JPS5812526Y2 - Box for pole-mounted equipment - Google Patents

Description

[Detailed description of the invention] This invention is suitable for use in, for example, a pole-mounted switching connection board that switches and connects a feeder cable unit and a distribution cable, or a case for a CATV relay panel installed on a pole. The present invention relates to an improvement of a box that has a space for storing pole-mounted equipment and is used by being installed on a pole.

Generally, as shown in Figure 2, this type of box is cut out from the rectangular main body of the box, so the value of its width W must be made as small as possible.

However, if the width W of the box is made smaller, its volume also becomes smaller, so in the case of a switching connection board, the number of feeder cable terminals must be reduced, making it impossible to respond to an increase in the number of subscribers.

Further, as shown in FIG. 2, the conventional box main body 1 has side walls 2
, 2 are connected via hinges 3, 3 to the respective front ends of the double doors 4, which open and close from the front center to the left and right.
It is equipped with a door 5 that warns from 4.

However, with this structure, when workers connect or switch cables inside the box, they have to work between the letters in the narrow space between the back wall of the box itself. Not only is it difficult to work, but the distance from the center of the utility pole required for opening and closing the door 5 is also small.
Because of the large size, the worker is on a platform with poor footing, so when opening and closing the door sections 4, 4, the worker must approach the edge of the platform by the length in the width direction of the door sections 4, 4, so that the worker can work safely. I can't.

An object of the present invention is to provide a column-mounted equipment case that reduces wind pressure load without reducing storage volume and allows workers to work safely.

An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a box 10 according to the present invention, which has a main body 13 having a back wall 12. The main body has a telephone pole attachment space 14 recessed inwardly in the back wall 12.

The box 10 is fitted into the utility pole mounting space 14 so as to surround half the circumference of the utility pole 16, and is attached to the utility pole 16 by being tightened with a band (not shown) or the like.

Therefore, as shown in FIG. 1, since the depth of the box 10 is increased, the width (opening) of the box 10 can be reduced for the same volume.

That is, even if the width W2 of the box 10 is made smaller than the width W□ of the conventional box 1 and the volumes 1 and V2 on both sides of the box main body 13 shown by broken lines in FIG. Volume V1',
Since ■2' supplements the volumes ■□ and ■2, the box 10 can have the same volume as the conventional box 1, and therefore the box 10 has the same volume as the conventional box 1. However, since the width W2 is smaller, the wind pressure load can be smaller than before.

The box 10 of the present invention, as shown in FIG. A locking means (not shown) such as a lock is attached to the front surface of the door 24.

Therefore, the pair of door portions 22.22 are connected to the side wall 18 and the stop wall 26.
It consists of

These door portions 22.22 have a double door structure that can be opened and closed from the center of the front to the left and right, but these door portions can be opened left and right using both ends of the back wall 12 as fulcrums, as shown by the broken lines in Figure 1. The length of the door portion 22゜22 protruding forward is small, and the length from the center of the utility pole 16 is L2 (
<Ll) is enough.

As described above, since the door portions 22.22 of the case 10 of the present invention protrude from the case 10 with a small length, the operator can open and close the door portions 22.22 closer to the case 10 than in the past. This allows workers to work more safely on the platform.

According to the present invention, as mentioned above, since a space for attaching a utility pole is provided on the back wall, the depth of the box can be increased without protruding forward, and therefore, the volume of the box can be increased without reducing the volume of the box. Since the width of the box can be reduced, the wind pressure load that the box receives can be reduced, and the door is supported on both sides of the back wall so that it can swing freely.
Since it is cut out from the pair of abbreviated door parts, the length of forward protrusion of the door part when opening and closing the door part is small, and therefore the operator can move closer to the box to open and close the door part. This makes it possible to work more safely than in the past, and it is also easier to work in the corners of the box.
