Description

[Detailed description of the invention] [Technical field] This invention relates to a remote control type circuit breaker.

[Background technology]

In addition to the handle, remote-controlled circuit breakers have a built-in electromagnet that turns the main contacts on and off and resets the trip, and the electromagnet is energized by a remote control signal. Therefore, this circuit breaker requires an operating terminal in addition to the main circuit terminal. Therefore, it is conceivable to provide the main circuit terminals at both ends of the breaker body and the operation terminals at the sides. However, when the operation terminals protrude from the sides, the circuit breakers become larger in the width direction and occupy more space, so if a large number of remote control circuit breakers are installed side by side on a distribution board, etc. However, the disadvantage was that the distribution board became larger. There was also a device in which a groove was provided on the side of the circuit or disconnector so that the lead wire could be drawn out from the center of the groove (for example, Utility Model Application No. 120640/1983).
However, in order to facilitate the handling of the lead wires, it is necessary to provide a separate operating terminal, and the width of the shingle breaker main body becomes large in order to form the grooves, as in the conventional example. Furthermore, when a plurality of circuits or disconnectors are installed in parallel, the wiring of the lead wires becomes complicated, resulting in poor aesthetics and the disadvantages of occupying a large space.

[Purpose of invention]

Therefore, the purpose of this invention is to provide a remote control that does not require a large width, has reliable insulation between the main circuit terminal and the operation terminal, and allows for good and aesthetically pleasing control wire wiring for the operation terminal. The purpose of the present invention is to provide a type circuit breaker.

[Disclosure of invention]

This invention consists of a main circuit breaker body, main circuit terminals provided at both ends of the main circuit breaker body, and a terminal in the center of the main circuit breaker body above at least one of these main circuit terminals. An operation terminal provided in a stepped manner on the side, and a screw tightening terminal provided to cover the upper part of the main circuit terminal and detachably arranged near the lower side of the operation terminal. An insulating plate formed with an opening for the operation, and a control line extending integrally from the insulating plate on the side opposite to the operating terminal so as to protrude from the disconnector body and connected to the operating terminal. This device includes a guide gutter portion that guides the disconnector body in the width direction, and a lid that closes the guide gutter portion.

According to the configuration of this invention, the operation terminal is provided in a step-like manner above the main circuit terminal and closer to the center of the disconnector body, so the width of the disconnector does not increase as in the conventional case. Moreover, the operation terminal does not interfere with the connection of the main circuit terminal. Moreover, because the insulating plate was located above the main circuit terminal and near the bottom of the operation terminal, when the control wire connected to the operation terminal is pulled out in the same direction as the main circuit conductor connected to the main circuit terminal, The insulating plate serves as a guide for the control wires, and the control wires can be wired well without hanging down or approaching the main circuit terminals, and mutual insulation can be ensured. Furthermore, since the insulating plate is detachable, the structure of the breaker body can be simplified, and assembly and wiring can be made easier.
Since screw tightening openings are formed in the insulating plate, it is easy to connect and retighten the main circuit terminals after installing the insulating plate. Furthermore, since a guide gutter is provided on the insulating plate, the control wire of the operating terminal can be pulled out in the width direction of the disconnector body through the guide gutter while ensuring insulation from the main circuit terminal, compared to conventional examples. Since there is no need for a groove in the disconnector body, the width can be shortened, and the guide gutter extends beyond the disconnector body, making it easy to use when multiple circuit disconnectors are installed in parallel. Since the guide gutter section is lined up in a straight line in the width direction, the control lines of other circuits and disconnectors can also be guided by the guide gutter section, and all control lines can be aligned at the ends in the direction in which the circuits and disconnectors are lined up. In addition, by hiding the control lines with the lid, the control lines can be routed aesthetically and neatly.

Recesses 8 are formed in the cutter main body 1 at positions substantially on both sides of the terminal 2, and the guide gutter portions 6b are attached by locking the hooks 6c into the recesses 8 using resin elasticity. At this time, the insulating plate 5 is placed on the receiving stage 7 and detachably covers the upper part of the terminal 2.

Then, the lid 22 is hooked onto the hook 6c and is supported by the support plate 6d so as to cover the control line 21 astride the continuous guide gutter portion 6b.

With this configuration, the width and height of the remote control circuit and disconnector do not increase, so the size can be reduced, and the space occupied in the width direction does not increase, so the distribution board does not become large. The terminals 2 and 4 are isolated from each other by an insulating plate 5, and the opening 6a does not hinder the connection of the main circuit terminal 2.

[Effect of idea]

As described above, according to the remote control type circuit breaker of this invention, the operation terminal is provided in a stepped manner above the main circuit terminal near the center of the breaker body, which is different from the conventional one. Therefore, the width of the disconnector does not increase, and the operation terminal does not interfere with the connection of the main circuit terminal. Moreover, because the insulating plate was located above the main circuit terminal and near the bottom of the operation terminal, when the control wire connected to the operation terminal is pulled out in the same direction as the main circuit conductor connected to the main circuit terminal, The insulating plate serves as a guide for the control wires, and the control wires can be wired well without hanging down or approaching the main circuit terminals, and mutual insulation can be ensured. Furthermore, since the insulating plate is detachable, the structure of the breaker body can be simplified, and assembly and wiring can be made easier.
Since screw tightening openings are formed in the insulating plate, it is easy to connect and retighten the main circuit terminals after installing the insulating plate. Furthermore, since a guide gutter is provided on the insulating plate, the control wire of the operating terminal can be pulled out in the width direction of the disconnector body through the guide gutter while ensuring insulation from the main circuit terminal, compared to conventional examples. Since there is no need for a groove in the disconnector body, the width can be shortened, and the guide gutter extends beyond the disconnector body, making it easy to use when multiple circuit disconnectors are installed in parallel. Since the guide gutter section is lined up in a straight line in the width direction, the control lines of other circuits and disconnectors can also be guided by the guide gutter section, and all control lines can be aligned at the ends in the direction in which the circuits and disconnectors are lined up. In addition, by hiding the control lines with the lid, the control lines can be routed aesthetically and neatly.
