It is made of high-strength and high-wear-resistant materials. The wear-resistant layer 1 is fixedly connected to the inside of the heat-insulating layer 2. The heat-insulating layer 2 is located inside the wear-resistant layer 1 and is an important component of the protective sleeve. It is mainly composed of high-efficiency heat-insulating materials, such as ceramic fibers and aerogels. Ceramic fibers have the characteristics of high temperature resistance and low thermal conductivity, which can effectively block external heat from being transferred to the wiring harness and protect the wiring harness from being damaged in high temperature environments. The heat-insulating layer 2 is fixedly connected to the inside of the heat-insulating layer 2. The buffer layer 3 is located inside the heat-insulating layer 2 and undertakes the important task of absorbing vibrations and impacts. It is usually made of soft and elastic materials, such as sponges and foams. These materials have good buffering properties and can effectively absorb vibrations and impacts generated during vehicle driving, reducing the impact on the wiring harness.
[0035] Reference Figures 3 to 5 The interior of the buffer layer 3 is fixedly connected with a sealing component for protecting subsequent workpieces. The sealing component includes a fixed sleeve 6, the outside of the fixed sleeve 6 is fixedly connected to the inside of the buffer layer 3, the fixed sleeve 6 can be fixed to the inside of the buffer layer 3, the inside right side of the fixed sleeve 6 is fixedly connected with multiple springs 7, and the inside of the fixed sleeve 6 can fix multiple springs 7, the other end of the multiple springs 7 is fixedly connected with a limiting ring 8, which can be pushed by the spring 7, and the outside of the limiting ring 8 is slidably connected to the inside of the fixed sleeve 6, and the fixed sleeve 6 can limit the movement of the limiting ring 8. The left side of the limiting ring 8 is fixedly connected with an extension ring 9, and when the limiting ring 8 is driven, the extension ring 9 can be pushed. The outer right end of the extension ring 9 is slidably connected to the inside of the fixed sleeve 6, and the extension ring 9 can be restricted by the fixed sleeve 6. The left side of the extension ring 9 is fixedly connected with a sealing gasket 10, and the sealing gasket 10 can be moved when the extension ring 9 moves;
[0036] Reference Figure 6 and Figure 7The outside of the wear-resistant layer 1 is fixedly connected with a connecting plate 12, and the front and rear ends of the left side of the connecting plate 12 are fixedly connected with a bayonet 20. The left side of the connecting plate 12 is fixedly connected with a fixing plate 13. The bayonet 20 can be fixed by the connecting plate 12, and the bayonet 20 is inserted into the interior of the fixing plate 13 to achieve the fixing effect. The front and rear ends of the interior of the fixing plate 13 are fixedly connected with a positioning shell 15, and the positioning shell 15 can be fixed by the fixing plate 13, and then it can carry subsequent workpieces. The interior of the positioning shell 15 is slidably connected with a metal cup 21, the metal cup 21 can slide inside the positioning shell 15, and two steel balls 19 are slidably connected to the right side of the metal cup 21. The front and rear sides of the bayonet 20 are in contact with the adjacent ends of the two steel balls 19. The bayonet 20 can push the two steel balls 19 to move inside the metal cup 21. The front and rear ends of the right side of the metal cup 21 are both provided with limiting grooves 16. The outer portion of the steel ball 19 is engaged with the inner portion of the limiting groove 16, and then the steel ball 19 can be engaged with the inner portion of the limiting groove 16, so that the connecting plate 12 and the fixing plate 13 are connected to each other.
[0037] The front and rear ends of the right side of the interior of the fixing plate 13 are fixedly connected to spring 2 17, and the right side of the spring 2 17 is fixedly connected to a metal block 18. The outside of the metal block 18 is slidably connected to the inside of the metal cup 21, and the outside of the bayonet 20 is slidably connected to the inside of the metal block 18. The interior of the fixing plate 13 is fixedly connected to the docking joint 14, and the interior of the docking joint 14 is fixedly connected to the chuck 4. The interior of the chuck 4 is slidably connected to multiple cables 5. The interior of the docking joint 14 is fixedly connected to a retaining ring 11, and the right side of the retaining ring 11 contacts the left side of the sealing gasket 10. First, the staff needs to take a strong magnet, which can be used to suck the metal cup 21 and the metal block 18 so that the metal block 18 can squeeze the spring 2 17 to shrink, so that the steel ball 19 can be loosened. At this time, by pulling out the connecting plate 12, the bayonet 20 and the steel ball 19 can be separated from each other when the connecting plate 12 is pulled out. This design can achieve the effect of quick installation and quick disassembly.
[0038] Working principle: When the operator needs to install and dock the fixing plate 13 of the connecting plate 12, first, the latch 20 fixed at one end of the connecting plate 12 is placed into the interior of the positioning shell 15. The latch 20 can squeeze the steel balls 19 on both sides to slide, so that the steel balls 19 can be engaged in the limiting grooves 16 opened by the metal cup 21, thereby achieving the positioning effect. The grooves opened between the latches 20 can limit the steel balls 19, and at the same time, the connecting plate 12 and the fixing plate 13 can not be separated from each other, and the wiring harness can be prevented from falling off, thereby preventing external The strong pulling makes the cable 5 have poor contact, resulting in irreversible consequences. When the connecting plate 12 and the fixing plate 13 need to be separated from each other, the staff first needs to take a strong magnet. The strong magnet can attract the metal cup 21 and the metal block 18, so that the metal block 18 can squeeze the spring 2 17 to shrink, so that the steel ball 19 can be loosened. At this time, by pulling out the connecting plate 12, the pin 20 and the steel ball 19 can be separated from each other when the connecting plate 12 is pulled out. Such a design can achieve the effect of quick installation and quick disassembly, avoiding prolonged disassembly time.
[0039] When the buffer layer 3 and the docking joint 14 need to be docked with each other, first, the spring 17 can be used to push the limiting ring 8 to move, and during the movement of the limiting ring 8, the extension ring 9 can be driven to move. When the extension ring 9 is pushed by the force exerted on the spring 17, the sealing gasket 10 can be blocked on one side of the retaining ring 11, and then the buffer layer 3 and the docking joint 14 can be sealed to prevent external dust and some fine substances from entering the interior of the buffer layer 3, thereby protecting the cable 5. At the same time, the chuck 4 can separate multiple cables 5 and prevent the cables 5 from overheating and causing a short circuit. The wear-resistant layer 1 and the heat-insulating layer 2 can provide good protection for the internal cables 5. The wear-resistant layer 1 enhances the durability of the overall protective sleeve. At the same time, the external heat-insulating layer 2 can isolate the heat of the car itself, thereby protecting the cables 5.
