As shown in FIGS. 1 to 4, the conventional circuit breaker unit is made of a plate-shaped mounting plate 11 and a close contact with one side of the mounting plate 11 and integrally penetrated by the fastening member 25. 1 The second support 21 and the second is provided integrally by the fastening member 25 to be provided at a position spaced apart from the first support 21, a plurality of terminal busbars 30 therebetween. The support member 22 and the clip member 31 which both ends are always in contact with each other by the support means so as to hold a portion of the terminal busbars 30 are fitted to be fitted to accommodate the end of the clip member 31. The main busbar 40 of the wiring breaker 20 is composed of clip bodies 50 for guiding the connection to the clip member 31 side, respectively.

In more detail, the clip member 31 is a conductive body, and is formed in a structure in which both side surfaces are symmetrical with respect to the top surface, and end portions of both side surfaces are inclined to hold the terminal busbar 30. It is structured to make.

In addition, the support means has fitting holes 36 formed on both side surfaces of the clip member 31, and fitting protrusions 33 formed at one end of the fitting hole 36 are fitted and the other end of the clip member ( 31) is formed of an elastic member 32 in close contact with both outer surfaces of the end portion is inclined.

In addition, a bolt 34 and a nut 35, which are conductors, are fastened to the upper surface of the clip member 31 for connection with the main bus line 40 connected from the wiring breaker 20.

The first and second supports 21 and 22 have a frame shape having a substantially rectangular cross-sectional structure, and are insulators, and the terminal bus bars 30 are provided on inner surfaces facing each other to grip the terminal bus bars 30. The fitting grooves which are interposed with each other are formed to correspond to each other.

The clip body 50 is coupled to one side is integrated with the circuit breaker 20, the other side is formed with a receiving groove 55, the upper end of each of the clip member 31 is fitted, the main bus line 40 is The through hole 52 is formed to be divided into a shape corresponding to both left and right sides so that the through hole 52 is formed to have a removable structure by fitting with each other.

That is, the clip main body 50 is an insulator, and is provided between the circuit breaker 20 and the clip member 31 to connect the main bus line 40 connected from the circuit breaker 20 to the bolt of the clip member 31. It has a guide function for connecting 4-wires (R, S, T, and N) to the (34) side. Here, a three-phase four-wire wiring structure will be described as an example.

In addition, in order to integrate each clip body 50 into one unit is further provided with a bracket-shaped fixture 12 of the right angled bent integrally tightly coupled by the coupling means on both sides of the clip body 50, the coupling means is a number Of the type may be employed.

One example of the coupling means is a recessed groove 56 formed on both sides of each clip body 50 and having a screw thread on the inner circumferential surface, and one side of the fixture 12 so as to correspond to each of the coupling grooves 56. Four coupling holes (12a) is formed in the end, the end is fastened to the coupling hole (12a) and the fastening groove 56, the coupling member 60 for close contact with both sides of the clip body 50, the fastener 12 It consists of.

In addition, the fastener 12 is fixedly coupled to the mounting plate 11 side through the fixing plate 13, the fixing plate 13 is both ends of the fixing fixture 12 and the mounting plate (11) Each end is integrally coupled to the fixing fixture 12 and the clip body 50 to have a function of fixing.

Coupling plate 70 is interposed between the clip body 50 and the circuit breaker 20 is used for mutual coupling.

Referring to the operation of the prior art having such a configuration as follows.

In the conventional circuit breaker unit, the three-phase four-wire terminal bus 30 is interposed so as to be sandwiched between the fitting grooves of the first and second supports 21 and 22, and both ends of the clip member 31 are connected to the terminals. The elastic member 32 is in close contact with both outer surfaces of the clip member 31 so as to keep a part of the busbar 30 held so that both ends of the clip member 31 are always in contact with the terminal busbar 30. .

By fitting the fitting protrusion 33 of the elastic member 32 to the fitting hole 36 formed on both sides of the clip member 31, the other end having its own elasticity by elastically supporting the outer surface of the clip member 31 , Both ends of the clip member 31 is pushed toward the terminal bus bar 30 so that the contact state is always maintained.

Subsequently, when the left and right clip bodies having shapes opposite to each other are coupled to each other, a through hole 52 is formed so that the main bus line 40 passes through the left and right clip bodies, and an end portion of the clip member 31 is disposed at the other side of the lower side. An accommodation groove 55 is formed to be inserted and accommodated.

At this time, the main bus 40 of the wiring breaker 20 is connected to the bolt 34 and the nut 35 side of the clip member 31 before the left and right clip main bodies 50 are combined into one main body. Located in the through (52).
