<p>PURPOSE: To surely obtain conduction and specified holding force and prevent an electric wire from being damaged more than necessary by providing parts of a pair of wedges which are brought into contact with the electric wire with cut through blades having a specified radius at an edge along the longitudinal direction of the electric wire. CONSTITUTION: An installation section 5 is installed on an electric pole and an installation section 4 is installed on an electric wire W through a special rope. A wedge section 10 is mounted on a specified holding place of the electric wire W through a bolt 11. Nextly, the wedge section 10 is inserted into a holding section 3 and is driven to a specified place. Then, cut through blades 16a, 16b break a coating of the electric wire W and thereby a clamp and a conductor W2 come to a continuity state and at the same time, the electric wire W is held with a specified holding force. Since a radius at an edge of the cut through blades is 0.1-0.5mm, there is no possibility that the electric wire W is damaged more than necessary. Due to this structure, the electric wire is prevented from being damaged and the electric wire can be held easily.</p> |
