Description
Technical field
The present invention relates to inductive technologies field, specifically a kind of epoxy I-shaped inductance manufacture craft.
Background technology
The direction that current power supply product is all high, small, light-weight towards frequency, power is high is developed, it is therefore desirable to subtract
The volume of small wherein each component, this results in having requirements at the higher level to the structure of product.Wherein, inductance will also meet power supply production
The requirement of product miniaturization, and the size of magnetic core can determine the volume size of inductance substantially.
In the prior art, I-type magnetic core is relatively common.In the manufacturing process of traditional I-type magnetic core, in view of I-shaped magnetic
The features of shape of core mostly uses greatly ferrite powder and is pressed into cylindrical type, then passes through grooving machine-cut at the intermediate position of cylinder
A groove appropriate is cut, inductance is made for coiling.The operational sequence of this manufacturing method is comparatively laborious, wastes time, and
And cutting step generates a large amount of leftover bits, waste of resource.Particularly with micro magnetic, the difficulty for cutting intermediate groove is larger,
High rejection rate, low production efficiency.And there is not yet the manufacture that I-type magnetic core is carried out with mold in the prior art.
In the prior art, the both ends of I-type magnetic core and intermediate groove are all cylindrical, from the point of view of amechanical angle, cylinder
Shape object is easy to roll, it is difficult to be clamped, and since cylinder has convex surface, attract mode to fix magnetic according to magnet
Core, convex contact face is poorer than planar stability, this causes magnetic core subsequently to make the inconvenient of inductance process.
