NON-REVERSIBLE CIRCUIT ELEMENT, COMMUNICATION DEVICE USING THIS, AND ASSEMBLING METHOD OF NON-REVERSIBLE CIRCUIT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a non-reversible circuit element having excellent non-reversible circuit characteristics and capable of reducing a cost.;SOLUTION: In the non-reversible circuit element, a magnetic rotator assembly 1 is accommodated in a holding tool. The holding tool includes a case 3 and a cover 4. Side walls 31 to 33 of the case 3 erect from the peripheral edge of a bottom surface 34, and separated from each other with a recessed part 36 formed at the end edge of the erected part. Side walls 41 to 43 of the cover 4 falls from the peripheral edge of the cover surface 34, and separated from each other with a protruded part 46 formed at the end edge of the falling part. The cover 4 is formed by permitting the protruded part 46 and the recessed part 36 fitted to each other and combined with the case 3. In this fitting state, the end surface 461 of the protruded part 46 and the inner surface 361 of the recessed part 36 make close contact with each other at a point P, and a gap G is produced between the end surface 462 of the protruded part 46 and the inner surface 362 of the recessed part 36.;COPYRIGHT: (C)2008,JPO&INPIT
