[0002] Busbar trunk distribution devices, or bus ducts, are widely used in the power distribution systems of low-voltage complete switchgear and control equipment. They are used to replace cables and wires to distribute power to electrical equipment loads such as high-rise buildings, factories, IDC (Internet Data Center) rooms, and PDUs (Power Distribution Units). Existing bus ducts are a new type of conductor that uses copper or aluminum as a conductor, supported by an insulator, and then installed in a metal trough. They have become an indispensable wiring method in power systems. When the bus duct is in use, it must be connected to the electrical equipment. Among the existing methods, some use sockets and outlet boxes to draw power and output, and some use sockets to draw power. However, the existing methods and devices have a low degree of integration, lack the convenience of installation and use, and lack the reliability and safety of the connection.

[0003] [Summary of the invention]

[0004] The present invention aims to solve the above problems and provide a plug-in power supply device that can be connected to the bus duct to obtain electricity. The plug-in operation is convenient and quick, and the electric energy obtained from the bus duct can be distributed to electrical equipment in a variety of ways. It has a high degree of integration, reliable connection, and is safe to use.

[0005] To achieve the above-mentioned purpose, the present invention provides a plug-in power supply device, which is provided with a main box body, in which a plug-in power supply mechanism and a control mechanism are provided. The plug-in power supply mechanism is plugged into the bus duct to supply power, and is electrically connected to the electrical equipment through multiple power sockets or industrial electrical connectors for power output.

[0007] The bus duct is provided with a trough body with open ends and a bottom. Several insulating sheaths are arranged at intervals along the width direction in the trough body. A first conductive plate is provided in each insulating sheath. Multiple first conductive plates are arranged into a first conductive plate group. The two ends of each first conductive plate extend from the two ends of the insulating sheath.

[0008] The plug-in power-taking mechanism is arranged at an upper part of one side of the main box body, and includes a power-taking part for connecting to the bus duct and an operating part for performing power-taking operations.

[0009] The power taking part includes several second conductive plates, several insulating plates, a fixing seat and a bracket. The several second conductive plates are connected to the multiple insulating plates, and their upper ends are against the elastic conductive copper plates on one side of the insulating plates. The several second conductive plates and the elastic conductive copper plates are arranged into a second conductive plate group along the width direction of the main box body corresponding to the first conductive plate group in the bus duct.

The main body of the operating handle extends to the outside of the main box body. The output end of the connecting rod mechanism is connected to a vertical lifting rod. The upper end of the lifting rod is fixed to the bracket. Two guide columns are fixed on the bracket. The two guide columns enter the bracket upward. The bracket can move up and down along the two guide columns under the action of the lifting rod to connect or disconnect the second conductive plate group with the first conductive plate group in the bus duct to take power.

[0011] The connecting rod mechanism includes an active connecting rod and two pairs of driven connecting rods, wherein the active connecting rod has three arms, the first arm of which is hinged to the operating handle and rotates around a first pin fixed to the side wall of the connecting seat, the second arm is placed in a limiting groove at the top of the connecting seat, and the end of the third arm is hinged to the two pairs of driven connecting rods through a second pin, one end of the driven connecting rod is hinged to the third pin, and the other end of the driven connecting rod is hinged to the lifting rod of the operating part.

[0020] The following examples are provided to further explain and illustrate the present invention and do not constitute any limitation to the present invention.

[0021] Referring to Figures 1-3 , the plug-in power supply device of the present invention includes a main housing 10, a plug-in power supply mechanism 20, a control mechanism 30, and a bus duct 40. The main housing 10 houses the plug-in power supply mechanism 20, which connects to the bus duct 40 for power supply. The control mechanism 30 distributes and safely controls power transmission and output from the bus duct. The present invention will be described in more detail below with reference to the accompanying drawings.

[0022] As shown in Figures 1, 2, and 4, the main housing 10 is located below the bus duct 40 and houses the plug-in power supply mechanism 20 and control mechanism 30. In the embodiment shown in Figures 1A and 2A, several power outlets 51 for power output are located on the front of the main housing 10. In this embodiment, these power outlets 51 are concealed, located on the front panel of the main housing 10 and hidden behind a retractable cover 511. They are used to connect to terminal electrical devices such as PDUs. In another embodiment shown in Figures 1B and 2B, several industrial electrical connectors 52 for power output are located at the bottom of the main housing 10. Users can select the appropriate power outlet 51 or industrial electrical connector 52 as needed. A window 11 is provided at the top of the main housing 10, through which the upper end of the plug-in power supply mechanism 20 extends. A hole is provided on the side of the main housing 10, through which the operating handle of the plug-in power supply mechanism 20 extends.

[0023] As shown in Figures 4A and 4B, the busbar trunking 40 comprises a trunk body 41 with open ends and a bottom. The trunk body 41 is made of aluminum alloy. The open bottom of the trunk body 41 is used to connect the first conductive plate assembly 43A therein with the second conductive plate assembly 21A of the plug-in power supply mechanism 20. Several vertical partitions 411 are arranged along the width of the trunk body 41. The upper ends of the vertical partitions 411 are connected to the top of the trunk body 41. Each sidewall of each vertical partition 411 is provided with three inwardly projecting steps 4111 extending from one end to the other. An insulating sheath 42 is positioned within the cavity formed by each pair of adjacent vertical partitions 411. The insulating sheath 42 is an open-bottomed sleeve with an inwardly curved arc-shaped groove 421 at its lower end. This groove is used to accommodate the first conductive plate 43. The ends of the insulating sheath flare outward to facilitate the insertion of the second conductive plate assembly 21A of the plug-in power supply mechanism. A limit baffle 422 extending from one end to the other is connected to the edge of the arc-shaped groove 421 at the top of the insulating sheath. An outwardly protruding outer step 423 is provided on one of the outer sides of the insulating sheath, and the insulating sheath 42 is made of fire-retardant insulating material. The insulating sheath 42 is supported on the inner step 4111 of the vertical partition 411 by its outer step 423. A first conductive plate 43 is provided in each insulating sheath 42, and the upper and lower ends of the first conductive plate 43 are respectively limited by the limit baffle 422 and the arc-shaped groove 421. The first conductive plate 43 is a strip of copper plate, and its input end is electrically connected to an external power distribution device, such as a power distribution cabinet. Multiple first conductive plates 43 are arranged into a first conductive plate group 43A. One end of each first conductive plate 43 extends from the end of the slot body 41 and is connected to equipment such as a distribution cabinet. The other end of the first conductive plate 43 extends from the end of the slot body 41 to be electrically connected to another bus duct or closed by an end cover.

[0024] The bus duct 40 is connected to a plug-in power supply mechanism 20 for plugging into the bus duct to draw power, monitor the bus duct's power transmission process, and collect, transmit, and display data on the current and voltage of the bus duct's conductors. The plug-in power supply mechanism 20 is housed within the main housing 10, which is secured to the bus duct 40 via known methods such as bolts and snap-fit ​​connections.

[0025] As shown in Figures 3A to 3C, the plug-in power supply mechanism 20 is located on the upper side of the main box 10 and includes a power supply unit 21 for connecting to the bus duct and an operating unit 22 for performing power supply operations. The power supply unit 21 includes a plurality of second conductive plates 211, a plurality of insulating plates 212, a fixing seat 213, and a bracket 215. The second conductive plate 211 is a strip of conductive copper plate, the upper end of which is composed of an outward-turning inclined surface, a vertical plane turned from the inclined surface, and an arcuate surface turned from the vertical plane. The turning surface is used to increase the elasticity of the second conductive plate and the reliability of the electrical connection. The lower end of the second conductive plate 211 is L-shaped. The L-shaped connecting end of each second conductive plate 211 is fixed to the fixing base 213 fixed on the bracket 215 with a screw. The upper end of each second conductive plate 211 abuts against the elastic conductive copper plate 214 on one side of the insulating plate 212. The elastic conductive copper plate is a curved plate formed by multiple turning surfaces, and a U-shaped arc surface is provided at its upper end. The U-shaped arc surface abuts against the insulating plate 212. The curved shape of the elastic conductive copper plate helps to increase the elastic deformation of the second conductive plate 211 when plugging with the first conductive plate 43 and the close contact after plugging. The power extraction unit 21 includes several second conductive plates 211 arranged along the width of the main box 10, corresponding to the first conductive plate group 43A in the bus duct, to form a second conductive plate group 21A. The upper ends of the second conductive plate group 21A extend outside the main box 10 through the window 11 in the upper portion of the main box. The second conductive plate group 21A is inserted from the bottom of the bus duct into the first conductive plate group 43A, connecting the second conductive plate group 21A and the first conductive plate group 43A to draw power. This completes the second step of the step-by-step power extraction process.

[0026] As shown in Figures 3A to 3C and Figures 3F to 3G, the operating part 22 includes a connecting rod mechanism 221, a connecting seat 222, an operating handle 223, a lifting rod 224 and a guide column 225. The operating part 22 is connected to the lower side of the power taking part 21, and is provided with a connecting rod mechanism 221 that drives the power taking part to move up and down. The connecting rod mechanism 221 includes an active connecting rod 2211 and two pairs of driven connecting rods 2212 and 2213. Among them, the active connecting rod 2211 is a multi-arm connecting rod with three arms, the first arm 2211A of which is fixedly connected to the operating handle 223 and rotates around the first pin 2214 fixed to the side wall of the connecting seat 222. The second arm 2211B is placed in the limiting groove 2221 at the top of the connecting seat to limit the left and right movement of the active connecting rod 2211. The end of the third arm 2211C is hinged to two pairs of driven links 2212 and 2213 through a second pin 2215. Each pair of driven links 2212 and 2213 is composed of two symmetrical links in front and back. The other end of the driven link 2212 is hinged to the third pin 2216. The other end of the driven link 2213 is hinged to the lifting rod 224 of the operating part. The connecting rod mechanism 221 is connected to the connecting seat 222 fixed to the side wall of the main box body. The input end of the connecting rod mechanism 221 is connected to the operating handle 223. The main body of the operating handle 223 extends to the outside of the main box body 10. The output end of the connecting rod mechanism 221 is connected to the vertical lifting rod 224, and the upper end of the lifting rod 224 is fixed to the bracket 215. Two guide posts 225 are fixed to the bracket 215 of the power supply unit. The lower ends of the two guide posts 225 are fixed to a support plate 226 connected to the side wall of the main box body 10. The two guide posts 225 extend upward into the bracket 215. Under the action of the lifting rod 224, the bracket 215 can move up and down along the two guide posts 225, thereby connecting or disconnecting the second conductive plate group 21A with the first conductive plate group 43A in the bus duct to draw power. When the operating handle 223 is pressed or lifted, the linkage mechanism 221 pushes the lifting rod 224 up and down, connecting or disconnecting the second conductive plate group 21A of the power supply unit with the first conductive plate group 43A in the bus duct to draw power.

[0027] During step-by-step power draw, the plug-in power draw mechanism's second conductive plate group 21A is positioned below the bus duct's first conductive plate group 43A. When the plug-in power draw mechanism's operating handle 223 is pressed, the second conductive plate group 21A, driven by the linkage 221, moves upward and inserts into the bus duct's first conductive plate group 43A. This ensures that the second conductive plates 311 of the second conductive plate group 21A come into close contact with the first conductive plates 43 of the first conductive plate group 43A, creating electrical continuity. This completes the plug-in power draw mechanism 20's connection to the bus duct. To disconnect, lift the operating handle 223.

[0028] As shown in Figure 5, the control mechanism 30 includes a control unit 31, a power supply unit 32, an output unit 33, and a monitoring module 34. The monitoring module 34 integrates a switching power supply 341, a current acquisition unit 342, a voltage acquisition unit 343, a monitoring unit 344, a communication interface unit 345, and a display screen 346. The control unit 31 is a circuit breaker that distributes power to the busbar and connects and disconnects power-consuming devices to the busbar circuit, protecting the power distribution system. When a line is severely overloaded or a fault occurs, it automatically disconnects the circuit to ensure the safe use of the busbar and the step-by-step power supply device. The control unit 31 is electrically connected to the power supply unit 32 and the output unit 33, respectively. The power supply unit 32 is electrically connected to the second conductive plate assembly 21A of the power supply unit 21. The output unit 33 is electrically connected to the power socket 51 or industrial electrical connector 52. A switching power supply 341 is connected between the power supply unit 32 and the control unit 31. Connected between the control unit 31 and the output unit 33 are a current acquisition unit 342 and a voltage acquisition unit 343. These are current sensors and voltage sensors, respectively, electrically connected to the power extraction portion 21 of the plug-in power extraction mechanism, for real-time data collection of the current and voltage of the power extraction unit 32. The current acquisition unit 342 and the voltage acquisition unit 343 are also connected to a monitoring unit 344, a single-chip microcomputer, which is connected to the switching power supply 341, the communication interface unit 345, and the display screen 346. The monitoring unit 344 analyzes and processes the monitored current and voltage data, converting them into data such as power, energy, and temperature, and then sends signals to the switching power supply 341 and the communication interface unit 345 for display on the display screen 346.

[0029] Thus, the plug-in power supply device of the present invention is provided with a plug-in power supply mechanism that can draw power in steps. It can be quickly connected to the bus duct through the clamping mechanism, and the plug-in power supply mechanism can be operated to draw power from the bus duct and safely distribute the obtained electric energy to the electrical equipment. It can also effectively and safely control the power drawing and output process, thereby providing a safe and efficient power distribution system for electrical equipment such as PDU.
