Description

Technical Field

[0001] The present invention relates to the technical field of communication antennas, and particularly to a connection structure between an antenna and a TR component. Background Art

[0002] In the field of the front-end adapter layer of phased array radars, an efficient connection between an antenna module and a TR component module is crucial. Currently, with the diversification of usage environments, especially when some products are applied to airborne platforms, new challenges are posed to the connection structure.

[0003] Traditional aperture transformation modules are mostly assembled by aluminum alloy plates through pins and screws. However, in actual application scenarios, due to the compact and narrow space, there is often not enough space for the design and installation of pins and screws, resulting in the inability to implement this traditional structure in many cases. Especially when one end requires a large-curvature surface, the problem is more prominent. For example, due to curvature limitations, the connector at the antenna end may have interference at the tail of the connector, making it impossible to arrange the connectors reasonably, seriously affecting the quick plug-and-play function between the antenna module and the TR component module, and further affecting the performance of the entire front-end adapter layer of the phased array radar. This also limits the application expansion of phased array radars in complex environments. Summary of the Invention

[0032] The purpose of the present invention is to provide a connection structure between an antenna and a TR component to solve the problems existing in the above - mentioned prior art and facilitate the connection between the antenna and the TR component.

[0033] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] As Figures 1 to 8 shown, this embodiment provides a connection structure between an antenna and a TR component, including:

[0035] A support body, on which a first connector (not shown in the figure) corresponding to the connector on the TR component is provided, and the connector on the TR component can be inserted and connected to the corresponding first connector;

[0036] Arc-shaped support plate 1, the arc-shaped support plate 1 is detachably connected to the support body, the antenna is installed on the arc-shaped support plate 1, the arc-shaped support plate 1 is provided with second connectors 6 corresponding one-to-one to the connectors on the antenna, the connectors on the antenna can be inserted and connected to the corresponding second connectors 6 in a pluggable manner, and the second connectors 6 correspond one-to-one to the first connectors, and the first connectors are signal-connected to the corresponding second connectors 6 through signal lines.

[0037] In this embodiment, the setting of the arc-shaped support plate 1 can adapt to the situation of large-curvature curved surfaces, enabling the connectors on the antenna to be reasonably inserted and connected to the second connectors 6 on the arc-shaped support plate 1, solving the problem of connector interference, ensuring the quick plugging and unplugging function between the antenna module and the TR component module, and thus improving the performance of the entire front-end transition layer of the phased array radar; through the combined design of the support body and the arc-shaped support plate 1, the space utilization is optimized, and it can adapt to the space-compact usage environment, solving the problem that the traditional structure cannot be realized in the scenario where the space is compact and one end needs to be a large-curvature curved surface.

[0038] In an alternative solution of this embodiment, preferably, the support body includes a mounting plate 4 and an enclosure assembly disposed between the mounting plate 4 and the arc-shaped support plate 1. The enclosure assembly includes two oppositely disposed first protection side plates 2 and two oppositely disposed second protection side plates 3. One end of each first protection side plate 2 is detachably connected to the mounting plate 4 and the other end is detachably connected to the arc-shaped support plate 1. One end of each second protection side plate 3 is detachably connected to one first protection side plate 2 and the other end is detachably connected to the other first protection side plate 2, and each first protection side plate 2 is located between the two second protection side plates 3.

[0039] In an alternative solution of this embodiment, preferably, as Figure 4 shown, weight-reducing grooves 7 are provided on the inner walls of each first protection side plate 2 and each second protection side plate 3, and reinforcing ribs 8 are provided on the inner wall of each first protection side plate 2; the provision of weight-reducing grooves 7 on the inner walls of each first protection side plate 2 and each second protection side plate 3 reduces the weight of the entire connection structure, which is beneficial to some application scenarios with weight requirements (such as airborne platforms); at the same time, the provision of reinforcing ribs 8 on the inner wall of the first protection side plate 2 enhances the strength of the first protection side plate 2 and improves the overall reliability of the connection structure.

[0040] In an alternative embodiment of the present embodiment, preferably, a first rib 11 with a dovetail-shaped cross-section is provided at one end of each first protective side plate 2 close to the arc-shaped support plate 1. A first dovetail groove 10 corresponding to the first rib 11 one by one is provided on the arc-shaped support plate 1. The first rib 11 can be slidably engaged with the corresponding first dovetail groove 10. The connection between the first protective side plate 2 and the arc-shaped support plate 1 in the form of a dovetail groove not only ensures the structural stability but also facilitates disassembly and installation when maintenance, repair, or component replacement is required, improving the maintainability of the product.

[0041] In an alternative embodiment of the present embodiment, preferably, a recess 13 is provided on the outer wall of one end of each first protective side plate 2 close to the arc-shaped support plate 1. An adapter plate 12 corresponding to the recess 13 one by one is provided on the arc-shaped support plate 1. The adapter plate 12 can be fitted and slidably engaged with the corresponding recess 13, and after installation, the adapter plate 12 is located outside the corresponding recess 13. During installation, the fitting and sliding engagement between the adapter plate 12 and the recess 13 can provide accurate positioning and guiding effects for the connection between the arc-shaped support plate 1 and the first protective side plate 2, ensuring that the two can be accurately docked during the installation process, facilitating quick and convenient assembly, and improving the assembly efficiency and accuracy. The provision of the adapter plate 12 and the recess 13 increases the contact area and connection points between the arc-shaped support plate 1 and the first protective side plate 2, making their connection tighter and more stable, capable of effectively withstanding various stresses generated when the antenna is connected to the TR component, reducing the possibility of connection loosening due to external forces such as vibration and impact, and improving the reliability and stability of the entire connection structure.

[0042] In an alternative embodiment of the present embodiment, preferably, the mounting plate 4 is connected to the first protective side plate 2 by screws, and the connection by screws is relatively convenient and stable.

[0043] In an alternative embodiment of the present embodiment, on the premise that the thickness of the mounting plate 4 permits, a second rib with a dovetail-shaped cross-section is provided at one end of each first protective side plate 2 close to the mounting plate 4. A second dovetail groove corresponding to the second rib one by one is provided on the mounting plate 4. The second rib can be slidably engaged with the corresponding second dovetail groove. The connection between the first protective side plate 2 and the mounting plate 4 in the form of a dovetail groove not only ensures the structural stability but also facilitates disassembly and installation when maintenance, repair, or component replacement is required, improving the maintainability of the product.

[0044] In an alternative embodiment of the present embodiment, preferably, all the second connectors 6 are located on the side of the arc-shaped support plate 1 close to the support body, and the insertion end of each second connector 6 penetrates through the arc-shaped support plate 1 and is exposed on the surface of the arc-shaped support plate 1 (such as Figure 2As shown in the figure; through holes 9 are provided on the mounting plate 4 corresponding to each first connector. All the second connectors 6 are located on the side of the mounting plate 4 close to the enclosure. The insertion end of the first connector is exposed at the opening of the corresponding through hole 9. This layout makes the arrangement of the connectors more reasonable, facilitating the insertion connection between the connectors on the antenna and the second connectors 6, and the insertion connection between the connectors on the TR component and the first connectors, improving the connection efficiency and stability.

[0045] In this embodiment, referring to Figures 1 to 3 and Figure 7 , all the second connectors 6 are distributed along the axial and circumferential directions of the arc-shaped support plate 1; since the arc-shaped support plate 1 is arc-shaped, the distribution of the second connectors 6 along its axial and circumferential directions can better fit the shape of the arc-shaped support plate 1, making full use of the surface space of the arc-shaped support plate 1, making the layout of the connectors more reasonable and compact, and effectively solving the problem of space limitation for installing connectors on the arc-shaped surface; the second connectors 6 distributed along the axial and circumferential directions are convenient for one-to-one correspondence and insertion connection with the connectors on the antenna. Whether it is during the installation process or the quick plugging and unplugging operation during actual use, the connection can be more conveniently and accurately achieved, reducing the installation difficulty and improving the connection reliability and efficiency.

[0046] In an alternative solution of this embodiment, preferably, as shown in Figure 1 and Figure 3 , sealing plates 5 are respectively provided at both ends of the arc-shaped support plate 1. The sealing plates 5 are detachably connected to the arc-shaped support plate 1; the sealing plates 5 can play a certain protective role for the components inside the connection structure (such as connectors, signal lines, etc.), preventing dust, impurities, etc. from entering the inside of the connection structure and affecting its normal operation, further improving the reliability and service life of the connection structure.

[0047] The specific usage method of the connection structure between the antenna and the TR component in this embodiment is as follows:

[0048] ① Assemble the mounting plate 4 with the enclosure assembly. Specifically, slide the second protrusion at one end of the first protective side plate 2 into the corresponding second dovetail groove on the mounting plate 4 to preliminarily position the first protective side plate 2 and the mounting plate 4, and then further fixedly connect them with screws; then, detachably connect the two second protective side plates 3 to the two first protective side plates 2 respectively to form the enclosure assembly, and at this time the support body assembly is completed.

[0049] ② Install the first connectors corresponding to the connectors on the TR component on the mounting plate 4, and signal-connect the first connectors with the corresponding second connectors 6 through signal lines to complete the wiring of the entire connection structure.

[0050] ③Install the arc-shaped support plate 1 through its connection structure with the first protective side plate 2; slide the first rib 11 at one end of the first protective side plate 2 close to the arc-shaped support plate 1 into the corresponding first dovetail groove 10 on the arc-shaped support plate 1. At the same time, make the connecting plate 12 on the arc-shaped support plate 1 fit and slide with the recessed part 13 on the outer wall of the first protective side plate 2, so as to realize the detachable connection between the arc-shaped support plate 1 and the support body, and ensure the stability and accuracy of the connection;

[0051] ④Install the antenna: Install the antenna on the arc-shaped support plate 1, and ensure that the connector on the antenna is inserted into the corresponding second connector 6 on the arc-shaped support plate 1 in an end-to-end connection;

[0052] ⑤Insert the connector on the TR component into the first connector on the support body in an end-to-end connection. At the same time, insert the connector on the antenna into the second connector 6 on the arc-shaped support plate 1 in an end-to-end connection, so as to realize the electrical connection between the antenna and the TR component and enable the signal to be stably transmitted between the two; The first connector, the second connector 6, the connector on the TR component, and the connector on the antenna all adopt quick-disconnect connectors to facilitate quick connection and disconnection, and improve the installation and disassembly efficiency;

[0053] ⑥When maintenance or component replacement of the connection structure is required, the TR component can be separated from the support body first, and then the arc-shaped support plate 1 can be separated from the support body by removing screws or other means, and then each component can be inspected, repaired or replaced; Since most of the connections between components adopt detachable connection methods, such as the sliding fit between the dovetail groove and the rib, screw connection, etc., the disassembly process is relatively convenient and facilitates maintenance operations.

[0054] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
