からなっている。An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a partial plan view of a base side wall showing attachment of a terminal block, FIG. 2 is a perspective view showing a space formed in the base side wall, and FIG. 3 is a screw tightening plate housed in the space. It is a perspective view, and the same portions as those of the conventional one shown in FIGS. 4 and 5 are denoted by the same reference numerals. In the figure, (10
5) is a space formed in the side wall (103) of the base and covers (10
There is an opening on the mating surface (106) with the 2). Reference numeral (6) is a screw tightening plate made of a suitable material such as iron or an insulating material, which is to be housed in the space (105), and has a screw hole (60
1) is formed. The space (105) is substantially equal to the vertical dimension of the base of the screw tightening plate (6) (that is, the dimension in the direction from the power source side end of the circuit breaker or the circuit breaker toward the load side end) as shown in FIG. A screw tightening plate accommodating portion (105A) having a vertical dimension of the base and a width size (that is, a size viewed in the width direction of the circuit and the circuit breaker) substantially equal to the thickness of the screw tightening plate and a mounting screw ( 5) A screw relief portion (105B) for accommodating the tip end thereof.

ることもない。For mounting the terminal block (3), the screw tightening plate (6) housed in the screw tightening plate housing (105A) is mounted on the side wall (103) of the base.
Corresponding to the screw hole (601) of
Form 7). Next, screw through hole (30
1), the mounting screw (5) is screwed into the screw hole (601) of the screw tightening plate (6) through the screw insertion hole (107) of the base side wall (103). In this way, the terminal block (3) is attached to the base side wall (103).
The cutting that occurs when opening the screw insertion hole (107) in 3) only enters the space (105) and not the case (1), so there is no contact failure due to cutting, and mounting The screw (5) is not screwed into the screw hole (601) of the screw tightening plate (6) in the space (105) and does not project into the case (1), so that a sufficient insulation distance is secured. Since the screw tightening plate accommodating portion (105A) of the space (105) has substantially the same size as the screw tightening plate (6),
The screw tightening plate (6) is firmly held in the screw tightening plate accommodating portion (105A), so that the mounting screw (5) can be screwed into the screw hole (601) of the screw tightening plate (6). Easy to do. Furthermore, since the space (105) is formed only in the base side wall (103), the cover (102) does not need to be specially processed for mounting the terminal block (3), and therefore the manufacturing is simple. Since the space (105) is locally formed with a minimum size for accommodating the screw tightening plate (6), the mechanical strength of the base side wall (103) may be impaired by the space (105). Absent.

切削加工は不要であり切削が発生することはない。In the above embodiment, the screw insertion hole (107) is formed in the side wall (103) of the base when the terminal block (3) is attached. However, this screw insertion hole (107) is a so-called stupid hole. However, it may be formed in advance when the base (101) is molded. In that case, cutting of the screw insertion hole (107) is not necessary and cutting does not occur.

こともない等の諸々の効果が奏される。As described above, according to the present invention, the terminal block is clamped and fixed to the screw tightening plate in the space formed on the base side wall, so that the terminal block mounting screw insertion hole is formed on the base side wall. Even if the cutting process is performed, the cutting only enters the space and does not penetrate into the inside of the case, and the contact failure due to cutting does not occur, and the mounting screw does not protrude inside the case. In addition to ensuring a sufficient insulation distance from the charging part inside the case, the screw tightening plate is accommodated in the screw tightening plate accommodating part of the space that almost exactly accommodates this, so the terminal block The workability of the installation work is good, and since the cover does not need to be specially processed to mount the terminal block, it is easy to manufacture.
Since the space is locally formed with a minimum size,
There are various effects such that the mechanical strength of the side wall of the base is not impaired by the space.
