Description
Technical field
The utility model relates to insulator technology field, is specifically related to the composite insulator between a kind of umbrella sheath and plug with strong bonding force.
Background technology
Composite insulator generally comprises plug, umbrella sheath and gold utensil, first by compression joint technique, plug and gold utensil are crimped together, then the plug be crimped together and gold utensil are positioned in the mould of shaping umbrella sheath, after melten gel injection mo(u)lding, umbrella sheath is coated on the outside of plug and part gold utensil, namely forms composite insulator.
Existing composite insulator, as shown in Figure 1, because the bonding quality between umbrella sheath 10 and plug 40 is unstable, in the Long-Time Service process of composite insulator, likely depart between umbrella sheath 10 and plug 40, and then bring corresponding electric fault, have a strong impact on the serviceability of composite insulator; In addition, due to the impact of injection technique and injection mould structure, the umbrella sheath 10 of existing composite insulator can produce a lot of overlaps, not only can produce overlap 30 on the die joint of mould, also can produce overlap 30 at the outer toroid place 20 of the umbrella sheath 10 perpendicular to die joint, the overlap 30 at umbrella sheath 10 outer toroid place 20 not only increases the labour intensity of follow-up deflashing 30, and after removing overlap 30, originally the position at overlap 30 place becomes the position that in umbrella sheath 10, electric property is the weakest, affects the electric property of whole composite insulator.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, and provides the composite insulator that between a kind of umbrella sheath sheath and plug, bonding force is strong, umbrella sheath outer toroid place overlap is few.
The purpose of this utility model is achieved through the following technical solutions:
The composite insulator between a kind of umbrella sheath and plug with strong bonding force is provided, comprise gold utensil, plug and umbrella sheath, the two ends of described plug are inserted in the lock chamber of two described gold utensils respectively, described umbrella sheath is coated on the outside of exposed described plug outside described gold utensil, described umbrella sheath adopts Integral-structure type mould integral injection molding, described umbrella sheath comprises main body sheath and evagination in the circular umbrella portion of described main body sheath, bonding agent is provided with between described main body sheath and described plug, the plane orthogonal that described circular umbrella portion is formed is in the die joint of the mould of shaping described umbrella sheath.
Wherein, the length in adjacent described circular umbrella portion is equal or not etc.
Wherein, the width in adjacent described circular umbrella portion is equal or not etc.
Wherein, described main body sheath two ends are coated on the outside formation encapsulate head of two described hardware ends respectively.
The beneficial effects of the utility model:
There is between a kind of umbrella sheath of the present utility model and plug the composite insulator of strong bonding force, its structure comprises umbrella sheath and plug, umbrella sheath is coated on the outside of plug, umbrella sheath comprise main body sheath and evagination in described main body sheath and with it integrated circular umbrella portion, when the shaping umbrella sheath of Integral-structure type mold injects, by the use of the bonding agent between main body sheath and plug and the control of injection technique, can for providing enough bonding forces between described main body sheath and described plug, the hidden danger that elimination umbrella sheath and plug depart from, and the plane orthogonal that described circular umbrella portion is formed is in the die joint of the mould of shaping described umbrella sheath, overlap only remains on the die joint of umbrella sheath, relative to umbrella sheath of the prior art, the utility model eliminates overlap and exists in the plane that circular umbrella portion formed, and then reduce the labour intensity of follow-up removal overlap, also ensure that the electric property of whole composite insulator simultaneously.
Accompanying drawing explanation
