Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and specifically relates to a wiring device for a distribution cabinet. Background Technique

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the end - level equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper - level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring, and control for the load.

[0003] According to the Chinese patent with the publication number: CN217306958U, a wiring - type distribution cabinet and a wiring device for a distribution cabinet, including a distribution cabinet body, a fixed seat is fixedly installed on the right - hand surface of the distribution cabinet body. A wire - passing groove opening is formed on the surface of the fixed seat, and the wire - passing groove opening penetrates and communicates with the inside of the distribution cabinet body. Clamping devices are symmetrically arranged on the upper and lower sides of the wire - passing groove opening inside the fixed seat. An extrusion device is arranged on one side of the wire - passing groove opening inside the fixed seat, and the extrusion device is in corresponding structural cooperation with the clamping devices.

[0004] In the above - mentioned scheme, two mutually - approaching arc - shaped clamping openings clamp the wire inside, but it still has the following disadvantages: the diameter of the arc - shaped clamping openings is fixed, which is suitable for fixing wires with a larger diameter. When it is necessary to clamp and fix a wire with a diameter smaller than that of the arc - shaped clamping openings, the inner wall surface of the arc - shaped clamping openings cannot fully contact the surface of the wire, and wires with different diameters may not be fixed well. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wiring device for a distribution cabinet to solve the problem that when it is necessary to clamp and fix a wire with a diameter smaller than that of the arc - shaped clamping openings, the inner wall surface of the arc - shaped clamping openings cannot fully contact the surface of the wire, and wires with different diameters may not be fixed well.

[0006] To achieve the above - mentioned utility model purpose, the utility model adopts the following technical scheme: A wiring device for a distribution cabinet, including a housing, an installation and unloading plate is detachably arranged inside the housing. A communication port is opened on the inner bottom surface of the housing, a penetration port is opened on the top surface of the installation and unloading plate. A fixing plate is fixed on one side inside the housing. A turning plate is rotatably arranged on one side of the fixing plate through a hinge. Two middle - layer plates are rotatably arranged between the fixing plate and the turning plate through hinges. A number of extrusion grooves are respectively opened on one side of the fixing plate and one side of the two middle - layer plates. A number of placement grooves are respectively opened on the other side of the turning plate and the other side of the two middle - layer plates. Two sliding grooves are opened inside the extrusion grooves, and elastic plates are slidably inserted inside the sliding grooves.

[0007] Preferably, a connecting band is fixed to one side of the fixing plate. A plurality of fixing holes are formed in one side of the connecting band. Fixing columns are respectively fixed to one sides of the middle layer plate and the flipping plate. A limiting ring is fixedly inserted on the fixing column. The fixing column is slidably inserted into the fixing hole.

[0008] Preferably, limiting grooves are respectively formed on both sides inside the outer shell. Limiting strips are respectively fixed to both sides of the loading and unloading plate. The limiting strips are slidably arranged in the limiting grooves. A buckling groove is formed on the top surface of the loading and unloading plate.

[0009] Preferably, two supporting folding plates are fixed to one side of the outer shell. A plurality of through holes are formed in one side of the supporting folding plate. A positioning opening is formed on the inner wall surface of the through hole.

[0010] Preferably, a cabinet door is rotatably arranged on one side of the outer shell through a hinge. An installation opening is formed on one side of the cabinet door. An observation window is fixed inside the installation opening.

[0011] Preferably, a blower is fixed to the top surface of the outer shell. One end of the air extraction pipe of the blower passes through the top surface of the outer shell and extends into the interior of the outer shell. A plurality of ventilation openings are respectively formed on both sides of the outer shell.

[0012] Compared with the prior art, a wiring device of a power distribution cabinet adopting the above technical scheme has the following beneficial effects:

[0013] First, when a worker wires the wires inside the outer shell, the worker will place a section of the wire in the extrusion groove. Then the worker flips the middle layer plate to fit against one side of the fixing plate, and the wire can be stored in the extrusion groove and the placement groove. Then the worker fits the connecting band against one sides of the flipping plate and the middle layer plate, and makes the fixing column pass through the fixing hole to fix the positions of the flipping plate, the middle layer plate and the fixing plate relative to each other. During this process, the wire will exert an extrusion force on the elastic plate, and by using the elasticity of the elastic plate to exert an extrusion force on the wire, the firmness of the position of wires with different diameters inside the extrusion groove can be increased;

[0014] Second, the worker can adjust the utilization rate of the space inside the outer shell by changing the installation height of the loading and unloading plate inside the outer shell. When installing the outer shell on the wall, the worker will first drive two rows of horizontally arranged cement nails into the wall. Then the worker will pass one end of the cement nail through the through hole. Subsequently, when the outer shell moves downward due to its own gravity, the cement nail will enter the positioning opening, thereby increasing the firmness of the outer shell when hanging on the wall;

[0015] Third, during the operation of the power distribution cabinet, the equipment inside the outer shell will generate heat. Part of this heat will be discharged from the interior of the outer shell through the ventilation openings, and the remaining heat will be extracted from the interior of the outer shell by the blower, thereby reducing the temperature of the environment inside the outer shell.
