Description

Technical Field

[0001] This utility model relates to the field of ring main unit terminal block technology, specifically to a flip-type ring main unit cable terminal block. Background Technology

[0002] In urban power grids and industrial power distribution systems, ring main units (RNBs) are widely used for cable line branching, interconnection, and fault isolation due to their compact structure, small footprint, and flexible operation. Cable terminals, as the core component connecting the RNB to external cables, play a crucial role in ensuring stable power transmission and reliable electrical connections. Their performance directly affects the safety, stability, and operational efficiency of the entire power supply system.

[0003] However, the current terminal block installation direction is fixed, and it needs to be disassembled and reassembled when the cable access direction needs to be changed, which is inefficient and affects actual use. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a flip-type ring main unit cable terminal.

[0005] The specific technical solution is as follows:

[0006] A reversible ring main unit cable terminal block includes: a limiting component and a ring main unit body. A first fixing plate and a second fixing plate are detachably installed on one side of the inner wall of the ring main unit body. A first groove is provided on one side of the surface of the first fixing plate and the second fixing plate. A mounting bolt is inserted into the first groove so that the first fixing plate and the second fixing plate can be fixed to one side of the inner wall of the ring main unit body by the mounting bolt. A limiting component is provided on one side of the middle section of the first fixing plate. A terminal block body is detachably installed between the first fixing plate and the second fixing plate.

[0007] As a preferred embodiment of this utility model, the first fixing plate and the second fixing plate are respectively provided with through holes on one side, a rotating shaft is rotatably installed in the through hole, and the other end of the rotating shaft is rotatably connected to a connecting plate through a bearing. A connecting block is fixedly installed on one side of the connecting plate, and a screw block is fixedly connected to the other side of the rotating shaft located in the through hole of the first fixing plate.

[0008] As a preferred embodiment of this utility model, the connecting block is provided with a snap-fit ​​groove on one side, and the two sides of the terminal body are attached with snap-fit ​​blocks by structural adhesive. The snap-fit ​​blocks and the connecting block are provided with the same threaded hole on one side of the snap-fit ​​groove, and the threaded hole is threaded with a connecting bolt.

[0009] As a preferred embodiment of this utility model, the limiting component includes a lead screw and a threaded sleeve limiting frame plate. The threaded sleeve is fixedly installed on one side of the middle section of the first fixed plate, the lead screw is threadedly installed inside the threaded sleeve, and a turntable is fixedly installed on one side of the lead screw.

[0010] As a preferred embodiment of this utility model, the other side of the lead screw is rotatably connected to a rotating shaft, one side of the rotating shaft is rotatably connected to a second groove provided on one side of the limiting frame plate, and one side of the limiting frame plate is fixedly connected to a guide rod, the other end of the guide rod passing through one side of the first fixed plate.

[0011] As a preferred embodiment of this utility model, silicone blocks are adhered to both sides of the inner wall of the limiting frame plate. By rotating the turntable to drive the lead screw to move axially, the limiting frame plate is pushed towards the terminal body to achieve limiting.

[0012] This utility model has the following beneficial effects:

[0013] 1. The flip-type ring main unit cable terminal block provided by this utility model, through the design of a first fixing plate, a second fixing plate, and a limiting component, allows for pre-fixing of the first and second fixing plates to one side of the inner wall of the ring main unit during use. After adjusting the installation spacing, the terminal block body is then secured by the snap-fit ​​blocks bonded to both sides of the terminal block body and the connecting blocks on the first and second fixing plates, and then locked with connecting bolts. This completes the fixing of the terminal block body. The limiting component at one end of the first fixing plate further secures the terminal block, preventing frequent rotation due to lack of limiting. When it is necessary to flip the terminal block body, the limiting component is removed to release the limiting. The operator can then manually rotate the terminal block body or rotate the screw block to drive the rotating shaft, causing the connecting blocks on one side to rotate and flip together. During the flipping process, the terminal block body also flips, completing the flipping of the terminal block body. This allows for flexible adaptation to multi-directional cable access without disassembly and improves maintenance convenience.

[0014] 2. The flip-type ring main unit cable terminal provided by this utility model, through the design of lead screw, threaded sleeve and limiting frame plate, after the terminal body is flipped, the lead screw is rotated by rotating the turntable, so that the lead screw moves axially in the threaded sleeve. During the movement, the limiting frame plate is pushed to approach the terminal body along the guide rod. Then the two sides of the limiting frame plate are attached to the two sides of the terminal body. The silicone blocks on both sides of the inner wall of the limiting frame plate elastically press the two sides of the terminal, improving the limiting stability. When it is necessary to flip and adjust the connection port of the terminal body in the future, the limiting can be easily released or re-limited. Attached Figure Description

[0032] The reversible ring main unit cable terminal block provided in this embodiment, such as... Figures 1-7As shown, the system includes: a limiting component 4 and a ring main unit 1. A first fixing plate 3 and a second fixing plate 5 are detachably installed on one side of the inner wall of the ring main unit 1. A first groove is provided on one side of the surface of both the first fixing plate 3 and the second fixing plate 5. A mounting bolt 301 is inserted into the first groove so that the first fixing plate 3 and the second fixing plate 5 can be fixed to one side of the inner wall of the ring main unit 1 by the mounting bolt 301. A limiting component 4 is provided on one side of the middle section of the first fixing plate 3. A terminal block body 2 is detachably installed between the first fixing plate 3 and the second fixing plate 5. A through hole is provided on one side of the first fixing plate 3 and the second fixing plate 5. A rotating shaft 305 is rotatably installed in the through hole. The other end of the rotating shaft 305 is rotatably connected to a connecting plate 304 through a bearing. A connecting block 302 is fixedly installed on one side of the connecting plate 304, and a screw block 306 is fixedly connected to the other side of the rotating shaft 305 located in the through hole of the first fixing plate 3. The fastening block 302 has a snap-fit ​​groove on one side, and the terminal block body 2 has snap-fit ​​blocks 201 glued to both sides by structural adhesive. Both the snap-fit ​​blocks 201 and the fastening block 302 have the same threaded holes on one side of the snap-fit ​​groove, and the threaded holes are connected to the fastening bolts 303.

[0033] Through the design of the first fixing plate 3, the second fixing plate 5, and the limiting component 4, in use, the first fixing plate 3 and the second fixing plate 5 are fixed to one side of the inner wall of the ring network cabinet 1 beforehand, and the installation spacing is adjusted. Then, the snap-fit ​​blocks 201 bonded to both sides of the terminal body 2 are snapped into the connecting blocks 302 on the first fixing plate 3 and the second fixing plate 5, and then locked with the connecting bolts 303 to complete the fixing of the terminal body 2. Then, the limiting component 4 provided at one end of the first fixing plate 3 is used to fix it, avoiding the problem of frequent rotation due to lack of limiting of the terminal body 2. When it is necessary to flip the terminal body 2, the limiting component 4 is removed to release the limiting. The operator can rotate the terminal body 2 by hand or rotate the screw block 306 to make the rotating shaft 305 drive the connecting plate 304 to make the connecting block 302 installed on one side rotate and flip together. During the flipping process, the terminal body 2 is flipped together, thus completing the flipping of the terminal body 2. This allows for flexible adaptation to multi-directional cable access without disassembly and improves maintenance convenience. Example

[0034] The reversible ring main unit cable terminal block provided in this embodiment, such as... Figures 4-7As shown, the device includes: a limiting assembly 4 comprising a lead screw 401, a threaded sleeve 403, and a limiting frame 404. The threaded sleeve 403 is fixedly installed on one side of the middle section of the first fixed plate 3. The lead screw 401 is threadedly installed inside the threaded sleeve 403. A turntable 402 is fixedly installed on one side of the lead screw 401. A rotating shaft 406 is rotatably connected to the other side of the lead screw 401. One side of the rotating shaft 406 is rotatably connected to a second groove provided on one side of the limiting frame 404. A guide rod 407 is fixedly connected to one side of the limiting frame 404, and the other end of the guide rod 407 passes through one side of the first fixed plate 3. Silicone blocks 405 are adhered to both sides of the inner wall of the limiting frame 404. By rotating the turntable 402, the lead screw 401 is driven to move axially, thereby pushing the limiting frame 404 towards the terminal body 2 to achieve limiting.

[0035] Through the design of the lead screw 401, threaded sleeve 403, and limiting frame plate 404, after the terminal body 2 is flipped, the lead screw 401 is rotated by rotating the turntable 402, causing the lead screw 401 to move axially within the threaded sleeve 403. During the movement, the limiting frame plate 404 is pushed to approach the terminal body 2 along the guide rod 407. Then, the two sides of the limiting frame plate 404 are attached to the two sides of the terminal body 2. The silicone blocks 405 on both sides of the inner wall of the limiting frame plate 404 elastically press the two sides of the terminal, improving the stability of the limiting. When it is necessary to flip and adjust the connection port of the terminal body 2 in the future, the limiting can be easily released or re-limited.

[0036] In summary, the flip-type ring main unit cable terminal block provided in this embodiment has the following advantages: it flexibly adapts to multi-directional cable access, facilitates quick disassembly and reversal for maintenance, and improves its practical usability.

[0037] In use, the first fixing plate 3 and the second fixing plate 5 are first fixed to one side of the inner wall of the ring main unit 1, and the installation spacing is adjusted. Then, the snap-fit ​​blocks 201 bonded to both sides of the terminal body 2 are snapped into the connecting blocks 302 on the first fixing plate 3 and the second fixing plate 5, and then locked with the connecting bolts 303 to complete the fixing of the terminal body 2. Then, by rotating the turntable 402, the lead screw 401 is rotated together, so that the lead screw 401 moves axially within the threaded sleeve 403. During the movement, the limiting frame plate 404 is pushed to move closer to the guide rod 407 in a straight line. The terminal block body 2 is then attached to both sides of the limiting frame plate 404. The silicone blocks 405 on both sides of the inner wall of the limiting frame plate 404 elastically press the two sides of the terminal block. Then, the limiting is released by rotating in the opposite direction. The operator can rotate the terminal block body 2 by hand or rotate the screw block 306 to make the rotating shaft 305 drive the connecting plate 304 to make the connecting block 302 installed on one side rotate and flip together. During the flipping process, the terminal block body 2 is also flipped together, thus completing the flipping of the terminal block body 2. This allows for flexible adaptation to multi-directional cable access and completes the flipping of the terminal block 2.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
