Abstract
The utility model discloses a lightning protection type insulation puncture wire clamp comprising an upper insulation seat, a lower insulation seat, two puncture blade seats arranged in the upper insulation seat and the lower insulation seat, an upper positioning metal member, a lower positioning metal member and a screw bolt fastening assembly. A circular through holes which penetrates through the upper insulation seat in a vertical direction is arranged in the center portion of the upper insulation seat. A screw-tight force bearing portion of a screw rod is exposed outside the circular through hole. A screw nut is a square column provided with an inner screw hole. The central portion of the lower insulation seat is provided with a square accommodating chamber used for the arrangement of the screw nut. The bottom wall of the lower insulation seat is provided with a connection aperture arranged to be right corresponding to the inner screw hole of the screw nut. According to the utility model, the inner screw hole of the square screw nut is exposed outside through the connection aperture; simultaneously, since the square screw nut is electrified, the inner screw hole can be utilized to enable the lightning protection type insulation puncture wire clamp to be externally connected with a lightning arrester, so that impact currents generated by thunder can be effectively introduced into ground wires; cables and armour clamps at the position of the lightning protection type insulation puncture wire clamp can be prevented from being damaged by the thunder; and normal operation of electric power lines is further guaranteed.
Description
Technical field
The utility model belongs to electric armour clamp structure-design technique field, is specifically related to a kind of lighning proof type insulation puncture line clamping.
Background technology
In the construction of power circuit, often need to two wires be electrically connected with insulation puncture line clamping.
Tradition insulation puncture line clamping comprises insulating base, lower insulating base, is arranged on upper puncture blade in insulating base, is arranged on the lower puncture blade in lower insulating base; In upper insulating base and lower insulating base, be equipped with multiple mounting grooves, the independent moulding of the blade that respectively punctures is made, and the blade that respectively punctures is fixed in a corresponding mounting groove.This structure need to be installed each puncture blade separately, because puncture blade needs good stability, higher to the requirement on machining accuracy of each mounting groove and puncture blade; Because needs are installed each puncture blade one by one, its assembly operation is comparatively loaded down with trivial details in addition.The scope of application of insulation puncture line clamping is very wide, but because insulation puncture line clamping is used for connecting two cables, with respect to other position of cable, this place's resistance is larger, and in the time that thunderbolt occurs, this place is as easy as rolling off a log to be damaged by thunder and lightning ablation, causes power failure.
Utility model content
The purpose of this utility model is to provide a kind of lighning proof type insulation puncture line clamping that can be connected in series lightning arrester.
The technical scheme that realizes the utility model object is: a kind of lighning proof type insulation puncture line clamping, comprises insulating base, lower insulating base, is arranged on two puncture tool rests, upper positioning metal part, lower positioning metal part and bolt fastening components in insulating base and lower insulating base; Upper insulating base center is provided with the circular through-hole running through along the vertical direction, and the forced section of tightening of described screw rod exposes this circular through-hole; Described nut is the square column type that is provided with inner bolt hole, and the middle part of lower insulating base is provided with the square containing cavity for this nut is set, and the diapire of lower insulating base is provided with the connection holes just described nut inner bolt hole being arranged.
In such scheme, the center of described two punctures tool rest, upper positioning metal part and lower positioning metal parts is equipped with the waist-shaped hole running through along the vertical direction, described bolt fastening component comprises screw rod and nut, screw rod is screwed onto in nut through after each waist-shaped hole from top to bottom successively, thereby upper positioning metal part, two puncture tool rests and lower positioning metal part are connected and fixed successively.
The utility model exposes the inner bolt hole of square nut by connection holes, simultaneously because square nut is charged, can utilize this inner bolt hole external arrester, thereby in the time of thunderbolt, the impulse current effectively thunder and lightning being produced is introduced ground wire, thereby prevent that it from damaging this place's cable and gold utensil, thereby ensure the normal operation of power circuit.
