In new energy vehicles, the positive wiring harness is responsible for connecting the positive terminal of the battery and load devices such as motors and controllers.

[0003] However, the waterproof protection effect of conventional positive wiring harnesses is poor. If the wiring harness is exposed to a humid environment, it is easy to cause problems such as circuit short circuit or leakage. In addition, the interface of the wiring harness may not be well sealed, causing moisture or liquid to penetrate into the wiring harness, thereby affecting the normal use of the wiring harness.

[0004] Therefore, the utility model provides a positive wiring harness with waterproof protection to solve the problems raised in the above background technology. Utility Model Content

[0010] Furthermore, the first layer is made of polytetrafluoroethylene, and the second layer is made of cross-linked polyolefin;

[0011] Through the above technical solution, the first layer uses polytetrafluoroethylene, which can effectively prevent moisture penetration and ensure that the positive wiring harness can maintain stable performance even in a humid environment. The second layer uses cross-linked polyolefin, which not only enhances the mechanical strength of the wiring harness, but also improves its insulation performance.

[0012] Furthermore, the third layer is made of fluoroplastics, and the fourth layer is made of polyvinyl chloride;

[0013] Through the above technical solution, the third layer is made of fluoroplastics, which has excellent high temperature resistance and good chemical stability. The fourth layer is made of polyvinyl chloride, which has good insulation performance and certain mechanical strength.

[0014] Furthermore, terminals are fixedly provided at both ends of the wiring harness body, and heat shrink sleeves are fixedly provided at the lower ends of the two outer ends of the terminals;

[0016] Furthermore, the two terminals are fixedly arranged at the inner end of the protective shell, and the terminal is fixedly arranged at the rear end of the movable door;

[0017] Through the above technical solution, fixing the terminal inside the protective shell can provide additional protection to prevent the terminal from being damaged or disturbed by the external environment. Since the terminal is fixed at the rear end of the movable door, the probability of the terminal being hit by external objects can also be reduced, increasing the overall stability of the device. The terminal is fixed at the rear end of the movable door, so that when it is necessary to connect or disconnect an external device, the user only needs to open the movable door to easily access the terminal. This design simplifies the operation process, improves work efficiency, and also reduces the risk of damaging the terminal due to improper operation.

[0018] Furthermore, the two protective shells are movably arranged on the upper end of the heat shrinkable sleeve, and the outer end of the terminal is coated with a waterproof coating;

[0019] Through the above technical solution, the heat shrink tubing itself has good insulation and protection performance, which can protect the internal wires or cables from the influence of the external environment. The setting of the protective shell further enhances this protection effect, providing an additional protective barrier for the terminal and the entire connection system. The outer end of the terminal is coated with a waterproof coating. This design significantly improves the waterproof performance of the terminal. In a humid or rainy environment, the waterproof coating can effectively prevent moisture from penetrating into the interior of the terminal, thereby avoiding problems such as short circuit or corrosion caused by moisture.

[0033] By clamping the wire harness ferrule 4 on the outer end of the wire harness body 1 and placing the terminal 3 into the inner end of the protective shell 10 and then closing the movable door 8, the wire harness and the terminal 3 are effectively protected from interference and damage from the external environment, thereby extending the service life of the wire harness and the terminal 3.

[0034] The wiring harness body 1 includes a first layer 11, a second layer 12 is fixedly arranged at the inner end of the first layer 11, a third layer 13 is fixedly arranged at the inner end of the second layer 12, and a fourth layer 14 is fixedly arranged at the inner end of the third layer 13. By setting a multi-layer structure, the wires inside the positive wiring harness can be effectively protected and its service life and safety performance can be improved. The first layer 11 is made of polytetrafluoroethylene, and the second layer 12 is made of cross-linked polyolefin. The first layer 11 is made of polytetrafluoroethylene, which can effectively prevent moisture penetration and ensure that the positive wiring harness can maintain stable performance in a humid environment. The second layer 12 is made of cross-linked polyolefin, which not only enhances the mechanical strength of the wiring harness, but also improves its insulation performance. The third layer 13 is made of fluoroplastics, and the fourth layer 14 is made of polyvinyl chloride. The third layer 13 is made of fluoroplastics, which has excellent high temperature resistance and good chemical stability. The fourth layer 14 is made of polyvinyl chloride, which has good insulation performance and certain mechanical strength.

[0035] The multi-layer structure can enhance the wear resistance of the wiring harness body 1, and the outer layer provides surface protection, making the wiring harness more durable in long-term use. The multi-layer structure design can effectively extend the service life of the positive wiring harness, and the layer-by-layer protection and enhanced wear resistance can reduce the wear and aging speed of the wiring harness, so that it can maintain a good condition for a longer time.

[0036] Terminals 3 are fixedly provided at both ends of the wiring harness body 1, and heat shrink sleeves 2 are fixedly provided at the lower ends of the two outer ends of the terminals 3. The heat shrink sleeves 2 can be tightly wrapped around the two ends of the wiring harness body 1, effectively preventing moisture and other external liquids from penetrating into the wiring harness, and ensuring the electrical performance and safety of the wiring harness. The terminals 3 can firmly connect the wiring harness to electrical equipment or other wiring harnesses to ensure that the current can be smoothly transmitted and realize the circuit function. The two terminals 3 are fixedly provided at the inner end of the protective shell 10, and the terminals 3 are fixedly provided at the rear end of the movable door 8. The fixed terminals 3 at the inner end of the protective shell 10 can provide additional protection to prevent the terminals 3 from being damaged or disturbed by the external environment.

Two protective shells 10 are movably arranged on the upper end of the heat shrinkable tube 2, and the outer end of the terminal 3 is coated with a waterproof coating 15. The heat shrinkable tube 2 itself has good insulation and protection properties, and can protect the internal wires or cables from the influence of the external environment. The setting of the protective shell 10 further enhances this protection effect and provides an additional protective barrier for the terminal 3 and the entire connection system. The outer end of the terminal 3 is coated with a waterproof coating 15. This design significantly improves the waterproof performance of the terminal 3. In a humid or rainy environment, the waterproof coating 15 can effectively prevent moisture from penetrating into the terminal 3, thereby avoiding problems such as short circuit or corrosion caused by moisture.

[0037] The wiring harness body 1 and the terminal 3 are safely placed inside the protective shell 10 and the wiring harness ferrule 4, reducing the risk of external collision and friction and improving the safety of the equipment. When the wiring harness or the terminal 3 needs to be maintained or replaced, through this operation step, the movable door 8 and the wiring harness ferrule 4 can be opened more conveniently for maintenance and replacement operations, thereby improving the maintenance convenience of the equipment.

[0038] Working principle: push the connecting rod 6 backward, then clamp the wiring harness sleeve 4 on the outer end of the wiring harness body 1, then open the movable door 8, put the terminal 3 into the inner end of the protective shell 10, close the movable door 8, and then push the connecting rod 6 in the opposite direction to clamp the wiring harness body 1 inside the wiring harness sleeve 4.
