Abstract
The present invention relates to a current detection device having a multi-layered PCB core structure, and more particularly, to a current detection device having a multi-layered PCB core structure, by which a coil of a conventional current detection device is replaceable to make electrical properties constant and mass production is possible.
Claims3
A current detection device having a multi-layered PCB core structure, comprising:
- an upper coil pattern forming layer (100) made of a nonmagnetic material and having a plurality of coil patterns (120) connected alternately from top to bottom and vice versa through via holes (110);
- through-hole layers (200) positioned beneath the upper coil pattern forming layer with a central core layer (300) interposed therebetween, the through-hole layers (200) being horizontal to both sides of the central core layer, each of the through-hole layers (200) having a plurality of equal-sized via holes (210) formed at positions of the via holes (110);
- a central core layer (300) made of a core material and formed between the through-hole layers;
- and
- a lower coil pattern forming layer (400) positioned beneath the through-hole layers and the central core layer and made of a nonmagnetic material, the lower coil pattern forming layer (400) having a plurality of coil patterns (420) connected alternately from top to bottom and vice versa through a plurality of via holes (410),
- wherein the current detection device has one of circular, triangular, square, and polygonal shapes while having a central through-hole formed in the center thereof such that electric wires passes through the central through-hole.
