What are the problems encountered in the processing of wire harness materials

Harness material processing time is divided into several processes, in the harness material processing time need to pay attention to some matters, otherwise it may lead to harness material quality problems, then the general time in the harness material processing process will present what kind of problems? 1. wear rubber shell line order is wrong: the rubber shell of the holes as small as three or four, as many as ten or twenty, the workers in the process of wearing the rubber shell non-stop long-term operation, and the number of holes is higher, it is very simple to inadvertently put the line in the wrong order. The number of holes is more, it is very simple not to pay attention to the order of the line inserted in the wrong order, originally to insert the line in this hole but inserted into the hole next to it. 2. cut the line is bad: in the process of cutting the line, often presents the cut is not neat, the copper line is damaged, in this regard, we should be in the boot before the different specifications of the wire to do the corresponding value of the knife to adjust the amount of mass production should be the appropriate amount of trial products. 3. playing the terminal (end pressure) presents bad: this process Generally the terminal hit the wrong location, the terminal is not completely wrapped around the copper wire, terminal over wrapping lead to inserted broken skin and so on the bad, these bad generally presented in the artificial hit the terminal operation, with automatic machine to hit the terminal, then only need to adjust the machine, presenting the chances of small harness for a certain load source group to provide service equipment as a whole, such as trunking lines, communication devices, control systems, and so on. The basic study of the theory of voice service is to study the relationship between the volume of voice service, call loss and harness capacity, therefore. Harness is an important fundamental concept in the theory of voice service. In modern cars, electronic control systems and wiring harness has a close relationship. Someone once played an image such as: microcomputer equivalent to the human brain, sensors equivalent to the sensory organs, the implementation of components equivalent to the movement of the tube, then the wiring harness is the nerves and blood vessels. Sedan wiring harness from the utility points, there are transport drive executive element (actuator) power line and the transmission of sensor input instruction signal line two kinds. The power line is a thick wire that carries a large current, and the signal line is a thin wire (optical fiber communication) that does not carry power. In the motor, the executive element with the wire cross-sectional area of 0.85, 1.25mm2, while the power circuit with the wire cross-sectional area of 2, 3, 5mm2; and special circuits (starter motors, alternators, engine grounding wire, etc.) are 8, 10, 15, 20mm2 different specifications. Wire selection, in addition to considering the electrical function, but also by the physical function of the vehicle when the constraints. For example, the rental car again and again open / close the door and across the body between the wire should be composed of good flexing function of the wire. In recent years, the use of electromagnetic shielded wires for tiny signal circuits has also been increasing.
