<p>PURPOSE:To obtain the title rotary transformer, having crosstalk and high degree of coupling even for multichannel, at low cost by a method wherein a coupled part is provided on both concentric circle and lengthwise direction. CONSTITUTION:The title rotary transformer is composed of a coaxial block 9, a coaxial block 10, and a coaxial block 11; and the coaxial blocks are arranged on a concentric circle respectively. According to this constitution, the opposing area per one coupling part is sufficiently provided by arranging coupling parts in two-dimensional form as shown in the diagram in order to make efficient use of the limited cubic volume. Also, if a first channel 3 and a second channel 4 are regarded as a pair, the channels 3 and 4 become completely same in the coaxial block 9. The inductance of each pair is made uniform even on the coaxial blocks 10 and 11. Accordingly, a rotary transformer having the coupling coefficient of uniform inductance can be obtained by arranging the coaxial blocks as shown in the diagram even in the case of a multichannel structure.</p> |
