Description

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

[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.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 circuits and disconnectors become larger in the width direction and occupy more space. The disadvantage was that the distribution board became larger. There were also devices 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).
In order to facilitate the handling of the lead wires, it is necessary to provide a separate operating terminal, and in order to form the grooves, the width of the breaker main body becomes large, as in the conventional example. Also, if multiple circuits or disconnectors are installed in parallel,
Not only does the wiring of the lead wires become complicated and the aesthetic appearance deteriorates, but it also has the disadvantage of taking up a large amount of 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. It is equipped with a guide gutter portion that guides the disconnector body in the width direction.

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 removable, the structure of the breaker body can be simplified, and assembly and wiring can be made easier.Also, since the insulating plate has openings for tightening screws, the insulating plate can be attached easily. You can easily connect and retighten the main circuit terminals. 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 side by side. 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. Therefore, the control lines can be routed in a more aesthetically pleasing manner.

An embodiment of this invention is shown in FIGS. 1 and 2. In other words, 1 is the remote control type circuit breaker body, 2, 3 is the main circuit terminal provided at both ends of the breaker body 1, and 4 is the power supply side circuit terminal 2. At the top, an electromagnet operation terminal is installed in a stepped manner near the center of the disconnector body 1, and 5 is an insulating plate made of an insulating synthetic resin such as vinyl chloride resin. This insulating plate 5 has an opening 6a for screw tightening and is integrally provided with a guide gutter portion 6b at one end. A receiving stage 7 is formed on the disconnector body 1 at the upper part of the power supply side main circuit terminal 2 and the lower part of the operating terminal 4, and a fixing protrusion 8 is integrally formed on the upper part of the receiving stage 7. Using the elasticity of the terminal 5, the insulating plate 5 is secured to the receiving stage 7 by climbing over the projection 8, and detachably covers the upper part of the terminal 2.
Further, at this time, the guide gutter portion 6b protrudes from the end of the cutter main body 1, and its axial direction is directed in the width direction of the cutter main body 1.

9 is a handle for turning on, off and resetting the main contact; 10 is a manual trip button; 11 is a mounting groove on the cutter body 1; 12 is a main circuit conductor connected to the main circuit terminal 2 on the power supply side; This main circuit conductor 1
Tightening and loosening of screws 2 are performed by passing a jig such as a delivery bar through the opening 6a. 13 is a main circuit conductor wire connected to the load side main circuit terminal 3, and 14 is an insulating lid. Note that mechanical parts such as the opening/closing mechanism and the tripping mechanism are well known, so illustration and description thereof will be omitted.

Figures 3 to 5 show the case where this remote control type circuit breaker is applied to a distribution panel. In other words, 15 is the outer case of the distribution board, 16 is the door, 17 is the main circuit/disconnector, 18 is the normal branch circuit/disconnector, and 16 is the circuit of this invention used for branching. The disconnector 20 is a front cover, and the front cover 20 and the operation terminal 4 are insulated by the insulating cover 14. As shown in FIG. 5, the control wire 21 connected to the operating terminal 4 is guided by the insulating plate 5 and led to the guide gutter section 6b, and the control wire runs inside the guide gutter section 6b of the adjacent continuous circuit and disconnector. 21 and wired together.

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. Also, the control line 1 connected to the operation terminal 4
5 is guided by the insulating plate 5, and the guide gutter portion 6b
Since insulation from the main circuit conductor 12 can be ensured, the control line 15 can be routed aesthetically.

[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 removable, the structure of the breaker body can be simplified, and assembly and wiring can be made easier.Also, since the insulating plate has openings for tightening screws, the insulating plate can be attached easily. You can easily connect and retighten the main circuit terminals. 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 side by side. 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. Therefore, the control lines can be routed more aesthetically.
