Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and in particular to an insulating sleeve for automobiles. Background Technology

[0002] With the rapid development of the automotive industry, the electronic and electrical systems inside vehicles have become increasingly complex. As a key component of these systems, automotive wiring harnesses bear the crucial responsibility of transmitting power and signals. However, during actual vehicle operation, wiring harnesses often face challenges from various harsh environmental factors. For example, the temperature inside a car's engine compartment can reach over 100°C, and there is significant heat radiation, which can easily lead to aging of the wiring insulation and performance degradation. During vehicle operation, wiring harnesses are subjected to vibration, friction, and mechanical stress, potentially causing insulation wear and cracking. Furthermore, some chemical substances inside the vehicle, such as engine oil and coolant, can also corrode the wiring insulation. Therefore, it is often necessary to install insulating sleeves on the wiring harnesses for protection.

[0003] However, the existing automotive insulating sleeves on the market require professional tools and technicians for installation and maintenance. Not only is the installation process very complicated, but the maintenance cost is also high and the maintenance efficiency is low. Utility Model Content

[0004] To simplify the installation and maintenance process of automotive insulating sleeves, reduce reliance on specialized tools and technicians, thereby lowering maintenance costs and improving maintenance efficiency, while ensuring effective protection of automotive wiring, this application provides an automotive insulating sleeve.

[0005] This application provides an automotive insulating sleeve, which adopts the following technical solution: An automotive insulating sleeve includes a first half-sleeve and a second half-sleeve that are separately arranged. One side edge of the first half-sleeve and the second half-sleeve are rotatably connected together by a hinge. The other side edge of the first half-sleeve and the second half-sleeve is provided with a locking assembly for detachably locking the two. Semicircular grooves extending along their length are formed on the two opposing inner side walls of the first half-sleeve and the second half-sleeve. When the first half-sleeve and the second half-sleeve are closed, the two semicircular grooves enclose a cavity for receiving power supply lines.

[0006] By adopting the above technical solution, the sleeve is designed as a split structure, which can be opened and closed directly without the need to insert the wire from the end, greatly simplifying the installation and maintenance process; the hinge and locking components work together to ensure the sealing and firmness of the sleeve when closed, and can be quickly opened for wire placement or maintenance, which can be operated without professional tools and can be completed by ordinary personnel, reducing the reliance on professional technicians.

[0007] Optionally, the locking assembly includes: A snap fastener is provided on the first half-sleeve; A locking block is provided on the second half-sleeve, and a locking groove adapted to the buckle is provided on the locking block, and the buckle engages with the locking groove.

[0008] By adopting the above technical solution, the cooperation between the buckle and the slot can achieve quick locking and separation. The operation does not require tools and can be completed by ordinary personnel, reducing the reliance on professional technicians.

[0009] Optionally, the insulating sleeve is configured as a multi-segment structure along its length, and a connecting assembly is provided between two adjacent segments of the insulating sleeve. The two adjacent segments of the insulating sleeve are detachably connected by the connecting assembly. The connecting assembly includes two connecting protrusions, which are respectively located at the ends of one end of the first half-sleeve and the second half-sleeve. The other ends of the first half-sleeve and the second half-sleeve are provided with grooves, and the connecting protrusions are interference-fitted with the grooves.

[0010] By adopting the above technical solution, the insulating sleeve is set as a multi-segment structure, which allows for flexible splicing of the insulating sleeve according to the actual length of the wire, making it more applicable; the interference fit between the connecting protrusion and the groove ensures the connection stability between adjacent segments of the insulating sleeve, while also facilitating disassembly and adjustment.

[0011] Optionally, an elastic reset element is provided at the hinge joint of the first half-sleeve and the second half-sleeve. The elastic reset element is a torsion spring, and the two ends of the torsion spring are fixedly connected to the first half-sleeve and the second half-sleeve, respectively.

[0012] By adopting the above technical solution, the elastic force of the torsion spring can automatically spring the two halves of the sleeve apart when the locking component is released, without the need to manually pry them apart, further improving the convenience of operation, and is especially suitable for scenarios of one-handed operation or operation in confined spaces.

[0013] Optionally, both ends of the receiving cavity are provided with sealing elements, which are annular silicone rings, and the inner diameter of the silicone ring is adapted to the outer diameter of the wire.

[0014] By adopting the above technical solution, the silicone ring can fill the gap between the wire and the receiving cavity, effectively preventing dust, moisture and chemical liquids from entering, and enhancing the sealing and protection effect of the sleeve.

[0015] Optionally, multiple elastic protrusions are evenly distributed on the inner sidewall of the semicircular groove, and the elastic protrusions extend along the length of the semicircular groove and are made of nitrile rubber.

[0016] By adopting the above technical solution, the elasticity of nitrile rubber can adapt to wires of different diameters, while increasing the friction between the wire and the sheath, reducing wire swaying caused by vibration during vehicle operation, and avoiding wear.

[0017] Optionally, both the first half-sleeve and the second half-sleeve are made of high-temperature resistant silicone.

[0018] By adopting the above technical solutions, high-temperature resistant silicone can resist the high temperature and heat radiation in the engine compartment, delay the aging of the sleeve, and ensure the insulation and protection performance during long-term use.

[0019] Optionally, a wear-resistant layer is provided on the outer wall of both the first half-sleeve and the second half-sleeve.

[0020] By adopting the above technical solution, the wear-resistant layer can enhance the anti-friction ability of the sleeve surface, reduce wear when in contact with other automotive parts, and extend service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By designing the sleeve as a split structure, it can be opened and closed directly without having to thread the wire through the end, greatly simplifying the installation and maintenance process; the hinge and locking components work together to ensure the sealing and firmness of the sleeve when closed, and can be quickly opened for wire placement or maintenance. No special tools are required for operation, and ordinary personnel can complete the task, reducing the reliance on professional technicians. 2. The combination of buckles and slots enables quick locking and unlocking. No tools are required for operation, and ordinary personnel can complete the task, reducing reliance on professional technicians. 3. By adding a wear-resistant layer, the anti-friction ability of the sleeve surface can be enhanced, reducing wear when in contact with other automotive parts and extending service life.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0025] This application discloses an insulating sleeve for automobiles.

[0026] Reference Figure 1 The automotive insulating sleeve includes a first half-sleeve 11 and a second half-sleeve 12, both of which are elongated semi-tubular structures. The first half-sleeve 11 and the second half-sleeve 12 are made of high-temperature resistant silicone (temperature range -40℃ to 200℃), and both outer walls are coated with a 0.3mm thick polytetrafluoroethylene wear-resistant layer 13.

[0027] Reference Figure 1 The first half-sleeve 11 and the second half-sleeve 12 are connected on one side by a hinge 14. The hinge 14 includes a bushing fixed to the edge of the first half-sleeve 11 and a rotating shaft fixed to the edge of the second half-sleeve 12. The rotating shaft passes through the bushing to achieve rotation. An elastic return member 15, which is a torsion spring, is sleeved on the outside of the hinge 14. The two ends of the torsion spring are fixedly connected to the first half-sleeve 11 and the second half-sleeve 12, respectively. In its natural state, the torsion spring can keep the two half-sleeves open at an angle (approximately 30°).

[0028] Reference Figure 1 and Figure 2 The first half-sleeve 11 and the second half-sleeve 12 have locking components 2 on their other edges for detachably locking the two. Locking components 2 include a snap-fit ​​21 and a locking block 22. The snap-fit ​​21 is integrally formed on the outer wall of the first half-sleeve 11 and is an L-shaped snap-fit ​​made of an elastic metal sheet. A locking block 22 is integrally formed on the corresponding position on the outer wall of the second half-sleeve 12. The locking block 22 has a rectangular groove 23 that matches the end of the snap-fit ​​21. When the snap-fit ​​21 engages with the groove 23, the two half-sleeves are tightly closed.

[0029] Reference Figure 1 and Figure 2 The first half-sleeve 11 and the second half-sleeve 12 each have a semi-circular groove 16 on their opposing inner sidewalls. When the two semi-circular grooves 16 are closed, they form a receiving cavity with a diameter suitable for common automotive wires, such as 2-8mm. Multiple nitrile rubber elastic protrusions 17 (semi-circular cross-section, 0.8mm high, evenly distributed along the length, spaced 5mm apart) are fixed to the inner sidewalls of the semi-circular grooves 16 through a vulcanization process. Annular grooves are formed at both ends of the receiving cavity, and sealing elements 18, which are silicone rings, are embedded within these grooves. The inner diameter of the silicone ring is the same as the diameter of the receiving cavity.

[0030] Reference Figure 1 and Figure 2The insulating sleeve is designed as a multi-segment unit (each segment 10-30cm long) along its length. A connecting component 3 is provided between adjacent segments of the insulating sleeve, allowing for detachable connection between adjacent segments. The connecting component 3 includes connecting protrusions 31. Two connecting protrusions 31 are provided. The two connecting protrusions 31 are integrally formed at the ends of the first half-sleeve 11 and the second half-sleeve 12 of the first segment sleeve, respectively. Annular grooves 32 are formed at the corresponding ends of the first half-sleeve 11 and the second half-sleeve 12 of the second segment sleeve. The connecting protrusions 31 and the grooves 32 are press-fitted, thereby achieving detachable fixing of the two segments of the sleeve.

[0031] The working principle of this application embodiment is as follows: During installation, press the buckle 21 to disengage it from the slot 23. Under the action of the torsion spring, the first half-sleeve 11 and the second half-sleeve 12 will automatically open. Place the wire into the semi-circular groove 16, close the two half-sleeves, and engage the buckle 21 with the slot 23. If the length needs to be adjusted, the multiple sleeve sections can be spliced ​​with the groove 32 via the connecting protrusion 31. The elastic protrusion 17 presses the wire to prevent shaking, the seal 18 blocks external impurities, and the high-temperature resistant material and wear-resistant layer 13 ensure long-term performance. During maintenance, simply open the buckle 21 to remove the wire. The operation is convenient.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
