Description

Terminal Connecting Device for Water-Hour Meter The present invention relates to a power meter terminal block connection device, and more specifically, to a power meter terminal block connection device that prevents damage to the wire portion and screw portion, as well as prevents safety accidents such as fire. Generally, electricity meters for reading power consumption are installed on the service entrances of residential or commercial buildings. Electricity supplied to residential or commercial buildings is provided from low-voltage distribution poles to the distribution boxes of the buildings, and after being measured by the meters in the distribution boxes, it is supplied through the wiring of the buildings. Electricity meters are typically mounted on walls or installed in recessed distribution boxes along with circuit breakers, and are instruments that measure and record the total amount of electricity consumed over a certain period. Electricity meters are connected to terminal blocks. Terminal blocks are equipped with multiple terminal grooves, and wires are connected to the terminals by inserting them into the grooves and tightening screws. The tightening screw comes into direct contact with the conductor of the wire, and to ensure conductivity, it must be made of low-hardness brass. However, as the tightening screw is made of brass material with low hardness, not only can the tightening screw be damaged during the process of tightening or loosening it, but there is also a problem of reduced work efficiency because separate fastening tools such as drills cannot be used and the worker must perform the work manually. Furthermore, there are problems where the repeated loosening and tightening of screws damages the wires, and safety accidents such as fires may occur due to increased resistance resulting from a reduced contact area with the screws. Therefore, there is a need to improve this.
