Description

Uninterruptible Terminal Blocks {TERMINAL BOARD FOR UN-STOPPAGE POWER SUPPLY}

The present invention relates to a terminal block that allows a power meter to be replaced in an uninterruptible state.

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.

Hereinafter, an uninterruptible terminal block according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 8.

As shown, the uninterruptible terminal block according to the present invention includes a fixed terminal block 40, a connecting pin 50.

The present invention can be used for both single-phase and three-phase electricity meter, and will be described based on three phases for convenience of description.

The fixed terminal block 40 has a multi-layered structure consisting of a two-layer structure of the upper layer 30 and the lower layer 20, first, looking at the lower layer 20,

A plurality of connecting pins 11 protruding from one end of the electricity meter 10 are fitted to the upper end of the lower layer 20, and the lower end of the lower layer 20 is divided into two compartments. The first inlet portion 21 to which the inflow line 61 supplied with electric power from 60 is connected, and the power passed through the electricity meter 10 after being introduced through the first inlet portion 21 to the customer 70. The first outlet 22 is connected to the supply line 71 for supplying. Of course, as described above, since the present description is based on a three-phase power meter, the first inflow portion 21 includes four lines a, b, c, and d in the lower layer 20 of the fixed terminal block 40. The first outlet 22 is also made of four lines (e, f, g, h) in the lower layer 20 of the fixed terminal block (40). In addition, each of the first inlet portion 21 and the first outlet portion 22 should be made of a plurality of copper pipes spaced at equal intervals from each other to allow electricity to flow through the corresponding line. (The same applies to the second inlet portion 31 and the second outlet portion 32, which will be described later.)

In other words, the four inflow lines 61 flowing from the power supply unit 60 are connected to the first inflow unit 21 of the fixed terminal block 40, respectively, and the power supplied thereto passes through the electricity meter 10. The second outlet 32 flows to the customer 70 through the supply line 71. (Of course, of the four lines of the first inlet 21 and the first outlet 22, each one of the lines (d, h) must be always connected to each other through the common line (23) Is natural.)

Looking at the top layer 30,

The upper layer 30 is formed to protrude on the upper surface of the lower layer 20, and the upper layer 30 has a second inlet portion 31 corresponding to the first inlet portion 21 of the lower layer 20. ) And a second outlet portion 32 corresponding to the first outlet portion 22 are formed. In addition, the first and second inlet portions 21 and 31 and the first and second outlet portions 22 and 32 which are positioned in a plurality of layers on the upper and lower ends thereof are connected to each other so that electricity can flow therethrough. (In part of FIG. 3) (In other words, since the first and second inflow portions 21 and 31 and the first and second outlet portions 22 and 32 are all made of copper tubes, the first inflow portion It is preferable to connect the 21 and the second inlet part 31 with each other and between the second outlet part 22 and the second outlet part 32 with copper of the same material. The first inlet portion 21 and the second inlet portion 31 are connected to each other, and the first outlet portion 22 and the second outlet portion ( 32) is connected. As described above, since the first inlet 21, the second inlet 31, the first outlet 22, and the second outlet 32 all consist of a plurality of lines, a plurality of first The first inflow portion 21 and the first inflow portion 21 corresponding to the up and down, the first inflow portion 21 corresponding to the upper and lower, or the first, the top and bottom Only the outlet 22 and the second outlet 32 is connected.

In addition, the first and second inlets 21 and 31 and the first and second outlets 22 and 32 may be connected to the common line 23 so that the fixed terminal block 40 may be coupled to the three-phase electricity meter as described above. By forming each of the four lines including one line that is always connected to each other by a single phase, the three-phase fixed terminal block 40 for single-phase without having to separately manufacture a fixed terminal block 40 used for single-phase for single-phase power meter It can be used for.

As described above, the connecting pin 50 is used to replace the electricity meter 10 used by combining the fixed terminal block 40 of the multilayer structure with the single-phase or three-phase electricity meter.

The connecting pin 50 has a '∪' shape of the connection line 51 is a single phase, one inside, in the case of a three-phase so that a plurality is formed therein.

That is, when a case where the power meter 10 needs to be replaced, the coupling pin 50 may be fitted to correspond to one end of the upper layer 30, and the connection formed inside the connection pin 50. One end of the line 51 is connected to the second inlet 31, and the other end of the connection line 51 is connected to the second outlet 32. (For this purpose, it is natural that both ends of the connecting pin 50 should be formed to protrude toward the fixed terminal block 40 side.)

In other words, when the three-phase electricity meter is replaced, each of the plurality of connection lines 51 has one end connected to each of the plurality of second inlets 31, and the other end of each of the plurality of second outlets ( 32) respectively.

Thus, the power flowing into the first inlet 21 of the fixed terminal block 40 flows to the second inlet 31, the power to the second inlet 31 through the connection line 51 Since the flow to the second outlet 32, the power flow to the second outlet 32 is moved to the first outlet 22 is supplied to the customer 70 through the supply line 71 It becomes an uninterrupted. That is, the power from the first inlet part 21 to the first outlet part 22 via the wattmeter 10 is passed through the wattmeter 10 through the connection line 51 of the connecting pin 50. It flows directly from the first inlet 21 to the first outlet 22.

In addition, the reference numeral '12' of the drawings not described above is a fixing means such as a bolt, etc., the connecting pin 11 and the inlet line 61 and the supply line 71 or the inner line in the lower layer 20 It is for fixing both ends of the connection line 51 of the connecting pin 50 to be fitted to the upper layer 30, and the upper and lower layers 20 and 30 to which the fixing means 12 are fitted are corresponding thereto. Naturally, the connection hole (not shown) to which the fixing means 12 is fixed should be formed in a perforation.
