Description

Technical Field

[0001] This invention relates to the field of electronic wire harnesses, specifically a high-sealing, aging-resistant, and waterproof general-purpose electronic wire harness. Background Technology

[0002] With the rapid development of electronic technology, electronic wire harnesses, as key components for signal transmission and power connection, have been widely used in various electronic devices and the automotive industry. In the automotive industry, wire harnesses run through various parts such as the engine compartment, chassis, and door interiors, undertaking the signal transmission and power distribution tasks of the vehicle's electrical system. In the field of electronic devices, wire harnesses are widely used in communication equipment, home appliances, industrial control systems, and outdoor electronic equipment, and are indispensable connection components to ensure the normal operation of the equipment.

[0003] Currently, common general-purpose electronic wire harnesses on the market mainly consist of a wire harness body and terminals located at both ends of the wire harness body. The wire harness body is usually composed of conductor cores and an insulating sheath covering the conductor cores. The terminals are fixedly connected to both ends of the conductor cores and are used to connect with the plug-in connectors of external devices to achieve electrical connection. When using this type of wire harness, the terminals at both ends are inserted into the connector interfaces of the corresponding devices, and the sealing structure inside the connector interface is used to achieve waterproof sealing of the plug-in parts.

[0004] However, the existing structure has obvious defects: the wire harness end itself does not have independent sealing and waterproof characteristics, and its sealing relies entirely on the external connector. There is an assembly gap at the connection between the insulating sheath and the terminal, and moisture can easily seep into the interior along the gap or the surface of the wire core, leading to oxidation and corrosion of the core wire and a decrease in insulation performance. Especially in the car engine compartment or outdoor humid environment, the connector seal is prone to aging and failure after long-term use, and the wire harness end itself lacks sealing ability, so the waterproof reliability is completely dependent on the quality of the connector, which poses a significant safety hazard. Therefore, in order to address the above problems, a high-sealing, aging-resistant, and waterproof general-purpose electronic wire harness is proposed. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a high-sealing, aging-resistant, and waterproof universal electronic wire harness.

[0006] The technical solution adopted by this invention to solve its technical problem is: a high-sealing, aging-resistant, and waterproof universal electronic wire harness, comprising a protective sleeve body, a sealing component provided at the end of the protective sleeve body, a partition plate provided on the inner wall of the protective sleeve body, a wire core installed on the inner wall of the protective sleeve body, the sealing component comprising an end sleeve, the end sleeve being installed at the end of the protective sleeve body, a through hole being opened on the end side of the end sleeve, an extended sealing sleeve being fixedly connected to the end side of the end sleeve, the extended sealing sleeve communicating with the through hole, the wire core being inserted through and inserted into the inner wall of the extended sealing sleeve, a sealing ring being fixedly connected to the inner wall of the extended sealing sleeve, the inner wall of the sealing ring contacting the outer wall of the wire core, and the extended sealing sleeve being configured as a frustum shape.

[0007] Preferably, the protective sleeve body includes an outer protective layer, an anti-aging sheath layer, a waterproof sealing layer, an inner insulation layer, and a support and reinforcement layer. The outer protective layer wraps around the outer wall of the anti-aging sheath layer, the anti-aging sheath layer wraps around the outer wall of the waterproof sealing layer, the waterproof sealing layer wraps around the outer wall of the inner insulation layer, the inner insulation layer wraps around the outer wall of the support and reinforcement layer, and the support and reinforcement layer wraps around the outer wall of the partition plate.

[0008] Preferably, the partition plate divides the interior of the protective sleeve body into multiple cavities, the wire core is installed in the cavity, and a filler is provided around the wire core and inside the cavity.

[0009] Preferably, a plug ring is fixedly connected to the end of the protective sleeve body, and an annular groove is formed on the inner wall of the end sleeve, with the plug ring inserted into the inner wall of the annular groove.

[0010] Preferably, the sealing rings are provided in multiple sets, and the multiple sets of sealing rings are arranged at intervals along the axial direction of the extended sealing sleeve.

[0011] Preferably, the protective sleeve body and the insert ring are integrally formed, and the sealing component and the insert ring are fixedly connected by hot pressing.

[0012] Preferably, the outer protective layer is made of nylon fiber, the anti-aging sheath layer is made of cross-linked polyethylene sheath material, the outer surface of the anti-aging sheath layer is coated with an ultraviolet absorber, the waterproof sealing layer is made of heat-shrinkable waterproof sleeve, and the inner insulation layer is made of polyvinyl chloride insulation layer.

[0013] Preferably, the support and reinforcement layer is made of a flexible insulating material, and the inner wall of the support and reinforcement layer is provided with annular corrugations.

[0014] Preferably, the filler is a waterproof paste material.

[0015] The advantages of this invention are: I. This invention provides a sealing assembly consisting of an end sleeve, an extended sealing sleeve, and a sealing ring at the end of the wire harness. The inner wall of the sealing ring is tightly fitted to the outer wall of the wire core to form multiple radial seals. The extended sealing sleeve is shaped like a frustum and generates radial compression when it mates with an external mounting hole to form an interference fit. This enables the end of the wire harness to have independent sealing and waterproofing capabilities without relying on an external connector sealing structure, thus improving the sealing characteristics and waterproofing reliability of existing wire harness ends.

[0016] II. The present invention adopts a multi-layer composite structure consisting of a support and reinforcement layer, an inner insulation layer, a waterproof sealing layer, an anti-aging sheath layer, and an outer protective layer. The inner wall of the support and reinforcement layer is provided with annular corrugations to enhance the pressure resistance and buffering capacity. The waterproof sealing layer uses a heat-shrinkable waterproof sleeve to form a dense waterproof barrier. The anti-aging sheath layer is made of cross-linked polyethylene material and coated with an ultraviolet absorber to resist aging. The layers work together to form a complete protection system, reducing the risk of insufficient aging resistance of existing wire harnesses and easy aging and cracking under harsh environments, which leads to a shortened service life.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail. This application discloses a high-sealing, aging-resistant, and waterproof universal electronic wire harness: Reference Figure 1 - Figure 2 and Figure 4 A high-sealing, aging-resistant, and waterproof general-purpose electronic wire harness includes a protective sleeve body 1, a sealing component at the end of the protective sleeve body 1, a partition plate 4 on the inner wall of the protective sleeve body 1, and a wire core 3 installed on the inner wall of the protective sleeve body 1. The sealing component includes an end sleeve 2, which is installed at the end of the protective sleeve body 1. A through hole 24 is opened on the end side of the end sleeve 2, and an extended sealing sleeve 21 is fixedly connected to the end side of the end sleeve 2. The extended sealing sleeve 21 communicates with the through hole 24. The wire core 3 is inserted through and into the inner wall of the extended sealing sleeve 21. A sealing ring 23 is fixedly connected to the inner wall of the extended sealing sleeve 21, and the inner wall of the sealing ring 23 contacts the outer wall of the wire core 3. The extended sealing sleeve 21 is shaped like a frustum. During operation, during the assembly process, the wire core 3 is first passed through the through hole 24 on the end side of the end sleeve 2, and then introduced into the interior of the extended sealing sleeve 21 through the through hole 24, so that the wire core 3 is inserted through and into the inner wall of the extended sealing sleeve 21. During this process, the wire core 3 passes through the extended sealing sleeve 21 in sequence. The sealing ring 23 is fixed to the inner wall of the sleeve 21. The inner wall of the sealing ring 23 is tightly attached to the outer wall of the wire core 3, forming multiple radial sealing barriers. This effectively prevents external moisture from seeping into the protective sleeve body 1 along the surface of the wire core 3. The extended sealing sleeve 21 adopts a frustum-shaped design, with its outer diameter gradually decreasing from the end of the sleeve 2 outward. This structure facilitates the insertion of the sealing assembly as a whole into the wire sheath or through-wall hole of the external equipment. On the other hand, during the insertion process, the frustum-shaped conical surface can apply radial compressive force between the end sleeve 2 and the mounting hole, so that the outer wall of the extended sealing sleeve 21 and the inner wall of the mounting hole form an interference fit, further enhancing the sealing effect of the wire harness end. At the same time, the end sleeve 2 serves as the base of the sealing assembly. After it is fixedly connected to the end of the protective sleeve body 1, the entire sealing assembly is securely installed on the wire harness end, so that the wire harness end itself has independent sealing and waterproof capabilities, without relying entirely on the sealing structure of the external connector.

[0022] Reference Figure 1 , Figure 3 and Figure 5The protective sleeve body 1 includes an outer protective layer 11, an anti-aging sheath layer 12, a waterproof sealing layer 13, an inner insulation layer 14, and a support and reinforcement layer 15. The outer protective layer 11 wraps around the outer wall of the anti-aging sheath layer 12, the anti-aging sheath layer 12 wraps around the outer wall of the waterproof sealing layer 13, the waterproof sealing layer 13 wraps around the outer wall of the inner insulation layer 14, the inner insulation layer 14 wraps around the outer wall of the support and reinforcement layer 15, and the support and reinforcement layer 15 wraps around the outer wall of the partition plate 4. During operation, the protective sleeve body 1 uses a multi-layer composite structure to provide all-round protection for the wire core 3. The innermost support and reinforcement layer 15 directly wraps around the outer wall of the partition plate 4, providing structural support and reinforcement for each cavity and the internal wire core 3, preventing deformation and damage to the wire core 3 when the wire harness is subjected to external compression or bending. The inner insulation layer 14 wraps around the outside of the support and reinforcement layer 15. As a basic electrical insulation barrier, it ensures electrical isolation between the wire core 3 and the outside world. The waterproof sealing layer 13 tightly covers the outer surface of the inner insulation layer 14, forming a dense waterproof barrier that effectively prevents moisture from penetrating radially into the interior of the protective sleeve body 1. The anti-aging sheath layer 12 covers the outside of the waterproof sealing layer 13 and uses its excellent resistance to heat and oxygen aging and ultraviolet aging to resist the aging damage of the sheath layer caused by the external environment and extend the service life of the wire harness. The outermost outer protective layer 11 wraps around the outer wall of the anti-aging sheath layer 12, providing mechanical protection for the entire protective sleeve body 1 and resisting external scratches, wear and impact. The above multi-layer structure wraps and works together from the inside to the outside to form a complete protective system for the protective sleeve body 1, so that the wire harness can maintain good electrical performance and structural integrity even in harsh environments.

[0023] Reference Figure 2 The partition plate 4 divides the interior of the protective sleeve body 1 into multiple cavities. The wire core 3 is installed in each cavity, and a filler 5 is provided around the wire core 3 and inside the cavity. The filler 5 is made of waterproof paste material. During operation, the partition plate 4 extends along the axial direction of the protective sleeve body 1, dividing the internal space of the protective sleeve body 1 into multiple independent cavities. The wire core 3 is installed in each cavity, realizing the integrated wiring of multi-core wire harness. At the same time, the partition plate 4 physically isolates different wire cores 3, reducing the risk of insulation layer damage caused by mutual friction or compression of the wire cores 3 when bent, and effectively reducing the risk of short circuit between wires. Waterproof paste material is filled in each cavity and around the wire core 3 as filler 5. The waterproof paste has excellent water repellency and self-healing properties, and can fill all the tiny gaps between the wire core 3 and the inner wall of the cavity. When water attempts to penetrate along the axial direction inside the cavity, the waterproof paste can effectively prevent the capillary flow of water. At the same time, the waterproof paste also has a certain lubricating effect, allowing the wire core 3 to have a certain amount of movement in the cavity, improving the flexibility of the wire harness, and further enhancing the waterproof reliability inside the wire harness.

[0024] Reference Figure 1 - Figure 2A retaining ring 6 is fixedly connected to one end of the protective sleeve body 1. An annular groove 22 is formed on the inner wall of the end sleeve 2, and the retaining ring 6 is inserted into the inner wall of the annular groove 22. The protective sleeve body 1 and the retaining ring 6 are integrally formed. The sealing component and the retaining ring 6 are fixedly connected by hot pressing. During operation, in the assembly process of the sealing component, the end sleeve 2 is first placed on the end of the protective sleeve body 1, so that the integrally formed retaining ring 6 on the end of the protective sleeve body 1 is aligned with the annular groove 22 formed on the inner wall of the end sleeve 2. Then, the retaining ring 6 is inserted into the annular groove 22 to achieve the centering between the protective sleeve body 1 and the end sleeve 2. After the insertion is completed, the connection between the sealing component and the retaining ring 6 is heated and pressurized by hot pressing process, so that the material of the retaining ring 6 is heated and pressurized. Under pressure, the material softens and flows, filling the internal space of the annular groove 22. After cooling and solidification, it forms a firm fixed connection. This hot-pressing fixing method tightly integrates the insertion ring 6 with the annular groove 22, ensuring that the outer wall of the end sleeve 2 is flush with the outer wall of the protective sleeve body 1, and the inner wall of the end sleeve 2 is flush with the inner wall of the protective sleeve body 1. This ensures that the inner and outer walls of the connection between the end of the protective sleeve body 1 and the end sleeve 2 maintain a smooth transition, eliminating steps and gaps at the connection, reducing the risk of unevenness after assembly, and ensuring that the overall appearance of the wire harness end is flat and consistent. At the same time, the flat inner wall also reduces the risk of scratching and damaging the internal wire core 3, while the flat outer wall facilitates the installation of the wire harness in a limited space.

[0025] Reference Figure 2 and Figure 4 Multiple sets of sealing rings 23 are provided, and the multiple sets of sealing rings 23 are arranged at intervals along the axial direction of the extended sealing sleeve 21. During operation, when the wire core 3 is inserted through the inner wall of the extended sealing sleeve 21, the multiple sets of sealing rings 23 are sequentially sleeved on the outside of the wire core 3 along the axial direction. The inner wall of each set of sealing rings 23 forms a tight contact with the outer wall of the wire core 3. Since the sealing rings 23 are arranged at intervals along the axial direction, the multiple sets of sealing rings 23 together constitute a multi-stage series sealing structure. Even if the first sealing ring 23 experiences slight aging and leakage after long-term use, the subsequent sealing rings 23 can still effectively prevent moisture from continuing to seep in. At the same time, the structure of the spaced sealing rings 23 also allows the wire core 3 to maintain a certain degree of axial freedom of movement within the extended sealing sleeve 21, reducing the risk of stress concentration when the wire core 3 bends due to the excessive density of the sealing rings 23, thus balancing sealing reliability and wire harness flexibility.

[0026] Reference Figure 3 and Figure 5The outer protective layer 11 is made of nylon fiber, the anti-aging sheath layer 12 is made of cross-linked polyethylene, and the outer surface of the anti-aging sheath layer 12 is coated with an ultraviolet absorber. The waterproof sealing layer 13 is a heat-shrinkable waterproof sleeve, and the inner insulation layer 14 is a polyvinyl chloride insulation layer. During operation, the nylon fiber outer protective layer 11 has good wear resistance and tensile strength, effectively resisting external mechanical damage. The cross-linked polyethylene anti-aging sheath layer 12 utilizes its three-dimensional network molecular structure, exhibiting excellent dimensional stability and resistance to heat and oxygen aging in high-temperature environments. The ultraviolet absorber coated on its outer surface can absorb ultraviolet radiation from the protective layer. The ultraviolet light energy on the sheath surface is converted into heat energy or chemical energy, effectively inhibiting the breakage and damage of the molecular chain of the sheath by ultraviolet rays, and preventing the surface of the sheath from cracking and aging. The heat-shrinkable waterproof sleeve serves as a waterproof sealing layer 13. During assembly, it is heated to shrink and tightly adhere to the outer surface of the inner insulation layer 14, forming a uniform, continuous, and air-gap-free dense waterproof membrane layer. The polyvinyl chloride inner insulation layer 14 has good electrical insulation and processing performance, providing reliable basic electrical insulation protection for the wire core 3. The above-mentioned materials are selected according to their respective functional characteristics and work together in the protective sleeve body 1 to give the wire harness the characteristics of high sealing, aging resistance, and waterproofness.

[0027] Reference Figure 5 The support and reinforcement layer 15 is made of flexible insulating material. The inner wall of the support and reinforcement layer 15 is provided with annular corrugations. During operation, the support and reinforcement layer 15, made of flexible insulating material, covers the outer wall of the partition plate 4 and provides radial support for the internal structure of the entire protective sleeve body 1. The annular corrugations on its inner wall are continuously corrugated along the axial direction of the support and reinforcement layer 15. The crests of the annular corrugations abut against the outer wall of the partition plate 4, and the troughs form annular gaps between the crests and the outer wall of the partition plate 4. When the wire harness is subjected to external radial compressive force, the crests of the annular corrugations bear the pressure first. The force and elastic deformation disperse the pressure to the overall structure of the support and reinforcement layer 15, effectively buffering the external impact force and reducing the damage to the separator plate 4 and the internal wire core 3 caused by direct compression. At the same time, the annular gap formed at the trough of the annular wave pattern provides deformation space for the wire harness when bending, so that the support and reinforcement layer 15 can generate corresponding expansion and contraction deformation with the bending direction, improving the overall flexibility and bending resistance of the wire harness. In addition, the flexible insulation material properties of the support and reinforcement layer 15 ensure that it will not have an adverse effect on the electrical insulation performance of the internal wire core 3.

[0028] Working principle: The conductor 3 is installed inside the protective sleeve body 1, in a cavity formed by a partition plate 4, and the cavity is filled with waterproof paste as filler 5. The two ends of the conductor 3 pass through the through holes 24 of the end sleeve 2 and multiple sets of sealing rings 23 on the inner wall of the extended sealing sleeve 21 before being led out. The inner wall of the sealing ring 23 is tightly fitted to the outer wall of the conductor 3, forming multiple radial seals. At the same time, the frustum-shaped structure of the extended sealing sleeve 21 generates radial compression when it mates with the external mounting hole, achieving end sealing. The protective sleeve body 1 adopts a multi-layer composite structure, from the inside out: a support and reinforcement layer 15, an inner insulation layer 14, and a waterproof layer. The sealing layer 13, the anti-aging sheath layer 12, and the outer protective layer 11 provide structural support, electrical insulation, waterproof sealing, anti-aging and UV protection, and mechanical protection functions, respectively. The layers work together to form a complete protection system. The insertion ring 6 is inserted into the annular groove 22 on the inner wall of the end sleeve 2 and fixed by hot pressing, so that the sealing component and the protective sleeve body 1 are firmly connected as one, eliminating the assembly gap at the connection. This enables the end of the wire harness to have independent and reliable sealing and waterproof capabilities, effectively preventing moisture from seeping into the interior along the surface of the wire core 3 or the gaps between the layers, extending the service life of the wire harness and improving the safety of use.
