Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a multifunctional detection instrument for plugs and sockets. Background Art

[0002] Sockets, also known as power sockets and switch sockets. Sockets refer to seats that can be plugged with one or more circuit wiring, through which various wiring can be inserted. The connectors (Connectors) of general electronic products and the pins (Pins) of electrical appliances are called plugs. Household AC power plugs and sockets have male connectors that protrude in the shape of a rod or copper plate, which are physically inserted into female connector-type power sockets with slots or recesses.

[0003] Size is an important technical requirement that determines whether plugs, sockets and converters can be used safely and meet universal interchangeability requirements to avoid misinsertion. Unqualified size will affect user use or cause hidden dangers such as poor contact and misinsertion, which may damage the equipment at the least or cause fire and electric shock accidents at the worst.

[0004] The existing multifunctional testing instrument for plugs and sockets lacks a protective device. When the testing instrument body is not in use, dust is easily accumulated, and the backlight display screen is easily worn. In addition, the testing pen therein is inconvenient to store and is easy to lose. Therefore, we propose a multifunctional testing instrument for plugs and sockets. Utility Model Content
