The technical scheme disclosed by the invention has a simple structure, is convenient to assemble, saves metal elastic sheet parts and related processes in the prior art, greatly lowers the cost and improves the production efficiency.
Description
Technical field
The present invention relates to a kind of mobile terminal antenna, particularly relate to a kind of FPC antenna structure.
Background technology
Along with the raising of people's living standard and the development of mechanics of communication, mobile phone is more and more universal in people's life, becomes also more and more important in people's life simultaneously.Along with the enhancing of the universal and cell-phone function of mobile phone, mobile phone has developed into a kind of Portable electronic equipment of Multifunctional multimedia from a kind of simple communication tool.Thereby for consumers in general's daily life and use provides many convenience.
At present, mobile phone volume is more and more less, and moulding is more and more changeable, for guarantee antenna performance and with the coordinating of hand set machine shell, FPC (Flexible Print Circuit) antenna has obtained increasing use.At present, FPC formula antenna is all to contact with PCB circuit board by independent metal clips, and so, metal clips itself and assembly cost are all no small costs.Those skilled in the art is devoted to the FPC antenna structure that development cost is low.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome in prior art, and FPC antenna and pcb board contact site complex structure are assembled loaded down with trivial detailsly, and the deficiency that cost is high, provides a kind of novel FPC antenna.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of FPC antenna, comprise antenna holder and antenna body, its feature is, described antenna body is fixedly installed on antenna holder, described antenna holder comprises a main part and a kink, described kink, under the elastically-deformable state of generation, is pressed in described antenna body on one PCB circuit board.
Preferably, described kink comprises turn section, breeze way and parallel-segment, described turn section is connected with described main part and forms the knuckle that is greater than 180 degree, and described breeze way is slightly long and be connected described parallel-segment and breeze way connection parallel with described main part with turn section.
Preferably, described antenna body sticks on described antenna holder.
Preferably, described PCB circuit board scribbles tin cream piece in the contact position with antenna body.
Preferably, described antenna holder is plastic material.
Preferably, described breeze way arranges positioning protrusion portion, and described antenna body arranges location hole in corresponding position.
Preferably, described antenna body arranges a segmental arc at position corresponding to described breeze way, and described segmental arc does not contact with breeze way.
Positive progressive effect of the present invention is: this FPC antenna structure is simple, easy to assembly, has saved part and the operation of metal clips in prior art, greatly reduces cost, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the FPC antenna assumption diagram according to a specific embodiment of the present invention.
Fig. 2 is the FPC antenna assumption diagram according to another specific embodiment of the present invention.
Embodiment
Embodiments of the invention describe with reference to the accompanying drawings.In Figure of description, the element with similar structures or function will represent with identical component symbol.Accompanying drawing is each embodiment of the present invention for convenience of explanation just, is not to carry out to the present invention the explanation of exhaustive, neither limit scope of the present invention.
Fig. 1 shows the FPC antenna structure of the present invention's one specific embodiment.In this embodiment, it is upper that plastic rubber bracket 10 is arranged on mobile phone inner casing housing (scheming not shown), integrally formed with mobile phone inner casing housing.Plastic rubber bracket 10 is close to FPC antenna body 20, plastic rubber bracket 10 comprises main part 11 and kink 12, in a preferred embodiment, kink comprises turn section 122, breeze way 124 and parallel-segment 126, turn section 122 is comprised of two straight sections, avoids the stress that causes because turning angle is excessive the adverse effect such as to concentrate.Turn section 122 is connected with main part 11 and forms certain knuckle, and breeze way 124 is connected with turn section 122, and parallel-segment 126 is connected with breeze way 122 and roughly forms the knuckle of 180 ° with main part 11.Main part 11 and the kink 12 of plastic rubber bracket 10 are integrally formed.Like this, kink 12 can inwardly carry out elasticity bending.Those skilled in the art will appreciate that turn section 122, breeze way 124 and parallel-segment 126 also can make with other version, as long as can finally form, can make FPC antenna body 20 angle parallel with pcb board 40 and laminating all applicable.Plastic rubber bracket 10 also can be made separately, in the mode being spirally connected or paste, is fixedly installed on mobile phone inner casing.
FPC antenna body 20 is close to plastic rubber bracket 10 and is arranged, and in one embodiment, FPC antenna body 20 use brush coatings stick on plastic rubber bracket 10.Kink 12 inwardly carries out elasticity bending, and elastic deformation occurs, and now plastic rubber bracket 10 is arranged on to pcb board 40 tops, utilizes the elastic force of kink, and the FPC antenna body 20 of being close to is pressed on pcb board 40.Generally speaking, it is upper that plastic rubber bracket 10 is fixed on hand set machine shell (scheming not shown), can be integrally formed with casing.
For guaranteeing the consideration that powered is good between FPC antenna body 20 and pcb board 40, a tin cream 30 can be set on pcb board 40, tin cream 30 is arranged on the contact position with FPC antenna body 20, like this, just can guarantee that FPC antenna body 20 can conduction not occur extremely, the impact of avoiding contact resistance to bring with pcb board 40.
In a preferred embodiment, the breeze way 124 of antenna holder 10 arranges positioning protrusion portion 14, and positioning convex portion 14 can be square, triangle or other suitable shape.FPC antenna body 20 arranges location hole in corresponding position, be used for making positioning convex portion 14 to pass wherein, thereby FPC antenna body 20 is played to horizontal fixation, avoid, when assembling, owing to being pasted not strongly, causing FPC antenna body 20 slippage from antenna holder 10.
Fig. 2 illustrates the FPC antenna assumption diagram of another specific embodiment of the present invention.In this embodiment, FPC antenna body 20 arranges a segmental arc 22, to avoid in bending process because FPC antenna body 20 bent no-load voltage ratio antenna holders 10 cause greatly producing relative displacement with antenna holder 10.
Those skilled in the art will appreciate that this technology can be applied to the circuit board apparatus of all application FPC antennas, be not only applied to mobile phone, also can be applied to other conventional electronic equipment.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection scope of the present invention.
