Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable head reinforced with insulating adhesive. Background Technology

[0002] As a core component of power systems and information transmission networks, cables are key conductor products specifically designed for conducting electrical energy and transmitting electrical signals. With their excellent conductivity, reliable insulation, and robust mechanical protection, cables occupy an irreplaceable position in various sectors of the national economy—widely applicable to multiple scenarios such as power transmission, communication transmission, transportation, industrial control, construction engineering, and the digital information industry. They undertake long-distance, high-capacity power transmission tasks, supporting the stable operation of urban infrastructure construction and industrial production, and are also responsible for the efficient transmission of various precision electrical signals, ensuring smooth information exchange. They are a crucial cornerstone for modern society's energy supply and the development of the digital economy.

[0003] In practical applications of cables, when connecting them to external electrical boxes, equipment interfaces, or other cables, the cable ends must be treated first. After peeling off the outer sheath, the internal conductive core is exposed, and then the terminals are assembled to ensure reliable circuit conduction. However, in existing technologies, terminals are typically connected to the conductive core only through crimping, welding, or simple threading, lacking a dedicated integrated reinforcement and protection structure for cable joints. On the one hand, the connection between the cable body and the terminal relies solely on the direct force between the conductive core and the terminal, making it susceptible to vibration, pulling, and environmental temperature changes during long-term use, leading to loosening, poor contact, and even power outages or signal interruptions. On the other hand, the sheath stripping area at the cable end and the connection between the conductive core and the terminal lack comprehensive protection, making them vulnerable to external dust, moisture, and corrosive gases. This not only reduces the insulation performance of the joint, increasing the risk of leakage and short circuits, but also accelerates the oxidation and aging of the conductive core, shortening the cable's lifespan. Furthermore, existing structures cannot effectively constrain the cable end, making it prone to bending under external forces, further exacerbating damage to the connection point and severely affecting the stability and reliability of the cable connection. Utility Model Content

[0004] To solve the above problems, this utility model provides a cable with cable head insulation adhesive reinforcement.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable head reinforced with insulating adhesive, comprising: The cable body has a conductive lower positioning block installed at one end. The top surface of the conductive lower positioning block has a lower positioning groove adapted to the conductive core inside the cable body. The conductive core at one end of the cable body is embedded in the lower positioning groove. A clamping assembly is disposed on the top of the conductive lower positioning block, and the clamping assembly is used to limit the conductive wire core in the lower positioning groove; A wiring terminal is fixedly connected to one end of the conductive lower positioning block; An insulating circular plate is fixedly connected to one end of the conductive lower positioning block; A threaded ring is fixedly connected to the outer wall of one side of the insulating circular plate; A reinforcement component is connected to the threaded ring, and one end of the reinforcement component is fixed to the cable body.

[0006] By adopting the above technical solution, after the conductive core at one end of the cable body is placed in the lower positioning groove, the conductive core can be positioned by the clamping assembly. After positioning, the fixing assembly can enhance the stability of the connection between the terminal and the cable body, and on the other hand, it can form a wrap-around protection for the end of the cable body.

[0007] Furthermore, the conductive lower positioning block, the clamping assembly, and the outer periphery of the cable body end are all wrapped with insulating tape to form an insulating coating layer.

[0008] By adopting the above technical solution, the insulation performance is increased by using insulating tape.

[0009] Furthermore, the clamping assembly includes an upper positioning block, which covers the top of the conductive lower positioning block, and the bottom surface of the upper positioning block has an upper positioning groove that corresponds to and matches the lower positioning groove.

[0010] By adopting the above technical solution, the conductive core at one end of the cable body can be positioned by the cooperation of the upper positioning groove and the lower positioning groove.

[0011] Furthermore, the upper positioning block has an installation groove along its length, and the groove wall of the installation groove and the corresponding position of the conductive lower positioning block both have threaded holes along their length. A positioning screw is threaded into the threaded hole to lock the upper positioning block and the conductive lower positioning block together.

[0012] By adopting the above technical solution, the upper positioning block and the conductive lower positioning block are fixed as a whole by the positioning screw.

[0013] Furthermore, the reinforcing component includes an external threaded cylinder, one end of which is threadedly connected to the threaded ring, and the other end of which is threadedly connected to an internal threaded cylinder on its inner circumference.

[0014] By adopting the above technical solution, the external threaded cylinder can be connected to the threaded ring via threads.

[0015] Furthermore, clamps are symmetrically arranged on the outer surface of the cable body, and a pair of clamps are positioned on the outer surface of the cable body by fixing bolts.

[0016] By adopting the above technical solution, a pair of clamps can be fastened to the cable body.

[0017] Furthermore, a semi-circular threaded plate is fixed to the outer periphery of each pair of clamps, and the end of the inner threaded cylinder away from the outer threaded cylinder is threadedly connected to the semi-circular threaded plate.

[0018] By adopting the above technical solution, the internal threaded cylinder can be threadedly mated with the semi-circular threaded plate.

[0019] Furthermore, the end of the wiring terminal away from the conductive lower positioning block passes through the insulating circular plate and extends outward.

[0020] By adopting the above technical solution, the terminal blocks can be easily connected to external devices.

[0021] In summary, this utility model has the following beneficial effects: by setting up a reinforcement component, the conductive core inside one end of the cable body is fixed to the conductive lower positioning block by the clamping component and wrapped with insulating tape, and the reinforcement component is assembled. This not only significantly improves the mechanical stability of the connection between the terminal and the cable body, but also forms a comprehensive wrapping protection for the end of the cable body. This not only ensures the reinforcement reliability of the connection node, but also greatly reduces the risk of the terminal and the conductive core becoming loose, further improving the overall operational safety and service life of the cable.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-7 As shown in the figure, this application discloses a cable head insulation-reinforced cable, including a cable body 1, a conductive lower positioning block 2 mounted on one end of the cable body 1, a lower positioning groove adapted to the conductive core inside the cable body 1 on the top surface of the conductive lower positioning block 2, and the conductive core at one end of the cable body 1 embedded in the lower positioning groove; a clamping assembly 3 disposed on the top of the conductive lower positioning block 2, the clamping assembly 3 being used to limit the conductive core in the lower positioning groove; a terminal block 4 fixedly connected to one end of the conductive lower positioning block 2; an insulating circular plate 5 fixedly connected to one end of the conductive lower positioning block 2; a threaded ring 6 fixedly connected to the outer side wall of one side of the insulating circular plate 5; and a reinforcement assembly 7 connected to the threaded ring 6, with one end of the reinforcement assembly 7 fixed to the cable body 1.

[0025] In use, the conductive core at one end of the cable body 1 is first stripped and embedded into the lower positioning groove of the conductive lower positioning block 2. The conductive core is then locked from the top by the clamping assembly 3, achieving tight positioning between the conductive core and the conductive lower positioning block 2. Next, the circuit connection with external equipment is completed through the terminal block 4, and the insulating round plate 5 simultaneously provides basic insulation protection for the connection part. Finally, the reinforcement assembly 7 is assembled and fixed by the threaded ring 6, with one end fixed to the outer surface of the cable body 1, forming a full-process reinforcement from the positioning of the conductive core to the fixing of the cable body 1. This structure not only greatly improves the mechanical strength of the connection part between the terminal block 4 and the conductive core through the double fixing of the clamping assembly 3 and the reinforcement assembly 7, but also strengthens the insulation performance of the cable head through the covering of the insulating round plate 5 and the subsequently compatible insulating tape 8. This avoids the problems of the conductive core loosening and the terminal block 4 loosening, and reduces the bending damage of the cable end caused by external force, significantly improving the reliability and service life of the cable connection.

[0026] Insulating tape 8 is wrapped around the outer periphery of the conductive lower positioning block 2, the clamping assembly 3, and the end of the cable body 1 to form an insulating coating layer. After the conductive core inside the cable body 1 is positioned and clamped with the conductive lower positioning block 2 and the terminal 4 is assembled, insulating tape 8 is wrapped around the outer periphery of the conductive lower positioning block 2, the clamping assembly 3, and the end of the cable body 1. This ensures that the insulating tape 8 is tightly attached to the surface of each component and forms a complete insulating coating layer. This insulating coating layer not only fully covers the conductive core inside the cable body 1, the connection between the conductive lower positioning block 2 and the clamping assembly 3, and the sheath cut at the end of the cable body 1, filling the gaps between the components and blocking leakage paths, but also enhances the integrity of the conductive lower positioning block 2, the clamping assembly 3, and the end of the cable body 1, reducing relative displacement caused by external vibration. At the same time, it provides dustproof and moisture-proof protection, preventing external impurities or moisture from entering and causing a decrease in the insulation performance of the cable head, further improving the insulation reliability and safety of the cable head, and extending the service life of the cable head connection node.

[0027] The clamping assembly 3 includes an upper positioning block 301, which covers the top of the conductive lower positioning block 2. The bottom surface of the upper positioning block 301 is provided with an upper positioning groove that corresponds to and matches the lower positioning groove. The upper positioning block 301 is provided with an installation groove along its length. The groove wall of the installation groove and the corresponding position of the conductive lower positioning block 2 are provided with threaded holes along the length. The threaded holes are threaded with positioning screws 302 to lock the upper positioning block 301 and the conductive lower positioning block 2.

[0028] In use, after the conductive core inside the cable body 1 is embedded in the lower positioning groove of the conductive lower positioning block 2, the upper positioning block 301 is precisely placed on top of the conductive lower positioning block 2, so that the upper positioning groove and the lower positioning groove form a closed and limiting space for the conductive core. Then, the positioning screw 302 is passed through the groove wall of the mounting slot and the threaded hole of the conductive lower positioning block 2 and tightened. Through the locking force of the positioning screw 302, the upper positioning block 301 is driven to fit tightly with the conductive lower positioning block 2, which not only achieves radial clamping and axial limiting of the conductive core, preventing the conductive core from shifting or moving during the connection process, but also ensures the stability of the conductive contact between the conductive core and the conductive lower positioning block 2 and the terminal 4.

[0029] The reinforcement component 7 includes an external threaded cylinder 701. One end of the external threaded cylinder 701 is threadedly connected to the threaded ring 6. The other end of the external threaded cylinder 701 is threadedly connected to an internal threaded cylinder 702 on its inner circumference. A pair of clamps 703 are symmetrically arranged on the outer surface of the cable body 1. A pair of clamps 703 are positioned on the outer surface of the cable body 1 by fixing bolts 704. A semi-circular threaded plate 705 is fixedly connected to the outer circumference of each pair of clamps 703. The end of the internal threaded cylinder 702 away from the external threaded cylinder 701 is threadedly connected to the semi-circular threaded plate 705.

[0030] Before connecting the conductive core inside the cable body 1 to the conductive lower positioning block 2, the external threaded cylinder 701 and the internal threaded cylinder 702 should be sequentially fitted onto the outside of the cable body 1. After the conductive core inside the cable body 1 is fixed to the conductive lower positioning block 2 by the clamping assembly 3 and the insulating tape 8 is wrapped around it, the external threaded cylinder 701 should be moved toward the conductive lower positioning block 2 to make it precisely threadedly connected and fixed with the threaded ring 6 on the insulating circular plate 5. Then, a pair of clamps 703 should be symmetrically attached to the outer surface of the corresponding position of the cable body 1 and tightened. The fixing bolt 704 tightly clamps the clamp 703 to the cable body 1, achieving a stable assembly between the clamp 703 and the cable body 1. Finally, the inner threaded cylinder 702 is rotated so that the end away from the outer threaded cylinder 701 is threadedly connected and locked to the semi-circular threaded plate 705 on the outer periphery of the clamp 703, forming a continuous reinforcement structure from the insulating circular plate 5 to the cable body 1. This not only provides comprehensive protection for the ends and connection nodes of the cable body 1, but also further enhances the connection stability between the terminal 4 and the conductive core, significantly reducing the risk of loosening and extending the overall reliability of the cable.

[0031] The end of the terminal block 4 away from the conductive lower positioning block 2 passes through the insulating circular plate 5 and extends outward. The terminal block 4 provides ample space for docking with external electrical boxes and other equipment, improving the ease of assembly.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
