[0022] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0023] This embodiment relates to a fixing structure applicable to an FPC, including a separator plate 1 and an FPC 2. The FPC 2 is a flexible structure, which is well-known to those skilled in the art. A mushroom head 3 is provided on the separator plate 1, and an FPC limiting structure 6 adapted to the mushroom head 3 is provided on the FPC 2. The FPC limiting structure 6 includes a positioning hole 7, and a plurality of outwardly divergent positioning tracks 8 are provided outside the positioning hole 7. An anti-tearing hole 9 is provided at the end of the free end of each positioning track 8 extending outward.
[0024] Preferably, the FPC 2 is positioned and connected to the separator plate 1 through the cooperation of the FPC limiting structure 6 and the mushroom head 3. During the production process, through the positioning and pressing connection by the operator, the FPC limiting structure 6 is aligned with the mushroom head 3, and force is applied to press the FPC 2 so that the FPC limiting structure 6 deforms and sleights over the mushroom head 3, and then the FPC 2 is made to fit with the separator plate 1.
[0025] The mushroom head 3 includes an integral upper umbrella head 4 and a lower umbrella head 5; the maximum diameter of the upper umbrella head 4 is greater than the maximum diameter of the lower umbrella head 5, and the lower umbrella head 5 is connected to the upper surface of the separator plate 1.
[0026] Correspondingly, the maximum diameter of the positioning hole 7 is consistent with the maximum diameter of the lower umbrella head 5. Therefore, when the FPC limiting structure 6 deforms and passes through the upper umbrella head 4 under the force applied by the operator, it can be stably connected to the lower umbrella head 5 and will not become loose.
[0027] Each extension line of each positioning channel 8 extending into the positioning hole 7 coincides with the diameter of the positioning hole 7. In this embodiment, as Figure 3 shown, the number of positioning channels 8 is preferably four, and the included angle formed by any two of the positioning channels 8 extending is 90°. It should be noted that in this embodiment, the positioning channel 8 is specifically a groove or a channel without limitation, and it is used for deformation and connection of the positioning hole 7 and the anti-tearing hole 9; in addition, it can be understood that the positioning hole 7 and the positioning channel 8 are jointly used to absorb tolerances to ensure the accurate installation of the component.
[0028] A deformation part 10 is formed between any two adjacent positioning channels 8. When an operator applies force to press and deform the FPC limiting structure 6, the deformation part 10 deforms so that the upper umbrella head 4 can pass through the positioning hole 7.
[0029] The positioning channel 8 and the anti-tearing hole 9 are formed in a communicating manner. The anti-tearing hole 9 is used to inhibit the outward transmission of deformation and prevent the FPC 2 from being torn under the action of excessive deformation force, thereby improving the stability and reliability of the structure.
[0030] Preferably, both the positioning hole 7 and the anti-tearing hole 9 are through holes.
[0031] Thus, the fixing structure applicable to the FPC disclosed by the present utility model has the following advantages compared with the prior art:
[0032] (1) Reduce the input cost of hot riveting equipment, and there is no need to purchase new equipment for hot riveting processing;
[0033] (2) Solve the problem of arching after the PFC is bent, and it also helps to achieve automated mass production;
[0034] (3) Reduce the input cost of the back glue material.
[0035] The above embodiments are not limitations on the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present utility model also fall within the protection scope of the present utility model.
