[0002] Cable branch boxes are key equipment in power distribution network systems used for cable branching and connection. Their main function is to distribute the electrical energy of the main cable to multiple branch cables or to realize electrical connections between different lines. They construct current transmission channels through internal busbars, cable joints, and other components, while relying on insulation structures and protective shells to ensure safe operation. They are indispensable node equipment in the cable transformation of distribution networks.

[0003] Under normal operating conditions, the power supply from a substation passes through the distribution room, cable branch boxes, and meter boxes before being delivered to various users. However, when a circuit fault occurs or maintenance is carried out at the substation, a power outage will occur, causing inconvenience to users. In particular, when users are medical facilities, public building escape systems, or transportation hubs, a sudden power outage may have a serious impact that endangers people's lives.

[0004] Emergency power supplies are backup power supply devices that can be quickly put into operation when the main power source (such as the power grid) is suddenly interrupted, malfunctions, or experiences voltage abnormalities, providing continuous power to critical equipment or locations. Their core function is to ensure the continuous operation of scenarios where "power outages are not an option" (such as life safety, core business operations, and public order).

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: Figures 1 to 3As shown, an emergency power module for a cable branch box includes a module housing 1, four emergency power quick plugs located above the module housing 1, and three contacts located at the bottom of the module housing 1. The four emergency power plugs are emergency power quick plug one 2, emergency power quick plug two 3, emergency power quick plug three 4, and emergency power quick plug four 5. The three contacts are contact one 6, contact two 7, and contact three 8. The lower end of emergency power quick plug one 2 is electrically connected to contact one 6, the lower end of emergency power quick plug two 3 is electrically connected to contact two 7, and the lower end of emergency power quick plug three 4 is electrically connected to contact three 8. A grounding connection structure is also provided on the module housing 1 located at the lower end of emergency power quick plug four 5. The lower end of emergency power quick plug four 5 can be electrically connected to the grounding busbar in the cable branch box through the grounding connection structure. The grounding busbar is connected to the ground wire. The emergency power supply quick-connect plug is a female plug, while the cable plug in the emergency power supply is a male plug. The upper end of emergency power supply quick-connect plug 1 (2) connects to the A-phase cable (not shown in the diagram) of the emergency power supply via a plug-in structure. The upper end of emergency power supply quick-connect plug 2 (3) connects to the B-phase cable (not shown in the diagram) of the emergency power supply via a plug-in structure. The upper end of emergency power supply quick-connect plug 3 (4) connects to the C-phase cable (not shown in the diagram) of the emergency power supply via a plug-in structure. The upper end of emergency power supply quick-connect plug 4 (5) connects to the neutral cable of the emergency power supply via a plug-in structure. The cable branch box is equipped with busbar 1 (9), busbar 2 (10), and busbar 3 (11). After the emergency power supply module is installed in the cable branch box, it is electrically connected to busbar 1 (9), busbar 2 (10), and busbar 3 (11) via contacts 1 (6), 2 (7), and 3 (8), respectively. In addition to the emergency power supply module in this embodiment, busbar copper busbar 19, busbar copper busbar 20 and busbar copper busbar 31 are also equipped with other electrical components 12, such as circuit breaker sockets and circuit breakers. The other electrical components 12 are also electrically connected to busbar copper busbar 19, busbar copper busbar 20 and busbar copper busbar 31 through multiple contacts at their bottom.

[0021] During normal operation, the three-phase power from the substation passes through the distribution room and is electrically connected to busbar 9, busbar 10, and busbar 31 respectively. For example, phase A of the three-phase power is electrically connected to busbar 9, phase B of the three-phase power is electrically connected to busbar 10, and phase C of the three-phase power is electrically connected to busbar 31. Then, the three-phase power is transmitted through busbar 9, busbar 2, and busbar 31 to other electrical components 12, and then delivered to users through other electrical components 12. At this time, the emergency power supply module does not work. In case of an emergency and a power outage, when an emergency power supply is needed, connect the upper end of emergency power quick-connect plug 12 to the A-phase cable of the emergency power supply via a plug-in structure; connect the upper end of emergency power quick-connect plug 23 to the B-phase cable of the emergency power supply via a plug-in structure; connect the upper end of emergency power quick-connect plug 34 to the C-phase cable of the emergency power supply via a plug-in structure; and connect the upper end of emergency power quick-connect plug 45 to the neutral cable of the emergency power supply via a plug-in structure. At this time, the three-phase power provided by the emergency power supply is transmitted to busbar 9, busbar 10, and busbar 11 respectively through emergency power quick-connect plugs 12, 23, and 34, and then to other electrical components 12, which continue to transmit the power to the user, thus enabling the emergency power supply to replace the main power supply and continue to provide power to the user. Here, the emergency power module can be installed in the cable distribution box during normal operation, but it is disconnected from the multiple cables of the emergency power supply. When the emergency power is needed, the multiple cables of the emergency power supply are then connected to the emergency power module. Alternatively, the emergency power module can be installed out of the cable distribution box initially, and then electrically connected to the emergency power supply when needed.

[0022] Through the above structural design, this embodiment enables the emergency power module to connect with the emergency power supply in the event of a sudden power outage at the substation. The emergency power supply can temporarily replace the main power supply to continue supplying power to the user, thereby avoiding accidents, property damage, or disorder caused by power outages.

[0023] like Figure 4 As shown, the module housing 1 includes a mounting cover 111 located at the top and a base 112 located at the bottom. The mounting cover 111 and the base 112 are connected by screws. During assembly, the four emergency power quick plugs, three contacts, and the grounding connection structure are first installed on the base 112. After installation, the mounting cover 111 is then placed on the base 112 to connect them. In this way, the module housing 1 is designed as a two-part disassembly structure, which facilitates the assembly of the entire module.

[0024] like Figure 5 and Figure 6 As shown, a connecting copper busbar 13 is provided between the emergency power quick plug 2 and the contact 6. The connecting copper busbar 13 is fixed to the base 112 by screw 2 14. All three contacts are inverted U-shaped, and all four emergency power quick plugs are cylindrical. Screw 3 15 is screwed into the threaded hole at the lower end of the emergency power quick plug 2 after passing through the bottom of the inverted U-shape of the contact 6 and the connecting copper busbar 13, thereby electrically connecting the lower end of the emergency power quick plug 2 to the contact 6. The remaining two contacts and the emergency power quick-connect plug are connected using the same mounting structure. Specifically, connecting copper busbars two and three are respectively installed between emergency power quick-connect plug two (3) and contact two (7), and between emergency power quick-connect plug three (4) and contact three (8). First, connecting copper busbars two and three are fixed to the base using screws four and five, respectively. Then, screw six passes through the inverted U-shaped bottom of contact two and the connecting copper busbar two, and is screwed into the threaded hole at the lower end of emergency power quick-connect plug two, thus electrically connecting the lower end of emergency power quick-connect plug two to contact two. Similarly, screw seven passes through the inverted U-shaped bottom of contact three and the connecting copper busbar three, and is screwed into the threaded hole at the lower end of emergency power quick-connect plug three, thus electrically connecting the lower end of emergency power quick-connect plug three to contact three. In this embodiment, other conductive metal sheets can also be used for the connecting copper busbars.

[0025] like Figure 7 As shown, the grounding connection structure includes a connecting copper busbar 16 located below the emergency power quick plug 45. The connecting copper busbar 16 is locked to the base 112 by screw 8 17. A screw 9 18 passes through one end of the connecting copper busbar 16 and is screwed into the threaded hole at the lower end of the emergency power quick plug 45, thus electrically connecting the lower end of the emergency power quick plug 45 to the connecting copper busbar 16. The other end of the connecting copper busbar 16 is the grounding connection end. A screw 10 19 connects the grounding busbar 20 in the cable branch box to the other end of the connecting copper busbar 16, ultimately allowing the lower end of the emergency power quick plug 45 to be electrically connected to the grounding busbar in the cable branch box through the grounding connection structure. One end of the mounting cover 111 is an open port 21, facilitating the insertion of the grounding busbar 20. A through hole 22 is also provided on the top of the mounting cover 111, allowing installers to insert tools such as screwdrivers through the through hole 22 to tighten the screw 10 19.

[0026] like Figures 6 to 8As shown, multiple arc-resistant cylindrical portions 1121 made of insulating material are also provided on the bottom of the base 112. The heads of the screws used to connect the copper busbar and the base are all provided with arc-resistant cylindrical portions 1121, which prevents the current from forming an arc between the screws and improves safety. In this embodiment, the heads of screws 14 (connecting copper busbar 13 and base 112), 14 (connecting copper busbar 2 and base 112), 15 (connecting copper busbar 3 and base 112), and 17 (connecting copper busbar 4 and base 112) are all provided with arc-resistant cylindrical portions 1121.

[0027] like Figure 1 As shown, three LED indicator lights are also provided on the top of the mounting cover 111: indicator light 23, indicator light 24, and indicator light 25. Indicator light 23 is electrically connected to emergency power quick plug 2, indicator light 24 is electrically connected to emergency power quick plug 3, and indicator light 25 is electrically connected to emergency power quick plug 4. When the emergency power quick plug is powered on, the corresponding indicator light will also light up, making it easy to determine whether the three-phase power of the emergency power supply is connected.

[0028] When the emergency power module is installed in the cable distribution box during normal operation, it is energized due to the presence of the main power supply. To prevent accidental contact with the emergency power quick-connect plug and the risk of electric shock, therefore, if... Figure 9 As shown, a flip cover 26 is also provided on the mounting cover 111. The flip cover 26 can cover the emergency power quick plug, thereby preventing staff from accidentally touching the emergency power quick plug and causing electric shock risk.

[0029] like Figure 10 As shown, the flip cover 26 includes an inverted U-shaped cover 261 and a baffle 262 disposed on one side of the inverted U-shaped cover 261. The other side of the inverted U-shaped cover 261 is open. A hinge structure 27 is disposed on the bottom of the baffle 262. Multiple hinge structures 27 are provided; in this embodiment, three are provided. Figure 11As shown, hinge structures 28 are provided on both sides of the top of the mounting cover 111. The flip cover 26 can be connected to the hinge structure 28 on one side of the top of the mounting cover 111 via hinge structure 27, so that the flip cover 26 is hinged to one side of the top of the mounting cover 111. Here, the flip cover 26 can also be connected to the hinge structure 28 on the other side of the top of the mounting cover 111 via hinge structure 27, so that the flip cover 26 is hinged to the other side of the top of the mounting cover 111. This detachable hinge structure design is to accommodate different installation positions of the emergency power module in the cable branch box, such as... Figure 3 As shown, when other electrical components 12 are installed on the right side of the emergency power module, the hinge of the flip cover 26 can be hinged to the right side of the emergency power module, allowing the flip cover 26 to be flipped open from the left side of the emergency power module. When other electrical components 12 are installed on the left side of the emergency power module, the flip cover can be pulled out from the right side of the emergency power module, and then the hinge of the flip cover 26 can be hinged to the left side of the emergency power module, allowing the flip cover 26 to be flipped open from the right side of the emergency power module. This design allows this embodiment to adapt to different installation conditions, improving its versatility and practicality.

[0030] like Figures 12 to 14 As shown, the first hinge structure 27 includes multiple connecting pieces 271 with one end disposed on the bottom of the baffle 262. The other ends of the multiple connecting pieces 271 are connected by a pivot 272. In this embodiment, a total of three connecting pieces 271 are provided. The second hinge structure 28 includes a groove 281 disposed on one side of the top of the mounting cover 111. One side of the groove 281 is open. Multiple stops 282 are provided on the open side of the groove 281, thereby forming multiple gaps 283 on the open side of the groove 281. In this embodiment, a total of three gaps 283 are formed. When hinged, the pivot 272 of the first hinge structure 27 is engaged in the groove 281 of the second hinge structure 28, and the multiple connecting pieces 271 are inserted into the multiple gaps 283, thereby hinged the flip cover 26 and the mounting cover 111 together. After hinge, the two sides of the rotating shaft 272 contact the inner side of the stop block 282 and the inner side of the groove 281 respectively. In order to make the rotating shaft rotate more smoothly, the inner side of the stop block 282 and the inner side of the groove 281 can be set into an arc shape, and the arc of the arc matches the arc of the rotating shaft.

[0031] like Figure 9 As shown, lead-sealed screw holes are provided at both ends of the inverted U-shaped cover 261. Lead-sealed screws 29 are passed through the lead-sealed screw holes and tightened onto the mounting cover 111, thereby fixing the flip cover 26 onto the mounting cover 111. By providing lead-sealed screws, it is possible to further prevent workers from accidentally opening the flip cover and avoid electric shock accidents.

[0032] In summary, through the aforementioned structural design, this utility model enables the emergency power supply module to connect to an emergency power source in the event of a sudden power outage at a substation. This emergency power source temporarily replaces the main power supply to continue providing power to users, thus preventing accidents, property damage, or disruption caused by power outages. The modular housing is designed as a two-part, detachable structure, facilitating the assembly of the entire module. The anti-arc cylindrical section prevents current from forming an arc between the screws. The detachable hinge structure between the flip cover and the mounting cover allows the flip cover to be hinged to the left or right side of the top of the mounting cover, adapting to different installation conditions and improving the utility and practicality of this utility model.
