Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a power manager. Background Technology

[0002] The power manager is used in programmable switch modules within a control system to control the power supply and triggering of peripheral devices such as lights, electric screens, electric curtains, and set-top boxes. By connecting to the central control system and receiving control codes, it performs timed, delayed, and sequenced switching of the power supplies to connected peripheral devices, thus managing and protecting these devices.

[0003] Currently, power managers are typically installed in control cabinets. For example, an IoT power manager disclosed in patent CN217720273U features a locking plate parallel to the back panel inside the housing. This locking plate is used to install the circuit breaker mechanism and the neutral and ground wire racks, while also enhancing the structural strength of the housing. In this structure, auxiliary inlets and outlets are provided at corresponding positions on the locking plate for wiring. During wiring, many component lines need to pass through these auxiliary inlets or outlets. Due to the large number of lines inside the housing, operators need to bend and adjust the lines at different locations to ensure they can pass through the corresponding auxiliary inlets or outlets. This process is not only time-consuming and labor-intensive, but also carries the risk of circuit breakage due to excessive bending. Furthermore, while this single-plate locking structure provides relatively stable structural strength, it also increases the weight of the device.

[0004] On the other hand, when the above-mentioned patented structure is applied to a server rack, the height of the rack makes it inconvenient to connect the power manager. It requires people to enter the rack to perform wiring and other work. Considering the limited space in the rack and the difficulty of wiring operations, especially when there are other devices below the power manager, the wiring difficulty is even greater, resulting in low wiring efficiency. Summary of the Invention

[0005] To overcome at least one of the defects in the prior art, this utility model provides a power manager that optimizes the locking plate structure, ensuring structural strength while facilitating wire passage and improving wiring efficiency; in addition, it can reduce the overall weight, making the entire device more portable.

[0006] This utility model provides a power manager comprising a housing consisting of a base plate, a top plate, a left side plate, a back plate, and a front cover. A circuit breaker mechanism is provided at one end of the housing near the front cover, and a through hole is provided on the front cover for the switch lever portion of the circuit breaker mechanism to pass through. An input interface and an output interface are provided on the back plate, and the circuit breaker mechanism is electrically connected to the input interface and the output interface, respectively. A reinforcing locking plate is also connected within the housing between the circuit breaker mechanism and the back plate. The reinforcing locking plate includes a rectangular outer frame connected to the inner peripheral wall of the housing, and several plates are connected between the two long sides of the rectangular outer frame to form multiple wire passageways between the rectangular outer frames.

[0007] Compared with the prior art, the power manager of this utility model has the following advantages:

[0008] In the power manager structure of this utility model, a short-circuit switch mechanism is installed inside the housing to control the safe switching of the circuit, ensuring the safety of the power supply line. Furthermore, a reinforced locking plate is also installed inside the housing to enhance structural strength. Compared to the traditional structure where a single metal plate serves as the locking plate, the reinforced locking plate in this utility model comprises a rectangular outer frame structure, supported and connected to the inner peripheral wall of the housing on all four sides. Several plates are connected between its two long sides, further enhancing the strength of the locking plate structure while creating multiple wire passageways between the rectangular outer frames. In practical applications, wires at various locations can easily pass through the wire passageways on the locking plate without requiring forceful bending or deformation, simplifying the wiring process and improving the operational efficiency of wiring personnel. Additionally, this reinforced locking plate structure is lighter, making the entire device more portable.

[0009] As an improvement, at least one of the strips has a support column connected to its rear end in the middle, and the end of the support column away from the strip is connected to the back plate. In the above improved structure, the addition of support columns provides front-to-back support and fixation for the locking plate structure, improving the structural strength after numerous components are installed inside the housing.

[0010] In a further improvement, the power output interface includes multiple power sockets of different specifications. In this improved structure, power sockets of different specifications and standards are directly embedded in the back panel to meet the power needs of different applications and expand the range of applications.

[0011] Furthermore, the back panel is also provided with a spare wiring hole, and a power supply connector is reserved inside the housing near the spare wiring hole; a cover plate for sealing the spare wiring hole is detachably connected to the outer wall of the back panel. In the above improved structure, after the spare wiring hole is set, if the user finds that the conventional national standard plug cannot meet the actual use needs during the use of the equipment, a wire can be directly connected to the circuit breaker of the equipment through the spare wiring hole, so that the output end can output the maximum current to meet the user's non-standard needs.

[0012] Furthermore, the back panel is provided with multiple cable tie holes for cable ties to pass through, enabling the binding and positioning of the wiring inside the back panel. This improved structure uses cable ties to organize the wiring, resulting in a simpler structure compared to traditional cable trays, and contributing to the weight reduction of the equipment from another perspective.

[0013] Furthermore, the circuit breaker mechanism includes a fixed cable tray, on which a switch module, a neutral wire busbar, and a ground wire busbar are connected. The fixed cable tray can move in the front-back direction within the housing to switch between the working position and the wiring position. When the fixed cable tray is in the wiring position, the wiring holes of the switch module, the neutral wire busbar, and the ground wire busbar extend beyond the front end face of the bottom plate of the housing.

[0014] Preferably, each of the left and right side plates is provided with a guide groove extending in the front-to-back direction, and each guide groove is provided with a connecting bolt extending from the outside to the inside and connecting to both ends of the fixed cable tray. In the above improved structure, the fixed cable tray and the housing are connected in an adjustable front-to-back position through the cooperation of the groove and the connecting bolt, which is simple in structure and easy to adjust.

[0015] Furthermore, the fixed cable tray includes a guide rail fixing frame horizontally arranged along the left-right direction of the housing. Both ends of the guide rail fixing frame are connected to support plates parallel to the two side plates of the housing. Each support plate has a threaded through hole for connecting bolts. A guide rail for mounting the switch module is connected to the front side wall of the guide rail fixing frame. The neutral wire busbar and ground wire busbar are respectively connected below both ends of the fixed cable tray. In the above structure, support plates are provided at both ends of the guide rail fixing frame for connecting bolts, resulting in a simple structure and convenient installation.

[0016] In a further improvement, the lower ends of both support plates are connected to fixed plates, the middle of the guide rail fixing frame is connected to a downwardly extending central support plate, and the neutral wire rack and the ground wire rack are horizontally connected between the central support plate and the two fixed plates, respectively.

[0017] In a further improvement, a horizontal positioning plate is connected to the lower end of the central support plate, and a positioning bolt is installed on the bottom plate of the housing. When the fixed cable tray moves outward to the wiring position, the lower end of the horizontal positioning plate abuts against the end of the positioning bolt. In the above improved structure, the horizontal positioning plate and the corresponding positioning bolt create a support point at the lower end of the guide rail fixing frame when the fixed cable tray is pulled outward to the wiring position. This improves the overall structural stability when the fixed cable tray moves outward to the wiring position and avoids structural bending deformation caused by the downward pressure on the guide rail fixing frame structure after connecting the zero-ground pressure line.

[0018] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0030] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] In the embodiments of this application, unless otherwise expressly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be in direct contact with the first feature, or indirect contact between the first and second features through an intermediate medium.

[0033] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1-9 As shown in the figure, this application discloses a foldable portable power manager, including a housing 1. The housing 1 is a rectangular structure composed of a bottom plate 2, a top plate, left and right side plates, a back plate 3, and a front cover 4. A circuit breaker mechanism is provided at one end of the housing 1 near the front cover 4, and a connecting hole 5 is provided on the front cover 4 for the switch block of the circuit breaker mechanism to pass through, ensuring the aesthetic appearance of the device. In addition, an inlet interface and an outlet interface are provided on the back plate 3 of the housing 1, and the circuit breaker mechanism is electrically connected to the inlet interface and the outlet interface respectively. This structure makes the outlet end more safe. Once the connected electrical appliance is short-circuited or other dangerous, the circuit breaker mechanism will automatically disconnect.

[0035] In the above structure, see Appendix Figure 2The top plate and the left and right side plates are an integral structure, that is, the left and right side plates are formed completely from both ends of the top plate downwards, eliminating the need for the connection between the top plate and the side plates, which makes processing convenient.

[0036] In one respect, in the above structure, see Appendix Figure 2 , 3 A reinforcing locking plate is also connected between the circuit breaker mechanism and the back plate 3 inside the housing 1 to enhance the structural strength between the side walls of the housing 1. In this embodiment, preferably, the reinforcing locking plate includes a rectangular outer frame 6 connected to the inner peripheral wall of the housing 1. Several plates 7 are connected between the two long sides of the rectangular outer frame 6 so that multiple wire passage channels 8 are formed between the rectangular outer frames 6. In practical applications, the wires at each position can easily pass through the wire passage channels 8 on the locking plate without having to bend or deform them, which simplifies the wiring process and improves the operating efficiency of the wiring personnel.

[0037] On the other hand, at least one of the strip plates 7 has a horizontal support column 9 connected to its rear end. The end of the support column 9 away from the strip plate 7 is connected to the back plate 3. Specifically, both ends of the support column 9 are connected to the strip plate 7 and the back plate 3 by screws. The addition of the support column 9 provides front-to-back support and fixation for the locking plate structure, improving the structural strength of the housing 1 after installing numerous components.

[0038] In this structure, please continue to refer to the appendix. Figure 3 Preferably, three strips 7 are provided between the two long sides of the rectangular outer frame 6, and support columns 9 are provided between the two strips 7 on both sides and the back plate 3. Of course, in other embodiments, support columns 9 may be provided only between the middle strip 7 and the back plate 3, or support columns 9 may be provided between all three strips 7 and the back plate 3.

[0039] Additionally, in this embodiment, see Appendix Figure 4 The power output interface includes multiple power sockets 10 of different specifications. That is, multiple mounting through holes are provided on the back plate 3, and power sockets 10 of different specifications, models and standards are respectively installed in each mounting through hole to meet the power needs of different applications.

[0040] In the above structure, the various power sockets 10 provided in the standard configuration can meet almost all the customer's regular connection needs. To avoid unexpected special wiring requirements, the equipment structure has been further optimized in this embodiment. Specifically, please refer to the appendix. Figure 4A new elongated spare wiring hole 11 has been added to the back plate 3. A power supply connector is reserved inside the housing 1 near the spare wiring hole 11. A cover plate 12 for sealing the spare wiring hole 11 is detachably connected to the outer wall of the back plate 3. When users find that the conventional national standard plug cannot meet their actual needs during use, they can directly connect the circuit breaker of the equipment through the spare wiring hole 11, so that the output end can output the maximum current to meet the user's needs. This not only controls the standard but also gives us a differentiated advantage compared to similar products. Under normal circumstances, this rectangular through hole can be sealed by the cover plate 12, ensuring the safety of the equipment and expanding the application range of the equipment itself.

[0041] In this embodiment, to simplify the user's wiring process, an inlet wiring hole is provided on the back plate 3, and a row of terminal blocks 30 are set at the corresponding positions, providing users with a convenient and quick wiring channel. Furthermore, after all lines are connected, to make the equipment wiring more organized, numerous cable tie holes 13 are provided on the back plate 3 of the housing 1 and on the outer cover of the terminal blocks 30. Compared to traditional cable trays, the cable tie holes 13 simplify the equipment structure while retaining the need for neat equipment wiring. The cable tie binding method is also more stable and reliable, avoiding possible wire detachment during internal pulling and interference between wires and components, and is also lighter than cable trays.

[0042] In this embodiment, the circuit breaker mechanism includes a fixed cable tray, on which a switch module 14, a neutral wire busbar 15, and a ground wire busbar 16 are connected. The fixed cable tray can move back and forth within the housing 1 to switch between a working position and a wiring position. When the fixed cable tray is in the wiring position, the wiring holes of the switch module 14, the neutral wire busbar 15, and the ground wire busbar 16 extend beyond the front end face of the bottom plate 2 of the housing 1. This allows for more operating space below the housing 1 when wiring, after removing the front cover 4, without changing the volume of the housing 1, thus facilitating wiring.

[0043] In this embodiment, preferably, guide grooves 17 extending in the front-to-back direction are provided on both side plates of the housing 1. These guide grooves 17 penetrate the side plates of the housing 1, and connecting bolts 18 extending from the outside to the inside and connecting to both ends of the fixed cable tray are inserted in each guide groove 17. In this structure, in the working position, the fixed cable tray is fixed to the housing 1 by tightening the connecting bolts 18. Similarly, in the wiring position, the connecting bolts 18 are also tightened to ensure the stability of the fixed cable tray. This better ensures that the switch module 14, neutral wire bracket 15, and ground wire bracket 16 will not change position during wiring, thus ensuring the accuracy of the wiring position. Of course, when it is necessary to move the fixed cable tray, the connecting bolts 18 need to be loosened. The fixed cable tray is slidably supported on the side plates of the housing 11 by the connecting bolts 18 at both ends.

[0044] In other embodiments, sliding rails extending forward and backward can be provided on the inner walls of the left and right side plates of the housing 1. The two ends of the fixed cable tray are slidably engaged on the sliding rails by sliders. In addition, corresponding connection holes are provided on the left and right side plates at positions corresponding to the working position and the wiring position. These holes are used to insert positioning pins during connection. That is, when the fixed cable tray slides inward to the working position, the positioning pin is inserted into the connection hole at the rear end of the side plate, and its inner end is also inserted into and limited by the fixed cable tray. Similarly, when the fixed cable tray moves outward to the wiring position, the positioning pin is inserted into the connection hole at the front end of the side plate, and its inner end is inserted into and limited by the fixed cable tray, ensuring the stability of the fixed cable tray during wiring.

[0045] In addition, to further improve the positional stability of the fixed cable tray in its working and wiring positions, this implementation refers to the appendix. Figure 5 and 6 Each guide slide 17 has a recessed positioning groove 19 at both its front and rear ends. When the fixed cable tray is in the working position, the connecting bolt 18 is locked and limited in the positioning groove 19 at the rear end of the guide slide 17. When the fixed cable tray moves to the wiring position, the connecting bolt 18 is locked and limited in the positioning groove 19 at the front end of the guide slide 17. The guide grooves prevent the connecting bolt 18 from sliding back and forth in the guide slide 17, thus limiting its position.

[0046] More specifically, the fixed bridge in the above structure includes a guide rail fixing frame 20 arranged horizontally along the left and right direction of the housing 1. Both ends of the guide rail fixing frame 20 are connected to support plates 21 that are parallel to the two side plates of the housing 1. Each support plate 21 is provided with threaded through holes for connecting bolts 18. The guide rail fixing frame 20 here is a long strip-shaped fixing plate 23 structure, with a guide rail 22 connected to its front side wall. The guide rail 22 is provided with multiple waist-shaped holes extending along its length for installing switch modules 14.

[0047] Additionally, the neutral wire rack 15 and the ground wire rack 16 are respectively connected to the lower ends of the fixed cable tray. Specifically, a fixed plate 23 is connected to the lower end of each of the two support plates 21, and a downward-extending central support plate 24 is connected to the middle of the guide rail fixing frame 20. The neutral wire rack 15 and the ground wire rack 16 are horizontally connected between the central support plate 24 and the two fixed plates 23.

[0048] In this embodiment, see Appendix Figure 7 , 8 The lower ends of the central support plates 24 are all connected to horizontal positioning plates 26, and positioning bolts 25 are installed on the bottom plate 2 of the housing 1. When the fixed cable tray moves outward to the wiring position, the lower ends of the horizontal positioning plates 26 abut against the ends of the positioning bolts 25 respectively; forming a support point at the lower end of the guide rail fixing frame 20, improving the overall structural stability when the fixed cable tray moves outward to the wiring position, and avoiding structural bending deformation caused by the downward pressure on the guide rail fixing frame 20 structure after connecting the zero ground pressure line. In this structure, the horizontal positioning plates 26 are formed by bending the lower ends of the central support plates 24, which facilitates processing and reduces costs.

[0049] In some other embodiments, the lower ends of the two fixing plates 23 can also be bent into horizontal positioning plates 26, and correspondingly, protruding positioning posts are set at corresponding positions on the bottom plate 2 of the housing 1. When the fixed cable tray moves outward to the wiring position, the lower ends of the horizontal positioning plates 26 at the lower ends of the two fixing plates 23 abut against the ends of the two positioning posts respectively, further improving the stability of the fixed cable tray structure.

[0050] The support plate 21 and the middle support plate 24 in the above structure play a supporting role in the overall structure, which can make the pressure borne by the guide rail fixing frame 20 more even and avoid the collapse and deformation that may occur when installing the circuit breaker and the neutral and ground wires later. The fixing plate 23 on the support plate 21 serves as a supporting component of the mechanism to improve the stability of the structure, and also serves as a mounting frame for the neutral wire frame 15 and the ground wire frame 16.

[0051] In addition, multiple limiting brackets 29 are connected to the fixed cable tray. When the fixed cable tray is in the working position, each limiting bracket 29 is abutted against and limited by the rectangular outer frame 6. Specifically, in this embodiment, vertically extending limiting brackets 29 are connected to the rear sides of both ends of the guide rail fixing frame 20, and the upper ends of the limiting brackets 29 are bent into horizontal abutment plates that abut against the two short sides of the rectangular outer frame 6.

[0052] Furthermore, in the above structure, see Appendix Figure 5 and 7Each of the two support plates 21 has a handle plate 27 connected to its front end, and both handle plates 27 have clearance holes 28 at their front ends. When the cable tray needs to be moved, grasping the clearance holes 28 with both hands ensures that the cable tray can move horizontally, preventing jamming and thus saving effort. In this embodiment, the front cover 4 also has two clearance channels for the front ends of the handle plates 27 to pass through.

[0053] In the above structure, preferably, vertical connecting plates are integrally bent at both ends of the guide rail fixing frame 20, and vertical stiffeners are connected between the two vertical connecting plates at each end. The upper and lower ends of the vertical stiffeners are bent into L-shaped supports that abut against the locking plate. In addition, the two ends of the fixing bridge are bent backward to form horizontal connecting plates. Two support plates 21 are respectively connected to the two horizontal connecting plates, and two threaded holes are provided at the upper and lower ends of each support plate 21, that is, four threaded holes are provided on each support plate 21. Correspondingly, four guide grooves 17 are provided on the left and right side plates of the housing 1, and four connecting bolts 18 are connected to each side of the housing 1 to ensure the stability of the connection structure between the fixing bridge and the side plates of the housing 1.

[0054] In this structure, a support base plate is also bent and installed in the middle of the support plate 21. When in the working position, the support base plate also abuts against the locking plate, which further enhances the structural strength of the fixed cable tray and improves its load-bearing capacity.
