Sockets are essential for every family. However, unqualified outlets will bring huge security risks. On April 3, the press conference held by the Jiangsu Provincial Bureau of Quality Supervision announced on the extension cord outlets. The latest spot check showed that about 20% of the failure rate.
The extension cord socket is commonly known as 'Patchboard' and is a national compulsory certification product. It is suitable for occasional and short-term electricity demand. The production company is mainly concentrated in Guangdong, Zhejiang, Jiangsu and other provinces. About 12 companies are located in Nanjing and Suzhou.
Spot checks found that the quality of the patch panels on the provincial market was not high. The spot checks of the product were 40 batches and 33 batches were qualified. The qualification rate was 82.5%. Among them, 9 batches of Jiangsu enterprises' products were checked, and 8 batches were qualified. The rate is 88.9%.
Xu Xiaoang, deputy director of the Provincial Electrical Product Monitoring Center, told reporters that the unqualified items of the spot check results were concentrated on the signs, dimensional inspections, structure of extension cord sockets, insulation resistance and electrical strength, soft cables and their connections, heat resistance, Creepage distances, clearances, and distances through sealants. For example, spot checks found that the soft cables of the two batches of products and their connections were unqualified. The grounding conductors did not use the yellow-green line in accordance with national standards.
Spot checks revealed that the cross-sectional area of the YIJIA extension cord socket produced by Jining Yiyi Electric Appliance Co., Ltd. was not configured in accordance with the standard, and there was a case of cutting corners and materials; Puning City occupied the 'Kangjiafu' brand produced by Yu Xubin Electric Parts Factory, and Jining. The 'YIJIA' brand extension cord socket produced by Shanghai Yiyi Electric Appliance Co., Ltd. does not have a protective door. It is marked as the 'Chiwei' brand extension cord socket produced by Jiri Electric Appliance Factory of Puning City, Guangdong Province. The product's insulation resistance and electric strength are unqualified. Insulation is broken down at high voltage.
It is understood that the extension cord socket products produced after April 14, 2017 must obtain the CCC compulsory certification and must be equipped with protective doors. Xu Xiaoang reminds: 'The power strip must be used nearby, and the power cord should not be too long. It is not appropriate to use it. Too long wire coils or bundles should be spread out as far as possible; can not overload the use of patch panels, while using more electrical appliances, should choose products with overload protection. '
In addition to spot checks on extension cords, the quality inspection also involved switch panels, routers, and other products. How to select the switch panel? The more antennas there are on the router, the larger the signal? The quality assurance experts at the press conference To this solution.
The switch panel belongs to the national compulsory certification product. This time a total of 74 batches of products were checked, and 68 batches were qualified. The pass rate was 91.9%. Among them, 37 batches of Jiangsu enterprises' products were checked, 36 batches were qualified, and the pass rate was 97.2%. The unqualified project focused on two indicators of normal operation and signage. Liu Weijia, head of the provincial quality inspection and testing department, said that spot checks found that the normal operation items of the three batches of products were unqualified, the switch operation, the static contacts, and the spring material quality were poor. In use, problems such as high-temperature melting or deformation after repeated use are liable to occur. In addition, product marking items are not qualified, and model, standard number, manufacturer or seller information is not marked on the switch panel.
Quality inspectors introduced that when the consumer purchases, in addition to looking at the 'CCC' logo, there is also a small trick to listen to the sound of the switch. If the seesaw operates flexibly, the sound is crisp, indicating that the terminals should be made of copper or copper alloys And can be firmly fixed. This switch panel quality should be good.
For the quality inspection of the routers, a total of 34 batches of products were spot-checked, and the pass rate was 88.2%. The spot check results showed that the unqualified projects focused on radiation disturbance, power terminal conducted disturbance voltage, clearance and creepage distance, electrical strength, marking and Explain 5 indicators. The “LB-LINK” brand dual-band router manufactured by Shenzhen Bilian Electronics Co., Ltd., the maximum quasi-peak radiated disturbance measured, 4 times the supranational standard limit.
Some consumers often think that the bigger the router or the more antennas carried on it, the better the signal. In fact, this is a misunderstanding. Huang Jin, Minister of Inspection Department of Taizhou Product Quality Supervision and Inspection Department reminded: Look for products with CCC certification mark, signal strength depends on router transmit power, transmission technology and the number of antennas with a reasonable mix, do not blindly pursue the number of antennas.
