[0020] Reference Figures 1-6The base station antenna provided by the present invention includes an antenna body 100, an RRU 200, a cover plate 300, a jumper 400, a connector 500, and a fixing assembly 600. The antenna body 100 has a recessed mounting groove on its back side. The RRU 200 is mounted on the back side of the antenna body 100. The cover plate 300 covers the opening of the mounting groove and can be detachably fastened with bolts. One end of the jumper 400 extends into the antenna body 100 and is directly connected to the feed network. The other end passes through a through hole 310 on the cover plate 300 and extends to the outside of the antenna body 100. The connector 500 is crimped onto the extended end of the jumper 400 and can mate with the corresponding connector on the RRU 200. The fixing assembly 600 is assembled between the through hole 310 and the jumper 400 to fix the jumper 400 to the cover plate 300 and simultaneously seal the through hole 310.

[0021] Reference Figures 1-6 In some embodiments, the cover plate 300 is made of die-cast aluminum alloy, which takes into account both structural strength and lightweight performance, and can be adapted to the use environment of outdoor base stations. The outer side of the cover plate 300 is provided with a recessed wiring groove 320, the side wall of the wiring groove 320 is arranged at an angle, and the through hole 310 is formed on the side wall of the wiring groove 320. The inner diameter of the through hole 310 is larger than the outer diameter of the connector 500, so that the jumper 400 with the connector 500 can pass directly from the inside of the cover plate 300 to the outside, without the need to pre-disassemble the connector 500 and the jumper 400 during the assembly process.

[0022] Reference Figures 1-6 In some embodiments, the jumper 400 serves as the main feed cable of the antenna, with one end connected to the feed network inside the antenna body 100 by welding or crimping. The signal can be directly transmitted outward through the jumper 400 and the connector 500. The jumper 400 can be a single coaxial cable structure or a structure of two or more parallel cables. The corresponding dimensions of the fixing component 600 can be adapted and adjusted according to the number and specifications of the cables.

[0023] Reference Figures 1-6 In some embodiments, the fixing component 600 includes a fixing seat 610, a waterproof rubber plug 620, a waterproof rubber ring 630, an inner pressure plate 640, an outer pressure plate 650, and a plurality of bolts 660. The fixing seat 610 is a hollow cylindrical structure that passes through the through hole 310, and its axis is consistent with the axis of the through hole 310. The waterproof rubber plug 620 fills the internal cavity of the fixing seat 610, and the jumper wire 400 passes through the inner hole of the waterproof rubber plug 620. The outer end of the fixing seat 610 is provided with an external thread, and a cap nut 680 is threadedly connected to it. When the cap nut 680 is tightened, the waterproof rubber plug 620 can be squeezed into the fixing seat 610, causing the waterproof rubber plug 620 to undergo radial deformation and hug the outer wall of the jumper wire 400, filling the gap between the jumper wire 400 and the fixing seat 610.

[0024] Furthermore, the inner end of the mounting base 610 is also provided with an external thread, and an inner nut 670 is threadedly connected to it. The inner pressure plate 640 is sleeved on the inner end of the mounting base 610. When the inner nut 670 is tightened, it can abut against the inner surface of the inner pressure plate 640, so that the inner pressure plate 640 and the mounting base 610 are assembled as one unit. The waterproof rubber ring 630 is set between the inner surface of the cover plate 300 and the inner pressure plate 640, and the outer pressure plate 650 abuts against the outer surface of the cover plate 300. The bolt 660 passes through the outer side of the outer pressure plate 650, passes through the outer pressure plate 650, the cover plate 300, and the waterproof rubber ring 630 in sequence, and then engages with the threaded hole on the inner pressure plate 640. When the bolt 660 is tightened, the outer pressure plate 650 and the inner pressure plate 640 clamp the cover plate 300 from both sides, and at the same time, the waterproof rubber ring 630 is squeezed to deform, filling the assembly gap around the through hole 310 and preventing external moisture and dust from entering the antenna.

[0025] Furthermore, the inner pressure plate 640, the outer pressure plate 650, and the waterproof rubber ring 630 can be configured to be square, round, oval, or other shapes that are compatible with the through hole 310, all of which can cover the surrounding area of ​​the through hole 310 to achieve the effect of sealing and fixing; the fixing base 610, the inner pressure plate 640, and the outer pressure plate 650 can be made of engineering plastic or metal, and the waterproof rubber plug 620 and the waterproof rubber ring 630 are made of silicone rubber, which has good elasticity and weather resistance.

[0026] Reference Figures 1-6 In some embodiments, the wiring slot 320 is constructed with a first slot 321 near the via 310 and a second slot 322 away from the via 310. The depth of the first slot 321 is greater than that of the second slot 322. The latch 700 is disposed in the first slot 321. When the connector 500 is latched on the latch 700, the head end of the connector 500 is located in the first slot 321 and the tail end is located in the second slot 322. This can accommodate the large outer diameter of the head end and the small outer diameter of the tail end of the connector 500, reducing the encroachment on the internal space of the antenna body 100. Furthermore, the latch 700 is fixed in the first slot 321 by bolts.

[0027] Reference Figures 1-6 In some embodiments, the depth of the second slot 322 gradually decreases from the end near the first slot 321 to the end away from the first slot 321, so that the bottom of the wiring slot 320 forms a gentle slope, which can accommodate the bending of the jumper 400 and reduce the damage caused by bending of the jumper; furthermore, the connection between the first slot 321 and the second slot 322 is inclined to avoid the accumulation of rainwater in the first slot 321 and the second slot 322.

[0028] When the antenna is in the state of being shipped, transported or not connected to RRU 200, the connector 500 can be fixed on the buckle 700, and the jumper 400 can be naturally stored along the slope of the wiring groove 320 without additional binding or protection. When in use, the connector 500 can be removed from the buckle 700 and directly connected to the RRU 200 on the back of the antenna body 100, which can shorten the effective length of the jumper 400.

[0029] Based on the above structure, the specific working principle of this base station antenna will be explained in detail below: During assembly, the fixing component 600 is first pre-installed in the corresponding position of the jumper 400. Then, the end of the jumper 400 with the connector 500 is passed from the inside of the cover plate 300 through the through hole 310 to the outside. Subsequently, the inner pressure plate 640, the waterproof rubber ring 630, and the outer pressure plate 650 are fastened to the cover plate 300 with bolts 660, thus completing the pre-assembly of the jumper 400 and the cover plate 300. The pre-assembled cover plate 300 can be connected to the antenna body 100 during the antenna production and debugging stage. The jumper 400, as the main feed line, directly participates in the antenna debugging and testing without the need to repeatedly disassemble the feed line and the internal connection of the antenna. When the antenna is finally packaged, the cover plate 300 is fastened to the assembly slot of the antenna body 100 to complete the overall assembly.

[0030] The advantages of this invention are: the above structure eliminates the need for a pair of male and female connectors, reducing costs and signal loss; the jumper connector can be directly passed through the cover plate and can participate in antenna production and debugging; it has both fixing and waterproof and dustproof functions, is easy to assemble, and also optimizes the jumper length, improving the convenience of production and use.

[0031] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
