Terminal fittings 14 are provided in the polar space 12 partitioned by 1 and 11.
The conventional terminal device of this type, in which the terminal washer 14 abutting on the terminal was screwed with a screw 15, prevents the terminal washer 13 from rotating together with the rotation of the screw 15. The width of the pole space 12 is set to be substantially equal to the width of the terminal washer 13 so that the pole 13 is substantially in contact with the side walls 11, 11, but a plurality of pole spaces divided by the side wall like a multipole circuit breaker are provided. If the side walls 11 are to be arranged side by side, the overall size cannot be reduced unless the thickness of the side wall 11 is reduced. Therefore, the thin side wall 11 may be damaged by the force of the terminal washer 13 trying to rotate. It became something with.

金の組付操作やねじ止め操作に支障は全くない。The operation of such a terminal device is the same as that of a conventional terminal device of the type described above, but the width of the pole space is slightly larger than the width of the terminal washer. Since a gap is formed between the terminal washer and the side wall, the force of the terminal washer trying to rotate together by the rotation of the screw is not applied to the gap, so the side wall is thinned and the whole is compact. The side wall is not damaged by the terminal washer even if it is made into a long-term product. In addition, since the rear wall of the pole space is a stepped rear wall divided into a convex wall portion in contact with the terminal washer and a concave wall portion forming a margin between the terminal washer, the terminal by rotation of the screw is provided. The co-rotation of the washer is prevented by the convex wall contacting the terminal washer, so there is no need to worry about the co-rotation of the terminal washer, and half of the rear wall is a concave wall that forms a margin with the terminal washer. As a result, there is no hindrance to the assembly and screwing operations of the terminal washer.

る。The present invention will now be described in detail with reference to the illustrated embodiments. FIGS. 1 and 2 show one pole when the present invention is used for a part of a multipole circuit breaker. Reference numerals 1 and 1 denote side walls each having a pole space 2 therebetween. A terminal fitting 4 extends from the base in the pole space 2 partitioned by 1, and a terminal washer 3 is abutted on the upper surface of the terminal fitting 4, and is screwed to the terminal fitting 3 by a screw 5. And
Although the above configuration is almost the same as the conventional terminal device of this type, the present invention is characterized by the structure of the pole space 2 described later and the relationship between the terminal washer 3 and the pole space 2 provided therein.

The rear wall of this polar space 2 is in contact with the rear edge of the terminal washer 3, and the rear edge of this terminal washer 3 is in contact with the rear wall of this polar space 2. The stepped rear wall 7 is divided into a concave wall portion 7b that forms a margin so that the rear wall 7 does not move. In addition, when the convex wall portion 7a and the concave wall portion 7b are used as the screw 5, when using a common screw which is rotated rightward during fastening, the left half is the convex wall portion 7a and the right half is the concave wall portion 7b. Needless to say, it is preferable.

A terminal wall is connected to the terminal washer 3 by using a screw 5 and is used in the same manner as a conventional terminal device of this type. The stepped rear wall 7 is divided into two parts by a concave wall part 7b forming a margin so that the rear edge does not come into contact with the concave wall part 7b. Due to the thickness, even if the terminal washer 3 tries to rotate together when the screw 5 rotates, the rotation is prevented by the convex wall portion 7a of the stepped rear wall 7 and the terminal washer 3 also rotates together. The convex wall portion 7a is not damaged by the force.

A gap 6 between the inner surface of the terminal washer and the terminal washer 3
6 is formed, even if the thickness of the side walls 1 and 1 is extremely thin, when the turning force is applied to the terminal washer 3, the side wall 1 and
Since there is no possibility that the rotating power is transmitted to the side walls 1 and there is no risk of the side walls 1 and 1 being damaged, it can be used for a long period of time.

Therefore, there is no possibility of hindering the assembling operation of the terminal washer 3 and the screwing operation by the screw 5.

来のこの種端子装置の問題点を解決したものとして業界
の発展に寄与するところ大きいものがある。As is apparent from the above description, according to the present invention, the width of the pole space is made slightly larger than the width of the terminal washer to form a gap between the terminal washer and the side wall, and the rear wall of the pole space is formed. Is made into a stepped rear wall divided into two parts, a convex wall part in contact with the terminal washer and a concave wall part forming a margin between the terminal washer, thereby reducing the thickness of the side wall and miniaturizing the whole. Also, there are various advantages such that the side wall is not likely to be damaged by the force to rotate the terminal washer, and there is no hindrance to assembling operation and screwing operation of the terminal washer. Since the design change is small and the structure is extremely simple, there is an advantage that it can be mass-produced at low cost. Therefore, the present invention largely contributes to the development of the industry as a solution to the problems of the conventional terminal device of this type.
