Abstract

PURPOSE:To equip an electric apparatus with a movable claw on a mounting plate without being encumbered by said movable claw, by connecting the tip of the holding arm equipped in the movable claw with the bottom of the apparatus at a certain angle and forming two connecting parts at right angles to a groove. CONSTITUTION:Pushing a movable claw 6 in the direction of a groove 4 with hands disengages a holding arm 8 from a first projection 9a to move said movable claw 6 in the direction of said groove 4 and connect the holding arm 8 with a second projection 9b. Thus the movable claw 6 is completely inserted into an electric apparatus 3 to enable said device to be equipped on a mounting plate 2. This enables the installation of the apparatus 3 with the movable claw on not only a DIN rail but also the mounting plate without removing said movable claw 6. Therefore, equipping the apparatus on the mounting plate requires no space for storing the movable claw to prevent such accident as the loss of the movable claw.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides an electric Wt having a DIN rail mounting structure.
The present invention relates to a device for attaching a device.

[Conventional technology]

Conventionally, as this type of mounting structure, those shown in FIGS. 4 to 11 have been proposed. First, in Fig. 4, 1 is an approximately υ-shaped D having edges 11 on both sides and mounting holes 12 at the bottom.
This is an IN rail, and in FIG. 5, 2 is a mounting plate having a fixed claw 211 on one side and an elastic claw 22 on the other side. In FIGS. 6 and 7, 3 is an electrical device mounted on the DIN rail 1 and mounting plate 2, and 4! [3 has a groove 4 having a width comparable to that of the rail 1 on the back side, a fixed claw 5 is provided on one side of this groove 4, and a movable claw 6 that moves forward and backward in a direction perpendicular to the groove 4 is provided on the other side. It is being In addition, movable claw 6
is provided with a holding arm 8, and when the movable claw 6 is inserted into the bottom of the device 3 from the direction of the groove 4, the holding arm 8 elastically deforms over an engaging protrusion 9 formed on the bottom of the device. As shown in FIG. 7, all of the screws are engaged with this for proper attachment.

In the above-mentioned device, when installing the equipment 3 on the rail 1, as shown in FIGS. 8 and 9, the edge 1 of the rail 1
is fitted into a fixed claw 5 and a movable claw 6, and the edges are pressed and held so that the equipment 3 is held on the rail 1.

In addition, in order to enable the device 3 to be mounted in a different manner from the above, for example, recesses 7 are provided on the upper and lower sides of the device 3, and as shown in FIGS. The device 3 is also held on the mounting plate 2 by fitting the fixing claws 21 and elastic claws 22 of the mounting plate 2 and pressing and holding the recessed portions. However, when trying to hold the device 3 having the movable claw 6 on the mounting plate 2, the movable claw 6 of the device 3
It is necessary to remove the movable claw 6 because it protrudes and becomes a hindrance and cannot be installed.

Therefore, when the movable claw 6 is strongly pushed in the direction of the groove 4, the holding arm 8 and the projection 9 are disengaged, and the movable claw 6 can be removed from the device 3.

[Problem to be solved by the invention]

However, in the case of the conventional structure as described above, after the movable claw 6 is removed from the device 3, it is necessary to store the movable claw 6 in a different location from the device 3. At this time, it is necessary to remember the storage location. , or because it is necessary to record it,
Handling of the movable claw 6 was a problem.

This invention was made to solve the above-mentioned problems, and when installing equipment using a mounting plate, the movable claw is moved to a position where it does not interfere with the installation, and the movable claw is fixed to the equipment at this position. The purpose is to provide electrical equipment that can be stored.

[Means to solve the problem]

In the mounting device according to the present invention, the tip of the holding arm provided on the movable claw engages with the bottom surface of the device at an angle, and the engaging portions are arranged at two locations in a direction perpendicular to the groove.

[Effect]

In the electrical equipment of this invention, there are two engagement positions between the holding arm of the movable claw and the equipment side inclined engagement part, one of which is a position where the movable claw is used when installing the equipment on the DIN rail. and the other is a position where the movable claw does not get in the way when the device is attached to the mounting plate.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, 3 to 8 indicate the same parts as the conventional ones, but the engaging protrusion 9 is connected to the groove 4 of the device 3.
They are provided at two locations 9a and 9b at a predetermined interval in the direction perpendicular to the .

In the above device, by manually pushing the movable claw 6 in the direction of the groove 4, the holding arm 8 and the first protrusion 9a are disengaged, and the movable claw 6 can be moved in the direction of the groove 4. .

Then, the holding arm 8 engages with the second protrusion 9b, resulting in the state shown in FIG. It becomes possible to install the .

FIG. 3 is a sectional view of a portion of a movable claw 6 showing another embodiment of the present invention, in which 10a and 10b are provided on the device 3 at a place where the holding arm 8 and the device 3 are close to each other, and the tip of the holding arm 8 is This is a recess into which the movable claw 6 is fitted, and in this case as well, the movable claw 6 can be locked at two locations by manually pushing the movable claw 6 in the direction of the groove 4.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to attach the movable claw to the DIN rail as well as to the mounting plate while it is attached to the equipment without removing it from the equipment. There is no need to consider where to store the nails, and there is no risk of them being lost.
