Abstract
The invention discloses a radio frequency coaxial cable connector, which comprises a shell, an insulator and a center needle, wherein the insulator is arranged in the shell; the center needle is pressed in the insulator; the shell is connected with a rear barrel; a cable clamp is arranged in the rear barrel; and the close-up mode of the cable clamp is in a thread screwing-in mode. When the rear barrel of the cable is clamped to be screwed into the shell, the center conductor of the cable constantly moves to the cutting slot of the center needle in the shell; the rear barrel is screwed in the shell; the clamping of the cable clamp is tightened; the internal diameter of the cable clamp is reduced; the outer conductor of the cable is clamped; meanwhile, the center conductor of the cable is inserted into the center needle; the outer conductor of the cable is clamped by the thread screwing-in mode closing up of the cable clamp; and damage on the cable by welding or crimping is avoided.
Description
Technical field
The present invention relates to telecommunications and instrumentation table technical field, more specifically relate to a kind of radio frequency coaxial-cable connector.
Background technology
The radio frequency (RF) coaxial connector that connects coaxial cable is not only simple and reliable for structure, be convenient to install, simultaneously reliability, shock resistance are good, machinery and electric property are good, also has water-proof function preferably simultaneously, long service life, and can guarantee that the distortion of coaxial cable signal transmission is minimum, improve the accuracy of signal transmission.
The radio frequency coaxial-cable connector of prior art, center needle and wire rod are to fetch fixedly wire rod inner wire and center needle by the tin wire bond, and the braiding of wire rod or outer conductor all are fixing by the crimping of other external member or welding, easily cause breaking of wire rod loosening.
Summary of the invention
The invention provides a kind of simple in structure, be convenient to assemble, cost is low, serviceability is good radio frequency coaxial-cable connector.
According to an aspect of the present invention, provide a kind of radio frequency coaxial-cable connector, comprise shell, insulator and center needle, be provided with insulator in the shell, center needle is pressed in the insulator, and shell is connected with rear thread sleeve, be provided with wire clamp in the rear thread sleeve, the closing in mode of wire clamp is the thread screw-in.The rear thread sleeve that clamps cable is fashionable to the shell inward turning, the center conductor of the cable constantly profile groove of the center needle in the shell moves, rear thread sleeve tightens in the enclosure, it is tight that the clamping of wire clamp becomes, the internal diameter of wire clamp reduces thereupon, the outer conductor of cable is clamped, and the center conductor of cable also inserts in the center needle simultaneously.The closing in of the thread screw-in by wire clamp clamps the outer conductor of cable, has avoided because the damage that welding or crimping cause cable.
In some embodiments, the center needle afterbody is provided with profile groove, and the afterbody of center needle is relative with rear thread sleeve.
In some embodiments, the other end of shell is connected with preceding swivel nut, and the front end of preceding swivel nut is provided with the silica gel circle.When two radio frequency coaxial-cable connectors connected use, the silica gel circle increased the sealing property between two radio frequency coaxial-cable connectors.
In some embodiments, rear thread sleeve is bolted in shell, is provided with first sealing ring in the rear thread sleeve, and shell and the rear thread sleeve place of being spirally connected are provided with second sealing ring.The effect of first sealing ring is the sealing that increases between radio frequency coaxial-cable connector and the cable.The effect of second sealing ring is the sealing that increases between rear thread sleeve and the shell.
In some embodiments, be provided with snap ring in the preceding swivel nut, snap ring is notched circular, and the silica gel circle is positioned at the outside of snap ring.Swivel nut can freely rotate on shell before snap ring made.
In some embodiments, the material of center needle is brass or phosphor-copper.Brass is softer, and the lathe car is easy to turning when processed, and the unit price of brass is lower, reduces cost; The good springiness of phosphor-copper, slow than brass when the lathe car is processed, the plug long service life.
In some embodiments, the material of insulator is polytetrafluoroethylene.Polytetrafluoroethylene is high temperature resistant, corrosion-resistant, difficult aging, good airproof performance.
In some embodiments, the material of shell is brass.The signal transmission performance of brass is better.
In some embodiments, the material of preceding swivel nut and rear thread sleeve is brass, and preceding swivel nut and rear thread sleeve are provided with coating outward, and coating is followed successively by red copper and ternary alloy three-partalloy from inside to outside.The signal transmission performance of brass is better, and the coating that is followed successively by red copper and ternary alloy three-partalloy also can increase the signal transmission performance of swivel nut.
