Abstract
A composite post insulator. The main insulator that has solved at present adopts the screw to compress tightly usually, needs the instrument to adorn tightly, uses comparatively troublesome problem. The method is characterized in that: the wiring piece is in threaded connection with the core rod, a through hole (21) is formed in the wiring piece, a plurality of elastic sheets (211) are arranged on the upper end face of the core rod, a clamping groove (212) used for clamping a wire is formed between the elastic sheets, and the through hole is used for being in contact with the outer wall of the elastic sheet to draw in the clamping groove. The utility model provides a composite post insulator does not need the instrument can the wiring, and it is more convenient to install.
Description
Technical Field
The utility model relates to an electric power facility field, concretely relates to composite post insulator.
Background
Silicone rubber is an excellent electric power external insulation anti-pollution flashover material, has high insulation strength, hydrophobicity and hydrophobic migration, can greatly improve the pollution flashover voltage of an insulator by being attached to the surface of porcelain or glass of the insulator, and is called a composite insulator or a composite insulator in the industry.
The current insulator is usually compressed by screws, needs tools to be tightened, and is troublesome to use.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of background art, the utility model provides a composite post insulator has mainly solved present insulator and has adopted the screw to compress tightly usually, needs the instrument to adorn tightly, uses comparatively troublesome problem.
The utility model discloses a concrete implementation scheme does:
the utility model provides a composite post insulator, includes insulator body and wiring spare, the insulator body includes the outer chute boot that covers of plug and plug, wiring spare with plug threaded connection, be equipped with the through-hole on the wiring spare, the plug up end is equipped with a plurality of shell fragments, and is a plurality of form the tight groove of clamp that is used for pressing from both sides tight wire between the shell fragment, the through-hole be used for with the contact of shell fragment outer wall is in order to draw in press from both sides tight groove.
The cross section of the wiring piece is circular.
And a thread part for being in threaded connection with the core rod is arranged on the inner side of the side wall of the wiring piece.
The shell fragment is equipped with 2 at least.
The number of the elastic pieces is four.
The umbrella cover comprises a large umbrella skirt with a large diameter and a small umbrella skirt with a small diameter, and the large umbrella skirt and the small umbrella skirt are arranged in a staggered mode along the axial direction of the core rod.
