Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for electrical equipment using a T')IN 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 equipment 2)
A fixed pawl 4 is provided on one side of the WN2, 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 equipment 2 is placed on the rail 1 by pressing and holding the edges 101 protruding from both sides of the rail 1.
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 pawl 4.5 is made of polyacetal resin. Due to the fact that the rail 1 is made of 100% 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 sliding on the rail 1.

This invention was made to solve the problems mentioned in 1-:
After installing the electrical equipment on one rail, the electrical equipment is prevented from sliding in the longitudinal direction of the rail.

[Means for solving problems]

The rail mounting device for electrical equipment according to the present invention has a cross section of
”-shaped rails from both sides J: Uniden fi at
1! ? When the electrical equipment is mounted on the rail, a flexible elastic material with a high friction coefficient such as rubber, It is equipped with an anti-slip pad that is compressed by J' on the bottom of the electric machine and comes into pressure contact with both the rail and the bottom of the electrical equipment, and the bottom of the rail groove that the bracket's anti-slip pad comes into contact with is uneven. .

[Function] In the invention of B, the anti-slip pad is firmly connected by the uneven insertion A in the bottom of the groove of the rail, and the pad is interposed between the rail and the bottom of the electrical equipment, so that the electrical equipment can be mounted on the rail. This prevents 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, 6 is an anti-slip pad made of a flexible elastic material with a high coefficient of friction, such as rubber, whose thickness T is equal to the groove depth t of the rail 1.
Furthermore, streak-like unevenness 102 is provided on the bottom surface of the groove of the rail 1. 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 explained. 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 1-knoll 1 and the equipment 2.
Insert. 17, 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, passing the other edge 101 of the rail 1, and as shown in FIG.
The edges 10 on both sides of the rail 1 are pressed and clamped, and the equipment 2 is mounted on the L--1. Here, in the installed state shown in the third figure, the anti-slip pad 6
1 is compressed between the lever 1 and the equipment 2, and presses against both the lever 1 and the machine N2. In other words, frictional force is generated between the rail 1 and the anti-slip pad 6, and between the anti-slip pad 6 and the equipment 2, respectively.
is firmly held on the rail 1 via the anti-slip 11 pad 6.

By the way, when the above-mentioned anti-slip pad 6 is installed on the rail 1, the anti-slip pad is wedged into the unevenness 102 provided at the bottom of the groove of the rail 1, and the contact area between the two becomes large, causing a gap between the rail 1 and the pad 6. We can expect more reliable prevention of lateral slippage.

Note that the unevenness 102 provided on the bottom surface of the rail 1 is shown in Figure 1 (b).
The one shown in (c) may also be used.

〔Effect of the invention〕

According to this invention, the equipment 2 is connected to the rail 1 as in the conventional one.
There is no possibility that the equipment 2 will fall off the rail 1 or rattle on the rail 1 when sliding on the rail 1. Further, in the conventional system, it was impossible to install the rail 1 vertically because the equipment 2 would slide and fall due to gravity, but according to the present invention, the equipment 2 is placed on the rail 1 by the anti-slip pad 6. -1-
Since the rail 1 is firmly held, it is possible to install the rail 1 vertically, and the flexibility of installation is dramatically expanded.

Furthermore, in the present invention, since the anti-slip pad is provided with a large number of irregularities on its contact surface with the rail, there is an effect that the engagement between the two becomes more reliable.
