Abstract

(57) [Summary] [Purpose] To provide a breaker with a terminal block that facilitates the work of connecting conductors even when the terminal size of the breaker is different from that of the distribution board. [Structure] A terminal block 4 is connected to a terminal portion of a breaker 1, and the two are electrically connected by a breaker connecting bar 9 to form a breaker with a terminal block. By changing the pitch, height, etc. of the primary side and the secondary side of the terminal block 4, it becomes possible to easily connect the conductors without performing special processing on the conductors as in the conventional case.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a breaker with a terminal block, which is used by being incorporated inside a distribution board or the like.

[0002]

[Prior art]

 A large number of breakers are installed inside the distribution board via a terminal block, but there are various breakers with different capacities, and the size of the terminal part varies depending on the capacities. The terminal pitch and height of the stand may not match the terminal pitch and height of the breaker terminal. Therefore, in such a case, there has been a problem that the conductor for connecting the two needs to be processed such as being curved or stepped, which requires a lot of time and effort for connecting the conductors.

[0003]

[Problems to be solved by the device]

 The present invention has been completed in order to solve the above-mentioned conventional problems and provide a breaker with a terminal block that facilitates the work of connecting conductors even when the terminal size of the breaker is different. It is a thing.

[0004]

[Means for Solving the Problems]

 A first invention made in order to solve the above-mentioned problem is a breaker with a terminal block in which a terminal block is connected to the terminal part of the breaker and the two are connected by a breaker connecting bar. It is characterized in that a terminal cover that reaches the terminal of the breaker is attached. A second invention is a breaker with a terminal block in which a terminal block is connected to the breaker terminal part and both are connected by a breaker connecting bar, and this terminal block is located on the side facing the breaker terminal part. The feature is that the pitch and the pitch on the opposite side are different. A third invention is a breaker with a terminal block, in which a terminal block is connected to a terminal part of a breaker and the two are connected by a breaker connecting bar, and a pole wall of the terminal part of the breaker and a pole of the terminal block. The feature of the present invention is that the end face of the wall and the end face are directly connected by the ridge and the groove.

【Example】

 Each device will be described in more detail below with reference to the illustrated embodiments. FIG. 1 shows an embodiment of the first invention, in which 1 is a breaker, 2 is a terminal portion on the primary side thereof, and 3 is a terminal portion on the secondary side thereof. Reference numeral 4 denotes a terminal block, in which a ridge 6 formed on the end face of the interelectrode wall 5 is fitted into a groove 8 formed on the end face of the interelectrode wall 7 of the terminal part 3 on the secondary side of the breaker 1. By doing so, the terminal block 4 and the breaker 1 are connected to each other.

Further, the secondary side terminal portion 3 of the breaker 1 and the terminal block 4 are electrically connected by screwing breaker connecting bars 9 for three poles. Further, in the first invention, the terminal cover 10 reaching the terminal portion 3 of the breaker 1 is attached to the upper surface of the terminal block 4, and the two are integrated in appearance.

The breaker with a terminal block according to the first aspect of the invention configured as described above is one in which the terminal block 4 and the breaker 1 are integrated structurally, electrically, and externally. By adjusting the height, width, etc. in the section of 4, the breaker 1 of various capacities can be connected to other members via the terminal block 4 integrated with the breaker 1. For this reason, there is no need to process the conductor as in the conventional case, the connection work of the conductor is easy, and the appearance is neat.

FIG. 2 shows an embodiment of the second invention, in which the pitch of the terminal block 4 on the side facing the terminal portion 2 of the breaker 1 and the pitch on the opposite side are different. If the terminal block 4 configured in this way is attached to the terminal part 2 or the terminal part 3 of the breaker 1, even if a wire thicker than the maximum connection wire is attached to the breaker 1, a primary receiving terminal block one rank larger is used. There is no need, and connection work can be done easily.

FIG. 3 shows an embodiment of the third invention, in which a terminal block 4 is connected to the terminal section 2 on the primary side of the breaker 1. A groove 8 is formed on the interelectrode wall 7 of the terminal portion 2, and a ridge 6 is formed on the end surface of the interelectrode wall 5 of the terminal block 4. The two are directly coupled by utilizing the groove 8 and the ridge 6.

Therefore, conventionally, in order to prevent a short circuit between the connecting conductors due to arc gas at the time of a short circuit, it is necessary to attach an inter-electrode barrier 11 as shown in FIG. 1 between the breaker 1 and the terminal block 4. On the other hand, in the present invention, since the inter-electrode wall 7 of the terminal portion 2 and the inter-electrode wall 5 of the terminal block 4 are directly coupled, it is not necessary to attach the inter-electrode barrier 11 as in the conventional case, Insulation between the poles can be easily secured.

[0011]

[Effect of device]

 As described above, according to the present invention, by integrating the breaker and the terminal block, the terminal pitch and height of the breaker terminal can be freely adjusted, and a step is formed on the connection conductor as in the conventional case. It is not necessary to perform processing such as. Therefore, the conductor connecting operation can be easily performed. Also, by attaching a terminal cover as in the first invention, both can be integrated in appearance, and according to the third invention, it is not necessary to attach the inter-electrode barrier as in the conventional case. Therefore, the present invention has a great practical value as a breaker with a terminal block that solves the conventional problems.
