Description

Technical Field

[0001] The utility model relates to the technical field of electronic test instruments, and particularly relates to a combined tester for a voltage tester pen and a socket. Background Art

[0002] In the fields of electricians and maintenance, voltage tester pens and socket testers are indispensable tools. A voltage tester pen is mainly used to detect whether there is voltage in a circuit, while a socket tester focuses on checking the power-on status of a socket and whether the wiring is correct. However, most of these two tools on the market are independently designed, with relatively single functions and lack of integration. This separate design brings inconvenience in actual work. Users often need to carry both tools at the same time, which not only causes inconvenience in carrying but also increases the risk of tool loss or damage. At the same time, the existing socket testers lack protection, and the plug part is directly exposed, which is extremely easy to cause damage or harm to personnel.
