With plug-in USB sampling 4 percent unqualified! Op, Philips ... ... these brands on the blacklist!
Technology is evolving and our lives are progressing, and this progress is reflected in the bits and pieces around us, which, for example, have changed from the traditional style to the built-in USB interface, a small change that has brought life Many convenient, but the relevant departments of the test found that this new and convenient plug-in board, but there are some hidden dangers.
Shanghai Quality Supervision Department spot checks 20 batches of products passing rate just over half
Recently, the Shanghai Bureau of Quality Supervision for the Shanghai production, sales and e-commerce platform for sale with a USB interface, power adapter (patch panel) conducted a quality control spot checks of the total of 20 batches with a USB interface, the power adapter product.
Test found that there are 8 batches of products there are different unqualified items, the overall pass rate of 60% or so.Researchers said that it reached barely pass the level.
The reporter learned from the CNCA that since the implementation of the CCC certification system in 2001, China has explicitly included the power adapters for audio and video equipment and information technology equipment, including the USB interface power adapter, into the scope of CCC certification. , The plug-in board with USB interface must be compulsory product certification, and marked the certification mark, before the factory, sales, import or use in other business activities.
So, as a need for compulsory certification of products, the passing rate of just over half?
Power adapter with USB interface ≠ USB interface + patch panel
Detector told reporters that with a USB interface, the power adapter is not a common sense of the USB interface and plug the board combination.Plug board belongs to the primary circuit, the voltage is 220V, and the other end of the USB interface directly connected with the phone, Belonging to the secondary circuit, the voltage should be less than or equal to 5V.
To fight pressure is one of the sampling project, that is, after the sample wet heat treatment of the electric strength of the project sampling the project failed two products, namely:
1, nominal Cixi Qingfeng Electronics Co., Ltd. produced the Qingfeng brand QF-308K four with a switch USB converter 1.8 meters;
2, the OPPLE brand OPPLE switchboard nominal Op lighting Electric (Zhongshan) Co., Ltd. three five holes three USB 1.8 meters.
The 8 unqualified samples of this test all have the same unqualified items, that is, the clearance, creepage distance and insulation penetration distance of this project.Experts said that this may cause users to use these patch panels to charge the phone Will be exposed to 220V high pressure.
The eight unqualified products were:
1, nominal Cixi Qingfeng Electronics Co., Ltd. produced the Qingfeng brand QF-308K four with a switch USB converter 1.8 meters;
2, the nominal Guangzhou Hao Electronics Co., Ltd. production PHILIPS Philips extension cable outlet;
3, Nominal Op Electric Lighting (Zhongshan) Co., Ltd. OPPLE card licensing three switch three five holes three USB 1.8 m;
4, nominal Mani Electric Industrial Co., Ltd. Shenzhen, many license 9 heavy safety outlet;
5, Nominal Shenzhen Yuan Chong Times Technology Co., Ltd. produced ORICO desktop USB smart digital power supply terminal board;
6, Nominal Link Technologies Group Co., Ltd. through the production of the leading anti-electric shock safety socket;
7, the nominal Woke Sound (Shanghai) Co., Ltd. production PHILIPS Philips power converter;
8, nominal Intelman (Changzhou) Co., Ltd. production of Intel Man USB power converter.
Shanghai Institute of Quality Supervision, Inspection and Technical Institute of electrical and household appliances inspection Tang Yanyan:
For example, consumers are using their mobile phones while charging their cell phones, and then the cell phone is electrocuted. The reason for this is that the clearance has not reached the limit or is not big enough.
Shanghai Regulatory authorities: Involving enterprises to rectify product recall assessment has been launched
Relevant person in charge of supervision said that as the substandard items of this sampling are all items related to electrical safety, there is a huge potential safety hazard. Therefore, in addition to making the necessary rectification, the enterprises may face administrative penalties Shanghai Bureau of Quality Supervision also started recall evaluation for some enterprises.
Zhou Jia, Deputy Researcher, Product Quality Supervision Department, Shanghai Bureau of Quality Supervision: For the defective products, the enterprise can eliminate the potential safety hazard through the form of voluntary recall.If the enterprise can not perform the voluntary recall, then we can also use the method of mandatory recall, Will have been transferred to the hands of consumers, there may be some risk of defective product recall, thus eliminating potential safety problems.
