Embodiment

Consult accompanying drawing 1, the present invention includes: by the plug 19 of A outer conductor 1, A insulator 2 and A inner wire 3 suits and by the socket 17 of B outer conductor 5, B insulator 7 and B inner wire 6 suits, A outer conductor 1 is that an end is provided with flange 14, the other end is provided with the sleeve pipe of bulge loop bayonet socket 11, socket cable joint 4 in its flange 14; A inner wire 3 is dressed up plug 19 for needle-like connector and A insulator 2 and A outer conductor 1 for the concentric circles cover; B outer conductor 5 is the sleeve pipe that an end is provided with horn mouth 12, middle part clamping spheroid 8, is provided with scrobicular ring bayonet socket 13 in the horn mouth 12, is sleeved on the spherical bearing 9 after

spheroid

8 and 5 clampings of B outer conductor; B inner wire 6 is dressed up socket 17 for pin hole shape connector and B insulator 7 and B outer conductor 5 for the concentric circles cover; When plug 19 was connected with socket 17, its A inner wire 3 was pegged graft with B outer conductor 5 with B inner wire 6 and A outer conductor 1, realizes the coaxial connection of radio frequency.

Consult accompanying drawing 2, the plug 19 that A outer conductor 1, A insulator 2 and A inner wire 3 are dressed up for the concentric circles cover, A outer conductor 1 are that an end is provided with flange 14, and the other end is provided with the sleeve pipe of bulge loop bayonet socket 11, socket cable joint 4 in its flange 14, A inner wire 3 is the needle-like connector.

Consult accompanying drawing 3 ~ accompanying drawing 4, plug 19 is formed for the concentric circles suit by A inner wire 3, A insulator 2, the cable joint 4 of needle-like connector and the A outer conductor 1 that is provided with flange 14, bulge loop bayonet socket 11 and six axial profile grooves 16.

Consult accompanying drawing 5, the socket 17 that B outer conductor 5, B inner wire 6 and B insulator 7 are dressed up for the concentric circles cover, B outer conductor 5 is the sleeve pipe that an end is provided with horn mouth 12, middle part clamping spheroid 8, be provided with scrobicular ring bayonet socket 13 in the horn mouth 12, spheroid 8 is provided with the straight hole 18 by the centre of sphere, by straight hole 18 spheroid 8 is connected on the B outer conductor 5, is sleeved on the spherical bearing 9 after
