[0005] To achieve the above objectives, this utility model provides the following technical solution: a touch film FPC connection structure, including a fixing frame, a limiting plate, a wiring sleeve, a connecting block, and a second bottom pad;

[0006] A bearing mechanism is provided above the fixing frame. The bearing mechanism includes a limiting plate, a limiting post, a cover plate, and a limiting cover. The fixing frame and the limiting cover are used to clamp and fix the whole.

[0008] The bottom pad is provided with a wiring mechanism on its side. The wiring mechanism includes a wiring sleeve, a connecting block, a conductive wire, a first conductor, and a second conductor. The wiring sleeve and the connecting block are used for quick connection and fixation.

[0009] As a preferred technical solution of this utility model, a limiting column is fixedly connected above the fixed frame in the bearing mechanism. The limiting column has a trapezoidal structure, and a limiting plate is fixedly connected at the center line of the side of the limiting column. An arc-shaped protrusion is provided on the inner side of the limiting plate, and a row of arc-shaped grooves is evenly opened on the lower left side of the fixed frame.

[0010] By adopting the above technical solution, the device can use the trapezoidal limiting column as a fixing component to apply pressure and guide and position the internal components, preventing the internal components from shifting.

[0011] As a preferred technical solution of this utility model, a cover plate is clamped above the fixing frame, and a circular hole is opened at the splice between the cover plate and the fixing frame to allow the first wire and the second wire to pass through;

[0012] Using the above technical solution, the device fixes the first and second wires by clamping them with a cover plate and a fixing frame. The modular structure can improve the convenience of equipment replacement. At the same time, the clamping can prevent the wire harness from shaking and ensure stability.

They can effectively isolate the wires and prevent short circuits, and can also buffer external impacts to a certain extent, protecting the wires and connection structures, while facilitating disassembly and maintenance.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 8The present invention provides a touch film FPC connection structure, comprising a fixing frame 1, a limiting plate 2, a wiring sleeve 3, a connecting block 4, a limiting post 5, a cover plate 6, a limiting cover 7, a conductive wire 8, a limiting groove 9, a first connecting plate 10, a second connecting plate 11, a first bottom pad 12, a first wire 13, a second wire 14, and a second bottom pad 15.

[0032] In the load-bearing mechanism set above the fixed frame 1, the trapezoidal limiting post 5 plays a key role. The limiting post 5 is fixed above the fixed frame 1, and the inner limiting plate 2 with an arc-shaped protrusion is connected to the center line of the side. At the same time, a row of arc-shaped grooves are evenly distributed on the lower left side of the fixed frame 1. With this design, the limiting post 5 can not only serve as a fixing component to apply pressure to the internal parts, but also play a precise guiding and positioning role, effectively preventing the internal parts from shifting during operation and ensuring the stability and reliability of the entire connection structure.

[0033] The isolation mechanism below the limiting cover 7 consists of a first connecting plate 10, a second connecting plate 11, a first bottom pad 12, and a second bottom pad 15. The first connecting plate 10 and the second connecting plate 11 are responsible for isolating and fixing the wires, ensuring electrical separation between the wires, and improving the safety of the equipment. The cover plate 6 clamped above the fixing frame 1 has a circular hole at its splice with the fixing frame 1 for the first wire 13 and the second wire 14 to pass through. This clamping method adopts a modular structure, which not only facilitates the replacement of equipment parts, but also effectively prevents wire harness vibration and further ensures the stability of the connection.

[0034] The wiring mechanism on the side of the first base pad 12 includes a wiring sleeve 3, a connecting block 4, a conductive wire 8, a first conductor 13, and a second conductor 14. The wiring sleeve 3 and the connecting block 4 are used for quick docking and fixing. In the isolation mechanism, the second connecting plate 11, the first base pad 12, the first connecting plate 10, and the second base pad 15 are arranged in sequence. Limiting grooves 9 are opened on their sides. These limiting grooves 9 fit with the limiting posts 5, which further improves the safety of the equipment. The first conductor 13 and the second conductor 14 are sandwiched between the isolation mechanisms. The connecting block 4 is fitted on its left side, and the wiring sleeve 3 is fitted on the left side of the connecting block 4. The trapezoidal springs on both sides of the wiring sleeve 3 can quickly engage and fix with the connecting block 4. Furthermore, by increasing the conductive contact area between the wiring sleeve 3 and the connecting block 4, the safety and durability of the equipment are improved.

[0035] Working principle: When using a touch film FPC connection structure, firstly, the first wire 13 and the second wire 14 are placed in the limiting grooves 9 of the first connecting plate 10 and the second connecting plate 11 respectively. The limiting grooves 9 are used to initially position the wires. Next, the connecting block 4 is fitted on the left side of the first wire 13 and the second wire 14. Then, the wiring sleeve 3 is fitted on the connecting block 4. At this time, the trapezoidal springs on both sides of the wiring sleeve 3 will tightly lock the connecting block 4, achieving a quick and stable connection. The conductive wire 8 on the left side of the wiring sleeve 3 is used to connect with external devices. Then, the isolation mechanism with the wires and wiring mechanism set is placed on the fixing frame 1. The first wire 13 and the second wire 14 pass through the circular hole at the splice between the cover plate 6 and the fixing frame 1. Finally, the cover plate 6 is placed on the fixing frame 1, and the limiting cover 7 is placed on top of the cover plate 6. The entire connection structure is fixed by the clamping of the fixing frame 1 and the limiting cover 7.

[0036] During use, external signals are transmitted to the wiring sleeve 3 via the conductive wire 8, and then to the first wire 13 and the second wire 14 via the connecting block 4, so as to realize stable signal transmission between the touch film and other devices. When maintenance or replacement of parts is required, the internal wires and connecting parts can be easily inspected, repaired or replaced simply by opening the limit cover 7.

[0037] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
