Standardization and standardization of extended harness

The problem of wiring harness connection to the terminals is one of the main causes of warranty and connector system failure. For automotive wiring systems, crimping is a very common method for attaching terminals to a wire harness. This process has proven to be reliable. Compared with the welding method, it is more economical and simple to operate in terms of improving the crimping reliability. To improve the terminal chuck geometry, connector manufacturers have put a lot of effort into it. Through a wide range of analytical and experimental studies, FCI not only developed a new analytical tool for crimp optimization, but also proposed a new innovative crimp geometry.

In order to record the process information of the designer's wiring harness and pipeline assembly planning, such as the assembly path, assembly sequence, auxiliary materials used, etc., in order to guide the assembly of the wiring harness and the pipeline components with the design results in the virtual environment, A wire harness assembly process model for cross-assembly based on routing tasks is used to organize and manage assembly planning process information of wire harnesses and pipelines in a hierarchical routing task chain.

Improve the consistency and maintainability of complex products and improve wire harness and pipe assembly processes. After the wiring harness and piping layout design is completed in the virtual environment, all the design information is stored in the model, and the model can be used as the basis for information exchange and transmission by various technicians, thereby improving product consistency and changing the current The current state of transmission of design information in physical analog quantities. In addition, the assembly process animation based on the assembly process planning results in the virtual environment can be used to guide the field workers to wire harness and pipeline assembly, thereby improving the standardization and maintainability of product assembly, while also effectively reducing leakage, Misassembly and other assembly quality problems occur.

Wire harnesses account for a large proportion of electromechanical products, such as in aerospace, aerospace, automotive, marine, household appliances and other fields. The main function of the wire harness is to reliably transmit the communication signal to ensure the normal communication between the electrical equipment. The importance of the wire harness is equivalent to the nerve of the human body; the main function of the pipeline is to stably and reliably transport the working medium such as gas, liquid and electricity to ensure the product. The ability to perform its function safely and reliably is equivalent to the blood vessels of the human body.

With the development of the information industry, especially the widespread application of large-scale integrated circuits, the miniaturization and high-energy of computers and other electrical appliances and electronic products require computer wires and wire harnesses with high reliability, good solderability, and small outer diameter. Therefore, the wire is required to be miniaturized, and such a wire must also be produced by an irradiation cross-linking process. The wires used on the aircraft require high heat resistance and high wear resistance to reduce the weight of the aircraft. The heat resistance and wear resistance of the irradiated cross-linked PE (main component) wire harness will be higher than that of the nylon wire used in the aircraft. The outer diameter of the wire is smaller than that of the nylon wire, if each large passenger aircraft needs This type of wire is 200km. Moreover, the wire has stable performance, high reliability and low price.
