Abstract

PROBLEM TO BE SOLVED: To provide a terminal device of a breaker where the width of the breaker is made thinner and a panel board can be miniaturized. SOLUTION: At both end sides of a case 2, a terminal device 3a of the first electrode and a terminal device 3b of the second electrode are mutually shifted in the inserting direction of an electric wire 4, and further mutually shifted vertically with respect to the insertion direction of the electric wire 4.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device for a breaker. 2. Description of the Related Art In recent years, distribution boards have become multi-circuited with the increase in electrical equipment. However, the size of distribution boards has been reduced in size so that they can be installed in narrow spaces. In a distribution board 11 generally used for home use, as shown in FIG. 3, a conductive bar 13 extending in the lateral direction of the main breaker 12 is connected to the secondary side of the main breaker 12, A branch breaker 14 is connected. Therefore, as the number of circuits increases, the size of the distribution board 11 increases horizontally. As shown in FIGS. 4 and 5, the conventional branch breaker 14 has a first pole terminal device 16a and a second pole terminal device 16b arranged side by side at the end of a case 15. However, in this branch breaker 14, since the width of the case 15 is large, the terminal device 26a of the first pole and the terminal device 26b of the second pole are shifted in the height direction of the case 25 as shown in the breaker 24 shown in FIG. Some were reduced in size. [0003] The terminal device 26a, 26
Although the width of the breaker 24 whose b is shifted in the height direction is small, the width is only slightly reduced because a space for inserting a driver 28 for turning the terminal screw 27 is required. [0004] In view of the above problems, an object of the present invention is to provide a terminal device for a breaker that can reduce the width of the breaker and reduce the size of the distribution board. [0005] In order to achieve the above object, in a breaker provided with a two-pole terminal device on at least one side of a case, each of the terminal devices is shifted in a wire insertion direction, In addition, it is characterized by being arranged vertically displaced with respect to the wire insertion direction. [0006] A first case is provided on at least one side of the case.
The terminal device of the pole and the terminal device of the second pole are displaced from each other in the insertion direction of the electric wire, and are further displaced from each other in the vertical direction with respect to the insertion direction of the electric wire. An embodiment of a terminal device for a breaker according to the present invention will be described with reference to the accompanying drawings in FIGS. The breaker 1 is provided with a first pole terminal device 3a and a second pole terminal device 3b at both ends of a case 2. The first pole terminal device 3a and the second pole terminal device 3b
Are displaced from each other in the insertion direction of the electric wires 4 and further displaced from each other in the vertical direction with respect to the insertion direction of the electric wires 4. Thus, the first pole terminal device 3a and the second
The pole terminal devices 3b can be arranged so as to overlap in the width direction of the case 2, and the width of the case 2 can be reduced. On the upper surface of the case 2, respective terminal devices 3a,
A driver insertion hole 6 for inserting a driver for turning the terminal screw 5 of 3b is formed, and a conductor insertion hole 7 for connecting a conductor to the terminal devices 3a and 3b is formed on an end surface of the case 2. In this embodiment, the terminal device uses a screw terminal. However, a terminal device without a screw may be used. Although both sides of the case are formed in the same shape, only the side of the case to which the electric wires are connected may be used, and there is no limitation on the side to which the conductive bar is connected. As described above, in a breaker provided with at least a two-pole terminal device of a case, each terminal device is shifted in the direction of insertion of the electric wire, and the terminal device is vertically moved with respect to the insertion direction of the electric wire. With such an arrangement, the width of the breaker can be reduced, and the distribution board can be downsized.
