Technical Field

[0001] This utility model relates to the field of wire harness technology, and in particular to a wrapping mechanism for wire harnesses and a wire harness. Background Technology

[0002] During the use of wire harnesses, wrapping mechanisms are typically used to protect, secure, and insulate them. However, existing wrapping mechanisms, due to the characteristics of the wrapping materials, are prone to generating significant stress at the wrapping point, leading to material damage and compromising the protective effect on the wire harness. This stress concentration problem is particularly pronounced when the wrapping material is an elastic material such as sponge, easily causing material fatigue, tearing, or adhesive layer failure.

[0006] In one embodiment, when the package is in an unfolded state, the two sides of the package are respectively a first overlapping area and a second overlapping area, and the middle area is a base bonding area, and the cut is located in the base bonding area; when the package is wrapped around the outer periphery of the wire harness body, the first overlapping area is bonded to the second overlapping area, and the base bonding area is bonded to the outer periphery of the wire harness body.

[0008] In one embodiment, the cut is arranged in a strip shape, and its length direction is parallel to the axial direction of the wire harness body.

[0009] In one embodiment, the package includes a protective layer and an adhesive layer disposed inside the protective layer, the adhesive layer being used to adhere to the outer periphery of the wire harness body.

[0015] The advantages of this utility model's wrapping mechanism and wire harness compared to existing technologies are as follows: By setting several slits in the wrapping component and making the distribution direction of the slits parallel to the axis of the wire harness body, the stress generated during the wrapping process is effectively reduced, significantly lowering the probability of the wrapping component breaking due to stress concentration and significantly improving the service life of the wrapping component; at the same time, the wrapping component can better fit the wire harness body, enhancing the protection effect on the wire harness body and ensuring stable protection of the wire harness during use.

[0032] See Figures 1 to 5 As shown, in a first aspect, this utility model provides a wrapping mechanism for a wire harness, comprising: a wrapping component 1, the wrapping component 1 having a plurality of slits 2, the plurality of slits 2 being linearly distributed and having a gap between adjacent slits 2; when the wrapping component 1 wraps around the wire harness body 3 along the outer periphery of the wire harness body 3, the distribution direction of the slits 2 is parallel to the axial direction of the wire harness body 3.

[0033] Specifically, the packaging mechanism of this embodiment provides several linearly distributed and spaced slits 2 on the packaging component 1, and the distribution direction of the slits 2 is parallel to the axial direction of the wire harness body 3. The slits 2 break the continuity of the packaging component 1. When the packaging component 1 bends around the wire harness body 3, the slits 2 can produce slight deformation, thereby dispersing the stress generated during the packaging process to each slit 2 area and avoiding stress concentration in one place that could damage the packaging component 1.

[0034] In actual operation, the operator wraps the package 1 around the wire harness body 3. Since the distribution direction of the cuts 2 is consistent with the axial direction of the wire harness body 3, as the package 1 gradually fits the wire harness, the cuts 2 will open or close at a certain angle as the package 1 bends. These tiny deformations continuously adjust the stress distribution inside the package 1, so that the package 1 can wrap more smoothly around the outer periphery of the wire harness.

[0035] This structural design effectively reduces the stress generated during the wrapping process, significantly lowering the probability of damage to the wrapping component 1 due to stress concentration, and substantially improving its service life. Simultaneously, the wrapping component 1 better conforms to the wire harness, enhancing its protective effect and ensuring stable protection during use.

[0036] In one specific embodiment, when the package 1 is in the unfolded state, the two sides of the package 1 are the first overlapping area 1a and the second overlapping area 1b, respectively, and the middle area is the base bonding area 1c, and the cut 2 is provided in the base bonding area 1c; when the package 1 is wrapped around the outer periphery of the wire harness body 3, the first overlapping area 1a is bonded to the second overlapping area 1b, and the base bonding area 1c is bonded to the outer periphery of the wire harness body 3.

[0037] Specifically, the package 1, in its unfolded state, is divided into a first overlapping area 1a, a second overlapping area 1b, and a base bonding area 1c, clearly defining the function of each area. The base bonding area 1c is used to directly bond with the wire harness body 3 to tightly wrap the wire harness body 3; the first overlapping area 1a and the second overlapping area 1b on both sides cooperate to achieve fixation and sealing during wrapping. The cut 2 is placed in the base bonding area 1c because the base bonding area 1c is in direct contact with the wire harness, and the stress generated during wrapping is concentrated in this area. By setting the cut 2 in the base bonding area 1c, the stress can be dispersed, avoiding failure of the bonding between the base bonding area 1c and the wire harness due to excessive stress.

[0038] In addition, this application provides two packaging structures: folded packaging and rolled packaging, to meet different usage needs.

[0039] Fold-over-wrap structure: The base bonding area 1c is folded around the wire harness and covers the outer periphery of the wire harness body 3. The inner side of the first overlapping area 1a is bonded to the inner side of the second overlapping area 1b, and neither the first overlapping area 1a nor the second overlapping area 1b contacts the wire harness body 3. This structural design achieves wrapping and fixation without increasing the number of wrapping layers around the wire harness. When wrapping the wire harness body 3 using this structure, the operator first aligns the base bonding area 1c with the wire harness body 3, ensuring it adheres tightly to the wire harness surface. Next, the base bonding area 1c is folded in half along the middle, and the inner side of the first overlapping area 1a is bonded to the inner side of the second overlapping area 1b. Ultimately, the outer periphery of the wire harness body 3 is wrapped only by the base bonding area 1c, while the first overlapping area 1a and the second overlapping area 1b only serve a fixing function and do not contact the wire harness body 3.

[0040] The wrapping structure consists of the inner side of the second overlapping area 1b and the inner side of the base bonding area 1c, which are bonded to the outer periphery of the wire harness body 3. The inner side of the first overlapping area 1a is bonded to the outer side of the second overlapping area 1b. The cuts 2 can be linearly distributed longitudinally at any position in the base bonding area 1c to accommodate stress conditions at different locations during the wrapping process. When wrapping the wire harness body 3 using this structure, the second overlapping area 1b and the base bonding area 1c are sequentially wrapped and bonded to the outer periphery of the wire harness body 3, so that they jointly wrap the wire harness. Finally, the first overlapping area 1a is bonded to the outer side of the second overlapping area 1b, completing the wrapping process.

[0041] These two wrapping structure designs allow the wrapping mechanism to be adapted to different needs. The folded wrapping structure reduces the number of wrapping layers and lowers material costs; the coiled wrapping structure increases the number of wrapping layers, improving sealing and strength. The slits 2 are flexibly distributed to adapt to complex wire harness shapes, enhancing wrapping stability. At the same time, the slits 2 are located in the base bonding area 1c, effectively dispersing wrapping stress and improving wrapping reliability and wire harness protection.

[0042] In one specific embodiment, the cut 2 is located at the middle position of the substrate bonding area 1c.

[0043] Specifically, the cut 2 is positioned in the middle of the base bonding area 1c, allowing for flexible adaptation to both folded and rolled wrapping structures. In the folded wrapping structure, the cut 2 is located diagonally opposite the junction of the first overlapping area 1a and the second overlapping area 1b, i.e., at the fold. This arrangement ensures that when the package 1 is folded, a symmetrical stress structure is formed around the cut 2 as the center line. When the package 1 bends and deforms, the cut 2 acts as a stress dispersion equilibrium point, promoting uniform deformation on both sides of the package 1 and efficiently distributing stress throughout the entire package 1, avoiding wrinkles and damage caused by stress concentration on one side. In the rolled wrapping structure, the cut 2, located in the middle of the base bonding area 1c, acts as a stress dispersion "hub," working in conjunction with the base bonding area 1c and the overlapping area structure to evenly diffuse stress to all parts of the base bonding area 1c, preventing excessive local stress. Compared to structures where the cut 2 is at the edge of the base bonding area 1c, the cut 2, located in the middle, ensures the package 1 remains flat when folded and better handles complex stresses when rolled.

[0044] In the folded packaging structure, taking the packaging of the wiring harness body 3 inside a car dashboard as an example, the operator aligns the base bonding area 1c with the wiring harness body 3 and then folds it in half. Since the cut 2 is located at the diagonal position where the first overlapping area 1a and the second overlapping area 1b connect, i.e., at the fold, the two sides of the package 1 deform synchronously under stress. Even if the wiring harness body 3 has a certain curvature, the package 1 can still fit tightly, and the surface is flat and wrinkle-free. When winding and wrapping complex wiring harnesses for industrial robots, the base bonding area 1c is first bonded to the wiring harness body 3. As the package 1 is gradually wound, the cut 2 in the middle guides the package 1 to deform evenly, effectively dispersing the complex stress generated by the bending and turning of the wiring harness body 3, ensuring that the package 1 fits firmly against the wiring harness body 3, and is not prone to loosening or damage even after long-term use.

[0045] The design of the slit 2 position enables the packaging mechanism to exhibit superior performance in both packaging structures. When folded, it significantly improves the flatness and aesthetics of the package, meeting the appearance requirements of demanding scenarios such as electronic devices. When rolled, it enhances the adaptability of the package component 1 to the complex shape of the wire harness body 3, improving packaging stability and reliability, making it suitable for protecting the wire harness body 3 in complex environments such as industrial machinery. At the same time, the uniform stress distribution greatly reduces material fatigue of the package component 1, effectively reducing subsequent maintenance and replacement costs, providing a high-quality solution for the packaging of the wire harness body 3 that combines efficiency, stability, and economy.

[0046] It is understood that in other embodiments, the cut 2 may also be provided at any other location in the substrate bonding area 1c to adapt to different stress distributions.

[0047] In one specific embodiment, the cut 2 is arranged in a strip shape, and its length direction is parallel to the axial direction of the wire harness body 3.

[0048] Specifically, the strip-shaped slit 2 provides a clear guiding path, ensuring that the stress of the wrapping layer is evenly distributed along the entire length of the slit 2 edge during bending, avoiding extreme stress concentration. The length direction of the slit 2 is parallel to the axis of the wire harness body 3, ensuring that bending occurs at points requiring deformation, such as bends or forks in the wire harness body 3. This fully utilizes the length of the slit 2 to disperse stress, forming an efficient stress-relieving structure that effectively addresses stress issues during folding and wrapping processes.

[0049] In the folded wrapping structure, the strip-shaped cut 2 located in the middle of the base bonding area 1c serves as a folding line. When the wrapping 1 is folded, it guides the wrapping 1 to bend and forms a symmetrical stress structure with itself as the center, causing the wrapping 1 to deform evenly on both sides and efficiently distributing the stress to the entire wrapping 1, avoiding wrinkles and damage caused by stress concentration on one side. In the winding wrapping structure, the strip-shaped cut 2 can undergo circumferential stretching or compression deformation according to the stress conditions at different positions of the wire harness body 3, flexibly adapting to the complex stress distribution during the winding process, ensuring that the wrapping 1 fits tightly against the wire harness body 3.

[0050] By designing the slit 2 as a strip, the stress dispersion capability of the wrapping component 1 is significantly improved under both wrapping structures, effectively addressing wrapping situations with high stress. Through circumferential deformation, the problem of localized stress concentration caused by bending in the wrapping component 1 is alleviated, reducing material fatigue and the risk of damage. Simultaneously, its regular shape facilitates processing and manufacturing, reducing production difficulty and cost, and improving production efficiency. While ensuring the wrapping effect, this enhances the practicality and economy of this invention.

[0051] More specifically, the length of the incision 2 ranges from 4 to 5 mm, the width ranges from 0.8 to 2.2 mm, and the interval between the incisions 2 is 5 to 8 mm. The length of the slit 2 is set to 4-5mm. This range can effectively guide the release of pressure in the stress concentration area when the protective layer 11 is bent, avoiding insufficient stress dispersion due to excessive length, and also preventing excessive length from weakening the overall structural strength of the protective layer 11, thus maintaining the material's load-bearing capacity. The width is controlled between 0.8-2.2mm, which not only meets the extension space requirements when the material is deformed, avoiding excessive narrowness that would cause the slit 2 to close or restrict deformation, but also maintains the tightness of the wrapping through an appropriate width, preventing excessive width from causing the protective layer 11 to loosen or the wire harness body 3 to shake. The interval length of the slit 2 is 5-8mm, which can balance the stress dispersion effect, avoiding the risk of sudden drop in local strength or material tearing due to excessively short intervals. At the same time, the reasonable spacing ensures that an effective stress transmission path is formed between adjacent slits 2, improving the overall stability of the protective layer 11 in bending, stretching and other scenarios, so that the protective layer 11 can achieve an optimized balance between stress release and structural strength while adapting to the specifications of the wire harness body 3.

[0052] It is understood that in other embodiments, the length range, width range, and interval length of the cut 2 can be set to other values ​​as needed to adapt to the size changes of the wire harness body 3.

[0053] In one specific embodiment, the package 1 includes a protective layer 11 and an adhesive layer 12 disposed inside the protective layer 11, the adhesive layer 12 being used to adhere to the outer periphery of the wire harness body 3.

[0054] Specifically, the package 1 adopts a double-layer structure design with a protective layer 11 and an adhesive layer 12. The protective layer 11 is located on the outside and can resist the influence of external physical impacts, friction, and environmental factors on the wire harness body 3, providing a physical protective barrier for the wire harness body 3. The adhesive layer 12 is located on the inside of the protective layer 11 and achieves a firm connection between the package 1 and the wire harness body 3 through its own adhesiveness, ensuring that the package 1 is stably wrapped on the wire harness body 3. Whether folded or rolled, this double-layer structure can play its corresponding role and ensure the wrapping effect.

[0055] In use, align the adhesive layer 12 of the package 1 with the wire harness body 3, and gently press the package 1 to ensure full contact between the adhesive layer 12 and the surface of the wire harness body 3. The adhesive layer 12's stickiness will tightly adhere the package 1 to the outer periphery of the wire harness body 3. After wrapping, the protective layer 11 continues to function, blocking various external damaging factors and protecting the wire harness body 3. During folding and wrapping, the adhesive layer 12 ensures the connection between the package 1 and the wire harness body 3, while the protective layer 11 provides continuous protection.

[0056] This double-layer structure design not only ensures the strong connection between the package 1 and the wire harness body 3, making the package 1 less likely to fall off, but also effectively enhances the protection capability of the wire harness body 3 through the setting of the protective layer 11, extends the service life of the wire harness body 3, meets the protection needs of the wire harness body 3 in different usage scenarios, and is suitable for two types of packaging structures.

[0057] In one specific embodiment, the cut 2 is provided on the protective layer 11.

[0058] Cut 2 is placed in the protective layer 11. Utilizing the deformability of the protective layer 11, it allows the layer to better bend and deform according to the shape of the wire harness body 3 during the wrapping process. The deformation of the protective layer 11 causes the entire wrapping component 1 to adapt to the contour of the wire harness body 3. Simultaneously, since cut 2 does not involve the adhesive layer 12, the adhesion of the adhesive layer 12 is ensured to remain unaffected, guaranteeing the connection stability between the wrapping component 1 and the wire harness body 3. In both wrapping structures, this design achieves a balance between stress dispersion and stable connection.

[0059] When wrapping the wire harness body 3, the cut 2 on the protective layer 11 deforms as the wrapping component 1 bends, causing a slight displacement of the material in the protective layer 11 at the cut 2. This allows the protective layer 11 to tightly adhere to the irregular surface of the wire harness body 3. Meanwhile, the adhesive layer 12 maintains good adhesion, firmly fixing the wrapping component 1 to the wire harness body 3, achieving stable wrapping. Whether folding or rolling, the deformation of the protective layer 11 and the adhesiveness of the adhesive layer 12 work synergistically.

[0060] This slit 2 design scheme ensures the stress dispersion effect of the package 1 while maintaining the stability of the connection between the package 1 and the wire harness body 3, ensuring that the package 1 will not fail due to connection problems in the process of protecting the wire harness body 3, thus improving the overall performance of the package mechanism under the two package structures.

[0061] In one specific embodiment, the depth of the cut 2 is consistent with the thickness of the protective layer 11.

[0062] Specifically, the depth of the slit 2 is made consistent with the thickness of the protective layer 11. This maximizes the stress-dispersing effect of the slit 2 while ensuring the structural strength of the protective layer 11. When the protective layer 11 deforms under stress during the wrapping process, the slit 2, with a depth equal to the thickness of the protective layer 11, can fully participate in the deformation process, effectively dispersing the stress while preventing the strength of the protective layer 11 from being weakened due to an excessively deep slit 2. This depth design ensures the performance of the protective layer 11 during both folding and rolling wrapping processes.

[0063] During the wrapping process, when the protective layer 11 is subjected to stress generated by the wrapped wire harness body 3, the material at the cut 2 moves along with the deformation of the protective layer 11. Since the depth of the cut 2 is consistent with the thickness of the protective layer 11, the cut 2 can fully absorb and disperse the stress, allowing the protective layer 11 to deform uniformly while maintaining sufficient strength to resist external physical forces. Regardless of the wrapping structure, a balance between stress dispersion and the strength of the protective layer 11 can be achieved.

[0064] This slit depth design ensures that the protective layer 11 has sufficient strength to cope with the influence of the external environment, while achieving the best stress dispersion effect. This makes the package 1 effectively protect the wire harness body 3 while maintaining its own structural stability and reliability, thus extending the service life of the package 1 under both packaging structures.

[0065] In one specific embodiment, a release paper layer 4 is detachably connected to the inner side of the adhesive layer 12.

[0066] Specifically, a removable release paper layer 4 is provided inside the adhesive layer 12. Utilizing its low adhesion to the adhesive layer 12, the release paper layer 4 isolates the adhesive layer 12 when the package 1 is not in use, preventing the release paper from contacting external objects, thereby effectively protecting the adhesiveness of the adhesive layer 12 and ensuring that it can perform its fixing function normally when in use.

[0067] When using package 1, the operator first carefully peels off the release paper layer 4 from the inside of the adhesive layer 12 to expose the surface of the adhesive layer 12, and then attaches the adhesive layer 12 of package 1 to the wire harness body 3 according to the method of folding or rolling the package, and completes the wrapping operation by the adhesiveness of the adhesive layer 12.

[0068] The release paper layer 4 effectively protects the adhesiveness of the adhesive layer 12, avoiding the failure of the package 1 due to accidental adhesion of the adhesive layer 12, improving the convenience and reliability of the package 1 in both packaging structures, and making the packaging operation more convenient and efficient.

[0069] In one specific embodiment, the protective layer 11 is a sponge.

[0070] Specifically, sponge is chosen as the material for the protective layer 11. Based on the sponge's excellent elasticity and cushioning properties, when the wire harness body 3 is subjected to external impact, the sponge can absorb the impact energy through its own compression and rebound, reducing the impact of the impact force on the wire harness body 3. At the same time, the sponge's flexibility allows it to easily adapt to various shapes of the wire harness body 3, facilitating the bending and fitting of the wrapping component 1. The sponge protective layer 11 demonstrates its unique advantages during both folding and rolling wrapping processes.

[0071] When wrapping the wire harness body 3, the sponge protective layer 11 is adhered to the surface of the wire harness body 3. The sponge can tightly fill the uneven parts of the surface of the wire harness body 3, forming a good wrapping effect. When the wire harness body 3 is subjected to external impacts, compression, etc., the sponge protective layer 11 absorbs the impact energy and protects the internal structure of the wire harness body 3 from damage. Regardless of the wrapping structure, the sponge protective layer 11 can provide good cushioning and fit.

[0072] The sponge protective layer 11 significantly improves the protective performance of the wire harness body 3, effectively coping with various external impacts and vibrations, and ensuring the normal operation of the wire harness body 3 in complex environments. At the same time, due to the softness of the sponge, the wrapping process is smoother, reducing the difficulty of wrapping operations for both wrapping structures.

[0073] It is understood that in other embodiments, the protective layer 11 may also be made of materials such as rubber, polyurethane, polyvinyl chloride (PVC), silicone rubber, and metal braided mesh, all of which can adapt to the design of setting slits 2 on the protective layer 11. Rubber has good elasticity, and slits 2 can effectively disperse stress, with coordinated deformation at slits 2 when bent; polyurethane has high strength, and slits 2 can guide deformation and avoid stress concentration that could damage the material; PVC has good processability, and slits 2 facilitate its deformation in a predetermined direction during wrapping; silicone rubber has strong temperature resistance, and slits 2 allow it to release stress through deformation even at high and low temperatures; metal braided mesh has high hardness, and a properly designed slit 2 allows it to deform appropriately at the bends of the wire harness body 3 while maintaining structural strength and shielding performance. After setting slits 2, these materials can all work together with the overall structure to disperse stress during folding and wrapping, adapt to the shape changes of the wire harness body 3, and ensure the protective effect of the wire harness body 3.

[0074] Secondly, this utility model embodiment also provides a wire harness, including a wire harness body 3, the outer periphery of which is covered with the wrapping mechanism for the wire harness as described above.

[0075] The aforementioned wrapping mechanism, featuring multiple innovative structures and functions, is applied to the wire harness body 3. Through its unique design, the wrapping mechanism provides comprehensive protection and performance enhancement for the wire harness. The stress dispersion design, zoned wrapping design, and multi-layered structure design of the wrapping mechanism work synergistically, combining two wrapping structures to meet the needs of the wire harness in different application scenarios.

[0076] During the production of the wire harness, a suitable wrapping mechanism is selected based on the specifications, shape, and usage environment of the wire harness body 3. It is determined whether to use a folded wrapping or a winding wrapping structure to tightly wrap the wrapping mechanism around the outer periphery of the wire harness body 3, thus completing the wire harness manufacturing process.

[0077] By applying the wrapping mechanism and selecting two wrapping structures, the stress resistance of the wire harness is effectively improved, making it less prone to damage during bending, stretching, and other operations; the sealing and robustness of the wire harness are enhanced, preventing external factors from corroding the wire harness; the protective performance of the wire harness is improved, the service life of the wire harness is extended, production costs are reduced, and the market competitiveness of the wire harness product in different application scenarios is improved.

[0078] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
