Description
Technical field
The utility model is related to a kind of spiral interface floor deconcentrator, relates generally to junction box field.
Background technology
Patent No. 201520673582.X discloses a kind of squash type deconcentrator, mainly including contact rod, fixed cover, pressure
Piece and pressing plate, its center platen and compressing tablet are that a wire termination is fixed in a combination, and contact rod and fixed cover combine fixed another for another
One wire termination, fixation is set in the periphery of contact rod, is provided with bolt on fixed cover, bolt end against contact rod one
Face, when fixed, wire extended into fixed cover and is contacted with the another side of contact rod, then by regulating bolt,
And then fixed cover and contact rod to wire extrude and reach the effect fixed to wire.The program has when fixed wire
Larger drawback, because must be solid and reliable according to related request spiral interface floor deconcentrator conductive contact, fixed cover and conduction
Although rod temporarily fixes tight during wire is extruded, deformation occurs when wire is squeezed, it is covert
The extruding force of script is eliminated, therefore is easy to the phenomenon for loosening occur.
Utility model content
For above the deficiencies in the prior art, the utility model proposes a kind of spiral interface for improving and being oriented to fixed firmness
Floor deconcentrator.
To reach above-mentioned purpose, the technical solution of the utility model is：Including the mutual box body and lid for fastening, in box body
Pressing plate and wedge are fixed with ladder, while being additionally provided with several contact rods in box body, contact rod is fixed on box including left side
Conducting end and right side on body extend in the fixing end outside box body, and conducting end offsets with wedge, and fixing end is axially arranged with fixing hole,
The side wall perimeter of the fixing hole is male-tapered structure, and the pyramidal structure right-hand member diameter is less than left end, the side-wall shaft of fixing hole to point
Some valves are segmented into, the internal thread segment and the inner cone hole section on right side being cased with outside fixing end in extruded sleeve, extruded sleeve including left side, inner cone
The male-tapered respective outer side edges of hole section and fixing end, internal thread segment coordinates with contact rod screw thread.
Know-why of the present utility model is as follows：When entering row conductor using the present apparatus and fix, rotary squeezing set to the right,
Then it is directed in end insertion fixing hole, finally rotary squeezing set to the left, due to fixing end outer peripheral face being cone in extruded sleeve
Shape structure, therefore when rotary squeezing covers to the left, the fixing end on right side will be extruded inwardly, and then wire is locked in into fixing hole
In.
The beneficial effects of the utility model are as follows：
Speed is fast, simple to operate, need to only inject in fixing hole wire, then to the left rotary squeezing set can just realize it is right
The fixation of wire；
Fixation, fully meets relevant regulations of the country at electric aspect, and being directed at the power being subject in fixation procedure is
The inside extruding of the cylindrical entirety of outer circumference surface, i.e. wire, in fixation procedure, wire will not be deformed because of extruding.Wire
End can Reusability, do not damage wire termination.
Further, fixing hole inwall circle is circumferentially with some anti-skid bulges, and anti-skid bulge can prevent wire from departing from fixation
In hole, wire is carried out anti-skidding.
Further, the anti-skid bulge improves skidproof effect to be uniformly arranged in fixing hole inwall loop configuration.
Further, the anti-skid bulge is to be uniformly arranged the raised points in fixing hole inwall, and raised points can improve wire and consolidate
Determine the mutual coefficient of friction in hole.
Further, the right-hand member that box body is fixed with contact rod is provided with annular groove, contact rod and extruded sleeve screw-internal thread fit
External screw thread is arranged in annular groove, and external screw thread is arranged in annular groove, and the screw thread can be protected, and prevents outer bound pair
The screw thread produces damage.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
The accompanying drawing to be used needed for description is briefly described, it should be apparent that, drawings in the following description are only new this practicality
Wherein two width of type, for those of ordinary skill in the art, without having to pay creative labor, can be with root
