Three, utility model content

The purpose of the utility model just provides and a kind ofly connects 1/2 " radio frequency (RF) coaxial connector of coaxial cable; this radio frequency (RF) coaxial connector; not only simple and reliable for structure is convenient to easy for installationly, is easy to processing and assembling simultaneously; and guarantee that the distortion of coaxial cable signal transmission is minimum, improved the accuracy of signal transmission.

The technical scheme of the utility model is following: a kind ofly connect 1/2 " radio frequency (RF) coaxial connector of coaxial cable, it comprises swivel nut, contact pin, silica gel circle, snap ring, insulator, insulation support, lining, shell, sealing ring A, wire clamp, sealing ring B and rear thread sleeve etc.

Snap ring is snapped in the draw-in groove of shell, the silica gel snare connects through snap ring between swivel nut and the shell on shell, and swivel nut can freely be rotated, and can not pull.

Inside at the radio frequency (RF) coaxial connector shell is provided with insulator, and insulator places the first step place of enclosure, and insulator is with isolated non-conductive between shell and the contact pin; Inside at insulator is provided with contact pin, outside contact pin, is provided with insulation and supports, and insulation is supported isolated non-conductive between shell and the contact pin; Between shell and insulation support, be provided with lining, wire clamp arranged, in rear thread sleeve, be provided with sealing ring B at the lining peripheral hardware; Sealing ring B and cable closely cooperate, and can prevent rainwater, between rear thread sleeve and shell, are provided with sealing ring A; Sealing ring A can avoid rainwater to infiltrate; Through being threaded, tightening rear thread sleeve can clamp wire clamp between rear thread sleeve and the shell, thereby cable is firmly fixing.

The remarkable advantage of the utility model: a kind ofly connect 1/2 " not only simple and reliable for structure; that be convenient to install, reliability is high simultaneously, freedom from vibration is strong for the radio frequency (RF) coaxial connector of coaxial cable, this radio frequency (RF) coaxial connector, machinery and excellent electrical properties; and have very strong water-proof function; long service life, and can guarantee that the distortion of coaxial cable signal transmission is minimum, improve the accuracy of signal transmission.
