[0030] Before describing in detail the various embodiments of the present application, the technical concept of the present application is first briefly described: the current base station antennas usually use traditional welding methods to weld the various component units, especially when the number of components is large, there is a great difficulty in assembly, and the degree of integration is also low. To this end, the integrated combining vertical phase shifter provided by the present invention installs each phase-shifting feed network component in a shell, and the phase-shifting feed network components are combined and connected through the feed network combining pins, and a feeder seat is installed on the outside of the shell, so that the radiation unit is plugged into the feeder seat and passes through the shell to connect with the feeding contact of the phase-shifting feed network component, wherein the phase-shifting feed network component integrates unrestricted functions such as phase shifter, combiner, filter, power divider, etc., and there is no need to weld between the radiation unit and the phase-shifting feed network component, which improves the degree of integration and reduces the welding process, which is conducive to more convenient assembly of devices. The specific principle of the integrated combining vertical phase shifter of the present application is described below in combination with more embodiments.

[0031] Embodiment 1

A plurality of feed network combining pins 20 are respectively connected to the combining parts relative to each group of phase-shifting feed network components 10. The feeder socket 40 is installed on the outer wall of the housing 30 for connecting the radiation unit. A through hole 31 is provided on the outer wall of the housing 30. The cable of the radiation unit passes through the through hole 31 to be connected with the feeding contact of the phase-shifting feed network component. That is, the plurality of groups of phase-shifting feed network components 10 are distributed at intervals in the receiving space and the positions of the combining parts between the groups of phase-shifting feed network components 10 correspond to each other, so that the feed network combining pins 20 can connect the combining parts at relative positions to realize the combining connection between the phase-shifting feed network components 10, thereby improving the degree of integration, reducing the welding process and facilitating the assembly of the device.

[0033] In this embodiment, there may be multiple feeder sockets 40 and multiple feeder network combining pins 20 , and the number is configured according to specific needs.

[0034] For example, see Figure 2 The shape of the shell 30 matches the shape of the phase-shifting feed network component 10. For example, the shell 30 is a long flat shell. In an optional embodiment, a plurality of partitions 32 are provided in the receiving space of the shell 30 to form a plurality of independent chambers 33. Each group of phase-shifting feed network components 10 is installed in each chamber 33. The partitions 32 and the shell 30 are provided with corresponding latch avoidance holes 34. The latch avoidance holes 34 are located at the installation position of the feed network combining pin 20. That is, the latch avoidance holes 34 can reserve operating space for the feed network combining pin 20. Figure 2 In this embodiment, two groups of phase-shifting feed network components 10 are specifically used as examples for explanation. For this purpose, the receiving space in the housing 30 can be divided into two independent chambers 33 stacked up and down by one or more partitions 32. At the same time, corresponding plug avoidance holes 34 are provided on the partitions 32 and the housing 30 at the installation positions corresponding to the feed network combining plugs 20, so that the feed network combining plugs 20 can extend from the plug avoidance holes 34 on the outer wall of the housing 30 into the chamber 33 and connect with the combining part of the phase-shifting feed network component 10. Of course, in other examples, the distribution between the multiple chambers 33 can be either stacked up and down or arranged left and right.

[0035] Furthermore, the inner wall of the shell 30 of this embodiment is provided with a guide rail 35, and the phase-shifting feed network assembly 10 is provided with a guide groove 12 adapted to the guide rail 35, and the guide groove 12 is slidably connected to the guide rail 35, that is, through the sliding connection between the guide groove 12 and the guide rail 35, the phase-shifting feed network assembly 10 can be slidably embedded in the corresponding chamber 33.

[0036] A welding section 36 is also provided on the outer wall of the housing 30 , and the feeder seat 40 is welded at the welding section 36 ; illustratively, the feeder seat 40 may be welded to the welding section 36 by using a laser welding process.

[0037] For example, see Figure 3 Each group of phase-shifting feed network components 10 includes a phase-shifting feed network 13 and a phase-shifting medium 14. The combining portion on the phase-shifting feed network 13 is provided with a feed network welding hole, and the feed network combining plug 20 is used to be plugged into the feed network welding hole to feed and connect each group of phase-shifting feed network components; in this embodiment, the feed network combining plug 20 extends from the plug avoidance hole 34 on the shell 30 into the chamber 33 and is plugged into the feed network welding hole of the upper phase-shifting feed network component 10, and further passes through the feed network welding hole of the upper phase-shifting feed network component 10, and then passes through the plug avoidance hole 34 on the partition 32, and then is plugged into the feed network welding hole of the lower phase-shifting feed network component 10; thereby, the upper and lower phase-shifting feed network components 10 are combined and connected through the feed network combining plug 20.

[0038] Furthermore, the phase-shifting media 14 of the present embodiment are arranged in pairs on two opposite sides of the phase-shifting feed network 13, and the phase-shifting media 14 can be movably arranged relative to the phase-shifting feed network 13 to adjust the phase of the antenna output signal; specifically, a plurality of phase-shifting media 14 arranged at intervals are arranged on two opposite sides of the phase-shifting feed network 13, and the phase of the antenna output signal can be adjusted by movable adjustment of the phase-shifting media 14 relative to the phase-shifting feed network 13.

[0039] For example, see Figure 1 and Figure 4 This embodiment also includes an end wire retaining buckle 50, which can detachably cover the opening of the receiving space to limit the displacement of the phase-shifting feeding network component 10; specifically, the opening of the receiving space is arranged on the end surface of the shell 30, and the end wire retaining buckle 50 is used to detachably cover the end surface of the shell 30, and at the same time limit the phase-shifting feeding network component 10 in the receiving space. Exemplarily, the end wire retainer 50 is a cover-like structure, and its shape matches the cross-sectional shape of the shell 30; wherein, the end wire retainer 50 includes a limiting end face 51, a limiting column 52, and a wire retainer claw 53, and the limiting end face 51 abuts against the end faces of the shell 30 and the phase-shifting feed network component 10, and the limiting end face 51 can prevent it from falling off the shell 30; and an avoidance hole 54 is opened on the limiting end face 51, and the phase-shifting feed network component 10 partially passes through the avoidance hole 54 to extend out of the shell 30, wherein the part of the phase-shifting feed network component 10 extending out of the shell 30 can be used to be fixed with other phase-shifting feed network components; the limiting column 52 is inserted into the end wire retainer positioning hole 38 on the outer wall of the shell 30 so that the end wire retainer 50 is limited and fixed to the shell 30; the wire retainer claw 53 is used to clamp the coaxial cable.

[0040] Furthermore, it also includes a plurality of middle wire retaining buckles 60, which are installed on one side of the feeder seat 40 on the outer wall of the housing 30 and are also used to clamp the coaxial cable. Specifically, a middle wire retaining buckle 60 can be installed on one side of each feeder seat 40, and the coaxial cable is clamped by the wire buckle claws provided on the middle wire retaining buckle 60.

[0041] The integrated combined vertical phase shifter of this embodiment improves the degree of integration and reduces the welding process, which is conducive to more convenient assembly of the device.

[0044] Furthermore, the green antenna further comprises a phase shifter vertical support member 300, which is assembled with the integrated vertical phase shifter 100 and detachably mounted on the substrate 200, so as to fix the integrated vertical phase shifter 100 on the substrate 200.

Specifically, the outer wall of the shell 30 of the integrated vertical phase shifter 100 is provided with a fixing buckle slot 37, and the phase shifter vertical support member 300 is clamped on the fixing buckle slot 37; the phase shifter vertical support member 300 is designed as a clamping structure, thereby the phase shifter vertical support member 300 is clamped on the fixing buckle slot 37 for limited fixing, and then installed on the substrate 200 through the supporting positioning column 301 at the bottom of the phase shifter vertical support member 300, so as to realize the stable connection between the phase shifter vertical support member 300 and the shell 30. Among them, the number of the phase shifter vertical support member 300 and the fixing buckle slot 37 can be multiple.

[0045] Furthermore, the green antenna also includes a transmission connection member 400, and the part of each integrated vertical phase shifter phase shifter feed network assembly 10 extending out of the housing 30 is provided with a transmission member installation groove 15, and the transmission connection member 400 is connected to the transmission member installation groove 15. For example, Figure 7As shown, the upper and lower ends of the transmission connector 400 are respectively provided with a rotating shaft 401, and the rotating shaft 401 is inserted into the transmission component installation groove 15 to achieve relative fixation of each phase-shifting feed network assembly 10. Exemplarily, a stop step 402 is also provided on the rotating shaft 401, and the stop step 402 can prevent the rotating shaft 401 from falling off from the phase-shifting feed network assembly 10 to ensure stable connection. Among them, the transmission component installation groove 15 is located in the phase-shifting medium 14, so that the synchronous phase shifting function can be achieved through the connection of the transmission connector 400.

[0046] The following describes the assembly process of the green antenna of the second embodiment:

[0047] 1. First, slide each group of phase-shifting feed network components 10 into each chamber 33, and insert the feed network combining pin 20 into the pin avoidance hole 34, so that each phase-shifting feed network component 10 is combined and connected;

[0048] 2. Then, the end wire buckles 50 are sleeved on both ends of the housing 30 to achieve the limit fixation of the phase-shifting feeding network assembly 10. At the same time, the middle wire buckle 60 is sleeved on one side of each group of feeder seats 40 in the housing 30. Then, the radiation unit connecting cable is plugged into the feeder seat 40. The cable of the radiation unit passes through the through hole 31 and is connected to the feeding contact 11 of the phase-shifting feeding network assembly 10.

[0049] 3. Then, each integrated vertical phase shifter 100 is installed side by side on the substrate 200 through the phase shifter vertical support 300, and the transmission connecting member 400 is connected to the transmission member installation groove 15 of two adjacent phase shifting feed network components 10.
