[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk-type unit cable used for indoor wiring work or the like.

[0002]

2. Description of the Related Art Conventionally, in indoor wiring work and the like, in order to carry out work efficiently, as shown in FIG. A disk-type unit cable 4 is used in which the connection portions of these cables 2 are formed and housed in a disk-shaped storage box 3 made of synthetic resin, and the other end is drawn radially from the outer periphery of the disk-shaped storage box 3.

[0003] The disk-shaped storage box 3 of the disk-shaped unit cable 4 stores a connection portion of a plurality of cables 2 and is molded with a molding resin such as vinyl. A mounting hole 5 for a structure is formed in the center.

When the disk unit cable 4 having such a structure is attached to a concrete ceiling, as shown in FIG. 8, an embedded bolt 7 previously embedded in a concrete ceiling 6 is passed through the mounting hole 5 and then bolted. To fix it to the ceiling.

On the other hand, when mounting on a wooden ceiling, as shown in FIG. 9, a mounting plate 9 having a bolt through hole 8 formed in the center is prepared. A method of fixing and fixing the mounting plate 9 to the wooden ceiling 11 with a wood screw 12 as shown in FIG. 10 or a strip-shaped mounting bracket 13 longer than the diameter of the disk-shaped storage box 3 as shown in FIG. And this mounting bracket 1
3 is fixed to the disk-shaped storage box 3 with bolts 14.
As shown in FIG. 2, a method of fixing the mounting bracket 13 to the wooden ceiling 11 with the wood screws 12 is implemented.

[0006]

[Problem to be solved by the invention] However, wooden ceiling 1
In the method of fixing using the dedicated mounting plate 9 or the mounting bracket 13 as in the case of fixing the mounting plate 1, the mounting plate 9 or the mounting bracket 13 must be prepared in advance, which increases the cost. Moreover, there is a problem that the construction time is lengthened by the amount of work to be attached to the mounting plate 9 or the mounting bracket 13, and the efficiency is low.

[0007] The present invention has been made in view of such problems of the prior art, and the object thereof is to efficiently and inexpensively construct a structure regardless of the type of the structure. An object of the present invention is to provide a disk-type unit cable that can be fixed.

[0008]

In order to achieve the above object, a disk unit cable according to the present invention is provided with a plurality of cables in a disk type storage box having a mounting hole for a structure formed in the center. In a disk unit cable in which a connection part having one end connected in common is housed and the other end is drawn radially from the outer periphery of the disk type storage box, an outer peripheral edge of the disk type storage box is provided on the upper and lower surfaces of the disk type storage box. The mounting portion having a mounting hole for mounting to a structure is formed so that the mounting position on the upper surface and the mounting position on the lower surface are alternately arranged so as to protrude from the structure.

[0009]

According to the above means, when the structure is a wooden ceiling,
A wooden screw is passed through the mounting hole of the mounting part provided on the upper surface or lower surface of the disk-shaped storage box, and is fixed to the wooden ceiling.

When the structure is a concrete ceiling, bolts are fixed through mounting holes in the center of the disk-shaped storage box. For this reason, a dedicated mounting bracket or the like is not required for the wooden ceiling, and the wooden ceiling can be fixed to the structure efficiently and at a low cost regardless of the type of the structure.

[0011]

Embodiments of the present invention will be described below. 1 to 3 show an embodiment of a disc unit cable according to the present invention. FIG. 1 is a plan view of the disc unit cable, FIG. 2 is a perspective view, and FIG. FIG.

The disk unit cable 4 of the present embodiment is
A plurality of sets of a plurality of cables 2 in which one end of a conductor is crimped and connected in common by a ring sleeve 1 are formed.
Is stored in a disk-shaped storage box 3 made of synthetic resin, and the other end is drawn radially from the outer periphery of the disk-shaped storage box 3. After being stored, it is molded with a molding resin such as vinyl. In the center, there is a mounting hole 5 for the structure.
Are formed.

Further, on the lower surface of the disc-shaped storage box 3, three mounting portions 17 provided with mounting holes 16 for a structure are formed at regular intervals so as to protrude from the outer peripheral edge. Also, three mounting portions 19 provided with mounting holes 18 for the structure are provided on the upper surface of the disk-shaped storage box 3 at equal intervals protruding from the outer peripheral edge, and are mounted on the lower surface of the disk-shaped storage box 3. The mounting portion 17 and the mounting portion 19 mounted on the upper surface of the disk-shaped storage box 3 are alternately arranged so that one of them does not interfere with a screwing operation for turning a mounting screw fitted into the mounting holes 16 and 18. Has become.

FIG. 4 is an exploded perspective view of the disk-shaped storage box 3, which is composed of an upper housing 30 and a lower housing 31. The housing 30 is covered, and the center hole 33 of the upper housing 30 and the upper end of the cylinder 32 erected at the center of the lower housing 31 are joined so as to fit together, and are engaged by the engagement claws 34 and 35. Thereafter, molding is performed as shown in FIG.

Attachment section 17 for attachment to a structure
Projecting from the outer peripheral edge of the lower housing 31 to be integral with the lower housing 31, and the mounting portion 19 projecting from the outer peripheral edge of the upper housing 30
Are formed integrally with each other.

When the disk unit cable 4 constructed as described above is fixed to the wooden ceiling, the mounting portion 17 formed on the lower surface of the disk type storage box 3 or the mounting portion formed on the upper surface of the disk type storage box 3 is used. It is fixed to the structure using one of the attachment portions of the portion 19. In this case, FIG.
As shown in (a) and (b), in a symmetrical house, unit cables 4 of the same specification are used, and in one house, a mounting portion 17 formed on the lower surface of the disk-shaped storage box 3 is used. In the floor plan on the other side, it is fixed by using the mounting portion 19 formed on the upper surface of the disk-shaped storage box 3. Therefore, when the disk-type unit cable 4 is fixed to the wooden ceiling by using the mounting portion 17 formed on the lower surface of the disk-type storage box 3, as shown in FIG. Mounting hole 16 of mounting part 17
Through a wood screw 12 and fixed to the wooden ceiling 11.

[0017] Therefore, a dedicated mounting bracket or the like is not required even when attached to the wooden ceiling 11, so that it can be efficiently and inexpensively fixed to a structure regardless of the type of the structure. When the structure is a concrete ceiling, bolts are fixed to the mounting holes 5 at the center of the disc-shaped storage box 3 as in the conventional case. As described above, according to the present embodiment, it is not necessary to prepare two types of unit cables for a symmetric layout, which is economical.

[0018]

[Effects of the Invention] Since the present invention is configured as described above, according to the present invention, a mounting portion having a mounting hole protruding from the outer peripheral edge and provided with a mounting hole to a structure is provided on the upper surface and the lower surface of the disk-shaped storage box. Since the mounting position on the upper surface and the mounting position on the lower surface are formed alternately, the structure can be efficiently and inexpensively fixed to the structure regardless of the type of the structure.
