Abstract
The utility model relates to the technical field of a composite insulator, particularly to the composite insulator with an end sealing structure, which comprises a core rod, a fitting sleeved at the end of the core rod and a protection sleeve covered on the outer wall of the core rod. The fitting comprises a fitting body and a protrusion arranged at the tail end of the fitting body. The protrusion is arranged around the outer wall of the fitting body. A sealing rubber formed into an integrated body with the protection sleeve in a high temperature vulcanizing manner is arranged in a cavity between the protrusion and the core rod on the outer wall of the protrusion. As the silicon rubber layer formed into the integrated body with the protection sleeve in the high temperature vulcanizing manner is formed between the core rod and the end of the fitting, high-intensity sealing of the composite insulator is realized, safety performance of the composite insulator is better, and sealing effect of the composite insulator is also difficultly destroyed by corrosion of external environment even if the composite insulator is exposed in a severe environment.
Description
Technical field
The utility model relates to the composite insulator technical field, particularly a kind of composite insulator with end seal structure.
Background technology
Along with the development of power industry, ultra-high-tension power transmission line requires increasingly high for weight, anti-soil sudden strain of a muscle ability and the sealing property of composite insulator.In the running of composite insulator, the sealing problem of composite insulator gold utensil end directly influences the safety of plug, if its hermetically-sealed construction is destroyed, outer water branch invades plug, thereby causes the corrosion brittle failure of plug.
In the prior art; Composite insulator includes plug, be sheathed on the gold utensil of plug end and be coated on the sheath of plug outer wall; Plug and sheath all insert in the inner chamber of this gold utensil, are filled with the room temperature vulcanization fluid sealant between the inner chamber of gold utensil and the sheath, thereby form hermetically-sealed construction.Yet its defective is: 1) the manual operating procedure of smearing fluid sealant complicated, be difficult to control, when fluid sealant and gold utensil cohesive force difference, the small slippage between plug and the gold utensil will cause seals to be cracked, even the phenomenon of fluid sealant disconnection takes place when serious.2) complex structure, the control point is many, in case have an accident, maintenance difficulty is big.
Therefore, to deficiency of the prior art, needing badly provides a kind of simple in structure, good seal performance, composite insulator that security reliability is high.
Summary of the invention
The purpose of the utility model is to avoid weak point of the prior art and a kind of simple in structure, good seal performance, the composite insulator with end seal structure that security reliability is high is provided.
The purpose of the utility model realizes through following technical measures:
A kind of composite insulator with end seal structure is provided; Include plug, be sheathed on the gold utensil of plug end and be coated on the sheath of plug outer wall; Said gold utensil includes gold utensil body and the convexity that is arranged at said gold utensil body tip; Said protruding ring is provided with in the cavity between the outer wall of said convexity, said convexity and the said plug and the high temperature vulcanized fluid sealant that is shaped to one of said sheath around the outer wall setting of said gold utensil body.
Wherein, said convexity is extended the end of said gold utensil body, said convexity and said this body by integral forming of gold utensil.
Wherein, the junction of said convexity and said gold utensil body tip forms a step.
Wherein, be provided with fluid sealant in the said step.
Wherein, said fluid sealant is high temperature vulcanized silicon rubber.
Wherein, said plug is the epoxy resin fiberglass pipe with hollow-core construction.
Wherein, the outer wall of said sheath is provided with full skirt, and said full skirt is big umbellule and alternately arranges.
Wherein, said sheath and said full skirt integral injection molding are coated on said plug.
The beneficial effect of the utility model:
The composite insulator with end seal structure of the utility model; Include plug, be sheathed on the gold utensil of plug end and be coated on the sheath of plug outer wall; Gold utensil includes gold utensil body and the convexity that is arranged at the gold utensil body tip; Protruding ring is provided with and the high temperature vulcanized fluid sealant that is shaped to one of sheath in the cavity between protruding outer wall, convexity and the plug around the outer wall setting of gold utensil body.Compared with prior art, because gold utensil directly is crimped on plug, the silastic-layer of formation and the high temperature vulcanized moulding of sheath one has been realized high-intensity sealing between the end of gold utensil and the plug, and its security performance is better.Above-mentioned through high temperature vulcanized integrated silastic-layer, reduced interface and sealing operation, strengthened sealing effectiveness.The terminal bulge-structure that is provided with of gold utensil; Be provided with high-temperature silicon disulfide rubber in the cavity between protruding outer wall, convexity and the plug; Even composite insulator is exposed in the rugged environment; The erosion of external environment also is difficult to destroy its sealing effectiveness, and has increased the adhesion between sheath and the gold utensil, and the external force factor of having avoided in transportation, installation and maintenance process, being produced strips down sheath from gold utensil and plug.

Gold utensil 2, gold utensil body 21, convexity 22, step 221;
Sheath 3, full skirt 4, fluid sealant 5.
Embodiment
In conjunction with following examples the utility model is described further:
The embodiment of the composite insulator with end seal structure of the utility model such as Fig. 1 and Fig. 2 and shown in Figure 3 include plug 1, are sheathed on the gold utensil 2 of plug 1 end and are coated on the sheath 3 of plug 1 outer wall.
Be provided with and the sheath 3 high temperature vulcanized fluid sealants 5 that are shaped to one in the cavity between protruding 22 outer wall, convexity 22 and the plug 1.Elastically-deformable interaction through plastic deformation of metal and fluid sealant 5 has realized high-intensity sealing.
Because gold utensil 2 directly is crimped on plug 1, when injection moulding sheath 3, be provided with fluid sealant 5 in the cavity between convexity 22 and the plug 1, play the effect of sealing ring, reduced interface and sealing operation simultaneously, strengthened sealing effectiveness.
Concrete, protruding 22 extend the end of gold utensil body 21, and protruding 22 is one-body molded with gold utensil body 21.
More specifically, convexity 22 forms a step 221 with gold utensil body 21 terminal junctions, is provided with fluid sealant 5 in the step 221, to play the effect of sealing; When injection moulding 1, make fluid sealant 5 can coat whole step 221, thereby can increase the adhesion between fluid sealant 5 and the gold utensil 2, to avoid sheath 3 because external force factor strips down from gold utensil 2 and plug 1.
The epoxy resin fiberglass pipe of plug 1 for having hollow-core construction.
Preferably, the outer wall of sheath 3 is provided with full skirt 4, and in the present embodiment, full skirt 4 is big umbellule alternately to be arranged, and full skirt can be one-body molded, also can distinguish moulding, is bonded in the outside of sheath 3 then through viscose glue.
Preferred, sheath 3 is coated on plug 1 with full skirt 4 integral injection molding.
Should be noted that at last; Above embodiment only be used to explain the utility model technical scheme but not to the restriction of the utility model protection range; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model, and do not break away from the essence and the scope of the utility model technical scheme.
