Title:
SIGNAL COUPLER
Document Type and Number:
WIPO Patent Application WO/2007/004419
Kind Code:
A1
Abstract:
In a signal coupler comprising magnetic cores (7a, 7b) where a power line (1) is inserted into an opening (8), a signal line (5) connected with a modem (2) is wound around contour portions (9a, 9b) and gaps (10a, 10b) are formed in a part of the contour portions (9a, 9b), a plurality of magnetic cores (7a, 7b) are arranged tightly such that the gaps (10a, 10b) are located at the same position. By having such a structure, high coupling efficiency can be attained without increasing the heights of the magnetic cores (7a, 7b).
