How do you do the identification of electronic harnesses?

Electronic wire and cable products are closely related to people's lives, so the quality is directly related to the personal and wealth safety of the vast number of consumers. Therefore, the correct purchase of electronic wiring harness cables can be well identified. Suzhou Huichengyuan Electronics Co., Ltd. provides you with the following knowledge: 1. Check the "CCC" certification mark. Electronic wire and cable products are national compulsory safety certification products, all production enterprises must obtain the "CCC" certification certified by the Electrical Product Certification Committee, and there is a "CCC" certification mark on the pass certificate or product. 2. Look at the inspection story. Electronic cables, as products that disturb personal and wealth security, have always been listed as the focus of monitoring and testing by the authorities, and regular manufacturers take over the testing of monitoring units periodically. Therefore, the seller should be able to have a quality inspection unit's inspection instructions, otherwise, the quality of electronic wire and cable production will lack a basis. 3. Look at the packaging. The electronic wiring harness cable produced by regular enterprises whose products meet the national standards is very careful about product packaging. When choosing and purchasing, be careful that the packaging is wonderful, the printing is clear, the model specifications, the factory name and the factory address are complete. 4. Look at the outside. The surface of the product is smooth and round, and the color is even. Electronic wiring harness and cable enterprises whose products meet the national standard conditions, in order to improve the quality of products and ensure that the products meet the national standard conditions, strictly control the selection of raw materials, production equipment, production technology and other aspects. Therefore, the surface of the electronic wiring harness and cable products produced meets the scale conditions, smooth and round, and the color is average. The surface of fake and inferior products is rough and dull. For rubber insulated flexible cables, the surface is round, the sheath, insulation and conductor are tight and not easy to peel off. Fake and inferior products have rough surface, large ovality and low insulation strength of sheath, which can be torn by hand.

5.Look at the conductor. The conductor is shiny, and the DC resistance and conductor layout size meet the national scale conditions. Electronic wire and cable products that meet the national standard conditions, whether they are aluminum or copper conductors, are relatively bright and oil-free, so the DC resistance of the conductor fully meets the national standard, with excellent conductivity and high safety. 6.Measure the length of the electronic harness cable. Length is an important and intuitive way to distinguish and meet the national standards to reduce counterfeit and inferior products. When choosing and purchasing, do not attempt to be cheap. If the actual number of meters is lower than the nominal number of meters, the length of the electronic cable must be consistent with the nominal number of meters. The state stipulates that the allowable error per 100 meters is ± 0.5 meters.
