Novel welding-type cable connector

The invention provides a novel welding-type cable connector, which comprises an insulator, an inner conductor and an outer conductor, wherein, the outer conductor is clamped and fixed on a threaded sleeve; the insulator is pressed in the outer conductor; the outer conductor is welded with the outer conductor of a coaxial cable; the inner conductor is welded with the inner conductor of the coaxial cable; a channel A is formed at the inner part of the insulator, and penetrates through the inner part of the insulator; the inner conductor is inserted in the channel A; a channel B is formed on the part connected with the cable at the tail part of the outer conductor; in the channel B, the outer conductor of the coaxial cable and the outer conductor of the connector can be welded, and a tin penetration-resisting lug boss is formed on the bottom plane surface of the channel B; an insulation layer is arranged on the outer side of the inner conductor of the coaxial cable; the tin penetration-resisting lug boss is embedded in the insulation layer on the coaxial cable; a round surface is formed by the tin penetration-resisting lug boss and the channel B; and tin rings are arranged between the round surface and the tin penetration-resisting lug boss respectively. The novel welding-type cable connector with simple structure effectively improves third order qualification rate, and has the advantages of stable consistent third order intermodulation and high qualification rate.
