The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0028] Example 1

[0029] Please see Figure 1 and Figure 4 A foldable flexible circuit board includes: a flexible circuit board body 1 and multiple support members;

[0030] The flexible circuit board body 1 includes a flexible board body 11, and a plurality of through holes 12 are provided along the edge of the surface of the flexible board body 11;

[0031] Multiple support members are respectively disposed on both sides of the flexible circuit board body 1. Multiple support members are disposed at equal intervals at the bending points of the flexible circuit board body 1, and there is a gap between two adjacent support members.

[0032] Based on the above, the support member provides support for the flexible circuit board body 1, preventing the flexible circuit board body 1 from breaking during the folding process.

[0033] like Figures 1-3 as well as Figure 5As shown, the support includes a connector 2, which is fixed to the side of the flexible plate body 11 by a fixing screw 3. The fixing screw 3 passes through the through hole 12. A support block 4 is provided between the upper and lower connectors 2. The connector 2 includes a prism block 21, which is provided on the side of the flexible plate body 11. A first limiting plate 22 and a second limiting plate 24 are provided on the side facing the flexible plate body 11. The flexible plate body 11 is located between the first limiting plate 22 and the second limiting plate 24. The vertical cross-section of the prism block 21 is a polygon other than a triangle.

[0034] The first limiting plate 22 has a mounting hole 23 on the surface facing the flexible plate body 11, and the second limiting plate 24 has a first threaded hole 25 on the surface facing the flexible plate body 11. The fixing screw 3 passes through the mounting hole 23 and the through hole 12 and is threadedly connected to the first threaded hole 25.

[0035] Based on the above, the support member plays the role of supporting the flexible plate body 11. The connector 2 is fixed at the edge of the flexible plate body 11 by the cooperation of the fixing screw 3, the first limiting plate 22 and the second limiting plate 24. The connector 2 moves together when the flexible plate body 11 is bent.

[0036] like Figure 6 As shown, the support block 4 includes a block body 41, and the upper and lower sides of the block body 41 are provided with second threaded holes 42, which are adapted to the fixing screws 3.

[0037] Based on the above, the support block 4 is fixed between the upper and lower connecting parts 2 by the threaded connection of the fixing screw 3, which achieves the effect of secondary support.

[0038] Example 2

[0039] Based on Embodiment 1, multiple connectors 2 are provided only on the outer edge of the flexible plate body 11 at the fold. When the flexible plate body 11 is bent, the multiple connectors 2 move together and are distributed in a ring at equal intervals. The two adjacent connectors 2 are tightly fitted together. At this time, the two adjacent connectors 2 support each other to avoid the situation where the fold is bent too much and breaks.

[0040] Example 3

[0041] Based on Embodiment 1, multiple connectors 2 are provided on the outer edge of the flexible plate body 11 away from the folding point, and a support block 4 is provided between the upper and lower connectors 2. The support block 4 supports the flexible plate body 11 away from the folding point, so that the folding point cannot be bent further.

[0042] In summary, the foldable flexible circuit board, through the cooperation between the support block 4 and the connector 2, enables the flexible board body 11 to be supported when folded, thereby avoiding breakage during the folding process.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
