3. 0.13mm2 wire machine mechanical strength

Compared with a pure copper wire of 0.35mm2, the tensile strength of the CUSN alloy wire is 110N, the stretching strength is about 620N/mm2, and the tensile strength of the CUMG alloy wire is 118N, the stretching strength is about 670N/mm2, 0.35mm2 The tensile strength of the pure copper wire is only 75N, and the stretching strength is about 670N/mm2. It is obvious that the mechanical strength of the alloy wire is significantly better than the pure copper wire.

In terms of bending testing, the performance of CUSN and CUMG alloy wires is also better than pure copper wires with 0.35mm2, as shown in Figure 2.

In the application of the vehicle, because there are many vibration areas, such as the door hinge area, the engine compartment vibration area, etc., in 2013, a small SUV cable fracture accident occurred in 2013. Plastic skin at the front door of the left front door line hinge is cracking N, a break (a fracture is completely connected after the cable is completely connected). The vibration area will undoubtedly affect the performance of the wire beam, especially if it is broken in high temperature environments; in extreme low temperature environments, the wire beam will also break due to the frozen ice crystal freezing.

For the reliability of the alloy wire of 0.13mm2 in the high temperature environment and the use of the vibration area, it is recommended to perform vibration experiments and sports car experiments at the sample stage to verify whether the wire is safe.

Fourth, 0.13mm2 alloy wire processing process

The number of copper wires at 0.13mm2 alloy wires is consistent with the wires of 0.35mm2, but because of the difference in wire diameter, the single copper wire diameter of the 0.13mm2 alloy wire will be much smaller, so there is a very high high on the wire peeling wire and the end of the terminal. It is required that when artificially stripping lines or equipment, the phenomenon of cutting copper wire is very easy to occur, which will lead to unqualified terminal pressure. If luck flows into the market, it will cause problems such as unstable functional function or failure. Therefore, the 0.13mm2 alloy wire is absolutely not allowed to break the problem of single copper wire. The beam supplier must have detection methods during the production stage. At present, there is a capacitor header in the automatic opening and automatic pressure connection device provided by Komax to detect the disconnection. The disconnection section detected during the device operation process will automatically cut off a certain length of the wire, and then continue to peel the lines and continue Pressoring, this not only guarantees the quality of the wire, and the equipment can still run normally.
