Title (EN) SIGNAL COUPLER
(FR) COUPLEUR DE SIGNAL
(JA) 信号結合装置
Abstract:
(EN) A signal coupler comprising magnetic cores (7a, 7b) wherein 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 provided in a part of the contour portions (9a, 9b). Since the plurality of magnetic cores (7a, 7b) are arranged tightly such that the gaps (10a, 10b) are located at the same position, high coupling efficiency can be attained without increasing the height of the magnetic cores (7a, 7b).
(FR) L'invention a trait à un coupleur de signal comprenant des centres magnétiques (7a, 7b) ; une ligne électrique (1) est insérée dans une ouverture (8), une ligne de signal (5) reliée à un modem (2) est enroulée autour des parties de contour (9a, 9b) et des intervalles (10a, 10b) sont prévus dans une partie du contour (9a, 9b). Puisque la pluralité des centres magnétiques (7a, 7b) est précisément positionnée de sorte que les intervalles (10a, 10b) soient situés à la même place, il est possible de parvenir à une forte efficacité de couplage sans augmenter la hauteur des centres magnétiques (7a, 7b).
(JA)  電力線1が開口部8に挿入されるとともに、モデム2と接続されている信号線5が輪郭部9a,9bに巻き付けられ、その輪郭部9a,9bの一部にギャップ10a,10bが施されている磁気コア7a,7bからなる信号結合装置において、ギャップ10a,10bの位置が同じ位置になるように、複数の磁気コア7a,7bを密着して設置する。これにより、磁気コア7a,7bの高さを高くすることなく、高い結合効率を得ることができる効果を奏する。
