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 distributed in the upper and lower directions, and the coaxial transmission component 2 is used to transmit data, the data transmission path is shortened.

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 in contact with the first conductor component 31 and the second conductor component 32 respectively, the connection stability is improved.

[0037] 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 component 31 and the second conductor component 32, so that all four can have stable and good contact with the first conductor component 31 and the second conductor component 32.

[0038] 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 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, so that the device can work more stably.

[0040] The first conductor assembly 31 includes: a first connecting conductor 310 and a second connecting conductor 311; The first connecting conductor 310 moves in the front-to-back direction, so that one end thereof is connected to or disconnected from the first microwave reed 110, and the other end thereof is connected to or disconnected from the upper end of the coaxial transmission component 2; The second connecting conductor 311 moves in the front-to-back direction, so that one end thereof is connected to or disconnected from the second microwave reed 120, and the other end thereof is connected to or disconnected from the upper end of the coaxial transmission component 2; The second conductor assembly 32 includes: a third connecting conductor 320 and a fourth connecting conductor 321; The first connecting conductor 310 moves in the front-to-back direction, so that one end thereof is connected to or disconnected from the third microwave reed 130, and the other end thereof is connected to or disconnected from the lower end of the coaxial transmission component 2; The fourth connecting conductor 321 moves in the front-to-back direction, so that one end of it 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 component 2. When the first microwave port 11 needs to be connected to the third microwave port 13, the first connecting conductor 310 is controlled to move so that its two ends are respectively connected to the first microwave reed 110 and the upper end of the coaxial transmission component 2, and the third connecting conductor 320 is controlled to move so that its two ends are respectively connected to the third microwave reed 130 and the lower end of the coaxial transmission component 2, thereby completing the reverse connection between the first microwave port 11 and the third microwave port 13; Similarly, when the first microwave port 11 needs to be connected to the fourth microwave port 14, the fourth connecting conductor 321 is controlled to move so that its two ends are connected to the fourth microwave reed 140 and the lower end of the coaxial transmission component 2 respectively; When the second microwave port 12 needs to be connected to the third microwave port 13, the second connecting conductor 311 is controlled to move so that its two ends are connected to the second microwave spring 120 and the upper end of the coaxial transmission component 2 respectively; When the second microwave port 12 needs to be connected to the fourth microwave port 14 , the fourth connecting conductor 321 is controlled to move so that its two ends are connected to the fourth microwave reed 140 and the lower end of the coaxial transmission component 2 respectively.

[0041] 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 arranged on the shell of the main shell 1, the connection position relationship between the first conductor component 31 and the second conductor component 32 and the four microwave ports is as shown in the appendix of the specification. Figure 6 As shown, when the ports are interconnected, the movement state of each connecting conductor is consistent with the movement state when the ports are horizontally arranged, so it will not be described here.

[0042] It also includes a driving housing disposed on the front side or the rear side of the main housing 1, and the number of the driving members 4 is four groups, and all are disposed on the driving housing; Each set of the driving members 4 includes: a driving motor, a pushing member and a connecting rod 44; The driving motor is arranged along the front-to-back direction and assembled on the driving housing, wherein the driving motor may be a stepping motor; A push member, the push member is arranged along the front-rear direction, one end of the push member is connected to the driving shaft of the driving motor 41, wherein the push member may include a screw rod 42 and a hollow tube 43; One end of the hollow tube 43 is coaxially sleeved on the outside of the screw rod 42, and a thread groove is provided inside to match the thread of the screw rod 42. The hollow tube 43 is slidably assembled on the main housing 1 along the front-back direction; One end of the connecting rod 44 is connected and fixed to the other end of the pushing member; The four groups of 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-to-back direction, the driving motor is activated, and the driving motor drives the screw rod 42 to rotate. When the screw rod 42 rotates, it cooperates with the thread groove inside the hollow tube 43, so that the hollow tube 43 moves in the front-to-back direction inside the main shell 1, and then drives the connecting conductor connected thereto to move back and forth. By controlling the rotation direction and rotation speed of the stepping unit and limiting the length of the hollow tube 43, the movement stroke 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 they contact with the corresponding microwave reed, the impact generated during contact can be reduced, thereby avoiding losses inside the device.

[0043] The coaxial transmission component 2 includes: An outer conductor 21, the outer conductor 21 is arranged in the main housing 1 along the up-down direction; An insulating layer 22, wherein the insulating layer 22 is coaxially disposed inside the outer conductor 21; The inner conductor 23 is coaxially arranged inside the insulating layer 22, and the upper and lower ends of the inner conductor 23 extend to the front or rear side of the first conductor component 31 and the second conductor component 32 respectively. The front or rear side of the upper and lower ends of the inner conductor 23 are both provided with a second incision plane 230, wherein the second incision plane 230 is a rectangular surface with a width equal to the diameter of the inner conductor 23, and at the same time, when connected and contacted with the corresponding first conductor component 31 and the second conductor component 32, the contact area is wider and the point connection is more stable.

[0044] The inner conductor 23 is provided with a keyway extending in an axial direction in an annular shape on the outside. 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 or right side of the second cut plane 230 located at the upper and lower ends of the inner conductor 23 contacts the corresponding connecting conductor. During the high-speed switching of the path, the inner conductor 23 is subjected to uneven force on the second cut plane 230 and is prone to rotation. By providing the keyway, the torsional resistance of the inner conductor 23 can be effectively improved, thereby avoiding the above situation.

[0045] It also includes a guide rod 5 arranged along the front-to-back direction, and the guide rod 5 is assembled below the first conductor component 31 and the second conductor component 32, and is used to support the first conductor component 31 and the second conductor component 32, and enable a conductor component and a second conductor component 32 to slide on the guide rod 5. When the first conductor component 31 and the second conductor component 32 move, the guide rod 5 can support the first conductor component 31 and the second conductor component 32, thereby reducing the loss caused to the drive shaft of the drive motor due to long-term high-speed movement.

[0046] In this embodiment, the guide rod 5 may also be replaced by a rectangular plate extending in the front-to-back direction, which can also play a supporting role for the first conductor assembly 31 and the second conductor assembly 32 .

[0047] It also includes a power supply module and a control module. The power supply module is electrically connected to the control module and the drive motor to control the operation of the drive motor.
