Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electromagnetic switch mounting structure for vibration-proof mounting of the electromagnetic switch to a control panel or the like.

[Prior art]

When an electromagnetic switch is installed on a control panel of a device that vibrates, it is generally installed by inserting a vibration isolator into the mounting part. Fig. 1 is a side view of this type of conventional mounting structure, and Fig. 2 is a front view of the same.
is fixed on the mounting plate 2 which is integrally formed with the board 2a and the vertical edge 2b, while the 4 on the control panel 3
A pair of L-shaped fixtures 4 are fixed to each corner by set screws 5. The vertical edges 2b of the mounting plate 2 protrude in four directions from the board 2a, and vibration-proofing rubbers 6 are fitted into these protruding parts, and each vibration-proofing rubber 6 is clamped and fixed with a fixing metal 4. By tightening the screws 7, the electromagnetic switch 1 is fixed to the control panel 3 together with the mounting plate 2.

However, in such a conventional mounting structure, not only is there a large number of parts, which increases material and processing costs, but also the electromagnetic switch 1 is fixed after many fixing metals 4 are screwed onto the control panel 3. Mounting plate 2
must be supported together with the vibration isolating rubber 6 and fixed with screws, which has the disadvantage that the installation work is troublesome and takes a long time.

[Summary of the idea]

The present invention was devised in view of the above points, and the mounting plate to which the electromagnetic switch is fixed is engaged with and supported by the U-shaped grooves of the fixing member installed upright at the four corners of the member to be attached. By inserting a vibration isolating material between the facing edge of the mounting plate and the facing surface of the fixing member and fixing it with bolts and nuts, the number of parts can be reduced and the installation work can be easily and quickly completed. The present invention provides a mounting structure for an electromagnetic switch that makes it possible. Embodiments of the present invention will be described in detail below with reference to the drawings.

[Example of idea]

Figures 3 to 5 show an embodiment of the electromagnetic switch mounting structure according to the present invention, with Figure 3 being a side view, Figure 4 being a front view, and Figure 5 being an enlarged perspective view of the main parts. It is a diagram. In these figures, the electromagnetic switch 11 consists of a board 12a and vertical edges 12b on both sides of the board 12a.
It is fixed on a mounting plate 12 that is integrally formed with a U-shaped groove 12c that opens toward the edge at both ends of each vertical edge 12b. on the other hand,
A pair of fixing plates 14 bent into a U-shape are fixed to two places on the surface of the control panel 13 as a member to be attached with set screws 18. A U-shaped groove 14b is provided to engage the base plate 12a of the mounting plate 12. The engaged raised edges 12b of the mounting plate 12 and the raised edges 14a of the fixing plate 14 are opposed to each other, and a cylindrical shape is formed between the compatible edges 12b and 14a of the opposing parts. A vibration isolating rubber 15 is inserted as a vibration isolating material, and a bolt 16 passing through the center hole of the vibration isolating rubber 15 is inserted into a U-shaped groove 12c of the vertical edge 12b and a bolt hole provided in the vertical edge 14a. It is inserted. A nut 17 is screwed into the threaded portion of the bolt 16 protruding from the vertical edges 12b, 14a, and by tightening this, the mounting plate 12 and the fixed plate 14 are fixed via the vibration isolating rubber 15. .

In the mounting structure configured as described above, in order to mount the electromagnetic switch 11 on the control panel 13, the base plate 12a of the mounting plate 12 on which the electromagnetic switch 11 is fixed is engaged with the U-shaped groove 14b of the fixing plate 14. Thereafter, the fixing plate 14 is fixed to the control panel 13 with the set screws 18, and the vibration isolating rubber 15 is inserted between the compatible edges 12b and 14a.
Then, the bolt 16 is inserted, a nut 17 is screwed onto the threaded portions at both ends of the bolt 16, and the nut 17 is tightened to complete the installation.

In this embodiment, the control panel 13 and the fixing plate 14 are provided separately and fixed with the setscrews 18. A fixing member corresponding to the upright edge 14a may be formed by punching out the blank and bending it at right angles. In addition, in this embodiment, the anti-vibration rubber 15
Although an example is shown in which a separate bolt 16 is inserted, it is also possible to use a conventionally well-known structure in which threaded discs are bonded to both end surfaces of the vibration isolating rubber 15 and the vibration isolating rubber 15 and the threaded portion are integrated. Good too.

[Effect of idea]

As is clear from the above explanation, in the mounting structure of the electromagnetic switch according to the present invention, the mounting plate on which the electromagnetic switch is fixed is connected to the U-shaped groove of the fixing member provided upright at the four corners of the member to be mounted. The number of parts can be reduced by supporting the parts together, inserting a vibration isolating material between the facing surfaces of the upright edge provided on the mounting plate and the front fixing member, and fixing them with bolts and nuts. Machining becomes easier and material costs and processing costs can be reduced, and installation work is also easier than before, improving work efficiency and reducing labor. In addition, even if the vibration isolating material deteriorates or is damaged, the movement range of the mounting plate is restricted by engagement with the U-shaped groove, so the electromagnetic switch will not fall off and its damage will be prevented. It can be prevented.
