Has been worked out, is in the approval process, the earliest expected to be granted during the year. The new version of the Samsung , LG and other manufacturers will have a greater impact. Further to my cell phone charger standard YD/T1591 be incorporated into IT U standard, the standard has progressed. , "Now a new cell phone charger standard YD/T1591 (Second Edition) development has been completed, is in the approval process, the fastest is expected to be granted during the year." Ter laboratory director He Guili recently received " Communicate Industry Report "(Network) reporters said. Three types of interfaces coexist According to He Guili introduction, and in 2006 issued YD/T1591 (first edition) compared to, YD/T1591 (Second Edition) is a further major mobile phone charger mobile phone side of the interface standardization, proposed three criteria interface, "including MiniUSB, MircoUSB and 2mm cylindrical interface; addition further enhanced the Power supply Adapter performance, and expanded the scope of the standard not only for charging, but also for data transmission interface, not only for cell phones can also be used for other small Home Appliances And other ICT equipment. " To why use of the three interfaces as a standard interface, He Guili explained: first, through research, MiniUSB interface is currently on the market to use interface to form the largest proportion, the industry has good adaptability. Second, MircoUSB although lower rate, but its small size, high reliability, technological superiority, the trend has gradually replaced MiniUSB. Third, the use 2mm cylindrical interface, mainly on account of the standard universal power adapter required, in addition to other cell phones can also be used for other ICT products are widely used in power or charge. Universal mobile phone charger as standard definition of the original intention of not only reducing the duplication of purchase of mobile phone charger, but also for mobile phone chargers and other ICT products, charge / power supply common, other ICT products in order to reduce the number of power adapters. Other ICT products, many not apply to USB interface, and application of 2mm cylindrical interfaces. "In the long run, because MircoUSB replace MiniUSB is inevitable, so the future may be the natural transition to the two interfaces: MircoUSB and 2mm cylindrical interface." He Guili said. 's Investigation, the present greater impact by this standard cell phone brands will primarily Japanese and Korean brands. Because most other brand mobile phones have been used of the three interfaces, only Samsung, LG, Sony Ericsson And other cell phone manufacturers still use the original PIN-wire interface. "Although the implementation of this standard will affect the interests of some enterprises, but on society and the users but they are good but no harm, and is technically entirely feasible." He Guili said. The time has to upgrade 2006, China formally promulgated the cell phone charger standard YD/T1591 (first edition), due to the specific circumstances at that time, the first edition, only unified charging plug, and the interface between the cable, but cable The interface between the phone and did not make clear requirements. This has resulted in mobile phone charger mobile phone side interface is still diverse. "This is mainly because of the prevailing market conditions are very complex, cell phone charger is too messy, difficult standardization step. That is why we proposed a standardized step by step strategy: first unified power supply side of the interface, and unified phone side interface. To phone enterprise more buffer time to accept the new standard. "He Guili said," Now, the first edition of two and a half have been implemented, relatively effective, but also achieved the expected results. to implement the new standard the timing of the second edition has been basically mature resistance is also much smaller. " According to He Guili description, from the formal implementation of the standard 2007 to now, there are 6,000 varieties of handsets using the standard I am an expert from steelslittingmachine.com, while we provides the quality product, such as China aluminum slitting , China sheet metal slitter, slitting and rewinding machine,and more.
