[0029] DETAILED DESCRIPTION In order to enable the above and other objectives, features and advantages of the present application to be more clearly understood, the following will describe the present application in further detail. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0031] In the following description, many specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0032] The base station antenna is the most common infrastructure in the field of wireless communication, which is generally composed of a radome and electronic elements such as a vibrator unit installed inside the radome. The opening end of the radome needs to be sealed by an end cover. In order to ensure waterproof packaging of the base station antenna, there are two ways, one of which is to seal the gap between the upper end cover and the radome by pouring glue, which is not only complicated and not environmentally friendly, but also the upper end cover cannot be detached from the radome after the glue is cured, affecting the subsequent maintenance and disassembly. The other way is to set a sealing strip between the upper end cover and the radome, and seal the gap between the upper end cover and the radome through the sealing strip to achieve the purpose of waterproof. However, the sealing strip of this way not only has the risk of aging failure, but also has high cost.

[0033] Based on this, referring to Figures 1 to 8 The end cover connecting structure of the antenna provided by the embodiments of the present application includes a radome 1, an upper end cover 2 and a connecting frame 3. The radome 1 is a hollow structure and has an opening end 11 communicating with the hollow structure. The connecting frame 3 is located in the opening end 11, and the circumference of the connecting frame 3 is fixedly connected with the inner wall of the radome 1, that is, the connecting frame 3 is embedded in the opening end 11, and the circumferential side surface of the connecting frame 3 is fixedly connected with the inner wall of a section of the opening end 11 of the radome 1.

[0034] The upper end cover 2 is arranged on the opening end 11, and the top of the upper end cover 2 is clamped on the connecting frame 3. The upper end cover 2 is stably connected with the radome 1 through the connecting frame 3, which can effectively prevent rainwater from entering the inside of the antenna through the assembly gap between the upper end cover 2 and the radome 1. The use of glue sealing and sealing strip sealing is avoided, and the assembly is simple and environmentally friendly.

[0035] In some embodiments, as shown in Figure 3 and Figure 4 The upper end cover 2 includes a top plate 21, and the top plate 21 is provided with a clamping column 4 extending towards the connecting frame 3. The connecting frame 3 is provided with a buckle structure 5, and the clamping column 4 is clamped in the buckle structure 5. Not only the stable connection between the connecting frame 3 and the top plate 21 is realized, but also the assembly of the upper end cover 2 and the radome 1 is simple and fast.

[0036] In some embodiments, as shown in Figure 5 and Figure 6 The buckle structure 5 includes an arc-shaped plate 51 and a protrusion 52 formed on the arc-shaped plate 51, and the clamping column 4 is formed with a recess 41, and the protrusion 52 is clamped in the recess 41.

[0037] Preferably, two arc-shaped plates 51 are provided, two protrusions 52 on the two arc-shaped plates 51 are oppositely arranged, two recesses 41 are formed on the clamping column 4 and oppositely arranged, the two recesses 41 and the two protrusions 52 are one-to-one correspondingly arranged, and each protrusion 52 is clamped in one recess 41. When the clamping column 4 is inserted between the two arc-shaped plates 51, the gap between the two arc-shaped plates 51 is enlarged to allow the clamping column 4 to be inserted, and when the clamping column 4 is inserted in place, the protrusion 52 extends into the recess 41 to limit the clamping column 4 from being separated from the buckle structure 5, thereby achieving stable connection between the clamping column 4 and the buckle structure 5.

[0038] In some embodiments, the connecting frame 3 is formed with a groove 35 on the side away from the top plate 21, the connecting frame 3 is provided with a through hole 36 communicating with the groove 35, and the buckle structure 5 is arranged in the groove 35, and the clamping column 4 passes through the through hole 36 and is clamped in the buckle structure 5. The connecting frame 3 provided with the groove 35 structure not only reduces the weight, but also forms a space for conveniently arranging the buckle structure 5.

[0039] In some specific embodiments, the connecting frame 3 includes cross-connected longitudinal beams 33 and transverse beams 34, and the longitudinal beams 33 and the transverse beams 34 are in an integrated structure. The cross-connected longitudinal beams 33 and transverse beams 34 are simple to form and low in cost, and the integrated longitudinal beams 33 and transverse beams 34 are more stable in connection.

[0040] In some embodiments, as shown in Figure 5 and Figure 6 , the longitudinal beams 33 and the transverse beams 34 are formed with grooves 35 recessed toward the first surface 31 on the second surface 32 away from the top plate 21, the bottom of the groove 35 is provided with a through hole 36 for the clamping column 4 to pass through, the buckle structure 5 is arranged in the groove 35, and the clamping column 4 is inserted into the buckle structure 5 from the through hole 36. The longitudinal beams 33 and the transverse beams 34 provided with the groove 35 structure not only reduce the weight, but also form a space for conveniently arranging the buckle structure 5.

[0041] In some embodiments, the transverse beams 34 are provided with at least two, the at least two transverse beams 34 are arranged in parallel, the end faces of each transverse beam 34 at both ends along the length direction thereof are connected with the inner side wall of the radome 1, and the longitudinal beams 33 are connected with the inner side wall of the radome 1 at both ends along the length direction thereof. The connecting frame 3 supports the open end 11 through the transverse beams 34 and / or the longitudinal beams 33, avoids deformation of the open end 11 of the radome 1, and reduces deformation or even damage of the radome 1 in the process of transportation and stacking (as shown in Figure 8 ).

[0042] In some embodiments, as shown in Figure 1 , the longitudinal beams 33 or the transverse beams 34 are provided with threaded holes at both ends along the length direction thereof, and screws 6 are threadedly connected with the threaded holes through the side wall of the radome 1, so as to stably connect the end faces of the longitudinal beams 33 or the transverse beams 34 at both ends along the length direction thereof with the inner wall of the radome 1.

[0043] In some embodiments, such as Figure 2 As shown, the upper cover 2 also includes an annular surrounding plate 22, which surrounds the top plate 21. The annular surrounding plate 22 is located around the opening end 11, and the screw 6 is located within the space formed by the annular surrounding plate 22. The annular surrounding plate 22 can cover the screw 6. Compared with the commonly used fasteners of the upper cover 2 in related technologies, which are exposed, the annular surrounding plate 22 covering the screw 6 makes the overall appearance more aesthetically pleasing.

[0044] In some embodiments, such as Figure 7 As shown, the distance L between the bottom end face of the annular enclosure 22 and the top end face of the opening end 11 satisfies L≥30mm, which can effectively prevent rainwater from entering the antenna through the assembly gap between the upper end cover 2 and the antenna cover 1.
