[embodiment]
With reference to figure 1 and Fig. 2, the utility model provide radio frequency (RF) coaxial connector to comprise to insert 1 with plug 2.Socket 1 comprises outer conductor 11, medium 12 and inner wire 13.Outer conductor 11 has inner chamber, supplies the counterpart of plug 2 to insert.Inner wire 13 adopts elastomeric materials, and inner wire 13 outer conductor 11 of packing into, 11 of inner wire 13 and outer conductors are fixed with medium 12.It is radially fixing that 12 in socket inner wire 13 and medium adopt inner wire 13 annular knurl modes to guarantee.Outer conductor 11 guarantees axial restraint with the medium 12 fixing hangnails that adopt, and has guaranteed the reliable mechanical performance.The installed surface of jack housing 11 is located at the face of being electrically connected, and the main body of socket can embed device interior (with reference to figure 4), has saved the space.
The inner wire 13 of socket 1, outer conductor 11 can be respectively form contact matching with inner wire 23, the outer conductor 21 of plug 2, and the medium 12,22 of socket 1 and plug 2 is respectively applied for realizes coaxial fixing between inner wire and outer conductor, has realized being electrically connected of system.
The inwall of socket outer conductor 11 is provided with an annular groove 14 as interlocking structure, and the front end outer wall of plug outer conductor 21 has ring boss 24 as corresponding interlocking structure.After plug 2 inserted socket 1, ring boss 24 was realized interlocking with annular groove 14, prevents that both from coming off mutually, need not use screw, has made things convenient for plug.In this instance, the width E=0.5-1.0 millimeter (mm) of annular groove 14, D outer diameter=8.5-9mm.The width E=0.4-0.8mm of ring boss 24, D outer diameter=8.3-8.6mm.Inner wire 13 outer diameter A=2.9-3.1mm, outer conductor 11 internal diameter C=6.6-7.1mm.
In this instance, the inwall of socket outer conductor 11 also is provided with the guiding straight hole, is used to guide the outer conductor 21 of plug 2 to insert.The width F=2-2.5mm of guiding straight hole.This scheme has realized fast insert-pull, the interlocking of socket 1 with plug 2, and it is stable more, reliable that system is connected, and the oblique cutting of stopping the quick plug connector existence causes socket inner wire jack to damage.
Electric of the socket of this instance height G=5.5-5.8mm, external diameter B=8-8.3mm, consistent with electric height of plug, internal diameter, realized joining mutually of plug and socket.N Connector 25 weak points of the universal high-power use of electric mating surface aspect ratio adopt embedded installation more than 1/3 simultaneously, solved the not enough problem of installing space, and power capacity are suitable with N Connector; Small size obviously reduces cost, economizes on resources.
In this instance, socket outer conductor 11 and plug outer conductor 21, electric the radially interface of locating is consistent with N type radio frequency (RF) coaxial connector 25; The fixed form that inner wire 13 supports is consistent with N type radio frequency (RF) coaxial connector, simultaneously, the part processing of small size, dimensional accuracy is higher, has guaranteed more superior electric property.
With reference to figure 3 and Fig. 4, in this instance, the outer conductor 11 of socket 1 and medium 12 support sections can be installed on equipment 3 inside, and promptly embedded installation has reduced the space, has expanded the range of application of this connector.In this instance, plug 2 can make setting height(from bottom) H be minimal at 1.5mm if adopt curved formula plug, makes inner wire, the outer conductor of plug and socket be electrically connected apart from shorter; Reduce the space, expanded the range of application of this connector.
Adopt said structure, the shell 1 of connector, medium 2, inner wire 3 radial dimensions coupling are standard 50 Ω, have satisfied the impedance requirement of communication system signal transmission, make signal more stable.
Adopt said structure, the material (being mainly copper material) that the part volume is little, use has still less reduced product cost, economizes on resources.
For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
