[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figures 1 to 7 A radiation unit component comprises a mounting base 1, a feeding base plate 2, a radiation panel 3 and two feeding plates 4; the mounting base 1 comprises a cylindrical main body 11 and a plurality of clamping parts arranged on the inner circumference of the main body 11, the clamping part comprises two convex strips 12, and a clamping groove 13 is formed between the two convex strips 12 of the clamping part; the two feeding plates 4 are orthogonally arranged inside the mounting base 1, and the two side edges of the two feeding plates 4 are respectively arranged in the clamping groove 13; the radiation panel 3 is arranged on the top of the mounting base 1, the feeding base plate 2 is arranged on the bottom of the mounting base 1, the top end of the feeding plate 4 is connected to the radiation panel 3 for feeding, and the bottom end of the feeding plate 4 is connected to the feeding base plate 2 for feeding.

[0030] From the above description, it can be seen that the beneficial effect of the utility model is that the feeding plate 4 of the radiation unit assembly is assembled into the interior of the mounting base 1 by respectively snapping the edges on both sides into the slots 13 of the snap-fitting parts. Since the main body 11 of the mounting base 1 is cylindrical, a cavity for heat dissipation can be formed between two adjacent snap-fitting parts, which effectively improves the heat dissipation capacity of the radiation unit assembly and is beneficial to high-power operation of the radiation unit assembly.

[0031] Furthermore, at least one of the convex strips 12 of the clamping portion is provided with a limiting protrusion 121 protruding toward the clamping slot 13 , and the feeding sheet 4 is provided with a limiting notch 41 cooperating with the limiting protrusion 121 .

[0032] It can be seen from the above description that the cooperation between the limiting protrusion 121 and the limiting notch 41 can limit the relative position of the feeding plate 4 and the mounting seat 1 , which is beneficial to improving the assembly accuracy of the feeding plate 4 and the mounting seat 1 .

[0033] Furthermore, one end of the convex strip 12 away from the main body 11 is bent and extended in a direction away from the slot 13 .

[0034] It can be seen from the above description that the end of the two protrusions 12 of the clamping portion away from the main body 11 is away from the feeding plate 4, and it is not easy to scratch or scratch the feeding plate 4 during the assembly process.

[0035] Furthermore, the radiation panel 3 includes a substrate 31 and two pairs of dipole arms 32 , and each pair of dipole arms 32 is respectively arranged on the upper surface and the lower surface of the substrate 31 .

[0036] It can be seen from the above description that arranging each pair of dipole arms 32 on the upper surface and the lower surface of the substrate 31 respectively is beneficial to increasing the radiation bandwidth of the radiation unit assembly.

[0037] Furthermore, a protruding plug-in column 14 is provided on the top of the mounting base 1 , at least one elastic clamping arm 141 is provided on the side of the plug-in column 14 , and a first plug hole matching with the plug-in column 14 is provided on the radiating arm.

[0038] It can be seen from the above description that the assembly method of the radiation panel 3 and the mounting base 1 is simple and convenient, does not require the use of additional fasteners, and is not likely to cause the radiation panel 3 to bend or deform.

[0039] Furthermore, it also includes a debugging piece 5 , on which a second plug hole matching with the plug-in column 14 is provided, and the debugging piece 5 is arranged between the elastic clamp arm 141 and the radiation panel 3 .

[0040] It can be seen from the above description that the user can add or remove the debugging piece 5 according to actual use needs to adjust the standing wave and debug the performance of the radiation unit assembly.

[0041] Furthermore, a baffle 15 protruding upward is provided on the top of the mounting seat 1 .

[0042] It can be seen from the above description that the baffle 15 is used to resist foreign objects to prevent the foreign objects from squeezing or colliding the connection between the feeding plate 4 and the radiation arm, resulting in poor contact.

[0043] Furthermore, the mounting seat 1 is provided with a protruding fool-proof column 16 , and the radiation panel 3 is provided with a fool-proof hole 33 that matches the fool-proof column 16 .

[0044] It can be seen from the above description that the foolproofing column 16 cooperates with the foolproofing hole 33 to limit the relative angle between the radiation panel 3 and the mounting seat 1, which is beneficial to assemble the radiation panel 3 accurately and improve the assembly efficiency.

[0045] Furthermore, a plurality of assembly legs 17 are provided at the bottom of the outer wall of the mounting seat 1 , and one end of the plurality of assembly legs 17 away from the mounting seat 1 extends downward to form an insertion end, and a protruding block 171 is provided on the outer side surface of the insertion end.

[0046] From the above description, it can be seen that the assembly foot 17 is used to be inserted into the assembly hole of the reflector until the block 171 contacts the back of the reflector, so that the radiation unit assembly is plugged into the reflector to fix the radiation unit assembly on the reflector. The assembly process is convenient, which effectively reduces the number of parts of the base station antenna, improves the installation efficiency of the base station antenna, and is beneficial to the performance stability of the base station antenna.

[0047] Furthermore, a window is provided on the outer side surface of the insertion end, and a protruding elastic arm 172 is provided on the inner circumference surface of the window. The elastic arm 172 extends upward, and the block 171 is provided on the outer side surface of the elastic arm 172 .

[0048] It can be seen from the above description that when the assembly support foot 17 is plugged into the reflector, the elastic arm 172 can be elastically deformed so that the clamping block 171 can smoothly pass through the assembly hole of the reflector.

[0049] Please refer to Figures 1 to 7 , Embodiment 1 of the utility model is: a radiation unit assembly, comprising a mounting base 1, a feeding base plate 2, a radiation panel 3 and two feeding plates 4; the mounting base 1 comprises a cylindrical main body 11 and a plurality of clamping parts arranged on the inner circumference of the main body 11, the clamping part comprises two convex strips 12, and a clamping groove 13 is formed between the two convex strips 12 of the clamping part; the two feeding plates 4 are orthogonally arranged inside the mounting base 1, and the two side edges of the two feeding plates 4 are respectively arranged in the clamping groove 13; the radiation panel 3 is arranged on the top of the mounting base 1, the feeding base plate 2 is arranged on the bottom of the mounting base 1, the top end of the feeding plate 4 is connected to the radiation panel 3 for feeding, and the bottom end of the feeding plate 4 is connected to the feeding base plate 2 for feeding.

[0050] In this embodiment, the main body 11 of the mounting base 1 includes a base, a support platform arranged above the base, and a plurality of support arms for connecting the base and the support platform. The radiation panel 3 is detachably mounted on the support platform. The clamping portion is arranged in the base. The base is in the shape of a polygonal cylinder, and the number of the clamping portions is four, and the four clamping portions are evenly distributed around the circumference of the base. The two side edges of the two feeding plates 4 are respectively arranged in the card groove 13 of a clamping portion. It is easy to understand that since the main body 11 of the mounting base 1 is in the shape of a cylinder, a cavity for heat dissipation can be formed between two adjacent clamping portions, which effectively improves the heat dissipation capacity of the radiation unit assembly, which is beneficial to the high-power operation of the radiation unit assembly.

[0051] At least one convex strip 12 of the clamping portion is provided with a limiting protrusion 121 protruding into the clamping slot 13, and the feed sheet 4 is provided with a limiting notch 41 that cooperates with the limiting protrusion 121. Specifically, the feed sheet 4 is inserted upward from the bottom of the mounting seat 1 into the clamping slot 13, and a guiding inclined surface is provided at one end of the protrusion away from the convex strip 12, and the top of the guiding inclined surface is inclined in a direction away from the convex strip 12.

[0052] The end of the convex strip 12 away from the body 11 bends and extends away from the slot 13. It is easy to understand that the end of the two convex strips 12 of the clamping part away from the body 11 is away from the feed sheet 4, which is not easy to scratch or scratch the feed sheet 4 during assembly.

[0053] The radiation panel 3 includes a substrate 31 and two pairs of dipole arms 32. The two pairs of dipole arms 32 are arranged orthogonally. Each pair of dipole arms 32 is arranged on the upper surface and the lower surface of the substrate 31, respectively. The two pairs of dipole arms 32 correspond to the two polarizations of the radiation unit assembly. Specifically, the substrate 31 is made of FR-4 material, and the dipole arms 32 are made of copper material. The support platform of the mounting base 1 is provided with a downwardly concave groove 18 corresponding to the dipole arm 32 to facilitate heat dissipation and facilitate high-power operation of the radiation unit assembly.

[0054] A protruding plug-in column 14 is provided on the top of the support platform of the mounting base 1, and at least one elastic clamping arm 141 is provided on the side of the plug-in column 14. The top of the elastic clamping arm 141 is connected to the top of the plug-in column 14, and a first socket matching with the plug-in column 14 is provided on the radiating arm.

[0055] Optionally, the radiation unit assembly further includes a debugging piece 5, on which a second plug hole matching the plug-in column 14 is provided, and the debugging piece 5 is arranged between the elastic clamp arm 141 and the radiation panel 3. The user can add or remove the debugging piece 5 according to actual use needs to adjust the standing wave and debug the performance of the radiation unit assembly.

[0056] A baffle 15 protruding upward is provided on the top of the mounting base 1, and a through hole for the baffle 15 to pass through is provided on the radiation panel 3. Specifically, a protruding welding portion is provided on the top of the feed sheet 4, and a contact hole for plugging and matching with the welding portion is provided on the radiation arm. The maximum height of the baffle 15 is greater than the maximum height of the plug-in column 14 and the welding portion. The baffle 15 is used to resist foreign objects to prevent foreign objects from squeezing or colliding with the connection between the feed sheet 4 and the radiation arm, resulting in poor contact.

[0057] The mounting base 1 is provided with a protruding foolproof column 16, and the radiation panel 3 is provided with a foolproof hole 33 that matches the foolproof column 16. Specifically, the foolproof column 16 is cylindrical, and the foolproof hole 33 is set to be circular corresponding to the foolproof column 16. The number of the foolproof column 16 is one. In other embodiments, the foolproof column 16 can be set to be a prism, and the number of the foolproof column 16 can be set to be multiple.

[0058] A plurality of assembly legs 17 are provided at the bottom of the outer wall of the mounting seat 1. The plurality of assembly legs 17 extend downward from one end of the mounting seat 1 to form an insertion end. A protruding block 171 is provided on the outer side of the insertion end. Specifically, the assembly legs 17 are formed by extending downward from the bottom end of the base of the mounting seat 1. The number of assembly legs 17 is four. In order to facilitate the insertion end to pass through the assembly hole on the reflector, the width of the insertion end gradually decreases from one end close to the mounting seat 1 to the other end. A window is provided on the outer side of the insertion end. The window connects the inner side and the outer side of the insertion end. A protruding elastic arm 172 is provided on the inner circumference of the window. The elastic arm 172 is formed by protruding upward from the bottom surface of the notch. The elastic arm 172 extends upward, and a block 171 is provided on the outer side of the elastic arm 172. The bottom surface of the block 171 is set as an inclined surface to facilitate passing through the assembly hole of the reflector. The top of the elastic arm 172 extends upward to form a pressing portion 173. After the insertion end passes through the assembly hole of the reflector, the block 171 will abut against the inner side of the assembly hole of the reflector to prevent the insertion end from exiting the assembly hole of the reflector, and the pressing portion 173 is exposed outside the assembly hole. It is easy to understand that when the radiation unit assembly needs to be removed from the reflector, it is only necessary to apply pressure to the pressing portion 173 to make the elastic arm 172 bend inward and deform, so that the block 171 no longer abuts against the inner side of the assembly hole, and the insertion end can exit the assembly hole, thereby allowing the radiation unit assembly to be removed from the reflector.

[0059] To summarize, the feeding plate of the radiation unit assembly provided by the utility model is assembled into the interior of the mounting seat by respectively snapping the edges on both sides into the slots of the snap-in parts. Since the main body of the mounting seat is cylindrical, a cavity for heat dissipation can be formed between two adjacent snap-in parts, which effectively improves the heat dissipation capacity of the radiation unit assembly and is beneficial to high-power operation of the radiation unit assembly.
