Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit boards, in particular to an antistatic flexible FPC circuit board. Background Art

[0002] Antistatic flexible FPC circuit board is a special electronic component that combines the antistatic properties of flexible printed circuits. FPC circuit board is a circuit board that uses a flexible substrate (such as polyimide film, polyester film, etc.) as a base, and prints or attaches functional components such as wires and fine wires on the substrate through a special manufacturing process. Compared with traditional rigid circuit boards, FPC has better flexibility, scalability, light weight, and small size, and is suitable for use in scenarios with limited weight and volume.

[0003] Upon investigation, the Chinese utility model patent with publication number CN220673008U discloses a plug-in flexible circuit board, including a first flexible circuit board and a second flexible circuit board, the first flexible circuit board and the second flexible circuit board are plugged together; the first flexible circuit board is provided with a limit mechanism on both sides, the limit mechanism is rotatably arranged on both sides of the first flexible circuit board, and the second flexible circuit board is provided with a limit hole on both sides, and the limit hole corresponds to the limit mechanism. The above-mentioned flexible circuit board limit mechanism can be switched to a locked state or an unlocked state, so that the first flexible circuit board and the second flexible circuit board can be detachably connected.

[0004] However, the above-mentioned flexible circuit board itself is extremely light and thin. When adjusting the state of the limit mechanism by setting, it is necessary to first find the position of the corresponding mechanism, then operate the limit mechanism device to switch the state, and then perform the connection or separation operation. After completion, the limit mechanism needs to be manually reset. For flexible circuit boards that need to be set in a small space or complex structure, such as the flexible circuit boards in the internal structure of a mobile phone, the above operations are too cumbersome for installation or maintenance, and are not convenient to use.

[0005] Therefore, the utility model provides an antistatic flexible FPC circuit board to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides an antistatic flexible FPC circuit board, such as Figure 1-4 As shown, the flexible circuit board includes a flexible circuit board body 1, on which a circuit board 12 is movably arranged, on which a plug board 11 is fixedly installed, on which a card slot 111 is symmetrically provided, on which a slot 2 adapted to the plug board 11 is fixedly installed, on which a button slot 21 is provided, in which a button 3 is slidably installed, in which a connecting block slot 22 is symmetrically provided, on which a button 3 is symmetrically provided with a connecting block slot 22. Corresponding to the inclined block 31, a connecting block 4 is slidably installed in the connecting block groove 22, a clamping block 41 passing through the slot 2 is fixedly installed on the connecting block 4, a first spring 42 is fixedly installed on one end of the connecting block 4 away from the clamping block 41, and the other end of the spring is fixedly connected to the connecting block groove 22, an inclined portion 411 is provided at one end of the clamping block 41 away from the connecting block 4, an inclined surface adapted to the inclined block 31 is provided on the connecting block 4, and a second spring 24 corresponding to the plug board 11 is provided in the slot 2.

[0025] When in use, align the plug board 11 with the slot 2 and push the plug board 11 in the direction of the slot 2. At this time, the inclined portion 411 on the card block 41 contacts the plug board 11. When the plug board 11 is pushed, the thrust is transmitted to the connecting block 4 through the inclined surface. The connecting block 4 compresses the first spring 42 to move to both sides, and the card block 41 can automatically give way to the connecting block groove 22. When the plug board 11 is inserted into the preset position, the card slot 111 corresponds to the position of the card block 41. At this time, under the elastic action of the first spring 42, the card block 41 is inserted into the card slot 111, and the plug board 11 is fixed and limited, so that the plug-in of the flexible circuit board body 1 is realized. When leaving the flexible circuit board body 1, press the button 3 set on the slot 2. When the button 3 slides downward, the inclined surface on the connecting block 4 is squeezed by the inclined block 31 inserted into the connecting block groove 22. The connecting block 4 compresses the first spring 42, and the card block 41 leaves the card slot 111. Under the action of the second spring 24, the plug board 11 pops out of the slot 2 to achieve the effect of automatic separation. When the connecting block 4 is reset, it squeezes the inclined block 31 at the same time, driving the button 3 to reset. By setting the above mechanism, it can be connected without extra operation during installation. When separating, you only need to press the button 3 set on the surface of the slot 2, and the plug board 11 and the slot 2 can be automatically separated.

[0026] Furthermore, the plug board 11 is symmetrically hinged with a protection frame 113 on both sides, a torsion spring 114 is installed between the protection frame 113 and the plug board 11, and the plug board 11 is symmetrically provided with a limit plate 112 corresponding to the protection frame 113; when the plug board 11 is inserted, the protection frame 113 hinged on both sides of the plug board 11 can be pushed outward to rotate 90 degrees to be perpendicular to the plug board 11, at this time, the hand-held area of ​​the operator when connecting the flexible circuit board body 1 can be increased, and the operation is more convenient. When not in use, the protection frame 113 is in the torsion spring 114 The protective frame 113 is "U"-shaped and can frame both sides of the flexible circuit board body 1 after being reset. The limit plate 112 is used to prevent the protective frame 113 from excessively squeezing both sides of the flexible circuit board body 1. Since the flexible circuit board body 1 is usually very thin and light, it is not convenient to directly pinch its two sides, and it is easy to cause stress concentration of bending at the connection, causing damage to the flexible circuit board body 1. By setting the protective frame 113, it can facilitate manual operation and provide good protection for the connection of the flexible circuit board body 1.

[0027] Furthermore, a limiting edge 23 is symmetrically arranged at one end of the slot 2 away from the circuit board 12, and a fixing plate 32 adapted to the limiting edge 23 is fixedly mounted on the button 3; the button 3 is reset and limited by the limiting edge 23 to prevent the button 3 from escaping from the button slot 21, thereby enhancing the effective coordination of various components of the system.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
