The present invention relates to a terminal block and a meter capable of an uninterruptible construction, and more particularly, to form a terminal housing to be detachable from the terminal block coupled to the electricity meter, even when the meter and terminal housing are separated when replacing the meter, left, right of the sliding pin By configuring the closed circuit by movement, it can maintain the uninterrupted state and at the same time can not reduce the risk of electric shock and contact accident because it is not in contact with the live wire, and the terminal housing including the sliding pin can also be moved and detached from the terminal housing for use. And a plurality of sliding pins of the first inlet, the second outlet, and the additional terminal housing of the terminal housing, and the terminal block and the meter which can be applied to the three phase as well as the single phase.

In general, the electricity meter is a gauge installed to visually check the power used in a factory, a home, or a self-employment place.The electricity meter is a mechanical method of rotating a circular measuring plate by receiving voltage and current of a power line while being connected in series with the power line. A digital method of expressing numerical values is used.

Conventional power meters are made of polycarbonate synthetic resin having a thickness of 3 mm or more having impact resistance, flame retardancy, and weather resistance. The types of power meters are small and single-phase three-wire and three-phase three-wire, and three-phase four-wire all used for single-phase two-wire capacity. There is a medium type used for the capacity, and the box is formed in the outer shape, integrally formed in the lower side of the housing with the measuring plate in the inner space, and has a terminal block having a plurality of terminal grooves into which the load and supply wires are fitted. have.

Fix the wattmeter through the fastening means such as bolt to the power use place, insert the exposed part of the load side wire and the supply side wire into the terminal groove of the terminal block, and fasten the bolt installed in the terminal block. Will be displayed through the instrument panel.

However, in the structure of the terminal block integrally formed on the lower side of the housing of the conventional electricity meter, the wires are in contact with each other in the process of inserting or drawing the exposed portion of the wire into the terminal groove of the terminal block when replacing the electricity meter due to some termination, extension, and instrument breakdown. There was a problem that a large human accident could occur due to a burn on the face or the front exposed area due to the meter explosion.

That is, in the conventional wattmeter terminal block, the terminal conductors in the terminal grooves formed in the terminal block are installed adjacent to the inlet side of the terminal groove, so that they are in contact with adjacent wires when the wattmeter is replaced.

In order to solve this problem, there is a method of "off" the cutoff switch of the electricity meter and placing it in an electrostatic state, and then inserting or drawing the exposed part of the wire into the terminal groove of the terminal block. There was another problem that caused the inconvenience to not supply.

That is, in the current electricity meter replacement work, the power outage is taken out, the exposed part of the wire is drawn out, and the electricity meter replacement work is performed.

In carrying out the above work, since the work is performed inside the collective weighing box or the single measuring box where the place is narrow due to site conditions, there is a problem that a long power outage and a large manpower accident may occur. In addition, referring to Figure 1 showing a plan view of a conventional power meter box structure, the mounting plate 150 of the instrument box and the mounting hole 142 for fixing to the contrast material, and without removing the electricity meter 140 in the mounting plate 150 Conductive prevention screw groove 143 formed in the center so as not to be removed from the contrast material, and the wiring cable inlet 144 through which the wire 141 connected to the electricity meter 140 passes.

However, the structure of the instrument box mounting plate 150 as described above is integral with the electricity meter 140 and the wire 141 to pass through the inlet 144 of the mounting plate 150 when the replacement of the instrument box There is a problem that a power failure occurs by being separated.

In addition, the worker has a risk of exposure to the live part, there is a problem of cost and time consumption due to the detachment of the electricity meter.

The present invention has been made to solve the above problems, an object of the present invention is to separate the terminal block coupled to the electricity meter, the meter replacement by configuring a closed circuit in the additional terminal housing due to the left and right movement of the sliding pin It maintains an uninterrupted state at the same time and reduces the risk of power failure by not touching live lines, thereby enabling safe installation and shortening replacement time, thus providing terminal blocks and meters that can be uninterrupted without inconvenience to customers. There is.

In addition, another object of the present invention is to be detachable to the additional terminal housing, it can be easily used to carry the additional terminal housing, by forming a plurality of first inlet, second outlet and sliding pin single phase In addition, to provide an uninterruptible terminal block and meter that can be applied to three phases.

The present invention for solving the above problems in the terminal block of the wattmeter installed in the outdoors, the first inlet and the second inlet and the customer coupled to the insertion piece formed in the wattmeter, the power supplied from the power supply source It consists of a terminal portion consisting of a first outlet portion and a second outlet portion for outputting the electric power, and a common line that is always electrically connected to the second inlet portion and the first outlet portion, the upper housing and the lower end based on the common line A terminal housing detachable by the housing; The first inlet and the second outlet are moved to the left and right from the upper surface of the terminal housing, and one side is always connected to the second outlet, and when the insertion piece and the terminal housing are separated to replace the meter. And an additional terminal housing for forming a sliding pin to allow the detachable piece to be coupled to the connecting bolt connected to the first inlet by pushing the sliding pin to the first inlet side to electrically connect the closed circuit. The terminal housing and the additional terminal housing are formed in three phases by respectively forming a plurality of first inflow parts receiving power from a power supply source, a second outflow part outputting power to a customer, and a plurality of sliding pins moved to the left and right sides, respectively. It can be used.
