HIGH-FREQUENCY COIL

摘要

PURPOSE:To prevent the generation of fitting backlashes due to micro-oscillation by fitting L-shaped projections at the corners of a sealed case in L-shaped through holes on a terminal plate having a winding part with pressure-contact completely. CONSTITUTION:L-shaped through holes 2a directed to the upper and lower surfaces of a terminal plate 2 is arranged between terminals 6 and the peripheral parts of corners of the terminal plate 2. Next, a winding part composed of a drum core 1 on which a coil 3 is wound is stuck and fixed to the terminal plate 2. The terminal plate 2 comprising the winding part thus composed is provided with L-shaped projections 4a which are inserted and fitted to the through holes 2a on the lower end of a sealed case 4 supported by a cap core 5 engaged spirally inside thereof. The projection 4a has the size 4b slightly larger than a length 2b of the through hole 2a and the projections are fitted with pressure contact and are fixed.
