Description
Technical Field
[0001] The present invention relates to the technical field of adapters, and specifically to an ultra-short straight plug coaxial adapter. Background Technique
[0002] As an important member of the family of radio frequency coaxial connectors, a coaxial adapter is a core component for efficiently connecting signals between different transmission media or devices. Its design is based on the principle of coaxial transmission lines. Through a double-layer structure with an inner conductor for transmitting signals and an outer conductor for shielding interference, it ensures low loss and high anti-interference ability in high-frequency environments. With the continuous development of wireless communication technologies, coaxial adapters are increasingly widely used in the interconnection of wireless system modules, playing a crucial role in fields such as communication, communication networks, instrumentation, monitoring, medical, detection, civil aerospace, and national defense. In recent years, the market has put forward higher requirements for coaxial adapters, such as high frequency, high density, small size, light weight, fast and reliable connection, and strong vibration resistance.
[0003] Existing coaxial adapters have made leapfrog developments in terms of high frequency and miniaturization, but they cannot meet the use requirements of miniaturized modules with relatively small inter-board dimensions. As is well known, the smaller the volume of the adapter, the more difficult it is to assemble during production and to plug in during use. Therefore, it is urgent to solve the problems of small size, blind plugging, quick plugging, and self-locking. Therefore, an ultra-short straight plug coaxial adapter is proposed for the above problems. Summary of the Invention

The design of the pressing cylinder 82 can press and fix the insulating component 5 and the conduction component 6, and prevent the insulating component 5 from separating from the conduction component 6 during the curing process of the fixing glue layer 7. The design of the buffer and moisture absorption component 86 can provide buffering for the components in the housing 1. During the curing process of the fixing glue layer 7, the montmorillonite particles 862 in the sponge pad 861 can absorb the moisture volatilized from the fixing glue layer 7, enabling the fixing glue layer 7 to cure smoothly.
[0032] Workflow: When manufacturing the production device, first insert the conduction component 6 inside a set of insulation components 5, insert the inner conductor 61 inside the PTFE pressing ring 51 and the PTFE insulating cylinder 52, insert the slide bar 53 inside the chute 62, then insert the other end of the inner conductor 61 inside the retaining ring 9 in the housing 1, and insert another set of conduction components 6 inside the housing 1 and outside the inner conductor 61, so that the side of the PTFE pressing ring 51 close to the retaining ring 9 is in close contact with the retaining ring 9, thereby making the inner conductor 61 located at the center inside the housing 1. Next, pour the fixing glue layer 7 into the housing 1 from the glue injection hole 4, so that the fixing glue layer 7 fills the space between the two baffles and enters the accommodation groove 63 on the inner conductor 61. Then install the protection component 8, with the glue injection hole 4 facing upward, put the protective shell 81 on both ends of the housing 1, and squeeze the protective shell 81 so that the latch 85 on the right fixing block 83 is inserted into the card slot 84 on the left fixing block 83. At this time, the inside of the pressing cylinder 82 is in contact with the outside of the PTFE insulating cylinder 52, and the side of the pressing cylinder 82 close to the PTFE pressing ring 51 is in close contact with the PTFE pressing ring 51, and the installation of the protection component 8 can be completed. The design of the support plate 87 can support the housing 1 and the protective shell 81, keep the glue injection hole 4 facing upward all the time, and prevent the fixing glue layer 7 from flowing out. The design of the pressing cylinder 82 can press and fix the insulation component 5 and the conduction component 6, and prevent the insulation component 5 from detaching from the conduction component 6 during the curing process of the fixing glue layer 7. The design of the fixing ring 88 can increase the friction between the finger and the protective shell 81, making it more convenient for the operator to open and install the protective shell 81. The design of the buffer and moisture absorption component 86 can provide buffering for the components in the housing 1. During the curing process of the fixing glue layer 7, the montmorillonite particles 862 in the sponge pad 861 can absorb the moisture volatilized from the fixing glue layer 7, enabling the fixing glue layer 7 to cure smoothly, thereby fixing the insulation component 5 and the conduction component 6 in the housing 1 and realizing the basic signal transmission function of the device. The design of the insulation component 5, the conduction component 6 and their connecting components makes the assembly during the production process of the device more convenient, thus improving the production efficiency. When the device needs to be used, move the two housings 1 in opposite directions to make the latch 85 disengage from the card slot 84. At this time, insert the convex ring 2 on the left into the fixing tooling, and use the fixing tooling to insert the convex ring 2 on the right into the machine. During this process, the convex ring 2 on the right deforms towards the through slot 3. When it is completely inserted into the machine, the shape of the convex ring 2 on the right resumes. The outside of the convex ring 2 and the blocking and restoring ring 11 are in close contact with the inside of the machine, and the device is self-locked in the machine and cannot be pulled out. If forced to pull out, due to the close contact between the blocking and restoring ring 11 and the inside of the machine, the convex ring 2 on the right will break at the split groove 10 position, making the device unusable. When other equipment needs to be connected, other small modules can be connected to the outside of the convex ring 2 on the left. Due to the design of multiple through slots 3, the small modules can be quickly installed and disassembled. The design of the convex ring 2 and its connecting components enables the device to achieve quick disassembly and blind plugging, making the installation and disassembly more convenient, and enabling the device to have a self-locking function.
