Rapid connection and disconnection can be realized, the conventional threaded connection mode also can be implemented for precise test, and the radio frequency coaxial connector has high mechanical reliability and high electrical properties. The connection and disconnection radio frequency coaxial connector comprises a male connector and a female connector. A central inner conductor is arranged in the female connector, and a sunken hole is formed at the front end of the central inner conductor. An insulating medium is arranged on the central inner conductor. An outer conductor is arranged on the periphery of the insulating medium. A thread matched with the male connector is arranged outside the outer conductor. A central inner conductor is arranged in the male connector, wherein the front end of the central inner conductor has a tapered structure; an insulating medium is arranged on the central inner conductor; an outer conductor is arranged on the periphery of the insulating medium; and a connecting nut surrounds the outer conductor.

Description

A kind of radio frequency (RF) coaxial connector that connects separation

One, technical field:

The utility model relates to a kind of radio frequency (RF) coaxial connector, especially relates to a kind of radio frequency (RF) coaxial connector that connects separation.

Two, background technology:

In the background technology, the adapter of conventional threads connected mode, the connecting thread screwing length is longer, and the connect hours is long; The fast more traditional poor stability that is threaded of stable testing property of inserting connected mode.Can not satisfy the existing market requirement.A kind of traditional thread connecting mode shown in Fig. 1.Wherein Fig. 1 left side figure is the public type plug 11 of radio frequency (RF) coaxial connector, and right figure is a radio frequency (RF) coaxial connector parent form plug 12.The public type plug 11 of said radio frequency (RF) coaxial connector, it has the tapered structure of central inner conductor 111,111 front ends; Dielectric 112 is around central inner conductor 111; Outer conductor 113 is surrounded on dielectric 112, and nut 114 is surrounded on outer conductor 113, and sealing ring 115 is surrounded on outer conductor 113 front ends; Corresponding radio frequency (RF) coaxial connector parent form plug 12, it has central inner conductor 121,121 front ends and has shrinkage pool; Be used for being connected with public type plug central inner conductor 111; Dielectric 122 is around central inner conductor 121, and outer conductor 123 is surrounded on dielectric 122, and outer conductor 123 outsides have screw thread; Be used for being connected, and front end protrudes a segment distance with public type plug 11 nuts.During installation, public type plug 11 central inner conductor 111 are inserted parent form plugs 12 central inner conductor 121 shrinkage pools, tighten the nut 114 of public type plug with wrench, up to public type plug 11 outer conductors, 113 corresponding shrinkage pools and the applying of parent form plug 12 outer conductors 123 convex surfaces; During dismounting, back out the nut 114 of public type plug, extract public type plug with wrench.

Three, utility model content:

The utility model provides a kind of radio frequency (RF) coaxial connector that connects separation in order to solve the weak point in the above-mentioned background technology, and it can connect separation fast, can realize that also traditional thread connecting mode carries out comparatively accurate test.Have higher Mechanical Reliability and good electric property.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of radio frequency (RF) coaxial connector that connects separation, comprise public type plug and parent form plug, and be provided with central inner conductor in the described parent form plug; The front end of central inner conductor is provided with shrinkage pool; Central inner conductor is provided with dielectric, dielectric be peripherally installed with outer conductor, described outer conductor outer setting has the screw thread that matches with public type plug; Be provided with central inner conductor in the described public type plug, the front end of described central inner conductor is a pyramidal structure, and central inner conductor is provided with dielectric, dielectric be peripherally installed with outer conductor, be equipped with the attaching nut on the described outer conductor.

Compared with prior art; Advantage and the effect that the utlity model has are following: the utility model adapter improves on traditional basis, connector interface, and is simple in structure, dependable performance; The convenient use, the test request that can guarantee to hang down intermodulation simultaneously again, hangs down standing wave;

Four, description of drawings:

Fig. 1 is the structural representation of the radio frequency (RF) coaxial connector of existing screw-type connection;

Fig. 2 is the structural representation of the utility model.

Five, embodiment:

A kind of radio frequency (RF) coaxial connector that connects separation; Comprise public type plug 21 and parent form plug 22; It is characterized in that: be provided with central inner conductor 211 in the described parent form plug 22, the front end of central inner conductor 211 is provided with shrinkage pool, and central inner conductor 211 is provided with dielectric 212; Dielectric 212 be peripherally installed with outer conductor 213, described outer conductor 213 outer setting have the screw thread that matches with public type plug 22; Be provided with central inner conductor 221 in the described public type plug 22; The front end of described central inner conductor 221 is a pyramidal structure; Central inner conductor 221 is provided with dielectric 222, dielectric 222 be peripherally installed with outer conductor 223, be equipped with attaching nut 224 on the described outer conductor 223.
