Description

Technical Field

[0001] This utility model relates to the field of sensor detection technology, and more specifically, to a high-precision current sensor rapid testing fixture. Background Technology

[0002] A current sensor is a device specifically designed to monitor changes in current. It has the ability to convert detected current information into a standard electrical signal or other form of information output according to specific rules. This conversion process ensures that the information can be effectively utilized in multiple stages, including transmission, processing, storage, display, recording, and control.

[0003] Nevertheless, many current clamping mechanisms have certain design limitations. The clamping force and travel distance of these mechanisms are usually fixed, making them difficult to adapt to the needs of workpieces of different sizes. Specifically, when encountering large workpieces that exceed design specifications, using such clamping mechanisms may cause damage to the workpiece; conversely, if the workpiece is small, it may not be able to be securely held. Furthermore, in testing environments requiring high-precision operation, existing positioning devices are not only insufficiently accurate but also lack sufficient travel speed to meet the demands of efficient operation.
