In the wire harness processing, there are situations where multiple wires need to be connected. In the wire harness processing, conductor crimping and ultrasonic welding are often used to connect the wires. The length of the welding area and the conductor crimping area is about 2cm. The length of the loss here should be taken into account when calculating the size of the lower wire. Especially when there are multiple conductions, the influence on the length of the wire will become more and more important.
Wire routing within the harness
The wires in the harness have different directions, the simplest is a straight line without turning, and the loss of such length is the smallest. The more bends in the wire, the more the wire length is consumed at the bends, and the longer the overall lower wire length. Add extra slack for this type of wire to make sure it transitions smoothly from the bend.
