Novel high temperature and high pressure-resistance water vapor seal N-K type terminal cable RF coaxial connector

Abstract

The invention relates to a novel high temperature and high pressure-resistance water vapor seal N-K type terminal cable RF coaxial connector comprising an outer conductor, an inner conductor, a dielectric body, a first sleeve, a second sleeve, a sealing sleeve and a screw sleeve, wherein the dielectric body and the first sleeve are both mounted in the outer conductor, the inner conductor is assembled with the dielectric body, one end of the second sleeve is sleeved on the first sleeve and has an interference fit with the outer conductor, the sealing sleeve abuts against the other end of the second sleeve, the screw sleeve and the outer conductor are threadedly locked, and the screw sleeve compresses the sealing sleeve. In the novel high temperature and high pressure-resistance water vaporseal N-K type terminal cable RF coaxial connector, the first U-type ring groove is provided with a first sealing ring, through which a waterproof function of the docking interface of the N-J-type connector is provided; a second sealing ring is disposed on the rectangular flange of the outer conductor, and the waterproof function between the connector and the mounting panel is provided by pressingthe second sealing ring to fit the mounting panel; and good sealing performance and highly reliable stability are provided under water vapor conditions of high temperature (200 DEG C) and high pressure (10 atmospheres).

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a novel high temperature resistant, high pressure water vapor sealed N-K type radio frequency coaxial connector for terminating cables.

At present, the conventional u...

AI Technical Summary

Problems solved by technology

At present, the conventional use environment of terminated cable coaxial connectors is either normal temperature and high pressure water vapor, or high temperature and normal pressure water vapor with a temperature upper limit of 125°C. There are few public cases of use that can meet the requirements of high temperature and high pressure water vapor at the same time.
