Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a quick wiring device for a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] With the global energy structure transformation and the rapid development of smart grid technology, the requirements for power system operating efficiency, power supply reliability and intelligence level are increasing. As a core device in the 10kV distribution network, the integrated primary and secondary pole-mounted circuit breaker plays a key role in line disconnection, control protection, status monitoring and fault isolation due to its advantage of deeply integrating primary switching equipment and secondary control and protection equipment. It has been widely used in urban distribution network upgrading and transformation, rural revitalization power supply guarantee and new power system construction.

[0003] The prior art patent document CN222995297U discloses a quick-connection device for a primary and secondary integrated pole-mounted circuit breaker, comprising a base plate, a second clamping plate fixed on the base plate, and a first clamping plate directly above the second clamping plate. The first clamping plate is larger than the second clamping plate. A compression spring connects the four corners of the bottom surface of the first clamping plate to the base plate. A push rod is symmetrically arranged on both sides of the second clamping plate, and a groove for placing a cable connector is provided in the center of the top surface of the second clamping plate. In this invention, pressing down the push rods on both sides simultaneously causes the push rods to rotate around the pivot joint. The push rods drive a lifting block to rotate upwards, lifting the first clamping plate and inserting the cable connector into the gap between the first and second clamping plates, placing the cable connector at the bottom of the groove and in contact with the connector plate. After placement, releasing the push rods causes the first clamping plate to press the cable connector tightly under the pull of the compression spring, thus completing the quick connection between the cable connector and the connector plate.

[0004] The previous quick-connection device for the primary and secondary integrated pole-mounted circuit breaker had many shortcomings. It lacked a reliable locking structure. After adjustment, the position of the clamp was easily shifted due to external vibration, cable weight, or operational contact. Pressing and fixing with a single spring could easily cause thinner cables to loosen and slip, while thicker cables could be excessively squeezed, which not only affected the clamping stability but also created safety hazards for subsequent wiring operations. Utility Model Content

[0005] The purpose of this invention is to provide a quick wiring device for a primary and secondary integrated pole-mounted circuit breaker, which solves the problem of lacking a reliable locking structure.

[0006] To achieve the above objectives, this utility model provides a quick wiring device for a primary and secondary integrated pole-mounted circuit breaker, including a base plate. A support plate is fixedly connected to the top of the base plate. There are two support plates, and a connecting column is rotatably connected between the two support plates. An adjustment assembly is provided on the outer side of the connecting column. The adjustment assembly includes a connecting rod. A connecting block is rotatably connected to the inner side of the connecting rod. Multiple insertion holes are opened on the side of the connecting block. A pin is movably inserted through the interior of the connecting rod and inserted into the insertion hole. A stop block is fixedly connected to the side of the pin block. A first spring is fixedly connected between the side of the stop block and the outer side of the connecting rod. The first spring is sleeved on the outer side of the pin block. A handle is fixedly connected to the outer side of the stop block.

[0007] The connecting block is fixedly connected to an upper clamping plate on its outer side, and a second spring is fixedly connected to the bottom left end of the upper clamping plate. The bottom of the second spring is fixedly connected to the top of the base plate.

[0008] The bottom plate is fixedly connected to a lower clamping plate. The top of the lower clamping plate has a groove. A wiring plate is provided on one side of the lower clamping plate. The wiring plate passes through the lower clamping plate. The bottom surface of the groove is the upper surface of the wiring plate.

[0009] The lower clamp plate has an arc-shaped groove on the side opposite to the wiring plate, and the arc-shaped groove communicates with the groove.

[0010] The inner side of the arc-shaped groove is provided with the cable body.

[0011] The base plate is provided with a power assembly at its top. The power assembly includes a mounting plate, which is fixedly connected to the top of the base plate. There are two mounting plates in total, and a gear is rotatably connected between the two mounting plates.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a quick wiring device for a primary and secondary integrated pole-mounted circuit breaker, including a base plate 1, a support plate 2 fixedly connected to the top of the base plate 1, two support plates 2 in total, a connecting post 3 rotatably connected between the two support plates 2, an adjustment component 7 provided on the outer side of the connecting post 3, the adjustment component 7 including a connecting rod 77, a connecting block 71 rotatably connected to the inner side of the connecting rod 77, multiple insertion holes 72 opened on the side of the connecting block 71, a pin 73 movably passing through the inside of the connecting rod 77, the pin 73 being inserted into the inside of the insertion hole 72, a stop block 75 fixedly connected to the side of the pin 73, and the stop block 75... A first spring 74 is fixedly connected between the side of the 5 and the outer side of the connecting rod 77. The first spring 74 is sleeved on the outer side of the pin 73. A handle 76 is fixedly connected to the outer side of the stop block 75. An upper clamping plate 6 is fixedly connected to the outer side of the connecting block 71. A second spring 10 is fixedly connected to the bottom left end of the upper clamping plate 6. The bottom of the second spring 10 is fixedly connected to the top of the base plate 1. A lower clamping plate 11 is fixedly connected to the top of the base plate 1. A groove 12 is formed at the top of the lower clamping plate 11. A wiring plate 4 is provided on one side of the lower clamping plate 11, penetrating through the lower clamping plate 11. The bottom surface of the groove 12 is the upper surface of the wiring plate 4. In practical applications, when facing cable bodies 9 of different diameters and specifications, it is necessary to adjust the distance between the upper clamping plate 6 and the lower clamping plate 11 to achieve stable and appropriate clamping of the cable body 9. The operator applies external force to pull the handle 76. The handle 76 is fixedly connected to the stop block 75. During the pulling of the handle 76, the stop block 75 moves accordingly. Since the pin 73 is fixedly connected to the stop block 75, the movement of the stop block 75 causes the pin 73 to move along the channel inside the connecting rod 77. The pin 73 gradually overcomes the elastic force of the first spring 74 and is pulled out from the multiple holes 72 pre-drilled on the side of the connecting block 71. At this time, the locking effect of the pin 73 on the connecting block 71 disappears, and the connecting rod 77 can rotate freely around the rotational connection point with the connecting block 71. Because the connecting rod 77 is indirectly connected to the upper clamping plate 6 through the connecting block 71, the rotation of the connecting rod 77 causes the upper clamping plate 6 to rotate around the connecting post 3, thereby changing the distance between the upper clamping plate 6 and the lower clamping plate 11. After the operator adjusts the upper clamp 6 to the appropriate position according to the actual specifications of the cable body 9, and releases the handle 76, the external force is removed. The first spring 74, previously compressed, releases its elasticity, pushing the stop block 75 and causing the pin 73 to move in the opposite direction. This allows the pin 73 to re-insert into the corresponding socket 72. The engagement of the pin 73 and the socket 72 fixes the position of the connecting block 71, thus locking the upper clamp 6 in place. It is worth noting that the second spring 10 at the bottom left end of the upper clamp 6 plays a crucial role throughout the adjustment process.When adjusting the position of the upper clamping plate 6, the second spring 10 will compress or stretch as the upper clamping plate 6 moves, which plays a buffering role and prevents the upper clamping plate 6 from damaging the cable body 9 due to rapid movement. At the same time, the elastic force generated by the second spring 10 provides auxiliary support for the upper clamping plate 6, ensuring the stability of the upper clamping plate 6 during the adjustment process. Furthermore, when finally clamping the cable body 9, it can provide a moderate clamping force to ensure that the cable body 9 is stably clamped without being damaged due to excessive clamping force.

[0024] like Figures 1 to 5 As shown, an arc-shaped groove 5 is provided on the side of the lower clamping plate 11 opposite to the wiring plate 4. The arc-shaped groove 5 communicates with the groove 12. The cable body 9 is provided on the inner side of the arc-shaped groove 5. A power assembly 8 is provided on the top of the base plate 1. The power assembly 8 includes two mounting plates 81, which are fixedly connected to the top of the base plate 1. A gear 82 is rotatably connected between the two mounting plates 81. A gear ring 84 is fixedly connected to the outer side of the connecting column 3. The gear ring 84 meshes with the gear 82. A self-locking motor 83 is fixedly connected to the outer side of the mounting plate 81. The output end of the self-locking motor 83 passes through the mounting plate 81 and is fixedly connected to the gear 82. When it is necessary to automatically adjust the position of the upper clamping plate 6 to complete the clamping operation of the cable body 9, the self-locking motor 83 is powered on and started. The output end of the self-locking motor 83 is fixedly connected to the gear 82. After the motor starts, the output end generates rotational power, which directly drives the gear 82 to rotate around its own rotation axis. In the device's structural design, gear 82 meshes with a gear ring 84 fixedly connected to the outer side of the connecting column 3. The rotation of gear 82 transmits power through the meshing of the teeth between gear 82 and gear ring 84, causing gear ring 84 to rotate accordingly. Since gear ring 84 is fixedly connected to connecting column 3, the rotation of gear ring 84 drives connecting column 3 to rotate synchronously. Connecting column 3 is also connected to adjusting assembly 7, so the rotation of connecting column 3 further drives the movement of various components in adjusting assembly 7, ultimately achieving automatic adjustment of the position of upper clamping plate 6. In this power transmission process, the two mounting plates 81 play an indispensable supporting and positioning role. Mounting plates 81 are fixedly connected to the top of base plate 1, providing a stable support structure for gear 82 and connecting column 3, ensuring that gear 82 and connecting column 3 maintain the correct position and posture during rotation, and preventing swaying or displacement from affecting the stability and accuracy of power transmission. In addition, the self-locking motor 83 has a unique self-locking function. When the upper clamping plate 6 is adjusted to a suitable position by the motor, the self-locking mechanism inside the motor is activated and automatically locks the output shaft of the motor to prevent the connecting column 3 from rotating due to external forces such as vibration and impact. This ensures the fixed position of the upper clamping plate 6 and achieves stable and reliable clamping of the cable body 9, providing a solid guarantee for subsequent wiring operations.

[0025] Working principle: First, when it is necessary to adjust the upper clamping plate 6 to adapt to different specifications of cable body 9, the operator pulls the handle 76, which moves the stop block 75 and the pin 73, so that the pin 73 overcomes the elastic force of the first spring 74 and is pulled out of the socket 72 of the connecting block 71. At this time, the connecting rod 77 can rotate freely around the rotation point of the connecting block 71, thereby driving the upper clamping plate 6 to rotate around the connecting post 3, changing the distance between the upper clamping plate 6 and the lower clamping plate 11. After the adjustment is in place, the handle 76 is released, and the first spring 74 pushes the pin 73 to re-insert into the socket 72, locking the position of the connecting block 71 and the upper clamping plate 6. At the same time, the second spring 10 at the bottom left end of the upper clamping plate 6 plays the role of buffering, auxiliary support and providing appropriate clamping force. If automatic adjustment is required, the power supply of the self-locking motor 83 is turned on, and its output end drives the gear 82 to rotate. Through the meshing transmission between the gear 82 and the gear ring 84, the connecting column 3 is rotated, which in turn drives the adjustment component 7 to achieve automatic adjustment of the position of the upper clamping plate 6. During this process, the two mounting plates 81 provide stable support for the gear 82 and the connecting column 3 to ensure the accuracy of power transmission. After the adjustment is completed, the self-locking mechanism inside the self-locking motor 83 is activated to lock the motor output shaft, preventing the connecting column 3 from rotating due to external force, ensuring that the upper clamping plate 6 is stably fixed, and the cable body 9 is placed between the groove 12 of the lower clamping plate 11 and the upper clamping plate 6 to complete the clamping, preparing for subsequent wiring operations.
