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 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 equipment 2 is held on the rail 1 by pressing and pinching edges 101 protruding from both sides of 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 distance between the rail 1 and the pawl 4.5 is j! J-friction differential coefficient members, for example, rail 1 is made of aluminum, claws 4 and 5
This is due to the fact that the rail is made of polyacetal resin and that the thickness of the rail 1 varies widely.
The holding force in the longitudinal direction of the rail 1 is not particularly expected, and the machine 1g2 is held on the rail 1 in the longitudinal direction (the 5th
It may easily slide in the direction of the target and fall off the rail,
It has drawbacks such as the equipment 2 shaking on the rail 1.

Otsu's invention was made to solve the above problem, and after installing the electric device on the rail, the electric 45! This prevents the i-device from sliding in the longitudinal direction of the rail.

[Means for solving problems]

A rail mounting device for electrical equipment according to the present invention is for mounting an electrical equipment on a rail so as to sandwich the rail having a peeled cross section from both sides, and has a spring plate and projections and depressions that engage with the spring plate on the opposing surfaces of the rail and the electric device. It was established.

[Effect]

In this invention, the spring plate provided on the rail or the electric 9Aam device engages and locks with the unevenness provided on the other side, and is firmly connected by the engagement force, preventing the electrical equipment from rattling or sliding on the rail. prevent this from happening.

[Example] Below, FIGS. 1, 2, and 3 show an example of the present invention.
This will be explained based on the diagram. A spring plate 7 made of a steel plate or the like is attached to the bottom surface 102 of the rail 1 by means such as welding, and its upper end protrudes above the edge 101 of the rail 1.
t) A serrated blade 71 is provided on the edge surface. On the other hand, the groove bottom surface 31 of the electric device 2 is provided with unevenness 6 in a direction orthogonal to the longitudinal direction of the rail 1, which engages with the serrated blade 71. The rest of the configuration is the same as the conventional one, so the explanation will be omitted.

Next, the installation H of the electrical equipment 2 and the rail 1 in the above configuration
I will explain about you. As shown in FIG. 2, when the fixed claw 4 is hooked on one edge 101 of the rail 1 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 move the rail 1. The other edge 101 of the rail 1 is passed through, and the edge 101 of the rail 1 is pressed and clamped by the fixed claw 4 and the movable claw 5 as shown in FIG. 3, and the equipment 2 is mounted on the rail 1. Here, in the installed state shown in the third figure, the jagged blade 7N of the spring plate 7 is
! It engages with the unevenness 6 of the groove bottom surface 31 of the jjl device 2 and is pushed into the rail 1 by the groove bottom surface 31. That is, the jagged blade 71 of the spring plate 7 engages with the unevenness 6 and sinks into the groove bottom surface 31 due to its own elasticity, and the device 2
This means that it is firmly fixed on the rail 1 via the spring plate 7. Therefore, the equipment 2 does not rattle on the rail or slide on the rail 1 and fall off the rail 1 unlike in the conventional equipment.

In the above embodiment, the spring plate 7 is formed in the shape of a mouth, but it may be formed in the shape of an opening as shown in FIG. 4(A), for example. Furthermore, as shown in the same figure (b), the spring plate 7
may be provided on the equipment 2, and the unevenness 6 may be provided on the rail 1. In this case, as shown in (c), a spring plate 7 formed in an Lj shape is provided with the free end 71 of the spring plate 7 perpendicular to the longitudinal direction of the rail 1. It may be provided in the device 2 as shown in FIG. In this case, it is not necessary to provide the free end 71 of the spring plate 7 with a serrated edge.

〔Effect of the invention〕

As described above, according to the present invention, by providing a simple configuration in which unevenness is provided on the opposing surface of the rail and the equipment to engage the spring plate, the TLL device 2 slides on the rail 1 as in the conventional device, and the Leno 11 81 on rail 1.
It is normal for container 2 to shake.

[Brief explanation of drawings]

Figures 1, 2, and 3 show one embodiment of the present invention. Figure 1 is a perspective view, Figures 2 and 3 are sectional views showing the mounting structure, and Figure 4 (illustration). )(B)(C) are perspective views showing other embodiments of the present invention, FIGS. 5, 6, and 7 show conventional devices of this type, and FIG. 5 is a perspective view of a rail. , 6th
Figure 7 is a perspective view of the movable claw part, and Figure 7 is a cross-sectional view showing the mounting structure. In the groove bottom surface, 4 is a fixed pawl, 5 is a movable pawl, 51 is an elastic arm, 6 is an unevenness, 7 is a spring plate, and 71 is a serrated blade.In addition, the same reference numerals in the drawings indicate the same or equivalent parts.

Claims (2)
