The FPC for the mobile phone antenna is simple in structure and easy in mounting, the production cost of a mobile phone is reduced, and meanwhile, the volume of the mobile phone is reduced, so that the external arrangement of the mobile phone antenna is avoided, and the appearance of the mobile phone is enabled to be smaller and more delicate.
Description
Technical field
The utility model relates to a kind of flexible PCB, particularly relates to a kind of FPC that is used for antenna for mobile phone.
Background technology
FPC; Promptly " Flexible Printed Circuit " claims flexible PCB again, is called for short soft board; Be a kind ofly to have a height reliability with what polyimides or polyester film were that base material is processed; Excellent flexible printed circuit has that distribution density is high, in light weight, the characteristics of thin thickness, is mainly used in many products such as mobile phone, notebook computer, PDA, digital camera, LCM.Than PCB (Printed Circuit Board) is printed circuit board; FPC have assembling man-hour short, volume ratio PCB is little, weight ratio PCB light, thickness is than advantages such as PCB are thin; In the installation of electronic product, can save the connection work of unnecessary winding displacement; Can effectively reduce the volume of electronic product and increase the convenience that it carries, reduce the weight and the pliability that improves substrate of final products simultaneously, strengthen doing tridimensional assembling in the confined space.As in mobile phone, FPC can effectively save small product size with in light weight and thin thickness and be connected battery, microphone and button easily and be integral; In computer and liquid crystal screen, can digital signals be changed into picture through the one line configuring of utilizing FPC, see through liquid crystal screen and appear; In discman, utilize the three-dimensional space assembling characteristic of FPC huge CD to be changed into the good companion who carries; In disk drive, no matter hard disc or soft dish all very rely on the highly-flexible degree of FPC and the ultrathin of 0.1mm, accomplish the data that reads fast.
Though FPC original more application in mobile phone; But because the little characteristic of the volume of mobile phone own; Many mobile phones all have the problem that mobile phone speaker influences the reception of antenna for mobile phone; General mobile-phone manufacturers be in mobile phone inside through let loud speaker and antenna away from method solve, but the method is because so the inner space of mobile phone own is limited poor effect.What another kind of mode adopted is the external influence of eliminating loud speaker to antenna for mobile phone of antenna; Though the method can partly solve the problem that the loud speaker potato masher antenna receives; But external antenna not only can cause the not attractive in appearance of mobile phone; And along with mobile phone trends towards the developing direction of small and exquisite exquisiteness, the external method of antenna will certainly progressively be eliminated.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of FPC that is used for antenna for mobile phone, through being set, FPC efficiently solves the influence of loud speaker to antenna for mobile phone on the PCB body, practiced thrift the mobile phone inner space, make mobile phone smaller and more exquisite, exquisite.
The disclosed a kind of FPC that is used for antenna for mobile phone of the utility model; Comprise PCB body, antenna, FPC, lead and tie point; Described PCB body is provided with antenna, and antenna is connected with the PCB body through lead, and described lead is arranged on the FPC; The end of described FPC is connected with the PCB body through tie point, and the other end is connected with antenna.
The disclosed a kind of a kind of improvement that is used for the FPC of antenna for mobile phone of the utility model, described lead is provided with inductance element.
The disclosed a kind of a kind of improvement that is used for the FPC of antenna for mobile phone of the utility model, described inductance element is connected on the lead.
The disclosed a kind of a kind of improvement that is used for the FPC of antenna for mobile phone of the utility model, the connected mode of described FPC and PCB body is welding or grafting.
Disclosed a kind of another improvement that is used for the FPC of antenna for mobile phone of the utility model, the connected mode of described FPC and antenna is welding or grafting.
The disclosed a kind of FPC that is used for antenna for mobile phone of the utility model through being arranged on the inductance element of connecting on lead and the lead on the FPC, can effectively increase the high-frequency resistance on this path; Thereby suppress high-frequency current flowing on this path; Reach and reduce the purpose of loud speaker, and because this path low-frequency impedance is very little, therefore the audio signal to loud speaker can not exert an influence antenna for mobile phone influence; On the other hand; Because FPC announcement welding or the mode of pegging graft are connected with the PBC body, can effectively reduce capacitance profile, and then reduce the influence of loud speaker to antenna for mobile phone.The utility model is simple in structure, installs easily, has reduced the production cost of mobile phone, has reduced the volume of mobile phone simultaneously, has avoided the external of antenna for mobile phone, makes the outward appearance of mobile phone smaller and more exquisite, exquisite.
