Next, electrical equipment attached to the member 1 to be mounted
10 will be described. The electric device 10 includes a board 10a, a connector 10b mounted on the board 10a, and a terminal block 10c.
Consists of

Next, a procedure for mounting the electric device 10 on the mounting rail 20 using the above device will be described. First,
A mounting member 1 is formed by connecting four mounting plates 11 in series.
Specifically, the protrusion 11j of the mounting plate 11 is
11 into the hole 11k of the protrusion 11m, and
By inserting the 11 projecting pins 11p into the holes 11q of the adjacent mounting plate 11, four mounting plates 11 are connected in series to form the mounting member 1. In this state, the board 10a is slid along the grooves 11n of the four mounting plates 11 to
To the member 1 to be mounted.

Next, the mounting plate 11 constituting the mounting member 1
In the state where each of the one locking portions 11d is locked to the one projecting piece 20a of the mounting rail 20, the engaging portion 2c of the mounting member 2 is engaged with the engaged portion 11f of the two mounting plates 11 at both ends. Respectively. Specifically, when the attachment member 2 is slid so as to be held in the recess 11e of the attached plate 11 by gripping the operation portion 2e,
Most of the mounting member 2 is accommodated in the recess 11e of the mounting plate 11 such that the engaged portion 11f of the mounting plate 11 is sunk into the notch 2d of the mounting member 2. By doing so, the mounting member 2
The two substantially opposing pieces forming the engaging portion 2c of the
The elastic portion holds the angled portions of both opposed pieces constituting the engaged portion 11f of the engaging member 11f, and engages the engaging portion 2c of the mounting member 2.
The intermediate piece constituting the engaging plate 11 enters and engages with the opposing space of the opposing pieces constituting the engaged portion 11f of the attached plate 11. At this time, the other locking portion 2a of the mounting member 2 is locked to the other protruding piece 20b of the mounting rail 20, the mounting plate 11 is mounted on the mounting rail 20, and the electric device 10 is mounted on the mounting rail 20. Will be done.

Next, the end plate 3 is connected to the attached plates 11 at both ends. Specifically, the projecting portion 11j of the attached plate 11 is inserted into the hole 3f of the convex portion 3c of the end plate 3, and at the same time, the projecting portion of the attached plate 11 is
Insert the protruding portion 3b of the end plate 3 into the hole 11k of 11m, and simultaneously insert the protruding pin 11p of the mounting plate 11 into the hole 3e of the end plate 3, and simultaneously insert By inserting the protruding pins 3 d of the end plate 3, the attached member 1 including the four attached plates 11 is connected to the pair of end plates 3.

Next, the pins 4 are inserted into the through holes 3a of the pair of end plates 3.
Then, it is connected to the through hole 11h of the mounting plate 11 and screwed, and finally, the cover 5 is covered with the end plate 3 to complete the mounting operation.

Next, a modification of this embodiment will be described with reference to FIGS.
It will be described based on. 6 to 8, the mounting rail 20 is omitted. Further, members having substantially the same functions as those of the present embodiment are denoted by the same reference numerals, and only different points from the present embodiment will be described. In the modification, the longitudinal direction of the mounting rail 20 in the electric device 10 is shortened, and accordingly, the mounted member 1 includes three mounted plates 11,
The mounting member 2 is mounted on a central one of the mounting plates 11.

In such a mounting device for an electric device, the mounting rail can be set according to the size of the electric device 10 without preparing two types of mounting members corresponding to the size of the electric device 10. Plates 11 to be connected to each other along 10
By adjusting the number of the attached plates 11 of the attached member 11 made of from three to two, it is possible to attach the electric devices 20 having different sizes. In addition, in the mounted member 1, the one locking portion 11d locks the one protruding piece 20a of the mounting rail 20, and the other locking portion 2a of the mounting member 20 mounted on the mounted member 11 is mounted. By locking the other overhanging piece 20a of the rail 20, the rail 20 can be directly mounted on the mounting rail 20, so that the mounting workability can be improved.

The mounting plate 11, which is point-symmetrical with respect to the center point in plan view, is rotated by 180 ° so that even if the width direction, which is the short direction of the mounting rail 20, is reversed, one of the locking portions is engaged. 11d
Is locked to the other overhanging piece 20b of the mounting rail 20,
Since the mounting member 2 mounted on the mounting plate 11 is also locked to the one projecting piece 20a of the mounting rail 20, the electric device 10 is mounted on the mounting rail 20.
20 can be attached. Therefore, the mounting position of the mounting member 2 to be mounted on the mounting plate 11 can be selected on either side of the mounting rail 20 in the width direction according to the installation condition of the mounting rail 20. Can be.

In the present embodiment and its modifications, the mounting plate 11 has an outer peripheral edge symmetrical with respect to the center point in plan view, but, for example, the mounting rail 20 is installed in a wide place. In order to facilitate the work from both sides of the mounting rail 20 in the short direction, it is possible to rotate the mounting plate 11 by 180 ° to reverse the width direction which is the short direction of the mounting rail 20. If not, it is not necessary to adopt such a configuration, and in that case, the degree of freedom of design can be increased.

In this embodiment and its modifications, the mounting plate 11 is composed of four or three mounting plates 11.
The number is not limited to three or three.

In this embodiment and its modifications, the number of the attachment members 2 is two or one, but the number is not limited to two or one.

Further, in the present embodiment and its modifications, the electric device 10 includes the board 10a, the connector 10b and the terminal block 10c mounted on the board 10a, but is not limited thereto.

In this embodiment and its modifications, the mounting plates 11 are connected to each other by inserting the protrusions 11j into the holes 11k of the protruding portions 11m of the adjacent mounting plate 11, for example. However, the connecting means is not limited to this.

The assembling procedure is not limited to the above-described procedure. For example, the electric device 10 is mounted on the member 1 before the member 1 is mounted on the mounting rail 20. After the member 1 is mounted on the mounting rail 20, the electric device 10 may be mounted on the mounted member 1.

[0033]

According to the first aspect of the present invention, according to the size of the electric equipment, the members to be attached to each other along the mounting rail can be prepared without preparing the mounting members having various sizes corresponding to the size of the electric equipment. By adjusting the number of the attached plates of the attached members composed of a plurality of attached plates, even electric devices having different sizes can be attached. Moreover, in the mounted member, the one locking portion locks the one protruding piece of the mounting rail, and the other locking member of the mounting member mounted on the mounted member fixes the other protruding piece of the mounting rail. By locking, it can be directly mounted on the mounting rail, so that the mounting workability can be improved.

According to a second aspect of the present invention, in addition to the effect of the first aspect, the plate to be mounted, which is point-symmetric with respect to the center point in plan view, is rotated by 180 ° so that the short side of the mounting rail can be obtained. Even if the width direction is reversed, the one locking portion is locked to the other protruding piece of the mounting rail, and the mounting member mounted on the mounting plate is also locked to the one protruding piece of the mounting rail. Therefore, the electric device can be mounted on the mounting rail.
Therefore, the mounting position of the mounting member to be mounted on the mounting plate can be selected on either side in the width direction of the mounting rail according to the installation condition of the mounting rail, so that usability can be improved.
