Abstract
The utility model relates to a structure of a flexible circuit board, which belongs to electronics. The flexible circuit board and a mobile phone are provided with contact terminals for transmitting electronic signals, a plurality of signal connecting portions are arranged at preset positions on one side of the flexible circuit board, and the flexible circuit board can contact with the contact terminals on the mobile phone correspondingly by aids of the signal connecting portions, thereby realizing signal transmission. The structure can enlarge contact area of the signal connecting portions and the contact terminals, and can be manufactured via a simple mold and with low cost.
Description
Technical field
The utility model relates to electrical type, and particularly a kind of structure of flexible circuit board refers to a kind of structure that need not utilize raising point also can increase the flexible circuit board of contact area especially.
Background technology
As shown in Figure 1, connection status generalized section for the contact terminal of existing flexible circuit board and mobile phone, by learning among the figure, flexible circuit board 1 must be earlier in conjunction with plate body 2 to become SIM card, form plural concave point 10 in flexible circuit board 1 one sides, the another side then forms the salient point 12 that is produced because of concave point 10, and the contact terminal 30 corresponding contacts on the side that this flexible circuit board 1 will form concave point 10 and the mobile phone 3, yet this kind contact structures fall in the concave point 10 because of the contact terminal 30 less meetings of improper or some mobile phones in user's use, cause loose contact easily, make mobile phone 3 and flexible circuit board 1 present unsettled electric signal and be connected.
The problem of above-mentioned existence needs further to be improved.
The utility model content
The purpose of this utility model is to provide a kind of structure of flexible circuit board, solves mobile phone and the problem that unstable electric signal is connected occurs with flexible circuit board.
A kind of structure of flexible circuit board, this flexible circuit board and mobile phone are provided with the contact terminal that transmits for electric signal, wherein establish signal connecting portion plural and the corresponding contact of this contact terminal in this flexible circuit board in the weldering of the precalculated position of a predetermined side.
Wherein this signal connecting portion is a tin projection;
This signal connecting portion coating one coating layer wherein;
Wherein this coating layer is separator or strengthening layer;
Wherein this strengthening layer is nickel plating;
Wherein this separator is gold-plated.
Advantage of the present utility model is: this kind structure can significantly increase the contact area of signal connecting portion and contact terminal, and only need simple die and then save cost of manufacture, and reduce the incidence of loose contact, utilize nickel plating to strengthen the intensity that the signal connecting portion uses, utilize gold-plated to prevent the oxidation of signal connecting portion.
Description of drawings
Fig. 1 is the connection status generalized section of the contact terminal of existing flexible circuit board and mobile phone.
Fig. 2 is the schematic perspective view of the utility model preferred embodiment.
Fig. 3 is the coating state generalized section on the utility model signal connecting portion surface.
Fig. 4 is the user mode generalized section of the utility model preferred embodiment.
Embodiment
As accompanying drawing 2 to shown in the accompanying drawing 4, by can know among the figure find out flexible circuit board of the present utility model 4 must be earlier in conjunction with plate body 5 to become SIM card, and the set contact terminal 60 of flexible circuit board 4 and mobile phone 6 is for the electric signal transmission, wherein flexible circuit board 4 is established plural signal connecting portion 40 in the weldering of the precalculated position of a side, but also coating one deck coating layer 42 in signal connecting portion 40 surfaces, coating layer 42 can be separator or strengthening layer, utilize this signal connecting portion 40 can with contact terminal 60 corresponding contacts on the mobile phone 6 to reach the purpose that transmits signal.
By above-mentioned structure, form design, be to use situation to be described as follows with regard to the utility model, find out by knowing among the figure, because of signal connecting portion 40 must be inconsistent to reach the purpose that transmits signal with contact terminal 60, must be when being assembled in signal connecting portion 40 on the mobile phone 6 to a side shifting, can cause signal connecting portion 40 and contact terminal 60 mutual friction mutually this moment, finish the state that 40 of location back signal connecting portions and contact terminal 60 are in mutual extrusion for a long time, therefore signal connecting portion 40 is easy to damage and causes loose contact, so can be positioned at signal connecting portion 40 surface coated one deck coating layers 42, if with the coating strengthening layer is example, then can increase the intensity of signal connecting portion 40 on using, to reduce damage because of friction or extruding generation, if with the coating separator is example, then can promote the oxidation-protective effect of signal connecting portion 40, to prevent causing loose contact because of signal connecting portion 40 surface oxidations.
