Description
Technical field
This utility model relates to a kind of antenna, especially a kind of interphone antenna.
Background technology
The advantages such as in interphone antenna field, it is remote that whip antenna has speech range, and call is clear, for conventional U section
For, although whip antenna has the biggest advantage in performance, but its length is also many than common short and thick length of antenna.Whiplike
Antenna uses flexible shaft line or coaxial line structure, and short and thick antenna uses helical spring structure, so coming from structure
Saying, same frequency, whip antenna to be grown；Whip antenna is difficulty with double frequency or three frequency designs, and multiband design is typically passed through
The integrated other a antenna of short and thick inner antenna realizes multiband design.
Multifrequency antenna generally refers to dual-band antenna at present, and combination typically all V section adds GPS or U section and adds GPS, up-to-date
Intelligent transmitter receiver start integrating mobile communication function, usually GSM/CDMA and up-to-date LTE frequency range, LTE is up-to-date
4G communication standard.In order to realize double frequency, it is essentially all the most on the market and realizes, the most also with the spring of special shape
The structure that useful two kinds of spring assemblies use together.The spring of special shape refers to varying pitch, variable diameters, afterbody (head)
Turn round and penetrate centre or pass the types such as centre；Two kinds of spring assemblies are by two spring afterbody, head or the centre of different-diameter
It is connected.These structures can realize double frequency, advantage it is also obvious that cost is the highest, simple in construction, it is easy to manufacture in a large number, but lack
Point is also apparent from: the final performance of product depends entirely on degree of accuracy and the technology controlling and process of injection that spring manufactures, and finally
High frequency bandwidth is narrower, easily runs into the problem that concordance is poor during batch micro operations.
Pure spring antenna also have one compare distinct issues be antenna in actual use can not bending, because if folding
The curved shape just having influence on contained spring, easily causes spring section short circuit or deformation, thus affects performance, so on the market
Antenna is general to be all molded with hard material, if client in use hangs on one's waist, easily client's waist is hindered on top.
Existing multifrequency antenna design structure high frequency frequency range is narrow, poor performance, and spring makes the highest to required precision, supplier
Control difficulty relatively big, and require that the technique of injection mo(u)lding is the highest, need to be furnished with veteran assembling and Shooting Technique engineering
The whole production of Shi Jinhang controls.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the transmitter receiver sky of a kind of integrated 4G private network frequency range
Line, is a LTE1.4/1.8G double frequency that both ensured, and need not the product of the most complicated precision and technology controlling and process, this antenna set
Become the double private network frequency range of LTE, intercommunication function admirable, and belong to flexible antenna.The technical solution adopted in the utility model is:
The interphone antenna of a kind of integrated 4G private network frequency range, including a joint, the front port of joint connects as antenna
Mouthful, joint has and the jack of joint shell insulation；Also include spring, protection set, fixture, shell, flexible shaft line, metal
Paper tinsel；
Rear port at joint is inserted into a spring, and spring keeps insulation with the shell of joint；The front end of spring and joint
Interior jack back segment connects, the rear end connection fixture of spring；Protection set, protection set outer layer it is provided with outside spring and fixture
Metal paper tinsel；
Fixture is connected with the flexible shaft line front end at fixture rear；Shell is wrapped in the metal forming outside joint, protection set, with
And on flexible shaft line.
Further, the joint of this interphone antenna uses sub-miniature A connector；In sub-miniature A connector includes SMA shell and SMA shell
SMA jack, and the front insulator between SMA jack and SMA shell, in SMA shell back segment and the rear insulator of rear port；
SMA jack leading portion is used for connecting the aerial lug contact pin of insertion, SMA jack back segment and the spring inserting SAM joint rear port
Front end riveting is together；Spring leading portion passes rear insulator.
Further, the rear end of spring is welded with fixture.
Further, fixture is connected with the flexible shaft line riveting at fixture rear.
Further, shell is the soft shell of injection mo(u)lding.
Further, this utility model also includes the label ring being glued to antenna head.
The utility model has the advantage of:
1) LTE private network 1447-1467MHz/1785-1805MHz two-band it is integrated with.
2) simple in construction, and performance can be adjusted in the later stage, easily produces.
3) flexible antenna, will not damage terminal client.
Accompanying drawing explanation
Fig. 1 is that structure of the present utility model forms schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
The interphone antenna of the integrated 4G private network frequency range that the utility model proposes, as it is shown in figure 1, include a sub-miniature A connector,
Also include spring 5, protection set 6, fixture 7, shell 8, flexible shaft line 9, metal forming 10, label ring 11；
The front port of sub-miniature A connector is as antenna connector, and sub-miniature A connector includes that the SMA in SMA shell 2 and SMA shell 2 inserts
Front insulator 3 between hole 1, and SMA jack 1 and SMA shell 2, the interior rear insulator 4 with rear port of SMA shell 2 back segment；SMA
Jack 1 is made by sheet metal, after leading portion can connect the aerial lug contact pin of insertion, SMA jack 1 back segment and insertion SAM joint
The spring 5 front end riveting of port is together；Spring 5 leading portion passes rear insulator 4, due to the effect of rear insulator 3, spring 5 with
SMA shell 2 keeps insulation；
The rear end of spring 5 is welded with fixture 7；
