Description

Technical Field

[0001] This utility model relates to the field of high-voltage power transmission technology, specifically a high-voltage cable accessory grounding wire. Background Technology

[0002] The grounding wire of a high-voltage cable accessory is a crucial safety component in a power transmission system. It ensures that any voltage fluctuations and current leaks caused by cable faults or external interference during power system operation can be effectively guided to the ground.

[0003] Traditional accessories that lack quick-connect functionality may require more complex steps and more time to install, which can lead to delays in time-sensitive situations. Furthermore, traditional connection methods may require more specialized skills and tools, increasing installation costs and the likelihood of errors.

[0004] Devices without easy locking mechanisms may be more difficult to maintain and repair, especially in situations requiring quick disconnection and reconnection. Furthermore, unstable connections can lead to overheating of cable joints or electrical failures, increasing the risk of accidents. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-5A high-voltage cable accessory for connecting a ground wire includes a main body 1, a mating mechanism, and a clamping mechanism. The mating mechanism includes an upper clamping block 2, a lower clamping block 3, a first spring 4, and a contact plate 5. The upper clamping block 2 and the lower clamping block 3 are separately connected. The first spring 4 is mounted on the lower clamping block 3, and its two ends are fixedly connected to the lower clamping block 3 and the contact plate 5, respectively. The contact plate 5 is slidably connected to the lower clamping block 3. The clamping mechanism includes a second spring 6, a sliding frame 7, a connecting plate 8, an insulating plate 9, a plug rod 10, and a positioning plate 11. The second spring 6 is mounted on the connecting plate 8, and its two ends are fixedly connected to the sliding frame 7, respectively. The sliding frame 7 is mounted on the bottom of the lower clamping block 3 and is separately connected to the lower clamping block 3. The insulating plate 9 is mounted on the bottom of the connecting plate 8 and is separately connected to the connecting plate 8. The plug rod 10 is mounted on the insulating plate 9 and is slidably connected to the insulating plate 9. The positioning plate 11 is separately connected to the plug rod 10 to facilitate fixing the insulating plate 9 and the connecting plate 8.

[0029] In this embodiment, the mating mechanism includes an upper clamping block 2, a lower clamping block 3, a first spring 4, and a contact plate 5. In use, the upper clamping block 2 is placed on the processed high-voltage cable, and then the lower clamping block 3 is picked up, so that the lower clamping block 3 is connected to the upper clamping block 2. After the contact plate 5 on the lower clamping block 3 contacts the high-voltage cable, the lower clamping block 3 is continuously pulled until the first spring 4 can no longer be compressed. At this time, the connecting plate 8 is placed at the bottom of the lower clamping block 3, and the through rod 12 on the upper clamping block 2 has passed through the lower clamping block 3 and entered the connecting plate 8.

[0030] In this embodiment, the clamping mechanism includes a second spring 6, a sliding frame 7, a connecting plate 8, an insulating plate 9, an insert rod 10, and a positioning plate 11. During use, pressing the sliding frame 7 stretches the second spring 6, causing the sliding frame 7 to contact the stop plate 20 at the center of the connecting plate 8. When the through rod 12 is fully inserted into the connecting plate 8, the second spring 6, installed in the placement groove 19 inside the connecting plate 8, pulls the sliding frame 7 to slide inside the connecting plate 8. Simultaneously, the limiting rod 18 on the sliding frame 7 slides in the limiting hole 17 in the connecting plate 8, and the clamping rod 21 on the sliding frame 7 inserts into the first clamping hole 13 in the through rod 12. At this time, the connecting plate 8 and the lower clamping block 3 are fixed together. When another part of the through rod 12 is exposed externally, at this time... After the insulating plate 9 is installed, the through rod 12 passes through the insulating plate 9. Then, the insertion rod 10 is inserted into the insulating plate 9, and the insertion rod 10 is connected to the second locking hole 14. Then, the positioning plate 11 is placed on the outside of the rubber insulating plate 9, and the protrusion 15 on the insertion rod 10 is aligned with the positioning hole 16 between the positioning plates 11. Since the protrusion 15 is fixed in the positioning hole 16, the cable is clamped. When installing the ground wire body 1, the connector 22 is placed on the connecting bolts on the upper clamping block 2 and the lower clamping block 3. The connecting bolts are in the connecting groove 23 of the connector 22, and a fixing nut 25 is installed on each bolt. The connector 22 is completely fixed to the upper clamping block 2 and the lower clamping block 3.

[0031] Example 2:

[0032] In summary, during use, first, secure the connection to the cable by placing the upper clamp 2 onto the prepared high-voltage cable. Then, lift the lower clamp 3 to connect it to the upper clamp 2. Once the contact plate 5 on the lower clamp 3 contacts the high-voltage cable, continuously pull the lower clamp 3 until the first spring 4 can no longer be compressed. At this point, place the connecting plate 8 at the bottom of the lower clamp 3. The through rod 12 on the upper clamp 2 has passed through the lower clamp 3 and entered the connecting plate 8. Then, begin securing the connecting components. Pressing the sliding frame 7 stretches the second spring 6, causing the sliding frame 7 to contact the stop plate 20 at the center of the connecting plate 8. When the through rod 12 is fully inserted into the connecting plate 8, the second spring 6, installed in the placement groove 19 inside the connecting plate 8, pulls the sliding frame 7 to slide inside the connecting plate 8. Simultaneously, the limiting rod 18 on the sliding frame 7 slides in the limiting hole 17 in the connecting plate 8, and the sliding frame... The clamping rod 21 on the 7 is inserted into the first clamping hole 13 in the through rod 12. At this time, the connecting plate 8 and the lower clamping block 3 are fixed. When the other part of the through rod 12 is exposed, the insulating plate 9 is installed. After the through rod 12 passes through the insulating plate 9, the insert rod 10 is inserted into the insulating plate 9 and the insert rod 10 is connected to the second clamping hole 14. Then, the positioning plate 11 is placed outside the rubber insulating plate 9, and the protrusion 15 on the insert rod 10 is aligned with the positioning hole 16 between the positioning plates 11. Since the protrusion 15 is fixed in the positioning hole 16, the cable is clamped. When installing the ground wire body 1, the connector 22 is placed on the connecting bolts on the upper clamping block 2 and the lower clamping block 3. The connecting bolts are in the connecting groove 23 of the connector 22, and a fixing nut 25 is installed on each bolt. At this time, the connector 22 is completely fixed with the upper clamping block 2 and the lower clamping block 3.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
