[0031] The embodiment of the present application provides an engine cable assembly with a fancy braided sheath, as shown below. Figure 1-5 Provide a detailed description.

[0032] Reference Figure 1 The engine cable assembly with a fancy braided sheath of this embodiment includes a cable 3, a tail accessory 1, and a tail processing structure 2 connected to the tail accessory 1. The wire bundles 2-5 of the cable 3 are inserted into the tail accessory 1 and fixed by the tail processing structure 2. Specifically, the tail processing structure 2 is located at the outer ring of the connection between the wire bundles 2-5 and the tail accessory 1, and the tail processing structure 2 is configured as a transition arc from the tail accessory 1 to the wire bundles 2-5. The cable 3 includes branch cables with multiple functions, and the shielding sheaths of the branch cables with different functions are configured with different fancy textures, which can distinguish the branches of the engine cable that transmit different types of signals to realize different functions, thereby improving the functional differentiation of the branches.

[0033] Reference Figure 4-5 , by adjusting the arrangement structure of the spindle bobbin 4-1 of the shielding braiding machine, the fancy braiding effect can be achieved. Different arrangements can weave shielding sheaths with different fancy textures, such as Figure 5 The shield braiding machine spindle distribution structure 4 shown in the figure shows a two-color wire spindle distribution diagram, where the black circle represents one color and the white circle represents another color. Figure 4 The braided cable 3 has a two-color sheath and an integrated braided structure.

[0034] Furthermore, the tail processing structure 2 includes a pressure plate and a screw 2-1, and the wire bundle 2-5 located at the interface of the tail accessory 1 is fixed by the cooperation of the pressure plate and the screw 2-1; the tail processing structure 2 also includes an insulating self-adhesive tape 2-2 wrapped around the outside of the screw 2-1, and the insulating self-adhesive tape 2-2 is wrapped from the tail accessory 1 to the wire bundle 2-5 in a transition arc shape from thick to thin. Since there is a protrusion on the structure of the screw 2-1, by wrapping the insulating self-adhesive tape 2-2, the protrusion of 2-1 can be prevented from damaging other structures, thereby providing effective protection.

[0035] To further enhance shielding, the tail processing structure 2 also includes a braided end cap structure, located on the outer layer of the insulating self-adhesive tape 2-2. This double-layer braided end cap structure is integrally woven with the outer shielding sheath of the cable 3. In this embodiment, the tail accessory 1 achieves a 360-degree connection between the outer shielding sheath of the cable 3 and the shell of the tail accessory 1 through the shielded braided end cap. This significantly improves shielding continuity compared to conventional shielding connection methods that use a pressure plate filled with the base material.

[0036] Preferably, the braided end of the braided end structure is tied with the body winding wire of the shielding sheath to form a binding structure 2-4, which can improve the stability of the overall structure and the shielding continuity.

[0037] Considering engine weight, this embodiment reduces the weight of the entire engine cable assembly. First, a weight-reducing tail attachment 1 specifically designed for the engine is designed. Since the straight tail attachment's original wall thickness (0.75mm to 1.5mm) is small and its length is short, changing the wall thickness significantly reduces weight. Therefore, no structural weight reduction is required. Instead, the material used for the straight tail attachment is improved, replacing stainless steel with a titanium alloy. Titanium alloy boasts superior strength to stainless steel and meets the operational requirements of tail attachment 1. Regarding the curved tail attachment 1-1, since titanium alloy is difficult to machine, resulting in a long production cycle and high costs, while stainless steel is relatively easy to machine and has a shorter production cycle, the wire clamping housing of curved tail attachment 1-1 remains made of stainless steel. Based on the original tail attachment structure, the wall thickness of the curved tail attachment is reduced from 2.5mm to 1.5mm, achieving weight reduction. Simulation analysis has verified that the reduced-wall tail attachment meets operational strength requirements.

[0038] The embodiment provided by the present invention uses a shielded braiding machine to braid and cover the tail accessories on the outside of the tail accessories, and adopts a double-layer braiding process to improve the continuity of the shielding; by adjusting the arrangement structure of the spindle bobbins of the shielded braiding machine, a fancy braiding effect is achieved, and different arrangements can weave shielding sheaths with different fancy textures. A weight-reducing tail accessory specifically for the engine is also designed, in which the straight tail accessory is designed to be weight-reduced by changing the material from stainless steel to titanium alloy. The strength of titanium alloy is higher than that of stainless steel and can meet the use requirements of the tail accessories. The bent tail accessory reduces the weight of the tail accessory by reducing the wall thickness of the bent tail joint from 2.5mm to 1.5mm. The tail joint with reduced wall thickness has been verified by relevant simulation analysis and can meet the use strength requirements.

[0039] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
