Description

A kind of video/audio wire coaxial adatpter

Technical field

The utility model relates to a kind of adapter, particularly relates to a kind of video/audio wire coaxial adatpter.。

Background technology

At present along with mobile communication, the develop rapidly of video display industry, its equipment of using also becomes the future development of diversification just can meet the need of market.Under the prerequisite of existing market, communication apparatus is more and more less to volume, multi-functional future development, and this radio frequency (RF) coaxial connector that just requires to match with it also must, to miniaturization, connect the future development of simplifying.

Existingly the signal of transverse electromagnetic mode to be transferred to audio-video signal and need to use two auxiliary adapters,, a SMA(Sub-Miniature-A, the meaning is a kind of small-sized mini joint) turn 1.13 patchcord, another is that to turn BNC(BNC be a kind of audio frequency and video joint to SMA) RF coaxial adapters, for being connected with conventional BNC audio frequency and video joint.Adapter used is more, could transfer by settling signal through twice switching, has and connects unsettled risk, and manufacturing cost is high, connects inconvenience, more time-consuming costly power.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of video/audio wire coaxial adatpter, and its cost is low, and switching is convenient, simple to operate.

The utility model 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, the first insulator, trim ring, inner wire, sealing ring, internal tooth packing ring, the second insulator, nut, the 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 on the end of thread successively, the 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.

Positive progressive effect of the present utility model is: the utility model has saved traditional line (generally will transfer transverse electromagnetic wave signal to audio & video signal, need to use a SMA and turn the patchcord of transverse magnetic wave, add again the adapter that a SMA turns audio frequency and video joint, signal through switching often, increase the loss of signal energy, the cost of switching is also higher), only need directly transverse electro-magnetic wave signal directly to be used to the utility model video/audio wire coaxial adatpter, be converted to audio frequency and video joint, only need this adapter just can realize, the cost needing is low, switching is convenient, simple to operate.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model video/audio wire coaxial adatpter.

Fig. 2 is the structural representation of the utility model middle shell and the first insulator.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As depicted in figs. 1 and 2, the utility model video/audio wire comprises housing 1, the first insulator 2, trim ring 3, inner wire 4, sealing ring 5, internal tooth packing ring 6, the second insulator 7, nut 8 with coaxial adatpter, the first insulator 2 is positioned at housing 1, trim ring 3 is between housing 1 and the first insulator 2, inner wire 4 is positioned at the inside of the first insulator 2, housing 1 has an end of thread 21, sealing ring 5, internal tooth packing ring 6 are enclosed within on the end of thread 21 successively, the second insulator 7 is connected with inner wire 4 and is positioned at housing 1, and nut 8 is threaded with the end of thread 21.Housing 1 is being provided with a step surface 11 near trim ring 3 places, and housing 1 is provided with a groove 12 near step surface 11 places.Step surface 11 is to be superminiature coaxial fitting with U.FL(U.FL with the effect of groove 12, is exclusively used in 1.13 lines) female joint is while connecting, plays the spacing effect of electric origin reference location and draw-in groove.

Video/audio wire comprises the following steps by the manufacture method of coaxial adatpter:

Step 1, first puts into housing 1 by the second insulator 7 and puts in place;

Step 2, then the first insulator 2 is installed to the same conductor assembly of formation that puts in place from the fluting end of inner wire 4, the endoporus 13 of the housing 1 in the assembly then same conductor assembly being formed along step 1, the needle tip of inner wire 4 penetrates in insulator 7 and puts in place;

Step 3, is placed on trim ring 3 between housing 1 and the first insulator 2;

Step 4, is enclosed within sealing ring 5, internal tooth packing ring 6 on the end of thread 21 of housing 1 successively, then nut 8 is threaded with the end of thread 21, and till tightening, this video/audio wire completes with coaxial adatpter.

The utility model video/audio wire has following characteristics with coaxial adatpter:

One, housing of the present utility model adopts the high brass material processing and manufacturing of electromagnetic conductivity, ensures effective transmission rate.

Two, the material of the material of the first insulator and the second insulator is all polytetrafluoroethylene.

What three, inner wire adopted is that maximum gauge is the tin bronze line of 3.04mm, and elastic strength is good, and contact is reliable.

Four, U.FL(U.FL is superminiature coaxial fitting, is exclusively used in 1.13 lines) joint employing machining, as Fig. 2, the positive and negative 0.02mm of the diameter phi 0.5mm(of inner wire), the diameter of the endoporus of housing 1 is φ 1.6mm, the external diameter of housing 1 is φ 1.91mm.
