Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a connection structure between the power supply box and the control box of a small black box for power control. Background Technology

[0002] In traditional brightness control products (such as the "small black box"), the controller is typically connected using screws. This installation method is not only cumbersome and inefficient, requiring additional tools such as screwdrivers, but it can also cause stripped screws, wear and tear on components, or even damage during repeated disassembly and assembly, affecting structural stability and lifespan. Furthermore, screw connections also make later maintenance and repair inconvenient, increasing labor and time costs. Therefore, this connection structure of existing controllers can no longer meet users' higher requirements for convenient installation and user experience. There is an urgent need for a solution with optimized structure, stable connection, and tool-free rapid assembly. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a connection structure between the power supply box and the control box of a power control black box.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power supply box and control box connection structure for a small black box for power control, including a power supply box for installing power and a control box; the power supply box is provided with a connector, and the control box is provided with a connector portion that mates with the connector; the connector portion includes a socket and a guide slope located on the socket inlet side; the connector includes a plug and a mating slope formed on the plug; the power supply box is connected to the control box in a top-to-bottom installation manner, and the plug is guided to slide into the socket until it reaches the locking position through the interaction of the mating slope and the guide slope.

[0005] As a preferred embodiment of this utility model, a guide plate is provided on the inlet side of the insertion hole, and the guide plate is provided with the guide slope; when the insertion block reaches the locking position, its mating slope and the guide slope fit together.

[0006] As a preferred embodiment of this utility model, the bottom of the guide plate is provided with a support platform; when the insert block reaches the locking position, the bottom of the insert block abuts against the support platform.

[0007] As a preferred embodiment of this utility model, the plug has a plate-like structure, and a receiving gap is formed between the plug and the outer wall of the power supply box for inserting the guide plate; the receiving gap has an opening on the side facing the guide plate, and the mating inclined surface is formed on the side of the plug away from the opening.

[0008] As a preferred embodiment of this utility model, the inner wall of the insertion hole is provided with a locking structure at the locking position, and the insertion block is provided with a corresponding structure that cooperates with the locking structure; the locking structure is a locking block or a locking groove, and the corresponding structure is a corresponding locking groove or a locking block.

[0009] As a preferred embodiment of this utility model, the upper part of the card block is provided with an inlet slope.

[0010] As a preferred embodiment of this utility model, the power supply box is provided with the plug-in component on both sides along its length direction; the control box is provided with the plug-in portion that cooperates with the plug-in component on both sides along its length direction.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: Through the interaction of the guide slope and the mating slope, precise guidance and rapid docking between the power supply box and the control box are achieved. The installation process requires no external tools; a simple plug-in action is all that's needed. This completely overcomes the cumbersome and inefficient nature of traditional screw fixing methods, significantly reducing installation time and labor costs. Specifically, the connection method where the plug slides into the socket and finally reaches the locking position, the interlocking action of the locking block and slot, the supporting surface's support, and the tight fit of the slopes form multiple limiting and stable support, ensuring the mechanical stability and electrical continuity of the connection under complex environments such as vibration, effectively avoiding connection failures caused by loose screws or stripped threads. This application eliminates the hassle of finding and using tools, simplifying the complex installation process into a one-step direct plug-in operation, fundamentally improving the user experience.

The connector portion includes a socket 3 and a guide slope 4 located at the entrance of the socket 3. The connector includes a plug 5 and a mating slope 6 formed on the plug 5. The power box is installed from top to bottom with the control box 2. The interaction between the mating slope 6 and the guide slope 4 guides the plug 5 to slide into the socket 3 until it reaches the locking position. In this embodiment, the small black box is a standard black cuboid, integrating the control module and the power supply unit. The size of the power control black box is usually within the range of (length ≤ 300mm, width ≤ 150mm, height ≤ 50mm), which is a compact design. The specific external dimensions of this application are 283.5mm (length) x 135mm (width) x 40mm (height). Within this range and compared with similar power control black boxes, it has a higher space utilization rate and is more compact.

[0017] Through the interaction of the guide ramp 4 and the mating ramp 6, precise guidance and rapid docking between the power supply box and the control box 2 are achieved. The installation process requires no external tools; a simple plug-in action is all that's needed. This completely overcomes the cumbersome and inefficient nature of traditional screw-fixing methods, significantly reducing installation time and labor costs. Specifically, the connection method of the plug 5 sliding into the socket 3 and finally reaching the locking position, the snap-fit ​​between the locking block 11 and the slot 12, the support of the support platform 8, and the tight fit of the ramps form multiple limits and stable support, ensuring the mechanical stability and electrical continuity of the connection under complex environments such as vibration, effectively avoiding connection failures caused by loose screws or stripped threads. This application eliminates the hassle of finding and using tools, simplifying the complex installation process into a one-step direct plug-in operation, fundamentally improving the user experience.

[0018] The improvement in this application lies in the innovative mechanical connection structure between the power supply box 1 and the control box 2, specifically involving the physical engagement method of the connectors and the plug-in parts, including achieving rapid guidance and locking through the interaction of the guide slope 4 and the mating slope 6. This solution primarily addresses the convenience and reliability of assembling the power module and control module housings. How the control module adjusts the display brightness, and how the power supply and control box 2 are electrically connected via cables or circuits, employs existing mature technologies and is not the focus of this application.

[0019] A guide plate 7 is provided on the inlet side of the socket 3, and a guide slope 4 is provided on the guide plate 7; when the plug 5 reaches the locking position, its mating slope 6 and the guide slope 4 are in contact with each other. A support platform 8 is provided at the bottom of the guide plate 7; when the plug 5 reaches the locking position, the bottom of the plug 5 abuts against the support platform 8.

[0020] The plug 5 has a plate-like structure, and a receiving gap 9 is formed between the plug 5 and the outer wall of the power box 1 for the guide plate 7 to be inserted; the receiving gap 9 has an opening 10 on the side facing the guide plate 7, and the mating inclined surface 6 is formed on the side of the plug 5 away from the opening 10.

[0021] The inner wall of the socket 3 is provided with a locking structure at the locking position, and the plug 5 is provided with a corresponding structure that cooperates with the locking structure; the locking structure is a locking block 11 or a locking groove 12, and the corresponding structure is a corresponding locking groove 12 or a locking block 11. In this embodiment, the upper part of the locking block 11 is provided with an inlet inclined surface 13. The locking block 11 is preferably disposed on the inner wall of the socket 3, and the locking groove 12 is preferably disposed on the plug 5.

[0022] The power supply box 1 has the aforementioned connectors on both sides along its length; the control box 2 has connectors on both sides along its length that mate with the connectors, ensuring the stability of the connection between the two boxes.
