Further, described parcel and the outer field coaxial cable shield net of metallic sheath with crimp pipe interference fit;
Further, the mouth of pipe external diameter R1< of described crimping pipe crimps the internal diameter R2 in tail chamber, crimping pipe with crimp tail cavity gap and coordinate;
Further, be provided with a sealing ring in described crimping tail chamber, inner side and the coaxial outer of a described sealing ring fit tightly, and the outside of a sealing ring fits tightly with the inwall crimping tail chamber;
Further, be provided with No. two sealing rings in described annular groove, inner side and the annular groove of described No. two sealing rings fit tightly, and the outside of No. two sealing rings and the inwall of adapter sleeve fit tightly.
The beneficial effects of the utility model are:
A kind of coaxial cable compression joint sealing structure that the utility model provides, its structure is simple, reasonable in design, the interference fit of metallic sheath and coaxial cable, greatly reduce the probability that cable gets loose, and after crimping, not only only cable shielding mesh is crimped, also coaxial cable is crimped on the inside simultaneously, the outer protection skin of coaxial cable is made to there occurs some metamorphosis, improve torsion and the axial force of coaxial cable pressure connection terminal, reduce the probability that coaxial cable gets loose, improve the shielding properties of the pressure connection terminal of coaxial cable simultaneously, reduce because of crimping operation, make the pressure connection terminal of coaxial cable impaired, thus the possibility causing the pressure connection terminal shielding properties of coaxial cable impaired, a sealing ring and No. two sealing rings are arranged for infiltration gap, greatly reduce the possibility that infiltration occurs at crimping position, improve water resistance, reduce the probability that electric fault occurs simultaneously, improve security performance.
