Do you know how to make wire harnesses? -- Classification of wiring harness three Jul 20, 2023

For example: air conditioning wire harness, water dispenser wire harness, computer internal power cord, coffee machine, egg beater and other signal cables, TV wire harness and other products that we can call home appliances wiring harness. Home appliance wiring harness is the main body of the network circuit without home appliance wiring harness there is no home appliance circuit. At present, whether it is senior luxury home appliances or economic ordinary home appliances, the form of wiring harness is basically the same, which is composed of wires, connectors and parcel tape. Home appliance wire is also known as low-voltage wire it is different from ordinary household wire. Ordinary household wires are copper single-core wires with a certain hardness. The home appliance wires are copper multi-core flexible wires, some soft wires as thin as hair several or even dozens of soft copper wires wrapped in plastic insulated tubes (polyvinyl chloride) soft and not easy to break. The common specifications of the wires in the home appliance wire harness are the nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeter wires, which each have the allowable load current value for different power electrical equipment with different specifications of wires.


Home appliance wiring harness is one of the lowest end products in the current wiring harness products, which is the simplest from the technical content and product supply chain, many factories have such supporting products.


Railway locomotive wiring harness: The product is mainly used in power system connection, (including the input and output of two-phase and three-phase power supply), communication system connection, (including the gating of new railway passenger cars, closed-circuit television, communication and telecommunications number connection) control system connection (the connection of railway electrical part control system) and the connection of internal electrical system.


With the acceleration of urbanization in China, the core technology of subway vehicle design and installation is also developing. According to the principles of the electrical wiring assembly process of subway vehicles, the specific technology of electrical wiring assembly of subway vehicles should be analyzed. In the electrical wiring assembly of subway vehicles, attention should be paid to ensuring that the counterweight of each car is basically the same, and the electrical wiring of each unit car is evenly distributed, so as to ensure the stability of subway vehicles while driving, and ensure the normal operation and use of the braking function of subway vehicles. To improve the service life and years of subway vehicles, the wiring harness requirements are very complex and have very detailed requirements on the wiring, and it is difficult for general enterprises to obtain the relevant product production qualifications.

Application classification of wind power cable assembly


Wind power connection cable: the product is mainly used in the connection of frequency conversion system, the connection of the control system in the cabinet; The link part inside the system is mainly the wind turbine blade, gear box and engine room and tower barrel. Since wind farms are mostly located in areas with harsh climatic conditions, the key of this product is the low-temperature torsional resistance of the cable and the flexibility of the cable at low temperatures. The cable should have excellent electrical and mechanical properties in the temperature of -50℃ ~ +80℃ environment.

Wind power "escape" is the key to connector selection, price is no longer the key factor in the selection of connectors, from cable to connector are industry brand materials.


Of course, the wiring harness will certainly not be as Aichi sorted out the few types, in general, the above types of wiring harness are the current mainstream products, the current wiring harness industry's overall learning ability is very strong, but the design and independent innovation ability is slightly insufficient, has not fully mastered the wiring harness processing and equipment design technology, There is no development mechanism for the organic combination of wiring harness and wiring harness equipment from products, materials, processes and equipment, and the future will usher in a turning point with the gradual expansion of the wiring harness market!


In recent years, the rapid development of electric vehicle manufacturing industry, and the popularization of 5G communication market, including the continuous development of household appliances in rural areas, have given the wiring harness market a good opportunity for development. This network hotspot supports the current development market prospects of wiring harnesses, because the development of many fields must use wiring harnesses. Therefore, the market demand for such products continues to rise, which is conducive to promoting the development of wire harness production equipment. For such products as wire harnesses, the market is increasingly demanding its quality and productivity. Some traditional manufacturers have long been unable to integrate into the development of this period, and the current automation technology, precision and efficient operation of the wire harness industry in the sustainable development, in the future development, the production and processing industry chain of the bundle may be independent innovation, and its manufacturers will carry out independent construction of the whole industry chain. The upgrading of the relevant industrial chain will produce stronger and higher quality products for a large number of customers. If you want to know more about the application of automation equipment in automation, save time and labor instead of labor.
