Problems solved by technology

In the above method, every time a product is tested, it needs to be wound with a corresponding number of turns, and the wire needs to be removed after the test, which cannot realize automatic operation, greatly wastes copper wires, and leads to low efficiency. When the number of products is large, it is even impossible to realize Full inspection, often defective products flow out

Abstract

The invention provides a soft magnetic circular product inductance test method. The method comprises steps that a magnetic ring is firstly fixed, a first signal connection point of an upper tool and a second signal connection point of a lower tool are plugged in a hollow region of the magnetic ring, the first signal connection point and the second signal connection point are enabled to realize electric conduction, electric signal conduction is realized, the inductance value of the magnetic ring is detected, so mass-scale tests on magnetic rings are convenient, compared with a mode in the prior art requiring corresponding loops of winding for each product test and uncoiling operation after the end of the test, the soft magnetic circular product inductance test method improves production efficiency, avoids copper wire waste and greatly saves cost.

Description

technical field [0001] The invention relates to a method for testing inductance, in particular to a method for testing the inductance of a soft magnetic circular product. Background technique [0002] A magnetic ring test method currently used in the market is as follows. First, a magnetic ring is provided, and the magnetic ring is in the shape of a closed ring, and then a wire is provided, and the wire (copper wire) is wound around the magnetic ring. On the surface of the ring, a multi-turn coil is formed on the surface of the magnetic ring, and then the wire is energized for testing. In the above method, every time a product is tested, it needs to be wound with a corresponding number of turns, and the wire needs to be removed after the test, which cannot realize automatic operation, greatly wastes copper wires, and leads to low efficiency. When the number of products is large, it is even impossible to realize Full inspection, often defective products flow out. Contents ...
