Abstract
The utility model discloses a composite insulator comprising an armor clamp, a core rod and a sheath, a bonding layer is disposed between the armor clamp and the core rod and prepared by cement materials, and one end, close to the armor clamp, of the core rod is provided with an annular groove. According to the technical scheme, the cement bonding layer is disposed between the core rod and the armor clamp and prepared by the cement materials, and the armor clamp and the core rod are fixedly connected with each other after cement is solidified; hardness is high and stability is good after the cement is solidified, and hidden trouble that the armor clamp and the core rod are possibly disconnected during operation is prevented; and the core rod is inserted into the armor clamp before the cement is solidified, the cement is squeezed into the annular groove of the core rod, and the core rod is clamped and firmed after the cement is solidified.
Description
Technical field
The utility model relates to a kind of special control, and more particularly, it relates to a kind of composite insulator.
Background technology
The gold utensil of traditional composite insulator adopts crimping to connect with plug, by this gold utensil, is connected with plug parts, and such gold utensil and the fixed form of plug are exactly plug and gold utensil crimping.It is stressed that this mode is plug periphery, can not utilize to greatest extent plug to transmit power, and bearing tension is limited, and gold utensil and plug may depart from, and brings hidden danger to the circuit operation of insulator.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of gold utensil and the close-connected composite insulator of plug.
For achieving the above object, the utility model provides following technical scheme: a kind of composite insulator, comprise gold utensil, plug and sheath, and between described gold utensil and plug, be provided with adhesive layer, described adhesive layer consists of cement material, and described plug is provided with annular groove near gold utensil one end.
By adopting technique scheme, between plug and gold utensil, be provided with cementing layer, adhesive layer is cement material, after theing cement solidifies, gold utensil is fixedly connected with plug, and after theing cement solidifies, hardness is high, good stability, the hidden danger of avoiding gold utensil and plug may depart from when operation, before theing cement solidifies, plug is injected to gold utensil, cement is got in plug annular groove, blocks plug and play reinforcement effect after theing cement solidifies.
Described gold utensil is pottery.
By adopting technique scheme, ceramic surface has good hydrophobicity, can avoid because rainwater is deposited in gold utensil and sheath gap, and cause infiltration, and ceramic gold utensil and cement fiting effect are better.
Described plug is that glass-epoxy forms.
By adopting technique scheme, glass-epoxy electric property is superior, and mechanical strength is high, and inner bearing ratio common iron is high 2 times, is 8 ~ 10 times of high strength china material, has effectively improved the reliability of safe operation.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment composite insulator hardware structural representation;
Fig. 2 is the utility model embodiment composite insulator overall diagram.
In figure: 1-gold utensil, 2-adhesive layer, 3-plug, 4-annular groove, 5-sheath.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
A composite insulator, comprises gold utensil 1, plug 3 and sheath 5, between described gold utensil 1 and plug 3, is provided with adhesive layer 2, and described adhesive layer 2 consists of cement material, and described plug 3 is provided with annular groove 4 near gold utensil 1 one end.
By adopting technique scheme, between plug 3 and gold utensil 1, be provided with cementing layer 2, adhesive layer 2 is cement material, after theing cement solidifies, gold utensil 1 is fixedly connected with plug 3, and after theing cement solidifies, hardness is high, good stability, the hidden danger of avoiding gold utensil 1 and plug 3 may depart from when operation, before theing cement solidifies, plug 3 is injected to gold utensil 1, cement is got in plug 3 annular grooves 4, blocks plug 3 and play reinforcement effect after theing cement solidifies.
Described gold utensil 1 is pottery.
By adopting technique scheme, ceramic surface has good hydrophobicity, can avoid because rainwater is deposited in gold utensil 1 and sheath 5 gaps, and cause infiltration, and ceramic gold utensil 1 and cement fiting effect are better.
Described plug 3 is glass-epoxy composition.
By adopting technique scheme, glass-epoxy electric property is superior, and mechanical strength is high, and inner bearing ratio common iron is high 2 times, is 8 ~ 10 times of high strength china material, has effectively improved the reliability of safe operation.
The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
