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 mounting structures of this type 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. The 451 device 2 is held on the rail 1 by pressing and holding edges 101 protruding from both sides of the rail.

[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 I! between the rail 1 and the pawl 4.5! J-friction differential coefficient member, for example, rail 1 is made of aluminum, claw 4.5
is made of polyacetal V14I18,
Coupled with the large variation in the plate thickness of the rail 1, it is difficult to expect a holding force in the longitudinal direction of the rail 1, and the equipment 2 easily slides on the rail 1 in the longitudinal direction of the rail 1. This has drawbacks such as the equipment 2 falling off the rail 1 and the equipment 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]

Electricity according to this invention 8! The rail mounting device for the device is used to mount an electrical device on a rail having a U-shaped cross section so as to sandwich it from both sides, and is made of a flexible elastic material such as rubber with holes with a coefficient of friction, and is used to connect the rail and the bottom of the electrical device. An anti-slip pad is disposed between the rails and is compressed by the rail and the bottom of the electrical equipment when the electrical equipment is installed on the rail, and is in pressure contact with both the rail and the bottom of the electrical equipment, and [? The part of the bottom surface that comes into contact with the anti-slip pad has an uneven surface.

[Effect]

In this invention, the anti-slip pad can be embedded into the irregularities on the bottom of the equipment to securely hold it, and the pad is interposed between the rail and the bottom of the electrical equipment, so that the electrical equipment does not wobble on the rail. It should be possible to prevent it from sliding.

〔Example〕

The following Figures 1, 2 and 3 show an embodiment of the present invention.
This will be explained based on the diagram. In the figure, 6 is an anti-slip pad made of a flexible elastic material with friction coefficient holes such as rubber, and its thickness T is larger than the depth L of the rail 1, and A large number of linear unevenness 7 is formed on the bottom surface of the storage groove 3. 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 placed between the rail 1 and the 81 device 2.
Insert. Thereafter, when the device 2 is pushed in the direction of arrow B, the movable claw 5 advances and retreats in the direction of arrow C to pass the other edge 101 of the rail 1, and as shown in FIG. The edges 101 on both sides of the rail 1 are pressed and clamped, and the device 2 is mounted on the rail 1. Here the third
In the illustrated installation state, the anti-slip pad 6 (yo-rail) and the device 2 are compressed, and the rail 1 and the device 2 are compressed.
Apply pressure to both. That is, frictional force is generated between the rail 1 and the six anti-slip pads and between the anti-slip pad 6 and the device 2, and this frictional force causes the device 2 to be firmly held on the rail 1 via the anti-slip pad 6. Become.

In addition, since a large number of streak-like unevenness 7 are provided on the bottom of the groove 3 of the electric 8N device 2, the contact area between the anti-slip pad 6 and the device 2 is increased, and the lateral slippage between the device 2 and the pad 6 is more securely prevented. +h
can be expected. Incidentally, the unevenness 7 provided on the 8N device 2 is not limited to a linear one, but may be any shape that provides a large contact area with the pad 6 when the pad is press-contacted.

〔Effect of the invention〕

According to this invention, the equipment 2 is connected to the rail 1 as in the conventional one.
If you slide on the top and fall off the rail 1, or if you fall off the rail 1,
A device 2 does not rattle. Furthermore, with conventional devices, it was impossible to install the rail 1 vertically because the device 2 would slide and fall due to gravity, but according to the present invention, the device 2 can be firmly placed on the rail 1 by the anti-slip pad 6. Since it is held, vertical installation of the rail 1 is also possible, and the flexibility of installation is dramatically expanded.

Furthermore, in the present invention, since the bottom surface of the device 2 is provided with a large number of unevenness, the rv# movement prevention pad does not shift laterally, and the workability is dramatically improved.
