[0011]
Since both ends of the cable hanger ring H are hooked on the suspension line W, the cable hanger ring H is bent. The suspension hooking bent portions at both ends have similar shapes but are not the same, and are bent in opposite directions, and one has a deep hooking angle with respect to the suspension wire and the other is shallow.
[0012]
This takes into consideration the attachment and detachment to the suspension line W. At the time of attachment, the elastic leg H2 having the deepest engagement angle is first engaged with the suspension line W, and then it is engaged while resisting the elasticity of the steel wire. The elastic leg H3 having a shallower angle is hooked. A fixed position on the suspension wire W is held by the elasticity of the steel wire rod.
In addition, the elastic leg H2 with the deeper hook angle of the cable hanger ring H has a role of preventing the hanger ring from moving due to the sliding of the hanger ring from vibration due to wind pressure or the like on an inclined ground. ) To prevent the cable from moving and drooping due to a long-term natural phenomenon.
In addition, since the elastic legs H2 and H3 for hooking the hanging line W are bent in opposite directions, if one of the extending directions of the hanging line W covers the hanging line W from the right direction, The other is a hook from the left.
[0013]
A procedure for attaching the cable hanger ring H will be described with reference to FIGS.
First, the elastic leg H <b> 2 with the deeper hook angle of the cable hanger ring H is fitted into the support body 6 so as to be on the side of the deep and shallow identification protrusion 8 of the elastic leg. (Figure 3)
