Description

Technical Field

[0001] This utility model relates to an antenna, specifically a multi-port antenna, belonging to the field of antenna technology. Background Technology

[0002] An antenna is a converter used to transform guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves. It converts high-frequency alternating current (guided waves) into electromagnetic waves and radiates them into space; when receiving, it converts electromagnetic waves in space into high-frequency alternating current, realizing the connection between "wired circuits" and "wireless space".

[0003] An existing patent (publication number: CN217387549U) discloses a multi-port directional antenna. By optimizing the port layout and signal transmission path, a full-duplex operating system with both multiple input / multiple output functionality and high power capacity is constructed. This structure breaks through the performance bottleneck of traditional single-port or wired port designs, enabling efficient reception and synchronous transmission of multiple signals simultaneously. It effectively solves the technical problems of low transmission efficiency and limited power capacity of traditional directional antennas in scenarios involving parallel processing of multiple signals. This design not only significantly improves the signal processing capability, transmission rate, and stability of the multi-port directional antenna, but also enhances its adaptability and scalability in complex communication scenarios, significantly optimizing the antenna's overall performance and practical application value. In practical use, to achieve parallel operation of multiple working systems, multiple functional ports need to be configured to meet the independent transmission requirements of multiple signals. However, this leads to a corresponding increase in the number of connecting cables. During actual installation, commissioning, or equipment maintenance, multiple cables need to be plugged into the corresponding ports simultaneously. Due to factors such as installation space layout, cable routing planning, and operating space limitations, adjacent cables are prone to overlapping and interlocking. In severe cases, cable tangling and twisting may also occur. This not only increases the difficulty of cable plugging operations and reduces installation and commissioning efficiency, but also causes inconvenience to subsequent equipment inspection, cable maintenance, and troubleshooting. It may even cause interface damage or cable insulation layer damage due to forced pulling of cables, leading to potential safety hazards in equipment operation. Utility Model Content

[0004] This invention provides a multi-port antenna to solve the problems of increased cables, inconvenient connection and maintenance caused by multiple ports.

[0005] The present invention achieves the above objectives through the following technical solution: a multi-port antenna, including an antenna base station, wherein a splitter shell is fixedly installed on one side of the outer wall of the antenna base station, and a storage shell is fixedly installed at the bottom of the splitter shell, and a splitter groove is opened on the outer wall of the splitter shell, and a positioning mechanism is provided inside the splitter groove.

[0006] The positioning mechanism includes a rotating rod that extends out of the bottom of the storage shell. A bearing is rotatably connected to one end of the rotating rod that extends into the storage shell. A contact plate is fixedly installed at the top of the bearing, and a sealing layer is embedded at the top of the contact plate. A pass-out frame extends into one side of the inner side of the dividing groove, and a storage shell is fitted onto one end of the pass-out frame that extends into the inner side of the dividing shell. A flow hole is opened at the bottom of the inner side of the storage shell, and a pressing plate is slidably connected to one side of the inner side of the storage shell.

[0007] As a further improvement of this utility model: the inside of the through-frame is rotatably connected with abutting rollers, and the outer wall of the pressing plate is fitted with a spring.

[0008] As a further improvement of this utility model: the contact plate is bonded to the sealing layer, and a sliding structure is formed between the contact plate and the storage shell.

[0009] As a further improvement of this utility model: the storage shell communicates with the receiving shell through a flow hole, and the receiving shell and the pressing plate form a sliding structure.

[0010] As a further improvement of this utility model: a through groove is provided on the other side of the inner side of the dividing groove, and a limiting mechanism is provided inside the through groove.

[0011] As a further embodiment of this utility model: the limiting mechanism includes a limiting roller, which is rotatably connected inside the through groove. The dividing shell is fitted with a mounting frame inside the through groove on one side, and the inner wall of the mounting frame is rotatably connected with a force-bearing roller.

[0012] As a further improvement of this utility model: an installation ring is fixedly installed on one side of the force-bearing roller inside the mounting frame, and a soft bladder is fixedly installed on the outer wall of the installation ring.

[0013] As a further improvement of this utility model: a conveying pipeline is fixedly installed on the outer wall of the mounting frame, and a diversion pipe is fixedly installed at one end of the conveying pipeline.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device precisely aligns the cable tray with the antenna plug-in port, enabling orderly separation and limiting of cables after plugging in, avoiding cable entanglement and interference. With the help of hydraulic oil circulation inside the storage shell, the contact rollers on the pass-through frame elastically press the cable, which can effectively prevent the cable from loosening and shifting, and avoid damage to the cable sheath caused by rigid clamping. When the cable is subjected to external pulling, the rotational characteristics of the contact rollers and the elastic extension and contraction of the spring form a double buffer, which can reserve a safe pulling stroke. This not only prevents the cable from directly detaching from the plug-in port, but also buffers the pulling stress, reduces the risk of cable breakage, and significantly improves connection reliability and service life.

[0016] 2. This device uses limiting rollers to initially limit the cable, significantly reducing friction during external pulling and preventing wear on the cable sheath or damage to the internal core. Simultaneously, the cable tightly contacts the force-bearing rollers on the mounting frame, forming a bidirectional elastic clamping structure with the contact rollers, further enhancing the limiting effect. Under the continuous pushing of the contact plate, hydraulic oil is injected into the soft bladder fixed by the mounting ring through the delivery network and diversion pipe, achieving flexible clamping of the cable from all directions. Compared to rigid clamping, the soft bladder can accommodate cables of different diameters and avoids cable damage caused by stress concentration. It also significantly improves positioning stability, preventing cable displacement under vibration. For later maintenance, simply reverse the rotation rod to reset the contact plate; the suction generated during reset drives the hydraulic oil to automatically return. Operators can directly adjust and replace cables without disassembling the clamping structure or bolts, making operation convenient and efficient. This design avoids the drawbacks of traditional single clamping methods, such as unstable positioning and cumbersome bolt installation and removal, significantly reducing maintenance time and improving base station operation and maintenance efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, a multi-port antenna includes an antenna base station 1. A splitter housing 2 is fixedly installed on one side of the outer wall of the antenna base station 1. A storage housing 3 is fixedly installed at the bottom end of the splitter housing 2. A splitter groove 4 is formed on the outer wall of the splitter housing 2. A positioning mechanism 5 is provided inside the splitter groove 4. The positioning mechanism 5 includes a rotating rod 501, which extends out of the bottom end of the storage housing 3. A bearing 502 is rotatably connected to one end of the rotating rod 501 that extends into the storage housing 3. A contact plate 503 is fixedly installed at the top end of the bearing 502. A sealing layer 504 is embedded at the top end of the contact plate 503. A pass-out bracket 505 extends through one side of the inner wall of the splitter groove 4. A storage shell 506 is fitted onto one end of the bracket 505 that penetrates into the cable distribution shell 2. A flow hole 507 is provided at the bottom of the storage shell 506. A pressing plate 508 is slidably connected to one side of the storage shell 506 and is rotatably connected to a contact plate 503 via a bearing 502. This allows the contact plate 503 to push the hydraulic oil inside the storage shell 3 into the storage shell 506 through the flow hole 507. The sealing layer 504 improves the overall airtightness and facilitates the generation of pressure to allow the hydraulic oil to flow. When the hydraulic oil enters the storage shell 506, it will squeeze the pressing plate 508, generating a resistance force on the cable, thereby achieving a certain limiting effect.

[0026] Furthermore, the inside of the through-frame 505 is rotatably connected to an abutment roller 509, and the outer wall of the pressing plate 508 is fitted with a spring 510; the rotation of the abutment roller 509 and the elastic extension and contraction of the spring 510 can reserve some space for cable pulling, so as to prevent the cable from loosening directly with the port.

[0027] Furthermore, the contact plate 503 is bonded to the sealing layer 504, and a sliding structure is formed between the contact plate 503 and the storage shell 3; the sealing layer 504 improves the overall airtightness and facilitates the generation of pressure to allow hydraulic oil to flow.

[0028] Furthermore, the storage shell 3 is connected to the receiving shell 506 through the flow hole 507, and the receiving shell 506 and the pressing plate 508 form a sliding structure; through the flow hole 507, the hydraulic oil inside the storage shell 3 that is being squeezed can enter the receiving shell 506, thereby squeezing the pressing plate 508 to move.

[0029] Example 2

[0030] An improvement based on Embodiment 1: A through groove 6 is provided on the other side of the inside of the cable tray 4, and a limiting mechanism 7 is provided inside the through groove 6; when the abutting roller 509 abuts the cable and enters the through groove 6, it can contact the limiting mechanism 7.

[0031] Furthermore, the limiting mechanism 7 includes a limiting roller 701, which is rotatably connected inside the through groove 6. The cable splitter housing 2 is fitted with a mounting bracket 702 on one side of the through groove 6. The inner wall of the mounting bracket 702 is rotatably connected to a force-bearing roller 703. The limiting roller 701 provides initial clamping for the cable and prevents excessive friction from damaging the cable when subjected to external pulling.

[0032] Furthermore, an installation ring 704 is fixedly installed on one side of the force-bearing roller 703 inside the mounting bracket 702, and a soft bladder 705 is fixedly installed on the outer wall of the installation ring 704; the soft bladder 705 fixed by the installation ring 704 can clamp the cable from above and below when filled with hydraulic oil, thereby further improving the stability of positioning.

[0033] Furthermore, a delivery pipeline 706 is fixedly installed on the outer wall of the mounting bracket 702, and a diversion pipe 707 is fixedly installed at one end of the delivery pipeline 706; under the push of the hydraulic oil by the contact plate 503, the hydraulic oil can be delivered through the delivery pipeline 706 to the diversion pipe 707 and enter the soft bladder 705.

[0034] Working principle: The splitter shell 2 is fixedly connected to the antenna base station 1 by bolts. Its splitter groove 4 corresponds to the antenna plug-in port, which can realize orderly separation and limit the position after the cable is plugged in, avoid mutual interference between cables, and improve the convenience of later maintenance. After the cable is plugged in, the rotating rod 501 is turned. Utilizing its threaded engagement with the storage shell 3 and the rotational connection between the bearing 502 and the contact plate 503, the contact plate 503 is driven to squeeze the hydraulic oil inside the storage shell 3. The hydraulic oil is injected into the receiving shell 506 through the flow hole 507. The sealing layer 504 ensures the overall airtightness and provides pressure support for the smooth flow of hydraulic oil. After the hydraulic oil enters the receiving shell 506, it squeezes the pressing plate 508, causing the spring 510 to compress, which in turn drives the contact roller 509 on the through-frame 505 to press the cable, effectively preventing the cable from loosening and tangling. When the cable is pulled externally, the rotational characteristics of the contact roller 509 and the elastic extension function of the spring 510 form a buffer, leaving a safe pulling space and preventing the cable from directly detaching from the plug-in port.

[0035] When the contact roller 509 contacts the cable as it passes through the through slot 6, the limiting roller 701 initially limits its movement, reducing the friction on the cable during external pulling and preventing cable damage. At the same time, the cable is tightly fitted with the force roller 703 on the mounting bracket 702, forming a two-way elastic clamping structure between the contact roller 509 and the force roller 703, further enhancing the limiting effect. Under the continuous pushing of hydraulic oil by the contact plate 503, the hydraulic oil is transported through the delivery network 706 to the diversion pipe 707, and finally injected into the soft bladder 705 fixed by the mounting ring 704, achieving all-round clamping of the cable from top to bottom, significantly improving positioning stability. During later maintenance, it is only necessary to reverse the rotation rod 501 to reset the contact plate 503. The suction generated during the reset process can drive the hydraulic oil to flow back. The operator can directly adjust the cable without disassembling the clamping structure or bolts, making the operation convenient and efficient, avoiding the cumbersome drawbacks of traditional single clamping or bolt fixing methods.
