Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch switching state display structure.

[0002]

[Prior Art]

 In general, a switch is provided with an opening / closing part made up of a fixed electrode and a movable electrode corresponding to the fixed electrode in the main body case, and the opening / closing part is operated by a switching handle provided outside the case. The mechanical part that drives the parts is operated. Whether the operation state is the closed state (“on”) or the open state (“off”) for the manual type, the automatic state (“ Whether it is "automatic") or a manual entry state ("manual entry") is displayed externally by making the display pointer provided on the switching handle correspond to the indication written on the case. .

[0003]

[Problems to be solved by the device]

 However, as the size of switchgear has become more compact in recent years, the size of the main unit case has been promoted, while there is space available for switchgear switching status display on the downsized case in terms of urban beautification. It is small and limited.

An object of the present invention is to provide a switching state display structure for a switch, which allows the display space to be kept as small as possible and allows the display state to be visually checked easily.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention adopts a dogleg-shaped switching operation handle for switching between "ON", "OFF" or "manual ON", and "automatic", which is provided on the switch case. It is fixed to the operation shaft that penetrates the switch body with a bent portion, and on the switch case surface, the above-mentioned "entry", "off" or "manual insertion", "manual insertion", in a substantially straight line sandwiching the operation shaft. A display section of `` automatic '' is provided, and a pair of display pointers indicating the respective operation states are projected on the switching operation handle in the anti-bending direction, and the switch case is provided with a display pointer different from the display pointers indicating the operation state. The gist is to install a shielding plate that covers the display pointer that points to the non-display part.

[0006]

[Action]

 According to the present invention configured as described above, when the switch is operated by the switching handle, one display pointer surely indicates the state in the vicinity of the operation axis according to the operation with a small space, and vice versa. The other display pointer that indicates the display state of is displayed at the time of display is hidden by the shield plate provided in the switch case. Therefore, the display section has a small space in the switch case and always exists as a display section that indicates only the corresponding state of the switch, so that the operator can easily confirm the switch state.

【Example】

 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, bushings 3 and 4 on the load side and the power supply side for each phase are hermetically inserted and attached to both side walls of a switch case 2 of a switch 1. Further, the switch case 2 has a built-in opening / closing part (not shown) composed of fixed electrodes, movable electrodes, etc., and a mechanism part (not shown) for driving the opening / closing part to open / close.

Further, a handle shaft 5 as an operating shaft connected to a mechanical portion is provided on the front surface of the switch case 2 in a protruding manner, and an end portion of the handle shaft 5 has a dogleg-shaped switching handle. 6 is rotatably fixed. Further, on the substantially straight line on the front side of the switch case 2 sandwiching the handle shaft 5, a display 7a indicating the closed state of the switch 1 is displayed on the left side with the handle shaft 5 as a center with the character "ON". Has been done. Further, on the right side, a display 7b showing the open state of the switch 1 is displayed by the character "OFF". The display 7a, 7b, the pointers 8a, 8b, which will be described later, and the shield plate form a display portion, which is arranged at the lowermost end portion of the switch.

As shown in FIGS. 3 and 4, a pair of finger needles 8 a and 8 b are attached to the outer edge of the intermediate bent portion of the switching handle 6. Further, substantially rectangular cover plates 9a and 9b for covering the pair of the displays 7a or 7b are attached to the upper end of the switching handle 6 near the middle bent portion. Further, mounting members 10a and 10b for mounting the switch 1 on a mounting bracket T fixed to a utility pole P are attached to the upper and lower ends of the switch case 2, and the switching members are mounted on both side surfaces of the lower mounting member 10b. A pair of stoppers 11a and 11b that prevent the handle 6 from rotating are provided.

The lower mounting member 10b is also used as a shielding plate so as to cover the entire surface of the hands 8a and 8b when the hands 8a and 8b are not displayed. Next, the operation of the switching state display structure of the switch 1 thus configured will be described.

When the switch 1 is manually closed, the switching handle 6 is rotated clockwise around the handle shaft 5. Then, the switch 1 is turned on, and the switching handle 6 is prevented from rotating by the stopper 11b. At this time, the pointer 8a of the switching handle 6 indicates the display 7a ("ON") in the left direction (in FIG. 3). Further, the other pointer 8b is covered with the mounting member 10b, and the observer can recognize only the presence of the pointer 8a as a display pointer. Further, the cover plate 9b of the switching handle 6 covers the display 7b ("OFF") indicating the open state.

When the switch 1 is manually opened, the switching handle 6 is rotated counterclockwise around the handle shaft 5 from the closed state. Then, the switch 1 is opened and the switching handle 6 is prevented from rotating by the stopper 11a. At this time, at this time, the pointer 8b of the switching handle 6 indicates the display 7b ("OFF") in the right direction (in FIG. 4). Further, the other pointer 8a is covered with the mounting member 10b, and the observer can recognize only the presence of the pointer 8b as a display pointer. Further, the cover plate 9a of the switching handle 6 covers the display 7a ("ON") indicating the closing state.

As described above, in the switching state display structure of the switch according to the present embodiment, one display pointer surely indicates the state in the vicinity of the operation axis in accordance with the operation, and the opposite display state is displayed. The other display pointer pointed at the time is hidden by the mounting member 10b that also serves as the shield plate provided in the switch case, so that the display space of the displays 7a and 7b can be reduced and the display 7a and 7b are Since it always exists as a display section that indicates only the relevant display of the switch, the viewer can easily check the open / closed state.

Further, in the switching handle 6 of the present embodiment, the switching handle 6 is provided with cover plates 9a and 9b so as to cover the display 7a or the display 7b showing the state opposite to the closed state or the open state. By doing so, it is possible to easily confirm the open / closed state.

The present invention is not limited to the above-described embodiment, and the following may be made without departing from the spirit of the present invention. (1) In the above embodiment, the manual switch is used, but an automatic switch may be used. (2) In the above embodiment, the cover plates 9a and 9b are separately provided on the switching handle 6, but instead of this, each cover plate may be provided in an integral shape such as a fan shape.
