Description

Technical Field

[0001] This utility model belongs to the field of mobile communication technology, specifically relating to a communication clamping component and an antenna assembly configured with the communication clamping component. Background Technology

[0002] In the field of communications, base station antenna technology is rapidly developing towards high spectral efficiency and multi-band integration. To meet the needs of 5G and future communication systems, electrically tunable base station antennas need to integrate multiple frequency bands, and their internal structures are increasingly trending towards miniaturization and highly integrated designs. Multi-band integrated electrically tunable antennas, as the current mainstream solution, typically require 6-10 or even more phase shifters to achieve beamforming and dynamic control, resulting in an extremely compact internal antenna layout and significantly increased cable routing complexity. Against this backdrop, the spatial layout of phase shifters has become a key factor in optimizing antenna performance and improving integration—a well-designed phase shifter position can not only improve the arrangement of internal components but also reserve more space for RF modules, heat dissipation systems, etc., and effectively improve cable routing efficiency. However, existing phase shifter layout schemes have significant drawbacks:

[0003] (1) Horizontal layout occupies a lot of space: Currently, most phase shifters are fixed to the reflector surface in a horizontal arrangement. This layout requires continuous horizontal space to be reserved for the phase shifters. Since the height of phase shifters in different frequency bands varies significantly (e.g., the volume of low frequency band phase shifters is large), the horizontal layout needs to be adapted to the installation requirements of different heights, resulting in low space utilization of the reflector and further exacerbating the contradiction in the internal layout of the antenna.

[0004] (2) Poor versatility of fixing devices: Traditional phase shifter fixing devices adopt a "one-to-one" customized design, that is, each height of phase shifter requires a special bracket or clip. This not only increases the variety of molds and production costs, but also leads to insufficient flexibility in antenna assembly, making it difficult to adapt to the dynamic configuration requirements of multi-band and multi-specification phase shifters, which seriously restricts the scalability and maintenance efficiency of antenna products.

[0005] Therefore, how to break through the physical space limitations of the existing phase shifter layout and solve the problem of poor versatility of fixed devices has become a technical bottleneck for improving the integration and maintainability of electrically tunable antennas. There is an urgent need for a new phase shifter layout scheme that combines spatial adaptability and structural versatility. Utility Model Content

[0007] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0008] One of the purposes of this utility model is to provide a clamping member for a communication device, including a first clamping structure and a second clamping structure. The first clamping structure has a first clamping groove, and the second clamping structure has a second clamping groove. The first clamping structure and the second clamping structure are movably connected so that the first clamping groove and the second clamping groove surround each other to form a clamping hole with an adjustable diameter. The clamping hole is suitable for clamping the metal cavity of the communication device.

[0009] In one embodiment, the first clamping structure includes a base and a pair of limiting arms disposed on both sides of the base, the base and the pair of limiting arms surrounding each other to form the first clamping groove, and the second clamping structure includes a top seat and a pair of plug-in arms disposed on both sides of the top seat, the top seat and the pair of plug-in arms surrounding each other to form the second clamping groove, and the pair of limiting arms respectively corresponding to and movably engaging with the pair of plug-in arms.

[0012] In one embodiment, a wire protection groove is provided on the bottom of the first clamping groove, and the wire protection groove is arranged along the axial direction of the metal cavity.

[0013] In one embodiment, a pair of wire protection grooves are provided on the bottom of the first clamping groove, and a limiting block is provided between the pair of wire protection grooves, the limiting block protruding toward the top seat.

[0014] In one embodiment, the bottom surface of the base is provided with a limiting slider and an elastic arm, the limiting slider and the elastic arm are respectively disposed at both ends of the bottom surface, the limiting slider is provided in a direction away from the top seat, and the elastic arm is provided with an elastic block.

[0015] In one embodiment, the base includes a bottom plate and a clamping plate arranged in parallel. The clamping plate forms the bottom of the first clamping groove. The bottom plate is disposed away from the top seat relative to the clamping plate. A telescopic structure is provided between the bottom plate and the clamping plate to adjust the distance between the bottom plate and the clamping plate.

[0016] In one embodiment, the bottom of the second clamping groove is provided with an elastic abutment portion, which protrudes toward the base.

[0017] In one embodiment, the first clamping structure is provided with at least two first clamping grooves, and the second clamping structure is provided with at least two second clamping grooves. The at least two first clamping grooves and the at least two second clamping grooves cooperate with each other to form a plurality of the aforementioned hoop holes.

[0019] Compared with the prior art, this utility model has many advantages, including but not limited to:

[0020] (1) The communication device clamping component of this utility model, by setting a first clamping structure and a second clamping structure and movably connecting the two to form a clamping hole with an adjustable aperture, can adapt to the metal cavity of communication devices with different circumferential dimensions. The clamping component of this utility model can clamp communication devices of various sizes, eliminating the need to equip different fixing devices for communication devices of different sizes, greatly improving the adaptability and versatility of fixing devices, and reducing production and maintenance costs.

[0021] (2) When the internal layout of a base station antenna is compact and the cable layout is intricate, it is particularly important to rationally arrange the spatial position of communication devices. The clamping part of this utility model can flexibly adjust the size of the clamping hole, making the layout of communication devices inside the antenna more flexible. According to the internal space of the antenna and the cable layout requirements, the appropriate position can be selected to install the communication devices, thereby improving the overall layout inside the antenna, freeing up more space for integrating more components, and improving the utilization rate of the internal space of the antenna.

[0022] (3) Since the clamping component of this utility model can clamp communication devices with different circumferential dimensions, the installation position of the communication devices inside the antenna is more flexible, which provides more space and convenience for coaxial cable wiring. When laying out coaxial cables, the position of communication devices can be reasonably arranged according to the direction and length of the coaxial cable, reducing the bending and crossing of the coaxial cable, thereby improving the efficiency of cable wiring, reducing the difficulty and cost of coaxial cable wiring, and also improving the reliability and stability of the antenna.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0036] This utility model provides a clamping component for a communication device. The clamping component clamps the metal cavity of the communication device through a clamping hole. The clamping component can adjust the size of its clamping hole so that the clamping component can be adapted to clamp metal cavities with different circumferential dimensions through the clamping hole. In other words, the clamping component can clamp communication devices with different circumferential dimensions.

[0037] The communication device can be a phase shifter, combiner, power divider, filter, etc., and the clamping member 100 is also fixedly disposed with the reflector 300, so that the clamping member 100 can fix the communication device on the reflector 300. In this embodiment, the present invention is described using a phase shifter 200 as an example of the communication device, but it should not be construed as a limitation of the present invention. The phase shifter 200 includes a cavity 210 and a phase shifting component, and the phase shifting component is installed in the cavity 210.

[0038] In a typical embodiment of this utility model, combined with Figures 1 to 4The clamping member 100 includes a first clamping structure 110 and a second clamping structure 120. The first clamping structure 110 has a first clamping groove 111, and the second clamping structure 120 has a second clamping groove 121. The first clamping structure 110 and the second clamping structure 120 are connected such that the first clamping groove 111 and the second clamping groove 121 surround each other to form a clamping hole 101. The clamping hole 101 can clamp one section of the cavity 210 in the longitudinal direction to limit the cavity 210 circumferentially.

[0039] Furthermore, the first clamping structure 110 is movably connected to the second clamping structure 120, so that the diameter of the hoop hole 101 formed by the first clamping groove 111 and the second clamping groove 121 is adjustable, so that the hoop hole 101 can clamp cavities 210 with different circumferential dimensions, thereby expanding the applicable range of the clamping member 100.

[0040] Specifically, the first clamping structure 110 includes a base 112 and a pair of limiting arms 113, which are respectively disposed on both sides of the base 112 to form the first clamping groove 111. The second clamping structure 120 includes a top seat 122 and a pair of plug-in arms 123, which are respectively disposed on both sides of the top seat 122 to form the second clamping groove 121. The opening of the first clamping groove 111 and the opening of the second clamping groove 121 face each other, so that the first clamping groove 111 and the second clamping groove 121 are connected to form the clamping groove. The limiting arms 113 are movably engaged with the corresponding plug-in arms 123, and the pair of limiting arms 113 are respectively movably engaged with the pair of plug-in arms 123, so that the diameter of the clamping hole 101 is adjustable, so that the clamping hole 101 can clamp cavities 210 with different circumferential dimensions.

[0041] Furthermore, the limiting arm 113 is provided with a snap-fit ​​portion 114, and the insertion arm 123 is provided with a mating portion. The mating portion is provided with multiple snap-fit ​​slots 124, which are arranged sequentially along the axial direction of the limiting arm 113. The snap-fit ​​portion 114 can snap into any one of the snap-fit ​​slots 124 in the mating portion, so that the limiting arm 113 and the insertion arm 123 are snapped and fixed. Because the multiple snap-fit ​​slots 124 are arranged sequentially along the axial direction of the limiting arm 113, the limiting arm 113 can snap into any one of the snap-fit ​​slots 124 along the axial direction of the insertion arm 123. The pair of limiting arms 113 are respectively movably snapped into the pair of insertion arms 123, thereby adjusting the diameter of the clamping hole 101 so that the clamping hole 101 can clamp cavities 210 with different circumferential dimensions, thus improving the applicability of the clamping member 100.

[0042] In one embodiment, the limiting arm 113 has an insertion channel 115, which is arranged along the axial direction of the limiting arm 113, and has an opening at the end of the limiting arm 113 away from the base 112. The locking part 114 is disposed within the insertion channel 115, and the locking part 114 is an elastic protrusion structure.

[0043] The insertion arm 123 is inserted into the insertion channel 115, allowing the locking part 114 to elastically engage with any of the slots 124 on the insertion arm 123 to adjust the size of the hole 101. Furthermore, the insertion channel 115 can circumferentially limit the insertion arm 123, and the locking part 114 engages with the slots 124 to axially limit the insertion arm 123, ensuring a stable connection between the insertion arm 123 and the limiting arm 113, thus maintaining the structural stability of the clamping member 100.

[0044] In a typical embodiment of this utility model, the base 112 includes a clamping plate 1121, which, together with the pair of limiting arms 113, forms the first clamping groove 111. A wire protection groove 1122 is provided on the bottom of the first clamping groove 111. It can be understood that the wire protection groove 1122 is formed on the clamping plate 1121. Combined with... Figure 5 A wiring groove 212 is provided on one side wall (referred to as bottom wall 211) of the cavity 210 of the phase shifter 200. The phase shifter 200 is electrically connected to an external communication device via a coaxial cable 400. The coaxial cable 400 is arranged in the wiring groove 212 to properly arrange the coaxial cable 400.

[0045] Combination Figures 1 to 5 When the clamping hole 101 clamps the cavity 210, the bottom wall 211 of the cavity 210 is positioned opposite to the clamping plate 1121 of the first clamping groove 111. The wiring groove 212 on the cavity 210 is aligned with the wire protection groove 1122 on the clamping plate 1121 to form a wiring hole. It is understood that the coaxial cable 400 is arranged in the wiring hole for further proper placement. In one embodiment, the cavity 210 is provided with multiple wiring grooves 212, and the bottom of the first clamping groove 111 is also provided with multiple wire protection grooves 1122. Each wiring groove 212 and a corresponding wire protection groove 1122 are arranged to form a wiring hole, and the multiple wiring grooves 212 cooperate with the multiple wire protection grooves 1122 to form multiple wiring holes.

[0046] In one embodiment, combined Figure 2 and Figure 5A limiting block 1123 is provided on the bottom of the first clamping groove 111, and the limiting block 1123 protrudes toward the top seat 122 of the second clamping structure 120; a limiting groove 213 is provided on the bottom wall 211 of the cavity 210, and the limiting block 1123 is inserted into the limiting groove 213 to limit the cavity 210 axially, and the hoop hole 101 limits the cavity 210 circumferentially, so that the clamping member 100 can stably clamp the cavity 210.

[0047] In a further embodiment, combined with Figure 2 The bottom of the first clamping groove 111 is provided with a pair of wire protection grooves 1122, which are parallel and spaced apart, and the limiting block 1123 is disposed between the pair of wire protection grooves 1122.

[0048] In one embodiment, combined Figure 4 The bottom of the second clamping groove 121 is provided with an elastic abutment portion 125, that is, the elastic abutment portion 125 is disposed on the top seat 122 of the second clamping structure 120, and the elastic abutment portion 125 protrudes towards the bottom of the first clamping groove 111. Figure 1 and Figure 4 One sidewall of the cavity 210 of the phase shifter 200 (referred to as the top wall 214) is disposed opposite to the bottom wall 211. When the clamping hole 101 clamps the cavity 210, the top wall 214 is disposed opposite to the elastic abutment portion 125, and the elastic abutment portion 125 elastically abuts against the top wall 214, causing the elastic abutment portion 125 to change from an extended state to a compressed state, so as to apply an elastic abutment force towards the bottom of the first clamping groove 111 to the top wall 214, so as to further elastically limit the cavity 210, so that the clamping member 100 can clamp the cavity 210. In this embodiment, it is recommended that the elastic abutment portion 125 be a spring sheet structure, but this should not be construed as a limitation of this utility model.

[0049] In a typical embodiment of this utility model, combined with Figure 1 The clamping member 100 is disposed on the reflector plate 300. Specifically, the base 112 of the first clamping structure 110 is disposed on the reflector plate 300. It can be understood that the phase shifter 200 is disposed on the reflector plate 300 via the clamping member 100.

[0050] Specifically, in combination Figure 3The base 112 further includes a base plate 1124, which is spaced apart from the clamping plate 1121. A limiting slider 116 is provided on the side of the base plate 1124 that faces the same direction as the bottom of the second clamping groove 121 (referred to as the bottom surface 1125). The limiting slider 116 includes a sliding plate 1161 and a limiting plate 1162. The sliding plate 1161 is connected to the bottom surface 1125, and the limiting plate 1162 is perpendicular to the sliding plate 1161. In the projection direction of the bottom surface 1125, the projected area of ​​the limiting plate 1162 is larger than the projected area of ​​the sliding plate 1161. That is to say, the sliding plate 1161 and the limiting plate 1162 are connected to form a T-shaped structure.

[0051] Combination Figure 6 The reflector 300 is provided with a limiting groove 310, which includes a first groove 311 and a second groove 312. The first groove 311 and the second groove 312 are connected, and the area of ​​the first groove 311 is larger than the area of ​​the second groove 312, so that the first groove 311 and the second groove 312 are connected to form a T-shaped structure.

[0052] Specifically, in combination Figure 3 and Figure 6 The clamping member 100 is disposed on the front surface 320 of the reflector 300. In the projection direction of the reflector 300, the projected area of ​​the first sliding groove 311 is greater than or equal to the projected area of ​​the limiting plate 1162, so that the limiting plate 1162 can pass through the reflector 300 through the first sliding groove 311. It can be understood that the limiting plate 1162 moves from the front surface 320 of the reflector 300 to the back surface of the reflector 300.

[0053] In the projection direction of the reflector 300, the projected area of ​​the second slide groove 312 is smaller than the projected area of ​​the limiting plate 1162, but the projected area of ​​the second slide groove 312 is greater than or equal to the projected area of ​​the sliding plate 1161. When the limiting plate 1162 moves to the opposite side of the reflector 300 via the first slide groove 311, a force can be applied to the limiting slider 116 toward the second slide groove 312, causing the sliding plate 1161 to enter the second slide groove 312, thereby limiting the limiting plate 1162 by the second slide groove 312, confining the limiting plate 1162 to the opposite side of the reflector 300, thereby limiting the base 112, and ensuring that the clamping member 100 is stably mounted on the reflector 300.

[0054] Combination Figure 3The limiting slider 116 is disposed at one end of the base plate 1124, and the other end of the base plate 1124 extends away from the limiting slider 116 to form an elastic arm 117. An elastic block 1171 is formed on the elastic arm 117. The elastic block 1171 protrudes relative to the elastic arm 117, and the elastic block 1171 and the limiting slider 116 protrude in the same direction.

[0055] Combination Figure 3 and Figure 6 The reflector 300 is provided with an elastic groove 313. When the sliding plate 1161 of the limiting slider 116 enters the second groove 312, the elastic block 1171 engages with the elastic groove 313 to limit the sliding plate 1161, so that the sliding plate 1161 cannot move relative to the second groove 312, so that the base 112 is further stably set on the reflector 300, and so that the clamping member 100 is stably set on the reflector 300.

[0056] In one embodiment, combined Figures 1 to 3 A telescopic structure is also provided between the base plate 1124 and the clamping plate 1121 of the base 112. This telescopic structure is used to adjust the distance between the base plate 1124 and the clamping plate 1121, thereby increasing the distance between the phase shifter 200 and the reflector 300. In this embodiment, the telescopic structure is recommended to be a telescopic plate 1126. The two ends of the telescopic plate 1126 are respectively connected to the clamping plate 1121 and the base 112. By setting the length of the telescopic plate 1126, the distance between the base plate 1124 and the clamping plate 1121 can be adjusted.

[0057] In another embodiment, the telescopic plate 1126 is a screw, the base plate 1124 and the clamping plate 1121 are separately disposed, and both the base plate 1124 and the clamping plate 1121 are provided with screw holes. The screw is simultaneously screwed into the screw holes on the base plate 1124 and the clamping plate 1121, and the distance between the base plate 1124 and the clamping plate 1121 is adjusted by the screw.

[0058] In one embodiment, combined Figures 7 to 9The clamping member 100 is provided with a plurality of clamping holes 101 arranged side by side. Each clamping hole 101 clamps one phase shifter 200, and the plurality of clamping holes 101 respectively clamp the plurality of phase shifters 200, so that the clamping member 100 can clamp the plurality of phase shifters 200 simultaneously. Specifically, the first clamping structure 110 is provided with a plurality of first clamping grooves 111, and the second clamping structure 120 is provided with a plurality of second clamping grooves 121. The first clamping grooves 111 and the second clamping grooves 121 are connected to each other to form clamping holes 101, and the plurality of first clamping grooves 111 are respectively connected to the plurality of second clamping grooves 121 to form a plurality of clamping holes 101.

[0059] This utility model also provides an antenna assembly 500, combined with... Figure 1 and Figure 9 The antenna assembly 500 includes a phase shifter 200, a reflector 300, and at least one clamping member 100 as described above. The clamping member 100 is located on the reflector 300 and clamps the cavity 210 of the phase shifter 200 through a clamping hole 101. The conversion relationship between the phase shifter 200, the reflector 300, and the clamping member 100 is described above and will not be repeated here for the sake of brevity.

[0060] In this embodiment, the antenna assembly 500 is provided with a plurality of clamping members 100, which are arranged sequentially along the axial direction of the cavity 210. The plurality of clamping members 100 simultaneously clamp the cavity 210, so that the phase shifter 200 can be stably disposed on the reflector 300.

[0061] For example, the antenna assembly 500 is provided with two clamping members 100, which are respectively disposed at both ends of the cavity 210 of the phase shifter 200. The two clamping members 100 cooperate to stably place the phase shifter 200 on the reflector 300.

[0062] In summary, the clamping member of this utility model has an adjustable hole diameter, which clamps metal cavities with different circumferential dimensions. The metal cavities are used as cavities for communication devices, so that the clamping member can be adapted to clamp communication devices with different circumferential dimensions.
