Metering terminal box

Abstract

The invention discloses a metering terminal box capable of effectively solving problems of wire off and wire breaking in wiring and ensuring safe operation of an electric power circuit. The metering terminal box comprises a box body, a box cover, conducting strips and a locking mechanism. The interior of the box body is partitioned into a plurality of wiring cavities through longitudinal partition plates, a boss is arranged in the middle of each wiring cavity, a left side face and a right side face of the front portion and a left side face and a right side face of the rear portion of each wiring cavity are respectively and correspondingly provided with a hinged seat, and wiring holes respectively corresponding to the wiring cavities are formed in the front side wall and the rear side wall of the box body; a sleeve hole adaptive to the boss is formed in the middle of each conducting strip, and the conducting strips are correspondingly arranged at bottoms of the wiring cavities one by one; the locking mechanism comprises gate valves, springs and baffles, each gate valve comprises a pressing handle, a valve block and a hinged shaft, and the gate valves are mounted on the front portion and the rear portion of each wiring cavity of the box body; the springs are arranged the pressing handle of each gate valve and the boss in an embedded mode; and pressing handle holes respectively corresponding to the pressing handles of the gate valves are formed in the front portion and the rear portion of each baffle, and middles of the baffles are mounted on the bosses through screws.

Description

technical field [0001] The invention relates to a metering junction box. Background technique [0002] The metering junction box is a special junction box in the standard junction box of the electric energy metering device. It is also suitable for the secondary circuit with a rated voltage up to 660 volts and a rated current up to 20A. Instruments, leakage protection and other electrical equipment, to ensure the safety of personal operation, improve the efficiency of on-site work. The current metering wiring is fixed and connected by a single small wire screw, which is cumbersome to operate, poor in safety, and prone to errors. [0003] Foreign metering wiring is good in quality and high in safety, but it cannot fundamentally change the disadvantages of cumbersome installation and easy installation errors. [0004] Although the socket interface is convenient to work, it cannot change the disadvantages of installation errors and poor security. Contents of the invention ...
