Embodiment

Various exemplary embodiments of the present utility model are described in detail now with reference to accompanying drawing.It should be noted that：It is unless another Illustrate outside, the part and the positioned opposite of step, numerical expression and numerical value otherwise illustrated in these embodiments is unlimited The scope of the utility model processed.

The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below New and its application or any restrictions used.

It may be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in appropriate situation Under, the technology and equipment should be considered as part for specification.

In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without It is as limitation.Therefore, other examples of exemplary embodiment can have different values.

It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.

With reference to figure 1, Fig. 2, the utility model provides a kind of FPC plates, successively including the first elastic insulator 1, electric conductor 3rd, the second elastic insulator 2；Electric conductor 3 is folded between the first elastic insulator 1 and the second elastic insulator 2, and three can be with It is combined with each other by way of hot pressing, so as to form FPC plates.First elastic insulator 1, the conduct of the second elastic insulator 2 The base material of FPC plates, it is made of the material of elasticity so that it has certain stretcher strain ability.

First elastic insulator 1, the second elastic insulator 2 can use plastic cement well-known to those skilled in the art, silicon Glue etc. has material of certain deformability etc..Wherein, the first elastic insulator 1, the second elastic insulator 2 material can phase Together, can also be different, no longer illustrate herein.

Electric conductor 3 of the present utility model can use copper foil material well-known to those skilled in the art, and electric conductor 3 can be with It is provided with one or more of, it has certain conductive pattern so that the FPC plates can play a part of conducting.Electric conductor 3 Extend along the length direction of the first elastic insulator 1, the second elastic insulator 2, and electric conductor 3 is in their extension direction at least It is in partly bending.

That is, electric conductor 3 of the present utility model is not linear in their extension direction, but in bending Shape, this bending can be regular or irregular；Such as it is serrated；Preferably corrugated, so as to prevent Only corner position or the stress concentration of bending position, avoid the position from being broken in drawing process.

Because electric conductor 3 is forniciform in the direction that it extends, this allows for causing the first bullet stretching whole FPC plates Property insulator 1, the second elastic insulator 2 while deform, it is empty that forniciform electric conductor 3 gives itself certain deformation Between so that electric conductor 3 is not easy to be pulled off, so as to improve FPC reliability.

In one specific embodiment of the utility model, the first elastic insulator 1, the thickness of the second elastic insulator 2 It can be respectively 50 μm, the thickness of electric conductor 3 can be 12 μm to 18 μm.When using hot-forming, preferably in the first bullet Property insulator 1, the hot-pressed surface of the second elastic insulator 2 paste one layer of reinforcing mould release membrance, such as PET mould release membrances respectively, so as to First elastic insulator 1, the elastic deformation of the second elastic insulator 2 when can avoid hot pressing.After pressing terminates, by the first bullet Property insulator 1, the PET mould release membrances on the surface of the second elastic insulator 2 are torn, so as to obtain FPC plates of the present utility model.

FPC plates of the present utility model may apply in electronic product, therefore, with reference to figure 3, the utility model provides one Kind electronic product, it includes housing a and the circuit board (view does not provide) in housing a, in addition to be connected with housing a Variant part b, is provided with above-mentioned FPC plates in variant part b, and the electric conductor 3 in FPC plates is together with circuit board conducting.

Fig. 3 is illustrated that a kind of intelligent watch, and the circuit board of the intelligent watch is integrated with housing a, and variant part b is then hand The watchband of table.Now FPC plates can use as the extended line of antenna.That is, the main day of wrist-watch is provided with circuit board Line, but the volume of housing is limited to, the size of primary antenna can not meet requirement.

Therefore FPC plates can be turned on the primary antenna on circuit board, and the remainder of FPC plates is hidden in watchband so that FPC plates can use as the extended line of primary antenna；And user is when wearing, it is ensured that the FPC plates in watchband are not It can be pullled disconnected, ensure that the reliability of product.

For a person skilled in the art, electronic product can also be intelligent glasses, and now, housing a can be eye Cell mount, it has been internally integrated circuit board of intelligent glasses etc.；Variant part b is then temple portion.Now, FPC plates are integrated in In leg of spectacles, it can both be used as the extended line of antenna, can also be as the effect of common signal conduction, herein no longer Illustrate.

So, by by the stretchable FPC plates arrangement position being easily stretched in the product, and this is stretchable FPC plates are connected with circuit board, make its signal wire as this circuit board, so as to reduce because stretching causes signal wire in product The probability of the generation of damage, improve the reliability of product.

Although some specific embodiments of the present utility model are described in detail by example, this area It is to be understood by the skilled artisans that above example merely to illustrate, rather than in order to limit the scope of the utility model.This Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case of, to above example Modify.The scope of the utility model is defined by the following claims.
