Abstract

The invention discloses an airproof radio frequency coaxial connector, which comprises a connecting body 4; an inner cavity of the connecting body 4 is provided with an inner conductor 1; an insulator 3 is arranged between the inner conductor 1 and the connecting body 4; a chuck ring 5 is arranged between the insulator 3 and the connecting body 4; the outside of the connecting body 4 is provided with a remote radio unit RRU 12; the outside of the remote radio unit RRU 12 is provided with a flange 2 of which the outside is provided with a flat washer 7; and the outside of the flat washer 7 is provided with an elastic internal tooth washer 6 of which the outer end is provided with a nut 11. When harmful gas is about to invade a cavity of a filter through the flange 2, because sealing rings are arranged between the flange 2 and the connecting body and on the joint face between the flange 2 and the RRU, the harmful gas can be effectively prevented from invading the cavity of the filter; and when the harmful gas is about to invade the cavity of the filter between the inner conductor 1 and the insulator 3, the harmful gas is prevented by a clearance forced fit structure formed by agnail and the insulator 3; therefore, the airproof radio frequency coaxial connector has the characteristics of stable connecting performance and good air sealability.

Description

technical field [0001] The invention relates to a coaxial connector, in particular to an airtight radio frequency coaxial connector used for a filter. Background technique [0002] Since the airtight device of the existing structure is installed on the back of the RRU, that is, installed in front of the flange of the housing, it is easy to cause poor contact between the sealing device and the RRU due to installation errors, thereby causing the airtight device to fail. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide an airtight radio frequency coaxial connector, which can solve the axial and radial tolerances on installation, and has stable connection performance and good airtight performance features. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: an airtight radio frequency coaxial connector, including a ...
