[0020] 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.

[0021] This utility model provides an electronic wire harness protective sleeve, such as Figure 1-4 As shown, the electronic wire harness protective sleeve includes an outer wear-resistant sheath 1, a middle flame-retardant and heat-insulating layer 2 is attached to the inner wall of the outer wear-resistant sheath 1, an inner buffer bushing 3 is attached to the inner wall of the middle flame-retardant and heat-insulating layer 2, and port reinforcing rings 4 are provided at the left and right ends of the outer wear-resistant sheath 1 and the middle flame-retardant and heat-insulating layer 2. Multiple sets of axial tensile ribs 5 are fixedly installed between the two sets of port reinforcing rings 4.

[0022] In practical applications, the outer wear-resistant sheath 1 is preferably made of high-strength, wear-resistant engineering plastic material, which can withstand friction and scratches, resist aging, and maintain stable appearance and performance. The middle flame-retardant and heat-insulating layer 2 is made of special flame-retardant fiber material, which is treated with special processes to maintain structural stability at high temperatures, prevent heat conduction, suppress the spread of fire, and provide safety protection for electronic equipment. The inner buffer bushing 3 is made of highly elastic silicone material, which can conform to the shape of the wire harness and absorb and disperse the impact force when subjected to external impact, preventing wire breakage. The port reinforcing ring 4 is made of metal material, which is precision machined and has high strength and hardness, enhancing the structural stability of both ends of the protective sheath. The axial tensile rib 5 is made of high-strength fiber rope with a unique weaving structure, which makes its tensile performance excellent and prevents the protective sheath from breaking due to wire harness stretching or twisting.

[0023] The outer wear-resistant sheath 1, the middle flame-retardant and heat-insulating layer 2, and the inner buffer bushing 3 are all equipped with port sealing rings 6 at both ends. The cross-section of the opposite side of the two sets of port sealing rings 6 is U-shaped. The inner walls of the two sets of port sealing rings 6 are provided with lips. The two sets of port sealing rings 6 are fixedly connected to the two sets of port reinforcing rings 4 by buckles.

[0024] During actual installation, the U-shaped cross-section design of the port sealing ring 6 can fit tightly against the wire harness port, forming a double sealing effect. The lip structure of its inner wall further enhances the sealing performance, effectively preventing moisture and dust from entering the protective sleeve composed of the outer wear-resistant sheath 1, the middle flame-retardant heat insulation layer 2, and the inner buffer bushing 3. The snap-fit ​​connection method ensures a stable connection between the sealing ring and the port reinforcing ring 4, avoiding sealing failure caused by vibration or impact.

[0025] The inner buffer bushing 3 is provided with multiple sets of built-in wire harness positioning buckles 7. The multiple sets of built-in wire harness positioning buckles 7 are integrally injection molded with the inner buffer bushing 3, and the claw tips of the multiple sets of built-in wire harness positioning buckles 7 are rounded.

[0026] The built-in wire harness positioning buckle 7 not only achieves precise positioning of the wire harness, preventing it from sliding or tangling inside the protective sleeve, but also avoids damage to the wire harness during installation or use due to the rounded corners of its claws, ensuring the integrity of the wire harness and the stability of signal transmission. At the same time, the one-piece injection molding process ensures a firm connection between the built-in wire harness positioning buckle 7 and the inner buffer bushing 3, improving the reliability of the overall structure.

[0027] The outer wear-resistant sheath 1 is provided with multiple sets of external fixing clamps 9. The lower side of each set of external fixing clamps 9 is C-shaped, and the lower opening of each set of external fixing clamps 9 is provided with a buckle.

[0028] The C-shaped design of the external fixing clamp 9 allows it to fix the protective sleeve, which consists of the outer wear-resistant sheath 1, the middle flame-retardant heat insulation layer 2, and the inner buffer bushing 3, onto the equipment housing or bracket, preventing the protective sleeve from shaking with the vibration of the wiring harness. It is suitable for fixing scenarios such as car bodies and industrial equipment racks.

[0029] Multiple sets of adjustable straps 1 are fixedly installed on the lower side of the outer wear-resistant sheath 1, and the upper ends of the multiple sets of adjustable straps 1 are fixed to the outer wall of the outer wear-resistant sheath 1 by injection molding.

[0030] The adjustable cable tie 1 is made of elastic nylon material, which can help fix the protective sleeve composed of the outer wear-resistant sheath 1, the middle flame-retardant heat insulation layer 2 and the inner buffer bushing 3. It can be tied to other wire harnesses or pipes to reduce independent fixing points and is suitable for scenarios with limited space where external fixing clamps 9 cannot be installed.

[0031] The inner wall of the inner buffer bushing 3 is provided with multiple sets of intermediate sealing sections 8. The inner walls of the multiple sets of intermediate sealing sections 8 are all annular protrusions. The multiple sets of intermediate sealing sections 8 are integrally formed with the inner buffer bushing 3.

[0032] The annular protrusion structure of the intermediate sealing section 8 can fit tightly against the surface of the wire harness, forming multiple sealing barriers to effectively prevent moisture, dust and other impurities from seeping into the protective sleeve along the axial direction of the wire harness. Its integral molding process with the inner buffer bushing 3 ensures the stability and durability of the sealing structure, avoiding sealing failure caused by vibration or thermal expansion and contraction. At the same time, it also enhances the overall strength of the inner buffer bushing 3 and improves the protection effect on the wire harness.

[0033] The upper outer wall of the outer wear-resistant sheath 1 is provided with an identification groove 11, in which a label can be embedded, and a transparent protective cover is provided at the opening of the identification groove 11.

[0034] The design of the labeling slot 11 facilitates the classification and management of wire harnesses. Users can embed labels of different colors or contents in the labeling slot 11 according to actual needs to quickly identify information such as the purpose, specifications or connected equipment of the wire harness. The transparent protective cover effectively prevents the labels from being worn, contaminated or falling off, ensuring that the labeling information is clear and readable, and improving the efficiency and accuracy of wire harness management.

[0035] The outer surface of the outer wear-resistant sheath 1 is provided with an anti-ultraviolet coating, which is composed of acrylic anti-UV coating material.

[0036] The UV-resistant coating effectively absorbs and reflects ultraviolet rays, preventing the outer wear-resistant sheath from aging, discoloration, or performance degradation due to long-term exposure to sunlight. This extends the lifespan of the protective sheath and maintains the stability of its appearance and performance, making it particularly suitable for protecting electronic device wiring harnesses in outdoor or direct sunlight environments.

[0037] An anti-rodent coating is provided between the outer wall of the outer wear-resistant sheath 1 and the anti-ultraviolet coating. The anti-rodent coating is composed of a polyolefin coating containing capsaicin.

[0038] The capsaicin component in the rodent-resistant coating releases a pungent odor and taste, effectively repelling rodents and preventing them from biting the outer wear-resistant sheath 1, thus protecting the wiring harness from rodent damage and ensuring the safety and reliability of electronic device wiring harnesses. It is especially suitable for environments with frequent rodent activity, such as the wild and warehouses.

[0039] An electromagnetic shielding layer is provided between the middle flame-retardant and heat-insulating layer 2 and the inner buffer bushing 3. The electromagnetic shielding layer is made of tin-plated copper mesh.

[0040] The electromagnetic shielding layer can effectively shield external electromagnetic interference, prevent electromagnetic waves from affecting signal transmission within the wire harness, and ensure the normal operation of electronic equipment in complex electromagnetic environments. At the same time, the tin-plated copper mesh material has good conductivity and corrosion resistance, which can maintain the stability of the electromagnetic shielding effect over a long period of time, improving the anti-interference ability and reliability of the wire harness. It is especially suitable for the protection of wire harnesses of electronic equipment with high requirements for electromagnetic environment, such as communication equipment and medical equipment.

[0041] Working Principle: The electronic wire harness protective sleeve consists of an outer wear-resistant sheath 1, a middle flame-retardant and heat-insulating layer 2, and an inner buffer bushing 3. The outer wear-resistant sheath 1 is the first line of defense, with high strength and wear resistance, resisting external friction and scratches, and reducing the risk of wire harness failure. The middle flame-retardant and heat-insulating layer 2 is closely attached to the inner layer and is made of special flame-retardant fiber material. It is structurally stable at high temperatures, preventing heat conduction and suppressing fire. The inner buffer bushing 3 is made of elastic silicone material, which fits the wire harness and absorbs and disperses impact force when subjected to impact, ensuring stable signal transmission. The three layers work together to achieve all-round protection. The port reinforcing ring 4 and the axial tensile rib 5 work together to enhance the strength of the protective sleeve. The port reinforcing ring 4 is made of high-strength metal material, resisting stress and preventing the protective sleeve from breaking and falling off at both ends. The axial tensile rib 5 has a unique braiding... The design incorporates various features including: a weave to disperse axial tension and prevent damage to the protective sleeve; a port sealing ring 6 to enhance sealing performance; a U-shaped cross-section to fit the port; a lip structure to strengthen the seal; a snap-fit ​​connection to prevent seal failure; an internal wire harness positioning buckle 7 for precise wire harness positioning; rounded claw tips to prevent damage to the wire harness; an external fixing clamp 9 with a C-shaped design to secure the protective sleeve and improve stability; an adjustable cable tie 1 for flexible fixing and adaptation to confined spaces; a central sealing section 8 with an annular protrusion to fit the wire harness, preventing impurities from seeping in and enhancing inner layer strength; a labeling groove 11 for convenient wire harness classification and management, allowing for the embedding of labels for identification information; an anti-UV coating to prevent outer layer aging; an anti-rodent coating to repel rodents; and an electromagnetic shielding layer to enhance the wire harness's anti-interference capabilities and ensure the normal operation of electronic equipment in complex electromagnetic environments.
