Description

Technical Field

[0001] The invention relates to the technical field of power supply boxes, and in particular to a hollow vertical quick-access power supply box. Background Art

[0002] At present, in the process of upgrading and renovating the power distribution room, there are the following pain points:

[0003] 1. The traditional way of upgrading and transformation is to first stop the load of the users on the side to be upgraded, and then connect the copper nose (wire nose) to the power supply box to realize the user supply. However, the connection steps of the copper nose include stripping, folding, inserting and pressing, etc. The process is relatively cumbersome and the operation efficiency is low, resulting in a long power outage and inconvenience to users.

[0004] 2. When there are many users in the power distribution room, due to the large number of users actually supplied, more or larger power supply boxes are needed to meet the power supply demand, which means that the power supply of the existing power supply boxes is low. However, the construction space of most power distribution rooms is limited and cannot accommodate too much construction equipment. In addition, some community power distribution rooms are underground and have no transportation channels. Construction equipment is only transported to the station by manpower. If there are too many or heavy equipment, it will seriously affect the construction.

[0005] The existing patent CN219677786U proposes a two-input and one-output fast generator car access box. The device is large in size and has few inlet and outlet circuits. However, most of the power distribution rooms in old residential areas are located in the underground negative layer or mezzanine, with poor transportation channel conditions. At the same time, the internal space of the power distribution room is small, and the outgoing circuits of the user load are as many as twenty. The equipment in this patent cannot meet the needs of on-site use. Summary of the invention

[0041] (III) Beneficial effects

[0042] The beneficial effects of the present invention are:

[0043] The second copper busbar is connected to the main busbar and the quick-insert mechanism of the circuit breaker mechanism, and the quick-insert mechanism is connected to the circuit breaker mechanism to form a vertical frame connection system, which greatly improves the overall structural strength of the equipment. Secondly, the vertical frame connection system enhances the connection strength of the equipment inside the power supply box, which can effectively resist electric force, thereby extending the service life of the second copper busbar and ensuring the normal operation of the circuit.

[0044] The front panel and the rear panel of the shell are both provided with quick-insertion mechanisms, and the left panel and the right panel of the shell are both provided with circuit breaker mechanisms, that is, the front panel, the rear panel, the left panel and the right panel are all provided with components. Compared with the traditional power supply box which only provides components on the front panel and the rear panel, the power supply box of the present invention improves the integration of the equipment in a smaller volume. The traditional power supply box is generally a one-input and two-output structure, and the power supply box of the present invention is a one-input and seven-output structure, which greatly increases the number of output sockets of the power supply box, so that one power supply box can be adapted to seven groups of power supply, reducing the power supply pressure of the distribution room. The internal structure of the power supply box of the present invention is more compact and occupies less space; the number of inlet and outlet line circuits is several times more than that of the traditional power supply box, and the weight is lighter under the same power supply. The small-volume, multi-circuit, highly integrated power supply box of the present invention can meet more power supply needs.

[0045] There are heat dissipation holes on the bottom plate of the shell and the side plates of the top cover, so that the airflow is sucked in through the bottom plate and rises vertically until it collides with the bottom of the top cover. The airflow diverges horizontally and is discharged through the heat dissipation holes on the four side plates of the top cover, forming a T-shaped air duct, which brings out the internal heat of the power supply box and achieves cooling. The internal components of the power supply box are arranged close to the six plates of the shell, and the components are directly cooled by heat conduction of each plate. The fan blows air to the bottom plate, and with the vertical structure of the power supply box, the airflow of the T-shaped air duct can efficiently further discharge the internal heat of the power supply box and achieve secondary cooling.

[0046] The vertical hollow connector is suspended in the shell by insulators at the upper and lower ends. The main busbar and multiple second copper busbars form a trunk and branch structure, so that the vertical hollow connector forms a vertical hollow structure in the shell, which is convenient for cooling by the T-shaped air duct and electrical connection of the copper busbar.

[0071] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0072] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0073] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0074] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] See also Figures 1 to 4The present invention provides a hollow vertical quick-access power supply box, which includes a shell 1, a quick-insertion mechanism 2, a circuit breaker mechanism 3 and a vertical hollow connector 4; heat dissipation holes 11 are provided on the bottom plate and the side plates of the top cover of the shell 1 (the heat dissipation holes 11 on the bottom plate are not shown in the figure), and optionally, shutters are provided on the left and right plates of the shell 1 to further enhance the heat dissipation performance of the power supply box; the front and rear panels of the shell 1 are provided with quick-insertion mechanisms 2; the left and right plates of the shell 1 are provided with circuit breaker mechanisms 3; the vertical hollow connector 4 is built into the shell 1; the vertical hollow The connector 4 includes a plurality of insulators 41, a plurality of main busbars 42 arranged vertically and in parallel, and a plurality of curved second copper bar groups 43; adjacent main busbars 42 are connected by insulators 41, and are connected to the housing 1 by insulators 41; one end of the second copper bar group 43 is connected to the main busbar 42, and the other end is connected to the circuit breaker mechanism 3; a plurality of second copper bar groups 43 are arranged on both end surfaces of the main busbar 42; the quick-insert mechanism 2 is connected to the circuit breaker mechanism 3; wherein the projections of the plurality of second copper bars 431 of the second copper bar group 43 on the top surface of the bottom plate overlap, and a ventilation duct 46 is formed between adjacent second copper bar groups 43.

[0076] The quick-plug mechanism 2 is a quick-plug structure, which is provided with a plurality of sockets 21. Compared with the connection method of the copper nose of the plug, the present invention adopts the method of directly plugging the socket 21 with the external plug for electrical connection, which greatly simplifies the wiring process, improves the working efficiency, and shortens the power outage time of the user.

[0077] The outgoing line circuit of the traditional power supply box is not equipped with a circuit protection device, and the safety is low. The outgoing line circuit of the present invention is equipped with a protection switch, that is, a circuit breaker mechanism 3, which can cut off the power when the circuit is abnormal, thereby improving the safety of electricity use on site.

[0078] The second copper bar group 43 is connected to the main busbar 42 and the circuit breaker mechanism 3, and the quick-insert mechanism 2 is connected to the circuit breaker mechanism 3 to form a vertical frame connection system, which greatly improves the overall structural strength of the equipment. Secondly, there is a certain electric force between the adjacent second copper bars 431, and when the circuit is short-circuited, the current can reach 10-30KA. The electric force generated by the short circuit is large, which is easy to damage the second copper bar 431. In this embodiment, when a short circuit occurs, the electric force borne by the middle phase is the largest. When the short-circuit current is 30kA, the electric force borne by the middle phase on the vertical hollow connector 4 is 3932.4N, and the deflection change of the middle phase copper bar is 0.149mm. The middle phase copper bar will not cause the electrical clearance between other adjacent phases to be less than the standard requirement due to the action of the electric force. The internal structure of the power supply box of the present invention is more compact and occupies less space; the number of inlet and outlet line loops is several times more than that of the traditional power supply box, and the weight is lighter under the same power supply. The small-volume, multi-circuit, highly integrated power supply box of the present invention can meet more supply needs. The vertical frame connection system of the present invention enhances the connection strength of the internal equipment of the power supply box, and can effectively resist the electric force, thereby extending the service life of the second copper busbar 431 and ensuring the normal operation of the circuit.

[0079] The front panel and the rear panel of the shell 1 are both provided with a quick-insert mechanism 2, and the left panel and the right panel of the shell 1 are both provided with a circuit breaker mechanism 3, that is, the front panel, the rear panel, the left panel and the right panel are all provided with components. Compared with the traditional power supply box in which components are only arranged on the front panel and the rear panel, the power supply box of the present invention improves the integration of the equipment in a smaller volume. The traditional power supply box is generally a one-input and two-output structure, that is, a group of power lines enter and two groups of sockets are output with power supply. The power supply box of the present invention is a one-input and seven-output structure, which greatly increases the number of output sockets of the power supply box, so that one power supply box can be adapted to seven groups of power supply, reducing the power supply pressure of the distribution room. The internal structure of the power supply box of the present invention is more compact and occupies less space; the number of input and output line circuits is several times more than that of the traditional power supply box, and the weight is lighter under the same power supply. The small-volume, multi-circuit, highly integrated power supply box of the present invention can meet more power supply needs.

[0080] See also Figure 5 , heat dissipation holes 11 are provided on the bottom plate of the shell 1 and the side plates of the top cover, so that the airflow is sucked in through the bottom plate and then rises vertically until it collides with the bottom of the top cover. The airflow diverges horizontally and is discharged through the heat dissipation holes 11 on the four side plates of the top cover, forming a T-shaped air duct, which brings out the internal heat of the power supply box and achieves cooling. The internal components of the power supply box are arranged close to the six plates of the shell 1, and the components are directly cooled by heat conduction of each plate. The fan is used to blow air to the bottom plate, and combined with the vertical structure of the power supply box, the airflow of the T-shaped air duct can further discharge the internal heat of the power supply box efficiently, achieving secondary cooling.

[0081] The vertical hollow connector 4 is suspended in the shell 1 by insulators 41 at the upper and lower ends. The main busbar 42 and multiple second copper busbar groups 43 form a trunk and branch structure, so that the vertical hollow connector 4 forms a vertical hollow structure in the shell 1, which is convenient for cooling the T-shaped air duct and electrical connection of the copper busbar.

[0082] The existing power supply box usually only arranges components on the front panel and the back panel, but it is difficult to arrange components on the left panel and the right panel. This is because the copper busbars of the existing power supply box are planar structures, straight and straight. When components are arranged on all four sides, the copper busbars of the front and rear panels and the copper busbars of the left and right side panels will interfere with each other, resulting in the inability to connect the copper busbars. The vertical hollow connector 4 of the present invention is provided with a second copper busbar group 43 on both end surfaces of the main busbar 42. The second copper busbar groups 43 on both sides are connected to the circuit breaker mechanisms 3 on both sides to form a vertical frame connection system similar to a cage. The copper busbars of the vertical hollow connector 4 are drawn out from the main busbar 42, effectively avoiding the interference of the copper busbar wiring, thereby realizing the arrangement of components on the four sides of the power supply box. In addition, the vertical hollow connector 4 adopts a modular design, that is, the vertical hollow connector 4 and the housing 1 are modularly installed, which makes the disassembly and assembly of the vertical hollow connector 4 convenient, and optimizes the disassembly and assembly process of the power supply box.

[0083] Further, the second copper bar group 43 is in a curved shape; the second copper bar group 43 includes a plurality of second copper bars 431 arranged one by one on a plurality of main busbars 42; the projections of the plurality of second copper bars 431 on the same main busbar 42 on the top surface of the bottom plate overlap, and a ventilation duct 46 is formed between adjacent second copper bars 431 of the same second copper bar group 43. Specifically, the second copper bar group 43 is arranged in a curved shape, and the curved shape includes but is not limited to an L-shape, a concave shape, a convex shape, an arc shape, an S-shape, and combinations thereof. The curved second copper bar group 43 effectively increases the contact area between the second copper bar group 43 and the T-shaped air duct, thereby increasing the heat dissipation surface of the vertical hollow connector 4; a ventilation duct 46 is formed between adjacent second copper bar groups 43. Since a plurality of second copper bars 431 are arranged vertically and the number is relatively large, if the plurality of second copper bars 431 are arranged in a disorderly manner, it is difficult to ensure effective heat dissipation of the plurality of second copper bars 431 above the shell 1, which poses a safety hazard. Therefore, the present invention forms a ventilation duct 46 between adjacent second copper bars 431 of the same second copper bar group 43, and further forms a ventilation duct 46 inside the T-shaped air duct, so that the projections of the plurality of second copper bars 431 on the same main busbar 42 on the top surface of the bottom plate overlap, thereby effectively bringing the heat of the plurality of second copper bars 431 on the upper part out of the shell 1, thereby improving the heat dissipation performance of the power supply box. Compared with the multiple groups of copper bars arranged in a traditional planar manner, the ventilation duct 46 further enhances the heat dissipation surface of the vertical hollow connector 4, improves the heat dissipation performance of the vertical hollow connector 4, and improves the reliability of the use of a small-volume and highly integrated power supply box.

[0084] like Figures 4 to 7 As shown, a plurality of second copper bars 431 are arranged in a vertical array on the main busbar 42; along a single horizontal direction, the projections of the plurality of second copper bar groups 43 on the right side plate end surface are arranged alternately in sequence. Figure 4 Taking the orientation shown as an example, from left to right, a primary main busbar, a secondary main busbar and a tertiary main busbar are correspondingly arranged, and the second copper bar group 43 is correspondingly arranged from left to right with a primary copper bar, a secondary copper bar and a tertiary copper bar, the primary copper bar is fixed on the primary main busbar by screws, the secondary copper bar is fixed on the secondary main busbar by screws, and the tertiary copper bar is fixed on the tertiary main busbar by screws, and the installation height of the primary copper bar, the secondary copper bar and the tertiary copper bar is increased from bottom to top. In other words, in the projection on the right side plate end face, between two adjacent primary copper bars on the primary main busbar, a secondary copper bar of the secondary main busbar and a tertiary copper bar of the tertiary main busbar are arranged. By staggering the projections of multiple second copper bar groups 43 on the right side plate end face in sequence, the spacing between two adjacent second copper bars 431 on a single main busbar 42 is increased, thereby reducing the electric force between a pair of adjacent second copper bars 431, and further improving the structural strength of the vertical hollow connector 4. At the same time, multiple main busbars 42 are arranged in parallel, and there is a certain distance between adjacent main busbars 42, so the electric force between the first-level copper busbar, the second-level copper busbar and the third-level copper busbar in the horizontal direction is further reduced. The spatial layout is reasonable, and the reliability of the circuit is further improved.

[0085] The primary busbar, secondary busbar and tertiary busbar are arranged vertically in the length direction, and the second copper busbar group 43 is arranged vertically in the width direction. The heat dissipation of the copper busbars in the upper cabinet is in the optimal position.

[0086] Furthermore, the vertical hollow connector 4 also includes a branch busbar 44 and a current transformer 45 mounted on the branch busbar 44; one end of the branch busbar 44 is connected to the main busbar 42, and the other end is connected to the outlet 31 of the circuit breaker mechanism 3; the second copper busbar 431 is connected to the inlet 32 ​​of the circuit breaker mechanism 3; along the horizontal single direction, the projections of the branch busbars 44 corresponding to the multiple main busbars 42 on the right side plate end face are staggered in sequence. Specifically, the current transformer 45 generates secondary side current by sensing the current on the branch busbar 44, which is used to provide current metering data to the smart meter 17 inside the device, so as to achieve the purpose of monitoring the current at the outlet 31. Similarly, the projections of the branch busbars 44 corresponding to the multiple main busbars 42 on the right side plate end face are staggered in sequence, which effectively reduces the electric force between the multiple branch busbars 44, improves the structural strength of the vertical hollow connector 4, and enables the vertical hollow connector 4 to adapt to the power supply box with a larger power supply demand.

[0087] In this embodiment, Figure 4As shown, the free end of the branch busbar 44 and the free end of the second copper busbar 431 are both provided with connection holes, which are fixed in the outlet 31 and the inlet 32 ​​by screws. The outlet 31 and the inlet 32 ​​are slot structures, which can effectively support and limit the branch busbar 44 and the second copper busbar 431, further improving the connection strength of the vertical hollow connector 4 and more effectively coping with the generation of electric force.

[0088] Secondly, the current transformer 45 is a load power source, so that the current transformer 45 can be used as a power supply to supply the load in need in the device, thereby improving the flexibility of circuit layout.

[0089] See also Figure 8 The quick-insert mechanism 2 includes multiple sockets 21 and multiple indicator lights 22 respectively installed on the front panel and the rear panel, and a first copper bar group 23, multiple incoming wires 25 and multiple third copper bar groups 24 connected to the multiple sockets 21; the first copper bar group 23 is connected to the neutral wire 33 on the circuit breaker mechanism 3; the incoming wires 25 are connected to the outlets 31 of the circuit breaker mechanism 3 in one-to-one correspondence; the third copper bar group 24 is connected to the incoming wire 32 of the circuit breaker mechanism 3; the indicator light 22 is electrically connected to the circuit breaker mechanism 3. The indicator light 22 can connect the wire to the wiring terminal, and the other end of the wire can be crimped to the OT terminal, and connected to a certain pile head of the circuit breaker mechanism 3 by bolts. The indicator light 22 monitors the connected circuit by turning on and off. When it is on, it means that the corresponding circuit has a circuit, and when it is off, it means that the corresponding circuit has no circuit, thereby improving the intelligence of the circuit.

[0090] Specifically, a group of sockets 21 corresponds to multiple plug boards, and multiple plug boards are connected to A / B / C / N incoming or outgoing lines. One group of sockets 21 is the incoming socket for external plugs, that is, "one in"; the remaining groups of sockets 21 are output sockets, used for power distribution room supply, that is, "seven out". Figure 8 Taking the front panel shown as an example, the first copper bar group 23 is connected to the neutral line bar 33, the three third copper bar groups 24 are connected to the incoming line port 32 of the circuit breaker mechanism 3, and the three incoming line bars 25 are connected to the outgoing line port 31 of the circuit breaker mechanism 3, finally forming a "one in and three out" structure. Similarly, the rear panel is a "four out" structure. The front and rear panels are combined to form a "one in and seven out" structure. The copper bars in this embodiment are all connected by screws, and no or only a small amount of wire bonding is performed, which greatly simplifies the wiring process of the circuit, while improving the connection strength of the vertical hollow connector 4, and more effectively resisting electric force.

[0091] Of course, the specific copper bus layout can be flexibly adjusted according to actual conditions. The layout of components on the front panel and the rear panel, as well as the layout of components on the left panel and the right panel in this embodiment are not completely symmetrical. The present invention emphasizes that the vertical frame connection system adopted by the vertical hollow connector 4 is different from the traditional planar copper bus layout system. The vertical frame connection system is superior to the planar copper bus layout system in terms of structural strength and heat dissipation performance.

[0092] In addition, a screw is provided on one side of the socket 21 facing the inside of the housing 1; the screw is connected to the incoming line bar 25 via a temperature measuring nut 5. After a lot of analysis and test verification, the part from the outlet 31 of the circuit breaker mechanism 3 at the top of the equipment to the socket 21 is a potential risk point for temperature rise, so the temperature measuring nut 5 is provided there in this embodiment.

[0093] Compared with the way that the first copper bar group 23 and the second copper bar 431 are connected by screws, the connection method of the temperature measuring nut 5 and the screw rod can not only realize the connection between the two, but also monitor the temperature of the second copper bar 431. Of course, the temperature measuring nut 5 can also be set in the first copper bar group 23 and the third copper bar group 24. The temperature measuring nut 5 can warn of abnormal temperature rise at the contact point, avoid accidents such as fire and short circuit caused by temperature rise of the equipment, and improve the safety of the equipment.

[0094] like Fig. 9 and Fig.10 As shown, the plug of the external power supply is plugged into the A / B / C / N incoming socket, i.e., "one in"; the incoming line bus 25 is electrically connected to the outlet 31; the outlet 31 is electrically connected to the branch bus 44, and the branch bus 44 is further connected to multiple second copper bus groups 43; multiple second copper bus groups 43 are correspondingly connected to multiple groups of output sockets 21, Fig.10 The three black dots represent the omitted multiple outgoing circuit breakers. In this embodiment, there are seven outgoing circuit breakers, i.e., "seven outs". The circuit breaker mechanism 3 then conducts the corresponding multiple A / B / C / N outgoing sockets through the third copper bar 24. Finally, the power supply box can be equipped with components on four sides and has efficient heat dissipation performance, realizing a multi-circuit small-volume vertical power supply box.

[0095] See also Fig.11The top cover is provided with a touch screen 16, a smart meter 17 and a GPS circuit board 18 that are connected to the remote host computer in communication; the touch screen 16 can communicate wirelessly with the temperature measuring nut 5; the vertical hollow connector 4 is electrically connected to the smart meter 17. The touch screen 16 is embedded in the top cover, and the touch screen 16 has a processing module that can decode the temperature signal wirelessly transmitted from the temperature measuring nut 5, output the temperature data, and display it on the human-machine interface; at the same time, the signal can be transmitted to the remote host computer. The smart meter 17 is also embedded in the top cover. It integrates metering functions such as current, voltage and power, and can reflect the voltage data of the monitoring point inside the equipment in real time, and provide current data together with the current transformer 45. Traditional pointer-type meters need to be configured with different meters according to the actual measured parameters such as voltage, current and power. There are many meters and a large installation space is required; the smart meter 17 is an intelligent instrument that integrates data such as voltage, current and power, and efficiently utilizes the equipment space to further reduce the volume of the power supply box. The GPS circuit board 18 is fastened to the inner side of the top cover by screws. It uses a wireless transmission GPS positioning module to transmit positioning data to a remote host computer via satellite in real time. Through the touch screen 16, the smart meter 17 and the GPS circuit board 18, the status of the device can be monitored in real time during normal operation of the device, realizing unattended operation.

[0096] It should be noted that during the transformation of medium and low voltage in the distribution room, the emergency power supply equipment needs to work for a long time for one or two weeks. How to ensure the safety of emergency projects is particularly important. At present, the safety of on-site emergency power supply is ensured by 24-hour on-duty personnel. Since the on-site on-duty personnel are usually not professional operation and maintenance personnel, they cannot make predictions about failures and risks in the operation process in the first time. It is often only after the accident occurs that the relevant operation and maintenance personnel can be effectively notified to deal with it. How to prevent accidents before they happen is a thorny problem facing the current emergency power supply. The present invention uses a touch screen 16 to perform temperature alarm, uses a smart meter 17 to monitor and predict circuit abnormality risks, and uses a GPS circuit board 18 to perform GPS positioning. In addition, when the circuit is abnormal, the circuit breaker mechanism 3 can automatically cut off the power supply, which greatly improves the intelligence of the power supply box and realizes unattended operation.

[0097] Secondly, the socket 21 is provided with a locking device; when the socket 21 is energized, the locking device can prevent the preset plug from being inserted into the socket 21; when the plug and the socket 21 are plugged in and energized, the locking device can prevent the plug from being pulled out of the socket 21. The preset plug is the plug of the external power source. The locking device can effectively prevent the socket 21 from being engaged or pulled out of the plug when energized, prevent personnel from illegally operating the energized device, prevent equipment damage and personal safety accidents, and improve the safety of equipment use.

[0098] In the first embodiment, if Fig.12As shown, the housing 1 includes a bracket 15, a U-shaped support bar 12, a U-shaped mounting bar 13 and an L-shaped mounting frame 14; the top and bottom ends of the bracket 15 are detachably connected to a pair of U-shaped support bars 12, which can be connected by screws; the two ends of the U-shaped mounting bar 13 are connected to the folded edges of a pair of U-shaped support bars 12, respectively; the projection of the U-shaped mounting bar 13 on the rear panel is Z-shaped; the end face of the U-shaped mounting bar 13 is connected to the circuit breaker mechanism 3, and can vertically support the circuit breaker mechanism 3; the L-shaped mounting frame 14 is arranged at the bottom of the end face of the bracket 15; the L-shaped mounting frame 14 is connected to the vertical hollow connector 4. Specifically, the U-shaped support bar 12 and the U-shaped mounting bar 13 are U-shaped structures, so that the end face and the side panels on both sides of the U-shaped bar can be used for connection and support and limiting, wherein the L-shaped mounting frame 14 is connected to the insulator 41, which improves the connection strength of the vertical hollow connector 4. The projection of the U-shaped mounting bar 13 on the rear panel is Z-shaped, so that the U-shaped mounting bar 13 can vertically support the circuit breaker mechanism 3, improve the installation stability of the circuit breaker mechanism 3, and further improve the connection strength of the vertical hollow connector 4. Through the cage-type vertical hollow connector 4 and the U-shaped bar structure, the entire electrical circuit is strengthened, making the vertical frame connection system stronger and more effective in resisting electric force.

[0099] In the second embodiment, if Fig.13 As shown, the housing 1 includes a bracket 15, a frame 9 and a connecting plate 91; the top and bottom ends of the bracket 15 are detachably connected to a pair of frames 9 in a one-to-one correspondence; the two end folds of the connecting plate 91 are connected to the folds of a pair of frames 9 in a one-to-one correspondence; the end face of the connecting plate 91 is connected to the circuit breaker mechanism 3; the other end face of the connecting plate 91 is clamped with the vertical hollow connector 4. The components of the second embodiment and the first embodiment are all U-shaped structures (folded edge structures), which can effectively improve the connection strength of the vertical frame connection system. In the first and second embodiments, the other components of the housing 1 except the bracket 15 can be pre-assembled with the vertical hollow connector 4. The pre-assembled vertical hollow connector 4 can be stably placed vertically on a base surface, which is convenient for subsequent assembly with the bracket 15, optimizing the installation process, and reducing the labor intensity of on-site installation.

[0100] Compared with the first embodiment, the second embodiment has only a pair of frames 9 and a pair of connecting plates 91, a total of four components, which simplifies the installation structure of the device; at the same time, the reduction in the number of components improves the installation accuracy, that is, the docking accuracy of the pre-assembled vertical hollow connector 4 and the bracket 15 is improved, which reduces the requirements for the manufacturing accuracy and docking accuracy of each component. Figure 6 and Figure 7As shown in the figure, the vertical hollow connector 4, a pair of circuit breaker mechanisms 3, a pair of frames 9 and a pair of connecting plates 91 are pre-assembled and can be disassembled and assembled as a module, namely a vertical hollow module, which simplifies the disassembly and assembly process of the power supply box. More importantly, the quick-insertion mechanism 2 is set on the front and rear panels, which occupies very little internal space of the shell 1. When installed in conjunction with the vertical hollow module, the volume of the shell 1 can be made very small, realizing a small-volume, multi-circuit, highly integrated power supply box.

[0101] Alternatively, see Fig.14 A buckled or hinged protective plate 8 is provided at the front and rear panels and the left and right side panels of the housing 1. While playing a protective role, it is also easy to disassemble, so as to facilitate the operation of the components on the front and rear panels and the left and right side panels. A plurality of lifting ears 7 can also be provided at the top of the housing 1, and a plurality of handles 19 can be provided on the side of the housing 1 to facilitate the transportation of the power supply box.

[0102] Furthermore, the power supply box also includes casters 6 and shock-absorbing rubber pads 61; multiple casters 6 are arranged at the bottom of the base plate; and shock-absorbing rubber pads 61 are arranged between the casters 6 and the base plate. The casters 6 can be universal wheels for easy steering, with foot-operated lock plates to flexibly move and fix the power supply box. The shock-absorbing rubber pads 61 can effectively buffer the electric power, further protect the vertical hollow connector 4, extend the service life of the vertical hollow connector 4, and improve the reliability of the power supply box with components arranged on all four sides.

[0103] It should be understood that the above description of the specific embodiments of the present invention is only for illustrating the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, but the present invention is not limited to the above specific implementation methods.
