Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire harness sheaths, and more specifically to a waterproof wire harness sheath with an anti-bending structure. Background Art
[0002] In modern industry and electronics, wire harnesses are important components for connecting and managing wires to ensure the effective transmission of power and signals. With the development of technology, the number of electronic devices is increasing, and the demand for wire harnesses is also growing accordingly, especially in the fields of automobiles, aerospace, ships, industrial automation and communication equipment. In these applications, wire harnesses are often exposed to harsh environments, such as moisture, dust, chemicals, high and low temperatures, etc. Therefore, it is very important to protect wire harnesses from these environmental factors.
[0003] Traditional wire harness sheaths are usually made of plastic or rubber, and their main function is to protect wires from physical damage and chemical corrosion. However, existing wire harness sheaths often have problems with poor protective effect and anti-bending performance.
[0004] After searching, a Chinese patent with announcement number CN220821151U discloses a waterproof wire harness sheath with an anti-bending structure, which adopts an anti-bending mechanism and a connecting ring between the anti-bending structures. The anti-bending mechanism is made of PP plastic. The elastic wings of the anti-bending mechanism have high toughness, which reduces the impact force of the waterproof wire harness caused by bending due to impact. The connecting ring connects the three anti-bending mechanisms and will not separate from the waterproof wire harness body when it is impacted.
[0005] However, when the structure is actually used, the anti-bending mechanism in the structure is difficult to fully protect the waterproof wire harness. It only performs anti-bending treatment on a local position of the waterproof wire harness, while the unprotected part will still bend, and the pressure resistance effect is not good. In view of this, the utility model proposes a waterproof wire harness sheath with an anti-bending structure. Utility Model Content
[0006] In order to overcome the above defects of the prior art, the utility model provides a waterproof wire harness sheath with a bending resistance structure to solve the problems raised in the above background technology.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof wiring harness sheath with an anti-bending structure, comprising a waterproof wiring harness body, a plurality of anti-pressure rings are arranged on the outside of the waterproof wiring harness body, a bellows is arranged between every two anti-pressure rings, and the bellows sleeve is arranged on the outside of the waterproof wiring harness body, the two ends of the bellows are respectively connected to the corresponding anti-pressure rings, and the outer diameters of the bellows and the anti-pressure rings are matched with the outer diameter structure of the waterproof wiring harness body.
[0008] It can be seen that in the above structure, multiple compression rings and bellows made of polypropylene material form a sheath structure, which is installed on the outside of the waterproof wiring harness body, which can not only provide good protection for the waterproof wiring harness body, but also improve the compression resistance of the waterproof wiring harness body.
[0009] In order to improve the anti-bending effect of the waterproof wiring harness body and improve the service life of the waterproof wiring harness body, preferably, an anti-bending component is arranged between every two anti-compression rings, the number of the anti-bending components is set to multiple, and the multiple anti-bending components are distributed in a ring shape on the outer wall of the anti-compression ring, the anti-bending component includes an anti-bending bar, the anti-bending bar is arranged between two anti-compression rings, the surface of the anti-compression ring is provided with a mounting sleeve, both ends of the anti-bending bar are provided with bearings, one end of the bearing is provided with a rotating block, one end of the rotating block is provided with a mounting column, the anti-bending bar and the anti-compression ring are both made of polypropylene material, the rotating block is rotatably connected to one end of the anti-bending bar through the bearing, the surface of the rotating block is provided with anti-slip grooves, the inner wall of the mounting sleeve is provided with an internal thread groove, the outer surface of the mounting column is provided with an external thread groove, the mounting column and the mounting sleeve are threadedly connected through the internal thread groove and the external thread groove.
[0010] Technical effects and advantages of the utility model:
[0011] 1. By setting the anti-bending component, the anti-compression strip made of polypropylene material is installed between every two anti-compression rings, so that the waterproof harness body has a good buffering effect when it is bent, thereby ensuring the strength of the waterproof harness body and avoiding the bending of the waterproof harness body. In addition, multiple anti-bending components are distributed in a ring shape on the outside of the waterproof harness body, so that the waterproof harness body can alleviate the bending force no matter from which direction it is subjected to the bending force, thereby improving the service life of the waterproof harness body;
[0012] 2. A sheath structure is formed by installing multiple anti-pressure rings on the outside of the waterproof wire harness body and installing a corrugated tube between the multiple anti-pressure rings. The anti-pressure rings in the structure are made of polypropylene material, which can have a good buffering effect on the waterproof wire harness body, and the corrugated tube between the two anti-pressure rings can have a good protective effect on the outer surface of the waterproof wire harness body. The corrugated tube can be retracted and expanded, thereby facilitating the protection of waterproof wire harness bodies of different lengths and improving the protection range.
