Description

Technical Field

[0001] This utility model relates to the field of cable splicing technology, and in particular to a splicing high-temperature cable. Background Technology

[0002] Existing splicing high-temperature cables achieve their clamping and fixing effect by rotating a threaded cylinder to push pressure blocks against the cables, allowing two cables to be spliced ​​together. However, the connection area is small, resulting in a small distance between the two sets of pressure blocks, which easily leads to stress concentration at the connection point. For example, a splicable wire and cable disclosed in Chinese Patent Application No. CN202420590593.0, although equipped with a connecting component and connecting post, uses two clamping plates in the connecting component to clamp and connect the two ends of the two wire cores. Then, by rotating the threaded cylinder, the limiting sleeve is controlled to one side, which in turn squeezes the two pressure blocks to the opposite side, thus firmly clamping and fixing the cables and achieving rapid splicing of two cables. However, the limiting sleeve is short, which makes it easy for large stress to accumulate at the limiting sleeve during use, resulting in damage to the connecting components, increasing the failure rate, and limiting its use. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a splicing high-temperature cable. By inserting the cores of two sets of cables into the connecting block inside the insulating sleeve, the two sets of cores are connected together through the connecting block. The fixing cylinder is fixed to the outer layer of the cable with a clamping block. Then, the threaded cylinders on both sides are pulled, and the connecting sleeve is fixed to the insulating sleeve from both ends by a threaded connection, thereby realizing the connection of the two sets of cables. A spring connected to the extension cylinder is provided in the fixing cylinder to increase the movement distance of the extension cylinder and increase the fault tolerance. After the threaded cylinder is fixed on the connecting sleeve, the elastic force of the spring is used to pull the connecting sleeve on both sides of the threaded cylinder respectively, thereby enhancing the fixing effect between the connecting sleeve and the threaded cylinder.

[0004] This utility model also provides a high-temperature cable with the above-mentioned splicing type, including: a cable outer layer, a filling layer fixedly connected to the inner side wall of the cable outer layer, a protective layer fixedly connected to the inner side wall of the filling layer, and a battery cell fixedly connected to the inner side wall of the protective layer.

[0005] A connecting sleeve is fixedly connected to the side surface of the outer layer of the cable. An insulating sleeve is fixedly connected to the inner side wall of the connecting sleeve. A connecting block is fixedly connected to the inner side wall of the insulating sleeve. A threaded block is fixedly connected to the side surface of the connecting sleeve. A threaded cylinder is threadedly connected to the side surface of the threaded block. A connecting ring is rotatably connected to the side surface of the threaded cylinder. An extension cylinder is fixedly connected to the side surface of the connecting ring. A fixed cylinder is slidably connected to the side surface of the extension cylinder. Using these components, the fixed cylinder can be fixed to the outer layer of the cable, and the threaded cylinder can be used to fix the connecting sleeve from both sides, allowing the connecting sleeve to be fixed at the connection point of the two sets of cables. The connecting block inside the connecting sleeve connects the battery cells, ensuring the transmission of electrical energy and signals.

[0006] According to the present invention, a splicing high-temperature cable has a locking block fixedly connected to the side surface of the fixing cylinder, and the outer layer of the cable is located between the fixing cylinder and the locking block. The locking block is fixed to the fixing cylinder, so that the fixing cylinder can be fixed on the limiting outer layer.

[0007] According to the splicing high-temperature cable of this utility model, a bolt is fixedly connected to the side surface of the clamping block, and a nut is threadedly connected to the side surface of the bolt. The clamping block and the fixing cylinder are fixed together by the bolt and the nut.

[0008] According to the splicing high-temperature cable of this utility model, a spring is fixedly connected to the end of the extension tube away from the connecting ring, and the end of the spring away from the extension tube is fixedly connected to the fixed tube. The spring pulls the extension tube, enhancing the fixing effect of the threaded tubes at both ends on the connecting sleeve.

[0009] According to the splicing high-temperature cable of this utility model, a limiting plate is fixedly connected to the side surface of the extension tube, and the side surface of the limiting plate is slidably connected to the fixed tube. This enhances the stability of the extension tube's sliding motion.

[0010] According to the splicing high-temperature cable of this utility model, a limiting ring is fixedly connected to one end of the threaded cylinder near the connecting ring, and the side surface of the limiting ring is rotatably connected to the connecting ring. This ensures that the threaded cylinder does not detach from the connecting ring when it rotates.

[0011] According to the splicing high-temperature cable of this utility model, the inner side of the extension tube is slidably connected to the outer layer of the cable, and the inner side of the connecting ring is also slidably connected to the outer layer of the cable. When the threaded tube is fixed to the connecting sleeve, the extension tube will slide along the outer layer of the cable along with the connecting ring.

[0012] According to the present invention, in a splicing high-temperature cable, the inner wall of the connecting block is fixedly connected to the battery core during operation, and the inner side of the fixing cylinder is fixedly connected to the outer layer of the cable. The cables at both ends of the connecting sleeve can be connected together by inserting the battery core into the connecting block.

[0013] Beneficial effects:

[0014] Compared with existing technologies, this method connects the two sets of cables by inserting the cores of the two sets of cables into the connecting block inside the insulating sleeve. The fixing cylinder is then fixed to the outer layer of the cable by a locking block. The threaded cylinders on both sides are pulled to fix the connecting sleeve to the insulating sleeve from both ends using a threaded connection, thus connecting the two sets of cables. A spring connected to the extension cylinder is provided in the fixing cylinder to increase the movement distance of the extension cylinder and increase the fault tolerance. After the threaded cylinder is fixed on the connecting sleeve, the elasticity of the spring is used to pull the connecting sleeve on both sides of the threaded cylinder, thereby enhancing the fixing effect between the connecting sleeve and the threaded cylinder.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model embodiment provides a spliced ​​high-temperature cable, which includes: a cable outer layer 1, a filling layer 2 fixedly connected to the inner side wall of the cable outer layer 1, a protective layer 3 fixedly connected to the inner side wall of the filling layer 2, and a battery cell 4 fixedly connected to the inner side wall of the protective layer 3.

[0024] Specifically, the outer layer 1 of the cable is used to protect the inner protective layer 3 and the battery core 4 of the cable. The filling layer 2 is filled inside the outer layer 1 of the cable to wrap the protective layer 3. The battery core 4 is located inside the protective layer 3. When wiring is required, a portion of the outer layer 1, filling layer 2 and protective layer 3 of the cable can be cut off to expose the battery core 4.

[0025] A connecting sleeve 12 is fixedly connected to the side surface of the outer layer 1 of the cable. An insulating sleeve 14 is fixedly connected to the inner side wall of the connecting sleeve 12. A connecting block 15 is fixedly connected to the inner side wall of the insulating sleeve 14. The inner side wall of the connecting block 15 is fixedly connected to the battery core 4 during operation. A threaded block 17 is fixedly connected to the side surface of the connecting sleeve 12. A threaded cylinder 11 is threadedly connected to the side surface of the threaded block 17. A connecting ring 10 is rotatably connected to the side surface of the threaded cylinder 11. The inner side of the connecting ring 10 is slidably connected to the outer layer 1 of the cable. An extension cylinder 8 is fixedly connected to the side surface of the connecting ring 10. The inner side of the extension cylinder 8 is slidably connected to the outer layer 1 of the cable. A fixed cylinder 7 is slidably connected to the side surface of the extension cylinder 8. The inner side of the fixed cylinder 7 is fixedly connected to the outer layer 1 of the cable. A locking block 5 is fixedly connected to the side surface of the fixed cylinder 7. The outer layer 1 of the cable is located between the fixed cylinder 7 and the locking block 5. A bolt 6 is fixedly connected to the side surface of the locking block 5. A nut 18 is threadedly connected to the side surface of the bolt 6.

[0026] Specifically, when starting the wiring, first use the fixing sleeve 7 to put on the outer layer 1 of the cable, and then use bolts 6 and nuts 18 to fix the clamping block 5 to the fixing sleeve 7 so that the fixing sleeve 7 can be fixed on the outer layer 1 of the cable. Then, insert the exposed battery core 4 into the connecting block 15 located in the insulating sleeve 14. The connecting block 15 is made of conductive material so that the battery cores 4 of the two sets of cables can be connected through the connecting block 15. Then insert a part of the outer layer 1 of the cable into the connecting sleeve 12. Then pull the threaded sleeve 11 and fix the threaded sleeve 11 on the threaded block 17 connected to the connecting sleeve 12. During the fixing process, the threaded sleeve 11 will pull the connecting ring 10 and the extension sleeve 8 through the limiting ring 16 and will stretch the spring 13. At the same time, under the action of the limiting ring 16, the threaded sleeve 11 will rotate relative to the connecting ring 10 and will not cause the threaded sleeve 11 to detach from the connecting ring 10.

[0027] A spring 13 is fixedly connected to the end of the extension cylinder 8 away from the connecting ring 10. The end of the spring 13 away from the extension cylinder 8 is fixedly connected to the fixed cylinder 7. A limit plate 9 is fixedly connected to the side surface of the extension cylinder 8. The side surface of the limit plate 9 is slidably connected to the fixed cylinder 7. A limit ring 16 is fixedly connected to the end of the threaded cylinder 11 near the connecting ring 10. The side surface of the limit ring 16 is rotatably connected to the connecting ring 10.

[0028] Specifically, by using spring 13 to connect the extension cylinder 8 and the fixed cylinder 7, the extension cylinder 8 will not detach from the connection with the fixed cylinder 7 after it moves. After the threaded cylinder 11 is connected to the connecting sleeve 12, the springs 13 on both sides will pull the threaded cylinder 11 respectively, which improves the fixing effect between the connecting sleeve 12 and the threaded cylinders 11 on both sides. The extension cylinder 8 is provided with a limiting plate 9. When the extension cylinder 8 moves, the limiting plate 9 will restrict the movement direction of the extension cylinder 8, so that the extension cylinder 8 can only move along the direction of the limiting plate 9, which improves the stability of the movement of the extension cylinder 8. One end of the threaded cylinder 11 is connected to a limiting ring 16, so that the threaded cylinder 11 can rotate relative to the connecting ring 10, and the threaded cylinder 11 will not detach from the connecting ring 10.

[0029] Working principle: Before connection, a portion of the outer layer 1, filling layer 2, and protective layer 3 of the cable are cut off to expose the battery core 4. Then, a fixing cylinder 7 is placed on the outer layer 1 of the cable, and the clamping block 5 is fixed to the fixing cylinder 7 by bolts 6 and nuts 18, so that the fixing cylinder 7 can be fixed on the outer layer 1 of the cable. Then, the exposed battery core 4 is inserted into the connecting block 15 located in the insulating sleeve 14, and a portion of the outer layer 1 of the cable is inserted into the connecting sleeve 12. Then, the threaded cylinder 11 is pulled and fixed on the threaded block 17 connected to the connecting sleeve 12. During the fixing process, the threaded cylinder 11 will pull the connecting ring 10 and the extension cylinder 8 through the limiting ring 16, and will stretch the spring 13. At the same time, under the action of the limiting ring 16, the threaded cylinder 11 will rotate relative to the connecting ring 10 without causing the threaded cylinder 11 to detach from the connecting ring 10. Then, the above steps are repeated to insert the battery core 4 of the other set of cables into the connecting block 15, thereby realizing the splicing of the two sets of cables.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
