Abstract
The utility model relates to the field of circuit board technology, especially relates to an anti-tearing FPC, comprising an L-shaped FPC main body. A hypotenuse and two R corners located at the two ends of the hypotenuse are molded at a corner position of the FPC main body, transitions between the two ends of the hypotenuse and the FPC main body are carried out respectively via the R corners. In the utility model, by employing a structure of the hypotenuse and the two R corners at the corner position to substitute an arc corner in the prior art, the stress at the corner position is reduced, and the FPC can be prevented from being torn. Moreover, because a copper block is arranged at the corner position of the FPC main body, the product intensity is reinforced, a stronger anti-tearing effect is achieved, and the product intensity requirement can be satisfied by using general materials, saving material cost.
Description
Technical field:
The utility model relates to the wiring board technical field, refers in particular to the anti-FPC that tears.
Background technology:
FPC (flexible PCB) is to be a kind of flexible printed circuit with height reliability that base material is processed with polyimides or polyester film.FPC has that distribution density is high, in light weight, the characteristics of thin thickness, mainly uses a lot of products at mobile phone, notebook computer, PDA, digital camera, LCM etc.
See shown in Figure 1; Because structural reason; Existing FPC has some and is designed to the L type and comes the fit end to use, but traditional design is just led a circular arc R around the corner, because the client can be to the stress of the F direction of corner location generation of FPC when using; When using the material of common FPC, be easy to occur the phenomenon of fracture in the position at turning.Common way is to use high-strength materials or uses multilayer material to improve the intensity of the corner of FPC, but cost can increase greatly, is unfavorable for market competition.
The utility model content:
The purpose of the utility model is exactly the deficiency that exists to prior art and provide a kind of and reduce corner's stress, reach the anti-FPC of tearing of strong tear-resistant effect, enhanced products intensity.
To achieve these goals; The technical scheme that the utility model adopts is: the anti-FPC that tears; Include L type FPC main body, the corner location of FPC main body forms hypotenuse and is positioned at two R angles at hypotenuse two ends, passes through the transition of R angle between the two ends of hypotenuse and the FPC main body respectively.
The corner location of said FPC main body is provided with copper billet.
The width of said copper billet is 1～5mm.
The angle of inclination of said hypotenuse is 45 degree.
The radius at said R angle is 5～8mm.
The utility model beneficial effect is: the anti-FPC of tearing that the utility model provides; Include L type FPC main body; The corner location of FPC main body forms hypotenuse and is positioned at two R angles at hypotenuse two ends, and respectively through the transition of R angle, the utility model adopts the structure at hypotenuse and two R angles to replace arc chord angle of the prior art around the corner between the two ends of hypotenuse and the FPC main body; Reduce the stress of corner, can prevent that FPC from being torn; And the corner location of FPC main body is provided with copper billet, and the intensity of enhanced products reaches stronger tear-resistant effect, uses common material just can satisfy the requirement of strength of product, has saved material cost.
Description of drawings:
Fig. 1 is the structural representation of existing FPC;
Fig. 2 is the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See shown in Figure 2; The utility model includes L type FPC main body 1; The corner location of FPC main body 1 forms hypotenuse 11 and is positioned at two R angles 12 at hypotenuse 11 two ends, passes through 12 transition of R angle between the two ends of hypotenuse 11 and the FPC main body 1 respectively.The corner location of FPC main body 1 is provided with copper billet 2.The width of copper billet 2 is 1～5mm, and in this execution mode, the width of copper billet 2 is 1.5mm.The angle of inclination of hypotenuse 11 is 45 degree.The radius at R angle 12 is 5～8mm, and the radius at R angle 12 is 6mm in this execution mode.The intensity of the stress that produces when the radius at hypotenuse 11 length, R angle 12 and the width of copper billet 2 use according to reality is come fixed.
The utility model adopts the structure at hypotenuse 11 and two R angles 12 to replace arc chord angle of the prior art around the corner, reduces the stress of corner, can prevent that FPC from being torn; And the corner location of FPC main body 1 is provided with copper billet 2, and the intensity of enhanced products reaches stronger tear-resistant effect, uses common material just can satisfy the requirement of strength of product, has saved material cost.
Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
