Description

TECHNICAL FIELD

[0001] The utility model relates to a quick connecting mechanism of TEM horn antenna, especially to a quick connecting mechanism of coaxial balun and TEM horn antenna, and belongs to the field of TEM antenna quick connecting mechanism. BACKGROUND

[0002] In the application of coaxial balun and TEM horn antenna, the connector is the key component to realize the electrical and mechanical connection between the two. Due to the particularity of coaxial balun and TEM horn antenna in structure, working principle and signal transmission demand, reasonable connector design is crucial. The role of the connector is not only to ensure the stable transmission of electrical signals, but also to meet the performance requirements of anti-interference, high frequency resistance, high power. In addition, the connector should provide mechanical support to ensure the fixation, stability of the antenna and balun, and prevent poor contact caused by external environmental changes.

[0003] However, the existing connection technology usually relies on welding, buckle connection and other ways, which has several deficiencies in practical application, affecting the overall performance of the connector. Although welding connection can provide better electrical connection, the welding point is very sensitive to external temperature changes, vibration and other factors. After a long time of use, the welding point may crack, de-solder or have poor contact, leading to antenna performance degradation or connection interruption, affecting the long-term stability of the equipment. And it is difficult to repair: once the welding connection fails, it is difficult to repair and replace, usually requiring re-welding, resulting in high maintenance cost. Secondly, the heat affected zone in the welding process may adversely affect the electrical characteristics of the connection point, especially in high frequency transmission, the thermal effect may cause signal distortion or loss. And the buckle connection may fail when bearing a large mechanical load, especially in high-power application scenarios, which may cause loose connection or poor electrical contact. Easy to age and fail: the plastic elements, springs and other components of the buckle connection are prone to failure due to temperature changes, aging and other factors, leading to a decrease in the long-term reliability of the connector. Electrical performance problems: the contact surface of the buckle connection is usually not as precise as welding or threaded connection, which may cause signal attenuation, reflection or distortion, affecting the performance of high frequency applications.

On the one hand, the support structure 7 is connected with the upper pressing plate 5 and the lower pressing plate 6 through the buckle structure to provide lateral support for the pressing plate assembly 4, thereby enhancing the stability of the pressing plate assembly 4 and enabling it to withstand a certain force without deformation or displacement when pressing the internal elements. On the other hand, the support structure 7 is in sliding connection with the insulating shell 1, so that the pressing plate assembly 4 can slide in a specific direction within the insulating shell 1, thereby facilitating the adjustment of the position of the pressing plate assembly 4 to adapt to internal elements of different sizes or layouts, and also facilitating the operation of the pressing plate assembly 4 and the internal elements during installation and maintenance. The support structure 7 is connected with the upper pressing plate 5 and the lower pressing plate 6 through the buckle structure, wherein the buckle structure can easily connect the support structure 7 with the pressing plate assembly 4, thereby facilitating quick and easy installation and easy disassembly for maintenance and replacement of parts. The two ends of the insulating shell 1 are provided with a fastener connection structure 8 connected with the upper pressing plate 5 and the lower pressing plate 6, so that the upper pressing plate 5 and the lower pressing plate 6 can accurately exert uniform pressure on the elements above and below the insulating layer 3, thereby optimizing the fixing and protection of the internal elements.

[0035] Further, as shown in Figures 1-8 , the insulating layer 3 is made of polytetrafluoroethylene material, which has excellent electrical insulation performance, can significantly enhance the insulation effect between the upper and lower areas inside the device, effectively prevent current leakage and electrical interference, improve the insulation strength of the device, prevent breakdown phenomenon, and ensure the safe and stable operation of the equipment in high-voltage and strong electric field environment.

[0036] , the insulating layer 3 is made of polytetrafluoroethylene material, which has excellent electrical insulation performance, can significantly enhance the insulation effect between the upper and lower areas inside the device, effectively prevent current leakage and electrical interference, improve the insulation strength of the device, prevent breakdown phenomenon, and ensure the safe and stable operation of the equipment in high-voltage and strong electric field environment.

In the case of heat generated during equipment operation, it can still maintain good physical and electrical properties, and will not deform or reduce insulation performance due to temperature rise, ensuring normal operation of the equipment under different temperature conditions. Figures 1-8As shown, the support structure 7 includes an upper pressure plate support structure 41 and a lower pressure plate support structure 42. The upper pressure plate support structure 41 is connected to the upper pressure plate 5, and the lower pressure plate support structure 42 is connected to the lower pressure plate 6. There are four upper pressure plate support structures 41 and four lower pressure plate support structures 42, located at both ends of the upper pressure plate 5 and the lower pressure plate 6, respectively. The upper pressure plate support structure 41 provides necessary support for the upper pressure plate 5, ensuring that the upper pressure plate 5 will not deform or shift excessively due to force when applying pressure to the components above the insulating layer 3, thereby ensuring effective fixation of the components and assisting the upper pressure plate 5 in accurately positioning within the insulating shell 1. The sliding connection with the insulating shell 1 allows the upper pressure plate 5 to be precisely adjusted to the appropriate position according to the layout requirements of the internal components and maintain this position during equipment operation. The pressure plate 5, which may be borne by internal components or external forces, is evenly distributed onto the insulating shell 1 to prevent excessive local pressure from damaging the insulating shell 1 or other components, thereby enhancing the structural stability of the entire device. The lower pressure plate 6 requires a stable support to reliably fix the components below it. The lower pressure plate support structure 42 undertakes this important responsibility, ensuring the stability of the components below during equipment operation. Different internal layouts of the equipment require the lower pressure plate 6 to be flexibly adjusted in position. The sliding connection and positioning function between the lower pressure plate support structure 42 and the insulating shell 1 meet this requirement, improving the adaptability of the device to different component layouts. Reasonable pressure transmission and equalization help protect the insulating shell 1 and other components, allowing them to maintain a good structural condition when subjected to pressure, thus maintaining the stability and reliability of the entire device.

[0037] Among them, such as Figures 1-8 As shown, the fastener connection structure 8 includes at least four sets of hexagonal screws 51 and hexagonal nuts 52. Multiple hexagonal screws 51 pass through one end of the upper pressure plate 5 and the lower pressure plate 6 respectively. The hexagonal screws 51 pass through one end of multiple upper pressure plates 5 or multiple lower pressure plates 6 and cooperate with the hexagonal nuts 52 to stably press the internal components. During the tightening process, axial tension is generated, which makes multiple upper pressure plates 5 or multiple lower pressure plates 6 fit tightly together, enhancing the stability of the connection and resisting the influence of external forces such as vibration and shaking. The hexagonal screws 51 can be tightened or loosened using common tools, which is convenient for installation and disassembly during equipment assembly, debugging and maintenance.

[0038] Furthermore, such as Figures 1-8As shown, the upper pressing plate 5 and the lower pressing plate 6 are fixed in a diagonal manner, in which the two ends of the upper pressing plate 5 and the lower pressing plate 6 extend diagonally to the outside of the insulating shell 1, a plurality of upper pressing plates 5 are arranged in a top-down consistent manner, and the upper pressing plates 5 extending to the same side of the insulating shell 1 are connected by the same hexagonal screw 51. The lower pressing plate 6 has a similar structure to the upper pressing plate 5, but the part of the lower pressing plate 6 extending to the outside of the insulating shell 1 is staggered with the corresponding part of the upper pressing plate 5 in the up-down position. The diagonal fixing manner enhances the pressing plate and effectively resists external forces in various directions, such as vibration, torsional force, shear force, etc., preventing the pressing plate from rotating and shifting within the insulating shell 1, ensuring that the pressing plate always maintains uniform and stable pressing force on the internal components. The extended parts of the upper and lower pressing plates 6 are staggered in the up-down position, further optimizing the stress distribution of the entire device. This design allows force to be more evenly distributed between components when the device is subjected to external forces, avoiding structural damage caused by local stress concentration and greatly improving the overall structural strength and stability of the device, prolonging the service life of the equipment. At the same time, a more reasonable connection layout is achieved in a limited space, making full use of the space outside the insulating shell 1, making the device structure design more compact and efficient, and effectively preventing breakdown.

[0039] As shown in the drawings, the insulating shell 1 is a rectangular box structure, and the upper and lower pressing plates 5 and 6 are arranged in the insulating shell 1 in a diagonal manner, in which the two ends of the upper and lower pressing plates 5 and 6 extend diagonally to the outside of the insulating shell 1, and the upper pressing plates 5 are arranged in a top-down consistent manner. The upper pressing plates 5 extending to the same side of the insulating shell 1 are connected by the same hexagonal screw 51. The lower pressing plate 6 has a similar structure to the upper pressing plate 5, but the part of the lower pressing plate 6 extending to the outside of the insulating shell 1 is staggered with the corresponding part of the upper pressing plate 5 in the up-down position. The diagonal fixing manner enhances the pressing plate and effectively resists external forces in various directions, such as vibration, torsional force, shear force, etc., preventing the pressing plate from rotating and shifting within the insulating shell 1, ensuring that the pressing plate always maintains uniform and stable pressing force on the internal components. The extended parts of the upper and lower pressing plates 6 are staggered in the up-down position, further optimizing the stress distribution of the entire device. This design allows force to be more evenly distributed between components when the device is subjected to external forces, avoiding structural damage caused by local stress concentration and greatly improving the overall structural strength and stability of the device, prolonging the service life of the equipment. At the same time, a more reasonable connection layout is achieved in a limited space, making full use of the space outside the insulating shell 1, making the device structure design more compact and efficient, and effectively preventing breakdown. Figures 1-8 As shown, the insulating shell 1 is provided with a pullable observation cover plate 71 at the top, and the observation cover plate 71 is connected to the insulating shell 1 through a sliding rail. The insulating shell 1 serves as the mounting base of the observation cover plate 71, and the sliding rail connects the observation cover plate 71 to the insulating shell 1, providing support and guidance for the pulling action of the observation cover plate 71. The observation cover plate 71 allows the operator to directly observe the working status of the internal components of the insulating shell 1 without opening or damaging the overall structure of the equipment, such as whether there are component failures, loose connections, abnormal heating, etc. This facilitates timely detection and processing of problems. In the closed state, it plays a certain auxiliary protective role in preventing dust and foreign matter from entering the insulating shell 1, while maintaining certain insulation performance and enhancing overall safety. The sliding rail is a prior art and will not be analyzed in detail.

[0040] As shown in the drawings, the insulating shell 1 and the cavity 2 are both rectangular, and the size of the insulating shell 1 in the three dimensions of length, width, and height is larger than that of the cavity 2. The insulating shell 1 is rectangular and larger in size than the cavity 2, providing full physical protection for the internal cavity 2 and the components that may be contained therein, preventing external objects from colliding, extruding, and rubbing against the internal components, ensuring that the equipment can operate safely in various environments, providing a clear boundary and positioning reference for internal components, facilitating equipment assembly and maintenance, and also benefiting the compactness and stability design of the overall structure. Figures 1-8 As shown in the drawings, the insulating shell 1 and the cavity 2 are both rectangular, and the size of the insulating shell 1 in the three dimensions of length, width, and height is larger than that of the cavity 2. The insulating shell 1 is rectangular and larger in size than the cavity 2, providing full physical protection for the internal cavity 2 and the components that may be contained therein, preventing external objects from colliding, extruding, and rubbing against the internal components, ensuring that the equipment can operate safely in various environments, providing a clear boundary and positioning reference for internal components, facilitating equipment assembly and maintenance, and also benefiting the compactness and stability design of the overall structure.

[0041] Figures 1-8 ​As shown, the pressure plate assembly 4 is snapped into the support structure 7 via elastic clips. The pressure plate assembly 4 and the insulating shell 1 are detachably connected via the support structure 7. The clips are elastic, providing a convenient detachable connection method. During installation, the pressure plate assembly 4 and the support structure 7 are snapped together with a simple operation. When disassembly is required for maintenance or replacement of parts, they can be easily separated. Due to its elasticity, it can adapt to slight positional deviations between the pressure plate assembly 4 and the support structure 7 to a certain extent, ensuring a tight and stable connection and improving the convenience of installation and maintenance. At the same time, the internal device can be structurally replaced for antennas of different sizes and coaxial baluns.

[0042] Among them, such as Figures 1-8 As shown, both the upper pressure plate 5 and the lower pressure plate 6 are made of 6061-T6 aluminum alloy with a hard anodized surface. Aluminum alloy has good thermal conductivity, which helps dissipate some of the heat generated by the components above and below the insulating layer 3 during operation, thus helping to maintain the components within a suitable operating temperature range. 6061-T6 aluminum alloy has high strength and hardness, which can meet the structural strength requirements of the upper pressure plate 5 and the lower pressure plate 6 for fixing the components, and is not prone to deformation, ensuring long-term stable pressure on the components. At the same time, this material has a relatively low density, which can reduce the weight of the entire device while ensuring strength.

[0043] like Figures 1-8 As shown, the principle of a quick connection mechanism for a coaxial balun and a TEM horn antenna provided in this embodiment is as follows: The two feed arms of the antenna are connected to the inner conductor transformation end and the outer conductor transformation end of the coaxial balun, respectively, to achieve effective transmission of electromagnetic energy. The upper pressure plate 5 is snapped into the upper pressure plate support structure 41 and the lower pressure plate 6 is snapped into the lower pressure plate support structure 42 by elastic buckles. The assembled pressure plate assembly 4 is slid along the insulating shell 1 so that the upper pressure plate 5 and the lower pressure plate 6 are in contact with the two feed arms of the antenna and the inner conductor transformation end and the outer conductor transformation end of the coaxial balun. The hexagonal screws 51 are inserted through the upper pressure plate 5 and the lower pressure plate 6 and extend to one end of the outer side of the insulating shell 1. By tightening the hexagonal nuts 52, the distance between the two upper pressure plates 5 and the two lower pressure plates 6 is shortened to the corresponding position. A slide rail is installed on the top of the insulating shell 1, and then the pull-out observation cover 71 is slidably connected to the insulating shell 1 through the slide rail to complete the installation of the observation cover 71.
