Preferably, described interior step extends to described transition part inner side from described contact site inner side.
In some embodiments, described swivel nut is fixed on described outer conductor transition part by jump ring, described transition part is arranged with outer recessed circle outward, and described swivel nut inwall rear is provided with indent circle, and described jump ring is contained in described outer recessed circle and described indent circle surrounds in the cavity forming.
Preferably, described dielectric comprises head that external diameter is less and extends and the larger afterbody of external diameter from described head back, and described head is contained in described interior step, and described afterbody is contained in described back cavity.
Preferably, in described back cavity sidewall, be provided with bulge loop.
In some embodiments, described inner wire comprises contact pin, extends back and external diameter is greater than the gripping section of contact pin and extends back and external diameter is greater than the back segment of gripping section from described gripping section from described contact pin, described gripping section is wrapped in described dielectric, described back segment is barred from described dielectric inner side, and described contact pin protrudes from described dielectric outside.
Preferably, there is certain taper on described contact pin top.
Compared with prior art, the beneficial effects of the utility model are:
1, in outer conductor, be provided with interior step, compensated the damaged thickness in the outer recessed circle place of contact site and transition part, thus intensity raising, not yielding, be applicable under the frequency of 26.5GHz.
2, dielectric afterbody is roomy, and in the time that dielectric is put into outer conductor, afterbody front is blocked by step, and rear snaps in bulge loop, therefore can prevent axial endplay.
3, inner wire back segment withstands dielectric, makes contact pin expose to the part fixed length of dielectric, and Male/female connector is coordinated better.
4, there is tapering on the less and top of contact pin Zhou Jing, easier capturing position when connector is connected.
