Automotive Wire Harness Industry Standards Need to be Introduced Urgently

  1. 1. Automotive Wire Harness Industry Standards Need to beIntroduced UrgentlyAutomotive wiring harness welding process starts to attract increasing attentionWith the rapid expansion of the scale of Chinas automotive industry in recent years,supporting industries associated with the automotive industry chain have obtained the marketspace for simultaneous development, such as doubled automotive wiring harness demandbrought by automobile production significant increase, while automotive wiring harnesswelding process starts to attract increasing attention. Automotive wiring harness is regardedas car "vascular”, which is generally considered to be the central nervous system of a car,connecting related functions of on-board computers and vehicles together. The automotivewire harness content and number in vehicle electronic technology has gradually become animportant indicator to evaluate the performance of the car.Comparison between two welding production processes of automotive wiring harnessIt is understood that the current welding production process of automotive wiring harness ismainly available for crimping and ultrasonic welding two kinds: crimping is to use theterminals toe press multi-strand wires together to form a connector; the ultrasonic welding isto use physical effects arising from ultrasonic vibration to combine the thrum. Ultrasonicapplied to the production of automotive wiring harness welding earliest became popular inEurope and the United States, which is mainly due to the development of foreign ultrasonicmetal welding technology. Comparatively, crimping is fast to produce, simple equipment, lowcost, but there is the metal stamping rebound risk, and has the risk of oxidation and rust inharsh conditions, all of these risks can lead to poor contact. The initial investment ofultrasonic welding equipment is higher, but these risks of crimping do not exist in ultrasonicwelding, and harness resistance welded by ultrasonic is very low, which is basically close tozero. Industry experts said that ultrasonic welding will become the mainstream of futureautomotive wiring harness welding process with excellent production efficiency and productperformance and other advantages.Ultrasonic harness welding specifications need to be introduced as early as possibleCurrently, the entire domestic ultrasonic welding automotive wiring harness product quality isgood and bad, and there are even a lot of shoddy products deceive real ones on the market.Some wiring harness manufacturer uses circuits and transducers of the existing ultrasonicplastic welding technology to do ultrasonic metal welding equipment, which simply cannotmeet the technical requirements of the automotive wiring harness mass-production. It isbecause of the lack of uniform standards and regulation, there are many non-standard, unfaircompetition domestic ultrasonic harness welding market, which to some extent limits andhampers the healthy and orderly development of the industry. Many people in the industryagree that as the mainstream automotive wiring harness welding process in the future, the
  2. 2. market potential of the ultrasonic welding is huge. Hope the national and industryassociations introduce ultrasonic harness welding specifications as early as possible.www.china-wireharness.com is a private medium-Sized enterprise, offers a wide range ofwires and cables, including wire harness/wiring harness, USB cable, HDMI cable, flat cable,ribbon cable and so on.This article is come from:http://www.storage-battery.com/index.php/automotive-wire-harness-industry-standards-need-to-be-introduced-urgently.htm
