Detailed description of the invention
As requested, the detailed description of the invention of the present invention will be disclosed here.It is to be understood, however, that
Embodiments disclosed herein is only the exemplary of the present invention, and it can be presented as various shape
Formula.Therefore, the detail disclosed here is not to be considered as limiting, and is merely possible to right
Require basis and as be used for instruct those skilled in the art in reality any appropriate in the way of
Differently apply the representational basis of the present invention, including using various features described herein and tying
Close and be likely not to have the feature clearly disclosed here.
As Figure 1-5, the insulator 200 of the present embodiment is porcelain post insulator, insulator 200
Including the body of rod 21 with from the outward extending some full skirts 20 of the body of rod, the auxiliary umbrella cover 100 of the present embodiment
Inner surface formed host cavity 10, host cavity 10 houses two panels full skirt 20, the shape of host cavity 10
Consistent with the external surface shape of insulator 200 corresponding position of this host cavity 10 cladding, host cavity
The full skirt 20 of full wafer is coated with by 10.Auxiliary umbrella cover 100 is away from the edge of insulator 200 axis
It is provided with lengthening umbrella 11, lengthens umbrella 11 stretching out the most radially outward, so can be greatly increased absolutely
The creep age distance of edge 200.The inner surface of auxiliary umbrella cover 100 is provided with protruding 12, protruding 12 and makes
The inner surface of auxiliary umbrella cover 100 and generation gap, full skirt 20 surface 15, be filled with bonding in gap 15
Agent, is bonded in auxiliary umbrella cover 100 on insulator 200 by binding agent, makes will not be subject between the two
The service life reduction of auxiliary umbrella cover 100 is caused to pollution.Protruding 12 is bar shaped, in a circumferential direction
It is uniformly distributed, makes binding agent be evenly distributed, make to fix more between auxiliary umbrella cover 100 and insulator 200
Add firmly.Protruding 12 is to be interrupted in the circumferential, to prevent obstruct binding agent to be full of whole gap 15.
Auxiliary umbrella cover 100 radially on be provided with opening 13, be used for opening host cavity 10 and full skirt 20 included in
In host cavity 10.Opening 13 edge is provided with bond regions 14, and auxiliary umbrella cover 100 is by scribbling bonding
The bonding strip of agent is pasted onto bond regions 14 and is bondd by opening 13.The two ends of auxiliary umbrella cover 100 are divided
Not having the sleeve part 16 being socketed on the body of rod 21, sleeve part 16 can effectively reduce auxiliary umbrella cover 100
The area that end contacts with insulator 200, reduces the area needing to close auxiliary umbrella cover 100 end,
Make between auxiliary umbrella cover 100 and insulator 200 fixing more firm, more difficult polluted by the external world.
As it is shown in figure 5, four auxiliary umbrella cover 100 for the embodiment of the present invention are arranged on insulator 200
