The present invention relates to an aggregate terminal block capable of branching and supplying input power by installing a plurality of branch connection connection terminals connected to a conducting board in a row (vertical or horizontal).

To explain this in more detail, on the upper surface of the terminal block support block made of a long rectangular parallelepiped, a plurality of branch connection terminals connected to the current plate are installed in a row (vertical or horizontal) to assemble and install, branch connection Power input to the terminal block (+ line and - line, R line, S line, T line, N line) can be supplied by branching;

The terminal block support blocks equipped with the branch connection terminal block may be installed in two stages by the terminal block support block, and a pair of terminal block support blocks in which the branch connection terminal block is installed may be symmetrically installed;

By installing the terminal block support block in which the terminal block support block of the branch connection terminal block is installed is installed in series or parallel, wires (+ line and - line, R line, S line, T line, N line) can be branched and supplied, and branched wires ( (+ line and - line) and (R line, S line, T line, N line)) are distributed in two stages to provide an aggregate terminal block that can be installed (connected).

In general, a distribution board is installed at a place where the main line through which electricity flows is divided into each branch circuit, and various breakers such as overcurrent breakers of the branch circuit are installed, and each of the breakers is electrically connected. As a device, power is supplied from the outside It is a device that can draw in, distribute and open and close the power supply at the same time.

As for the above distribution panel, Korean Patent Publication No. 10-2001-0028785 (prefabricated distribution panel) and Registered Patent No. 10-0993099 (Power redistribution device and distribution equipment in building facilities using the same) and Registered Patent No. 10-1207093 Ho (improved instrument transformer (PT terminal block), etc. have been proposed.

The distribution board will be described with reference to FIG. 10 of the accompanying drawings.

Each input line (wire) of R line (L1), S line (L2), T line (L3), and N line (L4) is connected to the input terminal of the wiring breaker (100: MCCB), and the wiring breaker ( 100: Each output line (wire) of R1 (L1-1), S line (L2-1), T line (L3-1), and N line (L4-1) is connected to the output terminal of MCCB).

On both sides of the left and right sides of the R line (L1-1), S line (L2-1), T line (L3-1), and N line (L4-1) connected to the output terminals of the wiring circuit breaker (100: MCCB), a plurality of The single-phase power relays 110 and the like are installed in columns, and the single-phase power relays 110 on the same horizontal line in the left and right single-phase power relays 110 are R branch lines (L1-2), S branch lines (L2-2), Any one of the T branch lines (L3-1) is connected to the N branch line (L4-2), and any one of the R branch lines (L1-2), S branch lines (L2-2), and T branch lines (L3-1) is connected. is connected to each output line (electric wire) of R1 (L1-1), S line (L2-1), T line (L3-1) and contacts 60, 61, 62, and each N branch line (L4- 2) is connected to the N line (L4-1) and the contact 63.

However, the conventional distribution board as described above occupies a wide installation area, it is not easy to utilize the space, and there is a safety problem because the terminal block is exposed to the outside. There is a problem in that not only short-circuit accidents occur due to minor mistakes of technicians and ordinary people, but also burns and fire accidents occur due to short-circuit accidents.

That is, when replacing a distribution panel or carrying out maintenance work while electricity is being supplied (live wire), electricity is supplied through a transformer installed on a utility pole installed on the ground (roadside, etc.), and multiple households (houses) and Since electricity is supplied to the building, when the fuse of the transformer is opened, there is a disadvantage that power blackout (power outage) occurs in several households (houses) and buildings. Issues such as having to obtain consent for (blackout) arise.

In particular, in the terminal block (distribution panel) that is generally used, the working time is reduced by crimping the terminals with a crimping tool, insulating the terminal connection area with a terminal cap, separating the terminal block bolts, connecting the terminals, and then tightening the bolts to connect the wires. Since it takes a lot, the power outage time becomes longer, and in the case of a three-phase, four-wire or single-phase individual terminal block, there is a lot of installation space required to arrange and install several terminal blocks in series or parallel, and the terminal block is exposed, so some insulation parts must be covered with an insulation cover. Insulation is not complete in the form of padding, so it is vulnerable to safety accidents such as electric shock and short circuit (short circuit), and there is a problem that wires are arranged in a mess over a wide surface along with the terminal block in electrical wiring.

On the other hand, terminal blocks are formed in two or three stages, domestic Patent Registration No. 10-0658659 (connection terminal structure for relay terminal block), Registration Patent No. 10-1213712 (one-touch mounting type terminal block), and Registered Patent No. No. 10-1974286 (terminal block with spacing adjustment assembly structure), Registered Utility Model No. 20-0330976 (relay terminal block), Registered Utility Model No. 20-0457897 (connection terminal block for 3-phase induction motor), Utility Model Release No. 20 -2012-0002008 (terminal block) and the like are known.

These terminal blocks are installed in two or three stages of terminal units (positive terminals and negative terminals) with a plurality of terminals in an integrated terminal block block, and the terminals of the 1st, 2nd, and 3rd terminals are on the same line. Since only the located terminals are electrically connected, there is a limit in that each terminal cannot be continuously connected.

An object of the present invention is to provide an aggregation terminal block capable of solving the above problems and drawbacks.

The present invention is to provide a terminal block that can branch and supply input power to each branch connection terminal by installing a plurality of branch connection terminals connected to a current board in a row while maintaining a constant interval inside the branch connection terminal block,

The terminal block is assembled and installed with a plurality of branch connection terminals mounted in a row (vertical or horizontal) on the upper surface of the terminal block support block, which is a long rectangular parallelepiped, connected to the current plate, and inputs to the branch connection terminal block It is possible to supply power (+ line and - line, R line, S line, T line, N line) by branching;

The terminal block support blocks equipped with the branch connection terminal block may be installed in two stages by the terminal block support block, and a pair of terminal block support blocks in which the branch connection terminal block is installed may be symmetrically installed;

Another object of the present invention is to provide many connection terminals in a small space with a compact structure so that it can be easily installed in a small installation area, space utilization can be facilitated, and connection lines can be more than doubled compared to single-layer terminal blocks. And most of the terminal blocks are sealed to provide a set terminal block that is safe from electric shock or short circuit.

In particular, it is a terminal block installed on the primary side receiving electricity from the outside of the building. Even if most of the work is performed while the electricity is live (supply) during periodic electric meter replacement or maintenance, there is no exposed terminal part, so there is no power failure from short circuit. Loss of life and property due to burns and fire accidents can be prevented from the source, and blackout accidents due to fire or burns can be prevented from the source. The task is completed by simply tightening with a screwdriver, so the work is simple and the power outage time can be reduced, thereby providing an economical and safe terminal block.

Another object of the present invention is to optimize and integrate terminal blocks of multiple phases (R, S, T, N) into stacks to have complete insulation performance while installed inside the insulation case, and to have a wide space as a compact structure. Wire connection can be made smoothly without need, and even if the single-phase connection circuit is increased, the capacity is doubled just by connecting a c-shaped connection connector, so it can be easily expanded without connecting a terminal block. As a result of saving, the size of the concrete embedment is reduced, so in the case of a load-bearing wall of reinforced concrete, it can contribute to the increase of the load-bearing structure of the building due to the increase in the area of reinforced concrete in the case of a load-bearing wall. With the installed structure, it is possible to solve the phenomenon of overlapping wire connection locations and interference, and since the connection parts for power supply and terminal block extension are located on both sides and lead-in holes are formed on the front and side, the lead-in line can be extended or An object of the present invention is to provide an assembly terminal block that can be easily straightly bound to a front or side hole without the hassle of bending.
