Next, the operation will be described. The wiring of this embodiment,
As shown in FIG. 1, the pulling-in device A for piping or the like is constructed such that, after inserting the fitting portion 10 of the insulator 1 into the mounting hole 50 formed in the outer case 5 of the high-voltage resistant device or the like, the insulator stopper 13 and the tightening band. 17 and 17 are inserted into the fitting portion 10 in this order, and first, the tightening band 17 is tightened and firmly fixed to the fitting portion 10. still,
In this case, the packing 19 a is sandwiched between the outer case 5 and the flange portion 11, and the mounting hole 50 of the outer case 5 is attached.
A sealing material is provided in advance. Then, after fixing the tightening band 17, the small screw 15 of the insulator stopper 13 is clamped through the flat washer 19b to thereby secure the outer case 5 with the insulator stopper 13 and the flange portion 11 of the insulator. Let Next, the high-voltage wire 51 is fitted with the female screw portion 3 and the packing 4 which are directed toward the wire entry side, and is inserted into the lead-in hole 22 formed in the insulator 1 from the outside of the outer case 5, so that wiring inside the device is required. After pulling in the length, the other female screw portion 3 and the packing 4 are attached from the wire entry side of the wiring, and both sides of the insulator 1 are sufficiently tightened. In this case, the drawing hole 2
Since 2 has no step, the wiring can be pulled in smoothly. Then, the packing 4 is compressed by the taper surface 26 provided at the tip of the male screw 25 and the taper surface 31 of the female thread 3 by the tightening force of the female screw portion 3, whereby the packing 4 is compressed and the wiring 51 is fixed. With wiring 5
The gap between 1 and the drawing hole 22 is sealed. Therefore,
The wiring 51 is drawn into the apparatus while maintaining a sufficient insulation state, and the drawn-in portion is sufficiently sealed by the packings 4 and 4 on both sides to shut off the inside of the apparatus from the outside.

As described above, the wiring of this embodiment,
In the drawing device A such as a pipe, the wiring drawn into the device can be easily fixed and the drawn part can be sealed inside and outside the device. Therefore, the wiring work is simplified, and it is possible to sufficiently block the outside without filling the insulating material or the like. Further, the length of the inserted wiring can be arbitrarily adjusted only by loosening the female screw portion 3. For this reason, it is also advantageous to use it in an experimental device or the like that frequently changes wiring. Also, since connection terminals etc. are not required in the middle of wiring,
The work is easy, and since there is no connecting portion, there is no physicochemical influence due to the corrosion phenomenon of the connecting portion, so that the resistance value does not fluctuate. Further, the specific resistance unique to the wiring can be ideally utilized without considering the influence of the interface resistance at the lead-in portion at all. Further, by selecting the packing having the diameter suitable for the wiring, it is possible to arbitrarily draw in the wiring having various outer diameters.

Further, the insulator 1 has the tightening band 17 in the fitting portion 1
It can be easily fixed by simply tightening it to 0 and tightening the small screw 15 of the insulator clasp 13. Also, it can be easily replaced or removed simply by loosening the tightening band.
Further, by changing the position of the tightening band, the thickness of the mounting wall surface can be adequately accommodated, and the insulator 1 does not require an annular groove or the like, which facilitates the manufacture.

As described above, in the device for retracting wiring or piping according to claim 1 of the present invention, the retracted wiring or the like can be easily fixed and the insertion portion can be sealed. Therefore, the wiring work is simplified, and it is possible to sufficiently block the outside without filling the insulating material or the like. or,
The length of the drawn wiring and piping can be adjusted simply by loosening the female thread. For this reason, it is also advantageous to use it for an experimental device or the like that frequently changes the wiring. Further, since the connection terminal and the like are not required in the middle of the wiring, the work becomes easy. Further, since there is no connecting portion, there is no physicochemical influence due to the corrosion phenomenon of the connecting portion, so that the resistance value does not fluctuate. Besides, it is possible to ideally utilize the specific resistance unique to the wiring without considering the influence of the interface resistance in the lead-in portion at all. Further, by selecting packing having a diameter suitable for the wiring or piping, it is possible to obtain the effect that wiring or piping having various outer diameters can be arbitrarily drawn. Moreover, in this retractor, the insulator can be easily attached to and detached from the device.
Further, since the insulator does not need to be processed with an annular groove or the like, it is easy to manufacture, and it is possible to sufficiently cope with the thickness of the mounting wall surface. Further, in the retracting device according to the second aspect, there is an effect that even if the insulator is formed of an adhesive such as tetrafluoroethylene resin that is difficult to use, it can be effectively sealed by the sealing material. can get.
