Description

Technical Field

[0002] Voltage, also known as potential difference or electric potential difference, is a physical quantity that measures the energy difference caused by different electric potentials of unit charges in an electrostatic field. In some electrical appliances, for safety reasons, it is necessary to frequently use a voltage tester to detect the voltage of the electrical appliances. A voltage tester is an instrument for measuring voltage. A voltage tester is a large resistor.

[0003] In the existing technical scheme, a publication number: CN111781414A is proposed, which is a DC digital current test instrument, including a lower fixed frame, a tester and an upper fixed frame, the surface of the tester is movably connected to the inner cavity of the upper fixed frame and the lower fixed frame respectively, the inner cavity of the lower fixed frame is movably connected with a receiving block, one side of the receiving block passes through the surface of the lower fixed frame and extends to the inner cavity of the lower fixed frame, the inner cavity of the lower fixed frame is provided with a sliding groove slidably connected to the surface of the receiving block, and the bottom of the receiving block is fixedly connected to a first spring.

[0004] In order to solve the problem that the internal electronic components are easily damaged by the impact of external forces during transportation and movement, the existing technology uses the surface of the clamping block to be clamped with the inner cavity of the clamping slot through interference fit. When it needs to be moved, the box cover is flipped over, and the clamping block is clamped into the clamping slot to cover the tester. The screen of the tester can be blocked to prevent damage caused by impact during movement. However, the internal protection of the electrical test instrument is poor. When the staff accidentally falls, it is easy to cause damage to the internal parts of the equipment, which in turn causes the equipment to be unable to be used normally. Utility Model Content
