Specific embodiment
With reference to Fig. 1, the utility model proposes a kind of water proof and dust proof insulator cap, including：Lower cap 1, upper cap 2, bar portion 3
With umbrella portion 4.
With reference to Fig. 2, Fig. 3, lower cap 1 is is inverted barrel-like structure.Upper cap 2 is mounted on lower cap 1, and upper 2 inside of cap is cavity,
Top offers rod aperture 21.The notch 22 for connecting its inner cavity and rod aperture 21, notch 22 and upper 2 wall of cap are offered on upper cap 2
Have a common boundary for up-narrow and down-wide horn shape.With reference to Fig. 4, bar portion 3 is up-narrow and down-wide horn shape, and is matched with notch 22.Such as
This, bar portion 3 can be inserted in upper cap 2 by notch 22, and the top of bar portion 3 is stretched out from rod aperture 21；Then, by bar in upper cap 2
Portion 3 moves up, and can prevent bar portion 3 from deviating from from notch 22.Similarly, the diameter of 3 bottom end of bar portion is set greater than the straight of rod aperture 21
Diameter can prevent bar portion 3 from deviating from from rod aperture 21.
In present embodiment, limiting plate 5 is installed in upper cap 2, limiting plate 5 is mounted on by spring 6 on lower cap 1, spring 6
Under normality, limiting plate 5 rises support and multiplies bar portion 3 so that bar portion 3 moves up；Limiting plate 5 is pushed, can bar portion be dismounted by notch 22
3.In present embodiment, 3 bottom end of bar portion is oval calotte, and limiting plate 5 is equipped with and the matched groove in 3 bottom end of bar portion.
In present embodiment, bar portion 3 is equipped with external screw thread 31, and distance of the external screw thread 31 apart from 3 bottom of bar portion is less than upper cap 2
The depth of inner cavity.4 middle part of umbrella portion is equipped with perforation, is equipped in perforation and is more than bar with the matched internal thread of external screw thread, the diameter in umbrella portion 4
The diameter in hole 21.In this way, umbrella portion 4 and bar portion 3 can be connected through a screw thread, after bar portion 3 is inserted into cap 2, assembled by umbrella portion 4
Onto bar portion 3, one, bar portion 3 can be limited by umbrella portion 4, bar portion 3 is avoided to move down；Two, it can be by umbrella portion 4 to bar
Hole is blocked, and rainwater dust etc. is avoided to be polluted by rod aperture 21 into upper cap 2.Specifically, the upper cap 2 of the covering of umbrella portion 4, with
Notch 22 is protected.In present embodiment, spring 6 and limiting plate 5 are that conductive metal is made.
In present embodiment, upper cap 2 is rounded structure, is endangered to avoid wedge angle.Similarly, lower cap 1 is rounded structure.
