PROBLEM TO BE SOLVED: To provide a laughter prevention type anchor clamp capable of preventing occurence of an excessive stress on a steel core wire in compressing an aluminium sleeve.SOLUTION: The laughter prevention type anchor clamp 1 comprises: a steel clamp 2 having a steel sleeve 3 and a shackle portion 4, an aluminium clamp 5 having an aluminium sleeve 6 and a jumper line connection 7, and a pair of halved collars 8. The steel sleeve 3 receives a steel core wire W1 exposed to one end of an electric wire W to be integrally compressed therewith. The outer periphery near an end of the steel sleeve 3 has an annular groove 31 with a slope face 32. The aluminium sleeve 5 is extrapolated over the steel sleeve 3 and the one end of the electric wire W to be compression connected thereto. When the pair of halved collars 8 with a slope face 84 are mounted to fit to the annular groove 31 of the steel sleeve 3 and the steel sleeve 6 is compressed, the slope face 84 is slid with the slope face 32 and the steel clamp 5 is pushed in a direction of the electric wire W to reduce tensile stress on the steel core wire W1. |
