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 in the time of its connector and aluminum pipe crimping, because the steel core of outer field aluminium stranded conductor modular ratio internal layer is little, make after aluminum pipe crimping the elongation of aluminium stranded conductor more much bigger than steel core, thereby occur producing relative displacement between aluminium thigh and steel core, aluminium thigh ectonexine; Moreover, because crimping position is gradually to end transition from aluminum pipe middle part, thereby the extensional amount of aluminium thigh is gathered towards the mouth of pipe of aluminum pipe, finally make steel reinforced aluminium conductor near irriation aluminium pipe mouth, occur broken lot and swelling, and this phenomenon will cause aluminium thigh ectonexine wire to occur force difference, thereby reduce the mechanical strength of steel reinforced aluminium conductor, make the minimizing of outer flow passage surface sections, resistance increase easily heating, there is certain potential safety hazard, and presentation quality is also poor, is difficult to reach electric power and checks and accepts connection mouth of pipe specification quality requirement.
[summary of the invention]
For solving the problems of the technologies described above, the present invention aims to provide a kind of compression joint clamp of steel-cored aluminum strand, by this clip, steel reinforced aluminium conductor is in the time of connector and aluminum pipe crimping, steel reinforced aluminium conductor there will not be broken lot and swelling near irriation aluminium pipe mouth, thereby be conducive to guarantee wire mechanical strength, eliminate safe hidden trouble, make coupling meet electric power check and accept quality requirement.
For achieving the above object, the present invention has adopted following technical scheme: the architectural feature of this compression joint clamp of steel-cored aluminum strand is: two semi-circular hoop sheets of split are riveted together by a hinge, on the free-end of described two semi-circular hoop sheets, be respectively equipped with a Connection Block, by securing member, two Connection Blocks be tightened to entirety; The 10-15 of the interior circular diameter that the width of described semi-circular hoop sheet forms for two semi-circular hoop sheets doubly.
As preferably, described securing member is made up of a bolt and a wing nut, and one end of this bolt is positioned in the screw of Connection Block, and described wing nut is located on the other end of described bolt.
As preferably, 12 times of the interior circular diameter that the width of described semi-circular hoop sheet forms for two semi-circular hoop sheets.
Beneficial effect: the present invention in use, the extensional amount that is located at the steel reinforced aluminium conductor outside irriation aluminium pipe mouth is easily gathered place, reach and stop aluminium thigh deflection that crimping aluminum pipe produces to the axially extended object of aluminium thigh wire, make on the digested steel reinforced aluminium conductor in aluminum pipe of extensional amount.And steel reinforced aluminium conductor is affected by crimp force in aluminum pipe, the distortion producing not only can not affect the mechanical strength of steel reinforced aluminium conductor, but also can produce more powerful adhesion because 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 wire after this clip, wire broken lot, bulging rate have reduced to 3%, successful from 40%.
[brief description of the drawings]
Fig. 1 is the planar structure schematic diagram of one embodiment of the invention.
In figure: hoop sheet 1, inner 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.When concrete enforcement, can on hinge 1 is riveted the hoop sheet at position, auricle 5 be set, both facilitate hinge 51 to rivet, not affect again the inner circle 11 that two hoop sheets 1 form and receive steel reinforced aluminium conductor.The shape of this Connection Block a Connection Block 4 is set respectively on the free-end of two semi-circular hoop sheets 1, as long as can make two Connection Blocks 4 form entirety through securing member.When concrete enforcement, described securing member can be a bolt 2 and a wing nut 3, and one end of bolt 2 is positioned in the screw of a side Connection Block 4, and wing nut 3 is located on the other end of described bolt 2.When use, will be combined as long as screw the free-end of 3, two semi-circular hoop sheets 1 of wing nut, and steel reinforced aluminium conductor is embraced.
A key technology of the present invention is the selected of semi-circular hoop sheet 1 width, through repeatedly practising, for eliminating the gathering of extensional amount of the outer aluminium thigh of irriation aluminium pipe mouth, reach and stop aluminium thigh deflection that crimping aluminum pipe produces to the axially extended object of aluminium thigh wire, make on the digested steel reinforced aluminium conductor in aluminum pipe of extensional amount, the 10-15 that the width of its semi-circular hoop sheet 1 is preferably inner circle 11 diameters that two semi-circular hoop sheets form doubly, within the scope of this, can effectively stop aluminium thigh deflection that crimping aluminum pipe produces to the axially extended object of aluminium thigh wire, the present embodiment adopts the width of 12 times, that is: in the time receiving inner circle 11 diameters of steel reinforced aluminium conductor to be 5 millimeters (when the wire diameter that also can be understood as steel reinforced aluminium conductor is 5 millimeters), the width of hoop sheet 1 is 60 millimeters.
