Specific embodiment

To make the purpose of this utility model, technical solution and advantage are clearer, with reference to the accompanying drawing to the utility model Embodiment is described in further detail.Obviously, described embodiment is a part of the embodiment of the utility model, rather than Whole embodiments.Based on described the embodiments of the present invention, those of ordinary skill in the art are without creative labor Every other embodiment obtained under the premise of dynamic, fall within the protection scope of the utility model.

Unless otherwise defined, the technical term or scientific term that the utility model uses are should be belonging to the utility model The ordinary meaning that personage in field with general technical ability is understood." first ", " second " used in the utility model and Similar word is not offered as any sequence, quantity or importance, and is used only to distinguish different component parts.In this reality With in novel description, it is to be understood that if there is the orientation or positional relationship of the instructions such as term " on ", "lower", "left", "right" To be based on the orientation or positional relationship shown in the drawings, it is merely for convenience of describing the present invention and simplifying the description, without referring to Show or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore in attached drawing The term for describing positional relationship only for illustration, should not be understood as the limitation to this patent, for the common of this field For technical staff, the concrete meaning of above-mentioned term can be understood as the case may be.

As shown in Figure 1, which show a kind of structural schematic diagrams of the connection structure of FPC and PCB provided by the utility model. The connection structure of the FPC and PCB includes being pressed on display module or FPC1 in touch module 100 and being fixed on casing 200 On PCB2, one end of the FPC1 is equipped with BTB plug 3, and the PCB2 is equipped with the BTB socket 4 cooperated with BTB plug 3；Institute State and be additionally provided with location hole 5 on FPC, the casing 200 is equipped with the positioning column 6 that cooperate with the location hole, the location hole 5 and The cooperation of positioning column 6 makes the BTB socket 3 and BTB plug 4 realize contraposition.

In this way, by being equipped with location hole 5, the corresponding setting positioning column 6 on casing 200, thus that will determine on FPC1 Position hole 5 effectively can easily realize the contraposition of BTB plug 3 and BTB socket 4, effectively solution pair when being sheathed on positioning column 6 Position difficult problem, improves production efficiency.Specifically, in the present embodiment, the quantity of the location hole 5 is two.In this way, by two After a location hole 5 is sheathed on positioning column 6, fixation of the FPC1 with respect to the position PCB2 can be effectively ensured, guarantee that BTB is inserted First 3 and the contraposition of BTB socket 4 fix, effectively improve assembly efficiency and assembling accuracy.

Further, in the present embodiment, as Figure 2-3, the FPC1 is equipped with the backwards to 3 side of BTB plug One stiffening plate 7.First stiffening plate is arranged corresponding to the BTB plug 3.In this way, it is possible to prevente effectively from BTB plug 3 damages FPC1.Specifically, the projected area of first stiffening plate 7 covers the BTB plug 3 and is arranged.Specifically, the FPC is backwards BTB plug side is additionally provided with the second stiffening plate 8, and shown second stiffening plate 51 can according to need partial face in setting FPC1 The maximum region of product.Specifically, as shown in figure 4, first stiffening plate 7 or annular, projected area is around described BTB plug 3 is arranged, on the one hand the annular that the first stiffening plate 7 is provided around the BTB plug 3 can be reduced by the first reinforcement The area of plate 7 reduces materials and production cost, reinforcing effect of first stiffening plate 7 to FPC1 can also on the other hand be effectively ensured, Effectively improve the quality of FPC1.In the present embodiment, first stiffening plate 7 and the second stiffening plate 8 are made of PI material, institute It states and is connected between the first stiffening plate 7 and the second stiffening plate 8 and the FPC1 using viscose glue.Further, in the present embodiment, such as Shown in Fig. 5, the two sides of the FPC1 are additionally provided with anti-tear copper wire 9, thereby may be ensured that the intensity of FPC1, are not torn easily It splits.
