More particularly, the present invention relates to a method of connecting a power cable protective pipe, and more particularly, to a method of connecting a power cable protective pipe of steel material, cutting the end of the power cable protective pipe to the size for fastening the power cable protective pipe, The present invention relates to a method of connecting a power cable protective pipe with an improved process so as to enable coupling between power cable protective pipes even through a simple fitting connection without machining a cable protective pipe end.

Generally, the power cable protection pipe is to prevent the power cable from being exposed to the outside by allowing the power cable to be accommodated therein.

These power cable shields should be configured to respond differently to site installation conditions.

Therefore, conventionally, it is necessary to cut the power cable protection pipe to the length of the power cable, and then connect the cut power cable protection pipe in accordance with the installation condition of the power cable.

In this case, as shown in FIG. 1, the power cable protection pipes are connected through a coupling, but the conventional coupling connects a pair of power cable protection pipes with a screw connection.

That is, conventionally, in order to bind the power cable protective pipe to the coupling, the length of the power cable and the power cable protective pipe 10 are not matched.

After the end of the cable protective pipe 110 is machined into the thread 11a in accordance with the coupling, the cable protective tubes 11 are fastened to each other through the coupling 12 provided with the screw 12a.

In this case, since it is necessary to perform the work of forming the thread in the field after cutting the end of the power cable protection pipe every time, it is complicated and difficult to connect the power cable protection pipe conventionally.

Therefore, there is a problem that the field workability is poor and labor costs are increased.

Further, after the other binding member having the annular fitting portion is positioned between the other side of the coupling and the protective tube, the exposed portion of the other binding member is pressed by the binding jig, So as to be forced into the protection tube.

The fitting portion of the coupling member may include a plurality of slits for allowing the reduced space when the outer diameter is forcibly reduced and a plurality of slits provided between the adjacent slits for increasing the fixing force between the slits and the outer surface of the protection tube Wherein the fitting portion of the fitting portion is deformed in the process of forcing the fitting portion of the binding member between the coupling and the protection tube so that the binding operation by the binding member is smoothly performed .

The portion of the coupling and the fitting portion of the coupling member facing each other has a tapered shape so that in the process of forcing the fitting portion of the coupling member between the coupling and the protection tube in a forced manner, Smooth insertion is enabled, so that the binding operation by the binding member can be performed smoothly.

According to an embodiment of the present invention, there is an advantage that, in connecting the power cable protective pipes, the protective pipes can be easily coupled to the coupling without machining the end of the protective pipe for coupling with the coupling.

By virtue of these advantages, the process of bonding the power cable protective pipe is simplified, and the work efficiency is increased, thereby reducing labor costs.
