A kind of SMA phase place adjustable radio frequency joint
Technical field
The utility model relates to cable assembly technical field, particularly relates to a kind of SMA phase place adjustable radio frequency joint.
Background technology
In phased array radar, antenna array and all kinds of electronic warfare system, all require the cable assembly using phase matched precision high, in the production of routine, need by single-ended components reconditioning cable repair phase (namely produce assembly process in, the physical length of continuous adjustment cable repairs its electrical length, to ensure that error with the electrical length of batch assembly is in certain claimed range) ensure the phase matched of cable assembly.Cable assembly of the prior art needs constantly amendment adjustment union piece repairing in phase adjustment process, adjustment production hour is long, accessory loss is large, and once cable assembly repair mutually be shaped after, phase place adjusts more difficult again, based on the deficiencies in the prior art, await the cable assembly connector developing a kind of adjustable phase place.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides the SMA phase place adjustable radio frequency joint that a kind of phase place is easy to adjust, be applicable to extensive High-efficient Production.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of SMA phase place adjustable radio frequency joint, it comprises a housing, described housing is provided with the hexagonal boss of a locking, one end of described housing is provided with an outer annular groove, the first snap ring is provided with in described outer annular groove, outer sheathed one of described first snap ring connects swivel nut, the inside of described housing is provided with an insulator, a thimble is provided with in described insulator, the other end of described housing is provided with external screw thread, described external screw thread is provided with the adjusting nut of the first clamp nut and a control phase, an interior annular groove is provided with in the termination endoporus of described adjusting nut, the second snap ring is provided with in described interior annular groove, described second snap ring connects an outer conductor adjuster, one end of described outer conductor adjuster is stretched in described housing and is connected with housing conducting, in described thimble, conducting connects an inner wire adjuster, described inner wire adjuster extends in the inner chamber of described outer conductor adjuster, described outer conductor adjuster and inner wire adjuster are fixedly connected with coaxial cable again, the outer end of described outer conductor adjuster is provided with the locking screw of fixing outer conductor adjuster position, described locking screw is provided with the second clamp nut.
Be provided with the snap ring groove matched with the first snap ring in described connection swivel nut, in described connection swivel nut, be provided with internal thread.
The material of described inner wire adjuster and outer conductor adjuster is copper, and copper is gold-plated more outward.
During use, the one the second, two clamp nuts of outwarding winding, when adjusting nut turns clockwise, drive housing to move and inner space is diminished, cable joint electrical length shortens; Otherwise when being rotated counterclockwise by adjusting nut, drive housing to move and make inner space become large, cable joint electrical length is elongated, reaches phase-adjusted object, locks two clamp nuts after regulating again.
The beneficial effects of the utility model are: adopt said structure, by arranging the phase place adjustable radio frequency joint that can adjust the conductive lengths of connector, the state that inner and outer conductor design of Regulator in tunable radio frequency joint becomes to be similar to contact pin, jack contact plugs together, make the overall telescopic action of adjustable cable joint, active segment dielectric is air, regulate overall electrical length by the contact length changing inner and outer conductor adjuster, reach phase-adjusted object.The utility model phase place is easy to adjust, does not need to revise union piece in phase adjustment process, and part consistency is good, is applicable to extensive High-efficient Production.
