Description

Technical Field

[0001] This utility model relates to the field of voltage measurement technology, and more specifically, to a voltage test clip. Background Technology

[0002] Voltage refers to the work done by an electric field force on a unit positive charge moving from one point to another in an electric field. Voltage measurement is an important part of electronic circuit measurement and is the foundation of many electrical parameter measurements. When measuring the voltage of electrical equipment or other instruments, a voltmeter or multimeter is generally connected to the equipment to measure the voltage. The connection is typically made using a connecting wire and clip extended from the voltmeter to the circuit on the equipment. However, existing voltage test clips have a relatively simple structure, made entirely of metal with an insulating sleeve around the handle for easy operation. However, the large exposed metal area makes them prone to contact with external cables, potentially causing short circuits and safety hazards. Furthermore, the clamping effect of existing test clips is generally poor, making them prone to detachment. The existing test clips are directly fixed to the connecting wires by soldering, making it difficult to quickly replace damaged wires. Utility Model Content
