Radio frequency connecting device adopting riveting and double-layer sealing mode

Abstract

The invention relates to a radio frequency connecting device adopting a riveting and double-layer sealing mode. The radio frequency connecting device is characterized in that the device comprises a first radio frequency connector (A) and a second radio frequency connector (B) which are connected together in a plugging manner, and also comprises a threaded sleeve (C) surrounding the first radio frequency connector (A) and the second radio frequency connector (B); the contact head adopts a fixing mode of pressing fit and then riveting, and is easy to process, so that the end head of the first shell shrinks, tightens and deforms towards the inside in the radial direction, the fixed end of the internal contact head is wrapped and tightened in the end head of the first shell, and the stable installation of the contact head is realized on the premise of not adding an external fixing piece; a mechanical axial positioning surface is arranged at the right end, and the first sealing ring and thesecond sealing ring are correspondingly arranged at the radial inner side and the radial outer side of the mechanical axial positioning surface respectively, so that sealing protection is realized onthe radial inner side and the radial outer side of the mechanical axial positioning surface at the same time, and the waterproof performance is further improved.

Description

technical field [0001] The invention relates to a radio frequency connection device, in particular to a radio frequency connection device using riveting and double-layer sealing. Background technique [0002] As a new type of low-intermodulation quick connector, the NEX10 connector has the advantages of stable and reliable connection and excellent transmission performance. At present, there have been mass-produced NEX10 connectors on the market, but due to the small overall size of the contact head, the design The precision requirement is high, so it is difficult to process, the processing cost is high, and the assembly is difficult when the contact head is pressed into the inside of the joint; [0003] At the same time, because the axial mechanical positioning surface of the first radio frequency connector and the second radio frequency connector in the prior art is close to the left end when plugged in, and only a single sealing ring is provided on the radial inner side of...

[0002] As a new type of low intermodulation quick connector, the NEX10 connector has the advantages of stable and reliable connection and excellent transmission performance. At present, there have been mass-produced NEX10 connectors on the market, but due to the small overall size of the contact head, the design The precision requirement is high, so it is difficult to process, the processing cost is high, and the assembly is difficult when the contact head is pressed into the inside of the joint;

[0003] At the same time, because the axial mechanical positioning surface of the first radio frequency connector and the second radio frequency connector in the prior art is close to the left end when plugged in, and only a single sealing ring is provided on the radial inner side of the right end, and then after the insertion is completed, due to After the axial mechanical positioning surface at the left end achieves axial positioning, there is a risk of moisture intruding from the right end and causing corrosion damage to the single sealing ring
