Embodiment 1
[0046] This embodiment provides a connection terminal for replacing a single-phase electric energy meter without power failure. The connection terminal treasure includes a terminal box and a meter replacement plug, respectively as figure 1 with figure 2 shown.
[0047] figure 1 A top view of a terminal box for replacing a terminal box of a single-phase electric energy meter without power failure provided by an embodiment of the present application.
[0048] Such as figure 1 As shown, the terminal box 100 for replacing the connecting terminals of a single-phase watt-hour meter provided by this embodiment includes four connecting units 10, which are the first connecting unit 11, the second connecting unit 12, and the third connecting unit from left to right. unit 13 and the fourth communication unit 14 .
[0049]Each communication unit includes an upper clip 111, a lower clip 113, and a socket 112 between the upper clip 111 and the lower clip 113. The socket 112 is provided...
Embodiment 2
[0068] Figure 7 It is a top view of the upper cover provided by another embodiment of the present application.
[0069] In this embodiment, an upper cover 300 is added on the basis of the previous embodiment. Such as Figure 7 As shown, the upper cover 300 is fixed on the upper surface of the terminal box, and is used to cover the communication units of the terminal box to increase safety.
[0070] The shape of the upper cover 300 matches the shape of the terminal box, and four through holes 30 are arranged on it. The hole 30 is inserted into the socket of the communication unit.
[0071] The upper cover is also provided with a number of circular through holes, the positions of which are respectively matched with the compression screws of the upper and lower clamps of the communication unit, so as to facilitate loosening or tightening of the compression screws during wiring.
[0072] In order to prevent electricity theft, an outer cover 400 can also be set, such as Figu...

Abstract
The embodiment of the invention provides a binding post enabling a single-phase watt-hour meter to be replaced without a power cut. The binding post enabling the single-phase watt-hour meter to be replaced without a power cut comprises a terminal box and a meter replacement plug. The terminal box is provided with four connecting units. Each connecting unit is provided with an upper clamping piece, a lower clamping piece and a jack located between the upper clamping piece and the lower clamping piece, an upper metal dome and a lower metal dome are arranged in the jack, the upper metal dome is connected with the upper clamping piece, the lower metal dome is connected with the lower clamping piece, and the upper metal dome is in contact with the lower metal dome. The meter replacement plug is provided with four metal male tabs. The four metal male tabs are matched with the four jacks. The meter replacement plug is used for being plugged into the terminal box. When the meter replacement plug is plugged into the terminal box, an incoming live wire is in short circuit connection with an indoor live wire, an incoming null line is in short circuit connection with an indoor null line, and electricity utilization of resident users cannot be influenced no matter what kind of operation is conducted on the single-phase watt-hour meter at this time; besides, the problem that interruption of power supply of the resident users is caused by an existing replacement mode is solved.
Description
technical field [0001] The present application relates to the field of electric power technology, and more specifically, relates to a connection terminal for replacing a single-phase electric energy meter without power failure. Background technique [0002] With the rapid development of my country's economy, the demand for electricity in all walks of life is increasing. At the same time, the requirements of power customers for the service level of power companies are also constantly increasing. The State Grid Corporation of China even put forward the "Ten Commitments for Power Supply Services" to provide services for residential users with different natures of electricity consumption in different regions. Among them, the regulations for emergency repairs of electricity: urban areas shall not exceed 45 minutes, and rural areas shall not exceed 90 minutes. It is not more than 3 hours in remote areas; it is also stipulated that for residential users who install meters and rece...
