Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet that is easy to install. Background Technology
[0002] A power distribution cabinet is an electrical device used to distribute and control power. It is usually installed in the power system of buildings, factories or other places to distribute power from the main power supply line to various branch lines. The distribution cabinet contains a variety of electrical components, such as circuit breakers, contactors, relays, fuses, etc., to realize the functions of circuit on / off control, overload protection, short circuit protection, etc. By properly configuring and installing distribution cabinets, the safe and reliable operation of the power system can be effectively guaranteed, and flexible power supply and centralized management of different electrical equipment can be achieved. In the installation of traditional power distribution cabinets, although the bottom-entry / outlet design effectively prevents moisture from entering the cabinet through the wire inlets and outlets, avoiding short circuits or damage to electrical equipment due to moisture, this design also has some problems in actual operation. Specifically, workers need to thread the wires upwards from below, which requires them to accurately align the wire ends with the through holes at the bottom of the distribution cabinet. However, due to limited operating space and obstructed vision, errors are easily made during the threading process. If the wires are not threaded properly, the outer sheath of the wires may be torn, resulting in damage to the wire insulation layer. This not only increases the risk of electrical short circuits but may also cause safety hazards. Therefore, to address the above problems, a power distribution cabinet that is easy to install is proposed. Utility Model Content

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-8 This utility model provides a technical solution: An easy-to-install power distribution cabinet includes a distribution box assembly 1, an assembly assembly 2 installed inside the distribution box assembly 1, and a wire-threading fixing assembly 3 fixedly connected inside the assembly assembly 2. The distribution box assembly 1 includes a box body 11 with a mounting groove 12 and a cylindrical hole 13 at the lower end. A rubber duckbill valve 14 is fixedly connected inside the cylindrical hole 13. The assembly assembly 2 includes a pre-installation plate 21 with a guide groove 22, a storage groove 23 and a wire-threading port 29 on the inner side. A ramp 25 is slidably connected inside the guide groove 22 via a guide block 26. A plug post 27 is fixedly connected to the bottom end of the ramp 25. A rubber sealing ring 28 is fixedly connected to the outer side of the plug post 27. The wire-threading fixing assembly 3 includes a rubber cone 31. The rubber cone 31 and a rubber sleeve 32 are an integral structure. An annular groove 33 is opened inside the rubber sleeve 32. A rubber pull tab 34 is fixedly connected to the outer side of the rubber sleeve 32.
[0017] As a further implementation of this solution, the cylindrical hole 13 is cylindrical in shape, the rubber duckbill valve 14 extends from the lower end of the cylindrical hole 13, the inner side of the mounting groove 12 fits against the outer side of the pre-installed plate 21, the insert 27 is inserted into the inside of the cylindrical hole 13, the outer side of the rubber sealing ring 28 fits against the inner side of the cylindrical hole 13, and a gap is provided between the insert 27 and the rubber duckbill valve 14. Through the above settings, this design makes the gas discharge smoother, provides a channel for gas discharge, further enhances the stability and safety of the device, improves the stability of the seal, and at the same time, the extended design of the rubber duckbill valve 14 makes it convenient for the operator to squeeze the rubber duckbill valve 14 to allow air to pass through the cylindrical hole 13, thereby allowing the pre-installed plate 21 to be disassembled. As a further implementation of this solution, the receiving groove 23 is located at the lower end of the guide groove 22, and the guide groove 22 is connected to the receiving groove 23. A spring 24 is fixedly connected to the inner side of the guide groove 22. The upper end of the ramp 25 is provided with a slope, and half of the volume of the ramp 25 is embedded in the inner side of the guide groove 22. With the above arrangement, when squeezed, the ramp 25 moves into the receiving groove 23, which at the same time serves to store the ramp 25 and the rubber sealing ring 28. As a further implementation of this solution, the end of the rubber pull tab 34 away from the annular groove 33 is fixedly connected to the inside of the threading port 29, and the position of the rubber cone 31 near the lower end is fixedly connected to the inside of the threading port 29. Both the inner side of the rubber cone 31 and the inner side of the rubber sleeve 32 are hollow structures, and the shape of the rubber pull tab 34 is a curved structure. Through the above settings, displacement during the threading process is prevented, thereby improving the accuracy of threading and the reliability of the device.
[0018] Workflow: When installing wires inside the distribution cabinet in the distribution well environment, the assembly component 2 is separated from the distribution box component 1. The operator inserts the wire directly into the wire insertion port 29. When the wire enters the rubber cone 31, the end of the wire will expand the rubber cone 31 and the rubber sleeve 32. The rubber sleeve 32 and the rubber cone 31 are made of rubber, and they deform. The diameter of the rubber cone 31 is smaller closer to the top. This not only facilitates the installation of the wire, but also improves the connection between the rubber sleeve 32 and the wire through the deformation of the rubber cone 31. Friction, combined with the opening of the annular groove 33, further increases the stability of the connection between the rubber sleeve 32 and the wire. When the wire extends to the required length from the upper end of the wire insertion port 29, the friction between the wire and the rubber sleeve 32 prevents the wire from detaching from the rubber sleeve 32 after the wire is released. The rubber pull tab 34 undergoes a certain deformation, which prevents the rubber sleeve 32 from moving into the rubber cone 31, thus supporting the rubber sleeve 32 and the wire. At this time, the operator observes the operation through the installation groove 12, aligns the pre-installed plate 21 with the lower end of the installation groove 12, and pushes the pre-installed plate 21 upward. 1. After the ramp 25 contacts the bottom of the housing 11, the ramp 25 is compressed and slides into the guide groove 22 via the guide block 26. The ramp 25 compresses the spring 24, and at the same time, the rubber sealing ring 28 is retracted into the receiving groove 23. When the pre-installed plate 21 moves a certain distance, the rubber sealing ring 28 and the ramp 25 are reset by the elastic force of the spring 24. The insert 27 automatically aligns with the cylindrical hole 13. After the operator releases the device, the pre-installed plate 21 slides downward under the gravity of the wire and the pre-installed plate 21, and the insert 27 slides into the cylindrical hole 13. The insertion post 27 can discharge the gas inside the cylindrical hole 13. The gas is discharged through the rubber duckbill valve 14, which limits the flow of gas and prevents the insertion post 27 from detaching from the cylindrical hole 13, thus improving the stability after installation. Based on the above principles, in a space-constrained environment, the wire threading method of the device not only does not damage the wire, but also improves the stability after threading, preventing the wire from slipping out of the threading hole under its own weight, thus improving the safety of use.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
