LINEAR MATERIAL CONNECTING METAL FITTING

PROBLEM TO BE SOLVED: To improve workability and to reliably connect linear materials such as a steel wire with strong force by providing a pair of linear material sandwiching tools for fastening two linear materials with the force corresponding to the rupture torque of a pin tail. SOLUTION: A pressing-down member 4 and a receiving member 3 are fitted in order in the shaft part of a bolt 1, and a nut 2 is threadedly engaged. The respective end parts of linear materials 5, 5 to be connected between both side pressing-down parts 4b, 4b of the receiving member 3 are mutually inserted from the inverse direction. An inner sleeve of a nut runner is fitted in a pin tail 1c, and an outer sleeve is fitted in the nut 2, respectively, and the nut 2 is rotated until the pin tail 1c ruptures to fasten both linear materials 5, 5. In this case, a projecting strip formed in the pressing-down parts 4b of the pressing-down member 4 bites in the linear materials 5 to enable the firm connection. Even if a connecting metal fitting inclines since tensile force is applied to the connected two linear materials 5, 5, a stress concentration on the part of the opening edge can be avoided so as to prevent rupture.
