Extension cable sockets, also known as wire extension components, commonly known as patch panels, are widely used in homes, offices, and other places. The safety of product design directly affects the safety of the lives and property of consumers. There are many items to assess the safety of extension cord socket products, such as anti electric shock protection, structure, creepage distance, electrical clearance, temperature rise, pull-out force, and so on. In the 2021 random inspection plan, it includes household and similar purpose plug and socket products (hereinafter referred to as "plug and socket"). In recent years, plug and socket products (including multi-functional socket products with power adapters) have almost been included in the national supervision random inspection plan every year, highlighting the importance of quality and safety of plug and socket products! Extension cord sockets shall be tested according to the standard GB/T 2099.1-2008 Plugs and Sockets for Household and Similar Purposes - Part 1: General Requirements; GB/T 2099.3-2015 Plugs and Sockets for Household and Similar Purposes - Part 2-5: Special Requirements for Converters; GB/T 2099.7-2015 Plugs and Sockets for Household and Similar Purposes - Part 2-7: Special Requirements for Extension Cord Sockets; GB/T 1002-2008 Single phase plugs and sockets for household and similar purposes - Types, basic parameters and dimensions; GB/T 2099.1 and IEC 60884-1 "Plugs and Sockets for Household and Similar Purposes - Part 1: General Requirements"; GB/T 2099.7 and IEC 60884-2-7 "Plugs and Sockets for Household and Similar Purposes - Part 2-7: Special Requirements for Extension Cord Sockets". The standard applies to extension cord sockets for indoor or outdoor use, household and similar purposes, detachable and non detachable, with or without grounding contacts, rated voltage above 50V but not exceeding 440V, and rated current not exceeding 16A.
