Abstract

924,549. Inductors. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 9, 1962 [Jan. 10, 1961], No. 876/62. Class 38 (2). A plastic holder 6 for fixing the position of a trimmer core 4 in the centre hole of a pot core 2 consists of an inner cylindrical body, which is threaded to receive a threaded portion 5 of the core, and an outer frusto-conical collar which has webs joining it to the inner body and slots 8 such that when the holder is pushed into the hole in the pot core the collar is compressed and the inner body is deformed by the force exerted through the webs.
