Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for electrical equipment using a DIN rail.

[Conventional technology]

Conventional examples of this type and mounting structure are shown in Figures 4, 5, and 6.
As shown in the figure, a groove 3 for housing the rail 1 on the back side of the device 2
A fixed pawl 4 is provided on one side of the groove 3, and a movable pawl 5 that moves forward and backward in a direction perpendicular to the groove 3 via an elastic arm 51 is provided on the other side. 8112 on the rail 1 by pressing and holding the edges 101 protruding on both sides of the
is maintained.

[Problem that the invention seeks to solve]

However, in this conventional device, both the rail 1 and the pawl 4.5 are rigid bodies, and the rail 1 and the pawl 4.5 are made of a material with a small coefficient of friction, for example, the rail 1 is made of aluminum, and the pawls 4 and 5 are made of polyacetal resin. Due to the fact that the rail 1 is made of aluminum and the thickness of the rail 1 varies widely, it is difficult to expect that the holding force in the longitudinal direction of the rail 1 will be particularly strong. It has drawbacks such as the device 2 easily sliding and falling off the rail 1, and the device 2 rattling on the rail 1.

This invention was made to solve the above-mentioned problems, and is designed to prevent the electrical equipment from sliding in the longitudinal direction of the rail after it is mounted on the rail.

[Means for solving problems]

The rail mounting device for electrical equipment according to the present invention has a cross section of U
In a device where an electric EA device is attached to the rail so as to sandwich the rail from both sides, it is made of rubber or other material. [It is made of a flexible elastic material with a large coefficient, and is arranged between the rail and the bottom of the electrical equipment, and when the electrical equipment is installed on the rail, it is compressed by the rail and the bottom of the electrical equipment, and the rail and the bottom of the electrical equipment are compressed. The anti-slip pad is provided with an anti-slip pad that comes into pressure contact with both the anti-slip pad and the anti-slip pad is formed into a columnar shape with a substantially regular polygonal cross section.

[Function] In this invention, the anti-slip pad can be easily inserted into the groove without directionality, and since the pad is interposed between the rail and the bottom of the electrical equipment, the electric wIt device can be easily inserted on the rail. It should be able to prevent it from rattling or sliding.

〔Example〕

An embodiment of the present invention will be explained below based on FIG. 1(A), FIG. 2, and FIG. 3. In the figure, 6B' is an anti-slip pad made of a flexible elastic material with a high coefficient of friction, such as rubber, in the shape of a prism with a square cross section. This is set to be larger than t. The rest of the configuration is the same as the conventional one, so the explanation will be omitted.

Next, the manner in which the electrical equipment 2 is attached to the rail 1 using the anti-slip pad 6 will be described. As shown in FIG. 2, the fixing claw 4 is hooked onto one edge 101 of the rail 1 in the direction of arrow A, and then the anti-slip pad 6 is inserted between the rail 1 and the equipment 2. After that, when device 2 is pushed in the direction of arrow B,
The movable pawl 5 moves back and forth in the direction of arrow C to touch the other edge 1 of the rail 1.
01, the edges 101 on both sides of the rail 1 are pressed and clamped by the fixed pawl 4 and the movable pawl 5 as shown in FIG. Here the third
In the illustrated installation state, the anti-slip pad 6 is compressed by the rail 1 and the equipment 2 and is in pressure contact with both the rail 1 and the equipment 2. That is, it must be firmly held between the rail 1, the six anti-slip pads, and the anti-slip pad 6 and the machine 1.

When installing the above-mentioned anti-slip pad 6 onto the rail 1, since the anti-slip pad is a prism with a square cross section, there is no need to be particularly conscious of the mounting direction when selecting the anti-slip pad.

Incidentally, in the case of a rectangular cross-section as shown in Figure 7, it will not be possible to install it in the orientation shown in Figure 7 (A), and if it is installed in the direction shown in Figure 7 (B), the amount of compression will be too large. This may cause problems such as the pressure welding force being excessive and deforming the device 2.

Note that the anti-slip pad 6 is not limited to a square cross section, but may also be configured to have a regular polygonal shape as shown in FIGS. has the same effect.

〔Effect of the invention〕

According to the invention of Otsu, the 8112 does not slide on the rail 1 and fall off the rail 1, and the equipment 2 does not rattle on the rail 1, unlike the conventional one. Furthermore, with the conventional device, it was impossible to install the rail 1 vertically because the device 2 would move and fall due to gravity, but according to the present invention, the device 2 can be placed on the rail 1 by the anti-slip pad 6.
