Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention is a split plate holder that is installed at the bottom of a multi-circuit switch for high-voltage lead-in that is installed above ground when electric cables in urban areas are buried underground. It is related to.

(Prior Art) In recent years, electric cables in urban areas have been buried underground from the perspective of urban beautification. In that case, a multi-circuit switch for high-voltage lead-in, which houses a transformer, cable terminal, control box, etc., is installed on the ground.

At the bottom of this high-voltage lead-in multi-circuit switch, a large number of dividing plates are provided with holes for passing various cables, and the dividing plates are fixed by dividing plate holders. The divided plate presser had a U-shaped cross section and an elongated shape, and its base end and distal end were fixed with bolts.

(Problems to be Solved by the Invention) The above-mentioned conventional split plate holder had both the base end and the distal end fixed with bolts, making it troublesome to attach and remove.

Structure of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention provides a structure in which a large number of dividing plates are provided at the bottom of the main body case, and a length capable of pressing down the adjacent dividing plates. It is formed into a U-shape in cross-section with elongated side plates on both sides, and a hole for a thumbscrew is provided on the top surface of the base end, and a hole for a thumb screw is provided on the top surface of the base end, and a hole is provided at the tip end on the frame at the rear bottom of the main body case. A configuration is adopted in which a protrusion that engages with a protruding engagement member is fixed and penetrates in the horizontal direction.

(Function) By employing the above configuration, the split plate holding tool first engages the protrusion located at the tip of the side plate with the engagement member provided on the bottom of the main body case, and then the protrusion located on the top surface of the base end. By tightening the screw through the hole, the adjacent portion of the dividing plate at the bottom of the main case is fixed.

(Example) Below are examples 1 to 5 that embody the present invention.
This will be explained using figures.

As shown in FIG. 5, the high-voltage lead-in multi-circuit switch 1 of this embodiment is installed upright on a sidewalk or the like, and has an opening/closing door 3 on the front side of a box-shaped main case 2.

As shown in FIGS. 1 and 4, a large number of dividing plates 4 are provided at the inner bottom of the main body case 2, and on the upper surface of the dividing plates 4, a metal dividing plate presser 5A,
5B are fixed to the frame 2a at the bottom of the main body case 2 at predetermined intervals, and the dividing plate 4 is formed so as not to come off.

As shown in FIG. 4, the divided plate pressers 5A and 5B are provided with three divided plate pressers 5A at the joints of the divided plates 4, and two divided plate pressers 5B at the joints of the divided plates 4, In addition, two or three electric wire covers 13 are provided in the side plates 7 of each dividing plate holding device 5A, for a total of seven, and three covers 12 are provided at the joints of the dividing plates 4, for a total of 15 in five rows. It is being In addition,
In this embodiment, ten dividing plates 4 are provided.

Then, the wire cover 13 or the cover 1 as appropriate.
2 is removed to allow the power cable, trunk cable, or branch cable to pass through, and cover 12 is removed to allow the trunk cable or branch cable to pass through.

Here, the divided plate pressers 5A and 5B will be explained.

There are two types of the divided plate pressers 5A and 5B: a divided plate presser 5A having a structure shown in FIG. 2, and a divided plate presser 5B shown in FIG. Therefore, first, the second
The divided plate presser 5A having the structure shown in the figure will be explained.

The proximal end 6 is formed to have a U-shaped cross section, and the lower surface is formed on both sides of the proximal end 6 to be parallel to the upper surface near the center, and slightly obliquely near the proximal end 6 and the distal end. A pseudo-trapezoidal and elongated side plate 7 is integrally formed, and a cylindrical protrusion 8 is fixed to the distal end of the side plate 7 so as to penetrate in the horizontal direction. Further, a circular hole 6a is provided on the upper surface of the base end portion 6, and a thumbscrew 1
0 is now inserted.

As shown in FIG. 1, the protrusion 8 is engaged with an engaging member 9 that is provided in an L-shape projecting from above toward the rear on the frame 2a at the rear bottom of the main body case 2. The thumbscrew 10 of the base end 6 is inserted into the frame 2 at the lower front side of the main body case 2 through the hole 6a on the top surface of the base end 6.
It is screwed and fixed to a fitting member 11 protruding from a.

As mentioned above, the split plate holder 5A has a cutout on the top surface from the base end 6 to the distal end, and three wire covers 13 are provided in that part. The cable is passed through.

Next, the divided plate presser 5B having the structure shown in FIG. 3 will be explained.

This split plate holder 5B has the same structure of the proximal end 6 and the structure of the protrusion 8 at the distal end as the split plate holder 5A having the structure shown in FIG. There is a point where there is no notch. In this way, the divided plate pressers 5A and 5B of this structure
can be used depending on whether a power cable is required or not, taking into consideration the effective use of the space inside the switch of this take-out section.

The functions and effects of the embodiment configured as described above will be explained.

First, as shown in FIG. 1, ten divided plates 4 are sequentially placed on the frame 2a at the bottom of the main body case 2 with their front and rear ends. Next, the left and right adjacent parts of the divided plate 4 are fixed using the divided plate pressers 5A and 5B as follows.

Regarding the fixing method, please refer to the split plate holder 5A, 5B.
Both are the same. That is, the split plate presser 5 is pressed against the engaging member 9 which is provided in an L-shape projecting from above to the rear on the frame 2a at the rear bottom of the main body case 2.
The protrusions 8 on the left and right sides of the tips of A and 5B are
Rotate the rear part of the engaging member 9 from above to engage it.
Next, the base end 6 is placed on the frame 2a at the lower front side of the main body case 2, and the thumbscrew 10 is fitted and tightened from above the base end 6 into the fitting member 11 on the frame 2a. The part 6 is fixed to the frame 2a.

In this way, the divided plate pressers 5A, 5 of this embodiment
In B, there is no need to tighten both the distal end and the proximal end with bolts in the limited space at the bottom of the main body case as in the conventional case. Therefore, it can be easily installed with one hand.

Split plate holder 5 installed as above
In A and 5B, the lower surface parallel to the upper surface near the center of the side plate 7 comes into contact with the dividing plate 4, and the adjacent parts of the dividing plate 4 are fixed by pressing from above.

The present invention is not limited to the above embodiments, but may be configured as follows.

(1) In the above embodiment, the L-shaped engaging member 9 has an inner surface formed at a right angle, but the inner surface is formed into an arc shape to correspond to the protrusion 8 at the tip of the split plate holder 5A, 5B. be able to. In that case, the engagement between the engagement member 9 and the protrusion 8 becomes even more reliable.

(2) In the above embodiment, the L-shaped engagement member 9 was formed into an L-shape from above toward the rear, but it can be formed into an L-shape from above toward the front. In this case, the split plate presser 5A,
The distal end portion of 5B is rotated downward from the front of the engaging member 9 to engage it.

Further, the engaging member 9 can also be formed in a shape other than the L-shape, for example, a plate shape provided with a circular hole.

Even with these shapes, the same effects as in the embodiments described above can be achieved.

Effects of the invention The multi-circuit switch split plate retainer of the present invention can be used with one hand by first engaging the protrusion at the tip with the L-shaped engagement member, and then tightening the base end with a thumbscrew. It has the excellent effect of being easy to install and fix.
