Problems solved by technology

[0003] In order to save the space of the phase shifter, an arc-shaped phase shifter has appeared on the market, including a circuit board and a slide that rotates on the circuit board. In order to enable the slide to rotate along the circuit board, an arc Shaped phase shifters need to drill holes on the circuit board, and then install the rotating shaft and the sliding piece at the punching place to connect, and when in use, a large number of heat, which affects the life of the phase shifter

Embodiment 1

[0025] Example 1, such as Figure 1 to Figure 3 As shown, the rotating structure of a phase shifter described in this embodiment includes a support plate 1, a first fixed cover 2 disposed on the support plate 1, a first circuit board 3 disposed on the support plate 1, and a sliding The first slide 4 provided on the first circuit board 3; the first circuit board 3 is provided with a first transmission line 31; the first slide 4 is provided with a second transmission line 41 matched with the first transmission line 31 ;

[0026] The first sliding piece 4 is provided with a rotating block 42 ; the rotating block 42 is extended with a rotating shaft 43 ;

[0027] Specifically, the rotation structure of the phase shifter described in this embodiment, by setting the first fixed cover 2 on the support plate 1, and rotating the rotating shaft 43 of the rotating block 42 on the first fixed cover 2, thereby realizing the first The sliding plate 4 has the function of sliding on the fir...

Embodiment 2

[0040] Example 2, such as Figure 4 As shown, the difference from Embodiment 1 is that in the rotating structure of a phase shifter described in this embodiment, the first fixed cover 2 is provided with a second placement groove 72 for placing the rotating block 42; The second placement groove 72 is provided with a through hole for the rotating shaft 43 to pass through; the bottom of the second placement groove 72 is pressed against the top of the rotating block 42 .

[0041] Specifically, through the above arrangement, the first sliding piece 4 can be closely attached to the first circuit board 3 , so that the second transmission line 41 is closely attached to the first transmission line 31 , preventing the first sliding piece 4 from shaking up and down.

Abstract

The invention relates to the technical field of phase shifters, in particular to a rotating structure of a phase shifter, the rotating structure comprises a support plate, a first fixed cover arrangedon the support plate, a first circuit board arranged on the support plate and a first sliding sheet arranged on the first circuit board in a sliding manner, a first transmission line is arranged on the first circuit board; the first sliding sheet is provided with a second transmission line matched with the first transmission line; the first sliding sheet is provided with a rotating block; a rotating shaft extends from the rotating block; and the rotating shaft is rotationally arranged in the first fixed cover. According to the rotating structure, the first fixed cover is arranged on the supporting plate, and the rotating shaft of the rotating block rotates on the first fixed cover, so that the function that the first sliding sheet slides on the first circuit board is achieved, punching does not need to be conducted on the first circuit board, the rotating shaft does not need to be arranged at the punching position, and therefore heating of the phase shifter is reduced; and the servicelife of the phase shifter is prolonged.

Description

technical field [0001] The invention relates to the technical field of phase shifters, in particular to a rotating structure of a phase shifter. Background technique [0002] In the coverage of mobile communication network, the electric adjustable base station antenna is one of the key equipments of the coverage network, and the phase shifter is the core component of the electric adjustable base station antenna. The performance of the phase shifter directly determines the performance of the electric adjustable base station antenna. , which in turn affects the quality of network coverage, so the importance of phase shifters in the field of mobile base station antennas is self-evident. [0003] In order to save the space of the phase shifter, an arc-shaped phase shifter has appeared on the market, including a circuit board and a slide that rotates on the circuit board. In order to enable the slide to rotate along the circuit board, an arc Shaped phase shifters need to drill h...
