The connecting plate 11 can be attached to the terminal base 12 by two methods. That is, normally, as shown in FIG. 3, the leg piece 1 is attached to the attachment piece 11c.
The coupling plate 11 is fixed to the protrusion 15 in a form in which the surface opposite to the surface from which 1b protrudes is brought into contact with the lower surface of the protrusion 15. On the other hand, as shown in FIG. 4, the joint plate 11 can be fixed to the protrusion 15 by inserting the protrusion 15 between the leg pieces 11b. Here, the height from the lower surface of the terminal base 12 to the lower surface of the coupling plate 11 when the coupling plate 11 is attached to the terminal base 12 in the form of FIG. 3 is H1, and the coupling plate 11 is the terminal in the form of FIG. If the height from the lower surface of the terminal base 12 to the lower surface of the coupling plate 11 when attached to the base 12 is H2,
H1 <H2. Therefore, the body 21 and the cover 2
It is possible to deal with two types of body 20 having different height positions of the divided surface with respect to two with one type of member. In addition, in the state of FIG. 4, the internal electric wire 3 is connected to both the leg pieces 11b.
It suffices to pass it between the stand 15 and the stand 15.

が可能になるという利点を有する。According to the first aspect of the present invention, the connecting plate is attached to the terminal base so that a part of the connecting plate protrudes from the opening window formed on the surface of the terminal base opposite to the body of the circuit breaker. Since the pair of holding pieces are provided on the coupling plate so as to fit into the holding grooves formed on both sides of the coupling hole formed on the body of the circuit board, The terminal base can be connected to the body by fitting it into the holding groove provided in the body of the circuit breaker. In addition, the coupling plate includes a pair of leg pieces that are provided in the terminal base with a holding piece at the tip, and a protrusion that is formed on the inner surface of the terminal base by continuously connecting both leg pieces together. The holding groove is formed on both sides of the coupling hole, so the internal wire can be passed between the holding pieces fitted in the holding groove. It is possible to mechanically connect the terminal base and the body by utilizing the opening through which the electric wire is passed. That is, it is possible to sufficiently increase the mounting strength while relatively reducing the facing area between the terminal base and the body.
The invention of claim 2 has an advantage that the area of the opening for inserting the internal electric wire can be made sufficiently large. According to the invention of claim 2, the protrusion formed on the inner surface of the terminal base is inserted between the two leg pieces. Shape, so that the mounting piece can be connected to the stand,
Since the width of both legs is set larger than the width of the stand,
The connecting plate can be attached to the protrusion in such a manner that one of the surface of the mounting piece on which the leg piece projects and the surface on the opposite side of the mounting piece are in contact with the protrusion. That is, there is an advantage that the positional relationship between the body and the terminal base can be changed by changing the mounting method of the coupling plate, and it is possible to cope with two types of bodies having different sizes.

路遮断器の補助端子台。1. A terminal base for a hollow terminal base attached to an outer surface of a body of a circuit breaker, and an internal wire attached to the terminal base and pulled out from the inside of the body of the circuit breaker. Part of the terminal that connects to the inner space of the terminal and that connects the external electric wire that is wired to the outside of the terminal base, and the opening window that is formed on the surface of the terminal base that faces the body of the circuit breaker As described above, the body of the circuit breaker includes a body having an opening on one side and a cover detachably coupled to the body so as to cover the opening of the body. At least one of the body and the cover is formed with a coupling hole that is open so as to face the dividing surface between the body and the cover and has retaining grooves on both side surfaces, and the coupling plate has a pair of retaining pieces fitted into the retaining grooves. And each holding piece at the tip and arranged facing each other And a pair of leg pieces that are substantially parallel to the opening surface of the body and are detachably attached so as to face the protrusion formed on the inner surface of the terminal base by integrally connecting both leg pieces. And an auxiliary terminal block for a circuit breaker, wherein the leg piece is provided so as to project in a direction opposite to a surface of the mounting piece facing the projecting stand.
