Description

[Detailed description of the invention] Industrial application field This invention relates to a device for fixing electrical equipment to a rail, which can fix electrical equipment used in control panels, etc. to the rail with a single touch.It reduces the number of parts and has a simpler structure. To obtain a mounting device that is simplified and miniaturized.

PRIOR ART A proposed structure for mounting this type of electrical equipment on a rail is Japanese Utility Model Publication No. 54-10455, but this structure involves engaging a slider that receives a spring force with a protrusion or groove provided on the electrical equipment. At the same time, the slider is attached to the rail by engaging it with the force based on the spring force. This structure requires a spring part to press the slider, and it is difficult to compress the spring during assembly. The drawback was that it was difficult to assemble as it required the work of attaching the slider.

Embodiment The present invention has been proposed in view of the above-mentioned contents, and will be explained below with reference to the drawings. 1 is an electrical equipment main body, 2 is a mounting plate fixed to the bottom of the electrical equipment main body 1, and 3 is one of the bottom parts of the mounting plate 2. The side wall protrudes downward, 4, 4 is a locking protrusion that protrudes inward from the side wall 3, 5 is a V-shaped rail, and has mounting parts 6, 6, one mounting part 6 is connected to the bottom surface of the mounting plate 2. The locking projections 4 and 4 can be locked together.

7, 7 is a sliding wall formed on the other side of the bottom of the mounting plate 2 at a position facing the side wall 3, and has grooves 8, 8 facing each other between the bottom surface of the mounting plate 2, and 9, 9 are *8. .8 is a recess located below, 10 and 10 are locking pillars formed on both sides of the mounting plate 2 with gaps 11 and 11 in between the sliding walls 7 and 7, and 12 and 12 are at the ends of the mounting plate 2. Grooves 14, 1 facing each other across the sliding gap 13
4, a guide wall 15 is a recess provided approximately in the middle between the recesses 9, 9 of the mounting plate 2, and a protrusion 17 having a slope 16 is formed in the recess 15.

Reference numeral 18 denotes a fixture that forms a horizontal portion 20 at the end of the central sliding portion 19, and has locking portions 21, 21 at the ends of the horizontal portion 20 facing the locking protrusions 4, 4 of the side wall 3.

The horizontal portion 20 has sliding locking portions 22, 22 at the upper and lower ends thereof to be slidably locked in the grooves 8°8 of the sliding walls 7, 7.
Locking protrusions 23, 23 are formed above 22 to fit into the recesses 9.9 of the mounting plate 2.

24.24 is a spring body formed on both sides of the central sliding part 19 across the groove 25.25, and both end sides are the locking posts 10 of the mounting plate 2.
, 10.

26, 26 are guide sliding walls formed on both sides of the central sliding portion 19, and can be slidably locked in the grooves 14, 14 of the guide walls 12, 12 of the mounting plate 2.

27 is a recess formed in the upper part of the other end of the central sliding part 19; 2B;
A locking piece having a slope 29 formed at the upper center of the horizontal portion 20 moves within the recess 15 of the mounting plate 2 and locks onto the protrusion 17 .

Next, to explain how to attach the fixture 18 to the mounting plate 2, as shown in FIG.
8, and the other end of the center sliding part 19 is placed between the guide wall 12 and the horizontal part 20 of the center sliding part 19 and the spring body 24.
, 12 into the sliding gap 13 between the locking protrusions 23, 23.
Insert the fixture 18 into the recess 9°9, aligning it with the slope 29 of the locking piece 28 on the slope 16 of the protrusion 17 in the recess 15, as shown in FIG. Since the locking piece 28 does not slide on the slope 16, the locking piece 28 gets over the protrusion 17, and the locking piece 28 locks the protrusion 17 as shown in FIG. The locking protrusions 23, 23 are movable in the recesses 9, 9, and the locking protrusions 23, 23 lock on the left side of the recesses 9, 9, and the fixture ■ will not come off to the left, and the central sliding part 19
can slide in the sliding gap 13 between the guide walls 12, 12, and the guide sliding walls 26, 26 are slidably locked in the grooves 14, 14 of the guide walls 12, 12, as shown in FIG. As shown, the fixture 18 is attached to the mounting plate 2 so as not to come off.

Next, to explain how to attach the electrical equipment main body 1 to the rail, one mounting part 6 of the rail 5 is engaged between the bottom part of the mounting plate 2 and the locking protrusions 4, and the other mounting part of the rail 5 is When the slope portion 30.30 of the locking portion 21.21 of the fixture 11 is pressed against the end of the fixture 11, the fixture 11 moves to the left against the elasticity of the spring body 24.24, and the mounting portion 6 When it reaches the bottom of the mounting plate 2, the fixture 11 moves to the right by the force of the spring bodies 24, 24, and the mounting portion 6 is sandwiched between the bottom of the mounting portion 2 and the locking portions 21, 21, and is fixedly attached.

To remove the electrical device main body 1 from the rail 5, a screwdriver or the like can be inserted into the recess 27, and the fixture 11 can be moved to the left and removed.

Effect of invention As described above, the present invention has the following effects.

(1) Since the spring bodies 24 and 24 integrally formed with the fixture 18 are used to press the fixture 18 against the rail 5, costs can be reduced without using extra spring parts.

(2) Since the fixing tool (■) can be attached to the mounting plate 2 by simply pushing it in, assembly can be done quickly and reliably.

(3) Since the height dimension of the fixing device portion of the mounting plate 2 to which the fixing device 18 is attached is reduced in a reciprocal manner, the main body of the electrical equipment can be miniaturized and can be easily used in a control panel or the like.
