<p>PURPOSE:To miniaturize a transmission device and to make it tightly sealed structure by constituting the circuit by means of a connection filter in which a primary coil and a secondary coil are respectively wound to both legs of a tripod magnetic core and a central leg is set to be a leakage shunt so as to adjust a connection coefficient. CONSTITUTION:Two pairs of E cores 21 are combined so that tripod legs face each other, for example, and gap members 24 and 25 are inserted between them. Then, the primary coil 22 and the secondary coil 23 are wound to both legs of the tripod magnetic core. The number of magnetic fluxes passing through the center leg in accordance with the size of the gap length of the center leg being the leakage shunt changes and accordingly the coupling degree of the primary coil 22 and the secondary coil 23 becomes large when the gap length of the center leg is large. Then, the coupling degree of the primary coil 22 and the secondary coil 23 becomes small when the gap length of the center leg is small so as to adjust the coupling coefficient. Thus, the transmission device can be miniaturized and it can be made into a tightly sealed structure.</p> |
