Concrete, described metal inside comprises metal inside body, metal inside body is the column structure of hollow, and metal inside body upper end is provided with flange, the metal inside body of flange lower end is equipped with multi-turn projection, metal inside body lower end is pyramidal structure, and the external diameter of pyramidal structure reduces from top to bottom gradually.
Flange is used for the spacing of nut; The external diameter of multi-turn projection is greater than the internal diameter of plastic core, for interference fit, metal inside is fixedly connected with plastic core, and pyramidal structure is convenient to metal inside and is fit into plastic core endoporus.
Concrete, described nut inside is provided with the boss coordinated with flange, and the internal diameter of boss is less than the external diameter of flange.
By coordinating, for the spacing location between nut and metal inside of boss and flange.
Further, described holding wire comprises CCS wire, coated PE insulating barrier, the first aluminium foil layer, woven shield, the second aluminium foil layer and PVC sheath, described PVC sheath and described metal inside interference fit successively outside described CCS wire.First aluminium foil layer and the second aluminium foil layer are double-sided aluminum foil layer.
Preferably, described metal inside is copper nickel plating inner core.
Preferably, described plastic core adopts POM plastic injection moulding integrated molding.
Preferably, described shell is copper nickel plating shell.
Further, also comprise dust cap, described dust cap covers on the upper end of described nut.Product, under not using state, can adopt dust cap to be covered by the open end of terminal, prevent dust from entering terminal, affect result of use.
The beneficial effects of the utility model are: a kind of high reliability audio frequency and video coaxial line that the utility model provides, all interference fit is adopted between terminal all parts and between terminal and holding wire, terminal is connected more firm with holding wire, improve the reliability of Total Product, also improve conforming product rate and production efficiency simultaneously; Adopt dust cap to be covered by the open end of terminal, prevent dust from entering terminal, affect result of use.
