Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electrical equipment fixing device for attaching electrical equipment to a fixed part.

[Conventional technology]

When installing electrical equipment such as a proximity switch, photoelectric switch, or non-contact switch in a predetermined location, conventionally, as shown in Fig. 1, a strip-shaped fixing device is used, which is bent so as to straddle the electrical equipment 1. The horizontal parts 20 at both ends of the instrument 2 are fixed with screws 6 screwed into the mounting surface.

[Problem that the invention attempts to solve]

Although such a fixing means is extremely simple and can be provided at low cost, when several electrical devices 1 are to be mounted in close proximity to each other as shown in FIG. 2, the fixing device 2 cannot be used.

This idea was made to eliminate the inconvenience of installing electrical equipment. Even if several electrical equipment are fixed in parallel in close proximity, the fixtures used to fix each of them may get in the way of each other. To provide a practical electrical equipment fixing device that can be installed without any problems.

[Means for solving problems]

The electrical equipment fixing device according to this invention includes a pressing plate whose lower surface abuts the upper surface of the electrical equipment, and sleeve plates that are connected to the left and right side edges of the pressing plate and formed respectively along both sides of the electrical equipment. These sleeve plates are provided with a rear part of the sleeve plate extending to the side opposite to the electrical equipment, and a mounting plate formed inwardly of each sleeve plate at the lower end of the rear part of the sleeve plate, and this mounting plate and each sleeve plate are provided with Position the bottom edge of each plate so that it is above the bottom of the electrical equipment, and install the screw holes located between the end of the mounting plate opposite to the electrical equipment and the electrical equipment. It is mounted on a board.

[Effect]

In this invention, when a screw is passed through the insertion hole of the mounting plate and screwed in, the mounting plate is pushed down using the end of the mounting plate as a fulcrum, and this causes the pressing plate to press against the top surface of the electrical equipment, ensuring firm installation. It will be done.

〔Example〕

3 and 4 are a perspective view and a side view of an installed state of an embodiment of this invention. In this figure, the electrical equipment fixing device includes a pressing plate 3 whose lower surface abuts the upper surface of the electrical equipment 1, and is connected to the left and right side edges 3a of the pressing plate 3, and extends along both side surfaces 1a of the electrical equipment 1. toward the inner side of the lower end portions 40a, 40a of the hanging sleeve plates 4, 4 and the rear portions 40, 40 of the sleeve plates 40, 40, which are the parts that extend to the rear of both the sleeve plates 4, 4, that is, to the side opposite to the electrical equipment 1. It is formed.
And the lower end portions 40a, 4 of the sleeve plate rear portions 40, 40.
A mounting plate 5 is integrally formed inward at 0a,
This mounting plate 5 is provided with screw holes 50. 5
Reference numeral 1 denotes a support leg, which is provided near the end of the mounting plate 5 on the side opposite to the electrical device 1.

The mounting plate 5 shown in FIG. 3 is a single plate that connects the rear parts 40, 40 of both sleeve plates, and the mounting plate 5 shown in FIG.
The figure shows an example in which the parts are extended in alternating positions in the front and back.

As can be seen in FIG. 4, the lower sides 4a of the sleeve plates 4, 4 and the mounting plate 5 are located somewhat above the bottom of the electrical equipment 1, and therefore the screw holes 5 of the mounting plate 5 are located slightly above the bottom of the electrical equipment 1.
0, screw the screw 6 into the screw hole of the fixing part 7 that fixes the electrical device 1, and attach the electrical device 1 to the fixing part 7 with a fixing device.
Since the mounting plate 5, which is located somewhat above the mounting surface, is pushed down to the fixing part 7 surface by the screws 6, the entire fixing device is also pushed down, and the electrical equipment 1 is firmly attached to the fixing part. 7. Fix it on top.

In this case, since the fixing device becomes inclined in the direction of the screw 6, the tip of the electrical device 1 tends to rise. Therefore, in order to prevent this, a part of the rear edge 5a of the mounting plate 5 is made to protrude downward, and the support leg 51
If the screw hole 50 is positioned between the support leg 51 and the electrical device 1, then when the screw 6 is tightened, the front end of the press plate 3 will be pushed toward the fixed part 7 surface using the support leg 51 as a fulcrum. produces pressure. When there is no supporting leg 51, the rear edge 5a of the mounting plate 5 abuts on the fixed part 7, and this becomes a fulcrum.

The mounting plate 5 of the fixing device in the embodiment shown in FIG. 3 becomes narrower as the electrical equipment 1 becomes smaller, so two screw holes 50, 50 are formed in the mounting plate 5. It is difficult to install the screw 6, and since the electric device 1 has a cord 10 extending to the rear, the cord 10 gets in the way.
It also becomes very difficult to screw in the screws. The embodiment shown in FIG. 5 solves this problem, that is, the mounting plates 5, 5 are attached to the rear portions 40, 4 of both sleeve plates 4, 4.
The screw holes 50', 50' are formed in the mounting plates 5, 5 formed in this way so as to face each other, and the positions of the protrusions are different from the front and back. It is formed in such a way that it separates from the
This structure has the advantage that the screw hole 50' can be easily drilled, and the screw 6 can be screwed in quickly without the cord 10 getting in the way. In addition, the mounting plates 5, 5 shown in FIG. 5 are formed by forming one mounting plate 5 longer in the front and back direction in the one shown in FIG.
The screw hole to be drilled in it is screw hole 5 in Figure 5.
It may be provided at the same position as 0' and 50'.

Although the electric device 1 is shown as having a rectangular cylindrical shape, it goes without saying that the device of the present invention can also be applied to fixation to a cylindrical device.

[Effect of idea]

As described above, the electrical equipment fixing device of this invention includes a pressing plate whose lower surface abuts the upper surface of the electrical equipment;
A sleeve plate that is connected to the left and right side edges of this pressing plate and formed along both sides of the electrical equipment, a rear part of the sleeve plate that extends to the side opposite to the electrical equipment on these sleeve plates, and a rear part of this sleeve plate. A mounting plate is provided at the lower end of each sleeve plate and is formed toward the inside of each sleeve plate, and the mounting plate and the lower edge of each sleeve plate are both positioned above the bottom of the electrical equipment. In addition, screw holes located between the end of the mounting plate on the opposite side of the electrical equipment and the electrical equipment are provided in the mounting plate, so there is no large overhanging part on both the left and right sides of the electrical equipment, and the electrical equipment Several pieces can be installed closer together as shown in Figure 2 or even closer together.
This has the advantage that it can be used as a practical fixture for incorporation into small electric machines.
