Embodiment

As shown in Figure 1, many coaxial connectors are comprised of public type plug 1 and parent form plug 2, wherein, public type plug 1 has shell 7, parent form plug 2 has shell 11, and a plurality of interior coaxial connectors 3 are set on the shell 7 of public type plug 1, and a plurality of interior coaxial connectors 4 are set on the shell 11 of parent form plug 2.Interior coaxial connector 3 has independent shell 5, and interior coaxial connector 4 also has independent shell 6.

At the afterbody of shell 5, the gap location between shell 7 and shell 5 is equipped with spring 8, pressure ring 9 and opening inner shield ring 10.Spring 8 is enclosed within outside shell 5, the front end of spring 8 is pressed on the step of shell 5, and the rear end of spring 8 is pressed on the front end face of pressure ring 9, pressure ring 9 be enclosed within on shell 5 and with shell 7 tight fits, the rear end face of pressure ring 9 withstands on opening inner shield ring 10, and opening inner shield ring 10 is stuck on shell 7.The leading section of shell 5 has conical guide section 51.Between the axial remainder of shell 5 and shell 7, there is small gap.

The contact end face N(of the interior coaxial connector 4 of parent form plug 2 is datum level N) stretch out outside shell 11 front end faces, the length of its extension should meet length that the contact end face N causing due to cable assembling when interior coaxial connector 4 stretches out shell 11 front end faces not for the moment, and the contact end face M(that the shortest length L 1 of extension is greater than the interior coaxial connector 3 of public type plug 1 is datum level M) to the distance L 2 between the front contact end face of the shell 7 of public type plug 1.

The front end face cylindrical place of shell 6 has led a fillet 61, and the geomery of fillet 61 and guide section 51 matches, so that insert the front end guide section 51 of shell 5 of the interior coaxial connector 3 of public type plug 1.

Shell 7 front inner wall of public type plug 1 have a gathering sill vertical with front end face 12, there is a protruding key 13 perpendicular to rear end outer wall at the outer wall place, rear end of the shell 11 of parent form plug 2, this gathering sill 12 and protruding key 13 match, when connecting, by with public type plug 1 and parent form plug 2 between the preliminary guiding of the corresponding realization of profile, and guarantee corresponding one by one between public type plug 1 and a plurality of interior coaxial connector of parent form plug 2, the front end of the interior coaxial connector 4 of parent form plug 2 inserts the front end guide section 51 of the interior coaxial connector 3 of public type plug 1 subsequently, under the guiding of guide section 51, the interior coaxial connector of public type plug 1 and parent form plug 2 one by one correspondence swings location to guarantee axiality.
