The present invention relates to a fastening structure of a dead end clamp, and more particularly to a fastening structure of a dead end clamp to be mounted by rotating the clamp to hold the power line to the suspension insulator connected to the pole of the pole according to the situation. It is about.

In general, the suspension insulator is an electric apparatus installed in an ultra high voltage transmission line, an extra high voltage distribution line, a tram line, a low voltage distribution processing line, and so on to insulate and prevent the wire from dropping, while maintaining the insulation.

In other words, the suspension insulator must support a wire such as a special high-voltage wire so as not to be separated, as well as having an insulating property, and thus requires good insulation with high tensile strength.

In addition, although the conventional suspension insulator uses a magnetic material as an insulator, when the magnetic material is used, there is a problem in that its weight is heavy due to the characteristics of the magnetic material, and it is easily broken by mechanical and electrical shocks during installation and repair work.

The support spring is inserted through the through-hole so that the coupling ball is seated on the coupling recess integrally formed on one side, and the coupling ball is seated on the coupling recess to be separated from the coupling space portion. The coupling ball can rotate within the coupling recess while supporting the coupling ball toward the coupling recess. Characterized in that the installation to.

In addition, in the structure in which the suspension insulator connected to the complete pole of the pole and the clamp for holding the power line is fastened, the coupling body is integrally formed at one end of the reference shaft core constituting the suspension insulator, and the combination is open at the top. The upper opening portion and the front opening portion are formed in the front opening portion has a structure in which a coupling space portion formed therein a coupling recess formed on the inner front surface and a through hole penetrating the bottom surface, the clamp is a coupling recess portion through the coupling space portion The support ball is inserted through the through hole so that the coupling ball is integrated into one side of the elliptical cross-section seated on the one side, so that the coupling ball is seated in the coupling recess so as not to be separated from the coupling space portion to the outside. The coupling ball is rotatably installed in the coupling recess while supporting the coupling recess. It shall be.
