Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and more specifically, to an auxiliary wiring device inside a distribution box. Background Art

[0002] Distribution boxes are characterized by small volume, simple installation, special technical performance, fixed position, unique configured functions, unrestricted by site, wide application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. They are the control centers for rationally distributing electric energy among various components in the power supply line, the control links for reliably receiving the upper-end power supply and correctly feeding out the load electric energy, and also the key to obtaining user satisfaction with the power supply quality. Improving the operation reliability of power distribution boxes is the goal of creating high-quality projects. The massive parameters in the distribution box data generally constitute low-voltage electrical wiring, which requires assembling switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or panel to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected manually or automatically. In case of faults or abnormal operation, the circuit can be cut off or an alarm can be given by the protective electrical appliance. Various parameters during operation can be displayed by the measuring instrument, and some electrical parameters can also be adjusted, and prompts or signals can be sent for deviations from the normal working state. The distribution box structure is divided into two types: welded structure, which simply cuts, bends, punches and then welds sheet metal parts; assembled structure, where sheet metal parts are processed separately and assembled after each part is processed, and are reinforced and locked with screws and tees. It has a beautiful appearance and simple operation, and can save a large amount of transportation costs. When in use, to ensure the normal operation of the distribution box, external wires need to be connected to provide power, which requires the use of a wiring device to protect the external wires.

[0003] Among them, the patent with publication number CN115912073A discloses a wiring device for a distribution box, which relates to the technical field of distribution boxes and includes a mounting plate. Mounting holes are provided at the four corners of the front surface of the mounting plate, and a waterproof mechanism is arranged on the front surface of the mounting plate; the waterproof mechanism includes a fixed block, side plates, a baffle, a circular hole one, a rubber ring, a rectangular groove, a rectangular block, a wiring block, and a circular hole two. The outer wall of the back surface of the fixed block is fixedly connected to the outer wall of the front surface of the mounting plate, and the bottom of the side plate is fixedly connected to the bottom of the fixed block, and the number of side plates is two;

[0004] When this structure is in use, the mounting plate is installed at the wire hole on the distribution box through the mounting holes, so that the external wire passes through the circular hole two and the circular hole one. The rubber ring can seal the gap between the external wire and the circular hole one. Together with the two side plates, this wiring device can well prevent rainwater from entering the distribution box and avoid damaging the internal circuit of the distribution box. However, when this structure is in use, it is not easy to separate and comb different wires, resulting in messy wiring, and it is not easy to adjust the tightness during wiring, making the wiring less convenient. Summary of the Invention

[0005] To overcome the above defects of the prior art, the present invention provides an auxiliary wiring device inside a distribution box, aiming to solve the problems raised in the above background art.

[0006] The present invention provides the following technical solutions: an auxiliary wiring device inside a distribution box, including a distribution box housing, on which a power distribution wiring component is provided;

[0007] The power distribution wiring component includes a support frame bolted to one side of the bottom inner wall of the distribution box housing, and a number of IGBT modules are bolted to the support frame;

[0008] One side of the top inner wall of the distribution box housing is bolted with a wire row rack, and a number of adjustable vertical plates are arranged on the outer side of the wire row rack. A number of angle-adjustable connecting plates are hinged on each of the vertical plates, and a wire arranging row for wire arranging is arranged on one side of each of the connecting plates;

[0009] A number of limiting blocks are distributed at the bottom of the wire row rack, and each of the limiting blocks is bolted to the bottom of the wire row rack. A number of first guiding grooves are penetrated through the plurality of limiting blocks, and a vertical shaft block is slidably connected in each of the first guiding grooves. A wire dividing rod is fixedly arranged at the bottom of each of the vertical shaft blocks, and an articulated sleeve for tensioning the cable is hinged on each of the wire dividing rods. An insulating cable bundling sleeve body for positioning the cable is arranged at the bottom of each of the articulated sleeves. A wire arranging groove for wire arranging is penetrated through each of the wire arranging rows, and the wire arranging rows are stacked. The plurality of limiting blocks are respectively located at the bottoms of the corresponding vertical plates. A number of second guiding grooves are penetrated through the wire row rack, and each of the second guiding grooves is respectively located at the bottom of the corresponding vertical plate. A through hole is penetrated through one side of the surface of each of the second guiding grooves. A pulley is threadedly connected to the bottom of each of the vertical plates, and each of the pulleys penetrates through the corresponding second guiding groove and extends to one side of the wire row rack;

[0010] It can be seen that in the above technical solution, the wire is positioned by the insulating wire bundle sleeve body, which facilitates the tapping of the wire on the electrical equipment or the IGBT module. At the same time, the traction rod is driven to rotate by the micro motor. When the traction rod rotates, it drives the pull rod to displace and deflect the pull rod. When the pull rod deflects, it drives the vertical shaft block to slide in the first guide groove, and then enables the wire dividing rod, the hinge sleeve and the insulating wire bundle sleeve body to be finely adjusted on the limit block, adjusts the positions of the hinge sleeve and the insulating wire bundle sleeve body, and realizes that when the wire penetrates through the insulating wire bundle sleeve body and is connected, the wire contacts different positions, avoids the wire falling off due to the lack of support at the connection of the wire and the equipment to be connected, ensures the wiring stability, restricts the main cable through the limit block, and adjusts the positions of each wire arranging row by the way of gathering and spreading the vertical plate towards the axis of the lead screw, so as to realize the function of tension adjustment of the main cable;

[0011] Optionally, in a possible implementation manner, a plurality of micro motors are installed on the limit block through bolts, and a traction rod is fixedly arranged at the output end of each micro motor. A plurality of adjustment holes are penetrated through each of the plurality of traction rods. One end of the traction rod is provided with a pull rod. One end of the pull rod is fixedly provided with a limit shaft, and the limit shaft extends into the adjustment hole and is rotatably connected with the adjustment hole. The pull rod extends to the vertical shaft block and is rotatably connected with the vertical shaft block. A lead screw is rotatably connected to the wire arranging row frame. A threaded cylinder is threadedly connected to the outer side of the lead screw. A plurality of shaft hole plates are fixedly arranged on the outer side of the threaded cylinder. The plurality of shaft hole plates are respectively located on one side of the corresponding vertical plate. A shaft pin member for driving the vertical plate to displace is hinged on each shaft hole plate, and one end of each shaft pin member extends to and is rotatably connected with the vertical plate. One end of each of the plurality of wire arranging rows is fixedly provided with a spring. A plurality of sliding grooves for guiding are penetrated through the outer side of the wire arranging row frame, and the plurality of sliding grooves are respectively located on one side of the bottom of the corresponding vertical plate. A sliding plate is slidably connected in each of the plurality of sliding grooves, and one end of each spring extends to the wire arranging row frame and the sliding plate respectively. A driving motor for driving the lead screw to rotate is installed on one side of the wire arranging row frame through bolts. A frequency converter detachably connected to the distribution box housing by bolts is arranged on the top of the support frame. A power connection pin board is arranged on one side of the inner wall of the distribution box housing. The power connection pin board is connected with the frequency converter through a wire. The frequency converter is connected with the IGBT module through a wire;

[0012] It can be seen that in the above technical solution, when the vertical plate, the connecting plate and the wire arranging row are adjusted in position on the wire arranging row frame, the wire arranging row is limited by the spring when it displaces, which will cause the wire arranging row to rotate along the axis point of the connection between the connecting plate and the vertical plate, and then realize the function of angle adjustment of the wire arranging row and the connecting plate. At the same time, it is elastically supported by the spring, so that the main cable can also be deformed and finely adjusted after the tension adjustment, and then the wire arranging row is driven to reset by the elasticity of the spring itself, so that the main cable can be in an elastically supported state after being fixed.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The vertical plate of the present invention displaces on the online rack, and the displacement of the vertical plate is guided by the pulley and the second guiding groove. Then it penetrates through the through hole, and at the same time, the main cable is constrained by the limiting block. The positions of each wire arranging row are adjusted by the way that the vertical plate gathers and diffuses towards the axis of the lead screw, realizing the function of tension adjustment of the main cable;

[0015] 2. The shunt conductors in the main cable of the present invention respectively penetrate through the corresponding insulating wire bundling sleeve bodies. The wire dividing rod, the articulated sleeve and the insulating wire bundling sleeve body can be finely adjusted on the limiting block to adjust the positions of the articulated sleeve and the insulating wire bundling sleeve body. When wiring after the conductors penetrate through the insulating wire bundling sleeve body, different positions of the conductors are in contact, avoiding the conductors from falling off due to the lack of support at the connection with the equipment to be wired, and ensuring the wiring stability;

[0016] 3. When the wire arranging row displaces, it is limited by the spring, which will cause the wire arranging row to rotate around the axis point at the connection of the connecting plate and the vertical plate, thereby realizing the function of angle adjustment of the wire arranging row and the connecting plate. At the same time, it is elastically supported by the spring, enabling the main cable to perform corresponding deformation fine adjustment after tension adjustment. Then, through the elastic drive of the spring itself, the wire arranging row is reset, so that the main cable can be in an elastically supported state after being fixed;

[0017] 4. One end of the conductor of the present invention is installed on the power connection pin board, and the power connection pin board conveys current to the frequency converter. After the current conversion by the frequency converter, the current is conveyed to the IGBT module through the conductor, which is convenient for each IGBT module to shunt and convey the current;

[0018] In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the main cable is constrained by the limiting block, and the positions of each wire arranging row are adjusted by the way that the vertical plate gathers and diffuses towards the axis of the lead screw, realizing the function of tension adjustment of the main cable. The shunt conductors in each main cable respectively penetrate through the corresponding insulating wire bundling sleeve bodies, and the conductors are positioned by the insulating wire bundling sleeve bodies, which is convenient for the conductors to be branched and connected to electrical equipment or IGBT modules. The wire dividing rod, the articulated sleeve and the insulating wire bundling sleeve body can be finely adjusted on the limiting block to adjust the positions of the articulated sleeve and the insulating wire bundling sleeve body. When wiring after the conductors penetrate through the insulating wire bundling sleeve body, different positions of the conductors are in contact, avoiding the conductors from falling off due to the lack of support at the connection with the equipment to be wired, and ensuring the wiring stability. It is elastically supported by the spring, enabling the main cable to perform corresponding deformation fine adjustment after tension adjustment. Then, through the elastic drive of the spring itself, the wire arranging row is reset, so that the main cable can be in an elastically supported state after being fixed. Description of the Drawings
