Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more specifically, to a low-voltage integrated distribution box with an optimized electrical connection structure. Background Technology

[0002] The low-voltage integrated distribution box (also known as JP cabinet) is an outdoor power distribution device that integrates multiple functions such as power distribution, protection, control, measurement, metering and reactive power compensation. It is widely used in urban and rural power grids in conjunction with 10kV pole-mounted transformers.

[0003] Core functions and components: Power distribution and control: Power distribution is achieved through incoming line switches and feeder circuits, supporting manual or automatic switching operations.

[0004] Currently, low-voltage integrated distribution boxes mostly rely on manual installation of circuits and electrical components. Circuit connections primarily depend on electrical wires, which are installed using two different methods. 1. With connecting clips: Wires with connecting clips usually refer to metal connecting devices with metal ends that are shaped like a "C" or have round holes. During installation, they are simply inserted and tightened to the electrical components using screws. 2. Conventional wires: The insulation of the conventional wires is stripped manually, and the wires are manually screwed until the ends have round holes. During installation, screws are used to fasten the wires to the electrical components.

[0005] Existing low-voltage integrated distribution boxes are mostly installed manually in sequence, which is inefficient. Therefore, it is particularly important to propose a low-voltage integrated distribution box that can be pre-assembled for efficient on-site installation. In view of this, we propose a low-voltage integrated distribution box with an optimized electrical connection structure. Summary of the Invention

[0006] The purpose of this invention is to provide a low-voltage integrated distribution box with an optimized electrical connection structure to solve the technical problem of low efficiency in traditional manual installation.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a low-voltage integrated distribution box with an optimized electrical connection structure, comprising a low-voltage integrated distribution box body; the low-voltage integrated distribution box body internally provides a capacitor chamber cavity, a metering chamber cavity, and an incoming line chamber cavity; the incoming line chamber cavity internally provides a connection system for electrical connection of low-voltage lines; the connection system includes a connection frame arranged within the incoming line chamber cavity; an electrical unit for controlling the on / off state of the circuit is fixedly mounted on the connection frame; batch control units for controlling the connection between the low-voltage lines and the connection terminals of the electrical unit are respectively arranged on the upper and lower sides of the electrical unit; the batch control... The unit includes a fixed connecting base plate fixed to the connecting frame; each fixed connecting base plate is provided with a follower rotation mechanism at a position relative to the connection end of the electrical unit; and the output end of the follower rotation mechanism is provided with an adjustment mechanism on both sides of the fixed connecting base plate; a primary drive key shaft is keyed inside the follower rotation mechanism; a secondary drive adjustment shaft is threaded inside the primary drive key shaft; the ends of several secondary drive adjustment shafts are all mounted and connected through a synchronous seat; a pushing mechanism is provided on both sides of the fixed connecting base plate; wherein, a drive adjustment block is movably provided at the end of the primary drive key shaft, and the drive adjustment block is hinged to the secondary drive adjustment shaft.

[0008] This invention uses an adjustment mechanism to rotate the follower rotation mechanism and the primary drive key shaft, causing them to rotate. The primary drive key shaft and the secondary drive adjustment shaft, connected by threads, cause the primary drive key shaft to move in a relative advancing or retracting motion, thus enabling the connection and installation adjustment of the ends of two different electrical wires with the electrical unit connection end. At the same time, a pushing mechanism is used to synchronously advance or retract the primary drive key shaft and the secondary drive adjustment shaft, thus enabling further installation work. The above method effectively simplifies the installation operation and enables batch rapid circuit disconnection adjustment operations.

[0009] Preferably, the follow-up rotation mechanism includes a plurality of bearing rotating seats arranged on the fixed connecting base plate; a connecting bushing is provided inside the bearing rotating seat; and at least one limiting key is provided inside the connecting bushing; a synchronous wheel is fixedly provided on the outer surface of the connecting bushing.

[0010] Preferably, the adjustment mechanism includes drive wheels arranged on both sides of the fixed connection base plate via mounting base A; a drive shaft is provided at the end of the drive wheel opposite to the door opening side of the low-voltage integrated distribution box; and a synchronous belt is provided on the outer surface of the drive wheel; and the synchronous belt is connected to a plurality of the synchronous pulleys for transmission.

[0011] Preferably, the surface of the primary drive key shaft is provided with a keyway that matches the limiting key teeth; and the end of the primary drive key shaft is provided with a connecting part A; and the end of the connecting part A is provided with an adjustment cavity; a centrally hinged sliding groove is provided in the middle of one side of the adjustment cavity; and an inclined auxiliary adjustment groove is provided on the other side of the adjustment cavity.

[0012] Preferably, the end of the secondary drive adjustment shaft is fixedly connected to the synchronous seat, and the secondary drive adjustment shaft is threadedly connected to the primary drive key shaft; and the end of the secondary drive adjustment shaft is rotatably provided with a rotating part that is hingedly connected to the drive adjustment block.

[0013] Preferably, the propulsion mechanism includes a guide shaft fixed to the connecting frame via a mounting base B; and the other end of the guide shaft is rotatably arranged on the fixed connecting base via a mounting base C; and all guide shafts pass through the surface of the synchronizing seat; and at least one of the guide shaft surfaces is provided with drive screw teeth that are threadedly connected to the synchronizing seat.

[0014] Preferably, the drive adjustment block is hinged to the secondary drive adjustment shaft, and the drive adjustment block has a radial limiting protrusion on the side closer to the central hinge slide groove; the drive adjustment block has an adjustment protrusion on the side closer to the auxiliary adjustment groove; and the drive adjustment block has a V-shaped transition groove on the side closer to the end of the electrical unit. Preferably, the drive adjustment block has two working states: In the first working state, the adjustment protrusion slides along the auxiliary adjustment groove to make the drive adjustment block folded, forming a direct-insertion electrical connection structure. In the second working state, the adjustment protrusion slides along the auxiliary adjustment groove to make the drive adjustment block unfold, forming a hook-type electrical connection structure.

[0015] Preferably, the switching between the two working states is controlled by the rotation direction of the drive shaft. When rotating in the forward direction, the drive wheel drives the synchronous wheel to rotate in the forward direction through the synchronous belt to achieve the first working state, and when rotating in the reverse direction, the second working state is achieved.

[0016] A method of using a low-voltage integrated distribution box with optimized electrical connection structure includes the following steps: S100, Basic Processing: The electrical connections of the low-voltage integrated distribution box are manually sorted out; S200, Adjustment Process: The rotation of the drive shaft causes the drive wheel to drive several synchronous wheels to rotate, so that the fixedly connected secondary drive adjustment shaft remains stationary. During the rotation, the primary drive key shaft performs a relative advancing motion. The drive adjustment block is kept in the hinge center position by the radial limiting protrusion and the central hinge sliding groove. The drive adjustment block is also retracted and folded by the adjustment protrusion and the inclined auxiliary adjustment groove. S300, Connection Processing: For connecting wires with mounting copper clips: by rotating the guide shaft with drive screw teeth, the secondary drive adjustment shaft and the primary drive key shaft are pushed to move, causing the drive adjustment block to be inserted into the mounting hole of the electrical unit connection end; then, the mounting copper clips of the wires with mounting copper clips are manually fitted onto the connection part A in sequence; by rotating the drive shaft, the drive wheel drives several synchronous wheels to rotate, causing the fixedly connected secondary drive adjustment shaft to remain stationary, while the primary drive key shaft retracts relative to the rotation. The drive adjustment block is kept in the hinge center position by the radial limiting protrusion and the centrally hinged sliding groove, and the drive adjustment block is rotated and unfolded by the adjustment protrusion and the inclined auxiliary adjustment groove. If connecting wires without copper clips: Based on step S200, manually clip the exposed ends of the wires with copper clips into the transition grooves one by one. S400, Fastening treatment: If the wire with copper clip is fastened: by rotating the guide shaft with drive screw teeth in the positive direction, the first-stage drive key shaft and the second-stage drive adjustment shaft are retracted as a whole, and the wire with copper clip is tightly attached to the electrical unit connection end under the hook of the drive adjustment block. To secure wires without copper clips: By rotating the guide shaft with drive screw teeth in opposite directions, the first-stage drive key shaft and the second-stage drive adjustment shaft are pushed forward as a whole. Under the clamping of the drive adjustment block, the exposed end of the wire is squeezed into the electrical unit connection end channel in a "V" shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an adjustment mechanism to rotate the follower rotation mechanism and the primary drive key shaft, causing them to rotate. The primary drive key shaft and the secondary drive adjustment shaft are connected by threads, causing the primary drive key shaft to move in a relative advancing or retracting motion to adjust the connection between the ends of two different electrical wires and the electrical unit. At the same time, a pushing mechanism is used to synchronously advance or retract the primary drive key shaft and the secondary drive adjustment shaft to perform further installation work. The above method effectively simplifies the installation operation and enables batch rapid circuit disconnection adjustment operations.

[0018] 2. This invention applies torque to the drive shaft using a tool, causing the drive wheel to rotate and drive several synchronous wheels to rotate. This keeps the fixed secondary drive adjustment shaft stationary, while the primary drive key shaft moves in a relative advancing or retracting motion during rotation, thus providing the power input for adjusting the movement of the drive adjustment block.

[0019] 3. The present invention connects the primary drive key shaft surface keyway with the limiting key teeth, so that the primary drive key shaft is subjected to rotational torque power input at different axial positions.

[0020] 4. This invention uses a tool rotation belt with a drive screw tooth guide shaft to cause the synchronous seat to move synchronously forward or backward. This method drives the first-stage drive key shaft for batch installation and matching installation operations.

[0021] 5. This invention maintains the hinge center position of the drive adjustment block by using a radial limiting protrusion and a centrally located hinged sliding groove for central limiting and sliding. Through the adjustment protrusion and the inclined auxiliary adjustment groove, the drive adjustment block rotates during the advancing or retracting motion of the primary drive key shaft. The horizontal drive adjustment block is used for installing electrical wiring without copper clips; the rotated, near-vertical drive adjustment block is used for installing electrical wiring with copper clips, thus achieving diverse installation operations.

[0022] 6. The present invention features a V-shaped transition groove at the end of the drive adjustment block. During the installation of electrical wiring without copper clips, the inclined surface of the transition groove ensures that the electrical wires with copper clips are tightly connected to the electrical unit connection end during the synchronous pushing of the first-stage drive key shaft and the second-stage drive adjustment shaft, achieving a good and stable installation effect.

This invention uses the adjustment mechanism 8 to rotate, causing the follower rotation mechanism 7 and the primary drive key shaft 9 to rotate. The primary drive key shaft 9 and the secondary drive adjustment shaft 10, connected by threads, cause the primary drive key shaft 9 to move in a relative advancing or retracting motion, thus performing the connection and installation adjustment operation for the connection end of two different electrical wires with the electrical unit 4. At the same time, the advancing mechanism 12 performs synchronous advancing or retracting motion of the primary drive key shaft 9 and the secondary drive adjustment shaft 10 to perform further installation work. The above method effectively simplifies the installation operation and enables batch rapid circuit disconnection adjustment operation.

[0026] In an embodiment of the present invention, the follower rotation mechanism 7 includes a plurality of bearing rotating seats 701 arranged on a fixed connecting base plate 6; a connecting bushing 702 is provided inside the bearing rotating seat 701; and at least one limiting key tooth 7021 is provided inside the connecting bushing 702; a synchronous wheel 7022 is fixedly provided on the outer surface of the connecting bushing 702.

[0027] In an embodiment of the present invention, the adjustment mechanism 8 includes drive wheels 801 arranged on both sides of the fixed connecting base plate 6 via mounting base A; a drive shaft 8011 is provided at the end of the drive wheel 801 relative to the door opening side of the low-voltage integrated distribution box 1; and a synchronous belt 802 is provided on the outer surface of the drive wheel 801; and the synchronous belt 802 is connected to several synchronous pulleys 7022 for transmission. The present invention applies torque to the drive shaft 8011 by means of a tool, causing the drive wheel 801 to drive several synchronous pulleys 7022 to rotate, so that the fixed secondary drive adjustment shaft 10 remains stationary, and the primary drive key shaft 9 performs relative pushing or retracting motion during rotation to realize the power input for adjusting the drive adjustment block 13.

[0028] In an embodiment of the present invention, the surface of the primary drive key shaft 9 is provided with a keyway 901 adapted to the limiting key teeth 7021; and the end of the primary drive key shaft 9 is provided with a connecting portion A902; and the end of the connecting portion A902 is provided with an adjustment cavity; a centrally hinged sliding groove 9021 is provided at the middle of one side of the adjustment cavity; and an inclined auxiliary adjustment groove 9022 is provided on the other side of the adjustment cavity.

[0029] In an embodiment of the present invention, the end of the secondary drive adjustment shaft 10 is fixedly connected to the synchronous seat 11, and the secondary drive adjustment shaft 10 is threadedly connected to the primary drive key shaft 9; and the end of the secondary drive adjustment shaft 10 is rotatably provided with a rotating part that is hingedly connected to the drive adjustment block 13.

[0030] In an embodiment of the present invention, the propulsion mechanism 12 includes a guide shaft 1201 fixed to the connecting frame 3 via a mounting base B; the other end of the guide shaft 1201 is rotatably arranged on the fixed connecting base plate 6 via a mounting base C; all guide shafts 1201 pass through the surface of the synchronization seat 11; and at least one guide shaft 1201 has a drive screw 1202 threadedly connected to the synchronization seat 11 on its surface. The present invention uses the tool rotation along the guide shaft 1201 with the drive screw 1202 to cause the synchronization seat 11 to synchronously perform propulsion or retraction movements, thereby driving the primary drive key shaft 9 for batch installation operations and matching installation operations.

[0031] In an embodiment of the present invention, the drive adjustment block 13 is hinged to the secondary drive adjustment shaft 10, and the drive adjustment block 13 is provided with a radial limiting protrusion 1301 on the side closer to the central hinge groove 9021; the drive adjustment block 13 is provided with an adjustment protrusion 1302 on the side closer to the auxiliary adjustment groove 9022. The present invention maintains the hinge center position of the drive adjustment block 13 by the radial limiting protrusion 1301 and the central hinge groove 9021 in a centrally limited sliding configuration. By adjusting the protrusion 1302 and the inclined auxiliary adjustment groove 9022, the drive adjustment block 13 is rotated during the advancing or retracting movement of the primary drive key shaft 9. The horizontal state of the drive adjustment block 13 is used to accommodate the installation of electrical circuits without copper clips; the near-vertical state of the rotated drive adjustment block 13 is used to accommodate the installation of electrical circuits with copper clips, thus achieving diverse installation operations.

[0032] In an embodiment of the present invention, a V-shaped transition groove 1303 is provided on the drive adjustment block 13 near the end of the electrical unit 4.

[0033] In an embodiment of the present invention, the drive adjustment block 13 has two working states; In the first working state, the adjustment protrusion 1302 slides along the auxiliary adjustment groove 9022 to make the drive adjustment block 13 folded, forming a direct-insertion electrical connection structure. The present invention rotates the drive shaft 8011, causing the drive wheel 801 to drive several synchronous wheels 7022 to rotate, so that the fixedly connected secondary drive adjustment shaft 10 remains stationary. During the rotation, the primary drive key shaft 9 performs relative pushing motion. The drive adjustment block 13 is kept in the hinge center position by the radial limiting protrusion 1301 and the centrally hinged sliding groove 9021. The adjustment protrusion 1302 and the inclined auxiliary adjustment groove 9022 cause the drive adjustment block 13 to retract and fold. The push mechanism 12 drives the end of the primary drive key shaft 9 to be inserted into the mounting hole of the electrical unit 4 connection end. The transition groove 1303 is used to fasten and press the electrical line without copper buckle into the mounting hole of the electrical unit 4 connection end, forming a direct-insertion electrical line installation structure. In the second working state, the adjusting protrusion 1302 slides along the auxiliary adjusting groove 9022, causing the drive adjusting block 13 to unfold, forming a hook-type electrical connection structure. The switching between the two working states is controlled by the rotation direction of the drive shaft 8011. When rotating in the forward direction, the drive wheel 801 drives the synchronous wheel 7022 to rotate in the forward direction through the synchronous belt 802 to achieve the first working state. When rotating in the reverse direction, the second working state is achieved. In this invention, the push mechanism 12 drives the end of the first-stage drive key shaft 9 to be inserted into the mounting hole at the connection end of the electrical unit 4. The rotation of the drive shaft 8011 causes the drive wheel 801 to drive several synchronous wheels 7022 to rotate. The operation causes the fixed secondary drive adjustment shaft 10 to remain stationary, while the primary drive key shaft 9 retracts relative to it during rotation. The drive adjustment block 13 is kept in the hinge center position by the radial limiting protrusion 1301 and the centrally hinged sliding groove 9021. The drive adjustment block 13 is rotated and unfolded by adjusting the protrusion 1302 and the inclined auxiliary adjustment groove 9022. Driven by the propulsion mechanism 12, the primary drive key shaft 9 and the secondary drive adjustment shaft 10 retract synchronously, hooking the electrical wiring and electrical unit 4 connection end of the copper buckle; forming a hook-type electrical wiring installation structure.

[0034] In an embodiment of the present invention, the switching between the two working states is controlled by the rotation direction of the drive shaft 8011. When rotating in the forward direction, the drive wheel 801 drives the synchronous wheel 7022 to rotate in the forward direction through the synchronous belt 802 to achieve the first working state, and when rotating in the reverse direction, the second working state is achieved.

During the rotation, the primary drive key shaft 9 performs relative propulsion movement. The drive adjustment block 13 is kept in the hinge center position by the radial limiting protrusion 1301 and the centrally hinged slide groove 9021. The drive adjustment block 13 is retracted and folded by adjusting the protrusion 1302 and the inclined auxiliary adjustment groove 9022. S300, Connection Processing: If the wire with copper clip is connected: by rotating the guide shaft 1201 with drive screw teeth 1202, the secondary drive adjustment shaft 10 and the primary drive key shaft 9 are pushed to move, causing the drive adjustment block 13 to be inserted into the mounting hole of the electrical unit 4 connection end; then, the copper clips of the wire with copper clip are manually put onto the connection part A902 in sequence; by rotating the drive shaft 8011, the drive wheel 801 drives several synchronous wheels 7022 to rotate, so that the fixed secondary drive adjustment shaft 10 remains stationary, and the primary drive key shaft 9 retracts relatively during the rotation. The drive adjustment block 13 is kept in the hinge center position by the radial limiting protrusion 1301 and the centrally hinged sliding groove 9021, and the drive adjustment block 13 is rotated and unfolded by adjusting the protrusion 1302 and the inclined auxiliary adjustment groove 9022. If the wires without copper clips are to be connected: Based on step S200, the exposed ends of the wires with copper clips are manually clipped into the transition groove 1303 one by one; S400, Fastening treatment: If the wire with copper buckle is fastened: by rotating the guide shaft 1201 with drive screw 1202 in the forward direction, the first-stage drive key shaft 9 and the second-stage drive adjustment shaft 10 are retracted as a whole, and the wire with copper buckle is tightly attached to the connection end of the electrical unit 4 under the hook of the drive adjustment block 13. If the wire without copper clip is to be fastened: by rotating the guide shaft 1201 with drive screw teeth 1202 in opposite directions, the first-stage drive key shaft 9 and the second-stage drive adjustment shaft 10 are pushed forward as a whole. Under the clamping of the drive adjustment block 13, the exposed end of the wire is squeezed into the connection end channel of the electrical unit 4 in a "V" shape.
