<p>PROBLEM TO BE SOLVED: To assemble a very light and easily treated cable holding unit, by using a standard-length cable protecting pipe having a socket portion, the similar one having an insertion portion to be connected watertight with the socket portion and a rectangular parallelopiped-form foaming material in whose axial center side portion the cable protecting pipe is provided in the state of its insertion portion being protruded. SOLUTION: Separated rectangular parallelopiped-form foaming materials 2-2a, 2-2b and a rubber ring-sealed type cable protecting pipes 3A-1, etc., are assembled to form a cable holding unit. The connection of the cable protecting pipes is performed by their socket portion 3A-1 and insertion portion 3A-3. The upper and lower rectangular parallelopiped-form portions opposed to the socket portion 3A-1 are formed out of foaming materials 2A-1a, 2A-1b. The upper and lower rectangular parallelopiped-form portions opposed to a straight pipe portion 3A-2 are formed out of foaming materials 2-2a, 2-2b. A watertight rubber ring 4 is attached to the insertion portion 3A-3. These cable protecting units are connected with each other in a long-length way to obtain a very light water-proof cable holder.</p> |
