Abstract
The utility model discloses a flexible printed circuit board, which comprises a conducting layer and an insulating layer, wherein the conducting layer is arranged on a base plate and the insulating layer is bonded on the surface of the conducting layer. Connecting fingers for inserting a connector are arranged at one end of the base plate. Openings keeping the connecting fingers exposed outside are arranged at the same end of the insulating layer. The flexible printed circuit board additionally comprises a fixed frame which can be arranged at the external part of the connector in a fastening way. One side of the fixed frame is fixed at the other end part of the connecting fingers. The utility model can greatly improve the stability and the reliability after being assembled with the connector.
Description
Technical field
The utility model relates to printed circuit technique, relates in particular to a kind of flexible printed circuit board.
Background technology
Flexible printed circuit board (FlexiblePrinted Circuit, FPC) be the printed circuit made from flexible insulating substrate, because it can free bend, coiling, folding etc., has the incomparable flexibility of printed circuit board (PCB), and has obtained application more and more widely.With reference to figure 1, FPC of the prior art generally comprises conductive layer 12 that is arranged on the substrate 11 and the insulating barrier 13 that is bonded in described conductive layer 12 surfaces, end at described substrate 11 is provided with the golden finger 14 that is used to insert connector, and the same end of described insulating barrier 13 is provided with the end that makes described golden finger 14 and is exposed to outer opening.The defective of this FPC structure is; as shown in Figure 2; only depend on the pressing of golden finger 14 to be connected between FPC10 and the connector 20; its periphery is without any protection structure or draw-in groove securing member, thereby, after FPC10 assembles with connector 20; under the effect of use or vibration external force; connector 20 is easy to become flexible with contacting of FPC10, thereby directly causes FPC10 and connector 20 to break away from, and influences this connector reliability of structure.
The utility model content
Technical problem to be solved in the utility model is: a kind of flexible printed circuit board is provided, this flexible printed circuit board can improve greatly with connector assembling after stability.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of flexible printed circuit board, include conductive layer that is arranged on the substrate and the insulating barrier that is bonded in described conductive layer surface, end at described substrate is provided with the golden finger that is used to insert connector, and the same end of described insulating barrier is provided with the end that makes described golden finger and is exposed to outer opening, this flexible printed circuit board also includes one can detain the fixed frame of being located at described connector outside, one side the other end that is fixed on described golden finger of described fixed frame.
The beneficial effects of the utility model are:
Embodiment of the present utility model is being by being provided with a fixed frame that is buckled on the connector on the FPC, thus that improve greatly and the stability connector assembling, and after its assembling, unless hand disassembly, general non-artificial external force can not be separated it with connector.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the structure vertical view of flexible printed circuit board in the prior art.
Fig. 2 is that flexible printed circuit board is assembled to state vertical view behind the connector in the prior art.
Fig. 3 is the structure vertical view of the embodiment of flexible printed circuit board that provides of the utility model.
Fig. 4 is the state vertical view after embodiment of flexible printed circuit board that the utility model provides is assembled to connector.
Embodiment
With reference to figure 3 and Fig. 4, this figure is the structure vertical view of the embodiment of flexible printed circuit board that provides of the utility model; As shown in the figure, present embodiment mainly includes conductive layer 12 that is arranged on the substrate 11 and the insulating barrier 13 that is bonded in conductive layer 12 surfaces, end at substrate 11 is provided with the golden finger 14 that is used to insert connector 200, and the same end of insulating barrier 13 is provided with the end that makes golden finger 14 and is exposed to outer opening, in addition, unlike the prior art be, present embodiment also includes one can detain the fixed frame 15 of being located at connector 200 outsides, one side the other end that is fixed on golden finger 14 of fixed frame 15 and overlap with it.
During specific implementation, can be according to the structure and the size of connector 200, the fixed frame 15 of design size and its coupling makes it can closely cooperate after the assembling.
During specific implementation; described fixed frame 15 can be made by the flexible parent metal that can turn up; during assembling; earlier loop configuration is turned up, made the end of golden finger 14 insert connector 200, then fixed frame 15 is put down the connector 200 that links closely and get final product as common FPC10; its the assembling after as shown in Figure 4; the connection of FPC100 not only has inner pressing like this, also has outside protection, makes connection more firm.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
Claims (2)
1. flexible printed circuit board, include conductive layer that is arranged on the substrate and the insulating barrier that is bonded in described conductive layer surface, end at described substrate is provided with the golden finger that is used to insert connector, and the same end of described insulating barrier is provided with the end that makes described golden finger and is exposed to outer opening, it is characterized in that, this flexible printed circuit board also includes one can detain the fixed frame of being located at described connector outside, one side the other end that is fixed on described golden finger of described fixed frame.
