摘要： PURPOSE:To provide a maintenance-free apparatus for transferring high-frequency power without the need of contact members such as a brush by using a transformer of which either or both of the primary and secondary are slidable on one or two parallel magnetic bars so that high-frequency power may be transferred between the primary and secondary. CONSTITUTION:The primary 1 and secondary 2 of a transformer are mounted on one or two parallel bars of a magnetic material in such a manner that either or both of the primary and secondary can slide on the bars. High frequency power and signals may be transferred between the primary and secondary units. The primary 1 and secondary 2 have coils 12 and 22 wound on cores 11 and 21, respectively. The primary is fixed on the parallel bars, while the secondary can slide on the bars. The secondary is fitted with a plastic bush on the sliding part at each end. The parallel bars 3 are made of a magnetic material such as ferrite or high-silicon steel.
