Specific embodiment
Embodiments of the invention will be described with reference to the drawings.Accompanying drawing is only to facilitate each embodiment of the explanation present invention, is not intended to carry out the explanation of exhaustive to the present invention, nor limiting the scope of the present invention.Present pre-ferred embodiments are given below in conjunction with the accompanying drawings, to describe technical scheme in detail.
As shown in Figure 1，Floating blind according to the present invention matches somebody with somebody RF coaxial adapters，Mainly include the first outer contact 11、Second outer contact 12、First central contact 21、Second central contact 22、Split washer 13、Reed 14 and cylindrical spring 16，First outer contact 11 and the second outer contact 12 lead to tubular structure in being，There is cylindrical hole 111 in first outer contact 11，Diameter of the outer diameter of the second outer contact 12 less than cylindrical hole 111，Second outer contact 12 can be inserted in cylindrical hole 111，Floating trough 112 is provided with cylindrical hole 111，The axial length of floating trough 112 is more than the floating distance of adapter and the thickness sum of split washer 13，The part of the insertion cylindrical hole 111 of the second outer contact 12 is provided with cannelure，Split washer 13 is located in cannelure，Diameter of the external diameter of split washer 13 more than cylindrical hole 111，Less than the diameter of floating trough 112，Diameter of the internal diameter of split washer 13 less than the second contact 12；The outer wall of the second outer contact 12 also has a ring projection, cylindrical spring 16 is located between cyclic lug and the bottom of the first outer contact 11, it is in impaction state during connection, pre-pressing force push power open on axial direction to providing between the first outer contact 11 and the second outer contact 12.
The bottom of cylindrical hole 111 is provided with the less shoulder hole 113 of a diameter, the interference fit of fluting end 141 of reed 14 is installed in shoulder hole 113, reed 14 is provided with annular projection 142, and circular protrusion 142 is stretched into inside the second outer contact 12, is contacted with the inwall of the second outer contact 12；First medium body 31 is located in the first outer contact 11, with the interior contact of the first outer contact 11, first medium body 31 is entered in the second outer contact 12 through the endoporus of reed 14, and second medium body 32 is located in the second outer contact 12, is contacted with the inwall of the second outer contact 12；First central contact 21 is located in first medium body 31, one end of first central contact 21 is provided with column contact pin 211, second central contact 22 is located in second medium body 23, one end of second medium body 32 is provided with tubular fluting jack 221, column contact pin 211 is entered in the second outer contact 12 through the inside of first medium body 31 during connection, and insert in tubular fluting jack 221, contact with the inwall of tubular fluting jack 221.
Second outer contact 12 is gap cooperation in radial direction with cylindrical hole 111, and gap value is：0.04mm-0.1mm.Larger cooperation depth and less gap value causes adapter when there is oblique cutting, and the first outer contact 11 and the second outer contact 12 are not in relative tilt, the alignment that not only can guarantee that whole adapter but also the stress deformation of fluting end 141 that can prevent reed 14.
The inside of second outer contact 12 is provided with shoulder hole, the inside for making the second outer contact 12 is divided into flotation chamber 121 and cylindrical cavity 122 by cascaded surface, flotation chamber 121 and the composition floating part 51 of column contact pin 211, column contact pin 211 runs through floating part 51, impedance compensation part 52 is provided with second outer contact 12, is made up of cylindrical cavity 122 and column contact pin 211.The inner face 123 of the second outer contact 12 and the floating distance 41 that the spacing on the top of annular boss 142 is adapter, the axial length of floating part 51 is more than the floating distance 41 of adapter.
The characteristic impedance of the floating part 51 is equal with the characteristic impedance of adapter.So, it is ensured that the impedance of floating part and the impedance of impedance compensation part are constant before and after floating.
Because there is the mutation of diameter dimension in the larger cylindrical cavity 122 of the middle part internal diameter of 121 and second outer contact of flotation chamber 12 of the second outer contact 12, thus be close to floating part 51 and be provided with impedance compensation part 52, it is made up of the column contact pin 211 of the afterbody of 122 and first central contact of cylindrical cavity 21 at the middle part of the second outer contact 12.As shown in figure 5, when adapter length changes：On the one hand the axial length 34 due to floating part 51 under adapter free state is more than the floating distance 41 of adapter, even if so that adapter is compressed into most in short-term, floating part 51 is yet suffered from, on the other hand due to before and after floating impedance compensation part 52 will not change so that adapter can keep constant voltage standing wave ratio before and after floating.
Although the foregoing describing the specific embodiment of the present invention, it will be appreciated by those of skill in the art that these are merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art can make various changes or modifications on the premise of the principle and essence without departing substantially from the present invention to these embodiments, but these changes and modification each fall within protection scope of the present invention.
