Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and specifically to a fixing device for a flattened signal transmission carrier. Background Technology

[0002] Flattened signal transmission solutions are generally used in space-constrained areas requiring flat cross-sections. Taking FFC / FPC as an example, FFC / FPC solutions are currently commonly used in consumer electronics or packaging applications, typically fixed to plastic parts using adhesives or heat-sealing methods. However, applying such flattened solutions to low-voltage automotive applications presents certain challenges. Due to the limitations of the automotive environment, adhesive bonding may be affected by the placement area and the high temperatures of the application environment. If conventional adhesive methods are used, the adhesive's adhesion will deteriorate due to high temperatures, causing the FFC / FPC to detach and the fixation to fail.

[0003] Current cable ties are generally used in areas such as wire harnesses and conduits. The interface after they are tightened is generally circular, which is mutually exclusive with the design goal of flattening. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a fixing device for a flattened signal transmission carrier. A flattened U-shaped groove serves as the fixing cross-section for flat cables such as FFC / FPC, and a snap-fit ​​structure is provided on the U-shaped groove for fixation. The specific technical solution is as follows: A fixing device for a flat signal transmission carrier includes a cable tie fixing head, which is a flat surface for supporting an FFC / FPC. An integrally formed hinge fixing structure is provided on the flat surface of the cable tie fixing head. One side of the hinge fixing structure extends out as a pressure plate, and the pressure plate has a seam with local thinning. A sponge is provided on the inner side of the pressure plate. The other side extends out a barb structure, which engages with the pressure plate to hook the pressure plate and fix the FFC / FPC.

[0005] Furthermore, the sponge is fixed to the pressure plate by adhesive.

[0006] Furthermore, an inclined surface is provided on the outermost side of the pressure plate and the barb.

[0007] Furthermore, the cable tie fixing head is constructed from an arrow-shaped head and a flexible flange.

[0008] In use, after the FFC / FPC is inserted into the U-shaped groove, the pressure plate is bent. Due to the hinge structure, the pressure plate can be bent at the joint. The beveled surfaces on the pressure plate and the hooks cause the hooks to open outwards when the pressure plate is pressed in, allowing the pressure plate to embed into the hooks. The sponge, due to its compressibility, can compress the FFC / FPC tightly without damaging it. The size and compression rate of the sponge can be set according to the requirements of the fixed target.

[0009] This invention uses a hinge structure and sponge assistance to fix flat wires such as FFC / FPC without compromising their flatness; it also minimizes damage to the flat wires caused by the fixing components; and effectively avoids the risk of adhesive falling off due to heat and the damage to the structure and flatness of the flat wires caused by traditional cable ties.

[0012] 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.

[0013] like Figure 1-2 As shown, a fixing device for a flat signal transmission carrier includes a cable tie fixing head 4, which is a flat surface facing upwards to support an FFC / FPC. An integrally formed hinge fixing structure is provided on the flat surface facing upwards of the cable tie fixing head. A long strip structure extends from one side of the hinge fixing structure as a pressure plate. The pressure plate has a slit 2 for local thinning. A sponge 1 is provided on the inner side of the pressure plate. A barb 3 extends from the other side, which engages with the pressure plate to hook the pressure plate and fix the FFC / FPC.

[0014] Furthermore, the sponge is fixed to the pressure plate by adhesive.

[0015] Furthermore, an inclined surface is provided on the outermost side of the pressure plate and the barb.

[0016] Furthermore, the cable tie fixing head is constructed from an arrow-shaped head and a flexible flange.

[0017] In use, after the FFC / FPC is inserted into the U-shaped groove, the pressure plate is bent. Due to the hinge structure, the pressure plate can be bent at the joint. The beveled surfaces on the pressure plate and the hooks cause the hooks to open outwards when the pressure plate is pressed in, allowing the pressure plate to embed into the hooks. The sponge, due to its compressibility, can compress the FFC / FPC tightly without damaging it. The size and compression rate of the sponge can be set according to the requirements of the fixed target.
