Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, and in particular to a fully enclosed sealed wire clamp. Background Technology

[0002] In existing technologies, to prevent short circuits between cables and bolts caused by external moisture intrusion when clamping cables, a sealing sleeve is typically added to the outside of the clamp to completely enclose the clamp, and the exposed portion of the bolts is covered with insulating material. While this structure blocks direct contact with moisture to some extent, a gap still exists between the exposed bolt portion and the corresponding mating hole on the clamp body. Moisture can still seep into the clamp through this gap, and over time, it can easily form conductive paths in humid or polluted environments, leading to electrical short circuits. Utility Model Content

[0003] The main purpose of this utility model is to propose a fully enclosed sealing wire clamp, which aims to achieve all-round sealing between the wire clamp and the bolt, improve the sealing performance of the wire clamp, and thus avoid electrical short circuit problems.

[0004] To achieve the above objectives, this utility model proposes a fully enclosed sealing wire clamp, the fully enclosed sealing wire clamp comprising:

[0005] In one embodiment, the fully enclosed sealed clamp includes a clamp body and a sealing bolt, and also includes an insulating protective sleeve, which is fixedly covered to the outside of the clamp body;

[0006] The outer wall of the insulating protective sleeve has a protruding cylindrical body corresponding to the installation position of the sealing bolt, and a channel is formed inside the cylindrical body for the sealing bolt to pass through.

[0007] The head of the sealing bolt is provided with a cover portion. When the sealing bolt is tightened to the installation position, the cover portion fits into the top end of the cylinder to make the sealing bolt and the insulating protective sleeve seal together.

[0008] In one embodiment, the cover portion is a sleeve structure extending downward from the bolt head, and the inner diameter of the cover portion is adapted to the outer diameter of the cylinder body so that the cover portion is fitted onto the outside of the cylinder body.

[0009] In one embodiment, the height of the cover portion is greater than the height of the cylinder body.

[0010] In one embodiment, the cover portion is an annular wall extending downward from the bolt head, and the outer diameter of the cover portion is adapted to the inner diameter of the cylinder body so that the cover portion can be inserted into the interior of the cylinder body.

[0011] In one embodiment, at least one annular sealing ring is provided on the contact surface between the cover and the cylinder.

[0012] In one embodiment, the inner wall of the cylinder is provided with internal threads, and the screw of the sealing bolt is provided with external threads that match the internal threads.

[0013] In one embodiment, after the screw of the sealing bolt is screwed into the cylinder, the end of the screw of the sealing bolt is connected to the conductive clamping component in the clamp body, and the threaded engagement between the screw of the sealing bolt and the inner wall of the cylinder is filled with waterproof sealant.

[0014] In one embodiment, the cover portion is integrally formed with the head of the sealing bolt.

[0015] In one embodiment, the protective sleeve is integrally molded onto the outside of the clamp body using an injection molding process.

[0016] In one embodiment, the protective sleeve is made of one of rubber, silicone, or thermoplastic elastomer.

[0017] The technical solution of this utility model adopts an insulating protective sleeve that is fixedly covered on the outside of the clamp body, and sets a cylindrical body with a channel on the protective sleeve corresponding to the position of the sealing bolt. At the same time, the head of the sealing bolt forms a cover part that can fit with the top of the cylindrical body. Thus, when the bolt is tightened, it achieves all-round, gapless sealing of the connection between the clamp and the bolt, effectively preventing the intrusion of external moisture and pollutants, completely eliminating the potential electrical short circuit hazard caused by moisture or conductive medium accumulation, and significantly improving the insulation reliability and long-term safety of the clamp in complex environments.

[0028] Please see Figures 1 to 3This application proposes a fully enclosed sealed wire clamp, including a wire clamp body 10 and a sealing bolt 20, and also includes an insulating protective sleeve 30, which is fixedly covered on the outside of the wire clamp body 10; wherein, the outer wall of the insulating protective sleeve 30 has a protruding cylindrical body 31 corresponding to the installation position of the sealing bolt 20, and a channel 31a is formed inside the cylindrical body 31 for the sealing bolt 20 to pass through; the head of the sealing bolt 20 is provided with a cover part 21, and when the sealing bolt 20 is tightened to the installation position, the cover part 21 and the top end of the cylindrical body 31 fit together to make the sealing bolt 20 and the insulating protective sleeve 30 sealed together.

[0029] In practical applications, the insulating protective sleeve 30 can be understood as a protective structure covering the outside of the clamp body 10. Its main function is to isolate the clamp body 10 from the influence of the external environment through a continuous covering layer. Specifically, the insulating protective sleeve 30 can be fixedly connected to the clamp body 10 through injection molding, hot pressing, or compression molding. For example, a multi-segment injection molding method can be used to combine the protective sleeve with the clamp body 10, or a mechanical snap-fit ​​structure can be used to achieve a fixed assembly of the two. Its main purpose is to achieve initial isolation from external moisture.

[0030] Furthermore, the cylinder 31 can be understood as a hollow structure extending from the outer wall of the insulating protective sleeve 30, with the channel 31a formed inside to accommodate the passage path of the sealing bolt 20. Specifically, the cylinder 31 can be integrally formed with the insulating protective sleeve 30 through injection molding, or it can be assembled with the insulating protective sleeve 30 after separate processing, for example, by using threaded connection or interference fit to fix the cylinder 31 to the insulating protective sleeve 30, mainly to achieve precise matching of the installation path of the sealing bolt 20.

[0031] Specifically, the cover portion 21 can be understood as an additional structure set on the head of the sealing bolt 20, and its main function is to form a tight fit with the cylinder 31 when the sealing bolt 20 is tightened. The innovation of this application lies in the fact that through the coordinated design of the insulating protective sleeve 30, the cylinder 31, and the cover portion 21, the problem of moisture seeping into the wire clamp along the gap caused by the assembly gap between the exposed section of the bolt and the mating hole of the wire clamp body 10 is solved. Compared with the existing technology that only relies on a simple sealing sleeve, this application automatically completes the sealing interface during the bolt tightening process through the fitting structure of the cylinder 31 and the cover portion 21, thereby effectively blocking the possibility of moisture seeping into the wire clamp along the bolt path.

[0032] The working principle of this embodiment is as follows: A fully enclosed sealed cable clamp achieves the clamping function of cables through the cooperation of the clamp body 10 and the sealing bolt 20, while introducing an insulating protective sleeve 30 to solve the problem of moisture seeping in along the bolt installation path. The insulating protective sleeve 30 is fixedly covered on the outside of the clamp body 10, forming a continuous insulating barrier, thereby initially isolating direct contact with external moisture. Further, the outer wall of the insulating protective sleeve 30 has a protruding cylindrical body 31 at the corresponding installation position of the sealing bolt 20, and the inside of the cylindrical body 31 forms a channel 31a for the sealing bolt 20 to pass through. The design of this channel 31a allows the sealing bolt 20 to pass through normally, while the wall thickness constraint of the cylindrical body 31 reduces the exposed area of ​​the bolt to the outside, transforming the originally open gap into a controllable sealing interface.

[0033] The head of the sealing bolt 20 is provided with a cover portion 21. When the sealing bolt 20 is tightened to the installation position, the cover portion 21 and the top end of the cylinder 31 fit together. Specifically, this design utilizes the mechanical displacement of the bolt tightening action to automatically trigger the sealing mechanism, ensuring a tight fit between the cover portion 21 and the cylinder 31. Thus, the tightening process and interface sealing are completed simultaneously, eliminating residual gaps at the connection point without additional operation. The unique feature of this structure is its ability to completely block the possibility of moisture penetrating into the clamp along the bolt installation path, thereby avoiding the risk of short circuits caused by the formation of conductive paths in humid environments.

[0034] Please see Figures 1 to 3 Furthermore, this application proposes that the cover portion 21 is a sleeve structure extending downward from the bolt head, and the inner diameter of the cover portion 21 is adapted to the outer diameter of the cylinder 31 so that the cover portion 21 is fitted onto the outside of the cylinder 31.

[0035] Specifically, the cover portion 21 refers to the complete wrapping layer continuously extending downwards from the head of the sealing bolt 20, which can be achieved using a sleeve structure made of metal or high-strength plastic. This design ensures the continuity and integrity of the coverage area, avoiding partial exposure that could lead to moisture intrusion. The matching of the inner diameter of the cover portion 21 with the outer diameter of the cylinder 31 is designed to create a tight fit during assembly. This dimensional matching eliminates the minute gaps that may exist in traditional simple cover structures, thereby blocking the channel 31a through which moisture permeates along the mating surface.

[0036] In detail, in the aforementioned fully enclosed sealed clamp, a tight fit is achieved by designing the cover portion 21 as a sleeve structure and adapting its inner diameter to the outer diameter of the cylinder 31. This design transfers the sealing interface to the outer wall of the cylinder 31, and combined with the extension characteristics of the sleeve structure, the sealing effect is concentrated on the outside of the cylinder 31 rather than the internal gaps. Furthermore, since the cover portion 21 extends directly from the head of the sealing bolt 20, this integrated design not only simplifies the assembly process but also enhances the overall structural stability. When the cover portion 21 is fitted onto the outside of the cylinder 31, its tight fit, combined with the protective function of the insulating sleeve 30, significantly improves the overall sealing reliability under tightened conditions, ultimately preventing moisture from seeping into the clamp and causing a short circuit.

[0037] The above technical solution effectively solves the technical defect of poor sealing between the cover 21 and the cylinder 31, and significantly improves the reliability of the wire clamp in humid environments.

[0038] Please see Figures 1 to 3 This application further proposes that the height of the cover 21 is greater than the height of the cylinder 31.

[0039] Specifically, the height of the cover 21 is designed to be greater than the height of the cylinder 31, in order to ensure that the two can form a complete covering relationship during assembly. In practical applications, this height difference design can be achieved through processes such as precision machining or mold forming to ensure dimensional accuracy and assembly effect.

[0040] Specifically, by designing a height difference between the cover 21 and the cylinder 31, the cover 21 can completely cover the entire height range of the cylinder 31 when fitted onto it. During the tightening of the sealing bolts 20, the cover 21 and the top of the cylinder 31 form a tight, gapless fit, effectively blocking potential water vapor infiltration paths along the height direction. This design prevents water vapor intrusion due to insufficient height and avoids material wrinkling or localized stress concentration problems caused by excessive height.

[0041] This application further proposes that the cover portion 21 is an annular wall extending downward from the bolt head, and the outer diameter of the cover portion 21 is adapted to the inner diameter of the cylinder 31 so that the cover portion 21 can be inserted into the interior of the cylinder 31.

[0042] Specifically, the cover portion 21 refers to an annular structure extending downwards from the head of the sealing bolt 20. Its main function is to improve sealing performance by changing the way it fits with the cylinder 31. In practical applications, the cover portion 21 can be made of metal or high-strength engineering plastic, and its outer diameter must be strictly matched with the inner diameter of the cylinder 31 to ensure a tight fit during assembly. The purpose of this design is to eliminate any tiny gaps that may occur during external fitting, thereby effectively blocking the path of water vapor intrusion.

[0043] In detail, this technical solution fundamentally solves the sealing problem caused by traditional external fittings by designing the cover 21 as an annular wall structure and inserting it into the cylinder 31. The annular wall shape of the cover 21 allows it to be directly embedded into the cylinder 31, avoiding the formation of microchannels 31a due to misalignment or vibration. Simultaneously, the fit between the outer diameter of the cover 21 and the inner diameter of the cylinder 31 ensures dimensional matching during assembly, eliminating potential assembly gaps through precise tolerance control. Furthermore, the inner wall of the cylinder 31 provides all-around constraint to the annular wall, maintaining a uniform pressure distribution even under temperature changes or mechanical stress, thereby further enhancing the sealing effect. Based on this, the overall structure of the aforementioned fully enclosed sealing clamp is optimized, exhibiting particularly reliable electrical insulation performance in humid or polluted environments.

[0044] Please see Figures 1 to 3 This application further proposes that at least one annular sealing ring 40 is provided on the contact surface between the cover 21 and the cylinder 31.

[0045] Specifically, the annular seal 40 refers to an elastic sealing element with a closed annular structure, which can be made of elastic materials such as rubber, silicone, or polyurethane, and is designed to fill assembly gaps through elastic deformation. The cross-sectional shape of the annular seal 40 can be circular, square, or other adaptable shapes to meet the pressure distribution requirements of different contact surfaces. At least one design element is intended to provide redundant sealing protection, ensuring stable sealing performance under dynamic operating conditions.

[0046] When the cover 21 and the cylinder 31 are fitted together, the annular sealing ring 40 is compressed and undergoes elastic deformation, tightly fitting the annular contour of the contact surface, thus effectively filling any possible assembly gaps. Because the annular sealing ring 40 distributes pressure evenly along its entire circumference, it forms a continuous sealing barrier, preventing water vapor from penetrating circumferentially along the contact surface. Especially under conditions of vibration or temperature changes, the multiple annular sealing rings 40 ensure that even if a localized stress change occurs at one point, other locations maintain an effective seal, avoiding a decline in overall sealing performance due to single-point failure. This design directly addresses the inherent defects in the gap between the cover 21 and the cylinder 31, completely blocking potential water seepage paths and significantly improving overall sealing reliability.

[0047] Through the above technical solution, the multiple sealing mechanism formed between the cover 21 and the cylinder 31 not only solves the problem of water vapor seeping in along the assembly gap, but also adapts to stress changes under different working conditions through the elastic characteristics of the sealing ring, fundamentally suppressing the electrical short circuit hazard caused by water vapor intrusion.

[0048] Please see Figures 1 to 3This application further proposes that the inner wall of the cylinder 31 is provided with internal threads, and the screw of the sealing bolt 20 is provided with external threads that match the internal threads.

[0049] Specifically, the internal thread refers to the helical groove structure machined into the inner wall of the cylinder 31, which can be achieved by machining, roll forming, or injection molding. The purpose of the internal thread is to provide a precise screw-in path for the sealing bolt 20, ensuring a tight fit between the threads. The external thread refers to the helical protrusion structure machined into the outer surface of the sealing bolt 20, which can be achieved by turning, thread rolling, or other processes. The design of the matching external thread aims to eliminate assembly gaps and form a continuous sealing interface through engagement with the internal thread.

[0050] Specifically, when the sealing bolt 20 is screwed into the cylinder 31, the internal thread provides a precise thread path, allowing the external thread of the bolt to fully engage. This threaded engagement not only enhances the stability of the connection but also fundamentally solves the problem of moisture seepage along the threads by eliminating the root cause of gaps. During tightening, the interlocking threads tightly fill any tiny gaps that might otherwise exist, forming a continuous sealing interface that prevents moisture intrusion. Furthermore, this threaded engagement design effectively improves assembly efficiency and connection reliability, making it particularly suitable for wire clamp devices that require long-term use in humid environments.

[0051] Please see Figures 1 to 3 This application further proposes that after the screw of the sealing bolt 20 is screwed into the cylinder 31, the end of the screw of the sealing bolt 20 is connected to the conductive clamping component in the wire clamp body 10, and the threaded engagement between the screw of the sealing bolt 20 and the inner wall of the cylinder 31 is filled with waterproof sealant.

[0052] Specifically, waterproof sealant refers to a sealing material with fluidity and curing ability, which can be implemented using silicone sealant, polyurethane sealant, or epoxy resin sealant. Its purpose is to form a continuous and dense physical barrier by filling the irregular micro-gap at the threaded joint, thereby blocking the intrusion channel 31a of water vapor along the thread path. Conductive clamping components refer to metal structural parts used to clamp and conduct cables. They can be implemented using copper clips or aluminum clips. Their purpose is to ensure the reliability of electrical functions and provide a stable installation reference for the sealing bolt 20.

[0053] By filling the threaded joint with waterproof sealant, its fluidity allows it to completely cover uneven areas of the thread surface, forming a dense sealing layer after curing. This effectively solves the problem of water vapor penetration caused by the inherent gaps in the threaded connection. The connection between the screw end and the conductive clamping component not only ensures stable electrical performance but also provides a precise positioning reference for the sealing bolt 20, fixing its position during screwing and facilitating subsequent sealing operations. Furthermore, the introduction of waterproof sealant compensates for the shortcomings of the mechanical connection, significantly improving the overall sealing performance of the clamp, especially suitable for applications in humid or polluted environments.

[0054] Based on this, the aforementioned fully enclosed sealed clamp, by combining waterproof sealant with threaded connection, not only solves the problem of water vapor penetration that may be caused by assembly gaps, but also optimizes the sealing effect of mechanical connection through material properties, thereby avoiding the risk of forming a conductive path due to environmental factors.

[0055] Please see Figures 1 to 3 This application further proposes that the head of the cover 21 and the sealing bolt 20 are integrally formed.

[0056] Specifically, the cover portion 21 refers to the structural component extending from the head of the sealing bolt 20, which can be manufactured integrally with the head of the sealing bolt 20 through injection molding, casting, or machining. This design effectively eliminates assembly gaps that may exist in separate connections, thereby blocking the path of moisture and air entering the clamp along this interface. The purpose of introducing this technical feature is to fundamentally improve sealing performance and ensure the reliability of electrical isolation.

[0057] By designing the cover portion 21 and the head of the sealing bolt 20 as a single integral component, the problem of minute gaps caused by part tolerances, material shrinkage, or assembly stress in traditional split structures is eliminated. In practical applications, when the sealing bolt 20 is tightened to the installation position, the cover portion 21 and the top of the cylinder 31 form a continuous and defect-free sealing interface. The special feature of this design is that it not only simplifies the manufacturing process but also enhances the overall sealing performance between the sealing bolt 20 and the insulating protective sleeve 30. This ensures reliable electrical isolation even under long-term exposure to humid or polluted environments, preventing moisture from entering conductive components along the bolt path and causing short circuits.

[0058] This application further proposes that the protective sleeve be integrally molded outside the clamp body 10 by injection molding.

[0059] Injection molding refers to the process of injecting molten material into a mold and allowing it to solidify. This can be achieved by using high-precision molds and controlling injection parameters. The protective sleeve can be injection molded from materials such as rubber, silicone, or thermoplastic elastomers to ensure a continuous and uninterrupted integral structure between the protective sleeve and the clamp body 10.

[0060] Specifically, this technical solution uses injection molding to directly form the protective sleeve onto the exterior of the clamp body 10, eliminating the interface gap problem inherent in traditional assembly methods. In practical applications, the molten protective sleeve material is precisely filled into every detail of the clamp body 10 surface under high pressure, including minute grooves and corners, achieving a perfect fit. This tightly fitted structure effectively blocks the intrusion channel 31a of external moisture into the clamp, significantly improving sealing reliability. Furthermore, since injection molding is completed in one step without additional fixing steps, it simplifies the production process and improves production efficiency. When this solution is applied to the aforementioned fully enclosed sealed clamp, it better complements the cylindrical structure 31 of the insulating protective sleeve 30 and the connection method of the sealing bolts 20, jointly constructing a complete sealing and protection system, thereby avoiding potential electrical faults caused by moisture accumulation during long-term use.

[0061] Please see Figures 1 to 3 This application further proposes that the protective cover be made of one of the following materials: rubber, silicone, or thermoplastic elastomer.

[0062] Specifically, the protective sleeve refers to a key component used to fully enclose the clamp body 10 and achieve a sealing function. In practical applications, the protective sleeve can be made of rubber, silicone, or thermoplastic elastomer. Due to the flexibility and hydrophobicity of its polymer chains, rubber can effectively block the penetration of water molecules in humid environments; silicone, with its excellent temperature resistance and chemical stability, can maintain a stable sealing effect under extreme temperature conditions; thermoplastic elastomers combine the processability of thermoplastic materials with the elastic recovery ability of rubber, ensuring precise fit to the clamp body 10 during injection molding while resisting performance degradation caused by ultraviolet radiation, ozone, and temperature cycling over a long period of time.

[0063] Based on this, the design of the protective sleeve material, the clamp body 10, and the sealing bolts 20 work together to form a complete sealing system. The protective sleeve is integrally molded onto the clamp body 10 using an injection molding process. Its material elasticity and environmental resistance ensure good sealing performance even after long-term exposure to humid, polluted, or temperature-fluctuating environments. Simultaneously, the annular sealing ring 40 at the contact surface between the cover 21 and the cylinder 31 further enhances the sealing performance, effectively preventing moisture from seeping into the clamp along the assembly gap. This design significantly reduces the risk of electrical short circuits, making it particularly suitable for long-term stable operation under harsh conditions.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
