[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, the socket with a pluggable three-phase 485 meter includes a bottom shell 1 and a top cover 2 that cooperate with each other. A circuit board 7 is installed inside the bottom shell 1. Multiple circuit boards 7 can be arranged longitudinally, and an anti-reverse mechanism 8 is installed at the bottom of the circuit board 7.

[0019] Connection holes 11 are provided on both sides of the bottom shell 1.

[0020] Above the top circuit board 7 are a communication interface 3, buttons 4, indicator lights 5, and a display screen 6. All four are connected to the circuit board 7. The communication interface 3 uses the 485 protocol. There are two communication interfaces 3, one for input and the other for output, allowing two sockets to be connected sequentially for communication. Two buttons 4 are located on one side of the communication interface 3, serving as page navigation on the display screen 6. Three indicator lights 5 are located on one side of the communication interface 3 and buttons 4, displaying the socket's operating status. The display screen 6 is located on one side of the indicator lights 5 and displays the socket's functions. If a single page does not display all functions, users can use buttons 4 to navigate up and down.

[0021] The top cover 2 is provided with a first hollow part 21, a second hollow part 22, a third hollow part 23 and a fourth hollow part 24 that respectively cooperate with the display screen 6, the communication interface 3, the indicator light 5 and the button 4.

[0022] The top cover 2 has protrusions on both sides, and through holes opposite to the connection hole 11 on the protrusions. The top cover 2 can be fixed to the bottom shell 1 by screws passing through the through holes and the connection hole 11. At the same time, the bottom shell 1 is also fixed to the socket by screws passing through the connection hole 11.

[0023] The bottom shell 1 may also be equipped with a current transformer (not shown in the figure) for detecting whether the current and voltage are overloaded.

[0024] The meter in this socket is a three-phase meter with single-phase power supply, but it can realize three-phase power input. It can supply power regardless of which phase is input. A three-phase detection chip is set on the circuit board 7 to detect which phase is supplying power.

[0025] This utility model features a socket with a pluggable three-phase 485 meter. By setting buttons 4, indicator lights 5, and a display screen 6 on the circuit board 7, and by using buttons 4 to turn pages on the display screen 6, the socket's working status and functions are displayed, making it easy for users to know the power usage.

[0026] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
