[0027] The following will Figures 1 to 7 further elaborate on this application in detail with reference to the attached

[0028] This application discloses a phase-shifting combiner.

[0029] Refer to Figures 1-7, the combined path coupler includes a coupler body 1, a protective top cover 2, a sealing module 3 and a positioning module 4; among them, both the coupler body 1 and the protective top cover 2 are configured as a rectangular-like structure similar to a rectangular body.

A circuit element 51 is arranged in the inner cavity of the coupler body 1, and an input connector 52 and an output connector 53 connected to the circuit element 51 are respectively arranged on both sides of the coupler body 1. The protective top cover 2 is arranged on the top of the coupler body 1 to protect the circuit element 51 in the inner cavity of the coupler body 1; the sealing module 3 is arranged between the protective top cover 2 and the coupler body 1, and the sealing structure 31 is used to seal and connect the coupler body 1 and the protective top cover 2, so that the coupler has good waterproof performance when applied to an outdoor installation environment, and tries to avoid water vapor entering the inner cavity of the coupler body 1 and causing the circuit element 51 to fail and stop working; the positioning module 4 can achieve positioning and alignment during the process of the sealing structure 31 sealing and connecting the coupler body 1 and the protective top cover 2, and improve the sealing connection effect.

[0030] The sealing module 3 specifically includes a sealing structure 31, a connecting structure 32 and a glue injection structure 33; among them, the sealing structure 31 is arranged between the protective top cover 2 and the coupler body 1 and forms an annular glue injection space. The connecting structure 32 is arranged between the protective top cover 2 and the coupler body 1, and the connecting structure 32 is used to tightly fit and lock the protective top cover 2 and the coupler body 1. The glue injection structure 33 is arranged on the protective top cover 2. The inside of the glue injection structure 33 is provided with sealant, and during the process of tightly fitting and locking the protective top cover 2 and the coupler body 1, the glue injection structure 33 fills the sealant into the glue injection space. The connecting structure 32 tightly fits and locks the protective top cover 2 and the coupler body 1, and during the tightly fitting and locking process, the glue injection structure 33 fills the reserved sealant between the protective top cover 2 and the coupler body 1, so that in addition to the sealing effect of the sealing structure 31 between the protective top cover 2 and the coupler body 1, the sealing effect of the solidified sealant is also increased. The double sealing effect enables the coupler to have good waterproof performance when applied to an outdoor installation environment, and tries to avoid water vapor entering the inner cavity of the coupler body 1 and causing the circuit element 51 to fail and stop working.

[0031] The sealing structure 31 specifically includes an inner sealing ring 311 and an outer sealing ring 312. Both the inner sealing ring 311 and the outer sealing ring 312 are in the structure of annular rubber rings. The difference is that the contour size of the outer sealing ring 312 is larger than that of the inner sealing ring 311, so that the inner sealing ring 311 and the outer sealing ring 312 are distributed inside and outside; among them, the inner sealing ring 311 is fixedly arranged in a groove reserved at the top of the combiner body 1 by an adhesive method. An inner sealing groove 313 adapted to be embedded with the inner sealing ring 311 is arranged on one side of the protective top cover 2 facing the combiner body 1. The outer sealing ring 312 is fixedly arranged in a groove reserved at the top of the combiner body 1. An outer sealing groove 314 adapted to be embedded with the outer sealing ring 312 is arranged on one side of the protective top cover 2 facing the combiner body 1; when the protective top cover 2 and the combiner body 1 are closed, the inner sealing ring 311 is embedded in the inner sealing groove 313, and the outer sealing ring 312 is embedded in the outer sealing groove 314, so as to form a sealing effect between the protective top cover 2 and the combiner body 1, enabling the combiner to have good waterproof performance when applied to an outdoor installation environment.

[0032] The connecting structure 32 specifically includes multiple groups of connecting mechanisms 321 and a fixing mechanism 322; among them, a flange portion 85 is fixedly arranged on the outer periphery of the side of the protective top cover 2 away from the combiner body 1, which is used to provide an installation basis for the connecting mechanism 321. There are four groups of connecting mechanisms 321, and the four groups of connecting mechanisms 321 are distributed on the flange portions 85 at the four corner positions of the protective top cover 2. And each group of connecting mechanisms 321 is movably arranged on the protective top cover 2. The fixing mechanism 322 is fixedly arranged on the outer periphery of the top of the combiner body 1, also forming a flange structure, and the connecting mechanism 321 is arranged in a threaded hole reserved by the fixing mechanism 322 through a threaded connection method.

[0033] Each set of connection mechanisms 321 specifically includes a rotating column 81, a hexagonal column 82, a connection part 83, and a synchronous pulley 84. Among them, since a flange part 85 is fixedly arranged on the outer periphery of the side of the protective top cover 2 away from the duplexer body 1, the rotating column 81 can be rotatably arranged on the flange part 85. The specific rotation method is that the rotating column 81 penetrates through the flange part 85. A limiting disc is arranged on the outer periphery of the rotating column 81, and a limiting circular groove adapted to the limiting disc is arranged on the flange part 85, so that the rotating column 81 rotates relative to the flange part 85. A knob groove with a cross structure is arranged at the top of the rotating column 81. The top of the hexagonal column 82 is fixedly arranged at the bottom of the rotating column 81. The connection part 83 is slidably sleeved on the bottom of the hexagonal column 82. The specific sliding method is that a hexagonal hole slidably adapted to the hexagonal column 82 is arranged in the center of the connection part 83, a limiting sliding groove is arranged on the inner periphery of the hexagonal hole, and a limiting sliding block is arranged at the bottom of the hexagonal column 82, and the limiting sliding block is slidably arranged in the limiting sliding groove, so that synchronous rotation can be carried out between the rotating column 81 and the connection part 83, relative sliding can be carried out between the rotating column 81 and the connection part 83 at the same time, and the rotating column 81 and the connection part 83 can be kept connected and will not be separated from each other at the same time. An external thread is arranged on the outer periphery of the connection part 83, so that the connection mechanism 321 can be arranged in a threaded hole reserved by the fixing mechanism 322 through a threaded connection method, that is, the connection part 83 is threadedly connected to the fixing mechanism 322. The synchronous pulley 84 is fixedly arranged on the rotating column 81, and a synchronous belt 86 is detachably connected between the four groups of synchronous pulleys 84. The synchronous pulley 84 is a toothed belt pulley, and the synchronous belt 86 is a toothed belt. The toothed belt is connected between the four groups of synchronous pulleys 84 by using the slightly stretchable performance of the toothed belt, or the toothed belt is removed from the four groups of synchronous pulleys 84 by using the slightly stretchable performance of the toothed belt, which realizes the detachable connection between the four groups of synchronous pulleys 84 and the synchronous belt 86.

[0034] The glue injection structure 33 specifically includes an inner compression ring 331 and an outer compression ring 332. Both the inner compression ring 331 and the outer compression ring 332 are annular rubber ring structures. The difference is that the contour size of the outer compression ring 332 is larger than that of the inner compression ring 331, so that the inner compression ring 331 and the outer compression ring 332 are distributed inside and outside, and the position of the inner compression ring 331 corresponds to the inner sealing groove 313, and the position of the outer compression ring 332 corresponds to the outer sealing groove 314; that is, the inner compression ring 331 is movably embedded in the inner sealing groove 313, and an inner extrusion cavity for filling sealant is formed between the inner compression ring 331 and the inner sealing groove 313. The outer compression ring 332 is movably embedded in the outer sealing groove 314, and an outer extrusion cavity for filling sealant is formed between the outer compression ring 332 and the outer sealing groove 314; first, an appropriate amount of sealant is filled in the inner sealing groove 313 and the outer sealing groove 314, then the inner compression ring 331 is embedded in the inner sealing groove 313, and then the outer compression ring 332 is embedded in the outer sealing groove 314, so that the sealant reserved in the inner extrusion cavity and the outer extrusion cavity can be respectively extruded through the inner compression ring 331 and the outer compression ring 332; on the side of the protective top cover 2 facing the combiner body 1, there is an inwardly concave upper semi-circular groove 61. The upper semi-circular groove 61 is located between the inner sealing groove 313 and the outer sealing groove 314. On the side of the combiner body 1 facing the protective top cover 2, there is an inwardly concave lower semi-circular groove 62. The lower semi-circular groove 62 is located between the inner sealing ring 311 and the outer sealing ring 312. When the upper semi-circular groove 61 and the lower semi-circular groove 62 are closed together, the above-mentioned glue injection space can be jointly formed. There are glue inlet channels 63 connecting the inner extrusion cavity and the outer extrusion cavity with the upper semi-circular groove 61, and there is a glue outlet channel 64 connecting the middle part of the threaded hole of the fixing mechanism 322 with the lower semi-circular groove 62.

[0035] The positioning module 4 specifically includes four groups of positioning posts 41. The four groups of positioning posts 41 are distributed at the four corner positions of the combiner body 1. The four groups of positioning posts 41 are all fixedly arranged on the combiner body 1. Positioning grooves 42 adapted to be embedded with the inner sealing ring 311 are provided at the four corner positions of the protective top cover 2.

[0036] In this embodiment, reference rings 7 are provided in both the outer sealing groove 314 and the inner sealing groove 313. On the one hand, the amount of sealant in the outer sealing groove 314 and the inner sealing groove 313 is judged by the position of the reference rings 7. When an inner extrusion cavity is formed between the inner compression ring 331 and the inner sealing groove 313 and an outer extrusion cavity is formed between the outer compression ring 332 and the outer sealing groove 314, the two reference rings 7 respectively abut against the inner compression ring 331 and the outer compression ring 332, forming a temporary fixation for the inner compression ring 331 and the outer compression ring 332, and trying to prevent the inner compression ring 331 and the outer compression ring 332 from detaching from the protective top cover 2 and being lost during the installation process; wherein, the sum of the volumes of the outer extrusion cavity and the inner extrusion cavity is greater than the sum of the volumes of the glue injection space, the glue inlet channels 63 and the glue outlet channel 64.

[0037] In this embodiment, the pitch of the external thread of the connecting mechanism 321 is 1.0 - 1.5 mm, specifically 1.2 mm, and the clearance between the external thread and the threaded hole is 0.05 - 0.10 mm, specifically 0.06 mm. The aperture of the glue outlet channel 64 connected to the middle of the threaded hole at the connection with the threaded hole is 1.0 - 1.5 mm, specifically 1.2 mm.

[0038] Implementation principle:

[0039] S1. Inject an appropriate amount of sealant into the outer seal groove 314 and the inner seal groove 313 of the protective top cover 2 according to the position of the reference ring 7.

[0040] S2. Actively embed the inner compression ring 331 into the inner seal groove 313 so that an inner extrusion cavity filled with sealant is formed between the inner compression ring 331 and the inner seal groove 313. Actively embed the outer compression ring 332 into the outer seal groove 314 so that an outer extrusion cavity filled with sealant is formed between the outer compression ring 332 and the outer seal groove 314. At this time, if the inner compression ring 331 and the outer compression ring 332 are extruded by an external force, the sealant reserved in the inner extrusion cavity and the outer extrusion cavity can be extruded respectively.

[0041] S3. Use the cooperation of the positioning post 41 and the positioning groove 42 to close and cover the protective top cover 2 on the combiner body 1 so that the inner sealing ring 311 is embedded in the inner seal groove 313 and the outer sealing ring 312 is embedded in the outer seal groove 314.

[0042] S4. Use the slightly stretchable performance of the synchronous belt 86 to connect it between the four synchronous wheels 84. Rotate the rotating column 81 to drive the connecting part 83 to be threadedly connected to the threaded hole, realizing the connection between the connecting mechanism 321 and the fixing mechanism 322, and also realizing the connection between the protective top cover 2 and the combiner body 1. During this process, the inner sealing ring 311 is embedded to push the inner compression ring 331 to extrude the sealant in the inner extrusion cavity, and the outer sealing ring 312 is embedded to push the outer compression ring 332 to extrude the sealant in the outer extrusion cavity. The sealant is first extruded through the glue inlet channel 63 into the area jointly formed by the inner sealing ring 311, the outer sealing ring 312, the protective top cover 2, and the combiner body 1 (including the upper semi-circular groove 61 and the lower semi-circular groove 62), and then the sealant is extruded into the threaded hole through the glue outlet channel 64.

[0043] S5. After waiting for the sealant to solidify, not only is the seal between the protective top cover 2 and the combiner body 1 achieved through the sealing ring, but also through the sealant, forming a double-sealing effect between the protective top cover 2 and the combiner body 1, enabling the combiner to have better waterproof performance when applied to an outdoor installation environment.

[0044] It is worth mentioning that in the above S4, since the sum of the volumes of the outer extrusion cavity and the inner extrusion cavity is greater than the sum of the volumes of the glue injection space, the glue inlet channel 63, and the glue outlet channel 64. When the area formed by the inner sealing ring 311, the outer sealing ring 312, the protective top cover 2, and the combiner body 1 (including the upper semi-circular groove 61 and the lower semi-circular groove 62) is continuously shrinking, the sealant is forced to penetrate into the connection gap between the inner sealing ring 311 and the inner sealing groove 313, and the connection gap between the outer sealing ring 312 and the outer sealing groove 314, thereby improving the sealing effect between the protective top cover 2 and the combiner body 1. The sealant is forced to penetrate into the mating gap between the external thread and the threaded hole, thereby improving the connection stability between the protective top cover 2 and the combiner body 1.

[0045] In addition, during the process of gradually screwing the external thread into the threaded hole, the sealant flowing out from the glue outlet channel 64 in the middle of the threaded hole can drive the sealant under the drive of the external thread, increasing the contact surface between the sealant and the threaded hole, thereby further improving the connection stability between the protective top cover 2 and the combiner body 1.

[0046] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
