Radio frequency (RF) coaxial connector is used for circuit board and circuit board, radio-frequency module and radio-frequency module and interconnected between circuit board and radio-frequency module.In current telecommunications field, as voice, data and image transmitting etc., the speed goes that required signal transmits is fast, stability and reliability more and more higher.But, under some equipment is often used in rugged environment, as traveling on mountainous region vehicle, bore equipment and high-altitude vehicle etc., while bearing sharp pounding, ensure the reliability and stability that high-frequency signal transmits again.

Due to, the radio frequency (RF) coaxial connector of prior art does not possess the function that any direction rotates adjustment, and when sharp pounding, plug and socket can cause mechanical failure under the effect of external power, cause connector to coordinate not in place, effectiveness reduces even complete failure.

Summary of the invention

The object of the invention is a kind of radio frequency (RF) coaxial connector designed for the deficiencies in the prior art, it adopts the socket of spinning ball structure, its plug can in socket 360 DEG C rotate freely, the position deviation produced due to vibrations is adjusted with this, guarantee that coaxial connector has good and stable radio-frequency performance and is connected reliably under vibration environment, be particularly useful for the high-frequency signal transmission under strong motion environment.

The object of the present invention is achieved like this: a kind of radio frequency (RF) coaxial connector, comprise the plug be set with by A outer conductor, A insulator and A inner wire and the socket be set with by B outer conductor, B insulator and B inner wire, be characterized in that A outer conductor is that one end is provided with flange, the other end is provided with the sleeve pipe of bulge loop bayonet socket, socket cable joint in its flange; A inner wire is needle-like connector and A insulator and A outer conductor is that concentric circles overlaps plug; B outer conductor is the sleeve pipe that one end is provided with horn mouth, middle part clamping spheroid, and spheroid is sleeved on spherical bearing; B inner wire is Pinhole-shaped connector and B insulator and B outer conductor is the socket that concentric circles is set with; Plug and socket grafting, its A inner wire realizes the coaxial of radio frequency with B inner wire, A outer conductor with the grafting of B outer conductor and is connected.

Scrobicular ring bayonet socket is provided with, the bulge loop bayonet socket clamping of scrobicular ring bayonet socket and A outer conductor in described horn mouth.

The sleeve pipe that described A outer conductor one end is provided with bulge loop bayonet socket is provided with several axial profile groove.

Described spheroid is provided with the straight hole by the centre of sphere, and spheroid is connected on B outer conductor by straight hole.

It is simple that the present invention compared with prior art has structure, coordinates reliable, guarantee that coaxial connector has good and stable radio-frequency performance and is connected reliably under vibration environment, is particularly useful for the high-frequency signal transmission under strong motion environment.

Embodiment

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

Accompanying drawings 3 ~ accompanying drawing 4, plug 19 is formed for concentric circles is set with by the A inner wire 3 of needle-like connector, A insulator 2, cable joint 4 and the A outer conductor 1 that is provided with flange 14, bulge loop bayonet socket 11 and six axial profile grooves 16.Accompanying drawings 5, the socket 17 that B outer conductor 5, B inner wire 6 and B insulator 7 are dressed up for concentric circles cover, B outer conductor 5 is provided with the sleeve pipe of horn mouth 12, middle part clamping spheroid 8 for one end, scrobicular ring bayonet socket 13 is provided with in 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 B outer conductor 5, is sleeved on spherical bearing 9 after spheroid 8 and B outer conductor 5 clamping.

Accompanying drawings 6 ~ accompanying drawing 7, socket 17 is formed for concentric circles is set with by the B inner wire 6 of Pinhole-shaped connector, B insulator 7, spheroid 8 and the B outer conductor 5 that is provided with horn mouth 12 and scrobicular ring bayonet socket 13, is sleeved on spherical bearing 9 after spheroid 8 and B outer conductor 5 clamping.
