<p>PURPOSE:To prevent completely a water leak by a method wherein a primary side sealing means and a secondary side sealing means are made to act and sealing means are made to deform to seal the connection part of a feeding cable in two stages. CONSTITUTION:A cylindrical body 11 is provided at a site, wherein a feeding cable is inserted, and the body 11 is provided with a primary side sealing means 12 and a secondary side sealing means 13. The feeding cable is inserted in between an elastic body 16, disc members 22 and a clamping body 17 of the means 12 and an elastic body 19 and a clamping body 20 of the means 13 and after that, bolts 18 and 21 are clasped and the bodies 17 and 20 are pressed. The bodies 16 and 19 are deformed by this pressing to full out in the diametral direction of the body 11, the cable is clamped and the periphery of the cable is sealed to seal the cable. Thereby, even if a large water pressure is applied to the body 11, water do no leaks and the cable can be used over a long period of time.</p> |
