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.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.

[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 device provides an operating terminal in the upper part of at least one of the main circuit terminals, and provides an insulating plate near the lower part of the operating terminal above the main circuit terminal so as to cover the main circuit terminal. An opening for tightening the screw for the main circuit terminal is formed in the insulating plate, and a guide gutter is integrally extended on the opposite side of the insulating plate from the operating terminal to route the control line of the operating terminal in the width direction of the breaker. It is characterized in that the guide gutter portion is closed with a lid integrally formed with a thin hinge and the control line is hidden.

Since the operating terminal is provided in the upper part of the main circuit terminal and not on the side of the circuit or disconnector, the width and height of the disconnector do not increase, and the terminals can be insulated from each other by the insulating plate. Furthermore, since the insulating plate has openings for tightening screws, it does not interfere with the connection of the main circuit terminals, and since the insulating plate is located above the main circuit terminals and below the operating terminals, the wiring to the operating terminals is not hindered. It serves as a guide when pulling out the control line in the same direction as the main circuit conductor connected to the main circuit terminal, and prevents the control line from sagging and approaching the main circuit terminal.
Moreover, since the guide gutter portion is provided on the insulating plate, the wiring of the control line can be aesthetically arranged when a large number of shields and disconnectors are installed in parallel, and the aesthetic appearance is further improved by hiding the control line with the lid. Furthermore, since the lid is integrally formed, there is no risk of losing it and it is easy to handle.In addition, when installing many shield disconnectors in parallel and guiding the control line to the adjacent guide gutter section, the control line can be used sequentially. Wiring work is easy because you can store it in the guide gutter while opening and closing the lid.

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 main circuit terminal 2 on the power supply side. An electromagnet operation terminal 5 installed in the upper part of the electromagnet is an insulating plate made of an insulating synthetic resin such as vinyl chloride resin. This insulating plate 5 has a screw tightening opening 6a and is integrally provided with a guide gutter portion 6b at one end, and further has a guide gutter portion 6b.
A lid 6d is integrally formed on the edge of the guide gutter portion 6b with a thin hinge 6c, and a locking hook 6 is provided on the opposite edge of the guide gutter portion 6b.
6e is erected, and a pair of mounting hooks 6f are protruded from the insulating plate 5 side at both ends of the guide gutter portion 6b.

A receiving step 7 is formed in the disconnector body 1 at the upper part of the power supply side main circuit terminal 2 and below the operation terminal 4, and a recess is formed in the disconnector body 1 at the position on almost both sides of the terminal 2. 8 is formed, and by locking the hook 6f in the recess 8 using resin elasticity, the guide gutter portion 6b
is installed. At this time, the insulating plate 5 is placed on the receiving stage 7 and covers the upper part of the terminal 2.

9 is a handle for turning on, off and resetting the main contact; 10 is a 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
The screws 2 are tightened and loosened by passing a jig such as a screwdriver 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 19 is the circuit of this invention used for branching. 20 is the front lid,
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. In this case, the guide gutter part 6
When the control wires 21 are stored in the wires b, if the lid 6d is closed while sequentially storing the control wires 21, the wires will be easily stored and the wiring work will be made more efficient. and lid 6d
The control line 21 is hidden by.

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. In addition, since the control wire 15 connected to the operation terminal 4 is guided by the insulating plate 5 and guided to the guide gutter portion 6b, insulation from the main circuit conductor 12 can be ensured, and the control wire 15 is routed aesthetically. Since it is hidden, the beauty is further improved. Furthermore, since the lid 6d is integrally hinged, there is no risk of it being lost, and wiring work becomes easier.

[Effect of idea]

As described above, according to the remote control type circuit breaker of this invention, the main circuit breaker body can be made smaller, insulation between the operation terminal and the main circuit terminal can be ensured, and moreover, the main circuit terminal can be Control lines can be wired safely and aesthetically without interfering with wiring connections, and there is no need to lose the cover that hides the control lines, making wiring work easier when many circuits or disconnectors are installed in parallel. There is an effect.
