0017] By adopting the above technical solution, the end faces of the first guide post, the second guide post and the third guide post are chamfered or rounded, which can optimize the structure of the first guide post, the second guide post and the third guide post, facilitate the installation of the first guide post, the second guide post and the third guide post, and reduce unnecessary deformation and wear during the installation process, thereby ensuring the quality of signal transmission.

[0018] Optionally, the conductive sheet is rectangular, and first compensating chamfers are provided at two corners of the conductive sheet away from the third guide pillar along its length direction.

[0019] By adopting the above technical solution, the setting of the first compensating chamfer helps to reduce the reflection and scattering of the signal at the corner, thereby reducing signal loss and improving the integrity of signal transmission, thereby improving the signal transmission quality between the conductive sheet and the corresponding first guide post or second guide post.

[0020] Optionally, the diameter of the first guide pillar and the diameter of the second guide pillar are both smaller than the width of the conductive sheet; the width of the conductive sheet along its own length direction on a side away from the third guide pillar is smaller than the corresponding diameter of the first guide pillar or the corresponding diameter of the second guide pillar.

[0021] By adopting the above technical solution, the diameters of the first guide post and the second guide post are both smaller than the width of the conductive sheet. This design can ensure good contact between the conductive sheet and the corresponding first guide post and the corresponding second guide post, which helps to provide sufficient contact area and optimize the signal transmission efficiency. The width of the conductive sheet along its own length direction on the side away from the third guide post is smaller than the diameter of the corresponding first guide post or the second guide post. This design makes the conductive sheet more stable when overlapping with the corresponding first overlap surface or the second overlap surface, reducing the possibility of poor contact. Therefore, such a structural setting is conducive to improving the signal transmission efficiency and transmission stability between the conductive sheet and the corresponding first guide post or the corresponding second guide post.

[0022] Optionally, the conductive sheet is provided with a second compensating chamfer at a corner along its length direction toward the third guide pillar, and the second compensating chamfer is provided at a corner of the conductive sheet away from the third terminal along the width direction of the conductive sheet.

[0023] By adopting the above technical solution, the second compensating chamfer is set to further reduce the reflection and scattering of the signal at the corner of the conductive sheet, improve the signal transmission efficiency and reduce the signal loss, thereby improving the signal transmission quality between the conductive sheet and the third guide post.

[0024] Optionally, a guide member is arranged between the conductive sheet and the outer shell, and the guide member includes a guide column, and the axial direction of the guide column is arranged parallel to the axial direction of the push rod; a guide hole is opened on the conductive sheet, one end of the guide column is connected to the inner wall of the outer shell, and the other end is plugged into the guide hole, and the guide column is slidably connected to the inner wall of the guide hole along its own axial direction.

[0025] By adopting the above technical solution, the guide member ensures that the conductive sheet can move smoothly along the predetermined path under the drive of the push rod through the matching arrangement of the guide column and the guide hole, reduces friction and deviation during movement, and improves the accuracy and reliability of the microwave switch.

[0026] Optionally, two guide members are provided on each of the conductive sheets, the two guide members are spaced apart along the length direction of the conductive sheet, and the push rod is located between the corresponding two guide members.

[0027] By adopting the above technical solution, two guide members are provided on each conductive sheet, and the layout of the two guide members can provide better support and guidance, ensuring the stability of the conductive sheet during movement, thereby improving the reliability of signal transmission.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0038] A microwave T-type port layout switch, referring to Figure 1 , including a housing 1, which is in the shape of a long strip. A first terminal 2 is provided at one end of the housing 1 in the length direction, and a second terminal 3 is provided at the other end. The first terminal 2 is axially arranged along the length direction of the housing 1, and the first terminal 2 and the second terminal 3 are coaxially arranged, and the first terminal 2 and the second terminal 3 are both connected to the housing 1. A third terminal 4 is provided at one side in the width direction of the housing 1, and the third terminal 4 is axially arranged perpendicular to the length direction of the housing 1, and one axial end of the third terminal 4 is connected to the housing 1, and the third terminal 4 is located in the middle of the housing 1 along the length direction of the housing 1.

[0039] The matching arrangement of the housing 1, the first terminal 2, the second terminal 3 and the third terminal 4 enables the three terminals to be arranged in a T-shaped manner instead of being arranged side by side on the same side of the housing 1. With such a layout, when the first terminal 2, the second terminal 3 and the third terminal 4 are all plugged into connectors, there will be no interference between the connectors, which means that there is no minimum value limit for the distance between any two adjacent terminals among the three terminals, thereby significantly reducing the distance between two adjacent terminals, and further significantly reducing the volume of the entire microwave switch.

[0040] Reference Figure 1 and Figure 2A transmission cavity 11 is formed in the housing 1, a first guide post 21 is coaxially arranged in the first terminal 2, and one axial end of the first guide post 21 extends into the transmission cavity 11. A second guide post 31 is coaxially arranged in the second terminal 3, and one axial end of the second guide post 31 extends into the transmission cavity 11. A third guide post 41 is coaxially arranged in the third terminal 4, and one axial end of the third guide post 41 extends into the transmission cavity 11.

[0041] Reference Figure 2 and Figure 3 A conductive sheet 5 is disposed between the first guide post 21 and the third guide post 41 and between the second guide post 31 and the third guide post 41. The conductive sheet 5 is located in the transmission cavity 11. The length direction of the conductive sheet 5 is disposed along the length direction of the housing 1. Two conductive sheets 5 are disposed at intervals along the length direction of the housing 1. A push rod 6 is disposed on the conductive sheet 5. The axial direction of the push rod 6 is perpendicular to the axial direction of the first guide post 21 and the axial direction of the third guide post 41. One axial end of the push rod 6 is connected to the conductive sheet 5, and the other end is slidably connected to the corresponding inner side wall of the housing 1 along its own axial direction. The conductive sheet 5 is also slidably connected to the inner side wall of the housing 1 along the corresponding axial direction of the push rod 6.

[0042] When the push rod 6 pushes the corresponding conductive sheet 5 to move toward the third guide post 41, one end of the conductive sheet 5 can overlap with the third guide post 41, and the other end can overlap with the corresponding first guide post 21 or the corresponding second guide post 31, and at this time, a signal path is established between the third terminal 4 and the corresponding first terminal 2 or the corresponding second terminal 3. On the contrary, when the push rod 6 pushes the corresponding conductive sheet 5 to move away from the third guide post 41, one end of the conductive sheet 5 can be separated from the corresponding third guide post 41, and the other end can be separated from the corresponding first guide post 21 or the corresponding second guide post 31, and at this time, the signal path between the third terminal 4 and the corresponding first terminal 2 or the corresponding second terminal 3 is disconnected.

[0043] Reference Figure 2 and Figure 3 The inner wall of the transmission cavity 11 is penetrated with a push hole 61, which is plugged with the push rod 6, and the push rod 6 is slidably connected with the inner wall of the push hole 61 along its own axial direction. The setting of the push hole 61 realizes the installation of the push rod 6. At the same time, since the push hole 61 penetrates the housing 1, after the relay mechanism is installed on the microwave switch of the present application, the existence of the push hole 61 facilitates the establishment of the connection between the electromagnetic component inside the relay mechanism and the push rod 6, thereby realizing the automatic control of the conductive sheet 5.

[0044] Reference Figure 2 and Figure 3 Two guide members 7 are arranged between each conductive sheet 5 and the inner wall of the transmission cavity 11 .

The arrangement of the first overlapping surface 22, the second overlapping surface 32 and the third overlapping surface 42 can increase the contact area between the first guide pillar 21, the second guide pillar 31 and the third guide pillar 41 and the corresponding conductive sheet 5, thereby improving the stability of the connection and the stability of the signal transmission.
