Embodiment
Below in conjunction with concrete drawings and Examples the present invention is described further.
The supporting gold utensil of terminal of the present utility model is applicable to that composite core aerial condutor terminal connects.Gold utensil mainly comprises water conservancy diversion sleeve pipe, drainage plate, steel anchor, internal lining pipe.The lead terminal can be fixed on the strain insulator and be connected with shaft tower.
What Fig. 1,2 showed is the supporting gold utensil of terminal of the present utility model.This terminal type gold utensil mainly comprises the internal lining pipe 1 of the supporting gold utensil of terminal, steel anchor 2, and water conservancy diversion sleeve pipe 3 constitutes.Internal lining pipe 1 has two terminations 11 and 12, and the center has the through hole 13 of a diameter, is made by a kind of aluminum, but also can adopt other any metal material to make, and this material has certain ductility; Through hole 13 inner surfaces are smooth, are beneficial to aluminum pipe during smooth inner surface crimping and extend, can the scratch heart yearn.Steel anchor 2 comprises annular link 21, packing ring 22, annular burr 23, smooth section 24, the axial hole 25 of corresponding internal diameter; Smooth section 24 is to be made by a kind of low-carbon steel material, but also can adopt other any metal material to make, and this material has certain ductility, but ductility is less than the ductility of internal lining pipe 1 material; The degree of depth of the axial hole 25 of corresponding internal diameter.Water conservancy diversion sleeve pipe 3 is made by conductive metallic material, as aluminium.Water conservancy diversion sleeve pipe 3 comprises two terminations 30,31 and drainage plate 32, also has 34,35 and one of 36, two crimping starting points of one section conical transition zone marks to stop crimping mark 33 on water conservancy diversion sleeve pipe 3. Drainage plate 32 and 31 welding of terminal type water conservancy diversion sleeve pipe termination also are made of aluminum, are used for the terminal current transmission.
What Fig. 3,4 showed is the assemble flow schematic diagram of supporting gold utensil of terminal and lead 4.Lead 4 comprises conduction strand layer 41 and compounded yarn 42.The compounded yarn 42 of removing conduction strand layer 41 is installed to is embedded with in internal lining pipe 1 and the steel anchor 2, smooth section 24 parts to steel anchor 2 are carried out mechanical crimping, should begin near the place of annular burr 23 during crimping, the mouth of pipe until axial hole 25, crimping is from carrying out in regular turn, can not jump, the front and back mould should overlapping about 15mm.Should guarantee mould fully closed (but it should be noted that in the crimping process pressure can not greater than 85Mpa, as causing damage to plug) in the crimping process greater than 80Mpa.Smooth section 24 is subjected to mechanical crimping volume-diminished, extruding internal lining pipe 1, the ductility of internal lining pipe 1 is better than smooth section 24, and the material of internal lining pipe 1 will extend the space of filling up 42 of smooth section 24 and heart yearns in the crimping process, and the material of unnecessary internal lining pipe 1 will extend out from the mouth of pipe of internal diameter 25.Distortion by internal lining pipe 1 produces pressure to heart yearn 42, blocks heart yearn, can bear advantages of higher tensile strength to guarantee heart yearn.Water conservancy diversion sleeve pipe 3 is slided along the top of steel anchor 2 annular links 21, tightly be close together up to the packing ring 22 and annular link 21 sidepieces of drainage plate 32 with steel anchor 2.Subsequently three gauge points 33,34,35 that become axially to separate on the terminal type water conservancy diversion sleeve pipe 3 are carried out mechanical crimping.At first begin crimping up to gauge point 33 from gauge point 34, because the material of water conservancy diversion sleeve pipe 3 extends, termination 31 will form tension force between extruded gasket 22 and the annular link 21 in the crimping process; Again along the termination 30 of gauge point 35 crimping up to water conservancy diversion sleeve pipe 3; After the crimping, form very big tension force in the inner meeting of described terminal type gold utensil.Wherein crimping should not carried out in the zone between gauge point 34 and the gauge point 35, and this is relevant with the smooth section 24 and the length of internal lining pipe 1 in its inner steel anchor 2 that inserts.The crimping of cone transition zone 36 being carried out 33,34,35 3 positions of crimping and some mark is the same; make water conservancy diversion sleeve pipe 3 be securely fixed in lead 4 conduction strand layer 41 around; the effect of cone transition zone 36 is to form the paratonia district; make stress distribution even; unstressed centrostigma shields to the lead mounting points.
Fig. 5 is the cutting schematic diagram after the supporting gold utensil assembling of the terminal crimping.Represented on water conservancy diversion sleeve pipe 3 and lead 4 and the steel anchor 2 crimping form on the annular burr 23 among the figure.By to the crimping of the gauge point 34 of water conservancy diversion sleeve pipe 3, make steel anchor 2 annular burrs 23 become the burr surface of reversed arrangement to be crimped onto mutually with terminal type water conservancy diversion sleeve pipe 3 is inner to gauge point 33 places; Gauge point 35 is to the crimping between the termination 30, makes that the conduction strand layer 41 of lead 4 is tight to be electrically connected and mechanical connection with 3 realizations of water conservancy diversion sleeve pipe, can transmit the electric current from lead.
The composite core aerial condutor should be able to bear installation, maintenance and the relevant load that may occur in service with the design of the supporting gold utensil of terminal, and can bear the various tests of design work electric current, working temperature and environmental condition.
