Abstract
The utility model relates to an interphone miniaturization wideband antenna used by wireless communication equipment. The antenna comprises a shell, a screwed joint, an inner spring, an outer spring, a core rod and a filling injection molding body. The screwed joint is fixed on a left end portion of the shell. The inner spring is fixed on a right end portion of the screwed joint. The inner spring is located in the shell. The core rod is arranged in the inner spring. The outer spring is welded on a right end of the inner spring. The filling injection molding body used to fix the inner spring is arranged in the shell. The size of the antenna of the utility model is small, the length is short and frequency coverage is wide. According to the antenna of the utility model, a multi-coil multi-pitch mode is used, coupling among different coils is adjusted and a bandwidth of a needed frequency band is broadened so that a demand of a wideband interphone to the antenna is satisfied and the demands of different frequency band interphones and a non-wideband interphone are satisfied too.
Description
Technical field
The utility model relates to the antenna that a kind of Wireless Telecom Equipment uses, especially a kind of intercom miniaturization wide frequency antenna.
Background technology
Along with the development of domestic and international intercom technology, the volume of intercom product is more and more littler, and weight is more and more lighter.The product of the bulky of traditional heaviness more and more is not subjected to the welcome in market.The trend toward miniaturization of intercom product has also proposed the requirement of corresponding intercom antenna miniaturization to its antenna.
Along with the development of intercom technology, the frequency range that requires on the intercom is more and more, need have the antenna of wider frequency section to support.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of volume is little, length is short, frequency covers many intercom miniaturization wide frequency antennas.
According to the technical scheme that the utility model provides, described intercom miniaturization wide frequency antenna comprises shell, nipple, inner spring, outer spring, plug and filling injection molding body; Fixedly there is nipple left part at shell, fixedly there is inner spring right part at nipple, and inner spring is positioned at shell, is provided with plug in inner spring, right-hand member at inner spring is welded with outer spring, is provided with in the enclosure for the fixing filling injection molding body of inner spring.
Right-hand member at nipple is provided with the O RunddichtringO.
The utility model volume is little, length is short, frequency covers many intercom antennas, the utility model adopts the mode of the many pitch of multi-thread circle, and adjust the coupling between the different coils, the bandwidth of required frequency range is carried out broadening, thereby satisfy the wideband intercom to the demand of antenna, also can satisfy different frequency range, the demand of non-wideband intercom.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
This intercom miniaturization wide frequency antenna comprises shell 1, nipple 2, inner spring 3, outer spring 4, plug 5 and fills injection molding body 6; Fixedly there is nipple 2 left part at shell 1, fixedly there is inner spring 3 right part at nipple 2, and inner spring 3 is positioned at shell 1, is provided with plug 5 in inner spring 3, right-hand member at inner spring 3 is welded with outer spring 4, is provided with in shell 1 for the fixing filling injection molding body 6 of inner spring 3.
Right-hand member at nipple 2 is provided with O RunddichtringO 7.
Inner spring 3 is fixed on the M5 nipple 2 by soldering; form the most basic antenna structure; carry out the injection mo(u)lding first time then; form and fill injection molding body 6; this moment, inner spring 3 was thoroughly fixed; follow the appropriate area soldering outer spring 4 that exposes at inner spring 3; crimp when in inner spring 3, inserting teflon plug 5 protection springs not by shell 1 injection moulding; after finishing, assembling carries out the injection mo(u)lding of shell 1; outside moulding was finished by two steps; moulding first half of two molds; a moulding Lower Half; O RunddichtringO 7 is installed at last, and mainly acting as on the client intercom of O RunddichtringO 7 is well fastening, reduces M5 nipple 2 metal stridulations simultaneously and makes an uproar.
In the utility model, there is the tip side of inner spring 3 to add outer spring radiation uhf band to soldering place with outer spring 4, inner spring 3 produces the GPS frequency range with outer spring 4 solderings place to afterbody, owing to form coupled structure by the spring of two stacks, uhf band is wideer than common single spring intercom aerial radiation frequency band.
