Portion is cased with aluminum pipe and is connected to copper coin by friction welding (FW), and the copper coin is equipped with special-shaped terminal, between the copper coin and special-shaped terminal
It is connected by solder.
Preferably, the solder is Kufil.
Preferably, the copper coin and special-shaped terminal outer are equipped with heat-shrink tube.
A kind of resistance brazing formula harness processing technology, includes the following steps：
S1：Wire rod press, take the aluminum steel of certain length, process aluminum steel end burst at the seams stripping head, insulating layer is shelled
From the aluminum steel of stripping insulation layer being stretched in aluminum pipe, and be put into pressing in pressing mold, ensures pressing
Section is circle；
S2：It is put into cutting machine to aluminum steel to cut, ensures that end face is smooth；
S3：Aluminum steel is fixed on fixture by friction welding, and copper coin is fixed on high-speed rotating stationary fixture,
The smooth one end of aluminum steel is directed toward to the end of copper coin, the two fitting, copper coin is driven high speed rotation, simultaneously
Aluminum steel is pressed on copper tip so that copper tip is combined with aluminum steel, the upper copper coin of welding at the both ends of aluminum steel；
S4：Special-shaped terminal is positioned on copper coin by resistance brazing, and solder is positioned over copper coin and special-shaped terminal weight
Folded position, provides energy by way of resistance welding so that liquid solder moistens copper coin, fills copper coin
With the gap between special-shaped terminal, welding is realized；
S5：Welding section is carried out tight by pyrocondensation using twolayer firing shrinkage tube.
Resistance brazing formula harness proposed by the present invention and its preparation process have following advantageous effect：Soldering processes are used than mother
The low-melting metal material of material is less than base material melt temperature, profit as solder by weldment and solder heat to brazing filler metal fusing point is higher than
Base material is soaked with liquid solder, fill play movement and realizes the connection of terminal and conducting wire, brazing deformation with base material phase counterdiffusion
Small, connector smooth and beautiful appearance, by resistance brazing, the copper wire and terminal of welding section, it is one that subregion, which realizes molecule diffusion to melt,
Body, rest part are filled up completely by solder, the seamless connection of aluminum steel-copper coin-abnormity terminal are ensure that, so as to avoid bonding pad
Domain electrical property relaxation phenomenon caused by by air oxidation.
