Summary of the invention
The purpose of this utility model provides the insulator of the effect of the effect that can play the insulation and support lead in power circuit and above-mentioned are-tight puncture gold utensil.
The purpose of this utility model is achieved through the following technical solutions:
A kind of piercing preventing arc insulator, it comprises: the wire clamp seat, that an insulating shield, is arranged at this insulating shield inside is attached thereto preventing arc rod, an insulator part that links to each other with the lower end of wire clamp seat that connects by the hole in this wire clamp seat, it also comprises a upper end and the metal cap that this insulator part lower end links to each other, and is set in turn in one of this wire clamp seat inside and moves a briquetting and a briquetting seat.
Wherein, this moves briquetting and is provided with a dovetail shaped projection, and this briquetting seat is provided with the corresponding dovetail groove of a shape, and this dovetail shaped projection is mounted slidably in this dovetail groove.
Wherein, this moves briquetting and this briquetting seat is located by hoodle.
Wherein, this lower surface that moves briquetting is provided with the groove that one or more are used to install puncture.
Wherein, its also comprise one with this wire clamp seat outer surface on screw thread fasten the nut that connects mutually.
Wherein, the upper surface both sides of this briquetting seat are respectively arranged with a projection.
Wherein, the upper end of this projection is routed up laterally.
Wherein, this preventing arc rod outside also is surrounded by insulating sleeve.
Wherein, the terminal end of this preventing arc rod relatively of this insulative grows 2mm at least.
Positive progressive effect of the present utility model is:
1, mobile briquetting and briquetting seat are assembled into one by modes such as swallow-tailed projection and grooves, and prevent that by the hoodle locate mode both break away from, make lead when being moved owing to reason such as expand with heat and contract with cold, mobile briquetting also moves thereupon, thereby avoids lead to be punctured scuffing.
2, the utility model not only can play insulation and support the effect of lead can also play the effect of above-mentioned are-tight puncture gold utensil in power circuit.
3, this moves two projections of the upper surface both sides of briquetting, and it has realized steadily synchronously mobile briquetting and wire clamp seat being fastened the effect that is connected together by a nut, has solved the problem of the fastening briquetting difficulty that punctures up and down in the former piercing preventing arc insulator.In addition because the insulating barrier of the penetrable insulated conductor of puncture and not with its strip off, has been avoided the water inlet and the corrosion of core.
4, owing to have insulating sleeve on the preventing arc rod, more than the overhanging 2mm of this insulating sleeve, metalwork preventing arc rod is exposed, do not influence the arcing distance between preventing arc rod and the following metal tool pin again, improved the insulation level of preventing arc rod.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
A kind of piercing preventing arc insulator, it comprises: an insulating shield 3, a wire clamp seat 4, a briquetting seat 5, move briquetting 11, a nut 6, a metal leg 9, an insulator part 2 and a preventing arc rod 7.
Wherein this wire clamp seat 4 is provided with the hollow body 43 that the bottom has ball recess 42, and it is used for holding successively lead 1 and mobile briquetting 11 and briquetting seat 5.The side of this wire clamp seat 4 is provided with hole 44, for fixing the using of these preventing arc rod 7 one ends.The lower end of this wire clamp seat 4 is connected with insulator part 2.
This briquetting seat 5 is provided with: be arranged at the projection 51 of its upper surface both sides, the adjacent sidewall of the hollow body of itself and this wire clamp seat 4 43 is in the arc-shaped, and the upper end of this projection 51 routs up (figure does not show) laterally, and this nut 6 comes off when preventing to dismantle; Run through also be provided with on its lower surface one with hereinafter described mobile briquetting 11 on dovetail shaped projection 112 corresponding dovetail grooves 53, for this move briquetting 11 within it portion slide.
Run through on these mobile briquetting 11 upper surfaces and be provided with a dovetail shaped projection 112, it is fastened in this dovetail groove 53, to realize that this moves the slip of briquetting 11 with respect to this briquetting seat 4, this dovetail shaped projection 112 is provided with a groove 110, in it hoodle can be set, move briquetting 11 and break away from from briquetting seat 5 in order to prevent this; Its lower surface is a circular arc, during use and lead 1 adjacent, the axial location of this lower surface is provided with two grooves 111, its inside can fix as required the puncture 52.
