Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
In the prior art, the connection type between connector and coaxial cable is generally divided into two kinds, i.e. elastic connection side
Formula and soldering connection type；
It as shown in Figs. 1-2, is the technical solution for using elastic connection way between connector and coaxial cable in the prior art,
In the technical solution, connector 1a includes hand-held part 1a-3 and the inner conductor 1a-1 positioned at its front end, in the inner conductor 1a-1
Axial middle part radially protruding be provided with elastic connection section 1a-2, realize and be connected with each other in connector 1a insertion coaxial cable 1b
When, the elastic connection section 1a-2 of radially protruding setting extends radially out the inner core for being stuck in the cable inner core 1b-2 of coaxial cable 1b
On the inner wall of hole 1b-1, to realize the good connection between connector 1a and coaxial cable 1b, due to using Elastic Contact, and bullet
Property linkage section 1a-2 outer diameter be greater than the inner wall size of inner chip hole 1b-1, thus by flexible deformation, realize connector 1a and same
Good connection between shaft cable 1b.

Case, in the technical scheme, connector 1c include hand-held part 1c-1 and the inner conductor 1c-2 positioned at its front end, are inserted in connector 1c
When entering to realize interconnection in coaxial cable 1d, pass through the periphery in inner conductor 1c-2 and the cable inner core 1d-2 of coaxial cable 1d
Inner chip hole 1d-1 between use tin silk filler, auxiliary with scaling powder, by welding, high-temperature heating so that connector in lead
Temperature between body and cable inner core reaches the fusing point (about 220-250 DEG C) of tin silk, so that the thawing of tin silk is filled in cable inner core
Between the two with the inner conductor of connector, tin solidifies after being heated, and using the solderability of tin and copper material, realizes between the two
Connection.
And this kind of connection type there are the shortcomings that are as follows: solid-state tin can melt welding two adjacent copper surface metals, make
With in process environment, long-term high-power, high current working condition easily leads to conductor temp.-elevating, must when the fusing point of thermal accumlation to tin
The tin layers that so will lead between cable inner core and connector inner conductor melt, so that connector and cable inner core is easy to cause to connect
Connect the serious consequence of failure.
Therefore in view of the foregoing drawbacks, the present invention provides following technical solutions to be deposited with solving connection type in current industry
