Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a mounting device for electrical equipment that is attached to a support such as a utility pole.

[Conventional technology and its problems]

Conventionally, when a mounting device for an electrical device is brought into contact with a support column, the size of the mounting seat is approximately the same as that of the electrical device, and the abutment surface is made to contact as widely as possible. By widening the contact surface, the support point is located at the outer edge of the electrical device, so even if the contact surface has some unevenness, it will have little effect on the installation posture of the electrical device. This was due to the fact that no problem occurs even if the strength of the mounting seat or the strength of the support mounting surface is small. However, in recent years, there has been a trend to downsize mounting devices to make them less conspicuous from the perspective of beautifying the pillars. If the support condition is poor, problems such as the electrical equipment tilting or wobbling may occur, and there is a risk that the installation condition may become unstable.

As an example of a conventional mounting device, for example,
-There is one shown in Publication No. 1883. This conventional example will be explained based on the drawings in the same publication. Regarding the structure for attaching capacitors and other power distribution equipment to utility poles etc., side plates 5, 5 of the mounting bracket 4 on which the equipment 10 is mounted
Cut grooves 7, 7 are provided in the wing pieces 6, 6, and the cut grooves 7,
By inserting a tightening band 2 into 7, it is tightened and fixed to the utility pole 1.

The blades 6, 6 of the mounting bracket 4 are curved so as to be joined to the circumferential surface of the pole 1, and their joining surfaces 9, 9 are in surface contact with the mounting surface of the utility pole 1.

In this case, the mounting bracket 4 is in surface contact with the utility pole 1, and if the mounting surface is uneven, it is undeniable that the mounting becomes unstable. Furthermore, although the device 10 is a capacitor or other power distribution device, looking at its size, weight, and the state of attachment between the device and the mounting bracket according to the drawings in the same publication, the attachment part of the mounting bracket 4 to the device 10 is 10, and the mounting bracket 4 is large in size. Furthermore, in view of the mounting state of the mounting bracket 4 and the equipment 10 on the utility pole 1, there is a problem when the mounting device equipment 10 of the publication is a large and heavy object. That is, the cut groove 7 (see Figures 2 and 3 of the same publication) or the through hole 15 (see Figure 4 of the same publication) for passing the tightening band 2 through the mounting bracket 4.
is biased downward, and the holding force against the rotational torque exerted by the weight of the device 10 on the mounting surface of the mounting bracket 4 is weakened. do not have.

Further, as another example of a conventional mounting device, there is one shown in FIG. In the figure, an electrical device 1 consists of a case 2 and a cover 3. The case 2 is open at the bottom, and built-in components are attached to a mounting frame (not shown) fixed inside the case 2. The cover 3 opens at the top, covers the built-in parts of the case 2, fits onto the case 2, and is tightened with screws 4. Reference numeral 5 denotes a mounting seat, and a base 5a and a base 5 are fixed to the case 2.
It consists of leg portions 5b, 5b extending left and right from a.
A post band through hole 5c is provided at the tip of the base 5a.
is formed into a slit shape. Reference numeral 6 denotes a hanging fitting for hoisting the electrical equipment 1, which is fixed to the case 2 by welding or the like.

In the conventional device with such a configuration, when fixing to the column with the column mounting band, the left and right legs 5b of the mounting seat 5,
The mounting surface of 5b is designed to abut as widely as possible along the cylindrical circumferential surface of the support column, but if the circumferential surface of the support column is uneven, it may tilt or wobble, making the mounting surface unstable. As a result, mounting the poles is difficult and takes a long time, and unreasonable force is applied to the mounting base, creating problems such as increasing the dimensions and thickening the steel plate to improve strength. Ta. Furthermore, since the mounting seat and the hanging fitting are prepared separately, there are disadvantages such as an increase in the number of parts, an increase in the number of processing steps such as welding to attach them, and a complicated appearance.

[Problem that the invention attempts to solve]

In view of these points, the present invention is designed to provide a mounting device for attaching electrical equipment to the body of a support column, in order to balance the overall external shape of the case 2 or the electrical equipment 1 and improve its appearance, from the viewpoint of aestheticizing the installation of the support. 5
By downsizing and maintaining sturdiness to support the weight of electrical equipment, and by reducing the area of contact with the support column and by floating the area other than the contact area above the support mounting surface, the support of the contact area is also improved. The mounting condition is stabilized by maximizing the distance within the dimensional range of the mounting seat.

Further, the present invention provides a mounting device for electrical equipment that integrates the mounting seat and the hanging metal fittings, reduces the number of parts, reduces the number of processing steps, and has a clean appearance.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a mounting device for attaching an electrical device to the body of a support column, by providing a pair of left and right legs along the support column as the contact portion of the mounting seat to the support column, and Bend the tip of the holder outward, and use this bent corner as the contact part with the support.
The central part of this abutting part is a protruding part that protrudes to the side opposite to the abutting surface, and both ends are formed as protrusions, and there are four protrusions on the left, right, top, and bottom along the circumferential surface of the support of the mounting seat. The part is formed so that the abutting part with the peripheral surface of the support can be contacted in a small area such as a point contact or a short line contact. Furthermore, a large-diameter plate hole for lifting is provided in the mounting seat so that a hanging fitting is omitted.

〔Example〕

The present invention will be explained in detail below. FIGS. 2 to 6 show embodiments of the present invention, and parts that are equivalent or equivalent to those of the conventional example shown in FIG. 1 are designated by the same numbers. In the figure, the left and right legs 5 of the mounting seat 5
The tips of b and 5b are bent outward to make the corner part a contact part that comes into contact with the peripheral surface of the support, and in the center part excluding both ends of this contact part there is an overhanging part 5 that overhangs on the side opposite to the contact surface.
e is provided to reinforce the legs 5b, 5b, and four projections 5f are provided at both upper and lower ends of the left and right legs 5b, 5b.
form as. The protruding portion 5f is in contact with the circumferential surface of the support column 8, and the central portion thereof is in a floating state from the circumferential surface of the column. In addition, the hanging fitting 6 of the conventional device is deleted, and instead, a large diameter hole 5d is connected to the through hole 5c so that a lifting wire or a hook can be hung on the upper part of the through hole 5c of the pillar band 7 of the mounting seat 5. and set it up.

[Effect of idea]

As described above, the present invention provides a mounting seat for attaching electrical equipment to the body of a support column, and provides a pair of left and right legs along the support column as the abutting portion of the installation seat to the support column, and removes the tip of each leg. Bend it towards the side, make the bent corner the contact part with the pillar, make the center part of this contact part an overhanging part that protrudes to the side opposite to the contact surface, and form the remaining both ends as protrusions. Therefore, the contact portion of this protrusion with the peripheral surface of the column contacts the peripheral surface of the column in a small area such as approximately point contact or short approximate line contact, and,
The support distance between the abutment part and the support column can be maximized within the dimensional range of the mounting seat, and the central part of the abutment part is kept floating from the abutment surface due to the overhang process. A stable mounting condition can be obtained without being affected by irregularities on the circumferential surface of the column. In addition, the legs are reinforced by the overhanging process of the above-mentioned overhang, so there is no need to increase the thickness of the mounting seat more than necessary, and electrical equipment can be supported with a small and lightweight mounting seat, saving installation space. , you can improve your appearance. Furthermore, by integrating the mounting seat and the hanging fitting, it is possible to reduce the number of processing steps, simplify the external structure, and obtain a mounting device for electrical equipment with a clean appearance.
