<p>PROBLEM TO BE SOLVED: To simplify an insulation protecting work, by molding a joint box into the box with a slender inner shape capable of storing a connection core bundle therein, and by making the joint box operable ups and downs, back and forth, right and left to store therein and fasten thereto easily the connection bundle. SOLUTION: Storing a connecting core bundle (A) in a transparent joint box in a box-cover opening state, its lower cables 8 are so bound that a binding band 10 and locking bars 5 do not escape therefrom. Then, providing an arbitrary number of hanging tools 14 and fastening portions in arbitrary outer- peripheral places of the joint box, the joint box is fastened to a construction material and a box cover 2 is closed to fix it on a box body 1 by locking a hook portion 6. Also, in the joint box, coupling the box body 1 to the box cover 2, a halved box is made operable, not only right and left when the body 1 and cover 2 are coupled to each other vertically, but also, ups and downs when the top surface of the body 1 is fastened to the construction material. Thereby, in each of the foregoing cases, the storing and fastening works of the connection core bundle A can be executed easily in a box-cover opening state.</p> |
