Abstract
The present utility model provides an anti-tearing FPC. The FPC comprises a flexible substrate and a copper foil line printed on the flexible substrate, the flexible substrate comprises a basal part and an interface part for connecting with the basal part, a connecting place of the interface part and the basal part is arc-shaped, and a reinforcing rib is arranged on the arc-shaped connecting place. In the anti-tearing FPC, an arc-shaped pull wire is arranged on the connecting place of the basal part and the interface part of the FPC flexible substrate, external force is pulled to a vacancy far away from a line area, arc-shaped copper is added to protect, and the FPC can be effectively prevented from being torn.
Description
Technical field
The utility model relates to art of printed circuit boards, relates in particular to a kind of anti-FPC that tears.
Background technology
FPC is that the English of flexible printed circuit board (Flexible Printed Circuit Board) is called for short, it is a kind of circuit board with height reliability of making as base material take polyimides or polyester film, have the advantages such as distribution density is high, lightweight, thin thickness, be widely used in the electronic device field such as notebook computer, liquid crystal display, mobile phone, digital camera, aviation electronics.
As shown in Figure 1, structural representation for existing FPC, existing FPC comprises flexible base, board 11 and is printed in copper foil circuit 300 on the flexible base, board 100, this flexible base, board 100 comprises base portion 102 and is connected in the interface portion 104 of base portion, described base portion 102 is rectangular in shape with the junction 105 of interface portion 104, when external force is pullled FPC, External Force Acting is when the junction 105 of base portion 102 and interface portion 104, because the design of FPC is more and more thinner, square junction 105 is easy to damage because of pullling of external force, and then destroy copper foil circuit 300, cause the FPC disabler.
The utility model content
The purpose of this utility model is to provide a kind of anti-tear FPC, and its corner at the FPC flexible base, board arranges the arc draught line, and increases shop copper, effectively avoids FPC to be torn.
For achieving the above object, the utility model provides a kind of anti-tear FPC, comprise: flexible base, board and be printed in copper foil circuit on the flexible base, board, this flexible base, board comprises base portion and connects the interface portion of base portion, the junction of this interface portion and base portion is arc, and is provided with reinforcement in this arc junction.
Described arc is several sections interconnective circular arcs.
Described arc is a circular arc.
Described reinforcement is made of copper.
Described interface portion is provided with splicing ear.
The beneficial effects of the utility model: the anti-tear FPC that the utility model provides; it arranges the arc draught line at the base portion of FPC flexible base, board and the junction of interface portion; with external force traction to the room away from circuit zone, and increase arc and spread copper and do protection, effectively avoid FPC to be torn.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing, by embodiment of the present utility model is described in detail, will make the technical solution of the utility model and other beneficial effect apparent.
In the accompanying drawing,
Fig. 1 is the structural representation of existing FPC;
Fig. 2 is the structural representation of the anti-tear FPC of the utility model.
Embodiment
Technological means and the effect thereof taked for further setting forth the utility model are described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
See also Fig. 2, the anti-tear FPC that the utility model provides, comprise: flexible base, board 2 and be printed in copper foil circuit 4 on the flexible base, board, this flexible base, board 2 comprises base portion 22 and connects the interface portion 24 of base portion 22, this interface portion 24 is arc with the junction of base portion 22, and is provided with reinforcement 224 in this arc junction.
Described base portion 22 is used for wiring and installing electronic elements, and described interface portion 24 is provided with splicing ear 242, is used for being electrically connected with external device (not shown).
Described arc can be one section circular arc, elliptic arc also can be interconnective several sections circular arcs, elliptic arc, and preferred, described circular arc asks two ends interconnective circular arc.
Described reinforcement 224 is made of copper, and its corresponding described arc distributes, and with the protection junction, avoids copper foil circuit 4 to be torn.
In sum, the anti-tear FPC that the utility model provides, it arranges the arc draught line at the base portion of FPC flexible base, board and the junction of interface portion, with external force traction to the room away from circuit zone, and increase arc and spread copper and do protection, effectively avoid FPC to be torn.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model claim.
