Circuit is electrically connected, and the inner of contact rod electrically connects through O-shaped binding post with capacitor, the optional hexagonal shape of clamping part, convenient wrench
Clamping.
Present invention sticking plaster and silicon rubber substitute ceramic material, significantly reduce weight, do not break up, service life
Long, mechanical strength can meet and use, and insulating properties are high, and anti-fouling effect is splendid.
It should be noted that sticking plaster has non-friable, intensity is high, and the characteristics of good insulation preformance, but sticking plaster is in itself
There is not resistant, in addition, plastics should not be enclosed within outside nut with radiating insulating oil directly contact, present invention silicone rubber sleeve,
The technical problem of nut and radiating insulating oil directly contact can be solved, silicon rubber umbrella is enclosed within sticking plaster and can solve antifouling technology
Problem, while improving insulating properties.
After preventing from expanding with heat and contract with cold, occurs gap between sticking plaster and contact rod, also including the second sealing ring, this second
Sealing ring is arranged between the end face of the threaded post and the inner bottom surface of the nut and is pressed by nut, the radiating insulating oil
Gap internal leakage that can not be between contact rod and sticking plaster.
Preferably, the upper end of the silicone rubber sleeve extends to the annulus end face for wrapping up the nut, under silicone rubber sleeve
End is extended between the end face of the threaded post and the inner bottom surface of the nut.
Preferably, the top of the metal top cap is provided with the first in-flanges, can wrapping portion sealing, metal top cap
Bottom be also equipped with the second in-flanges.
Preferably, the second in-flanges that the upper connecting column has tapered portion, the metal top cap is enclosed within tapered portion.
Preferably, the inner bottom surface of the nut is provided with taper, the shape of second sealing ring is also taper.Pass through
