A cable gripping tool 8 shown in FIG. 9 is constituted by a pair of gripping plates 10 having a curved portion 9 curved in a shape substantially matching the outer peripheral surface of the cable 2 at the center, and the curved portions 9 of both gripping plates 10. The cable 2 is centered by gripping it in between.
[0005]
[Problems to be solved by the invention]
Incidentally, in the case of the cable gripping tools 1 and 5 shown in FIGS. 7 and 8, since the cable 2 is gripped by adjusting the movement amounts of the plurality of movable members 4 and 6, it is difficult to center the cable 2. Since it is necessary to secure a space for operating the movable members 4 and 6 at a plurality of locations around the cable gripping tools 1 and 5, it is easy to cause an upward operation and interference with surrounding structures, and all the movable members are movable. There was a problem that it was difficult to ensure good operability for the members 4 and 6. In view of the above problem, it is conceivable to install a mechanism for operating all the movable members 4 and 6 simultaneously by operating only one member. However, the cable gripping tools 1 and 5 are increased in size and cost. In addition, when applied to an aerial cable closure or the like, the increase in the weight of the cable gripping tools 1 and 5 may cause the cable 2 to hang down, and thus the problem cannot be fundamentally solved.
In the case of the cable gripping tool 8 shown in FIG. 9, it is necessary to prepare many types of gripping plates 10 corresponding to the diameter and cross-sectional shape of the cable 2, which is disadvantageous in terms of cost.
