Description
Technical field
It is fast more particularly to a kind of medium and high voltage cable conductor the present invention relates to electric wire manufacture new technology operating method
Quick access head technique.
Background technology
In the production process of crosslinking core, due to technological parameter, the restriction of the mode of production, manufacturing expense, friendship is determined
Online group must use quantity-produced mode.At present, crosslinking conductor tab has two kinds by the way of：The first is resistance pair
Weldering, second is that silver solder welds.First way puts into larger in advance, needs about 100,000 yuan of procuring equipment；Second of welding side
Formula general consumption is larger, need to use acetylene and oxygen that silver solder is merged into welding with both ends copper conductor every time, and often welding a head needs
About 50 yuan of silver solder cost, while it is also required to an oil pressure pump and heading machine, different size crimp.Both the above joint side
The enterprise's production cost that formula results in is too high.
The content of the invention
In order to solve the above problems, the present invention proposes a kind of new conductor tab technique, i.e., using conductor delamination steel
Pipe crimps, and strength of joint is firm, processing is simple, and cost consumption significantly reduces compared with above two mode, every joint steel pipe
Only need 5 yuan.
To realize object above, using following technical scheme：Medium and high voltage cable conductor snap joint technique, using conductor point
Layer peels off steel pipe crimping mode, and processing step is as follows；
1）Select joint steel pipe：Joint steel pipe material is 45# steel, and shape of threads, tapped bore are processed into inside joint steel pipe
Identical with that need to crimp conductor internal layer diameter, to increase the snap-in force of junction block and conductor, the length of joint steel pipe is 50-65mm,
The pitch * depths of thread=1*1mm；
2）Conductor is handled before crimping：Need the outermost layer of tip side conductor to be tightly wrapped with heat resistant adhesive tape, then peel off conductor outermost
Layer, the length peeled off is 70-80mm, leaves behind conductor internal layer, and outermost layer conductor section is polished into 45 degree of slopes with file
Mouthful；
3）Coupling compression joint：Step 2）Two after processing need joint conductor internal layer to be inserted in joint from joint steel pipe both ends respectively
After steel pipe, joint steel pipe is placed in the mould of heading machine, crimp into it is hexagonal, then with file by joint steel pipe polish justify
It is sliding；
4）Connect post processing：Whole joint is wound into plastics heat resistant adhesive tape, the external diameter after winding should be led with unstripped original
External footpath differs 0-1mm.
Beneficial effect of the present invention：
1st, compared with upset butt welding mode, infusion of financial resources is few.One conductor resistance butt welding machine need to be ten tens of thousands of yuan, and this kind of side
Formula need to purchase oil pump, heading machine and related die, only need 1.5 ten thousand yuan, input cost reduces 10 times.
2nd, compared with silver solder welding manner, each joint saves expense 90%, and strength of joint is firm, and technique is simple.

Embodiment
Embodiment
The joint process method is further illustrated with reference to accompanying drawing, now determines conductor I（2）With conductor II（3）To need joint
Conductor.
1）According to crosslinking conductor specification, joint steel pipe is determined（1）Tapped bore, wall thickness and length, for details see attached table.
2）Selection material is 45# steel as joint steel pipe（1）, joint steel pipe（1）It is processed into shape of threads, tapped bore in inside
It is identical with conductor internal layer diameter need to be crimped, the pitch * depths of thread=1*1mm.
3）Conductor I（2）With conductor II（3）The outermost layer heat resistant adhesive tape of tip side（4）Tightly wrapping prevents that conductor is loose, then shells
From falling conductor I（2）With conductor II（3）Outermost layer, conductor internal layer is left behind, and outermost layer conductor section is polished into 45 with file
Spend groove；If conductor diameter is bigger, joint steel pipe（1）Length capping 60mm.
4）Conductor I after stripping（2）With conductor II（3）Respectively from joint steel pipe（1）After joint steel pipe is inserted at both ends, it will connect
Head steel pipe（1）It is placed in the mould of heading machine, crimps into hexagonal, joint steel pipe（1）With conductor I（2）With conductor II（3）Pressure
Consolidation is connect again with file by joint steel pipe（1）Polish round and smooth.
5）Whole joint is wound into heat resistant adhesive tape（4）, external diameter should maintain an equal level with former conductor diameter after winding or smaller 1mm is
Can.
