<p><P>PROBLEM TO BE SOLVED: To avoid the problem of cable coming-off by enhancing handleability while suppressing manufacturing costs in a unit cable for indoor wiring in which a plurality of VVF cables are suspended in a joint box. <P>SOLUTION: Ten VVF cables 10 are divided into three sets, that is, a set of three cables, a set of three cables, and a set of four cables. The VVF cables 10 of each set are bound together by each binding band 13. A wire connection part 7 is stored in a joint box 2 while a binding band 14 is inserted into holes 6 for fixing a cable. Then, three cable bundles 11 are bound together by the binding band 14 so as to fasten them. By this, manufacturing costs are suppressed since it does not require molding by a thermosetting resin. Handleability is enhanced since the weight of the unit cable is reduced by the weight of a thermosetting resin. Moreover, the major-axis sides of all the VVF cables 10 are brought into contact with each binding band 13. Therefore, a frictional force between the VVF cables 10 and each binding band 13 is increased. Consequently, it avoids the problem of cable coming-off when the VVF cables 10 are pulled. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
