However, the existing suspension type composite insulator has the following defects: 1. the sealing performance of the composite material and the upper metal connecting piece and the lower metal connecting piece is poor, rainwater and the like easily enter the core rod from the space between the sheath and the upper metal connecting piece and the lower metal connecting piece, and the insulating performance is influenced; 2. the composite material has no elasticity, the connecting strength of the sleeve, the upper metal connecting piece and the lower metal connecting piece is low, the sheath is easily separated from the upper metal connecting piece or the lower metal connecting piece, and the service life of the insulator is shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a suspension type composite insulator that insulating properties is good, long service life, corrosion resistance are good, be difficult to peck by birds.
In order to solve the above problem, the utility model discloses suspension type composite insulator adopts's technical scheme does: including the plug, have cable stiff end and last adapter sleeve last metal connecting piece, have adapter sleeve down and hang lower metal connecting piece, full skirt and the sheath of stiff end, insert respectively at the both ends of plug go up in adapter sleeve and the adapter sleeve down, be close to plug one side go up adapter sleeve's radial lateral surface and be provided with annular groove on, be close to plug one side adapter sleeve's radial lateral surface is provided with annular groove down.
The additional technical characteristics are as follows:
water-swelling adhesive tapes are respectively arranged in the upper annular groove and the lower annular groove;
the cross-sectional width of meeting water inflation adhesive tape is less than go up annular groove and the degree of depth of annular groove down, the cross-section of meeting water inflation adhesive tape is "U" style of calligraphy.
Compared with the prior art, the utility model provides a suspension type composite insulator has following advantage: one of the characteristics is that the umbrella comprises a core rod, an upper metal connecting piece with a cable fixing end and an upper connecting sleeve, a lower metal connecting piece with a lower connecting sleeve and a hanging fixing end, an umbrella skirt and a sheath, wherein two ends of the core rod are respectively inserted into the upper connecting sleeve and the lower connecting sleeve, an upper annular groove is arranged on the radial outer side surface of the upper connecting sleeve close to one side of the core rod, a lower annular groove is arranged on the radial outer side surface of the lower connecting sleeve close to one side of the core rod, the umbrella skirt and the sheath are made of polycarbonate materials with high strength and corrosion resistance, convex rings are formed on the inner sides of the sheath corresponding to the upper annular groove and the lower annular groove and clamped in the upper annular groove and the lower annular groove, the sheath is more firmly connected with the upper metal connecting piece and the lower metal connecting piece, and the sheath and the umbrella skirt cannot be separated from the upper metal connecting piece and the lower metal connecting piece when the sheath or the umbrella skirt is subjected to external impact, the convex rings are clamped in the upper annular groove and the lower annular groove, and rainwater is prevented from entering the core rod; secondly, because the water-swelling adhesive tapes are respectively arranged in the upper annular groove and the lower annular groove, when rainwater and the like enter the upper annular groove and the lower annular groove, the water-swelling adhesive tapes can swell when meeting water, so that a sealing effect is further achieved, and the sealing effect is better; third, the cross-sectional width of meeting water inflation adhesive tape is less than go up annular groove and the degree of depth of annular groove down, the cross-section of meeting water inflation adhesive tape is "U" style of calligraphy, forms the bulge loop with the sheath inboard that last annular groove corresponds with lower annular groove, and the bulge loop card is in meeting water inflation adhesive tape for bulge loop top and two sides are surrounded by meeting water inflation adhesive tape, and sealed effectual, joint strength is big, and the shock resistance of sheath is good.
