Abstract
The invention belongs to a microwave communication device, relating to a radio frequency coaxial connector for a radio frequency antenna feed system. The radio frequency coaxial connector comprises an outer conductor (1), an insulation support (2), an inner conductor (4) and a compression threaded sleeve (6). The radio frequency coaxial connector is characterized in that the inner conductor (4) is fixed at the inner part of the outer conductor (1) through the insulation support (2); the compression threaded sleeve (6) is sleeved at the outer part of a cable and is fixed with the cable into a whole; the compression threaded sleeve (6) can be inserted into the outer conductor (1) to be fixed with the outer conductor in a revolving mode, and the inner conductor of the cable is contacted with the inner conductor (4) simultaneously. Because devices and processes of each cable manufacturer are different, the size structure of each cable is different, and the invention can not only be adapted for the cables of different manufactures simultaneously, but also be adapted for the cables of two different types of smooth copper pipes and corrugated coppers.
Description
Technical field
The present invention relates to a kind of radio frequency antenna-feedback system radio frequency (RF) coaxial connector.
Background technology
Coaxial cable can be divided into plain tube and bellows two big classes according to the structure of inner wire.Because equipment, technology, cost and the technical problem of different cable manufacturers, coaxial cable that each family produces (plain tube no matter, or bellows), the internal diameter of inner wire and the ripple size of outer conductor be difference to some extent all, and as the radio frequency (RF) coaxial connector of adaptive coaxial cable, can not specially join for each tame cable in the market, so need a kind of radio frequency (RF) coaxial connector that can adaptive most cables.
Coaxial cable connector is widely used in the antenna-feedback system, because the iron tower in the antenna-feedback system is all built the open air in, so install and all operations out of doors of debugging, convenient when therefore installing, need not becomes first-selection by the connector of other special-purpose complex installation instruments.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of outdoor study that is suitable for is provided, easy for installation, the radio frequency (RF) coaxial connector of energy adaptive most of producers cables (plain tube and bellows).
Technical scheme: a kind of radio frequency antenna-feedback system radio frequency (RF) coaxial connector of the present invention, comprise outer conductor, insulation support, inner wire and gland nut, described inner wire is supported and fixed on described outer conductor inside by described insulation, described gland nut is enclosed within the outside of cable, is fixed as one with cable; Described gland nut can insert in the described outer conductor, screws fixingly with it, and the inner wire of cable contacts with described inner wire simultaneously.
The inner surface of described gland nut end is provided with the arc groove that a circle falls in; First trough place of the corrugated surface of cable is with a spring coil; Described spring coil is embedded in the arc groove of described gland nut simultaneously, and cable and described gland nut are fixed as one.When screwing outer conductor and gland nut, spring coil can drop in the arc groove that gland nut falls in, and produces the outer conductor that reverse power removes to compress cable in the process of crimp.
The interface of described outer conductor is a double-decker, and its internal layer is sharp edge of a knife shape, can be inserted between cable surface and the spring coil; Described gland nut is inserted between the double-decker.
When cable was real core, the inner wire contact position of described inner wire afterbody and cable was the elastic contact pin structure, and the inner wire of cable is inserted in the described inner wire.Because the elastic contact pin structure has good elasticity, so the cable of different cable production firm, can both guarantee has enough elastic contact pressures when contact.
When cable was hollow, the inner wire contact position of described inner wire afterbody and cable was a umbrella elastic spring structure, and described inner wire is inserted in the inner wire of cable.Because umbrella-shaped structure has good elasticity, so no matter to be plain tube, still bellows, the cable of still different cable production firm, can both guarantee has enough elastic contact pressures when contacting.
Two sealing rings are assemblied in respectively on gland nut and the cable, thereby reach the effect of sealing by crimp, reach favorable waterproof property.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, radio frequency (RF) coaxial connector of the present invention is simple in structure, installs reliably, and electric property is good, and favorable waterproof property (IP68) is arranged;
2, the present invention 1-5/8 that different cable manufacturers are produced " cable, 1/2F cable, 7/8 cable and 1-1/4 " multiple coaxial cable such as cable has extremely strong suitability.
3, the present invention installs simple and reliablely, and the present invention need not technologies such as welding, crimping when mounted, directly screw screw thread just, and electric property is fine;
4, the present invention has only two assemblies, says mainly during assembling that two parts screw just, thus be not easy to mix up, easy for installation, be suitable for outdoor installation.
