接して設置されていた。2. Description of the Related Art A circuit breaker for a primary feed that branches and wirings without passing through a main breaker secures an emergency power source because power transmission is not interrupted even when the main breaker operates to cut off the circuit. It is used as a circuit. Conventionally, as the primary feed open circuit breaker, a commonly used small circuit breaker for branching is used, and as shown in a plan view inside the home distribution board of FIG. It was installed adjacent to the circuit breaker 32 connected to the secondary side of the main breaker 31.

2 is not connected to a charged portion such as the main bar 33 disposed in the distribution board, so that the connecting charged portion such as a branch bar extending from the main bar 33 is cut off. Was doing. And since the processing of this charged part can be performed only in a limited place such as the end of the main bar 33, the number of primary feed circuit breakers to be installed is limited.

There has been proposed a primary feed circuit breaker in which a concave portion 34 for accommodating a charged portion is provided on an upper surface or a lower surface of a casing at a charging portion contact position such as a branch bar on the board side.
In this way, by raising the connection terminal and forming it apart from the upper and lower ends of the casing, the connection terminal is arranged before the charging section of the distribution board when installed in the distribution board, and Since the primary feed wiring can be connected at a position distant from the terminal, the connection work is facilitated, and the provision of the storage section for the charging section eliminates the need to cut the branch bar or the like.

制約が厳しくなる。However, in order to form the primary feed circuit breaker of FIG. 5 with the conventional small circuit breaker size, the casing must be divided at least into three parts due to the assembly of parts. I had to. In this case, it is divided into three in the left-right direction as shown by the diagonal lines in FIG. 7, divided into three in the vertical direction, or divided into three parts in the center and left and right as shown by the diagonal lines in FIG. . Therefore, the number of parts is increased, the assembly cost and the management cost are also high, and the fitting surface of the casing increases, so that attention must be paid to gap management. FIG. 7
8A and 8B are bottom views of the circuit breaker, FIG. 8A is a side view of the circuit breaker, and FIG. As shown in the side view of FIG. 6, if the fixed contact 38 on the primary side and the terminal seat 39 are bent in opposite directions and formed at both ends of a primary-side conductor 40 formed in a crank shape, respectively, the casing becomes Although it is possible to cope with it only by dividing into two parts, it is difficult to secure an installation space when arranging components such as the movable contact 41 and the opening / closing mechanism (not shown). It is difficult to incorporate the circuit breaker into the circuit breaker size, and the space inside the circuit breaker is narrow, so that the dimensional restrictions on the components are severe.
