Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to a phase shifter mounting assembly and antenna. Background Technology

[0002] For cable-limited base station antenna solutions, the length of the phase shifter is typically equal to the length of the dipole array. Using vertically aligned phase shifters effectively shortens the distance between the phase shifter feed port and the dipole feed plate. Furthermore, a pair of vertically aligned phase shifters can be symmetrically distributed on both sides of the dipole array, thereby shortening the length of the feed lines and reducing transmission losses. However, this vertically aligned configuration results in a higher center of gravity for the phase shifters, and due to space constraints, they are mostly fixed to the reflector at the bottom. During antenna operation, the phase shifters are prone to swaying or shifting, leading to poor stability. Utility Model Content

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In related technologies, for cable-limited base station antenna solutions, the length of the phase shifter is usually equal to the length of the dipole array. Using vertically aligned phase shifters can effectively shorten the distance between the phase shifter feed port and the dipole feed plate. Furthermore, a pair of vertically aligned phase shifters can be symmetrically distributed on both sides of the dipole array, thereby shortening the length of the feed lines and reducing transmission losses. However, with vertically aligned phase shifters, the center of gravity is relatively high, and due to installation space limitations, the phase shifters are mostly fixed to the reflector at the bottom. During antenna operation, the phase shifters are prone to swaying or shifting, resulting in poor stability.

[0034] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides a mounting assembly for a phase shifter 100. The mounting assembly includes a pair of fixing brackets 200 and a first connector 400. The bottoms of the pair of fixing brackets 200 are respectively connected to a reflector, and the fixing brackets 200 are used to mount the phase shifter 100. The first connector 400 is detachably connected to the top of the pair of fixing brackets 200.

[0035] These embodiments aim to address the stability issues encountered by the phase shifter 100 in low-cable base station antenna setups. Specifically, to improve the stability of the phase shifter 100 and precisely control the distance between a pair of phase shifters 100 to reduce phase errors, the specific structural configuration of the mounting assembly is as follows:

[0036] A pair of mounting brackets 200 are connected at their bottoms to a reflector plate for supporting and mounting the phase shifter 100. By directly connecting the mounting brackets 200 to the reflector plate, a robust foundation is provided for the phase shifter 100, contributing to increased stability. Exemplarily, in this embodiment, the mounting brackets 200 and the phase shifter 100 are detachably connected to facilitate subsequent installation of the phase shifter 100 and the feeder line, thus shortening the feeder line length. Of course, in other embodiments, the mounting brackets 200 and the phase shifter 100 may be fixedly connected.

[0037] The first connector 400 is designed for detachable connection to the top of each of the pair of mounting brackets 200. This not only enhances the stability of the overall structure but also facilitates the installation, maintenance, or replacement of the phase shifter 100. Furthermore, by adjusting the first connector 400, the distance between the two phase shifters 100 can be controlled more precisely, thereby effectively reducing phase errors caused by distance variations.

[0038] It should be noted that, based on the connection between the bottom of the fixing frame 200 and the reflector, the tops of the pair of fixing frames 200 are connected by the first connector 400, thus fixing both ends of the pair of fixing frames 200. The pair of fixing frames 200 form a mutual supporting force, constituting a multi-point support system. This obviously improves the stability of the phase shifter 100. Furthermore, since the first connector 400 and the reflector are respectively fixed to both ends of the fixing frame 200, the distance between the fixing frames 200 is fixed, and correspondingly, the distance between the pair of phase shifters 100 is also fixed.

[0039] Therefore, this application solves the problems of high center of gravity and easy shaking of vertically installed phase shifter 100 by optimizing the installation method of phase shifter 100, thereby improving the stability and reliability of antenna system, and also helping to reduce phase error and improve the working efficiency of the entire base station antenna.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the fixing frame 200 has a first plug-in body 212 and a second plug-in body 213, and the first connector 400 has a first plug-in groove 410 and a second plug-in groove 420. The first plug-in body 212 and the second plug-in body 213 are spaced apart, and the first plug-in groove 410 and the second plug-in groove 420 are spaced apart. The first plug-in body 212 passes through the first plug-in groove 410 to form a positioning fit, and the second plug-in body 213 passes through the second plug-in groove 420 to form a positioning fit.

[0041] In these embodiments, to further enhance the stability and accuracy of the phase shifter 100 mounting assembly, the mounting bracket 200 and the first connector 400 employ a plug-in connection. Specifically, each mounting bracket 200 has a first plug-in body 212 and a second plug-in body 213, which are spaced apart, enabling the mounting bracket 200 to not only stably support the phase shifter 100 but also achieve precise positioning with the first connector 400 through the plug-in bodies.

[0042] The first connector 400 has a first insertion slot 410 and a second insertion slot 420. These two insertion slots are also spaced apart. The first connector 400 is mated and connected to corresponding insertion bodies on the mounting bracket 200 via these insertion slots.

[0043] In this structure, the first connector 212 passes through the first connector slot 410 to form a positioning fit, while the second connector 213 passes through the second connector slot 420 to form a positioning fit. This method not only simplifies the installation process and improves assembly efficiency, but also ensures precise positioning between the fixing bracket 200 and the first connector 400, thereby helping to maintain the accurate distance between the pair of phase shifters 100 and reducing phase errors caused by positional deviations.

[0044] In addition, it also increases the stability of the overall structure, because the tight fit between the connector and the slot can effectively prevent the phase shifter 100 from shaking or shifting during operation, which is crucial for improving the reliability and performance of the antenna system.

[0045] For example, the first connector 212 is configured as an upwardly protruding cylinder, and the second connector 213 is configured as a T-shaped protrusion. The first connector 212 is located at one end of a pair of fixing brackets 200 that are close to each other, and the second connector 213 is located at one end of a pair of fixing brackets 200 that are opposite to each other. The T-shaped protrusion has a head and a rod portion, with the rod portion close to the other fixing bracket 200. The first connector groove 410 is configured as a circular hole, and the second connector groove 420 is configured as an open groove at the end of the first connector 400. The circular hole and the cylinder are interference-fitted or clearance-fitted. The sidewall of the open groove abuts against the corresponding sidewall on the rod portion, and the head abuts against the end of the open groove. Of course, in other embodiments, the first connector 212 and the second connector 213 may also be configured as cylinders, ellipsoids, prisms, etc. Similarly, the first connector groove 410 and the second connector groove 420 may also be configured as square holes, ellipsoids, circular holes, etc.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the top of the mounting bracket 200 has a recessed platform 214 on the end face away from the reflector, the plug body is located on the recessed platform 214, and the end face of the first connector 400 near the reflector abuts against the bottom surface of the recessed platform 214.

[0047] In these embodiments, the stability and assembly accuracy of the phase shifter 100 mounting assembly are further improved.

[0048] A recessed platform 214 is provided on the top end face of the mounting bracket 200 opposite to the reflector, and the connector is located within this recessed platform 214. This design helps to ensure a more stable position for the connector and improves the accuracy and stability of the connection between the first connector 400 and the mounting bracket 200 by defining the position of the connector.

[0049] The end face of the first connector 400 near the reflector abuts against the bottom surface of the recessed platform 214. This means that when the first connector 400 is assembled with the mounting bracket 200, it is not only positioned by the cooperation of the plug-in body and the plug-in slot, but its end face also contacts the bottom surface of the recessed platform 214, forming support and limiting. This can enhance the rigidity of the entire structure and reduce the risk of the phase shifter 100 shifting or shaking due to external vibration or other factors.

[0050] Furthermore, it is possible to reduce the height of the entire device in the vertical direction, and at the same time reduce the height of the fixing frame 200, the strength of the fixing frame 200 can be supplemented by the first connecting member 400.

[0051] For example, the first connector 400 is configured as a slat. The recessed platform 214 is disposed on the side of the fixing frame 200 that is close to each other. The end of the first connector 400 abuts against the side wall of the recessed platform 214 to cooperate with the subsequent fixing member 210 to fix the phase shifter 100 and prevent it from falling off.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting bracket 200 includes a support member and a fixing member 210. The fixing member 210 and the support member are detachably connected and form a clamping space 240. The phase shifter 100 is clamped in the clamping space 240. The support member has a first slot 231. At least part of the bottom of the phase shifter 100 is elastically clamped in the first slot 231. The fixing member 210 has a second slot 211. At least part of the top of the phase shifter 100 is elastically clamped in the second slot 211. Both the first slot 231 and the second slot 211 extend along the length direction of the phase shifter 100.

[0053] In these embodiments, the design of the mounting bracket 200 is further refined. The mounting bracket 200 consists of two parts: a support member and a fixing member 210. The two parts are detachably connected to form a clamping space 240 for securely clamping the phase shifter 100. The following are the main features of this design:

[0054] The support has a first slot 231 in which at least part of the bottom of the phase shifter 100 is elastically engaged. This design allows the phase shifter 100 to be supported in its length direction and, due to the elastic engagement, can accommodate a certain degree of dimensional variation while ensuring the stability of the installation.

[0055] For example, the carrier is a plastic part with a certain degree of elasticity, which can ensure the clamping strength between the first slot 231 and the phase shifter 100. Of course, the carrier can also be a plastic part with elasticity only in the first slot 231 part; or the carrier can be a clamping part, such as a two-finger gripper, a swing gripper, etc.

[0056] For example, in this embodiment, the bottom of the phase shifter 100 is completely held in the first slot 231, increasing the contact support area and improving stability.

[0057] The fastener 210 has a second slot 211 in which at least part of the top of the phase shifter 100 is elastically held. This not only provides additional positioning support for the phase shifter 100, but also ensures the stability of the entire assembly in the vertical direction.

[0058] For example, in this embodiment, the top of the phase shifter 100 has a protrusion that is held in the second slot 211, which can reduce the overall weight.

[0059] The clamping space 240 formed by the carrier and the fixing member 210 allows the phase shifter 100 to be securely clamped within it. This design facilitates the installation and maintenance of the phase shifter 100 and improves the overall structural stability. Furthermore, this structure allows the carrier to be pre-installed in a preset position on the reflector, then the phase shifter 100 to the feed line to be connected, and finally the phase shifter 100 to be placed in the first slot 231 and clamped by the fixing member 210. The second slot 211 and the first slot 231 provide lateral restraint to the phase shifter 100, reducing the probability of the phase shifter 100 falling off.

[0060] For ease of understanding, the first slot 231 and the second slot 211 are defined as follows: Both the first slot 231 and the second slot 211 extend along the length of the phase shifter 100, ensuring that the phase shifter 100 is uniformly supported and positioned along its entire length. This design helps reduce the risk of deformation or damage to the phase shifter 100 due to localized stress concentration, and also facilitates the adjustment and calibration of the phase shifter 100's position, ensuring its operational performance.

[0061] like Figure 2 As shown, in some embodiments, the first connector 400 and the fixing member 210 abut against each other, and the second slot 211 is disposed at the part where the fixing member 210 and the first connector 400 abut against each other.

[0062] In these embodiments, the mating relationship between the first connector 400 and the fixing member 210 is further optimized, and the stability and functionality of the overall structure are enhanced by placing the second slot 211 at the part where the fixing member 210 and the first connector 400 abut. The direct abutment between the first connector 400 and the fixing member 210 ensures a secure connection between the two and reduces shaking or displacement problems caused by loosening or gaps.

[0063] Furthermore, through contact, the first connector 400 can effectively transfer external forces (such as vibration or external impact) to the fastener 210, thereby dispersing stress and improving the vibration resistance of the overall structure.

[0064] The second slot 211 is located at the part where the fixing member 210 abuts against the first connector 400. This design cleverly utilizes the contact area between the fixing member 210 and the first connector 400, so that the second slot 211 can not only position and support the phase shifter 100, but also further enhance its stability through the abutment of the first connector 400.

[0065] In other words, the position of the second slot 211 fully utilizes the tight fit between the first connector 400 and the fixing member 210, further enhancing the clamping effect of the phase shifter 100, especially providing a more stable positioning at the top of the phase shifter 100. This design effectively reduces the offset or shaking of the phase shifter 100 during operation due to external vibrations or other interference factors. Furthermore, the abutting relationship between the first connector 400 and the fixing member 210, combined with the placement of the second slot 211, enhances the rigidity of the entire mounting assembly. This not only helps maintain the precise position of the phase shifter 100 but also reduces structural deformation caused by long-term use or changes in the external environment.

[0066] For example, the first connector 400 is configured as a rigid component, such as a hard non-metallic component, a composite material component, etc.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the carrier further includes a base 230 and an adjustment portion 220. The bottom end of the base 230 and the adjustment portion 220 are detachably connected, and the top end of the base 230 and the fixing member 210 are detachably connected. The base 230 is provided with a first slot 231, and the adjustment portion 220 is located on one side of the first slot 231. A clamping space 240 is formed between the fixing member 210, the adjustment portion 220 and the base 230.

[0068] In these embodiments, the carrier is further refined into two parts: a base 230 and an adjustment part 220, providing greater flexibility and adjustability to accommodate the installation requirements of phase shifters 100 of different sizes or types.

[0069] The bottom end of the base 230 is detachably connected to the adjustment part 220. The top end of the base 230 is detachably connected to the fixing member 210. A first slot 231 is provided on the base 230 for elastically holding the bottom of the phase shifter 100.

[0070] The adjustment part 220 is located on one side of the first slot 231, and its design allows the size of the clamping space 240 to be adjusted as needed. The clamping space 240 is formed by the adjustment part 220, the fixing member 210 and the base 230, ensuring that the phase shifter 100 can be securely clamped.

[0071] By replacing the adjustment section 220 with different height dimensions, the size of the clamping space 240 can be adjusted according to actual needs, thereby accommodating phase shifters 100 of different sizes or shapes. This increases the application range and flexibility of the entire mounting assembly.

[0072] Furthermore, since the base 230 is lower on the side away from the adjustment member, i.e., it has a side opening, it is convenient for the phase shifter 100 to be connected to the feeder line first and then installed into the first slot 231, thereby reducing the length of the feeder line.

[0073] For example, the adjustment part 220 is at least one support column, and both ends of the support column are provided with threaded holes to be connected to the base 230 and the fastener 210 by screws or bolts, respectively.

[0074] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the mounting assembly further includes a second connector 300, the mounting bracket 200 is detachably mounted on the second connector 300, the second connector 300 and the reflector are detachably connected, and a clearance space 320 is formed in the middle of the end of the second connector 300 near the reflector.

[0075] In these embodiments, the mounting assembly further incorporates a second connector 300 to increase the flexibility and adaptability of the overall structure.

[0076] The mounting bracket 200 is detachably mounted on the second connector 300, which provides additional support and positioning for the mounting bracket 200, while allowing for adjustment or replacement as needed.

[0077] The second connector 300 is also detachably connected to the reflector, facilitating installation, adjustment, and maintenance. Notably, the end of the second connector 300 near the reflector has a recessed center, forming a clearance space 320. This clearance space 320 is likely designed to avoid certain components (such as oscillators, other electronic components, etc.) to prevent physical interference or damage. In the absence of interfering components, the second connector 300 can be omitted. In other words, the introduction of the second connector 300 enhances the modularity of the entire mounting assembly, making the connections between various parts (such as the mounting bracket 200 and the reflector) more flexible and allowing for customization and adjustment according to the needs of different application scenarios.

[0078] Furthermore, the second connector 300 serves as a support point for the fixed frame 200, and together with the first connector 400, it further improves the stability of the entire structure and reduces the risk of the phase shifter 100 shifting or being damaged due to external factors (such as vibration or collision).

[0079] like Figure 2 and Figure 3 As shown, in some embodiments, the second connector 300 includes a main body 310 and at least two support portions 330. The support portions 330 are detachably provided at both ends of the main body 310. The support portions 330 and the reflector are detachably connected. An clearance space 320 is formed between the support portions 330 and the end of the main body 310 near the reflector. The fixing bracket 200 is detachably provided on the end of the main body 310 away from the reflector.

[0080] In these embodiments, the main body 310 is the core part of the second connector 300, and its end facing away from the reflector is used for detachably mounting the fixing frame 200. At least two support portions 330 are provided at each end of the main body 310, and these support portions 330 are also detachably connected to the reflector. A clearance space 320 is formed between the support portions 330 and the end of the main body 310 near the reflector. This design aims to avoid physical interference with other components (such as oscillators, other electronic components, etc.).

[0081] Since both the support unit 330 and the main body 310 can be adjusted or replaced according to actual needs, this modular design greatly improves the system's adaptability to different application scenarios. Whether facing tight space constraints or complex environmental conditions, a suitable solution can be found. For example, replacing the support unit 330 with one of different heights can raise the main body 310, creating a higher clearance space 320 to accommodate the oscillator heights on different reflectors.

[0082] For example, the support part 330 is a swivel buckle, which is fixed to the reflector by rotation. The support part 330 is connected to the main body 310 by screws.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the fixing frame 200 has a third plug-in body and a fourth plug-in body, and the main body 310 has a third plug-in groove 340 and a fourth plug-in groove 350. The third plug-in body and the fourth plug-in body are spaced apart, and the third plug-in groove 340 and the fourth plug-in groove 350 are spaced apart. The third plug-in body passes through the third plug-in groove 340 to form a positioning fit, and the fourth plug-in body passes through the fourth plug-in groove 350 to form a positioning fit.

[0084] In these embodiments, the connection between the mounting bracket 200 and the second connector 300 (body 310 portion) adopts a plug-in mating method to further enhance the stability and accuracy of the mounting components.

[0085] The mounting bracket 200 has a third and a fourth connector, which are spaced apart. This design ensures that the mounting bracket 200 can be securely connected to the main body 310 of the second connector 300 and provides necessary support. The main body 310 has a third and a fourth connector slot 340, which are also spaced apart.

[0086] The third connector passes through the third connector slot 340 to form a positioning fit, while the fourth connector passes through the fourth connector slot 350 to form a positioning fit. In this way, the fixing bracket 200 can be precisely installed on the main body 310, ensuring the accuracy of the position.

[0087] The tight fit between the connector and the slot not only provides physical support but also enhances the rigidity of the overall structure, reducing the risk of phase shifter 100 shifting or shaking due to external vibration or other factors.

[0088] The phase-spaced connector and slot design helps to precisely control the position of the mounting bracket 200 relative to the main body 310, thereby ensuring that the distance between a pair of phase shifters 100 remains consistent, reducing phase error and improving system performance.

[0089] Furthermore, the clear positioning mechanism simplifies the assembly process, making installation and maintenance more convenient and efficient. Operators can quickly and accurately connect the mounting bracket 200 to the main body 310, improving work efficiency.

[0090] For example, the third and fourth connectors are cylinders, the third and fourth connector slots 340 and 350 are circular holes, the third connector and the third connector slot 340 are either clearance or interference fit, and the fourth connector and the fourth connector slot 350 are either clearance or interference fit.

[0091] In some embodiments, this application also provides an antenna that includes any of the mounting components described in the above embodiments.

[0092] Since the mounting assembly of the phase shifter 100 has the aforementioned technical effects, the antenna including the mounting assembly of the phase shifter 100 should have the same technical effects, which will not be elaborated here.

[0093] For example, the antenna can be a multi-band base station antenna, a massive MIMO antenna, a dual-polarized antenna, a miniaturized / concealed antenna, or a high-precision satellite communication antenna, etc.

[0094] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
