Traditional high-tension electricity capacitive insulation that is used for the high-tension electricity conveying is generally pottery and processes, and comprises insulator body, and insulator body is provided with a plurality of full skirts, and its two ends are provided with metal connection assembly and metal installation component.What the conventional method that metal connection assembly, metal installation component are connected with insulator body generally adopted is the method for welding; Because the particularity of ceramic material; Machining accuracy is difficult to guarantee; Cause the concave-convex surface of ceramic material different, in order to improve itself and the sealing that is connected of metal connection assembly, metal installation component, the mode that generally needs to weld couples together them.The silver alloy welding that the mode that insulator body and metal connection assembly and metal installation component are coupled together adopts mostly; This has increased the insulator processing cost greatly; The viscous state that simultaneously this silver alloy is configured to smear easily need adopt the heavier acidic chemical medicine of pollution level, is unfavorable for protecting environment.
Have more drawback to ceramic insulator, insulator in the market adopts composite resin material to substitute traditional pottery mostly and processes insulator, and composite insulator is accepted by the user very soon owing to its various advantages that has and is widely used.The insulator that right capacitor is used to sealing property require high; In order to guarantee that its sealing property manufacturer has adopted a lot of ways that the metal installation component is connected with insulator body; So the sealing technology at metal installation component place is comparatively ripe; Because structurally there are bigger difference in metal installation component and metal connection assembly, the encapsulation process that is applicable to installation component is to metal connection assembly and inapplicable, thereby the sealing effectiveness at metal connection assembly place is still not satisfactory.
Existing metal connection assembly mainly is to connect insulator body through a hollow bolt; Present modal connected mode mainly contains two kinds: a kind of is direct and insulator body plastic packaging or compression molding of hollow bolt, and the inventor of present patent application finds to adopt the insulator arrangement of this connected mode to be used for the oil impregnate phenomenon can occurring on the capacitor; Another kind is through the top in the central bore of insulator body annular boss to be set; Through with stopping end and the below of annular boss be set on the hollow bolt, at annular boss and stop sealing ring is set between the end that the threaded portion of hollow bolt is connected with the wiring nut; Than first kind of connected mode, it is better to adopt this structure to connect sealing effectiveness; And because the central through hole of insulator body is circle with stopping to hold, this just causes when tightening the wiring nut, can producing a power together rotates hollow bolt thereupon, and then has destroyed original sealing state, oil leakage phenomenon occurs.Therefore, the structure of existing insulator arrangement has the improvements of need.
Summary of the invention
To the above-mentioned deficiency that exists in the prior art, the utility model provide a kind of can effectively guarantee product hermeticity can insulator arrangement.
The technical scheme that realizes the utility model purpose is:
A kind of insulator arrangement comprises insulator body that is provided with central through hole and the connector assembly that is arranged on said insulator body top; Form the annular boss that extends to the center on the top inwall of said insulator body central through hole; Said connector assembly comprises the binding post of being made up of wire connecting portion and connecting portion; The below of the connecting portion of said binding post annular boss in said central through hole, its wire connecting portion is stretched out from the top of central through hole; Between said annular boss and connecting portion, be provided with sealing ring; The outer peripheral wall of the connecting portion of said binding post is provided with convexity or groove, said central through hole inwall be provided with connecting portion on convexity or the groove or the convexity of groove corresponding matching.
In the technique scheme, said connector assembly also comprises wiring nut that matches with said wire connecting portion and the metal nut cap that is arranged on the insulator body top; Said wire connecting portion is for being provided with externally threaded screw rod, and said connecting portion is the boss that outwards is convexly equipped with out from the screw rod bottom.
In the technique scheme, being shaped as regular polygon, ellipse, being provided with the circle of breach or projection of said connecting portion.
In the technique scheme, the center of said binding post is provided with wiring hole vertically.
In the technique scheme, said insulator body comprises the resin inner core and is set in the elastometric boot that has full skirt on the said resin inner core; Be provided with the metal installation component that is fixedly connected with external equipment in the bottom of said insulator body.
The utlity model has positive effect:
The outer peripheral wall of the connecting portion of the said binding post in the utility model is provided with convexity or groove, said central through hole inwall be provided with connecting portion on convexity or the groove or the convexity of groove corresponding matching; Through adopting this structure when screwing the wiring nut, thus since the connecting portion of binding post and insulator body reliably be connected can not cause binding post become flexible or mobile, thereby guaranteed its sealing property.
