Radio frequency (RF) coaxial connector generally comprises three parts, housing, insulator and inner wire, the connection of adapter and cable, generally first inner wire welded with cable inner core or crimp, then put in housing, being positioned by the insulator of enclosure interior, finally carry out welding or crimping with cable outer conductor by housing, this traditional attaching mode has the disadvantages that

1, can protrude at the insulator of high-temperature condition enclosure interior in love, affect electrical property.

2, when installing cable, deformation known from experience by cable insulation.

3, cost is high, and wire stripping difficulty controls, and the easy rosin joint of inner wire affects electrical property.

And the radio frequency (RF) coaxial connector of prior art is half-and-half cut by insulator, then it is stuck in inner wire intermediate groove, forms the first molectron；Then the first molectron is pressed into the first outer conductor, forms the second molectron；Again the second molectron is pressed into the second outer conductor, form the 3rd molectron, again jump ring is enclosed within the 3rd molectron, jump ring is snapped in the groove of nut, the inner conductor structure of this radio frequency (RF) coaxial connector cannot be pressed directly into insulator, need half-and-half to cut insulator, again insulator is merged and be pressed into outer conductor in the conductor again, but owing to each accessory size is very little, processing cost is big, performance requirement is higher, fitted position is required very strict, this assembling mode can make the insulator end face out-of-flatness after merging press-in housing, thus affecting performance, scrappage is high, increase cost.

Therefore, it is necessary to a kind of new technical scheme is to solve the problems referred to above.

nullTechnical scheme: the utility model discloses a kind of radio frequency (RF) coaxial connector，Including outer conductor、Inner wire and insulator，Described inner wire is provided with groove and snaps in fixing for insulator，Described insulator includes the first insulator and the second insulator，Described first insulator structure is provided with the notch matched with inner wire groove structure in being，Outer is rectangular column structure，Described notch is semi-circular structure，The side, upper end of this first insulator is provided with the arc card end of thread of outward opening，The upper end opposite side of the first insulator is provided with vertical card end of thread，Described second insulator includes arcwall and is positioned at the link at arcwall two ends，Described link is equipped with and the block button hole of arc card end of thread or vertical card end of thread size fit，First insulator is by being fixed in the groove of inner wire with the second insulator buckle，The arcwall radian of described second insulator and the groove radian of inner wire match.

As further optimization of the present utility model, first insulator outer wall described in the utility model extends to vertical card end of thread from arc card end of thread along the first insulator and is provided with stopper slot, in this stopper slot, card is buckled with reinforcement, one end of described reinforcement is nested on arc card end of thread, and its other end is nested on vertical card end of thread.

As further optimization of the present utility model, Rib Thickness described in the utility model is more than stopper slot height.

As further optimization of the present utility model, outer conductor described in the utility model includes the first outer conductor and the second outer conductor, described first outer conductor and the second outer conductor are arranged on inner wire outer wall, and described reinforcement part is arranged between the first outer conductor and the second outer conductor.

Contact surface as further optimization of the present utility model, the first outer conductor described in the utility model and the second outer conductor Yu reinforcement is provided with the buckle slot for fixing reinforcement.

Beneficial effect: this utility model is compared with prior art, have the advantage that this utility model is by adopting the first insulator and the second insulator to be connected, avoid early stage to need to cut insulator, and adopt connector construction of the present utility model, its element size can control completely, it is substantially reduced part fitted position requirement, so that connector performance is more stable so that scrappage is relatively low.
