The flexible circuit board and the electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 5, an embodiment of the present application discloses a flexible circuit board, which may be applied to an electronic device, so that components contained in the electronic device are electrically connected to a main board or a sub-board of the electronic device through the flexible circuit board. The flexible circuit board may include a main body portion 100 and a bending portion 200, a first end of the main body portion 100 is provided with a first electrical connector 110, a second end of the main body portion 100 is connected to a third end of the bending portion 200, the main body portion 100 and the bending portion 200 may adopt an integrated structure, or may be connected after being separately disposed, and the main body portion 100 may further adopt a multi-section structure, and the bending portion 200 may further adopt a multi-section structure. The body portion 100 is provided with a first lug 120 and a second lug 130. The first electrical connector 110 is used to electrically connect the main body 100 to a main board or a sub-board, and the first electrical connector 110 may be a board-to-board electrical connector or other connection structure having an electrical connection function, which is not limited in the embodiment of the present application. The first lug 120 and the second lug 130 each project relative to the main body portion 100 and are disposed opposite to each other in a width direction of the main body portion 100, where the width direction is perpendicular to a direction in which the first end of the main body portion 100 extends toward the second end. The bending portion 200 is bent relative to the main body portion 100 and overlaps the main body portion 100, a second electrical connector 210 is disposed at a fourth end of the bending portion 200, and the second electrical connector 210 may be a board-to-board electrical connector or other connection structures with an electrical connection function, which is not limited in this embodiment of the present invention. The two side edges of the bent portion 200 are respectively engaged with the first lug 120 and the second lug 130 in a limiting manner, and the bent portion 200 is separable from the first lug 120 and the second lug 130, so that the distance between the first electrical connector 110 and the second electrical connector 210 is adjustable. That is, at least a portion of the bending part 200 may be in limit fit with the first lug 120 and the second lug 130, so that the first lug 120 and the second lug 130 may limit the position of the bending part 200, so that the entire flexible circuit board may maintain a predetermined length, and at the same time, the at least a portion of the bending part 200 may be separated from the first lug 120 and the second lug 130, so that the first lug 120 and the second lug 130 no longer limit the position of the bending part 200, so that an operator may adjust the shape and position of the bending part 200 to change the distance between the first electrical connector 110 and the second electrical connector 210, and finally achieve the purpose of changing the length of the entire flexible circuit board. The arrangement enables the universality of the flexible circuit board to be higher, so that the flexible circuit board can be adapted to different design requirements.

In the embodiment of the present application, the bending part 200 of the flexible circuit board is in limit fit with the first lug 120 and the second lug 130, and the bending part 200 is separable from the first lug 120 and the second lug 130, so that the distance between the first electrical connector 110 and the second electrical connector 210 is adjustable, thereby meeting the installation requirements of different parts. After the scheme is adopted, the whole length of the same flexible circuit board can be changed, so that the same flexible circuit board can be adapted to different parts, the flexible circuit boards with different lengths do not need to be processed aiming at different parts, the number of the flexible circuit boards with different specifications can be reduced, and the flexible circuit boards do not need to be selected by spending too much time when the parts are installed. Therefore, the embodiment can solve the problems of high manufacturing cost and low assembly efficiency of the electronic equipment.

The first lug 120 and the second lug 130 may be disposed at a part of the main body 100, in this case, the first lug 120 and the second lug 130 may adopt a column structure, and the bending portion 200 may be provided with a limiting hole corresponding to the column structure, so that the limiting is achieved by the matching of the limiting hole and the first lug 120 and the second lug 130. However, when the position-limiting method is adopted, the fitting area between the first lug 120 and the second lug 130 and the bending part 200 is small, so that the position-limiting effect is poor, and the bending part 200 is easily damaged. Accordingly, the first lug 120 may have a first sliding slot 121, the second lug 130 may have a second sliding slot, both the first sliding slot 121 and the second sliding slot extend along the extending direction of the main body portion 100, and both side edges of the bending portion 200 are respectively in sliding fit with the first sliding slot 121 and the second sliding slot. In this embodiment, the first sliding groove 121 and the second sliding groove are longer, so that the matching area between the first sliding groove 121 and the bent portion 200 is larger, so as to improve the position limiting effect, prevent the bent portion 200 from being damaged, and further reinforce the main body portion 100. Meanwhile, the embodiment uses the edge of the bending part 200 to realize the position limitation, and there is no need to provide other structures on the bending part 200, so that the forming process of the bending part 200 can be simplified. In addition, the first sliding groove 121 and the second sliding groove can play a guiding role, and an operator pulls one end of the bending part 200 to slide, so that the length of the flexible circuit board can be stably and reliably changed, and the situation of deflection and the like is not easy to occur.

Optionally, the first lug 120 and the second lug 130 may be disposed at positions of the main body 100 away from the edges thereof, and a distance between the first lug 120 and the second lug 130 is smaller than a distance between two side edges of the main body 100, which results in that the width of the bending portion 200 is smaller than the width of the main body 100, thereby reducing an available area of the bending portion 200, which is not favorable for circuit layout. To solve this problem, in other embodiments, the first lug 120 extends from one side edge of the main body portion 100, the first lug 120 is bent relative to the main body portion 100 to form a first sliding slot 121, the second lug 130 extends from the other side edge of the main body portion 100, and the second lug 130 is bent relative to the main body portion 100 to form a second sliding slot. Since the first lug 120 and the second lug 130 are disposed at the edge of the main body portion 100, the width of the bending portion 200 may be substantially equal to the width of the main body portion 100, and the available area of the bending portion 200 is larger, which is more favorable for circuit layout.

In an alternative embodiment, the first lug 120 and the second lug 130 each extend from a first end to a second end. In other words, the first lug 120 and the second lug 130 are disposed by fully utilizing the entire edge of the main body portion 100, so that the lengths of the first lug 120 and the second lug 130 are as large as possible, thereby increasing the matching area of the bending portion 200 and the first lug 120 and the second lug 130, and further improving the limiting effect and the guiding effect.

Alternatively, the first electrical connector 110 and the second electrical connector 210 may be located on the same side of the flexible circuit board, or the first electrical connector 110 and the second electrical connector 210 may be located on different sides of the flexible circuit board, and the latter arrangement is relatively more adaptable to the arrangement position of the components. At this time, the bending portion 200 includes a first bending section 220 and a second bending section 230, the main body portion 100, the first bending section 220 and the second bending section 230 are sequentially stacked, the second bending section 230 is connected to the main body portion 100 through the first bending section 220, and the second electrical connector 210 is disposed at one end of the second bending section 230 away from the first electrical connector 110, so that the first electrical connector 110 and the second electrical connector 210 are located at different sides of the flexible circuit board.

In a further embodiment, the flexible circuit board further includes a fixing member 300, and the bending part 200 is fixedly connected to at least one of the first lug 120 and the second lug 130 through the fixing member 300 when the distance between the first electrical connector 110 and the second electrical connector 210 reaches the target distance. It should be noted that the distance between the first electrical connector 110 and the second electrical connector 210 reaching the target distance means that the positions of the first electrical connector 110 and the second electrical connector 210 are matched with the positions of the target component and the main board or the sub-board, in which case, the target component may be connected to the main board or the sub-board through the flexible circuit board. At this time, the bending part 200 and at least one of the first lug 120 and the second lug 130 are fixed by the fixing member 300, so that the position of the bending part 200 can be limited, and the bending part 200 is prevented from being deformed and moved during the use of the flexible circuit board, thereby preventing the flexible circuit board from being damaged and improving the electrical connection reliability of the components.

The fixing member 300 may be a fastener or other component having a fixing function, and in order to facilitate the operation and reduce the space occupied by the fixing member 300, the fixing member 300 may be configured as an adhesive member, the adhesive member has a first adhesive surface and a second adhesive surface that are opposite to each other, the second adhesive surface is provided with a separable covering layer, the separable covering layer may be adhered to the second adhesive surface, and the surface of the separable covering layer that is away from the second adhesive surface has no viscosity, so that the bending portion 200 moves relative to the main body portion 100. Alternatively, the adhesive member may be a double-sided tape. When the adhesive is used, the first adhesive surface is adhered to one of the first lug 120 and the bending part 200, and when the distance between the first electrical connector 110 and the second electrical connector 210 reaches the target distance, the separable covering layer is separated from the second adhesive surface, and the bending part 200 is adhered to the first lug 120 through the second adhesive surface, so that the bending part 200 is fixed to the first lug 120. Similarly, the first adhesive surface of the adhesive is adhered to one of the second lug 130 and the bending part 200, and when the distance between the first electrical connector 110 and the second electrical connector 210 reaches the target distance, the separable covering layer is separated from the second adhesive surface, and the bending part 200 is adhered to the second lug 130 through the second adhesive surface, so that the fixing between the bending part 200 and the second lug 130 is achieved. The adhesive member in this embodiment is thin, so that it occupies a small space; at the same time, the operator only needs to remove the detachable cover layer to achieve the bonding operation, so that the bonding piece is more convenient for the user to operate.

The fixing member 300 is disposed at various positions, and in one embodiment, as shown in fig. 5, the fixing member 300 is disposed between the side surface of the bending portion 200 and the first lug 120. Since the distance between the side of the bending part 200 and the first lug 120 is not substantially changed, even if the portion where the bending part 200 is engaged with the first lug 120 is changed, the fixing member 300 cannot be brought into contact with the first lug 120 or the bending part 200, and thus the embodiment can more reliably realize the fixing between the bending part 200 and the first lug 120. Similarly, the fixing member 300 is disposed between the side surface of the bending part 200 and the second lug 130, so that the fixing between the bending part 200 and the second lug 130 is more reliably achieved.

In another alternative embodiment, as shown in fig. 6, a fixing member 300 is disposed between a surface of the bending portion 200 facing away from the main body portion 100 and the first lug 120. Since the surface of the bending part 200 facing away from the main body 100 is more easily seen by the operator, the operator can more easily connect the fixing member 300 to the bending part 200 or the first lug 120. Similarly, the fixing member 300 is disposed between the surface of the bending part 200 departing from the main body 100 and the second lug 130, so that the user can conveniently connect the fixing member 300 with the bending part 200 or the second lug 130.

It should be noted that, when the fixing member 300 is an adhesive member, a first surface of the adhesive member may be adhered to the first lug 120 or the second lug 130, and when the distance between the first electrical connector 110 and the second electrical connector 210 reaches a target distance, the second adhesive surface is exposed and faces the bending portion 200, so as to be adhered to the bending portion 200; alternatively, the first surface of the adhesive member may be adhered to the bending part 200, and in a case where the distance between the first electrical connector 110 and the second electrical connector 210 reaches a target distance, the second adhesive surface is exposed and faces the first lug 120 or the second lug 130, so as to be adhered to the first lug 120 or the second lug 130.

Alternatively, the first lug 120 and the second lug 130 may be provided separately from the main body portion 100, and the first lug 120 and the second lug 130 may be connected to the main body portion 100 by bonding or the like, and at this time, the first lug 120 and the second lug 130 are both rigid structures, so that the first lug 120 and the second lug 130 have higher structural strength, and thus, a better reinforcing effect is generated on the main body portion 100. Alternatively, the first lug 120 and the second lug 130 are integrally formed with the main body portion 100, and the material for manufacturing the first lug 120 and the second lug 130 may be the same as the material for manufacturing the main body portion 100, so as to facilitate the molding of the flexible circuit board. Of course, when the first lug 120 and the second lug 130 are provided separately from the main body portion 100, the material of the first lug 120 and the second lug 130 may be the same as that of the main body portion 100, and the embodiment of the present application does not limit this.

The embodiment of the application also discloses electronic equipment which comprises the flexible circuit board in any embodiment.

The electronic device disclosed in the embodiment of the present application may be an electronic device such as a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), and an electronic game machine, and the kind of the electronic device is not particularly limited in the embodiment of the present application.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
