Wherein, the cylindrical metal pipe includes the metal lateral wall and by the hollow inner chamber of metal lateral wall formation. To achieve support for the second inner conductor 121 and the second outer conductor 122, the second insulating layer 123 is filled with PE material. Alternatively, the second insulating layer 123 may be filled with insulating materials of other materials, such as PVC, XLPE, and the like.

The rotation member 13 includes a third inner conductor 134, a third outer conductor 135, and a third insulating layer 136 formed between the third inner conductor 134 and the third outer conductor 135.

Alternatively, the third insulating layer 136 may be filled with insulating materials of other materials, such as PVC, XLPE, etc.

In order to achieve the nesting of the rotating member 13 with the first fixing member 11 and the second fixing member 12, the rotating member 13 is further provided with a first nesting portion 131, a second nesting portion 132 and a connecting portion 133, and the connecting portion 133 is used for connecting the first nesting portion 131 and the second nesting portion 132.

The diameter of the first nesting part 131 is smaller than that of the first fixing part 11, that is, the diameter of the third outer conductor 135 at the first nesting part 131 is smaller than that of the first outer conductor 112 of the first fixing part 11; the diameter of the third inner conductor 134 at the first nest 131 is smaller than the diameter of the first inner conductor 111 of the first fixing 11 so that the third inner conductor 134 can be embedded in the first inner conductor 111. Meanwhile, the first fixing member 11 and the first nesting portion 131 are not filled with insulating materials at the same length. The embodiment is arranged in such a way that the first nesting part 131 can be nested in the first fixing piece 11.

The diameter of the second nesting part 132 is smaller than that of the first fixing part 11, that is, the diameter of the third outer conductor 135 at the second nesting part 132 is smaller than that of the second outer conductor 122 of the second fixing part 12; the diameter of the third inner conductor 134 at the second nest 132 is smaller than the diameter of the second inner conductor 121 of the second fixing piece 12 so that the third inner conductor 134 can be embedded in the second inner conductor 121.

The diameter of the connecting portion 133 is the same as the diameter of the first fixing member 11 and the diameter of the second fixing member 12. When the first and second nesting portions 131 and 132 are completely nested in the first and second fixed members 11 and 12, respectively, the third outer conductor 135 of the rotating member 13 is in contact with the first outer conductor 112 of the first fixed member 11 and the second outer conductor 122 of the second fixed member 12, so that signal overflow can be effectively prevented.

Alternatively, the present application may also change the diameters of the first inner conductor 111, the second inner conductor 121, and the third inner conductor 134, and thus the nesting manner of the rotating element 13 with the first fixed element 11 and the second fixed element 12, respectively. Referring further to fig. 4, fig. 4 is a schematic structural diagram of a second embodiment of the coaxial tunable phase shifter of the present application.

As shown in fig. 4, the third inner conductors 134 located in the first nest 131, the second nest 132, and the connection portion 133 have the same diameter. The diameter of the first inner conductor 111 in the region where the first nest 131 is fitted is smaller than the diameter of the third inner conductor 134 in the first nest 131, that is, the first anchor 11 is fitted into the first nest 131 in such a manner that the first inner conductor 111 is fitted into the third inner conductor 134. The diameter of the second inner conductor 121 in the region where the second nesting part 132 is nested is smaller than the diameter of the third inner conductor 134 in the second nesting part 132, that is, the second fixing member 12 is nested in the second nesting part 132 in such a way that the second inner conductor 121 is embedded in the third inner conductor 134. Alternatively, the coaxial tunable phase shifter 10 of the present application can combine the first embodiment and the second embodiment to realize the nesting of the second fixing member 12 and the second nesting portion 132. For example, the diameter of the third inner conductor 134 at the first nest 131 is smaller than the diameter of the first inner conductor 111 of the first fixing member 11, while the diameter of the second inner conductor 121 at the region where the second nest 132 is nested is smaller than the diameter of the third inner conductor 134 at the second nest 132; or the diameter of the first inner conductor 111 at the nesting area with the first nesting part 131 is smaller than that of the third inner conductor 134 at the first nesting part 131, and the diameter of the third inner conductor 134 at the second nesting part 132 is smaller than that of the second inner conductor 121 of the second fixing part 12. The coaxial tunable phase shifter 10 of the present application employs multiple nesting ways to improve the diversity and possibility of nesting.

Referring to fig. 2 in conjunction with fig. 1, fig. 2 is a schematic diagram of the coaxial tuneable phase shifter of fig. 1 in a first position.

As shown in fig. 2, the third inner conductor 134 at the first nesting portion 131 is just embedded in the first inner conductor 111 of the first fixing member 11, the third inner conductor 134 at the second nesting portion 132 is just embedded in the second inner conductor 121 of the second fixing member 12, and the signal is transmitted through the first inner conductor 111, the second inner conductor 121, and the third inner conductor 134 in sequence. At this time, the electrical length L of the coaxial tunable phase shifter 10₁Is the maximum value equal to the sum of the length of the first inner conductor 111 of the first fixed member 11, the length of the second inner conductor 121 of the second fixed member 12, and the length of the third inner conductor 134 of the rotating member 13.

Referring to fig. 3 in conjunction with fig. 1-2, fig. 3 is a view of the coaxial tunable phase shifter of fig. 1A schematic view of the structure at the second position. When the coaxial tunable phase shifter 10 is located at the second position, the first nesting portion 131 of the rotating member 13 is completely nested with the first fixed member 11, and the second nesting portion 132 of the rotating member 13 is completely nested with the second fixed member 12. At this time, the electrical length L of the coaxial tunable phase shifter 10₂Is a minimum value equal to the sum of the length of the first inner conductor 111 of the first fixed member 11, the length of the second inner conductor 121 of the second fixed member 12, and the length of the third inner conductor 134 of the rotating member 13 at the connecting portion 133.

Referring to fig. 2-3, the electrical length L of the coaxial tunable phase shifter 10 in the second position is shown₂Is less than the electrical length L of the coaxial tunable phase shifter 10 in the first position₁And the phase change of the coaxial tunable phase shifter 10 is affected by the electrical length, so the phases of the coaxial tunable phase shifter 10 at the two positions are different. The phase of the coaxial adjustable phase shifter 10 is adjusted.

In this embodiment, the phase of the coaxial phase shifter 10 can be adjusted by rotating the rotating member 13, which is simple to operate, and meanwhile, the structure of the coaxial phase shifter 10 is simple, which can reduce the production cost.

Alternatively, the coaxial tunable phase shifter 10 may be located at other positions to vary the electrical length of the coaxial tunable phase shifter 10 to enable adjustment of the phase of the coaxial tunable phase shifter 10. Optionally, the electrical length of the coaxial tunable phase shifter 10 is greater than or equal to L₂Is less than or equal to L₁。

Referring further to fig. 5, fig. 5 is a schematic structural diagram of a third embodiment of the coaxial tunable phase shifter of the present application. The coaxial tunable phase shifter 10 further includes a knob 14, and the knob 14 is disposed on the connecting portion 133 of the rotation member 13. In this embodiment, the rotating member 13 can be driven to rotate by the knob 14, and the operation is simple and convenient.

The present application also provides a communication device comprising a coaxial tuneable phase shifter 10 as described above, the coaxial tuneable phase shifter 10 being adapted to adjust the phase of the communication device.
