Description

Technical Field

[0001] This invention belongs to the field of mobile communication technology, and specifically relates to a connection structure and a communication device configured with the connection structure. Background Technology

[0002] In the field of mobile communications, base station antennas are key devices for signal transmission and reception, and their performance directly affects communication quality. Among these, the design of the internal air microstrip circuitry and coaxial cable connection structure of the base station antenna plays a crucial role in its overall performance.

[0003] In base station antennas, the common connection between the grounding metal plane of the air microstrip circuit and the coaxial cable is achieved through metallized vias. Specifically, the outer conductor of the coaxial cable is connected to the pads on the circuit board, and then the entire antenna feed network system is connected. This connection method meets the basic functional requirements of the antenna to a certain extent, but in practical applications and subsequent maintenance, many problems have gradually emerged.

[0004] On the one hand, the ground plane pads can only be parallel to the circuit board, resulting in a single connection method. This limited connection method restricts the flexibility and diversity of antenna circuit design, failing to meet the diverse performance and structural requirements of different application scenarios. For example, in some applications with special requirements for antenna size and shape, this single connection method may not achieve optimal design, thus affecting the overall performance of the antenna.

[0005] On the other hand, for antenna structures employing two stacked dual-polarized air microstrip circuit boards, subsequent maintenance is extremely inconvenient and carries significant risks. When antenna repair is required, the upper and lower circuit boards must be disassembled. During repeated soldering processes, the coaxial cable is susceptible to damage such as stretching and bending. The physical condition of the coaxial cable has a crucial impact on the antenna's intermodulation performance. Once the coaxial cable is stretched or bent, the antenna's intermodulation performance will decrease, thereby affecting the antenna's signal transmission quality and reducing the stability and reliability of the communication system.

[0006] Therefore, the existing air microstrip circuit and coaxial cable connection structure has many shortcomings in terms of structure and maintenance. There is an urgent need to propose an optimized connection structure scheme to solve the above problems and improve the performance and reliability of base station antennas. Summary of the Invention

[0007] The primary objective of this invention is to solve at least one of the aforementioned problems by providing a connection structure and a communication device.

[0008] To achieve the various objectives of this invention, the following technical solution is adopted: To meet one of the objectives of this invention, a connection structure is provided, comprising a dielectric plate and an elastic connector formed by bending a metal sheet. The dielectric plate has a power supply network on its front side and a grounding layer on its back side. The elastic connector has overlapping feet at both ends and a cable groove for supporting a coaxial cable in its middle. The opening of the cable groove faces the same direction as the front side. The dielectric plate has a mounting through hole. The elastic connector is inserted into the mounting through hole and elastically abuts against the hole wall of the mounting hole by its own elasticity. The two overlapping feet overlap the grounding layer to achieve grounding.

[0009] In one embodiment, the resilient connector includes a support section and a pair of support arms. The support section is bent to form the cable groove. The pair of support arms are located at both ends of the support section. The support arms are provided with overlapping feet at the ends of the support arms away from the support section. The overlapping feet are angled to the corresponding support sections.

[0010] In one embodiment, the support arm and the supporting section have an arc transition, so that the support arm and the supporting section form an arched structure.

[0011] In one embodiment, a pair of opposing abutment hole walls are formed in the mounting through hole, and the elastic connector applies opposing elastic forces to the pair of support arms so that the pair of support arms elastically abut against the pair of abutment hole walls respectively.

[0012] In one embodiment, the support arm is positioned substantially perpendicular to the front, and the vertical heights of the pair of support arms are not the same.

[0013] In one embodiment, a plurality of heat dissipation holes are formed on the bottom of the cable channel.

[0014] In one embodiment, an electroplated layer is formed on the cable tray, and the overlapping leg is welded and fixed to the grounding layer.

[0015] In one embodiment, the connection structure further includes a support plate, the reverse side of the dielectric plate is disposed on one side of the support plate, and an insulating sheet is provided between the reverse side and the support plate.

[0016] In one embodiment, the connection structure further includes a cable fixing component, which includes a main body and a plurality of cable clamps disposed on the main body, and each cable slot is provided with a corresponding cable clamp. One of the main body and the support plate has a plug-in slot, and the other has a plug-in block, and the plug-in slot and the plug-in block are plugged in and fixed.

[0017] In one embodiment, a receiving groove is formed on one end of the support plate, the main body is inserted into the receiving groove, the insertion groove or the insertion block is formed on the bottom of the receiving groove, the two groove walls of the receiving groove are respectively formed with slots, and the two sides of the main body are respectively formed with buckles, the buckles are fastened and fixed to the slots.

[0018] One objective of the present invention is to provide a communication device comprising a housing and a connection structure as described in any of the preceding objectives, the connection structure being disposed within the housing, a coaxial cable being introduced into the housing from outside the housing, a cable tray supporting the coaxial cable, the outer conductor of the coaxial cable being welded to the cable tray, and the inner conductor of the coaxial cable being electrically connected to the power supply network.

[0019] Compared with existing technologies, the present invention has many advantages, including but not limited to: The flexible connector of this invention replaces the traditional grounding metal plane pad structure of the circuit board, making the soldering method no longer limited to a single mode. Because the overlapping feet of the flexible connector are located on the reverse side of the dielectric substrate, and the opening of the cable channel faces the same direction as the front side of the dielectric substrate, the flexible connector forms a staggered structure, allowing soldering to be performed in multiple directions. It can be soldered not only horizontally but also vertically, greatly enriching the soldering methods. Soldering direction and method can be flexibly selected according to specific application scenarios and performance requirements, thereby achieving more optimized and diversified circuit designs.

[0020] The connection structure of this invention features mounting through holes on the medium plate. An elastic connector is inserted into these holes and, due to its elasticity, elastically abuts against the hole wall. This insertion and elastic abutment method makes the installation process simple and quick. Operators only need to accurately insert the elastic connector into the mounting through hole; no complex fixing or adjustment steps are required to complete the initial installation, significantly shortening installation time and improving efficiency. This is particularly suitable for large-scale production and rapid deployment scenarios.

[0021] The connection structure of this invention, based on the structure and installation method of elastic connectors, eliminates the need for complex disassembly and assembly operations during maintenance. When a fault occurs, maintenance personnel can quickly locate the problem and directly inspect or replace the elastic connectors or related components, without needing to disassemble the entire upper and lower circuit boards as in traditional structures. This avoids the risk of damage to the coaxial cable caused by repeated soldering, effectively protecting the physical state of the coaxial cable and ensuring stable antenna intermodulation performance. This convenient maintenance method significantly shortens maintenance time, reduces maintenance costs, improves the overall efficiency and lifespan of the equipment, and minimizes the impact of equipment failures on the communication system.

[0032] The connection structure provided by this invention uses an elastic connector to realize the electrical connection between the power supply network and the ground layer located on both sides of the circuit board. The outer conductor of the coaxial cable is directly soldered to the elastic connector. This invention replaces the metallized vias on the traditional circuit board with an elastic connector, meets diverse environmental requirements, and greatly improves adaptability in different application scenarios.

[0033] In a typical embodiment of the present invention, combined with Figure 1 and Figure 4 The connection structure 100 includes a medium plate 110 and an elastic connector 120.

[0034] Combination Figure 2 and Figure 5 The dielectric substrate 110 has two surfaces: a front surface 111 and a back surface 112. A power supply network 113 is disposed on the front surface 111, and a ground layer 114 is disposed on the back surface 112. Furthermore, mounting through holes 115 are provided on the dielectric substrate 110. In this embodiment, both the power supply network 113 and the ground layer 114 are fabricated on the dielectric substrate 110 using a printed circuit process, together forming a complete circuit board.

[0035] Combination Figure 3 and Figure 5 The elastic connector 120 is formed by bending a metal sheet. Specifically, both ends of the elastic connector 120 are bent to form overlapping legs 123, and a cable groove 124 is formed between the two overlapping legs 123. The opening direction of the cable groove 124 is consistent with the front side 111 of the dielectric substrate 110. Both overlapping legs 123 are connected to the grounding layer 114 disposed on the back side 112 of the dielectric substrate 110, so that the elastic connector 120 realizes the grounding function, which can effectively avoid signal interference and ensure the stability of signal transmission.

[0036] The main function of the cable tray 124 is to support the coaxial cable 200. In practical applications, the outer conductor of the coaxial cable 200 is soldered inside the cable tray 124. In this way, the outer conductor of the coaxial cable 200 is grounded through the elastic connector 120 and the grounding layer 114 in sequence, which can ensure the stable electrical performance of the coaxial cable 200 and reduce signal loss.

[0037] The surface of the cable tray 124 is coated with an electroplating layer. This electroplating layer improves the physical and chemical properties of the cable tray 124 surface, making it easier to solder the outer conductor of the coaxial cable 200 to it. Simultaneously, the electroplating layer enhances the connection strength between the coaxial cable 200 and the cable tray 124, improving connection stability and effectively preventing signal transmission problems caused by loose connections, further improving the reliability and performance of the entire connection structure 100.

[0038] Given that the elastic connector 120 is made of a bent metal sheet, it possesses excellent elastic properties. Combined with... Figure 4 and Figure 5 When the elastic connector 120 is inserted into the pre-drilled mounting through hole 115 on the medium plate 110, the elastic connector 120 will elastically abut against the wall of the mounting through hole 115 due to its own elasticity. The interaction force generated by this elastic abutment ensures that the elastic connector 120 is firmly inserted into the mounting through hole 115, effectively avoiding problems such as loosening and displacement caused by external factors, thereby ensuring the stability and reliability of the entire connection structure 100.

[0039] Since the elastic connector 120 is inserted into the mounting through hole 115, both ends of it are exposed outside the dielectric plate 110, greatly facilitating the user's coaxial cable 200 welding operation. During actual welding, the user can weld the coaxial cable 200 from different directions according to specific needs and the operating environment. For example, the outer conductor of the coaxial cable 200 can be welded from the front side 111 of the dielectric plate 110, or from the back side 112 of the dielectric plate 110. This multi-directional welding method breaks through the limitations of traditional welding methods, greatly improving the flexibility and convenience of welding operations, and helping to improve welding efficiency and quality.

[0040] The elastic connector 120 replaces the traditional solder pad structure of a grounded metal plane. The staggered structure of the elastic connector 120 allows for more diverse soldering methods. Soldering can be performed not only horizontally but also vertically, offering greater flexibility compared to traditional structures. Compared to traditional double-layer stacked air microstrip circuit boards, this invention is faster and more efficient during installation, significantly reducing installation time. Subsequent maintenance is also more convenient, eliminating the need for complex disassembly and assembly operations, allowing for quick location and problem-solving, effectively reducing maintenance and time costs, and improving the overall efficiency and lifespan of the equipment.

[0041] Specifically, combined Figure 3The elastic connector 120 includes a support section 121, a pair of support arms 122, and two overlapping feet 123. The support section 121 is bent to form a cable groove 124 for supporting the coaxial cable 200. The pair of support arms 122 are arranged opposite to each other and are respectively installed at both ends of the support section 121, together forming the elastic connector 120 with elastic properties. Each support arm 122 is correspondingly equipped with an overlapping foot 123. Specifically, one end of the support arm 122 is tightly connected to the support section 121, and the other end is securely connected to a corresponding overlapping foot 123.

[0042] Combination Figure 4 and Figure 5 The mounting through-hole 115 on the medium plate 110 is smaller than the overall size of the elastic connector 120 in its naturally extended state. When the elastic connector 120 is inserted into the mounting through-hole 115, it is compressed due to the space limitation of the mounting through-hole 115. During this process, the pair of support arms 122 move closer together, thereby reducing the overall size of the elastic connector 120. At this time, the pair of support arms 122 generate opposing elastic forces under the elastic force of the elastic connector 120 itself. This elastic force causes the pair of support arms 122 to elastically abut against a pair of opposing hole walls (referred to as abutment hole walls 1151 for ease of description) within the mounting through-hole 115. Through this elastic abutment action, the elastic connector 120 can be stably inserted into the medium plate 110, effectively maintaining the structural stability of the entire connection structure 100, ensuring reliable operation in various working environments, and avoiding problems such as signal transmission failures caused by loose connections.

[0043] In one embodiment, combined Figure 3 The support arm 122 and the supporting section 121 are connected by an arc-shaped transition, so that the support arm 122 and the supporting section 121 together form an arched structure. From the perspective of mechanical principles, the arched structure has excellent mechanical properties, can effectively disperse stress, and can significantly improve the elastic force between the support arm 122 and the supporting section 121.

[0044] This enhanced elasticity offers several advantages. Firstly, when the elastic connector 120 is inserted and fixed into the mounting through-hole 115 of the medium plate 110, the enhanced elasticity allows the connector 120 to enter the mounting through-hole 115 more smoothly. Furthermore, during insertion, the connector 120 can better adapt to the size and shape of the mounting through-hole 115, reducing resistance caused by size mismatch. Secondly, after the elastic connector 120 is inserted into the mounting through-hole 115, the enhanced elasticity allows for a tighter and more stable connection between the connector 120 and the mounting through-hole 115, effectively improving the structural stability of the entire connection structure 100. This ensures that the connection structure 100 maintains reliable performance under various complex working environments, reducing signal transmission interruptions and equipment failures caused by loose connections. In this embodiment, the invention is described using an n-shaped structure between the support arm 122 and the supporting section 121 as an example, but this should not be construed as a limitation of the invention.

[0045] In one embodiment, combined with Figure 3 The support arm 122 is approximately perpendicular to the front surface 111 of the medium plate 110. Furthermore, the vertical heights of these two support arms 122 differ, meaning they are not at the same height, resulting in an asymmetrical structure for the elastic connector 120. From a mechanical performance perspective, compared to a symmetrical structure, the asymmetrical structure can more effectively adjust and distribute stress, and under external force, it can produce more complex and reasonable deformation, thus significantly improving the overall elastic force of the elastic connector 120. This enhanced elastic force helps the elastic connector 120 better adapt to the size and shape of the mounting through-hole 115 when inserted into the medium plate 110, achieving a tighter and more stable connection, thereby improving the structural stability and reliability of the entire connection structure 100.

[0046] Furthermore, the different vertical heights of the pair of support arms 122 create a specific staggered effect in their spatial layout. This staggered design cleverly frees up the operating space required for welding, providing convenient conditions for welding the outer conductor of the coaxial cable 200 to the cable trough 124. During actual welding, operators can easily and accurately weld the outer conductor of the coaxial cable 200 to the designated position in the cable trough 124 without complex adjustments or operations, effectively reducing welding difficulty, significantly improving welding efficiency, and also reducing welding quality problems that may be caused by inconvenient operation, further ensuring the electrical performance and service life of the entire connection structure 100.

[0047] In one embodiment, combined Figure 3The cable tray 124 has multiple heat dissipation holes 125 at its bottom. When the outer conductor of the coaxial cable 200 is soldered to the cable tray 124, heat will concentrate at the soldering point. If the heat cannot be dissipated in time, it can easily lead to excessively high local temperatures, thus affecting the soldering quality. The multiple heat dissipation holes 125 can form a good heat conduction channel, allowing heat to be dissipated quickly and evenly. This uniform heat dissipation helps to ensure even heating during soldering, avoiding soldering defects such as cold solder joints caused by local overheating or undercooling, and significantly improving the stability of soldering. By improving soldering quality, the defect rate can be effectively reduced, material waste and increased production costs caused by poor soldering can be reduced, and the reliability and service life of the entire product can be improved, bringing higher value to users.

[0048] In a typical embodiment of the present invention, combined with Figure 3 The overlapping leg 123 and the corresponding support arm 122 are set at a certain angle. To clearly illustrate the technical solution of the present invention, this embodiment uses the example of the overlapping leg 123 and the support arm 122 being approximately perpendicular to each other for detailed explanation. However, it should be understood that this arrangement is merely illustrative and should not be construed as limiting the scope of protection of the present invention. In practical applications, the angle between the overlapping leg 123 and the support arm 122 can be adjusted and optimized according to different design requirements and usage scenarios.

[0049] Combination Figure 5 One end of the support arm 122 connected to the overlapping foot 123 extends through the mounting through hole 115 from the front side 111 of the dielectric substrate 110, causing the overlapping foot 123 to protrude relative to the back side 112 of the dielectric substrate 110. With the overlapping foot 123 protruding, it can achieve a stable connection with the grounding layer 114 on the back side 112 of the dielectric substrate 110, thereby achieving grounding and effectively introducing current into the grounding layer 114. This avoids electromagnetic interference and other problems caused by current accumulation, ensuring the normal operation of the entire electronic device.

[0050] Furthermore, the overlapping connection between the lap joint 123 and the grounding layer 114, in addition to achieving the grounding function, also provides further restraint for the elastic connector 120. During the insertion of the elastic connector 120 into the dielectric plate 110 and in subsequent use, this restraint effectively prevents the elastic connector 120 from loosening or shifting due to external forces or its own elasticity. This significantly improves the connection stability between the elastic connector 120 and the dielectric plate 110, ensuring that the entire connection structure 100 maintains reliable performance under various complex working environments and extending the service life of the equipment.

[0051] In this embodiment, the overlapping leg 123 and the grounding layer 114 are further fixedly connected by welding. The welding process firmly fixes the overlapping leg 123 to the grounding layer 114, which can effectively ensure the stability of the electrical and mechanical connection between the overlapping leg 123 and the grounding layer 114.

[0052] The welded connection between the overlapping leg 123 and the grounding layer 114 can resist the external force that the elastic connector 120 may be subjected to in the thickness direction, prevent the elastic connector 120 from being displaced or loosened in this direction, and thus ensure the positional stability of the elastic connector 120 in the thickness direction.

[0053] Simultaneously, the elastic connector 120 and the mounting through hole 115 form an elastic limit through elastic contact. When the elastic connector 120 is inserted into the mounting through hole 115, its elastic support arm 122 fits tightly against the hole wall of the mounting through hole 115 under its own elastic force, generating an elastic abutment force. This elastic abutment force allows the medium plate 110 to effectively limit the elastic connector 120 in the circumferential direction, preventing the elastic connector 120 from rotating or shifting in the circumferential direction.

[0054] Thus, the limiting effect in the thickness and circumferential directions provides comprehensive and stable positioning of the elastic connector 120 by the dielectric plate 110, ensuring reliable installation of the elastic connector 120 on the dielectric plate 110 and effectively preventing the risk of the elastic connector 120 detaching from the mounting through-hole 115 of the dielectric plate 110. In the connection application of the coaxial cable 200, this stable installation structure can maintain the electrical stability of the coaxial cable 200, ensure the accuracy and reliability of signal transmission, reduce signal attenuation and interference caused by loose connections, and improve the performance and service life of the entire connection structure 100.

[0055] In one embodiment, combined Figure 4 The dielectric substrate 110 is provided with multiple elastic connectors 120, which are distributed in a predetermined layout to meet practical application requirements. Each elastic connector 120 supports one coaxial cable 200. The elastic connectors 120 provide stable and reliable support and fixation for the coaxial cables 200. Through this one-to-one correspondence, multiple coaxial cables 200 are arranged in an orderly manner on the dielectric substrate 110 by means of multiple elastic connectors 120. The inner conductors of each coaxial cable 200 are electrically connected to the feed network 113 provided on the front side 111 of the dielectric substrate 110.

[0056] In a typical embodiment of the present invention, combined with Figure 1 and Figure 7 The connection structure 100 further includes a support plate 130 and an insulating sheet 140. The dielectric plate 110 is securely mounted on one side surface of the support plate 130, which provides reliable support for the dielectric plate 110, ensuring that the dielectric plate 110 maintains a stable posture under various working environments and preventing deformation or displacement of the dielectric plate 110 due to external factors, thereby affecting the performance of the entire connection structure 100.

[0057] The insulating sheet 140 is disposed between the support plate 130 and the dielectric plate 110, and is made of a material with excellent insulation properties. Through the isolation function of the insulating sheet 140, any electrical path that may exist between the support plate 130 and the dielectric plate 110 can be effectively blocked, preventing adverse effects on the electrical performance of the connection structure 100 due to electrical short circuits or other problems. This optimizes the overall electrical performance of the connection structure 100 and ensures the accuracy and stability of signal transmission.

[0058] In one embodiment, combined Figure 1 The support plate 130 has dielectric plates 110 on both its front and back surfaces, meaning that a circuit board is arranged on each side of the support plate 130. This fully utilizes the space resources of the support plate 130, achieving more circuit integration within a limited space. For communication devices equipped with the connection structure 100 of this invention, it can significantly reduce the overall size of the device, realize the miniaturization of the communication device, meet the development needs of modern communication devices for compactness and lightweight design, and also help reduce the manufacturing and transportation costs of the device, thereby improving the product's market competitiveness.

[0059] In a typical embodiment of the invention, the connection structure 100 further includes a cable fastener 150. Figure 1 and Figure 6 The cable fastener 150 includes a main body 151 and a plurality of cable clamps 152 disposed on the main body 151. The main body 151 serves as the basic support structure of the cable fastener 150 and has sufficient strength and stability to support the plurality of cable clamps 152. The plurality of cable clamps 152 are evenly or arranged in a predetermined layout on the main body 151 for clamping and fixing the coaxial cable 200.

[0060] The cable fixing member 150 is installed on one end of the support plate 130 along its longitudinal direction. The cable groove 124 on the elastic fixing member corresponds to one of the cable clamps 152 on the cable fixing member 150. Specifically, before the coaxial cable 200 is supported by the cable groove 124 of the elastic fixing member, it is first clamped by the corresponding cable clamp 152. The cooperative action of the cable clamp 152 and the cable groove 124 ensures that the coaxial cable 200 can be stably arranged on the support plate 130, effectively avoiding problems such as loosening or displacement of the coaxial cable 200 caused by external factors (such as vibration, impact, etc.).

[0061] Specifically, combined Figure 7 One end of the support plate 130 is a plug-in end 131, on which a plurality of plug-in blocks 132 are provided. Correspondingly, one end of the main body 151 of the cable fixing member 150 is a mating end 153, on which a plurality of plug-in slots 1531 are formed. In the actual assembly process, the plurality of plug-in blocks 132 on the plug-in end 131 are respectively inserted into the plurality of plug-in slots 1531 on the mating end 153, realizing the initial plugging and fixing of the cable fixing member 150 and the support plate 130, and ensuring the initial structural connection stability of the two.

[0062] In another embodiment, the positions of the plug-in block 132 and the plug-in slot 1531 are adjusted, that is, the plug-in slot 1531 is formed on the support plate 130, while the plug-in block 132 is formed on the main body 151 of the cable fixing member 150, which can also realize the plug-in cooperation between the two.

[0063] Furthermore, combined Figure 7 To enhance the connection stability between the cable fixing member 150 and the support plate 130, a receiving groove is formed on the insertion end 131 of the support plate 130, and the insertion block 132 on the support plate 130 is formed at the bottom of the receiving groove. Simultaneously, locking slots 135 are formed on the two opposite walls of the receiving groove. Correspondingly, latches 1532 are formed on both sides of the mating end 153 of the main body 151. During actual assembly, after the plug-in block 132 and the plug-in slot 1531 are initially plugged in, the two buckles 1532 of the main body 151 are respectively fastened and fixed to the two slots 135 of the support plate 130. Through this fastening cooperation between the buckles 1532 and the slots 135, the cable fixing component 150 is further firmly fixed to the support plate 130, effectively preventing the cable fixing component 150 from loosening or falling off due to external force during use, thereby ensuring the reliability and stability of the entire connection structure 100.

[0064] In one embodiment, a cable fastener 150 is disposed at each of the opposite ends of the support plate 130 along its longitudinal direction. These two cable fasteners 150 can orderly and stably introduce multiple coaxial cables 200 onto the dielectric substrate 110. The inner conductors of each introduced coaxial cable 200 are electrically connected to a feed network 113 disposed on the front side 111 of the dielectric substrate 110, thereby ensuring efficient and stable signal transmission between the coaxial cables 200 and the feed network 113, providing a solid foundation for the normal operation of the entire electronic system.

[0065] In one embodiment, combined Figure 1 and Figure 4 The connection structure 100 is capable of introducing at least two different types of coaxial cables 200. For ease of description, these two types of coaxial cables 200 are defined as a first coaxial cable 210 and a second coaxial cable 220, respectively. During introduction, the first coaxial cable 210 is simultaneously held by the cable clamp 152 on the cable fixing member 150 and supported by the cable groove 124 on the elastic connector 120. The second coaxial cable 220 is only held and fixed by the cable clamp 152 on the cable fixing member 150 during introduction and is not supported by the cable groove 124 on the elastic connector 120.
