Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a t-Ti electrical equipment mounting structure 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 equipment 2 is placed on the rail 1 by pressing and holding the protruding edges I01 on 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 pawls 4 and 5 are made of polyacetal resin. The holding power in the longitudinal direction of the rail 1 is particularly promising due to the fact that it is formed of N& and the large variation in the plate thickness of the rail 1.
The device #2 easily slides on the rail 1 in the longitudinal direction of the rail 1 and falls off the rail 1, and the equipment 2 rattles 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 an electric gFcam installed so as to sandwich the rail having a diagonal cross section from both sides.
is attached to a rail, and a large number of protruding ribs that engage with each other are provided on both the receiving surfaces (top surfaces) of the protruding edges provided on both sides of the rail and the bottom surface of the device.

[Effect]

In this invention, the protruding ribs of the rail engage and are fixed with the protruding ribs on the bottom surface of the electrical device, so that the electrical device can be prevented from shaking or sliding on the rail.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3. In Figures 1, 2, and 3, the difference from the conventional one is that the l
A large number of protruding ribs 103 are arranged in the longitudinal direction on the receiving surface (upper surface) 102 of the i 101, and the bottom surface 31 of the groove 3 placed on the receiving surface 102 of the rail 1 is also provided with F.
The point is that a large number of protruding ribs 32 in a direction perpendicular to tIt3 are arranged in a direction parallel to the groove 3.

In the above mounting structure, the receiving surface 10 of the rail 1
A protruding rib 103 is provided on the bottom surface 31 of 2 and *li2, respectively.
．． 32, the device 2 is held on the rail 1 by sandwiching the edge 101 of the rail 1 between the fixed claw 4 and the movable claw 5, and the protruding rib 103 of the receiving surface 102 of the rail 1 and the device 2 The protruding ribs 32 on the bottom surface 31 of the rails 1 and 2 engage with each other to prevent the equipment 2 from sliding in the longitudinal direction of the rail 1.

〔Effect of the invention〕

As described above, according to the present invention, the protruding rib 1 of the rail 1
Since the protruding ribs 32 on the bottom of the rail 1 and the equipment 2 are engaged with each other and fixed, measures such as increasing the dimensional accuracy of the parts related to the mounting of the rail 1 and the equipment 2 and increasing the elasticity of the elastic arms can be taken. This makes it possible to more reliably prevent the machine Pj2 from sliding without taking any measures.

[Brief explanation of drawings]

Figures 1, 2, and 3 show an embodiment of the invention, in which Figure 1 is a perspective view of the rail, Figure 2 is a sectional view showing the bottom of the equipment, and Figure 3 is a cross-sectional view of the bottom of the equipment. are cross-sectional views showing the equipment installed on the rail, Figures 4, 5, and 6r! ! J shows a conventional device of this kind; FIG. 4 is a perspective view of the rail, FIG. 5 is a perspective view of the movable claw portion, and FIG. 6 is a sectional view showing the mounting structure. In the figure, 1 is the rail, 2 is the equipment, 3 is the groove, 3] is the bottom, 3
2 is a protruding rib, 4 is a fixed claw, 5 is a movable claw, 51 is an elastic arm, 101 is an edge, 102 is a receiving surface, and 103 is a protruding rib. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Claims] In a rail mounting device for electrical equipment in which the electrical equipment is held on the rail by pressing and pinching the protruding edges on both sides of the rail, the receiving surfaces (top surfaces) of the edges on both sides of the rail.
and a bottom surface of the rail storage groove of the device that comes into contact with the receiving surface, and a plurality of protruding ribs that are formed perpendicularly to the groove and engage with each other are provided on both sides.
