Description

Technical Field

[0001] This utility model relates to the field of cable insulation sheath technology, and in particular to a reusable soft insulation sheath suitable for various types of cables. Background Technology

[0002] Cable insulation sheath is a protective layer wrapped around the cable insulation layer. Its main function is to protect the cable insulation layer from external mechanical damage, chemical corrosion, moisture intrusion and other hazards. At the same time, it can also prevent the internal conductor of the cable from being adversely affected by the external environment to a certain extent.

[0003] During power maintenance and repair, line adjustments and modifications are often involved, which can lead to dangerous situations such as exposed wire ends. Live-line work in such cases can easily result in safety accidents. Currently, there are two main methods: one is to wrap insulating tape around the wire ends, which is then removed before installation. Using insulating tape is inefficient, requiring repeated wrapping and tearing. The second method is to install insulating sleeves at the wire ends. However, existing insulating sleeves have model matching issues. Each different cable model requires a corresponding insulating sleeve, and model mismatch can leave exposed areas, increasing the risk of wet flashover and contamination flashover. Furthermore, they have weak pull-out resistance, making them prone to displacement or detachment under external force, resulting in exposed terminals. They are also not reusable, and most insulating sleeves are easily damaged after removal and cannot be repaired.

[0004] Therefore, those skilled in the art are dedicated to developing a reusable insulating soft sheath suitable for various cable types, which is beneficial for protecting cable ends and is easy to operate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a reusable insulating soft sheath applicable to various types of cables, which is beneficial for protecting the wire ends and is easy to operate.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A reusable insulating soft sheath suitable for various cable types, including A protective sleeve assembly having a receiving cavity for accommodating the end of a wire; A locking assembly is installed at the end of the protective sleeve assembly and is used to lock and fix the protective sleeve assembly to the wire end.

[0007] The beneficial effects of adopting the above solution are: the protective sleeve assembly has a receiving cavity, which can flexibly accommodate the wire ends of different types of cables, and solves the problem of difficulty in matching existing soft insulating sheaths and the easy leaving of exposed areas; The locking assembly is installed at the end of the protective sleeve assembly to lock the protective sleeve to the wire end, effectively preventing the protective sleeve from shifting or falling off when subjected to external force. Compared with the inefficient operation of repeatedly wrapping and tearing the insulating tape, this structure makes the installation and removal of the protective sleeve more convenient, and improves the efficiency and safety of wire end insulation protection in power maintenance and repair.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the protective sleeve assembly includes a protective sleeve, and the engaging assembly is mounted on the end of the protective sleeve.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: the protective sleeve prevents damage to the wire ends from external mechanical damage, chemical corrosion, moisture intrusion, etc., and can adapt to a variety of complex environmental conditions, ensuring that it can stably perform its protective function in different usage scenarios. Moreover, it can maintain its performance after multiple installations and disassemblies, extending its service life, meeting the requirements of reusability, and reducing maintenance costs.

[0011] Furthermore, the engaging assembly includes a first connector and a second connector, which are respectively installed on both sides of the end of the protective sleeve assembly, and are connected by a spring clip assembly.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: When encountering cable ends of different diameters, the spring clip assembly can generate corresponding deformation, so that the first and second connecting parts fit tightly against the cable end, achieving self-adaptive locking and fixing. There is no need to equip each type of cable with a matching sheath, which greatly improves the versatility of the sheath and meets the insulation protection requirements of various types of cables. At the same time, it enhances the pull-out resistance, effectively preventing the sheath from shifting or falling off under the action of external force, ensuring that the cable end is always in a reliable state of insulation protection. In power maintenance and repair work, it can quickly adapt to various types of cable ends, improving work efficiency.

[0013] Furthermore, both the first connector and the second connector are arc-shaped.

[0014] The beneficial effects of adopting the above-mentioned further solution are: both the first connector and the second connector are arc-shaped, and the arc shape fits the curved contour of the cable end, making the contact and wrapping of the locking component with the cable end better and the force more even.

[0015] Furthermore, the spring clip assembly includes a first clamping member and a second clamping member, with the end of the first clamping member passing through the first connecting member and the end of the second clamping member passing through the second connecting member, and the middle portions of the first clamping member and the second clamping member being hinged together by a hinge member.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: The hinged spring clip assembly structure allows the first and second clamping parts to open and close flexibly within a certain angle range. When the sheath needs to be installed, only moderate force needs to be applied to open the first and second clamping parts, and the cable end can be easily inserted. After being released, it automatically returns to its clamping position under the elastic restoring force of the spring clip assembly. The operation is simple and labor-saving, which greatly improves the installation efficiency. Moreover, by adjusting the opening and closing degree of the clamping parts, it can better adapt to the clamping requirements of wire ends of different thicknesses, making the sheath's compatibility range wider. At the same time, it ensures that the clamping force is evenly distributed, further improving the connection reliability between the sheath and the wire end, reducing the risk of displacement and detachment, and strengthening the insulation protection performance.

[0017] Furthermore, both the first clamping member and the second clamping member include a clamping arc, which passes through the first connector or the second connector. The clamping arc is connected to a clamping rod, and the hinge is installed at the connection between the clamping arc and the clamping rod.

[0018] The beneficial effects of adopting the above-mentioned further solutions are as follows: the clamping arc increases the contact area with the connector, improving the stability of the connection, enabling the spring clip assembly to maintain a more stable fit with the connector when under force, reducing the risk of loosening and falling off; the clamping rod extends the length of the clamping component, providing a foundation for the installation of subsequent auxiliary clamping components, making the structure of the entire locking assembly more reasonable, and enabling it to fix the sheath to the wire end more accurately and powerfully, further optimizing the fixing effect of the sheath, enhancing its stability in complex environments and under external force interference, and ensuring the insulation safety of the wire end.

[0019] Furthermore, an auxiliary clamping component is also connected to the end of the clamping rod.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the auxiliary clamping component makes it easier for the operator to hold and operate the first clamping component and the second clamping component.

[0021] Furthermore, the protective cover is made of silicone.

[0022] The beneficial effects of adopting the above-mentioned further solutions are: silicone has electrical insulation capabilities, is resistant to high and low temperatures and has good corrosion resistance, and can adapt to various complex outdoor and indoor environments as well as power maintenance operations under various harsh climatic conditions, and can maintain stable performance even after long-term use.

Therefore, they should not be construed as limitations on this invention.

[0027] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a reusable insulating soft sheath suitable for various cable types includes a protective sheath assembly 1. The protective sheath assembly 1 has a receiving cavity 3 for accommodating the end of the wire head 2. The protective sheath assembly 1 is elastic, and by reasonably adjusting the shape and size of the receiving cavity 3, it can ensure that the ends of wire heads 2 of different specifications can be flexibly inserted, thereby avoiding the problem of exposed wire heads due to mismatch in sheath size.

[0030] The engaging component 4 is installed at the end of the protective sleeve component 1. The engaging component 4 is used to engage and fix the protective sleeve component 1 with the wire end 2. The elastic deformation of the engaging component 4 can adapt to wire ends 2 of different diameters, thereby achieving reliable fixation and effectively preventing the protective sleeve from shifting or falling off under the action of external force.

[0031] like Figure 1 , Figure 2 As shown, in some embodiments, the protective sleeve assembly 1 includes a protective sleeve 5, and a snap-fit ​​assembly 4 is installed at the end of the protective sleeve 5. The protective sleeve 5 is made of silicone. The silicone material gives the protective sleeve 5 good elasticity and weather resistance, enabling it to maintain stable performance under various environmental conditions. At the same time, it has a certain degree of flexibility, making it easy to install and remove, and it can still maintain good insulation and protection after multiple uses.

[0032] like Figure 1 ,like Figure 2 and Figure 3 As shown, in another embodiment, the locking assembly 4 includes a first connector 6 and a second connector 7. The first connector 6 and the second connector 7 are integrally formed with the protective sleeve 5. Both the first connector 6 and the second connector 7 are arc-shaped, and the arc shape conforms to the curved contour of the cable end 2, making the contact area between the locking assembly 4 and the cable end 2 larger and the force more even, thereby enhancing the fixing effect. The first connector 6 and the second connector 7 are respectively installed on both sides of the end of the protective sleeve assembly 1, and the first connector 6 and the second connector 7 are connected by a spring clip assembly 8.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the spring clip assembly 8 includes a first clamping member 9 and a second clamping member 10. The first clamping member 9 and the second clamping member 10 can be formed by repeatedly bending a round bar. The end of the first clamping member 9 passes through the first connecting member 6, and the end of the second clamping member 10 passes through the second connecting member 7. The middle parts of the first clamping member 9 and the second clamping member 10 are hinged by a hinge member 11. When it is necessary to install the sheath, the operator can apply appropriate force to open the first clamping member 9 and the second clamping member 10, put the cable end 2 on, and then release the hand. The spring clip assembly 8 will automatically return to its clamping position under its own elastic restoring force, thereby quickly fixing the cable end 2.

[0034] Both the first clamping member 9 and the second clamping member 10 include a clamping arc 12. The clamping arc 12 passes through the first connecting member 6 or the second connecting member 7 to increase the contact area with the connecting member, thereby improving the stability of the connection. This allows the spring clamp assembly 8 to maintain a more stable fit with the connecting member when under force, reducing the risk of loosening or falling off. The clamping arc 12 is connected to a clamping rod 13. A hinge 11 is installed at the connection between the clamping arc 12 and the clamping rod 13. An auxiliary clamping member 14 is also connected to the end of the clamping rod 13. The auxiliary clamping member 14 facilitates the operator's gripping and operation of the first clamping member 9 and the second clamping member 10, further improving the convenience and efficiency of the sheath installation.

[0035] In this utility model, the insulating soft sheath, through its unique structure and high-quality material selection, effectively protects the cable ends 2 of different models. It is also reusable and easy to operate. In addition, when not in use, the insulating soft sheath is in a closed state, preventing dirt from entering, reducing maintenance costs, and improving the efficiency and safety of power maintenance and repair.
