[0002] During the implementation of power projects, circuit testing and routine maintenance often require temporary wiring or the addition of control switches to meet the circuit regulation needs under specific operating conditions, in order to ensure the smooth progress of testing and the efficient advancement of maintenance work. Such operations have become an indispensable routine process in the field of power engineering.

[0003] However, traditional power wiring switches use a connection method where the line is directly connected to the switch body. When performing wiring operations in complex wiring environments, operators need to directly touch and comb multiple wires. Due to limited operating space and messy wire arrangement, live wires are prone to come into contact with each other, which can lead to electric shock, short circuits and other safety accidents, posing a serious threat to the personal safety of operators.

[0004] Given the high risks to personal safety and low operational efficiency of existing technologies, there is an urgent need for a new type of power supply auxiliary device to solve these problems. Therefore, this invention proposes a safe, portable power supply base. Summary of the Invention

[0045] This application provides an embodiment of a safe portable power supply dock, please refer to the following for details. Figure 1 and Figure 2 .

[0046] The safe portable power supply base in this embodiment includes: a housing 1, in which multiple switch components 2 are detachably installed; and a connection component 3 for connecting to an external power grid is provided on the housing 1. The number of connection components 3 is equal to the number of switch components 2, and they are arranged in a one-to-one correspondence. Each connection component 3 includes an inlet terminal and an outlet terminal. Each inlet terminal is electrically connected to its corresponding switch component 2 through a wiring connector, and each outlet terminal is electrically connected to its corresponding switch component 2 through an outlet connector.

[0047] It should be noted that this safe portable power supply base consists of a housing 1 containing multiple detachable switch assemblies 2 and an equal number of corresponding connecting assemblies 3. Each connecting assembly 3 is further divided into independent inlet and outlet terminals, which are then electrically connected to the corresponding switch assembly 2 via dedicated wiring connectors. This modular and standardized connection architecture fundamentally changes the traditional direct wiring method, allowing external circuit connections to be made through structurally separated and fixed standardized interfaces. This effectively avoids the risk of live wires coming into contact with each other due to handling complex and messy cables, significantly improving the personal safety of operators. At the same time, this structure lays the foundation for the rapid and independent installation, removal, and replacement of switch assemblies 2, eliminating the need to touch other circuits or disconnect the main power supply when maintaining or replacing a switch. This greatly reduces production interruption time caused by power outages and improves the overall efficiency of power operation and maintenance.

[0048] The above is Embodiment 1 of a safe portable power supply dock provided in this application. The following is Embodiment 2 of a safe portable power supply dock provided in this application. Please refer to the following for details. Figures 1 to 4 .

[0049] The safe portable power supply base in this embodiment includes: a housing 1, in which multiple switch components 2 are detachably installed; and a connection component 3 for connecting to an external power grid is provided on the housing 1. The number of connection components 3 is equal to the number of switch components 2, and they are arranged in a one-to-one correspondence. Each connection component 3 includes an inlet terminal and an outlet terminal. Each inlet terminal is electrically connected to its corresponding switch component 2 through a wiring connector, and each outlet terminal is electrically connected to its corresponding switch component 2 through an outlet connector.

[0050] Understandably, during the installation process, the housing 1 is first installed in a suitable position, and then the circuit to be added is connected through the incoming and outgoing terminals. This enables the external circuit to be electrically connected to the internal switch assembly 2, thereby enabling the switch assembly 2 to control the external circuit.

[0051] The switch assembly 2 includes a switch body 21, a mounting bracket 22, a first limiting member 23 for guiding and limiting the wiring connector, and a second limiting member 24 for guiding and limiting the outgoing wire connector. The mounting bracket 22 is detachably installed inside the housing 1, and the switch body 21 is detachably installed on the mounting bracket 22. One end of the switch body 21 is provided with a wiring port 25 for cooperating with the wiring connector, and the other end is provided with an outgoing wire port 26 for cooperating with the outgoing wire connector. The first limiting member 23 is located at one end of the wiring port 25 and is detachably connected to the switch body 21. The second limiting member 24 is located at one end of the outgoing wire port 26 and is detachably connected to the switch body 21. The switch body 21 is provided with a switch button 27 for closing or opening the internal circuit.

[0052] One end of the wiring connector is electrically connected to the incoming terminal, and the other end is provided with a copper terminal for insertion into the terminal 25; the wiring connector is electrically connected to the switch assembly 2 through the copper terminal; one end of the outgoing connector is electrically connected to the outgoing terminal, and the other end is provided with an outgoing copper terminal for insertion into the outgoing port 26; the outgoing connector is electrically connected to the switch assembly 2 through the outgoing copper terminal.

[0053] It should be noted that the size of the connection port 25 is set slightly smaller than the size of the connection copper post, and the size of the outlet port 26 is set slightly smaller than the size of the outlet copper post. This allows the copper posts (connection copper post / outlet copper post) to be slightly compressed during installation, thereby generating greater friction. This interference fit design ensures a tight connection between the copper post and the socket, preventing loosening or detachment due to vibration or external force, achieving a tighter connection. After connection, the circuit can be closed or opened via the switch button 27.

[0054] Preferably, a power-off protection component 4 for power-off protection of the circuit is detachably connected to the switch body 21. By setting the power-off protection component 4, the circuit can be cut off in time in the event of a short circuit or open circuit, thus protecting personal and property safety.

[0055] Preferably, the switch body 21 is also provided with a signal indicator 5 for displaying the three-phase wiring status. Specifically, the signal indicator 5 can display a green indicator when the three-phase lines are connected at the incoming and outgoing ends, a red indicator when not connected, and a yellow indicator when the connection is unstable and intermittent, indicating a potential fault risk; the three different indicator lights can effectively alert the operator.

[0056] The incoming terminal is a connector for connecting external circuit wires; the outgoing terminal is a connector for connecting external circuit wires.

[0057] Preferably, a fixing component for preventing the switch body 21 from becoming loose is detachably installed inside the housing 1.

[0058] It should be noted that when the switch assembly 2 is installed inside the housing 1, it can be further fixed by the fixing component to prevent the switch assembly 2 from shifting due to environmental factors (such as vibration), thereby further increasing the adaptability to different scenarios.

[0059] A snap-fit ​​groove 28 is provided on one side of the switch body 21. The fixing component includes a snap-fit ​​block for snap-fitting with the snap-fit ​​groove 28 and a compression spring for making the snap-fit ​​block tightly abut against the snap-fit ​​groove 28. One end of the compression spring is connected to the housing 1 and the other end is connected to the snap-fit ​​block.

[0060] It is understandable that by snapping the locking block into the locking groove 28 on the side of the switch body 21, shaking can be prevented and unstable wiring can be avoided.

[0061] The housing 1 has a mounting groove 11 for accommodating the switch body 21, and a fixing component is disposed within the mounting groove 11. Specifically, one end of the compression spring is detachably connected to the inner wall of the mounting groove 11, and the other end is fixedly connected to the snap-fit ​​block.

[0062] The housing 1 can be equipped with an openable transparent dust cover, which can protect the switch assembly 2 while allowing the working status of the internal switch assembly 2 to be clearly seen, thereby further increasing the adaptability to different scenarios.

[0063] This safe portable power supply base connects the wires of the external circuit to be controlled via the connecting component 3 on the housing 1. During operation, it effectively avoids the risk of contact between corresponding live wires, thus ensuring the personal safety of the operator. In actual control, multiple switch components 2 can be set inside the housing 1 to achieve different functions. At the same time, the switch body 21 of the switch component 2 is equipped with a power-off protection component 4 for short circuit and circuit breaking protection, further effectively protecting personal safety. In addition, the switch body 21 is equipped with a signal indicator 5, which can clearly show whether the circuit is connected properly, saving inspection costs, reducing production interruptions and economic losses caused by power outages, and reducing maintenance costs in the long run.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
