Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply device technology, and in particular to a control frame. Background Technology
[0002] With the continuous development of power systems, high-voltage direct current (HVDC) transmission technology has been widely applied in places such as AI data centers. HVDC electrical systems provide power assurance for data center cabinets, and their safe and stable operation is crucial. In the event of a power outage or power failure in the HVDC electrical system, BBU (Battery Backup Unit) modules are typically used to provide stable power to critical equipment (such as switches, routers, and servers) to ensure continuous equipment operation and prevent data loss and system crashes. The BBU module in the system is generally inserted into a frame, and mechanical limits are used to lock the BBU module to the outer frame. After mechanical unlocking, the BBU module can be pulled out for disassembly and maintenance. After the BBU module is installed in the frame, the connector at the rear of the BBU module is electrically connected to the PCB board inside the frame. In actual operation, if the operator pulls out the BBU module while it is energized (with the connector electrically connected to the PCB board), arcing may occur, affecting the safety of the operation and shortening the electrical life of the system connection points. Utility Model Content
[0003] Therefore, it is necessary to provide a control block that can improve operational safety and extend the electrical life of system connection points to address the above-mentioned shortcomings.
[0004] A control box, comprising: The insert frame has a receiving space inside, the front side of the insert frame has an insertion interface communicating with the receiving space, and the inner side of the insert frame has a first limiting structure near the insertion interface, and the rear side of the insert frame has a PCB board located in the receiving space. A BBU module, which is retractably inserted into the receiving space via the connector, has a pressable locking handle on its front side. The locking handle has a second limiting structure that engages with the first limiting structure when the locking handle rebounds. The rear side of the BBU module has a connector electrically connected to the PCB board, and the BBU module contains a contactor for controlling the on / off state of its main circuit. A switch module is provided, which cooperates with the locking handle and is electrically connected to the contactor; the switch module is turned on when the locking handle is engaged with the first limiting structure, and turned off when the locking handle is removed from the first limiting structure.
[0005] In one embodiment, the first limiting structure is a limiting groove formed on the inner side of the insert frame, and the upper surface of the middle part of the locking handle is provided with at least one hook forming the second limiting structure, and the hook engages with the limiting groove.
[0006] In one embodiment, the distance from the rear side of the slot opening of the limiting groove to the insertion interface is greater than or equal to the length of the electrical connection between the connector and the PCB board in the BBU module pull-out direction.
[0007] In one embodiment, the hook is a plate-like structure arranged in a vertical direction, the upper surface of the hook is a plane, the front side of the hook is a vertical surface, the rear side of the hook is provided with an inclined surface, and the height of the inclined surface gradually increases from the rear side to the front side of the hook.
[0008] In one embodiment, the front side of the BBU module is provided with a status indicator light that is electrically connected to the main circuit of the BBU module.
[0009] In one embodiment, one end of the locking handle is fixedly connected to the top cover of the BBU module, and the other end of the locking handle extends from the front side of the BBU module to form a pressing part. The top cover of the BBU module has a pressing relief groove corresponding to the locking handle and penetrating the front side of the BBU module.
[0010] In one embodiment, a protective rubber sleeve is fixed to the pressing part, and the upper surface of the protective rubber sleeve is provided with anti-slip texture.
[0011] In one embodiment, the locking handle is connected to the top cover screw of the BBU module, and the top cover of the BBU module is recessed to form the U-shaped pressing relief groove.
[0012] In one embodiment, the switch module is a micro switch fixed to the inner side of the top plate of the insert frame and adjacent to the insert interface. The middle part of the locking handle is bent to form a groove corresponding to the micro switch. When the locking handle is pressed down, the micro switch separates from the bottom surface of the groove and disconnects. When the locking handle returns to its original position and engages with the first limiting structure, the micro switch abuts against the bottom surface of the groove and becomes conductive.
[0013] In one embodiment, the switch module includes a first proximity sensor fixed to the top cover of the BBU module and a second proximity sensor fixed to the locking handle. The first proximity sensor and the second proximity sensor cooperate to form a sensing circuit. When the locking handle is pressed down, the second proximity sensor moves away from the first proximity sensor, and the sensing circuit is disconnected. When the locking handle returns to its original position and engages with the first limiting structure, the second proximity sensor approaches the first proximity sensor, and the sensing circuit is closed.
[0014] The control frame implementing this utility model, through the cooperation of the locking handle and the first limit structure, can realize the mechanical locking and unlocking of the BBU module and the insertion frame. By setting a switch module electrically connected to the contactor and cooperating with the locking handle, the switch module is synchronously turned on or off during the locking and unlocking process of the locking handle and the insertion frame. The mechanical locking of the BBU module and the linkage of the switch module realize the main circuit opening and closing control of the BBU module pulling process. During the BBU module pulling process, when the locking handle is pressed to mechanically unlock the BBU module, the BBU module is immediately de-energized. There is no need to specifically de-energize the BBU module in advance, which can avoid the arcing phenomenon caused by live operation, realize arc-free disconnection, improve the safety of operation, and extend the electrical life of the system connection points.

Detailed Implementation
[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0017] Please see Figure 1This utility model discloses a control frame that can improve operational safety and extend the electrical life of system connection points. The control frame includes a plug frame 100, a BBU module 200, and a switch module 300. The plug frame 100, also known as a BBU plug frame, is a standardized chassis or rack unit that provides centralized installation, power supply, management, and communication for multiple BBU modules 200. The insertion frame 100 has a receiving space 110. A insertion interface 120 communicating with the receiving space 110 is provided on the front side of the insertion frame 100, serving as a channel for the BBU module 200 to enter the receiving space 110. A first limiting structure 130 is provided on the inner side of the insertion frame 100 near the insertion interface 120, providing a mechanical locking point for the BBU module 200. A PCB board 140 is located on the rear side of the insertion frame 100 within the receiving space 110. The PCB board 140 is electrically connected to the BBU module 200 inserted into the receiving space 110, providing high-voltage DC power input and output to the BBU module 200. The BBU module 200 can be pulled into the receiving space 110 via the insertion interface 120; that is, the BBU module 200 can be inserted into the receiving space 110 to provide power during use, and can also be removed from the receiving space 110 for maintenance and replacement as needed. The front side of the BBU module 200 is provided with a pressable and spring-back locking handle 210. That is to say, the locking handle 210 has a certain elasticity, which allows the locking handle 210 to deform when pressed and to return to its original position after the pressure is released, thereby changing the positional relationship between the locking handle 210 and other structural components. The locking handle 210 is provided with a second limiting structure 220 that engages with the first limiting structure 130 when the locking handle 210 rebounds. In this way, after the locking handle 210 resets and rebounds, the second limiting structure 220 engages with the first limiting structure 130, which can achieve mechanical locking between the BBU module 200 and the insert frame 100, so as to prevent the BBU module 200 from sliding out of the insert frame 100 under external impact, and at the same time prevent personnel from accidentally pulling out the BBU module 200. When it is necessary to pull out the BBU module 200, the operator must first press down the locking handle 210 to release the constraint between the second limiting structure 220 and the first limiting structure 130 on the locking handle 210, so as to unlock the physical connection between the BBU module 200 and the insert frame 100. The rear side of the BBU module 200 is provided with a connector 230 that is electrically connected to the PCB board 140. This connector 230 serves as the electrical connection point between the BBU module 200 and the insertion frame 100, allowing the BBU module 200 to input or output corresponding electrical signals. The mating arrangement of the connector 230 and the PCB board 140 is as follows: Figure 2As shown, during the insertion of the BBU module 200 into the insert frame 100, the lower surface of the connector 230 is attached to the upper surface of the PCB board 140 and electrically connected. The contact section between the lower surface of the connector 230 and the upper surface of the PCB board 140 is the connection section between the two, allowing for a large contact area to ensure a stable connection between the connector 230 and the PCB board 140 after the BBU module 200 is inserted. The BBU module 200 includes a contactor 240 for controlling the on / off state of the main circuit of the BBU module 200. The switch module 300 cooperates with the locking handle 210 and is electrically connected to the contactor 240. The switch module 300 is turned on when the locking handle 210 engages with the first limiting structure 130 and is turned off when the locking handle 210 leaves the first limiting structure 130, thus enabling the switch module 300 and the locking handle 210 to work together.
[0018] When the locking handle 210 is pressed down and the second limiting structure 220 separates from the first limiting structure 130, the BBU module 200 is mechanically unlocked from the insertion frame 100. At the same time, the switch module 300 is disconnected, and correspondingly, the contactor 240 is also disconnected, thereby de-energizing the main circuit of the BBU module 200. This ensures that the BBU module 200 is de-energized while the locking handle 210 is pressed down, avoiding arcing caused by live operation during the pulling out of the BBU module 200. Similarly, when the BBU module 200 is inserted into the insert frame 100, the second limiting structure 220 is squeezed by the inner side of the insert frame 100, causing the locking handle 210 to be pressed. During this process, the switch module 300 remains in the off state until the BBU module 200 moves into the insert frame 100 until the second limiting structure 220 and the first limiting structure 130 are engaged and the connector 230 is connected to the PCB board 140. Under these conditions, the locking handle 210 is reset, and the switch module 300 is turned on. Since the connector 230 is connected to the PCB board 140, the BBU module 200 is powered on.
[0019] Please see Figure 3The receiving space has multiple mounting positions formed horizontally, and each mounting position can accommodate one BBU module 200. Thus, multiple BBU modules 200 can be installed in the insertion frame 100 at once to meet the system's power requirements. One of the first limiting structure 130 and the second limiting structure 220 can be a slot and the other a buckle, or both the first limiting structure 130 and the second limiting structure 220 can be protruding structures, staggered and engaging when they approach each other to restrict the position of the BBU module 200 along the length of the insertion frame 100. Of course, other engaging structures or other mechanical limiting structures can also be used between the locking handle 210 and the insertion frame 100. For example, the first limiting structure 130 and the second limiting structure 220 can be magnets, using magnetic attraction to limit the movement of the BBU module 200 between them and the insertion frame 100. The BBU module 200 contains not only the main circuit and contactors, but also relays and other control devices. The specific types of other devices in the BBU module 200 are not covered by this solution.
[0020] Please combine Figure 3 and Figure 4In this embodiment, the first limiting structure 130 is a limiting groove formed on the inner side of the insert frame 100, and the second limiting structure 220 is a latching part protruding on the locking handle 210 and embedded in the limiting groove. The upper surface of the middle part of the locking handle 210 is provided with at least one hook forming the second limiting structure 220. The hook engages with the limiting groove to achieve mechanical limiting between the locking handle 210 and the insert frame 100. The limiting groove can be formed on the top plate of the insert frame 100, or on the side plate or bottom plate of the insert frame 100. Correspondingly, the position of the locking handle 210 on the BBU module 200 corresponds to the position of the limiting groove on the insert frame 100, so that the locking handle 210 matches the corresponding limiting groove. For ease of description, in each embodiment of this solution, the limiting groove is formed on the top plate of the insert frame and the locking handle 210 is set on the top cover of the BBU module 200. Other openings of the limiting groove on the insert frame 100 and other setting positions of the locking handle 210 on the BBU module 200 are still within the protection scope of this solution. The depth of the limiting groove can be less than the thickness of the top plate of the insert frame 100 or equal to the thickness of the top plate of the insert frame 100. In this embodiment, the depth of the limiting groove is equal to the thickness of the top plate of the insert frame 100. That is, the limiting groove penetrates the outer surface of the top plate of the insert frame 100. In this way, by increasing the height of the snap-fit part, the snap-fit part can be made to protrude from the top plate of the insert frame 100 after being inserted into the limiting groove, thereby increasing the mating area between the snap-fit part and the limiting groove and improving the structural stability of the BBU module 200 when locked with the insert frame 100. In addition, in this embodiment, the limiting groove can extend either along the width direction of the insert frame 100 (i.e., the arrangement direction of the multiple BBU modules 200 within the insert frame 100) or along the length direction of the insert frame 100 (i.e., the pulling direction of the BBU module 200 within the insert frame 100). The portion of the insert frame 100 used for mechanically locking the same BBU module 200 can have only one limiting groove, or multiple limiting grooves can be arranged side-by-side. Correspondingly, the number of engaging parts on the locking handle 210 is adapted to the number of limiting grooves, thereby increasing the number of mating points between the locking handle 210 and the insert frame 100 during mechanical locking and improving the connection strength between the locking handle 210 and the insert frame 100 during mechanical locking. Preferably, in this embodiment, the limiting groove extends along the length direction of the insert frame 100, and two limiting grooves are arranged side-by-side along the width direction at the portion corresponding to the same locking handle 210. Two engaging parts corresponding to the two limiting grooves are arranged side-by-side on the locking handle 210.
[0021] Furthermore, the PCB board 140 is fixed to the rear side of the base plate of the insertion frame 100. After the BBU module 200 is fully inserted into the insertion frame 100, the rear side of the BBU module 200 abuts against the edge of the PCB board 140, and the connector 230 on the BBU module 200 is connected to the upper surface of the PCB board 140. In this embodiment, when the first limiting structure is a limiting groove and the second limiting structure is a snap-fit part embedded in the limiting groove, the distance from the rear side of the limiting groove opening to the insertion interface is greater than or equal to the length of the electrical connection part between the connector 230 and the PCB board 140 in the pulling direction of the BBU module 200. That is, during the process of the BBU module 200 being pulled out of the insertion frame 100, before the snap-fit part on the locking handle is completely disengaged from the restriction of the inner side of the insertion frame 100, the connector 230 of the BBU module 200 is connected to the upper surface of the PCB board 140. 40 Disconnection, that is, before the connector 230 on the rear side of the BBU module 200 is disconnected from the PCB board 140, during the pulling out of the BBU module 200, the locking part on the locking handle is restricted by the top plate of the insertion frame 100 and will not spring back. The travel of the locking part under the top plate of the insertion frame is greater than the travel of the connector 230 at the tail of the BBU module 200 disengaging from the PCB board 140. Therefore, during the entire pulling out process, the switch module will not close before the connector 230 is completely disconnected, so as to ensure the safety of operation.
[0022] In this embodiment, when the second limiting structure 220 is a hook, the hook is a plate-shaped structure arranged in the vertical direction. The upper surface of the hook is a plane, the front side of the hook is a vertical surface, and the rear side of the hook is provided with an inclined surface. The height of the inclined surface gradually increases from the rear side to the front side of the hook. The rear side of the hook refers to the side of the hook adjacent to the rear side of the BBU module, and the front side of the hook refers to the side of the hook adjacent to the front side of the BBU module. In this embodiment, by setting the upper surface of the hook as a plane, the upper surface of the hook can fit against the lower surface of the top plate of the insertion frame 100 during the pulling out process of the BBU module 200, increasing the contact area between the hook and the top plate of the insertion frame, thereby reducing the wear of the hook on the top plate of the insertion frame. The vertical surface on the front side of the hook allows the inner side of the limiting groove to fit against the front side of the hook after the hook is embedded in the limiting groove, thereby increasing the contact area between the two and improving the reliability of the limiting groove in limiting the hook. By setting an inclined surface on the rear side of the hook, during the insertion of the BBU module 200 into the insertion frame 100, on the one hand, the impact of the hook on the edge of the insertion interface can be reduced, and on the other hand, through the sliding cooperation between the inclined surface and the edge of the insertion interface, while facilitating the movement of the hook into the insertion frame 100, the locking handle 210 is pressed down and deformed by the pressing of the hook by the top plate of the insertion frame, thereby reducing the difficulty of inserting the BBU module 200 into the insertion frame 100.
[0023] Please refer to the following: Figure 3The front side of the BBU module 200 is equipped with a status indicator light 250 that is electrically connected to the main circuit of the BBU module 200. The status indicator light 250 is used to light up when the main circuit of the BBU module 200 is powered on and to turn off when the main circuit of the BBU module 200 is powered off. This allows the operator to judge the power supply status of the BBU module 200 by observing the brightness of the status indicator light 250. In this way, even if the switch module fails, the operator can still judge the power supply status of the BBU module 200 by observing the status indicator light 250, so as to avoid operating the BBU module 200 while it is powered on and improve the safety of the operation.
[0024] Please see Figure 5 The locking handle 210 has a strip-shaped structure and is made of elastic material to ensure that it can deform when pressed at the end. One end of the locking handle 210 is fixedly connected to the top cover of the BBU module 200, and the other end of the locking handle 210 extends from the front side of the BBU module 200 to form a pressing part. The top cover of the BBU module 200 has a pressing relief groove 260 corresponding to the locking handle 210 and penetrating the front side of the BBU module 200. Furthermore, a protective rubber sleeve 211 is fixed at the pressing part, and the upper surface of the protective rubber sleeve 211 has anti-slip texture 212. In this way, on the one hand, the end of the locking handle 210 is protected and prevented from scratching external objects or personnel; on the other hand, it helps to improve the feel of the operator when operating the pressing part and prevents slippage. In addition, the locking handle 210 is connected to the top cover of the BBU module 200 by screws. The top cover of the BBU module 200 is recessed to form a U-shaped pressing relief groove 260 to ensure that the locking handle 210 can be pressed down smoothly, so that the locking handle 210 has sufficient deformable space.
[0025] In this solution, the switch module 300 includes two forms depending on the circuit response method. The specific structure of the switch module 300 and the operation process of the control box are illustrated below with specific examples.
[0026] Please see Figure 5In one embodiment, the switch module 300 is a microswitch fixed to the inner side of the top plate of the insert frame 100 and adjacent to the insert interface. The middle part of the locking handle 210 is bent to form a groove 213 corresponding to the microswitch. When the locking handle 210 is pressed down, the microswitch separates from the bottom surface of the groove 213 and disconnects. When the locking handle 210 returns to its original position and engages with the first limiting structure 130, the microswitch abuts against the bottom surface of the groove 213 and conducts electricity. In this embodiment, the control circuits of the microswitch and the contactor are electrically connected. The opening and closing of the microswitch controls the opening and closing of the contactor. The contactor is electrically connected to the main circuit of the BBU module 200. Thus, when the contactor is disconnected, the main circuit is simultaneously disconnected, thereby de-energizing the BBU module 200. The opening and closing status of the main circuit is indicated by a status indicator light. When the BBU module 200 is inserted into the insert frame 100 and installed in place, the connector on the rear side of the BBU module 200 is electrically connected to the PCB board. At this time, the hook on the locking handle 210 springs back into the limit groove, and the micro switch is pressed down. The state of the micro switch is as follows: Figure 6 As shown, at this time, the contactor associated with the micro switch is connected, the BBU module 200 is powered on, and the status indicator light illuminates.
[0027] Please combine Figure 7-8 When the BBU module 200 needs to be pulled out, press the end of the locking handle 210. The hook on the locking handle 210 disengages from the limit slot, and the micro switch is released. The state of the micro switch is as follows: Figure 9 As shown, at this time, the contactor associated with the micro switch is disconnected, causing the BBU module 200 to lose power, and the status indicator light goes out.
[0028] Please see Figure 10In another embodiment, the switch module 300 includes a first proximity sensor 310 fixed on the top cover of the BBU module 200 and a second proximity sensor 320 fixed on the locking handle 210. The first proximity sensor 310 and the second proximity sensor 320 cooperate to form a sensing circuit. When the locking handle 210 is pressed down, the second proximity sensor 320 moves away from the first proximity sensor 310, and the sensing circuit is disconnected. When the locking handle 210 returns to its original position and engages with the first limiting structure 130, the second proximity sensor 320 approaches the first proximity sensor 310, and the sensing circuit is closed. It should be noted that in this embodiment, when the first limiting structure 130 and the second limiting structure 220 are engaged, the first proximity sensor 310 and the second proximity sensor 320 are at the same horizontal height. At this time, the sensing circuit composed of the first proximity sensor 310 and the second proximity sensor 320 outputs a connection signal. When the first proximity sensor 310 and the second proximity sensor 320 are not at the same horizontal height, the sensing circuit outputs a disconnection signal. The sensing circuit is connected to the control circuit of the contactor. The opening and closing of the contactor is controlled by the connection and disconnection of the sensing circuit. The contactor is connected to the main circuit of the BBU module 200. When the controller is disconnected, the main circuit is disconnected. The opening and closing status of the main circuit is displayed by a status indicator light. The first proximity sensor 310 and the second proximity sensor 320 can be one of the following: inductive proximity sensor, capacitive proximity sensor, photoelectric proximity sensor, and magnetic induction proximity sensor.
[0029] Once the BBU module 200 is inserted into the insert frame 100 and installed in place, the connector on the rear side of the BBU module 200 is electrically connected to the PCB board. At this time, the hook on the locking handle 210 springs back into the limiting groove, the first proximity sensor 310 and the second proximity sensor 320 approach each other and output a connection signal, connecting the associated contactor, and the BBU module 200 is powered on, illuminating the status indicator light. Please refer to [link / reference]. Figure 11 When the BBU module 200 needs to be pulled out, press the end of the locking handle 210. The hook on the locking handle 210 disengages from the limiting groove. At the same time, the second proximity sensor 320 moves away from the first proximity sensor 310. The sensing circuit outputs a disconnect signal, and the associated contactor disconnects, causing the BBU module 200 to lose power and the status indicator light to turn off.
[0030] The control frame implementing this utility model, through the cooperation of the locking handle 210 and the first limiting structure 130, can realize the mechanical locking and unlocking of the BBU module 200 and the insertion frame 100. By setting a switch module 300 electrically connected to the contactor 240 and cooperating with the locking handle 210, the switch module 300 is synchronously turned on or off during the locking and unlocking process of the locking handle 210 and the insertion frame 100. The mechanical locking of the BBU module 200 and the switch module 300 are linked to realize the main circuit opening and closing control of the BBU module 200 during the pulling process. During the pulling process of the BBU module 200, when the locking handle 210 is pressed to mechanically unlock the BBU module 200, the BBU module 200 is immediately de-energized. There is no need to specifically de-energize the BBU module 200 in advance, which can avoid the arcing phenomenon caused by live operation, realize arc-free disconnection, improve the safety of operation, and extend the electrical life of the system connection points.
[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
