Description

Technical Field

[0001] The utility model relates to a socket tester, belonging to the technical field of electrical safety detection instrument connection. Background Art

[0002] With the increasing number of electrical devices in modern homes and commercial environments, the demand for power sockets is also becoming increasingly diverse. In regular household use, 10A power sockets are the most common type, capable of meeting the power needs of most everyday household appliances. However, in some specific situations, such as when using high-power appliances or industrial equipment, the power capacity of 10A sockets is insufficient, and the higher-capacity 16A sockets are needed to meet the needs.

[0003] Traditional power outlet testers typically only test a single type of outlet, such as 10A or 16A outlets. This creates significant inconvenience in practical applications. For example, during home renovations or appliance repairs, it's often necessary to test different types of outlets to ensure their safety and functionality, a requirement that cannot be met with a single tester.

[0004] Furthermore, with the continuous upgrading and updating of electrical equipment, the compatibility and safety requirements for power sockets are becoming increasingly stringent. Traditional socket testers have shortcomings in terms of test accuracy, functional diversity, and ease of operation, making them difficult to meet the needs of modern users. Utility Model Content
