Description

Technical Field

[0001] The utility model relates to a wool button transfer layer module, belonging to the technical field of radio frequency connectors. Background Art

[0002] Radar has broad application prospects and important strategic significance in both military and civilian fields. With the continuous advancement of technology, its performance is constantly improving. As an indispensable component in radar systems, the technology of adapter boards is also constantly evolving and advancing. Radar adapter boards, through hardware and software design, implement radar signal acquisition, processing, and transmission. The RF connector adapter board primarily transmits the radar's high-bandwidth signals, achieving signal isolation and filtering to ensure the purity and reliability of the radar system signal. It can connect to a variety of devices, such as antennas, attenuators, and power meters, to meet the diverse interface requirements of radar systems.

[0003] Existing radar RF adapter boards primarily utilize vertical interconnection, aiming to achieve vertical transmission of RF signals between different layers while maintaining low signal loss, high integration, and stability. Mounting holes are provided at both ends of the adapter board as needed, allowing for placement of various RF adapters. These are connected via cables, which are buried between the boards, enabling the transmission and transfer of radar high-frequency signals.

[0004] The existing RF radar adapter layer has many limitations due to the characteristics of RF connectors, usage scenarios, and compatibility with other devices. First, the degree of standardization of the interface varies. RF connectors have a variety of interface types, such as SMA, SMB, TNC, and other models to meet the connection requirements of different devices and systems. However, due to the differences in interfaces between different manufacturers and standards in the market, connection compatibility issues with certain devices may arise. Due to the different connection methods and requirements of different radar systems, customized RF adapter boards may be required. This increases manufacturing costs and may require longer delivery times. For some special-purpose radar systems, such as systems with extremely high requirements for signal transmission quality, higher-performance RF connectors and more stable cables may be required, further increasing manufacturing costs.

[0005] Since the RF adapter board is interconnected between boards through RF connectors and cables, there are a large number of cables inside the RF adapter board, which easily causes congestion in the space between boards. The more channels there are, the more difficult the layout is. In addition, when the RF connector or cable is damaged, repair and replacement must be carried out in a crowded space, which is very inconvenient and does not meet the requirements for rapid repair and replacement of damaged equipment on the battlefield. It is a relatively inefficient modular design. Utility Model Content

[0034] The clamping plate 12 and the two cover plates are all electrical conductors and the three are connected to form a continuous outer conductor shielding member.

[0035] like Figure 1 As shown, in this embodiment, it is worth noting that there are two high-frequency dielectric bodies 6, which are symmetrically installed in the mounting hole in the middle of the clamping plate 12. The purpose of providing two is to facilitate the installation of the wool button and the protective cover 5 at both ends of the wool button 7. The assembly is as follows: first, the protective cover 5 is installed from the high-frequency dielectric body 6, and then one end of the wool button 7 is inserted into one high-frequency dielectric body 6, pressing against the protective cover 5, and the other end of the wool button 7 is inserted into the other high-frequency dielectric body 6, pressing against the other protective cover 5;

[0037] In this embodiment, the cover plate is divided into an upper cover plate 11 and a lower cover plate 13 , both of which have the same structure and the same internal components, which will not be described in detail in this embodiment.
