Abstract
Provided is a compression joint clamp of a steel-cored aluminum strand. Two split semi-ring clamp sheets are riveted through a hinge shaft, a connection seat is respectively arranged at the free-ends of the two semi-ring clamp sheets, and the two connection seats form a whole through a fastener. When the compression joint clamp is used, an aluminum strand arranged outside an opening of an aluminum pipe extends to the position where transformation quantity is easy to gather to achieve the aim of preventing aluminum strand transformation quantity generated by the compression joint aluminum pipe from extending to an aluminum-strand wire, so that the transformation quantity can be digested on the steel-cored aluminum strand in the aluminum pipe. Under the effect of compression joint force, transformation of the steel-cored aluminum strand in the aluminum pipe cannot affect mechanical strength of the steel-cored aluminum strand, the transformation enables the steel-cored aluminum strand and the inner wall of the aluminum pipe to generate stronger combining force, and connection reliability is higher. Practice proves that the clamp effectively reduces scrappage of the wire, strand broken rate and expansion rate of the wire are reduced to 3% from 40%, and the effect is obvious.
Description
[technical field]
The invention belongs to a kind of crimping clip that auxiliary steel reinforced aluminium conductor connects with aluminum pipe in power construction.
[technical background]
Steel reinforced aluminium conductor is when its connector and aluminum pipe crimping; Because the steel core of outer field aluminium stranded conductor modular ratio internal layer is little; Make that the elongation of aluminium stranded conductor is more much bigger than steel core after the aluminum pipe crimping, thereby occur producing relative displacement between aluminium thigh and steel core, the aluminium thigh ectonexine; Moreover; Since the crimping position be from aluminum pipe middle part gradually to the end transition, thereby the extensional amount that makes the aluminium thigh gather towards the mouth of pipe of aluminum pipe, finally make steel reinforced aluminium conductor broken lot and swelling near the aluminum pipe mouth of pipe, occur; And this phenomenon will cause aluminium thigh ectonexine lead force difference to occur; Thereby reduce the mechanical strength of steel reinforced aluminium conductor, the minimizing of outer flow passage surface sections, resistance are increased be prone to heating, have certain potential safety hazard; And presentation quality is also poor, is difficult to reach electric power and checks and accepts connection mouth of pipe standard quality requirement.
[summary of the invention]
For solving the problems of the technologies described above; The present invention aims to provide a kind of steel reinforced aluminium conductor crimping clip; By this clip, steel reinforced aluminium conductor is when connector and aluminum pipe crimping, and steel reinforced aluminium conductor broken lot and swelling can not occur near the aluminum pipe mouth of pipe; Thereby help guaranteeing lead mechanical strength, eliminate safe hidden trouble, make coupling meet electric power and check and accept quality requirement.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: the architectural feature of this steel reinforced aluminium conductor crimping clip is: two semi-circular hoop sheets of split are riveted together by a hinge; On the free-end of said two semi-circular hoop sheets, be respectively equipped with a Connection Block, two Connection Blocks be tightened to integral body by securing member; The width of said semi-circular hoop sheet is 10-15 a times of two formed interior circular diameters of semi-circular hoop sheets.
As preferably, said securing member is made up of a bolt and a wing nut, and an end of this bolt is positioned in the screw of Connection Block, and said wing nut revolves the other end of putting at said bolt.
As preferably, the width of said semi-circular hoop sheet be two semi-circular hoop sheets formed in 12 times of circular diameters.
Beneficial effect: the present invention in use; The extensional amount that is located at the outer steel reinforced aluminium conductor of the aluminum pipe mouth of pipe is prone to gather the place; Reach and stop aluminium thigh deflection that the crimping aluminum pipe produced, the extensional amount is digested on the steel reinforced aluminium conductor in aluminum pipe to the axially extended purpose of aluminium thigh lead.And steel reinforced aluminium conductor is influenced by crimp force in the aluminum pipe, and the distortion that is produced not only can not influence the mechanical strength of steel reinforced aluminium conductor, but also can produce more powerful adhesion because of this distortion makes steel reinforced aluminium conductor and aluminum pipe inwall, and connection reliability is higher.Facts have proved, use the scrappage that has effectively reduced lead behind this clip, lead broken lot, bulging rate have reduced to 3% from 40%, and effect is obvious.
[description of drawings]
Fig. 1 is the planar structure sketch map of one embodiment of the invention.
Among the figure: hoop sheet 1, interior circle 11, bolt 2, wing nut 3, Connection Block 4, auricle 5, hinge 51.
[embodiment]
Referring to Fig. 1.Two semi-circular hoop sheets 1 of split are riveted together by hinge 51.During practical implementation, can on the hoop sheet at hinge 1 riveted joint position, auricle 5 be set, both make things convenient for hinge 51 riveted joints, not influence two hoop sheets, 1 formed interior circle 11 again and admit steel reinforced aluminium conductors.A Connection Block 4 is set respectively on the free-end of two semi-circular hoop sheets 1, whole as long as the shape of this Connection Block can form two Connection Blocks 4 through securing member.During practical implementation, said securing member can be a bolt 2 and a wing nut 3, and an end of bolt 2 is positioned in the screw of a side Connection Block 4, and wing nut 3 revolves the other end of putting at said bolt 2.During use,, and steel reinforced aluminium conductor is embraced as long as the free-end of 3, the two semi-circular hoop sheets 1 of wing nut of screwing will lump together.
A key technology of the present invention is the selected of semi-circular hoop sheet 1 width; Through repeatedly practising; Be gathering of the extensional amount of eliminating the outer aluminium thigh of the aluminum pipe mouth of pipe; Reach and stop aluminium thigh deflection that the crimping aluminum pipe produced, the extensional amount is digested on the steel reinforced aluminium conductor in aluminum pipe to the axially extended purpose of aluminium thigh lead, the width of its semi-circular hoop sheet 1 be preferably two semi-circular hoop sheets formed in circle 11 diameters 10-15 doubly; In this scope, can both effectively stop aluminium thigh deflection that the crimping aluminum pipe produced to the axially extended purpose of aluminium thigh lead; Present embodiment adopts 12 times width, that is: when interior circle 11 diameters of admitting steel reinforced aluminium conductor are 5 millimeters (when the line that also is appreciated that into steel reinforced aluminium conductor directly is 5 millimeters), and the width of hoop sheet 1 is 60 millimeters.
