<p>PROBLEM TO BE SOLVED: To make a spacer compact and raise work efficiency, by providing a holder with a cable holding clamp which can hold each conductor from inside the circle enveloping each conductor and a frame with a hinge part which enables it to be folded. SOLUTION: Cable holding clamps 3 hold cables, severally, and an I metal fitting 2 couples each clamp 3 with a frame 1, giving them a measure of freedom. In condition that a pin 5 is inserted into a hinge part 4, the spacer can be folded. However, pulling off a pin 5 at one end will let a stopper 7 suppressed by a built-in spring 6 thrust out, whereby frame becomes unable to fold. Accordingly, the spacer can be folded into half, and this can clamp the conductors each from inside the circle enveloping each conductor of a multiple conductor cable duct, so the transportation cost of the spacer can be reduced, and the work efficiency at work execution can be raised.</p> |
