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 5, 6, and 7.
As shown in the figure, a groove 3 in which the rail 1 is housed is formed on the back surface of the M& A movable claw 5 is provided, and both the fixed claw 4 and the movable claw 5 press and hold the li 101 protruding from both sides of the rail 1, so that the equipment 2 is held on the rail 1.

[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 4.5r are made of a member with a small friction coefficient, for example, the rail 1 is made of aluminum, and the pawl 4.5 is made of aluminum.
is polyacetal all! 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. Fifth
It may easily slide in the direction of the target and fall off the rail 1,
It has drawbacks such as the machine vs2 shaking 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 Go! In this device, an electric device is attached to the rail so as to sandwich the rail from both sides, and a spring plate and an elastic member are provided on the opposing surfaces of the rail and the electric device.

[Effect]

In this invention, a spring plate provided on a rail or an electric device is embedded in and locked with an elastic member provided on its counterpart, and is firmly connected by the meshing force, so that the electric device does not wobble or slide on the rail. prevent this from happening.

[Example] Below, FIGS. 1, 2, and 3 show an example of this invention.
This will be explained based on the diagram. In the figure, the difference from the conventional one is that a flexible elastic member 7 such as rubber with a large friction coefficient is attached to the bottom surface 102 of the rail 1, while a steel plate or the like is attached to the groove bottom surface 31 of the electrical equipment 2. The spring plate 6 is fixed by caulking or the like, and a jagged edge 61 is formed at the free end of the spring plate 6. Other configurations (as they are the same as the conventional ones, the explanation will be omitted.

Next, the manner in which the electrical equipment 2 having the spring plate 6 and the elastic member 7 and the rail 1 are attached will be explained.

As shown in Figure 2, a fixing claw 4 is attached to one edge +01 of the rail 1.
When the device 2 is hooked in the direction of arrow A and the device 2 is pushed in the direction of arrow B, the movable claw 5 moves back and forth in the direction of arrow C to pass the other edge 101 of the rail 1 and connect with the fixed claw 4 as shown in FIG. The edge 101 of the rail 1 is pressed and clamped by the movable claw 5, and the equipment 2 is moved.
Mounted on Le 1.

In the attached state shown in FIG. 3, the serrated blade 61 of the spring plate 6 is pressed against the elastic member 7 and is engaged with the elastic member 7 with difficulty. By the engagement of the spring plate 6 with the elastic member 7, the 81 device 2 is firmly fixed on the rail 1 via the elastic members 6 and 7. Therefore, the equipment 2 does not rattle on the rail 1 or slide on the rail l and fall off the rail 1 unlike in the conventional equipment.

In the above embodiment, the free end of the spring plate 6 is provided with a serrated blade 61, but a smooth blade without a serrated blade may also be used. Furthermore, the installation direction of the spring plate 6 may be changed by <90° as shown in FIG. 4(a), or the jagged edge 61 of the spring plate 6 may be provided on only one side as shown in FIG. 4(b). . Furthermore, as shown in FIG. 4(c), the spring plate 6 may be provided on the rail 1, and the elastic member 7 may be provided on the machine Wj2 side.

〔Effect of the invention〕

As described above, according to the present invention, the simple structure of attaching a spring plate and an elastic member to the opposing surfaces of the rail and the device prevents the device 2 from sliding on the rail 1 and falling off the rail 1, unlike the conventional device. This also prevents the equipment 2 from shaking on the rail 1.

Claims (2)

[Claims] (1) In a rail mounting device for electrical equipment in which electrical equipment is held on the rail by pressing and pinching the protruding edges on both sides of the rail, a steel plate is attached to one of the opposing surfaces of the rail and the electrical equipment. When an electrical device is mounted on the rail by attaching an elastic member such as rubber to the other side, the free end of the spring plate gets wedged in the elastic member, making it impossible for the electrical device to slide on the rail. A rail mounting device for electrical equipment, characterized in that it can be mounted on a rail. (2) The rail mounting device for electrical equipment according to claim 1, wherein a serrated blade is formed at the free end of the spring plate.
