Description

Technical Field

[0001] This invention relates to the field of power distribution terminal technology, specifically to a power distribution terminal that is easy to wire. Background Technology

[0002] With the deepening of smart distribution network construction, distribution terminal units (such as DTUs and FTUs), as the core nodes of distribution automation systems, play a crucial role in power distribution, power flow control, and power quality monitoring. Currently, distribution terminals typically adopt a box-type structure, which is connected to external power cables through busbars to realize node access and topology construction of the distribution network.

[0003] In the actual construction and operation and maintenance of power distribution networks, the access efficiency of power distribution terminals directly affects the time cost of power outage operations. Due to the constraints of tight electrical safety distance requirements, the wiring area of ​​existing power distribution terminals is often extremely limited in space. When multi-circuit power distribution node reconstruction or fault repair is required, the large number of cables introduced into the narrow space can easily cause physical interference, making it difficult for construction personnel to accurately complete mechanical fixing.

[0004] To improve the wiring environment, current solutions often increase the overall size of the terminal equipment to gain operating space, or by adding multiple maintenance windows to the side of the casing. Additionally, some designs attempt to use modular terminal blocks to improve access speed. However, increasing the overall size of existing solutions not only significantly increases the hardware cost of distribution network upgrades but also lacks applicability in situations where installation space is limited, such as on poles and ring main units. Furthermore, traditional fixed wiring layouts fail to establish a physical link between "wiring operations" and "power distribution status," meaning that during maintenance without power interruption or with partial energization, operators still face the electrical risk of accidentally touching live busbars.

[0005] Therefore, there is an urgent need for a mechanized power distribution terminal solution that can both improve the access efficiency of power distribution nodes and ensure the physical safety of the operation and maintenance process. Summary of the Invention

[0006] The purpose of this invention is to provide a power distribution terminal that is easy to wire, in order to solve the technical problems in the prior art that increase the cost due to increasing the size of the equipment and the operating space, make it unsuitable for space-constrained scenarios, and make it difficult to ensure operation and maintenance safety and monitor the connection quality of traditional wiring structures.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A power distribution terminal that is easy to wire includes a power distribution cabinet body. A support frame is provided inside the power distribution cabinet body. A measurement and control module, an operation control module, and a communication module are fixedly installed on the support frame. Multiple rotating shafts are provided on the support frame. Each rotating shaft includes a fixing part and a connecting part. The fixing part is fixedly connected to the support frame. A vertical sleeve is provided inside the fixing part. The sleeve is fixedly connected to the fixing part. A terminal block is rotatably installed on the sleeve. The operation control module is fixedly installed on the terminal block. A locking hole is provided at the end of the terminal block away from the sleeve. A fixing bolt assembly adapted to the locking hole is provided on the side of the support frame away from the rotating shafts. The fixing bolt assembly and the locking hole are used to lock the terminal block to the support frame.

[0008] By setting a rotatable connection between the terminal block and the support frame, operators can loosen the fixing bolt assembly and pull the terminal block outward during wiring operations. The operation control module and wiring position, which were originally located in the narrow space inside the distribution cabinet, will move to a more open operating area at the front of the distribution cabinet as the terminal block rotates. Operators no longer need to put their hands into the narrow gaps in the cabinet to work, which facilitates the operation of cable threading, fixing and calibrating. This fundamentally avoids the problem of multiple cables intertwining and interfering with each other in a small space, greatly reducing the difficulty of wiring operations and shortening the time cost of on-site wiring operations.

[0009] Preferably, both the connecting part and the sleeve have wire-passing holes on their side walls, the wire-passing holes on the connecting part and the sleeve are connected, the connecting part and the sleeve are fixedly connected, and the wire-passing holes are located on the rear side of the connecting part.

[0010] By providing cable passage holes on both the connection part and the side wall of the sleeve, the main cables connecting various modules can be directly fed from the rear of the cabinet into the back of the terminal block and the operation control module through the cable passage holes. The main cables are neatly arranged inside the rotating frame and will not be exposed in the operating space to interfere with wiring operations. At the same time, it is conducive to maintaining a neat and concealed arrangement of the main cables, and will not be excessively bent with repeated rotation of the terminal block. This can effectively avoid the problem of insulation layer damage and wire core breakage caused by repeated twisting of the main cables, thereby improving the neatness of the internal wiring and the service life of the overall structure.

[0011] Preferably, the rotating shaft frame further includes a mounting part, which is fixedly connected to the fixing part and the connecting part. The mounting part is located on the rear side of the connecting part. A first copper sheet is provided on the mounting part. A support plate is provided behind the terminal block. A second copper sheet is provided at the end of the support plate away from the terminal block. Insulating elements are provided between the first copper sheet and the mounting part, and between the second copper sheet and the support plate. When the terminal block is locked to the support frame, the first copper sheet and the second copper sheet are in contact, and the contact length between the first copper sheet and the second copper sheet is 5mm≤L≤15mm. After the terminal block is rotated forward by more than 15°, the first copper sheet and the second copper sheet are disengaged.

[0012] By installing a No. 1 copper plate on the mounting section and a No. 2 copper plate on the rear side of the terminal block, the No. 1 and No. 2 copper plates stably adhere and conduct electricity after the terminal block is fully rotated and locked back to the working position, thereby connecting the operation control module to the main power distribution circuit. When the terminal block is pulled outward and rotated for wiring operations, the No. 1 and No. 2 copper plates will automatically disconnect, and the operation control module and the terminals on the terminal block will automatically lose power. This physically eliminates the risk of liveness during wiring operations, eliminating the need for operators to disconnect the power in advance and perform voltage testing. It is especially suitable for uninterrupted maintenance and partial circuit modification operations, significantly improving the operational safety of on-site maintenance.

[0013] Preferably, a reset spring is fixedly installed on the side wall of the connecting part. The reset spring is a pressure spring. The end of the reset spring away from the connecting part is in contact with the rear side wall of the terminal block. The reset spring is in a compressed state from the locked state to the open state to the maximum angle between the terminal block and the support frame.

[0014] By installing a reset spring on the side wall of the connection part, when the operator loosens the fixing bolt assembly, the terminal block will automatically pop out under the elastic force of the reset spring. The operator does not need to manually reach into the cabinet to pull the terminal block. After popping out, the terminal block will remain at an open angle that is easy to operate, further reducing the complexity of operation. At the same time, the reset spring continuously applies an outward pushing force to the terminal block, which can keep the angle of the terminal block stable in the open wiring state and prevent the terminal block from shaking during the wiring process and affecting the operation.

[0015] Preferably, the mounting part is provided with two No. 1 copper sheets, which are respectively located on the upper and lower sides of the mounting part. The end of the No. 1 copper sheet away from the mounting part is provided with a guide part. The guide parts of the two No. 1 copper sheets are combined into a trumpet shape. The side of the two No. 1 copper sheets extending outside the mounting part can be elastically deformed. The gap between the two No. 1 copper sheets is 3mm≤H≤6mm. The thickness of the No. 2 copper sheet is B, which is 0.5mm≤HB≤1mm.

[0016] By setting a guide at the end of the first copper plate furthest from the mounting part, the two first copper plates, combined with the guide to form a funnel-shaped opening, can automatically guide and correct the position of the second copper plate during the rotation of the terminal block back to its original position. Even if there is a slight positional deviation when the terminal block is pushed back, the second copper plate can smoothly slide into the space between the two first copper plates along the sloping surface of the funnel-shaped opening. This eliminates the need for operators to repeatedly adjust the position of the terminal block, significantly improving the convenience of terminal block repositioning and locking. Furthermore, since the gap between the two first copper plates is 0.5mm to 1mm smaller than the thickness of the second copper plate, after the second copper plate is inserted between the two first copper plates, the two first copper plates will tightly clamp the upper and lower sides of the second copper plate under their own elastic deformation. This ensures sufficient and uniform contact pressure between the first and second copper plates, preventing problems such as excessive contact resistance, overheating, and burning due to insufficient contact pressure after long-term operation, effectively improving the long-term stability of the main circuit connection.

[0017] Preferably, an insulating sleeve is fixedly connected to the mounting part. The insulating sleeve has a rectangular cross-section and is fitted over the two No. 1 copper sheets. The front end of the insulating contact is provided with a clearance groove that penetrates the inner and outer sides of the insulating sleeve. The clearance groove is used to allow the No. 2 copper sheet to enter the insulating sleeve.

[0018] By installing an insulating sleeve on the mounting section, which encloses the two No. 1 copper plates, allowing only the No. 2 copper plate to enter through the clearance slot, the No. 1 copper plates in other positions are completely isolated by the insulating sleeve. This effectively avoids the risk of electric shock caused by operators accidentally touching the No. 1 copper plate during wiring operations. Even when the No. 1 copper plate remains energized, the insulating sleeve completely isolates the energized conductor, further improving operational safety. Simultaneously, the insulating sleeve prevents dust and moisture from the cabinet from directly adhering to the surface of the No. 1 copper plate, reducing the rate of oxidation and corrosion and extending the service life of the conductive connection. Furthermore, the clearance slot located on the front side of the insulating sleeve prevents heat from being trapped during the connection of the No. 1 and No. 2 copper plates. It also allows the heat generated by inserting the No. 2 copper plate to quickly dissipate outwards through the slot, reducing the aging effects of high temperatures on the copper plates and insulation structure. At the same time, it does not obstruct the insertion of the No. 2 copper plate, ensuring smooth conductivity switching.

[0019] Preferably, the front end of the terminal block has multiple through holes that pass through both the front and rear sides of the terminal block, the multiple through holes are equidistantly arranged, and the through holes are arranged in two rows, one above the other.

[0020] By setting multiple rows of equidistant wire-passing holes at the front end of the terminal block, operators can directly pass cables of different circuits through the corresponding wire-passing holes from the front end when connecting external cables, and then crimp and fix the terminals. Compared with the traditional wiring method that requires winding the wires from the side and leaving slack, this wiring design allows the cables of each circuit to be arranged directly, and the direction of each cable is clear and independent, avoiding the problem of cable crossing and tangling. This facilitates quick identification of the corresponding circuit when checking the wiring and troubleshooting. Furthermore, the layout of the upper and lower rows can accommodate the wiring needs of more circuits within the limited area of ​​the terminal block without increasing the overall size of the terminal block. While ensuring sufficient operating space, it maintains the compact design of the distribution cabinet, adapting to the space requirements of ring main units, poles, and other confined installation scenarios.

[0021] Preferably, a magnetic block is fixedly installed on the side wall of the fixing part, and when the terminal block is rotated to the maximum angle, the rear side of the terminal block is in contact with the magnetic block.

[0022] By installing a magnetic block on the front side wall of the fixing part, when the terminal block is rotated to its maximum angle, the rear side of the terminal block will be attracted and fixed by the magnetic block, so that the terminal block can be stably kept in the open operation state and will not rotate and fall back on its own during the wiring process. The operator does not need to hold the terminal block to fix it, which frees up the hands to handle the wiring of multiple cables at the same time, further improving the efficiency of the wiring operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the structural design of a rotatable terminal block, allows the wiring operation area to be moved from the narrow space inside the cabinet to the open area on the front side of the cabinet. This fundamentally solves the problem of multiple circuit cables intertwining and interfering with each other in a small space. Operators do not need to put their hands into the gaps in the cabinet to work, which greatly reduces the difficulty of wiring operations and shortens the time cost of on-site operations. It is suitable for application scenarios with limited installation space, such as poles and ring main units, without increasing the overall size of the machine to gain operating space, thus reducing the hardware cost of power distribution network transformation.

[0024] 2. This invention utilizes the linkage on / off design of copper plates No. 1 and No. 2 to automatically disconnect the main circuit power supply when the terminal block is pulled out for wiring, and automatically reconnect after the wiring is completed and locked in place. This physically eliminates the risk of liveness during wiring operations, eliminating the need for operators to disconnect the power or test for voltage in advance. It is especially suitable for uninterrupted maintenance and partial circuit modification scenarios, significantly improving the operational safety of on-site maintenance. Combined with the insulating sleeve that encloses and isolates copper plate No. 1, it further avoids the risk of accidental contact with live parts, increasing the safety factor.

[0025] 3. This invention utilizes the cooperation of a reset spring and a magnetic block to automatically pop out the terminal block after the fixing bolt assembly is loosened. Once opened to its maximum angle, it automatically snaps into place, maintaining a stable operating angle. This eliminates the need for manual pulling or holding, freeing up the operator's hands and further improving the efficiency of wiring operations. The neatly arranged cable routing holes ensure clear and independent cable paths, facilitating subsequent cable inspection and further enhancing the convenience of wiring operations.

[0028] Please see Figures 1 to 8 This invention provides a power distribution terminal that is easy to wire, and the technical solution is as follows: For an easy-to-wire power distribution terminal, please refer to [link / reference]. Figures 1 to 2The system includes a power distribution cabinet body 1, a support frame 2 inside the power distribution cabinet body 1, and a measurement and control module 3, an operation control module 4, and a communication module 5 fixedly installed on the support frame 2. It should be noted that, in this embodiment, each set of operation control modules 4 is equipped with a set of measurement and control modules 3, and the measurement and control modules 3 are electrically connected to the operation control modules 4. The communication module 5 is located on the right side of the power distribution cabinet body 1, and the measurement and control modules 3 and the communication module 5 are electrically connected.

[0029] For further details, please refer to Figures 3 to 8 The support frame 2 is provided with multiple rotating shaft brackets 6. Each rotating shaft bracket 6 includes a fixing part 6a and a connecting part 6b. The fixing part 6a is fixedly connected to the support frame 2. A vertical sleeve 7 is provided inside the fixing part 6a. The sleeve 7 is fixedly connected to the fixing part 6a. A terminal block 8 is rotatably mounted on the sleeve 7. The operation control module 4 is fixedly mounted on the terminal block 8. A locking hole 8a is provided at the end of the terminal block 8 away from the sleeve 7. A fixing bolt that matches the locking hole 8a is provided on the side of the support frame 2 away from the rotating shaft bracket 6. Component 9, the fixing bolt assembly 9, and the locking hole 8a are used to lock the terminal block 8 to the support frame 2. Both the connecting part 6b and the sleeve 7 have wire-passing holes 6c on their side walls. The wire-passing holes 6c on the connecting part 6b and the sleeve 7 are interconnected, and the connecting part 6b and the sleeve 7 are fixedly connected. The wire-passing holes 6c are located on the rear side of the connecting part 6b. Multiple wire-passing holes 8b are provided at the front end of the terminal block 8, penetrating both the front and rear sides of the terminal block 8. These multiple wire-passing holes 8b are equidistantly arranged and arranged in two rows, one above the other. A reset spring 14 is fixedly installed on the side wall of the connecting part 6b. The reset spring 14 is a pressure spring, with the end of the reset spring 14 away from the connecting part 6b abutting against the rear side wall of the terminal block 8. From the locked state to the open state to the maximum angle, the reset spring 14 is under pressure. A magnetic block 16 is fixedly installed on the side wall of the fixing part 6a. When the terminal block 8 is rotated to its maximum angle, the rear side of the terminal block 8 abuts against the magnetic block 16. The rotating shaft frame 6 also includes a mounting part 6d, which is fixedly connected to the fixing part 6a and the connecting part 6b. The mounting part 6d is located behind the connecting part 6b. Two copper plates 10 are provided on the mounting part 6d. A support plate 11 is provided behind the terminal block 8. A copper plate 12 is provided at the end of the support plate 11 away from the terminal block 8. Insulating elements 13 are provided between the copper plate 10 and the mounting part 6d, and between the copper plate 12 and the support plate 11. When the terminal block 8 is locked to the support frame 2, the copper plate 10 and the copper plate 12 are in contact, and the contact length L between the copper plate 10 and the copper plate 12 is 6mm. In this embodiment, after the terminal block 8 rotates forward by more than 15°, the copper plate 10 and the copper plate 12 disengage.

[0030] For further details, please refer to Figure 6Two copper sheets 10 are respectively disposed on the upper and lower sides of the mounting part 6d. The end of the copper sheet 10 away from the mounting part 6d is provided with a guide part 10a. The guide parts 10a of the two copper sheets 10 are combined to form a trumpet shape. The two copper sheets 10 can be elastically deformed on the side extending outside the mounting part 6d. The gap between the two copper sheets 10 is H=4mm. The thickness of the copper sheet 12 is B=4.5mm. For further details, please refer to Figure 5 and Figure 7 An insulating sleeve 15 is fixedly connected to the mounting part 6d. The insulating sleeve 15 has a rectangular cross-section and is fitted over the two No. 1 copper pieces 10. The front end of the insulating contact is provided with a clearance slot 15a, which penetrates the inner and outer sides of the insulating sleeve 15. The clearance slot 15a is used to allow the No. 2 copper piece 12 to enter the insulating sleeve 15.

[0031] Working principle: Please refer to Figures 1 to 8When wiring or maintenance work is required on this power distribution terminal, the operator first loosens the fixing bolt assembly 9 to release the lock between the terminal block 8 and the support frame 2. Under the continuous elastic force of the reset spring 14 on the side wall of the connection part 6b, the terminal block 8 will automatically rotate outward around the sleeve 7 and pop out. When the terminal block 8 rotates to the maximum opening angle, the rear side wall of the terminal block 8 will adhere to the magnetic block 16 on the side wall of the fixing part 6a. The magnetic force of the magnetic block 16 will stably keep the terminal block 8 in the open operating angle. At this time, the first copper piece 10 and the second copper piece 12 have been completely separated, and all terminals on the operation control module 4 and the terminal block 8 have been physically disconnected from the main circuit power supply. The operator can directly perform wiring work in the open space in front of the power distribution cabinet body 1 without having to put their hands into the narrow gaps inside the cabinet. When wiring, only Insert the external cables of different circuits into the corresponding through holes 8b at the front end of the terminal block 8, and then crimp the cable ends to the corresponding terminals to fix them. The cables of each circuit are independently and neatly routed, and there will be no problem of crossing or tangling. After the wiring is completed, the operator only needs to push the terminal block 8 inward. The terminal block 8 rotates back to its original position around the sleeve 7. The second copper piece 12 will slide into the space between the two first copper pieces 10 along the flared guide 10a at the front end of the two first copper pieces 10. Even if there is a slight positional deviation during the pushing process, the guide slope can automatically correct the position of the second copper piece 12 and successfully complete the alignment and insertion. When the terminal block 8 is rotated to the locked position, screw the fixing bolt assembly 9 into the locking hole 8a to complete the locking. At this time, the first copper piece 10 and the second copper piece 12 are stably attached and conductive. The operation control module 4 automatically connects to the main circuit, and the entire wiring operation is completed. During wiring operations, the first copper sheet 10 is always enclosed and sealed by the insulating sleeve 15, with only the slot 15a allowing the second copper sheet 12 to enter and exit. This eliminates the risk of operators accidentally touching the live first copper sheet 10, ensuring operator safety even during uninterrupted power supply operations. During long-term operation, the two first copper sheets 10 continuously clamp the second copper sheet 12 using their own elasticity, maintaining stable and uniform contact pressure and preventing excessive contact resistance, overheating, and burning. The insulating sleeve 15 also prevents dust and moisture from corroding the first copper sheet 10, extending the service life of the conductive connection part 6b. The wire passage holes 6c are uniformly located behind the connection part 6b and the sleeve 7, ensuring neat internal wiring that avoids repeated bending as the terminal block 8 rotates, fundamentally preventing internal core wire breakage and improving the overall structure's service life.

[0032] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
