Description
Technical field
The present invention relates to automobile connecting line welding field, especially relate to a kind of aluminum steel bundle ultrasonic welding process and weldering thereof
Connecting terminal.
Background technology
Orthodox car wire harness is mainly realized conducting with copper cash by crimping (surface contacts) mode by solder terminal and connects.
Between copper wire, having slight gap between copper wire and terminal, connecting portion is to have certain resistance (much larger than material electricity itself
Resistance), easily loosen along with crimping position after vehicle-mounted vibration and long-term ageing, aoxidize, thus cause loose contact, have wire harness local to send out
The heat even risk of ablation.
Copper material cable has sufficient codes and standards in manufacture and application.But the price of its 4 times of aluminum and resource
Scarcity, is the basic of restriction China copper cable industry sustainable development.On the premise of meeting equal electric property, aluminium alloy
The weight of cable is the half of copper core cable, and its diameter is about 1.1 to 1.2 times of copper core cable, and price is than traditional copper core electricity
Cable low by 10% to 20% (some enterprise claims 30% to 50%).
Automotive wire bundle weight accounts for the 1～2% of vehicle weight.According to statistics, the wire harness usage amount of a battle wagon reaches
2km, weight is 20～30kg.Automobile often travels the wire harness consumed energy about 50W of 100km, 25kg weight, is equivalent to the 0.1kg that burns
Fuel oil.Research shows, if vehicle complete vehicle weight reduction 10%, fuel oil consumption can reduce by 8%；Car weight often alleviates 100kg, and hundred is public
In oil consumption can reduce by 0.3～0.6L, CO2 discharge capacity can reduce about 5g/km.
Due to the feature of aluminum steel own, easily there is electrochemical corrosion, be easily formed oxide layer and cause contact site to be led in the contact of copper aluminum
The most not enough, under mechanical load, easily there is creep in relatively copper.If therefore using traditional copper-copper compression joint technique is to protect
The reliability of barrier copper-aluminum steel bundle, this just utilization to aluminum steel bundle bring challenge.
Summary of the invention
For solving the problems of the prior art, the present invention proposes a kind of aluminum steel bundle ultrasonic welding process, including following
Step:
S1: carrying out the welding region of solder terminal aluminizing processes or do not electroplate, and remainder is tin plating, and by welding ends
Son is fixed on the fixture of ultrasonic welding machine, the opening upwards of described solder terminal；
S2: take aluminum steel head peeling, make wire rod expose, aluminum steel head is positioned over the weld zone of terminal, and non-skinner is sticked in
The opening part of solder terminal, starts ultrasonic welding machine, and aluminum steel head and terminal are compressed by the soldering tip of ultrasonic welding machine, produce simultaneously
Raw dither realizes the high frequency friction of aluminum steel and terminal, and realizes the fusion of copper aluminum by fricative heat itself.
Preferably, realize terminal openings structure while pressing under described soldering tip to be compressed at conductor insulation sheath position.
Preferably, the weld zone cuff glue heat-shrink tube of described solder terminal carries out encapsulation process.
A kind of solder terminal, including weld part, described weld part is provided with hatch frame, and described hatch frame includes being positioned at
The leg of described weld part both sides, described leg side is provided with inclined-plane, and the inclined-plane between two is towards setting.
The aluminum steel bundle ultrasonic welding process that the present invention proposes has a following beneficial effect:
1. achieve directly being reliably connected, including electrical property and mechanical performance of solder terminal and aluminum steel.
2. alleviate wire harness weight, be particularly suitable for the application of longer relatively thick bundle, such as electromotor front deck to boot or the end
Big square of wire harness of dish.
3., because connecting wire to use aluminum steel, price relatively copper cash is cheaply a lot, can effectively reduce wire harness cost, from
And reduce integral vehicle cost.
4, realize fixing aluminum steel in solder terminal while welding, increase work efficiency.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make
Accompanying drawing be briefly described.
Fig. 1 is the solder terminal side schematic view of the present invention；
Fig. 2 is the solder terminal top view of the present invention；
Wherein, 1-welding region, 2-solder terminal, 3-hatch frame, 4-inclined-plane.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.
As shown in Figure 1 and Figure 2, the present invention proposes a kind of aluminum steel bundle ultrasonic welding process, comprises the following steps:
S1: carrying out the welding region 1 of solder terminal 2 aluminizing processes or do not electroplate, and remainder is tin plating, and will welding
Terminal 2 is fixed on the fixture of ultrasonic welding machine, the opening upwards of described solder terminal 2；
S2: take aluminum steel head peeling, make wire rod expose, aluminum steel head is positioned over the weld zone of terminal, and non-skinner is sticked in
