Description

Technical Field

[0001] The utility model relates to the field of detection technology, in particular to a pressure mechanism and a detection device. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. Two magnetic core columns and two crossbeams can be combined to form a soft magnetic product. The magnetic core columns and crossbeams form a magnetic circuit. Since two different magnetic core columns cannot have absolutely consistent heights when manufactured, there must be a height difference between the two magnetic core columns. As a result, when the two core columns and crossbeams are combined to form a magnetic circuit, there is a gap between the end face of the magnetic core column and the plane of the crossbeam. The size of the gap will affect the results of inductance testing of soft magnetic products.

[0003] In the prior art, inductance detection of soft magnetic products is performed manually. However, this method will generate additional labor costs; in addition, during the process of manual inductance detection of soft magnetic products, the crossbeam is pressed by hand to reduce the gap between the magnetic core column and the crossbeam. The result of inductance detection is affected by subjective factors of manual labor and is not accurate and objective. Utility Model Content
