Technical problem to be solved by this invention is to provide a kind of video/audio wire coaxial adatpter and manufacture method thereof, and its cost is low, and switching is convenient, simple to operate.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of video/audio wire coaxial adatpter, it is characterized in that, it comprises housing, first insulator, trim ring, inner wire, sealing ring, internal tooth packing ring, second insulator, nut, first insulator is positioned at housing, trim ring is between housing and the first insulator, inner wire is positioned at the inside of the first insulator, housing has an end of thread, sealing ring, internal tooth packing ring is enclosed within the end of thread successively, second insulator is connected with inner wire and is positioned at housing, nut is threaded with the end of thread.
Preferably, the diameter phi 0.5mm of described inner wire, the external diameter of housing is φ 1.91mm.
Preferably, described housing is being provided with a step surface near trim ring place, and housing is provided with a groove near step surface place.
Preferably, described housing adopts the brass material processing and manufacturing that electromagnetic conductivity is high.
Preferably, the material of described first insulator and the material of the second insulator are all polytetrafluoroethylene.
Preferably, what described inner wire adopted is maximum gauge is the tin bronze line of 3.04mm.
The present invention also provides a kind of manufacture method of video/audio wire coaxial adatpter, it is characterized in that, described manufacture method comprises the following steps:
Step one, first puts into housing by the second insulator and puts in place;
Rapid two, then the first insulator is installed to put in place from the fluting end of inner wire form same conductor assembly, the endoporus of the housing in the assembly then formed along step one by same conductor assembly, the needle tip of inner wire penetrates in insulator and puts in place;
Step 3, is placed between housing and the first insulator by trim ring;
Step 4, successively by sealing ring, internal tooth gasket sleeve on the end of thread of housing, then nut is threaded with the end of thread, till tightening.
Positive progressive effect of the present invention is: present invention eliminates traditional line and (generally will transfer transverse electromagnetic wave signal to audio & video signal, need to use the patchcord that a SMA turns transverse magnetic wave, add the adapter that a SMA turns audio frequency and video joint again, signal through switching often, add the loss of signal energy, the cost of switching is also higher), only need directly transverse electro-magnetic wave signal directly to be used video/audio wire coaxial adatpter of the present invention, be converted to audio frequency and video joint, only need this adapter just can realize, the cost needed is low, switching is convenient, simple to operate.
