Description
Technical field
The utility model relates to the plant equipment of field of wireless communication, specifically, relates to a kind of built-in antenna of mobile phone support.
Background technology
In recent years, along with the development of wireless communication technique, mobile phone has become people's requisite communication tool of living.Along with the user to the improving constantly of communication need, cell-phone function increases day by day, has occurred such as new function such as bluetooth, GPS (Global Position System, global positioning system) communication, strange land communication, video telephone, Streaming Media.In addition, people have also proposed higher demand to the communication quality and the appearance and modeling of mobile phone, and antenna for mobile phone plays the important function of signal transmission between mobile phone and the base station as the main devices of received signal, so the quality of antenna performance is determining the quality of mobile phone conversation and data transmission quality.Along with the raising that people require the mobile phone appearance and modeling, antenna for mobile phone is also more and more to built-inization, miniaturization development, numerous ultra-thin, mobile phones with built-in aerial occurred.In addition, increase along with cell-phone function, require antenna for mobile phone to have the multiband function, CDMA (CodeDivision Multiple Access for example, CDMA mobile telecommunication) mobile phone is not only wanted can use in the North America but also want and can use at home, and need GPS positioning function etc., therefore corresponding mobile phone also needs integrated Cellular (honeycomb) 800MHz, PCS (Personal Communications Service, the person-to-person communication service) 1900MHz and three frequency ranges of GPS1575MHz, expansion along with frequency range, CDMA mobile phone from now on also may integrated AWS (Advanced Wireless Services, advanced wireless service) 1700MHz/2100MHz frequency range.To sum up, the restriction of the reducing of the increase of mobile phone frequency range, volume, appearance and modeling is all had higher requirement to antenna for mobile phone, and the antenna debugging difficulty also improves thereupon greatly.
Traditional mobile telephone external antenna is based on helical antenna and whiplike telescopic antenna, and these two kinds of antennas generally are positioned at the upper right corner or the upper left corner of mobile phone, are cylindric, and its metal radiant body is spirality or thin rod.This external antenna is simple in structure, and debugging is convenient, and has good directivity and radiance, and the antenna index generally can be done better.Therefore at the initial stage of mobile phone development, nearly all be the external antenna that adopts this simplicity of design and have superperformance.
But traditional external antenna has a bit of cylinder to expose to outer handset after all, has occupied bigger volume, and the antenna that exposes brought a lot of inconvenience to the user, damages easily and causes repair rate higher.In addition, external antenna has also brought the inharmonious of appearance and modeling, lacks the element that changes from aesthetic perspective.
In order to overcome the shortcoming of external antenna, built-in antenna of mobile phone just arises at the historic moment.The mobile phone of built-in aerial has advantages such as being easy to carry, using easily simply, be not fragile and handsome in appearance, is subjected to consumers in general's favor deeply.
Because built-in aerial is positioned at mobile phone inside, not for the user sees, so have very big flexibility, its shape is very strange, and is numerous.But in any case, present built-in aerial is main with PIFA (Planar Inverted-F Antenna, planar inverted-F antenna) antenna and unipole antenna still, and which kind of antenna form no matter all be unable to do without two parts and forms.A part is the main body of antenna, i.e. metal radiant body, and another part is exactly the supporter that the metal radiant body is relied on, i.e. antenna holder.The material of antenna holder is generally plastics, has played the effect of support and fixing metal radiant body.The fixed form of antenna generally is divided into two kinds, and a kind of is to be supporter with the mobile phone plastic casing directly, and the metal radiant body is fixed on the plastic casing; Another kind is that the metal radiant body is fixed in and has on definite shape and the plastic stent independently, and metal radiant body and plastic stent are done as a whole, carry out dismounting together.Because the design of built-in aerial support influence is produced and the convenience degree of maintenance dismounting, under the state of producing in enormous quantities now, simply the design of dismounting is most important.At present, the built-in antenna of cell phone support generally adopts the support trip to fix or the screw fixed form is fixed on interior PCB (the Printed Circuit Board of mobile phone, printed circuit board (PCB)) on the plate, but no matter which kind of fixed form of employing all is unfavorable for the installation and removal in production and maintenance process.
In addition, the structural design of built-in aerial support is also determining the area of antenna, is requiring antenna volume more and more littler and under the increasing situation of frequency range, it is particularly important that antenna area seems.At present, built-in aerial supporting structure commonly used as shown in Figure 1, comprise pcb board 101 and antenna holder 102, antenna holder 102 employing trips or screw and pcb board 101 or phone housing are fixed, available face for the antenna cabling generally has only two faces, be the level and the tapered outer surface of antenna holder 102, adopt this mode can not make full use of the cabling that solid space is used for antenna sheet metal radiant body.
The utility model content
The purpose of this utility model is in order to solve built-in mobile phone antenna holder inconvenient problem of installation and removal in production and maintenance process in the prior art.
In order to solve the problems of the technologies described above, the utility model proposes a kind of antenna for mobile phone support that is easy for installation and removal.The inboard of this antenna for mobile phone support is provided with a groove, the PCB of this groove internal fixation mobile phone; When needs dismounting antenna holder, only need take out the PCB in the mobile phone and get final product from groove.
Preferably, be provided with at least one spacing block piece in the groove of described groove, the PCB correspondence of mobile phone is provided with at least one draw-in groove, and when the PCB of mobile phone inserted, draw-in groove and spacing block piece were meshing.
Preferably, described spacing block piece is column or the spacing block piece of sheet.
Preferably, the inboard spill of described antenna holder hollow part is provided with at least one support ridge.
Preferably, the outer surface of described antenna holder is three structures of U-shaped, and at the outer surface support and the fixing metal radiant body of three structures of this U-shaped, this metal radiant body is as antenna for mobile phone.
The beneficial effects of the utility model are: the groove that utilizes antenna for mobile phone support inboard, the pcb board of clamping mobile phone, both made things convenient for the antenna for mobile phone support to be installed on the pcb board, and made things convenient for the antenna for mobile phone support to disassemble again, saved the time of producing assembling and maintenance from pcb board; Further, the outer surface of antenna for mobile phone support is designed to three structures of U-shaped, supports and the fixing metal radiant body, increased antenna cabling area, help improving the performance that transmits and receives of antenna at the outer surface of three structures of this U-shaped.
