Description

Technical Field

[0001] This utility model relates to the field of flexible display technology, and more specifically, to a line clip mechanism applied to flexible display screens. Background Technology

[0002] In daily life, wire clips are widely used in the electronics industry, primarily at the wire exit points of plastic casings. Their purpose is to prevent long-term pulling from causing the solder wires to detach from the PCB board or break. However, due to the unique characteristics of flexible LED displays—their thinness and generally using a drip-resin process without other plastic components for securing the wires—only the flexible circuit board and connecting wires are soldered together. The common method is to apply hot melt adhesive or other soft glue to the solder wires for protection, but this results in an unsightly appearance and is prone to detachment, failing to effectively secure the wires. Especially under external force, the connecting wires are more likely to detach from the flexible circuit board, causing malfunctions in the flexible LED display. Therefore, a wire clip mechanism for flexible displays is provided to solve these problems. Utility Model Content

The flexible circuit board 11 controls the flexible display screen body through the connecting wire 12. The control technology used by the flexible circuit board 11 to control the flexible display screen body is existing technology, so its specific control process will not be described in detail here, as long as it meets the requirements of this application. The wire clamping assembly 13 is fixedly installed on the flexible circuit board 11 and performs a wire clamping operation on the connecting wire 12, thereby effectively preventing the connecting wire 12 from detaching from the flexible circuit board 11.

[0027] Please see Figure 3 and Figure 4 As shown, in this embodiment, the flexible circuit board 11 is provided with a solder pad 111, one end of the connecting wire 12 is electrically soldered to the solder pad 111, and the other end is electrically connected to the flexible display body, thereby realizing the control operation of the flexible circuit board 11 on the flexible display body; the flexible circuit board 11 is also provided with a through hole 112, and the line card assembly 13 passes through the flexible circuit board 11 through the through hole 112, thereby fixing the line card assembly 13 on the flexible circuit board 11.

[0028] Please see Figures 1-4 As shown, in this embodiment, the cable clamp assembly 13 includes a chuck body 131, a cover plate 132, and a fastener 133. The chuck body 131 is disposed on one side of the flexible circuit board 11 and engages with the connecting wire 12, thereby effectively preventing the connecting wire 12 from detaching from the flexible circuit board 11. The cover plate 132 is disposed on the other side of the flexible circuit board 11 opposite to the chuck body 131, and it penetrates the flexible circuit board 11 through a through hole 112 to contact and connect with the chuck body 131. The fastener 133 penetrates the cover plate 132 and is fixedly connected to the chuck body 131, thereby fixing the chuck body 131 onto the flexible circuit board 11.

[0029] Please see Figure 3 and Figure 4As shown, in this embodiment, the chuck body 131 is a hollow cavity with a fixing hole 1311. The fixing hole 1311 has a first internal thread, and the fastener 133 passes through the cover plate 132 and is detachably threaded to the fixing hole 1311. The chuck body 131 has a first through hole 1312 and a second through hole 1313 on opposite sides. The connecting wire 12 passes through the first through hole 1312 and the second through hole 1313 in sequence, thereby passing through the chuck body 131. The second through hole 1313 can perform a wire clamping operation on the connecting wire 12. A clamping plate 1314 is also fixedly installed in the chuck body 131, and the clamping plate 1314 can also perform a wire clamping operation on the connecting wire 12. Specifically, a first slot 13131 is provided on the second through hole 1313.

The fixing post 1321 is a hollow cylindrical cavity with openings at both ends, and a second internal thread is provided on its inner wall. The fixing post 1321 passes through the flexible circuit board 11 through the through hole 112 and contacts and connects with the corresponding fixing hole 1311. The fastener 133 passes through the fixing post 1321 and is detachably threadedly connected to the fixing hole 1311. Specifically, the fastener 133 is a fastening screw.

[0031] It should be noted that the specific assembly process of the wire clamp mechanism 10 applied to the flexible display screen of this utility model is as follows: First, the connecting wire 12 is fixedly soldered to the pad 111 on the flexible circuit board 11. Then, the cover plate 132 passes through the flexible circuit board 11 through the through hole 112. Then, the chuck body 131 is snapped onto the connecting wire 12 and installed correspondingly to the cover plate 132. Then, the fastener 133 passes through the cover plate 132 and is fixedly connected to the chuck body 131, so that the chuck body 131 snaps onto and contacts the connecting wire 12, thus completing the assembly operation of the wire clamp mechanism 10, thereby effectively preventing the connecting wire 12 from detaching from the flexible circuit board 11.
