Description

[Detailed Description of the Invention] [Background and Purpose of the Invention] The present invention relates to a cable suspension device useful for suspending the upper end of a vertical trunk cable in an apartment, building, etc.

In a device that suspends multiple cables at once, if the cable lengths are uneven, an imbalance will occur in the load distribution of each cable, and the entire load of the multiple cables will be suspended on a part of the suspension base. This causes a problem with the safety of the suspension device.

However, conventional suspension devices do not have a mechanism for correcting such uneven cable lengths, making it difficult to adjust the cable lengths on site.

Conventionally, a compression sleeve with an integral bolt is attached and fastened to the exposed conductor terminal by peeling off the insulation at the cable end, and the bolt is passed through the suspension base from bottom to top. A hanging device has been proposed in which a nut is screwed onto the bolt that protrudes upward (for example, Japanese Utility Model Application No. 153830/1983).
In such a device, by rotating the nut, the compression sleeve can be moved up and down with respect to the suspension base, making it possible to adjust the cable length.

However, with this device, the nut is located above the suspension base and approaches the ceiling, which serves as the suspension wall of the device, making it extremely difficult to operate the nut.
It was not suitable for adjusting the cable length.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a cable hanging device with a cable length adjustment mechanism that can easily adjust the cable length even if the cable length is uneven. There is.

[Summary of the idea]

As shown in the attached drawing, the cable hanging device with a cable length adjustment mechanism of the present invention is constructed by drilling a screw hole 7a vertically penetrating a hanging base 7 suspended from a hanging fitting 1, and A tubular adjusting screw 5 having an inner diameter larger than the outer diameter of the cable 6 is screwed into the screw hole 7a from bottom to top, and the cable 6 is inserted into the tubular adjusting screw 5 from bottom to top to insulate the cable 6. The conductor terminal 6a and the conductor terminal 6b exposed therefrom are projected above the adjustment screw 5, and the insulating ring 4 is placed on the upper end of the adjustment screw 5 so as to cover the periphery of the insulator terminal 6a. , the lower end of the compression sleeve 3 compressed and fastened to the conductor terminal 6b is brought into contact with the insulating ring 4, and the compression sleeve 3 is further covered with an insulating cover 2,
In addition, the cable length can be adjusted by rotating the adjusting screw 5 from below the suspension stand.

〔Example〕

1 and 2 are a plan view and a partially sectional front view showing a preferred embodiment in which three cables are suspended at once.

A rod-shaped metal fitting is vertically attached to the hanging metal fitting 1 having an eye structure, and a hanging stand 7 is suspended at the center of the lower end of the metal fitting. It has a screw hole 7a drilled therein. In this embodiment, three screw holes 7a are provided at equal intervals on the same circumferential track, and the adjusting screw 5 is screwed into each of them.

The adjusting screw 5 is a tubular member having an inner diameter larger than the outer diameter of the cable 6, and has a thread groove carved on its outer peripheral surface. This adjustment screw 5 is screwed into the screw hole 7a of the suspension base 7 from bottom to top, and
It is designed so that it can be rotated from the bottom.

At the end of the cable 6, an insulator terminal 6a is stripped back to form an exposed conductor terminal 6b, and these are inserted into the adjusting screw 5 from the bottom to the top. It extends upward and protrudes. Then, the insulating ring 4 made of fiber reinforced plastic (FRP) or the like is placed on the upper end of the adjusting screw 5 so as to cover the upwardly projecting insulator terminal 6a. Then, the compression sleeve 3 is covered and fastened to the conductor terminal 6b, and the lower end of the sleeve 6b is brought into contact with the insulating ring 4. It is supported on the adjusting screw 5 via the adjusting screw 5.

If the protruding lengths of the cables 6 from the suspension base 7 are uneven, please adjust the length of each cable 6 by rotating the adjustment screw 5 protruding below the suspension base 7.
By adjusting the vertical movement of the compression sleeve 3 connected via the insulating ring 4,
And the cable 6 integrated with this through the conductor terminal 6b is moved up and down, and as a result, the cable 6
The length of the cables 6 protruding from the suspension base 7 is adjusted so that the loads of the cables 6 received by the adjustment screws 5 are equalized.

[Effect of idea]

As is clear from the above embodiments, according to the present invention, since the adjustment screw is operated from the bottom of the suspension stand, even if there is an uneven cable length, it can be easily corrected. The intended purpose of providing a cable suspension device with a cable length adjustment mechanism is achieved.

In addition, according to the cable hanging device of the present invention,
The following effects can also be achieved.

That is, the cable portion whose surface is covered with the insulator 6a is inserted through the tubular adjusting screw 5, and the exposed conductor terminal is projected above the adjusting screw.
Furthermore, since the adjusting screw 5 is connected to the compression sleeve 3 via the insulating ring 4, there is no need to perform any insulation treatment on the adjusting screw 5.
It is only necessary to insulate only the compression sleeve that is fastened to the terminal of the conductor, which simplifies a series of insulating processes and contributes to the simplification of the structure.

Furthermore, since the compression sleeve is fastened to the conductor terminal 6b protruding on the suspension stand 7 and its lower end is supported on the adjustment screw 5 via the insulating ring 4, the sleeve size can be reduced. The entire device can be made compact, and cables can be hung advantageously in places where space is limited.
