Description

Technical Field

[0001] The utility model relates to the technical field of tungsten wire detection, in particular to a tungsten wire diameter limit detection mechanism. Background Art

[0002] Tungsten filament is a thin wire made by forging and drawing tungsten bars. It is mainly used in electric light sources such as incandescent lamps and halogen tungsten lamps. Most car lights are tungsten filament lamps. When testing car lights, it is usually necessary to use a continuity detection device to detect whether the tungsten filament inside the car light is continuous or disconnected. Therefore, a tungsten filament detection mechanism is needed to meet people's usage needs. When the current detection device detects the tungsten filament, the tungsten filament is clamped inside the crocodile clip, and then the continuity detection is performed through the detection box. However, the diameter of the tungsten filament is relatively small. When the crocodile clip is used to clamp the wire diameter, it is easy to cause unstable clamping and deviation, thereby affecting the continuity detection of the tungsten filament.
