Specific embodiment
Referring to FIG. 1 to FIG. 3, a kind of one embodiment of the hard composite insulator with proof mechanism of water of the utility model, packet
The insulator 1 being made of insulating bar and the several compounded rubber water-proof plates 12 being connected on the insulating bar is included, the insulating bar is by gold
The insulating layer 13 for belonging to plug 11 and its middle part surface forms, which is structure as a whole with compounded rubber water-proof plate 12；?
The top of the metal mandrel 11 is equipped with binding clip 2, is equipped with metal screw and fixture nut 3 in the bottom end of the metal mandrel 11.
The binding clip 2 is made of bottom plate 21, top plate 22 and clamping plate bolt 23 (screw rod and nut), the bottom surface of bottom plate 21
It is connect with the top of the metal mandrel 11；Top plate 22 is located at the upper surface of bottom plate 21, and the two is connected by clamping plate bolt 23；?
