Detailed Implementation
[0030] To make the objectives, advantages and features of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] To address the limitations of existing adapters in handling uncertain locations, varying board spacing, and high-frequency, miniaturized, and modular applications, this embodiment employs a floating structure that allows the adapter to be adapted to various needs while maintaining the stability and reliability of its RF performance.
[0032] Combination Figure 1 and Figure 2 As shown, this embodiment provides an axially floating radio frequency coaxial adapter, including a first adapter component and a second adapter component arranged sequentially along the axial direction.
[0033] The first transition assembly includes a first inner conductor 1, a first insulating medium 2, and a first outer conductor assembly 3 arranged sequentially from the inside to the outside, wherein the first insulating medium 2 fills the space between the first inner conductor 1 and the first outer conductor assembly 3.
[0034] The second transition assembly includes a second inner conductor 4, a second insulating medium 5, and a second outer conductor assembly 6 arranged sequentially from the inside to the outside, wherein the second insulating medium 5 fills the space between the second inner conductor 4 and the second outer conductor assembly 6.
[0035] The first inner conductor 1 and the second inner conductor 4 are coaxially arranged, with their ends close to each other passing through the first insulating medium 2 and the second insulating medium 5 respectively, and are axially connected. The first inner conductor 1 and the second inner conductor 4 can be selected from spring pins or wool buttons, etc.
[0036] The outer sides of the first outer conductor assembly 3 and the second outer conductor assembly 6 are slidably connected, and a spring 7 is installed between the inner shaft ends and is axially floatingly connected through the spring 7.
[0037] Specifically, the first outer conductor assembly 3 includes a first outer conductor 31, a first contact head 32, and a pressure ring 33 connected sequentially along the axial direction. A first convex ring 321 is provided at the center of the inner side of the first contact head 32. The outer side of the first insulating medium 2 is connected to the first outer conductor 31 and the first insulating medium 2, and the inner end is connected to the sidewall of one side of the first convex ring 321. One end of the pressure ring 33 is sleeved on the outer side of the first contact head 32, with an interference fit between them. A second convex ring 331 is provided on the inner side of the other end of the pressure ring 33, and a groove 34 is formed between the second convex ring 331 and the end face of the first contact head 32.
[0038] The second outer conductor assembly 6 includes a second contact head 61 and a second outer conductor 62 connected to each other, with the second contact head 61 positioned near the inner end of the first contact head 32. The outer side of the second insulating medium 5 is connected to the second contact head 61 and the second outer conductor 62, respectively. A third protruding ring 611 is provided on the outer side of the second contact head 61 near the end of the first contact head 32, and the third protruding ring 611 can move axially within the sliding groove 34, thereby achieving a sliding connection between the first outer conductor assembly 3 and the second outer conductor assembly 6.
[0039] One end of the spring 7 is installed at the center of the inner end of the second contact head 61. In its natural state, the other end of the spring 7 abuts against the other side wall of the first convex ring 321, and the third convex ring 611 abuts against the inner side wall of the second convex ring 331. Figure 4 (As shown); In the compressed state, the other end of the spring 7 is compressed by the first convex ring 321, resulting in axial displacement. At this time, the third convex ring 611 moves towards the first contact head 32 within the groove 34, thereby separating from the inner wall of the second convex ring 331. Figure 5 As shown in the figure, the axial floating connection inside the entire adapter is achieved because the first inner conductor 1 and the second inner conductor 4 are axially movable.
[0040] During this process, the pressure ring 33 can be used to ensure coaxiality, thereby ensuring better transmission of radio frequency signals by axial displacement.
[0041] like Figure 3 As shown, the reed 7 in this embodiment has a ring structure, which includes two interconnected semi-circular rings. One end of each semi-circular ring is symmetrically mounted on the inner end face of the second contact head 61, and the other end is a free end that is far apart from each other and inclined towards the end of the first contact head 32. In this embodiment, the central axes of the first inner conductor 1 and the second inner conductor 4 coincide with the central axis of the reed 7.
[0042] In this embodiment, multiple sockets are provided along the axial direction between the first insulating medium 2 and the first inner conductor 1 and the first outer conductor assembly 3, and between the second insulating medium 5 and the second inner conductor 4 and the second outer conductor assembly 6, for interlocking with external devices. The specific number of sockets can be designed according to actual needs.
[0043] To improve the stability of the connection between the components of the adapter, barbs 8 are provided at the connection between the first contact head 32 and the first insulating medium 2, and at the connection between the second contact head 61 and the second insulating medium 5, thereby ensuring the reliability of their axial connection.
[0044] This embodiment adjusts the existing integrated adapter into a split structure, thereby achieving axial floating connection and avoiding problems such as hard contact or installation gaps between modules, thus ensuring the stability and reliability of the adapter's operation.
[0045] This utility model is applicable to aviation, aerospace, ground, and shipborne fields. It has a simple overall structure, small size, and is suitable for various models such as SMP and SSMP.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
