Wire between the conductor layer of existing flexible PCB is juxtaposed flat conductor, the direct gap of the main traverse line on both sides and central conductor is generally 0.6mm, in juxtaposition harness wiring, due to the small displacement of flat conductor, scrap with regard to being easy to cause the direct contact short circuit of two main traverse lines and central conductor; Meanwhile, the separation of not insulating of the main traverse line on both sides and central conductor, in the use procedure of soft lamp band, the especially soft lamp band of high pressure, dispelling the heat badly causes thermal breakdown to cause the direct contact short circuit of two main traverse lines and central conductor and scraps.
Utility model content
For above-mentioned prior art present situation, technical problem to be solved in the utility model is, a kind of flexible PCB is provided and has the soft lamp band of LED of this flexible PCB, it can avoid main traverse line and central conductor because small displacement or thermal breakdown in harness wiring cause short circuit.
In order to solve the problems of the technologies described above, a kind of flexible PCB provided by the utility model, comprise conductor layer, be arranged at the insulating barrier and the solder mask that is arranged at described conductor layer opposite side of described conductor layer one side, described conductor layer is provided with the fracture for potted element, on described solder mask, be provided with the window corresponding with described fracture, described conductor layer comprises from described insulating barrier to described solder mask successively stacked trunk conductor layer, isolating separator layer and return wire layer, described trunk conductor layer comprises two juxtaposed flat trunk wires, described return wire layer comprises at least one flat return wire, described flat return wire and two described flat trunk wires are electrically connected and form major loop, on described return wire layer, be provided with described fracture.
In an embodiment, described flat return wire is more than two therein, all described flat return wire juxtapositions.
In an embodiment, between each described flat return wire, mutually insulated is separated therein.
In an embodiment, on each described flat return wire, be provided with described fracture therein; Or form described fracture between two adjacent described flat return wires.
In an embodiment, the two ends of described flat return wire are respectively electrically connected with two described flat trunk wires by conductive rivet therein.
In an embodiment, the width of described return wire layer is less than the width of described solder mask and described insulating barrier therein.
In an embodiment, described solder mask is formed by the mode that sprays welding resistance paint on described conductor layer therein.
The soft lamp band of a kind of LED provided by the utility model, comprises flexible PCB and multiple LED lamp pearl, and described flexible PCB is above-mentioned flexible PCB, and multiple described LED lamp bead seals are contained in described incision position.
Compared with prior art, flexible PCB of the present utility model and there is the soft lamp band of LED of this flexible PCB, because trunk conductor layer and the return wire layer of flexible PCB carry out insulation processing by isolating separator layer, make trunk conductor layer and return wire layer can not cause short circuit because of small displacement or thermal breakdown in harness wiring, therefore functional, circuit reliability is high, and the life-span is long.
The beneficial effect that the utility model additional technical feature has will describe in this specification embodiment part.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of the flexible PCB in one of them embodiment of utility model.
Description of reference numerals: 10, insulating barrier; 20, conductor layer; 21, flat trunk wire; 22, isolating separator layer; 23, flat return wire; 30, solder mask; 40, conductive rivet; 50, LED lamp pearl.
Embodiment
Also the utility model is elaborated below with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in following embodiment and embodiment can combine mutually.
As shown in Figure 1, flexible PCB in one of them embodiment of the utility model comprises conductor layer 20, be arranged at the insulating barrier 10 and the solder mask 30 that is arranged at described conductor layer 20 opposite sides of described conductor layer 20 1 sides, described conductor layer 20 comprises from described insulating barrier 10 to described solder mask 30 successively stacked trunk conductor layer, isolating separator layer 22 and return wire layer, described trunk conductor layer comprises two juxtaposed flat trunk wires 21, described return wire layer comprises at least one flat return wire 23, described flat return wire 23 and two described flat trunk wires 21 are electrically connected and form major loop, on described return wire layer, be provided with fracture (not shown), on described solder mask 30, be provided with the window (not shown) corresponding with described fracture.
Flexible PCB of the present utility model, because trunk conductor layer and the return wire layer of flexible PCB carry out insulation processing by isolating separator layer 22, make trunk conductor layer and return wire layer can not cause short circuit because of small displacement or thermal breakdown in harness wiring, therefore functional, circuit reliability is high, and the life-span is long.
