[0001] The present application relates to the technical field of microwave port matrix switches, and particularly to a microwave port 2x2 matrix switch. Background Art

[0002] Currently, in some test scenarios, it is often necessary to use a microwave port matrix switch to meet different requirements for switch switching in the test.

[0003] A microwave port matrix switch is a device that switches signals in a microwave signal path and is widely used in microwave radio frequency fields such as radar, electronic countermeasure, and communication systems. This switch usually consists of multiple microwave switch elements and can realize flexible switching of signals between different ports.

[0004] The technical specifications of a microwave port matrix switch include but are not limited to operating frequency, number of input and output ports, isolation, insertion loss, port standing wave, anti-burning power, impedance, control interface, etc. For example, the operating frequency range of the HXKGZH2581G type programmable microwave switch matrix is 0.7~3 GHz, it has 16 input ports and 128 output ports, the isolation between output ports is greater than or equal to 80 dB, the insertion loss does not exceed 10 dB, the port standing wave is less than or equal to 1.8, the anti-burning power is 1 W for continuous wave, the delay consistency of each group of channels is less than or equal to 0.5 ns, the impedance is 50 Ω, the input interface includes SMA-K and N-K types, and the control interface includes RJ45 and RS232.

[0005] However, most of the above-mentioned and existing matrix switches have problems such as large volume and large loss, so there is an urgent need for a microwave port matrix switch with a smaller volume and smaller loss to meet the current high-performance requirements for microwave port matrix switches. Summary of the Invention

[0006] The present application provides a microwave port 2x2 matrix switch, which can solve the problems of large volume, long transmission path, and large loss of existing microwave port matrix switches.

[0007] The technical solution of the present application is as follows: A microwave port 2x2 matrix switch includes:

[0008] A main body housing with a hollow interior, a first microwave port and a second microwave port are respectively arranged on the left and right sides of the upper end of the main body housing, and a third microwave port and a fourth microwave port are respectively arranged on the left and right sides of the lower end of the switch main body;

[0009] A first conductor assembly and a second conductor assembly, and two groups of first conductor assemblies and second conductor assemblies are respectively arranged inside the upper and lower ends of the main body housing;

[0010] A coaxial transmission component, which is arranged inside the main body housing and located between the first conductor component and the second conductor component. The upper end of the coaxial transmission component is selectively connected to the first microwave port or the second microwave port through the first conductor component, and the lower end of the coaxial transmission component is selectively connected to the third microwave port or the fourth microwave port through the second conductor component;

[0011] A driving member, which is arranged on the front side or the rear side of the main body housing and is used to drive the first conductor component and the second conductor component to move in the front-rear direction, so that the first conductor component is selectively connected to the first microwave port or the second microwave port and;

[0012] The second conductor component is selectively connected to the third microwave port or the fourth microwave port.

[0013] By adopting the above scheme, four ports are integrated together, and a coaxial transmission line is arranged inside to form a 2x2 rectangular switch layout. When two of the ports are connected, compared with the existing technical means of using an external coaxial transmission line for connection, the transmission distance between the two ports can be effectively shortened, thereby reducing the loss.

[0014] In one embodiment of the present application, the first microwave port, the second microwave port, the third microwave port, and the fourth microwave port are horizontally arranged on the main body housing or;

[0015] The first microwave port, the second microwave port, the third microwave port, and the fourth microwave port are vertically arranged on the main body housing.

[0016] By adopting the above technical scheme, without affecting the 2x2 rectangular switch layout, by changing the orientation of the ports, the device can be customized according to different working conditions and usage space environments, so that the device can meet the working requirements of input and output in the same direction or in the opposite direction.

[0017] In one embodiment of the present application, corresponding first microwave reeds, second microwave reeds, third microwave reeds, and fourth microwave reeds are respectively arranged at one ends of the first microwave port, the second microwave port, the third microwave port, and the fourth microwave port. First cut planes are arranged at one ends of the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed close to the coaxial transmission component.

[0018] By adopting the above scheme, when the first conductor component and the second conductor component are respectively connected to the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed, the first cut plane can make the connection between the first conductor component and the second conductor component more stable and ensure good electrical performance during contact.

[0019] In one embodiment of the present application, the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed are all chamfered or rounded.

[0020] By adopting the above solution, since the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed are distributed up and down, an electric field similar to a rectangle can be formed. After chamfering or rounding the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed, the distribution of the electric field intensity at the sharp edges of the first microwave reed, the second microwave reed, the third microwave reed, and the fourth microwave reed is also optimized, thereby providing a more uniform and stable electric field.

[0021] In one embodiment of the present application, the first conductor assembly includes:

[0022] A first connecting conductor that moves in the front-rear direction to connect or disconnect one end to the first microwave reed and the other end to the upper end of the coaxial transmission assembly;

[0023] A second connecting conductor that moves in the front-rear direction to connect or disconnect one end to the second microwave reed and the other end to the upper end of the coaxial transmission assembly;

[0024] The second conductor assembly includes:

[0025] A third connecting conductor that moves in the front-rear direction to connect or disconnect one end to the third microwave reed and the other end to the lower end of the coaxial transmission assembly;

[0026] A fourth connecting conductor that moves in the front-rear direction to connect or disconnect one end to the fourth microwave reed and the other end to the lower end of the coaxial transmission assembly.

[0027] By adopting the above solution, by respectively providing four groups of connecting conductors and respectively using them to control the on-off between the four ports of the device and the coaxial transmission line, the device can input from the first microwave port, pass through the coaxial transmission assembly, and then output reversely from the third microwave port, or output in the same direction from the fourth microwave port. Similarly, the device can also input from the second microwave port, pass through the coaxial transmission assembly, and then output in the same direction from the third microwave port, or output reversely from the fourth microwave port.

[0028] In one embodiment of the present application, it further includes a driving housing provided on the front side or the rear side of the main body housing. The number of driving members is four groups, and they are all provided on the driving housing;

[0029] Each group of the driving members includes:

[0030] A driving motor, which is arranged in the front-rear direction and assembled on the driving housing;

[0031] A pushing member, which is arranged in the front-rear direction, and one end of the pushing member is connected to the driving shaft of the driving motor;

[0032] A connecting rod, one end of which is fixedly connected to the other end of the pushing member;

[0033] Four groups of the driving members are respectively connected to the first connecting conductor, the second connecting conductor, the third connecting conductor and the fourth connecting conductor through the connecting rod in a one-to-one correspondence.

[0034] By adopting the above technical solutions, the driving assembly is arranged on the front side or the rear side of the main body housing, and the first conductor assembly and the second conductor assembly are controlled to move back and forth perpendicular to the sitting plane of the main body housing, which reduces the occupied space area of the whole device to a certain extent, so that the whole device can be made more portable.

[0035] In one embodiment of the present application, the coaxial transmission assembly includes;

[0036] An outer conductor, which is arranged in the main body housing in the up-down direction;

[0037] An insulating layer, which is coaxially arranged inside the outer conductor;

[0038] An inner conductor, which is coaxially arranged inside the insulating layer, and the upper and lower ends of the inner conductor respectively extend to the front side or the rear side of the first conductor assembly and the second conductor assembly, and second cut planes are respectively arranged on the front side or the rear side of the upper and lower ends of the inner conductor.

[0039] By adopting the above technical solutions, second cut planes are arranged on the inner conductor, which avoids the problem that when the columnar inner conductor is electrically connected to the conductor assembly, the conductor assembly contacts the arc surface of the inner conductor, resulting in poor electrical performance, and improves the connection stability.

[0040] In one embodiment of the present application, key grooves extending axially are annularly distributed outside the inner conductor.

[0041] By adopting the above solutions, by arranging key grooves outside the inner conductor, when it is assembled inside the insulating layer, an interference fit can be achieved, thereby improving the torsional resistance of the inner conductor.

[0042] In one embodiment of the present application, a guide rod arranged in the front-rear direction is further included, and the guide rod is assembled below the first conductor assembly and the second conductor assembly, and is used to support the first conductor assembly and the second conductor assembly, and enable the first conductor assembly and the second conductor assembly to slide on the guide rod.

[0043] By adopting the above technical solution, the guiding rod is used to support the first conductor assembly and the second conductor assembly, and the two are slid back and forth on the guiding rod, which improves the stability of the first conductor assembly and the second conductor assembly when the device switches the path at high speed and moves, and avoids the generation of the cantilever phenomenon.

[0044] In one embodiment of the present application, it further includes a power supply module and a control module. The power supply module is electrically connected to the control module and the drive motor, and is used to control the operation of the drive motor.

[0045] In summary, the present application includes at least one of the following beneficial technical effects:

[0046] 1. By integrating the four ports of the switch together and connecting them with coaxial transmission lines, the transmission distance between the interconnected ports can be effectively shortened, the loss is reduced, and at the same time, the device can select a reasonable port orientation for layout according to different working conditions, so that the device can achieve short-distance and low-loss data transmission in different space environments.

[0047] 2. By chamfering or rounding the internal microwave reed switches of the device, the electric field distribution formed by the microwave reed switches is changed, the electric field performance is optimized, and it becomes more uniform and stable.

[0048] 3. By processing the surface of the inner conductor with key grooves, the torsional resistance of the inner conductor is improved, so that when the conductor assembly is in contact with the inner conductor and is electrically connected, the inner conductor will not deflect inside the insulating layer due to frequent high-speed path switching.

[0049] 4. By providing a first cut plane and a second cut plane on the inner conductor and the microwave reed switch that are adapted to the conductor assembly, when the two ends of the conductor assembly are in point contact with the microwave reed switch and the inner conductor respectively, the contact surface is wider and the electrical connection performance is better.

[0057] The following further elaborates on a microwave port 2x2 matrix switch provided by the present application in conjunction with the attached Figures 1-6 drawings.

[0058] Please refer to Figures 1-6 , which is a microwave port 2x2 matrix switch provided in the first embodiment of the present application, including: a main body housing with a hollow interior, a first conductor component and a second conductor component, a coaxial transmission component, and a driving member 4

[0059] The first microwave port 11 and the second microwave port 12 are respectively arranged on the left and right sides of the upper end of the main body housing 1, and the third microwave port 13 and the fourth microwave port 14 are respectively arranged on the left and right sides of the lower end of the switch main body. Among them, the first microwave port 11, the second microwave port 12, the third microwave port 13, and the fourth microwave port 14 can be installed on the main body housing 1;

[0060] Two groups of first conductor components 31 and second conductor components 32 are respectively arranged inside the upper and lower ends of the main body housing 1;

[0061] The coaxial transmission component 2 is disposed inside the main body housing 1 and is located between the first conductor component 31 and the second conductor component 32. The upper end of the coaxial transmission component 2 is selectively connected to the first microwave port 11 or the second microwave port 12 through the first conductor component 31, and the lower end of the coaxial transmission component 2 is selectively connected to the third microwave port 13 or the fourth microwave port 14 through the second conductor component 32;

[0062] The driving member 44 is disposed on the front side or the rear side of the main body housing 1 and is used to drive the first conductor component 31 and the second conductor component 32 to move in the front-rear direction, so that the first conductor component 31 is selectively connected to the first microwave port 11 or the second microwave port 12;

[0063] and the second conductor component 32 is selectively connected to the third microwave port 13 or the fourth microwave port 14; when the upper end of the coaxial transmission component 2 is connected to the first microwave port 11 through the first conductor component 31, by controlling the movement of the second conductor component 32, the lower end of the coaxial transmission component 2 is selected to be connected to the third microwave port 13 or the fourth microwave port 14, so that the signal can be input from the first microwave port 11 and output in the reverse direction from the third microwave port 13, or the signal can be input from the first microwave port 11 and output in the same direction from the fourth microwave port 14;

[0064] Similarly, when the upper end of the coaxial transmission component 2 is connected to the second microwave port 12 through the first conductor component 31, the signal can also be input from the second microwave port 12 and output in the same direction from the third microwave port 13, or the signal can be input from the first microwave port 11 and output in the reverse direction from the fourth microwave port 14, so that the entire device can select a port to switch the path according to the actual working conditions. Since the first microwave port 11, the second microwave port 12, the third microwave port 13 and the fourth microwave port 14 are integrated together and arranged vertically, and the coaxial transmission component 2 is used for data transmission, the data transmission path is shortened.

[0065] In this embodiment, both the first conductor component 31 and the second conductor component 32 are metal conductors.

[0066] The first microwave port 11, the second microwave port 12, the third microwave port 13 and the fourth microwave port 14 are horizontally disposed on the housing of the main body housing 1. When the microwave ports of the device are horizontally disposed, the device can achieve horizontal input and output in the same direction or horizontal reverse according to the actual working condition requirements;

[0067] The first microwave port 11, the second microwave port 12, the third microwave port 13, and the fourth microwave port 14 are vertically arranged on the housing 1 of the main body. When the microwave ports of the device are vertically arranged, the device can achieve reverse output at different positions in the vertical direction, so that the device can select and customize the switching device with different port orientations according to the spatial layout of different usage environments.

[0068] One end of the first microwave port 11, the second microwave port 12, the third microwave port 13, and the fourth microwave port 14 are respectively provided with corresponding first microwave reeds 110, second microwave reeds 120, third microwave reeds 130, and fourth microwave reeds 140. One end of the first microwave reed 110, the second microwave reed 120, the third microwave reed 130, and the fourth microwave reed 140 close to the coaxial transmission component 2 are all provided with a first cut plane. Among them, the number of the first cut planes is four, namely the first reed cut plane 111, the second reed cut plane 121, the third reed cut plane 131, and the fourth reed cut plane 141. The first reed cut plane 111 is arranged on the first microwave reed 110, the second reed cut plane 121 is arranged on the second microwave reed 120, the third reed cut plane 131 is arranged on the third microwave reed 130, and the fourth reed cut plane 141 is arranged on the fourth microwave reed 140. By setting the first cut plane, when the first microwave reed 110 and the second microwave reed 120, the third microwave reed 130 and the fourth microwave reed 140 are respectively in contact with the first conductor assembly 31 and the second conductor assembly 32, the connection stability is improved.

[0069] In this embodiment, the cut shapes of the first reed cut plane 111, the second reed cut plane 121, the third reed cut plane 131, and the fourth reed cut plane 141 are adapted to the first conductor assembly 31 and the second conductor assembly 32, so that all four can be in stable and good contact with the first conductor assembly 31 and the second conductor assembly 32.

[0070] The first microwave reed 110, the second microwave reed 120, the third microwave reed 130, and the fourth microwave reed 140 are all chamfered or rounded. By chamfering or rounding the respective corners of the first microwave reed 110, the second microwave reed 120, the third microwave reed 130, and the fourth microwave reed 140, the rectangular electric field formed by the four has a more uniform distribution of electric field strength, thereby optimizing the electromagnetic field performance of the entire switch and enabling the device to work more stably.

[0071] In this embodiment, the chamfers or fillets of the first microwave reed 110, the second microwave reed 120, the third microwave reed 130, and the fourth microwave reed 140 can be processed by stamping or grinding.

[0072] The first conductor assembly 31 includes: a first connection conductor 310 and a second connection conductor 311;

[0073] The first connection conductor 310 moves in the front-back direction, so that one end thereof is connected to or disconnected from the first microwave reed 110, and the other end is connected to or disconnected from the upper end of the coaxial transmission assembly 2;

[0074] The second connection conductor 311 moves in the front-back direction, so that one end thereof is connected to or disconnected from the second microwave reed 120, and the other end is connected to or disconnected from the upper end of the coaxial transmission assembly 2;

[0075] The second conductor assembly 32 includes: a third connection conductor 320 and a fourth connection conductor 321;

[0076] The first connection conductor 310 moves in the front-back direction, so that one end thereof is connected to or disconnected from the third microwave reed 130, and the other end is connected to or disconnected from the lower end of the coaxial transmission assembly 2;

[0077] The fourth connection conductor 321 moves in the front-back direction, so that one end thereof is connected to or disconnected from the fourth microwave reed 140, and the other end is connected to or disconnected from the lower end of the coaxial transmission assembly 2.

[0078] When it is necessary to connect the first microwave port 11 and the third microwave port 13, control the first connection conductor 310 to move so that its two ends are respectively connected to the first microwave reed 110 and the upper end of the coaxial transmission assembly 2. At the same time, control the third connection conductor 320 to move so that its two ends are respectively connected to the third microwave reed 130 and the lower end of the coaxial transmission assembly 2, thereby completing the reverse connection between the first microwave port 11 and the third microwave port 13;

[0079] Similarly, when it is necessary to connect the first microwave port 11 and the fourth microwave port 14, control the fourth connection conductor 321 to move so that its two ends are respectively connected to the fourth microwave reed 140 and the lower end of the coaxial transmission assembly 2;

[0080] When it is necessary to connect the second microwave port 12 and the third microwave port 13, control the second connection conductor 311 to move so that its two ends are respectively connected to the second microwave reed 120 and the upper end of the coaxial transmission assembly 2;

[0081] When it is necessary to connect the second microwave port 12 and the fourth microwave port 14, control the fourth connection conductor 321 to move so that its two ends are respectively connected to the fourth microwave reed 140 and the lower end of the coaxial transmission assembly 2.

[0082] In other embodiments, when the first microwave port 11, the second microwave port 12, the third microwave port 13, and the fourth microwave port 14 are vertically disposed on the housing 1 of the main body, the connection positional relationship between the first conductor assembly 31 and the second conductor assembly 32 and the four microwave ports is as shown in the attached drawings of the specification Figure 6 As shown, when each port is interconnected, the motion state of each connecting conductor is the same as that when the ports are horizontally disposed, so it will not be elaborated here.

[0083] It further includes a driving housing disposed on the front side or the rear side of the main body housing 1. The number of the driving members 4 is four groups, and all of them are disposed on the driving housing;

[0084] Each group of the driving members 4 includes: a driving motor, a pushing member, and a connecting rod 44;

[0085] The driving motor is disposed in the front-rear direction and is assembled on the driving housing. Among them, the driving motor can be a stepping motor;

[0086] The pushing member is disposed in the front-rear direction. One end of the pushing member is connected to the driving shaft of the driving motor 41. Among them, the pushing member can include a lead screw 42 and a hollow tube 43;

[0087] One end of the hollow tube 43 is coaxially sleeved outside the lead screw 42, and a thread groove that is in threaded cooperation with the lead screw 42 is provided inside. The hollow tube 43 is slidably assembled on the main body housing 1 in the front-rear direction;

[0088] One end of the connecting rod 44 is fixedly connected to the other end of the pushing member;

[0089] The four groups of the driving members 4 are respectively connected to the first connecting conductor 310, the second connecting conductor 311, the third connecting conductor 320, and the fourth connecting conductor 321 through the connecting rod 44. When it is necessary to drive the first connecting conductor 310, the second connecting conductor 311, and the third connecting conductor 320 to move in the front-rear direction, the driving motor operates. The driving motor drives the lead screw 42 to rotate. When the lead screw 42 rotates, it cooperates with the thread groove inside the hollow tube 43, so that the hollow tube 43 moves in the front-rear direction inside the main body housing 1, and further drives the connected connecting conductor to move back and forth. By controlling the rotation direction and rotation speed of the stepping motor, and limiting the length of the hollow tube 43, the stroke of the movement of the first connecting conductor 310, the second connecting conductor 311, the third connecting conductor 320, and the fourth connecting conductor 321 is realized, so that when it contacts the corresponding microwave reed, the impact generated during contact can be reduced, and the loss inside the device is avoided.

[0090] The coaxial transmission assembly 2 includes;

[0091] An outer conductor 21, the outer conductor 21 is arranged in the main body housing 1 in the up and down direction;

[0092] An insulating layer 22, the insulating layer 22 is coaxially arranged inside the outer conductor 21;

[0093] An inner conductor 23, the inner conductor 23 is coaxially arranged inside the insulating layer 22, the upper and lower ends of the inner conductor 23 respectively extend to the front side or the rear side of the first conductor assembly 31 and the second conductor assembly 32, and second cut planes 230 are respectively arranged on the front side or the rear side of the upper and lower ends of the inner conductor 23. Among them, the second cut plane 230 is a rectangular surface with a width equal to the diameter of the inner conductor 23. At the same time, when it is connected and in contact with the corresponding first conductor assembly 31 and second conductor assembly 32, the contact area is wider and the point connection is more stable.

[0094] Axially extending key grooves are annularly distributed outside the inner conductor 23. Since when the upper and lower ends of the inner conductor 23 are connected to the first conductor assembly and the second conductor assembly 32, the left side or the right side of the second cut plane 230 at the upper and lower ends of the inner conductor 23 is in contact with the corresponding connecting conductor, during the process of high-speed switching of the path, the force on the inner conductor 23 on the second cut plane 230 is uneven and it is easy to rotate. By arranging the key grooves, the torsional resistance of the inner conductor 23 can be effectively improved, thus avoiding the occurrence of the above situation.

[0095] It further includes a guide rod 5 arranged in the front and rear direction. The guide rod 5 is assembled below the first conductor assembly 31 and the second conductor assembly 32, and is used to support the first conductor assembly 31 and the second conductor assembly 32, and enable the first conductor assembly and the second conductor assembly 32 to slide on the guide rod 5. When the first conductor assembly 31 and the second conductor assembly 32 move, the guide rod 5 can support the first conductor assembly 31 and the second conductor assembly 32, reducing the loss brought to the driving shaft of the driving motor during long-term high-speed movement.

[0096] In this embodiment, the guide rod 5 can also be replaced with a rectangular plate extending in the front and rear direction, which can also play a supporting effect on the first conductor assembly 31 and the second conductor assembly 32.

[0097] It further includes a power supply module and a control module. The power supply module is electrically connected to the control module and the driving motor, and is used to control the operation of the driving motor.

[0098] In this embodiment, the electrical connection manner of the power supply module and the control module to the driving motor 41 is an existing conventional technical means, so it will not be elaborated here.

[0099] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
