Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more specifically, to a cable that is easy to install. Background Technology

[0002] A cable is made of one or more insulated conductors (usually copper or aluminum) and an outer insulating protective layer. It is used to transmit electricity or signals from one place to another. Simply put, it is like a "road" built for electricity or information, allowing them to reach their destination safely and efficiently.

[0003] Publication number "CN109524163A" describes "an easy-to-install cable, including an outer protective layer, a cutting marking layer on the outer protective layer, a threaded sleeve installed on the inner side of the outer protective layer, an inner protective layer installed on the inner side of the non-woven fabric layer, a first insulating layer installed on the inner side of the inner protective layer, a first insulating layer installed at the middle position of the inner side of the non-woven fabric layer, a thick conductor installed on the inner side of the first insulating layer, and a bidirectional connecting sleeve installed on the outer protective layer via the threaded sleeve, with threaded holes at both ends of the bidirectional connecting sleeve. The invention provides a cutting marking layer on the outer protective layer, and a threaded sleeve is installed on the inner side of the outer protective layer at the position of the cutting marking layer. A bidirectional connecting sleeve is provided in conjunction with the threaded sleeve, and threaded holes are provided at both ends of the bidirectional connecting sleeve. This design greatly facilitates the installation and disassembly of the cable and facilitates the connection between cables."

[0004] The aforementioned patent describes a cable with a cutting marking layer on its outer protective layer. A threaded sleeve is installed inside the outer protective layer, at the location of the cutting marking layer. A bidirectional connecting sleeve is fitted to the threaded sleeve, with threaded holes at both ends. This design greatly facilitates cable installation and disassembly, and makes cable connections easier. However, traditional cable connection methods typically involve terminal blocks or welding followed by insulation wrapping, a cumbersome and time-consuming process that demands high operator skill. In outdoor or complex environments, the problems of low connection efficiency and insufficient sealing are particularly prominent. Furthermore, existing quick-connect couplings often have complex structures and lack effective guidance during connection, easily leading to misalignment or damage of the wire cores, affecting connection reliability and service life. Therefore, we propose a cable that is easier to install. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] Example:

[0032] Please refer to Figure 1 - Figure 5 An easy-to-install cable, comprising:

[0033] Cable 1 at end A;

[0034] The insertion protrusion 8 is fixedly connected to the side end of the cable 1 at end A. The end side of the insertion protrusion 8 is provided with multiple core sleeve grooves 17.

[0035] A groove 10 is formed at the side end of cable 2 at end B. Multiple core connectors 18 are fixedly connected between the inner walls of the groove 10, and these core connectors 18 are inserted into multiple core sleeve slots 17.

[0036] The docking mechanism is located between cable 1 at end A and cable 2 at end B, and is used to guide multiple core connectors 18 and core sockets 17.

[0037] In this invention, the plug-in protrusion 8 is inserted into the groove 10, the inner circumferential wall of the multiple core sleeve grooves 17 is a copper metal ring, and the multiple core sleeve grooves 17 are connected to the conductors in the cable 1 at end A. The groove 10 is used to accommodate the plug-in protrusion 8, and the multiple core plugs 18 are inserted into the multiple core sleeve grooves 17. The multiple core plugs 18 and the copper metal rings in the multiple core sleeve grooves 17 are interference-fitted to achieve circuit connection. The docking mechanism is set between the cable 1 at end A and the cable 2 at end B, and is used to guide the multiple core plugs 18 and the core sleeve grooves 17.

[0038] The docking mechanism includes a sealing component, a plugging component, and a fixing component. The sealing component is located between cable 1 at end A and cable 2 at end B. The fixing component is located between cable 1 at end A and cable 2 at end B. The plugging component is located between cable 1 at end A and cable 2 at end B, and the plugging component is connected to the fixing component.

[0039] In this embodiment, the sealing component is used to prevent water from seeping in from the gap between cable 1 at end A and cable 2 at end B, the fixing component is used to ensure a tight connection between cable 1 at end A and cable 2 at end B, and the plugging mechanism is used to ensure that the multiple core plugs 18 are accurately aligned with the core sockets 17.

[0040] The sealing assembly includes a sealing groove 5 and a rubber ring 6. The sealing groove 5 is opened at the side end of the A-end cable 1, and the rubber ring 6 is embedded between the inner walls of the sealing groove 5. The sealing groove 5, the rubber ring 6, the A-end cable 1 and the B-end cable 2 are axially concentric.

[0041] In this embodiment, the sealing groove 5 is used to accommodate the rubber ring 6. The rubber ring 6 seals the gap between the end faces of the cable 1 at end A and the cable 2 at end B by deformation, preventing water vapor from seeping into the connection between the core sleeve groove 17 and the core connector 18 from the gap between the cable 1 at end A and the cable 2 at end B, thereby preventing water vapor from seeping into the cable joint and reducing the risk of short circuit due to water vapor seepage in the cable.

[0042] The fixing assembly includes an annular threaded block 3, a movable threaded sleeve 4, a limiting ring 11, an internal thread 15, and an external thread 16. The annular threaded block 3 is fixedly connected to the circumferential surface of the cable 1 at end A, the limiting ring 11 is fixedly connected to the circumferential surface of the cable 2 at end B, the movable threaded sleeve 4 is wrapped around the circumferential surface of the limiting ring 11, and the movable threaded sleeve 4 is fitted onto the circumferential surface of the cable 2 at end B. The external thread 16 is formed on the circumferential surface of the annular threaded block 3, and the inner circumferential wall of the movable threaded sleeve 4 is provided with an internal thread 15, and the internal thread 15 and the external thread 16 are threadedly connected.

[0043] In this embodiment, the annular threaded block 3 is used to support the guide ring 12, the limiting ring 11 is used to restrict the movable screw sleeve 4 from falling off the docking end of the cable 2 at end B, the movable screw sleeve 4 is used to support multiple guide blocks 14, the external thread 16 and the internal thread 15 are connected by threads, after multiple core connectors 18 are inserted into multiple core sleeve slots 17, the movable screw sleeve 4 is squeezed and pushed close to the annular threaded block 3, and the multiple guide blocks 14 enter between the external thread 16 and the guide ring 12 through multiple guide slots 13. At this time, the movable screw sleeve 4 is rotated so that the internal thread 15 and the external thread 16 are threadedly connected, thereby making the cable 1 at end A and the cable 2 at end B tightly connected.

[0044] The plug-in assembly includes a slot 7, a mating ring 9, a guide ring 12, a guide groove 13, and a guide block 14. The slot 7 is located on the end face of cable 1 at end A. The mating ring 9 is fixedly connected to the end face of cable 2 at end B, and the mating ring 9 and the groove 10 are axially concentric. The mating ring 9 is plugged into the slot 7. The guide ring 12 is fixedly connected to the circumferential surface of the annular threaded block 3. Multiple guide grooves 13 are provided, and multiple guide grooves 13 are located on the circumferential surface of the guide ring 12. Multiple guide blocks 14 are provided, and multiple guide blocks 14 are circumferentially distributed and fixedly connected between the inner circumferential walls of the movable threaded sleeve 4. The multiple guide blocks 14 correspond to the multiple guide grooves 13.

[0045] In this embodiment, the slot 7 is used to accommodate the insertion of the mating ring 9. The mating ring 9, through its insertion into the slot 7, causes the end faces of multiple wire core connectors 18 to mate with the end faces of the insertion protrusions 8, resulting in initial mating between the multiple wire core connectors 18 and the insertion protrusions 8. The guide ring 12 is used to prevent the multiple guide blocks 14 from approaching the external thread 16. Simultaneously, when the multiple guide blocks 14 are located between the guide ring 12 and the external thread 16, and when the multiple guide blocks 14 are not aligned with the multiple guide grooves 13, the guide ring 12 can also prevent the multiple guide blocks 14 from moving away. 3. The multiple guide blocks 14, multiple core socket grooves 17, and multiple core plugs 18 are in the same even number. The multiple guide grooves 13 are used to guide the multiple guide blocks 14 to approach the multiple external threads 16. At the same time, the multiple guide grooves 13 slide with the multiple guide blocks 14, so that the multiple core plugs 18 are accurately inserted into the multiple core socket grooves 17. This ensures that the multiple core plugs 18 and the core socket grooves 17 are accurately aligned, effectively preventing insertion difficulties or component damage caused by misalignment, and greatly improving the smoothness and reliability of cable splicing installation.

[0046] The limiting ring 11 is made of rubber, and the limiting ring 11 is interference-fitted with the movable screw sleeve 4.

[0047] In this embodiment, the limiting ring 11 is used to prevent moisture from entering the joint between the A-end cable 1 and the B-end cable 2 through the gap between the movable threaded sleeve 4 and the B-end cable 2. The rubber limiting ring 11 forms an interference fit with the inner wall of the annular threaded block 3, constituting a second seal. Together with the sealing groove 5 and the rubber ring 6, a first seal is formed, achieving a double seal at the joint between the A-end cable 1 and the B-end cable 2 conductors. Together, they form a multi-level sealing structure, which significantly improves the waterproof and dustproof performance of the cable connection and is suitable for various harsh environments.

[0048] The present invention provides a method for using a cable that is easy to install:

[0049] Bring the ends of cable 1 (end A) and cable 2 (end B) close together. First, align the multiple guide blocks 14 on the movable sleeve 4 with the multiple guide grooves 13 on the annular threaded block 3, and then push it forward. During this process, the mating ring 9 is inserted into the slot 7. At the same time, multiple core connectors 18 are accurately inserted into their corresponding core sleeve grooves 17 under the guidance structure. The multiple core connectors 18 and the copper metal rings in the multiple core sleeve grooves 17 are interference-fitted to achieve circuit conduction. Then, rotate the movable sleeve 4 to make its internal threads... 15 engages with the external thread 16 of the annular threaded block 3. As the thread tightens, the ends of cable 1 at end A and cable 2 at end B are pulled tight, and the rubber ring 6 is pressed in and fills the sealing groove 5. The rubber ring 6 deforms between cable 1 at end A and cable 2 at end B to form the first seal. At the same time, the rubber limiting ring 11 forms an interference fit with the inner wall of the annular threaded block 3 to form the second seal. When the movable sleeving 4 is tightened to the point that it cannot be rotated, the installation is completed, and the cable connection achieves a reliable electrical connection and mechanical seal.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
