DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a wiring device for facilitating the drawing of electric wires into a ceiling, a hollow wall, a floor or the like during wiring work.

[0002]

Conventionally, in wiring work on ceilings, hollow walls, under floors, etc. in which workers cannot enter, inspections must be performed in order to pull out the inserted wires from the small holes for inserting wires to the inspection opening. An antenna-shaped hook rod was inserted through the mouth, and the hook was used to hook the electric wire to reduce the hook rod and pull it out. At that time, if the wire is hooked on the end of the wire, the wire is easily detached from the hook. In order to pull the wire so that it does not come off from the hook, it is necessary to feed a considerable length of electric wire so that the wire is hooked at an appropriate place. Then, the electric wire breaks at the hooked position, so that when one electric wire is hooked, it becomes two wires, and two wires are pulled together, so that a considerable weight is pulled. If the wire increased in length with the hook rod extending to about 10 m, and the wire fed in a long length was bent and overlapped or had a spiral shape over a wide area, the pulling out work was not easy. The present invention has been made in view of the above circumstances, and provides a wiring device that allows an electric wire to be easily pulled from a distal end.

[0003]

According to the present invention, there is provided a wire-connecting device, wherein a large annular portion is provided by an expanding member and a hooking hole for hooking a wire is provided below the large annular portion. A sliding body is provided. In addition, a stopper is provided on the annular portion for fixing the position of the cylindrical body.

[0004]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a case where an electric wire is connected to the wiring device of the present invention. The expanding member is made of a material such as a wire, a shape memory alloy, a resin, or the like, which can easily maintain its shape without being bent when it is formed into a ring shape with a wire. The linear expanding member 2 is folded and inserted into the cylindrical body 1 to form a large annular portion 3 upward. The tubular body 1 has an inner diameter that allows the annular portion 3 to slide up and down easily. Next, the above-folded expanding member 2 is inserted into the cylindrical stopper 4. Therefore, the stopper 4 is located below the cylinder 1. The stopper 4 has an inner diameter close to the outer diameter of the expanding member 2 which is folded and overlapped, and is preferably made of a material having a high frictional resistance, such as natural rubber, synthetic rubber or sponge.
Alternatively, a material having a large frictional resistance may be used only for the inner surface. In this embodiment, the outer shape of the stopper 4 is cylindrical, but the shape is not limited. Below the expanding member 2, one is folded up and overlapped with the other one end, and the overlapped portion is fixed with the sleeve 5 to form a hooking hole 6 for hooking the electric wire 7. When the electric wire 7 is used, the hook hole 6
And connect it by twisting. Although the length of the cylindrical body 1 is not limited, it is preferable to use a cylindrical body having a size capable of pushing up the heat insulating material on the ceiling on which the heat insulating material is laid. When the heat insulating material is pushed up by the cylindrical body 1, the annular portion 3 is located above the heat insulating material. The cylindrical body 1 in the case where the heat insulating material is not laid may have a size that can be easily inserted into the small hole 8 and that can easily maintain the upright state.

FIG. 2 is a perspective view exemplifying a use method when wiring is performed on a ceiling. First, the cylindrical body 1 is slid above the annular portion 3 to reduce the annular portion 3 and inserted into the small hole 8 provided on the ceiling. (The small holes are of a size sufficient to insert the cylinder 1).
Is pushed up from below to expand and form a large annular portion 3 above the cylindrical body 1. The cylinder 1 is stopped at a position where it is released by the restoring force of the annular portion 3 inside. However, in order to stabilize against external shocks, a stopper 4 is provided and moved to the lower end of the cylinder 1. deep. When the cylinder 1 is inserted into the small hole 8, if the small hole 8 is larger than the cylinder 1,
When the adhesive tape 11 is wrapped around and the outer diameter is adjusted and inserted into the honey, the upright state of the cylindrical body 1 inserted into the ceiling becomes stable, so that the upright state of the expanded annular portion 3 is also stable. It is easy to catch and work easily. Next, an antenna-shaped hooking rod 10 is inserted from the inspection opening 9 while extending the hook, and the hook 3 at the tip is used to hook the annular portion 3. Since the annular portion 3 is greatly expanded to be easily hooked, the expanding member 2 is pulled downward from the cylindrical body 1 inserted through the small hole 8 when the annular portion 3 is hooked on the annular portion 3 so that the annular portion 3 is expanded. When retracted, the hook of the hook bar 10 is fixed to the annular portion 3 and does not come off. At this time, if the stopper 4 is moved to the lower end of the cylindrical body 1, the stopper 4 can be fixed so as not to slide down against an external shock. Therefore, the electric wire 7 can be smoothly pulled out to the inspection port 9 in a single wire state while the antenna-shaped hook rod 10 is reduced.

[0007] Since the ceiling, hollow walls, under the floor and the like are dark, the inspection opening 9
It is necessary to check the annular portion 3 while illuminating the flashlight with a flashlight, and insert the hook bar 10. Therefore, in order to facilitate the work, the workability is improved by forming the tubular body 1 itself from a luminescent material, or by winding or applying a luminescent material around at least a part of the tubular body 1 or the annular portion 3. . Also,
The stopper 4 may be formed of a light emitting material. In this case, if the stopper 4 can be confirmed, the cylindrical body 1 and the annular portion 3 thereabove.
Can be determined, a light emitting material may be provided as a mark on a part of the cylindrical body 1 and the mark and the expanding direction of the annular portion 3 may be matched.

In the above embodiment, the cylinder 1 and the stopper 4
Is illustrated as a separate body, but a stopper may be integrally connected to the upper end or lower end of the cylindrical body 1. Alternatively, a material having high frictional resistance may be provided on a part of the inner surface of the cylindrical body 1. The case where the cylinder 1 and the stopper 4 are separate bodies is convenient because only the cylinder 1 can be easily slid up and down when finely adjusting the size of the annular portion 3. The one in which the cylinder 1 and the stopper 4 are integrated is convenient when fine adjustment of the annular portion 3 is not required since only the cylinder 1 needs to be slid up and down although there is some frictional resistance.

[0009]

According to the present invention, since the tubular member is provided outside the expanding member as described above, the wire passing device does not bend when inserted from a small hole and can be easily operated. The annular part is expanded or contracted by a simple operation of sliding the cylinder up and down to easily and securely attach and detach the hook to and from the hook, so that the electric wire can be smoothly guided to the inspection port. . By providing the stopper, the cylindrical body can be fixed at an arbitrary position, so that the expanded and contracted state of the annular portion can be reliably maintained. The effect obtained by the above-described configuration significantly enhances the working efficiency and is useful.
