Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is a collective terminal at the rear of a collective display device in which a plurality of single devices such as indicator lights or pushbutton switches are vertically and horizontally arranged and fixed in a mounting frame. The present invention relates to a mounting device that mounts a protective cover on a pedestal to prevent an electric shock from being touched by a hand and a short circuit caused by contact of an object.

[Conventional technology]

200V or 220V is used as a commercial power source in Europe and America, and 200V may be used in the future in Japan.

Therefore, it is necessary to provide a protective device to prevent electric shock in an electric device including a terminal block portion where a terminal screw, which is a conductor connecting portion, is exposed.

For example, when a push button switch or the like is used alone, the individual terminal block portions of the single device mounted on the panel are covered with a protective cover, and the indicator lamp and push button switch as shown in FIG. In the case of the collective display device 1 in which a plurality of single devices 2 are arranged in a grid in a mounting frame 3 having a rectangular shape and a flange portion 3c on one side, the rear portion (on the right side of the drawing)
Since a plurality of terminal block portions 2a are assembled on the inner surface of the panel 5 on which the collective display device 1 is mounted,
The four studs 7 are provided in a cantilevered manner by welding 8 at positions corresponding to the size, and the collective display device 1 is inserted from the front surface of the panel into the mounting hole 5a of the panel 5, and then the mounting device 4 (Shown in FIG. 6) is mounted on the mounting frame 3, and locking pieces 4b and 4c formed by projecting on one side surface of the base 4a by a press are locking holes 3a formed on the side wall 3d of the mounting frame 3. , 3b, respectively, and both ends of the base 4a are bent to the opposite sides with respect to the locking pieces 4b, 4c. By tightening the
End portion 41a contacts the rear surface of the panel 5 to press the panel 5, and the locking pieces 4b and 4c contact the edge portions of the locking holes 3a and 3b to move the mounting frame 3 rearward (to the right in the drawing). And the panel 5 is clamped by the flange portion 3c of the mounting frame 3 and the tightening screw 41, and the mounting device 4 is provided at a predetermined position of the mounting frame 3, so that the collective display device 1 It will be fixed and attached to the panel 5.

Then, at the end of each stat 7 provided on the panel 5,
A protective cover 6 made of synthetic resin having a size and size capable of concealing all the terminal block portions 2a is fixedly supported by a mounting screw 61.

[Problems to be solved by the device]

However, in the above-mentioned mounting means, the mounting position of each stud 7 is designed based on the area of the collective display device 1 to be mounted, so that the processing cost of the mounting panel 5 is high including the cost of creating the design drawing, and Since the stud 7 is fixed by welding 8, its removal is not easy, so
Even if the specification of the collective display device 1 is changed to increase the area, there is a problem in that it cannot be dealt with.

The present invention has been made in view of such conventional problems, and can easily and inexpensively process a panel regardless of the size of the shape of the collective display device, and the specifications of the collective display device. It is a technical object to provide an attachment device that can easily attach the protective cover even when the device is changed.

[Means for Solving the Problems]

As a technical means for achieving the above-mentioned object, the present invention has a mounting device for mounting a protective cover as follows.

That is, a collective display device in which a plurality of single devices such as an indicator lamp or a push button switch having a terminal block portion at the rear is arranged vertically and horizontally in a mounting frame is inserted from the front of the panel into a mounting hole formed in the panel. Then, the locking portion formed on one side surface of the base is engaged with the locking portion formed on the mounting frame, and is screwed into the mounting piece formed on the other side surface of the base. In a mounting device for fixing the collective display device to the panel by clamping the tightening screw, and holding the panel with the flange portion formed on one side of the mounting frame and the tightening screw, An extension piece is formed at one end of the base so as to project from the terminal block portion of the single device, and an attachment portion for attaching an electrically insulating protective cover for preventing electric shock is formed at an end of the extension piece. Is configured.

[Action]

An extension piece is formed at one end of the base of the attachment device that attaches the collective display device to the panel, and an attachment portion is formed at the end of this extension piece, and protection is performed at this attachment portion. Since the cover is fixedly supported, even if the specifications of the collective display device are changed, the protective cover can be mounted simply by arranging the mounting device at a predetermined place, and the mounting holes formed on the panel are not connected to the collective display device. Since it only has to be formed into a size and shape that fits in the area, and it is not necessary to consider the disposition of the stat, it can be processed at low cost.
