A power failure and recovery terminal in a centralized meter box

Abstract

The invention relates to an electricity stopping and recovering binding post, and belongs to the technical field of electric conduction connection. The electricity stopping and recovering binding post comprises a first insulation outer shell with a first opening and a hollow metal bar penetrating through the first insulation outer shell. The part, in the first opening, of the hollow metal bar is provided with a wire inlet fixing bolt and a wire outlet fixing bolt, both of which penetrate through the side wall of the hollow metal bar. The first insulation outer shell extends in the direction of the hollow metal bar to form a second insulation outer shell close to a live wire outlet end. The second insulation outer shell is provided with a second opening same as the first opening in direction. The second insulation outer shell is internally provided with a hollow plastic bar penetrating through the second insulation outer shell, and the hollow plastic bar is the same as the hollow metal bar in size and is coaxial with the hollow metal bar. The part, in the second opening, of the hollow plastic bar is provided with an outage fixing bolt penetrating through the side wall of the hollow plastic bar. By means of the binding post, the purpose that the electricity of arrearage clients stops being supplied and the arrearage clients are pressed for payment safely, accurately and quickly on the premise that ammeters operate normally is achieved.

Description

technical field [0001] The invention relates to a connection terminal for power failure and recovery in a centralized meter box, belonging to the technical field of conductive connection. Background technique [0002] The terminal block is generally used at the outlet end of the centralized meter box, which is the asset demarcation point between the power supply department and the customer, and the electrical equipment after the outlet line belongs to the customer's personal property. [0003] At present, the terminal structure commonly used in the work site is as follows: Figure 1-Figure 3 As shown, the live wire incoming wire 1-1 and live wire outgoing wire 2-1 are connected to the hollow metal rod 3-1, and the incoming wire fixing bolt 4-1 and the outgoing wire fixing bolt 5-1 respectively connect the live wire incoming wire 1-1 and the live wire outgoing wire 2 -1 is compressed in the hollow metal rod 3-1 to keep the conductive parts of the incoming live wire 1-1 and th...

Problems solved by technology

However, there are several disadvantages in the above method: 1) The outgoing lines of the centralized meter box are very tightly arranged, so the 10mm 2 The wires above and above are difficult to twitch, which affects the safety and stability of the operation; 2) The exposed metal part of the live wire drawn out from the centralized meter box is exposed in the meter box, and it is easy to touch the live parts in the meter box and cause danger; 3) Since the terminal is in an open state, the user can operate to restore the power supply by himself, and the power failure function cannot be effectively implemented
