The utility model provides an insulator string hanging point connection structure. The insulator string hanging point connection structure includes an electric tower cross-bar and an insulator string which is hung on the electric tower cross-bar; a hanging plate is fixed to the lower end of the electric tower cross-bar; the hanging plate and the insulator are connected with each other through a telescopic assembly; the telescopic assembly comprises an upper connecting pipe and a lower connecting pipe; an extendable steel wire rope is arranged in the upper connecting pipe; the lower end of the steel wire rope is fixedly connected in the lower connecting pipe; the upper end of the upper connecting pipe is hinged to the hanging plate; and the lower connecting pipe is hinged to the insulator string. The insulator string hanging point connection structure of the utility model is simple in structure. With the insulator string hanging point connection structure of the utility model adopted, the steel wire rope can be stretched through an elastic force in a strong wind environment, so that buffering can be realized, and therefore, collision of connecting parts between the hanging plate and the insulator string can be avoided, and fracture of the hanging plate can be prevented.
