Enter to cover after wire in hole strutted by separated time tip nail, the wire of bifurcated will be initially positioned toward annular groove inner bending, wire
And be difficult to release out outside middle conductive head.
Further, the separated time tip nail root passes through the transition of First Transition face, the annular groove with male threaded stub
With entrance hole by the second transition face transition, First Transition face is parallel with the second transition face.When tightening outer lock-nut, first
Transition face and the second transition face are close, and the wire of bifurcated can be caused to be bent, also, wire and the First Transition face of bending,
The wall contact of second transition face and annular groove, produces bigger friction.
Further, the separated time tip nail root diameter (RD) is the 1/4 to 1/3 of male threaded stub diameter so that insertion set hole
In wire have sufficient length by separated time tip nail strut.
Further, the First Transition face and the second transition face are plane or inclined-plane or cambered surface so that work as First Transition
Face and the second transition face close to when, wire is gradually bent.
Further, the wall of the annular groove is the wide conical surface in inswept rear end.
Further, by the 3rd transition face transition between the annular groove and screwed hole, the 3rd transition face is the conical surface.
Further, the middle conductive head periphery and outer lock-nut periphery are equipped with outer-hexagonal, are easy to it to match somebody with somebody with spanner
Close.
The beneficial effects of the utility model are as follows：
（1）Fast energy-saving conductive contact is made up of two kinds of parts of middle conductive head and outer lock-nut in the middle of such nail type,
The moulding that tip is followed closely is provided with reference to middle conductive end surface, when outer lock-nut is tightened, tip nail is more outward in lock-nut
Insertion, the volume in outer lock-nut inner sleeve hole is gradually decreased, and forms an environment for facilitating gripping by wire, its conjunction simple in construction
Reason, clamping effect is good, improves electrical efficiency, reduces power consumption.
（2）Fast energy-saving conductive contact will not be broken, it is necessary to bend unlike the wire clamp of prior art in the middle of such nail type
Its bad mechanical structure, can Reusability；
（3）Fast energy-saving conductive contact is operated without hydraulic tongs in the middle of such nail type, and operating personnel can take insulation hand
Set（Or by small instruments and tools such as spanners）Livewire work can be realized, can't be gone out first safe hidden as mentioned in the background art
Suffer from, using quite safe, be especially suitable for high-altitude hot line job.
